high mortality outlier
Definition A popular term for a hospital or medical centre identified by a regulatory or oversight body (CMS/HCFA, USA; NHS, UK) as having a mortality rate far in excess of the regional norm for other (±5500) healthcare facilities in the country in which the data is collated.
Comment Outliers may be due to characteristics of the patient population–e.g., elderly–older than 85, “high-risk” diagnoses or skewing of data by those who require nursing care upon discharge. Mortality rates may thus be of little use in determining patient quality of care.
