The Quality Manual describes the scope of the Quality Management System, its documented procedures and a description of their interactions.
The QMS described in this Quality Manual applies to all standalone software medical devices developed by the Clinical Scientific Computing team at Guy's & St Thomas' NHS Foundation Trust.
Guy's & St Thomas' NHS Foundation Trust is the largest and one of the UK's busiest and most successful foundation trusts, with a long history of high quality care, clinical excellence, research and innovation. Royal Brompton and Harefield hospitals became part of Guy's and St Thomas' in February 2021, bringing together world-leading expertise and research in heart and lung disease.
Guy's & St Thomas' NHS Foundation Trust is also a manufacturer of software medical devices.
The following table only gives an overview of the most relevant regulation and standards. For a comprehensive overview, see the list of applicable standards.
| Standard / Regulation / Law | Why Applicable? |
|---|---|
| UK MDR 2002 | Devices placed "service" within GSTT |
| ISO 13485:2016 | QMS required by essential requirements of MDD |
| ISO 14971:2019 | Risk management for medical devices |
| IEC 62304:2006 | Software development for medical devices |
| IEC 62366-1:2015 | Usability evaluation for medical devices |
| Standard | Certificate |
|---|---|
| ISO13485:2016 | [MD 796362.pdf](records/certification/MD 796362.pdf) |
The following sections of ISO 13485:2016 are non-applicable because all products developed under this QMS are stand-alone software:
| Section | Title | Rationale |
|---|---|---|
| 6.4.2 | Contamination control | The CSC Team develop software only |
| 7.5.2 | Cleanliness of product | The CSC Team develop software only |
| 7.5.4 | Servicing activities | The CSC Team develop software only. Software updates are controlled under change management and are not considered servicing. |
| 7.5.5 | Particular requirements for sterile medical devices | The CSC Team develop software only |
| 7.5.7 | Particular requirements for validation of processes for sterilisation and sterile barrier systems | The CSC Team develop software only |
| 7.5.9.2 | Particular requirements for implantable medical devices | The CSC Team develop software only |
| 7.6 | Control of Monitoring and Measuring equipment | Any measurements for quality/performance of processes will be made by ad-hoc software built by the Development Lead of a particular project or the Quality Representative |
SaMD developed within the QMS by the CSC Team are deployed within GSTT for use internally only and will not be distributed outside The trust, so are considered to be put "in service" rather than on the market as per MDR Article 5 and therefore exempt from the full regulation. The QMS is compliant with the conditions for exemption.
We are guided by our values: putting patients first, taking pride in what we do, respecting others, striving to be the best and acting with integrity.
As part of King's Health Partners, an academic health sciences centre, we are pioneers in health research, and provide high quality teaching and education. This partnership helps us provide the latest treatments alongside the best possible care.
We are committed to complying with all applicable legal requirements in order to facilitate the translation of software medical devices from R&D into routine clinical care. This is balanced with a need to adopt modern processes of the internet-era to respond to people’s raised expectations and the rise of data-driven technologies.
As developers of software medical devices that could have an impact on safety, we commit to minimising clinical risks in compliance with appropriate legal and professional standards to ensure we support safe and effective care. In order to facilitate this, we commit to a radically open and transparent development process that allows scrutiny from all stakeholders and encourages a culture of honesty, inclusiveness and collaboration.
As members of a vibrant academic health sciences centre, we commit to working in collaboration with our partners in academia and colleagues in the wider GSTT Trust to facilitate the translation of research work into products that can contribute to patient care in a safe and efficient manner.
In the spirit of continuous improvement, we will review this quality policy on an annual basis to ensure we continue to effectively communicate with everyone within our organisation the goal of the QMS as well as to ensure it is fit for purpose on top of the shifting landscape of digital health.
In order to meet the Quality Policy we define the following objectives and their respective measurements and targets:
| Objective | Measurement | Target |
|---|---|---|
| Minimise the number of QMS-related documents that exist outside of software product git repositories, e.g. records. | Number of documents on shared drive | >90% of records |
| Minimise the time from when new code is ready to be release to application deployment. | Time from tagged release in github to clinical deployment | 2 weeks |
| Minimise manual documentation generation | Number of documents written without a template | 5 |
| Increase the number of collaborative developments supported by QMS | Number of additional developments | >2 developments per year |
| Increase the number of contributors and reviewers of QMS documents | Number of staff trained in QMS management | 1/3 of core team |
| Comply with all applicable requirements in ISO 14971:2019, BS EN 62304:2006, BS EN 62366:2015 and DCB0129, UKMDR2002 | Internal/External audit | All standards and Regs |
The quality objectives will be reviewed at management reviews and on a frequent basis to ensure they remain inline with the CSC department goals.
Not all work projects conducted by the CSC are required to adhere to full ISO 13485:2016 quality management system. The criteria for applicable projects are:
- It must be a medical software development project.
- It will be deployed clinically within GSTT.
- It is a medical device in accordance with the MHRA classification scale.
The CEO is responsible for ensuring that the organisation complies with all legal requirements as well delivering safe and effective care as judged by the Care Quality Commission. The responsibility to comply with The Medical Devices Regulations 2002 is delegated to the Medical Director who is supported by the Chief Biomedical Engineer. The Quality Management Officer (QMO) works with the Chief Biomedical Engineer to ensure that the QMS effectively supports the development of software medical devices.
The Head of Medical Physics represents the role of top management. They are responsible for:
- The allocation of resources to the CSC department for quality management

The staff filling these roles are found in CSC I.001 Roles.
-
The CSC department normally uses only staff who are permanently employed by, or under contract to, the Guys’ & St Thomas’ Hospital Foundation Trust.
-
For each task to be performed, the CSC Department uses staff who have the appropriate combination of academic and/or professional qualifications, training, experience, and skill. The use of staff undergoing training is acceptable, provided that they are supervised and that the proportion of these to the qualified staff is not such as to have an adverse effect on the quality of the work undertaken.
-
The CSC Department has documented policy and procedures to ensure that existing and new staff have and maintain relevant academic and/or professional qualifications, technical skills, and professional expertise.
-
The CSC department maintains an up-to-date record of the relevant competence, academic and professional qualifications, training, and experience of all staff concerned with calibrations and tests. These records are held by the HR Department of Guy’s and St Thomas’ Hospital Trust, accessible to the Head of Clinical Scientific Computing.
-
Records specifically related to the training and experience in calibrations are held by the QMO/Quality Representatives in the CSC-I-003 Authorisation Log within the CSC QMS.
-
Job descriptions of all core CSC Department staff are held by the Head of Clinical Scientific Computing in the Trust HR portal.
