NFPA and other certifying agencies have narrowed their philosophy for the inspection and certification of hospitals from an occupancy-based code to a Risk Based philosophy. This requires the hospital to identify potential dangers and faults in all their systems and have on hand a written policy to handle equipment maintenance and failures.
This plan is Risk Assessment.
Risk Management Part of the Higher Plan
“Risk management is a structured approach to managing uncertainty related to a threat, through a sequence of human activities including risk assessment, strategy development to manage risk and mitigation of risk using managerial resources.
The strategies could include transferring the risk, to another party, avoiding the risk, reducing the negative effect and accepting some or all of the consequences of a particular risk.” Nadeem Baig, HSE
Several surveyors are asking for or requiring Risk Assessment plans as part of their inspection routine. Other than the general principles outlined here, specific detailed guidelines for equipment, processes or buildings are still being formulated.
In general, risk assessment asks:
- What can go wrong?
- How bad could it be?
- What action should be taken?
- How often might it happen?
- How do we avoid this problem in the future?
6 Steps to Provide a Remedy for an Identified Risk
There are specific steps to carrying out a a risk assessment...
- Identify the hazards
- Identify who or what could be injured
- Evaluate the risk
- Evaluate probability
- Record and identify parties included
- Review and inform
Step 1: Research - Identify what failures or incidents can cause damage.
Step 2: Identify who or what could be injured or displaced by such a failure or event: patients, staff or the public.
Step 3: How critical would the damage be if the defect took place.
Step 4: How likely is this problem to happen?
Step 5: Create a remedy or procedure to work around the adverse event and identify the responsible parties.
Step 6: Review the corrective action plan with staff to make sure they understand and can fulfill their responsibilities in the event of a defect occurring.
The events you identify should be filtered through a grid like the one below that clarifies the importance and urgency of action to remedy the problem and value the risk of a bad outcome.

List Equipment to Prepare for Remedies
ASHE provides a spreadsheet to list equipment and areas of the hospital that are important to patient care and from there you can individually plan the remedies for failures that may occur at these sites.
NFPA, CMS and TJC require an inventory of equipment to be available during inspection and for medical gas purposes that would be the starting point of filling out the equipment grid from ASHE below.
Risk Assessment Form Example
Those hospitals using the Vitaleyez software should be able to get the inventory identification information directly from the program. (i.e. Asset description, manufacturer, model #, all historical inspection data).
Hospital Risk Assessment Defined by Risk to Patient
Risk based assessment assigns a value to each asset by their use and their potential to be harmful to the patients or staff. For example, an oxygen outlet in an emergency room would have the highest urgency while the outlet in the storeroom would have the lowest priority.
The hospital in conjunction with the inspecting company following NFPA guidelines would establish an urgency level to each device and then set an inspection and repair schedule for the assets based on the risk rating to patients rather than the date on the calendar.
Building System Categories Defined by Threat
The categories are broken down into harm to patients, staff and visitors.
1. Failure may cause death or serious injury
2. Failure limited to minor injuries
3. Failure may cause discomfort
4. No impact on patients or caregivers
Category 1 - The system must always be highly functional. An example in this category would be a medical gas system in an ICU.
Category 2 - A system failure would not involve risk to life. High dependability is expected in this category.
Category 3 - Failure would cause discomfort but not likely to cause injury.
Category 4 - Patients are not adversely affected.
All building system categories will be driven by ensuing the risk assessment procedures.
Maintenance Programs and Risk Assessment
The Joint Commission identifies the activities and frequencies for maintaining, inspecting, and testing for all operating components of utility systems.
Various maintenance strategies may be used to ensure reliable performance (for example, predictive maintenance, reliability-centered maintenance, interval-based inspections, corrective maintenance, or metered maintenance). Defined intervals may be based on criteria such as manufacturers’ recommendations, risk levels, and current organization experience.
According to Standard EC.02.04.01, the organization manages medical equipment risks. Also in agreement under the Elements of Performance for EC.02.04.01 A 2, the organization maintains either a written inventory of all medical equipment or a written inventory of selected equipment categorized by physical risk associated with use (including all life-support equipment) and equipment incident history.
The organization evaluates new types of equipment before initial use to determine whether they should be included in the inventory.
Alternative Equipment Maintenance Programs
TJC and CMS allow Alternative Equipment Maintenance programs (which deviate from the manufacturer’s suggested intervals) if the hospital can prove with historical and industry data that the alternative program will keep up equipment performance. These alternative programs must be supported by the Risk Assessment that has become the standard philosophy to assess hospitals.
“The Joint Commission standards are not prescriptive with regard to tasks and frequencies for piped medical gas and vacuum systems. In accordance with EC.02.05.09, for each piped medical gas and vacuum system, the source, distribution, inlets/outlets, and the alarms that protect the systems are to be maintained in a safe and reliable condition. These are considered high-risk utility systems.
In accordance with EC.02.05.01, the organization is to develop a maintenance strategy based upon manufacturer's recommendation or an alternative equipment maintenance (AEM) strategy. Issues such as system complexity, system age/condition, patient acuity, etc. are to be used to assess maintenance strategies.
NFPA 99 Appendix C can be used as a guide for establishing a maintenance strategy, but appendix material are not requirements unless adopted by a controlling authority. The survey process will evaluate the maintenance strategy assessment process for effectiveness, and validate that it has been properly implemented. [EC.02.05.09]
Release of TJC Elements of Performance
TJC-accredited hospitals, for example, now face an even more important reason for having an effective AEM-inclusion risk assessment process since the official 1-9-2017 release of TJC’s updated Elements of Performance. The broad utility system inspection, testing & maintenance (ITM) Standard EC.02.05.05 contains newly changed language concerning required utility ITM completion rates.
