Healthcare Technology Management

1. Chapter Overview

Healthcare Technology Management (HTM) is the accountable, systematic approach to ensuring that cost-effective, efficacious, safe, and appropriate technology is available to meet the demands of quality patient care throughout its entire lifecycle — from needs assessment and procurement through operation, maintenance, and final disposal. On the MoE Revised Blueprint (2016 E.C.), HTM contributes 9 items under the Healthcare Technology Management and Regulations theme (18% total exam weight alongside regulatory and quality topics). This chapter is the capstone of the management and systems strand of biomedical engineering education: it asks not how does a ventilator work? but how does a hospital acquire, install, maintain, and retire that ventilator responsibly?

HTM sits at the intersection of clinical need, engineering competence, financial stewardship, and regulatory compliance. A biomedical engineer practicing HTM is properly called a clinical engineer — one who "supports and advances patient care by applying engineering and managerial skills to healthcare technology" (ACCE, 2015). The role has expanded from maintenance-only functions to encompass risk management, clinical governance, standards development, health technology assessment (HTA), procurement advisory, training, and integration with hospital information systems.

The WHO "How to Manage" Series for Healthcare Technology (Guides 1–6) provides the international framework referenced throughout Ethiopian BME curricula:

Primary sources: htm-lecture_one.txt, htm-mock-exam-q-a-2024.txt, WHO HTM Guides 1–6 (telegram-b2-htm-guide-*.json), THET equipment lifecycle materials, and integrated exit bank HTM items.

Relationship to other handbook chapters:

Exam character: HTM questions are predominantly definition, process-sequence, and role-identification items. The 2024 Jimma mock exam (htm-mock-exam-q-a-2024.txt) tests specification vs inventory vs warranty, competitive bidding rules, commissioning vs calibration, PM vs CM, inventory exclusions, and disposal authority — all reproduced and extended in Section 11 of this chapter.

2. Learning Outcomes

After completing this chapter, you should be able to:

1. Define HTM, clinical engineering, healthcare technology, medical device, and medical equipment with exam-precise distinctions.
2. Explain the HTM lifecycle and how planning, procurement, operation, maintenance, and disposal connect in a closed loop.
3. Apply the value equation $\text{Value} = \text{Benefit} / \text{Cost}$ to technology selection decisions.
4. Describe the HTM manager's role, organizational models, and four maintenance skill levels across the referral pyramid.
5. Conduct a structured needs assessment and translate clinical requirements into equipment specifications (not inventory records or warranties).
6. Prepare procurement documentation compliant with competitive bidding and tender evaluation committee processes.
7. Differentiate specification, inventory, warranty, commissioning, calibration, and decommissioning.
8. Design an equipment inventory registration policy — including what to register (ultrasound, CT, monitors) and what to exclude (aneroid sphygmomanometer).
9. Plan site preparation, installation, commissioning acceptance, and user training — including advantages of hands-on training.
10. Organize preventive, corrective, and predictive maintenance using a CMMS anchored on the equipment inventory.
11. Maintain maintenance records for trend analysis, regulatory audit, and lifecycle cost tracking.
12. Execute decommissioning and disposal following manufacturer instructions, local regulation, and government authority guidance.
13. Trace a complete hospital workflow from ventilator needs assessment through disposal.

3. Core Concepts

3.1 What Is Management?

Management is the efficient and effective utilization of resources in pursuit of organizational goals. Classic definitions emphasize:

• Planning — future-oriented decisions affecting long-term direction
• Organizing — structuring authority, subdivisions, and coordination
• Staffing — recruiting, training, and retaining suitable personnel
• Directing — leadership, communication, motivation, supervision
• Controlling — measuring performance against standards and taking corrective action

HTM applies these five functions to healthcare technology assets — a capital-intensive, safety-critical portfolio where failure has direct patient consequences.

3.2 Healthcare System Context

WHO defines a health system as all organizations, people, and actions whose primary intent is to promote, restore, or maintain health. Healthcare technology is indispensable to this system — it proliferates across primary, secondary, tertiary, and community/home care settings.

Ethiopia's health tier system maps technology needs to facility level:

HTM planning must align equipment standard lists with facility level — purchasing a CT scanner for a health center without radiologist, power, or maintenance capacity violates both planning and value principles.

3.3 Key Terminology — Medical Device vs Medical Equipment

Exit exams test this distinction repeatedly. Memorize the definitions from lecture and WHO/IMDRF frameworks:

Exam trap: An ultrasound machine is medical equipment (maintained, calibrated, inventoried). A surgical glove is a medical device but not equipment. An aneroid sphygmomanometer is a simple device — typically excluded from formal equipment inventory registration because it lacks the maintenance/calibration lifecycle burden of electromechanical equipment (mock exam Q6).

3.4 Why Acquire Healthcare Technology?

Technology acquisition serves five strategic purposes (lecture):

1. Improve diagnostic, therapeutic, or rehabilitation efficiency
2. Increase health system cost-effectiveness or reimbursement
3. Reduce risk exposure and eliminate errors
4. Attract high-quality professionals
5. Expand service area or beneficiary base

Consequences of poor acquisition include rising total equipment cost, device failure impacts, operator error incidents, regulatory non-compliance, and public loss of confidence. Government policies, professional bodies, and insurers demand active lifecycle management from purchase to disposal.

3.5 Value in Healthcare

Healthcare delivery is costly; society demands access, quality, and sustainability simultaneously. Value combines better care with affordable cost:

Benefit includes clinical outcomes, access, safety, and staff satisfaction. Cost includes capital purchase, installation, training, consumables, maintenance, downtime, and disposal. A device with high clinical benefit but unsustainable total cost of ownership (TCO) has low value in resource-limited settings.

Biomedical engineers add value by:

• Selecting appropriate technology for facility level
• Ensuring safe installation and commissioning
• Maintaining equipment availability through PM
• Training users to prevent operator-error incidents
• Standardizing models to reduce spare parts and training burden
• Supporting evidence-based replacement decisions

3.6 Healthcare Technology Management — Formal Definition

ECRI Institute defines HTM as:

"An accountable, systematic approach to assuring that cost-effective, efficacious, safe, and appropriate technology is available to meet the demands of quality patient care."

