Abstract

Background/objective The impact of medications with anti-cholinergic properties on morbidity and mortality of unselected adult patients admitted to the emergency general surgical setting has not been investigated. Methods All cases were identified prospectively from unselected adult patients admitted to the emergency general surgical ward between May to July 2016 in a UK centre with a catchment population circa 500,000. Prescribed medication lists were ascertained from case notes and electronic medical records. Anti-Cholinergic Burden (ACB) was calculated from medication lists. Patients were categorised into three groups based on ACB; none (ACB score of 0); moderate (up to ACB score of two); high (ACB score more than two). The effect of increasing ACB on selected outcomes of 30- and 90-day mortality, hospital readmission within 30-days of discharge and increased length of hospital stay were examined using multivariable logistic regression models. Results The 452 patients had a mean age (SD) of 51.7 (±20.6) years, 273 (60.4%) patients had no ACB burden, 106 (23.5%) had a ACB burden of up to two; and 73 (16.2%) had an ACB burden of > 2. Multivariable analyses showed no association between high ACB burden and 90-day (fully adjusted odds ratio [OR] 0.56 (95%CI 0.12–2.85); P = 0.48) and 30-day mortality (fully adjusted OR = 0.75 (95%CI 0.05–11.04); P = 0.84). A significant association was observed between moderate ACB burden and 30-day hospital readmission (fully adjusted OR = 2.01 (95%CI 1.09–3.71); P = 0.03). Conclusions Anti-cholinergic burden may be linked to hospital readmission in adults admitted to an emergency general surgical ward.
