Trauma-08 Populations
Description
Filters data down to the target populations for Trauma-08, and categorizes records to identify needed information for the calculations.
Identifies key categories to records that are 911 requests for patients with trauma during which GCS, systolic blood pressure, and respiratory rate are documented based on specific criteria and calculates related ECG measures. This function segments the data by age into adult and pediatric populations.

a tibble with counts for each filtering step,
a tibble for each population of interest
a tibble for the initial population
a tibble for the total dataset with computations
