Abstract

The data presented in this article is the provincial vitamin B12 test volume data for Alberta, Canada per month between April 1, 2015 and April 30, 2018. This data set was collected from the three different Alberta Public Laboratories Laboratory Information Systems: Cerner Millennium for Calgary, Sunquest for Edmonton, and MediTech for the remaining rural zones of Alberta (Bonnyville, Grand Prairie, Camrose, Red Deer, and Medicine Hat). An educational province-wide intervention aimed at reducing redundant testing was implemented on April 11, 2017 in Calgary, Alberta and Edmonton, Alberta and on May 2, 2017 in rural Alberta sites. All vitamin B12 test results in Alberta were appended with the educational comment “A normal test result indicates adequate stores and should not be repeated. However, if specific clinical situations require re-testing, the interval should not be sooner than 1 year.” Provincial monthly test volumes prior to this intervention ranged from 54,182 to 73,522 tests per month and after this intervention ranged from 59,116 to 74,006 tests per month. The total number of vitamin B12 tests ordered over the 37 months in Alberta was 2,444,724; 690,448 tests were ordered in Calgary, 1,029,315 tests were ordered in Edmonton, and 724,961 tests were ordered in rural sites. This data article was submitted as a companion paper to the related research article, “Implementation of an educational province-wide intervention to reduce redundant vitamin B12 testing: a cross-sectional study”[1].

Value of the Data
  • The table of monthly vitamin B12 test volume data ordered in Alberta over a 37-month span can serve as a reference for other Canadian jurisdictions when performing quality assessments in their clinical laboratories

  • Data can be used by clinical laboratories to determine appropriate vitamin B12 test ordering practices by Canadian physicians

  • This table can be used in collaboration by clinical laboratories to assess and compare the effectiveness of various interventions to reduce vitamin B12 redundant testing in Canada

  • This table can be used to assess and compare vitamin B12 test ordering practices by physicians in major cities in Alberta (Calgary and Edmonton) and rural Alberta sites

2. Experimental design, materials, and methods

Laboratory test volumes are publicly available data that are reported regularly to Alberta Health Services, the organizational body that oversees Alberta Public Laboratories. This data set was collected from the three different Alberta Public Laboratories Laboratory Information Systems: Cerner Millennium for Calgary, Sunquest for Edmonton, and MediTech for the remaining zones of Alberta (Bonnyville, Grand Prairie, Camrose, Red Deer, and Medicine Hat). The study consisted of all vitamin B12 tests ordered between April 1, 2015 and April 30, 2018 in Alberta. The monthly test volumes were recorded for each of these sites and total monthly provincial test volumes were also determined (Table 1). This table was then used to assess the effectiveness of an educational province-wide intervention aimed at reducing redundant vitamin B12 testing in Alberta [1].
