Residency scheduling for orthopedic surgery done for you

Thrawn's optimization engine treats PGY-1 through PGY-5 as a single scheduling problem. Each year's rotation requirements, complement constraints, and educational milestones are encoded as constraints in the Scheduling Programming Language. The engine produces a complete block schedule that satisfies every requirement across all five years simultaneously, rather than building each year in isolation and hoping the pieces fit together.

Yes. Required rotation minimums — such as minimum weeks in trauma, pediatric orthopedics, sports medicine, or joint reconstruction — are entered as hard constraints in Thrawn's system. The optimizer will not produce a schedule that violates them. This means program directors and coordinators can audit compliance before the schedule is ever published, rather than discovering gaps at an ACGME site visit.

Call assignments are optimized simultaneously with block and clinic schedules as part of one interconnected system. ACGME duty hour rules — including the 80-hour weekly limit and required rest periods — are enforced at generation time. Night float, weekend, and holiday call is distributed with mathematical equity across residents, removing the perception of favoritism that often follows manual call builds.

Thrawn re-optimizes the affected schedules rapidly when an unplanned absence occurs. Rather than manually patching coverage and risking ACGME duty hour violations or fairness complaints, Thrawn generates alternative coverage assignments that keep the schedule intact and compliant. This is especially important in surgical programs where in-house coverage requirements are strict.

Spreadsheets and tools like Amion require your chief resident or coordinator to build and maintain the schedule manually — there is no optimization, no automated compliance checking, and no coordinated handling of block, call, and clinic schedules together. Thrawn is a done-for-you managed service: your program sends its constraints, and Thrawn's mathematical optimization engine delivers finished, compliant schedules for review. No software to operate, no cascading errors to fix.
