Reduction of joint pain in patients with knee osteoarthritis who have received monthly telephone calls from lay personnel and whose medical treatment regimens have remained stable

Nonsteroidal Anti-inflammatory Drugs vs Cognitive Behavioral Therapy for Arthritis Pain: A Randomized Withdrawal Trial

IMPORTANCE

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for knee osteoarthritis. However, they are associated with uncertain long-term clinical benefit and significant toxic effects.

OBJECTIVE

To evaluate whether discontinuing NSAIDs and engaging in a telephone-based cognitive behavioral therapy (CBT) program is noninferior to continuing NSAIDs for patients with knee osteoarthritis.

DESIGN, SETTING, AND PARTICIPANTS

The Stopping NSAIDs for Arthritis Pain multicenter randomized withdrawal trial was conducted for 364 patients taking NSAIDs for knee osteoarthritis pain on most days of the week for at least 3 months between September 1, 2013, and September 30, 2018. Analysis was performed on an intent-to-treat basis.

INTERVENTIONS

Participants discontinued their current NSAID and took 15 mg per day of meloxicam daily during a 2-week run-in period. Those who remained eligible were randomized in a 1:1 ratio to receive meloxicam or placebo for 4 weeks (blinded phase 1). Participants receiving meloxicam then continued this medication for 10 weeks, while those receiving placebo participated in a 10-week CBT program (unblinded phase 2).

MAIN OUTCOMES AND MEASURES

The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score at 4 weeks with the noninferiority margin set at 1. Secondary outcomes included the area under the curve of the pain score after 4 weeks as well as the WOMAC pain score, area under the curve of the pain score, WOMAC disability score, and global impression of change after treatment at 14 weeks.

RESULTS

A total of 180 participants (161 men; mean [SD] age, 58. 2 [11.8] years) were randomized to receive placebo followed by CBT, and a total of 184 participants (154 men; mean [SD] age, 58.5 [10.0] years) were randomized to receive meloxicam. After adjustment for baseline pain and study site, the estimated mean difference in WOMAC pain score between the placebo and meloxicam groups after 4 weeks was 1.4 (95% CI, 0.8-2.0; noninferiority test P = .92). At week 14, the adjusted mean difference in WOMAC pain score between the placebo (followed by CBT) and meloxicam groups was 0.8 (95% CI, 0.2-1.4; noninferiority P = .28). There was no statistically significant difference in the global impression of change (mean difference in scores, -0.2; 95% CI, -0.4 to 0.1; P = .15) or lower extremity disability (mean difference in scores, 0.9; 95% CI, -1.4 to 3.2; P = .45) between the 2 groups after 14 weeks.

CONCLUSIONS AND RELEVANCE

Among patients with knee osteoarthritis, placebo and CBT (after placebo) are inferior to meloxicam. However, the WOMAC pain score differences between the 2 groups were small, and there were no statistically significant differences in participants' global impression of change or function after 14 weeks.

Digital Self-Management Interventions for People With Osteoarthritis: Systematic Review With Meta-Analysis

BACKGROUND

Osteoarthritis (OA) is not curable, but the symptoms can be managed through self-management programs (SMPs). Owing to the growing burden of OA on the health system and the need to ensure high-quality integrated services, delivering SMPs through digital technologies could be an economic and effective community-based approach.

OBJECTIVE

This study aims to analyze the effectiveness of digital-based structured SMPs on patient outcomes in people with OA.

METHODS

A total of 7 web-based and 3 gray literature databases were searched for randomized controlled trials assessing digital-based structured SMPs on self-reported outcomes including pain, physical function, disability, and health-related quality of life (QoL) in people with OA. Two reviewers independently screened the search results and reference lists of the identified papers and related reviews. Data on the intervention components and delivery and behavioral change techniques used were extracted. A meta-analysis, risk of bias sensitivity analysis, and subgroup analysis were performed where appropriate. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the quality of evidence.

RESULTS

A total of 8 studies were included in this review involving 2687 patients with knee (n=2); knee, hip, or both (n=5); and unspecified joint (n=1) OA. SMPs were delivered via telephone plus audio and video, internet, or mobile apps. Studies reported that digital-based structured SMPs compared with the treatment as usual control group (n=7) resulted in a significant, homogeneous, medium reduction in pain and improvement in physical function (standardized mean difference [SMD] -0.28, 95% CI -0.38 to -0.18 and SMD -0.26, 95% CI -0.35 to -0.16, respectively) at posttreatment. The digital-based structured SMP effect on pain and function reduced slightly at the 12-month follow-up but remained to be medium and significant. The posttreatment effect of digital-based structured SMPs was small and significant for disability, but nonsignificant for QoL (SMD -0.10, 95% CI -0.17 to 0.03 and SMD -0.17, 95% CI -0.47 to 0.14, respectively; each reported in 1 study only). The 12-month follow-up effect of the intervention was very small for disability and QoL. The quality of evidence was rated as moderate for pain and physical function and low and very low for disability and QoL, respectively, using the GRADE approach.

CONCLUSIONS

Digital-based structured SMPs may result in improvement in pain and physical function that is largely sustained at the 12-month follow-up in people with knee and hip OA. The effects on disability and QoL are smaller and less clear. The quality of evidence is moderate to low, and further research is required to confirm the findings of the review and assess the effects of digital-based structured SMPs on other health-related outcomes.

Home-based management of knee osteoarthritis during COVID-19 pandemic: literature review and evidence-based recommendations

Purpose

To provide evidence-based recommendations for patients with severe knee osteoarthritis (OA), who had their knee surgery postponed due to the COVID-19 pandemic.

Methods

PubMed/Medline, Scopus and Cochrane Central databases were systematically reviewed for studies reporting outcomes of home-based treatments for knee OA. Due to between-study differences in treatment strategy and reporting methods the results were not pooled and findings of the current review were presented in a narrative manner.

Results

The comprehensive literature search yielded 33 eligible studies that were included in this review. Management is performed at home and consists of exercise, proper nutrition, physical therapy and use of corrective and assistive orthotics. Virtual education on self-management strategies should be part of coping with knee OA. Initiating an exercise programme involving gymnastics, stretching, home cycling and muscle strengthening is highly recommended. Obese patients are encouraged to set weight loss goals and adopt a healthy diet. Potential benefits but weak evidence has been shown for the use of knee braces, sleeves, foot orthotics or cushioned footwear. Walking aids may be prescribed, when considered necessary, along with the provision of instructions for their use.

Conclusion

When bridging the time to rescheduled surgery, it is essential to use appropriate home-based tools for the management of knee OA if pain is to be reduced and need for analgesics or opioid use is to be diminished while maintaining or even improving the functioning and avoiding further limitation of range of motion and subsequent muscular atrophies. Finally, none of these treatments may completely substitute for the life-changing effect of a total knee arthroplasty in patients with severe knee OA. Hence, the subsequent goal is to gradually and safely reinstate elective surgery.

Comparative Impact of Nonpharmacological Interventions on Pain of Knee Osteoarthritis Patients Reporting at a Tertiary Care Institution: A Randomized Controlled Trial

Context:

Nonpharmacological interventions (NPIs) have been advocated for knee osteoarthritis (KOA). There are many gaps in the evidence to their efficacy in India.

Aims:

The study aims to compare the impact of two packages of NPIs on various outcome variables of KOA patients.

Settings and Design:

This was a randomized controlled trial in a tertiary care hospital.

