RESUMEN
OBJECTIVES: This study examined ninety-day and one-year postoperative healthcare utilization and costs following total knee arthroplasty (TKA) from the health sector and patient perspectives. DESIGN: This study relied on: 1) patient-reported medical resource utilization data from diaries in the Knee Arthroplasty Pain Coping Skills Training (KASTPain) trial; and 2) Medicare fee schedules. Medicare payments, patient cost-sharing, and patient time costs were estimated. Generalized linear mixed models were used to identify baseline predictors of costs. RESULTS: In the first ninety days following TKA, patients had an average of 29.7 outpatient visits and 6% were hospitalized. Mean total costs during this period summed to $3,720, the majority attributed to outpatient visit costs (84%). Over the year following TKA, patients had an average of 48.9 outpatient visits, including 33.2 for physical therapy. About a quarter (24%) of patients were hospitalized. Medical costs were incurred at a decreasing rate, from $2,428 in the first six weeks to $648 in the last six weeks. Mean total medical costs across all patients over the year were $8,930, including $5,328 in outpatient costs. Total costs were positively associated with baseline Charlson comorbidity score (P < 0.01). Outpatient costs were positively associated with baseline Charlson comorbidity score (P = 0.03) and a bodily pain burden summary score (P < 0.01). Mean patient cost-sharing summed to $1,342 and time costs summed to $1,346. CONCLUSIONS: Costs in the ninety days and year after TKA can be substantial for both healthcare payers and patients. These costs should be considered as payers continue to explore alternative payment models.

OBJECTIVE: Knee arthroplasty (KA) is an effective surgical procedure. However, clinical studies suggest that a considerable number of patients continue to experience substantial pain and functional loss following surgical recovery. We aimed to estimate pain and function outcome trajectory types for persons undergoing KA, and to determine the relationship between pain and function trajectory types, and pre-surgery predictors of trajectory types. DESIGN: Participants were 384 patients who took part in the KA Skills Training randomized clinical trial. Pain and function were assessed at 2-week pre- and 2-, 6-, and 12-months post-surgery. Piecewise latent class growth models were used to estimate pain and function trajectories. Pre-surgery variables were used to predict trajectory types. RESULTS: There was strong evidence for two trajectory types, labeled as good and poor, for both Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain and Function scores. Model estimated rates of the poor trajectory type were 18% for pain and function. Dumenci's latent kappa between pain and function trajectory types was 0.71 (95% CI: 0.61-0.80). Pain catastrophizing and number of painful body regions were significant predictors of poor pain and function outcomes. Outcome-specific predictors included low income for poor pain and baseline pain and younger age for poor function. CONCLUSIONS: Among adults undergoing KA, approximately one-fifth continue to have persistent pain, poor function, or both. Although the poor pain and function trajectory types tend to go together within persons, a significant number experience either poor pain or function but not both, suggesting heterogeneity among persons who do not fully benefit from KA.

BACKGROUND: Worry can be conceptualized as a cognitive-affective automatic process initiated in order to address uncertainty and potential personal inadequacies that could result in negative outcomes. The purpose of the current study was to develop a measure of pain-specific worry - the Worry About Pain Questionnaire (WAPQ). METHOD: In study 1, responses of 335 pain-free participants were used to complete an item analysis and exploratory factors analysis to develop and assess the internal structure of the WAPQ. Study 2 included 224 pain-free participants who completed the WAPQ in order to confirm its factor structure, and to examine its relation to the experience of acute experimental pain. In study 3, 137 individuals with persistent pain were asked to complete the WAPQ as well as measures of pain and depressive symptoms. RESULTS: The resulting 15-item measure assesses uncertainties and potential negative outcomes related to the experience of pain. The results of the exploratory and confirmatory factor analyses showed a two-factor structure. Across all studies, the WAPQ was found to be related to measures of pain in clinical and non-clinical samples, acute experimental pain stimuli, as well as pain anxiety, pain catastrophizing, fear of pain, rumination and depressive symptomatology. CONCLUSIONS: The results suggest that the WAPQ is a reliable and valid measure for the assessment of worry about pain that can be used to understand how pain-specific worries are related to the experience and impact of pain across different populations. SIGNIFICANCE: Worry has been assessed in pain populations using measures that assess worry in general. The current study shows a relationship between pain-specific worry and the experience of pain. Further, worry about pain is related to but not synonymous with pain catastrophizing.

