Spinal fixation surgery for acute traumatic spinal cord injury.

BACKGROUND: If the spine is unstable following traumatic spinal cord injury (SCI), surgical fusion and bracing may be necessary to obtain vertical stability and prevent re-injury of the spinal cord from repeated movement of the unstable bony elements. It has been suggested that this spinal fixation surgery may promote early rehabilitation and mobilisation. OBJECTIVES: To answer the question: is there a difference in functional outcome and other commonly measured outcomes between people who have a spinal cord injury and have had spinal fixation surgery and those who have not? SEARCH STRATEGY: The following databases were searched: AMED, CCTR, CINAHL, DARE, EMBASE, HEED, HMIC, MEDLINE, NRR, NHS EED. Searches were updated in May 2003 and MEDLINE was searched again in May 2007. The reference lists of retrieved articles were checked. SELECTION CRITERIA: Randomised controlled trials and controlled trials that compared surgical spinal fixation, with or without decompression, to any other treatment, in patients with a traumatic SCI. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected studies. One reviewer assessed the quality of the studies and extracted data. MAIN RESULTS: No randomised controlled trials or controlled trials were identified that compared surgical spinal fixation surgery to other treatments in patients with a traumatic SCI. All of the studies identified were retrospective observational studies and of poor quality. AUTHORS' CONCLUSIONS: The current evidence does not enable conclusions to be drawn about the benefits or harms of spinal fixation surgery in patients with traumatic SCI. Well-designed, prospective experimental studies with appropriately matched controls are needed.

Etanercept and infliximab for the treatment of psoriatic arthritis: a systematic review.

OBJECTIVE: To review the evidence on the clinical effectiveness of etanercept and infliximab for the treatment of active and progressive psoriatic arthritis (PsA) in patients with an inadequate response to standard treatment (including DMARD therapy). METHODS: A systematic review was conducted. The literature search covered a range of 13 medical databases and submissions were provided by the manufacturers of etanercept and infliximab. Randomised controlled trials (RCTs) of etanercept or infliximab that reported outcomes of disease activity in PsA were reviewed. RESULTS: There were two good quality double-blind, placebo-controlled RCTs each for etanercept and infliximab. The results demonstrated that after initial treatment (12 weeks for etanercept and 14 or 16 weeks for infliximab) both drugs had statistically significant beneficial effects compared with placebo on ACR 20, 50 and 70, PsARC and HAQ scores. Efficacy was not dependent upon concomitant methotrexate. Results at 24 weeks indicated that the response to treatment is maintained. Effects on psoriasis were beneficial, particularly with infliximab. Uncontrolled radiographic assessment data at one year indicated a beneficial effect of both etanercept and infliximab on the progression of joint disease. CONCLUSION: Our review indicates that both etanercept and infliximab are efficacious in the treatment of PsA with beneficial effects on both joint and psoriasis symptoms and on functional status. There are limited data indicating that etanercept and infliximab can delay joint disease progression. Further long-term data are required to confirm and consolidate the evidence base for both drugs.

Sensitivity to change of AIMS2 and AIMS2-SF components in comparison to M-HAQ and VAS-pain.

OBJECTIVE: To examine sensitivity to change of Dutch versions of AIMS2 (arthritis impact measurement scales-2) and AIMS2-SF (short form) components, in comparison with M-HAQ (modified health assessment questionnaire) and the 100 mm visual analogue scale for pain (VAS-pain) in patients with rheumatoid arthritis. METHODS: 218 patients participated in a study on patient education. Participants completed the Dutch AIMS2, M-HAQ, and VAS-pain at baseline and after one year; 165 completed both assessments. The education programme did not have any effect on health status. Patients were classified according to change over one year in their responses to the AIMS2 question about general health perception: improved health (n = 32), no change (n = 101), and poorer health (n = 32). Changes in scores over one year were tested with paired t tests, and standardised response means were calculated for AIMS2 and AIMS2-SF components, M-HAQ total score, and VAS-pain in the three classifications of change in health perception. RESULTS: AIMS2 and AIMS2-SF physical, symptom, and affect components showed similar sensitivity to change. The physical and symptom components performed better than M-HAQ and VAS-pain. AIMS2 and AIMS2-SF social interaction and role components were not sensitive to changes in general health perception. The role component was only applicable in 63 patients, because the others were unemployed, disabled, or retired. CONCLUSIONS: AIMS2-SF is a good alternative to the AIMS2 long form for the assessment of health status in rheumatoid arthritis, and is preferable to M-HAQ and VAS-pain. Use of the AIMS2-SF makes it easier and less costly to collect data and reduces the burden on patients.

Patient education for adults with rheumatoid arthritis.

