Howie C, Mears SC, Barnes CL, et al. - A systematic review was performed to ascertain the existing post-total joint arthroplasty (TJA) readmission calculators and compare the specific elements that comprise their formula. Researchers further assessed the pros and cons of each calculator. Researchers performed a systematic search through three major databases for publications addressing TJA risk stratification tools for readmission, discharge disposition, and early complications using a PRISMA protocol. Among TJA risk calculators, the extensive variation underscores the need for tools with more individualized stratification capabilities and verification. The results considered that transition to outpatient and same-day discharge TJA may preclude or change the need for many of these calculators. Future trials are required to develop more streamlined risk calculator tools that prognosticate readmission and surgical complications.
