A three-stage Delphi investigation was undertaken over a 4-month period in a primary care trust to identify the perceived clinical needs of nurses. Practice nurses, district nurses, health visitors and community hospital nurses all participated. In round 1, there were 28 replies from these groups of nurses, in round 2 there were 31, and in round 3 there were 25 replies. In round 1, 77 issues (excluding duplications) were identified. These were separated into three themes according to the most appropriate method for addressing the issue: education (29 issues), research (16 issues) and management (32). In round 2, the issues were redistributed in the three areas and staff were asked to choose the ten most important issues from education, research and management. Finally, in round 3 the ten issues in education, research and management were prioritized in terms of the "most pressing". The most pressing education need was recognizing accountability; the most pressing research need was caseload/dependency scoring--matching staff levels to workload, and the most pressing management need was risk management, e.g. staff safety. The results have identified locally that there is a gap between the modernization agenda and what nursing staff consider to be the issues that need addressing locally. If measures are not put in place to address these local issues, there is a danger that nurses will not take a full and active role in the modernization of the NHS.  相似文献

Muscle strength changes following multi-level surgery in cerebral palsy and the impact of rehabilitation on functional recovery are largely unknown. The aim of this study was to quantify lower limb muscle strength changes in children with spastic diplegia after multi-level orthopaedic surgery and to compare the efficacy of progressive resistance strengthening (RS) versus active exercise (AE).

Twenty children with spastic diplegia (mean age 12.5 years) participated in this prospective randomised controlled trial. Participants underwent multi-level orthopaedic surgery. Routine physiotherapy commenced immediately after surgery. At 6 months post-operatively, children were randomly assigned to the resistance strengthening RS (n = 11) or active exercise AE (n = 9) group and received intensive physiotherapy for 6 weeks. Gait, motor function and maximum isometric muscle strength in five lower limb muscle groups were measured pre-operatively and at 6 months (before and after intensive physiotherapy) and 12 months. As part of the study, we developed and validated a myometry protocol.

Despite kinematic improvements, there was significant reduction of muscle strength (p < 0.05) in all muscle groups at 6 months post-operatively. Following 6 weeks of intensive physiotherapy, both groups showed significant improvement in muscle strength, GMFM scores and gait parameters. Resistance training showed some advantages over active exercise. At 1 year after surgery, strength did not reach pre-operative values in some muscle groups but the benefit from physiotherapy was maintained.

In conclusion, we quantified objectively the reduction in muscle strength 6 and 12 months following multi-level surgery. Furthermore, we demonstrated significant improvement in muscle strength, gait and function following post-operative strength training.  相似文献

Medical conferences provide a forum for the rapid dissemination of research directly to health professionals and academics. However, the published record of poster and oral presentations from these meetings is usually limited to abstracts. We aimed to assess how many wound studies presented as conference abstracts were eventually published in journals and to identify the factors that predicted publication. The study was a retrospective review. We identified abstracts relating to oral and poster presentation from two large wound conferences. Following data extraction from the abstracts, a systematic search was conducted to examine if the research was subsequently published as a journal article. A time-to-event analysis was conducted to assess predictive associations between features of the research reported in the conference abstracts and time to full publication. In total, 492 abstracts from two European wound care conferences were identified (467 after exclusions). Of the abstracts included, 60% (279) were for posters and 40% (188) were for oral presentations. Over half of the abstracts (53%) reported results from case studies or case series design. In total, only 57 (12%) of the abstracts included resulted in a related publication. Analysis suggested that those studies reporting positive findings were significantly more likely to be published (hazard ratio 1.79, P= 0.001, 95% CIs 1.26-2.55). Few studies presented as conference abstracts at these two wounds conferences were subsequently published. This may be because of the low methodological quality of studies accepted for poster or oral presentation.  相似文献

Cross-border reproductive care (CBRC) has attracted considerable attention in media and professional publications. The aim of this review is to present a critical narrative overview of the published evidence on CBRC. A systematic search of key academic databases was undertaken with no time restrictions set for publication. This was supplemented by additional searches of key websites, reference chaining and enquiries to people working in the field. A total of 54 items are included in the review, including both empirical research studies (18) and debate papers (36). The key themes discussed are: terminology and definitions; incidence; experiences; explanations; implications; and policy responses. Significant methodological limitations and gaps in the literature are identified. Evidence on incidence is scant, though it suggests that CBRC is increasing. The literature suggests legal, social and political drivers, which vary in importance geographically and between individuals. Limited findings on patient perceptions suggest a broadly positive patient experience. Suggested policy responses include prohibition, regulatory harmonization and harm minimization. There is a need for better international data collection tools and both quantitative and qualitative work which encompasses views of patients, donors, surrogates and professionals and which explores the implications for healthcare services in sending countries.  相似文献
