Risk of hospitalization for chronic hemodialysis patients.

This study used primary data to analyze the incidence, causes and total days of hospitalization over a six-month period for a sample of chronic hemodialysis patients in one geographic area of the country. Patients were hospitalized most frequently for access-related and cardiovascular problems. Logistic regression analysis indicated that patients were more likely to be hospitalized if they had lower Karnofsky functional status scores, lower serum phosphate and protein levels, repeat access procedures, a negative hepatitis antigen, arthritis, psychiatric disorders, ischemic peripheral vascular disease or other cardiovascular conditions or were from larger households. Risk of hospitalization was not influenced by hemodialysis treatment characteristics. Recommendations for improved management of these high-cost patients were made, which could enhance quality of life and lower hospital-related costs.
