Abstract
Introduction

The active insulin time (AIT) is an adjustable parameter of the MiniMed™ 780G (MM780G) system. We analyze glucose outcomes and patient perception at different AIT settings.

Method

We conducted a quasi-experimental study on type 1 diabetes mellitus patients treated with MM780G, seen consecutively in our center. AIT was set at 2, 3 and 4h consecutively, during a 2-week period each. Glucose metrics, insulin delivery and a questionnaire about patient perception were evaluated. At the end, results were discussed with the patient and the most appropriate AIT was agreed upon.

Results

A total of 58 users were included, aged 18–65 years, 58.6% of whom were women. At baseline, 2-h AIT was set in 6.70% of the patients, >2-h AIT and ≤3-h AIT in 24.67%, >3-h AIT and ≤4-h AIT in 58.62%, and >4-h AIT in 10.34%. Under the 2-h AIT, TIR increased by 2.28% and 6.35% vs 3- and 4-h AIT, respectively. The auto-correction boluses percentage was 21.19% at 2-h AIT, 16.90% at 3-h AIT and 14.40% at 4-h AIT.

A total of 41.4% of the users considered that 3h was the AIT that most met their needs and 43.1% felt safer and less vulnerable to hypoglycemia at this setting. After trying on different AIT durations, 2h increased from 6.7% of participants to 62%.

Conclusion

At 2-h AIT, the system delivers more auto-correction insulin and improves TIR vs 3- and 4-h AIT. Patients feel safer and less susceptible to hypoglycemia at 3-h AIT, but 2 out of 3 would rather choose the 2-h AIT after knowing glycemic outcomes.

Resumen
Introducción

La duración de insulina activa (DIA) es un parámetro ajustable del sistema MiniMed™ 780G (MM780G). El presente estudio analiza los resultados glucémicos y la percepción del paciente con diferentes programaciones de la DIA.

Materiales y métodos

Estudio cuasi-experimental sobre pacientes con diabetes tipo 1 tratados con MM780G en nuestro centro. La DIA se estableció en 2, 3 y 4 horas durante un periodo de 2 semanas cada una. Se evaluaron resultados glucémicos, dosificación de insulina y percepción del usuario. Al final del estudio, se acordó con el paciente la DIA más apropiada.

Resultados

Se incluyeron 58 pacientes (18-65 años, 58,6% mujeres). Inicialmente, tenían DIA de 2 horas el 6,70% de los usuarios, > 2 horas y ≤ 3 horas el 24.67%, > 3 y ≤4 horas el 58.62%, y > 4 horas el 10,34%. Con DIA de 2 horas, el TIR aumentó +2,28% y +6.35% frente a 3 y 4 horas. La autocorrección fue 21.19%, 16.90% y 14.40% con 2, 3 y 4 horas respectivamente. El 41,4% de los usuarios consideraba que 3 horas se ajustaba mejor a sus necesidades y el 43,1% se sentía más seguro y menos vulnerable a las hipoglucemias con esta programación. Tras probar diferentes DIA, 2 horas pasó del 6,7% al 62% de los participantes.

Conclusiones

La DIA de 2 horas aumenta la auto-corrección y mejora el TIR, comparado con 3 y 4 horas. Los pacientes se sienten más seguros y menos vulnerables a la hipoglucemia con DIA de 3 horas, pero 2 de cada 3 elegiría 2 horas tras conocer los resultados glucémicos.
