ObjectiveTo examine the effectiveness of a nurse-led multidisciplinary self-management program (NMSP) on self-management behaviors, self-efficacy, health-related quality of life (HRQoL) and unplanned health service utilization (HSU) among Chinese patients with coronary heart disease (CHD) in communities.MethodsA randomized controlled trial with repeated measurements was used. A convenience sample of 144 participants was recruited from a community health center in China. All participants were randomly assigned to an intervention group (n = 72) in the newly developed NMSP or a control group (n = 72) in routine care. Outcome measurement was performed at baseline, 3 months and 6 months using Coronary Artery Disease Self-Management Scale (CADSs), Self-efficacy for Chronic Disease 6-item Scale (SECD6), and Short Form-12 health survey questionnaire (SF-12).ResultsOver the six months, the two groups reported significant differences in disease medical and emotional management of CADSs, confidence in symptom and disease management of SECD6, physical and mental component summary of SF-12, as well as emergency and outpatient visits of unplanned HSU.ConclusionsThe NMSP improves self-management behaviors, self-efficacy, HRQoL and reduces unplanned HSU among CHD patients in communities.Practice implicationsThis study provides an effective approach to empower CHD patients with emphasizing on collaboration support of health professionals in communities.  相似文献

BackgroundThe association of treatment volume and oncological outcome of rectal cancer patients undergoing multidisciplinary treatment is subject of an ongoing debate. Prospective data on long-term local control and overall survival (OS) are not available so far. This study investigated the long-term influence of hospital and surgeon volume on local recurrence (LR) and OS in patients with locally advanced rectal cancers.MethodsIn a post-hoc analysis of the randomized phase III CAO/ARO/AIO-94 trial after a follow-up of more than 10 years, 799 patients with stage II/III rectal cancers were evaluated. LR-rates and OS were stratified by hospital recruitment volume (≤20 vs. 21–90 vs. >90 patients) and by surgeon volume (≤10 vs. 11–50 vs. >50 procedures).ResultsPatients treated in high-volume hospitals had a longer OS than those treated in hospitals with medium or low treatment volume (p = 0.03). The surgeon volume was adversely associated with LR (p = 0.01) but had no influence on overall survival. The positive effect of neoadjuvant chemoradiation (CRT) on local control was the strongest in patients being operated by medium-volume surgeons, less in patients being operated by high-volume surgeons and missing in those being operated by low-volume surgeons.ConclusionsPatients with locally advanced rectal cancers might benefit from treatment in specialized high-volume hospitals. In particular, the surgeon volume had significant influence on long-term local tumour control. The effect of neoadjuvant CRT on local tumour control may likewise depend on the surgeon volume.  相似文献

应重视口腔颌面部恶性肿瘤的综合序列治疗   总被引:11,自引:2,他引:9  
口腔颌面部恶性肿瘤约占全身恶性肿瘤的3%,虽然所占比例不高,但l大l其解剖部位特殊.涉及美观和重要的生理功能,冈此对患者机体和心理的影响不容忽视。早期(Ⅰ、Ⅱ期)口腔颌面部恶性肿瘤无论采用手术和(或)放射治疗,均能取得良好效果。但遗憾的是,大多数患者就诊时,已属局部一区域晚期(Ⅲ、Ⅳ期)。由于受到局部解剖和维持功能的限制,单纯通过扩大手术切除范围和改进现有手术技术,除能改善患者生存质量外,已无法提高此类患者的生存率,延长其生存时间。  相似文献

Background:  Sample sizes in studies of childhood chronic fatigue remain small and there is a need to integrate research findings and establish common criteria.
Method:  This is a detailed report of 20 children with medically unexplained fatigue, referred to as Chronic Fatigue Syndrome (CFS). It includes an uncontrolled outcome study of treatment based on a pragmatic cognitive-behavioural model adapted for children at Great Ormond Street Hospital for Children.
Results:  The data revealed psychological distress at 30 times the prevalence found in the normal child population, with specific high-ranking symptoms, including headache, social withdrawal and decreased appetite. Onset tended to occur at 11 years of age with some earlier problems at school age, suggesting it might be possible to identify those most at risk. Follow-up demonstrated improvement in 87% of the sample (parental report), a significant increase in school attendance and a significant decrease in symptom severity. Factors associated with good outcome were short duration of fatigue (less than a year) and behaviours that tended to combat the cycle of avoidance, such as carefully planned home-tuition.
Conclusions:  Recording a comprehensive range of symptoms and factors facilitates comparisons within and between child studies. It is proposed that symptom severity is a particularly relevant measure for Chronic Fatigue Syndrome which is characterised by persisting symptoms.  相似文献

【目的】 结合国家对学术期刊发展的指导政策,为中国英文学术期刊发展路径提供思路、数据支撑和理论指导。【方法】 以中国ESI高被引科学家和ESI期刊在ESI 22个学科的分布为研究对象,对两者分别在世界ESI高被引科学家和世界ESI高被引期刊中的发展脉络进行分析。【结果】 两类研究对象的发展现状不均衡,中国ESI期刊行业布局尚未对中国ESI高被引学者的跨学科发展趋势做出响应。【结论】 在中国基础学科的高被引科学家不断涌现的背景下,除了大力发展基础学科的高质量期刊以外,扶持交叉领域期刊、综合性学术期刊以及文科和应用型学科期刊的发展对促进中国ESI期刊学科分布均衡发展有重要意义;中国ESI期刊应将扶植国内科研工作者作为首要使命。  相似文献
