Treatments included monotherapy with long-acting opioids (mono-LAOs), monotherapy 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: P
