As DM is a chronic disease and needs lifelong care, it's of utmost importance that the patient is geared to self-care. Even though regular clinic visits are important, patients must know to check their blood sugar levels, take care of hands and feet, dietary management etc. Improving patients knowledge at the time of diagnosis, using mass media to improve knowledge , including NCDs in to school curricula are some initiative. Also another initiative is to enhance health literacy among people. If health literacy is not adequate, people will not understand the health messages or the contents in it . 

I hope this helps 

Thanks Anuji for your informative answer..

My personal experience, both as a clinician and in my Therapeutic Patient Education activities (with Diabetes Education Study Group DESG in Switzerland and on an international level) have taught me that diabetes education will be confined to the diabetes specialist (physicians and nurses) community as long as it is not embedded in broader initiatives such as the WHO NCD strategy. Just now, my country, Switzerland, has set up a general nation-wide scheme  for an enhanced systematic and comprehensive approach to NCDs, such as cancer, cardiovascular disease and diabetes,to which mental health has been added as a subject. During the next 10 to 15 years, Swiss health care providers will be confronted  with the question of enhancing the efficacy of their intervention both in primary, secondary, and tertiary prevention. To give you an impression of the actual situation, see http://www.who.int/nmh/countries/che_en.pdf, and for a look at the Swiss strategy: http://www.bag.admin.ch/gesundheit2020/index.html?lang=en. Unfortunately, the detailed NCD program is not available in an English language version, but French and Italian translations exist.
