Different anticholinergic scales.

Score name Princeps publication Country Princeps study population Methods to assess anticholinergic activity Princeps study main results Type of anticholinergic adverse effects: central and peripheral Observations
Anticholinergic Cognitive Burden Scale (ACB) Boustani et al. 2008 [8] USA Older adults attending primary care clinics in Indianapolis (n = 3013) Expert-based list High level of anticholinergic burden. More than 23% of older adults were receiving at least one medication with anticholinergic activity Central One of the most used scale in elderly population
Anticholinergic Risk Scale (ARS) Rudolph et al. 2008 [9] USA Older men adults (≥65 years) attending geriatric at the Veterans Affairs Boston Healthcare System or primary care ambulatory clinics (n = 117) Expert-based list Higher ARS scores are associated with increased risk of anticholinergic adverse effects Peripheral and central One of the most used scale in elderly population
Anticholinergic Drug Scale (ADS) Carnahan et al. 2002 [10] USA Older adults from rural long term care facilities (n = 98) List created using association with the SAA Significant correlation between SAA and anticholinergic drug scale Peripheral One of the most used scale in elderly population
- Focused on peripheral ADR
- ADS did not use the clinical input of expert clinicians and did not focus on the cognitive effects of anticholinergics
Clinician-rated Anticholinergic Score (CrAS) Han et al. 2001 [11] Canada Older inpatients (≥65 years) with diagnosed incident or prevalent delirium (n = 278) Expert-based list Exposure to anticholinergic medications is independently and specifically associated with a subsequent increase in delirium symptom severity Central Limited number of publications using this scale
Anticholinergic Impregnation Scale (AIS) Briet et al. 2017 [12] France Psychiatric patients (n = 7278) Expert-based list A high anticholinergic burden (AIS score >5) was associated with a higher rate of prescription of two anticholinergic adverse drug reaction correctors: laxatives and drugs against xerostomia Peripheral Limited number of publications using this scaleSpecific to psychiatric population and focused on peripheral ADR
Anticholinergic Burden Classification (ABC) Ancelin et al. 2006 [13] France Older adults participants (aged >60 years) through 63 randomly selected general practitioners in the Montpellier region of southern France (n = 372) Expert-based list Association between high anticholinergic burden and mild cognitive impairment Central Limited number of publications using this scale
Anticholinergic Activity Scale (AAS) Ehrt et al. 2010 [14] Norway A community-based cohort of patients with Parkinson's disease (n = 235) Expert-based list Association between anticholinergic drug use and cognitive decline in Parkinson's disease Central Limited number of publications using this scaleSpecific to patients with Parkinson's disease
Anticholinergic Effect on Cognition (AEC) Bishara et al. 2017 [15] UK Not applicable. List developed for older patients Expert-based list Not applicable Central Limited number of publications using this scale
Muscarinic Acetylcholine Receptor Antagonist Exposure (MARANTE) Klamer et al. 2017 [16] Belgium Not applicable. List developed for older patients Expert-based list Not applicable Central Limited number of publications using this scale
Anticholinergic Load scale (ACL) Sittironnarit et al. 2011 [17] Australia Older adults participants (aged >60 years): a cohort of 211 Alzheimer's disease patients, 133 mild cognitive impairment patients and 768 healthy controls Expert-based list Association between ACL and psychomotor speed and executive function in healthy older adults Central Limited number of publications using this scale
Anticholinergic Burden (ACB) Kiesel et al. 2018 [18] Germany Not applicableList developed for older patients Expert-based listBy different scores comparison and adapted to German prescription Not applicable Peripheral and central Limited number of publications using this scaleSpecific to Germany
Brazilian Anticholinergic Activity scale (BAA) Nery et al. 2019 [19] Brazil Not applicable. List developed for older patients Expert-based listBy different scores comparison and adapted to Brazilian prescription Not applicable Peripheral and central Limited number of publications using this scaleSpecific to Brazil
Anticholinergic Burden Scale (KABS) Jun et al. 2019 [20] South Korea Not applicable. List developed for older patients Expert-based listBy different scores comparison and adapted to South Korean prescription Not applicable Peripheral and central Limited number of publications using this scaleSpecific to South KoreaDrug dosages use in this evaluation
