Cost of hospitalizations for heart failure: sodium retention versus other decompensating factors.

OBJECTIVE
To determine the cost of heart failure-related hospital admissions and to compare the cost of admissions for sodium retention with the cost of admissions for other decompensating factors.


DESIGN
Retrospective, non-experimental, cost analysis.


SETTING
Midwestern university-affiliated, tertiary care, medical center.


SAMPLE
Two hundred seven heart failure-related admissions, 117 (57%) of which were for sodium retention leading to volume overload.


OUTCOME MEASURES
Cost of hospitalization.


PROCEDURE
Data obtained from the patient and financial records of patients hospitalized for heart failure in 1992 were analyzed using the ratio of cost-to-charge accounting procedure.


RESULTS
The total cost was $2,442,720 for the 207 heart failure-related admissions; the average cost was $12,400 per admission. Approximately half of the cost of the hospitalizations was expended in the 4 cost centers comprising routine and critical care services, which incorporate room charges and nursing care. Another one third of the cost was for supplies, medications, and laboratory tests. Admissions as a result of sodium retention had lower costs than admissions as a result of other factors.


CONCLUSION
The cost of hospitalization for heart failure is high. Routine services, supplies, medications, and laboratory tests used by these patients contribute to the high cost of care. Improved outpatient management strategies are necessary to reduce hospital admissions as a result of sodium retention.
