ABSTRACT Appropriate medication prescribing for nursing home residents remains a challenge.
The purpose of this study was to conduct a narrative review of the published literature describing randomized controlled trials that used interventions to improve suboptimal prescribing in nursing homes.
The PubMed, International Pharmaceutical Abstracts, and EMBASE databases were searched for articles published in the English language between January 1975 and December 2009, using the terms drug utilization, pharmaceutical services, aged, long-term care, nursing homes, prescribing, geriatrics, and randomized controlled trial. A manual search of the reference lists of identified articles and the authors' files, book chapters, and recent review articles was also conducted. Abstracts and posters from meetings were not included in the search. Studies were included if they: (1) had a randomized controlled design; (2) had a process measure outcome for quality of prescribing or a distal outcome measure for medication-related adverse patient events; and (3) involved nursing home residents.
Eighteen studies met the inclusion criteria for this review. Seven of those studies described educational approaches using various interventions (eg, outreach visits) and measured suboptimal prescribing in different manners (eg, adherence to guidelines). Two studies described computerized decision-support systems to measure the intervention's impact on adverse drug events (ADEs) and appropriate drug orders. Five studies described clinical pharmacist activities, most commonly involving a medication review, and used various measures of suboptimal prescribing, including a measure of medication appropriateness and the total number of medications prescribed. Two studies each described multidisciplinary and multifaceted approaches that included heterogeneous interventions and measures of prescribing. Most (15/18; 83.3%) of these studies reported statistically significant improvements in >or=1 aspect of suboptimal prescribing. Only 3 of the studies reported significant improvements in distal health outcomes, and only 3 measured ADEs or adverse drug reactions. CONCLUSIONs: Mixed results were reported for a variety of approaches used to improve suboptimal prescribing. However, the heterogeneity of the study interventions and the various measures of suboptimal prescribing used in these studies does not allow for an authoritative conclusion based on the currently available literature.

    ABSTRACT: Background Drug related problems (DRPs) are frequent and cause suffering for patients and substantial costs for society. Multi-dose drug dispensing (MDDD) is a service by which patients receive their medication packed in bags with one unit for each dose occasion. The clinical decision support system (CDSS) electronic expert support (EES) analyses patients' prescriptions in the Swedish national e-prescription repository and provides alerts if potential DRPs are detected, i.e. drug-drug interactions, duplicate therapy, drug-disease contraindications, high dose, gender warnings, geriatric, and paediatric alerts. Objective To analyse potential DRPs in patients with MDDD, detected by means of EES. Setting A register study of all electronically stored prescriptions for patients with MDDD in Sweden (n = 180,059) March 5-June 5, 2013. Method Drug use and potential DRPs detected in the study population during the 3 month study period by EES were analysed. The potential DRPs were analysed in relation to patients' age, gender, number of drugs, and type of medication. Main outcome measure Prevalence of potential DRPs measured as EES alerts. Results The study population was on average 75.8 years of age (±17.5, range 1-110) and had 10.0 different medications (±4.7, range 1-53). EES alerted for potential DRPs in 76 % of the population with a mean of 2.2 alerts per patient (±2.4, range 0-27). The older patients received a lower number of alerts compared to younger patients despite having a higher number of drugs. The most frequent alert categories were drug-drug interactions (37 % of all alerts), duplicate therapy (30 %), and geriatric warnings for high dose or inappropriate drugs (23 %). Psycholeptics, psychoanaleptics, antithrombotic agents, anti-epileptics, renin-angiotensin system agents, and analgesics represented 71 % of all drugs involved in alerts. Conclusions EES detected potential DRPs in the majority of patients with MDDD. The number of potential DRPs was associated with the number of drugs, age, gender, and type of medication. A CDSS such as EES might be a useful tool for physicians and pharmacists to assist in the important task of monitoring patients with MDDD for potential DRPs.

    ABSTRACT: Background Antipsychotic medications are commonly used to manage the behavioral and psychological symptoms of dementia. Several large studies have demonstrated an association between treatment with antipsychotics and increased morbidity and mortality in people with dementia. Aims To assess the effectiveness of interventions used to reduce inappropriate prescribing of antipsychotics to the elderly with dementia in residential care. Method Systematic searches were conducted in 12 electronic databases. Reference lists of all included studies and forward citation searching using Web of Science were also conducted. All quantitative studies with a comparative research design and studies in which recognized methods of qualitative data collection were used were included. Articles were screened for inclusion independently by 2 reviewers. Data extraction and quality appraisal were performed by 1 reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Results Twenty-two quantitative studies (reported in 23 articles) were included evaluating the effectiveness of educational programs (n = 11), in-reach services (n = 2), medication review (n = 4), and multicomponent interventions (n = 5). No qualitative studies meeting our inclusion criteria were identified. Eleven studies were randomized or controlled in design; the remainder were uncontrolled before and after studies. Beneficial effects were seen in 9 of the 11 studies with the most robust study design with reductions in antipsychotic prescribing levels of between 12% and 20%. Little empirical information was provided on the sustainability of interventions. Conclusion Interventions to reduce inappropriate prescribing of antipsychotic medications to people with dementia resident in care homes may be effective in the short term, but longer more robust studies are needed. For prescribing levels to be reduced in the long term, the culture and nature of care settings and the availability and feasibility of nondrug alternatives needs to be addressed.

    ABSTRACT: The use of benzodiazepines has been advised against in older people, but prevalence rates remain high. To review the evidence for interventions aimed at reducing benzodiazepine use in older people. We conducted a systematic review, assessment of risk of bias and meta-analyses of randomised controlled trials of benzodiazepine withdrawal and prescribing interventions. Ten withdrawal and eight prescribing studies met the inclusion criteria. At post-intervention, significantly higher odds of not using benzodiazepines were found with supervised withdrawal with psychotherapy (odds ratio (OR) = 5.06, 95% CI 2.68-9.57, P<0.00001) and withdrawal with prescribing interventions (OR = 1.43, 95% CI 1.02-2.02, P = 0.04) in comparison with the control interventions treatment as usual (TAU), education placebo, withdrawal with or without drug placebo, or psychotherapy alone. Significantly higher odds of not using benzodiazepines were also found for multifaceted prescribing interventions (OR = 1.37, 95% CI 1.10-1.72, P = 0.006) in comparison with control interventions (TAU and prescribing placebo). Supervised benzodiazepine withdrawal augmented with psychotherapy should be considered in older people, although pragmatic reasons may necessitate consideration of other strategies such as medication review.
