In today's blog, we are going to discuss about IEC 62304.


IEC 62304 states the requirements for Medical Device Software. Satisfying the requirements of IEC 62304 is an important task in order to ensure the safety of patients and efficacy of software used in treating the patients.


Therefore, it is important for Medical Device QA/RA Professionals to understand about Software Configuration Management & Problem Resolution Process requirements as per Clause 8 & 9 of IEC 62304. 

 

Software Configuration Management Process


Configuration Identification

A scheme for unique identification of configuration item and its version to be controlled shall be established by the manufacturer of the medical device software according to the development and configuration planning.

The configuration items and its versions comprising the software system configuration shall be documented by the manufacturer of medical device software.

The details of the SOUP Configuration items for example title, manufacturer details & unique SOUP designator shall be documented by the manufacturer of the medical device software. The unique SOUP designator can be a version, release date, patch number or an upgrade designation.

These requirements are applicable for Class A, B & C, medical device software.


Change Control 

A configuration items shall be changed by the manufacturer of the medical device software only after the approval of change requests. The Change control process should be followed for making decisions regarding the approval of change requests.

The change shall be implemented as specified in the change requests. Activities that need to be repeated because of change implementation shall be identified and performed by the manufacturer of the medical device software. The implemented change shall be verified by the manufacturer.

The details regarding the dependencies & relationships between change requests, approval of change requests, related problems reports shall be maintained by the manufacturer of the medical device software.

The details regarding the history of controlled configuration items including the system configuration shall also be maintained by the manufacturer of the medical device software.

These requirements are applicable for Class A, B & C, medical device software.

Software Problem Resolution Process

Each problem detected in the medical device software shall be recorded in the problem report by the manufacturer of medical device software. The problem reports shall include information about the criticality of the problem detected in the medical device software & any other information that can help in the problem resolution.

Problems can be discovered before or after the release of medical device software into market. Problems can also be discovered inside or outside of the manufacturer’s organization.

Each problem shall be investigated to identify the root cause & outcome of the investigation shall be documented by the manufacturer of the medical device software. Any actions needed for the resolution of problem can be proceeded via creation of change requests. If there are no actions required, a rationale can be provided.

The above change control steps shall be followed for the approval & implementation of change requests.

All the relevant parties depending upon the situation shall be advised about the existence of the problem by the manufacturer of the medical device software.

Appropriate records for problem reports, their resolution & verification shall be maintained by the manufacturer of the medical device software.

The problem reports shall be analyzed for any trends. The resolution shall be verified by the manufacturer of medical device software with respect to adverse trends, complete implementation of change requests and closure of problem reports.

The relevant test documentation with appropriate details shall be maintained by the manufacturer of medical device software.

These requirements are applicable for Class A, B & C, medical device software.

 

Now I hope you have acquired some basic knowledge about Software Configuration Management & Problem Resolution Process as per Clause 8 & 9 of IEC 62304. We will meet again with another valuable topic related to Biomedical Engineering, Medical Device, Healthcare.

IEC 62304 states the requirements for Medical Device Software. Satisfying the requirements of IEC 62304 is an important task in order to ensure the safety of patients and efficacy of software used in treating the patients.


Therefore, it is important for Medical Device QA/RA Professionals to understand about Software Maintenance Process requirements as per Clause 6 of IEC 62304. 

 

Software Maintenance Process

The Software Maintenance is performed once the medical device software is released in the market. There are multiple reasons for performing maintenance activities which includes correcting issues & bugs and to keep up with the customer needs etc. IEC 62304 states the requirements for Medical Device Software Maintenance Process.

Software Maintenance Plan

The Software Maintenance Plan shall be established by the manufacturer of the medical device software. The Software Maintenance Plan shall address the following:

The Procedures for addressing the feedbacks once the medical device software is released into the market.

The Criteria for determining whether the feedback can be considered as a problem.

The Problem resolution process & Configuration Management Process.

The Procedures for evaluating and implementing the upgrades, bug fixes, patches, obsolescence of SOUP.

These requirements are applicable for Class A, B & C, medical device software.

 

Problem and Modification Analysis

 

Document and Evaluate Feedback:

The feedbacks of the market released medical device software shall be monitored, documented and evaluated by the manufacturer of the medical device software to determine the existence of problems in the released medical device software.

The Problems identified shall be recorded in Problem Report as per Problem Resolution Process specified in IEC 62304.

The Problem Report shall include deviations from specification and actual or potential adverse events.

The effects of the problem on the safety of the medical device software released into the market shall be evaluated in the Problem Report. The changes needed in the medical device software for addressing the problem shall also be evaluated in the problem report.

The requirement is applicable for Class A, B & C, medical device software.

 

Software Problem Resolution Process & Change Requests:

The Problem Resolution Process as per IEC 62304 shall be used by the manufacturer of the medical device software to address problem reports.

In addition to the Problem Resolution Process, each change requests raised to address the problem shall be analyzed by the manufacturer with respect to its effect on released medical device software and the systems with which it interfaces, and the organization.

Each change requests which modify the released medical device software shall be evaluated and approved by the manufacturer. The Change request means a documented specification about the change.

The Users and Regulators shall be communicated by the manufacturer about any problems in the released medical device software. The Users and Regulators shall also be communicated about the consequences of continued unchanged use of the software.

The requirement is applicable for Class A, B & C, medical device software.

 

Implementation of Modification

Software Development Process as per IEC 62304 need to be identified and repeated by the manufacturer of medical device software for implementing the required software modification.

Modifications made to the software shall be released by the manufacturer of medical device software. The release can be a full re-release of software system or only as a software item comprising of changes and tools to install the changes to an existing system.

The requirement is applicable for Class A, B & C, medical device software.


Now I hope you have acquired some basic knowledge about Software System Maintenance Process as per Clause 6 of IEC 62304. We will meet again with another valuable topic related to Biomedical Engineering, Medical Device, Healthcare.
