Laboratory Test Ordering Patterns in Pediatrics From Naturopaths and General Practitioners

Abstract

Abstract Objectives Naturopathic medicine emphasizes prevention and the self-healing process through natural therapies. Naturopathic doctors (NDs) use clinical laboratories as frequently as traditionally trained physicians. Here we evaluated the test-ordering patterns of NDs and general practitioners (GPs). Methods A retrospective analysis was performed from a tertiary pediatric hospital. We analyzed tests ordered by NDs who used laboratory services and compared the test ordering patterns with GPs from adolescent medicine, family medicine, or pediatric clinics. Requests were categorized into 10 groups. We determined the tests with the highest ordering frequencies, as well as the percentage of tests that had an abnormal result. Results NDs ordered more tests per patient per date of specimen collection compared with GPs. The most frequently ordered tests by NDs were trace elements and toxic metals (23.2% of total), allergens (21.8%), and general chemistry (15.3%). For the same test, the percentage of tests with an abnormal result was significantly lower for NDs than GPs. Conclusions We observed different ordering patterns between NDs and GPs. NDs ordered more esoteric tests and had lower rates of abnormal test results compared with GPs. Understanding the patterns of testing from different providers’ specialties is useful to choose effective laboratory stewardship interventions.
