To investigate the agreement between self-report and a public registry regarding the occurrence and duration of sickness absence (SA) in patients with sciatica.
Observational 2-year longitudinal study including 227 patients. Self-report SA data were obtained by postal questionnaires covering recall periods of 3, 6, and 12 months and compared with data from the Norwegian National Sickness Benefit Register.
The percent agreement on the occurrence of SA between self-report and registry was above 85% for all three recall periods. The patients overestimated the duration of their SA by 2.4 (95% confidence interval, 1.1-3.7) weeks for the 3-month recall period. The 95% limits of agreement were generally wide, varying from -12.5 to 17.3 weeks for the 3-month recall period to -38.8 to 37.2 weeks for the 12-month period. For the 3-, 6-, and 12-month recall periods, 48.1%, 29.8%, and 27.3% of the patients reported an SA duration that differed by ≤1 week from that recorded in the registry.
Mainly because of low precision, the agreement on the duration of SA was poor for all three recall periods. The agreement between self-report and registry regarding the occurrence of SA was good.
调查在坐骨神经痛患者中，自我报告和公共登记处关于缺勤（SA）发生和持续时间的一致性。
包括 227 名患者的观察性 2 年纵向研究。通过涵盖 3、6 和 12 个月的回顾期的邮政问卷获得自我报告的 SA 数据，并与挪威国家病假津贴登记处的数据进行比较。
在所有三个回顾期，自我报告和登记处关于 SA 发生的百分比一致性均高于 85%。患者对其 SA 持续时间的估计平均高估了 2.4 周（95%置信区间，1.1-3.7）。95%的一致性界限通常很宽，从 3 个月回顾期的-12.5 到 17.3 周不等，到 12 个月的-38.8 到 37.2 周不等。在 3、6 和 12 个月的回顾期，48.1%、29.8%和 27.3%的患者报告 SA 持续时间与登记处记录的相差不超过 1 周。
由于精度低，所有三个回顾期的 SA 持续时间的一致性都很差。自我报告和登记处关于 SA 发生的一致性良好。
