IntroductionProlonged Emergency Department (ED) stays, a global issue driving overcrowding, were exacerbated at our hospital by lab delays and extended waits, increasing patient stress. This study aimed to reduce hematology patients’ length of stay (LOS). Using the fishbone method to identify care barriers, three interventions were implemented: redesigned lab referral systems, an online specialist communication platform, and patient navigation floor maps.MethodsAt Tikur Anbessa Specialized Hospital (Ethiopia), a quality improvement initiative targeted hematology patients (n = 203 baseline; n = 63 post-intervention) with prolonged emergency department (ED) stays. Using two PDSA cycles, interventions included an online consultation platform, floor markings for navigation, and digitizing peripheral smear workflows via the I-Care system. Weekly data on consultation time, lab turnaround time (TAT), navigation errors, and length of stay (LOS) were analyzed with run charts and Interrupted Time Series (ITS) regression.ResultsMedian LOS decreased by 62.5% (144–54 hours; p ConclusionsTargeted interventions improved care and efficiency at Tikur Anbessa Hospital, but sustained reductions in ED LOS were limited by data gaps and discontinued initiatives. Future efforts in resource-limited settings should prioritize continuous monitoring, stakeholder collaboration, and staff well-being.
