Abstract
Introduction

Automatic insulin delivery (AID) systems improve glycemic control and quality of life in individuals with type 1 diabetes (T1D). Our aim was to assess the feasibility, effectiveness, and safety of switching from a sensor-augmented pump (SAP) to AID in T1D subjects at high risk of hypoglycemia.

Materials and methods

A manufacturer-led program consisting of three sessions was implemented. Over three days, all patients completed the first session in-person, in groups of 6–12 people, to receive device training. Subsequently, the automatic mode was activated virtually (session 2), followed by online data download (session 3). Glucometric outcomes were evaluated after one month, along with serious adverse events (SAEs), technical incidents, and perceived satisfaction.

Results

The switch was performed in 125 patients, 56.8% of whom were women, with a mean age of 44.1 ± 14.9 years. 99.2% (n = 124) initialized auto-mode. There was an increase in time in range 70–180 mg/dL (64.3 ± 11.3 vs. 74.7 ± 11.2; p < 0.001) and a decrease in time below 70 mg/dL (4.1 ± 3.9 vs. 2.0 ± 1.8; p < 0.001) (N = 97). Forty-one related calls were received, with 10 requiring in-person visits. Medtronic technical service handled 92 related calls (0.74 per patient), from 47 different users (37.6%). One event of severe hypoglycemia was recorded as an SAE. Perceived security and satisfaction with the switch process were high in 91% and 92% of patients, respectively.

Conclusions

Massive switch from SAP to AID in T1D patients at high risk of hypoglycemia is feasible and safe through a hybrid program conducted in collaboration with the manufacturer.

Resumen
Introducción

Los sistemas automáticos de administración de insulina (AID) mejoran el control glucémico y la calidad de vida en personas con diabetes tipo 1 (DT1). Nuestro objetivo fue evaluar la viabilidad, efectividad y seguridad de un recambio masivo de sistema bomba-sensor (SAP) a AID en sujetos con DT1 y alto riesgo de hipoglucemia.

Material y métodos

Se realizó un programa grupal e híbrido de 3 sesiones a cargo del fabricante. En tres días, todos los pacientes realizaron presencialmente la primera sesión en grupos de 6-12 personas para entrenar el uso del dispositivo. De forma virtual, se activó el modo automático (sesión 2) y la descarga de datos online (sesión 3). Se evaluaron resultados glucométricos tras un mes, así como eventos adversos graves (EAG), incidencias técnicas y satisfacción percibida.

Resultados

El cambio de dispositivo se efectuó en 125 pacientes, 56,8% mujeres y edad media 44,1 ± 14,9 años. El 99,2% (n = 124) iniciaron modo automático. Se observó un aumento del tiempo en rango 70-180 mg/dL (64,3 ± 11,3 vs. 74,7 ± 11,2; p < 0,001) y una reducción del tiempo <70 mg/dL (4,1 ± 3,9 vs. 2,0 ± 1,8; p < 0,001) (N = 97). Recibimos 41 llamadas relacionadas, de las cuales 10 requirieron visita presencial. El servicio técnico de Medtronic atendió 92 incidencias relacionadas con el recambio (0,74 por paciente), provenientes de 47 usuarios (37,6%). Como EAG se registró una hipoglucemia grave. La seguridad y satisfacción percibidas con el proceso de cambio fue alta en el 91% y 92% de los pacientes.

Conclusiones

El recambio masivo de un sistema SAP a AID en pacientes con DT1 y alto riesgo de hipoglucemia es factible y seguro mediante un programa híbrido y en colaboración con el fabricante.
