Risk Factors for Post-Operative Blood Transfusion Following Total Knee Arthroplasty.

Conclusions: In a cohort of patients undergoing primary TKA in 2015, history of COPD, black race, operative time, steroid use, bleeding disorder, lack of functional independence and ASA class 3-4 were independent predictors of need for blood transfusion. Additionally, we found that patients who received transfusion demonstrated a significantly higher rate of the following: any complication, pneumonia, urinary tract infection, septic shock, deep vein thrombosis, renal insufficiency, cardiac arrest, myocardial infarction, unplanned readmission, reoperation and mortality. Presence of these risk factors in TKA patients could represent an indication for hemoglobin monitoring post-operatively.Level of Evidence: IV. PMID: 32742211 [PubMed - in process]
