Background: Pharmacotherapy in older adults is one of the most challenging aspects of patient care. Older people are prone to drug-related problems such as adverse effects, ineffectiveness, underdosage, overdosage, and drug interactions. Anticholinergic medications are associated with poor outcomes in older patients, and there is no specific intervention strategy for reducing drug burden from anticholinergic activity medications. Little is known about the effectiveness of current interventions that may likely improve the anticholinergic prescribing practice in older adults. Aims: This review seeks to document all types of interventions aiming to reduce anticholinergic prescribing among older adults and assess the current evidence and quality of existing single and combined interventions. Methods: We systematically searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, and PsycINFO from January 1990 to August 2021. Only studies that examined the effect of interventions in older people focused on improving compliance with anticholinergic prescribing guidelines with quantifiable data were included. The primary outcome of interest was to find the effectiveness of interventions that enhance the anticholinergic prescribing practice in older adults. Results: We screened 3168 records and ended up in 23 studies that met the inclusion criteria. We found only single-component interventions to reduce anticholinergic prescribing errors in older people. Pharmacists implemented interventions without collaboration in nearly half of the studies (n = 11). Medication review (43%) and education provision (26%) to healthcare practitioners were the most common interventions. Sixteen studies (70%) reported significant reductions in anticholinergic prescribing errors, whereas seven studies (30%) showed no significant effect. Conclusion: This systematic review suggests that healthcare practitioner-oriented interventions have the potential to reduce the occurrence of anticholinergic prescribing errors in older people. Interventions were primarily effective in reducing the burden of anticholinergic medications and assisting with deprescribing anticholinergic medications in older adults.

In Saudi Arabia, the older adult population is growing and is projected to increase three-fold by 2030. Potentially inappropriate medications (PIMs) are harmful to older adults’ and have a direct impact on clinical, health and economic outcomes. Pharmacists have a vital role in medication tailoring for older adults as multidisciplinary team members. However, there is also a paucity of research regarding pharmacists’ participation in detecting and avoiding PIMs use among older adults in Saudi Arabia. A cross-sectional, self-administered survey was conducted to assess the knowledge, practices, and attitude of pharmacists from seven hospitals and ten community pharmacies in Jeddah, Saudi Arabia. The survey comprised three sections; (i) identifying participants’ general characteristics, (ii) assessing their knowledge of PIMs use in older adults and (iii) examining the pharmacist’s attitude towards the procedures followed in dispensing for older adults. Inferential and descriptive statistics were used to analyse the survey data. A total of 157 community and hospital pharmacists participated in this study. Most of them dispensed medication weekly to older adults (85.4%), and 43.3% had relevant work experience of six to ten years. Though 44.6% of the participants were aware of PIMs that older adults should avoid, only 10.8% claimed adequate knowledge about PIMs. From the given three clinical case scenarios, a minority of pharmacists (21.7%) chose the correct answers, with a mean score of 2.38 ± 2.91 (95% CI 2.35–3.15). Participants who claimed to have knowledge of PIMs had a significantly higher mean score than those who did not, 4.59 ± 2.81 25 (95% CI 2.35–2.61). A minority of the pharmacists (14.7%) used screening tools such as STOPP, Beers criteria, or Medication Appropriateness Index (MAI) to detect PIMs in older adults. No statistically significant differences were detected when comparing the levels of knowledge of pharmacists with 1 to 5 years of practice to pharmacists with 6 to 15 and more years of experience (p = 0.431). Pharmacists’ knowledge, attitude and practices toward PIMs use in older adults in Saudi Arabia should be improved. The application of PIMs detection tools such as STOPP/START or Beers criteria currently has no place in day-to-day pharmacists’ roles in Saudi Arabia. Therefore, concerned stakeholders should develop educational programs to improve pharmacists’ knowledge of PIMs and promote the effective use of PIM screening tools such as Beers and STOPP criteria in their practice.
