概括

一个预测模型确定了在患有糖尿病风险的急诊室患者中血红蛋白A1c (HbA1c) 升高的关键因素. 药物滥用成为一个重要的预测因素,影响后续护理策略.

科学领域:

糖尿病研究研究糖尿病研究
在医疗保健中的预测建模.
紧急医疗紧急医疗

背景情况:

血红蛋白A1c (HbA1c) 升高表明血糖控制不佳,这是糖尿病的危险因素.
在急诊室 (ED) 识别患有HbA1c升高的个体对于及时干预至关重要.
预测模型可以帮助分层风险,并指导风险人群的后续护理.

研究的目的:

开发和验证一个预测模型,用于高HbA1c (≥5.7%) 在诊断糖尿病的急诊室患者.
确定与HbA1c升高相关的主要人口,临床和历史因素.
为在ED环境中确定患有糖尿病前期或糖尿病的患者提供后续护理策略的信息.

主要方法:

追溯分析ED中查糖尿病的590名患者的电子健康记录.
使用推导集 (80%) 开发预测模型,并进行向后消除和交叉验证.
在单独的测试组 (20%) 上验证模型,并使用C统计,灵敏度,特异性和Brier分数进行性能评估.

主要成果:

最终的预测模型包含了九个变量:年龄,种族/种族,保险,主要投诉 (背痛,发烧/),以及病史 (肥胖,高脂血症,慢性肺炎,滥用药物).
该模型表现出可接受的性能,C统计值为0.75,预测值超过0.70.
霍斯默-莱梅肖测试 (0.29) 和布里尔得分 (0.21) 表示没有显著的模型不适合和中等的预测准确性.

结论:

年龄,肥胖,高脂血症,以及重要的是,滥用药物的病史,是ED患者HbA1c升高的显著预测因素.
在规划对被确诊患有糖尿病前期或糖尿病在ED的个人进行后续护理时,应考虑滥用药物.
需要进一步的研究,包括在更大的ED人群中进行外部验证,以证实这些发现.

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
