COVID-19 and clinic workflow optimization using lean six sigma.

OBJECTIVES
The COVID-19 pandemic has fundamentally changed the workflow of clinics. We applied Lean Six Sigma processes to optimize clinic workflow to reduce patient wait times and improve the patient experience.


STUDY DESIGN
Prospective cohort study.


METHODS
We implemented (1) pushing most extended wait times to the end of the workflow by rooming the patient directly and (2) using distractions during the waiting process by using educational videos and a timer for physician arrival in the patient exam room. We compared the patient wait times and subcomponents of Press Ganey scores as a surrogate for changes in patient experience and satisfaction from the preimplementation period (n = 277) to the 3-month (September 1, 2020, to November 30, 2020) postimplementation period (n = 218).


RESULTS
There was a significant reduction in overall throughput time (38 vs 35 minutes) and wait before rooming (11 vs 8 minutes), and increased physician time with patients (15 vs 17 minutes) (P < .0001 for all). These results corresponded with a significant improvement in Press Ganey subcomponents of (1) waiting time in the exam room before being seen by the care provider, (2) degree to which you were informed about any delays, (3) wait time at clinic (from arriving to leaving), and (4) length of wait before going to an exam room (P < .001 for all).


CONCLUSIONS
Simple, inexpensive measures can improve patient engagement and provide a safe setting for patients for clinic visits in the wake of COVID-19. In the future, clinics' common wait areas could be reappropriated to increase the number of clinic exam rooms.
