Summary

Silicosis, a preventable yet irreversible occupational lung disease, has an insidious onset with a latency period for diagnosis extending beyond 10 years from the initial exposure. The central hypothesis of this study is that silicosis cases may currently be going undetected. The long-term goal of this research is to determine the current prevalence and forecast the future prevalence of silicosis and other pneumoconiosis among working populations in Oklahoma and to assist the public health and the healthcare system in planning for a potential resurgence of silicosis.

Conditions

• Silicosis
• Pneumoconiosis; Silica

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Tuberculosis test	Tuberculosis (TB) test: A blood sample is collected for lab testing to determine if you have tuberculosis (QuantiFeron test). Alternatively, the test is done by injecting a small amount of fluid (called tuberculin) into the skin on the lower part of the arm. A person given the tuberculin skin test must return within 48 to 72 hours to have a trained health care worker look for a reaction on the arm.
DIAGNOSTIC_TEST	Chest X-ray	Chest X ray: non-invasive medical test that helps physicians diagnose and treat medical conditions of the lungs and chest. The Chest X-ray will be done to check for abnormalities on the lungs. The test is non-invasive.
DIAGNOSTIC_TEST	Pulmonary Function Test	A pulmonary function test (PFT, spirometry) is a breathing test that measures how much air your lungs can hold as well as how hard and fast you can blow air out of your lungs. The test is not invasive and involves blowing into a machine.
