Predictors of depression in a sample of 1,021 primary care patients with osteoarthritis

Change in suicidal ideation after interdisciplinary treatment of chronic pain

OBJECTIVES

To examine suicidal ideation (SI) in individuals with chronic pain, especially change in suicidal thinking after interdisciplinary treatment.

MATERIALS AND METHODS

Consecutive patients (n=250) admitted to a 4-week, group-based chronic pain management program completed measures of pain intensity, functional limitations, depressive symptoms, overall distress, pain catastrophizing, self-perceived burden, and SI at pretreatment and posttreatment.

RESULTS

Before treatment, 30 (12.0%) participants were classified as having a high level of SI, 56 (22.4%) had a low level of SI, and 164 (65.6%) reported none. After treatment, there was a significant reduction in SI and improvements in all other outcomes, but there were still some individuals with high (n=22, 8.8%) or low (n=28, 11.2%) levels at discharge. Patients with high SI at baseline differed from those with no suicidal thinking on pretreatment and posttreatment measures of depression, distress, catastrophizing, and self-perceived burden, but not on pain intensity or functional limitations. Patients high in SI endorsed greater pain catastrophizing and self-perceived burden than those low in suicidal thinking. Sustained SI after treatment was associated with higher baseline levels of suicidal thinking and self-perceived burden to others, as well as a more limited overall response to treatment.

DISCUSSION

SI was common in individuals with chronic pain, although mostly at a low level. Interdisciplinary treatment may result in reduced suicidal thinking; however, some patients continue to express thoughts of self-harm. Future studies could examine processes of change and interventions for treatment-resistant suicidal concerns.

Depression in patients with chronic kidney disease on dialysis in Saudi Arabia

OBJECTIVE

Patients with chronic kidney disease on hemodialysis experience considerable psychological stress due to physical and social changes brought on by illness, increasing the risk of depressive disorder (DD). We examined the prevalence of DD and depressive symptoms, identified treatments for depression, and determined baseline demographic, social/behavioral, physical, and psychological correlates.

METHODS

A convenience sample of 310 dialysis patients in Jeddah, Saudi Arabia, was screened for DD using the Structured Clinical Interview for Depression and for depressive symptoms using the Hamilton Depression Rating Scale (HDRS). Established measures of psychosocial and physical health characteristics were administered, along with questions about current and past treatments. Bivariate and multivariate analyses identified independent correlates of DD and symptoms.

RESULTS

The prevalence of DD was 6.8 % (major depression 3.2 %, minor depression 3.6 %), and significant depressive symptoms were present in 24.2 % (HDRS 8 or higher). No patients with DD were being treated with antidepressant medication, whereas 28.6 % (6 of 21) were receiving counseling. Being a Saudi national, married, in counseling, or having a history of antidepressant were associated with DD in bivariate analyses. Correlates of depressive symptoms HDRS in multivariate analyses were Saudi nationality, marital status, stressful life events, poor physical functioning, cognitive impairment, overall severity of medical illness, and history of family psychiatric problems.

CONCLUSIONS

The prevalence of DD and depressive symptoms is lower in Saudi dialysis patients than in the rest of the world, largely untreated, and is associated with a distinct set of demographic, psychosocial, and physical health characteristics.

Religious involvement is associated with greater purpose, optimism, generosity and gratitude in persons with major depression and chronic medical illness

OBJECTIVE

Religious involvement may help individuals with chronic medical illness cope better with physical disability and other life changes. We examine the relationships between religiosity, depressive symptoms, and positive emotions in persons with major depression and chronic illness.

METHODS

129 persons who were at least somewhat religious/spiritual were recruited into a clinical trial to evaluate the effectiveness of religious vs. secular cognitive behavioral therapy. Reported here are the relationships at baseline between religious involvement and depressive symptoms, purpose in life, optimism, generosity, and gratefulness using standard measures.

RESULTS

Although religiosity was unrelated to depressive symptoms (F=0.96, p=0.43) and did not buffer the disability-depression relationship (B=-1.56, SE 2.90, p=0.59), strong relationships were found between religious indicators and greater purpose, optimism, generosity, and gratefulness (F=7.08, p<0.0001).

CONCLUSIONS

Although unrelated to depressive symptoms in the setting of major depression and chronic medical illness, higher religious involvement is associated with positive emotions, a finding which may influence the course of depression over time.

The relationship between abuse, psychosocial factors, and pain complaints among older persons in Europe

BACKGROUND AND OBJECTIVE

Abuse and pain complaints are common among older persons. However, little is known about relationships between abuse (e.g. psychological) and pain complaints (e.g. backache) among older persons while considering other factors (e.g. depression). Therefore, the aim of this study was to determine these relationships.

MATERIALS AND METHODS

The design was cross-sectional. A total of 4467 women and men aged 60-84 years from Germany, Greece, Italy, Lithuania, Portugal, Spain, and Sweden answered questionnaires regarding various areas such as abuse, mental health (e.g. anxiety) and pain complaints (e.g. backache). The data were examined with bivariate (analyses of variance) and multivariate methods (linear regressions).

RESULTS

The bivariate analyses showed that psychological abuse was connected with all pain complaints; physical with headache and head pressure; sexual with neck or shoulder pain and headache; injury with all complaints (except pain in joints or limbs); financial with pain in joints or limbs and head pressure; and overall abuse (one or more types) with all complaints (except headache). The regressions showed that psychological abuse increased the likelihood of being affected by head pressure and heaviness or tiredness in the legs; physical abuse of being affected by headache and head pressure; financial abuse of being affected by head pressure; and overall abuse of being affected by headache and head pressure. In general, respondents from Sweden and younger (60-64 years) were less affected by the complaints than those from other countries (e.g. Germany) and older (e.g. 70-74 years), respectively. Respondents on medication (e.g. pain killers) were less affected by all pain complaints and those with high social support by pain in joints or limbs. High scores on anxiety and depression and having many diseases increased the likelihood of being affect by all pain complaints.

CONCLUSIONS

Abuse was related with certain pain complaints (e.g. headache), but other factors and in particular mental health and physical diseases impacted on all pain complaints. Medication and partly social support had a positive effect on the pain experience, i.e. the complaints interfered less with for instance the daily-life of the respondents.

The contributors of emotional distress in painful diabetic neuropathy

AIMS

To examine the contribution of demographic, social, clinical and psychological factors to emotional distress in patients with painful diabetic neuropathy (DN).

