BACKGROUND Poor agreement among lung transplant (LTx) pathologists has been reported in the assessment of rejection. In addition to acute rejection (AR) and lymphocytic bronchiolitis (LB), acute lung injury (ALI) and organizing pneumonia (OP) were recently identified as histopathologic risk factors for chronic lung allograft dysfunction (CLAD). Therefore, maximizing inter-rater reliability (IRR) for identifying these histopathologic risk factors is important to guide individual patient care and to support incorporating them in inclusion criteria for clinical trials in lung transplantation. METHODS Nine pathologists across 8 North American LTx centers were surveyed for practices in the assessment of LTx transbronchial biopsies. We conducted 7 diagnostic alignment sessions with pathologists discussing histomorphologic features of CLAD high-risk histopathology. Then, each pathologist blindly scored 75 digitized slides. Fleiss' kappa, accounting for agreement across numerous observers, was used to determine IRR across all raters for the presence of any high-risk finding and each individual entity. RESULTS IRR (95% confidence intervals) and % agreement for any high-risk finding (AR, LB, ALI, and/or OP) and each individual finding is as follows: Any Finding, k = 0.578 (0.487, 0.668), 78.9%; AR, k = 0.582 (0.481, 0.651), 79.1%; LB, k = 0.683 (0.585, 0.764), 83.5%; ALI, k = 0.418 (0.312, 0.494), 70.9%; and OP, k = 0.621 (0.560, 0.714), 81.0%. CONCLUSIONS After prestudy diagnostic alignment sessions, a multicenter group of LTx pathologists seeking to identify histopathology high-risk for CLAD achieved good IRR.

诊断对齐以优化肺移植病理学家的评分者间可靠性。



背景 据报道,肺移植 (LTx) 病理学家在排斥反应评估中的一致性不佳。除了急性排斥反应 (AR) 和淋巴细胞性细支气管炎 (LB) 外,急性肺损伤 (ALI) 和机化性肺炎 (OP) 最近被确定为慢性肺同种异体移植物功能障碍 (CLAD) 的组织病理学危险因素。因此,最大限度地提高评分者间可靠性 (IRR) 以识别这些组织病理学风险因素对于指导个体患者护理并支持将其纳入肺移植临床试验的纳入标准非常重要。方法 对 8 个北美 LTx 中心的 9 名病理学家进行了 LTx 经支气管活检评估实践的调查。我们与病理学家进行了 7 次诊断对齐会议,讨论 CLAD 高危组织病理学的组织形态学特征。然后,每位病理学家盲目地对 75 张数字化载玻片进行评分。Fleiss 的 kappa 考虑了众多观察者的一致性,用于确定所有评分者是否存在任何高风险发现和每个个体实体的 IRR。结果 IRR(95% 置信区间)和任何高风险发现(AR、LB、ALI 和/或 OP)和每个单独发现的一致性百分比如下:任何发现,k = 0.578(0.487、0.668),78.9%;AR, k = 0.582 (0.481, 0.651), 79.1%;LB, k = 0.683 (0.585, 0.764), 83.5%;ALI, k = 0.418 (0.312, 0.494), 70.9%;OP,k = 0.621 (0.560, 0.714),81.0%。结论 在研究前诊断对齐会议后,一个多中心组 LTx 病理学家寻求确定 CLAD 的高危组织病理学取得了良好的 IRR。
