The Commission for Patient and Public Involvement in Health (CPPIH) was an independent, non-departmental public body sponsored by the UK Department of Health. The Commission was established by and act of Parliament on 10 December 2002 with a remit "to establish a new system of patient and public involvement in health for England involving traditionally hard to reach groups" – however, there was no agreed budget or management structure in place at that time. The Commission operated from September 2003 until March 2008 when it was replaced with local involvement networks (LINks), involvement mechanisms that extend public involvement to health and social care.