METHODS

In total, 142 patients with confirmed painful DN underwent detailed clinical and self-assessment measures (Neuropathic Pain Scale, Hospital Anxiety and Depression Scale, Pain Acceptance Questionnaire and Pain Catastrophizing Scale).

RESULTS

The prevalence of emotional distress was 51.4% in this cohort. Age, sex, marital status, employment history, pain intensity, duration of diabetes and the presence of diabetic and non-diabetic complications were significantly correlated to anxiety and depressive symptom scores. Multiple regression analysis confirmed that the presence of catastrophic thinking was an independent contributor to greater symptoms of anxiety and depression. Being young, single and unemployed significantly contributed to greater anxiety symptoms. Pain-related restriction of quality of life was associated with greater depression symptom scores.

CONCLUSIONS

This study found a high prevalence of emotional distress in patients with painful DN. It highlights that the differing independent contributors to anxiety and depressive symptoms are based on an individual's circumstances and experience. We conclude by highlighting the importance of adopting a holistic approach to pain management, incorporating interventions to increase psychological flexibility alongside conventional pharmacological treatments to improve emotional distress in painful DN.

Prevalence of depression and its associated factors among patients attending primary care settings in the post-conflict Northern Province in Sri Lanka: a cross-sectional study

BACKGROUND

In Sri Lanka, civilians in the Northern Province were affected by a long-term armed conflict that ended in 2009. This study aims to describe the prevalence of depression and its associated factors among adult patients attending primary care settings in the Northern Province in Sri Lanka.

METHODS

We report data from a cross-sectional patient morbidity registry established in 16 primary care facilities (12 Divisional Hospitals and 4 Primary Medical Care Units) in four districts of the Northern Province. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depression among all patients aged ≥ 18 years, between March and May 2013. A sample of 12,841 patient records was included in the analysis. A total score of ≥ 10 in the PHQ-9 was considered as major depression. Factors associated with major depression were tested using multivariable logistic regression analysis.

RESULTS

The prevalence of major depression was 4.5% (95% CI: 4.1-4.9) and mild depression was 13.3% (95% CI: 12.7-13.9). The major depression was significantly higher in females than males (5.1% vs. 3.6%) and among unpaid family workers (6.0%) than any other category who earned an income (varied between 1.2% and 3.2%). The prevalence was rising significantly with advancing age, and ranged from 0.3% in the youngest to 11.6% in the elderly.Multivariable regression analysis revealed that the females have a higher risk for major depression than males (OR = 1.4; 95% CI: 1.1-1.7). Older patients were more likely to be depressed than younger patients, OR (95% CI) were 4.9 (1.9-12.5), 5.6 (2.2-14.0), 5.7 (2.3-14.2) and 4.7 (1.8-11.9) for the age groups 25-34, 35-49, 50-64, and ≥ 65 years respectively, in contrast to 18-24 year group. Disability in walking (OR = 7.5; 95% CI: 5.8-9.8), cognition (OR = 4.5; 95% CI: 3.6-5.6), self-care (OR = 2.6; 95% CI: 1.7-4.0), seeing (OR = 2.3; 95% CI: 1.8-3.0), and hearing (OR = 2.0; 95% CI: 1.5-2.5) showed significant associations with depression.

CONCLUSIONS

Depression is a common issue at primary care settings in a post-conflict population, and the elders, women and persons with disability are at a greater risk. Strengthening capacity of primary care facilities and community mental health services is necessary for early detection and management.

Missed opportunities for depression screening in patients with arthritis in the United States

BACKGROUND

Arthritis affects 20 % of the adult US population and is associated with comorbid depression. Depression screening guidelines have been endorsed for high-risk groups, including persons with arthritis, in the hopes that screening will increase recognition and use of appropriate interventions.

OBJECTIVE

To examine national rates of depression and depression screening for patients with arthritis between 2006 and 2010.

PARTICIPANTS AND DESIGN

We used nationally representative cross-sections of ambulatory visits in the United States from the National Ambulatory Medical Care Survey from 2006 to 2010, which included 18,507 visits with a diagnosis of arthritis. When weighted to the US population, this total represents approximately 644 million visits.

MEASUREMENTS

Visits where arthritis was listed among diagnoses. Outcomes were survey-weighted estimates of depression and prevalence of depression screening among patients with arthritis across patient and physician characteristics.

KEY RESULTS

Of the 644,419,374 visits with arthritis listed, 83,574,127 (13 %) were associated with a comorbid diagnosis of depression. The odds ratio for comorbid depression with arthritis was 1.42 (95 % CI 1.3, 1.5). Depression screening occurred at 3,835,000 (1 %) visits associated with arthritis. When examining the rates of depression screening between ambulatory visits with and without arthritis listed, there was no difference in depression screening rates; both were approximately 1 %. There was no difference in screening rates by provider type. Compared to visits with other common, chronic conditions, the prevalence of depression at arthritis visits was high (13 per 100 visits), although the prevalence of depression screening at arthritis visits was low (0.68 per 100 visits).

CONCLUSIONS

Despite the high prevalence of depression with arthritis, screening for depression was performed at few arthritis visits, representing missed opportunities to detect a common, serious comorbidity. Improved depression screening by providers would identify affected patients, and may lead to appropriate interventions such as mental health referrals and/or treatment with anti-depressants.

Clinical evaluation of upper limb function: Patient's impairment, disability and health-related quality of life

Musculoskeletal disorders substantially impacts physical activity, mental state, and quality of life (QOL). Generally, comprehensive assessment of upper limb function requires measures of impairment or disability as well as health-related quality of life. A growing number of outcome instrument have been introduced to evaluate upper limb function and disability, and these measures can be categorized as patient- or clinician-based, and as condition specific or general health-related QOL evaluations. The upper limb outcome instruments reviewed in this article assess different aspect of upper limb conditions, and the measures are affected by differences in cultural, psychological, and gender aspect of illness perception and behavior. Therefore, physician should select/interpret the outcome instruments addressing their primary purpose of research. Information about regional instruments for upper limb condition and health-related QOL in upper limb disorder may help us in decision-making for treatment priority or in interpretation of the treatment outcomes.

Differences in Effectiveness of the Active Living Every Day Program for Older Adults With Arthritis

Objective:

The authors explored whether demographic and psychosocial variables predicted differences in physical activity for participants with arthritis in a trial of Active Living Every Day (ALED).

