title: A longitudinal study into the new and long-term use of self-monitoring blood glucose strips in the UK.
abstract: OBJECTIVE
  To determine the impact of self-monitoring blood glucose (SMBG) strip use in patients with type 2 diabetes in the UK.
  
  
  METHODS
  The study period was April 1, 2004 to July 31, 2005. Data from primary care was extracted from The Health Improvement Network database. Patients identified with diabetes and matching the inclusion criteria were defined as new users of SMBG, prevalent users, or non-users. Patients were also defined as treated with insulin, with oral agents (OA), or not pharmacologically treated. Change in glycosylated hemoglobin (HbA(1c)) at baseline and after 12 months was compared.
  
  
  RESULTS
  2559 patients met the inclusion criteria. For new users, HbA(1c) fell by 0.59% (P=0.399) for those treated with insulin, 1.52% (P<0.001) for those treated with OA, and 0.51% (P<0.001) for no treatment. In prevalent users, changes were 0.31% (P<0.001), 0.34% (P<0.001), and 0.09% (P=0.456), respectively. In non-users, changes were 0.28% (P=0.618), 0.42% (P<0.001), and an increase of 0.05% (P=0.043), respectively. A significant decrease in mean HbA(1c) was associated with increasing strip use in OA patients newly initiated on strips.
  
  
  CONCLUSIONS
  This observational study showed a significant decrease in HbA(1c) for new users of SMBG treated either non-pharmacologically or with OA, and for prevalent users treated with insulin or OA. Reduced HbA(1c) with increasing strip use was observed but was only significant for OA-treated new users. This suggests that SMBG use has a role in the treatment of non-insulin treated patients with type 2 diabetes.
