Part of our complete guide to Hospital Asset Management: The Complete Guide.
Asset management in hospitals is the work of planning, tagging, locating, maintaining and retiring the equipment a hospital owns, from infusion pumps and ventilators to beds and IT devices. Its most visible payoff at the bedside comes when it is connected to the nurse call system, so that a patient's call tells the responding nurse where the nearest working device is.
Quick answer: A nurse call system integration connects the call event at the bedside to the hospital's asset management or RTLS platform, so the responding nurse is told where the nearest available infusion pump, wheelchair, or monitor is when the call fires. Modern nurse call systems (Ascom, Rauland, Hill-Rom, Philips, Schrack, Tunstall and others) publish events over HL7 v2, REST webhooks, or MQTT, which is what makes the integration possible. The work starts by confirming that your nurse call server can publish those events, because closed systems are the most common reason these projects stall.
This guide is for hospital IT directors, nursing heads, and biomedical engineers evaluating a nurse call system for a hospital, or trying to get more out of the one already installed. It covers what a nurse call system is and how it works, the types you will be quoted, how the integration with asset tracking software is built, which vendors support it, and what it costs in time and money.

If You Are Deciding Whether To Integrate Nurse Call
This section is for the CIO, director of clinical engineering, or nursing informatics lead who has to decide whether to connect the nurse call system to anything beyond phones. The decision usually comes in one of three forms: a nurse call replacement where the RFP asks for "integration capability", an RTLS purchase that needs a nurse call partner, or a nursing request to stop hunting for pumps. The budget sits with IT or facilities capital, and the risk sits with nursing.
What goes wrong, in our experience, is predictable: the nurse call vendor charges for an interface licence nobody budgeted; the event feed turns out to carry bed and priority but no call type, so equipment requests cannot be told apart; the asset register is less than half tagged, so the lookup returns the wrong device; and nurses get another app they will not open. Each of these is checkable in the first two weeks, before any build money is spent.
Work Out Your Own Return
Use your own nurse call log. Every input below is something your team can pull or measure.
Annual nurse time returned = equipment-request calls per day x seconds saved per call / 3,600 x loaded nurse hourly cost x 365
- Equipment-request calls per day: from the nurse call report, filtered by call type. If call type is not captured, that is your first finding.
- Seconds saved per call: time a sample of nurses spends finding the device today. As a starting default, the 2014 Richardson study measured a 54-second median search for items in an emergency department; equipment on another floor takes longer.
- Nurse hourly cost: the US Bureau of Labor Statistics gives a median registered nurse wage of $46.90 per hour (May 2025), before benefits.
Worked example (estimate, illustrative inputs): 400 equipment-request calls a day x 54 seconds = 6.0 nurse hours a day. 6.0 x $46.90 = about $281 a day, or about $102,700 a year of nurse time returned to patients. This is time, not cash saved, and it excludes rental and replacement spend on devices that cannot be found. Replace each input with your own numbers.
How We Do It
We start from the event feed, not the dashboard. In week one we take a sample export from the nurse call server or middleware and check that each event carries room, bed, call type and timestamps. We map call types to equipment classes with the charge nurses, because "staff assist" means different things on different units. We put an interface engine (usually Mirth Connect) between the nurse call system and the asset register, so a vendor change later means rewriting one channel. And we test against the hospital's real floor plan, because "nearest" across a building link or a locked unit is often wrong on a simple distance map.
The pitfalls we plan for: interface licences from the nurse call vendor, call types that were never configured, untagged equipment, and duplicate alerts when RTLS also clears calls. Our timeline for a 500-bed hospital is in the deployment section below.

What Asset Management In Hospitals Covers
Asset tracking answers one operational question: where is this device right now. Asset management is wider. It covers the full life of each asset: purchase, tagging, deployment, preventive maintenance, utilization, and retirement or replacement. Hospital teams usually split assets into three groups, each with its own owners and tools:
- Clinical and biomedical equipment. Infusion pumps, monitors, ventilators, defibrillators, wheelchairs. Owned by clinical engineering (biomed), maintained in a CMMS.