Method:

Participants (N = 280) from 17 community sites were randomized into ALED or usual care. The authors assessed participant demographic characteristics, self-efficacy, outcome expectations, pain, fatigue, and depressive symptoms at baseline and physical activity frequency at 20-wk follow-up. They conducted linear regression with interaction terms (Baseline Characteristic × Randomization Group).

Results:

Being female (p ≤ .05), less depressed (p ≤ .05), or younger (p ≤ .10) was associated with more frequent posttest physical activity for ALED participants than for those with usual care. Higher education was associated with more physical activity for both ALED and usual-care groups.

Discussion:

ALED was particularly effective for female, younger, and less depressed participants. Further research should determine whether modifications could produce better outcomes in other subgroups.

Undiagnosed mood disorders and sleep disturbances in primary care patients with chronic musculoskeletal pain

OBJECTIVE

The study aims to determine the prevalence of undiagnosed comorbid mood disorders in patients suffering chronic musculoskeletal pain in a primary care setting and to identify sleep disturbances and other associated factors in these patients, and to compare the use of health services by chronic musculoskeletal pain patients with and without comorbid mood disorders.

DESIGN

Cross-sectional study.

SUBJECTS

A total of 1,006 patients with chronic musculoskeletal pain from a representative sample of primary care centers were evaluated.

OUTCOME MEASURES

Pain was measured using a visual analog scale and the Primary Care Evaluation of Mental Disorders questionnaire was used to measure mood disorders.

RESULTS

We observed a high prevalence of undiagnosed mood disorders in chronic musculoskeletal pain patients (74.7%, 95% confidence interval [CI] 71.9-77.4%), with greater comorbidity in women (adjusted odds ratio [OR] = 1.91, 95% CI 1.37-2.66%) and widow(er)s (adjusted OR = 1.87, 95% CI 1.19-2.91%). Both sleep disturbances (adjusted OR = 1.60, 95% CI 1.17-2.19%) and pain intensity (adjusted OR = 1.02, 95% CI 1.01-1.02%) displayed a direct relationship with mood disorders. Moreover, we found that chronic musculoskeletal pain patients with comorbid mood disorders availed of health care services more frequently than those without (P < 0.001).

CONCLUSIONS

The prevalence of undiagnosed mood disorders in patients with chronic musculoskeletal pain is very high in primary care settings. Our findings suggest that greater attention should be paid to this condition in general practice and that sleep disorders should be evaluated in greater detail to achieve accurate diagnoses and select the most appropriate treatment.

Measurement of prevalence of 'major depressive syndrome' among Indian patients attending pain clinic with chronic pain using PHQ-9 scale

Background:

Presence of major depressive syndrome (MDS) in chronic pain patients (CPPs) requires more attention from the clinicians because of its clinical nature, association of suicidal thoughts and their actual completion, and treatment difficulties. The prevalence of MDS among Indian CPPs is not well studied.

Aim:

To determine the prevalence of MDS among Indian CPPs visiting pain clinic.

Materials and Methods:

In this prospective study, 476 patients who attended a pain clinic in a metropolitan city of India for chronic pain (pain more than six months) were included. They were assessed by ‘PHQ-9 depression scale’ for presence of MDS. Intensity of pain was assessed by ‘Visual analogue scale’ (VAS). Patient details (viz. age, sex), duration and site of pain, and scores of PHQ-9 depression scale and VAS, were noted and statistically analyzed.

Results:

146 out of 476 CPPs (30.67%) were found to suffer from MDS. Women were more prone (F: M =3:2) to develop MDS while suffering from chronic pain. Among 146 CPPs who were suffering from MDS, 108 (73.97%) patients also had suicidal thought. The prevalence of suicidal thought among all CPPs was found to be 22.69%. The depression severity was found to be strongly associated with intensity of pain (P = 0.005 < 0.05) but not associated with the duration of pain (P = 0.159 > 0.05) and age of the patient (P = 0.24 > 0.05).

Conclusion:

We found a high prevalence of MDS among CPPs from India and majority of them also harbored suicidal thought. Therefore, for successful outcome in chronic pain management routine psychological assessment in CPPs should be done to exclude the presence of MDS and suicidal thought.

Targeting care: tailoring nonsurgical management according to clinical presentation

International evidence-based guidelines recommend a multitude of nonsurgical treatment options for the management of osteoarthritis. This article summarizes the evidence available for patient characteristics that have been analyzed as potential predictors of response to nonsurgical interventions for patients with hip and knee osteoarthritis. The specific variables targeted for this review include body mass index, psychological factors, muscle strength, tibiofemoral alignment, radiographic changes, and signs of inflammation. Several studies provide moderate to good evidence of potential predictors of response to nonsurgical treatments, and areas for future research are illuminated.

Effect of depressive symptoms on perceived disability in patients with chronic shoulder pain

BACKGROUND

Psychological distress may be an important determinant of perceived disability in patients with chronic musculoskeletal disorders. We evaluated the relationship between depressive symptoms and perceived disability in patients with chronic shoulder pain and quantified the contribution made by depression to perceived disability.

METHODS

In this prospective study, 109 patients with chronic shoulder pain caused by degenerative or inflammatory disorders were evaluated using the Disability of Arm, Shoulder and Hand (DASH) questionnaire and the Center for Epidemiologic Studies-Depression (CES-D) Scale to determine relationships between depressive symptoms and perceived disability in patients with chronic shoulder pain. In addition, pain scores were evaluated using a visual analog scale (VAS) during activity, and range of motion (ROM) and abduction strength (strength) measurements were measured. Multivariate analyses of variance and regression modeling were used to assess the relative contributions made by depressive symptoms (CES-D) and other clinical parameters to patient-perceived disability (DASH).

RESULTS

DASH scores were found to be moderately correlated (0.3 < r < 0.6) with ROM, strength, pain VAS and CES-D; DASH scores were more strongly correlated with CES-D scores than with pain VAS scores or range of motion (r = 0.58; p < 0.001, 0.37; p < 0.001, 0.32; p = 0.04 respectively). Multiple stepwise regression analyses revealed that gender, ROM, pain VAS and CES-D scores independently predicted DASH score and accounted for 43 % of the variance. CES-D score was found to be the strongest predictor of DASH score and accounted for 23 % of the variance.

CONCLUSIONS

Degrees of depressive symptoms were found to be significantly associated with higher symptom scores and greater disability in patients with chronic shoulder pain. Although a large proportion of perceived disability remains unexplained, perceived disability in patients with chronic shoulder pain was found to be strongly influenced by depressive symptoms.

