Summary Background Benzodiazepines (BZD) are associated with adverse effects, particularly in older adults. Aim This study assesses the association between BZD use and falls, and the impact of sleep quality on this association, in community dwelling adults aged over 50. Design Cross-sectional analysis of data from wave 1 of The Irish Longitudinal Study on Ageing. Methods Participants were classed as BZD users or non-users and asked if they had fallen in the last year, and whether any falls were unexplained. Sleep quality was assessed via self-reported trouble falling asleep, daytime somnolence and early-rising. Logistic regression assessed for an association between BZD use and falls, and the impact of sleep quality on this association was assessed by categorizing based on BZD use and sleep quality variables. Results Of 8175 individuals, 302 (3.69%) reported taking BZDs. BZD use was associated with falls, controlling for confounders [Odds Ratio (OR) 1.40; 1.08, 1.82; P-value 0.012]. There was no significant association between BZDs and unexplained falls, controlling for confounders [OR 1.41; 95% Confidence Interval (CI) 0.95, 2.10; P-value 0.09]. Participants who use BZDs and report daytime somnolence (OR 1.93; 95% CI 1.12, 3.31; P-value 0.017), early-rising (OR 1.93; 95% CI 1.20, 3.11; P-value 0.007) or trouble falling asleep (OR 1.83; 95% CI 1.12, 2.97; P-value 0.015), have an increased odds of unexplained falls. Conclusion BZD use is associated with falls, with larger effect size in those reporting poor sleep quality in community dwelling older adults. Appropriate prescription of medications such as BZDs is an important public health issue.

Background: Reduced and delayed presentations for non-COVID-19 illness during the COVID-19 pandemic have implications for population health and health systems. The aim of this study is to quantify and characterise changes in acute hospital healthcare utilisation in Ireland during the first wave of COVID-19 to inform healthcare system planning and recovery. Methods: A retrospective, population-based, interrupted time-trend study was conducted using two national datasets, Patient Experience Time (PET) and Hospital In-Patient Enquiry (HIPE). The study period was 6th January to 5th July 2020. Results: Comparison between time periods pre- and post-onset of the COVID-19 pandemic within 2020 showed there were 81,712 fewer Emergency Department (ED) presentations (-18.8%), 19,692 fewer admissions from ED (-17.4%) and 210,357 fewer non-COVID-19 hospital admissions (-35.0%) than expected based on pre-COVID-19 activity. Reductions were greatest at the peak of population-level restrictions, at extremes of age and for elective admissions. In the period immediately following the first wave, acute hospital healthcare utilisation remained below pre-COVID-19 levels, however, there were increases in emergency alcohol-related admissions (Rate Ratio 1.22, 95% CI 1.03, 1.43, p-value 0.016), admissions with self-harm (Rate Ratio 1.39, 95% CI 1.01, 1.91, p-value 0.043) and mental health admissions (Rate Ratio 1.28, 95% CI 1.03, 1.60, p-value 0.028). Discussion: While public health implications of delayed and lost care will only become fully apparent over time, recovery planning must begin immediately. In the short-term, backlogs in care need to be managed and population health impacts of COVID-19 and associated restrictions, particularly in relation to mental health and alcohol, need to be addressed through strong public health and health system responses. In the long-term, COVID-19 highlights health system weakness and is an opportunity to progress health system reform to deliver a universal, high-quality, sustainable and resilient health system, capable of meeting population health needs and responding to future pandemics.