Subjects and Methods:

A study population (n = 123) of KOA patients aged 40–65 years. Stratified block randomization was done for mild or moderate KOA into two groups. Group “A” patients received a package of NPIs including a set of supervised exercise sessions, kinesthesia, balance, and agility (KBA), meditation, weight reduction advice, and weekly telephonic reminders. Group “B” patients received the same package except for KBA & meditation. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) and performance-based measures were measured.

Analysis:

t-test and repeat measures ANOVA were undertaken.

Results:

A significant intragroup reduction in WOMAC score was seen from baseline in Group A (P = 0.00, mean difference: −9.7) as well as in Group B (P = 0.00, −12.9). There was also significant reduction inVAS scores at the end of intervention in Group A and Group B as compared from baseline (−3.62, −3.8, P = 0.00). No intergroup difference was observed in either of the scores. VAS score reduction to 0 at different stages of intervention was noticed in 46% (n = 57) cases. There was a significant intergroup difference for 50-Foot Walk Test (P = 0.055, F = 3.28) at 12 months.

Conclusion:

Both packages of NPIs were effective in providing relief in symptoms. No specific benefit of KBA or meditation was seen except for 50FWT.

Discontinuing a non-steroidal anti-inflammatory drug (NSAID) in patients with knee osteoarthritis: Design and protocol of a placebo-controlled, noninferiority, randomized withdrawal trial

BACKGROUND

Knee osteoarthritis (OA) is the most common cause of knee pain in older adults. Despite the limited data supporting their use, non-steroidal anti-inflammatory drugs (NSAID) are among the most commonly prescribed medications for knee OA. The use of NSAIDs for knee pain warrants careful examination because of toxicity associated with this class of medications.

METHODS

We describe the design of a placebo-controlled, noninferiority, randomized withdrawal trial to examine discontinuation of an NSAID in patients with painful knee OA. Participants will be veterans enrolled in the VA Healthcare System with knee OA pain despite NSAID use and/or relatively higher risk of NSAID toxicity. After a two-week run-in period where eligible subjects will replace their current NSAID with the study NSAID (meloxicam), those remaining eligible (target N=544) will be randomized to receive four weeks of either placebo or continued meloxicam. The primary outcome is knee pain (Western Ontario and McMaster Universities Osteoarthritis Index pain subscale, range 0-20) at four weeks post-randomization. The primary hypothesis is that placebo will be noninferior to (that is, not much worse than) meloxicam within a noninferiority margin of 1. Secondary outcomes include lower extremity disability, global impression of change, adherence to study medication and use of co-therapies.

DISCUSSION

This study is the first clinical trial to date examining the effects of withdrawing an NSAID for OA knee pain. If successful, this trial will provide evidence against the continued use of NSAIDs in patients with OA knee pain.

Peer support groups in multiple sclerosis: current effectiveness and future directions

Peer support programs have become a common method of providing support for patients with chronic illness. Utilizing peers as resources has been proposed as an effective means for coping with a stressful life experience and for gaining support from others who share a common factor, although data are somewhat mixed on the efficacy of peer support. The aim of the present study was to evaluate the effectiveness of eight weeks of a standard form of peer support in improving quality of life and reducing depressive symptoms in 44 patients with multiple sclerosis (MS). O ne person from each of six groups participated in a training course in order to learn basic principles of peer support. Eight weekly sessions were held and patients completed self-administered questionnaires pre- and post- treatment assessing quality of life and depression. Results showed that support groups do not provide consistent improvement in quality of life or depression in patients with MS and suggest that patients who have better mental health functioning could be at risk for deterioration in support groups.

A preliminary report on a skills-based telephone-administered peer support programme for patients with multiple sclerosis

Objective: Peer-support interventions have shown no statistically significant or clinically meaningful effect on quality of life (QOL) or depressive symptoms for multiple sclerosis (MS) patients. Peer-support interventions for MS generally provide support but no skills training. The aim of this study was to evaluate a brief telephone-administered skills-training model of peer-support for patients with MS. Methods: Sixteen patients with MS showing signs of moderate distress received eight sessions of telephone-administered peer support (TAPS). TAPS is a manualized programme administered by peer-support counsellors diagnosed with MS. Using a workbook, peer-support counsellors teach skills to manage distress and MS symptoms. Subjective depression was assessed using the Center for Epidemiological Studies Depression Scale while objective depression was rated using the Hamilton Rating Scale for Depression. QOL was measured preand post-treatment using the SF-36. Results: The participants showed significant improvements on both the CESD (p=0.04) and the HRSD (p=0.01). Overall QOL improved significantly (p=0.045), however this was not reflected in either the Physical Health composite score or the Mental Health Composite Scale (p-0.17). Conclusions: These findings suggest that TAPS may prove to be an efficacious peer-support model for patients with MS.

An evaluation of exercise regimes for patients with osteoarthritis of the knee: a single-blind randomized controlled trial

Osteoarthritis (OA) of the knee is a major public health problem in the United Kingdom and various forms of physiotherapy are used in the treatment of this condition despite the lack of studies evaluating its efficacy. The purpose of this study was to compare the efficacy of two different forms of physiotherapy exercise management with a control group.

Twenty-seven patients with OA knee were recruited from routine orthopaedic clinics and were on the waiting-list for physiotherapy. Patients were randomly allocated to three groups. Group 1 ( n = 9) consisted of a control group; Group 2 ( n = 8) consisted of supervised sessions of exercises; Group 3 ( n = 10) consisted of an advice and instruction session plus a functional home exercise regime.

Parameters measured were: pain; range of motion; quadriceps strength; knee joint swelling; exercise tolerance.

Results were analysed using a Kruskal-Wallis analysis of variance and a Mann-Whitney U-test with the significance level set at p <0.05. The results showed no significant difference ( p >0.05) between any of the outcome measures of the three groups. This study concludes that patients with OA knee can be helped most economically by one session of advice and a functional home exercise regime. This can be done in a group setting under supervision of one physiotherapist.

Physical Therapists, Telephone Coaches, and Patients With Knee Osteoarthritis: Qualitative Study About Working Together to Promote Exercise Adherence

BACKGROUND

Integrated models of care are recommended for people with knee osteoarthritis (OA). Exercise is integral to management, yet exercise adherence is problematic. Telephone-based health coaching is an attractive adjunct to physical therapist-prescribed exercise that may improve adherence. Little is known about the perceptions and interpretations of physical therapists, telephone coaches, and patients engaged in this model of care.

OBJECTIVES

The purpose of this study was to explore how stakeholders (physical therapists, telephone coaches, and patients) experienced, and made sense of, being involved in an integrated program of physical therapist-supervised exercise and telephone coaching for people with knee OA.

DESIGN

A cross-sectional qualitative design drawing from symbolic interactionism was used.

METHODS

Semistructured interviews with 10 physical therapists, 4 telephone coaches, and 6 patients with painful knee OA. Interviews were audiorecorded, transcribed, and analyzed using thematic analysis informed by grounded theory.

RESULTS

Four themes emerged: (1) genuine interest and collaboration, (2) information and accountability, (3) program structure, and (4) roles and communication in teamwork. Patients reported they appreciated personalized, genuine interest from therapists and coaches and were aware of their complementary roles. A collaborative approach, with defined roles and communication strategies, was identified as important for effectiveness. All participants highlighted the importance of sharing information, monitoring, and being accountable to others. Coaches found the lack of face-to-face contact with patients hampered relationship building. Therapists and coaches referred to the importance of teamwork in delivering the intervention.

