背景-在加拿大安大略省，门诊心血管健康研究小组(CANHEART)正在进行一项独特的、以人群为基础的观察性研究计划，旨在衡量和改善心血管健康和门诊心血管护理的质量。一个特别的重点将是确定在安大略省多样化的多种族人口中改善心血管事件的一级和二级预防的机会。方法和结果-2008年，通过使用编码的个人识别器连接多个电子调查、健康管理、临床、实验室、药物和电子病历数据库，建立了一个包括980万安大略省成年人的基于人群的队列。该队列包括大约940万一级预防患者和大约40万二级预防患者。对临床事件的跟踪是通过与综合住院、急诊科和生命统计管理数据库的记录链接实现的。将在健康地区层面建立心血管健康和预防保健概况，并将利用队列研究重大心血管事件发生率的地区差异原因和其他重要研究问题。结论-多个数据库的链接将使CANHEART研究队列成为旨在改善心血管健康和卫生服务提供的科学研究的强大大数据资源。研究结果将与临床医生、政策制定者和公众分享，以促进人口健康干预和质量改进倡议。
Background-The CArdiovascular HEalth in Ambulatory care Research Team (CANHEART) is conducting a unique, population-based observational research initiative aimed at measuring and improving cardiovascular health and the quality of ambulatory cardiovascular care provided in Ontario, Canada. A particular focus will be on identifying opportunities to improve the primary and secondary prevention of cardiovascular events in Ontario's diverse multiethnic population.Methods and Results-A population-based cohort comprising 9.8 million Ontario adults >= 20 years in 2008 was assembled by linking multiple electronic survey, health administrative, clinical, laboratory, drug, and electronic medical record databases using encoded personal identifiers. The cohort includes approximate to 9.4 million primary prevention patients and approximate to 400 000 secondary prevention patients. Follow-up on clinical events is achieved through record linkage to comprehensive hospitalization, emergency department, and vital statistics administrative databases. Profiles of cardiovascular health and preventive care will be developed at the health region level, and the cohort will be used to study the causes of regional variation in the incidence of major cardiovascular events and other important research questions.Conclusions-Linkage of multiple databases will enable the CANHEART study cohort to serve as a powerful big data resource for scientific research aimed at improving cardiovascular health and health services delivery. Study findings will be shared with clinicians, policy makers, and the public to facilitate population health interventions and quality improvement initiatives.
