回忆患者报告的结果的可靠性，如健康相关的生活质量，满意度和症状，差异很大。这份特别报告的目的是确定研究设计中需要考虑的关键问题，并为最大限度地减少研究中的偏倚（包括患者报告的结局）提供建议。MEDLINE检索确定了患者回忆存在偏倚的几个领域。患者回忆与基线评估之间的一致性（例如，在事件或医疗干预之前），这些患者报告的结局根据召回的事件、事件发生后的时间以及患者临床和人口统计学特征而变化。症状回忆往往比健康相关的生活质量或疼痛强度的回忆更好。具体的问卷调查技术可能有助于最大限度地减少回忆偏差的影响。需要进一步的研究来确定哪些因素或患者特征可以预测回忆的改善，以及哪些技术可以最大限度地减少回忆偏差。
The reliability of recall patient reported outcomes, such as health-related quality of life, satisfaction and symptoms, varies substantially. The objectives of this special report are to identify key issues to consider in study design and provide suggestions for minimizing bias in studies including patient reported outcomes. A MEDLINE search identified several areas in which patient recall is subject to bias. Concordance between patient recall and baseline assessments (e.g., prior to an event or medical intervention) for these patient reported outcomes varies depending on the event being recalled, time since the event, and patient clinical and demographic characteristics. Symptom recall tends to be better than recall of health-related quality of life or pain intensity. Specific questionnaire techniques may help minimize the impact of recall bias. Further research is required to determine what factors or patient characteristics predict improved recall and what techniques minimize recall bias.
