This is a fascinating study which adds a whole new dimension to the issue of improving diagnostic accuracy. It shows how important diagnostic accuracy is to appropriate antimicrobial (AM) therapy.
Key facts that jumped out were that:
1. Initial provider diagnosis was considered correct in only 55% of cases
2. When the initial diagnosis was correct the AM therapy was considered appropriate in 62% of cases. When the initial diagnosis was incorrect, uncertain, or a sign or symptom then the AM was only appropriate in 11% of cases. This completely blows away the idea that often it doesn't matter if the diagnosis is not made or correct as the treatment would be the same anyway.
3. Overall across the 500 cases, the diagnosis was not correct in 163 (33%) of cases and in only 13 of those cases was the AM therapy appropriate.
4. The authors stated that "the study confirmed the tremendous impact of diagnostic accuracy on AM appropriateness"
This study set out to look at whether AM appropriateness improved when CDSS was used but on the assumption that the initial diagnosis was correct. What they found instead was that dx accuracy had much more impact on AM appropriateness rather than the use of therapy CDSS.
This study helps show the tremendous impact diagnostic accuracy has on not just AM therapy but on so many crucial aspects of healthcare. It shows the complete futility of trying to improve healthcare without improving diagnosis, the first and most important decision made about the patient.
