Abstract:

Purpose: To determine if patient-specific prescriber feedback for general medical practitioners (GPs), supported by educational material mailed to their patients, would increase home medicines review (HMR) rates.

Methods: An observational study was conducted using the Repatriation Pharmaceutical Benefits Scheme (RPBS) Pharmacy Claims Database. The intervention group (n = 40 270) included all veterans aged ≥65 years, dispensed ≥5 unique medicines each month over a 4 month period. Comparison group veterans (n = 49,227) were those who did not have ≥5 or more unique medicines dispensed each month, but did have at least one prescription each month and ≥20 prescriptions over 4 months, of which five were unique medicines, Intervention GPs (n = 11,384) were subdivided into 2 groups: GPs with intervention veterans (n = 2097) and GPs with both intervention and comparison group veterans (n = 9287). The comparison group of GPs (n = 3630) were primary prescribers to the comparison veterans only. Rates of HMRs pre and post-intervention and the number of new GPs participating in HMR services were examined.

Results: There was a significant increase in HMR rates in intervention group, from 2.2 per 1000 in the pre-period to 4.6 per 1000 per month in the post-intervention period (Rate Ratio (RR) 2.06, 95% Confidence Interval (CI) (1.90, 2.22), p < 0.0001). HMR rates increased in the intervention group compared with the comparison group (p < 0.0001). HMR rates increased in the intervention group GPs compared with the comparison group (RR 1.79, 95% CI (1.58, 2.02), p < 0.0001).

Conclusion: Patient-specific feedback provided to GPs, supported by educational material mailed directly to their patients increased HMR rates for targeted veterans and increased GP participation in the delivery of HMRs. Copyright © Commonwealth of Australia 2007. Published by John Wiley & Sons Ltd.
