Background:
Lung cancer (LC) is a leading cause of cancer mortality in Argentina. Low-dose computed tomography (LDCT) had demonstrated higher efficacy than chest radiography as a screening method for early detection and reducing LC mortality. This study estimates the Budget Impact of implementing annual LDCT screening for individuals aged 55-74 with at least 30 pack-years of smoking in Argentina.
Research Design And Methods:
A budgetary impact model for a dynamic cohort was developed from the Argentine health system's perspective, accounting for LC incidents, prevalents and death probability, distinguishing by disease stage and survival years. Model parameters were sourced from literature and official databases, with costs expressed in 2023 USD.
Results:
In Argentina, 726,420 individuals were eligible for annual LC screening. The average annual budget was USD 196,611,452 in the current scenario and USD 207,439,560 in the projected scenario, leading to a 5.20% incremental cost due to more false positives in LDCT and screening costs. The budget impact per member per month was USD 0.019, slightly above the estimated threshold of USD 0.015.
Conclusions:
The introduction of LDCT for LC screening increased the health system budget in Argentina but improved early disease detection.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
