Public Health privacy notice

This privacy notice covers the Public Health directorate which sits within Strategic Policy, Planning and Performance, a Division of the Cabinet Office.

Strategic Policy, Planning and Performance is registered as a 'Controller' under the Data Protection (Jersey) Law 2018 (the “Data Protection Law”), as we determine the purpose and means of the processing of the personal information collected about you for this service. 

Public Health refers to services designed to help the population stay healthy and avoid disease. This covers a range of policy areas, from preventing substance abuse to improving nutrition and delivering vaccinations. 

The information collected by the directorate enables us to understand more about the nature and causes of disease and ill health in Jersey by measuring the health, mortality and care needs of the population, as well as the diseases and our way of life. This allows us to plan and evaluate services, and to undertake Public Health surveillance to ensure that services and interventions are effective and working for the benefit of the population by improving or protecting public health.

Public Health is also responsible for delivering several services directly to the public, and commissioning other providers to deliver services on behalf of public health. This includes school age vaccinations and interventions which support healthy approaches to food and nutrition in schools.

As a government directorate, Public Health process and hold your information to provide these public services and meet our statutory obligations. This notice explains in more detail how Public Health use and share your information to provide the services or interventions described below.

Public Health will only publish information in a form that does not identify individuals or households. 

Public Health will only publish data which has been aggregated (grouped), routinely suppressing (hiding) numbers fewer than five and ensuring that such figures cannot be obtained by differencing (adding and subtracting other figures to work out the missing one).

Records will not be linked in different datasets for example, hospital and mortality files, unless given express permission to do so.

How long we store your information

Statistical information usually relates to a particular point in time so does not need to be updated. 

Public Health will only keep hold of your information for as long as is necessary. This will depend on what the specific information is and the agreed period. The data is permanently disposed of after this period, in line with Public Healths records retention policy or the specific requirements of the relevant data sharing agreement. These arrangements are regularly reviewed as part of Information Governance.

Where we store your information

Government of Jersey systems store data in Jersey, the UK and the European Union. The UK has been granted adequacy status by the European Commission and personal data stored there will be protected to the same standards as personal data held in Jersey and the EU. 

Personal confidential data will only be processed by Public Health employees in fulfilment of their public health functions. All staff have contractual obligations of confidentiality and must attend training in Information Governance. Amongst other things, this training makes them understand the importance of confidentiality and security of your personal data and makes clear that they are personally responsible for the security of any information which they are processing. The expectations on staff are set out in the Information Governance Policy.

Relevant organisational and technical measures are taken to ensure the information held is secure, such as using secure locations, restricting access to authorised personnel and protecting personal and confidential information held on computers with encryption. Personal confidential information is only exchanged using secure methods, such as encrypted email or through secure encrypted data file transfers (SEFT). 

Where practical, Public Health will anonymise your data. In this case, it will cease to be personal data and may be retained indefinitely.

During qualitative interviews, participant data is captured during the discussions. Any personally Identifiable Information will be redacted from the recording or transcript before being passed to anyone outside the department. This extends to ensuring that no visual personal information from the environment is picked up on photos, or video.

All data storage is encrypted and secure. Access is limited to password holders and scheduled to end on a specified date. The location of all data relating to individual participants is required to be logged, and a deletion date set, including emails arranging the face to face interviews or focus group.

Analysts utilise Nvivo, a qualitative data analysis (QDA) computer software package. NVivo helps organise, analyse and find insights in unstructured or qualitative data like interviews, open-ended survey responses, journal articles, social media and web content, where deep levels of analysis on small or large volumes of data are required. All identifiable, pseudonymised and sensitive datasets from this software are stored electronically on secure government of Jersey servers which can only be accessed by public health professionals.

SmartSurvey servers are based in the UK. No one will access your data unless they have the credentials to access your account, Public Health publish the data, or SmartSurvey staff for the purposes of providing support or fixing a technical issue. SmartSurvey staff are all UK based.
