First up, I presented the National Comparative Audit of transfusion associated circulatory overload. There is more to TACO than perhaps meets the eye; good
review article here onlinelibrary.wiley.com/doi/full/10.11…
ISBT revised the definition of TACO in March 2019 (which remains a clinical diagnosis) - paper is here
isbtweb.org/fileadmin/user…
Onset during or up to 12 hours after transfusion (SHOT up to 24h)
≥1 required criterion AND ≥3 criteria i.e. A and/or B, and total of at least 3 of A to E
Required criteria
A. Acute or worsening respiratory compromise
B. Evidence of acute or worsening pulmonary oedema 1/
Additional criteria
C. Cardiovascular system changes (htn, tachycardia, hypertension, pulm oedema)
D. Fluid overload (+ve fluid balance; clinical improvement following diuresis)
E. Positive biomarker (e.g. BNP or NT-pro BNP) 2/2
In the audit 89% of patients aged >60 had at least 1 additional risk factor for TACO. For such a common problem, there are very little data to support appropriate action to take in patients with risk factors.
Results of the NCA can be found here

Suffice to say, we could do better at assessing risk, monitoring and treating appropriately!