Self-perceived burden in chronic pain: relevance, prevalence, and predictors

Chronic pain is a debilitating condition that can have an impact on various facets of interpersonal functioning. Although some studies have examined the extent to which family members are affected by an individual's chronic pain, none have examined patients' perceptions of feeling that they have become a burden to others. Research on self-perceived burden in different medical populations, such as cancer, amyotrophic lateral sclerosis, and stroke, has shown that it is associated with physical symptoms and, more robustly, with psychological difficulties and concerns. The present study examined the prevalence and predictors of self-perceived burden in a tertiary chronic pain sample. Participants were consecutive patients (N = 238) admitted to an outpatient, interdisciplinary, chronic pain management program at a rehabilitation hospital. At admission, participants completed a battery of psychometric questionnaires assessing self-perceived burden, as well as a number of clinically relevant constructs. Their significant others (n = 80) also completed a measure of caregiver burden. Self-perceived burden was a commonly reported experience among chronic pain patients, with more than 70% of participants endorsing clinically elevated levels. It was significantly correlated with pain intensity ratings, functional limitations, depressive symptoms, attachment anxiety, pain self-efficacy, and caregiver burden. Self-perceived burden was also correlated with an item assessing suicidal ideation. In a hierarchical regression model, depressive symptoms, pain self-efficacy, and adult attachment significantly predicted self-perceived burden after controlling for demographic and pain-related variables. In conclusion, self-perceived burden is a clinically relevant and commonly reported interpersonal experience in patients with longstanding pain.

Religious versus Conventional Psychotherapy for Major Depression in Patients with Chronic Medical Illness: Rationale, Methods, and Preliminary Results

This paper (1) reviews the physical and religious barriers to CBT that disabled medically ill-depressed patients face, (2) discusses research on the relationship between religion and depression-induced physiological changes, (3) describes an ongoing randomized clinical trial of religious versus secular CBT in chronically ill patients with mild-to-moderate major depression designed to (a) overcome physical and religious barriers to CBT and (b) compare the efficacy of religious versus secular CBT in relieving depression and improving immune and endocrine functions, and (4) presents preliminary results that illustrate the technical difficulties that have been encountered in implementing this trial. CBT is being delivered remotely via instant messaging, telephone, or Skype, and Christian, Jewish, Muslim, Buddhist, and Hindu versions of religious CBT are being developed. The preliminary results described here are particular to the technologies employed in this study and are not results from the CBT clinical trial whose findings will be published in the future after the study ends and data are analyzed. The ultimate goal is to determine if a psychotherapy delivered remotely that integrates patients' religious resources improves depression more quickly than a therapy that ignores them, and whether religious CBT is more effective than conventional CBT in reversing depression-induced physiological changes.

Association between pain, radiographic severity, and centrally-mediated symptoms in women with knee osteoarthritis

OBJECTIVE

To examine the relationship between pain, radiographic severity, and a common set of co-occurring centrally-mediated symptoms (fatigue, sleep quality, and depression) in women with knee osteoarthritis.

METHODS

Participants underwent knee radiographs, and had repeated assessments of pain severity and other centrally-mediated symptoms during a 5-day home monitoring period. To examine associations between pain severity (the average of pain over the home monitoring period), measures of osteoarthritis radiographic severity (Kellgren/Lawrence grade, minimum joint space width), centrally-mediated symptoms, and demographics (age) were used. Symptoms of fatigue, sleep efficiency, and depression were used in a composite measure representing centrally-mediated symptoms.

RESULTS

Using a series of linear regression models in which each variable was entered hierarchically (n = 54), the final model showed that 27% of the variance in pain severity was explained by age, radiographic severity, and centrally-mediated symptoms. Centrally-mediated symptoms explained an additional 10% of the variance in pain severity after the other 2 variables were entered.

CONCLUSION

Both radiographic severity and centrally-mediated symptoms were independently and significantly associated with pain severity in women with knee osteoarthritis. In addition to more severe radiographic features, women with higher centrally-mediated symptoms had greater pain severity. Treatments for women with symptomatic knee osteoarthritis may be optimized by addressing both peripheral and central sources of pain.

Suicidal ideation among adults with arthritis: prevalence and subgroups at highest risk. Data from the 2007-2008 National Health and Nutrition Examination Survey

OBJECTIVE

To evaluate the prevalence, correlates, and subgroups at highest risk for suicidal ideation among adults with arthritis.

METHODS

We used data on US adults with arthritis, ages ≥40 years, participating in the 2007-2008 National Health and Nutrition Examination Survey. Suicidal ideation was assessed by item 9 of the Patient Health Questionnaire 9 (PHQ-9). Sociodemographic factors, health behaviors, and comorbid conditions were examined as potential correlates. Depression was measured by the PHQ-8 score (range 1-24). We used random forests to identify subgroups at highest risk for suicidal ideation. To determine if any correlates were unique to arthritis, we compared results to those for persons with diabetes mellitus and cancer.

RESULTS

The prevalence ± SEM of suicidal ideation was 5.6% ± 0.8% among persons with arthritis and 2.4% ± 0.4% among those without. The most important correlates for suicidal ideation in adults with arthritis were depression, anxiety, duration of arthritis, age, income:poverty ratio, number of close friends, pain, alcohol, excessive daytime sleepiness, and comorbidities. Eleven of the 16 most important contributors for suicidal ideation among adults with arthritis were also important for people with diabetes mellitus and cancer. Among persons with arthritis, subgroups at highest risk for suicidal ideation were those with a PHQ-8 score between 18 and 24 and less than 4.5 years of arthritis (96.5%), and those with a PHQ-8 score between 7 and 17, ≥1.24 days of binges/month, and either an income of ≥$45,000/year (85.4%) or an income of <$45,000/year and >3 comorbidities (70.8%).

CONCLUSION

Depression, short duration of arthritis, binge drinking, income, and >3 comorbidities identified subgroups of adults with arthritis at greatest risk for suicidal ideation.

Effectiveness of two evidence-based programs in participants with arthritis: findings from the active for life initiative

OBJECTIVE

Arthritis is the leading cause of disability in the US. Strong evidence suggests that physical activity (PA) is beneficial to those with arthritis. This study examined whether changes in PA and PA-related outcomes from two general evidence-based PA programs (Active Choices [AC] and Active Living Every Day [ALED]) differed in participants with and without arthritis.

