To gain insight into the volume of vitamin B12- and D-determinations over time.
A retrospective cohort study.
Using declaration data of around 3.5 million insured Dutch citizens we examined the volume of vitamin B12- and D-testing between 2015-2019. Both trends in number and proportion of patients receiving a vitamin B12- and D determination were assessed.
Between 2015-2019 the number of vitamin B12-determinations increased by 98,1% and the number of vitamin D-determinations by 112%. The proportion of patients receiving a determination increased from 4,8% to 8,4% for vitamin B12 and from 4,7% to 9,1% for vitamin D over the examined period.
Both the number of and proportion of patients receiving a vitamin B12- and D-determinations increased over the examined time period. Our findings emphasize the need for proper patient and physician information regarding the indications which justify vitamin B12- or D testing, in order to reduce and prevent overtesting.
深入了解维生素B12和维生素D检测量随时间的变化情况。
一项回顾性队列研究。
利用约350万荷兰参保公民的申报数据，我们研究了2015年至2019年间维生素B12和维生素D检测量。评估了接受维生素B12和维生素D检测的患者数量及比例的趋势。
在2015年至2019年间，维生素B12检测量增加了98.1%，维生素D检测量增加了112%。在研究期间，接受维生素B12检测的患者比例从4.8%增至8.4%，接受维生素D检测的患者比例从4.7%增至9.1%。
在研究时间段内，接受维生素B12和维生素D检测的患者数量及比例均有所增加。我们的研究结果强调，需要向患者和医生提供关于维生素B12或维生素D检测合理指征的适当信息，以减少和防止过度检测。