- Facilities and plant. HVAC, generators, medical gas, beds and furniture. Owned by facilities.
- IT and connected devices. Workstations, phones, network gear and networked medical devices. Owned by IT, often in an ITSM or CMDB tool.
Most hospitals start with high-value mobile equipment that goes missing often, such as IV pumps, ventilators and defibrillators, because that is where search time and rental spend pile up. Location data usually comes from barcode or RFID scans, BLE tags, or a real-time location system (RTLS) built on the hospital Wi-Fi.
The reason asset management matters to nursing is simple: a device that cannot be found, or is found overdue for maintenance, delays care. Linking the asset register to the nurse call system turns a call into a direct lookup, which is the rest of this guide.
| Question | Asset tracking | Asset management |
|---|---|---|
| Where is the nearest free pump? | Yes | Yes |
| Is it due for preventive maintenance? | No | Yes |
| Do we own too many or too few of this model? | No | Yes, from utilization data |
| When should it be replaced? | No | Yes, from lifecycle and repair history |
What Is A Nurse Call System And How Does It Work?
A nurse call system is the bedside-to-nurse-station alerting network in a hospital. The patient presses a pendant or pull-cord; the call registers on a corridor dome light, a nurse station console, and increasingly on a nurse's mobile handset. The nurse acknowledges, attends, and cancels the call at the bedside. Every event is time-stamped, which is what makes response time measurable.
The basic components are the same across vendors:
- Call points. Patient handsets, pull-cords in bathrooms, code-blue buttons in ICU and OT, staff-assist buttons.
- Room controller and dome light. Local logic and the corridor indicator, colour-coded by call priority.
- Nurse station console. Displays active calls by bed and priority; may be a physical panel or a screen.
- Server and middleware. Routes calls to staff, escalates unanswered calls, logs everything, and exposes the event feed that other systems consume.
- Mobile delivery. DECT handsets, Wi-Fi phones, or smartphone apps that receive the call wherever the nurse is.
Types Of Nurse Call Systems Hospitals Are Quoted
| Type | How It Connects | Where It Fits | Integration Readiness |
|---|---|---|---|
| Wired nurse call bell system | Dedicated cabling to a panel per ward | Older buildings, nursing homes, budget wards | Low: usually no event export |
| Wireless nurse call system | RF or Wi-Fi call points to a gateway | Retrofits, day-care, OPD, older wards | Medium: gateway may expose events |
| IP / networked nurse call | Ethernet or PoE room controllers on the hospital LAN | New builds, tier-1 hospitals, ICU/OT | High: HL7, REST, or MQTT event feed |
| Integrated clinical communication platform | Nurse call plus middleware plus mobile app | Large multi-specialty and teaching hospitals | High: built for third-party integration |
The integration described below needs the third or fourth type, or a wireless system whose gateway can publish events. If the hospital is still on a wired bell system, the integration is a reason to upgrade, not something to bolt on.
Where The Time Goes
For any call that needs equipment (an infusion pump, a wheelchair, a portable suction unit, a vital signs monitor) the nurse first has to find it. A peer-reviewed observation of 74 emergency department nurses (Richardson et al., Journal of Nursing Administration, 2014) found nurses leaving the patient room about eight times per eight-hour shift to fetch items, with a median search of 54 seconds before the unit changed its storage. When the asset register does not match reality, that search grows.
Integrating the nurse call system with asset management software collapses that delay. When the call event fires, the asset platform returns the nearest available asset of the right type, its location, and the path to it. The responding nurse goes directly to the equipment. The integration removes the lookup step.
