FAQs
Does Akrivia Health sell the patient data to pharmaceutical companies to run drug trials?
The data is not sold as we operate a data services model. Registered Network individuals can work with de-identified aggregated data by using the analytics platform. To protect privacy, it is not possible for individuals or small groups of individuals to be identified. However, one of the intended uses of the data is to improve the efficiency of drug trials to speed up access to new drugs for patients at a lower cost.
Do all patients make their data available if their hospital is a Healthcare Partner?
All patients reserve the right to opt out of the data processing by contacting the hospital that they are receiving treatment and care from. We adhere to all relevant statutory requirements relating to processing data in the UK
Where is the data being stored?
All data is stored in electronic format by the individual hospital from which the patient receives treatment or care. Each hospital will be the Data Controller for that individual’s data. Data is extracted from each hospital’s patient management system under a contractual agreement with each trust and securely stored by Amazon Web Services (AWS) on behalf of Cristal Health Limited (branded as Akrivia Health) who is the Data Processor.
What data standards are being used to ensure the data is kept safe?
We use a robust information governance model to safely manage data and protect individual privacy. Any suppliers engaged will need to demonstrate that they meet all appropriate industry standards and certification as required by the NHS, ICO and EDPB e.g. ISO 27001. Additional boards will be added to the governance model to ensure there is appropriate oversight and that stakeholder views are represented.
What can you do with the data?
Registered Network individuals can work with the de-identified aggregated data by using the analytics platform. Akrivia Health is currently developing pre-defined algorithms and tools to be able to query the structured and unstructured data. Results will be provided on an aggregated basis to protect individuals’ privacy.
In addition, Akrivia Health can provide consulting support to determine more complex models to be generated.
Are patients involved in the business as it is their data?
We actively encourage advice and feedback from patient and public groups on its work. Where appropriate, patient representatives are appointed onto Governance structures that are established. As part of our Corporate Social Responsibility plans, we will measure and report on the actual impact that we have for patients.
