The SIGN Decision Support app and website aim to support health and social care practitioners across Scotland to make safe, effective, timely decisions based on SIGN guidance in day to day frontline practice.   The SIGN Decision Support platform is designed to bridge the gap between knowledge and action by delivering a suite of decision support toolkits based on individual SIGN guidance and evidence products.

Organisations involved in this app/website

SIGN (Scottish Intercollegiate Guidelines Network):   SIGN was formed in 1993. Its objective is to improve the quality of health care for patients in Scotland by reducing variation in practice and outcome, through the development and dissemination of national clinical guidelines containing recommendations for effective practice based on current evidence.

The membership of SIGN includes all the medical specialties, nursing, pharmacy, dentistry, professions allied to medicine, patients, health service managers, social services, and researchers. The work of SIGN is supported by an Executive.

SIGN is part of the Evidence Directorate of Healthcare Improvement Scotland and core funding from Healthcare Improvement Scotland supports the SIGN Executive, and expenses and costs associated with guideline development projects. SIGN is editorially independent from Healthcare Improvement Scotland and the Scottish Government which ultimately funds Healthcare Improvement Scotland.

Digital Health and Care Institute (DHI): The Digital Health and Care Institute is a health and care innovation centre based in the University of Strathclyde. It is funded jointly by Scottish Government Digital Health and Care and the Scottish Funding Council. DHI plays a pivotal role in inspiring, enabling and combining industry and academic expertise with service, business and technical innovation to create person-centred digital health and care innovations. DHI focuses on shifting the balance of care from a traditional treatment model, through the development of digital health and care innovations that focus on prevention, early detection, post event care and independent assisted living.

DHI leads and manages the national Decision Support Programme on behalf of Scottish Government, as a core objective within Scotland’s Digital Health and Care Strategy. The app and website have been built using the Right Decision Service tools which DHI has developed as a key deliverable for the national programme.
