Abstract
BackgroundInappropriate antipsychotic prescribing is a key quality indicator by which clinical outcomes might be monitored and improved in long-term care (LTC), but limited evidence exists on the most effective strategies for reducing inappropriate antipsychotic use. ObjectivesThe objective of the study was to evaluate a multicomponent approach to reduce inappropriate prescribing of antipsychotics in LTC. DesignA prospective, stepped-wedge study design was used to evaluate the effect of the intervention. Settings and participantsInterdisciplinary staff at 10 Canadian LTC facilities. MethodsThe intervention consisted of an educational in-service, provision of evidence-based tools to assess and monitor neuropsychiatric symptoms (NPS) in dementia, and monthly interprofessional team meetings. The primary outcome was the proportion of residents receiving an antipsychotic without a diagnosis of psychosis using a standardized antipsychotic quality indicator. ResultsThe weighted mean change in inappropriate antipsychotic prescribing rate from baseline to 12-month follow-up was −4.6% [standard deviation (SD) = 2.8%, P < .0001], representing a 16.1% (SD = 17.0) relative reduction. After adjusting for site, the odds ratio for the inappropriate antipsychotic prescribing quality indicator at 12 months compared to baseline was 0.73 (95% confidence interval = 0.48-0.94; chi-square = 6.59; P = .01). There were no significant changes in related quality indicators, including falls, restraint use, or behavioral symptoms. Conclusions and implicationsThis multicomponent intervention was effective in reducing inappropriate antipsychotic prescribing in LTC without adversely affecting other domains related to quality of care, and offers a practical means by which to improve the care of older adults with dementia in LTC.
