An Observational Study Evaluating Patient Satisfaction and Quality of Life Associated With Switching Insulin

The purpose of this study is to estimate the direct costs associated with switching, in either direction, between a rapid-acting analog therapy and short-acting human insulin therapy within the first year following the switch. The additional goals are: 1)to assess the impact of a switch from or to a rapid-acting analog insulin therapy on patient treatment satisfaction, 2) to assess the impact of a switch from or to a rapid-acting analog insulin therapy on patient quality of life, 3) to assess the impact of switch from or to the rapid-acting analog insulin therapy on the quality of metabolic control and, 4) to estimate the total costs (direct and indirect) associated with switching, in either direction between rapid-acting analog and short-acting human insulin within the first year following the switch.
