This blog reviews 15 tips for creating an effective CAPA form, including CAPA source, description of issue, investigation of root cause, and more.
The reason for creating a “great CAPA form” is to improve the effectiveness of your CAPA process. Anyone in your company could be assigned to a CAPA, but not everyone is a CAPA expert. Therefore, designing an effective CAPA form can reduce errors and improve effectiveness of the actions taken. You can also purchase our CAPA procedure and CAPA form which is compliant with ISO 13485:2016.
The CAPA procedure is a 4-page procedure which includes a CAPA form, and CAPA log. The procedure is compliant with ISO 13485:2016 and 21 CFR 820.100.
Provide adequate space in CAPA form
The most important feature of a CAPA form is to ensure that there is adequate space for writing a complete response for each section. Having adequate space is more important than the benefits of a shorter record.
Date your CAPA form was initiated
The date your CAPA form begins to be completed can be used to verify that there was not “undue delay” in the initiation of a CAPA in response to internal audit findings. The date of initiation is also used to calculate the due date for completing the investigation and providing a corrective/preventive action plan.
Include a cross-reference number in your CAPA form
This is typically a sequentially assigned CAPA log number. Ensure the number is prominent on all pages—just in case pages are separated.
The source of a CAPA is useful information when performing data analysis—especially for internal audits where the audit schedule should reflect results of previous audits. Examples of CAPA sources include:
- Complaints/Reportable Events
- Internal, Supplier and Third-Party Audits
- Service Work Orders
- Nonconforming Materials
- Management Reviews
Description of CAPA issue
I use the word “issue” instead of nonconformity, because you need a CAPA form that will work for potential nonconformities (i.e., – preventive actions), as well as nonconformities. Typically, the wording is identical to a customer complaint or an auditor’s wording, but the description of the issue identifies the symptoms observed. Specific references to records, locations, times, equipment, products and personnel involved may be important to the root cause investigation.
Investigator assigned / target due date for plan
In ISO 13485:2016, the only change to the requirements for corrective actions and preventive actions was the clarification that planning is required. Since this was always implied in the standard, your procedure should already comply with clauses 8.5.2 and 8.5.3 in the 2016 version of ISO 13485.
This section of your CAPA form should identify who is going to investigate the root cause of the issue and the date that a corrective/preventive action plan is needed. The FDA requires submitting a corrective action plan for all 483 observations within 15 business days, or it will result in an automatic Warning Letter. Most certification bodies require a plan within 30 days. Your target due date should be risk-based, unless there is a specific regulatory requirement. The date will also need to be based upon the date the issue was identified—not necessarily the date the CAPA was initiated.
Investigation of Root Cause
This section always reminds me of the story about the Ohno Circle. Every company asks if they can close a nonconformity during an audit, and the answer should always be “No.” You can correct a problem, but you cannot perform a root cause investigation and implement an effective corrective action during the same audit. You need to investigate the cause and the investigation documented. Some companies include a specific tool in this section, such as a “Fishbone Diagram.” This is also a mistake, because there are many root cause analysis tools and you need to select the best one for your specific situation. You might even need to use more than one tool.
Containment of nonconforming product
If the issue requires preventive action, there is nothing to contain. If the issue is specific to a procedure’s deficiency, there is also nothing to contain. If the issue requires corrective action, and nonconforming materials or product are involved, then you need to quarantine the affected items. If affected product has already left the company’s direct control (see 21 CFR 806.2(l) for a definition), then you have a potential recall. Regulators often look for “bracketing” or “bounding” of the upper and lower lot limits for an issue. Therefore, this section is where you document the rationale for why certain lots of product/materials are quarantined and other lots are not.
Fixing the immediate problem does not prevent recurrence, but regulators will verify that each occurrence of the issue identified during the investigation of root cause has been corrected. You need should verify that each of the nonconformities identified in the original finding and the investigation are addressed in this section of your CAPA form. For preventive actions, this section is not applicable.
Corrective Action Plan/Target Due Date for Implementation
These are the steps planned to prevent recurrence. If the plan changes, then it should be updated. There is no need to delete the old version of the plan, but the new version should clearly include a date when the plan was revised. For preventive actions, this section is not applicable. The target date of implementation should reflect the risk associated with the issue.
Preventive Action Plan/Target Due Date for Implementation
These are the steps planned to prevent occurrence of a nonconformity. If an issue occurred for one product, but not for others, the actions taken for other products can be preventive. In this case, both the corrective action plan and the preventive action plan sections should be completed. The target date of implementation should reflect the risk associated with the issue.
Corrective and Preventive Actions Implemented
This section details what specific actions were performed—both corrective and preventive actions can be documented here. The dates of completing actions should be documented and reasons for delays and overdue actions should be identified.
Plan for Verification of Effectiveness
I recommend filling this section in before the plan for corrective and preventive action is developed. This often helps the person developing the plan ensure that actions planned are adequate. Whenever possible, this should be quantitative, and it helps to identify a specific date for performing the effectiveness check.
Verification of Effectiveness
This section of your CAPA form is where you document verification of effectiveness. Specifically, what verification activities were performed in order to ensure that the corrective and preventive actions you implemented were effective. The date verification of effectiveness was performed should be documented, and if the actions were not effective, then a new CAPA should be referenced here.
Signature and Closure Date
It is important for someone to review, sign and date your CAPA form when it is completed. Often, regulators will review only closed records.
