- W4285590528 abstract "Previous evidence has shown that preoperative hemoglobin is related to poor prognosis after primary total knee arthroplasty. Reviewing cohort research was conducted at the third-level academic medical center in Singapore and involved 2,676 patients. Population statistics, complications, preoperative hemoglobin (Hb) levels, length of hospital stay (LOS), and readmission information of thirty days were obtained. Anemia was defined based on the World Health Organization (WHO). LOS extension was with the definition as no less than six days with >1/75 LOS corresponding to the data. According to the study requirements, we finally collected 2273 patients. We plotted the relationship between hemoglobin levels and length of stay. We analyzed 2273 patients, with 140 cases of Hb ≤ 11.0 g/dL, 831 cases of Hb 11.0–12.9 g/dL, and the other 1320 cases of Hb ≥ 13.0 g/dL. The mean age of patients with prolonged LOS (68.4 ± 8.2 years) was higher than that of patients with familiar LOS (65.9 ± 8.0 years). In addition, patients with extended LOS had higher ASA-PS values, a history of cerebrovascular accidents (CVA), diabetes mellitus (DM), and ischemic heart disease (IHD) ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M1> <mi>P</mi> <mo><</mo> <mn>0.001</mn> </math> ), repeated surgery within 30 days, HB, and operative time (min) ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M2> <mi>P</mi> <mo><</mo> <mn>0.01</mn> </math> ). Variables independently related to increased risk of extended LOS included general anesthesia (GA) (adjusted OR (aOR) 1.4, <math xmlns=http://www.w3.org/1998/Math/MathML id=M3> <mi>P</mi> <mo>=</mo> <mn>0.005</mn> </math> , <math xmlns=http://www.w3.org/1998/Math/MathML id=M4> <mi>P</mi> <mo>=</mo> <mn>0.005</mn> </math> ), CVA (aOR 3.0, <math xmlns=http://www.w3.org/1998/Math/MathML id=M5> <mi>P</mi> <mo><</mo> <mn>0.001</mn> </math> ), DM (aOR 1.4, <math xmlns=http://www.w3.org/1998/Math/MathML id=M6> <mi>P</mi> <mo>=</mo> <mn>0.032</mn> </math> ), and HB < 11 g/dL. Variables increased LOS included HB ≥ 13 g/dL (aOR 0.4, <math xmlns=http://www.w3.org/1998/Math/MathML id=M7> <mi>P</mi> <mo><</mo> <mn>0.001</mn> </math> ) and Hb 11.0–12.9 g/dL (aOR 0.5, <math xmlns=http://www.w3.org/1998/Math/MathML id=M8> <mi>P</mi> <mo>=</mo> <mn>0.001</mn> </math> ). Hb was 14 g/dL, and LOS decreased by at least 0.24 days for each 1 g increase in preoperative Hb before the inflection point (95%CI 0.12 to 0.36, <math xmlns=http://www.w3.org/1998/Math/MathML id=M9> <mi>P</mi> <mo>=</mo> <mn>0.0001</mn> </math> ). Anemia is familiar in patients receiving elective total knee arthroplasty (TKA) in Singapore. Thus, this study describes that the preoperative hemoglobin was associated with length of stay. We found that on the left where HB was 14, length of stay decreased with increased hemoglobin values. We recommend preoperative correction of anemia to determine the diagnosis." @default.
