Case-mix and treatment in end-stage renal disease: hemodialysis v peritoneal dialysis.
The University of Southern California School of Medicine conducted a nationwide survey of 336 nephrologists to obtain demographic and clinical data on 6,411 patients with end-stage renal disease (ESRD). Patient demographic data, along with ESRD etiology and comorbid conditions noted by the physician, were compared across various modalities of dialysis. Characteristics of the treatment provided were differentiated by the mode of dialysis and the location of the patient encounter. Results of the analysis show that patients on peritoneal dialysis are more likely to be female and have higher rates of diabetes compared with hemodialysis (HD) patients. Statistically, patients on intermittent peritoneal dialysis are older, more likely to be black, and have a higher incidence of cardiovascular conditions. Continuous ambulatory peritoneal dialysis patients have greatest problem severity and require more physician time and more complex services, whereas home HD patients require the greatest number of diagnostic tests and therapeutic procedures. Hospital inpatient care shows greater case-mix severity and more intensive treatment, but this does not differ by the mode of dialysis. Finally, patients of freestanding dialysis facilities are more likely to have hypertensive renal disease, whereas patients at hospital-based facilities are older, more likely to be seen in the hospital, have more urgent and severe problems during dialysis rounds, and require more physician time, more complex services, and more diagnostic tests and therapeutic procedures.
