Post market surveillance, or PMS, is an important tool to ensure the safety, efficacy and performance of medical devices. This type of study assesses the safety of medical devices in the post market environment, and is conducted once a product has been placed on the market.

In this article, we will cover all the aspects of post market studies and their importance in the medical device industry.

Definition of Post Market Study

A post market study or a post market clinical evaluation is an objective assessment of the clinical performance of a medical device after it has been made available to the public. Strict rules and guidance from regulatory bodies assist in ensuring that the devices sold on the market are of safe and acceptable quality. Post market studies are a form of proactive surveillance to help ensure patient safety and public health.

The objective of a post-market study is to identify possible safety and effectiveness issues, evaluate their severity, assess whether corrective measures need to be taken, and recommend further research if required. Such studies also aid in gaining better insight into the effectiveness of device performance as treatments change throughout its lifecycle, capturing new user experience data which might have not been seen during initial clinical evaluations prior to launch. As such, post-market studies provide critical information by helping manufacturers answer questions related to efficacy, usability and user satisfaction following launch.

Additionally, results can be used by manufacturers to build product profiles when given access to medical claims databases or track usage within product registries. This ensures that they can continue meeting customer needs while predicting future trends. Post-marketing surveillance activities must be considered part of a company threat identification analysis as changes in user experience/performance can indicate an otherwise unanticipated issue or warning signal indicating potential non-compliance or reduction in safety/efficacy performance due to wear or age related issues.

Benefits of Post Market Study

A post-market study is a critical step in the quality assurance process of medical devices. It can uncover potential quality issues and improve the safety of products for patients. Post-market studies also provide important feedback that can be integrated into the design and production of future products, giving manufacturers a competitive edge in the marketplace.

In addition to helping ensure a quality product enters the market, post-market studies serve several other functions. By identifying any unexpected outcomes related to device use, these studies help to maximize patient health and safety and may ease regulatory concerns about a particular device or new technology. They can also reveal whether an education program was effective in teaching healthcare providers how to properly administer a new device or if changes must be made to make it easier or safer for practitioners and patients alike. Finally, they help provide data that will enable manufacturers to further enhance their existing products or create even more advanced devices in the future.

Post-market studies are also necessary for validation and/or enhancing regulatory submissions or responses such as 510(k)s or PMAs that might indicate some form of risk verification is required before approval by applicable government bodies such as FDA (US Food & Drug Administration). Through this type of evaluation, data can be collected on key topics such as how well the product works under real-world conditions, long-term safety factors, complaint rates; feedback from user evaluations are also important aspects when conducting these surveys which further aids manufacturers with product improvement efforts through useful analytics based on relevant insights from patient and healthcare practitioner use cases as well as during evaluation by involved governmental bodies for approval processes.

Regulatory Requirements

When developing a medical device, manufacturers must follow specific regulatory requirements set by FDA.

Post-market studies are essential in understanding the safety and efficacy of a device after it has been released to the public.

This section will discuss the requirements for conducting a post-market study as well as the benefits of these studies.

FDA Post Market Requirements

The U.S. Food and Drug Administration (FDA) closely monitors the manufacturing, distribution, and marketing of medical devices sold in the United States. All medical device manufacturers must meet FDA requirements for post-market surveillance of their products. This means that even after the device is approved for sale, manufacturers must continue to collect information about how it performs in the real world over time.

To ensure that any potential safety risks are identified quickly, and corrective action taken as needed, the FDA requires medical device manufacturers to engage in post-market surveillance activities such as collecting customer feedback, continuously monitoring incident reports, evaluating any changes made to device components or design specifications that could affect performance or safety, and conducting field studies with users or healthcare professionals.

Post-market surveillance allows identification of any problems or issues with a device within a reasonable timeframe so they can be addressed by either corrective measures and/or warnings to providers and patients using the product(s). It also provides a mechanism for capturing long-term safety profiles of these products over time and establishing long-term safety tracking estimates using reliable data sources such as user feedback surveys, consumer complaints databases, clinician trials databases or other third-party data sources.

In addition to these activities, FDA may also require certain types of medical device manufacturers to submit regular post-market study reports which outline the results of their post-market surveillance efforts including all adverse events associated with particular devices. Such studies are designed to provide additional insight into how a particular device is performing in clinical use so that appropriate measures may be taken if necessary. Such reports typically include detailed case histories outlining specific incidents related to any observed effects as well as recommendations from health care providers involved with these cases where applicable.

International Post Market Requirements 

Medical device manufacturers are required to undertake various post-market studies and associated activities in order to meet international regulatory requirements. These activities include, but are not limited to:

– Obtaining feedback from patients and healthcare professionals, analysing product performance data, implementing corrective and preventive action plans, monitoring adverse events or incidents, conducting product safety audits and performing quality system reviews.

