Abstract
OBJECTIVE - To compare health-related quality of life (HRQOL) in patients with diabetes receiving insulin lispro with patients receiving regular human insulin (Humulin R). RESEARCH DESIGN AND METHODS - We performed two randomized comparative studies over a 6-month period (3 months per treatment). Primary analyses used crossover baseline to 3-month changes in HRQOL scores. Ninety-three principal investigators in Canada, France, Germany, and the U.S. participated in these studies. One HRQOL crossover study included 468 patients with type l diabetes; the other HRQOL crossover study included 474 patients with type II diabetes. In both studies, patients were taking insulin at least 2 months before enrollment. Primary outcomes included two generic HRQOL domains, energy/fatigue and health distress, and two diabetes-specific domains, treatment satisfaction and treatment flexibility. Thirty secondary outcomes included both generic and diabetes- specific measures. Secondary outcome domains were controlled for multiplicity in the analyses. RESULT - Primary analyses showed that treatment satisfaction scores (P < 0.001) and treatment flexibility scores (P = 0.001) were higher for insulin lispro in type I diabetic patients. No other significant treatment differences were detected using the data from these 6 month crossover studies. CONCLUSIONS - Treatment satisfaction and treatment flexibility were significantly improved in patients with type I diabetes using insulin lispro. Other HRQOL findings were comparable for insulin lispro and regular human insulin. Insulin lispro appears to have a measurable impact on lifestyle benefits in patients with type 1 diabetes, as demonstrated by increased treatment satisfaction and treatment flexibility.
