Continuous glucose monitoring (CGM) metrics and self-reported disease characteristics (severe hypoglycemic events [SHEs], HbA1c) warrant further description in people with T1D using CGM and pumps, including hybrid closed-loop systems (HCLS) . We conducted a one-time online survey of adults with T1D in the T1D Exchange Registry or online communities, where ∼50% of participants contributed up to 1 year of CGM data. Patients were asked about their medical history (SHEs, HbA1c) , while glucose management indicator (GMI) , prolonged hypoglycemic events ( Disclosure L.M.Laffel: Advisory Panel; Medtronic, Roche Diabetes Care, Consultant; Boehringer Ingelheim International GmbH, Dexcom, Inc., Dompé, Insulet Corporation, Janssen Pharmaceuticals, Inc., Lilly Diabetes, Novo Nordisk, Provention Bio, Inc.

Trials of continuous glucose monitors (CGMs) and hybrid closed-loop systems (HCLS) demonstrate improvements in glycemia with reductions in hypoglycemia in T1D, but there is limited real-world data on how these technologies impact the prevalence of impaired awareness of hypoglycemia (IAH) , severe hypoglycemic events (SHEs) , and glycemic control. We conducted a one-time online survey of adults with T1D in the T1D Exchange Registry and online communities. Self-reported medical histories (insulin delivery method, HbA1c, IAH, SHEs) and CGM data were collected. 2044 patients (mean age 43 y, mean T1D duration 26 y, 72% female, 95% White) completed the survey. Most reported using CGMs (92%) ; 953 also used HCLS. Mean HbA1c was 6.89%; 41.5% had an HbA1C of ≥7%; 30.7% reported IAH; 19.8% had ≥1 SHE in the prior year; 12.0% had ≥2 SHEs in the prior year; 9.6% had IAH + ≥1 SHE; and 6.6% had IAH + ≥2 SHEs (Table) . Rates of SHEs and IAH + SHEs were lower in CGM users and CGM + HCLS users than in non-CGM users; however, among CGM + HCLS users, 16.6% reported ≥1 SHE, 8.7% ≥2 SHEs, 7.8% IAH + ≥1 SHE, and 4.7% IAH + ≥2 SHEs. Also, 35.6% of CGM + HCLS users had an HbA1C of ≥7%. In a patient cohort with high rates of technology adoption, rates of SHEs and IAH remained high, with a significant proportion of patients not achieving targeted glycemic control, indicating the need for novel T1D treatments.

VOCAL was an observational study of the effect of long-term ivacaftor on real-world clinical outcomes and healthcare resource utilization (HCRU) in people with cystic fibrosis (pwCF) in Italy, the Netherlands, and the UK.pwCF aged ≥6 years with non-G551D-CFTR gating mutations were eligible. Prospective data were collected up to 48 months after enrollment; retrospective data were collected to ensure that 12 months of pre-ivacaftor data were available. Endpoints included absolute change from baseline in percent predicted forced expiratory volume in 1 second (ppFEVSeventy-three eligible pwCF were enrolled and received ivacaftor; 65 (89.0%) completed the study (48 [65.8%] completed ≥48 months of ivacaftor). During the first 6 months of ivacaftor, ppFEVThese results demonstrate the positive long-term effectiveness of ivacaftor on clinical outcomes and HCRU in pwCF with non-G551D-CFTR gating mutations in real-world settings.
