The Commission for Health Improvement (CHI) was set up in 1999 to improve the quality of patient care in the NHS across England and Wales. CHI has completed clinical governance reviews in the majority of acute trusts across the country and is now reviewing mental health, primary care and ambulance trusts. There are 95 trusts in England and Wales that provide mental health services. These include trusts that provide integrated acute and mental health services and primary care trusts, which provide secondary mental health services. CHI aims to complete up to 30 reviews of mental health services each year. To achieve this, they require the skills and knowledge of consultants on their review teams. CHI review teams are multi-disciplinary and mental health reviews usually comprise a consultant psychiatrist, nurse, clinical psychologist, occupational therapist, manager, social care member, lay person and mental health service user. All consultants are encouraged to apply and become CHI reviewers. Your experience is vital to CHI's work, but you would also return to work equipped with even greater skills to improve patient care in your organisation. For more information on becoming a CHI reviewer please contact the reviewer team on tel: 020 7448 9467; or e-mail: reviewer@chi.nhs.uk.
