Evaluation of Pain Catastrophizing Scale for surgical referral to pain psychology in patients undergoing spinal surgery.

Background: Chronic pain is an issue that affects over 100 million Americans daily. Acceptance and Commitment Therapy (ACT) has been found to be beneficial for patients with chronic pain by focusing provider efforts on teaching coping mechanisms for pain instead of eliminating the pain entirely. Current studies demonstrate that ACT significantly improves post-operative chronic pain scores and outcomes. Methods: The 200 patients chosen via random generator were collected and presented to (institution) orthopedic spine surgeons along with additional information such as the patients' history of present illness, Visual Analog Scale (VAS) scores, PROMIS-CAT Pain Interference scores, and status of opiate usage. Surgeons were blinded to the PCS cutoff scores. The (institution) orthopedic spine surgeons then identified which patients they would indicate for ACT and their reasoning. Pre-determined PCS score cut-offs were separately used to determine if a patient was indicated for ACT. Results: The effectiveness of this screening tool was based on the frequency at which the surgeons and PCS scores were complimentary. A department epidemiologist assisted in the analysis of the data with the use of a ROC curve. ROC Curve demonstrated an area under the curve of 0.7784 with a Sensitivity of 0.68 and a Specificity of 0.79. The cut point according to Youden's index is 35. The data showed that the PCS is moderately accurate in its ability to distinguish coinciding patients that the [institution] orthopedic spine surgeons referred for ACT. The adjusted cut-point indicates that patients above a PCS of 35 would be referred to ACT by the orthopedic spine surgeons while those below a PCS score of 35 would not be referred. Conclusions: Using the PCS, a referral with the department pain psychologist would occur by [institution] orthopedic spinal surgeons for patients that are deemed at-risk with a score of at least 35. The goal following this study is to perform future investigations regarding PCS and ACT with patients regarding chronic opioid use and postoperative outcomes. Patients who would be referred for help with chronic pain would be compared to PCS-referred patients and non-referred patients. Pre-operative ACT would be compared to patient outcomes post-operatively. The future aim is to use the cut-offs established in this study for experimental design to evaluate if PCS-referred patients have better pain management post-operatively as compared to the control and previously referred patients. Level of Evidence: Level III diagnostic study.

Do cognitive and physical fatigue tasks enhance pain, cognitive fatigue, and physical fatigue in people with fibromyalgia?

OBJECTIVE: Fibromyalgia is a condition characterized by chronic widespread muscle pain and fatigue. The primary objective of this study was to determine if pain, perceived cognitive fatigue, and perceived physical fatigue were enhanced in participants with fibromyalgia compared to healthy controls during a cognitive fatigue task, a physical fatigue task, and a dual fatigue task. METHODS: In total, 24 people with fibromyalgia and 33 healthy controls completed pain, fatigue, and function measures. A cognitive fatigue task (Controlled Oral Word Association Test) and physical fatigue task (Valpar peg test) were done individually and combined for a dual fatigue task. Resting pain, perceived cognitive fatigue, and perceived physical fatigue were assessed during each task using visual analog scales. Function was assessed with shoulder range of motion and grip. RESULTS: People with fibromyalgia had significantly higher increases in pain, cognitive fatigue, and physical fatigue when compared to healthy controls after completion of a cognitive fatigue task, a physical fatigue task, or a dual fatigue task (P < 0.01) with the exception of perceived cognitive fatigue during the cognitive fatigue task. People with fibromyalgia performed equivalently on measures of physical performance and cognitive performance on the physical and cognitive fatigue tasks, respectively. CONCLUSION: These data show that people with fibromyalgia show larger increases in pain, perceived cognitive fatigue, and perceived physical fatigue to both cognitive and physical fatigue tasks compared to healthy controls. The increases in pain and fatigue during cognitive and physical fatigue tasks could influence subject participation in daily activities and rehabilitation.

Health locus of control and self-efficacy predict back pain rehabilitation outcomes.

INTRODUCTION: Chronic back pain treatments have generally been costly and/or ineffective despite advances in medical technology. Patient selection and factors intrinsic to patients, including beliefs and behaviors, have been increasingly looked upon as possible predictive factors for success following multidisciplinary intervention for chronic back pain. The current study investigated the value of using patients' perceived control over health changes (health locus of control) and their perceived ability to engage in pain management behaviors (pain-related self-efficacy) to predict physical and mental health outcomes. METHODS: We retrospectively analyzed 61 patients who completed a two-week multidisciplinary chronic back pain rehabilitation program at our institution between 2007 and 2009. Patient demographics were identified and categorized. Pre- and post-intervention functional surveys, including the Multidimensional Health Locus of Control Form C, Chronic Pain Self-Efficacy Scale, Medical Outcomes Study Short Form-36 Version 2, Beck Depression Inventory-II, and Oswestry Disability Index Version 2, were used to evaluate benefit from back pain intervention and to examine patient factors that may predict physical and mental health outcomes. RESULTS: Participants included 28 males and 33 females, ages 28 to 72, completing chronic back pain rehabilitation. Locus of control, self-efficacy, and physical and mental health demonstrated treatment-related changes, with notable improvements in physical and mental health. Regression analyses examined the value of pre-treatment health locus of control and pain-related self-efficacy as predictors of physical and mental health one month following treatment. Higher internal and lower doctor health locus of control, and higher self-efficacy at baseline predicted higher lift scores one month after treatment (p <. 05; p <. 01; p <. 01, respectively). Higher baseline self-efficacy also predicted better physical functioning (p <. 01) and lower disability (p <. 01) at one month. CONCLUSIONS: In addition to supporting the multiple benefits of multidisciplinary rehabilitation, this study suggests that pain-related self-efficacy and health locus of control may be valuable predictors of treatment benefit for chronic back pain patients. These results provide direction in screening for factors that may maximize the potential to benefit from multidisciplinary intervention for chronic back pain.

The relationship between religion/spirituality and physical health, mental health, and pain in a chronic pain population.

This study sought to better understand the relationship between religion/spirituality and physical health and mental health in 122 patients with chronic musculoskeletal pain. The current study conceptualized religion/spirituality as a multidimensional factor, and measured it with a new measure of religion/spirituality for research on health outcomes (Brief Multidimensional Measure of Religion/Spirituality). Pain patients' religious and spiritual beliefs appear different than the general population (e.g. pain patients feel less desire to reduce pain in the world and feel more abandoned by God). Hierarchical multiple regression analyses revealed significant associations between components of religion/spirituality and physical and mental health. Private religious practice (e.g. prayer, meditation, consumption of religious media) was inversely related to physical health outcomes, indicating that those who were experiencing worse physical health were more likely to engage in private religious activities, perhaps as a way to cope with their poor health. Forgiveness, negative religious coping, daily spiritual experiences, religious support, and self-rankings of religious/spiritual intensity significantly predicted mental health status. Religion/spirituality was unrelated to pain intensity and life interference due to pain. This study establishes relationships between religion/spirituality and health in a chronic pain population, and emphasizes that religion/spirituality may have both costs and benefits for the health of those with chronic pain.
