This plan describes post-market surveillance activities. This plan is a result of the processes described in SOP Post-Market Surveillance. The results of the execution of the PMS plan are described in the PMS report or the periodic safety update report (PSUR). This plan concerns PMS data related to Consectetur adipiscing elit sed do
.
PMS data is collected from various sources. The PMS plan shall address the collection and utilization of available information, in particular:
This information is collected and analyzed as a normal process according to SOP Clinical Evaluation, SOP Post-Market Surveillance, SOP Feedback and Complaint Management, SOP Vigilance, SOP Corrective and Preventive Actions, and SOP Risk Management. If data acquired through these processes is applicable to the PMS inputs and within the surveillance period, it shall be included in the PMS report without any additional data action required.
Vigilance data from the following sources are considered:
The following keywords can be used to identify vigilance data:
Ut enim ad minim veniam quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
Data from the complaints management system is considered for this section. Any information concerning serious incidents, including information from PSURs (as applicable), field safety corrective actions, records referring to unknown non-serious incidents and data on any undesirable side-effects, and information, including feedbacks and complaints, provided by users, distributors and importers determined to be relevant shall be included in a report of PMS data (PMSR or PSUR, as needed).
The number of complaints should be compared against the sales or install volume of the device in order to generate a complaint rate.
A summary of corrective and preventive actions for the device shall be provided in the report. Additionally, any field safety corrective actions on similar devices identified through vigilance searches or other data inputs should be considered as well.
Serious incidents identified during the surveillance period will be considered in the PMS or PSUR report. A summary of the incidents and the actions taken will be included.
Non-serious incidents and undesirable side effects will be summarized in the PMS or PSUR report. The summary will include the number of incidents and the nature of the incidents that were not already covered by the risk assessment.
It is required to report any statistically significant increase in the frequency or severity of incidents that could impact the benefit-risk analysis and pose risks to the health or safety of patients, users, or other individuals. This section outlines the methodology for trend analysis, with a specific focus on the Mann-Kendall test, tailored to the characteristics of the device and its market performance. Other statistical tests may be used if they are more appropriate for the data, including the Nelson Rules, a Weibull Analysis, a regression test, or a Neumann trend test.
The Mann-Kendall test is a non-parametric statistical test designed to identify trends in time series data, making it well-suited for post-market surveillance analysis. The PMSR or PSUR report will include the results of the Mann-Kendall test, which will be used to identify trends in the data.
The data used for the analysis will include complaint data and vigilance data collected over the surveillance period. The data will be ordered by time and the Mann-Kendall test will be used to identify trends in the data. Significance will be determined using a p-value of 0.05, or other values as appropriate for the data. A positive value indicates a positive (increasing) trend, a negative value indicates a negative (decreasing) trend, and a value near zero suggests no trend.
Should the trend analysis find that the estimated probability or severity of risks were too low, reporting will be performed as needed according to SOP Vigilance and SOP Corrective and Preventive Actions and the risk management file will be updated accordingly.
