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)

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".

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.
