The NHS complaints procedure is the statutorily based mechanism for dealing with complaints about NHS care and treatment and all NHS organisations in England are required to operate the procedure. This annual collection is a count of written complaints made by (or on behalf of) patients, received between 1 April 2009 and 31 March 2010.
