How are the Patient Survival Rates calculated?
A certain number of deaths are expected in any group. For patients of a dialysis facility, this number is affected by the patients’ age, size, race, sex, ethnicity, whether or not they have diabetes, how long they have had renal failure, and whether they had other health problems when they started dialysis. To calculate the expected number of deaths, multiply: The national death rate for patients on dialysis x The number of years that the patient was treated at the facility. = The expected number of deaths for patients on dialysis. The expected deaths are calculated for all patients in the facility to give the total number of deaths expected for the 4-year period at the facility. Actual compared to expected To calculate the relative patient mortality, divide: The actual number of deaths from 2000 to 2003 for patients on dialysis. รท The expected number of deaths for patients on dialysis. = Relative Patient Mortality Relative Patient Mortality Facility Category Rating 0.8 or less Better
