PMID 39319964WHAT IT FOUND
High Tuman Score risk was linked to pulmonary and neurological complications after cardiac surgery, but not to cardiac or infectious complications; most of 70 patients were low risk.
Key findings
01Of 70 selected cardiac surgical procedures, 41 (58.57%) were low risk, 27 (38.57%) moderate risk, and 2 (2.85%) high risk on the Tuman Score.
02High Tuman Score risk was associated with pulmonary complications (relative risk 1.32, p=0.002) and neurological complications (relative risk 1.20, p=0.047) compared with low risk.
03Cardiac complications were the most frequent postoperative events (n=16), followed by infection (n=6), but the high-risk cardiac relative risk of 1.65 was not confirmed (p=0.625).

What it does not show
The study was small and non-probabilistic: 70 selected cardiac surgical procedures, and only 2 patients were high risk. It was retrospective and record-based at one university hospital, so it cannot show that the score causes or prevents complications. The authors state the sample was reduced by the COVID-19 pandemic and suspension of elective procedures. The high-risk group was very small, so the pulmonary and neurological associations need cautious interpretation.
The easy way to misread this
Do not conclude that using the Tuman Score prevents complications or that it predicts cardiac complications after cardiac surgery. The study was observational, only 2 patients were high risk, and the high-risk cardiac complication association was not significant (p=0.625).
