To investigate patients' views about their lowest tolerable blood glucose level and explore symptoms they may develop below that level.
A semi-structured patient interview.
Outpatient clinic for older people (≥75 years) with diabetes.
Patients attending an outpatient clinic over a six months period who are monitoring their blood glucose at home and able to participate in interview.
Sixty one patients gave answers to the interview questions. Mean (SD) age was 82.3 (3.9) years and 33 (54%) were females. All patients indicated that they were usually aware when hypoglycaemia occurs but the symptoms reported were mostly non specific. The threshold for hypoglycaemia was 5 mmol/L in 13 (21%) patients, 6 mmol/L in 14 (23%) patients, 7 mmol/L in 13 (21%) patients, 8 mmol/L in 17 (28%) patients and 9 mmol/L in 4 (7%) patients. There was no significant difference between patients who were symptomatic at a higher blood glucose level (>6 mmo/L) and those who developed symptoms at a lower level (≤6 mmol/L).
Older people with diabetes who seem to be aware of hypoglycaemia report mostly non specific symptoms. The threshold of experiencing hypoglycaemic symptoms appears to be higher than the usually defined <4 mmol/L.
调查患者对自身最低耐受血糖水平的看法，并探讨其血糖水平低于该值时可能出现的症状。
半结构式患者访谈。
老年（≥75 岁）糖尿病患者的门诊诊所。
在六个月期间监测自身血糖并能够接受访谈的门诊就诊患者。
61 名患者回答了访谈问题。平均（SD）年龄为 82.3（3.9）岁，33 名（54%）为女性。所有患者均表示，通常在发生低血糖时会有所察觉，但报告的症状大多是非特异性的。13 名（21%）患者的低血糖阈值为 5mmol/L，14 名（23%）患者为 6mmol/L，13 名（21%）患者为 7mmol/L，17 名（28%）患者为 8mmol/L，4 名（7%）患者为 9mmol/L。血糖水平较高（>6mmol/L）时出现症状的患者与血糖水平较低（≤6mmol/L）时出现症状的患者之间没有显著差异。
似乎意识到低血糖的老年糖尿病患者报告的症状大多是非特异性的。出现低血糖症状的阈值似乎高于通常定义的<4mmol/L。
