Public Health Privacy Notice
All local authorities have a duty to improve the health of the population they serve. To help us do this, we use data from a range of sources including the Office for National Statistics, the Health and Social Care Information Centre, Bexley Clinical Commissioning Group and hospitals to understand more about the nature and causes of disease and ill health in Bexley.
The Public Health team at the London Borough of Bexley also have a legal status allowing the processing of personal confidential data for certain public health purposes. The statutory responsibilities for public health services are clearly set out in the Health and Social Care Act 2012. Bexley Council is registered with the Information Commissioners Office (ICO) under the provisions of the Data Protection Act 2018. Any personal information we hold is collected and processed in accordance with the requirements of the Data Protection Act 2018, EU General Data Protection Regulation (GDPR) and the Caldicott Principles.
This Privacy Notice should be read in addition to the Bexley Council Corporate Privacy Notice and gives more details about how personal information is collected to improve the health of Bexley residents.
Who do we collect information about?
Bexley Council collects and holds information for public health purposes about all to whom it has a public health duty of care which includes:
- residents of Bexley
- people receiving preventative, health, and social care services in Bexley
- people who work or attend school in Bexley
What personal information do we process?
We work with many types of data to be able to promote health and support improvements in the delivery of health and care services in Bexley. Broadly these can be described as:
- Special Category data – personal data which is more sensitive including race, ethnic origin, politics, religion, trade union membership, genetics, biometrics (where used for ID purposes), health, sex life or sexual orientation. Depending on the service, the provider may require information about your health or other data which is classed as sensitive. Further information can be found in the Data Protection Act 2018
- Identifiable data – this is personal data that can identify individuals such as name, date of birth, gender, address, postcode and NHS number. Personal information includes expressions of opinion about an individual or any indications of intention in respect of the individual
- Pseudonymised data – this contains information about individuals but with the identifiable details replaced with a unique code. The purpose is to render the data record less identifying and therefore lower customer or patient objections to its use
- Anonymised data – all identifying details are anonymised so individuals cannot be identified
- Aggregated data – data that has been grouped together so that it does not provide information on individuals, only groups of people
Bexley Council Public Health is committed to using pseudonymised or anonymised information as much as is practical, and in many cases, this will be the default position.
What is the purpose of processing your personal information?
Bexley Council Public Health uses personal identifiable information about residents and users of health care, to enable it to carry out specific functions for which it is responsible, such as:
- control of infection and health protection activities
- management of risks to public health
- organising the National Child Measurement Programme
- organising the NHS Health Check Programme
- organising and supporting the 0 to 19 Children’s Public Health Service (Health visiting and school nursing)
- contract monitoring of adult weight management service to satisfy eligibility is met
- improving health outcomes, evaluating the quality of services and patient experience
Bexley Council Public Health also uses information about residents and users of health care to derive statistics and intelligence for research and planning purposes. In these cases, personal identifiable details are removed as soon as is possible in the processing of intelligence so that individuals cannot be identified from them.
This enables Bexley Council Public Health to carry out specific functions for which it is responsible, such as:
- producing assessments of the health and care needs of the population, in particular, to support the statutory responsibilities of the:
- Joint Strategic Needs Assessment (JSNA)
- Director of Public Health Annual report
- Health and Wellbeing Strategy
- identifying priorities for action
- informing decisions on, for example, the design and commissioning of services
- to assess the performance of the local health and care system and to evaluate and develop them
- to report summary statistics to national organisations
- undertaking equity analysis of trends, particularly for vulnerable groups
- to support clinical audits
What are the lawful bases for processing your personal information?
In order to fulfil the local authority public health responsibilities set out in the Health and Social Care Act 2012, Bexley Council has a legal basis to process personal confidential data for certain public health purposes:
- GDPR Article 6(1)(e) Lawfulness of processing - to allow us to perform a public task carried out in the public interest or in the exercise of official authority vested in the controller
- GDPR Article 9(2)(i) Processing of special categories of personal data - for reasons of public interest in the area of public health, such as protecting against serious cross-border threats to health or ensuring high standards of quality and safety of health care and of medicinal products or medical devices, on the basis of Union or Member State law which provides for suitable and specific measures to safeguard the rights and freedoms of the data subject, in particular professional secrecy
Information may also be provided directly by you as members of the public to The Council when you sign up to use a service. This is collected in appropriate systems and used to provide or administrate that service. These systems are access controlled, so only relevant employees have access to them. With consent, we may also make referrals to other services, such as a GP from these systems.
If the legal basis for processing is explicit consent, we will need to ensure you are provided with a:
- clear explanation of exactly what is being consented to
- clear “opt-in”
- clear option to withdraw your consent later by use of an “opt-out”