LIMITATIONS

The small number of physical therapists and telephone coaches who delivered the intervention may have been biased toward favorable experiences with the intervention and may not be representative of their respective professions.

CONCLUSIONS

Integrated physical therapy and telephone coaching was perceived as beneficial by most stakeholders. Programs should be structured but have some flexibility to give therapists and coaches some freedom to adjust treatment to individual patient needs as required. Opportunities for visual communication between telephone coaches and patients could facilitate relationship building.

The effect of muscle facilitation using kinesio taping on walking and balance of stroke patients

[Purpose] The aim of this study was to evaluate the changes in function and balance after Kinesio Taping application in stroke patients. [Subjects and Methods] Thirty subjects were randomly divided into an experimental group and control group. The experimental group was applied taping before therapeutic exercise, and the control group received only therapeutic exercise. Functional gait was measured using the straight line walking test, and dynamic balance ability was measured using the Berg Balance Scale. Walking velocity was measured with the 10 m walking test. [Results] There were statistically significant differences between the results of the straight line walking and 10 m walking tests in the pre-post analysis for the experimental group. There were a statistically significant difference in the Berg Balance Scale and 10 m walking test between the two groups. [Conclusion] Application of taping to the paralyzed parts of a stroke patient has a positive effect on improvement of typical asymmetric gait and walking speed.

Addition of telephone coaching to a physiotherapist-delivered physical activity program in people with knee osteoarthritis: a randomised controlled trial protocol

Background

Knee osteoarthritis (OA) is one of the most common and costly chronic musculoskeletal conditions world-wide and is associated with substantial pain and disability. Many people with knee OA also experience co-morbidities that further add to the OA burden. Uptake of and adherence to physical activity recommendations is suboptimal in this patient population, leading to poorer OA outcomes and greater impact of associated co-morbidities. This pragmatic randomised controlled trial will investigate the clinical- and cost-effectiveness of adding telephone coaching to a physiotherapist-delivered physical activity intervention for people with knee OA.

Methods/Design

168 people with clinically diagnosed knee OA will be recruited from the community in metropolitan and regional areas and randomly allocated to physiotherapy only, or physiotherapy plus nurse-delivered telephone coaching. Physiotherapy involves five treatment sessions over 6 months, incorporating a home exercise program of 4–6 exercises (targeting knee extensor and hip abductor strength) and advice to increase daily physical activity. Telephone coaching comprises 6–12 telephone calls over 6 months by health practitioners trained in applying the Health Change Australia (HCA) Model of Health Change to provide behaviour change support. The telephone coaching intervention aims to maximise adherence to the physiotherapy program, as well as facilitate increased levels of participation in general physical activity. The primary outcomes are pain measured by an 11-point numeric rating scale and self-reported physical function measured by the Western Ontario and McMaster Universities Osteoarthritis Index subscale after 6 months. Secondary outcomes include physical activity levels, quality-of-life, and potential moderators and mediators of outcomes including self-efficacy, pain coping and depression. Relative cost-effectiveness will be determined from health service usage and outcome data. Follow-up assessments will also occur at 12 and 18 months.

Discussion

The findings will help determine whether the addition of telephone coaching sessions can improve sustainability of outcomes from a physiotherapist-delivered physical activity intervention in people with knee OA.

Mechanisms underpinning effective peer support: a qualitative analysis of interactions between expert peers and patients newly-diagnosed with bipolar disorder

BACKGROUND

The increasing burden on mental health services has led to the growing use of peer support in psychological interventions. Four theoretical mechanisms have been proposed to underpin effective peer support: advice grounded in experiential knowledge, social support, social comparison and the helper therapy principle. However, there has been a lack of studies examining whether these mechanisms are also evident in clinical populations in which interpersonal dysfunction is common, such as bipolar disorder.

METHOD

This qualitative study, conducted alongside a randomized controlled trial, examined whether the four mechanisms proposed to underpin effective peer support were expressed in the email exchange between 44 individuals newly-diagnosed with bipolar disorder and their Informed Supporters (n = 4), over the course of a supported online psychoeducation program for bipolar disorder. A total of 104 text segments were extracted and coded. The data were complemented by face-to-face interviews with three of the four Informed Supporters who participated in the study.

RESULTS

Qualitative analyses of the email interchange and interview transcripts revealed rich examples of all four mechanisms. The data illustrated how the involvement of Informed Supporters resulted in numerous benefits for the newly-diagnosed individuals, including the provision of practical strategies for illness management as well as emotional support throughout the intervention. The Informed Supporters encouraged the development of positive relationships with mental health services, and acted as role models for treatment adherence. The Informed Supporters themselves reported gaining a number of benefits from helping, including a greater sense of connectedness with the mental health system, as well as a broader knowledge of illness management strategies.

CONCLUSIONS

Examples of the mechanisms underpinning effective peer support were found in the sample of emails from individuals with newly-diagnosed bipolar disorder and their Informed Supporters. Experiential knowledge, social support, social comparison and helper therapy were apparent, even within a clinical population for whom relationship difficulties are common. Trial registration number ACTRN12608000411347.

Telephone Support Groups for Seniors with Disabilities

On constate une augmentation de la population des aîné(e)s souffrant d'invalidité, qui sont mal soutenus et qui sont seuls. Bien qu'un groupe de soutien puisse être formé par les pairs, les aîné(e)s dont les capacités physiques sont limitées y ont bien souvent difficilement accès. Ce projet visait à établir un groupe de soutien téléphonique pour les aîné(e)s souffrant d'invalidité et à en vérifier les résultats. L'étude se composait de six questions. On a formé quatre groupes de soutien téléphonique constitué de cinq à six membres chacun (n = 23) ayant à leur tête un spécialiste et un aîné(e). Les groupes se rencontraient une fois la semaine pendant 12 semaines. Une analyse qualitative de la transcription des appels et des interventions subséquentes des participants et des chefs a révélé une diminution des besoins de soutien, moins de solitude et une meilleure réaction face aux circonstances. La sélection, la formation et l'appui des pairs et des spécialistes ainsi qu'un bonne orientation des échanges ont été des facteurs importants du succès des groupes.

Non-pharmacological care for patients with generalized osteoarthritis: design of a randomized clinical trial

Background

Non-pharmacological treatment (NPT) is a useful treatment option in the management of hip or knee osteoarthritis. To our knowledge however, no studies have investigated the effect of NPT in patients with generalized osteoarthritis (GOA). The primary aim of this study is to compare the effectiveness of two currently existing health care programs with different intensity and mode of delivery on daily functioning in patients with GOA. The secondary objective is to compare the cost-effectiveness of both interventions.

Methods/Design

In this randomized, single blind, clinical trial with active controls, we aim to include 170 patients with GOA. The experimental intervention consist of six self-management group sessions provided by a multi-disciplinary team (occupational therapist, physiotherapist, dietician and specialized nurse). The active control group consists of two group sessions and four sessions by telephone, provided by a specialized nurse and physiotherapist. Both therapies last six weeks. Main study outcome is daily functioning during the first year after the treatment, assessed on the Health Assessment Questionnaire. Secondary outcomes are health related quality of life, specific complaints, fatigue, and costs. Illness cognitions, global perceived effect and self-efficacy, will also be assessed for a responder analysis. Outcome assessments are performed directly after the intervention, after 26 weeks and after 52 weeks.

