A cluster randomized trial assessing the impact of personalized prescribing feedback on antibiotic prescribing for uncomplicated acute cystitis to family physicians.

OBJECTIVE: To evaluate the impact of personalized prescribing portraits on antibiotic prescribing for treating uncomplicated acute cystitis (UAC) by Family Physicians (FPs). DESIGN: Cluster randomized control trial. SETTING: The intervention was conducted in the primary care setting in the province of BC between December 2010 and February 2012. PARTICIPANTS: We randomized 4 833 FPs by geographic location into an Early intervention arm (n = 2 417) and a Delayed control arm (n = 2 416). INTERVENTION: The Education for Quality Improvement in Patient Care (EQIP) program mailed to each FP in BC, a 'portrait' of their individual prescribing of antibiotics to women with UAC, plus therapeutic recommendations and a chart of trends in antibiotic resistance. MAIN OUTCOME MEASURES: Antibiotic prescribing preference to treat UAC. RESULTS: Implementing exclusion criteria before and after a data system change in the Ministry of Health caused the arms to be unequal in size-intervention arm (1 026 FPs, 17 637 UAC cases); control arm (1 352 FPs, 25 566 UAC cases)-but they were well balanced by age, sex and prior rates of prescribing antibiotics for UAC. In the early intervention group probability of prescribing nitrofurantoin increased from 28% in 2010 to 38% in 2011, a difference of 9.9% (95% confidence interval [CI], 9.1% to 10.7. Ciprofloxacin decreased by 6.2% (95% CI: 5.6% to 6.9%) and TMP-SMX by 3.7% (95% CI: 3.1% to 4.2%). Among 295 FPs who completed reflective surveys, 52% said they were surprized by the E. coli resistance statistics and 57% said they planned to change their treatment of UAC. CONCLUSION: The EQIP intervention demonstrated that feedback of personal data to FPs on their prescribing, plus population data on antibiotic resistance, with a simple therapeutic recommendation, can significantly improve prescribing of antibiotics.

Sociotechnical design of an electronic tool for managing transient ischemic attack in the emergency department.

This paper describes the adoption of a prototype electronic decision support tool for managing transient ischemic attack (TIA) in the Emergency Department (ED) of a health region in Canada. A clinician-driven sociotechnical design approach is used to develop, test and implement the prototype with the aim to improve TIA management in the ED. In this study, we worked closely with ED staff to: identify issues and needs in TIA management; build/test/refine prototype versions of the electronic TIA decision support tool; and explore strategies to implement the tool for routine use in the ED. A blood protein biomarker test under development will also be incorporated as part of this tool in a subsequent phase. Thus far the prototype has demonstrated the potential to improve triage, risk stratification, and disposition decisions based on historical TIA and mimic cases. A prospective multi-site clinical utility study is planned for spring of 2016.