HTM is synonymous with Medical Equipment Management (MEM) in many curricula. It encompasses the twin remits:

1. Supporting and advancing care — clinical engineering at point of need
2. Equipment management — lifecycle asset stewardship

3.7 The HTM Lifecycle

The HTM lifecycle is not the marketing product life cycle (introduction → growth → maturity → decline). It is the customer/hospital perspective on managing physical hardware:

NEEDS ASSESSMENT → PLANNING & BUDGETING → SELECTION & SPECIFICATION
        ↓
   PROCUREMENT & LOGISTICS → SITE PREPARATION → INSTALLATION
        ↓
   COMMISSIONING → TRAINING → OPERATION & SAFETY
        ↓
   PREVENTIVE / CORRECTIVE / PREDICTIVE MAINTENANCE
        ↓
   DECOMMISSIONING → DISPOSAL → REPLACEMENT (cycle restarts)

WHO Guide 1 lists the coordinating activities:

• Gathering reliable information about equipment (inventory)
• Planning technology needs and allocating sufficient funds
• Purchasing suitable models and installing them effectively
• Providing sufficient resources for their use
• Operating them effectively and safely
• Maintaining and repairing equipment
• Decommissioning, disposing, and replacing obsolete items
• Ensuring staff have skills to get best use from equipment

Each phase produces documentation that feeds the next — the inventory and CMMS are the institutional memory.

3.8 HTM Manager Role

The HTM Manager (or Head of Clinical Engineering / Biomedical Engineering Department) is the accountable leader who:

• Reports to hospital administration with authority over technical services
• Develops HTM policy aligned with national health and equipment policy
• Leads annual planning and budgeting for technology
• Oversees inventory, CMMS, and maintenance performance indicators
• Advises procurement committees on specifications and bid evaluation
• Ensures regulatory compliance (EFDA registration, radiation safety, disposal rules)
• Manages human resources across four skill levels
• Liaises with clinical departments, finance, stores, and external service providers

Maintenance staff should report to the HTM Manager — not to individual clinical departments — to maintain impartiality, standardization, and spare parts economy.

3.9 Framework Requirements — Policy, Regulation, Standards

National HTM requires layered governance (WHO framework):

Standardization of equipment models limits variety — concentrating on fewer makes/models per category increases technical skills, decreases costs and logistics (lecture). A hospital with seven ventilator brands faces seven training curricula and seven spare parts pipelines.

3.10 Four Maintenance Skill Levels

WHO and GTZ define skill levels for maintenance work division:

The inverted pyramid of personnel: many Level 1 staff, fewer Level 4 specialists. Training investment increases with skill level breadth.

3.11 HTM Service Provider Models

Vital equipment requiring 24/7 availability should use maintenance agencies with guaranteed response times — often hybrid in-house + OEM contract models.

4. Technical Deep Dive

4.1 Planning and Assessment

Planning is the first and most critical lifecycle phase. Inadequate planning is the root cause of idle equipment, missing spare parts, and budget overruns visible across developing-country health systems.

4.1.1 The Annual Planning Cycle

WHO Guide 2 establishes a repeating cycle:

1. Review past performance, problems, and unmet needs
2. Identify solutions and set specific goals for the coming year
3. Prepare an annual action plan with timelines and responsibilities
4. Monitor implementation through the year
5. Restart with next year's review

This cycle integrates with the hospital planning cycle and national health sector development plans.

4.1.2 Needs Assessment Steps

1. Define the clinical problem — e.g., ICU mortality from respiratory failure; current ventilator fleet age and downtime
2. Map existing inventory — quantity, functional status, location, age, maintenance history
3. Identify gaps against standard equipment lists for facility level (MoH/Ethiopian essential equipment lists)
4. Consult stakeholders — ICU physicians, anesthetists, nurses, finance, engineering, procurement
5. Prioritize against budget constraints and strategic plan
6. Document justification — epidemiology, case load, referral patterns, staff capability

4.1.3 Stakeholders in Equipment Planning

4.1.4 Health Technology Assessment (HTA)

HTA is the systematic evaluation of properties, effects, and impacts of health technology — extending beyond purchase price to clinical effectiveness, safety, cost-effectiveness, and organizational impact. HTA answers: Should we buy this technology at all? before specification answers: Which model meets our needs?

HTA inputs include published evidence, local disease burden, alternative technologies, and infrastructure readiness. In Ethiopia, HTA capacity is developing; exit exams may test the concept and its role in rational policy rather than full economic modeling.

4.2 Budgeting and Financing

Equipment costs extend far beyond purchase price. Total Cost of Ownership (TCO) includes:

4.2.1 Budget Categories

WHO Guide 6 recommends tracking expenditure against inventory categories and reporting cost per functional device per year — a metric that exposes under-maintained fleets.

4.2.2 Budgeting Rule of Thumb

A widely cited planning guideline (WHO/THET materials): allocate approximately 8–12% of original equipment value per year for maintenance and operational support in resource-limited settings — higher for imaging and ICU devices, lower for simple durable goods. Exact percentages vary; exams test the principle that maintenance must be budgeted at procurement time, not after failure.

4.2.3 Contract Negotiation Points

Procurement contracts should explicitly assign responsibility for:

• Installation and commissioning costs
• Warranty period and covered components
• Post-warranty maintenance (in-house vs vendor contract)
• Spare parts availability and price cap period
• Training (number of staff, refresher courses)
• Performance penalties for delayed delivery

4.3 Technology Assessment and Selection

4.3.1 Specification — The Critical Document

The specification is the detailed technical description of medical equipment required before procurement or acquisition (mock exam Q1 — Answer: Specification, not inventory, warranty, or decommissioning).

A specification includes:

• Intended clinical use and performance requirements
• Technical parameters (measurable — e.g., tidal volume range, accuracy, alarm limits)
• Safety standards compliance (IEC 60601-1, ISO requirements)
• Power, gas, network, and environmental requirements
• Training and documentation language requirements
• Warranty and post-warranty service terms
• Acceptance test criteria for commissioning

Purpose of specification (mock Q2): For acquisition of quality product matched to need — not vendor relationship management or creating competition alone (though competition follows from fair specification).

Specifications must be performance-based where possible — describing what the device must do, not which brand to buy — to comply with competitive bidding law.

4.3.2 Specification vs Inventory vs Warranty

Exam trap: Inventory describes what you have; specification describes what you need. Warranty is a contractual guarantee, not a procurement prerequisite document.

4.3.3 Selection Criteria Matrix

Value assessment applies: highest benefit/cost ratio wins — not lowest purchase price alone.

4.3.4 Health Technology Assessment (HTA)

HTA is multidisciplinary policy analysis examining medical, economic, social, and ethical implications of adopting a health technology. HTA informs decisions — it does not make them.

