Medical equipment inventory and asset register

What a medical equipment inventory is

A medical equipment inventory is the complete, current list of a hospital's medical devices, with each item's identity, location, owner, status and service details. It matters because it is the basis for preventive maintenance, repairs, recalls and replacement budgets, and because national rules require hospitals to keep one and show it to inspectors on request.

The World Health Organization's Introduction to medical equipment inventory management (2011) stresses that the inventory must be updated continually and is the foundation for scheduling preventive maintenance, tracking repairs, acting on alerts and recalls, and budgeting. Its 2025 successor, Inventory and maintenance management information system for medical devices, adds standardised nomenclature, unique device identification and digital tools for traceability. A spreadsheet can hold a first inventory; keeping it true for thousands of moving devices is what a maintenance system is for.

One device, two registers

Most hospitals keep two lists of the same equipment and rarely reconcile them. Clinical engineering keeps the technical inventory regulators ask for: every active device regardless of value, with serial number, location and maintenance history. Finance keeps the fixed-asset register: items above a capitalisation threshold, with cost, useful life, depreciation and net book value. A 900-euro infusion pump may be on the first list and not the second; a building's medical gas plant may be on the second and missing from the first.

The fix is not one list for everyone but one record per device with fields that serve both. Give every device a single in-house asset number, carry it on the technical inventory and the fixed-asset register alike, and the two lists can be reconciled by number rather than argued over by description. The accounting questions of what to capitalise and how to treat major repairs are covered in our guide on maintenance and the balance sheet.

What regulators expect the inventory to hold

Inventory rules are national, but the fields overlap heavily. The main requirements, as of October 2026, are these.

• Germany, MPBetreibV 2025 section 14 (Bestandsverzeichnis): all active non-implantable devices per site, with name, type, lot or serial number, year of purchase, manufacturer, in-house ID if any, location and organisational assignment.
• Germany, section 13 (Medizinproduktebuch) for Anlage 1 and 2 devices: identification, briefing records, dates and results of safety, metrological and IT security checks, maintenance dates and who did them, malfunctions and incident reports, kept five years after decommissioning.
• France, Public Health Code R.5212-18: an up-to-date inventory with common and trade names, manufacturer, supplier, UDI or failing that lot or serial number, location and date of first entry into service, available to inspectors.
• EU MDR Article 27(9): health institutions store, preferably electronically, the UDI of class III implantable devices they supply or are supplied with.
• United States, CMS S&C 14-07: all facility and medical equipment, leased or owned, in an inventory with a maintenance record, with suggested fields of unique ID, manufacturer, model, serial number, description and location; low-risk items may be grouped.
• United Kingdom, MHRA Managing Medical Devices: records kept in one system wherever possible, with a unique identifier, purchase price, history, location, maintenance and repair details and end-of-life date.

A field template that serves both registers

The template below merges the regulatory fields with what finance and maintenance need. Mandatory fields are the ones without which a record should not be saved; the rest can be completed during the first audit.

• Identity (mandatory): in-house asset number, common nomenclature name, manufacturer, model, serial or lot number, UDI where available
• Location (mandatory): site, building, department, floor and room, plus the responsible person
• Status: in use, in store, on loan, under repair, out of service or disposed, with the date of each change
• Regulatory: risk class, whether it is life-support or critical equipment, and the national check regimes it falls under
• Maintenance: PPM schedule, service provider, contract and its end date, warranty start and end
• Finance: acquisition date, cost, funding source, cost centre, useful life, depreciation method, net book value
• Lifecycle: date of first use, acceptance test record, expected replacement year, disposal date and method
• Documents: instructions for use, acceptance report, service manual and certificates

Keeping the inventory true: updates and annual audits

The WHO describes three update points: initial data collection; every change, with new equipment entered before it is used, leased or long-term borrowed items included, and changes of location, status, software, firmware or service provider recorded; and an annual audit. Its maintenance overview also proposes an equipment location rate, the share of scheduled devices actually found during the period, as a measure of inventory accuracy.

Worked example: the inventory lists 2,400 devices. The annual audit finds 2,352 of them, a location rate of 2,352 / 2,400 = 98.0 percent. Of the 48 missing, 21 turn up later in stores or on loan to another ward and their locations are corrected; the remaining 27 are investigated and, if not found, written off through the disposal process with finance. The walk-round also finds 35 devices that were never listed; they are added, given asset numbers and scheduled, so the corrected inventory holds 2,400 - 27 + 35 = 2,408 devices.

