This article describes the rationale, design and methodology of the Building research initiative group: chronic illness management and adherence in transplantation (BRIGHT) study. This study of heart transplant patients will: (1) describe practice patterns relating to chronic illness management; (2) assess prevalence and variability of non-adherence to the treatment regimen; (3) determine the multi-level factors related to immunosuppressive medication non-adherence.
The unaltered long-term prognosis after heart transplantation underscores an urgent need to identify and improve factors related to survival outcomes. The healthcare system (e.g. level of chronic illness management implemented) and patient self-management are major drivers of outcome improvement.
The study uses a survey design in 40 heart transplant centres covering 11 countries in four continents.
Theoretical frameworks informed variable selection, which are measured by established and investigator-developed instruments. Heart transplant recipients, outpatient clinicians and programme's directors complete a survey. A staged convenience sampling strategy is implemented in heart transplant centres, countries and continents. Depending on the centre's size, a random sample of 25-60 patients is selected (N estimated 1680 heart transplant recipients). Five randomly selected clinicians and the medical director from each centre will be invited to participate.
This is the first multi-centre, multi-continental study examining healthcare system and heart transplant centres chronic illness management practice patterns and potential correlates of immunosuppressive medication non-adherence. The knowledge gained will inform clinicians, researchers and healthcare policy makers at which level(s) interventions need to be implemented to improve long-term outcomes for transplant recipients.
本文描述了“构建研究倡议小组:移植中的慢性病管理与依从性”(BRIGHT)研究的基本原理、设计和方法。这项针对心脏移植患者的研究将:(1)描述与慢性病管理相关的实践模式;(2)评估治疗方案不依从的患病率和变异性;(3)确定与免疫抑制药物不依从相关的多层次因素。
心脏移植后长期预后未改变,凸显了识别和改善与生存结果相关因素的迫切需求。医疗保健系统(如实施的慢性病管理水平)和患者自我管理是改善结果的主要驱动因素。
该研究采用调查设计,涉及四大洲11个国家的40个心脏移植中心。
理论框架为变量选择提供依据,这些变量通过既定的和研究人员开发的工具进行测量。心脏移植受者、门诊临床医生和项目主任完成一项调查。在心脏移植中心、国家和各大洲实施分阶段便利抽样策略。根据中心规模,随机抽取25 - 60名患者(估计N为1680名心脏移植受者)。将邀请每个中心随机选择的五名临床医生和医学主任参与。
这是第一项多中心、跨大洲的研究,旨在考察医疗保健系统和心脏移植中心的慢性病管理实践模式以及免疫抑制药物不依从的潜在相关因素。所获得的知识将为临床医生、研究人员和医疗保健政策制定者提供信息,告知他们需要在哪些层面实施干预措施以改善移植受者的长期预后。
