Psychological and Physical Interventions for the Management of Cancer-Related Pain in Pediatric and Young Adult Patients: An Integrative Review

The aim of this study was to systematically review the psychometric properties, interpretability and feasibility of self-report pain intensity measures for children and adolescents for use in clinical trials evaluating pain treatments. Databases were searched for self-report measures of single-item ratings of pain intensity for children aged 3-18 years. A total of 34 single-item self-report measures were found. The measures' psychometric properties, interpretability and feasibility, were evaluated independently by two investigators according to a set of psychometric criteria. Six single-item measures met the a priori criteria and were included in the final analysis. While these six scales were determined as psychometrically sound and show evidence of responsivity, they had varying degrees of interpretability and feasibility. No single scale was found to be optimal for use with all types of pain or across the developmental age span. Specific recommendations regarding the most psychometrically sound and feasible measures based on age/developmental level and type of pain are discussed. Future research is needed to strengthen the measurement of pain in clinical trials with children.

For patients dying of cancer, a visit to the emergency department can be disruptive, distressing and exhausting. Such visits made near the end of life are considered an indicator of poor-quality cancer care. We describe the most common reasons for visits made to the emergency department during the final six months of life and the final two weeks of life by patients dying of cancer. We performed a descriptive, retrospective cohort study using linked administrative sources of health care data. Between 2002 and 2005 in Ontario, 91,561 patients died of cancer. Of these, 76,759 patients made 194,017 visits to the emergency department during the final six months of life. Further, 31,076 patients made 36,600 visits to the emergency department during the final two weeks of life. In both periods, the most common reasons were abdominal pain, lung cancer, dyspnea, pneumonia, malaise and fatigue, and pleural effusion. Many visits made to the emergency department by patients with cancer near the end of life may be avoidable. An understanding of the reasons for such visits could be useful in the development of dedicated interventions for preventing or avoiding their occurrence.

The purpose of this meta-analytic review was to quantify the effects of psychological therapies for the management of chronic pain in youth. Specifically, in this review we updated previous systematic reviews of randomized controlled trials by including new trials, and by adding disability and emotional functioning to pain as treatment outcomes. Electronic searches of the Cochrane Register of Randomised Controlled Trials, MEDLINE, PsycLIT, EMBASE, and the Social Sciences Citation Index were conducted from inception through August 2008. Methodological quality of the studies was assessed, and data extracted on the three primary outcomes of interest. Twenty-five trials including 1247 young people met inclusion criteria and were included in the meta-analysis. Meta-analytic findings demonstrated a large positive effect of psychological intervention on pain reduction at immediate post-treatment and follow-up in youth with headache, abdominal pain, and fibromyalgia. Small and non-significant effects were found for improvements in disability and emotional functioning, although there were limited data on these outcomes available in the included studies. Omnibus cognitive-behavioral therapy, relaxation therapy, and biofeedback all produced significant and positive effects on pain reduction. Studies directly comparing the effects of self-administered versus therapist-administered interventions found similar effects on pain reduction. Psychological therapies result in improvement in pain relief across several different pain conditions in children. Future trials are needed that incorporate non-pain outcome domains, that focus significant therapeutic content on reductions in disability, and that include extended follow-up to better understand maintenance of treatment effects.
