Inappropriate laboratory testing requests: perspectives of clinical laboratory professionals

Introduction: Laboratory examinations constitute a major factor in achieving the correct clinical diagnosis for patients. However, the ordering of unnecessary or inappropriate laboratory testing remains common, with consequent consumption of laboratory resources whether human or material. The present work evaluated the level of satisfaction of laboratory practitioners toward the appropriateness of laboratory tests ordered by physicians. Methods: This cross-sectional study involved a total of 256 medical laboratory practitioners representing different qualifications and health care sectors, who answered several questions concerning their knowledge and attitudes toward inappropriate laboratory testing ordered by physicians. Results: More than 85% of respondents agreed with the definition provided in the survey, which is substantially consistent with prior studies. More than 90% affirmed the associated drain on time and resources. However, discrepant responses were received concerning physician awareness of test availability, and participants reported laboratory staff arguments with physicians due to orders for unnecessary tests. Data showed that unnecessary orders were mainly requested by physicians of less experience. Conclusions: Ultimately, dissatisfaction was manifest among clinical laboratory professionals, and educational interventions are required to moderate request behaviors.