HTA applies to drugs, devices, procedures, and organizational systems. At micro-level: should this hospital buy this CT scanner? At macro-level: national priority-setting for limited budgets.

4.4 Procurement and Logistics

4.4.1 National Procurement Principles

Ethiopian public procurement requires transparent, competitive processes. From mock exam Q3 — NOT part of proper regulation:

• Procurement based on higher officials' decision alone (wrong)

Correct regulatory elements:

• Procurement based on competitive bidding
• Cost as one of evaluation criteria in bid documents
• Decision by tender evaluators committee (technical + financial evaluation)

4.4.2 Procurement Stages

REQUISITION → SPECIFICATION APPROVAL → TENDER ADVERTISEMENT
      ↓
BID RECEIPT → BID OPENING → TECHNICAL EVALUATION
      ↓
FINANCIAL EVALUATION → COMMITTEE RECOMMENDATION → AWARD
      ↓
CONTRACT SIGNING → PAYMENT TERMS → DELIVERY SCHEDULE

4.4.3 Competitive Bidding Evaluation

Typical weighted scoring:

• Technical compliance — pass/fail against mandatory specification clauses
• Technical merit — scored features exceeding minimum
• Price — lowest compliant bid advantage
• Local support — service center, spare parts stock
• Delivery time — critical for emergency purchases

The HTM Manager provides technical evaluation; finance provides financial evaluation; the committee integrates both. No single official should bypass the committee.

4.4.4 Logistics

After award:

• Inspect shipment against packing list on arrival
• Document transport damage immediately
• Secure storage in controlled environment (temperature, humidity, theft)
• Verify serial numbers match contract before installation scheduling
• Coordinate installation team (vendor + in-house HTM + clinical users)

4.5 Installation and Commissioning

4.5.1 Site Preparation

Site preparation prepares the installation area with required facilities before equipment arrives (mock Q11 — Answer: prepare area with required facilities).

Checklist for critical care equipment (ventilator/ICU bed location):

Site preparation is not user training, cost reduction, or fulfilling user interest alone — it is engineering readiness.

Installation tasks include (mock Q10 — decommissioning is NOT installation):

• Site preparation
• Fulfillment of manufacturer installation instructions
• Startup calibration and commissioning
• Physical assembly and utility connection

4.5.2 Commissioning vs Calibration

Exam trap: Commissioning = acceptance and handover process. Calibration = measurement accuracy verification. A ventilator can be commissioned (all functions work) yet still need calibration (delivered tidal volume matches set value).

Example calibration task (mock Q16): Adjusting O₂ sensor and tidal volume for mechanical ventilator.

4.5.3 Acceptance Testing Protocol

Minimum commissioning documentation:

1. Incoming inspection report
2. Installation checklist signed by HTM and vendor
3. Electrical safety test (earth continuity, leakage current per IEC 60601)
4. Functional performance test against specification annex
5. Alarm verification at limits
6. Clinical sign-off by department head
7. Asset tag assignment and CMMS entry
8. User training completion record
9. Warranty start date confirmation
10. Final handover certificate

4.6 Training and Skill Development

4.6.1 Training Categories

4.6.2 Hands-On Training Advantages

Mock exam Q14 — primary advantage of hands-on training:

It can simulate real-world scenarios — trainees practice on actual or simulated equipment under supervised conditions, building muscle memory for alarm response and mode changes that lecture-only training cannot provide.

Other options in the question were distractors:

• "Learn at own pace" — describes self-paced e-learning, not hands-on
• "No specialized equipment needed" — false; hands-on requires equipment
• "Cost-effective" — hands-on is typically more expensive due to trainer time and device allocation

WHO emphasizes cascade training: vendor trains key staff (train-the-trainer); key staff train ward bulk users; HTM trains maintainers.

4.6.3 Training Records

Maintain: trainee name, date, competency checklist, trainer signature, equipment model covered. Records support incident investigation and accreditation audits.

4.7 Operation and Safety

4.7.1 First Rule Before Operation or Maintenance

Mock Q13: Before any operation or maintenance activity, read manufacturer instructions and gain sufficient understanding — not colleague opinion, previous experience alone, or immediate outsourcing.

The Instructions for Use (IFU) is a legal document defining intended use, contraindications, cleaning, maintenance intervals, and disposal.

4.7.2 Operational Safety Framework

• Risk management — identify hazards (electrical, pneumatic, radiation, infection)
• Standard Operating Procedures (SOPs) — ward-level protocols for daily checks
• Incident reporting — device-related adverse events to HTM and EFDA vigilance
• Recall management — manufacturer safety notices acted upon fleet-wide via inventory query
• Electrical safety testing — periodic per IEC 62353 or local protocol

4.7.3 Equipment Categories by Clinical Use

From lecture — four application categories tested conceptually:

1. Therapeutic — e.g., linear accelerator, defibrillator
2. Prosthetic — e.g., braces, prosthetic limbs
3. Diagnostic — e.g., X-ray, MRI, ultrasound
4. Monitoring — e.g., telemetry, vital signs monitors, ventilator monitoring parameters

4.8 Maintenance and Repair

4.8.1 Maintenance Types

PM activities (mock Q — welding excluded):

• Equipment functionality inspection
• Periodic cleaning
• Lubrication and mechanical integrity test
• Alarm and safety checks
• Filter replacement

NOT PM: Welding, major spare part replacement after failure, software installation for fault repair — these are corrective or major repair.

4.8.2 Why Plan Maintenance?

Mock Q7: Purpose of planning maintenance — to improve efficiency (not decrease productivity, increase downtime, or increase cost).

Planned PM reduces unplanned downtime, extends equipment life, maintains measurement accuracy, and satisfies accreditation requirements.

4.8.3 Maintenance Records

Mock Q9: Records purpose — track maintenance activities and identify trends (failure patterns, high-cost assets, PM compliance rates).

Every maintenance record should link to inventory asset ID and include:

• Date, technician, work type (PM/CM/calibration)
• Parts replaced, test results
• Time to repair (MTTR), downtime duration
• Next PM due date

Basis of maintenance records system: the Equipment Inventory (WHO Guide 5).

4.8.4 CMMS — Computerized Maintenance Management System

A CMMS is software that integrates:

• Asset registry (from inventory)
• PM schedule generation by date, meter reading, or manufacturer interval
• Work order management — request, assign, complete, close
• Spare parts inventory linked to equipment model
• Cost tracking — labor, parts, contractor invoices
• Reporting — PM compliance %, MTBF, MTTR, equipment availability

INVENTORY DATABASE ←→ CMMS ←→ WORK ORDERS → TECHNICIANS
        ↓                ↓
   MAINTENANCE        SPARE PARTS
   HISTORY            STORES

Without CMMS, PM schedules live on paper and are missed; trends cannot be analyzed. CMMS is the operational engine of HTM — not a clinical device focus but a management system examined conceptually.

