BACKGROUND While the patient and public involvement (PPI) evidence base has expanded over the past decade, the quality of reporting within papers is often inconsistent, limiting our understanding of how it works, in what context, for whom, and why. OBJECTIVE To develop international consensus on the key items to report to enhance the quality, transparency, and consistency of the PPI evidence base. To collaboratively involve patients as research partners at all stages in the development of GRIPP2. METHODS The EQUATOR method for developing reporting guidelines was used. The original GRIPP (Guidance for Reporting Involvement of Patients and the Public) checklist was revised, based on updated systematic review evidence. A three round Delphi survey was used to develop consensus on items to be included in the guideline. A subsequent face-to-face meeting produced agreement on items not reaching consensus during the Delphi process. RESULTS One hundred forty-three participants agreed to participate in round one, with an 86% (123/143) response for round two and a 78% (112/143) response for round three. The Delphi survey identified the need for long form (LF) and short form (SF) versions. GRIPP2-LF includes 34 items on aims, definitions, concepts and theory, methods, stages and nature of involvement, context, capture or measurement of impact, outcomes, economic assessment, and reflections and is suitable for studies where the main focus is PPI. GRIPP2-SF includes five items on aims, methods, results, outcomes, and critical perspective and is suitable for studies where PPI is a secondary focus. CONCLUSIONS GRIPP2-LF and GRIPP2-SF represent the first international evidence based, consensus informed guidance for reporting patient and public involvement in research. Both versions of GRIPP2 aim to improve the quality, transparency, and consistency of the international PPI evidence base, to ensure PPI practice is based on the best evidence.

GRIPP2 报告清单：改善患者和公众参与研究报告的工具。

背景虽然患者和公众参与（PPI）的证据基础在过去十年中不断扩大，但论文中的报告质量往往不一致，限制了我们对其如何运作、在什么背景下、为谁运作以及为何运作的理解。目标 就报告的关键项目达成国际共识，以提高 PPI 证据基础的质量、透明度和一致性。让患者作为研究伙伴参与 GRIPP2 开发的各个阶段。方法 使用 EQUATOR 方法来制定报告指南。根据更新的系统审查证据，对最初的 GRIPP（患者和公众参与报告指南）清单进行了修订。使用三轮德尔菲调查就指南中包含的项目达成共识。随后举行的面对面会议就德尔菲流程中未达成共识的项目达成了一致。结果 143 名参与者同意参加第一轮，第二轮的响应率为 86% (123/143)，第三轮的响应率为 78% (112/143)。德尔福调查确定了对长格式 (LF) 和短格式 (SF) 版本的需求。GRIPP2-LF 包括 34 个项目，涉及目标、定义、概念和理论、方法、参与阶段和性质、背景、影响的捕捉或测量、结果、经济评估和反思，适合以 PPI 为主要重点的研究。GRIPP2-SF 包括关于目标、方法、结果、结果和批判视角的五个项目，适合以 PPI 为次要焦点的研究。结论 GRIPP2-LF 和 GRIPP2-SF 代表了第一个基于国际证据、共识的指南，用于报告患者和公众参与研究。GRIPP2 的两个版本都旨在提高国际 PPI 证据库的质量、透明度和一致性，以确保 PPI 实践基于最佳证据。为了鼓励其广泛传播，本文可在 BMJ 和 Research Involvement and Engagement 期刊网站上免费获取。
