Paid Time Off Pressure in Emergency Medicine: Vacation Conflict Risk in the Context of Group Size, and Shift Coverage.
Article in The Journal of emergency medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEmergency departments (EDs) are confronting steadily rising patient visit volumes, ongoing workforce shortages, and the continuous requirement for uninterrupted 24/7/365 coverage. These pressures create substantial tension between maintaining operational efficiency and supporting physician work-life balance, with paid time off (PTO) emerging as a particularly challenging area of conflict.
objectivesThe aim of this study was to introduce and define "PTO pressure" (PTOP), a novel probabilistic metric that quantifies the minimum likelihood that an emergency physician's requested vacation week will conflict with the department's maximum allowable number of concurrent absences.
methodsUsing combinatorial probability modeling, we evaluated PTOP across varying department sizes. The model assumes uniform random selection of vacation weeks and systematically examines how group size (P physicians), annual PTO entitlement (k weeks), and the maximum number of allowable concurrent absences interact to influence scheduling conflict risk.
resultsPTOP rises significantly with smaller group sizes, higher PTO entitlements, and stricter limits on concurrent absences. For example, in a 12-physician group with 6 weeks of annual PTO and only 4 allowable concurrent absences, the minimum PTOP was approximately 0.357. While larger groups naturally reduce PTOP, they still require deliberate calibration of shift equity, backup staffing resources, and productivity expectations to ensure safe coverage and maintain fairness among physicians.
conclusionUnresolved PTO scheduling conflicts contribute meaningfully to physician dissatisfaction, moral distress, and burnout risk in a specialty already reporting among the highest burnout rates. Emergency medicine leaders should incorporate PTOP modeling into workforce planning strategies. Doing so will better align staffing expansion with equitable and sustainable vacation policies, ultimately supporting physician well-being, retention, and long-term workforce resilience.