Discussion

This article describes the design of a randomized, single blind, clinical trial with a one year follow up to compare the costs and effectiveness of two non-pharmacological interventions with different modes of delivery for patients with GOA.

Guidelines for the use of nonsurgical interventions in osteoarthritis management

Osteoarthritis (OA) is a major cause of disability in the population and interventions are necessary to optimize function in patients with this disease. The recommended OA therapy consists of a basic set of interventions to maintain function as far as possible, including information, weight loss (in the case of obesity) and exercises. To ensure compliance with such programs and to relieve pain, a stepwise increasing analgesia may be added, beginning with paracetamol and supplemented by second-line analgesics, including opioids for more significant pain situations. The role of nonsteroidal anti-inflammatory drugs, is suggested to be that of treating flares of disease activity characterized by inflammation; they should not be used routinely. Alternative medications are widely used by patients and may have some role in pain relief, although the potency of such compounds is generally somewhat low.

Different models to mobilize peer support to improve diabetes self-management and clinical outcomes: evidence, logistics, evaluation considerations and needs for future research

Much of diabetes care needs to be carried out by patients between office visits with their health care providers. Yet, many patients face difficulties carrying out these tasks. In addition, many adults with diabetes cannot count on effective support from their families and friends to help them with their self-management. Peer support programmes are a promising approach to enhance social and emotional support, assist patients in daily management and living with diabetes and promote linkages to clinical care. This background paper provides a brief overview of different approaches to mobilize peer support for diabetes self-management support, discusses evidence to date on the effectiveness of each of these models, highlights logistical and evaluation issues for each model and concludes with a discussion of directions for future research in this area.

Peer support telephone calls for improving health

BACKGROUND

Peer support telephone calls have been used for a wide range of health-related concerns. However, little is known about their effects.

OBJECTIVES

To assess the effects of peer support telephone calls in terms of physical (e.g. blood pressure), psychological (e.g. depressive symptoms), and behavioural health outcomes (e.g. uptake of mammography) and other outcomes.

SEARCH STRATEGY

We searched: The Cochrane Library databases (CENTRAL, DARE, CDSR) (issue 4 2007); MEDLINE (OVID) (January 1966 to December 2007); EMBASE (OVID) (January 1985 to December 2007); CINAHL (Athens) (January 1966 to December 2007), trials registers and reference lists of articles, with no language restrictions.

SELECTION CRITERIA

Randomised controlled trials of peer support interventions delivered by telephone call.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data. We present results narratively and in tabular format. Meta-analysis was not possible due to heterogeneity between studies.

MAIN RESULTS

We included seven studies involving 2492 participants.Peer support telephone calls were associated with an increase in mammography screening, with 49% of women in the intervention group and 34% of women in the control group receiving a mammogram since the start of the intervention (P </ = 0.001). In another study, peer telephone support calls were found to maintain mammography screening uptake for baseline adherent women (P = 0.029).Peer support telephone calls for post myocardial infarction patients were associated at six months with a change in diet in the intervention and usual care groups of 54% and 44% respectively (P = 0.03). In another study for post myocardial infarction patients there were no significant differences between groups for self-efficacy, health status and mental health outcomes.Peer support telephone calls were associated with greater continuation of breastfeeding in mothers at 3 months post partum (P = 0.01).Peer support telephone calls were associated with reduced depressive symptoms in mothers with postnatal depression (Edinburgh Postnatal Depression Scale (EPDS) > 12). The peer support intervention significantly decreased depressive symptomatology at the 4-week assessment (odds ratio (OR) 6.23 (95% confidence interval (CI) 1.15 to 33.77; P = 0.02)) and 8-week assessment (OR 6.23 (95% CI 1.40 to 27.84; P = 0.01). One study investigated the use of peer support for patients with poorly controlled diabetes. There were no significant differences between groups for self-efficacy, HbA1C, cholesterol level and body mass index.

AUTHORS' CONCLUSIONS

Whilst this review provides some evidence that peer support telephone calls can be effective for certain health-related concerns, few of the studies were of high quality and so results should be interpreted cautiously. There were many methodological limitations thus limiting the generalisability of findings. Overall, there is a need for further well designed randomised controlled studies to clarify the cost and clinical effectiveness of peer support telephone calls for improvement in health and health-related behaviour.

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.

OARSI recommendations for the management of hip and knee osteoarthritis, Part II: OARSI evidence-based, expert consensus guidelines

PURPOSE

To develop concise, patient-focussed, up to date, evidence-based, expert consensus recommendations for the management of hip and knee osteoarthritis (OA), which are adaptable and designed to assist physicians and allied health care professionals in general and specialist practise throughout the world.

METHODS

Sixteen experts from four medical disciplines (primary care, rheumatology, orthopaedics and evidence-based medicine), two continents and six countries (USA, UK, France, Netherlands, Sweden and Canada) formed the guidelines development team. A systematic review of existing guidelines for the management of hip and knee OA published between 1945 and January 2006 was undertaken using the validated appraisal of guidelines research and evaluation (AGREE) instrument. A core set of management modalities was generated based on the agreement between guidelines. Evidence before 2002 was based on a systematic review conducted by European League Against Rheumatism and evidence after 2002 was updated using MEDLINE, EMBASE, CINAHL, AMED, the Cochrane Library and HTA reports. The quality of evidence was evaluated, and where possible, effect size (ES), number needed to treat, relative risk or odds ratio and cost per quality-adjusted life years gained were estimated. Consensus recommendations were produced following a Delphi exercise and the strength of recommendation (SOR) for propositions relating to each modality was determined using a visual analogue scale.

RESULTS

Twenty-three treatment guidelines for the management of hip and knee OA were identified from the literature search, including six opinion-based, five evidence-based and 12 based on both expert opinion and research evidence. Twenty out of 51 treatment modalities addressed by these guidelines were universally recommended. ES for pain relief varied from treatment to treatment. Overall there was no statistically significant difference between non-pharmacological therapies [0.25, 95% confidence interval (CI) 0.16, 0.34] and pharmacological therapies (ES=0.39, 95% CI 0.31, 0.47). Following feedback from Osteoarthritis Research International members on the draft guidelines and six Delphi rounds consensus was reached on 25 carefully worded recommendations. Optimal management of patients with OA hip or knee requires a combination of non-pharmacological and pharmacological modalities of therapy. Recommendations cover the use of 12 non-pharmacological modalities: education and self-management, regular telephone contact, referral to a physical therapist, aerobic, muscle strengthening and water-based exercises, weight reduction, walking aids, knee braces, footwear and insoles, thermal modalities, transcutaneous electrical nerve stimulation and acupuncture. Eight recommendations cover pharmacological modalities of treatment including acetaminophen, cyclooxygenase-2 (COX-2) non-selective and selective oral non-steroidal anti-inflammatory drugs (NSAIDs), topical NSAIDs and capsaicin, intra-articular injections of corticosteroids and hyaluronates, glucosamine and/or chondroitin sulphate for symptom relief; glucosamine sulphate, chondroitin sulphate and diacerein for possible structure-modifying effects and the use of opioid analgesics for the treatment of refractory pain. There are recommendations covering five surgical modalities: total joint replacements, unicompartmental knee replacement, osteotomy and joint preserving surgical procedures; joint lavage and arthroscopic debridement in knee OA, and joint fusion as a salvage procedure when joint replacement had failed. Strengths of recommendation and 95% CIs are provided.

