背景：国际健康结果测量联合会（ICHOM）最近就腭裂护理综合评估的核心结果集达成一致，该结果集更加强调患者报告的结果测量（PROMS），特别是cleft - q。CLEFT-Q包括12个量表，总共110个题目，旨在让8岁的孩子回答。目的：在本研究中，我们旨在使用计算机化自适应测试（CAT）来减少预测每个CLEFT-Q量表结果所需的项目数量。方法：我们使用一个开源的CAT模拟包，在每个全长量表及其CAT对应量表上以不同程度的精度运行项目反应，通过标准误差（SE）估计。为每个量表的CAT记录达到给定SE所需的平均项目数，并计算全长量表结果与CAT版本预测结果之间的相关性。结果：对12个CLEFT-Q量表中的每个量表使用CAT，我们减少了参与者需要回答的问题数量，即从110个减少到平均43.1个（范围34-60，SE < 0.55），同时保持CAT得分与全长量表之间97%的相关性。结论：CAT可能在临床实践中发挥了重要作用，因为它可以用更少的项目实现高度的准确性。(C) 2019年英国整形、重建和美容外科医生协会。Elsevier Ltd.出版。
Background: The International Consortium for Health Outcome Measurement (ICHOM) has recently agreed upon a core outcome set for the comprehensive appraisal of cleft care, which puts a greater emphasis on patient-reported outcome measures (PROMS) and, in particular, the CLEFT-Q. The CLEFT-Q comprises 12 scales with a total of 110 items, aimed to be answered by children as young as 8 years old.Objective: In this study, we aimed to use computerised adaptive testing (CAT) to reduce the number of items needed to predict results for each CLEFT-Q scale.Method: We used an open-source CAT simulation package to run item responses over each of the full-length scales and its CAT counterpart at varying degrees of precision, estimated by standard error (SE). The mean number of items needed to achieve a given SE was recorded for each scale's CAT, and the correlations between results from the full-length scales and those predicted by the CAT versions were calculated.Results: Using CATs for each of the 12 CLEFT-Q scales, we reduced the number of questions that participants needed to answer, that is, from 110 to a mean of 43.1 (range 34-60, SE < 0.55) while maintaining a 97% correlation between scores obtained with CAT and full-length scales.Conclusions: CAT is likely to play a fundamental role in the uptake of PROMs into clinical practice given the high degree of accuracy achievable with substantially fewer items.
