Key result
The P-POSSUM scoring system effectively predicted postoperative mortality (predicted 4.2% vs actual 6.6%; P=0.055 for lack of fit), whereas POSSUM significantly overpredicted risk (14.2%; P=0.003).
Why the study?

Does the P-POSSUM scoring system accurately predict postoperative mortality in Chinese patients undergoing major hepatectomy for hepatocellular carcinoma compared to the POSSUM system?
Absolute Event Rate: 4.2% vs 6.6%
p-value: p=0.055
The P-POSSUM scoring system accurately predicts postoperative mortality in Chinese patients undergoing major hepatectomy for hepatocellular carcinoma, whereas the POSSUM system significantly overpredicts risk.
Fan et al. (2004) conducted an observational in Hepatocellular carcinoma (n=259). P-POSSUM and POSSUM scoring systems vs. Actual postoperative mortality was evaluated on Postoperative mortality (p=0.055). The P-POSSUM scoring system effectively predicted postoperative mortality (predicted 4.2% vs actual 6.6%; P=0.055 for lack of fit), whereas POSSUM significantly overpredicted risk (14.2%; P=0.003).