CONCLUSION

Twenty-five carefully worded recommendations have been generated based on a critical appraisal of existing guidelines, a systematic review of research evidence and the consensus opinions of an international, multidisciplinary group of experts. The recommendations may be adapted for use in different countries or regions according to the availability of treatment modalities and SOR for each modality of therapy. These recommendations will be revised regularly following systematic review of new research evidence as this becomes available.

Arthritis pain

Arthritic pain is a common and disabling problem for many older adults. There is widespread evidence that despite its prevalance and debilitating effects on the physical, emotional and cognitive status of older adults, arthritic pain remains under-treated in those age 65 and older. This condition significantly and negatively impacts older adults' quality of life and is a critical problem that requires the attention of gerontological social work. This chapter provides a brief summary of arthritic pain in older adults. It also discusses the treatment efficacy of cognitive-behavioral therapy and psycho-educational programs for older adults with this type of pain.

"I am not alone": the feasibility and acceptability of interactive voice response-facilitated telephone peer support among older adults with heart failure

Patient self-management is a critical determinant of heart failure (HF) outcomes, yet patients with HF are often frail and socially isolated, factors that may limit their ability to manage self-care and access clinic-based services. Mobilizing peer support among HF patients is a promising strategy to improve self-management support. In this pilot, the authors evaluated the feasibility and acceptability of an interactive voice response (IVR)-based platform to facilitate telephone peer support among older adults with HF. Participants completed a baseline survey, were offered a 3-hour training session in peer communication skills, and were paired with another patient who had HF. Participants were asked to contact their partner weekly using a toll-free IVR phone system that protected their anonymity and provided automated reminders if contacts were not made. Times and duration of participants' telephone contacts were monitored and recorded. After the 7-week intervention, participants completed surveys and brief face-to-face interviews. The authors found high levels of use and satisfaction and improvements in depressive symptoms among the 20 pilot study participants. An IVR peer-support intervention is feasible, is acceptable to patients, and may have positive effects on patients' HF social support and health outcomes, in conjunction with structured health system support, that warrant more rigorous evaluation in a randomized trial.

Osteoarthritis and functional disability: results of a cross sectional study among primary care patients in Germany

BACKGROUND

The aim of the study was to determine factors associated with functional disability in patients with OA.

METHODS

1250 questionnaires were distributed to OA outpatients from 75 general practices; 1021 (81.6%) were returned. Questionnaires included sociodemographic data, the short form of the Arthritis Impact Measurement Scale (AIMS2-SF), and the Patient Health Questionnaire (PHQ-9) to assess concomitant depression. A hierarchical stepwise multiple regression analysis with the AIMS2-SF dimension "lower body" as dependent was performed.

RESULTS

Main factors associated with functional disability were depression symptoms, as reflected in a high score of the PHQ-9 (beta = 0.446; p < 0.0009), pain as reflected in the AIMS2-SF symptom scale (beta = 0.412; p = 0.001), and few social contacts (beta = 0.201; p < 0.042). A high body mass index was associated with lower functional ability (beta = 0.332; p = 0.005) whereas a higher educational level (beta = -0.279; p = 0.029) predicted less impairment. Increased age was a weak predictor (beta = 0.178; p = 0.001) of disability. With a p of 0.062 the radiological severity according to the grading of Kellgren and Lawrence slightly surpassed the required significance level for remaining in the final regression model.

CONCLUSION

The results emphasize that psychological as well as physical factors need to be addressed similarly to improve functional ability of patients suffering from OA. More research with multifaceted and tailored interventions is needed to determine how these factors can be targeted appropriately.

The relationship between personal traits and job satisfaction among Taiwanese community health volunteers

AIM

The purpose of the study was to understand the relationship between job satisfaction and personal traits in health volunteers in one community in Taiwan.

BACKGROUND

Among different kinds of community resources, the human resource is most essential for the process of developing healthy communities and cities. However, it is not easy to keep voluntary workers as part of health programmes even though they have been trained. Previous research has shown that to increase the job satisfaction of such a person, the volunteer needs to improve effectively his/her need to achieve. The need to achieve is an important part of a person's personal traits.

METHODS

A cross-sectional survey design was used to interview 317 health volunteers in various community health centres in I-lan county, northern Taiwan. The research instruments of this study included the 'locus of control orientation scale' for personality measurement, the 'achievement orientation scale' and the 'job satisfaction scale'.

RESULTS

Most of the sample volunteers were female with an average age of 49.55 years; the majority was married and living with their spouses. In terms of the volunteers' personal traits, most of them are internal control orientation. The job satisfaction of the volunteers who took part in this research was extremely high. Significant variables correlating with job satisfaction in this study were gender, educational level, religious preference, participation in training, working to promote community health, the willingness to work, the frequency of participating in job training, and cooperation with other volunteer partners. The explainable variance for the prediction of job satisfaction from a combination of achievement orientation and the frequency of collaboration with other people was 9.1%.

RELEVANCE TO CLINICAL PRACTICE

The results suggest that there is a need to strengthen cooperative relationships among volunteer by initiating well-planned volunteer training programmes and growth groups with the aim of enhancing their interpersonal relationships.

The management of osteoarthritis in the obese patient: practical considerations and guidelines for therapy

Obesity and osteoarthritis (OA) co-exist in an increasing part of the population. The two diseases intertwine in several ways. The evolution in the population shows a tendency towards deterioration of both by increasing general age and weight. The two diseases share pathogenetic features and the development of one disease increases the risk of the other and may be the onset of a vicious circle. There is a link between treatments of these two diseases as well. There is now solid (gold) evidence that by treating effectively the obesity of patients with co-occurring OA, the functional status is dramatically ameliorated; the short-term results are equal to that of a joint replacement. The long-term efficacy of a weight loss remains to be shown. OA is definitely one of many diseases in which obesity must be taken seriously into account when planning a correct treatment of patients. The regimens used in the controlled studies of such patients are reviewed and it may be concluded that practical aspects of the dietary intervention in obese patients with OA are not different from general recommendations.

Telephone follow-up, initiated by a hospital-based health professional, for postdischarge problems in patients discharged from hospital to home

BACKGROUND

It is known that many patients encounter a variety of problems in the first weeks after they have been discharged from hospital to home. In recent years many projects have addressed discharge planning, with the aim of reducing problems after discharge. Telephone follow-up (TFU) is seen as a good means of exchanging information, providing health education and advice, managing symptoms, recognising complications early, giving reassurance and providing quality aftercare service. Some research has shown that telephone follow-up is feasible, and that patients appreciate such calls. However, at present it is not clear whether TFU is also effective in reducing postdischarge problems.

OBJECTIVES

To assess the effects of follow-up telephone calls in the first month post discharge, initiated by hospital-based health professionals, to patients discharged from hospital to home.

