Randomized Controlled Trial
"I Was a Little Surprised": Qualitative Insights From Patients Enrolled in a 12-Month Trial Comparing Opioids With Nonopioid Medications for Chronic Musculoskeletal Pain.
Chronic musculoskeletal pain is a major public health problem. Although opioid prescribing for chronic pain has increased dramatically since the 1990s, this practice has come under scrutiny because of increases in opioid-related harms and lack of evidence for long-term effectiveness. The Strategies for Prescribing Analgesics Comparative Effectiveness (SPACE) trial was a pragmatic 12-month randomized trial comparing the benefits and harms of opioid versus nonopioid medications for chronic musculoskeletal pain. The current qualitative study was designed to better understand trial results by exploring patients' experiences, including perceptions of medications, experiences with the intervention, and whether expectations were met. Thirty-four participants who were purposefully sampled based on treatment group and intervention response participated in semistructured interviews. The constant comparison method guided analysis. Results revealed that participants often held strong beliefs about opioid medications, which sometimes changed during the trial as they gained experience with medications; participants described a wide variety of experiences with treatment effectiveness, regardless of study group or their response to the intervention; and participants highly valued the personalized pain care model used in SPACE. ⋯ SPACE trial results indicated no advantage for opioid over nonopioid medications. Qualitative findings suggest that, for both treatment groups, preexisting expectations and anticipated improvement in pain shaped experiences with and responses to medications. The personalized pain care model was described as contributing to positive outcomes in both groups.

Diverse behavioral cues have been proposed to be useful cues in infant pain assessment, but there is a paucity of evidence on the basis of formal psychometric evaluation to establish their validity for this purpose. We aimed to examine 2 widely used coding systems, the Neonatal Facial Coding System (NFCS) and the Modified Behavior Pain Scale (MBPS), by examining their factor structures with confirmatory factor analysis using a large archival data set. The results indicated that an item-reduced NFCS scale with 3 items produced a 1-factor pain model that maintained the good psychometric properties of the 7-item scale. ⋯ Redefinition of the MBPS with cry as a sole indicator was suggested. This analysis provides 2 new iterations of the NFCS and MBPS that improve construct validity and internal consistency. These shorter versions also improve the feasibility of both measures and increase their potential for clinical use because less time is required for their administration.

The population prevalence of pediatric chronic pain is not well characterized, in part because of a lack of nationally representative data. Previous research suggests that pediatric chronic pain prolongs inpatient stay and increases costs, but the population-level association between pediatric chronic pain and health care utilization is unclear. We use the 2016 National Survey of Children's Health to describe the prevalence of pediatric chronic pain, and compare health care utilization among children ages 0 to 17 years according to the presence of chronic pain. ⋯ In multivariable analysis, chronic pain was not associated with increased odds of primary care or mental health care use, but was associated with greater odds of using other specialty care (odds ratio [OR] = 2.01, 95% confidence interval [CI] = 1.62-2.47; P < .001), complementary and alternative medicine (OR = 2.32, 95% CI = 1.79-3.03; P < .001), and emergency care (OR = 1.62, 95% CI = 1.29-2.02; P < .001). In this population-based survey, children with chronic pain were more likely to use specialty care but not mental health care. The higher likelihood of emergency care use in this group raises the question of whether better management of pediatric chronic pain could reduce emergency department use.

Effect on Health Care Costs for Adolescents Receiving Adjunctive Internet-Delivered Cognitive-Behavioral Therapy: Results of a Randomized Controlled Trial.
The economic burden of pediatric chronic pain is high, with an estimated annual cost of $19.5 billion. Little is known about whether psychological treatment for pediatric chronic pain can alter health care utilization for youth. The primary aim of this secondary data analysis was to evaluate the effect of adjunctive internet cognitive-behavioral therapy intervention or adjunctive internet education on health care-related economic costs in a cohort of adolescents with chronic pain recruited from interdisciplinary pain clinics across the United States. ⋯ Results indicated that the rate of change in health care costs over time was not significantly different between the internet cognitive-behavioral therapy intervention and adjunctive internet education groups. Further research is needed to replicate these findings and determine patterns and drivers of health care costs for youth with chronic pain evaluated in interdisciplinary pain clinics and whether psychological treatments can alter these patterns. This trial was registered at clinicaltrials.gov (identifier NCT01316471).

The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is one of the most commonly and widely used behavioral observation pain scales. The aim of this study was to test the psychometric and practical properties of the FLACC scale to quantify procedural pain in infants and young children. Twenty-six clinicians independently applied the FLACC scale to segments of video collected from 100 children aged 6 to 42 months undergoing a procedure. ⋯ Correlations between FLACC and Visual Analog Scale observer pain and distress were good (r = .74 and r = .89, respectively). This study supports the reliability and sensitivity of the FLACC scale for procedural pain assessment. However, the circumstances of procedures interfered with application of the scale and the findings question the capacity of the scale to differentiate between pain- and nonpain-related distress.
