Abstract

Little is known about the relationship of the American Society of Anesthesiologists Physical Status Classification scores (ASA scores) on patient outcomes following hip fracture surgery in Asian countries. Therefore, this study explored the association of patients' preoperative ASA scores on trajectories of recovery in physical functioning and health outcomes during the first year following postoperative discharge for older adults with hip-fracture surgery in Taiwan. The data for this study was generated from three prior studies. Participants (N = 226) were older hip-fracture patients from an observational study (n = 86) and two clinical trials (n = 61 and n = 79). Participants were recruited from the trauma wards of one medical center in northern Taiwan and data was collected prior to discharge and at 1, 3, 6, and 12 months after hospital discharge. Participants were grouped as ASA class 1-2 (50.5%; ASA Class 1, n = 7; ASA Class 2, n = 107) and ASA class 3 (49.5%, n = 112). Measures for mortality, service utilization, activities of daily living (ADL), measured by the Chinese Barthel Index, and health related quality of life, measured by Medical Outcomes Study Short Form-36, were assessed for the two groups. Generalized estimating equations (GEE) were used to analyze the changes over time for the two groups. During the first year following hip-fracture surgery, ASA class 1-2 participants had significantly fewer rehospitalizations (6%, p = .02) and better scores for mental health (mean = 70.29, standard deviation = 19.03) at 6- and 12-months following discharge than those classified as ASA 3. In addition, recovery of walking ability (70%, p = .001) and general health (adjusted mean = 58.31, p = .003) was also significantly better than ASA 3 participants. There was a significant association of hip-fracture patients classified as ASA 1-2 with better recovery and service utilization during the first year following surgery. Interventions for hip fractured patients with high ASA scores should be developed to improve recovery and quality of life.
