Introduction: While there have been continued advances in insulin treatment for diabetes since the discovery of insulin 100 years ago, some unmet needs still remain, including those related to mealtime insulin (MTI). The objective of this study was to explore the impacts related to MTI and the relative burden of the impacts on people with diabetes.
Methods: This study was conducted across two phases, namely, a qualitative and quantitative phase. People with type 1 and 2 diabetes using MTI in the USA and UK were recruited for the study. The qualitative phase involved 30 interviews to explore the impacts associated with MTI. Based on the results of the qualitative phase, a list of impacts was developed to evaluate the importance of MTI impacts using best-worst scaling.
Results: A total of 30 participants completed interviews, and 336 completed the quantitative phase. Participants described a range of impacts associated with MTI, including psychological (72.0%), social (63.0%), work/school (53.8%), and sleep (51.7%). Impacts for the quantitative phase were categorized under the following domains: diabetes distress, diabetes management, work productivity, and social. The three most burdensome impacts were related to diabetes distress, but the diabetes management domain contributed more than diabetes distress to the relative burden. There were minor differences in the relative importance of impacts by diabetes type, diabetes duration, and experience with continuous glucose monitoring.
Conclusion: This study confirms that people with diabetes using MTI still have an array of unmet needs, including those related to the management of their diabetes and the emotional distress of having diabetes. These findings may be useful for healthcare provider (HCP)-patient interactions to ensure HCPs are allowing patients an opportunity to discuss their experiences with MTI.