4.8.5 Spare Parts Strategy

Mock Q17: Ensure spare parts availability by ordering in proper quantity as needed based on PM schedule and criticality — not zero stock (just-in-time only) nor hoarding without plan.

Critical spare parts for vital equipment (ventilator boards, O₂ sensors) should be stocked on site; consumable parts ordered against PM calendar.

4.8.6 Predictive Maintenance

PdM uses equipment-generated data:

• Ventilator: internal hours counter, compliance monitoring trends
• Imaging: tube heat unit logging
• Networked devices: remote error log polling

When trend exceeds threshold, CMMS generates work order before clinical failure. PdM reduces emergency CM but requires data infrastructure — increasingly relevant as devices connect to hospital networks.

4.9 Decommissioning and Disposal

4.9.1 Decommissioning Definition

Decommissioning is total removal of medical equipment from the health facility due to technical and clinical obsolescence — beyond economical repair, safety risk, or replaced by superior technology (mock Q18).

Not decommissioning:

• Calibration — accuracy adjustment during active service
• Disposal — the physical end step after decommissioning decision
• Shipment — logistics only

4.9.2 Decommissioning Decision Criteria

• Repair cost exceeds replacement threshold (e.g., >50% of new unit price)
• Manufacturer withdraws support/parts
• Safety standards updated — device cannot comply
• Repeated identical failures despite CM
• Clinical obsolescence — cannot support current ventilation modes required

4.9.3 Disposal Methods

Mock Q — proper disposal method selection: All are correct:

• Consult concerned government authority (EFDA, environmental agency)
• Follow manufacturer instructions (hazardous components, battery removal)
• Follow local government regulation (e-waste, radiation sources, sharps)

Disposal routes by equipment type:

Never dispose of functional equipment without inventory write-off, data sanitization (if networked), and authority notification where required.

5. Equipment and Device Focus

This section addresses HTM systems and workflows — not individual clinical device physiology (see Chapters 5–7). The three management pillars examined are CMMS, inventory systems, and procurement workflow.

5.1 Equipment Inventory System

5.1.1 Definition and Purpose

Medical equipment inventory is the technical assessment and documentation of available healthcare technology on hand — providing type, quantity, and current operating status (mock Q4 — Answer: Medical equipment inventory).

Primary purpose (mock Q5): To track medical equipment information and archives — not pharmaceutical supplies, staff reduction, or maintenance cost minimization alone.

5.1.2 Minimum Inventory Data Fields

WHO Guide 3 minimum data at registration:

5.1.3 Include vs Exclude from Registration

Rationale for exclusion: Items without significant calibration, maintenance, or training lifecycle burden — or consumables tracked by stores/pharmacy systems — should not dilute the equipment inventory used for PM scheduling and asset valuation.

5.1.4 Inventory Update Cycle

• Full physical audit — annual (cross-check floor vs database)
• Continuous update — on acquisition, transfer, status change, decommissioning
• Integration with CMMS — single source of truth; duplicate spreadsheets cause drift

5.2 CMMS Functional Architecture

Key performance indicators (KPIs):

\text{PM Compliance} = \frac{\text{PM completed on time}}{\text{PM scheduled}} \times 100%

Target: critical equipment availability ≥ 95%; PM compliance ≥ 90% (institutional benchmarks vary).

5.3 Procurement Workflow System

End-to-end procurement workflow (public hospital model):

CLINICAL NEED → HTM NEEDS ASSESSMENT → DRAFT SPECIFICATION
        ↓
HTM + USER REVIEW → PROCUREMENT REQUISITION → BUDGET CONFIRMATION
        ↓
TENDER DOCUMENT (spec + terms) → ADVERTISE → BID OPENING
        ↓
TECHNICAL EVALUATION (HTM-led) → FINANCIAL EVALUATION → AWARD
        ↓
CONTRACT (warranty + training + installation) → DELIVERY
        ↓
RECEIVING INSPECTION → INVENTORY REGISTRATION → INSTALLATION
        ↓
COMMISSIONING → TRAINING → CMMS PM SCHEDULE ACTIVATED

Document control points:

5.4 Warranty Management

Warranty is not a procurement specification — it is a contractual condition activated at acceptance:

• Define warranty start (typically commissioning sign-off, not shipment)
• Track expiry in CMMS for proactive contract negotiation
• During warranty: CM often vendor responsibility — log all calls for trend evidence at expiry negotiation
• Extended warranty vs in-house maintenance cost comparison before expiry

6. Practical BME Perspective

6.1 The Clinical Engineer as Lifecycle Steward

A BME graduate entering hospital service inherits equipment others purchased — often without specifications, training, or spare parts. The practical mission is converting reactive chaos into planned HTM:

1. Baseline inventory — you cannot manage what you do not know you have
2. Triage functional status — critical/non-critical; functional/broken
3. Implement PM schedule — even paper-based before CMMS
4. Stop inappropriate donations — apply WHO donation guidelines
5. Engage procurement early — specifications before budget is spent

6.2 Complete Hospital Workflow Example — Ventilator Procurement to Disposal

This worked example traces one ICU ventilator through the full HTM lifecycle at a 200-bed regional referral hospital in Ethiopia.

Phase 1 — Needs Assessment (Month 1)

Trigger: ICU expansion from 8 to 12 beds; existing fleet of 6 ventilators (average age 9 years, 40% downtime on two units).

HTM actions:

• Inventory query: 6 ventilators — 4 functional, 2 non-functional (obsolete parts unavailable)
• Gap analysis: 12 ICU beds require minimum 8 ventilators (1:1.5 ratio per local ICU guideline) + 2 reserve = 10 ventilators; gap = 4 new units
• HTA summary: new ventilators reduce referral transfers; TCO favorable over 10 years vs repair of obsolete units
• Stakeholder meeting: ICU head defines needs — invasive/non-invasive modes, pediatric adapter capability, battery backup ≥ 30 min, display language
• Submitted to hospital planning committee with 3-year capital plan priority ranking

Phase 2 — Specification Development (Month 2)

HTM drafts performance specification:

• Mode list: AC, SIMV, CPAP, BiPAP, PRVC
• Tidal volume range: 50–1500 mL; accuracy ±10% or ±50 mL
• PEEP: 3–20 cmH₂O
• FiO₂ range: 21–100%; O₂ sensor calibration interval ≤ 12 months
• Alarms: apnea, high pressure, low pressure, disconnect — audible and visual
• Electrical: 230 V ±10%, 50 Hz; dedicated UPS circuit; ≤ 800 VA
• Medical air and O₂: pipeline 280–600 kPa; DISS fittings
• Standards: IEC 60601-1, ISO 80601-2-12
• Training: 2 ICU physicians + 6 nurses + 2 HTM staff — hands-on, ≥ 3 days
• Warranty: ≥ 3 years parts and labor; local service agent named
• Commissioning acceptance tests attached as annex

Specification approved by tender committee — not branded to single manufacturer.

