I read a little more about the blood culture biofire that we’ve started seeing – BCID2 – 43 PCR results including organisms and resistance – https://www.biofiredx.com/products/the-filmarray-panels/filmarraybcid/ and some evidence – Banerjee et al randomized 617 patients with positive blood cultures to usual care (takes about two days to get results from micro lab cultures) vs BCID +- stewardship team – showed shorter time to organism identification and appropriate abx changes – no difference in mortality, LOS, or cost
https://academic.oup.com/cid/article/61/7/1071/289120 They also have a small number of discrepancies (11 cases) in their Table 2 – but pretty reasonable and only 3 true cases of organism identification discrepancy
I’m excited to see this and look forward to using it clinically!
