hypoglycemia_01: Hypoglycemia-01

Description

The hypoglycemia_01 function calculates the NEMSQA measure evaluating how often hypoglycemic patients with altered mental status receive hypoglycemia treatment.

  ...
)

Value

A data.frame summarizing results for two population groups (All, Adults and Peds) with the following columns:

• pop: Population type (All, Adults, and Peds).

• numerator: Count of incidents meeting the measure.

• denominator: Total count of included incidents.

• prop: Proportion of incidents meeting the measure.

• prop_label: Proportion formatted as a percentage with a specified number of decimal places.

• lower_ci: Lower bound of the confidence interval for prop (if confidence_interval = TRUE).

• upper_ci: Upper bound of the confidence interval for prop (if confidence_interval = TRUE).

Arguments

df

A data frame or tibble containing emergency response records. Default is NULL.

patient_scene_table

A data.frame or tibble containing at least ePatient and eScene fields as a fact table. Default is NULL.

response_table

A data.frame or tibble containing at least the eResponse fields needed for this measure's calculations. Default is NULL.

situation_table

A data.frame or tibble containing at least the eSituation fields needed for this measure's calculations. Default is NULL.

vitals_table

A data.frame or tibble containing at least the eVitals fields needed for this measure's calculations. Default is NULL.

medications_table

A data.frame or tibble containing at least the eMedications fields needed for this measure's calculations. Default is NULL.

procedures_table

A data.frame or tibble containing at least the eProcedures fields needed for this measure's calculations. Default is NULL.

erecord_01_col

Column representing the unique record identifier.

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

Column representing the patient's numeric age agnostic of unit.

epatient_16_col

Column representing the patient's age unit ("Years", "Months", "Days", "Hours", or "Minute").

eresponse_05_col

Column containing response type codes.

esituation_11_col

Column for primary impression fields, containing ICD-10 codes.

esituation_12_col

Column for secondary impression fields, containing ICD-10 codes.

evitals_18_col

Column for blood glucose levels.

evitals_23_col

Column for Glasgow Coma Scale (GCS) scores.

evitals_26_col

Column for AVPU alertness levels.

emedications_03_col

Column for administered medications.

eprocedures_03_col

Column for procedures performed.

confidence_interval

Logical. If TRUE, the function calculates a confidence interval for the proportion estimate.

method

Character. Specifies the method used to calculate confidence intervals. Options are "wilson" (Wilson score interval) and "clopper-pearson" (exact binomial interval). Partial matching is supported, so "w" and "c" can be used as shorthand.

conf.level

Numeric. The confidence level for the interval, expressed as a proportion (e.g., 0.95 for a 95% confidence interval). Defaults to 0.95.

correct

Logical. If TRUE, applies a continuity correction to the Wilson score interval when method = "wilson". Defaults to TRUE.

...

optional additional arguments to pass onto dplyr::summarize.
