The Interplay between Anticholinergic Burden and Anemia in Relation to 1-Year Mortality among Older Patients Discharged from Acute Care Hospitals

Anticholinergic burden in older adults with psychiatric illnesses: A cross-sectional study

OBJECTIVES

We aimed in this study to determine the extent of exposure to anticholinergic drugs in older adults with psychiatric illnesses using the anticholinergic cognitive burden (ACB) scale and to identify the factors associated with anticholinergic drugs use and higher ACB scores.

METHODS

A cross-sectional study was conducted in the psychogeriatric division of an elderly care hospital. The study sample comprised all inpatients, aged ≥65 years, and diagnosed with psychiatric illness.

RESULTS

Anticholinergic drugs use was reported in 117 (79.6 %) patients, 76 (51.7 %) had an ACB score ≥ 3. Schizophrenia [OR = 5.4 (95 % CI 1.1-10.2), p = 0.02], anemia [OR = 2.2 (95 % CI 1.54-7.89), p = 0.01], and anticholinergic adverse effects [OR = 2.8 (95 % CI 1.12-7.07), p = 0.04] were significantly associated with a higher likelihood of using anticholinergic drugs. The odds of having an ACB score ≥ 3 over an ACB score = 0 were significantly increased by schizophrenia [OR = 4.9 (95 % CI 1.65-8.02), p = 0.01], anemia [OR = 1.32 (95 % CI 1.90-6.90), p = 0.02], and polypharmacy [OR = 1.74 (95 % CI 1.10-2.40), p = 0.04], while they were significantly decreased by age [OR = 0.86 (95 % CI 0.78-0.96), p < 0.001]. Patients with cognitive impairment were less likely than those without cognitive impairment to have an ACB score ≥ 3 over an ACB score = 0.

CONCLUSIONS

Our study revealed that older adults with psychiatric illnesses were exposed to high anticholinergic burden.
