Almost 60% of patients with type 2 diabetes and moderate to severe renal impairment have been prescribed drugs at odds with expert guidelines, an Australian general practice study shows.

Drawing on the NPS MedicineInsight database, researchers from the University of Melbourne reviewed the records of 3500 patients who recorded at least two eGFR results of <60mL/min/1.73m2 and were prescribed a non-insulin diabetes medication over a 30-month period.
