General practitioners' assessment of interventions applied to optimize laboratory test utilization: a cross-sectional survey study.

General practitioners (GPs) in the Region of Southern Denmark 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.

A randomized controlled study of biochemical tests in primary care: interventions can reduce the number of tests but usage does not become more appropriate.

Objectives: The use of laboratory tests increases worldwide, and to some extent their use is likely to be inappropriate. Although primary care is responsible for a substantial proportion of requests, this sector is less extensively investigated than hospitals.

Methods: We tested the effect of six combinations of four interventions applied to 313 primary care clinics, using vitamin D as model test (253,762 vitamin D results).

The impact of interventions applied in primary care to optimize the use of laboratory tests: a systematic review.

Laboratory tests are important tools in primary care, but their use is sometimes inappropriate. The aim of this review is to give an overview of interventions applied in primary care to optimize the use of laboratory tests. A search for studies was made in the MEDLINE and EMBASE databases.
