Hip Replacement in a High Volume Community Hospital: Effect on Length of Stay and Hospital Cost

Anne Arundel Health System Research Institute

Overview

The investigators propose to evaluate and compare the percentage of patients who are able to be discharged in less than 3 days after undergoing total hip arthroscopy through either a direct anterior or posterior approach, utilizing the identical post operative protocol. The investigators also propose to evaluate the costs associated with the two different approaches to hip replacement in the same group of patients. Post operative resource utilization, discharge disposition, and pain medicine requirement will also be evaluated.

The investigators hypothesize that a higher proportion of patients treated with the direct anterior approach for hip replacement will be able to leave the hospital in less than 3 days when compared with a less invasive posterior approach. Secondly, decreased length of stay associated with the procedure may reduce hospital costs.

Outcomes

Primary Outcomes

Length of Hospital Stay

The length of stay and proportion of patients who went home in less than 3 days will be determined for each group. To evaluate and compare the percentage of patients who are able to be discharged in less than 3 days after undergoing total hip arthroscopy through either a direct anterior or posterior approach, utilizing the identical post operative protocol.

Time frame: Retrospective review of hospital discharge records

Hospital cost

Hospital cost analysis will be undertaken for each group.

Time frame: Retrospective review of utilization records

Secondary Outcomes

Post Operative Pain Medication Utilization

Analysis of post operative pain medicine requirement will be compared for the two groups.

Time frame: After retrospective chart review is complete -- approximately 6 months

Utilization of inpatient physical therapy resources

Utilization of inpatient physical therapy resources and post hospital discharge disposition will be compared for the two groups.

Time frame: Retrospective review -- of hospital discharge
