Abstract Introduction Frailty assessment in stroke is not commonly integrated into clinical practice, despite current clinical recommendations. Pre-stroke frailty is associated with longer-term mortality, length of admission, and disability. Similarly, anticholinergic burden (ACB) is not routinely reviewed, even though it is associated with cognitive and physical impairment, increased hospital admissions, and higher mortality in older people. Healthcare Improvement Scotland-Frailty (HIS-Frailty) is a novel tool for the evaluation of frailty in older people. Our aim was to compare and correlate the identification and severity of frailty with HIS-Frailty to the Rockwood Clinical Frailty Scale (CFS) in stroke. We also used the ACB Score to determine if there was a difference in ACB between hospital admission and discharge in these patients. Methods We conducted a prospective, observational, single-centre study in a stroke unit. Patients with a cerebrovascular diagnosis were included. We compared frailty assessment through linear correlation and ACB through mean difference in scores. Results were considered statistically significant if p-value < 0.05 and highly statistically significant if p-value < 0.005. SPSS® 26.0 was used to perform data analysis. We included 145 patients. 110 (76%) were older than 60 years and 75 (52%) were male. Most admissions were due to ischemic stroke (67%), closely followed by TIA (14%). Forty-eight (32%) were classified as frail. There was a strong positive correlation between HIS-Frailty and the CFS (r = 0.95; p <0.00001; R2 = 0.91). Seventy-nine (55%) patients had significant ACB. There was no significant difference between ACB at admission and discharge (MD = 0.010, CI 95% -0.52 to 0.54; p = 0.97). Conclusion HIS-Frailty may prove to be a consistent and easy tool for the systematic identification of frailty in stroke patients, in accordance with best clinical practice guidelines. We should identify and standardise measures to reduce ACB after admission for stroke.
