  • Use mapping to deliver services and improve patient care

    The PSMA and OSMA give you access to a range of premium datasets that enable you to plan and deliver more effectively.

    Join today

Ordnance Survey is committed to helping the health sector benefit from using geographic information available to the NHS and Local Authorities through the Public Sector Mapping Agreement (PSMA).

Our data is being used today right across the health sector to help develop policy, plan and deliver services and monitor their success. Our data is delivering real benefits in terms of efficiency gains, optimisation and access to services and health gains for our citizens. Over 200 NHS organisations are already taking advantage of these outcomes.

Health organisations that benefit from the PSMA include:

  • Department of Health
  • NHS England
  • Public Health England
  • Health and Social Care Information Centre
  • Clinical Commissioning Groups (CCG's)
  • Commissioning Support Units (CSU's) - under the Standard Contractor Licence
  • NHS Hospital Trusts
  • All Local Authorities

NHS transition

The changes taking place to the NHS may impact how your organisation is licensed under the PSMA. Please see the sections below to understand the different scenarios that may apply:

Your mapping function is moving to a newly formed Clinical Commissioning Group (CCG)

These bodies are eligible for membership in the PSMA. They will need to have an account set up in order to take advantage of PSMA membership and can apply to set up that account. You can check if your CCG is already a member and download a full member list.

Your mapping function is moving to local government

You will in this instance be covered by the respective local authority / public body’s PSMA membership. This will entitle you to exactly the same level of mapping access and usage as your previous PSMA membership. All local authorities in England are members of the PSMA.

Your mapping function is moving to a Commissioning Support Unit (CSU)

CSUs are not eligible for membership of the PSMA in their own right; however these organisations will be able to support CCGs with mapping services under the PSMA licence. We have agreed two licensing options for CSUs with NHS England:

NOTE: as CCGs are the beneficiary and licensee of the PSMA, for both of these options a CSU’s respective CCGs must join the PSMA before a CSU can use PSMA data on their behalf.

Option one: CCGs nominate their CSU as a PSMA contractor

CCGs are entitled to share PSMA data with any organisation working on their behalf, including CSUs. Under a contractor licence, your customer has to be licensed directly to us for the data that they want you to use on their behalf. Once your customer has their licence, they can provide you with a Contractor Licence which will allow you access to their data. Note: under this licence you are only permitted to use the data for the work that your customer has asked you to do. Once you have completed the work you will have to return the data to your customer; you will not be permitted to use/keep the data for any other purpose.

Where a CSU provides mapping services to multiple CCGs, As an alternative to our Standard Contractor Licence, you may find our Distribution Contract under Framework Contract (Partners) more suitable if you wish to provide services, requiring the use of our data, to multiple customers on a regular basis. Whilst your customer will still need their own OS Licence, under this contract you will be able to use your own copy of OS Data rather than having to request separate copies from each of your customers. Note there is a fee associated with this licence. Please contact partnership enquiries for further information.

Option two: CSU accesses PSMA as part of NHS England

NHS England and Ordnance Survey have agreed that CSUs can now access PSMA mapping through the NHS England licence. CSUs are able to licence their mapping from NHS England, and under the PSMA principles of data sharing between members, freely share the mapping with their respective CCGs. A CSU would still be required to ensure their respective CCGs become members of the PSMA (as they are the organisations gaining operational benefit from the PSMA), but the CSU would not need to act as a contractor to or receive mapping from a CCG.

They are able to licence their mapping from NHS England, and under the PSMA principles of data sharing between members, freely share the mapping with their respective CCGs.

How does the NHS use Ordnance Survey mapping?

Ordnance Survey’s geographic information is used across the whole spectrum of NHS organisations, from estate management and emergency response to mapping demographic changes and optimising service locations. These are some example of how the NHS benefits from the PSMA:

  • Visualising complex information to aid shared decision making e.g. planning health services in Bromley
  • Planning effective delivery of services and contract monitoring e.g. pinpointing patients and practice areas (South West Commissioning Support)
  • Optimising service locations by mapping population needs e.g. improving drug and alcohol treatment provision in Bristol (Avon IMT)
  • Identifying gaps in service provision e.g. improving primary care out-of-hours services in Somerset (South West Commissioning Support)
  • Effective targeting of resources to areas of greatest need e.g. cutting teenage pregnancy rates in Hull (Hull City Council)
  • Provide evidenced-based decision making to improve public health e.g. mapping the way to good health in Birmingham (NHS Birmingham and Solihull & Birmingham City Council)
  • Improving Business Intelligence and marketing e.g. effective planning of patient services in Birmingham (Heart of England NHS Foundation Trust)
  • Mapping the uptake of services e.g. working together to improve childhood immunisation rates (Luton PCT)
  • Streamline health services and improving customer service e.g. simplifying search results and streamline health service staff response times (South West Commissioning Support)
  • Strategic asset and estate planning e.g. helping the NHS get into SHAPE (Strategic Health Asset Planning and Evaluation)
  • Ensuring effective healthcare provision in areas of new development e.g. impact of new housing on primary health facilities (NHS North Essex)
  • Emergency planning and response e.g. improving ambulance services in the North East (North East Ambulance Service)
  • Service redesign and identifying new site locations e.g. why maps are good for your health (NHS West Kent and Medway)

If you work for the NHS and have benefitted from PSMA membership, we would like to hear from you – submit a case study.

Case studies

NHS® staff across the country are being urged to get into SHAPE – a web-enabled, evidence-based application that is built around Ordnance Survey's accurate geographic information, that can radically improve the planning and redesign of health services.

Obesity is a huge problem in the UK. In Birmingham, 29% of the adult population and 25% of 11–12 year olds are obese. Therefore, tackling it is a priority.

After 2003, immunisation uptake statistics for Luton Primary Care Trust (PCT) were reported by individual PCTs, showing that critical information had been masked.

Located in the north-east corner of Scotland, NHS Grampian serves a mixed urban and rural population of 526,000 people. It provides pharmaceutical services across a wide geographic area, whilst addressing the needs of a population living in remote, rural areas as well as urban areas.
