To evaluate the feasibility and effectiveness of a multifaceted educational intervention to improve the opioid prescribing practices of rural family physicians in a remote First Nations community. ⋯ Multifaceted education and consultant support might play an important role in improving family physician comfort with opioid prescribing, and could improve the treatment of chronic pain while minimizing the risk of addiction.

Randomized Controlled Trial Comparative Study
Patients who display protective pain behaviors are viewed as less likable, less dependable, and less likely to return to work.
In the present study, participants (ie, observers) watched video sequences of patients with chronic back pain performing a physically demanding lifting task. Participants were asked to make judgments about patients' levels of pain and readiness to work. For each patient, observers were also asked to make judgments about personality traits relevant to work performance and employment. ⋯ Analyses also revealed that patients displaying protective pain behaviors were perceived as being significantly less likable, less dependable, and less ready to work than patients displaying other forms of pain behavior. Discussion addresses the processes by which pain behaviors might influence observers' judgments about patients' personality traits and readiness to work. Implications of the present findings for clinical practice and the management of patients presenting with pain conditions are also discussed.

Randomized Controlled Trial
Chronic postthoracotomy pain and health-related quality of life.
Pain after thoracotomy is common. The objective of this study was to assess whether pain 3 months postthoracotomy negatively impacts quality of life. ⋯ Pain is commonly reported at 3 months after elective thoracotomy but is generally mild, shows improvement with time, and does not usually require opioid analgesics. Patients who experience postthoracotomy pain at 3 months are at risk for significantly decreased physical functioning and vitality, but are not at risk for significantly decreased social, emotional, or mental health functioning compared with patients who do not experience postthoracotomy pain at 3 months.

New proposals for the International Classification of Diseases-11 revision of pain diagnoses.
The representation of pain diagnoses in current classification systems like International Classification of Diseases (ICD)-10 and Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV does not adequately reflect the state of the art of pain research, and does not sufficiently support the clinical management and research programs for pain conditions. Moreover, there is an urgent need to harmonize classification of pain syndromes of special expert groups (eg, International Classification of Headache Disorders) and general classification systems (eg, ICD-11, DSM-V). Therefore, this paper summarizes new developments, and proposals for pain diagnoses in revised classification systems. A qualitative review of the literature concerning new proposals for classification of pain syndromes that are based on consensus groups was conducted. Selected proposals of national and international pain societies that are based on consensual processes are presented. These proposals can be condensed to be used in ICD-11 classification. The benefits of considering multidimensional and transdiagnostic processes for the classification process are also outlined. The manuscript provides options how to transform current pain-specific classification proposals to the revision of ICD-11. ⋯ Pain research and expertise must be more visible in the ICD-11 revision process. A general category for pain diagnoses as well as specific pain diagnoses under existing categories of organ-specific sections are needed.

Timing of assessment of psychological construct is controversial and results differ based on the model of pain induction. Previous studies have not used an exercise-induced injury model to investigate timing of psychological assessment. Exercise-induced injury models may be appropriate for these investigations because they approximate clinical pain conditions better than other experimental stimuli. In this study we examined the changes of psychological constructs over time and determined whether timing of assessment affected the construct's association with reports of pain intensity and disability. One-hundred twenty-six healthy volunteers completed the Fear of Pain Questionnaire (FPQ-III), Pain Catastrophizing Scale (PCS), and Tampa Scale of Kinesiophobia (TSK) prior to inducing muscle injury to the shoulder. The PCS and TSK were measured again 48 and 96 hours postinjury induction. Pain intensity and disability were collected at 48 and 96 hours and served as dependent variables in separate regression models. Results indicated that the FPQ-III had the strongest prediction of pain intensity from baseline to 96 hours. After baseline the PCS and TSK were stronger predictors of pain intensity and disability, respectively. These data provide support for the use of psychological constructs in predicting outcomes from shoulder pain. However, they deviate from the current theoretical model indicating that fear of pain is a consequence of injury and instead suggests that fear of pain before injury may influence reports of pain intensity. ⋯ The current study provides evidence that fear of pain can be assessed prior to injury. Furthermore, it supports that after injury pain catastrophizing and kinesiophobia are independently associated with pain and disability. Overall these data suggest that timing of psychological assessment may be an important consideration in clinical environments.