– Post market surveillance studies ensure that any changes made over the life of the product are monitored and that any health hazard posed by any given product is identified quickly. In addition to monitoring, investigations must be made into the root cause of product problems and preventive actions must be implemented where necessary.

– Appropriate Post Market Surveillance (PMS) strategies should be established in countries where the medical device is placed on the market. The studies should focus on user experience with a particular model or type of device as well as identifying uncommon complications specific to a given medical procedure.

– Systematic Quality Management Audits (QMA) must also be conducted periodically within an organisation’s Quality Management System (QMS). This process ensures that processes and procedures consistently meet industry standards as well as being compliant with applicable national regulations. Quality system reviews may require additional control elements such as design control standards, biocompatibility tests or verification tests; as well as regular supplier audits where relevant subcontractors provide components or services for use in products covered by the QMS.

Design of Post Market Study

A Post Market Study is an essential part of the medical device design process, as it assesses the performance of the device in the market. It provides data which can be used to analyze the performance of the product, and can also provide insights into how to improve the design.

This article will discuss the process and design of a Post Market Study.

Planning the Post Market Study

Planning a post market study is crucial in making sure that the medical device will meet user needs and safety regulations after its introduction to the market. Developing an effective post market study design involves taking several factors into consideration including selecting user demographics, setting up objectives and deciding on target outcomes.

User Demographics: Before embarking on the medical device post market study, it is important to first identify who you will be targeting. Establish the age group, gender, location, lifestyle, or any other demographic information related to potential users of your device. Defining a user profile aids in identifying targets for surveys or interviews as well as helps collecting data during the course of the trial.

Setting Objectives: Once you have selected your target demographics for conducting a post market study, it is important to set clear goals and objectives before initiating the project. Identifying objectives such as measuring user satisfaction levels or tracking incidence rates of a particular problem enables researchers to focus their results more accurately.

Outcome Targeting: It is important for researchers to consider both short-term and long-term objectives depending on their needs before designing a post market study. For example, if you want to measure user satisfaction levels more precisely after 12 weeks of using the medical device then it may be beneficial to conduct two surveys at 6 week and 12 week intervals respectively following usage. Analysing responses from both surveys could give an indication if satisfaction had risen over time or whether there were any problems that occurred during usage which could then be addressed before conducting further studies in different populations or additional tests/trials involving subjects using similar devices as comparison.

Data Collection

Data collection is a critical component of a successful post market study. It involves identifying the types of information that should be obtained and then obtaining it through appropriate methods. Depending on the study, data collection may include surveys, interviews, focus groups, records review, observational studies or some combination of these methods.

Surveys are typically used to collect information from a wide range of participants regarding current practices and knowledge. Interviews are best for getting detailed or personal information from a limited number of participants – including those with specific expertise in the medical device in question. Focus groups involve interviewing 8 to 10 people at once in order to get their reactions concerning the medical device’s features and potential issues or risks associated with its use. Observational studies allow researchers to observe how people interact with the medical device in different contexts; this approach is especially useful for user interfaces or display systems. Additionally, records review identifies and extracts relevant data from datasets compiled by past studies or established databases such as electronic health records (EHR).

Properly designed questionnaires, interview protocols and forms should be developed before any data is collected to ensure accurate and valid responses are collected during post market studies.


Post-market studies are a critical part of the medical device lifecycle and must be carefully planned in terms of design, statistical analysis and interpretation. An effective post market study evaluates how the device performs in everyday clinical use with regards to safety, effectiveness, and mode of performance. It also helps identify potential areas for improvement.

Analysis is a key step within the post market study process. An appropriate statistical analysis should be selected based on study aims, data sources, endpoints and sample size. Statistical analyses should consider baseline comparability of treatment groups to identify any inherent bias in the cohort Design of Experiment (DOE) aspects should also be considered depending on specific purpose as well as accuracy desired in effect size estimation. Sample size calculation will also be essential for adequate precision and power considerations when research questions involve hypothesis testing.

It is important to recognize that post-market studies require careful consideration prior to implementation due their retrospective nature; longer timelines, more complexity in subject selection, data collation and interpretation often encountered than pre-market engagements are the norm. A robust plan design where appropriate scientific strategy is adequately supported with intuitive sample size estimations from trial feasibility will ensure successful outcomes from a post-market engagement.

Post Market Surveillance

Post Market Surveillance is the process of monitoring how medical devices are used in the real world. It involves collecting data from user surveys, hospital reports, and other sources, as well as analysing it in order to provide feedback to the regulatory authorities. It is an essential part of the post-market study process and helps make sure medical devices remain safe and effective.

