Seasonal Differences in Home Dialysis Uptake and Initiating Dialysis in the Hospital

Completed

• Conditions: Dialysis; Peritoneal Dialysis; Hospitalizations
• Interventions: Other: Season of Year; Other: Hospitalized 14 days prior to dialysis

• Registration Number: NCT04935827
• Lead Sponsor: University of Southern California

Brief Summary

This study will investigate whether home dialysis uptake varies by the season of year. We will also investigate whether hospitalizations around the time of dialysis also vary by season of year and whether hospitalizations are associated with reduced home dialysis starts and sustained home dialysis uptake.
