RESUMO
OBJECTIVES: To identify typology of pain coping in older adults and to see whether the coping types or patterns were associated with pain, physical health, and mental health outcomes. METHODS: Six hundred and fifty six Chinese older adults were recruited on a convenience basis from social centers in Hong Kong. A 14-item Brief Pain Coping Scale (BPCS) was constructed on the basis of the Chronic Pain Coping Inventory. Outcome measures included pain intensity, pain disability, pain-related cognitions, depressive symptoms, health-related quality of life, and health and physical functioning (in terms of chronic illnesses, basic and instrumental activities of daily living, and self-rated health). Coping typology was identified using latent class analysis. RESULTS: A 3-class solution based on BPCS provided the best fit to data. Class 1 used almost all coping strategies on a daily basis, Class 2 used the strategies less frequently, whereas Class 3 adopted few strategies. Yet, Class 3 was basically indistinguishable from Class 1 across the outcome variables, even though the participants had more chronic illnesses and poorer instrumental activities of daily living than those in Class 1. Class 2, however, had the poorest outcome profiles, reporting more pain, disability, depression, and health-related quality of life than the other two classes. The differences in coping could not be explained by the differential effectiveness of coping strategies across groups. CONCLUSION: The way coping was used, and the way it was related to pain, mood, health and functioning outcomes, varied substantially across individuals. Implications for coping skills interventions are discussed.

OBJECTIVE: The Pain Catastrophizing Scale (PCS) measures three aspects of catastrophic cognitions about pain-rumination, magnification, and helplessness. To facilitate assessment and clinical application, we aimed to (a) develop a short version on the basis of its factorial structure and the items' correlations with key pain-related outcomes, and (b) identify the threshold on the short form indicative of risk for depression. DESIGN: Cross-sectional survey. SETTING: Social centers for older people. PARTICIPANTS: 664 Chinese older adults with chronic pain. MEASUREMENTS: Besides the PCS, pain intensity, pain disability, and depressive symptoms were assessed. RESULTS: For the full scale, confirmatory factor analysis showed that the hypothesized 3-factor model fit the data moderately well. On the basis of the factor loadings, two items were selected from each of the three dimensions. An additional item significantly associated with pain disability and depressive symptoms, over and above these six items, was identified through regression analyses. A short-PCS composed of seven items was formed, which correlated at r=0.97 with the full scale. Subsequently, receiver operating characteristic (ROC) curves were plotted against clinically significant depressive symptoms, defined as a score of ≥12 on a 10-item version of the Center for Epidemiologic Studies-Depression Scale. This analysis showed a score of ≥7 to be the optimal cutoff for the short-PCS, with sensitivity = 81.6% and specificity = 78.3% when predicting clinically significant depressive symptoms. CONCLUSIONS: The short-PCS may be used in lieu of the full scale and as a brief screen to identify individuals with serious catastrophizing.

Self-discrepancy occurs when a person feels the failure to fulfill one's hopes or responsibilities. Although self-discrepancy has been widely examined to elucidate patients' chronic pain adjustment, the underlying mechanism is unclear. The present study proposes that the effect of self-discrepancy on pain outcomes is accounted for by psychological inflexibility, which involves the psychological processes that guide behaviors in the pursuit of goals and values. One-hundred patients with chronic pain were recruited from a public hospital. They were invited to participate in a semi-structured interview regarding their self-discrepancy and complete self-reported questionnaires regarding their psychological inflexibility and pain outcomes. The results confirmed that psychological inflexibility partly accounts for the variance observed between self-discrepancy and pain outcomes. The current study provides additional insight into the mechanism underpinning the impact of self-discrepancy on patients' pain adjustment and offers clinical implications regarding the use of acceptance commitment therapy for chronic pain management.

