Post-Market Surveillance Data Analysis

Post-Market Surveillance (PMS) for Medical Devices

Post-market surveillance or post-marketing surveillance (PMS) is a regulatory requirement for manufacturers of medical devices that need to collect and evaluate the experience obtained from the devices placed in a particular market.

For example, as a manufacturer of a closed-loop artificial pancreas system, your goal is to ensure that the medical device is safe and efficacious for your customers. However, a situation may arise wherein the device causes a major adverse event. In such a case, you need to find out what happened so that this adverse event does not repeat.

How do you achieve this?

There is a system of reporting to generate feedback on medical devices on the market. This is called post-market surveillance.

In this article, you’ll learn:

What is Post Market Surveillance?

The US FDA defines post-market surveillance as:

“The active, systematic, scientifically valid collection, analysis, and interpretation of data or other information about a marketed device.”

Thus, if you are bringing a particular medical device into the market, you must ensure that your product is risk-free. It is possible that certain risks can manifest over time, with the regular use by end-users. This is where post-market surveillance comes into play.

Thus, post-market surveillance denotes the monitoring of a medical device on the market for safety. It is a part of pharmacovigilance, i.e. drug and device safety.

Purpose of Post Market Surveillance

Post-market surveillance is crucial for a medical device’s lifecycle. When your medical device is used by a larger population, as compared to clinical trial participants, a lot more data and information becomes available.

As a result, you will get real-world evidence that provides a holistic picture of the safety and efficacy of your medical device.

Post-market surveillance aims at the following:

  • Monitoring safety and efficacy of a medical device in the projected patient population
  • Finding of adverse events
  • Compliance with regulatory requirements
  • Evaluation of a new device’s performance with current standards of care

Let us look at, for example, your closed-loop artificial pancreas system that is now available on the market. Its intended use is to facilitate patients with type 1 diabetes to adjust their blood glucose levels in an automated manner. During clinical trials, your device worked perfectly. However, on the market patients detect certain flaws that reduce their safety and efficacy.

Since you have a post-market surveillance plan in place, you can identify these flaws and make the necessary corrections.

Let us now look at the steps involved.

Post-Market Surveillance Process
  • Develop medical device: The R&D team in your company has improved on existing closed-loop artificial pancreas systems currently available.
  • Perform initial clinical evaluation: The medical device now undergoes all mandated evaluations to prove its safety and efficacy in a target population.
  • Place the improved medical device on the market: The closed-loop artificial pancreas system is now made available on the market.
  • Continuous surveillance of your medical device on the market: The new medical device is constantly surveilled for any safety issues.
  • Detection of adverse events: You get reports that end-users are facing certain safety and efficacy issues with your medical device.
  • Update clinical evaluation and risk management: These adverse events are used to update the medical device’s clinical evaluation and risk management data.
  • Decide on measures/action: You will now need to decide on what measures or actions your company must take.
  • Action required?: Is any action or measure required in the first place?
  • Perform actions and improve the product if necessary: The medical device now needs to be fine-tuned to remove the flaws.
  • Place the improved medical device on the market: The improved medical device is now ready to be sold on the market.

Value of Post Market Surveillance

There are different stakeholders for the medical device that you have placed on the market, these include:

  • You (the manufacturer)
  • Clinicians
  • Provider organizations
  • Regulatory agencies

Let us look at the importance of post-market surveillance for each stakeholder.

You (the Manufacturer)

Post-market surveillance gives you extra information on the disease in question. In the example cited, it is type 1 diabetes. You will also be able to compare your device with similar marketed devices.

The information that you get will help you to fine-tune your strategies concerning pricing, marketing, and clinical features of your product. You can consequently develop an upgraded product.

Clinicians and Provider Organizations

Post-market surveillance will provide clinicians and provider organizations with information about real-world patient populations. Such populations are often different from clinical trial participants.

With the information obtained, clinicians can make informed treatment choices.

Regulatory Agencies

Information obtained from post-market surveillance of any given medical device helps regulatory agencies decide which products are the safest, most efficacious, and cost-effective.

Post Market Surveillance Requirements

The main regulatory requirements for post-market surveillance are:

  • US FDA 21 CFR Part 822: This details the post-market surveillance requirements in the USA.
  • MedWatch: This is the FDA’s medical product safety reporting program for healthcare professionals, patients, and consumers.
  • EU MDR: The EU requirements for post-market surveillance.

How to Conduct Post-Market Surveillance in an eQMS

As a manufacturer of medical devices, you could take the following steps to conduct post-market surveillance using digital post-market surveillance solutions:

  1. Create a Post-Market Surveillance Plan
  2. Implement the Plan
  3. Generate a PMS Report Based on the Findings
  4. Perform Vigilance Related Tasks
  5. Use Pre-Configured Forms for CAPAs, Complaints, NCs, Etc.

Let us look at it one-by-one.

1. Create a Post-Market Surveillance Plan

You must continuously collect and monitor data generated for your medical device. This PMS plan is part of the medical device technical file.

The post-market surveillance plan lists out the requirements needed for your post-market surveillance. The following details are addressed in the PMS plan:

  • Information about serious adverse events and corrective actions
  • Facts on non-serious incidents and undesirable side effects, if any
  • Technical information, databases, and registers
  • Feedback and complaints, CAPAs, Non-Conformances, etc., given by end-users, distributors
  • Information on similar medical devices

With an electronic quality management system (eQMS), you will be able to cover all processes related to the PMS plan, such as CAPAs, complaints, and others which will help you save time and make regulatory compliance much easier.

2. Implement the Plan

Now that you have generated the PMS plan, you need to implement it.

Efficient QMS software will help you streamline and automate processes reoccurring processes like data collection, routing, approvals, follow-ups, reminders, email notifications, and more.

Moreover, QMS software for medical devices like SimplerQMS allows you to record NCs, audit findings, complaints, deviations, and other issues, link, and process any number of CAPAs, based on the severity.

3. Generate a PMS Report Based on the Findings

A variety of documents are generated during the PMS processes.

Post-market surveillance reporting should contain a summary of all the outcomes and decisions that were derived when the PMS data has been collected and analyzed.

It will also describe the corrective and preventive actions (CAPAs) taken by your company. Another important piece of documentation is the Periodic Safety Update Report (PSUR). The latter summarizes the results and conclusions obtained when the PMS, PMCF, and vigilance data have been analyzed.

With QMS software all the documents generated throughout your PMS activities are well organized, hyperlinked, and stored in a single, highly secure, cloud-based system. Solutions, like SimplerQMS, allow you to get an overview of NC-, Complaint-, CAPA-trending thanks to automated KPI reporting capabilities.

Vigilance is beneficial for planning post-market clinical data information when the technical documentation of the device is done.

With a vigilance system in place, you can enable the uncovering of unknown adverse events, which will help prevent any future occurrence of such incidents.

Using eQMS reporting capabilities, you can analyze data, identify patterns, and better understand the root cause behind every complaint, non-conformance, deviation, or any other issue. This allows you to trace different quality events back to their root cause as well as correct areas of concern before they come to reality.

5. Use Pre-Configured Forms for CAPAs, Complaints, NCs, Etc.

With so many documents being generated during the PMS, you must have a proper form management process for distributing, processing, completing, and managing forms in place. This will allow you to get better data, streamline complaince and become more efficient.

When you have efficient eQMS software, like SimplerQMS, you are enabled with a powerful form and template management module that includes – pre-configured forms for generating CAPAs, NCs, registering complaints, etc., automated workflows, automatic data collection, and more.
