Background
Residency programs have adopted blocked scheduling to improve the learning climate yet more intensive rotations still impact resident wellness. The effect of changing the alignment of inpatient resident teams on patient care opportunities is not well known. We sought to evaluate the association of new daily schedule (dubbed ‘Mariokart’) compared to a traditional schedule on patient care opportunities, days off, and duty-hour violations.
Methods
A non-randomized pre - and post-intervention study examining the daily patient census for residents covering a general internal medicine inpatient service within an internal medicine residency program at a single academic medical center from July 2018 to June 2021. The main outcome was the median daily patient census per resident inpatient team before and after the implementation of the ‘Mariokart’ schedule. Secondary outcomes included days off in a 28-day cycle, patient-care opportunities, and resident-reported duty-hour violations. A two-sided t-test was used to determine differences between the groups.
Results
In comparing 20 months prior to implementation of the ‘Mariokart’ schedule to 15 months post-implementation, the median census of the resident service was 60 patients (IQR 53.0–67.0) for the traditional model and 54 (IQR 49.0–59.0) for the MarioKart model. The median census per team was 12 (IQR 10.0–15.0) for the traditional model and 13.5 (IQR 12.25–14.75) for the MarioKart model. Total patient days per team were 288 (IQR 254.4-321.6) for the traditional model and 303.8 (275.6-331.9) for the MarioKart model (p < 0.001). Under the MarioKart model, residents had an extra 1.5 days off per 28 days compared to the traditional model. Short break violations for the entire program and for the general inpatient service were significantly reduced.
Conclusions
In this nonrandomized study of an alternate day-to-day schedule that reduced days worked for residents in a general medicine inpatient service, there was no decline in patient-care opportunities. This alternate organization of residents suggests that residency programs can innovate at a systems level to adjust resident schedules to provide more time off without a detriment to patient care opportunities.
