Assessing the feasibility of anticholinergic burden scales and measures in administrative data: A systematic review.

• This systematic review identified 28 anticholinergic burden scales and measures. • The Modified Anticholinergic Risk Scale is notably superior in terms of its scoring system. • The German Anticholinergic Burden Scale has excelled in scale development. • Adaptable and robust tools that work well with administrative data are needed. This systematic review aimed to identify and evaluate the quality and adaptability of existing anticholinergic burden scales and measures by using administrative dispensing data. A comprehensive literature search was conducted using the Medline, Embase, CINAHL, and Google Scholar databases from 2001 to 2022. Studies that introduced, updated, or modified anticholinergic burden scales and measures were included in this review. Quality assessment considered various aspects, including scoring systems, tool development criteria, and specific requirements tailored for administrative data. Twenty-eight anticholinergic burden scales and measures were identified in 14 countries. The Modified Anticholinergic Risk Scale excelled in the scoring system, while the German Anticholinergic Burden Scale stood out in the scale development process. However, significant variability was observed in methodologies, medication listings, and adaptability to administrative data. Quality assessment considers aspects such as potency, dose, exposure duration, longitudinal measurement, clinical interpretation, and compatibility with administrative data variables. The evaluation also considered tool development criteria including evidence for medication selection, panel expertise, relevance, updating methods, international applicability, validation, and clinical guidance. This review emphasizes the importance of adaptable and robust tools that can work well with administrative data to ensure patient safety and better health outcomes, given the ongoing evolution of anticholinergic medications. The findings of this systematic review provide valuable insights for clinicians and researchers in selecting the most appropriate anticholinergic burden scale or measure according to their specific needs and data sources. This systematic review was registered with PROSPERO (registration ID CRD42023423959). [ABSTRACT FROM AUTHOR]
