gupta_pneumonia_risk: Gupta Postoperative Pneumonia Risk

Description

Calculates the percentage risk of developing postoperative pneumonia based on the Gupta et al. (2013) model derived from the NSQIP database. This calculator is designed for adult patients undergoing non-cardiac and cardiac surgeries.

Usage

gupta_pneumonia_risk(age, copd, functional_status, asa_class, sepsis_status,
                     smoker, procedure_type)

Value

A list containing:

Pneumonia_Risk_Percent

The estimated probability of postoperative pneumonia.

Arguments

age

Numeric. Patient age in years.

Numeric. ASA Physical Status Classification (1-5).

sepsis_status

String. Preoperative sepsis category. Options: "none", "sirs" (Systemic Inflammatory Response Syndrome), "sepsis", "septic_shock".

smoker

Numeric (0 or 1). Current smoker (within 1 year). (1 = Yes).

procedure_type

String. Surgical procedure 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", "orthopedic", "other_abdominal", "peripheral_vascular", "skin", "spine", "thoracic_non_cardiac", "urology", "vein".