METHODS

Active for Life was a 4-year, multicenter, translational initiative that evaluated the effects of AC and ALED on PA and PA-related outcomes. Participants self-reported arthritis, PA, depressive symptoms, perceived stress, and satisfaction with body appearance and function. A subset of participants completed functional fitness tests.

RESULTS

Participants (n = 2,413 AC, n = 3,191 ALED) completed at least one outcome measure; 619 ALED participants completed at least one functional fitness test. Significant improvements in all PA and PA-related outcomes were seen for people with and without arthritis with the exception of depressive symptoms and perceived stress, which only improved in ALED participants. In general, effect sizes were similar for those with and without arthritis.

CONCLUSION

ALED and AC, both general behavioral PA programs, produced positive and meaningful changes in PA and a number of PA-related behaviors in participants with and without arthritis, pointing to the potential appropriateness of these evidence-based programs for people with arthritis.

Subgroups of older adults with osteoarthritis based upon differing comorbid symptom presentations and potential underlying pain mechanisms

Introduction

Although people with knee and hip osteoarthritis (OA) seek treatment because of pain, many of these individuals have commonly co-occurring symptoms (for example, fatigue, sleep problems, mood disorders). The purpose of this study was to characterize adults with OA by identifying subgroups with the above comorbid symptoms along with illness burden (a composite measure of somatic symptoms) to begin to examine whether subsets may have differing underlying pain mechanisms.

Methods

Community-living older adults with symptomatic knee and hip OA (n = 129) participated (68% with knee OA, 38% with hip OA). Hierarchical agglomerative cluster analysis was used. To determine the relative contribution of each variable in a cluster, multivariate analysis of variance was used.

Results

We found three clusters. Cluster 1 (n = 45) had high levels of pain, fatigue, sleep problems, and mood disturbances. Cluster 2 (n = 38) had intermediate degrees of depression and fatigue, but low pain and good sleep. Cluster 3 (n = 42) had the lowest levels of pain, fatigue, and depression, but worse sleep quality than Cluster 2.

Conclusions

In adults with symptomatic OA, three distinct subgroups were identified. Although replication is needed, many individuals with OA had symptoms other than joint pain and some (such as those in Cluster 1) may have relatively stronger central nervous system (CNS) contributions to their symptoms. For such individuals, therapies may need to include centrally-acting components in addition to traditional peripheral approaches.

Development and validation of a 6-day standard for the identification of frequent mental distress

PURPOSE

The goals of the current study were to assess the concurrent validity of a single-item measure of general mental distress with established, multi-item mental health measures used in population-level surveillance and to establish the optimal cutpoint for determining psychological distress (previously identified as frequent mental distress) using recently available data from the Behavioral Risk Factor Surveillance System survey.

METHODS

Data for this study were obtained from the core questionnaire and two optional modules available as part of the 2006 and 2007 Behavioral Risk Factor Surveillance System (BRFSS) surveys. Frequent mental distress (FMD) was identified by the number of days of self-reported poor mental health during the last 30 days. Comparisons of the number of days with poor mental health and positive scores for measures of depression and serious mental illness were calculated to identify the most efficient cutpoint for establishing FMD.

RESULTS

Comparisons of results obtained from ROC analyses using the PHQ-8 and K6 reported 0.867 (95% CI 0.861-0.872) and 0.840 (95% CI 0.836-0.845) of the area under the curve, respectively, suggesting good accuracy. Using the Youden index, 6 days of poor mental health in the past 30 days, rather than the existing 14-day standard, was identified as the point at which the sum of the sensitivity and specificity was greatest.

CONCLUSION

Results from this study suggest that a 6-day standard (FMD-6) can be used as a valid and reliable indicator of generalized mental distress with strong associations to both diagnosable depressive symptomology and serious mental illness.

Association between comorbid depression and osteoarthritis symptom severity in patients with knee osteoarthritis

BACKGROUND

We sought to investigate the reported association between depression and severity of knee osteoarthritis symptoms stratified by radiographic severity of osteoarthritis and to quantify the contribution made by depression to symptom severity.

METHODS

Six hundred and sixty elderly Koreans (sixty-five years or older) were evaluated for radiographic severity of knee osteoarthritis on the basis of the Kellgren-Lawrence grading system and also for symptom severity on the basis of the Western Ontario and McMaster Universities Osteoarthritis Index scales. Patient interviews and a questionnaire that made use of a geriatric depression scale were conducted for the purpose of assessing depressive disorders. Regression analyses were performed to assess the relative contributions by radiographic severity and depression severity to Western Ontario and McMaster Universities Osteoarthritis Index scores and to explore any associations between radiographic severity and the presence of a depressive disorder with regard to the risk of symptomatic knee osteoarthritis. Symptomatic knee osteoarthritis was defined as a Western Ontario and McMaster Universities Osteoarthritis Index score of ≥39.

RESULTS

The presence of a depressive disorder was found to be associated with an increased risk of symptomatic knee osteoarthritis (odds ratio = 5.87 [95% confidence interval, 3.01 to 11.44]). However, the influence of the presence of a depressive disorder was limited to subjects with a radiographic severity of minimal to moderate (Kellgren-Lawrence grade 0 to 3). The presence of a depressive disorder was not associated with the risk of symptomatic knee osteoarthritis in subjects with severe osteoarthritis (Kellgren-Lawrence grade 4).

CONCLUSIONS

This study indicates that the assessment and management of coexisting depression should be integrated with the assessment and management of knee osteoarthritis, particularly when radiographic changes of osteoarthritis in the knee joint are not severe.

