gupta_mica_risk: Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA)

Description

Calculates the percentage risk of perioperative Myocardial Infarction (MI) or Cardiac Arrest (MICA) within 30 days of surgery. This model was derived from the NSQIP database and provides a site-specific risk assessment based on five preoperative predictors.

Usage

gupta_mica_risk(age, creatinine_mg_dl, asa_class, functional_status,
                procedure_type)

Value

A list containing:

MICA_Risk_Percent

The estimated percentage risk of perioperative MI or Cardiac Arrest.

Inputs

A record of the parameters used for the calculation.

Arguments

age

Numeric. Patient age in years.

creatinine_mg_dl

Numeric. Preoperative serum creatinine in mg/dL.

asa_class

Numeric (1-5). American Society of Anesthesiologists Physical Status Classification. 1: Normal healthy patient. 2: Mild systemic disease. 3: Severe systemic disease. 4: Severe systemic disease that is a constant threat to life. 5: Moribund.

functional_status

String. Preoperative functional status. Options: "independent", "partially_dependent", "totally_dependent".

procedure_type

String. Surgical site/category. Valid options include: "anorectal", "aortic", "bariatric", "brain", "breast", "cardiac", "ent", "foregut_hepatopancreatobiliary", "gallbladder_appendix_adrenal_spleen", "hernia_ventral_inguinal", "intestinal", "neck_thyroid_parathyroid", "obgyn", "ortho_non_spine", "spine", "thoracic_non_cardiac", "urology", "vascular_non_aortic", "vein".