INTRODUCTION: Early screening of physical and psychosocial risk factors has been advocated as a way to identify low back pain (LBP) patients who may develop chronic disability. This study evaluated the predictive validity of a Chinese version of the Orebro Musculoskeletal Pain Questionnaire (OMPQ) in identifying LBP patients at risk of developing poor return-to-work (RTW) outcomes. METHODS: Altogether 241 patients with acute or subacute non-specific LBP agreed to participate, and they were screened at baseline with OMPQ, and evaluated after discharge from physiotherapy (n = 173) with outcome measures including the Roland-Morris Disability Questionnaire (RMDQ), numerical pain score (0-10) and global recovery (0-10). At 1-year follow-up, information on RTW status as well as sick leave duration were obtained. RESULTS: At baseline the OMPQ had a mean score of 112.0 (SD = 26.5). The receiver operator characteristic (ROC) curves of OMPQ scores at 1-year follow-up recorded values of area under the curve of 0.693 for RTW and 0.714 for sick leave duration, which are comparable to those reported in European studies. OMPQ was the only factor that could significantly predict the RTW outcomes, compared to other variables such as the RMDQ scores. CONCLUSION: The results confirmed the predictive validity of the Chinese version of OMPQ in screening LBP patients at risk of developing poor occupational outcomes, and appropriate interventions can be arranged for these high-risk individuals in the rehabilitation process.

OBJECTIVE: To examine the medium-term effects of a group intervention combining exercise and cognitive-behavioral strategies (EC) on older adults with chronic pain. METHOD: One hundred and fifty-two Hong Kong Chinese older adults with chronic pain affecting bones, muscles, and joints were randomized by clinic/social center to receive 10 weekly sessions of EC or pain education (control). The primary (pain intensity) and secondary outcomes (pain disability, pain self-efficacy, pain catastrophizing, pain coping, depressive symptoms, health-related quality of life, and hip and knee strength) were collected at baseline (T1), postintervention (T2), and 3- (T3) and 6-month follow-ups (T4). The trajectories of intervention effects were modeled by EC × time and EC × time2 interaction terms in mixed-effects regression. RESULTS: Significant EC × time and/or EC × time2 interactions were found for pain intensity, pain disability, self-efficacy, and catastrophizing, such that the treatment effect leveled off (pain disability) or diminished (pain intensity and catastrophizing) over time, or continued to increase in a linear fashion (self-efficacy). There was also a treatment main effect on hip/knee muscle strength. Group differences in favor of EC were observed up to 3-month follow-up for pain intensity (d = -0.51) and hip/knee muscle strength (d = 0.38), and up to 6-month follow-up for pain disability (d = -0.60) and self-efficacy (d = 0.52). No group difference was found for catastrophizing at any time point. No treatment effects were found for the other outcomes. CONCLUSION: Older people suffering from chronic pain can benefit from a program incorporating both cognitive-behavioral techniques and physical exercise.

INTRODUCTION: The cognitive model of hope suggests that people with high levels of hope are able to think about the ways to goals (pathways) and motivated to pursue those pathways to reach their goals (agency). We hypothesized that higher levels of hope would be related to lower levels of pain and less psychological distress (ie, anxiety and depression) and better adjustment. OBJECTIVES: This study aims to examine the relationship, if any, between cognition of hope and chronic musculoskeletal pain. METHODS: One hundred and six patients with chronic musculoskeletal pain were recruited by convenient sampling from 2 public hospitals in Hong Kong. We assessed the hope level, psychological distress, and health outcomes by psychometric inventories. RESULTS: Zero-order correlation results showed that hope was inversely associated with psychological distress (ie, anxiety and depression) and positively related to subjective self-efficacy. There was no significant relationship with severity of pain. Patients presented with longer duration of chronic musculoskeletal pain have higher hope level while pain developed after injury on duty have lower hope level. CONCLUSION: The findings of this cross-sectional study highlight the potential importance of hope in understanding adjustment to chronic musculoskeletal pain. Future longitudinal research could help reveal how hope and adjustment interact over the treatment of chronic pain cases.
RESUMO
BACKGROUND: Acute pain services have received widespread acceptance and formal support from institutions and organizations, but available evidence on their costs and benefits is scarce. Although there is good agreement on the provision of acute pain services after many major surgical procedures, there are other procedures for which the benefits are unclear. Data are required to justify any expansion of acute pain services. In this randomized, controlled clinical trial we compared the costs and effects of acute pain service care on clinical outcomes with conventional pain management on the ward. Patients included in the trial were considered by their anesthesiologist to have either arm be suitable for the procedure. METHODS: Four hundred twenty-three patients undergoing major elective surgery were randomized either to an anesthesiologist-led, nurse-based acute pain service group with patient-controlled analgesia or to a control group with IM or IV boluses of opioid analgesia. Both groups were treated with medications to treat opioid-related adverse effects and received the usual care from health professionals assigned to the ward. The main outcome measures were quality of recovery scores, pain intensity measures, global measure of treatment effectiveness, and overall pain treatment cost. Cost-effectiveness acceptability curves were drawn to detect a difference in the joint cost-effect relationship between groups. RESULTS: There was no difference in quality of recovery score on postoperative day 1 between treatment and control groups (mean difference, 0; 95% confidence interval [CI], -0.7 to 0.7; P = 0.94) or in the rate of improvement in quality of recovery score (mean difference, -0.1; 95% CI, -0.4 to 0.1; P = 0.34). The proportion of patients with 1 or more days of highly effective pain management was higher in the acute pain service group than in the control group (86% vs. 75%; P < 0.01). Costs were higher in the acute pain service group (mean difference, US$46; 95% CI, $44 to $48 per patient; P < 0.001). A cost-effectiveness acceptability curve showed that the acute pain service was more cost effective than was control for providing highly effective pain management if the decision maker was willing to pay more than US$546 per patient per 1 day with highly effective treatment. CONCLUSION: In extending the role of the acute pain service to a specific group of major surgical procedures, the acute pain service was likely to be cost effective.

