Recall of severe hypoglycaemia and self‐estimated state of awareness in type 1 diabetes
Abstract
Background The ability of people with insulin-treated diabetes to remember severe hypoglycaemia and the consistency of their self-estimated awareness of hypoglycaemia are not well documented but are important in clinical practice. The aim of this study is to assess recall of severe hypoglycaemia in patients with type 1 diabetes and to evaluate the feasibility of a simple method for clinical classification of the awareness of hypoglycaemia. Methods A one-year prospective study was performed on a cohort of patients with type 1 diabetes (n = 230). The rate of severe hypoglycaemia reported retrospectively at the end of the study was compared to the prospectively recorded rate during the study period. Self-estimated awareness was explored in questionnaires at baseline and at the end, and assessments were evaluated by the occurrence of severe hypoglycaemic episodes. Results Almost 90% of the participants correctly recalled whether they had had severe hypoglycaemia. However, those with high prospectively recorded numbers had incomplete recall, resulting in a 15% underestimation of the overall rate. On the basis of the answer to the question "Do you recognise symptoms when you have a hypo?", the population was classified into three groups: 40% with normal awareness, 47% with impaired awareness and 13% with unawareness. The groups with impaired awareness and unawareness had 5.1 and 9.6 times higher rates of severe hypoglycaemia, respectively, compared to the group with normal awarenes…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
