Uncontrolled hyperglycemia in hospitalized patients, with or without diabetes mellitus, is associated with many adverse outcomes. Resident physicians are the primary managers of inpatient glycemic control (IGC) in many academic and community medical centers; however, no validated survey tools related to their perceptions and knowledge of IGC are currently available. As identification of common barriers to successful IGC amongst resident physicians may help foster better educational interventions (ultimately leading to improvements in IGC and patient care), we sought to construct and preliminarily evaluate such a survey tool.
We developed the IGC questionnaire (IGCQ) by using previously published but unvalidated survey tools related to physician perspectives on inpatient glycemic control as a framework. We administered the IGCQ to a cohort of resident physicians from the University of Mississippi Medical Center, University of Louisville, Emory University, and the University of Virginia. We then used classical test theory and Rasch Partial Credit Model analyses to preliminarily evaluate and revise the IGCQ. The final survey tool contains 16 total items and three answer-choice categories for most items.
Two hundred forty-six of 438 (56.2%) eligible resident physicians completed the IGCQ during various phases of development.
We constructed and preliminarily evaluated the IGCQ, a survey tool that may be useful for future research into resident physician perceptions and knowledge of IGC. Future studies could seek to externally validate the IGCQ and then utilize the survey tool in pre- and post-intervention assessments.
住院患者（无论是否患有糖尿病）的血糖控制不佳与许多不良结局有关。住院医师是许多学术和社区医疗中心住院患者血糖控制（IGC）的主要管理者；然而，目前尚无与他们对 IGC 的看法和知识相关的经过验证的调查工具。由于确定住院医师在成功进行 IGC 方面的常见障碍可能有助于促进更好的教育干预措施（最终导致 IGC 和患者护理的改善），因此我们试图构建和初步评估此类调查工具。
我们使用先前发表但未经验证的与医师对住院患者血糖控制的看法相关的调查工具作为框架，制定了 IGC 问卷（IGCQ）。我们向密西西比大学医学中心、路易斯维尔大学、埃默里大学和弗吉尼亚大学的住院医师队列发放了 IGCQ。然后，我们使用经典测试理论和 Rasch 部分信用模型分析对 IGCQ 进行初步评估和修订。最终的调查工具包含 16 个总项目和大多数项目的三个答案选择类别。
在不同的开发阶段，有 246 名符合条件的住院医师（56.2%）完成了 IGCQ。
我们构建并初步评估了 IGCQ，这是一种可能对未来研究住院医师对 IGC 的看法和知识有用的调查工具。未来的研究可以寻求对外验证 IGCQ，然后在干预前后评估中使用该调查工具。