BACKGROUND AND OBJECTIVES: The 22-item Chronic Pain Self-efficacy Scale (CPSS) measures three domains of pain self-efficacy: pain management, physical functioning, and coping with symptoms. This study aims to develop a short form (CPSS-SF) that retains the multidimensional structure of the instrument. RESEARCH DESIGN AND METHODS: Six hundred sixty-four community-dwelling Chinese older adults aged 60-95 years with chronic pain completed a survey. Confirmatory factor analysis (CFA) was conducted on the 22-item CPSS. Regression analyses were performed to examine the items' correlations with criterion variables. After CPSS-SF items were selected, the performance of CPSS-SF subscales in terms of accounting for pain-related outcomes was compared with the full version. RESULTS: CFA supported a modified 3-factor model of the CPSS. On the basis of factor loadings on the 3 dimensions and the items' correlations with pain intensity and pain disability, 11 items were selected for the CPSS-SF, which correlated at .97 with the full version. Regression analyses showed that the associations of the CPSS-SF subscales with pain intensity, pain disability, depressive symptoms, instrumental activities of daily living, and physical and mental health-related quality of life, were indistinguishable from their full-version counterparts. DISCUSSION AND IMPLICATIONS: The CPSS-SF is a valid instrument that can be used in lieu of the full scale. Its availability will facilitate the assessment of pain self-efficacy in research and clinical settings due to its brevity but strong psychometric properties. However, the current evidence is limited to Chinese older adults; more research is needed to ascertain its validity in other age and cultural groups.

Simulation is a method or technique to produce an experience without going through the real event. There are multiple elements to consider for a simulation programme, and technology is only one of the many dimensions. The ultimate goal is to engage learners to experience the simulated scenario followed by effective feedback and debriefing. Simulation is a useful modality to supplement training in real clinical situations because it enables control over the sequence of tasks offered to learners, provides opportunities to offer support and guidance to learners, prevents unsafe and dangerous situations, and creates tasks that rarely occur in the real world. It is also an effective method for interprofessional education. To use simulation effectively for education, particularly interprofessional team training, adult learning theory needs to be applied and effective feedback given. Future development in simulation depends on overcoming issues related to technology, research, cost and faculty development.

Self-efficacy has been consistently found to be a protective factor against psychological distress and disorders in the literature. However, little research is done on the moderating effect of self-efficacy on depressive symptoms in the context of chronic pain. This cross-sectional study aimed to examine if pain self-efficacy attenuated the direct relationship between pain intensity and depressive symptoms, as well as their indirect relationship through reducing the extent of catastrophizing when feeling pain (moderated mediation). 664 community-dwelling Chinese older adults aged 60-95 years who reported chronic pain for at least three months were recruited from social centers. They completed a battery of questionnaires on chronic pain, pain self-efficacy, catastrophizing, and depressive symptoms in individual face-to-face interviews. Controlling for age, gender, education, self-rated health, number of chronic diseases, pain disability, and pain self-efficacy, pain catastrophizing was found to partially mediate the connection between pain intensity and depressive symptoms. Furthermore, the relationship between pain intensity and depressive symptoms was moderated by pain self-efficacy. Self-efficacy was also found to moderate the relationship between pain intensity and catastrophizing and the moderated mediation effect was confirmed using bootstrap analysis. The results suggested that with increasing levels of self-efficacy, pain intensity's direct effect on depressive symptoms and its indirect effect on depressive symptoms via catastrophizing were both reduced in a dose-dependent manner. Our findings suggest that pain self-efficacy is a significant protective factor that contributes to psychological resilience in chronic pain patients by attenuating the relationship of pain intensity to both catastrophizing and depressive symptoms.