Phase 3 — Budgeting (Month 2–3)

Finance allocates:

• CAPEX: 4 ventilators × unit cost + 15% contingency for installation/training
• OPEX reserve: 10% of capital per year × 4 units for maintenance/consumables
• Replacement reserve entry in 10-year equipment plan

Phase 4 — Tender and Procurement (Months 3–5)

• Tender advertised per Federal Public Procurement Proclamation
• Four bids received; opening committee records prices
• Technical evaluation (HTM-led): Bid B and D pass mandatory specs; Bid A fails battery backup; Bid C fails ISO citation
• Financial evaluation: Bid D lowest compliant price
• Tender committee recommends Bid D; hospital board approves award
• Contract includes: delivery in 8 weeks, installation, commissioning, training, 3-year warranty, spare parts price list frozen for 5 years

Phase 5 — Logistics and Site Preparation (Month 6)

Before delivery:

• HTM verifies 4 ICU bed locations: electrical outlet tested, UPS installed, O₂ and medical air pressure verified at 400 kPa, network port active
• Site preparation checklist signed

On delivery:

• Goods inspected — one crate corner dented; inner unit intact; documented with photos
• Serial numbers recorded pending inventory registration

Phase 6 — Installation and Commissioning (Month 6–7)

Vendor technician with HTM staff:

• Assembly per IFU; pipeline connected; electrical safety test passed (earth < 0.2 Ω, leakage < 500 µA)
• Functional tests: tidal volume verification at 500 mL setting using test lung — measured 485 mL (within spec)
• O₂ sensor calibrated at 21% and 100%
• All alarms tested at limits
• 4-hour burn-in run without fault
• Commissioning report signed — clinical handover authorized
• Warranty start date: commissioning sign-off

Distinction documented: Commissioning confirmed system readiness; calibration confirmed measurement accuracy of O₂ and volume delivery.

Phase 7 — Training (Month 7)

• Vendor 3-day hands-on course in ICU — simulated power failure, alarm response, circuit change drills
• HTM records trainee competency checklists — 10 staff certified
• Cascade: certified nurses train remaining ward staff over 2 weeks
• Training materials filed in HTM library and ward SOP binder

Phase 8 — Inventory and CMMS Activation (Month 7)

Four assets registered:

CMMS PM schedule: quarterly inspection + annual calibration + filter replacement per IFU.

Phase 9 — Operation and Safety (Years 1–8)

• Daily user checks: circuit integrity, alarm test, backup battery indicator
• HTM electrical safety annual
• Incident: HTM-V-042 high-pressure alarm false trigger — CM work order; expiratory valve replaced; root cause logged
• Predictive element: CMMS flags increasing valve replacement frequency on same unit — investigated at Year 5 PM

Phase 10 — Maintenance Record (Illustrative excerpt)

Trend analysis at Year 7: HTM-V-042 cumulative repair cost 45% of replacement — flagged for replacement planning.

Phase 11 — Decommissioning and Disposal (Year 10)

HTM-V-042 (oldest in new batch after heavy use):

• Manufacturer announces model end-of-support
• Two major board failures in 6 months — repair quote = 60% of new unit
• Decommissioning committee (HTM + ICU + finance): decommission approved
• Patient data/log cleared from device memory
• O₂ cell removed (recycling)
• EFDA and hospital asset management notified
• Disposal via licensed e-waste contractor per environmental regulation
• Inventory status → Decommissioned; CMMS closed; replacement requisition initiated

Lifecycle closed — needs assessment begins again.

6.3 Integration with Hospital Engineering (Chapter 9)

Ventilator workflow depends on Chapter 9 infrastructure:

• Medical air oil-free and dried
• O₂ pipeline pressure and alarm panel functional
• UPS on essential circuit
• ICU negative/positive pressure per infection control design

HTM cannot commission a ventilator in a bed location without verified utilities — coordination with hospital engineering is mandatory.

6.4 Ethiopian Context

• EFDA regulates medical device market authorization — procurement must verify registration
• Public procurement law mandates competitive bidding — no official-only awards
• WHO HTM Guides are curriculum standard at AAU/Jimma BME programs
• Resource constraints make standardization and TCO analysis essential — cheapest import without service network has negative value
• Donation management — common source of equipment inconsistency; apply WHO Medical Device Donation Guidelines before acceptance

6.5 Common Failure Modes in HTM Practice

7. Frequently Tested Concepts

7.1 High-Yield Topics — Rapid Table

7.2 Detailed Exam Callouts

EXAM CALLOUT — Specification vs Inventory vs Warranty (mock Q1–5):

Specification = detailed technical description before procurement. Inventory = documentation of equipment on hand (type, quantity, status). Warranty = supplier guarantee with purchase — duration and defect coverage.

Key insight: Exams swap these three terms in stems. Read the verb: "outlined as pre-requirement for procurement" → specification. "technology on hand" → inventory. "supplier guarantee period" → warranty.

EXAM CALLOUT — Competitive Bidding (mock Q3):

Answer: Procurement is NOT based on higher officials' decision alone.

Key insight: Valid public procurement requires competitive bidding, cost as evaluation criterion, and tender evaluators committee decision. Political purchase bypass is explicitly the wrong answer.

EXAM CALLOUT — Inventory Exclusion (mock Q6):

Answer: Aneroid sphygmomanometer cannot be included in equipment inventory registration.

Key insight: Include electromechanical equipment requiring PM/calibration (ultrasound, CT, monitors). Exclude simple mechanical devices without maintenance lifecycle. Implants and disposables also excluded.

EXAM CALLOUT — PM vs CM (mock Q7–9):

PM = scheduled prevention (inspection, cleaning, lubrication, functionality test). CM = repair after breakdown. Welding and major part replacement after failure = CM, NOT PM. Maintenance records = trend analysis and activity tracking.

