The time to insulin therapy has increased in type 2 diabetes patients, but the reasons for this ‘unfavourable trend’ are unclear, claim researchers.
British and German researchers looked at whether the time to insulin therapy in type 2 diabetes patients had increased in primary care between 2005 and 2010. Data from general practices was collected on the time from first diabetes diagnosis (index date) and the first insulin prescription in 1,998 and 6,368 patients in the UK and Germany, respectively. All patients were over the age of 40 at their index date.
The median time to insulin therapy in primary care practices significantly increased in the UK and Germany, with the median time to insulin therapy increased from 1,700 days to 2,061 days between 2005 and 2010 in British patients. Mean final HbA1c values also significantly increased in both countries, with a value of 9.5% in 2005 to 9.8% in 2010 in British patients.
What this means for GPs
The researchers say that further research is required to determine the underlying reasons for this ‘unfavourable trend’ and noted that ‘the present study confirms previous results that insulin therapy is initiated in patients with type 2 diabetes at a point where HbA1c levels are high above target levels, resulting in an increased risk of developing diabetes complications.’ The researchers warn that ‘larger efforts are required to remove the barriers currently preventing earlier initiation of insulin therapy in patients with type 2 diabetes.’
