There were statistically significant baseline differences between responders and non-responders (patients lost to follow-up), but differences were small and not clinically relevant. PROMs were not significantly different between 1- and 2-year time points for THA and TKA. Minimal demographic or baseline differences between responders and non-responders suggest a representative sample. These data support a minimum follow-up of 1year for studies with PROMs as the primary outcome variable following THA and TKA. These data support a minimum follow-up of 1 year for studies with PROMs as the primary outcome variable following THA and TKA. Accurate identification of patients at risk of blood transfusion can reduce complications and improve institutional resource allocation. Probabilistic models are used to detect risk factors and formulate patient blood management strategies. Whether these predictors vary among institutions is unclear. We aimed to identify risk factors among our patients who underwent total hip (THA) or knee (TKA) arthroplasty, and combine these predictors to improve our model. We retrospectively assessed risk factors among 531 adults who underwent elective THA or TKA from January 2016 to November 2018. Using relevant surgical and patient characteristics gathered from electronic medical records, we conducted univariable and multivariable analyses. For our logistic regression model, we measured the impact of independent variables (age, gender, operation type (THA or TKA) and preoperative hemoglobin concentration) on the need for a transfusion. Of the 531 patients, 321 had THA (uncemented) and 210 had TKA. For the selected tion. Level 3, retrospective cohort study. Level 3, retrospective cohort study.
