respiratory_02_population: Respiratory-02 Populations

Description

The respiratory_02_population function calculates metrics for pediatric and adult respiratory populations based on pre-defined criteria, such as low oxygen saturation and specific medication or procedure codes. It returns a summary table of the overall, pediatric, and adult populations, showing counts and proportions.

Usage

respiratory_02_population(
  df = NULL,
  patient_scene_table = NULL,
  response_table = NULL,
  vitals_table = NULL,
  medications_table = NULL,
  procedures_table = NULL,
  erecord_01_col,
  incident_date_col = NULL,
  patient_DOB_col = NULL,
  epatient_15_col,
  epatient_16_col,
  eresponse_05_col,
  evitals_12_col,
  emedications_03_col,
  eprocedures_03_col
)

Value

A list that contains the following:

• 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

Arguments

df

A data frame containing incident data with each row representing an observation.

patient_scene_table

A data.frame or tibble containing at least epatient and escene fields as a fact table.

response_table

A data.frame or tibble containing at least the eresponse fields needed for this measure's calculations.

vitals_table

A data.frame or tibble containing at least the evitals fields needed for this measure's calculations.

medications_table

A data.frame or tibble containing only the emedications fields needed for this measure's calculations.

procedures_table

A data.frame or tibble containing only the eprocedures fields needed for this measure's calculations.

erecord_01_col

Column name for eRecord.01, used to form a unique patient ID.

incident_date_col

Column that contains the incident date. This defaults to NULL as it is optional in case not available due to PII restrictions.

patient_DOB_col

Column that contains the patient's date of birth. This defaults to NULL as it is optional in case not available due to PII restrictions.

epatient_15_col

integer Column giving the calculated age value.

epatient_16_col

Column giving the provided age unit value.

eresponse_05_col

Column name for response codes (e.g., incident type).

evitals_12_col

Column name for oxygen saturation (SpO2) values.

emedications_03_col

Column name for medication codes.

eprocedures_03_col

Column name for procedure codes.
