Hospital Abbreviations
89 abbreviations · part of Medical Abbreviations
Hospital abbreviations name the units, departments, facility types, roles and safety programs that patients and staff encounter, from the ICU, ED and PACU to post-acute settings such as SNFs, LTACHs and IRFs. Many facility types (CAH, FQHC, SNF, IRF) are defined by US Medicare and Medicaid rules that set what services they provide and how they are paid, while unit names vary between hospitals. Infection-control and quality abbreviations such as CLABSI, CAUTI and HCAHPS refer to nationally tracked measures that affect hospital ratings and payment.
