A Research Study Looking at How the Use of NovoPen® 6 for Treatment With Tresiba® & Fiasp® Affects the Blood Sugar Level in Patients With Type 1 Diabetes as Part of Local Clinical Practice

The purpose of this study is to collect information on how NovoPen® 6 works with Tresiba® \& Fiasp® for treatment of people with type 1 diabetes and see if the use of NovoPen® 6 can help participants achieve better blood sugar levels. Participants will use Tresiba® \& Fiasp® in NovoPen® 6 as prescribed to participants by the study doctor. NovoPen® 6 is a smart pen, which collects and stores the date and time of injections and number of units of insulin participants have taken. NovoPen® 6 can transfer participants insulin dosing information to the mobile application, which participants use to see their continuous blood sugar level. This will allow participants to see their insulin doses along with continuous blood sugar level in the mobile application. Participants will keep using their own continuous blood sugar monitoring device and the mobile application to see these data during the study. The study will last for about 9-11 months. Participants will be asked to complete 2 questionnaires in this study. One questionnaire is about overall satisfaction of using a digital health solution and other is about quality of life. Participants will complete these questionnaires during their normally scheduled visit with the study doctor, on 2 separate occasions
