Clinical and economic effect of ciprofloxacin as an alternative to injectable antimicrobial therapy.
The effect of the use of oral ciprofloxacin on patient outcome and the cost of antimicrobial therapy was investigated. In 1988 ciprofloxacin was placed on the antimicrobial formulary at a Veterans Affairs medical center. Patients with urinary tract infections, soft tissue infections, osteomyelitis, or pneumonia due to organisms that were documented as being susceptible to ciprofloxacin and either resistant to other oral antimicrobials or susceptible to other oral antimicrobials in patients allergic to such agents were monitored in a prospective open study over 12 months. When a patient was enrolled, the physician was asked to select the i.v. antimicrobial regimen that would have been used if ciprofloxacin were not available. Patient outcome was determined from medical records, and the difference in the costs of the oral and i.v. regimens was calculated. Clinical cure occurred in 96/100 (96%) of patients with urinary tract infection, 19/22 (86%) with soft tissue infection, 14/16 (88%) with osteomyelitis, and 10/12 (83%) with pneumonia. The overall cure rate was 139/150 (93%). The 11 clinical failures occurred in patients infected with methicillin-resistant Staphylococcus aureus (MRSA) alone, group D enterococcus alone, MRSA and Pseudomonas sp., and Pseudomonas sp. alone. The total cost avoidance achieved by using oral ciprofloxacin instead of i.v. antimicrobials was $77,158. Oral ciprofloxacin was an effective and cost-efficient alternative to traditional i.v. antimicrobial therapy in the patients studied.