OBJECTIVE: To investigate the effects of pain coping skills training (PCST) and a lifestyle behavioral weight management (BWM) program on inflammatory markers and biomarker associations with pain and function in the OA LIFE study. METHOD: Serum samples were available from a subset (N = 169) of the overweight or obese knee OA participants in the OA LIFE study that evaluated: PCST, BWM, combined PCST + BWM, or standard care (SC). Inflammatory markers (hsCRP, IL-1ra, IL-1ß, IL-6, IL-8, TNF-α, TNFRI, TNFRII, and hyaluronic acid (HA)), and adipokines (leptin and adiponectin) were measured before and after the 24-week treatment period. Biomarkers were assessed for effects of treatment and for associations with change in weight, pain and disability (unadjusted and adjusted for age, race, sex, baseline body mass index (BMI), and baseline biomarker concentration). RESULTS: PCST + BWM was associated with significant reductions in hsCRP (P = 0.0014), IL-6 (P = 0.0075), and leptin (P = 0.0001). After adjustment, there was a significant effect of PCST + BWM on changes in leptin (b = -0.19, P = 0.01) and IL-6 (b = -0.25, P = 0.02) relative to SC. Reductions in leptin and IL-6 were significantly correlated with reductions in weight, BMI and Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain; reductions in IL-6 were correlated with improvements in WOMAC and Arthritis Impact Measurement Scales (AIMS) physical function. By mediation analyses, weight loss was responsible for 54% of the change in IL-6 and all of the change in leptin. CONCLUSIONS: OA-related inflammatory markers were reduced by a 24-week combined PCST + BWM intervention. This suggests that the inflammatory state can be successfully modified in the context of a readily instituted clinical intervention with a positive clinical outcome.

The objective was to develop a set of "best practices" for use as a primer for those interested in entering the clinical trials field for lifestyle diet and/or exercise interventions in osteoarthritis (OA), and as a set of recommendations for experienced clinical trials investigators. A subcommittee of the non-pharmacologic therapies committee of the OARSI Clinical Trials Working Group was selected by the Steering Committee to develop a set of recommended principles for non-pharmacologic diet/exercise OA randomized clinical trials. Topics were identified for inclusion by co-authors and reviewed by the subcommittee. Resources included authors' expert opinions, traditional search methods including MEDLINE (via PubMed), and previously published guidelines. Suggested steps and considerations for study methods (e.g., recruitment and enrollment of participants, study design, intervention and assessment methods) were recommended. The recommendations set forth in this paper provide a guide from which a research group can design a lifestyle diet/exercise randomized clinical trial in patients with OA.

OBJECTIVE: Pathological gaits have been shown to limit transfer between potential (PE) and kinetic (KE) energy during walking, which can increase locomotor costs. The purpose of this study was to examine whether energy exchange would be limited in people with knee osteoarthritis (OA). METHODS: Ground reaction forces during walking were collected from 93 subjects with symptomatic knee OA (self-selected and fast speeds) and 13 healthy controls (self-selected speed) and used to calculate their center of mass (COM) movements, PE and KE relationships, and energy recovery during a stride. Correlations and linear regressions examined the impact of energy fluctuation phase and amplitude, walking velocity, body mass, self-reported pain, and radiographic severity on recovery. Paired t-tests were run to compare energy recovery between cohorts. RESULTS: Symptomatic knee OA subjects displayed lower energetic recovery during self-selected walking speeds than healthy controls (P = 0.0018). PE and KE phase relationships explained the majority (66%) of variance in recovery. Recovery had a complex relationship with velocity and its change across speeds was significantly influenced by the self-selected walking speed of each subject. Neither radiographic OA scores nor subject self-reported measures demonstrated any relationship with energy recovery. CONCLUSIONS: Knee OA reduces effective exchange of PE and KE, potentially increasing the muscular work required to control movements of the COM. Gait retraining may return subjects to more normal patterns of energy exchange and allow them to reduce fatigue.

