In conducting a healthcare FMEA the basic steps are:
- Identify the process to be examined.
- Assign FMEA team members, team leader
and team facilitator.
- Explain the methodology to the team.
- Develop either a flowchart or detailed process
flow (outline format) of the process under analysis.
All steps in the process should be included.
- Designate which of the steps in the process
constitute "Functions."
- Determine which Functions represent potential
"Failure Modes" or points of potential
failure.
- Determine the worst potential adverse consequence
or "Effect" of each of the Failure
Modes.
- Determine the "Contributory Factors"
for each Failure Mode. A One or more Root Cause
Analyses may be necessary to complete this step.
Note that we advocate the use of the term "Contributory
Factor" rather than "Cause."
- Identify any "Controls" in the process.
Controls are components of the process which
(a) reduce the likelihood of a Contributory
Factor or a Failure Mode, (b) reduce the severity
of an Effect, or (c) detect the occurrence of
a Failure Mode or Contributory Factor before
it leads to the adverse outcome (Effect).
- Rate the Severity of each Effect (usually
on a scale of 1-10, with 10 being the most severe).
The impact of Controls that ameliorate the severity
of an Effect are reflected in this rating as
well.
- Rate the Occurrence (likelihood) of each Contributory
Factor (usually on a scale of 1-10, with 10
being the most frequent, or "certain to
occur"). The impact of Controls that reduce
the likelihood of occurrence of a Failure Mode
or Contributory Factor are reflected in this
rating as well.
- Rate the effectiveness of each "Detection
Control (usually on a scale of 1-10, with 10
being the lack of a Detection Control, or the
presence of a wholly ineffective one, and 1
being a 100% flawless detection system).
- Multiply the three ratings by one another
for each Contributory Factor and the corresponding
Effect and Detection Controls. The range of
these products will be from 1 to 1,000. The
resultant number is the Risk Priority number
(RPN) for that Contributory Factor.
- Rank-order the Contributory Factors according
to the Risk Priority Numbers.
- Use a Pareto Chart with the traditional 80%
rule to determine which contributory Factors
should be addressed first.
- Add to the above listing ALL Contributory
Factors which result in an Effect with Severity
of 10, irrelevant of RPN.
- Develop a plan addressing how the selected
Contributory Factors will be addressed, by whom,
when, how the improvement will be assessed,
etc.
- Continue the improvement process.
