In conjunction with the key stakeholders, the Offender Health (formerly prison health) team has developed a set of voluntary indicators specifically to measure the quality of prison health services and to help achieve the objective of NHS-equivalent standards. The data is collected on a voluntary basis, collated and reported nationally, and is intended to support and inform existing local performance management processes. The Offender Health team has also written a guidance booklet and a covering letter which sets out the rationale for collecting the data. (DH - publications)
