Road to Better Work-Life Balance? Lean Redesigns and Daily Work Time among Primary Care Physicians

PURPOSE: To assess the impact of Lean primary care redesigns on the amount of time that physicians spent working each day. METHODS: This observational study was based on 92 million time-stamped Epic® EHR access logs captured among 317 primary care physicians in a large ambulatory care delivery system. Seventeen clinic facilities housing 46 primary care departments were included for study. We conducted interrupted time series analysis to monitor changes in physician work patterns over 6 years. Key measures included total daily work time; time spent on “desktop medicine” outside the exam room; time spent with patients during office visits; time still working after clinic, i.e., after seeing the last patient each day; and remote work time. RESULTS: The amount of time that physicians spent on desktop EHR activities throughout the day, including after clinic hours, decreased by 10.9% (95% CI: −22.2, −2.03) and 8.3% (95% CI: −13.8, −2.12), respectively, during the first year of Lean implementation. Total daily work hours among physicians, which included both desktop activity and time in office visits, decreased by 20% (95% CI: −29.2, −9.60) by the third year of Lean implementation. CONCLUSIONS: These findings suggest that Lean redesign may be associated with time savings for primary care physicians. However, since this was an observational analysis, further study is warranted (e.g., randomized trial) —to determine the impact of Lean interventions on physician work experiences.
