General Practitioners’ Assessment Of Interventions Applied To Optimize Laboratory Test Utilization

Abstract

General practitioners (GPs) in the Makkah hospitals were randomly allocated to a range of interventions to optimize their use of Vitamin D tests over one year. The aim of the current survey study was to investigate GPs assessment of the interventions. Using REDCap web-platform, we invited 638 GPs to participate in a survey about their experiences of guidelines, feedback reports, non-interruptive alerts, and interruptive alerts. The questions were customized for the different interventions. We received responses from only 131 GPs (21%), but no differences in gender, age, or type of GP clinic were observed between responders and invited GPs. Approximately half of the GPs found that guidelines were helpful, and a similar proportion of GPs read the feedback reports ‘often’ or ‘always′. The pop-up alerts were accepted when used for maximum three months for often-used tests. In contrast, alerts were accepted for long periods for rarely-used tests. The groups that were exposed to the interruptive alert found it ‘problematic’ that it appeared every time vitamin D was requested. Guidelines and feedback reports on tests numbers were accepted, but it was previously found, that they had little effect on improving the use of biochemical tests. Pop-up alerts in the requesting IT system can produce alert fatigue. Future research should focus on developing feedback reports th[1]at – when possible - also include relevant clinical information, and pop-up alerts should for often used tests be displayed only for weeks or a few months, but can be repeated.
