Predicting factors for walking ability of postoperative patients with hemiarthroplasty at Wahidin Sudirohusodo Hospital in Makassar

Abstract

Background: The ability to make early predictors in post-surgery includes health workers preparing patients for outpatient care. The purpose of this study is to determine the factors that influence the ability to walk postoperative hemiarthroplasty patients when patients are admitted. We hypnotized that age, sex, preoperative walking status, time interval between injury to surgery, preoperative hemoglobin level, muscle weakness, muscle atrophy, anxiety level and body mass index would be predictive factors for walking ability post hemiarthroplasty surgery.Method: An descriptive-analytic study with a cross sectional retrospective approach was conducted at the Wahidin Sudirohusodo Hospital in Makassar 2020. Patients with fractures of the proximal femur had undergone hemiarthroplasty surgery and were over 50 years of age at admission from September 2019 to October 2020. Bivariate and multivariate with logistic regression was usedResult: 39 samples according to inclusion criteria were analyzed. Muscle atrophy has a significant correlation with p = 0,04 (p<0,05). Body mass index and muscle atrophy have the most dominant factors for predict walking ability post hemiarthroplasty (EXP (B) 7,282 & EXP (B) 0,083) eventhough not significant statistically (p = 0,116 & p = 0,073)Conclusion: The muscle atrophy variable in this study was the most significant factor in prediction walking ability post hemiarthroplasty surgery. Also, patient with normal BMI will encourage early walk after surgery better than abnormal BMI in the same muscle-wasting condition
