RESECT-90 Score for Lung Resection Mortality

Description

Calculates the RESECT-90 score to estimate the 90-day risk of mortality in patients undergoing lung resection (e.g., lobectomy, pneumonectomy). The model is a multivariable logistic regression derived from a large UK cohort (Taylor et al., 2021). It incorporates patient demographics, comorbidities, and surgical factors.

Usage

resect90_lung_mortality_score(age, sex, ecog_ps, dlco_percent, bmi, creatinine,
                              anemia, arrhythmia, right_sided_resection,
                              thoracotomy_approach, malignant_diagnosis,
                              num_resected_segments, creatinine_units = "mg/dL")

Arguments

age	Numeric. Patient age in years.
sex	String. "Male" or "Female". (Male sex is associated with higher risk).
ecog_ps	Numeric. Eastern Cooperative Oncology Group (ECOG) performance status (0-4).
dlco_percent	Numeric. Percentage predicted diffusion capacity of the lung for carbon monoxide (DLCO).
bmi	Numeric. Body Mass Index in kg/m^2. (Higher BMI is associated with lower risk in this model).
creatinine	Numeric. Serum creatinine level.
anemia	Numeric (0 or 1). Presence of preoperative anemia. (1 = Yes).
arrhythmia	Numeric (0 or 1). History of preoperative arrhythmia (e.g., Atrial Fibrillation). (1 = Yes).
right_sided_resection	Numeric (0 or 1). Is the surgery a right-sided resection? (1 = Yes).
thoracotomy_approach	Numeric (0 or 1). Is the surgery performed via open thoracotomy (vs VATS/Robotic)? (1 = Yes).
malignant_diagnosis	Numeric (0 or 1). Is the resection for a malignant diagnosis? (1 = Yes).
num_resected_segments	Numeric. Number of bronchopulmonary segments resected (e.g., Lobectomy ~3-5, Pneumonectomy ~10).
creatinine_units	String. Units for creatinine. "mg/dL" (default) or "umol/L".

Value

A list containing:

RESECT90_Score_Percent	The estimated percentage probability of death within 90 days of surgery.
Interpretation	Brief context for the result.
