International GP consultation length data - 2017 review

We searched the following electronic databases from January 1946 to 2016: English language (Medline, Embase), Chinese (CNKI, Wanfang, VIP), Japanese (Ichushi), Russian (Yandex, Rambler), and Spanish and Portuguese (SciELO). The search strategy was based on the Medline search described by Wilson <em>et al</em> (excluding steps 24–34). Sample search strategy can be found in the full paper Searches were supplemented by a survey of national members from the World Organization of National Colleges, Academies and Academic Associations of General Practitioners/Family Physicians (WONCA), who were asked to search the grey literature in their respective country for evidence relating to consultation length in either English or their native language. The grey literature search also included the WHO/INRUD database (2000–2016) and Robert Graham data repository (2009–2016). One author (GI) screened all references and excluded duplicate records and those that were not eligible based on our selection criteria for considering studies. Two authors (GI and ALN) then applied the criteria to the short-listed references for full-text screening. We included observational studies including cross-sectional studies, surveys and cohorts of consultation length with primary care physicians. Primary care physicians were defined broadly as any medically qualified physician who provides primary care. Terms for primary care physicians differ according to different settings and include general practitioners (GPs), family doctors, family practitioners and other physicians working in primary healthcare settings and who perform primary healthcare task. Studies set in secondary care and randomised controlled trials were excluded.

本研究于1946年1月至2016年期间检索了以下电子数据库：英文数据库（Medline、Embase）、中文数据库（中国知网CNKI、万方数据、维普资讯VIP）、日文数据库（Ichushi）、俄文数据库（Yandex、Rambler），以及西班牙文与葡萄牙文数据库（SciELO）。检索策略基于Wilson等（省略第24-34步）所报道的Medline检索方案，示例检索策略详见全文。
本研究通过世界全科医师/家庭医师国家学院、学术机构及学术协会国际组织（World Organization of National Colleges, Academies and Academic Associations of General Practitioners/Family Physicians, WONCA）的成员国成员开展补充检索：邀请其以英文或本国语言，针对本国范围内与诊疗时长相关的证据进行灰色文献检索。本次灰色文献检索还涵盖了世界卫生组织/国际初级卫生保健研究与发展网络数据库（WHO/INRUD，2000-2016年）以及罗伯特·格雷厄姆数据仓储库（2009-2016年）。
一名作者（GI）对所有参考文献进行初筛，剔除重复记录以及不符合本研究纳入标准的文献。随后，两名作者（GI与ALN）针对初筛入选的参考文献开展全文复筛，严格应用本研究的纳入排除标准。
本研究纳入以初级保健医师为研究对象的诊疗时长相关观察性研究，包括横断面研究、调查研究及队列研究。初级保健医师的定义范畴较广，指所有具备行医资质并提供初级保健服务的医师。不同地区对初级保健医师的称谓存在差异，包括全科医生（general practitioners, GPs）、家庭医生、家庭医师，以及其他在初级医疗保健机构执业并承担初级保健工作的医师。本研究排除二级医疗机构开展的研究及随机对照试验。