What The Nurse Call Integration Actually Does
The integration is event-driven. When a nurse call event of a relevant type fires (call types are configurable: bedside emergency, equipment request, transfer assist), the asset management platform receives the event with the patient location, equipment type required, and priority. The platform queries its real-time asset location index and returns the nearest available asset.
"Available" means: tagged, currently in service, not checked out elsewhere, not under maintenance. The platform ranks candidates by distance on the floor plan, preferring the same floor and unit, to pick the nearest match. The answer is pushed to whichever screen the responding nurse is looking at.
The same event feed also supports:
- Response-time reporting. Call-to-acknowledge and call-to-cancel by ward, shift, and call type, which is the evidence NABH surveyors ask for.
- Equipment demand mapping. Which wards generate the most equipment-request calls, and for what, so biomed can rebalance the fleet.
- Escalation to RTLS. If the nearest asset is BLE-tagged, the nurse gets a live position rather than a last-known zone. See how IoT sensors and RTLS extend hospital asset tracking.
Nurse Call Systems That Support The Integration
The architecture is vendor-neutral. What matters is whether the nurse call server exposes an event feed. The systems and layers we see most often:
- Ascom Telligence: clinical communication platform with a published integration layer (Unite) that RTLS vendors such as Midmark connect to.
- Rauland Responder: Responder 5 and Responder Enterprise, with a Vendor Integration Partner program and HL7 and API support.
- Hill-Rom (Baxter) NaviCare / Voalte: common in academic and teaching hospitals, native mobile delivery.
- Alarm and messaging middleware (Spok, Connexall, PerfectServe, Vocera): often already receives nurse call events over WCTP, TAP or SIP, and can be the easiest place to tap the feed.
- Schrack Seconet, Tunstall, Ackermann, Legrand: frequently specified in Indian new-build projects; integration capability varies by generation, so check the server model before assuming an event feed exists.
- Indian OEM wireless systems (Forbix and similar): usually a closed gateway; ask the vendor for an MQTT or REST export before signing.

Two recent vendor developments show where the market is heading. Baxter completed its acquisition of Hillrom, which owns the Voalte communication platform and its nurse call line, in December 2021, and Hillrom has announced a locating system for staff and asset tracking that integrates with its own nurse call. In May 2026 Sonitor announced that its RTLS platform joined Rauland's Vendor Integration Partner program, describing secure API and HL7 integration with Responder, automatic call clearing when a caregiver enters the room, and duress alerts from staff badges. RTLS and nurse call vendors now treat location as a standard input to nurse call, which is what makes the asset lookup practical.
Integration Architecture: The 4 Layers
Layer 1: Event Source
The nurse call system publishes events on its native protocol: HL7 v2 messaging for older systems, REST webhooks for modern ones, MQTT for event-driven deployments.
Layer 2: Event Broker
An MQTT broker or webhook handler ingests events in real time. The broker normalises the event format across nurse call vendors so the asset platform sees a single schema. This is also where the hospital's integration engine (Mirth Connect is common) sits if HL7 v2 is in play.
Layer 3: Asset Management Lookup
The asset platform (Assetly, or the register you already run) receives the normalised event, reads the patient location and required equipment type, and queries its asset location index. We build this lookup as a small service in front of the register so it works with whichever asset system the hospital owns.
Layer 4: Notification Delivery
The asset location is surfaced on the responding nurse's mobile device, the nurse station screen, or back into the nurse call system's own UI. The exact delivery point depends on the hospital's clinical workflow. Pushing it back into the nurse call handset is usually best, because it means no new app for nursing staff.
Nurse Call And RTLS: When You Need Both
Asset management gives you the register and last-known location of every tagged device. RTLS (real-time location, usually BLE or Wi-Fi) gives you live position. For most equipment-request calls, last-known zone from RFID portals is enough to send the nurse to the right room. For ICU ventilators, crash carts, and transport monitors, hospitals add BLE so the nurse call integration returns a live position. The RFID vs barcode comparison covers when each tracking layer earns its cost.
