Division of Chest and Critical Care

The Division of Chest and Critical Care provides expert care for a broad spectrum of pulmonary disease and sleep issues. Our pulmonary specialists diagnose and manage benign and malignant conditions, including thromboembolic disease, interstitial lung disease, and pulmonary hypertension. Our intensivists also provide 24/7 in-house coverage at Scripps hospitals, serving adult medical-surgical ICU populations including transplants, cardiothoracic surgery, neurology/neurosurgery, and level 1 trauma. A number of our pulmonologists work in collaboration with the Oncology Division to diagnose and treat lung cancer, including interventional pulmonology.

We also work with patients suffering from sleep disorders of varying complexities. Our team is on staff at the Viterbi Family Sleep Center, one of the nation’s most historied sleep centers, where they provide multidisciplinary care dedicated to comprehensive diagnosis and management of all sleep disorders. Our practitioners offer extensive home and inpatient diagnostics to identify and, where possible, begin to treat, sleep apnea, insomnia, restless legs syndrome (RLS), and other neurologically-based sleep issues such as narcolepsy and circadian rhythm abnormalities. We also provide non-invasive ventilator support for patients with chronic respiratory failure, particularly in the setting of neurologic or neuromuscular disorders.

Our Division has a robust academic program. We have weekly conferences encompassing evidence-based literature review, and case reviews to help advance patient care to the highest level possible. We have developed co-management conferences with other divisions, such as Hepatology, Transplant, Trauma, Cardiology and Palliative care. Due to our multidisciplinary engagement we have developed protocols addressing complex clinical situations that have been adopted system wide.

Some of our faculty hold teaching positions at UCSD and Scripps Research. Our Division members are active in professional societies and hold leadership positions at American Thoracic Society, California Thoracic Society and National Association for Medical Direction of Respiratory Care.

The clinical and translational research projects of the Division of Pulmonary and Critical Care Medicine encompass a group of studies in pulmonary and interventional pulmonary medicine. 

Minimally invasive pulmonary procedures are increasingly recognized as the current standard of care for diagnosing lung cancer and a variety of nonmalignant lung diseases. The creation of a clinical database as a resource to promote quality assurance, control and guide future directions of types of procedures performed and offered.  

The Scripps Venous Thrombosis Registry cohort has plasma and DNA specimens collected from over 110 patients and 220 controls which are the basis of scientific collaborations with Scripps Research. The purpose is the discovery of novel procoagulant factors and which have the potential to guide new therapies for patient care. 

Pulmonary Embolism Outcomes Research started as an assessment of hospital-based treatment and has extended to ambulatory management of acute low risk pulmonary embolism patients. Clinical assessment for low risk patients has the goal to improve care of patients with acute pulmonary embolism.

Interstitial lung disease (ILD) is an increasingly recognized inflammatory condition of the lung which causes permanent fibrosis and respiratory insufficiency. A clinical database is being used as a resource to promote analysis of the clinical characteristics, diagnosis patterns, treatments and outcomes of the ILD patient population at Scripps Clinic.
