Description of intervention(s) / exposure
This study will determine the factors which are associated with adverse clinical outcomes in patients who are hospitalised due to seasonal influenza and will study association of troponin levels with clinical outcomes in patients with influenza. The troponin levels done at any time during the index admission will be assessed. The clinical outcomes observed will include length of hospital stay (LOS),in-hospital mortality, complications during index admission and number of readmissions within one and six months of hospital discharge.

Statistical methods / analysis
Values will be presented as mean (standard deviation) or median (interquartile range) for
continuous variables and as number (percentage) for categorical variables where
appropriate. Student’s t test or MannWhitney test will be used to compare continuous
variables while Chi2 or Fisher’s exact test will test categorical variables as
appropriate. Multivariate logistic regression will be used to determine whether troponin
elevation during hospital admission predicts length of hospital stay, mortality,
complications during hospital admission or readmissions within one month or within 6
months following discharge after adjusting for confounders including age, gender, Charlson
index and preexistingcardiovascular disease.
Kaplan-Meier survival curves will be plotted and Log rank test will be used to determine
differences in survival according to troponin elevation during admission. All tests of
significance will be two-tailed and a p < 0.05 will be considered as statistically
significant.
