Description
Adi Shuchami and six colleagues ask how often children's emergency departments repeat blood tests that community clinics just ran. Repeats within hours rarely change care, yet they cost money, time, and sore arms. Their dataset covered a nationwide health plan's records for children aged three months to eighteen years. Repeat rates for blood counts, electrolytes, and an inflammation marker were judged against preset need criteria, then a learning model tried to predict which repeats were truly needed.
Only about thirteen to nineteen percent of repeats proved justified, depending on the test. A standard boosted tree model predicted need with up to ninety two percent accuracy, and stayed useful when tuned to miss no needed repeat for two of the three tests. Shuchami and the team say live practice studies come next.
