calculate_dcs_1993_risk_factor_index: Calculate The Risk Factor Index For Duke Clinical Score 1993

Description

A function used to calculate the patient's risk factor index. This is used to calculate the likelihood of severe coronary artery disease in the Duke Clinical Score 1993 paper.

Usage

calculate_dcs_1993_risk_factor_index(
  have_hypertension,
  have_dyslipidemia,
  have_diabetes,
  max_na = 0,
  label_have_hypertension_no = c("no"),
  label_have_hypertension_yes = c("yes"),
  label_have_hypertension_unknown = c(NA, NaN),
  label_have_dyslipidemia_no = c("no"),
  label_have_dyslipidemia_yes = c("yes"),
  label_have_dyslipidemia_unknown = c(NA, NaN),
  label_have_diabetes_no = c("no"),
  label_have_diabetes_yes = c("yes"),
  label_have_diabetes_unknown = c(NA, NaN),
  error_call = rlang::caller_env()
)

Value

An integer indicating the patient's risk factor index. It can also be NA if the number of missing risk factors exceeds the max_na

input value.

Arguments

have_hypertension

The value of variable in the parameters label_have_hypertension_no, label_have_hypertension_yes and label_have_hypertension_unknown.

have_dyslipidemia

The value of variable in the parameters label_have_dyslipidemia_no, label_have_dyslipidemia_yes and label_have_dyslipidemia_unknown.

have_diabetes

The value of variable in the parameters label_have_diabetes_no, label_have_diabetes_yes and label_have_diabetes_unknown.

max_na

Input integer 0 to 3 to indicate the maximum number of missing risk factors to tolerate before outputting an NA. Default: 0

label_have_hypertension_no

Label(s) for patient with no hypertension. Default: c("no")

label_have_hypertension_yes

Label(s) for patient having hypertension. Default: c("yes")

label_have_hypertension_unknown

Label(s) for patient having unknown hypertension. Default: c(NA, NaN)

label_have_dyslipidemia_no

Label(s) for patient with no dyslipidemia. Default: c("no")

label_have_dyslipidemia_yes

Label(s) for patient having dyslipidemia. Default: c("yes")

label_have_dyslipidemia_unknown

Label(s) for patient having unknown dyslipidemia. Default: c(NA, NaN)

label_have_diabetes_no

Label(s) for patient with no diabetes. Default: c("no")

label_have_diabetes_yes

Label(s) for patient having diabetes. Default: c("yes")

label_have_diabetes_unknown

Label(s) for patient having unknown diabetes. Default: c(NA, NaN)

error_call

The execution environment of a currently running function, e.g. caller_env(). The function will be mentioned in error messages as the source of the error. See the call argument of abort() for more information.

Examples
