The need for collaboration in health and social welfare is well documented internationally. It is related to the improvement of services for the users, particularly target groups with multiple problems. However, there is still insufficient knowledge of the complex area of collaboration, and the interprofessional literature highlights the need to develop adequate research approaches for exploring collaboration between organizations, professionals and service users. This paper proposes a conceptual framework based on interorganizational and interprofessional research, with focus on the concepts of integration and collaboration. Furthermore, the paper suggests how two measurement instruments can be combined and adapted to the welfare context in order to explore collaboration between organizations, professionals and service users, thereby contributing to knowledge development and policy improvement. Issues concerning reliability, validity and design alternatives, as well as the importance of management, clinical implications and service user involvement in future research, are discussed.  相似文献

OBJECTIVES: Some conclusions from the Cochrane Database of Systematic Reviews (CDSR) seem volatile in areas of controversy and have recently changed conclusions. With this perspective in mind we decided to test the validity and sensitivity of negative conclusions in a systematic review of low-level laser therapy (LLLT) for osteoarthritis (OA) from the Cochrane Library was valid and robust. SETTINGS/LOCATION: None as this was a systematic review of literature. DESIGN: Validity was tested against a 9-item checklist for systematic reviews. Review selections were analyzed for possible discrepancies between trial and review reports and omissions of relevant trials and data. Data from discrepancies and omissions were then entered into sensitivity and subgroup analyses. OUTCOME MEASURES: Continuous and dichotomous data for pain SUBJECTS: Patients with osteoarthritis. INTERVENTIONS: LLLT. RESULTS: Only clinicians who had performed LLLT trials, and had negative results were invited into the review group. The review was oblivious to findings published after 1993 about physiologic mechanisms and dose response patterns for LLLT. We found 18 questionable selections that favored a negative review conclusion in 17 of 18 cases. These were largely omissions of relevant positive data and selective inclusion of negative data from trials with small, ineffective doses. When existing and omitted data from relevant trials were combined, results changed from negative to significantly positive for continuous and categorical data. Subgrouping trials by location and recommended doses taken from current guidelines, revealed a highly significant effect of LLLT for treating knee OA. CONCLUSIONS: The results of this CDSR was not robust and seems to be colored by questionable selections or omissions. For alternative pain therapies, it should be considered if lack of expertise on therapy mechanisms, or conflicts of interests with competing pain drug manufacturers, may bias conclusions. Review groups should recruit a balanced mix of current views and expertise and expand the use of sensitivity analyses to improve quality of CDSRs in areas of controversy.  相似文献

The United Nations Convention on the Rights of the Child emphasizes the importance of allowing children and adolescents to influence decisions that are important to them following their age and maturity. This paper explores the principles, practices, and implications around using parental versus child/adolescent consent when participating in social science research and policy development. Experiences from two studies are presented: The Confronting Obesity: Co-creating policy with youth (CO-CREATE) and the Health Behaviour in School-aged Children (HBSC) study, a World Health Organization (WHO) Collaborative Cross-National study. Although parental consent may be an important gatekeeper for protecting children and adolescents from potentially harmful research participation, it may also be considered an obstacle to the empowerment of children and adolescents in case they want to share their views and experiences directly. This paper argues that evaluation of possible harm should be left to ethics committees and that, if no harm related to the research participation processes is identified and the project has a clear perspective on collaborating with the target group, adolescents from the age of 12 years should be granted the legal capacity to give consent to participate in the research project. Collaboration with adolescents in the development of the research project is encouraged.  相似文献
