A 2018 clinical practice pattern in the management of diabetes in India and Nepal: a three-city study

Knowledge, awareness, and practices with regard to diabetes management in south Asia are not known. This study aimed to determine current clinical practices with regard to managing diabetes in Nepal and India. Doctors attending conferences in Delhi, Guwahati, and Kathmandu were evaluated regarding their diabetes treatment preferences using a standardized questionnaire having 34 multiple-choice questions. The questionnaire evaluated doctor’s preferences on therapeutic lifestyle modification, pharmacotherapy, and insulin injection practices. From a total of 409 filled questionnaires which were collected, 261, 75, and 73 questionnaires from New Delhi, Guwahati, and Kathmandu, respectively, which fulfilled all criteria, were analyzed. The mean age of doctors was 42.26 ± 11.99 years. Low carbohydrate, high protein was the most frequently recommended diet plan. The use of carbohydrate counting in practice was non-existent. Self-monitoring of blood glucose (SMBG) is commonly used in practice with 1–2 times per day checking. The preferred second, third, and fourth oral agents after metformin were sulfonylureas (53.05%), glucosidase inhibitors (37.16%), and dipeptidyl-peptidase-4 inhibitors (DPP4i) (42.79%) respectively. Glimepiride (73.83%) and gliclazide (28.60%) were the most preferred sulfonylureas. Teneligliptin (31.54%), sitagliptin (23.71%), linagliptin (22.24%), and vildagliptin (16.38%) were the preferred DPP4i. Dapagliflozin (30.56%), empagliflozin (20.29%), and canagliflozin (8.85%) were the preferred sodium-glucose co-transporter-2 inhibitor (SGLT2i). Insulin use was delayed in type-2 diabetes, typically initiated only after glycemic control not adequate with five oral anti-diabetes agents (OADs) (50.36%). The most preferred insulin was basal insulin analogue (47.68%) followed by neutral protamine hagedorn (NPH) insulin (22.24%). Most patients received < 20 U of insulin/day (56.96%). The most commonly used short-acting insulin in pregnancy was lispro (204; 49.88%). The preferred long-acting insulin in pregnancy was NPH insulin (180; 44.01%). Lack of use of digital technology, less use of lifestyle modifications, delayed use of insulin, preference for multiple OADs, popularity of sulfonylureas and alpha-glucosidase inhibitors (AGIs), and late use of SGLT2i were some of the key highlights of diabetes practice in south Asia.
