Improving drug prescription in general practice using a novel quality improvement model

Abstract

Introduction

Quality improvement (QI) clusters have been established in many countries to improve healthcare using the Breakthrough Series’ collaboration model. We investigated the effect of a novel QI approach based on this model of performed medication reviews and drug prescription in a Norwegian municipality.

Methods

All 27 General Practitioners (GPs) in a mid-size Norwegian municipality were invited to join the intervention, consisting of three peer group meetings during a period of 7–8 months. Participants learned practical QI skills by planning and following up QI projects within drug prescription practice. Evaluation forms were used to assess participants’ self-rated improvement, reported medication review reimbursement codes (MRRCs) were used as a process measure, and defined daily doses (DDDs) of potentially inappropriate drugs (PIDs) dispensed to patients aged 65 years or older were used as outcome measures.

Results

Of the invited GPs, 25 completed the intervention. Of these, 76% self-reported improved QI skills and 67% reported improved drug prescription practices. Statistical process control revealed a non-random increase in the number of MRRCs lasting at least 7 months after intervention end. Compared with national average data, we found a significant reduction in dispensed DDDs in the intervention municipality for benzodiazepine derivates, benzodiazepine-related drugs, drugs for urinary frequency and incontinence and non-steroid anti-inflammatory and antirheumatic medications.

Conclusion

Intervention increased the frequency of medication reviews, resulting in fewer potentially inappropriate prescriptions. Moreover, there was self-reported improvement in QI skills in general, which may affect other practice areas as well. Intervention required relatively little absence from clinical practice compared with more traditional QI interventions and could, therefore, be easier to implement.

KEY POINT

• The current study investigated to what extent a novel model based on the Breakthrough Series’ collaborative model affects GP improvement skills in general practice and changes their drug prescription.

KEY FINDINGS

• Most participants reported better improvement skills and improved prescription practice.

• The number of dispensed potentially inappropriate drugs decreased significantly in the intervention municipality compared with the national average.

• The model seemed to lead to sustained changes after the end of the intervention.