BACKGROUND: Because of the unpredictability people with arthritis face on a daily basis, patient education programmes have become an effective complement to traditional medical treatment giving people with arthritis the strategies and the tools necessary to make daily decisions to cope with the disease. OBJECTIVES: To assess the effectiveness of patient education interventions on health status in patients with rheumatoid arthritis. SEARCH STRATEGY: We searched MEDLINE, EMBASE and PsycINFO and the Cochrane Controlled Trials Register. A selection of review articles (see references) were examined to identify further relevant publications. There was no language restriction. SELECTION CRITERIA: Randomised controlled trials (RCT's) evaluating patient education interventions that included an instructional component and a non-intervention control group; pre- and post-test results available separately for RA, either in the publication or from the studies' authors; and study results presented in full, end-of-study report. MAIN RESULTS: Thirty-one studies with relevant data were included. We found significant effects of patient education at first follow-up for scores on disability, joint counts, patient global assessment, psychological status, and depression. A trend favouring patient education was found for scores on pain. Physician global assessment was not assessed in any of the included studies. The dimensions of anxiety and disease activity showed no significant effects. At final follow up no significant effects of patient education were found, although there was a trend favouring patient education for scores on disability. REVIEWER'S CONCLUSIONS: Patient education as provided in the studies reviewed here had small short-term effects on disability, joint counts, patient global assessment, psychological status and depression. There was no evidence of long-term benefits in adults with rheumatoid arthritis.

Psychometric properties of a Dutch short form of the Arthritis Impact Measurement Scales 2 (Dutch-AIMS2-SF).

OBJECTIVE: To evaluate the reliability and validity of a Dutch version of the Arthritis Impact Measurement Scales 2 short form (AIMS2-SF) and examine the agreement between the AIMS2 and AIMS2-SF in rheumatoid arthritis (RA) patients. METHODS: Data were collected from 587 RA patients from three studies. Patients completed the Dutch-AIMS2, Modified Health Assessment Questionnaire (M-HAQ), and Visual Analogue Scale for pain (VAS-pain), and clinical data were collected to calculate the Disease Activity Score 28 (DAS28). Short-form component scores were calculated from the AIMS2 long-form data. In addition, a Modified Symptom component score was calculated by replacing item 42 with item 38 as was suggested by Haavardsholm et al. [7] for the Norwegian version. RESULTS: The internal consistency of the Physical, Symptom and Affect components was good (Cronbach's alpha= 0.75-0.87), moderate for the Role component (alpha=0.62) but rather low for the Social Interaction (0.51) component. Replacing item 33 with item 31 of the long-form AIMS2 increased internal consistency for the Social Interaction component to 0.63. Test-retest reliability of the AIMS2-SF components was high (intraclass correlation coefficients >0.70). Mean scores of the AIMS2-SF were generally close to those from the AIMS2, but the limits of agreement were rather wide. Both the Modified Symptom and Modified Social Interaction components showed better agreement than the original short-form components. Plots of differences between AIMS2 and AIMS2-SF against the mean of the two scores for the five components showed that the differences varied over the range of the measurements. Factor analysis confirmed the three-factor structure, with a physical, psychological and social dimension that has been found for the Dutch-AIMS2 long form. Correlations of the AIMS2-SF components with M-HAQ total score, functional class, VAS-pain and DAS28 were very similar to the correlations for the original AIMS2. CONCLUSION: The Dutch-AIMS2-SF, with Modified Symptom and Social Interaction components has good psychometric properties, similar to those of the Dutch-AIMS2 long form.

At final follow up no significant effects of patient education were found. REVIEWER'S CONCLUSIONS: Patient education as provided in the studies reviewed here had moderate short-term effects on patient global assessment, and small short-term effects on disability, joint counts and psychological status. There were no long-term benefits.

General health status measures for people with cognitive impairment: learning disability and acquired brain injury.

