Primary Care Physicians' Challenges in Ordering Clinical Laboratory Tests and Interpreting Results

Abstract

Primary care physicians routinely experience uncertainty and challenges in ordering and interpreting diagnostic laboratory tests. With more than 500 million primary care patient visits per year, the level of uncertainty reported in this study potentially affects 23 million patients per year and raises significant concerns about the safe and efficient use of laboratory testing resources. Improvement in information technology and clinical decision support systems and quick access to laboratory consultations may reduce physicians' uncertainty and mitigate these challenges.
