Background: Fall-related hospitalisations from residential aged care services (RACS) are distressing for residents and costly to the healthcare system. Strategies to limit hospitalisations include preventing injurious falls and avoiding hospital transfers when falls occur. Aims: To undertake a root cause analysis (RCA) of fall-related hospitalisations from RACS and identify opportunities for fall prevention and hospital avoidance. Methods: An aggregated RCA of 47 consecutive fall-related hospitalisations for 40 residents over a 12-month period at six South Australian RACS was undertaken. Comprehensive data were extracted from RACS records including nursing progress notes, medical records, medication charts, hospital summaries and incident reports by a nurse clinical auditor and clinical pharmacist. Root cause identification was performed by the research team. A multidisciplinary expert panel recommended strategies for falls prevention and hospital avoidance. Results: Overall, 55.3% of fall-related hospitalisations were among residents with a history of falls. Among all fall-related hospitalisations, at least one high falls risk medication was administered regularly prior to hospitalisation. Potential root causes of falling included medication initiations and dose changes. Root causes for hospital transfers included need for timely access to subsidised medical services or radiology. Strategies identified for avoiding hospitalisations included pharmacy-generated alerts when medications associated with an increased risk of falls are initiated or changed, multidisciplinary audit and feedback of falls risk medication use and access to subsidised mobile imaging services. Conclusions: This aggregate RCA identified a range of strategies to address resident and system-level factors to minimise fall-related hospitalisations. [ABSTRACT FROM AUTHOR]

Aims: The objective of this study is to investigate the association between multiple antihypertensive use and mortality in residents with diagnosed hypertension, and whether dementia and frailty modify this association. Methods: This is a two-year prospective cohort study of 239 residents with diagnosed hypertension receiving antihypertensive therapy across six residential aged care services in South Australia. Data were obtained from electronic medical records, medication charts and validated assessments. The primary outcome was all-cause mortality and the secondary outcome was cardiovascular-related hospitalizations. Inverse probability weighted Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality. Covariates included age, sex, dementia severity, frailty status, Charlson's comorbidity index and cardiovascular comorbidities. Results: The study sample (mean age of 88.1 ± 6.3 years; 79% female) included 70 (29.3%) residents using one antihypertensive and 169 (70.7%) residents using multiple antihypertensives. The crude incidence rates for death were higher in residents using multiple antihypertensives compared with residents using monotherapy (251 and 173/1000 person-years, respectively). After weighting, residents who used multiple antihypertensives had a greater risk of mortality compared with monotherapy (HR 1.40, 95%CI 1.03–1.92). After stratifying by dementia diagnosis and frailty status, the risk only remained significant in residents with diagnosed dementia (HR 1.91, 95%CI 1.20–3.04) and who were most frail (HR 2.52, 95%CI 1.13–5.64). Rate of cardiovascular-related hospitalizations did not differ among residents using multiple compared to monotherapy (rate ratio 0.73, 95%CI 0.32–1.67). Conclusions: Multiple antihypertensive use is associated with an increased risk of mortality in residents with diagnosed hypertension, particularly in residents with dementia and among those who are most frail.
