基于患者报告的复发 (复发复发;ROR) 的柱状鼻疾病研究可能低估了疾病发生率. 结构化的后续对减轻观察偏差和确保准确的外科结果报告至关重要.
科学领域:
- 手术成果研究的研究结果.
- 医学偏见分析 医学偏见分析
- 支柱状鼻疾病管理
背景情况:
- 柱状鼻疾病 (PSD) 研究往往缺乏标准化的随访,可能导致观察偏差.
- "复发回报" (ROR) 后续方法对PSD中报告的复发率的影响尚不清楚.
- 这项研究假设,与结构化随访协议相比,ROR方法显著低于报告疾病复发率.
研究的目的:
- 调查和量化pilonidal鼻疾病研究中的观察偏差.
- 为了比较定期随访与ROR随访的研究之间的复发率.
- 评估后续方法对PSD手术结果数据有效性的影响.
主要方法:
- 在1833年至2023年期间发表的1,222项柱状鼻疾病研究 (135,349名患者) 的系统综述和元分析.
- 研究被分类为随机对照试验 (RCT),ROR试验和非RCT非ROR (N) 试验.
- 对不同后续方法的五年和十年复发率的比较分析.
主要成果:
- 五年复发率:RCT (18.9%),N试验 (10.4%),ROR试验 (12.4%).这些试验的复发率大约是5年.
- 在十年的随访中,RCT显示的复发率明显高于N或ROR试验 (p<0.001).
- 对于初级开放治疗,五年复发率各不相同:RCT (18.6%),N试验 (11.5%),ROR试验 (4.1%),其中ROR可能显著低估了几率.
结论:
- 观测偏差在pilonidal鼻疾病中的ROR研究结果上产生了重大影响.
- 结构良好的,基于间隔的患者随访对于减轻偏差和提高PSD研究结果的有效性至关重要.
- ROR研究可能会报告复发率比RCT或非RCT低三到四倍,突出需要标准化后续方案.
