Therefore, it is important for Medical Device QA/RA Professionals to know in detail about EU MDR 2017/745. In today's blog, we are going to discuss about Scrutiny Procedure of EU MDR 2017/745. 


Let's get into the topic.


SCRUTINY PROCEDURE

The Scrutiny procedure in EU MDR is intended to improve the overall quality of conformity assessments performed by the notified body for high-risk category devices. The Scrutiny is for additional review & improves transparency in the conformity assessment process.

As per Article 54 & 55, manufacturers of Class III Implantable Devices & Class IIb active devices intended to administer or remove medicinal products are subjected to scrutiny.

Apart from Manufacturers of Medical Devices, Scrutiny also impacts the Notified Bodies, Competent Authority, MDCG & Expert Panel.

The following are the roles & responsibilities of Manufacturers, Notified Body, Competent Authority, MDCG & Expert Panel:

 

Manufacturer:

The Manufacturer of Medical Device submits the Conformity Assessment documentation & Summary of Safety & Clinical Performance to the Notified Body.

 

Notified Body:

The Notified Body performs conformity assessment of the documentation submitted by the manufacturers of the Medical Device. As per “Article 55, Mechanism for scrutiny of conformity assessments of certain Class III & Class IIb devices”, the Notified Body notifies the competent authority about the certificates it has granted by performing conformity assessment in accordance with Article 54(1). Such notification shall take place via electronic system as referred in Article 57. The notification shall include the following details.

The Summary of Safety and Clinical Performance in accordance with Article 32.

Conformity Assessment report by the notified body.

The Instructions for Use as referred in Section 23.4 of Annex I.

If applicable, scientific opinion of the expert panels as referred in Section 5.1 of Annex IX or Section 6 of Annex X. If the Notified Body decided not to follow the advice from Expert Panel, an appropriate justification shall also be included.

 

Competent Authority:

The Competent Authority determines the need to perform the additional scrutiny of the Notified Bodies Conformity Assessment of Documentation. The Competent Authority makes such decisions in accordance with the following articles.

Article 44: Monitoring & re-assessment of notified bodies

Article 45: Review of notified body assessment of technical documentation and clinical evaluation documentation

Article 46: Change to designations & notifications

Article 47: Challenge to the competence of notified bodies

Article 94: Evaluation of devices suspected of presenting an unacceptable risk or other non-compliance

The Competent Authority also coordinates with MDCG, if required.

 

Medical Device Coordination group (MDCG):

The MDCG directs the scrutiny process & coordinates with the expert panel, if required.

 

Expert Panel:

The Expert Panel provides scientific expertise & expert opinion on the conformity assessment. The Expert Panel can advise restrictions to medical indications or intended purpose, can limit the certificate validity, propose updates to PMCF Plans, IFU’s, SSCP.

 

Article 54: Clinical Evaluation consultation procedure for certain

class III and class IIb devices

When performing a conformity assessment of Class III & Class IIb Medical Devices, apart from the procedures specified in “Article 52, Conformity Assessment Procedures”, the notified body can also follow the procedure regarding Clinical Evaluation Consultation as specified in Section 5.1 of Annex IX or Section 6 of Annex X.

The notified body shall notify the competent authority via electronic system as referred in Article 57 of whether the above-mentioned procedure of article 54 is applied or not. The notification shall be accompanied by clinical evaluation assessment report.


Now I hope you have acquired some basic knowledge about Scrutiny Procedure as per EU MDR 2017/745. We will meet again with another valuable topic related to Biomedical Engineering, Medical Device, Healthcare.

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.