SEARCH STRATEGY

We searched the following databases from their start date to July 2003, without limits as to date of publication or language: the Cochrane Consumers and Communication Review Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), PubMed, EMBASE (OVID), BiomedCentral, CINAHL, ERIC (OVID), INVERT (Dutch nursing literature index), LILACS, Picarta (Dutch library system), PsycINFO/PsycLIT (OVID), the Combined Social and Science Citation Index Expanded (SCI-E), SOCIOFILE. We searched for ongoing research in the following databases: National Research Register (http://www.update-software.com/nrr/); Controlled Clinical Trials (http://www.controlled-trials.com/); and Clinical Trials (http://clinicaltrials.gov/). We searched the reference lists of included studies and contacted researchers active in this area.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of TFU initiated by a hospital-based health professional, for patients discharged home from an acute hospital setting. The intervention was delivered within the first month after discharge; outcomes were measured within 3 months after discharge, and either the TFU was the only intervention, or its effect could be analysed separately.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and for methodological quality. The methodological quality of included studies was assessed using the criteria from the Cochrane Effective Practice and Organisation of Care Review Group. The data-extraction form was based on the template developed by the Cochrane Consumers and Communication Review Group. Data was extracted by one review author and checked by a second author. For as far it was considered that there was enough clinical homogeneity with regard to patient groups and measured outcomes, statistical pooling was planned using a random effects model and standardised mean differences for continuous scales and relative risks for dichotomous data, and tests for statistical heterogeneity were performed.

MAIN RESULTS

We included 33 studies involving 5110 patients. Predominantly, the studies were of low methodological quality. TFU has been applied in many patient groups. There is a large variety in the ways the TFU was performed (the health professionals who undertook the TFU, frequency, structure, duration, etc.). Many different outcomes have been measured, but only a few were measured across more than one study. Effects are not constant across studies, nor within patient groups. Due to methodological and clinical diversity, quantitative pooling could only be performed for a few outcomes. Of the eight meta-analyses in this review, five showed considerable statistical heterogeneity. Overall, there was inconclusive evidence about the effects of TFU.

AUTHORS' CONCLUSIONS

The low methodological quality of the included studies means that results must be considered with caution. No adverse effects were reported. Nevertheless, although some studies find that the intervention had favourable effects for some outcomes, overall the studies show clinically-equivalent results between TFU and control groups. In summary, we cannot conclude that TFU is an effective intervention.

How can the practice nurse be more involved in the care of the chronically ill? The perspectives of GPs, patients and practice nurses

BACKGROUND

A well established "midlevel" of patient care, such as nurse practitioners and/or physician assistants, exits in many countries like the US, Canada, and Australia. In Germany, however there is only one kind of profession assisting the physician in practices, the practice nurse. Little is known about the present involvement of practice nurses in patients' care in Germany and about the attitudes of GPs, assistants and patients concerning an increased involvement. The aim of our study was to get qualitative information on the extent to which practice nurses are currently involved in the treatment of patients and about possibilities of increased involvement as well as on barriers of increased involvement.

METHODS

We performed qualitative, semi-structured interviews with 20 GPs, 20 practice nurses and 20 patients in the Heidelberg area. The interviews were digitally recorded, transcribed and content-analysed with ATLAS.ti.

RESULTS

Practice nurses are only marginally involved in the treatment of patients. GPs as well as patients were very sceptical about increased involvement in care. Patients were sceptical about nurses' professional background and feared a worsening of the patient doctor relationship. GPs also complained about the nurses' deficient education concerning medical knowledge. They feared a lack of time as well as a missing reimbursement for the efforts of an increased involvement. Practice nurses were mostly willing to be more involved, regarding it as an appreciation of their role. Important barriers were lack of time, overload with administrative work, and a lack of professional knowledge.

CONCLUSION

Practice nurses were only little involved in patient care. GPs were more sceptical than patients regarding an increased involvement. One possible area, accepted by all interviewed groups, was patient education as for instance dietary counselling. New treatment approaches as the chronic care model will require a team approach which currently only marginally exists in the German health care system. Better medical education of practice nurses is indispensable, but GPs also have to accept that they cannot fulfil the requirement of future care alone.

Short- and long-term efficacy of brief cognitive-behavioral therapy for patients with chronic temporomandibular disorder pain: a randomized, controlled trial

We evaluated the short- and long-term efficacy of a brief cognitive-behavioral therapy (CBT) for chronic temporomandibular disorder (TMD) pain in a randomized controlled trial. TMD clinic patients were assigned randomly to four sessions of either CBT (n=79) or an education/attention control condition (n=79). Participants completed outcome (pain, activity interference, jaw function, and depression) and process (pain beliefs, catastrophizing, and coping) measures before randomization, and 3 (post-treatment), 6, and 12 months later. As compared with the control group, the CBT group showed significantly greater improvement across the follow-ups on each outcome, belief, and catastrophizing measure (intent-to-treat analyses). The CBT group also showed a greater increase in use of relaxation techniques to cope with pain, but not in use of other coping strategies assessed. On the primary outcome measure, activity interference, the proportion of patients who reported no interference at 12 months was nearly three times higher in the CBT group (35%) than in the control group (13%) (P=0.004). In addition, more CBT than control group patients had clinically meaningful improvement in pain intensity (50% versus 29% showed > or =50% decrease, P=0.01), masticatory jaw function (P<0.001), and depression (P=0.016) at 12 months (intent-to-treat analyses). The two groups improved equivalently on a measure of TMD knowledge. A brief CBT intervention improves one-year clinical outcomes of TMD clinic patients and these effects appear to result from specific ingredients of the CBT.

"I help you, and you help me": facilitated telephone peer support among patients with diabetes

PURPOSE

The feasibility and acceptability of using an Interactive Voice Response (IVR)-based platform to facilitate peer support among older adults with diabetes was evaluated.

METHODS

Diabetes patients with poor glycemic control receiving care at a Veterans' Affairs medical center completed a baseline survey, received rudimentary training, and were matched based on their diabetes-related self-management needs. They were asked to contact their partner weekly using the toll-free IVR calling line. At the completion of the 6-week period, participants completed follow-up surveys and brief telephone interviews.

RESULTS

Forty of 76 patients screened for eligibility by telephone agreed to participate, and 38 completed the 6-week intervention (50% of eligible patients). More than 80% of the pairs spoke at least once a week for 2 of the 6 weeks of the intervention. A total of 79% of the participants reported that the IVR system was easy to use, and 90% stated that they would be more satisfied with their health care if this type of peer support service were available. Of the participants, 70% found the calls helpful in managing diabetes symptoms, 73% reported that their partner helped them improve their self-care, and 70% stated that they helped their partner do things to stay healthy. There were significant improvements in participants' reported diabetes self-care self-efficacy between baseline and follow-up assessments (P < .01). Qualitative assessments suggested that participants found meaning and positive reinforcement for their own self-care through supporting their partner's efforts to manage diabetes.

CONCLUSIONS

An IVR peer support intervention is feasible, acceptable to patients, and may have positive effects on patients' diabetes self-management and health outcomes that warrant more rigorous evaluation in a randomized trial.

Rationale, design and conduct of a comprehensive evaluation of a primary care based intervention to improve the quality of life of osteoarthritis patients. The PraxArt-project: a cluster randomized controlled trial [ISRCTN87252339]

BACKGROUND

Osteoarthritis (OA) has a high prevalence in primary care. Conservative, guideline orientated approaches aiming at improving pain treatment and increasing physical activity, have been proven to be effective in several contexts outside the primary care setting, as for instance the Arthritis Self management Programs (ASMPs). But it remains unclear if these comprehensive evidence based approaches can improve patients' quality of life if they are provided in a primary care setting.

