Methods
a- Data collection
This is a retrospective cohort study; we conducted a chart review of all
adults (18 years or more) patients diagnosed with HPMV admitted to our
hospital in 2017.
Demographics, clinical, laboratory, radiographic, treatments and outcome
data were collected at the time of admission or the time when the
multiplex PCR was taken for patients who developed the infection during
hospitalization. The Charlson Comorbidity Index scores were calculated
for every patient.
b- Statistical analysis
Collected data are summarized using descriptive statistics, mean median
and standard deviation for continuous variables, and numbers and
percentages for categorical variables. To assess if there is significant
relationship between two categorical variables among survivors and non
survivors, we used X2 and Fisher exact test analysis while for
continuous variables we used the Student T test analysis. A p- value
less than 0.05 was considered significant.
