Effects of socioeconomic burden on opioid use following total shoulder arthroplasty

Preoperative opioid users experience worse outcomes and higher complication rates compared to opioid-naïve patients following shoulder arthroplasty. This study evaluates the effects of socioeconomic status, as measured by the Distressed Communities Index (DCI), on pre- and postoperative opioid use and its influence on clinical outcomes such as readmission and revision surgery.

A retrospective review of patients who underwent primary shoulder arthroplasty (Current Procedural Terminology code 23472) from 2014 to 2022 at a single academic institution was performed. Exclusion criteria included arthroplasty for fracture, active malignancy, and revision arthroplasty. Demographics, Charlson Comorbidity Index, DCI, and clinical outcomes including 90-day readmission and revision surgery were collected. Patients were classified according to the DCI score of their zip code. Using the Prescription Drug Monitoring Program database, patient pre- and postoperative opioid use in morphine milligram equivalents was gathered.

Individuals from distressed communities used more opioids within 90 days preoperatively compared to patients from prosperous, comfortable, mid-tier, and at-risk populations, respectively. Patients from distressed communities also used significantly more opioids within 90 days postoperatively compared with prosperous, comfortable, and mid-tier, respectively. Of patients from distressed communities, 35.1% developed prolonged opioid use (filling prescriptions >30 days after surgery), significantly more than all other cohorts. Among all patients, 3.5% were readmitted within 90 days and were more likely to be prolonged opioid users (38.9 vs. 21.3%, P < .001). Similarly, 1.5% of patients underwent revision surgery. Those who underwent revision were significantly more likely to be prolonged opioid users (38.2 vs. 21.7%, P = .002).

Shoulder arthroplasty patients from distressed communities use more opioids within 90 days before and after their surgery and are more likely to become prolonged opioid users, placing them at risk for readmission and revision surgery. Identifying patients at an increased risk for excess opioid use is essential to employ appropriate strategies that minimize the detrimental effects of prolonged use following surgery.
