Knowledge of diabetes among type 2 diabetes patients attending a primary health care clinic in Sri Lanka.

Patients' knowledge about their illness is considered important in controlling diabetes and preventing complications. A descriptive, cross-sectional study was conducted among patients attending the diabetes clinic of a primary care level hospital in Moratuwa, Sri Lanka. During a 1-month period in 2009 all consenting patients diagnosed with type 2 diabetes who had been attending the clinic for more than 3 months were included in the study. Using an interviewer administered, structured questionnaire 150 patients (135 females, 15 males) answered 25 questions about diabetes knowledge (scored x4 to give score range 0-100). A majority of patients (70.0%) had a good score (> 65) on the knowledge test but critical gaps in knowledge were revealed, especially regarding knowledge about symptoms of poor control and importance of regular follow-up. Although patients with longer duration of diabetes had higher mean knowledge scores, they also had higher fasting blood glucose levels. Education programmes are needed to address critical gaps in patients' knowledge.
