The RSV Global Respriatory Severity Score (GRSS) app is an interactive tool to compute a severity score based upon method in Caserta, et.al., 2017.
for full citation and definition of input parameters. As values are entered, the score is dynamically computed.
Disclaimer: The score is for research purposes only and not for making diagnosis or clinical decisions. The score is valid for primary RSV infections among full term infants less than 10 months of age and otherwise healthy.

Variables used in this score
Please see table below for the list of 10 variables used in the calculation, along with their data type, \(\beta\) values and mean values used in the calculation (See other sections below for details).
Mean imputation of Missing Values
For subjects with missing values, we use mean imputation to substitute NA values. Here “mean” refers to the mean values obtained from our study and these values are recorded in column 5 of the above table.
Adjusted Respiratory Rate
The maximum respiratory rate needs to be adjusted by the following formula \(Adjusted Resp. Rate = Resp. Rate - (0.8 * Age)\)
