Patient selection to peritoneal dialysis versus hemodialysis according to comorbid conditions
Insights
Patients undergoing peritoneal dialysis (PD) had fewer comorbid conditions than those on hemodialysis (HD), especially younger diabetics. PD selection was not linked to higher cardiovascular risk but a slight increase in peripheral vascular disease.
Area of Science:
- Nephrology
- Epidemiology
- Healthcare Management
Background:
- End-stage renal disease (ESRD) management involves choosing between peritoneal dialysis (PD) and hemodialysis (HD).
- Patient selection for dialysis modality can be influenced by comorbid factors, impacting outcomes.
- Understanding these influences is crucial for optimizing patient care in ESRD.
Purpose of the Study:
- To analyze patient selection for PD versus HD based on comorbid factors.
- To identify demographic and clinical characteristics associated with PD and HD assignment.
- To assess the comorbidity burden and specific risk factors for patients undergoing PD compared to HD.
Main Methods:
- Analysis of a historical prospective sample of 2,420 non-diabetic and 1,738 diabetic Medicare patients incident from 1986-87.
- Collection of data on comorbidity, ESRD diagnosis, and sociodemographic factors from the USRDS special study.
- Statistical adjustment for race, gender, diabetes, and age to compare comorbidity levels between PD and HD patients.
Main Results:
- Patients selected for PD were more likely to be white, diabetic, and younger than HD patients.
- PD patients exhibited a reduced total count of comorbid factors compared to HD patients, particularly diabetics under 60 (p < 0.01).
- PD selection showed no increased cardiovascular comorbidity risk but a 20% higher likelihood of peripheral vascular disease (p = 0.02).
Conclusions:
- Patient selection for PD versus HD is associated with differing comorbidity profiles.
- PD may be a suitable option for specific patient groups, including younger diabetics, with careful consideration of peripheral vascular disease risk.
- Further research into modality-specific outcomes based on comorbidity is warranted.
Abstract:
An historical prospective sample of 2,420 non-diabetic and 1,738 diabetic Medicare patients incident from 1986-87 was analyzed for the selection of patients to peritoneal dialysis (PD) and hemodialysis (HD) according to comorbid factors. Data measuring the degree of comorbidity, describing the major diagnosis leading to end-stage renal disease (ESRD), and reporting other sociodemographic factors for incident ESRD patients were collected in a special study of the USRDS. Patients selected to PD were more likely to be white (greater mortality risk), diabetic (greater mortality risk), and younger (lower mortality risk) than patients assigned to HD. Estimates of the overall level of comorbidity with adjustment for race, gender, diabetes, and age provided evidence of a reduced total count of comorbid factors for PD compared to HD, particularly among diabetic patients under 60 years of age (p < 0.01). Assessment of selected risk factors, with adjustment for age and diabetes, indicated that patients selected to PD were not at greater comorbid risk according to cardiovascular factors but demonstrated a 20 percent increase in the likelihood of peripheral vascular disease (p = 0.02).
