INTRODUCTION: Inappropriate request for laboratory tests is a challenging problem and an important cause for additional healthcare costs. Indeed, it may have further ambiguity for the clinicians. This study aimed to design an education‐based program to reduce unnecessary laboratory testing orders and the associated costs. MATERIALS AND METHODS: In this interventional prospective study that took place in an educational hospital, the type and frequency of selected laboratory testing requested by gynecology, and obstetrics residents in the patients with gestational diabetes mellitus, preeclampsia, preterm labor, and premature preterm rupture of the membrane as well as cesarean section and normal vaginal delivery were analyzed periodically in a 1‐year interval. At the same time, continuous educational supports and monitoring were performed. The results were compared before and after interventions. RESULTS: The educational intervention regardless of the etiologies of the admission, decreased the requested laboratory testing significantly (p < 0.001), except for CBC. Indeed, no near misses or delays in treatment were observed. Cost analysis showed a 31.3% reduction of expenses per inpatient day due to the decrease in the number of daily laboratory testing ordered. CONCLUSIONS: Appropriate education and continuous monitoring of the residents could reduce the unrequired laboratory testing as well as healthcare costs.
