Key clinical point: How patients with type 1 diabetes monitor their glucose is more important than how insulin is delivered.
Major finding: End-of-study hemoglobin A1c values were significantly lower, compared with baseline values, in patients with type 1 diabetes using real-time continuous glucose monitoring with multiple daily injections of insulin (7.0% [53 mmol/mol], P = .0002) or an insulin pump (6.9% [52 mmol/mol], P less than .0001) than those who used self-monitoring of blood glucose with multiple daily injections (8.0% [64 mmol/mol], P = .3574) or an insulin pump (7.7% [61 mmol/mol], P = .1).
Study details: A 3-year follow-up of the COMISAIR study, a prospective, real-world clinical trial with 94 patients with type 1 diabetes who used either multiple daily injections of insulin or an insulin pump with either real-time continuous glucose monitoring or self-monitoring of blood glucose.
