Introduction
This campaign provides information on Potentially Unnecessary Biochemical Testing one year after a series of interventions were conducted to reduce the number of tests performed without clinical indication.
- In August 2016, Eastern Health provided a new requisition form which omitted blood urea, LDH, and AST.
- In 2017, Quality of Care NL visited family doctors and discussed the need for ordering blood urea, LDH, creatine kinase, and ferritin.
- Monthly use of these five tests + Uric Acid from Jan 2015 – Dec 2017 by family doctors at Eastern Health is presented.
The Problem
The ordering of blood urea, LDH, creatine kinase, AST, uric acid, and ferritin may sometimes be unnecessary.
Our Data
Urea
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $267,220

LDH
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $37,136
Creatine Kinase
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $44,264
AST
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $31,028
Ferritin
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $159,280
Uric Acid
Reduction in the use of uric acid, which was not removed from the requisition form and was not academically detailed, suggests a reduction in overall testing due to physician awareness of appropriate testing.
The annual cost avoidance in Eastern Health resulting from the reduction in test usage is: $24,716
Total Annual Cost Avoidance in Eastern Health from Unnecessary Biochemical Testing
Deletion of tests from the requisition form, as well as academic detailing appear to be associated with reduction in unnecessary use of biochemical tests.
