Joint Strategic Needs Assessment

JSNAs for Westminster & Kensington and Chelsea

Doing a JSNA

New JSNAs are developed on a regular basis. If you want to conduct a JSNA, please contact us.


The local Health and Wellbeing Boards have established a JSNA Steering Group to determine priorities for the JSNA programme. Each time a JSNA project is started, a 'Task and Finish' group, or working group, is set up, including local partners that will contribute to the project. The project brings together existing local information and sometimes involves new research. Recommendations are made to commissioners. The final report is signed off by the Health and Wellbeing Boards and published on this website.

What is a JSNA?

JSNAs need to meet four critieria: they (1) support a commissioning priority, (2) focus on specific populations / risk factors / diseases / interventions, (3) address knowledge gaps, and (4) provide tangible recommendations for commissioners.

1. Supports a commissioning priority

2. Focuses on specific populations, risk factors, diseases or interventions

3. Addresses knowledge gaps with specific research questions

4. Provides tangible recommendations for commissioners

For example:

  • Supporting people that have a common long term condition with increasing prevalance
  • Providing a targeted service for a small group of patients with high needs


For example:


  • Early years
  • Rough sleepers
  • Gangs

Risk Factors

  • Vitamin D deficiency
  • Paan chewing
  • Substance misuse


  • TB
  • Hepatitis C
  • Suicide


  • Employment support
  • Physical activity


For example:

  • How does prevalence of a disorder vary across The Triborough?
  • What are the demographic patterns in service use?
  • What evidence is there of the effictiveness of alternative interventions and service models?

For example:

  • Invest in a new intervention
  • Reconfigure existing services
  • Move location of services


What should a JSNA include?

JSNAs pull together information on the health and wellbeing of our local population and analyses it in detail. They answer the following questions:

  • What do people need now and in the future?
  • What are the local services and community assets?
  • What evidence is there for the effectiveness of services and interventions?
  • What are the views and priorities of service users?
  • What are the implications for commissioners?
