Dialysis Facility ComparePrevalence Data
As reported here, prevalence reflects the number of people on chronic maintenance dialysis in Network 11 on December 31st of the calendar year. Patients are reported according to their geographic residence to determine and compare prevalence rates. Prevalence rates are expressed as the number of people on dialysis per the general population in the area (i.e., per million persons).
Importance of Prevalence Rates
Comparing prevalence rates (which have been standardized on the same unit of population) allows you to see if a certain disease is significantly more prevalent in some areas than in others. Also, prevalence rates can be applied to future population projections. Such estimates can be useful for long-range health care planning and for comparing prevalence among regions.
Patients Included
All patients in Network 11 who are on chronic maintenance dialysis in ESRD facilities at the end of the calendar year are included in the geographic origin and primary diagnosis tables. Almost all Medicare and non-Medicare patients are included for Network 11 even though the national ESRD Medical Information System collects data on Medicare patients only. (Nationally, approximately 5% - 7% of ESRD patients are unentitled.)
Patients Excluded
Except for the last page in this prevalence section, prevalence data reported reflect the dialysis patients only. These data do not include: (1) individuals with functioning renal transplants, except on the last page; and (2) a very small number of Network 11 residents who may be treated at facilities in adjacent states.
