ABSTRACT
BACKGROUND: Elderly patients with acute coronary syndromes (ACS) are at higher risk for complications and health care resources expenditure. No previous study has assessed the specific contribution of frailty and other geriatric syndromes to the in-hospital economic cost in this setting.
METHOD: Unselected patients with ACS aged ≥75 years were prospectively included. A comprehensive geriatric assessment was performed during hospitalisation. Hospitalisation-related cost per patient was calculated with an analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in Euros (2019). The contribution of geriatric syndromes and clinical factors to the economic cost was assessed with a linear regression method.
RESULTS: A total of 194 patients (mean age 82.6 years) were included. Mean length of hospital stay was 11.3 days. The admission-related economic cost was €6,892.15 per patient. Most of this cost was attributable to hospital length of stay (77%). The performance of an invasive strategy during the admission was associated with economic cost (p=0.008). Of all the ageing-related variables, comorbidity showed the most significant association with economic cost (p=0.009). Comorbidity, disability, nutritional risk, and frailty were associated with the hospital length of stay-related component of the economic cost. The final predictive model of economic cost included age, previous heart failure, systolic blood pressure, Killip class at admission, left main disease, and Charlson index.
CONCLUSIONS: Management of ACS in elderly patients is associated with a significant economic cost, mostly due to hospital length of stay. Comorbidity mostly contributes to in-hospital resources expenditure, as well as the severity of the coronary event.