Prevalence of anxiety and depression in osteoarthritis: use of the Hospital Anxiety and Depression Scale as a screening tool

The aims of this study are to ascertain the prevalence of anxiety and depressive disorders in an outpatient population with osteoarthritis (OA), examine the interrelationships between severity of OA, pain, disability, and depression, and evaluate the Hospital Anxiety and Depression Scale (HADS) as a screening tool for this population. Patients with lower limb OA were evaluated with the Short Form McGill Pain and Present Pain Index Questionnaires, and a visual analogue scale, WOMAC Osteoarthritis Index-section C, and the HADS. Participants underwent a structured clinical interview by a liaison psychiatrist (AB). X-rays of affected joints were rated for disease severity. Fifty-four patients (42 females; mean age 63.3) were investigated. The prevalence of clinically significant anxiety and/or depression was 40.7% (95% confidence interval (CI), 27.6-55.0%). HADS was a good predictor of anxiety and depression with a sensitivity and specificity of 88% (95%CI, 64% to 99%) and 81% (95%CI, 65% to 92%), respectively. Pain correlated with HADS anxiety and depression scores (e.g. Rank correlation coefficients (Kendall's tau-b) between total HADS scores and Pain VAS scores 0.29; p=0.003). Disability was greater in patients with depression and/or anxiety (e.g. total HADS score; Kendall's rank correlation coefficient tau-b=0.26, p=0.007) OA severity as determined by radiological score was not a good predictor for anxiety nor depression and only weakly associated with disability. Anxiety and depression are very common in OA patients. HADS anxiety was a better predictor of diagnosed anxiety than HADS depression was of diagnosed depression. HADS is a valid and reliable screening instrument for detecting mood disorder, but not a diagnostic tool or a substitute for asking about symptoms of depression. The interrelationship between mental health, pain and disability is strong. We should therefore adopt a multidisciplinary approach to the management of OA.

A longitudinal study to explain the pain-depression link in older adults with osteoarthritis

OBJECTIVE

To evaluate whether osteoarthritis (OA) pain determines depressed mood, taking into consideration fatigue and disability and controlling for other factors.

METHODS

In a community cohort with hip/knee OA, telephone interviews assessed OA pain and disability (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), fatigue (Multidimensional Fatigue Symptom Inventory), depressed mood (Center for Epidemiologic Studies Depression Scale), and covariates (demographics, self-rated health, comorbidity, pain coping, pain catastrophizing, and social support) at 3 time points over 2 years. Drawing on previous research, a path model was developed to test the interrelationships among the key concepts (pain, depression, fatigue, disability) over time, controlling for covariates.

RESULTS

The baseline mean age was 75.4 years; 78.5% of the subjects were women, 37.2% were living alone, and 15.5% had ≥3 comorbid conditions. WOMAC scores indicated moderate OA symptoms and disability. From the final model with 529 subjects, adjusting for covariates, we found that current OA pain strongly predicted future fatigue and disability (both short and long term), that fatigue and disability in turn predicted future depressed mood, that depressed mood and fatigue were interrelated such that depressed mood exacerbated fatigue and vice versa, and that fatigue and disability, but not depressed mood, led to worsening of OA pain.

CONCLUSION

Controlling for other factors, OA pain determined subsequent depressed mood through its effect on fatigue and disability. These effects led to worsening of pain and disability over time. These results support the need for improved pain management in OA to prevent or attenuate the downstream effects of pain on disability and mood.

The Patient Health Questionnaire Somatic, Anxiety, and Depressive Symptom Scales: a systematic review

BACKGROUND

Depression, anxiety and somatization are the most common mental disorders in primary care as well as medical specialty populations; each is present in at least 5-10% of patients and frequently comorbid with one another. An efficient means for measuring and monitoring all three conditions would be desirable.

METHODS

Evidence regarding the psychometric and pragmatic characteristics of the Patient Health Questionnaire (PHQ)-9 depression, generalized anxiety disorder (GAD)-7 anxiety and PHQ-15 somatic symptom scales are synthesized from two sources: (1) four multisite cross-sectional studies (three conducted in primary care and one in obstetric-gynecology practices) comprising 9740 patients, and (2) key studies from the literature that have studied these scales.

RESULTS

The PHQ-9 and its abbreviated eight-item (PHQ-8) and two-item (PHQ-2) versions have good sensitivity and specificity for detecting depressive disorders. Likewise, the GAD-7 and its abbreviated two-item (GAD-2) version have good operating characteristics for detecting generalized anxiety, panic, social anxiety and post-traumatic stress disorder. The optimal cutpoint is > or = 10 on the parent scales (PHQ-9 and GAD-7) and > or = 3 on the ultra-brief versions (PHQ-2 and GAD-2). The PHQ-15 is equal or superior to other brief measures for assessing somatic symptoms and screening for somatoform disorders. Cutpoints of 5, 10 and 15 represent mild, moderate and severe symptom levels on all three scales. Sensitivity to change is well-established for the PHQ-9 and emerging albeit not yet definitive for the GAD-7 and PHQ-15.

CONCLUSIONS

The PHQ-9, GAD-7 and PHQ-15 are brief well-validated measures for detecting and monitoring depression, anxiety and somatization.

The robust association between childhood physical abuse and osteoarthritis in adulthood: findings from a representative community sample

OBJECTIVE

Research suggests a role of early-life trauma in the development of arthritis. This study investigated the relationship between childhood physical abuse and osteoarthritis (OA) while controlling for age, sex, race, and socioeconomic status (SES), in addition to the following types of risk factors for OA: 1) concurrent childhood stressors, 2) adult health behaviors, and 3) depression.

METHODS

Data from the provinces of Manitoba and Saskatchewan were selected from the 2005 Canadian Community Health Survey (n = 13,093). Respondents with missing arthritis data or with arthritis types other than OA were excluded (n = 1,985). Of the 11,108 remaining respondents, 6.9% (n = 854) reported childhood physical abuse by someone close to them, and 10.1% (n = 1,452) reported that they had been diagnosed with OA by a health professional. The regional-level response rate was 84%.

RESULTS

When adjusting for all 3 types of risk factors, a significant association between childhood physical abuse and OA was found (odds ratio [OR] 1.56, 95% confidence interval [95% CI] 1.21-2.00). In contrast, when adjusting for age, sex, race, and SES only, the OR was 1.99 (95% CI 1.57-2.52).

CONCLUSION

The association between childhood physical abuse and OA remained significant, even after controlling for many risk factors that may mediate the relationship. Further research is needed to investigate potential pathways through which arthritis develops as a consequence of childhood physical abuse.

The longitudinal effects of depression on physical activity

OBJECTIVES

It has been posited that depression and sedentary lifestyle have bidirectional relationships. Although the role of baseline physical activity as a risk factor for emerging depression has been recently reviewed, there has been no systematic review of the literature to assess the reverse relationship. We reviewed the results of longitudinal studies in the world's literature that have studied the effect of baseline depression on ensuing levels of physical activity.

MEASURES

MEDLINE, PsycINFO, CINHAL Plus, Health Source: Nursing Academic Edition and Cochrane databases were searched from 1959 to 2008 with a focus on depression, sedentary lifestyle and exercise. Published longitudinal studies in English and more than 100 patients were included.

