- W2982023377 abstract "We describe the implementation of an Alberta-wide intervention aimed at educating clinicians about redundant vitamin B12 testing. We hypothesized that the introduction of an educational comment outlining recommended vitamin B12 test intervals would reduce the annual number of vitamin B12 tests performed. We performed a cross-sectional observational study that included all vitamin B12 tests ordered in Alberta between May 1, 2017 and April 30, 2018. An educational comment was appended to all vitamin B12 test results in Alberta beginning May 2, 2017. Using a simple seasonal model, we compared predicted versus observed vitamin B12 test volumes for the 12-month period following the introduction of the educational comment. The sole outcome measured was the monthly change in volume of vitamin B12 testing. A cost-analysis of the effects of the intervention on test volumes was also performed. Over the sum of the first 12 months of the intervention, 18,000 more vitamin B12 tests were ordered compared to the predicted value in Alberta. With an estimated cost of $7 per test, this resulted in a $126,000 increase in costs for vitamin B12 testing provincially. An educational intervention aimed at limiting inappropriate vitamin B12 testing in Alberta did not alter testing as desired. Multiple utilization management strategies and a longer observation period may be needed to reduce redundant vitamin B12 testing." @default.
