Health care resource use and cost differences by opioid therapy type among chronic noncancer pain patients. | LitMetric

AI Article Synopsis

Article Abstract

The study assessed 12-month chronic pain (CP)-related health care utilization and costs among chronic noncancer pain (CNCP) patients who initiated various long-term opioid treatments. Treatments included monotherapy with long-acting opioids (mono-LAOs), mono-therapy with short-acting opioids (mono-SAOs), both LAOs and SAOs (combination), and opioid therapy initiated with SAO or LAO and switched to the other class (switch). Using MarketScan claims databases (2006-2012), we identified CNCP patients with ≥90 days opioid supply after pain diagnosis and continuous enrollment 12 months before pain diagnosis (baseline period) and 12 months after opioid start (post-index period). Outcomes included CP-related health care utilization and costs. Among CNCP patients (n=21,203), the cohort distribution was 74% mono-SAOs, 22% combination, 2% mono-LAOs, and 2% switch. During follow-up, the average daily morphine equivalent dose was highest in mono-LAO patients (96.4 mg) compared with combination patients (89.8 mg), switch patients (64.3 mg), and mono-SAO patients (36.2 mg). After adjusting for baseline differences, the mono-LAO cohort had lower total CP-related costs ($4,933) compared with the mono-SAO ($8,604), switch ($10,470), and combination ($15,190) cohorts (all: <0.05). Mono-LAO patients had greater CP-related prescription costs but lower medical costs than the other cohorts during the follow-up period, including lower CP-related hospitalizations (1% vs 11%-20%), emergency department visits (4% vs 11%-18%), and diagnostic radiology use (21% vs 54%-61%) (all: <0.001). Use of pain-related medications and other treatment modalities was also significantly lower in the mono-LAO cohort relative to the other cohorts. CNCP patients using long-term monotherapy with LAOs had the lowest CP-related total health care costs in the 12 months after opioid initiation compared with mono-SAO, switch, or combination patients despite higher opioid daily doses and higher prescription costs. Future research accounting for severity and duration of pain would aid in determining the optimal long-term opioid regimen for CNCP patients.
