Brief summary
P-POSSUM score had a predictive power of \>80% to predict the length of stay of kidney transplant recipients
Interventions
OTHERPortsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM) score
P-POSSUM score's variables are divided into physiological parameters (age, cardiac, respiratory, ECG, systolic blood pressure, pulse rate, haemoglobin, leukocyte count, urea, sodium plasma, potassium plasma, and GCS) and operative parameters (operation type, number of procedures, operative blood loss, peritoneal contamination, malignancy status, CEPOD).
