Objective: To examine the economic burden of and treatment patterns for con
gestive heart failure (CHF) in a managed care population.
Study Design: Retrospective review of medical and pharmacy claims.
Patients and Methods: We reviewed integrated medical and pharmacy claims da
ta from 6 independent-practice-association model health maintenance organiz
ations to identify patients diagnosed with CHF. Of the approximately 1.4 mi
llion people enrolled in these managed care plans during the study period (
January through December 1994), a total of 2777 patients (mean age, 56.9 ye
ars) met the study criteria, which included diagnostic codes for CHF and cl
aims eligibility of at least 1 year. We reviewed the charges incurred by pa
tients diagnosed with CHF for the 6 months after the initial CHF medical cl
aim. We also examined the treatment received by each of these patients.
Results: During the study period, 378 of the 2777 patients with CHF (14%) w
ere admitted to the hospital at a cost of almost $3 million tan average of
$7863 per hospitalized patient). Seventy-eight percent of the study populat
ion received prescription drugs, at an average per-patient cost of $942. Th
e most commonly prescribed drug class was angiotensin-converting enzyme inh
ibitors, prescribed for 38% of patients. Calcium channel blockers were pres
cribed for 33% of patients, but beta-blockers were prescribed for only 18%
of patients. Hospitalization accounted for 54% of the total cost for CHF tr
eatment, with prescription drugs accounting for 38%.
Conclusion: Congestive heart failure represents a significant financial bur
den within a non-elderly managed care population. Improved management of th
e condition is needed to reduce the morbidity and mortality, as well as the
costs of treatment, associated with CHF. Considerable data indicate that d
rugs such as beta-blockers and angiotensin-converting enzyme inhibitors can
significantly decrease the morbidity and mortality of CHF. Further investi
gation is needed into whether increased use of prescription pharmaceuticals
may reduce hospitalization rates and overall costs for CHF in this setting
