Worker inexperience and a flawed clinical laboratory information system caused mishaps that cost Ohio State University's Wexner Medical Center nearly $1 million. Those details were gleaned from a government-mandated analysis of Ohio State's mishandling of six proficiency-test samples that was conducted by Vanderbilt University and obtained by The Dispatch. The lab, at Rhodes Hall, is the core of a university network of more than 70 labs. The lab network plays a key role in patient care ? 97 percent of inpatient cases and 24 percent of outpatient cases involve ordering lab services.
