成人斜视患者报告结局测评系统的构建及应用

目的基于计算机自适应测试技术构建成人斜视患者报告结局测评系统,并评价临床应用效果。方法以患者报告结局国际开发标准作为方法学指南,采用质性研究、德尔菲法、Rasch模型等方法形成测评条目,基于计算机自适应测试技术建立测试系统,包括测评系统、统计相关和系统管理3大核心模块。将该系统应用于101例成人斜视患者(系统测评组),并与采用纸质版测评的对照组(100例)进行效果比较。结果系统测评组测评时间显著短于对照组,患者测评满意率及依从率显著高于对照组(P<0.05,P<0.01)。结论基于计算机自适应测试技术开发的成人斜视患者报告结局测评系统,可缩短测评时间,提高患者测评满意度和依从性。

Design and application of patientreported outcome information system for adult strabismus based on computer adaptive testing

Objective To develop patient-reported outcome (PRO)information system for adult strabismus based on computer adapttve testing (CAT),and to evaluate its application effect.Methods Following the guidance that was approved by the U.S.Food and Drug Administration for developing PRO instrument,we employed qualitative research,Delphi process and the Rasch model to establish the item pool,then we used CAT to create the information system which included three core modules as assessment,statistics,and system management.A total of 101 adults with strabismus were assessed by the information system (the system group) and effect was compared with 100 controls who were assessed using paper sheets (the control group).Results The system group used shorter time to assess,and had higher patient satisfaction and compliance with the assessment (P<0.05 ,P<0.01).Conclusion The CAT-assisted PRO information system can reduce assessment time and improve patient satisfaction and compliance.
