Laboratory sample turnaround times: do they cause delays in the ED?

摘要: Objectives  Blood tests are requested for approximately 50% of patients attending the emergency department (ED). The time taken to obtain results is perceived as a common reason delay. objective this study was therefore investigate turnaround (TAT) blood and whether affects patient length stay (LOS) identify potential areas improvement. Methods  A time-in-motion performed at ED John Radcliffe Hospital (JRH), Oxford, UK. duration each stages leading up receipt 101 biochemistry haematology recorded, along with corresponding patient's LOS. Results  findings reveal that mean become available 1 hour 6 minutes (95% CI: 29 2 hours 13 minutes), while samples took 42 minute 4 21 some positive correlation noted LOS, but no significant variation between different days or shifts. Conclusions  With fastest 10% being reported within 35 (haematology) 5 (biochemistry) request, our showed delays can be attributable laboratory TAT. Given limited ability further improve processes, solutions improving TAT need come from collaborative integrated approach includes strategies before reach downstream review results.