Let’s dive into the details of what post market surveillance entails.

Developing a Post Market Surveillance Plan

Post market surveillance is an important component of the risk management process for medical devices. This type of structured approach to collect, analyse and act on information from real-world use helps to identify risks and opportunities, optimize product performance and satisfy regulatory requirements. To ensure a successful post market surveillance program, it is essential to define an effective surveillance plan.

The planning stage of a post market surveillance program requires consideration of internal resources, customer preferences, data sources and analysis techniques. Establishing procedures is key to ensure compliance with regulatory requirements. The following list offers some direction on developing a post market surveillance plan:

-Define customer segments and tailor the message accordingly

-Identify sources for data collection (e.g., complaints, Adverse Events Reports)

-Review applicable requirements for collection and analysis of collected data

-Design feedback plans for taking corrective action in response to reported incidents or issues

-Outline procedures for reporting required information (e.g., changes to product labelling)

-Develop monitoring systems for tracking trends in customer feedback

-Determine processes for reporting adverse event information as mandated by relevant regulations

Collecting and Analysing Surveillance Data

Post-market surveillance is the process of collecting and analysing data to understand how a medical device performs in its intended use after launch. Post-market surveillance helps manufacturers monitor product safety and mitigate potential risks during commercialization. This is important to ensure patient safety, support product retention and improve customer satisfaction.

The first step in post market surveillance is collecting data from the marketplace. This can include patient feedback from clinicians or users, field observations from sales representatives or service engineers, laboratory testing of devices or components, and close monitoring of activities at competitors. Collected data needs to be organized in a format that allows for easy analysis, such as spreadsheets or databases.

The second step consists of analysing the collected data for trends related to device performance. Devices are observed for compliance with performance criteria, such as accuracy and reliability over time; rates of occurrence for unintended consequences including recalls; variability between batches; any specific changes in manufacturing process that may have occurred; changes in laws and regulations affecting the marketplace; interactions with other products on the market, etc. The goal is to identify patterns so that potential problems can be quickly identified and corrective action taken if necessary.

Once collected and analysed, any improvements that could be made should be implemented as soon as possible during the post-market period rather than waiting until a problem occurs. This includes changing product designs, conducting education campaigns on proper use of products, adjusting collaborations with suppliers or making marketing changes to enhance visibility across target groups. Post-market surveillance provides opportunities for continued growth by identifying areas where improvements can be made while also demonstrating a robust commitment to consumer safety within a highly regulated medical technology industry.

Reporting and Tracking

Post Market Surveillance is an essential component of the oversight of medical products. It is the process of obtaining information from ongoing product use in the market to assess, review, and monitor safety, effectiveness, and quality changes after initial market authorization. This information helps confirm that a device provides a benefit when used as intended, demonstrates acceptable safety profile without any unexpected side-effects or problems associated with it and performs as claimed by the manufacturer.

Healthcare professionals should report any potential adverse events associated with medical devices directly to the manufacturer and/or their regulatory agency. The reporting should include specific details such as date, type of product associated with event and clinical outcome of the event. Furthermore, manufacturers should establish appropriate write-back systems so that they can provide timely feedback to healthcare professionals who have reported events and share relevant information regarding safety issues originating from post marketing surveillance activities.

The purpose of tracking is to enable manufacturers to better understand product usage in order to identify any trends or emerging problems. Additionally, tracking can help confirm knowledge gained through post market surveillance reports, aid in preventative actions when needed and improve communication between all relevant stakeholders (e.g., healthcare providers, regulators). Tracking strategies should include electronic record-keeping activities for product performance such as performance logs for each device’s usage history and a review system for any products returned from customers or other sources. Manufacturers should also be proactive in verifying the compatibility between their products and those of other manufacturers where applicable (eg laboratories) in order to ensure that safe interactions are occurring between different systems when being used together.


The medical device post market study serves as an essential source of data for further research and as an evaluation tool. It is used to identify any issues that may arise from devices currently in the market, helping to assess the long-term risk factors associated with its use. It is also a way to monitor changes in regulatory requirements and identify areas of concern that need further investigation.

Additionally, it provides valuable information on device performance after its initial launch, informing doctors, hospital staff, regulatory agencies and other industry stakeholders about the safety and effectiveness of the product during long-term use. The post market study is also useful in obtaining feedback from practitioners on how a device is being used in practice, which can be used in developing manufacturing standards and improving product design.

In conclusion, the medical device post market study serves as an invaluable tool for assessing safety, effectiveness, reliability and performance of medical devices.