Interest in the use of psychosocial interventions to help older adults manage pain is growing. In this article, we review this approach. The first section reviews the conceptual background for psychosocial interventions with a special emphasis on the biopsychosocial model of pain. The second section highlights three psychosocial interventions used with older adults: cognitive behavioural therapy, emotional disclosure, and mind-body interventions (specifically mindfulness-based stress reduction and yoga). The final section of the paper highlights important future directions for work in this area.

This study examined the comparative efficacy of three interventions: a spouse-assisted coping skills training protocol for patients undergoing a multidisciplinary pain management programme (SA-MPMP), conventional patient-oriented multidisciplinary pain management programme (P-MPMP) and standard medical care (SMC). Thirty-six chronic low back pain (CLBP) patients and their spouses were randomly assigned to one of the three conditions. The SA-MPMP condition consisted of seven, weekly, 2-h, group sessions of training in dyadic pain coping and couple skills, delivered by a clinical psychologist with support of a multidisciplinary team of specialists, to patients together with their spouses. P-MPMP consisted of the SA-MPMP training delivered to the patient only (i.e., no spouse participation and assistance). The SMC condition entailed continuation of routine treatment, entailing medical care only. Data analysis revealed that, at the 12-month follow-up time point, patients receiving SA-MPMP had significant improvements in kinesiophobia and rumination about pain compared to those receiving P-MPMP and SMC. In patients suffering from CLBP, an intervention that combines spouse-assisted coping skills training with a multidisciplinary pain management programme can improve fear of movement and rumination about low back pain.

OBJECTIVE: This study examined factors underlying racial differences in pain and function among patients with hip and/or knee osteoarthritis (OA). METHODS: Participants were n=491 African Americans and Caucasians enrolled in a clinical trial of telephone-based OA self-management. Arthritis Impact Measurement Scales-2 (AIMS2) pain and function subscales were obtained at baseline. Potential explanatory variables included arthritis self-efficacy, AIMS2 affect subscale, problem- and emotion-focused pain coping, demographic characteristics, body mass index, self-reported health, joint(s) with OA, symptom duration, pain medication use, current exercise, and AIMS2 pain subscale (in models of function). Variables associated with both race and pain or function, and which reduced the association of race with pain or function by >or=10%, were included in final multivariable models. RESULTS: In simple linear regression models, African Americans had worse scores than Caucasians on AIMS2 pain (B=0.65, P=0.001) and function (B=0.59, P<0.001) subscales. In multivariable models race was no longer associated with pain (B=0.03, P=0.874) or function (B=0.07, P=0.509), indicating these associations were accounted for by other covariates. Variables associated with worse AIMS2 pain and function were: worse AIMS2 affect scores, greater emotion-focused coping, lower arthritis self-efficacy, and fair or poor self-reported health. AIMS2 pain scores were also significantly associated with AIMS2 function. CONCLUSION: Factors explaining racial differences in pain and function were largely psychological, including arthritis self-efficacy, affect, and use of emotion-focused coping. Self-management and psychological interventions can influence these factors, and greater dissemination among African Americans may be a key step toward reducing racial disparities in pain and function.

INTRODUCTION: The present study aimed to replicate and validate the empirically derived subgroup classification based on the Multidimensional Pain Inventory (MPI) in a sample of highly disabled fibromyalgia (FM) patients. Second, it examined how the identified subgroups differed in their response to an intensive, interdisciplinary inpatient pain management program. METHODS: Participants were 118 persons with FM who experienced persistent pain and were disabled. Subgroup classification was conducted by cluster analysis using MPI subscale scores at entry to the program. At program entry and discharge, participants completed the MPI, Medical Outcomes Study Short Form-36, Hospital Anxiety and Depression Scale and Coping Strategies Questionnaire. RESULTS: Cluster analysis identified three subgroups in the highly disabled sample that were similar to those described by other studies using less disabled samples of FM. The dysfunctional subgroup (DYS; 36% of the sample) showed the highest level of depression, the interpersonally distressed subgroup (ID; 24%) showed a modest level of depression and the adaptive copers subgroup (AC; 38%) showed the lowest depression scores in the MPI (negative mood), Medical Outcomes Study Short Form-36 (mental health), Hospital Anxiety and Depression Scale (depression) and Coping Strategies Questionnaire (catastrophizing). Significant differences in treatment outcome were observed among the three subgroups in terms of reduction of pain severity (as assessed using the MPI). The effect sizes were 1.42 for DYS, 1.32 for AC and 0.62 for ID (P=0.004 for pairwise comparison of ID-AC and P=0.018 for ID-DYS). DISCUSSION: These findings underscore the importance of assessing individuals' differences in how they adjust to FM.