Key insight: "Planning maintenance" improves efficiency — never choose "increase downtime" distractors.

EXAM CALLOUT — Commissioning vs Calibration (mock Q10–12, Q15–16):

Commissioning = continuous performance/functionality checking for full handover after installation. Calibration = adjusting/verifying measurement accuracy against clinical standards. Site preparation = preparing installation area with required utilities/facilities. Installation excludes decommissioning.

Key insight: Ventilator example: commissioning proves alarms and modes work; calibration proves tidal volume and FiO₂ readings are accurate.

EXAM CALLOUT — Operation Safety and Training (mock Q13–14):

Before operation/maintenance: Read manufacturer instructions — first and mandatory. Hands-on training advantage: Simulates real-world scenarios — not "cost-effective" or "no equipment needed."

Key insight: IFU compliance is the baseline legal and safety defense in incident investigation.

EXAM CALLOUT — Decommissioning and Disposal (mock Q18–19):

Decommissioning = total removal from facility due to technical/clinical obsolescence. Disposal method: consult government authority + follow manufacturer + follow local regulation = all correct.

Key insight: Decommissioning is the decision; disposal is the physical action. Calibration occurs during active service, not at end-of-life.

EXAM CALLOUT — Value Equation (lecture):

Value = Benefit / Cost

Key insight: Lowest purchase price ≠ highest value. A cheap ventilator without local service network increases cost (downtime) and reduces benefit (unavailability) — low value.

EXAM CALLOUT — Medical Device vs Medical Equipment (lecture):

Medical equipment requires calibration, maintenance, repair, training, decommissioning — managed by clinical engineers. Medical device is broader; includes disposables and implants excluded from equipment inventory.

Key insight: "Does not achieve primary action by pharmacological, immunological, or metabolic means" defines medical device boundary.

EXAM CALLOUT — HTM Definition (ECRI):

Accountable, systematic approach assuring cost-effective, efficacious, safe, appropriate technology for quality patient care.

Key insight: HTM = MEM; spans full lifecycle, not maintenance only.

EXAM CALLOUT (HTA lecture): HTA examines efficacy, effectiveness, cost, ethics, and social impact — not purchase price alone. HTA supplies evidence; policy makers decide.

EXAM CALLOUT (HTM guide series): Specification is pre-purchase; inventory is post-acquisition; commissioning is post-installation acceptance — three different documents at three lifecycle stages.

10. Chapter Summary

Healthcare Technology Management is the lifecycle stewardship of medical equipment — ensuring the right technology is available, safe, and sustainable from needs assessment through disposal. The ECRI definition emphasizes accountable, systematic management for cost-effective, efficacious, safe, appropriate technology.

Core distinctions drive exam success:

• Specification (pre-purchase need) ≠ inventory (post-purchase record) ≠ warranty (contractual guarantee)
• Medical equipment (maintained by clinical engineers) ⊂ medical device (broader regulatory category)
• Commissioning (system handover) ≠ calibration (measurement accuracy)
• PM (scheduled) ≠ CM (breakdown) ≠ PdM (condition-based)

Value = Benefit / Cost — guides rational selection beyond lowest price.

The HTM Manager leads planning, inventory, CMMS, procurement technical evaluation, and maintenance organization across four skill levels. WHO Guides 1–6 provide the international framework; Ethiopian context adds EFDA registration and competitive public procurement.

CMMS anchored on equipment inventory schedules PM, tracks CM, manages spare parts, and generates trend data. Simple devices like aneroid sphygmomanometers are excluded from formal inventory; ultrasound, CT, and monitors are included.

Operation safety begins with reading the IFU. Hands-on training simulates real clinical scenarios. Maintenance records enable trend analysis. Decommissioning removes obsolete equipment; disposal follows government authority, manufacturer, and local regulation.

The ventilator workflow example demonstrates integration: needs assessment → specification → tender → site preparation → installation → commissioning → calibration → training → CMMS PM → CM events → decommissioning → disposal → replacement cycle.

HTM connects to Hospital Engineering (utilities for installation), Regulations (EFDA, procurement law), and Clinical practice (user training, safety). Master the process sequences and terminology — HTM exit items reward systematic thinking over device physics depth.

11. Exam Practice

11.1 Basic Questions (10 MCQs)

B1. The document that provides detailed technical description of medical equipment as a pre-requirement for procurement is called:

(a) Inventory
(b) Warranty
(c) Specification
(d) Decommissioning

Solution: (c) Specification. Specification defines required performance before acquisition. Inventory documents existing assets; warranty is a purchase guarantee; decommissioning is end-of-life removal.

B2. What is the primary purpose of a medical equipment inventory system in health facilities?

(a) To reduce hospital staff
(b) To track all pharmaceutical supplies
(c) To track medical equipment information and archives
(d) To minimize maintenance cost

B3. Maintenance performed after total equipment breakdown is called:

(a) Preventive maintenance
(b) Scheduled maintenance
(c) Corrective maintenance
(d) User-level maintenance

Solution: (c) Corrective maintenance (CM). Triggered by failure. PM is scheduled before failure.

B4. The formula for value in healthcare technology management is:

(a) Value = Cost × Benefit
(b) Value = Benefit / Cost
(c) Value = Cost − Benefit

11.2 Intermediate Questions (10 MCQs)

I1. What is the main advantage of preparing a medical equipment specification for a health facility?

(a) Acquisition of quality product matched to need
(b) Creating positive vendor relationships only
(c) Keeping health professionals' personal interest
(d) Creating competition among suppliers as the sole goal

Solution: (a). Specification ensures quality product acquisition aligned to clinical and technical need (mock Q2). Competition follows from fair procurement but is not the primary purpose of specification.

Solution: (b). Welding and major part replacement after failure is corrective maintenance, not scheduled PM.

I4. Why is it important to keep records of maintenance work?

(a) To increase downtime
(b) To decrease productivity
(c) To improve efficiency only with no documentation need
(d) To track maintenance activities and identify trends

Solution: (d). Records enable trend analysis, PM compliance audit, and lifecycle cost decisions (mock Q9).

I5. What is the purpose of site preparation before equipment installation?

(a) To prepare the area with required facilities (power, gases, space)
(b) To fulfill user personal interest only
(c) To train healthcare professionals before delivery
(d) To reduce installation cost by skipping utilities

Solution: (a). Engineering readiness — electrical, gas, space, HVAC per manufacturer requirements (mock Q11).

I6. Which activity is NOT part of medical equipment installation?

