WelcomePulmonary Critical Care & Sleep Medicine (PCCSM)

The Division of Pulmonary Critical Care & Sleep Medicine is to dedicated to the prevention and treatment of respiratory diseases, and through our clinical, educational, and research missions, we hope to achieve these goals.

The clinical mission of our Division is to provide comprehensive diagnosis and management for a broad range of respiratory diseases, to offer outstanding clinical care for patients with respiratory disorders, and to serve as a resource to regional physicians who share in the care of patients with respiratory diseases. We offer comprehensive outpatient services on the UTMB main campus and the Texas mainland. Our three sleep laboratories are located on the main campus, with another convenient center in Webster, and our third location at the Angleton Danbury hospital. Our inpatient services include pulmonary consultations, and critical care services delivered in our medical and surgical intensive care units (ICUs).

We offer broad based expertise in respiratory diseases, chronic obstructive pulmonary disease (COPD; emphysema and chronic bronchitis), lung cancer, lung infections, pulmonary fibrosis, and pulmonary hypertension. Diagnostic services include a comprehensive pulmonary function laboratory, including exercise capability, a modern and well-equipped suite for flexible bronchoscopy, and three sleep laboratories.

The educational mission of our Division includes Accreditation Council for Graduate Medical Education (ACGME)-accredited fellowship programs and Pulmonary and Critical Care Medicine), medical student teaching, internal medicine resident instruction, and a commitment to the continuing medical education (CME) of our regional physician partners.

The research mission of the Division of Pulmonary Critical Care & Sleep Medicine is to develop new knowledge in fields related to respiratory diseases that will improve quality of care and healthcare outcomes.

Congratulations to Drs. Raji & Kuo (Co-Principal Investigators) Receive $1.42M in Second Round of Funding “2 R01 DA039192-05” from National Institute on Drug Abuse | NIH Budget Period: 07/01/2020 – 04/30/2024

In 2016, the Centers for Disease Control and Prevention (CDC) issued guidelines for “all prescribers to avoid co-prescribing of benzodiazepine (benzo) and opioids”; other guidelines also advised against benzos for anxiety and insomnia because safer substitutes exist. Since the 2016 CDC guideline, use of gabapentinoids as an opioid substitute has risen. While recent data showed a decline in opioid prescribing rates after publication of the CDC guideline, a knowledge gap exists in terms of the rates, effectiveness and safety of opioid/benzo substitute prescribing and co-prescribing, especially in populations at high risk of drug toxicity: persons living with disabilities, the elderly and Medicare enrollees in home health care. Neither opioid nor benzo substitutes (gabapentinoids, Z-drugs, SNRIs and SSRIs) alone or in combination have been studied in these populations. Dr. Raji & Dr. Kuo will use both 20% national Medicare data and a large commercial health insurance database to study the effectiveness and safety of the substitutes, whether the substitutes improve pain and function, and whether they have fewer toxicities. Our overall hypotheses is that the substitute drugs, alone or in combination, have considerably lower rates of serious toxicity than do opioids and benzos, with similar effectiveness in many clinical situations. If this is the case, its demonstration by our proposed research should result in acceleration in the shift away from opioids and benzos to safer alternatives.

Welcome to the Division of Pulmonary Critical Care & Sleep Medicine.

We are committed to value based, patient-centered and outcomes-driven care. Our diverse clinical expertise will serve the needs of patients with acute and chronic lung conditions.

The Division has a longstanding tradition of training the next generation of pulmonary and critical care medicine physicians. We are proud of our alumni and current trainees.

Our current research focus is on improving care of critically ill patients, seamless transition of care for patients with chronic pulmonary diseases, asthma and lung cancer.
