Costs and benefits of diagnostic and therapeutic methods in Salmonella infections
Abstract:
Type and number of specific diagnostic procedures; type, time and exitus of therapy were studied in the management of 335 hospitalized patients with Salmonella infection during a nine/years period (1976-1984). Sixty-three cases of S. typhi (18.8%), 26 of S. paratyphi B (7.7%), 48 of S. typhimurium (14.3%) and 198 other Salmonella species (59.1%) were identified. Positive cultures were obtained from blood in 18.8% of cases. In typhoid fever bacteriemia was detected in 60.3% of cases. The sensitivity of microorganisms to antibiotics was detected. Of 281 (83.8%) patients treated with "major" antibiotics (CAF, Ampicillin or Co-trimoxazole) clearance of Salmonella was obtained in 171 (60.8%). Stool "acidification" with lactulose was attempted in 54 patients (16.2%), of which 20 (37%) became negative. Charges of the bacteriologic cultures, serological tests, antibiotics and supportive therapy were estimated in order to assess the cost/benefit ratio of patients care. Length of stay and chemotherapy were respectively 20.7 (11-18) and 11 (7-17) days. Maximal cost/case ratio occurs in diagnosis for stool cultures, in therapy for Ampicillin. The introduction of an economic approach to use diagnostic and therapeutic procedures has significantly improved the management of Salmonella infections from 1976 to 1984.
Insights
This study analyzed Salmonella infection management in 335 patients. An economic approach to diagnostics and therapeutics significantly improved Salmonella infection care between 1976 and 1984.
Area of Science:
- Infectious Diseases
- Medical Microbiology
- Health Economics
Background:
- Salmonella infections pose a significant public health challenge.
- Effective management strategies are crucial for reducing morbidity and mortality.
- Understanding the cost-effectiveness of diagnostic and therapeutic interventions is vital for optimizing patient care.
Purpose of the Study:
- To evaluate the diagnostic procedures and therapeutic interventions used in managing hospitalized Salmonella infections.
- To assess the cost-benefit ratio of various diagnostic and therapeutic approaches.
- To determine the impact of an economic approach on Salmonella infection management over a nine-year period.
Main Methods:
- Retrospective analysis of 335 hospitalized patients with Salmonella infection (1976-1984).
- Categorization of Salmonella species, including S. typhi, S. paratyphi B, S. typhimurium, and others.
- Evaluation of diagnostic methods (blood cultures, stool cultures), antibiotic sensitivity, and therapeutic outcomes (antibiotic treatment, lactulose acidification).
- Estimation of costs associated with bacteriologic cultures, serological tests, antibiotics, and supportive therapy.
Main Results:
- Salmonella species identified included S. typhi (18.8%), S. paratyphi B (7.7%), S. typhimurium (14.3%), and others (59.1%).
- Blood cultures were positive in 18.8% of cases; bacteremia in typhoid fever was 60.3%.
- Antibiotic treatment (e.g., Ciprofloxacin, Ampicillin, Co-trimoxazole) achieved Salmonella clearance in 60.8% of patients.
- Stool acidification with lactulose resulted in negative cultures in 37% of treated patients.
- Maximal cost/case ratio was observed for stool cultures in diagnostics and Ampicillin in therapy.
- Average length of hospital stay was 20.7 days, with an 11-day chemotherapy duration.
Conclusions:
- The implementation of an economic approach to diagnostic and therapeutic procedures significantly improved the management of Salmonella infections.
- Cost-effectiveness analysis is essential for optimizing resource allocation in infectious disease management.
- Further research into cost-effective diagnostic and treatment strategies for Salmonella infections is warranted.
