1. Purpose
To establish a systematic procedure for the trending and evaluation of market complaints received for Active Pharmaceutical Ingredients (APIs), enabling early detection of recurring issues, identification of trends, and implementation of preventive actions.
2. Scope
This SOP applies to all market complaints received by the Quality Assurance Department related to APIs manufactured and distributed from the facility. It covers the collection, analysis,
trending, evaluation, and reporting of complaint data.
3. Responsibilities
- QA Documentation Cell: Collects and maintains all complaint data and initiates trending reports.
- QA Officer/Executive: Conducts data analysis and prepares graphical and statistical complaint trend reports.
- Functional Department Heads: Review complaint trends relevant to their departments and implement CAPA if needed.
- QA Head: Reviews and approves all trending evaluations, escalates critical issues to management, and ensures inclusion in the Management Review Meeting.
4. Accountability
The QA Head is accountable for ensuring that all complaints are trended and evaluated periodically and that risk-based actions are implemented to prevent recurrence.
5. Procedure
5.1 Data Collection
- QA shall maintain a centralized Market Complaint Register (Annexure-1) where all complaint data is recorded.
- Information captured shall include:
- Complaint number and date
- Product name and batch number
- Nature and category of complaint
- Confirmed/not confirmed status
- Closure status and date
5.2 Categorization of Complaints
- Each complaint shall be categorized into one of the following types:
- Quality Complaint: Assay failure, impurity deviation, contamination, OOT
- Packaging Complaint: Labeling error, sealing issue, barcode problems
- Delivery Complaint: Delay, temperature excursion, transport damage
- Documentation Complaint: COA error, missing BMR pages, regulatory query
- This categorization shall be maintained in the Complaint Trending Log (Annexure-2).
5.3 Trending Frequency and Parameters
- Trending shall be conducted:
- Quarterly – by product, complaint type, and customer
- Annually – consolidated trend report
- Parameters trended include:
- Total complaints received
- Confirmed complaints
- Repeat complaints by product or department
- Average closure time
- RCA classification (e.g., human error, equipment failure, supplier-related)
5.4 Trend Analysis
- Complaints shall be plotted using bar graphs or Pareto charts (Annexure-3).
- Trends shall be evaluated for:
- Significant increase in complaints
- Patterns indicating systemic failure
- Recurring issues from specific customers or regions
- If a trend is detected, a detailed investigation shall be initiated via a deviation/CAPA as per site SOP.
5.5 Reporting and Review
- Quarterly Complaint Trending Reports shall be compiled by QA and submitted to the QA Head.
- These reports shall be discussed in:
- Internal Quality Review Meetings
- Annual Product Quality Review (APQR)
- Management Review Meetings
- Summary metrics shall be shared with all relevant departments for awareness and preventive action planning.
5.6 Regulatory Reporting
- For critical trends or high-impact complaints, Regulatory Affairs shall be informed to evaluate if market action or agency communication is required.
5.7 CAPA and Continuous Improvement
- QA shall track all complaints leading to CAPA in the CAPA Tracker (Annexure-4).
- Actions from trending (e.g., training, SOP revision, supplier audit) shall be monitored for closure and effectiveness.
6. Abbreviations
- QA: Quality Assurance
- CAPA: Corrective and Preventive Action
- OOT: Out of Trend
- APQR: Annual Product Quality Review
