Ageing and Alcohol: Outcomes and Opportunities for Improved Care in Older Populations

Abstract Background Alcohol-related health issues in older adults represent a significant yet often under recognised burden on healthcare services. This study explores the impact of alcohol-related hospital admissions in adults aged 75 and older, focusing on resource utilisation, clinical outcomes, and discharge destinations across 34 acute hospitals in the Republic of Ireland over a five-year period. Methods This was a retrospective, observational study. Using the National NQAIS Clinical data tool, data were collected on adults aged 75 and above with a primary discharge diagnosis relating to alcohol-related morbidity, discharged between December 2019 and December 2024, with N=716 patient discharges identified. Key metrics included length of stay (LOS), mortality, ICU utilisation, allied health involvement, readmission rates, and discharge destinations. Results Of the 716 patient episodes examined, mean length of stay was 15.9 days, with an in-hospital bed day usage of 11,396. An in-hospital mortality rate of 5.4% was recorded among these patients. Similarly, 3.4% required ICU admission, accounting for 110 ICU bed days. A 30-day readmission rate of 16.2% was recorded in the 716 patient episodes, with 4.6% readmitting within 7 days. 17.0% of patients were discharged to nursing homes. Patients discharged to nursing homes had significantly longer LOS (37.7 vs. 11.5 days) and higher comorbidity scores. Conclusion Alcohol-related admissions in older patients impose a substantial burden on acute hospital resources, with prolonged hospital stays, high allied health needs, and significant rates of nursing home discharge. This study reflects that alcohol excess is a significant issue in the older population, as this study only delves into admission wherein alcohol was primary issue on admission. Consideration for alcohol-specific service provision (which have proven beneficial in other cohorts) on the Geriatric ward could have a positive impact on patient outcomes.
