Mortality rates in teaching hospital complex care wards in England: a retrospective audit

Existing data examining mortality rates following inpatient hospital admissions in the UK are either condition specific or examining all inpatient mortality based on single time point audits. This clinical effectiveness project aimed to assess mortality rates in patients admitted to complex care (CC) wards managed by geriatricians at Southmead hospital, Bristol.

Data were collected by the trust's audit department and analysed by the authors. All patients admitted to the four CC wards from July to December 2017 were included. Data collected included age, gender, date of admission, length of stay, date of discharge and date of death if applicable.

2673 patients were admitted to CC wards from July to December 2017. 42.72% of patients were men, and mean age of patients was 82.46 years. Mean length of stay was 16.68 days. 292 (10.92%) of patients died during the index admission. Overall mortality rates were: (1) 1 month: 11.34% (303 patients); (2) 3 months: 21.59% (577 patients); (3) 6 months: 30.15% (806 patients); (4) 12 months: 38.53% (1030 patients). 12-month mortality increased with age from 75 upwards (34.04% in 75-79 years, 42.94% in 85-89 years, 50.27% in 95-99 years, 66.67% in 100-104 years) but was similar in those aged 65-69 and 70-74 years (29.41% and 28.18%, respectively).

An improved understanding of mortality rates in patients requiring an admission under geriatricians may aid clinicians' ability to prognosticate. Appreciating that over a third of these patients are potentially in the last year of life provides further impetus to begin advance care planning discussions during inpatient admissions.