BACKGROUND: Currently there is a wide range of health status measures that aim to assess general health status in people with cognitive impairment. However, the validity and/or applicability to this patient group are largely unknown. This has implications for the assessment of treatment outcomes and rehabilitation, for prognostic purposes, for planning services, and for determining the benefits and adverse effects of health technologies targeted at these patient groups. OBJECTIVES: (1) To identify the general health status measures that have been validated in patients with cognitive impairment. (2) To assess the extent to which these measures have been validated. (3) To draw out the implications of the findings for the use of existing measures and for future primary research in this area. METHODS. SELECTION CRITERIA: Studies that assessed general health status in people with cognitive impairment due to acquired brain injury (traumatic brain injury, cerebro-vascular accident or multiple sclerosis (MS)) or learning disability (LD) were included in the review. Studies that used general health status instruments measuring only one general health dimension, and studies that only featured participants with cognitive impairment due to dementia were excluded. METHODS. SEARCH STRATEGY: A wide range of relevant databases were searched for studies on cognitive impairment, general health status measures, and validation of health status measures. A handsearch of general health status bibliographies was also conducted. Data were collected on the general health status measure used, the population characteristics, aims of the study, validity details, and conclusions. RESULTS: The review includes data from 71 studies, reported in 83 separate publications. In total 34 different general health status measures were described in the 83 publications, with the Sickness Impact Profile (SIP) and the Short Form-36 (SF-36) the most frequently used measures (20 and 19 studies, respectively). These studies included a total of 98 instrument validations, 52 of which definitely or probably included people with cognitive impairment. Six measures were extensively validated (quality scores ranged from 0.25 to 0.5, on a scale from 0 to 1) in studies in which more than 50% of the respondents were people with cognitive impairment. A further three measures were also validated in studies in which more than 50% of the respondents were people with cognitive impairment, but their level of validation was more limited (quality scores ranged from 0.1 to 0.2). Five measures were validated in studies in which 20-50% of the respondents were cognitively impaired, which may limit their relevance to participants with cognitive impairment (quality scores ranged from 0.1 to 0.6). The SF-36 was also validated in two studies in which 20-50% of the respondents were cognitively impaired and the quality score was 0.3. Finally, nine of the measures were only validated in studies in which less than 20% of the respondents were cognitively impaired. For these measures it was unclear whether the findings applied to people with cognitive impairment. CONCLUSIONS: Very few measures have been validated specifically for cognitively impaired respondents. Studies where at least 50% of the respondents were cognitively impaired generally showed poorer validity results compared with studies with fewer cognitively impaired persons, indicating that general health status measures designed for the general population are not automatically suitable for people with cognitive impairment. The few measures that were specifically developed for people with cognitive impairment also reported poor validity results. Therefore, there are no validated instruments available for use in cognitively impaired respondents; existing measures, specifically designed for use in these populations, should be used with caution. The most promising measure is the MS-Quality of Life Interview (MS-QLI) for MS patients. The MS-QLI was thoroughly validated in 300 MS patients and the results were good, except for the 'social function' subscale. However, only 20-50% of the respondents in this study had cognitive impairment. Most information on the validity of general health status measures was found in studies among people with LD. For these patients, six measures were found that have been validated in a populations where more than 50% of the respondents were cognitively impaired LD patients. CONCLUSIONS: (1) Existing general health status measures should be used with caution in individuals with cognitive impairments. (2) There is no evidence to indicate the most suitable general health status measure for use in economic evaluations of cognitive impairment. (3) There is little evidence to support the validity of proxy assessments in cognitively impaired populations. (ABSTRACT TRUNCATED)

Perceptions about perceived functional disabilities and pain of people with rheumatoid arthritis: differences between patients and their spouses and correlates with well-being.

OBJECTIVE: In this study we examined the differences in perceptions of the patient's health status between rheumatoid arthritis (RA) patients and their spouses, and correlates of these differences with patients' and spouses' well-being. METHODS: A sample of 188 couples with one member receiving treatment for RA were selected from the rheumatology clinics in Twente, The Netherlands. The mean age of both RA patients and spouses was 56 years. Respondents completed questionnaires, including estimations of both patients and spouses on the patient's functional disabilities and pain, and scales on affect and marital commitment for patients and spouses. RESULTS: Differences in estimations of patients and spouses were considerable. Both over- and underestimations of the patient's functional disabilities by the spouse were associated with the patient's poorer mental health status. Overestimations of the patient's functional disabilities were associated with poorer mental health among spouses. CONCLUSION: It is essential that any support intended by the spouse is in accordance with the patient's needs. If the patient's condition is misperceived by the spouse, this can lead to ineffective and inappropriate support being given.

Problematic and positive support in relation to depression in people with rheumatoid arthritis.

This study focuses on the associations of both positive and problematic aspects of social support with depression in patients with rheumatoid arthritis. In a hierarchical multiple regression analysis we found that stressors such as functional limitations and pain are strongly related to depression. Positive and problematic support each explain an additional significant portion of the variance in depression. More positive support is associated with fewer feelings of depression and more problematic support is associated with more feelings of depression. An interaction effect between positive and problematic social support indicates that the negative aspects of problematic support may be partly diminished by positive support (buffering effect). Patients receiving more problematic support and less positive support experience the most feelings of depression.

Fatigue in rheumatoid arthritis: the role of self-efficacy and problematic social support.