OBJECTIVE: This study examined within-day osteoarthritis (OA)-related pain patterns and associated patient characteristics. METHODS: Participants with physician diagnoses and self-reported symptoms of hand (N=40), hip (N=32), and knee (N=85) OA recorded pain using a handheld computer on one weekday and one weekend day, with ratings beginning immediately after waking, then approximately every 2h following. Pain was rated on a sliding visual analog scale with hidden coding of 1-100. Multivariable linear mixed models examined associations of patient demographic characteristics, enrollment site (Durham VA Medical Center vs Duke University Medical Center), joint site, body mass index, and pain medication use with within-day pain range (maximum minus minimum pain rating) and area under the curve (AUC) of pain ratings, which incorporates the magnitude of all pain measurements. RESULTS: Pain patterns differed substantially across individuals. The sample means of the average, maximum, and minimum weekday pain scores were 35.3, 54.4, and 17.9, respectively. The mean pain range was 36.4, and the mean pain AUC was 564.3 (possible range: 16-1600). Pain scores were similar on weekends. In multivariable mixed models, both knee and hip OA were associated with a greater within-day pain range than hand OA. Only VA enrollment site was associated with a significantly greater pain AUC. CONCLUSION: There is substantial within-day range in OA-related pain. Both pain range and overall within-day magnitude vary according to patient characteristics. Patients' records of within-day pain patterns could be used in clinical encounters to tailor recommendations for the timing of medication use and behavioral strategies.

OBJECTIVE: There is limited information about how morbidly obese osteoarthritis (OA) patients cope with the pain they experience. Pain catastrophizing is an important predictor of pain and adjustment in persons with persistent pain. This may be particularly relevant in the morbidly obese (body mass index [BMI] of 40 kg/m(2) or greater) OA population at risk for increased pain. The present study first examined whether borderline morbidly obese and morbidly obese OA patients report higher levels of pain catastrophizing than a sample of OA patients in the overweight and obese category (BMI between 25 kg/m(2) and 34 kg/m(2)). Next, it examined how pain catastrophizing is related to important indexes of pain and adjustment in borderline morbidly obese and morbidly obese OA patients. METHODS: Participants included 43 individuals with knee OA who were borderline morbidly obese or morbidly obese (BMI of 38 kg/m(2) or greater). Participants completed self-report measures of pain catastrophizing, pain, psychological distress, quality of life, binge eating and eating self-efficacy. RESULTS: The sample of borderline morbidly obese and morbidly obese OA patients reported significantly higher levels of pain catastrophizing (P=0.007) than a comparison sample of overweight and obese OA patients. Results suggested that patients who engaged in a high level of pain catastrophizing reported having much more intense and unpleasant pain, higher levels of binge eating, lower self-efficacy for controlling their eating and lower weight-related quality of life (P<0.05 for all). CONCLUSIONS: Pain catastrophizing is related to pain and adjustment in borderline morbidly obese and morbidly obese OA patients. Clinicians working with this population should consider assessing pain catastrophizing in the patients they treat.

This study evaluated a novel intervention for older osteoarthritis (OA) patients and their spousal caregivers that consisted of standard patient education supplemented by information related to effectively managing arthritis as a couple. Twenty-four female OA patients and their husbands were randomly assigned to either an educational intervention that was targeted at both patient and spouse or to a patient education intervention that was targeted at only the patient. Findings revealed that both interventions were evaluated favorably but the couple intervention was better attended than the patient intervention. In addition, patients in the couple intervention experienced greater increased efficacy in managing arthritis pain and other symptoms. The findings of this pilot study point to the utility of a dyadic intervention approach to management of OA in late life.

