Assessment of hypoglycaemia and severe hypoglycaemia
Of a total of 131 subjects, 22.5% had reported at least 1 episode of severe hypoglycaemia over the last one year. The prevalence of severe hypoglycaemia over the last one year in subjects with Clarke score =< 3 and >= 4 was 19.8% and 41.4% respectively, while in subjects with Gold score =< 3 and >= 4, the prevalence was 22.4% and 32.4% respectively. 19.1% had ever been previously hospitalized or attended emergency department for hypoglycaemia.
Eighty subjects (61.1%) submitted SMBG records, of whom 53.8% (43 subjects) had performed at least 3 blood glucose tests daily. During the 4-week period of SMBG, the mean number of blood glucose readings per day was 3.1, while the mean blood glucose was 9.6 mmol/L. Of the 80 subjects who submitted SMBG records, 38.8% had at least 1 episode of clinically significant hypoglycaemia (blood glucose < 3 mmol/L) during the prospective 4 week period of SMBG.
