Patient-reported outcomes for older adults on CamAPS FX closed loop system

Area of Science:

• Endocrinology and Metabolism
• Biomedical Engineering
• Diabetes Technology

Background:

• The CamAPS FX hybrid closed loop (CL) system demonstrates improved glycemic control (time in range, HbA1c) in type 1 diabetes (T1D).
• Limited data exists on the impact of CL systems on patient-reported outcomes (PROs), especially in older adult populations.

Purpose of the Study:

• To evaluate the effects of the CamAPS FX CL system on PROs in older adults (≥60 years) with T1D.
• To compare the CamAPS FX CL system with sensor-augmented pump (SAP) therapy regarding patient experiences and outcomes.

Main Methods:

• Open-label, randomized, multi-site study involving 35 older adults with T1D.
• PRO surveys administered at baseline and after 16-week periods of CL or SAP use.
• Qualitative interviews conducted with 19 participants to explore experiences with the CL system.

Main Results:

• Significant improvements observed in the Diabetes Distress Scale score (overall, powerlessness, physician distress) after 16 weeks of CL use.
• Increased trust reported on the Glucose Monitoring Satisfaction Survey with CL system use.
• Interviewees consistently reported benefits of 'improved glycaemic control' and 'worrying less about diabetes'.

Conclusions:

• The CamAPS FX CL system shows promise for improving PROs and subjective user experience in older adults with T1D.
• These findings complement existing evidence of glycaemic benefits, suggesting a holistic improvement in managing T1D for this demographic.
