The CMMS: Service History, Recalls, and Compliance and Performance Reports

Unit 3: Regulation, Accreditation, and the CMMS. Lesson 13 of 60 in CRES Academy.

The CMMS is the database of record for everything your department owns and everything you have done to it. If the repair is not in the system, as far as an inspector is concerned it did not happen.

What it holds

Inventory        every device by control number, model, serial number, location, risk class, interval
Work orders      who called, the symptom in their words, the finding, the fix, parts, labor, readings
PM schedule      what is due, what is overdue, completion rate by area and by technician
Parts and costs  what was used, what it cost, cumulative cost against replacement value
Service history  every visit on that device, vendor reports attached, so repeat failures show
Documents        manuals, physicist surveys, electrical safety results, recall notices

Using it on a job

Open or accept the work order before you start, so labor and downtime are real rather than reconstructed.
Record the symptom as the caller said it, not as you have already decided it is.
Document the finding, the parts, and the measurements with their tolerances, and attach the vendor report or the output test sheet.
Close the work order with the room's return-to-service time, because that is the number radiology and the payer care about.

A habit worth building: read the device's service history before you touch it. Three similar calls in a quarter is a pattern, and the pattern is often the answer.

Recalls and field notices

When a manufacturer field notice or an FDA recall arrives, the system is how you prove you handled it: search the inventory by model and serial range, list every affected device and its location, record the action taken on each one with a date, and keep the notice itself attached to those records. Devices in storage, loaners, and units at off-site clinics are the ones that get missed, which is why the search is done against the inventory and not from memory.

Compliance and performance reports

Compliance reports answer a surveyor: PM completion rate, overdue list with reasons, inspection history, electrical safety results, apparel inspection records.
Performance reports answer management: MTBF, the mean time between failures, per device and per model, plus downtime by room, cost of service against replacement value, and vendor response times. They are what a replacement request is argued from, and they only exist if work orders were closed honestly.

Why complete records are your defense

After an incident, the record is the only thing that speaks for you. A device with a full history showing scheduled maintenance completed, measurements inside tolerance, and the fault reported and acted on puts the technician and the hospital on solid ground. A device with a gap in its history leaves the gap to be explained by someone else later.

Exam tip: the computerized maintenance management system holds inventory, work orders, PM schedules, parts, costs, and service history. Recalls are handled by searching the inventory and documenting the action per device. Compliance reports show completion and overdue; performance reports show time between failures, downtime, and cost. Undocumented work does not exist.

Remember

The CMMS holds the inventory by control number with risk class and interval, every work order with symptom, finding, parts, labor, and readings, the PM due and overdue lists, costs, and the full service history with vendor reports; you open it before the job and close it with the return-to-service time; recalls and field notices are answered by searching the inventory and documenting the action on each device; and compliance reports prove completion and inspection history while performance reports give MTBF, downtime, and cost for management.

Deeper explanation

The system is the proof

Everything you do is invisible to a surveyor, a manager, and a lawyer except through the CMMS. That is not a bureaucratic complaint, it is the practical reality: the record is the work, as far as anyone outside the shop can tell. Technicians who understand that spend two extra minutes per work order and never have to reconstruct a year of history under pressure.

What it holds, and why each field exists

Data                 Fields that matter                        What it answers
Inventory            control number, model, serial number,     "show me your inventory" is
                     manufacturer, location, department,       the first request of every
                     risk class, PM interval, install date,    survey
                     replacement value
Work order           requester, date and time, symptom in      what happened, who did what,
                     their words, finding, action, parts,      and whether it is fixed
                     labor hours, downtime, readings with
                     tolerances, return-to-service time
PM schedule          due date, interval, completion date,      completion rate, overdue list,
                     technician, result                        and the reason for each
Parts and cost       parts used, cost, cumulative cost         repair or replace, and the
                     against replacement value                 budget argument
Service history      every visit on the device, vendor         is this a repeat failure
                     reports attached
Documents            manuals, physicist surveys, electrical    the evidence a surveyor
                     safety results, recall notices,           asks to see
                     acceptance tests

The work order, done properly

Open it before you start. Labor and downtime reconstructed at the end of the week are fiction, and downtime is the number radiology quotes to administration.
Record the symptom as reported. "Room 2 will not expose, started after a cleaning crew was in" is worth more than "no exposure," and it is often the whole diagnosis.
Read the service history before touching the machine. Three similar calls in a quarter is a pattern, and the pattern is usually the answer.
Document the finding separately from the action. "Rotor-ready interlock contact open, contact block corroded" plus "replaced contact block" is a usable history; "fixed rotor" is not.
Put the numbers in. The measured value, the tolerance it is judged against, and pass or fail. A value with no tolerance beside it proves nothing.
Attach the evidence: the vendor report, the output test sheet, the phantom image, the electrical safety printout.
Close it with the return-to-service time, and tell the department what works, what does not, and what to avoid.

Recalls and field notices

A notice arrives naming a model and a serial range. The system is how you prove you handled it.

Step   Action                                              Record left behind
1      Log the notice itself as a document                 the notice, with its date received
2      Search the inventory by model and serial range,      a list, generated rather than
       including storage, loaners, and off-site clinics     remembered
3      Open a work order per affected device                one trail per device
4      Perform the required action: update, inspect,        finding and action, dated, per device
       replace, or remove from service
5      Report completion to the manufacturer if the         acknowledgement filed with the notice
       notice asks for it
6      Close the notice only when every device on the       a closed notice with no open children
       list is closed or documented as not affected

The devices that get missed are the ones not in service: a unit in storage, a loaner, a spare detector. That is exactly why the search is run against the inventory and not from memory, and why the inventory's accuracy is the foundation of the whole program.

Compliance and performance reports

Report type   Contents                                     Audience and use
Compliance    PM completion rate, overdue list with         surveyors and accreditation: proves
              reasons, inspection history, electrical       the program is managed
              safety results, apparel inspections,
              recall closure
Performance   MTBF by device and by model, downtime by      management: replacement requests,
              room, cost of service against replacement     staffing, vendor negotiations,
              value, vendor response times                  service contract decisions

Both reports are only as good as the work orders beneath them. A shop that closes calls with "fixed" produces reports nobody can act on, and then loses the argument when a room needs replacing.

Why the record is your defense

After an incident, the device's history is the only thing that speaks for you, and it speaks in your absence. A full record showing maintenance completed on schedule, measurements inside tolerance, the fault reported, and the action taken puts you and the hospital on solid ground. A gap in the history gets filled in by somebody else's theory. Write for the reader who will open the record in two years with a lawyer beside them.

What to memorize

The system holds inventory, work orders, PM schedules, parts and costs, service history, and documents.
Open before you start, record the symptom as reported, separate finding from action, include the measured value and its tolerance, close with return-to-service time.
Recalls: log the notice, search the inventory by model and serial range, a work order per device, document the action, close only when every device is accounted for.
Compliance reports show completion and inspection history; performance reports show MTBF, downtime, and cost.
