(HealthDay)—Left ventricular assist devices (LVADs) improve quality of life in ambulatory patients with advanced heart failure, but increase lifetime costs, according to a study published online Jan. 11 in JACC: Heart Failure.

Jacqueline Baras Shreibati, M.D., from the Stanford University School of Medicine in California, and colleagues examined the cost-effectiveness of LVADs in ambulatory patients with advanced . The costs of care were determined among Medicare beneficiaries before and after LVAD implant in 2009 to 2010. These costs and efficacy data from the literature were used in a Markov model to project the incremental cost-effectiveness ratio (ICER) of destination LVAD therapy versus .

The researchers found that LVAD implant had a mean cost of $175,420. The mean cost of readmission was significantly lower before versus after LVAD ($12,377 versus $19,465; P < 0.001), while similar monthly outpatient costs were seen ($3,364 versus $2,974; P = 0.54). Compared with medical management, LVAD increased quality-adjusted life-years (4.41 versus 2.67), readmissions (13.03 versus 6.35), and costs ($726,200 versus $361,800) in the lifetime simulation model, yielding an ICER of $209,400 per quality-adjusted life-year gained and $507,400 per life-year gained. These results were sensitive to LVAD readmission rates and costs of outpatient care; if these parameters were 50 percent lower the ICER would be $86,900.

"LVADs may provide good value if outpatient costs and adverse events can be reduced," the authors write.
