STUDY OBJECTIVE: We assess the effect of sequential modifications in laboratory processing, including pneumatic tube transport and fully computerized order management, on laboratory turnaround time in the emergency department (ED). METHODS: This was an observational analysis of a comprehensive computerized database derived from ED, laboratory, and hospital information systems. The setting was an academic urban ED with annual census of 38,000. Participants and interventions included all patients who had laboratory testing (serum sodium level, troponin level, or CBC count) during three 1-month study periods: before pneumatic tube and computerized order management (prepneumatic tube), after pneumatic tube but before computerized order management (postpneumatic tube), and after both pneumatic tube and computerized order management (postpneumatic tube/computerized order management). The primary outcome measure was median laboratory turnaround time, reported with interquartile ranges. Additional measures included ED census and number of laboratory tests ordered during each study period. RESULTS: The monthly ED census was 3,021, 3,428, and 3,066 for the prepneumatic tube, postpneumatic tube, and postpneumatic tube/computerized order management periods. There was a significant decrease in turnaround time with each period and each test over time. For serum sodium testing, the median laboratory turnaround time decreased from 55.9 to 46.7 to 37.2 minutes for prepneumatic tube, postpneumatic tube, and postpneumatic tube/computerized order management periods. For CBC-count testing, median times decreased from 55.6 to 42.2 to 36.3 minutes, respectively. For troponin I testing, median times decreased from 52.8 to 41.8 to 30.6 minutes, respectively. CONCLUSION: Changes in laboratory specimen management, including the use of a pneumatic tube and computerized order management, resulted in a progressive decrease in laboratory turnaround time in the study ED.