OBJECTIVE: The purpose was to review the literature on the economic benefits associated with Acute Pain Service (APS) programs systematically. APSs have received widespread acceptance and formal support from institutions and organizations, but little is known about its economic benefits. METHODS: MEDLINE and other databases were searched for economic evaluations of APSs. The study characteristics and methodological quality was assessed using standardized tools. All costs were adjusted to 2005 US dollars. RESULTS: Ten economic evaluations (involving 14,774 patients) were identified that met eligibility criteria. There were wide variations in study designs, methodological quality, and outcome measures. There was insufficient data to identify which APSs model (anesthesiologist-based/nursing support or nurse-based/anesthesiologist supervised) was more cost-effective. The cost of APSs for surgical patients from direct and indirect effects (improved pain management from education in patients not receiving APS) varied from $2.28 to $5.08/patient/d. The level of evidence to support the cost-savings associated with APSs (shorter duration of intensive care unit and hospital stays) were limited to partial economic analyses. There was insufficient evidence to draw conclusions about the cost-effectiveness and cost-benefit of APSs as the quality of life and patient's willingness to pay for an APS intervention were not measured, respectively. The overall quality of published economic evaluations of APSs was poor. CONCLUSIONS: There is a lack of high-quality economic studies to support the cost-effectiveness and cost-benefits of APSs.

AIM: This 5-year prospective follow-up of women randomized to general anesthesia (GA) with or without a thoracic paravertebral block (TPVB) examined the risk of local recurrence, metastasis and mortality after breast cancer surgery. PATIENTS AND METHODS: A total of 180 patients undergoing modified radical mastectomy were randomized to one of three study groups: standardized GA only; GA with a single-injection TPVB (s-TPVB) and placebo paravertebral infusion after surgery for 72-h; and GA plus with continuous TPVB (c-TPVB) for 72-h postoperatively. Cox proportional models were used to assess the effect of TPVB on long-term outcomes. Equivalence testing was used to help interpret the results. RESULTS: The incidence [95% confidence interval (CI)] of cancer recurrence, metastatic spread and all-cause mortality was 2.3% (0.7-5.4%), 7.9% (4.6-12.6%) and 6.8% (3.6-11.2%), respectively. Four women had cancer recurrence and had metastatic spread. Compared to the GA-only group, the risk of metastatic spread was not different from that of GA with s-TPVB [hazard ratio (HR)=1.11, 95% CI=0.32-3.83) nor from that with GA plus c-TPVB (HR=0.79, 95% CI=0.21-2.96) (p=0.88). Compared to the GA-only group, the risk of mortality was similarly not different from that of the two other groups (HR=2.57, 95% CI=0.66-9.92; and HR=0.66, 95% CI=0.11-3.97, respectively, p=0.15). CONCLUSION: Although the original study was underpowered to properly address long-term outcomes, the results of this analysis suggest that TPVB, administered whether as a single-injection or continuous infusion during the perioperative period, had little to no appreciable effect on local recurrence, metastasis or mortality after breast cancer surgery.

BACKGROUND: Studies have shown that physical interventions and psychological methods based on the cognitive behavioral approach are efficacious in alleviating pain and that combining both tends to yield more benefits than either intervention alone. In view of the aging population with chronic pain and the lack of evidence-based pain management programs locally, we developed a multicomponent intervention incorporating physical exercise and cognitive behavioral techniques and examined its long-term effects against treatment as usual (i.e., pain education) in older adults with chronic musculoskeletal pain in Hong Kong. METHODS/DESIGN: We are conducting a double-blind, cluster-randomized controlled trial. A sample of 160 participants aged ≥ 60 years will be recruited from social centers or outpatient clinics and will be randomized on the basis of center/clinic to either the multicomponent intervention or the pain education program. Both interventions consist of ten weekly sessions of 90 minutes each. The primary outcome is pain intensity, and the secondary outcomes include pain interference, pain persistence, pain self-efficacy, pain coping, pain catastrophizing cognitions, health-related quality of life, depressive symptoms, and hip and knee muscle strength. All outcome measures will be collected at baseline, postintervention, and at 3 and 6 months follow-up. Intention-to-treat analysis will be performed using mixed-effects regression to see whether the multicomponent intervention alleviates pain intensity and associated outcomes over and above the effects of pain education (i.e., a treatment × time intervention effect). DISCUSSION: Because the activities included in the multicomponent intervention were carefully selected for ready implementation by allied health professionals in general, the results of this study, if positive, will make available an efficacious, nonpharmacological pain management program that can be widely adopted in clinical and social service settings and will hence improve older people's access to pain management services.

