Pharmacoeconomic comparison of sequential IV/oral ciprofloxacin versus ceftazidime in the treatment of nosocomial pneumonia.
A retrospective, cost-effectiveness analysis was performed on 106 clinically evaluable patients who participated in a multi-centre, randomized study of sequential IV/oral ciprofloxacin therapy versus ceftazidime for the treatment of nosocomial pneumonia. Although nearly half of the ciprofloxacin patients received sequential therapy, the majority were treated with a full IV regimen. Clinical success rates and antibiotic-related adverse events were similar for the ciprofloxacin and ceftazidime groups. Per patient and per day costs of antibiotic acquisition; preparation and administration; treatment of adverse events, and clinical failures were compared. Decision analysis revealed that ciprofloxacin therapy was cost-effective compared to ceftazidime 2 g q8h. Varying the probability of clinical success between 60-99% failed to change the economic decision; costs for ciprofloxacin were always lower than for ceftazidime. Further sensitivity analyses demonstrated that if the ceftazidime price was reduced by 50% (equivalent to 1 g q8h), treatment costs would be similar to ciprofloxacin therapy. Increasing the ciprofloxacin price by 50% (equivalent to a q8h frequency) produced per patient costs similar to ceftazidime, although ciprofloxacin therapy retained a lower cost per day (p < 0.0002). For the treatment of nosocomial pneumonia, ciprofloxacin therapy was cost-effective compared to ceftazidime.
