| + | ====== The Basic Steps of Conducting a Healthcare FMEA ====== | ||
| + | - 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. | ||