RESULTS

Eleven studies met our inclusion criteria, eight of which reported that baseline depression was significantly associated with subsequent sedentary lifestyle or poor adherence to the physical exercise regimens recommended by physicians after a coronary event. However, the studies used different depression scales and physical activity outcome measures, and varied a great deal in the range of potential confounders they controlled for. In addition, there were only three studies that were specifically designed to assess the role of baseline depression on the subsequent level of physical activity.

CONCLUSIONS

Baseline depression may be a significant risk factor for development of sedentary lifestyle or decreased level of physical exercise. Future studies should examine mechanisms by which depression may lead to decline in activity.

Sex, gender, and pain: a review of recent clinical and experimental findings

Sex-related influences on pain and analgesia have become a topic of tremendous scientific and clinical interest, especially in the last 10 to 15 years. Members of our research group published reviews of this literature more than a decade ago, and the intervening time period has witnessed robust growth in research regarding sex, gender, and pain. Therefore, it seems timely to revisit this literature. Abundant evidence from recent epidemiologic studies clearly demonstrates that women are at substantially greater risk for many clinical pain conditions, and there is some suggestion that postoperative and procedural pain may be more severe among women than men. Consistent with our previous reviews, current human findings regarding sex differences in experimental pain indicate greater pain sensitivity among females compared with males for most pain modalities, including more recently implemented clinically relevant pain models such as temporal summation of pain and intramuscular injection of algesic substances. The evidence regarding sex differences in laboratory measures of endogenous pain modulation is mixed, as are findings from studies using functional brain imaging to ascertain sex differences in pain-related cerebral activation. Also inconsistent are findings regarding sex differences in responses to pharmacologic and non-pharmacologic pain treatments. The article concludes with a discussion of potential biopsychosocial mechanisms that may underlie sex differences in pain, and considerations for future research are discussed.

PERSPECTIVE

This article reviews the recent literature regarding sex, gender, and pain. The growing body of evidence that has accumulated in the past 10 to 15 years continues to indicate substantial sex differences in clinical and experimental pain responses, and some evidence suggests that pain treatment responses may differ for women versus men.

Satisfaction of osteoarthritis patients with provided care is not related to the disease-specific quality of life

BACKGROUND

Osteoarthritis (OA) has a high prevalence in primary care. Patient satisfaction is an important indicator for the quality of care provided to OA patients. Little is known about satisfaction of patients with this condition in a primary care setting in Germany. The aim of the study was to assess current satisfaction of patients and reveal possible disease and quality of life related predictors.

METHODS/DESIGN

Seventy-five German GPs approached 1250 patients with OA consecutively. Sociodemographics, OA-specific quality of life (GERMAN-AIMS2-SF), co-morbidities and depression (using PHQ-9) were assessed. Patient satisfaction was measured by means of the European Task Force on Patient Evaluations of General Practice (EUROPEP) instrument. A stepwise linear regression analysis with the EUROPEP score as dependent variable controlled for the amount of GP visits was performed to assess predictors of satisfaction.

RESULTS

A total of 1021 OA patients returned the questionnaire. The adjusted R(2) of the final model was 0.270 (P < 0.001). The main predictors were the PHQ-9 score (beta = -0.372; P < 0.001), age (beta = -0.185; P < 0.001), living alone (beta = -0.209; P < 0.001) and number of co-morbidities (beta = -0.152; P < 0.001). The only disease-related factor which remained as predictor of patient satisfaction was duration of OA (beta = -0.105; P = 0.008).

DISCUSSION

The finding that depression and social factors are more important for patient satisfaction with provided care than disease-related aspects suggests that these factors need to be considered carefully in treatment. This represents a big challenge within an increasingly specialized health care system. The General Practitioner as the regular and first-choice provider of health care seems to be the most appropriate instance who can accomplish this.

The PHQ-8 as a measure of current depression in the general population

BACKGROUND

The eight-item Patient Health Questionnaire depression scale (PHQ-8) is established as a valid diagnostic and severity measure for depressive disorders in large clinical studies. Our objectives were to assess the PHQ-8 as a depression measure in a large, epidemiological population-based study, and to determine the comparability of depression as defined by the PHQ-8 diagnostic algorithm vs. a PHQ-8 cutpoint > or = 10.

METHODS

Random-digit-dialed telephone survey of 198,678 participants in the 2006 Behavioral Risk Factor Surveillance Survey (BRFSS), a population-based survey in the United States. Current depression as defined by either the DSM-IV based diagnostic algorithm (i.e., major depressive or other depressive disorder) of the PHQ-8 or a PHQ-8 score > or = 10; respondent sociodemographic characteristics; number of days of impairment in the past 30 days in multiple domains of health-related quality of life (HRQoL).

RESULTS

The prevalence of current depression was similar whether defined by the diagnostic algorithm or a PHQ-8 score > or = 10 (9.1% vs. 8.6%). Depressed patients had substantially more days of impairment across multiple domains of HRQoL, and the impairment was nearly identical in depressed groups defined by either method. Of the 17,040 respondents with a PHQ-8 score > or = 10, major depressive disorder was present in 49.7%, other depressive disorder in 23.9%, depressed mood or anhedonia in another 22.8%, and no evidence of depressive disorder or depressive symptoms in only 3.5%.

LIMITATIONS

The PHQ-8 diagnostic algorithm rather than an independent structured psychiatric interview was used as the criterion standard.

CONCLUSIONS

The PHQ-8 is a useful depression measure for population-based studies, and either its diagnostic algorithm or a cutpoint > or = 10 can be used for defining current depression.

Screening older people with musculoskeletal pain for depressive symptoms in primary care

BACKGROUND

Older patients presenting to GPs with musculoskeletal pain are at high risk of having concurrent depression.

AIM

To investigate the performance of ultra-short (1-4 items tools) screening questions used during the consultation, and through a patient questionnaire to detect depressive symptoms among older adults presenting with musculoskeletal pain to general practice.

DESIGN OF STUDY

Cross-sectional survey, linked GP consultation data.

SETTING

General practices in central Cheshire, UK.

METHOD

Consecutive patients aged > or =50 years presenting with non-inflammatory musculoskeletal pain were eligible to participate. GPs screened all patients in the consultation for the presence of depressive symptoms using two questions. All patients were sent a postal questionnaire within 1 week of consultation containing the Hospital Anxiety and Depression Scale and the written version of the depression screening questions.

