HK has a higher educational level overall. To summarize, probably the most important reasons for the relatively high rate of complications from DM is poor service aspects, particularly those relating to screening and follow-up. With change of policy, management of DM could improve coverage of complication-screening. Specialist centres are more likely to screen for complications than GPs, however, specialist units are no guarantee of continuity of care, good case notes or patient education. They are also very expensive.
Barriers are mostly to do with poor service organization, failure of adherence and screening.
