Patient-Doctor Contact Interval and Clinical Outcomes in Continuous Ambulatory Peritoneal Dialysis Patients

Area of Science:

• Nephrology
• Internal Medicine
• Clinical Research

Background:

• The optimal frequency of patient-doctor contact (PDC) for individuals on peritoneal dialysis (PD) is not well-established.
• Understanding the impact of PDC intervals on clinical outcomes is crucial for managing PD patients.

Purpose of the Study:

• To investigate the association between the PDC interval and clinical outcomes in continuous ambulatory PD (CAPD) patients.
• To determine if a shorter PDC interval is associated with improved patient survival and reduced complications.

Main Methods:

• A retrospective cohort study included CAPD patients from Guangzhou between 2006 and 2012.
• Patients were categorized into high (PDC interval ≤2 months) and low (PDC interval >2 months) frequency groups based on ROC curve analysis.
• Biochemical data, clinical events, and outcomes were compared between the groups.

Main Results:

• Patients with high PDC frequency (≤2 months) demonstrated significantly better patient-survival rates at 1, 3, and 5 years compared to the low PDC frequency group (p < 0.001).
• High PDC frequency was associated with lower rates of peritonitis (0.17 vs. 0.23 episodes/patient-year; p < 0.001) and hospitalization (0.49 vs. 0.67 episodes/patient-year; p < 0.001).
• A PDC interval of ≤2 months was independently associated with better patient survival (HR 0.60; p = 0.006) after adjusting for confounders.

Conclusions:

• A patient-doctor contact interval of 2 months or less is associated with superior clinical outcomes in CAPD patients.
• Shorter PDC intervals should be encouraged to improve patient survival and reduce complications in this population.