METHODS/DESIGN

PraxArt is a cluster randomised controlled trial with GPs as the unit of randomisation. The aim of the study is to evaluate the impact of a comprehensive evidence based medical education of GPs on individual care and patients' quality of life. 75 GPs were randomised either to intervention group I or II or to a control group. Each GP will include 15 patients suffering from osteoarthritis according to the criteria of ACR. In intervention group I GPs will receive medical education and patient education leaflets including a physical exercise program. In intervention group II the same is provided, but in addition a practice nurse will be trained to monitor via monthly telephone calls adherence to GPs prescriptions and advices and ask about increasing pain and possible side effects of medication. In the control group no intervention will be applied at all. Main outcome measurement for patients' QoL is the GERMAN-AIMS2-SF questionnaire. In addition data about patients' satisfaction (using a modified EUROPEP-tool), medication, health care utilization, comorbidity, physical activity and depression (using PHQ-9) will be retrieved. Measurements (pre data collection) will take place in months I-III, starting in June 2005. Post data collection will be performed after 6 months.

DISCUSSION

Despite the high prevalence and increasing incidence, comprehensive and evidence based treatment approaches for OA in a primary care setting are neither established nor evaluated in Germany. If the evaluation of the presented approach reveals a clear benefit it is planned to provide this GP-centred interventions on a much larger scale.

Psychological approaches to understanding and treating disease-related pain

Psychologists are increasingly involved in the assessment and treatment of disease-related pain such as pain secondary to arthritis or cancer. This review is divided into four sections. In the first section, we provide a conceptual background on this area that discusses the limitations of the biomedical model of disease-related pain and traces the evolution of psychosocial theories of pain. In the second section, we discuss special issues and challenges involved in working with persons having disease-related pain, including the reluctance of some persons to report pain and to become involved in psychological treatments for pain. Section three provides an overview of psychosocial research conducted on arthritis pain and cancer pain that addresses both psychosocial factors related to pain and psychosocial interventions for pain management. In the final section, we describe important future directions, including strategies for disseminating psychosocial treatments and disparities in pain management.

Lay health workers in primary and community health care

BACKGROUND

Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. However, little is known about the effectiveness of LHW interventions.

OBJECTIVES

To assess the effects of LHW interventions in primary and community health care on health care behaviours, patients' health and wellbeing, and patients' satisfaction with care.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care and Consumers and Communication specialised registers (to August 2001); the Cochrane Central Register of Controlled Trials (to August 2001); MEDLINE (1966- August 2001); EMBASE (1966-August 2001); Science Citations (to August 2001); CINAHL (1966-June 2001); Healthstar (1975-2000); AMED (1966-August 2001); the Leeds Health Education Effectiveness Database and the reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials of any intervention delivered by LHWs (paid or voluntary) in primary or community health care and intended to promote health, manage illness or provide support to patients. A 'lay health worker' was defined as any health worker carrying out functions related to health care delivery; trained in some way in the context of the intervention; and having no formal professional or paraprofessional certificated or degreed tertiary education. There were no restrictions on the types of consumers.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data onto a standard form and assessed study quality. Studies that compared broadly similar types of interventions were grouped together. Where feasible, the results of included studies were combined and an estimate of effect obtained.

MAIN RESULTS

Forty three studies met the inclusion criteria, involving more than 210,110 consumers. These showed considerable diversity in the targeted health issue and the aims, content and outcomes of interventions. Most were conducted in high income countries (n=35), but nearly half of these focused on low income and minority populations (n=15). Study diversity limited meta-analysis to outcomes for five subgroups (n=15 studies) (LHW interventions to promote the uptake of breast cancer screening, immunisation and breastfeeding promotion [before two weeks and between two weeks and six months post partum] and to improve diagnosis and treatment for selected infectious diseases). Promising benefits in comparison with usual care were shown for LHW interventions to promote immunisation uptake in children and adults (RR=1.30 [95% CI 1.14, 1.48] p=0.0001) and LHW interventions to improve outcomes for selected infectious diseases (RR=0.74 [95% CI 0.58, 0.93) p=0.01). LHWs also appear promising for breastfeeding promotion. They appear to have a small effect in promoting breast cancer screening uptake when compared with usual care. For the remaining subgroups (n=29 studies), the outcomes were too diverse to allow statistical pooling. We can therefore draw no general conclusions on the effectiveness of these subgroups of interventions.

AUTHORS' CONCLUSIONS

LHWs show promising benefits in promoting immunisation uptake and improving outcomes for acute respiratory infections and malaria, when compared to usual care. For other health issues, evidence is insufficient to justify recommendations for policy and practice. There is also insufficient evidence to assess which LHW training or intervention strategies are likely to be most effective. Further research is needed in these areas.

Nursing Telephonic Case Management and Pregnancy Outcomes of Mothers and Infants

Limited success has been achieved in identifying high-risk pregnant women via prenatal risk identification tools. The purposes of this study were to examine a risk assessment and nursing telephonic case management protocol used to identify high-risk mothers and infants, and to evaluate the costs and benefits of the protocol. This study involved a retrospective review of insurance data held by a large managed care organization (MCO). Analyzed data included information about current and past medical problems, and current lifestyle risk factors. Data analysis included frequencies, chi2, t tests, and logistic regression analysis. Pregnant MCO members experienced fewer high-risk conditions versus nonmembers. The overall pregnancy cost for a member was 1,818 dollars versus 4,587 dollars for a nonmember. Members experienced 2.5 times fewer babies hospitalized in the NICU, and significantly fewer mothers with high-risk conditions. The MCO program reduces costs and promotes better maternal and infant outcomes.

Psychological aspects of persistent pain: current state of the science

This article provides an overview of current research on psychological aspects of persistent pain. It is divided into 3 sections. In section 1, recent studies are reviewed that provide evidence that psychological factors are related to adjustment to persistent pain. This section addresses research on factors associated with increased pain and poorer adjustment to pain (ie, pain catastrophizing, pain-related anxiety and fear of pain, and helplessness) and factors associated with decreased pain and improved adjustment to pain (ie, self-efficacy, pain coping strategies, readiness to change, and acceptance). In section 2, we review recent research on behavioral and psychosocial interventions for patients with persistent pain. Topics addressed include early intervention, tailoring treatment, telephone/Internet-based treatment, caregiver-assisted treatment, and exposure-based protocols. In section 3, we conclude with a general discussion that highlights steps needed to advance this area of research including developing more comprehensive and integrative conceptual models, increasing attention to the social context of pain, examining the link of psychological factors to pain-related brain activation patterns, and investigating the mechanisms underlying the efficacy of psychological treatments for pain.

PERSPECTIVE

This is one of several invited commentaries to appear in The Journal of Pain in recognition of The Decade of Pain Research. This article provides an overview of current research on psychological aspects of persistent pain, and highlights steps needed to advance this area of research.

Management of osteoarthritis (OA) with an unsupervised home based exercise programme and/or patient administered assessment tools. A cluster randomised controlled trial with a 2x2 factorial design

BACKGROUND

Diary recording of pain and disabling activities in osteoarthritis (OA) is widely recommended, but, to our knowledge, its impact on symptoms has not been investigated. Exercise programmes have been shown to be effective when patients are closely supervised by nurses or physiotherapists; however, data are lacking on the efficacy of an unsupervised home based exercise regimen in patients with OA.

OBJECTIVES

To evaluate the clinical efficacy of patient administered assessment tools and an unsupervised home based exercise programme alone or in combination in patients with OA.

