Aim To evaluate the anticholinergic burden (ACB), the risk factors associated with its onset and the clinical consequences for patients with advanced chronic conditions. Methods A 10‐month cross‐sectional study was carried out in an acute hospital care geriatric unit. Patients with advanced chronic conditions were identified by the NECessity of PALliative care (NECPAL) test. The ACB was established using the Anticholinergic Drug Scale and Drug Burden Index (DBI) tools. Demographic, pharmacological and clinical patient data were collected with the objective of determining risk factors related to ACB. Measured clinical outcomes were the presence of acute confusional state, bone fractures, length of stay, mortality and 12‐month survival rate. Results A total of 235 patients were recruited (mean age 86.80 years, SD 5.37 years; 65.50% women), and 82.10% (DBI) and 93.6% (Anticholinergic Drug Scale) of the patients were treated with anticholinergic medications. Excessive polypharmacy (≥10 drugs) was identified as a risk factor for the presence of anticholinergic medication (Anticholinergic Drug Scale: OR 6.26, 95% CI 1.38–28.42; DBI: OR 3.44, 95% CI 1.60–7.38). High anticholinergic burden (by DBI >2 points) was an independent risk factor for the presence of acute confusional state on hospital admission (OR 2.98, 95% CI 1.04–8.50). However, ACB was not related to bone fractures on admission, length of stay, mortality or survival. Conclusions Patients with advanced chronic conditions are frequently treated with anticholinergic drugs, with excessive polypharmacy as a risk factor. Anticholinergic drugs are a risk factor for the presence of acute confusional state on hospital admission, but have no other effect in terms of morbimortality.
