Introduction to HFMEA

When a medical mistake results in a tragedy, the media prosecutes the healthcare community in the public forum. Trust in the healthcare system is eroded with the publication of these events. The safety of healthcare is of critical concern for all of us. We expect flawless execution when it comes to our healthcare needs. Techniques have been identified by The Joint Commission (TJC) to assure quality and reduce variation in the services provided. One of these techniques is Healthcare Failure Mode and Effects Analysis (HFMEA).

What is HFMEA

Healthcare Failure Mode and Effects Analysis (HFMEA) is a process used to identify potential failures and their causes before future services are provided. HFMEA can also provide opportunities to improve current services. Patient safety is ultimately the goal of the HFMEA Process.

Healthcare FMEA is a prospective assessment that identifies and improves steps in a process and reasonably ensures a safe and clinically desirable outcome. HFMEA is a systematic approach used to identify and mitigate risks which could potentially result in patient tragedy.

Why Perform HFMEA

Accident prevention has not been a major focus of healthcare facilities. Basically, hospitals have used common sense and experience as the primary way to identify problems. A prevailing belief also exists that healthcare providers perform faultlessly.

As is true for all hazard analysis approaches, risk is the substitute for failure on new and changed processes. It is good practice to identify risks on a process as early as possible. Early risk identification provides the greatest opportunity for verified mitigation prior to procedure use.

The Healthcare FMEA is applied when:

  • A new process, function or service with an associated hazard has not yet been implemented
  • A current process, function or service with modifications / changes due to past failure or sentinel events
  • A current process, function or service being used in a new or similar location

The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) requires the following:

  • Leadership ensures a proactive environment and program for identifying risks to patient safety
  • Reduction in Sentinel Events and medical / healthcare errors through Healthcare FMEA process
  • Identify high risk processes and select one process annually
  • Identify Failure Modes / Effects of Failure and conduct Root Cause Analysis on the items with highest severity
  • Redesign the process to mitigate the risks and/or protect the patient from the effects of the failure
  • Test to verify effectiveness of the process changes
  • Implement a strategy for maintaining effectiveness of the new process

How to Perform HFMEA

There are 5 steps required to complete Healthcare Failure Mode and Effects Analysis. The 5 steps are:

  1. Define the Topic
    • Scope the project with a clear definition of the process selected
  2. Assemble a Cross Functional Team
    • Team must be multidisciplinary
  3. Describe the Process
    • Create a Process Flow Chart or Diagram
    • Select a portion of the Process Flow Chart to be the focus (if complex process)
  4. Conduct the Healthcare FMEA
    • Follow the Three Path Model / Vertical Approach
  5. Determine Actions and Outcome Measures
    • Closure of the issue is expected

The following process reflects the Healthcare FMEA form and the Quality-One approach used in efficiently completing the analysis.

HFMEA Section 1 (Quality-One Path 1)

Failure Mode

The Failure Mode is the opposite of what the process is supposed to do or requirements not being achieved. One approach to determine Failure Modes is to review the requirement of the step being analyzed and list the Failure Modes in the context of what is expected for the process using:

  • Full Failure
  • Partial Failure
  • Intermittent Failure
  • Degraded Failure
  • Unintentional Failure

Effects of Failure

The Effects of a Failure Mode on multiple customers are listed in this column. Many Effects could be possible for any one Failure Mode. All Effects of Failure should appear in the same cell or grouped next to the corresponding Failure Mode.

Severity

The Severity of each effect is selected based on the impact / danger to the patient. Severity categories are as follows:

  • Catastrophic Event (9-10 in traditional FMEA). Examples may include: Patient death or major loss of physiological function, wrong surgery, wrong patient, wrong body part removed, infant abduction or improper discharge, death to visitor / hospital staff (or hospitalization of 3 or more staff), equipment damage of $250,000+ or fire.
  • Major Event (7-8 in traditional FMEA). Examples may include: Patient has permanent loss of bodily function, disfigurement, additional surgery required, increased stay for 3 or more patients, visitors or staff are hospitalized or equipment damage of $100,000.
  • Moderate Event (4-6 in traditional FMEA). Examples may include: Patient has increased length of stay, visitors may have to be evaluated / treated, staff may have lost time or restricted duty or equipment damage of $10,000 – $100,000.
  • Minor Event (Less than 4 in traditional FMEA). Examples may include: No patient injury or increased length of stay, visitors are evaluated but refuse treatment, staff receives first aid or equipment damage of less than $10,000 without any adverse impact on patients.