RESULTS

The total number of patients included in the study was 428. In total, 35.5% of consulters had comorbid depressive symptoms, with 13.5% experiencing moderate or severe symptoms. Just over half of participants (n = 218/242; 51.4%) screened positive on self-administered screening at home compared with only 78 (20.8%) on GP-administered screening in the consultation. There was little difference between GP-administered and self-administered screening in the probability of depressive symptoms among those who screened positive with regard to exhibiting signs of having depressive symptoms.

CONCLUSION

Older patients consulting their GP with musculoskeletal pain frequently have comorbid mental ill health. Ultrashort depression screening questions administered during the consultation miss a large number of those with depressive symptoms, including six out of eight patients with severe symptoms. An improvement in the performance of screening questions in this patient group or narrowing the definition of 'high risk' from all patients aged > or =50 years presenting with musculoskeletal pain could help to improve detection.

The impact of momentary pain and fatigue on physical activity in women with osteoarthritis

OBJECTIVE

To examine the daily life patterns of both pain and fatigue symptoms and objective physical activity (using ambulatory monitoring) in women with symptomatic lower extremity osteoarthritis (OA), and to evaluate how momentary symptoms impact physical activity levels.

METHODS

Sixty women age >or=55 years (40 with knee or hip OA and 20 matched controls) participated in an observational study involving 2 laboratory visits and a 5-day home data collection period. During the home period physical activity levels were assessed continuously, and symptoms were inputted 6 times a day into an enhanced accelerometer at prespecified time points.

RESULTS

In the OA group as compared with the control group over the 5-day period, average physical activity was significantly lower (P = 0.02) and peak physical activity tended to be lower (P = 0.06). Although pain and fatigue overall were of moderate severity in this cohort, fatigue escalated throughout each day. In a hierarchical linear model, fatigue was most strongly associated with physical activity (beta = -30.1, P < 0.0001). Pain was more weakly associated with physical activity and in the direction opposite to what was hypothesized (beta = 16.9, P = 0.04).

CONCLUSION

Momentary reports of fatigue negatively predicted physical activity levels and were much more strongly related to physical activity than momentary pain. In order to help women with knee or hip OA manage symptoms and become more physically active, it may be important to emphasize fatigue management.

Factors associated with physical activity of patients with osteoarthritis of the lower limb

OBJECTIVE

In patients with osteoarthritis (OA), moderate physical activity (PA) can reduce the progress of joint damage. PA is therefore an important target of in the non-surgical treatment of OA. To know about factors associated with PA can increase the success of interventions aiming at increasing PA. The aim of the study was to determine predictors of PA in patients suffering from OA to the hip or to the knee.

METHODS

In total, 1250 outpatients from 75 general practices were consecutively approached, 1021 returned questionnaires containing sociodemographic data, and short forms of the International Physical Activity Questionnaire (IPAQ), the Arthritis Impact Measurement Scale and the Patient Health Questionnaire to assess concomitant depression. A hierarchical stepwise multiple linear regression analysis with the IPAQ continuous score as dependent variable was performed.

RESULTS

Comparison of our findings with General population suggests that the overall PA of OA patients is decreased. Main predictors of PA were physical limitation to the lower body (beta = -0.179; P = 0.001), social contacts (P = -0.134; P < 0.001), pain (beta =-0.120; P = 0.001), age (beta = -0.110; P = 0.004) and the body mass index (beta =-0.043; P < 0.001).

CONCLUSION

The findings emphasize the influence of physical as well as psychosocial factors on PA of patients with OA and should help to tailor future interventions more appropriately. Further research is needed to determine if these tailored interventions will result in better compliance and in increased PA.

Update on consultation-liaison psychiatry (psychosomatic medicine)

PURPOSE OF REVIEW

Current issues in consultation-liaison psychiatry, which is now labeled psychosomatic medicine as a formal subspecialty by the American Board of Psychiatry and Neurology, are discussed.

RECENT FINDINGS

There is continued interest in how to best manage depression and anxiety in a primary-care setting. Collaborative care that utilizes a psychiatrist within the treatment center, as well as case management by a nurse, have been reviewed and meta-analyses suggest it is an efficient and effective approach. The diagnostic issues within psychosomatic medicine are also an area of concern as the Diagnostic and Statistical Manual of Mental Disorders, 5 edition, is in the planning stages. How to improve both the reliability and validity of somatoform disorders will be a major challenge. Organ transplantation is a clinical challenge for patients, donors and healthcare providers. Issues in assessment and management continue to evolve. Ethical questions also arise due to the shortage of available organs.

SUMMARY

Psychosomatic medicine continues to manage patients in medical settings that cut across a continuum from primary-care to complex medical and surgical centers. The clinical problems containing a medical-psychiatric interface offer a clinical challenge but also an area for new knowledge and better interventions.

Case management of arthritis patients in primary care: a cluster-randomized controlled trial

OBJECTIVE

To assess whether providing information on arthritis self-management through general practitioners (GPs) increases the quality of life in patients with osteoarthritis and whether additional case management provided by practice nurses shows better results.

METHODS

We conducted a pragmatic, cluster-randomized, controlled, 3-arm trial that included 1,021 patients from 75 primary care practices in Germany. GPs were randomized to intervention group I, group II, or a control group. GPs of both intervention groups participated in 2 peer group meetings. In intervention group II, additional case management was conducted via telephone by a practice nurse. The primary outcome was change in quality of life, assessed by the German version of the Arthritis Impact Measurement Scales Short Form (AIMS2-SF). Secondary outcomes were health service utilization, prescriptions, and physical activity. Data were controlled for depression using the Patient Health Questionnaire 9 as a potential confounder.

RESULTS

Of 1,125 administered questionnaires, 1,021 were analyzed. Compared with the control group, no significant changes occurred in intervention group I with respect to the primary outcome. Performed radiographs decreased significantly (P = 0.050), whereas prescriptions of acetaminophen increased significantly (P < 0.001). In intervention group II, significant changes in the AIMS2-SF dimensions social (P < 0.001), symptom (P = 0.048), and lower body (P = 0.049) were identified. Radiographs (P = 0.031) and orthopedic referrals (P = 0.044) decreased whereas prescriptions of pain relievers increased significantly.

CONCLUSION

Improving the quality of life in patients with arthritis using arthritis self-management seems challenging. Simply providing this information through GPs is not sufficient but combining it with case management seems to be a promising approach.