(a) Site preparation
(b) Decommissioning
(c) Fulfillment of manufacturer installation instructions
(d) Startup calibration and commissioning

Solution: (b) Decommissioning. End-of-life removal — opposite of installation (mock Q10).

I7. An advantage of hands-on training for medical equipment safety is that it:

(a) Requires no specialized equipment

(a) It ensures equipment works properly with clinical/metrology standards
(b) It increases downtime intentionally
(c) It decreases productivity
(d) It eliminates need for PM

Solution: (a). Calibration verifies measurement accuracy — e.g., ventilator tidal volume and FiO₂ (mock Q15).

I9. How should spare parts availability be ensured for proper maintenance?

(a) Never keep any spare parts
(b) Rely exclusively on just-in-time with zero stock always
(c) Order in proper quantity as needed based on PM schedule and criticality
(d) Wait until breakdown then emergency import only

Solution: (c). Planned stocking against PM and criticality — mock Q17.

I10. The purpose of planning maintenance work is to:

(a) Decrease productivity
(b) Increase downtime
(c) Improve efficiency
(d) Increase unplanned costs

Solution: (c) Improve efficiency (mock Q7). Planned PM reduces emergency downtime and optimizes resource use.

11.3 Advanced Questions (10 MCQs)

A1. A hospital CMMS shows ventilator HTM-V-012 had four expiratory valve replacements in 8 months despite quarterly PM compliance. The most appropriate HTM action is:

(a) Stop all PM since it is ineffective
(b) Analyze trend for root cause; evaluate decommissioning/replacement against repair cost threshold
(c) Remove from inventory to hide failure pattern
(d) Extend PM interval to once yearly to reduce cost

Solution: (b). Trend data drives lifecycle decision — repeated CM costs trigger replacement analysis per value/TCO principles. PM compliance confirms PM was done; problem is asset deterioration or design weakness.

A2. During tender evaluation, Bid A has lowest price but lacks ISO 80601-2-12 compliance mandatory in the specification. Bid B is 15% higher and fully compliant with local service agent. Correct action:

(a) Award Bid A — lowest price always wins
(b) Reject Bid A on technical fail; evaluate Bid B on merit
(c) Split award between both
(d) Cancel procurement permanently

Solution: (b). Mandatory technical requirements are pass/fail — non-compliant bid rejected regardless of price. Safety and performance standards are non-negotiable.

A3. A donated ventilator arrives without IFU, spare parts list, or local service support. WHO donation guidelines recommend:

(a) Accept all donations to maximize asset count
(b) Refuse or accept only if complete, functional, appropriate for facility level, and sustainable
(c) Accept and use until first breakdown then discard
(d) Accept and never register in inventory

Solution: (b). WHO Medical Device Donation Guidelines require appropriateness, completeness, and sustainability — inappropriate donations reduce value and increase CM burden.

A4. Predictive maintenance differs from preventive maintenance because PdM:

(a) Is triggered only after complete device destruction
(b) Uses condition monitoring data to predict failure before scheduled PM interval
(c) Never uses equipment data
(d) Replaces all calibration requirements

Solution: (b). PdM is data-driven — trends trigger intervention before failure. PM is calendar-based regardless of condition.

A5. Commissioning of a new anesthesia workstation is complete, but HTM records show O₂ analyzer reads 96% when connected to 100% O₂ source. Next step:

(a) Close commissioning — alarms work so it is fine
(b) Perform calibration/adjustment of O₂ analyzer before clinical handover
(c) Decommission immediately
(d) Skip calibration; train users to mentally add 4%

Solution: (b). Commissioning confirms system function; calibration corrects measurement error before handover. Clinical use with known FiO₂ error is a patient safety violation.

A6. The HTM Manager's reporting relationship should ideally be to:

(a) Individual nurse unit managers separately
(b) Hospital administration with authority over technical services cross-departmentally
(c) External vendor only
(d) No one — fully autonomous without accountability

Solution: (b). Central HTM reporting to administration ensures impartiality, standardization, and budget authority across clinical departments (WHO Guide 1).

A7. Total removal of equipment from a health facility due to technical and clinical obsolescence is:

(a) Calibration
(b) Decommissioning
(c) Shipment
(d) Inventory audit

Solution: (b) Decommissioning (mock Q18). Disposal follows decommissioning decision.

A8. Selecting proper disposal method for medical equipment requires:

(a) Government authority consultation only
(b) Manufacturer instructions only
(c) Local regulation only
(d) All of the above

Solution: (d) All are correct (mock Q19). Comprehensive compliance.

A9. A 120-bed hospital standardizes on one ventilator model across ICU and ED. Expected HTM benefit:

(a) Increased spare parts variety and training complexity
(b) Reduced training burden, consolidated spare parts, improved technician competence
(c) Elimination of all CM needs
(d) Exemption from PM scheduling

Solution: (b). Standardization reduces variety — lecture and WHO Guide 1 principle. CM and PM still required.

A10. Equipment availability KPI for critical ventilators over one month: total hours = 720; downtime = 36 hours. Availability is:

(a) 90%
(b) 95%
(c) 85%
(d) 50%

Solution: (b) 95%.

11.4 Short Answer Questions (10)

SA1. Define Healthcare Technology Management in one sentence.

Solution: HTM is an accountable, systematic approach to ensuring cost-effective, efficacious, safe, and appropriate technology is available to meet quality patient care demands throughout the equipment lifecycle (ECRI definition).

SA2. List the five management functions applied in HTM.

Solution: Planning, organizing, staffing, directing, controlling — applied to healthcare technology assets and services.

SA3. Distinguish medical device and medical equipment.

Solution: Medical device is any instrument/apparatus/software intended for medical purpose without primary pharmacological action. Medical equipment is the subset requiring calibration, maintenance, repair, user training, and decommissioning managed by clinical engineers — excluding implantable, disposable, and single-use devices.

SA4. Name four minimum data fields in an equipment inventory record.

Solution: Any four: asset ID, manufacturer/model, serial number, location, acquisition date, functional status, warranty end date, last/next PM date, maintenance responsibility.

SA5. List three activities in the HTM lifecycle after procurement.

Solution: Any three: installation, site preparation, commissioning, training, operation, PM, CM, calibration, decommissioning, disposal.

SA6. Why is competitive bidding required in public hospital procurement?

Solution: Ensures transparency, fairness, value for money, and accountability — prevents arbitrary official-only purchases; allows cost and technical comparison by tender evaluators committee.

SA7. Distinguish commissioning and calibration with one example each.

