Patient Satisfaction After Total Hip Arthroplasty Is Not Influenced by Reductions in Opioid Prescribing.

BACKGROUND

Opioids have played an important part in post-operative analgesia, but concerns with associated morbidity and the fate of leftover pills have prompted the creation of opioid-sparing protocols. The purpose of this study is to investigate the impact of the implementation of an opioid-sparing protocol on survey-based patient satisfaction scores following total hip arthroplasty (THA).

METHODS

This study is a retrospective review of prospectively collected data on patients who underwent primary THA between November 2014 and July 2019. Inclusion criteria consisted of primary elective THA with complete Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey information. Cohorts were separated based on their date of surgery relative to the start of an institutional opioid-sparing-protocol in October 2018. Discharge prescriptions and refills were recorded on chart review and converted to milligram morphine equivalents (MME) for comparison between different opioids. HCAHPS results were analyzed for percentage of "top box" ratings for comparison between the 2 groups.

RESULTS

In total, 1003 patients met inclusion criteria: 804 pre-protocol and 199 post-protocol. Mean length of stay decreased from 1.74 ± 1.03 to 1.50 ± 1.11 days (P < .001). Pre-operative Visual Analog Scale pain decreased from 7.00 ± 2.30 to 6.41 ± 2.66 (P = .011) as did the rate of opioid refills (15.6%-9.1%; P = .019). Quantity of opioid medication prescribed upon discharge also decreased from 432 ± 298 to 114 ± 156 MME (P < .001). There was no change in "top box percentages" for satisfaction with pain control (79.7% pre-protocol, 82.1% post-protocol; P = .767). There was a significant increase in proportion of patients reporting top box satisfaction with their overall surgical experience after protocol implementation (88.2%-94.0%; P = .018).

CONCLUSION

A reduction in opioids prescribed after THA is not associated with a decrease in patient satisfaction with regard to pain control, as measured by the HCAHPS survey, nor is it associated with an increase in post-operative opioid refills. LOE: III.

CLINICAL RELEVANCE

This study suggests that HCAHP scores are not negatively impacted by a reduction in post-operative opioid analgesics.
