Multicenter Study
A Shortened Version of the Suicide Cognitions Scale for Identifying Chronic Pain Patients at Risk for Suicide.
Research in psychiatric outpatient and inpatient populations supports the utility of the Suicide Cognitions Scale (SCS) as an indicator of current and future risk for suicidal thoughts and behaviors. Designed to assess suicide-specific thoughts and beliefs, the SCS has yet to be evaluated among chronic pain patients, a group with elevated risk for suicide. The purpose of the present study was to develop and test a shortened version of the SCS (the SCS-S). ⋯ Results support the reliability and validity of the SCS-S among chronic pain patients, and suggest the scale may be a useful method for identifying high-risk patients in medical settings.

Randomized Controlled Trial Multicenter Study
Efficacy and Safety of Once-Daily Extended-Release (ER) Hydrocodone in Individuals Previously Receiving ER Morphine for Chronic Pain.
This post hoc analysis examined the effectiveness and safety of hydrocodone bitartrate (HYD) in patients with moderate-to-severe chronic pain who were previously taking extended-release morphine (morphine ER) for pain management. ⋯ The results of this subgroup analysis suggest that rotation from morphine ER to once-daily HYD in patients with moderate-to-severe chronic pain maintains or improves pain relief and does not increase safety concerns.

Multicenter Study Clinical Trial
Efficacy, Safety, and Predictors of Intradiscal Methylene Blue Injection for Discogenic Low Back Pain: Results of a Multicenter Prospective Clinical Series.
Prospective clinical study of intradiscal methylene blue injection for the treatment of lumbar discogenic pain. ⋯ Our findings of 40% positive respondents, and no complications, give reason to set up a randomized, double-blind, placebo-controlled, trial.

Multicenter Study Observational Study
Changes in Quality of Life after 3 months of Usual Care in a Large Sample of Patients with Noncancer Pain: The "QOOL: Quality of Life and Pain" Study.
Large-scale observational studies can provide useful information on changes in health outcomes over time. The aim of this study was to investigate the effect of 3 months of usual care on quality of life (QOL) and pain outcomes in noncancer chronic pain patients managed by pain specialists and to examine factors associated with changes in QOL. This was assessed using the EQ-5D and pain outcomes using the Brief Pain Inventory (BPI). ⋯ The BPI severity summary score improved from a mean (SD) of 6.5 (1.4) to 4.1 (1.7) and the interference summary score from 6.6 (1.5) to 4.2 (1.9). Changes on the BPI severity and interference scores were associated with changes in the EQ-5D Index and thermometer. In conclusion, 3 months of usual care in noncancer pain patients led to substantial improvements in QOL and pain outcomes.

Multicenter Study
Validation of the Short Form of the Brief Pain Inventory (BPI-SF) in Spanish Patients with Non-Cancer-Related Pain.
The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. ⋯ Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference.
