Mortality in residential care facilities for people with disability: a descriptive cross-sectional analysis of statutory notifications in Ireland

Abstract

ObjectivesTo determine incidence of death in residential care facilities for people with disability in Ireland, primary cause of death, associations of facility characteristics and deaths, and to compare characteristics of deaths reported as expected and unexpected.DesignDescriptive cross-sectional study.SettingAll residential care facilities for people with disability operational in Ireland in 2019 and 2020 (n=1356).Participantsn=9483 beds.Main outcome measuresAll expected and unexpected deaths notified to the social services regulator. Cause of death as reported by the facility.Results395 death notifications were received in 2019 (n=189) and 2020 (n=206). 45% (n=178) were for unexpected deaths. Incidence of death per 1000 beds per year was 20.83 for all, 11.44 for expected and 9.39 for unexpected deaths. Respiratory disease was the most common cause of death, accounting for 38% (n=151) of all deaths. In adjusted negative binomial regression analysis, congregated settings versus non-congregated (incidence rate ratio (95% CI): 2.59 (1.80 to 3.73)) and higher bed numbers (highest vs lowest quartile) (4.02 (2.19 to 7.40)) were positively associated with mortality. There was also a positive n-shaped association with category of nursing staff-to-resident ratio when compared with zero nurses. Emergency services were contacted for 6% of expected deaths. Of the deaths reported as unexpected, 29% were receiving palliative care and 10.8% had a terminal illness.ConclusionAlthough incidence of death was low, residents of congregated and larger settings had higher incidence of death than residents of other settings. This should be a consideration for practice and policy. Given the high contribution of respiratory diseases to deaths and the potential avoidability of these, there is a need for improved respiratory health management in this population. Nearly half of all deaths were reported as unexpected; however, overlap in the characteristics of expected and unexpected deaths highlights the need for clearer definitions.