The objective of this preliminary study was to evaluate more fully the role of daily spiritual experiences and daily religious/spiritual coping in the experience of individuals with pain due to rheumatoid arthritis (RA). Thirty-five individuals with RA were asked to keep a structured daily diary for 30 consecutive days. The diary included standardized measures designed to assess spiritual experiences, religious and spiritual pain coping, salience of religion in coping, religious/spiritual coping efficacy, pain, mood, and perceived social support. The participants in this study reported having spiritual experiences, such as feeling touched by the beauty of creation or feeling a desire to be closer or in union with God, on a relatively frequent basis. These participants also reported using positive religious and spiritual coping strategies much more frequently than negative religious and spiritual coping strategies. Although most of the variance in these measures was due to differences between persons, each measure also displayed a significant variability in scores from day to day. Indeed, there was just as much (or more) variability in these measures over time as there was variability in pain. Individuals who reported frequent daily spiritual experiences had higher levels of positive mood, lower levels of daily negative mood, and higher levels of each of the social support domains. Individuals who reported that religion was very salient in their coping with pain reported much higher levels of instrumental, emotional, arthritis-related, and general social support. Coping efficacy was significantly related to pain, mood, and social support in that on days that participants rated their ability to control pain and decrease pain using spiritual/religious coping methods as high, they were much less likely to have joint pain and negative mood and much more likely to have positive mood and higher levels of general social support. Taken together, these results suggest that daily spiritual experiences and daily religious/spiritual coping variables are important in understanding the experience of persons who have RA. They also suggest that newly developed daily diary methods may provide a useful methodology for studying religious and spiritual dimensions of living with arthritis.
RESUMEN
OBJECTIVES: The purpose of this study was 3-fold: 1) to assess the feasibility of a daily diary for use with children with juvenile rheumatic disease (JRD), 2) to describe daily variation in mood, stressful events, and symptoms in children with JRD, and 3) to examine the extent to which daily mood and daily stressful events predict daily symptoms in children with JRD. METHODS: Twelve children with JRD completed a daily booklet for 7 days. The daily booklet included measures of daily mood, daily stressful events, daily symptoms, and daily function. The children also completed a visual analog scale for pain and the Children's Depression Inventory. RESULTS: Subjects showed good compliance with scheduled completion and return of the daily diaries. Results indicated that children with JRD showed variability in daily mood, frequency of daily stressful events, and daily symptoms across days. Multilevel fixed effects models showed that more negative daily mood and more daily stressful events significantly predicted increased reports of fatigue, stiffness, and cutting back on daily activities. Negative daily mood also correlated with increases in daily reported pain. CONCLUSIONS: These results indicate that daily diary research is both feasible and potentially informative in children with JRD. Our data emphasize the need for further investigation into the role of daily mood and daily stressful events on disease course in JRD.

Individuals who have pain engage in certain pain-related behaviors that tend to communicate their pain to others. There is growing recognition that the careful observation of such pain behaviors is an important component of a comprehensive pain assessment. This article provides an overview of the current status of behavioral observation methods used to assess pain behavior. The first half of this article describes and evaluates the most commonly used pain behavior observation methods. These include self-observation methods such as activity diaries, and direct observation methods such as the use of standard behavior sampling methods and naturalistic observation methods. The second half of the article discusses several important future clinical and research applications of pain behavior observation methods. The need to develop practical, clinical methods for incorporating pain behavior observation methods into practice settings is emphasized. Important future research topics include studying the social context of pain behavior (eg, by examining how spouses respond to displays of pain behavior), examining the predictive validity of pain behavior (ie, how observed pain behaviors predict future disability and impairment), and identifying pain behavior subgroups within heterogeneous chronic pain populations. Further development and refinement of pain behavior observation methods is likely to increase our understanding of the varied ways that patients adapt to persistent pain.

