Abstract:
This correlation predictive research study examined the prediction factors concerning body mass index, alcohol intake and physical functional recovery of hospital length of stay among hip arthroplasty patients using the concept of Roy Adaptation Theory. The sample group consisted of 120 hip arthroplasty patients at orthopedic wards of four tertiary care hospitals in Bangkok, Thailand. Data were collected from May 2020 November 2020. The instruments used in this study consisted of the Alcohol Use Disorder Identification Test and the Cumulated Ambulation Score. Analysis was conducted using descriptive statistics and multiple regression statistics. The findings showed that, female subjects were 76.7% with a mean age of 70.40 years (SD = 14.17), A mean body mass index of 21.67 kg/m² (SD = 2.53) alcohol intake at low risk level ( xˉ = 3, SD = 3.80) physical functional recovery was good ( xˉ = 4.88, SD = 1.28) and a mean of hospital length of stay of 6.59 days (SD = 1.90) Body mass index, alcohol intake and physical functional recovery could predict hospital length of stay of the patients with statistical significance (β = -0.274, 0.193, -0.173, p<0.05, respectively). The researcher recommends that the results of this research can be used as a nursing practice guideline to promote the recovery of patients after hip arthroplasty for reducing complications from long hospitalization and can reduce the patient's hospital length of stay and consist of the policy the hospital service quality development policy.
