Association of Preoperative Opioid Use With Complication Rates and Resource Use in Patients Undergoing Hip Arthroscopy for Femoroacetabular Impingement

Preoperative opioid use is associated with worse preoperative patient-reported outcomes in hip arthroscopy patients

OBJECTIVES

The purpose of this study was to define the rate of preoperative opioid use among patients undergoing hip arthroscopy, ascertain which clinical factors are associated with opioid use, and assess the effect of preoperative opioid usage on preoperative patient-reported outcome (PRO) measures.

METHODS

A single institution orthopedic registry was retrospectively analyzed for patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) syndrome with or without labral tear between 2015 and 2022. Patients completed Patient-Reported Outcomes Measurement Information System (PROMIS) in six domains, Numeric Pain Scores (NPS), and Musculoskeletal Outcomes Data Evaluation and Management System expectations domain preoperatively. Patients' charts were reviewed to determine demographic factors and identify any active opioid prescription within 6 weeks before surgery. Bivariate analysis was used to determine associations between preoperative opioid use and baseline PROs. Statistically significant bivariate associations were further tested by multivariate analysis to determine independent predictors.

RESULTS

A total of 123 patients were included (age 39.7 ​± ​12.0 years; 87 females; body mass index 27.4 ​± ​5.7 kg/m2). There were 21 patients (17%) using opioids preoperatively. Prior orthopedic or other surgery and lower education level were associated with preoperative opioid use. Patients with preoperative opioid use scored statistically significantly worse compared with those without preoperative opioid use on baseline PROMIS Physical Function (38.6 vs 40.5, p ​= ​0.01), Pain Interference (65.9 vs 60.2, p ​= ​0.001), Fatigue (60.7 vs 51.6, p ​= ​0.005), Social Satisfaction (38.2 vs 43.2, p ​= ​0.007), and Depression (54.2 vs 48.8, p ​= ​0.01). Preoperative opioid use was also associated with statistically significantly worse preoperative NPS for both the operative hip (6.3 vs 4.6, p ​= ​0.003) and whole body (3.0 vs 1.4, p ​= ​0.008). Preoperative opioid use was an independent predictor of worse baseline PROMIS Pain Interference, Fatigue, Social Satisfaction, and NPS for the operative hip.

CONCLUSION

Patients using opioids preoperatively had worse baseline PROs for physical function, pain, social satisfaction, and depression than those not using opioids preoperatively. When controlling for confounding variables, preoperative opioid use was independently predictive of worse baseline pain, fatigue, and social satisfaction.

Prior Diagnosis of Opioid-Related Disorder Is Associated With Higher Medical Resource Utilization Following Primary Hip Arthroscopy: A National Database Study

PURPOSE

To compare adverse events, medical resource utilization, prescribing patterns, and revision surgery rates of patients with opioid-related disorders (ORDs) undergoing primary hip arthroscopy against a propensity-matched group with no opioid-related disorders (NORDs).

METHODS

The TriNetX database was queried between January 2015 and December 2020 using International Classification of Diseases, 10th Revision and Current Procedural Terminology codes to identify patients undergoing primary hip arthroscopy between ages 18 and 70 years. The ORD cohort was propensity matched in a 1:1 ratio to NORD patients based on age, sex, alcohol-related disorders, heart disease, hypertension, metabolic disorders, anxiety disorders, major depressive disorder, diabetes mellitus, and antidepressant prescriptions. Postoperative rates of adverse events and medical resources were compared within 90 days of procedure, prescriptions were compared within 1 year, and revision surgery was compared within 2 years.