METHODS

The study was a 24 week, open cluster randomised controlled trial with a factorial design. Rheumatologists (n = 867) were assigned to four groups according to the treatment given: standardised tools (ST; n = 220), exercises (EX; n = 213), both tools and exercises (ST+EX; n = 213), or usual care (n = 221). Each rheumatologist was to enroll four patients who met the American College of Rheumatology criteria for OA (three with knee OA, one with hip OA). "Tools" consisted of weekly recording of pain and disabling activities in a diary. A home based exercise programme was performed daily at least four times per week with the aid of videotape and booklet. In addition to exercise and assessment, all patients received 12.5 mg or 25 mg of the non-steroidal anti-inflammatory drug rofecoxib once daily. Outcome variables were: pain (measured on a visual analogue scale, 0-100); Western Ontario and McMaster Universities Osteoarthritis Index, function subscale (0-100); and patient assessment of the quality of care (0-100).

RESULTS

Overall, 2957 patients with OA (2216 knee, 741 hip) were included. After 24 weeks, both pain and function improved in the ST, EX, ST+EX, and usual care groups (mean (SD) -17 (27), -20 (29), -15 (27), -19 (29); and -11 (19), -12 (19), -10 (19), -11 (20), respectively), without significant differences between groups. However, patients in the EX and ST+EX groups were more likely to agree that their rheumatologist had done his best to preserve their functional and physical activities.

CONCLUSION

Although patients' assessments favoured the exercise programme, results from this study failed to demonstrate a short term symptomatic effect of the two non-pharmacological treatments (weekly recording of condition and exercise) in patients with OA concurrently receiving nonsteroidal anti-inflammatory drugs.

A randomized clinical trial of a psychoeducational intervention to improve outcomes in systemic lupus erythematosus

OBJECTIVE

In a cross-sectional study, we previously identified 2 potentially modifiable risk factors for adverse outcomes in systemic lupus erythematosus (SLE): self-efficacy and social support. The goal of this study was to evaluate in a randomized controlled trial a theory-based intervention to improve patient self-efficacy and partner support to manage SLE.

METHODS

Patients with SLE ages 18 years and older who met the American College of Rheumatology criteria and were able to identify a partner (spouse or family member) were recruited from 2 academic medical centers and randomized into an experimental group or a control group. Patients in the experimental group and their partners received an intervention designed to enhance self-efficacy, couples communication about lupus, social support, and problem solving, in the form of a 1-hour session with a nurse educator followed by monthly telephone counseling for 6 months. Patients in the control group and their partners received an attention placebo, including a 45-minute video presentation about lupus, and monthly telephone calls. Measures of physical and mental health status, disease activity, and psychosocial factors were collected at baseline, 6 months, and 12 months. The effect of the intervention on physical and mental health and disease activity at 6 and at 12 months was modeled with linear regression and adjusted for baseline health status, disease activity, sociodemographic factors, treatment change, and psychosocial factors.

RESULTS

One hundred twenty-two patients (plus their partners) were enrolled and randomized as follows: 64 to the experimental intervention and 58 to the attention control group. The participants were predominantly white, approximately half were college educated, and the groups were balanced for sociodemographic factors. At 6 months, significantly higher scores for couples communication (P = 0.01) and problem-focused coping (P = 0.03) were seen in the experimental group compared with the control group. At 12 months (6 months after the intervention ended), social support was higher (4.4 versus 4.1; P = 0.03), self-efficacy was higher (7.2 versus 6.2; P = 0.02), couples communication was higher (3.5 versus 3.1; P = 0.03), and fatigue was lower (5.1 versus 6.3; P = 0.02) in the experimental group compared with the control group. Global mental health status at 12 months, as measured by the Short Form 36 survey, was 69 points in the experimental group compared with 58 points in the control group (P = 0.04). In multivariate models, adjusting for baseline covariates, scores for couple communication (P = 0.01) were significantly higher at 6 months, and scores for self-efficacy (P = 0.004) and global mental health status (P = 0.03) were significantly higher at 12 months in the experimental group compared with the control group, and the mean score for global physical function was higher by 7 points, which was a clinically meaningful change (P = 0.2). The mean score for fatigue was also significantly lower in the experimental group than in the control group (P = 0.05). SLE disease activity was unchanged by this intervention.

CONCLUSION

This randomized, controlled trial of a theory-based educational intervention in SLE demonstrated significantly higher scores for couple communication, self-efficacy, and mental health status, and lower fatigue scores in the experimental group compared with the control group. Because couple communication and self-efficacy appear to be modifiable risk factors, they may also be potential targets in more disadvantaged populations.

What is important in treating osteoarthritis? Whom should we treat and how should we treat them?

Most of the treatments used today for OA have a relatively weak evidence base to support their use, and their effect size is small. Many key questions about OA management remain unanswered, in part because of the strong bias toward research on single pharmaceutical agents rather than nonpharmacologic interventions and a comprehensive package of care involving pharmacologic and nonpharmacologic measures. Good management of OA involves the coordination of several different types of interventions provided by health care professionals; however, while a great deal of research is available on the use of individual treatments, there is a lack of information on how health services for patients who have OA should be organized. The problem is compounded by the fact that many people who have OA use complementary therapy as well as, or instead of, allopathic treatments despite the fact that most of the evidence suggests that many such interventions are no better than placebo [123], which might be because of the relatively small effects of most conventional nonsurgical treatment for OA and to the need for a more holistic, individualized approach to treatment than most conventional health professionals usually provide. For many people who have OA, the fear of side effects is a major barrier to the use of pharmacologic interventions [11]. The authors believe that future research in OA therapeutics should concentrate more on behavioral and physical interventions than on drugs, should examine packages of care involving combinations of treatment modalities, and should include a consideration of patient preferences. The authors also believe that the academic community striving to provide help for people who have OA should bear in mind the concept that there is "too much medicine" [37].

Comparison of clinic- and home-based rehabilitation programs after total knee arthroplasty

One hundred sixty patients (mean age, 68 +/- 8 years) having primary total knee arthroplasty were assigned randomly to two rehabilitation programs: (1) clinic-based rehabilitation provided by outpatient physical therapists; or (2) home-based rehabilitation monitored by periodic telephone calls from a physical therapist. Both rehabilitation programs emphasized a common home exercise program. Before surgery, and at 12 and 52 weeks after surgery, no statistically significant differences were observed between the clinic- and the home-based groups on any of the following measures: (1) total score on the Knee Society clinical rating scale; (2) total score on the Western Ontario and McMaster Universities Osteoarthritis Index; (3) total score on the Medical Outcomes Study Short Form; (4) pain scale of the Knee Society clinical rating scale; (5) pain scale of the Western Ontario and McMaster Universities Osteoarthritis Index; (6) functional scale of the Western Ontario and McMaster Universities Osteoarthritis Index; (7) distance walked in 6 minutes; (8) number of stairs ascended and descended in 30 seconds; and (9) knee flexion range of motion, on either the per protocol or the intent-to-treat or the analyses. After primary total knee arthroplasty, patients who completed a home exercise program (home-based rehabilitation) performed similarly to patients who completed regular outpatient clinic sessions in addition to the home exercises (clinic-based rehabilitation). Additional studies need to determine which patients are likely to benefit most from clinic-based rehabilitation programs.

[Therapeutic management of osteoarthritis in the beginning of the third millennium. Part II: non pharmacological strategies]

COMMENT