Committed action is a key component of the psychological flexibility model that recently has been applied in chronic pain settings. Developed within the Western context, the 8-item Committed Action Questionnaire (CAQ-8) demonstrated good psychometric properties. This study aimed to translate the original English version of the CAQ-8 into Chinese (ChCAQ-8) and to assess its reliability, factor structure and concurrent criterion validity. A total of 210 Chinese patients with chronic pain completed the ChCAQ-8, the Chronic Pain Grade, the Pain Catastrophizing Scale, and the depression subscale of the Hospital Anxiety and Depression Scale. Results of confirmatory factor analysis showed both the 2-factor correlated (CFI = .99) and hierarchical (CFI = .98) models met the minimum acceptable fit criterion. The 2 subscales and the entire scale of ChCAQ-8 demonstrated good internal consistency (Cronbach's αs ranging .70-.86). The ChCAQ-8 negative subscale score was significantly correlated with pain intensity, disability, pain catastrophizing, and depression in the expected direction. The ChCAQ-8 positive subscale was significantly correlated with pain castastrophizing and depression. Results of multivariate regression modeling showed the ChCAQ-8 negative subscale predicted depression (std ß = .19, p < .01) and disability (std ß = .14, p < .05), after adjusting for pain intensity, pain duration and pain catastrophizing. Our findings offer preliminary data for the reliability, factorial and concurrent criterion validity of the ChCAQ-8 in the Chinese population. (PsycINFO Database Record

OBJECTIVES: The concept of mental defeat (MD) has been applied to describe the deeper impact of pain on the person's sense of self. It describes an intense psychological reaction to pain, whereby people feel that pain has taken away their autonomy and identity. Although MD has been found to characterize Western individuals who are most distressed and disabled by CP, it is debatable whether the concept can be generalized to the experience of CP patients in other cultures. The present study examined whether MD contributed to the prediction of distress and disability among Hong Kong (HK) Chinese reporting CP. METHODS: Using questionnaires, the present study assessed MD, pain, distress, and disability in a sample of HK Chinese, comprising CP patients seeking specialist treatment and community volunteers with chronic or acute pain but not seeking specialist treatment. RESULTS: MD was found to be elevated in CP patients seeking specialist treatment but not in nontreatment-seeking volunteers with pain of comparable duration and severity. Hierarchical regression indicated that MD was a significant predictor of functioning and distress, over and above the effects of pain severity and other potential demographic confounds. DISCUSSION: These findings provide further evidence that MD is a factor that differentiates treatment-seeking from nontreatment-seeking individuals with CP. They also highlight the potential value of applying this psychological concept to the understanding and treatment of CP in HK Chinese.

IMPORTANCE OF THE FIELD: Selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs) are becoming increasingly used in the treatment of neuropathic pain and fibromyalgia. However, they are not without adverse effects and their efficacy has not been clear because of conflicting evidence. AREAS COVERED IN THIS REVIEW: We have examined the current evidence on the efficacy of SSRIs and SNRIs in the treatment of neuropathic pain and fibromyalgia. Relevant randomized, placebo-controlled studies were identified through a MEDLINE search of English-language literature from January 1990 to December 2009. WHAT THE READER WILL GAIN: The evidence for efficacy of SSRIs in the treatment neuropathic pain is moderate at best. However, SNRIs, venlafaxine and duloxetine have been shown to be effective in the treatment of painful diabetic neuropathy and polyneuropathy. With fibromyalgia, both SSRIs (fluoxetine and paroxetine) and SNRIs (duloxetine and milnacipran) have been shown to improve pain relief, function and quality of life. TAKE HOME MESSAGE: SSRIs and SNRIs may be considered in the treatment of neuropathic pain if treatment with tricyclic antidepressants and anticonvulsants fails, or if there are contraindications to these drugs. There is also sufficient evidence to indicate that SNRIs are effective in the treatment of fibromyalgia and may be considered early in the treatment of fibromyalgia.