RESULTS

A total of 809 ORD patients were propensity matched in a 1:1 ratio to NORD patients. Postoperative adverse events were similar between groups (P = .693). Rates of revision arthroscopy were also similar for both ORD (9.3%) and NORD (8.0%) cohorts (odds ratio [OR], 1.17; 95% confidence interval [CI], 0.83-1.66; P = .377). ORD patients received care from the emergency department, inpatient admission, outpatient visit, and physical therapy evaluations at higher rates. The ORD cohort received a greater amount of new opioid (OR, 2.66; 95% CI, 2.17-3.26; P < .0001) and antidepressant prescriptions (OR, 1.58; 95% CI, 1.26-1.97; P < .0001) compared to NORD patients within 1 year of surgery.

CONCLUSIONS

ORD patients demonstrated similar rates of adverse events and revision surgery when compared to a propensity-matched group of NORD patients undergoing primary hip arthroscopy. However, ORD patients experienced increased rates of emergency department visits and hospitalizations and were prescribed higher rates of opioid and antidepressant prescriptions.

Prescription opioid use increases resource utilization following ventral hernia repair

BACKGROUND

Previous studies showed that preoperative opioid use is associated with increased postoperative opioid use and surgical site infection (SSI) in patients undergoing ventral hernia repair (VHR). Orthopedic surgery literature cites increased resource utilization with opioid use. This study aimed to determine the effect of preoperative opioid use on resource utilization after open VHR.

METHODS

A retrospective institutional review board-approved study of VHRs from a single tertiary care practice between 2013 and 2020 was performed. Medical records, the National Surgical Quality Improvement Program database, and Kentucky All Schedule Prescription Electronic Reporting data were reviewed for patient demographics, comorbidities, dispensed opiate prescriptions, hernia characteristics, and outcomes. Univariate logistic regression analyses assessed the effect of each patient's demographic and clinical characteristics. Multivariate logistic regression models analyzed significant factors from the univariate analyses. The primary outcome was resource utilization measured as readmission, emergency department visit, or >2 postoperative clinic visits within 45 days after VHR.

RESULTS

Overall, 381 patients who underwent VHR were identified; of which 101 patients had preoperative dispensed opioids. Multivariate analysis demonstrated that patient gender at birth, any new-onset SSI, and any preoperative opioid use were associated with increased postoperative resource utilization (odds ratio, 1.76; P = .026).

CONCLUSION

Preoperative opioid use was determined as a risk factor that increased resource utilization after open VHR. An understanding of the drivers of the increased use of resources is essential in developing strategies to improve healthcare value. Future research will focus on strategies to reduce the utilization of resources among patients who use opioids.

Medicaid Insurance Predicts Increased Postoperative Care Encounters Among Patients on Long-Term Opioid Therapy

OBJECTIVE

This study examined the association between insurance type and postoperative unplanned care encounters among patients on long-term opioid therapy prior to surgery.

SUMMARY BACKGROUND DATA

Preoperative long-term opioid therapy is associated with unique risks and poorer outcomes following surgery. To date, the extent to which insurance coverage influences postoperative outcomes in this population remains unclear.

METHODS

Among individuals receiving a supply of greater than 120 total days or at least 10 opioid prescriptions in the year prior to surgery, we examined patients with Medicaid or private insurance who underwent abdominopelvic surgery from 2017 to 2021 across 70 hospitals in the state of Michigan. The primary outcome was unplanned care encounters, defined as an emergency department visit or unplanned readmission within 30 days of discharge from surgery. Multivariable logistic regression was used to assess the likelihood of acute care events with insurance type as the primary covariate of interest.

RESULTS

Among 1212 patients on long-term opioid therapy prior to surgery, 45.6% (n = 553) had Medicaid insurance. Overall, one in eight (n=151) patients met criteria for a postoperative unplanned care encounter within 30 days. The probability of an unplanned encounter was 4.5 percentage points higher among patients with Medicaid insurance compared to private insurance (95% CI: 0.5%, 8.4%).

CONCLUSIONS

Among patients on preoperative long-term opioid therapy, unplanned care encounters were higher among patients with Medicaid when compared to private insurance. While this is likely multifactorial, differences by insurance status may point to disparities in underlying social determinants of health and suggest the need for postoperative care pathways that address these gaps.