In this study, pain during mammography in women treated conservatively for breast cancer was examined. It studied pain intensity and its relation to a variety of demographic, medical, and pain coping variables as well as to objective measures of breast compression. Ninety-nine women, treated with lumpectomy (with or without radiation) and undergoing follow-up screening mammography, were asked about strategies they use to cope with everyday pain and then were asked to report pain experienced during the mammogram. Treated and untreated breasts were rated separately and compared with a sample of 125 control women with no history of breast cancer. Women reported significantly greater pain in the treated breast (41% greater than the untreated breast and 32% greater than the control group). There was no consistent relationship between mammography pain and pain coping. Average intensity of pain at last mammogram was the best predictor of pain in both breasts. Women treated conservatively for breast cancer experience significantly greater pain during mammography of their treated breast. Radiologists and technologists can identify women at risk for a painful mammogram by asking about the pain at last mammogram. By applying pain-reducing interventions, they might be able to make the mammography experience more tolerable for these women.
RESUMEN
OBJECTIVE: To evaluate the long-term effects of a spouse-assisted coping skills intervention in patients with osteoarthritis (OA) of the knees, and to evaluate how pre- to posttreatment changes in marital adjustment and self-efficacy relate to long-term improvements in pain, psychological disability, physical disability, pain coping, and pain behavior. METHODS: A followup study was conducted with 88 OA patients who had been randomly assigned to 1 of 3 treatment conditions: 1) spouse-assisted coping skills training (spouse-assisted CST), 2) a conventional CST intervention with no spouse involvement, and 3) an arthritis education-spousal support (AE-SS) control condition. To evaluate long-term outcome, comprehensive measures of self-efficacy, marital adjustment, pain, psychological disability, physical disability, pain coping, and pain behavior were collected from these individuals at 6 and 12 months posttreatment. RESULTS: Data analysis revealed that, at 6-month followup, patients in the spouse-assisted CST condition scored higher on measures of coping and self-efficacy than those in the AE-SS control group. At 6-month followup, patients who received CST without spouse involvement showed a significantly higher frequency of coping attempts and reported higher levels of marital adjustment than those in the AE-SS control group. At 12-month followup, patients in the spouse-assisted CST condition had significantly higher overall self-efficacy than those in the AE-SS control condition. In addition, patients in both the spouse-assisted CST and CST only conditions tended to show improvements in physical disability at the 12-month followup. Individual differences in outcome were noted at the 12-month followup. Patients in the spouse-assisted CST condition who reported initial (pre- to posttreatment) increases in marital adjustment had lower levels of psychological disability, physical disability, and pain behavior at 12-month followup. However, for patients in the conventional CST and AE-SS control conditions, increases in marital adjustment occurring over the initial phase of treatment were related to increases in pain and decreases in scores on the Pain Control in Rational Thinking factor of the Coping Strategies Questionnaire. Finally, patients in the spouse-assisted CST condition who showed pre- to posttreatment increases in self-efficacy were more likely to show decreases in pain, psychological disability, and physical disability at 12-month followup. CONCLUSIONS: These findings suggest that spouse-assisted CST can enhance self-efficacy and improve the coping abilities of OA patients in the long term. Individual differences in the long-term outcome of spouse-assisted CST were noted, with some patients (those showing increases in marital satisfaction and self-efficacy) showing much better outcomes than others.

PURPOSE: To compare three equations developed to predict VO2 among patients diagnosed with one of two chronic diseases: essential hypertension (HTN), and fibromyalgia (FM). The equations included the American College of Sports Medicine (ACSM) equation, the FAST equation developed from the Fitness and Arthritis in Seniors Trial (FAST), and an equation developed by Foster et al. METHODS: One hundred twenty-two HTN subjects and 68 FM subjects completed a maximum exercise test according to the Duke/Wake Forest protocol. Measured peak VO2 was then compared with the VO2 predicted by the ACSM, FAST and FOSTER equations, using several statistical methods. RESULTS: The ACSM equation overpredicted peak VO2 in the HTN group by 10.0 +/- 4.0 mL/kg-1/min-1, and in the FM group by 8.6 +/- 4.9 mL/kg-1/min-1 (P < 0.0001). The FAST equation, however, underestimated peak VO2 by 1.5 +/- 4.2 mL/kg-1/min-1 (P < 0.01) and 1.0 +/- 3.3 mL/kg-1/min-1 (P < 0.0001) in the HTN and FM groups, respectively. The FOSTER equation overestimated peak VO2 by 2.3 +/- 3.6 mL/kg-1/min-1 in the HTN group and by 2.1 +/- 3.5 mL/kg-1/min-1 in the FM group (P < 0.0001). A large degree of variability was found for each of the equations. CONCLUSION: Results of this investigation indicate that all three equations produced peak VO2 values that were statistically different from measured values. Although the ACSM equation overestimated VO2 by more than 2 metabolic equivalents (METs) in each patient group, both the FAST and FOSTER equations produced differences that were less than 1 MET. Further research is needed to examine the FAST and FOSTER equations among other patient populations and with other exercise protocols.