Actions may be identified to potentially change the direction on any Failure Mode with a related Catastrophic Effect. If a Recommended Action is identified, it should be placed in the Recommended Actions Column of the HFMEA.

HFMEA Section 2 (Quality-One Path 2)

Potential Causes/Mechanisms of Failure Mode

Potential Causes are then defined for each Failure Mode. The causes should be determined at the physics level. Use of words like bad, poor, defective or failed should be avoided as they do not define the cause with enough detail to make risk calculations for mitigation. Examples of Potential Causes are:

  • Wrong medicine administered
  • Incorrect material applied
  • Instructions not clear
  • Error by lapse
  • Missed steps in a procedure
  • Mistakes due to excessive pressure or lack of time

Probability

The Probability Ranking is an estimate based on known or lack of data. Probability categories are listed below:

  • Frequent (7-10 in traditional FMEA): Likely to occur immediately or within a short period of time (multiple times per year)
  • Occasional (5-6 in traditional FMEA): Probable (several times in 1-2 years)
  • Uncommon (3-4 in traditional FMEA): Possible (2-5 years)
  • Remote (1-2 in traditional FMEA): Unlikely (5-30 years)

A Scoring Matrix is commonly used to identify the criticality or Hazard Score. The hazard score is entered into the HFMEA form. Generally, the higher the Hazard Score, the greater risk to patient safety.

Actions may be directed against potential causes which have a high probability and / or Hazard Score. Special attention must be placed on items with Catastrophic Severity.

HFMEA Section 3 (Quality-One Path 3)

Decision Tree Analysis

The Decision Tree is utilized to determine if the failure is single point or multi point. Single point failure is more common as the probability of a single event is much greater than one where two or more individual causes are present simultaneously. The principle of Occam’s Razor is applied in these cases.

In Section 3, the Healthcare FMEA reviews:

Single Point Weakness

As described above, single point failures will happen more frequently than multi-point failures. Simple probability dictates actions would be expected against single point failures.

Existing Control Measure

If a control currently exists, a reference to that control is expected. Effectiveness of the control is also considered.

Detectability

If a control measure exists, an evaluation of the measure for effectiveness is discussed. At times a detection measure is so obvious, a formal control may not be necessary. If an action would improve detectability then the action is entered into the Actions column on the HFMEA form.

Proceed

A decision to proceed is expected. If the risk is low, the analysis may stop at this point. Rationale must follow the expectations of the hazard analysis.

HFMEA Section 4

In Section 4 of the Healthcare FMEA, the action type is selected. The choices are:

  • Eliminate: Error proofing and probability reduction are applied by identifying the actions which make it not possible for the error and failure mode to occur.
  • Control: This action type will identify the error and make it known that a control measure is required or an automatic control is applied to catch the error before the event can be experienced.
  • Accept: Inherent risks may be very low or the control for the error is currently acceptable. Any action taken would not be commensurate with the impact on the patient verses the cost to complete.

HFMEA Section 5

In Section 5 of the Healthcare FMEA, actions are reviewed and next-steps are determined.

Recommended Actions

All potential improvements are placed in the Recommended Actions column on the HFMEA. Completed actions are the purpose of HFMEA. Actions must be detailed enough to be understood if transferred to a risk register or actions list. Actions are directed against one of the rankings previously assigned. The objectives are as follows:

  • Eliminate Failure Mode Severity
  • Improve Probability (lower occurrence) on causes by Error Proofing, Reducing Variation or Mistake Proofing
  • Improve Detectability
  • Explain the rationale that exists as to why an action is not necessary

A measurable outcome must be selected to evaluate effectiveness of the action.

Person Responsible and Management Concurrence

Enter the name of the responsible person and the manager who concurs with the action. This allows the team and management to review the HFMEA progress at elimination of errors and / or improved controls at implementation. A review process is recommended until each action has been successfully closed. When an action has proven not to be as effective as desired, a new action may be necessary to mitigate the risk.
