title: Clinical and cost-effectiveness of left ventricular assist devices as destination therapy for people with end-stage heart failure: a systematic review and economic evaluation.
abstract: OBJECTIVE
  The clinical and cost-effectiveness of left ventricular assist devices as destination therapy for people with end-stage heart failure is assessed through a systematic review and economic evaluation.
  
  
  METHODS
  Systematic review was performed of randomized controlled trials, quasiexperimental studies, case series, and case studies identified through searching eighteen electronic databases, bibliographies, and consultation with experts and manufacturers. Studies assessed survival, functional capacity, and quality of life. Cost-effectiveness was assessed through a 5-year decision analytic model to estimate the incremental cost-effectiveness ratio for using left ventricular assist devices compared with usual care.
  
  
  RESULTS
  Six studies met the inclusion criteria, showing that left ventricular assist devices appear beneficial, improving survival and quality of life. Adverse events are a serious concern. The economic evaluation showed that left ventricular assist devices had a cost per quality adjusted life year of 170,616 pounds. Sensitivity analysis showed that the cost-effectiveness was not sensitive to changes in costs or utility.
  
  
  CONCLUSIONS
  Although left ventricular assist devices appear clinically effective as destination therapy, it is unlikely they will be cost-effective unless costs decrease or the benefits of their use increase.
