目的：调查口服药治疗中的2型糖尿病患者对胰岛素的认知状况。方法择期手术的糖尿病患者230人，通过问卷确定胰岛素认知偏差组124人；认知相对客观的对照组106人。结果偏差组占54%，其中的女性、高龄、低教育程度和居住在农村的比例高于对照组，曾经应用过胰岛素的比例低于对照组。偏差组的平均糖化血红蛋白高于对照组，术前血糖准备时间长于对照组，发生低血糖比例的差异无统计学意义。结论口服药物治疗中的糖尿病患者仍有54%的人存在胰岛素认知偏差；他们的血糖控制较差，术前血糖准备的时间较长。%Objective To investigate the insulin cognition of patients with type 2 diabetes mellitus (T2DM) waiting for selective operations. Methods A total of 230 inpatients with type 2 diabetes mellitus were investigated, including 124 patients with improper insulin cognition (Group Improper Cognition, GIC) and 106 patients with proper insulin cognition (Group Proper Cognition, GPC) as control. Results 54%inpatients with type 2 diabetes mellitus treated with oral antidiabetic drugs (OAD) had improper insulin cognition. GIC had higher HbA1c%(8.26±1.56 vs 7.68±1.55, P=0.005), more time of preoperative preparation [(4.74±1.29) days vs (3.87±1.25) days, P=0.000], higher proportions of female [(85/124) vs (57/106), P=0.031], aged patients [(70/124) vs (45/106), P=0.047], lower educational level [(41/124) vs (20/106), P=0.023], rural inhabitant [(55/124) vs (31/106), P=0.026] and less previous insulin application [(21/124) vs (36/106), P=0.005] than those of GPC. T2DM family history [(31/124) vs (34/106), P=0.298] and hypoglycemia occurrence [(18/124) vs (7/106), P=0.087] were not statistically significant between the two groups. Conclusions There were still 54%inpatients with type 2 diabetes mellitus treated with OAD having improper insulin cognition. They were of bad blood glucose control and needed more time to control blood glucose treated with insulin for preoperative preparation.
