Effect of Pre- and Post-operative Nutritional Status on Length of Hospital Stay after Total Hip Arthroplasty

Abstract

[Purpose] To clarify the relationship between the length of hospital stay and pre- and post-operative nutritional status in postoperative total hip arthroplasty (THA) patients. [Participants and Methods] We investigated the relationship between the number of postoperative hospital days and age, Body Mass Index, Controlling Nutrition Status (CONUT) score, serum albumin (Alb), total protein, and C-reactive protein on postoperative day 5 in 50 patients (6 males, 44 females, mean age 66.6 ± 10.4 years) who underwent primary THA with a diagnosis of hip osteoarthritis. [Results] The CONUT score was normal in 47 patients and mildly defective in 3. Serum Alb (p＜0.05) was significantly related to the number of postoperative hospital days. [Conclusion] Serum Alb on postoperative day 5 may be predictive of prolonged hospitalization after THA for hip osteoarthritis.
