Preventive action can enhance patient care

The issue of screening for diabetes raises questions about whether it is likely to be an effective use of NHS resources. However, by the time many people are diagnosed they have already developed complications. As certain groups are at increased risk of developing type 2 (non-insulin dependent) diabetes, screening may be an effective way to identify them before complications arise. Primary health care professionals have an important role to play in identifying patients with diabetes and helping them manage the condition, encouraging lifestyle changes in those at greatest risk.
