Dialysis, Hospitalizations, Peritoneal Dialysis
Conditions
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.
Interventions
OTHERSeason of Year
We stratify patients into 4 groups based on the season of the year (between 12/1/2007-11/30/2017) * Winter: December, January, February * Spring: March, April, May * Summer: June, July, August * Fall: September, October, November
OTHERHospitalized 14 days prior to dialysis
We further stratify patients into 3 groups based on whether they were hospitalized within 14 days prior to dialysis * Group 1: No hospitalization prior to dialysis * Group 2: Hospitalized within 14 days prior to dialysis for an acute infectious respiratory condition or one of the following acute cardiac conditions (arrhythmia, myocardial infarction, stroke, or fluid overload) * Group 3: Hospitalized within 14 days prior to dialysis for a condition not in Group 2
