This systematic review points to the potential of preventing SRDs by improving the psychosocial work environment. However, more prospective studies are needed on the remaining factors, exposure assessment and the relative contributions of single factors, in order to enable consistent assessment of the work-relatedness of SRDs by occupational physicians.

Background Depression is associated with negative work outcomes such as reduced work participation (WP) (e.g., sick leave duration, work status) and work functioning (WF) (e.g., loss of productivity, work limitations). For the development of evidence-based interventions to improve these work outcomes, factors predicting WP and WF have to be identified. Methods This paper presents a systematic literature review of studies identifying factors associated with WP and WF of currently depressed workers. Results A total of 30 studies were found that addressed factors associated with WP (N = 19) or WF (N = 11). For both outcomes, studies reported most often on the relationship with disorder-related factors, whereas personal factors and work-related factors were less frequently addressed. For WP, the following relationships were supported: strong evidence was found for the association between a long duration of the depressive episode and work disability. Moderate evidence was found for the associations between more severe types of depressive disorder, presence of co-morbid mental or physical disorders, older age, a history of previous sick leave, and work disability. For WF, severe depressive symptoms were associated with work limitations, and clinical improvement was related to work productivity (moderate evidence). Due to the cross-sectional nature of about half of the studies, only few true prospective associations could be identified. Conclusion Our study identifies gaps in knowledge regarding factors predictive of WP and WF in depressed workers and can be used for the design of future research and evidence-based interventions. We recommend undertaking more longitudinal studies to identify modifiable factors predictive of WP and WF, especially work-related and personal factors.Electronic supplementary materialThe online version of this article (doi:10.1007/s10926-009-9224-x) contains supplementary material, which is available to authorized users.

The objective of this study was to provide an overview of the prognostic factors for return to work and employment of cancer survivors. Cohort studies were selected if the population consisted of cancer patients between 18 and 65 years of age, with return to work, employment or equivalent concepts as main outcome measure, studying at least one prognostic factor. The methodological quality of the included studies and level of evidence for each prognostic factor were assessed. Twenty-eight cohort studies met the inclusion criteria. Heavy work and chemotherapy were negatively associated with return to work. Less invasive surgery was positively associated with return to work. Breast cancer survivors had the greatest chance of return to work. Old age, low education and low income were negatively associated with employment. Moderate evidence was found for extensive disease being negatively associated with both return to work and employment, and for female gender being negatively associated with return to work. The review shows that in cancer survivors, a limited number of prognostic factors of return to work and employment can be identified. Physicians primarily engaged in the process of vocational rehabilitation of cancer survivors should be aware of the potential role these factors exert.

BackgroundPatient empowerment is growing in popularity and application. Due to the increasing possibilities of the Internet and eHealth, many initiatives that are aimed at empowering patients are delivered online.ObjectiveOur objective was to evaluate whether Web-based interventions are effective in increasing patient empowerment compared with usual care or face-to-face interventions.MethodsWe performed a systematic review by searching the MEDLINE, EMBASE, and PsycINFO databases from January 1985 to January 2009 for relevant citations. From the 7096 unique citations retrieved from the search strategy, we included 14 randomized controlled trials (RCTs) that met all inclusion criteria. Pairs of review authors assessed the methodological quality of the obtained studies using the Downs and Black checklist. A meta-analysis was performed on studies that measured comparable outcomes. The GRADE approach was used to determine the level of evidence for each outcome.ResultsIn comparison with usual care or no care, Web-based interventions had a significant positive effect on empowerment measured with the Diabetes Empowerment Scale (2 studies, standardized mean difference [SMD] = 0.61, 95% confidence interval [CI] 0.29 - 0.94]), on self-efficacy measured with disease-specific self-efficacy scales (9 studies, SMD = 0.23, 95% CI 0.12 - 0.33), and on mastery measured with the Pearlin Mastery Scale (1 study, mean difference [MD] = 2.95, 95% CI 1.66 - 4.24). No effects were found for self-efficacy measured with general self-efficacy scales (3 studies, SMD = 0.05, 95% CI -0.25 to 0.35) or for self-esteem measured with the Rosenberg Self-Esteem Scale (1 study, MD = -0.38, 95% CI -2.45 to 1.69). Furthermore, when comparing Web-based interventions with face-to-face deliveries of the same interventions, no significant (beneficial or harmful) effects were found for mastery (1 study, MD = 1.20, 95% CI -1.73 to 4.13) and self-esteem (1 study, MD = -0.10, 95% CI -0.45 to 0.25).ConclusionsWeb-based interventions showed positive effects on empowerment measured with the Diabetes Empowerment Scale, disease-specific self-efficacy scales and the Pearlin Mastery Scale. Because of the low quality of evidence we found, the results should be interpreted with caution. The clinical relevance of the findings can be questioned because the significant effects we found were, in general, small.

