Clinician Experiences with Hybrid Closed Loop Insulin Delivery Systems in Veterans with Type 1 Diabetes: A Qualitative Study
ABSTRACT
Background:
Hybrid closed loop (HCL) insulin pumps adjust insulin delivery based on input from a continuous glucose monitor. Several systems are FDA approved and associated with improved time in range, reduction in hemoglobin A1c, and decreased incidence of hypoglycemia. Major diabetes guidelines differ in their strength of recommendations regarding the use of HCL systems. Overall, limited information about the factors that influence HCL pump clinical decision-making is available, especially among endocrinology clinicians.
Objective:
The study objective is to describe the knowledge and attitudes, network support, and self-efficacy regarding HCL insulin delivery systems among endocrinology clinicians in the Ann Arbor Veterans Affairs (VA) Healthcare System.
Methods:
Following a descriptive approach, this qualitative study utilized semi-structured interviews and inductive thematic analysis. Thirteen endocrinologists, endocrinology fellows, and nurses were invited to participate in one-on-one phone interviews. Thematic analysis explored clinician perspectives on HCL insulin pump systems.
Results:
Participants (n=11) had experience within VA and university healthcare system endocrinology clinics. From their experiences, 4 themes were identified involving the evaluation and assessment of insulin pump candidates, prescribing challenges, clinical benefits of HCL pumps, and overall clinician confidence.
Conclusions:
Findings suggest that clinicians believe HCL systems have significant glycemic benefits but are not appropriate for all patients, especially those with cognitive impairment. HCL pump initiation is a multi-step process requiring an interdisciplinary team of healthcare clinicians to ensure patient and pump success. Furthermore, HCL systems improve clinician confidence in overall diabetes management. Clinical Trial: Not applicable