OBJECTIVE: To examine the relationship of fatigue in people with rheumatoid arthritis (RA) with self-efficacy, positive and problematic aspects of social support, and demographic and disease-related variables. METHOD: Out-patients with at least 5 yr RA were studied. Fatigue was measured with a visual analogue scale. Other variables included were: positive social support [Social Support List-Interactions (SSL12-I)] and problematic social support; self-efficacy towards coping with RA and towards mobilizing support; health status (Dutch-AIMS2); and laboratory tests: erythrocyte sedimentation rate (ESR), haemoglobin (Hb) and rheumatoid factor (RF); and disease duration. RESULTS: A total of 229 out-patients were included. Fatigue correlated with all scales of the Dutch-AIMS2: with pain, physical function and affect (P < 0.001). There was no significant correlation with social support, but there was a highly significant correlation of fatigue with problematic social support (P < 0.001). Both forms of self-efficacy correlated strongly with fatigue: patients with high self-efficacy expectations towards coping with RA, and towards mobilizing the social network (P < 0.001), had less fatigue. In the regression analysis to explain the variation in fatigue, only pain, self-efficacy expectations towards coping with RA, and towards asking for help and problematic social support remained significant. CONCLUSIONS: Fatigue can to a large extent (37%) be explained by pain, self-efficacy towards coping with RA, and towards asking for help and problematic social support. It is known that self-efficacy can be enhanced by self-management courses and it may thus be possible to improve fatigue.

The supply of and demand for informal and professional care for patients with rheumatoid arthritis.

The objective of this study is to determine supply of, and demand for, informal care for rheumatoid arthritis (RA) patients and to evaluate the factors that contribute to the amounts of help needed and received from professional and informal care providers at home. Data were collected by questionnaire from 229 RA patients and 174 informal caregivers. Most of the help required is also received, though 24% of the patients did not receive help for one or more tasks. Most help given at home is by informal caregivers. The amount of help needed is related primarily to the patient's physical condition, sex, and self-efficacy expectations towards coping with RA. The amount of help received from informal caregivers is largely explained by the physical condition and the marital status of the patient, the sex of the caregiver, the patient's self-efficacy expectations towards coping with RA, and the age of the patient. The amount of help received from health professionals is related primarily to the marital status and the physical condition of the patient.

Coordinated individual education with an arthritis passport for patients with rheumatoid arthritis.

OBJECTIVE: To evaluate the effects of a program for individual education in combination with the use of an arthritis passport. METHODS: We studied 3 groups of patients with rheumatoid arthritis. The first experimental group received educational materials and followed the program under the guidance of their regular providers of health care whose activities were coordinated through arthritis passports. The second experimental group only received education materials; the control group received only usual care. RESULTS: There were no effects on self-efficacy expectations, knowledge, health status, or behavior in either experimental group. Opinions of general practitioners, physiotherapists, and visiting nurses concerning the arthritis passport were very positive, but rheumatologists' opinions were not. Opinions on coordination of care were more positive among the physiotherapists of the experimental group. CONCLUSIONS: Individual education for patients with rheumatoid arthritis by health care providers during routine consultations, as implemented in this program, had no effect on self-efficacy expectations, knowledge, health status, or health behavior. Likewise, the distribution of educational materials by itself without the involvement of health care providers had no effect. The use of the arthritis passport improved coordination of care, especially for physiotherapists.

Evaluation of a Dutch version of the AIMS2 for patients with rheumatoid arthritis.

DUTCH-AIMS2, a Dutch version of AIMS2 and successor to DUTCH-AIMS, is an instrument to assess health status among patients with rheumatic diseases. It provides measurements of 12 areas of health status on scales for health status proper, satisfaction, attribution and arthritis impact. We assessed the reliability of its scales in terms of internal consistency and their validity according to both internal standards and external standards. Correctly completed questionnaires were returned by 231 RA patients and 131 controls. Internal consistency coefficients for the health status scales ranged from 0.66 and 0.89, but most exceeded 0.80. Within-scale factor analyses produced single factors in all composite health status scales for both patients and controls, with only two exceptions. Factor analysis also identified a physical, social and psychological dimension among 11 areas of health. External validity was established by strong correlations between DUTCH-AIMS2 health status scales and functional class, laboratory parameters, and self-assessments of fatigue, loneliness, pain, functional disability and social support. DUTCH-AIMS2 is acceptably reliable and valid for use in a variety of settings.

Group education for patients with rheumatoid arthritis.

Patients with rheumatoid arthritis must learn to adjust their exercise, rest and medication to the varying activity of the disease. Patient education can help patients in making the right decisions about adjustments in their treatment regimen and in attaining "self-management" behaviors. We developed a group education program based on social learning theory and the 'Arthritis Self-Management Course' developed in the USA by Lorig. Goal of the program is the strengthening of self-efficacy, outcome expectations and self-management behaviors of RA patients which may lead to better health status. The program has been evaluated in an experimental design. We established significant positive effects of the group training on functional disability, joint tenderness, practice of relaxation and physical exercises, self-management behavior, outcome expectations, self-efficacy function and knowledge. After 14 months we still found effects on practice of physical exercises, self-efficacy function and knowledge.
