Mortality rate and palliative sedation in an acute palliative care unit

Abstract

AimTo assess the mortality rate and the use of palliative sedation (PS) in an advanced long-standing acute palliative care unit (APCU)MethodsThe charts of patients who died and eventually received PS, consecutively admitted to the APCU for 4 years, were reviewed. Patients' characteristics and symptom intensity were recorded at admission, 3 days before death and the day before death (T0, T-3, T-end, respectively). For patients who were administered midazolam for PS, initial and final doses of drugs, as well as duration of PS until death, were recorded.ResultsOne hundred and forty-eight patients died in APCU (8.9%), and 45 of them (30.4%) received PS. Younger patients and those reporting high levels of dyspnoea at T-3 and T-end were more likely to be sedated (p=0.002, p=0.013 and 0.002, respectively). The mean duration of PS was 27.47 hours. Mean initial and final doses of midazolam were 35.45 mg/day (SD 19.7) and 45.57 mg/day (SD 20.6), respectively (p=0.001).ConclusionMortality rate in APCU was very low. As a percentage of the number of deaths, PS rate was similar to that reported in other settings. PS does not seem to accelerate impending death.
