Harvey Walsh receives health data under licence from NHS Digital. NHS Digital has a record of all hospital admissions and outcomes, the Hospital Episode Statistics (HES) dataset. This data is provided to us every month. The data we use is pseudonymised and non-identifiable, meaning that individuals cannot be identified from the data. These data are processed solely for the purposes of understanding and improving outcomes for patients, and the provision of healthcare, on behalf of the NHS and the medical device and pharmaceutical industries. We never give direct access to unprocessed HES data; rather we aggregate data at an organisational level, and then provide insights and build analytical tools. The data is held securely at a location that conforms to both ISO27001 and NHS Information Governance Toolkit standards, and is destroyed appropriately when required.
