In the field of healthcare, ensuring the safety and efficacy of medical devices is of utmost importance.
This is where postmarketing surveillance (PMS) studies come into play.
In this article you will learn about:
Postmarketing surveillance is a crucial process that involves monitoring the safety and effectiveness of medical devices after they have been approved for use in the market.
In Japan, PMS studies play a significant role in safeguarding public health and maintaining the integrity of the healthcare system.
This article will delve into the postmarketing surveillance studies conducted in Japan, highlighting the regulatory framework, reporting requirements, and the importance of these studies in ensuring the safety of medical devices.
In addition, Sofpromed will be introduced as a CRO specialized in managing PMS studies in Japan.
The Importance of Postmarketing Surveillance Studies
Postmarketing surveillance studies are essential for several reasons.
Firstly, they provide valuable insights into the real-world performance and safety of medical devices.
While premarket clinical trials provide crucial data, they are often limited in terms of sample size and duration.
Postmarketing surveillance studies allow for the collection of data from a larger population over an extended period, enabling the identification of potential risks and adverse events that may not have been apparent during the premarket phase.
Secondly, postmarketing surveillance studies enable regulatory authorities to take appropriate actions in response to safety concerns.
By actively monitoring the safety profile of medical devices, regulatory bodies can identify and address any emerging risks promptly.
This may include issuing safety alerts, updating labeling information, or even initiating product recalls if necessary.
The continuous monitoring of medical devices through postmarketing surveillance studies helps ensure that any potential risks are mitigated effectively, protecting the health and well-being of patients.
The Regulatory Framework in Japan
Postmarketing surveillance studies in Japan are overseen by two key regulatory bodies: the Pharmaceuticals and Medical Devices Agency (PMDA) and the Ministry of Health, Labor, and Welfare (MHLW).
These organizations work in tandem to collect adverse event data, promote safe usage of medical devices, and take necessary regulatory actions if required.
The PMDA is an independent administrative agency responsible for reviewing and approving medical devices, conducting inspections, and collecting and analyzing adverse event reports.
The agency works closely with the MHLW to ensure the safety and quality of medical devices in Japan.
The MHLW, on the other hand, sets safety standards and regulations for medical devices, registers manufacturers, grants licenses, and monitors the PMDA’s activities.
Reporting Requirements in Japan
In Japan, manufacturers and Marketing Authorization Holders (MAHs) are required to report adverse events associated with medical devices.
Adverse events refer to any unexpected or undesirable effects that occur following the use of a medical device.
The reporting timeline depends on the severity of the adverse event.
Serious adverse drug reactions must be reported to the MHLW within 15 days, while non-serious adverse events are reported annually.
It is crucial for manufacturers and MAHs to comply with these reporting requirements to ensure the timely identification and management of potential risks.
To facilitate the reporting process, the PMDA has developed an online system called the Electronic Transmission of Individual Case Safety Reports.
This system allows for the efficient submission of adverse event reports and ensures that the necessary information reaches the regulatory authorities promptly.
Additionally, adverse events occurring in other countries with devices that are approved in Japan are also reportable to the MHLW.
Postmarketing Surveillance Process in Japan
The postmarketing surveillance process in Japan involves several key steps to ensure the ongoing safety and effectiveness of medical devices.
These steps include:
Recording and Reporting Adverse Events
Manufacturers and MAHs are responsible for recording and reporting any adverse events associated with their medical devices.
This includes both serious and non-serious adverse events, as per the reporting requirements mentioned earlier.
Data Collection and Analysis
The PMDA and the MHLW collect and analyze adverse event data to identify any potential safety concerns or emerging risks.
This involves conducting thorough assessments of the reported adverse events and determining the appropriate regulatory actions.
Safety Alerts and Product Recalls
If a safety concern is identified through postmarketing surveillance studies, regulatory authorities can issue safety alerts to healthcare professionals and the public.
In more severe cases, product recalls may be initiated to ensure the removal of potentially unsafe medical devices from the market.
Labeling Updates
Postmarketing surveillance studies may also lead to updates in the labeling information of medical devices.
This includes providing additional warnings, precautions, or usage instructions to enhance patient safety and promote appropriate device use.
Comparing Postmarketing Surveillance Strategies
Japan’s postmarketing surveillance strategy is comparable to those employed in the United States, European Union, and China.
However, there are certain unique aspects of the Japanese system that contribute to its effectiveness.
The Ministry of Health, Labor, and Welfare has taken significant steps to improve the transparency and efficiency of the review system, making the approval process in Japan equivalent to or faster than those in North American and European markets.
Additionally, Japan’s aging population and the increasing prevalence of chronic diseases have necessitated the implementation of robust postmarketing surveillance measures to ensure the safety of medical devices used by a vulnerable population.
