Key result
A pre-operative neutrophil lymphocyte ratio ≥22 independently predicted 30-day mortality after emergency abdominal surgery in patients aged 80 years or older (p=0.004).

Does pre-operative neutrophil lymphocyte ratio predict mortality in elderly patients undergoing emergency abdominal surgery?
p-value: p=0.004
Pre-operative neutrophil lymphocyte ratio is a simple, easily calculable prognostic marker for short- and long-term mortality in elderly patients undergoing emergency abdominal surgery.
Vaughan-Shaw et al. (2012) conducted an observational in Emergency abdominal surgery (n=172). Neutrophil lymphocyte ratio (N/L ratio) was evaluated on 30-day mortality (p=0.004). A pre-operative neutrophil lymphocyte ratio ≥22 independently predicted 30-day mortality after emergency abdominal surgery in patients aged 80 years or older (p=0.004).
