Key result
Higher ASA scores were significantly associated with increased hospital charges, with ASA 4 patients averaging $15,555 and 45.3 services compared to $10,923 and 24.1 services for ASA 2 patients.
Why the study?
Does the preoperative ASA score predict hospital charges and inpatient services in geriatric patients with hip fractures requiring operative fixation?

Does the preoperative ASA score predict hospital charges and inpatient services in geriatric patients with hip fractures requiring operative fixation?
Absolute Event Rate: 15555% vs 10923%
The preoperative ASA score is significantly associated with inpatient hospital charges and the number of services required for geriatric hip fracture patients, allowing for identification of major cost drivers.
May identify high-cost geriatric hip fracture patients via ASA score; leaves open whether risk stratification alters charges or outcomes.
Purpose. To determine if the American Society of Anesthesiologist (ASA) score can be used to predict hospital charges for inpatient services. Materials and Methods. A retrospective chart review was conducted at a level I trauma center on 547 patients over the age of 60 who presented with a hip fracture and required operative fixation. Hospital charges associated with inpatient and postoperative services were organized within six categories of care. Analysis of variance and a linear regression model were performed to compare preoperative ASA scores with charges and inpatient services. Results. Inpatient and postoperative charges and services were significantly associated with patients' ASA scores. Patients with an ASA score of 4 had the highest average inpatient charges of services of $15,555, compared to $10,923 for patients with an ASA score of 2. Patients with an ASA score of 4 had an average of 45.3 hospital services compared to 24.1 for patients with a score of 2. Conclusions. A patient's ASA score is associated with total and specific hospital charges related to inpatient services. The findings of this study will allow payers to identify the major cost drivers for inpatient services based on a hip fracture patient's preoperative physical status.

Thakore et al. (2014) conducted an observational in Hip fracture (n=547). ASA score 4 vs. ASA score 2 was evaluated on Average inpatient charges of services. Higher ASA scores were significantly associated with increased hospital charges, with ASA 4 patients averaging $15,555 and 45.3 services compared to $10,923 and 24.1 services for ASA 2 patients.
