Background: Expeditious processing of pathologic specimens, to make slides available in a timely manner for pathologist review, enables the pathologist to render diagnosis in a timely manner for patient care. This dramatically decreases the time it takes for clinicians to begin treatment of patients. This project describes the effects of moving to a 24 hour work cycle in our institute's Histology Laboratory. It compares similar time periods pre and post implementation to gauge effectiveness.
Design: Prior to implementation, the Histology Laboratory operated on a daylight shift and serviced two hospital campuses. Specimens were processed on two runs set up during the day and ran automatically during the night when no staff was on site. During the day, histology staff embedded blocks, made slides and performed stains on the specimens processed the night before. After months of planning, a 24 hour work cycle was implemented and a new workflow was designed. This included two additional work shifts - an evening and night shift. This change allowed continuous specimen processing, embedding, cutting and staining.
Results: The project measured the turnaround time by each bench from accession to sign-out prior to implementation and post implementation as illustrated in Table 1. TAT was significantly reduced in most benches.
