Routine Type and Screens Are Unnecessary for Primary Total Hip and Knee Arthroplasties at an Academic Hospital.


ABSTRACT: Background: Despite decreasing transfusion rates, routine type and screens are frequently used before primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). The aims of this study were to characterize transfusion rates and identify any factors that affect the likelihood of transfusion to determine if it is safe to discontinue routine preoperative type and screens at an academic hospital.

Methods: A retrospective chart review was performed for all patients who underwent primary THA or TKA in 2019 at an academic institution by a fellowship-trained arthroplasty surgeon. Data on preoperative type and screens, transfusion rates, bleeding disorders, and anticoagulation status were obtained. Patients were considered to have a preoperative type and screen if it was performed within 30 days before surgery.

Results: Overall, 379 patients were included in the study. Of these, 210 underwent primary THA and 169 underwent primary TKA. Four patients received transfusions during their hospitalization for a cumulative transfusion rate of 1.06%. No patients received an intraoperative transfusion. One (0.59%) patient received a postoperative transfusion after TKA, and 3 (1.43%) patients received a postoperative transfusion after THA. The mean preoperative hemoglobin of the 4 transfused patients was 10.8 g/dL.

Conclusions: In summary, performing a preoperative routine type and screen is likely unnecessary at academic medical centers. Consideration for obtaining a type and screen may include complex primary surgeries or when patients have preoperative hemoglobin of less than 11 g/dL. Ultimately, preoperative type and screen should be considered on a case-by-case basis using clinical judgment.
