Comparative Study
The prevalence and economic impact of prescription opioid-related side effects among patients with chronic noncancer pain.
To estimate the prevalence of opioid-related side effects among patients with chronic noncancer pain (CNCP) who initiated opioids and compare healthcare costs of patients with and without side effects using patient survey, medical charts, and claims data. ⋯ Prevalence of opioid-related side effects among patients with CNCP who initiated opioids was substantially higher based on patient survey than from charts or claims. Opioid-related side effects were associated with significantly higher healthcare costs.

Increased methadone use in patients with pain has raised concerns that the effect of methadone on the QT interval duration and the potential risk of torsades de pointes (TdP) has been underestimated. Most studies on prolonged QT intervals by methadone are performed in maintenance patients; however, doses of methadone in pain treatment are much lower. Hardly any studies have prospectively addressed QT interval prolongation by methadone in patients with pain, and this study aims to address this literature gap. ⋯ The study found that in our patients with pain, with relatively low doses of methadone, 5 percent had QTc times ≥500 ms and were thus at serious at risk for TdP. ECGs have to be made in all patients with methadone therapy 1 week after introducing methadone (or after dosage increases).

Multicenter Study
Rationale and design of the Oxycodone Users Registry: a prospective, multicenter registry of patients with nonmalignant pain.
This article describes the rationale and design of the Oxycodone Users Registry (OUR) study and lessons learned during study development and data collection. ⋯ Understanding the rationale, design, and lessons learned from the conduct of the OUR study provides insight that can used in future registry studies.

The Utah Department of Health published the Utah Clinical Guidelines on Prescribing Opioids for Treatment of Pain in 2010. The objective was to evaluate the impact of the Guidelines on provider behaviors such as documentation and use of screening tools. ⋯ System-level changes such as inclusion of screening tools into EMRs will be needed to improve compliance with the Guidelines. Providers find treatment of chronic pain to be challenging and something for which they desire additional training and referral support.
