X+Y residency scheduling built by mathematicians

X+Y scheduling requires simultaneous optimization of two distinct schedule types — inpatient rotation blocks and ambulatory continuity clinic weeks — that must interlock without conflicts. Traditional scheduling tools handle these separately, creating cascading errors when one changes. Thrawn's Scheduling Programming Language treats both as a single interconnected system, generating finished schedules that satisfy educational, coverage, and ACGME requirements across all schedule types at once.

Thrawn's optimization engine enforces ACGME duty hour rules as hard constraints at schedule generation time. This means 80-hour weekly limits, required rest periods, and shift caps are prevented from occurring in the first place — across every X inpatient week and Y ambulatory week. Programs do not need to manually review for violations after publication.

Yes. Continuity clinic assignments are a native input to Thrawn's optimization. Your program's clinic session requirements, patient continuity expectations, and Y week structure are incorporated as constraints alongside block rotations and call schedules. The result is a clinic schedule that never conflicts with inpatient block or call obligations.

Programs send Thrawn their constraints — rotation requirements, resident preferences, ACGME duty hour rules, vacation requests, and X+Y block structure. Thrawn's scheduling specialists and optimization engine produce finished block, call, clinic, and attending schedules. Your chief residents and program director review the completed schedule rather than building it. There is no software to learn or configure.

Thrawn rapidly re-optimizes the affected schedules when an unplanned absence occurs. Rather than manually patching a block rotation and hoping the downstream clinic and call schedules still hold, Thrawn regenerates coverage assignments while preserving fairness and ACGME compliance across the full schedule — preventing a single absence from becoming a program-wide disruption.