What It Means For NABH Hospitals In India
NABH assessors look for evidence that patient calls are attended within a defined time and that critical equipment is available when needed. A nurse call system with an integrated asset lookup produces both pieces of evidence from the same log: call-to-response time by ward, and time-to-equipment for equipment-request calls. Indian hospitals also tend to have mixed estates, a new IP nurse call block next to a 15-year-old wired bell system, so the integration usually starts in the new block and becomes the business case for upgrading the rest.
What It Means For US Hospitals
In the US the same log answers two recurring questions from surveyors and quality teams: how quickly patient calls are answered, and whether critical equipment is maintained and available. The Joint Commission expects documented preventive maintenance for medical equipment, and the asset record that drives the nurse call lookup is the same record that holds that maintenance history. Keeping one register for both avoids the common split where biomed, facilities and IT each hold a different version of the truth.
Deployment Timeline And What It Costs
The plan we work to for a 500-bed hospital, once the event feed is confirmed:
- Week 1-2: Architecture design, event schema review with the nurse call vendor. Confirm the server exposes events; this is where closed systems get found out.
- Week 3-4: Test environment integration, end-to-end event flow validation.
- Week 5-6: Pilot in 2 departments. Measure baseline vs integrated response time.
- Week 7-12: Phased roll-out across remaining departments.
Cost has two parts. The integration itself is a software project measured in weeks of engineering plus any vendor API licence the nurse call OEM charges. The larger line is asset tagging: the integration is only as good as the share of mobile equipment that is tagged, so hospitals that have not yet deployed asset tracking budget for that first. The nurse call integration can run in parallel with tagging.
Key Takeaways
- A nurse call integration with asset management removes the equipment search from equipment-request calls; measure your own baseline before and after.
- The architecture is event-driven: nurse call event triggers an asset platform lookup, and the answer goes to the responding nurse.
- It needs an IP or integration-ready nurse call system; wired bell systems have no event feed.
- Largest gains are on mobile equipment requests: infusion pumps, wheelchairs, vital signs monitors.
- Ascom, Rauland and Hillrom publish integration interfaces in current generations; for Schrack, Tunstall and others, check the server model.
- Our plan for a 500-bed hospital is 8-12 weeks once the event feed is confirmed, and the same log gives response-time evidence for NABH or Joint Commission reviews.
Frequently Asked Questions
What is asset management in hospitals?
It is the planning, tracking, maintenance and retirement of a hospital's physical equipment across clinical, facilities and IT assets, with one record per device that shows where it is, whether it is in service, and when it is due for maintenance.
What is hospital nurse call integration?
It connects nurse call events to other systems, such as RTLS, staff phones, the EHR or asset management, usually over HL7 v2, REST webhooks or MQTT, so the right person gets the call with the context needed to act on it.
How does a nurse call system in a hospital work?
The patient presses a call point, the call shows on the corridor light, the nurse station and the nurse's handset, and the nurse acknowledges and cancels it at the bedside. Each step is time-stamped, which is what makes response time measurable.
Which nurse call systems support integration?
IP-based systems and clinical communication platforms from vendors such as Ascom, Rauland and Hillrom expose event feeds. Older wired bell systems usually do not, so check the server model before planning the work.
How much does a nurse call integration cost?
Two lines: engineering weeks for the interface and lookup, and any interface licence the nurse call vendor charges. Asset tagging is usually the larger cost if the hospital has not tagged its mobile equipment yet.
Will it work with our nurse call vendor?
If the server or middleware can send events over HL7 v2, WCTP, TAP, SIP, REST or MQTT, yes. The assessment confirms this from a real event sample.
Do nurses need a new app?
No. We push the result to the handset or console they already use where the vendor allows it.
Do we need RTLS for nurse call integration?
No. Last-known zone from RFID or barcode scans is enough for most equipment requests. Add BLE or other live location for critical mobile equipment such as ventilators and crash carts.