Solution: Commissioning: whole-system acceptance testing after installation — e.g., verify ventilator alarms and modes function. Calibration: measurement accuracy adjustment — e.g., verify/adjust delivered tidal volume and O₂ sensor against standard.

SA8. List three preventive maintenance activities and one activity that is NOT PM.

Solution: PM: functionality inspection, periodic cleaning, lubrication/mechanical integrity test. NOT PM: welding and major spare part replacement after breakdown (corrective maintenance).

SA9. What is a CMMS and what three functions does it perform?

Solution: Computerized Maintenance Management System — software integrating asset registry, PM scheduling, work order management, and commonly spare parts tracking, cost reporting, and availability KPIs.

SA10. List three criteria triggering equipment decommissioning.

Solution: Any three: repair cost exceeds replacement threshold; manufacturer end-of-support; safety/regulatory non-compliance; clinical obsolescence; repeated failures despite CM.

11.5 Scenario-Based Questions (10)

SC1. Procurement office orders 3 ventilators without HTM specification review. Units arrive but lack pediatric modes required by ICU. Identify the HTM failure and corrective action.

Solution: Failure: procurement bypassed needs assessment and specification — clinical requirements not translated to mandatory tender clauses. Corrective action: reject non-conforming units if contract allows; invoke specification compliance clause; establish mandatory HTM sign-off on all future specifications; conduct retrospective root cause with tender committee.

SC2. Inventory audit finds 12 ventilators registered but ward count shows 9 physical units. Three listed as functional in database are missing. Implications and actions?

Solution: Implications: ghost assets inflate availability KPIs; PM scheduled for missing units wastes labor; possible theft, undocumented transfer, or decommissioning not recorded. Actions: full physical audit; investigate discrepancies; update CMMS; strengthen asset tagging and transfer SOP; report loss per hospital policy.

SC3. New ICU beds installed without O₂ outlets. Ventilators commissioned using cylinders only. Which planning phases failed?

Solution: Site preparation and hospital engineering coordination failed — MGPS/outlet provision must precede equipment installation (Ch 9 overlap). Needs assessment should have included utility readiness. Corrective action: engineering retrofit outlets; interim cylinder protocol with safety limits; never repeat procurement without site checklist sign-off.

SC4. Vendor offers 5-year warranty but refuses local training. HTM Manager recommendation at contract negotiation?

Solution: Reject or counter — training is essential for safe operation; contract must include hands-on training for users and HTM staff per specification. Warranty without trained users increases operator-error risk and CM calls. Negotiate training as mandatory deliverable before handover payment release.

SC5. PM due on 8 defibrillators; only 5 completed on time. PM compliance rate and risk?

Solution: PM compliance = 5/8 = 62.5% — below typical 90% target. Risk: undetected battery/m capacitor degradation → failed shock during arrest; accreditation finding; increased CM. Action: prioritize overdue units within 48 h; investigate backlog cause (staff, parts); escalate to administration.

SC6. Radiotherapy department requests disposal of linear accelerator. Outline HTM disposal process.

Solution: (1) Decommission clinically and technically; (2) notify government authority (radiation protection agency, EFDA); (3) follow manufacturer decommissioning protocol for source; (4) licensed radioactive waste handler per local regulation; (5) inventory write-off; (6) CMMS closure; (7) document disposal certificate for audit.

SC7. Two hospitals in a region each employ full Level 4 imaging engineers with low workload. HTM organizational recommendation?

Solution: Collaborative/regional HTM network (WHO Guide 1 model) — share Level 4 specialist across facilities via referral arrangement; reduce duplication; maintain in-house Level 1–2 at each site. Negotiate joint venture or regional workshop with shared on-call rota.

SC8. Ventilator alarm silenced by nurse during high-pressure alarm without checking patient. Identify training and HTM system gaps.

Solution: Training gap: insufficient hands-on alarm response training — silencing without assessment is unsafe. System gaps: alarm management policy not enforced; no competency verification; possible alarm fatigue from false alarms needing CM on expiratory valve. Actions: refresher hands-on training; SOP on alarm response; HTM investigate false alarm root cause.

SC9. Finance approves equipment purchase but zero maintenance budget. Predict consequences in Year 2.

Solution: PM non-compliance → increased CM and downtime; warranty expiry without service contract; premature decommissioning; violated value equation (cost rises, benefit falls). Action: HTM must present TCO at procurement; WHO guideline — budget 8–12% of equipment value annually for maintenance support.

SC10. Tender committee wants to award ventilator contract to politically connected supplier with non-compliant bid. HTM Manager duty?

Solution: Document technical non-compliance formally in evaluation report; refuse to sign technical approval; cite competitive bidding law and patient safety; escalate to hospital legal/ethics committee. HTM Manager accountability is to specification compliance, not political pressure — professional duty to prevent unsafe procurement.

11.6 Calculation and Specification Problems (5)

CALC1. Hospital purchases ventilators totaling 4,800,000 ETB. Using 10% annual maintenance planning guideline, calculate minimum annual OPEX maintenance budget.

Given: Capital = 4,800,000 ETB; rate = 10%

Solution:

Answer: 480,000 ETB per year minimum planning allocation.

CALC2. CMMS reports ventilator downtime: January 12 h, February 8 h, March 4 h. Total ventilator-hours available per month = 720 h (one ventilator). Calculate Q1 availability.

Solution: Total downtime = 12 + 8 + 4 = 24 h Total available = 720 × 3 = 2160 h

Answer: approximately 98.9% Q1 availability.

CALC3. Repair quote for failed ventilator = 285,000 ETB. New equivalent unit = 450,000 ETB. Policy threshold: decommission if repair > 50% of replacement cost. Should HTM recommend repair or replacement?

Solution:

63.3% > 50% threshold → Recommend replacement/decommissioning over repair.

CALC4. PM schedule: ventilator quarterly PM takes 2 h each; annual calibration 4 h. Calculate total HTM labor hours per ventilator per year.

Solution: Quarterly PM = 4 × 2 h = 8 h; Annual calibration = 4 h

For fleet of 10 ventilators: 120 h/year total planned labor.

CALC5. Value comparison: Ventilator A — Benefit score 90, TCO 1,200,000 ETB. Ventilator B — Benefit score 75, TCO 600,000 ETB. Which has higher value index? (Use Value = Benefit / Cost)

Solution:

Answer: Ventilator B has higher value index despite lower absolute benefit — lower cost dominates in resource-limited setting. (Clinical minimum requirements must still be met — value ranking applies among compliant options.)
