The management approach to non-insulin-dependent diabetes mellitus among fa
mily doctors in Hong Kong was studied using two case histories. In 1996, al
l 804 fellows, members and associate members of the Hong Kong College of Fa
mily Physicians were sent a letter and a questionnaire. Of the 512 who resp
onded, 405 were male and 95 were female (12 were discarded) with ages rangi
ng from 24 to 77 years (median 40). For the 48-year-old obese man who showe
d improvements in blood glucose and symptoms after diet for 6 weeks (Case 1
), most respondents suggested adding a sulphonylurea (39.0%) or metformin (
21.1%), or continuing diet (35.2%). Younger and more junior doctors tended
to use metformin plus diet. Of 192 respondents who wanted to use a sulphony
lurea, gliclazide (45.8%) and glibenclamide (42.7%) were chosen most often.
For the 76-year-old overweight woman with symptomatic diabetes despite die
t therapy (Case 2), most respondents suggested adding a sulphonylurea (41.9
%), metformin (25.6%) or both (19.2%). Younger and more junior doctors tend
ed to use metformin plus diet, whereas older doctors tended to use insulin
plus diet. Older and more experienced doctors tended to use diet plus metfo
rmin and sulphonylurea. Of 208 respondents who wanted to use a sulphonylure
a, gliclazide (47.8%) and glibenclamide (30.1%) were chosen most often. The
management approach to NIDDM varied with the age and experience of the doc
tor.
