Outcomes

Primary Outcomes

Questionnaire responses regarding patient satisfaction and opinion regarding use of continuous glucose monitoring system

Questionnaire responses regarding patient satisfaction and opinion regarding use of continuous glucose monitoring system: regarding how do subjects feel that using CGM impacted their glucose control on a scale of 1-5, with 1=strongly made it worse, 2=somewhat made it worse, 3=did not make it better or worse, 4=somewhat made it better, and 5=strongly made it better?; regarding what is the overall opinion of subject's experience with CGM use on a scale of 1-5, with 1=very negative, 2=negative, 3=neutral, 4=positive, 5=very positive.

Time frame: From enrollment until follow-up telephone visit 2-3 weeks after discharge

Questionnaire responses regarding patient satisfaction and opinion regarding quality of diabetes care

Questionnaire responses regarding patient satisfaction and opinion regarding quality of diabetes care: regarding how do subjects feel that using CGM impacted the diabetes care overall on a scale of 1-5, with 1=strongly made it worse, 2=somewhat made it worse, 3=did not make it better or worse, 4=somewhat made it better, and 5=strongly made it better.

Time frame: From enrollment until follow-up telephone visit 2-3 weeks after discharge

Questionnaire responses regarding patient familiarity with continuous glucose monitoring

Questionnaire responses regarding patient familiarity with continuous glucose monitoring: regarding degree of familiarity of CGMs in general and the different types of information provided by CGMs, what is the subject's familiarity on a scale of 1-5, with 1=very unfamiliar, 2=unfamiliar, 3=neutral, 4=familiar, 5=very familiar.

Time frame: From enrollment until follow-up telephone visit 2-3 weeks after discharge
