研究目的:

在本回顾性队列研究中,通过收集2型糖尿病住院患者的电子病历数据,建立了基于机器学习算法的DR发生风险的预测模型。并探讨可能影响糖尿病视网膜病变发生的危险因素,希望为临床上糖尿病视网膜病变的预防和管理提供依据。  

Objectives of Study:

In this retrospective cohort study, we collected electronic health record data from hospitalized patients with type 2 diabetes, established the prediction model for future risks of DR based on machine learning (ML) algorithm. We also explore the risk factors that may affect the occurrence of DR and hope this work can provide a basis for further studies concerning with prevention and management of DR.

纳入标准:

在本回顾性队列研究中,我们招募了2010年1月至2020年1月大连医科大学附属大连中心医院内分泌科住院患者。本研究纳入符合以下标准的患者:1)年龄≥18岁,诊断为2型糖尿病;2)随访期间至少住院一次。3)首次住院时未诊断为糖尿病视网膜病变。

Inclusion criteria

In this retrospective cohort study, we recruited inpatients admitted to the Department of endocrinology of Dalian Medical University Affiliated the Central Hospital of Dalian from January 2010 to January 2020. Patients who met the following criteria were included in the current study: 1) Age≥18 years with the diagnosis of type 2 diabetes; 2) Be hospitalized at least once over the follow-up period. 3) No presence of diabetic retinopathy at the time of the first hospitalization.

排除标准:

其他类型糖尿病患者(1型糖尿病、特殊型糖尿病或妊娠期糖尿病);或既往眼疾(白内障、青光眼或其他眼疾)。

Exclusion criteria:

Patients with other types of diabetes (type 1, specific type or gestational diabetes); Or pre-existing eye disease (cataract, glaucoma, or other eye disease).
