Results: 32 of the 35 articles were decision support systems that provided specific warnings, reminders, a set of physician guidelines, or other recommendations for direct action. The most important decisions of the systems were support for blood glucose control and insulin dose adjustment, as well as 13 warning and reminder articles. Of the 35 articles, there were 21 user interface items (such as simplicity, readability, font sizes and so on), 23 interaction items (such as Fit, use selection tools, facilitate ease of use and so on) and 31 item information items (such as Content guidance, diagnostic support and concise and so on).

Conclusion: This study identified important aspects of designing decision support system, It can be applied not only to diabetic patients but also to other decision support systems. Most decision support systems take into account a number of design criteria; system designers can look at design aspects to improve the efficiency of these systems. Decision support system evaluation models can also be added to the factors under consideration.
