Bound by a shared commitment to improving medical care through systematic inquiry, practice-based research networks (PBRNs) provide a basic laboratory for primary care research and dissemination.
Data from US primary care PBRNs were collected as part of the 2011 Agency for Healthcare Research and Quality PBRN registration process. Data addressed PBRN characteristics, research activities, and perceived strengths and weaknesses.
One hundred forty-three primary care PBRNs were registered with the resource center in 2011, including 131 that were identified as either eligible for Agency for Healthcare Research and Quality recognition (n = 121) or as developing (n = 10). These PBRNs included 12,981 practices with more than 63,000 individual members providing care to approximately 47.5 million people. PBRNs had an average of 482 individual members (median, 170) from 101 practices (median, 32).
PBRNs are growing in experience and research capacity. With member practices serving approximately 15% of the US population, PBRNs are adopting more advanced study designs, disseminating and implementing practice change, and participating in clinical trials. PBRNs provide valuable capacity for investigating questions of importance to clinical practice, disseminating results, and implementing evidence-based strategies. PBRNs are well positioned to support the emerging public health role of primary care providers and provide an essential component of a learning health care system.
基于通过系统探究改善医疗的共同承诺，以实践为基础的研究网络（PBRNs）为初级保健研究和传播提供了基本的实验室。
作为美国医疗保健研究和质量机构（AHRQ）2011 年实践研究网络注册流程的一部分，收集了美国初级保健 PBRNs 的数据。这些数据涉及 PBRN 的特征、研究活动以及感知到的优势和劣势。
2011 年，有 143 个初级保健 PBRNs 在资源中心注册，其中 131 个被确定为有资格获得 AHRQ 认可（n=121）或正在发展中（n=10）。这些 PBRNs 包括 12981 个实践，有超过 63000 名个体成员为大约 4750 万人提供医疗服务。PBRNs 的平均成员人数为 482 人（中位数为 170），来自 101 个实践（中位数为 32）。
PBRNs 在经验和研究能力方面不断发展。随着成员实践服务于大约 15%的美国人口，PBRNs 正在采用更先进的研究设计，传播和实施实践变革，并参与临床试验。PBRNs 为调查对临床实践重要的问题、传播结果和实施基于证据的策略提供了宝贵的能力。PBRNs 非常适合支持初级保健提供者新出现的公共卫生角色，并为学习型医疗保健系统提供重要组成部分。
