The Joint Strategic Needs Assessment (JSNA) identifies current and future health and wellbeing needs in a local population based on existing services and evidence of effectiveness. It provides a comprehensive picture of needs and inequalities. The JSNA involves project boards and is intended to be accessible, user-friendly, and linked to strategic initiatives and feedback. It produces executive summaries, key priorities, findings, and detailed reports for professional and strategic planning. Local developments since 2009 include refreshing core datasets and adding new chapters. In the future, GP consortia and local authorities will have a shared obligation to prepare the JSNA through health and wellbeing boards to understand needs and agree shared priorities and strategies across organizations.