Arrival: acceptance and commissioning

The cheapest moment to create an accurate record is the day a device arrives. An acceptance work order should check the delivery against the order, confirm accessories and documents, perform the initial electrical-safety test (IEC 62353 covers testing before equipment is put into service as well as after repair and at recurrent tests), record the serial number and software version, attach the instructions for use, set the warranty start date and create the PPM schedule. Only when the checklist is complete should the device be released to the ward.

This one step solves several later problems. Warranty claims depend on a known start date. The first PPM is due from a known commissioning date, which matters in Germany where the safety-check interval is counted from the month of commissioning. And clinical users receive a device that is already in the inventory, so the WHO rule of entering equipment before use is met by design.

Worked example: depreciation and total cost of ownership

A hospital buys an ultrasound system for 120,000 euros plus 4,000 euros of installation, so the capitalised cost is 124,000 euros. With a useful life of 8 years and a residual value of 4,000 euros, straight-line depreciation is (124,000 - 4,000) / 8 = 15,000 euros a year. Other methods, such as declining balance or units of production for devices whose wear follows use, change the pattern but not the total.

Depreciation is only part of what the device costs. Over 8 years the hospital pays 124,000 euros for purchase and installation, 63,000 euros for a service contract in years 2 to 8 (7 x 9,000 euros), 6,000 euros of parts outside the contract and 2,000 euros for disposal: a total cost of ownership of 195,000 euros, or 24,375 euros a year. Maintenance, at 69,000 euros, is about a third of the total, which is why capturing work-order cost per asset matters for the next purchase. For public hospitals reporting under IPSAS 45, each part with a cost significant to the whole item is depreciated separately (paragraph 41), so major components such as an imaging tube may need their own line.

Worked example: flagging equipment for replacement

Linking the inventory to maintenance history turns replacement planning from opinion into rules. An illustrative policy flags a device when its age exceeds its expected life, when repair cost in the last 12 months exceeds 40 percent of replacement value, or when its mean time between failures falls below 120 days. Each flag starts a review, not an automatic purchase; clinical need, spare-part availability and manufacturer support end dates complete the decision.

• Ultrasound A: 9 years old against an 8-year life; repairs 21,000 euros against a 110,000-euro replacement, 19.1 percent; flagged on age
• Infusion pump B: 5 years old; repairs 1,150 euros against a 2,400-euro replacement, 47.9 percent; flagged on repair cost
• Patient monitor C: 4 years old; 6 failures in 365 days, a mean time between failures of 365 / 6 = 60.8 days; flagged on reliability

Disposal, resale and record retention

Disposal closes both registers. Technically, the device is taken out of service, decontaminated, data-wiped where it stores patient data, and its records are kept: five years after decommissioning for the German medical device book and five years after the end of use for the French maintenance register. In France, a seller of a second-hand device on the regulated list must provide an attestation of regular maintenance with the register history attached, so a complete record supports resale value.

Financially, the gain or loss is the difference between proceeds and net book value. If the ultrasound above is sold after 6 years for 18,000 euros, accumulated depreciation is 6 x 15,000 = 90,000 euros and net book value is 34,000 euros, so the loss is 16,000 euros. The entry is: Dr Cash 18,000 / Dr Accumulated depreciation 90,000 / Dr Loss on disposal 16,000 / Cr Equipment at cost 124,000.

Keeping the register in Skyline Nexus ERP

In Skyline Nexus ERP, the Asset Management register holds each device with serial number, manufacturer, model and model number, barcode and QR code fields, department, floor and room, and the Components screen links parent and child assets, so an imaging system and its major parts can be recorded separately. Acquisitions go through Procurement with Pending Approvals. Depreciation offers Straight Line, Declining Balance, Sum of Years Digits and Units of Production, runs monthly and posts to the general ledger when Auto-post Depreciation Entries is switched on; acquisition, disposal, revaluation and impairment have their own postings. Reports include the Fixed Asset Register, Depreciation Schedule, Asset Valuation, Movement History, Disposal Report and Compliance Report.

On the maintenance side, Skyline Nexus CMMS work orders link to the asset. An Acceptance work order carries a default checklist and cannot be completed until it is 100 percent done, warranty claims record claimed, approved and recovered amounts, and work orders note whether the asset was under warranty when raised. Maintenance costs are captured per work order and reported by asset, department and cost centre, including Maintenance Costs in the Asset Financial Centre, while MTBF and asset lifecycle cost views support replacement reviews.
