This study examines dialysis nurses’ perspectives on the use of continuous glucose monitoring (CGM) in hemodialysis (HD) patients with insulin-treated diabetes. Through eight semi-structured interviews, nurses highlighted how CGM improved the patients’ and nurses’ ability to monitor patients’ glucose levels, enhancing patient engagement and nursing practices. The nurses emphasized the value of real-time glucose data during dialysis sessions, allowing for timely adjustments and better glycemic control. Despite these advantages, they also noted challenges, including a lack of knowledge regarding CGM technology. Overall, the nurses viewed CGM as a beneficial tool, providing a clearer understanding of patients’ glucose patterns. Furthermore, the findings reveal that CGM fosters better communication and awareness among healthcare professionals and patients, ultimately improving the care provided to insulin-treated HD patients.
