Hypothesis
Cost-effectiveness comparisons of various diagnostic options for Pneumocystis pneumonia have not been presented.
Conclusion
PCR technologies combined with less-invasive specimen collection methods are more cost-effective for diagnosing Pneumocystis pneumonia than more invasive methods.
Supporting Evidence
- Diagnostic procedures using expectorated sputum with PCR methods successfully treated 77-90% of patients.
- Procedures using bronchoalveolar lavage were significantly more expensive without added benefit.
- A cost-effective diagnostic procedure that did not require PCR was Toluidine Blue O staining of induced sputum.
Takeaway
This study looked at different ways to test for a lung infection called Pneumocystis pneumonia and found that some tests are cheaper and work better than others.
Methodology
The study compared cost-effectiveness of 33 diagnostic options using various specimen collection methods and laboratory procedures.
Potential Biases
The degree of experience of clinicians could affect test sensitivity and specificity.
Limitations
Data on sensitivity and specificity for all diagnostic procedures were not available, requiring some estimates; indirect costs were not included.
Participant Demographics
Ambulatory HIV-infected patients in South Africa.
