[Study of the cost-effectiveness of sequential antibiotic (ciprofloxacin) therapy].

A multicenter, prospective, randomized study was performed to compare the cost-effectiveness of parenteral antibiotic versus parenteral antibiotic + oral ciprofloxacin sequential therapy in the treatment of moderate and severe infections in hospitalized patients. After deciding on inclusion (n = 298), the patients were randomly allocated in group "A" (evaluable 120 cases) receiving only parenteral antibiotics, or in group "B" receiving parenteral antibiotic + oral ciprofloxacin from the 3.-5. day of therapy on. The local physician decided on the starting parenteral therapy and the necessity of other therapeutic interventions, and in case of group "B" patients on the possibility of switching parenteral to oral therapy. The overall cure rate was 68% in group "A" and 82% in group "B" (improved 33 and 21, failure 5 and 1 cases resp.). Of the direct costs in patients, care, the costs of antibiotic treatments based on purchase prices was compared: the cost of antibiotic treatment in group "B" was 32% less than in group "A", and the sequential therapy saved 9000 Ft/patient in average. In conclusion, ciprofloxacin proved to be an effective antimicrobial agent that can also be used in sequential therapy and the oral administration resulted in a significant save of money with the same therapeutic effectiveness.
