A system for collecting, compiling, and analyzing summary statistical data from hospital records in order to create quantitative profiles of hospital activities, including length of hospital stay in relation to diagnostic categories, case fatality rates, occurrence of complications, nosocomial infections, etc. Pioneers in the collection and statistical analysis of hospital records include the British nurse Florence Nightingale (1820–1910) and the Hungarian obstetrician Ignaz Philipp Semmelweis (1818–1865). Widely used national systems include the Hospital Inpatient Enquiry (HIPE) in the United Kingdom and the Commission on Professional and Hospital Activities (CPHA) in the United States. Their compiled statistics have many uses, including preparation of clinical practice guidelines and evaluation of the effectiveness and efficiency of hospital care.
