Acute care

Acute care kathschach

Acute care for inpatients in hospital refers to necessary treatment for a disease or severe episode of illness provided for a short period of time. CIHI provides valuable insight on the quality of care, patient experiences, cost, volumes and types of acute care cases admitted to Canadian hospitals. CIHI also facilitates the collection of standardized information on acute care through databases such as the Discharge Abstract Database (DAD) and the Hospital Morbidity Database (HMDB).
