Healthcare Failure Mode and Effect Analysis is a way for a team to find out how a care process could fail before a patient is harmed. Instead of waiting for an incident, the team maps the process, lists what could go wrong at each step, scores each hazard, and decides which ones need action.
This guide walks through the five steps of the method developed by the VA National Center for Patient Safety, shows how the scoring and decision tree work, and applies them to a weight-based medication example. The scoring scales and thresholds described are commonly used; follow your organization's own policy.
Before You Start
Why Proactive Risk Assessment Matters
Learn Before Anyone Is Harmed
Incident reviews look backward. HFMEA looks at how a process could fail so a team can fix it first.
Prioritizes Scarce Attention
A process may have dozens of possible failures. Scoring them shows the few that deserve action now.
Reveals Single Points of Failure
The decision tree asks whether one failure alone can cause harm, which exposes places where no other safeguard exists.
Builds a Team View of the Process
Mapping the real process with the people who work it often finds workarounds and handoffs nobody had written down.
What HFMEA Is
Healthcare Failure Mode and Effect Analysis (HFMEA) was developed by the U.S. Department of Veterans Affairs National Center for Patient Safety. It blends FMEA from engineering with hazard analysis and root cause analysis ideas, and it is designed for care processes where people, equipment, and information meet. The method is described by DeRosier and colleagues in the Joint Commission Journal on Quality Improvement (2002).
Accreditation and regulatory bodies, such as The Joint Commission in the United States, expect hospitals to carry out proactive risk assessments of high-risk processes. Check the current standard text that applies to your organization for what it requires, since expectations change and differ by country.
The Five Steps
| Step | What the team does | Output |
|---|---|---|
| 1. Define the topic | Pick a specific high-risk process and write the scope. | A clear problem and scope statement. |
| 2. Assemble the team | Include people who do the work, a subject expert, and an advisor who is not involved in the process. | A multidisciplinary team with a facilitator. |
| 3. Describe the process | Flowchart the process as it is actually done, number the steps, and label subprocesses. | A numbered flowchart. |
| 4. Analyze hazards | List failure modes and causes, score severity and probability, and apply the decision tree. | A scored list with proceed or stop decisions. |
| 5. Actions and outcome measures | For each proceed item, choose an action (eliminate, control, or accept), assign an owner, and define how success will be measured. | An action plan with measures. |
Scoring Hazards
Each failure mode receives a severity rating and a probability rating, each from 1 to 4. The hazard score is their product, from 1 to 16.
| Rating | Severity | Probability |
|---|---|---|
| 4 | Catastrophic: death or major permanent harm | Frequent: may happen several times in a year |
| 3 | Major: permanent loss of function or additional intervention | Occasional: may happen once in 1–2 years |
| 2 | Moderate: increased length of stay or level of care | Uncommon: may happen once in 2–5 years |
| 1 | Minor: no injury or need for extra care | Remote: may happen once in 5–30 years |
A score of 8 or more is the usual threshold for sending a failure mode to the decision tree. It is a convention; organizations may set their own, and lower-scoring single point weaknesses are often reviewed anyway.
The decision tree, simplified
- Is it a single point weakness? If one failure at this step can cause the harm with nothing else to stop it, proceed to action.
- If not, does an effective control already exist? If yes, document it and stop.
- If not, is the failure easily detected before it reaches the patient? If yes, stop. If no, proceed to action.
Worked Example: Pediatric Weight-Based Dosing
A hospital team analyzes how a weight-based medication moves from order to discharge teaching. Five failure modes are scored. The values are illustrative.
| ID | Failure mode | Sev | Prob | Score | Decision |
|---|---|---|---|---|---|
| F1 | Weight entered in pounds instead of kilograms | 4 | 3 | 12 | Proceed: no effective control and hard to detect |
| F2 | Decimal point misread on strength | 3 | 2 | 6 | Below threshold |
| F3 | Wrong concentration drawn up from adjacent pockets | 4 | 2 | 8 | Proceed: single point weakness |
| F4 | Barcode scan skipped when scanner is slow | 3 | 3 | 9 | Proceed: no effective control and hard to detect |
| F5 | Family not shown how to measure liquid dose | 2 | 3 | 6 | Below threshold |
Actions chosen. The team locks the order screen to kilograms and stops displaying pounds (eliminates F1). It separates the two concentrations into different cabinet locations with distinct tall-man labeling (controls F3). It fixes the slow scanner and tracks scan compliance weekly (controls F4). Each action gets an owner, a date, and an outcome measure: for example, "zero pound-entered weights in the monthly audit" and "barcode scan compliance at or above the unit target." F2 and F5 are logged and revisited at the next review rather than ignored.
Try this yourself with the HFMEA Hazard Scoring Tool. The same rows are pre-loaded. The HFMEA Worksheet Template carries the analysis through to the action plan.
HFMEA Compared With Manufacturing FMEA
| Aspect | Manufacturing FMEA | HFMEA |
|---|---|---|
| Scoring | Severity × Occurrence × Detection, giving an RPN | Severity × Probability, giving a hazard score, then a decision tree |
| Prioritization | Rank by RPN or action priority | Threshold plus decision tree with single point weaknesses |
| Typical subject | A design or manufacturing process | A care process with handoffs, people, and information |
| Team | Engineering-led | Multidisciplinary, including frontline staff and an outside advisor |
For the manufacturing method see the FMEA guide and the FMEA RPN and Action Priority Tool.
Self-Assessment Questions
- Did we map the process as it is actually done, with frontline staff in the room?
- Were severity and probability scored as a team, using defined scales?
- Did we look for single point weaknesses, not just high scores?
- Does every action have an owner, a date, and an outcome measure?
- Will we check whether the actions worked, and revisit the analysis after a process change?
Common Mistakes
Analyzing the Ideal Process
A flowchart of how the policy says the work is done misses the workarounds where failures really happen.
Blaming People
"Nurse forgets" is not a cause. Ask what in the design of the task makes that error likely and what would make it hard to make.
Choosing Weak Actions
Reminders and retraining are the weakest controls. Prefer forcing functions, standardization, and design changes that remove the failure.
Scoring Once and Filing It
An analysis that is not revisited when the process changes becomes false reassurance. Set a review date.
Patient Safety and HFMEA: Frequently Asked Questions
What does HFMEA stand for?
HFMEA stands for Healthcare Failure Mode and Effect Analysis. It is a team-based, proactive method developed by the U.S. Department of Veterans Affairs National Center for Patient Safety to identify how a care process could fail, score each failure, and decide which ones need action.
What is a single point weakness?
A single point weakness is a step where one failure, with no other failure needed, can cause harm to the patient and nothing else in the process would stop it. These are prioritized for action because no second safeguard exists.
Is a higher hazard score always worse than a single point weakness?
Not necessarily. A failure mode with a moderate score can still be a single point weakness with no backup safeguard, and many teams review those even below the score threshold. The score ranks hazards, and the decision tree helps decide what to do about them.
