Dialysis patients who shared ChatGPT questions with nurses had lower phosphorus levels

Study title: Voluntary ChatGPT Query Sharing With Nurse Feedback and Serum Phosphorus in Peritoneal Dialysis Patients

Researchers followed 88 patients on peritoneal dialysis through a 3-month program and a 2-month follow-up. Twenty of them voluntarily sent screenshots of their ChatGPT questions to nurses over LINE and got feedback, and their phosphorus levels were compared with those of the other patients.

Introduction: This study examined whether voluntary ChatGPT query sharing with nurse feedback was associated with serum phosphorus in patients receiving peritoneal dialysis (PD). Methods: In this prospective longitudinal study, eighty-eight patients completed a 3-month program (T1-T3) and 2-month follow-up. Twenty shared ChatGPT query screenshots with nurses via LINE and received feedback. Linear mixed-effects models examined serum phosphorus and the ratio relative to the 12-month pre-program mean (PR-P12M). Res…

In brief

High phosphorus is a common concern in dialysis care, so low-cost ways to support diet education could be useful. The finding is an association from a small, self-selected group, and the study cannot show that the chatbot and nurse feedback caused the lower levels.

Main points

The prospective longitudinal study enrolled 88 peritoneal dialysis patients, of whom 20 shared ChatGPT queries with nurses.
Sharing was associated with lower serum phosphorus across 5 months (p = 0.025).
The month-2 difference was 0.687 mg/dL (95% CI 0.199-1.174).
The ratio to each patient's 12-month pre-program mean was also lower with query sharing (p = 0.008).

The gain

Peritoneal dialysis patients who shared their ChatGPT dietary queries with nurses and received feedback had lower serum phosphorus over 5 months than those who did not, including a 0.687 mg/dL lower level at T2.

The rundown

Patients completed a 3-month program (T1-T3) followed by 2 months of follow-up. The sharing group sent ChatGPT query screenshots to nurses via LINE and received feedback on them.

Linear mixed-effects models assessed serum phosphorus and its ratio to the 12-month pre-program mean (PR-P12M). Neither outcome showed a significant group × time interaction, so the difference was not shown to change over time.

The authors suggest a potential role for AI-assisted dietary information seeking within nurse-guided phosphorus education in peritoneal dialysis care.
