The aim of the study was to assess Type 1 (insulin-dependent) diabetic patients' ability to give valid information of the dietary carbohydrate (CHO) intake and to use the log function of a blood glucose meter for easy transfer of data to a decision support system. 18 Type 1 diabetic patients were enrolled from the Diabetes Outpatient Clinic at the Department of Endocrinology, Aalborg Hospital, Denmark. The patients were divided in subgroups of 4 or 5 patients and was instructed by the dietitian how to estimate the CHO intake and by the doctor in the use of the Accutrend DM blood glucose meter. During a 3 days data collecting period the patients were asked to keep a written diary containing a description of the meals, the estimated CHO intake, the insulin-dosage and the time of the meals and insulin injections, and to make 8-point blood glucose profiles daily. They were furthermore asked to use the log function of the Accutrend DM blood glucose meter. At the second visit the data were discussed individually with the patients and if there where more than three data points missing using the log function the patients were asked to repeat the data collection. A deviation of 10 grams or more, between the patient's and the dietician's estimate, was seen in 7.3% of the meals following the first instruction, in 1.0% of the meals following the second instruction, and in 2.4% of the meals following the third and last instruction. In conclusion, this study showed that Danish Type 1 diabetic patients were able to estimate the dietary carbohydrate content with a high degree of correctness, and to use the log function of the blood glucose meter, after a maximum of 3 hours of training.
该研究的目的是评估1型（胰岛素依赖型）糖尿病患者提供饮食碳水化合物（CHO）摄入量有效信息的能力，以及使用血糖仪的日志功能以便将数据轻松传输到决策支持系统的能力。18名1型糖尿病患者从丹麦奥尔堡医院内分泌科糖尿病门诊招募。患者被分成4或5人的小组，由营养师指导如何估算CHO摄入量，并由医生指导如何使用Accutrend DM血糖仪。在3天的数据收集期内，要求患者保留一份书面日记，记录饮食描述、估算的CHO摄入量、胰岛素剂量以及用餐和注射胰岛素的时间，并每天绘制8点血糖曲线。此外，要求他们使用Accutrend DM血糖仪的日志功能。在第二次就诊时，与患者单独讨论数据，如果使用日志功能缺失的数据点超过三个，则要求患者重复数据收集。在第一次指导后的餐食中，7.3%的餐食患者与营养师的估算偏差为10克或更多；在第二次指导后的餐食中，这一比例为1.0%；在第三次也是最后一次指导后的餐食中，这一比例为2.4%。总之，这项研究表明，丹麦1型糖尿病患者在最多3小时的培训后，能够高度准确地估算饮食碳水化合物含量，并使用血糖仪的日志功能。
