Calculate CMAM length of stay and median length of stay for a cohort of CMAM discharges

Usage

calculate_los(admission_date, discharge_date)

calculate_los_median(admission_date, discharge_date, group = NULL)

Arguments

admission_date: Date of admission in YYYY-MM-DD format. If child is a kwashiorkor case, date of lowest weight (when oedema has subsided). Can be a single date value or a vector of date values.
discharge_date: Date of discharge in YYYY-MM-DD format. Can be a single date value or a vector of date values.
group: A character value/s with the same length as admission_date and discharge_data to use as grouping variable within which median length-of-stay is to be calculated. Default is NULL for no grouping.

Value

Numeric value or vector of numeric values for length-of-stay in days for calculate_los(). A numeric value for median length-of-stay in days for calculate_los_median(). If group is not NULL, a vector of numeric values for median length-of-stay in days with length equal to the number of groups.
