To assess differences between estimated blood glucose values and those measured on a blood glucose meter and the impact on self-care behavior in type 2 diabetes.
Subjects ≥18 years with type 2 diabetes (N = 297) attending a Taking Control of Your Diabetes conference were asked questions about diabetes management and to estimate their current blood glucose. Study staff tested subjects' blood glucose on a meter. After seeing the result, subjects were again asked questions on diabetes management.
NCT01453413.
The percentage of subject blood glucose estimations that were outside ISO 15197:2003 accuracy criteria (>±15 mg/dL or >±20% of meter glucose values).
Nearly half (46%) of subjects estimated blood glucose values outside ISO 15197:2003 accuracy criteria. Time since last blood glucose test, time since last meal, testing frequency, and A1C did not have an effect on differences between estimated blood glucose values and meter results. In the questionnaire before blood glucose testing, most subjects strongly agreed, agreed, or neither agreed nor disagreed that 'I make decisions about my diabetes, such as my food intake or my insulin dose even when I do not test my blood sugar' (71%) and 'My body tells me without testing if my blood sugar is low or high' (77%). After blood glucose testing, 99% of subjects strongly agreed, agreed, or neither agreed nor disagreed that 'Knowing my blood sugar by checking could help me make different diabetes decisions'.
Self-monitoring of blood glucose is an important component of diabetes self-management. Testing rather than guessing blood glucose values is important to obtain accurate results and inform people with type 2 diabetes to make effective, appropriate diabetes management decisions. A potential limitation of this study is that the subject population may not be representative of the general population of people with diabetes; however, the conference setting may attract a more motivated population, which could underestimate the magnitude of the results.
评估估算血糖值与血糖仪测量值之间的差异，以及对2型糖尿病患者自我护理行为的影响。
参加“掌控你的糖尿病”会议的≥18岁2型糖尿病患者（N = 297）被问及有关糖尿病管理的问题，并要求估算他们当前的血糖水平。研究人员用血糖仪检测受试者的血糖。在看到结果后，再次询问受试者有关糖尿病管理的问题。
NCT01453413。
受试者血糖估算值超出ISO 15197:2003准确性标准（>±15 mg/dL或>血糖仪血糖值的±20%）的百分比。
近一半（46%）的受试者估算的血糖值超出ISO 15197:2003准确性标准。距上次血糖检测的时间、距上次进餐的时间、检测频率和糖化血红蛋白对估算血糖值与血糖仪测量结果之间的差异没有影响。在血糖检测前的问卷中，大多数受试者强烈同意、同意或既不同意也不反对“即使我不检测血糖，我也会对自己的糖尿病做出决定，比如我的食物摄入量或胰岛素剂量”（71%）以及“即使不检测，我的身体也会告诉我血糖是低还是高”（77%）。血糖检测后，99%的受试者强烈同意、同意或既不同意也不反对“通过检测了解我的血糖有助于我做出不同的糖尿病决策”。
血糖自我监测是糖尿病自我管理的重要组成部分。检测血糖而非猜测血糖值对于获得准确结果以及告知2型糖尿病患者做出有效、恰当的糖尿病管理决策很重要。本研究的一个潜在局限性是受试者群体可能不代表糖尿病患者的总体人群；然而，会议环境可能吸引了积极性更高的人群，这可能会低估结果的严重程度。