The impacts of the updated EP language issued on 1-9-2017 basically require:
In EC.02.05.05 EP-4: 100% on-time compliance for all High Risk utility system components, whether done through the Alternative Equipment Maintenance (AEM) program or done in accordance with manufacturer’s recommendations;
In EC.02.05.05 EP-5: 100% on-time compliance for all Infection Control utility system components, whether done through the AEM program or done in accordance with manufacturer’s recommendations;
In EC.02.05.05 EP-6: down to not less than 90% on-time compliance for other Non-High Risk components done through the AEM program only if the organization’s policy (presumed to be the utility systems equipment AEM Program policy) permits such deferral.
In other words, TJC accredited hospitals have some flexibility to mandated 100% on-time Inspection, Testing and Maintenance compliance only for their non-high-risk and non-infection control utility system components that are managed through an acceptable Alternative Equipment Maintenance Program.
Critical Factors to Consider When Evaluating Risks Associated With Equipment
Whether equipment is critical (TJC high-risk) equipment is one of the tests. It may even be the most important factor to consider, but it is not the only factor.
Within The State Operations Manual, Appendix A – Survey Protocol, Regulations and Interpretive Guidelines for Hospitals, A-0724 (Rev.); Interpretive Guidelines §482.41(c)(2), CMS states “Factors for a hospital to consider when evaluating the risks associated with a particular type of equipment include, but are not limited to:
- "How the equipment is used and the likely consequences of equipment failure or malfunction – would failure or malfunction of the equipment hospital-wide or in a particular setting be likely to cause harm to a patient or a staff person?”
- “How serious is the harm likely to be?”
- “How widespread is the harm likely to be?”
- “Information, if available, on the manufacturer’s equipment maintenance recommendations, including the rationale for the manufacturer’s recommendations;”
- Are they simple or complex?
- Are the manufacturer’s instructions and procedures available in the hospital, and if so can the hospital explain how and why it is modifying the manufacturer’s instructions?
- If the manufacturer’s instructions are not available in the hospital, how does the hospital assess whether the AEM uses appropriate maintenance strategies?
- How readily can the hospital validate the effectiveness of AEM methods for particular equipment? For example, can the hospital explain how it ensures there is no reduction in the quality of the performance of biomedical equipment subjected to alternate maintenance methods?”
- “The timely availability of alternate devices or backup systems in the event of equipment failure or malfunction”
- “Incident history of identical or very similar equipment”
CMS also stated “Generally multiple factors must be considered, since different types of equipment present different combinations of severity of potential harm and likelihood of failure. The hospital is expected to be able to demonstrate to a surveyor the factors it considered in its risk assessment for equipment placed in its AEM program.”
"Legacy computerized maintenance management systems (CMMS) generally do not adequately address these AEM inclusion risk assessment requirements with their original risk assessment programming. This situation appears to be because the newly required risk assessment factors are generally not the same as the more commonly-used factors that hospitals have used in past utility system risk assessments. A new risk assessment framework appears to be required to support AEM-inclusion decisions.”
Suggested CMS Checklist to Identify Risks and Their Protections and Remedies
For general hospitals performing anesthesia the risk level for medical gas equipment is always high as they sustain life and their interruption would likely cause death or serious harm to patients and perhaps other equipment, except in Category 3 or 4 facilities.
The default inspection and testing regime for medical gas equipment has been the Manufacturer’s suggested frequency. This usually means: annually for equipment like outlets, inlets, valves and alarms and quarterly for active source equipment like pumps and compressors and monthly for power changeover test systems.
Emergency Operations Planning
One other area that has gained current attention is emergency planning for larger scale shutdowns that will mean unusually large numbers of patients and damaged utility systems that will strain hospital normal operations.
Here are the suggested questions from one agency:
Emergency Operations Planning
- Life Supporting Equipment
- Oxygen, Medical Air, Vacuum (Potential Systems)
- How will you ensure systems are available during an emergency?
- What is the protocol for monitoring systems during the emergency?
- How will the Emergency Operations Plan be activated / deactivated?
- Will the plan meet the (96) Hour Sustainability Requirement?
- Staff must be educated on their specific duties and responsibilities.
- Some Options for Contingencies:
- Cylinders available for critical care patients
- Temporary back feed of all critical care portions of the system
- Portable vacuum systems available for critical care areas
- Suppliers temporary bulk oxygen trailer (Might not be practical)
As the various agencies collaborate on their reporting standards and methods the responsibility of the hospital to identify and maintain equipment is paramount.
The surveyors may well ask for an inventory of any or all equipment in the hospital including its maintenance history for at least the past two years. Any equipment failures that lead to serious harm to patients or staff are likely to be scrutinized as the process evolves. Detailed records of defective parts and adjustments need to be recorded as well.
An exhaustive study by John Collins, FASHE, HFDP done for ASHE Monograph determined the most frequently failing devices leading to patient injury were circuit boards. Assuming this holds true for your hospital, the piped medical gas system should be very reliable as the only circuit boards are in the source equipment control panels and alarm panels.
This could mean more scrutiny on the activation and calibration of alarm systems for medical gas. Motors and wear parts were far behind in terms of creating failures, but many of these potential failures can be anticipated with a regular preventive maintenance program.
The Vitaleyez program for medical gas systems provides the statistical history base for your risk assessment program. With the asset identity details and historical inspection data in hand, it is easier to fill in the grid above to satisfy the inspecting agencies.
