• Study description:
  The use of metformin in patients with type 2 diabetes (2D) is rarely associated with lactic acidosis (LA) provided that contraindications do not exist. Though the safety information available in patients with moderate-severe chronic kidney disease (CKD) is limited and inconclusive, the use of metformin in this population is wide. This is a case-control study to assess the association between metformin and LA in patients with 2DM and moderate-severe CKD. It will be performed with computerized registered data from 16 Spanish hospitals and their areas of influence in primary care from 2010 to 2015, comprising more than 50 million person-years follow-up. Logistic regression will be used to assess the crude and adjusted risk of LA associated to metformin use overall and stratifying by use and dose categories and CKD stage. The overall case fatality rate of LA as well as the case fatality rate stratified by CKD stage will be calculated. Observation bias will also be explored.