Objective To summarise available evidence on diagnostic tests that might help primary care physicians to identify patients with an increased risk for colorectal cancer among those consulting for non-acute lower abdominal symptoms. Data sources PubMed, Embase, and reference screening. Study eligibility criteria Studies were selected if the design was a diagnostic study; the patients were adults consulting because of non-acute lower abdominal symptoms; tests included signs, symptoms, blood tests, or faecal tests. Study appraisal and synthesis methods Two reviewers independently assessed quality with a modified version of the QUADAS tool and extracted data. We present diagnostic two by two tables and pooled estimates of sensitivity and specificity. We refrained from pooling when there was considerable clinical or statistical heterogeneity. Results 47 primary diagnostic studies were included. Sensitivity was consistently high for age ≥50 (range 0.81-0.96, median 0.91), a referral guideline (0.80-0.94, 0.92), and immunochemical faeces tests (0.70-1.00, 0.95). Of these, only specificity of the faeces tests was good. Specificity was consistently high for family history (0.75-0.98, 0.91), weight loss (0.72-0.96, 0.89), and iron deficiency anaemia (0.83-0.95, 0.92), but all tests lacked sensitivity. None of these six tests was (sufficiently) studied in primary care. Conclusions Although combinations of symptom and results of immunochemical faeces tests showed good diagnostic performance for colorectal cancer, evidence from primary care is lacking. High quality studies on their role in the diagnostic investigation of colorectal cancer in primary care are urgently needed. INTRODUCTIONColorectal cancer is the second most common cancer in Europe.1 2 The five year survival rate for early stage colorectal cancer is greater than 90%, whereas the five year survival rate for those diagnosed with widespread

We found moderate-quality evidence that CBT did not significantly reduce time until partial RTW and low-quality evidence that it did not significantly reduce time to full RTW compared with no treatment. Moderate-quality evidence showed that PST significantly enhanced partial RTW at one-year follow-up compared to non-guideline based care but did not significantly enhance time to full RTW at one-year follow-up. An important limitation was the small number of studies included in the meta-analyses and the small number of participants, which lowered the power of the analyses.

ObjectiveThe authors sought to determine whether intensive follow-up improves 5-year survival rates in patients with colorectal cancer who were operated on for cure. Summary Background DataIntensive follow-up of patients with colorectal cancer is still controversial. The present uncertainty in regard to the value of intensive follow-up could be the result of the absence of prospective randomized studies comparing patients with and without follow-up. MethodsStudies comparing two follow-up programs of different intensities were identified in the medical literature and were aggregated in a meta-analysis using the "random effects method." Seven nonrandomized studies describing 3283 patients were analyzed. ResultsPatients with intensive follow-up did have 9% better 5-year survival rates than did those with minimal or no follow-up, only when intensive follow-up included carcinoembryonic antigen (CEA) assays. In addition, more asymptomatic recurrences were detected and more recurrences were resected in patients with intensive follow-up. ConclusionsThis meta-analysis indicated that intensive follow-up using CEA assays can identify treatable recurrences at a relatively early stage. Treatment of these recurrences appears to be associated with improved 5-year survival rates. However, not all intensive follow-up strategies will be equally effective. Follow-up may yield the best results if diagnostic tests are used only to detect those recurrences that can be operated on with curative intent and when follow-up is "individualized," according to patient characteristics.Colorectal cancer is the third most common neoplasm dergo primary tumor resection for cure, more than one in Western countries and the second leading cause of halfwill eventually die of their disease.

GBC did not differ in RTW compared with UC, but may be beneficial for the majority of workers with minor stress-related disorders.
