Clinical Training

Core Clinical Rotations

Pulmonary Consult Service 

On the Pulmonary Consult Service, fellows will perform pulmonary consultations on patients with a variety of pulmonary diseases, including pleural diseases, lung cancer, inpatient manifestations of obstructive lung disease and ILD, and respiratory failure. Each fellow will become proficient in pleural procedures on this rotation. 

Medical Intensive Care Unit 

The Erlanger Baroness MICU is a 24 bed state-of-the-art, recently renovated unit. It is one of the highest acuity ICUs in the region. Fellows will be responsible for leading academic rounds in the ICU, supervision of residents and medical students, and performing basic critical care procedures (endotracheal intubation, bedside bronchoscopy, critical care ultrasound, central line placement). Fellows will learn pathophysiology , diagnosis, and therapy of high acuity critical care disease processes in a multi-disciplinary approach that includes residents, pharmacists, nursing, case management, palliative care, PT/OT, and respiratory therapy. Fellows will also learn the fundamental skill of ICU triage. 

Pulmonary Procedures Rotation

Fellows on this rotation will be responsible for performing, under the supervision of a pulmonary attending, basic bronchoscopy procedures in the bronchoscopy lab. Fellows will become proficient in recognizing basic pulmonary anatomy,  bronchoalveolar lavage, endobronchial ultrasound, and trans-bronchial biopsies. They will gain exposure to endobronchial valve placement, robotic navigation bronchoscopy, balloon dilatation, APC, cryotherapy, and stent placement. This rotation will also include understanding and interpreting pulmonary function testing. 

Neuro Critical Care and Cardiac Critical Care

Fellows will be responsible for consultative and primary service care for neuro critical care and cardiac critical care patients through a close collaboration with the division’s critical care faculty and the neurology, neurosurgery, cardiology, and cardiothoracic groups. 

Pulmonary Outpatient Continuity Clinic

Fellows will have a robust continuity clinic experience in the Pulmonary Clinic at Erlanger Medical Mall. Fellows will have their own patient panel and will see new and established patients. They will be exposed to a comprehensive patient population which includes dyspnea and chronic cough evaluation, COPD, asthma, sarcoidosis, ILD, pulmonary hypertension, lung nodules, lung cancer, and sleep apnea. 


Block Schedule

First year fellows will begin our program with a boot camp consisting of basic introduction to Pulmonary and Critical Care Medicine, including basic didactics to introduce the specialty, simulation, and procedure training. The block schedule for core rotation content is listed below and is not inclusive of ambulatory and elective time.

Core Rotation Content Areas Duration
Pulmonary Consults 6 months
Pulmonary Procedures 4 - 5 months
Medical Intensive Care Unite 6 months
Night Intensive Care 3 months
Critical Care – Cardiac, Neurology, Surgical, Consults 3 - 4 months
Research 6 months



Fellow’s Case Conference

Fellows will be responsible for presenting cases at this conference which demonstrate clinical and radiographic pulmonary and critical care principles. This a case- based, interactive conference is created to develop clinical reasoning skills within the scope of the specialty.

Didactic Conference

Fellows will receive up to date education from our faculty on Critical Care and Pulmonary topics essential for a successful practice in the field of Pulmonary and Critical Care, as well as success in board certification.

Thoracic Tumor Board

The Pulmonary and Critical Care Division participates in Thoracic Tumor Board every other week,  a multi-disciplinary conference comprising of thoracic surgery, radiology, pathology, radiation oncology, oncology, pulmonology, and oncology navigators. Lung cancer cases are discussed in multi-disciplinary fashion to answer questions regarding diagnosis and management.

Pulmonary Radiology Conference

The Pulmonary and Critical Care Division also participates in Pulmonary radiology conference, a multi-disciplinary conference designed to discuss malignant and non-malignant pulmonary cases that require multi-disciplinary discussion with in-depth radiology review.

Internal Medicine Grand Rounds 

Fellows will attend Internal Medicine Grand Rounds once a month, hosted by the Chair of Medicine. Topics include cutting edge Internal Medicine topics intended for continuing education for the entire Department of Medicine.

Physiology Conference

Pulmonary physiology conference will be held every other week and will consist of a discussion on complex physiology concepts through journal articles and interpretation of cardiopulmonary exercise testing. Articles are reviewed and discussed alongside pulmonary physiologists at Brown Medicine lead by Dr. Eric Gartman at the University of Limerick in Ireland though the help of video conferencing.

Clinical Care

The Pulmonary and Critical Care Division provides advanced care for patients with illnesses and diseases related to the lungs, breathing, and sleep. Our mission is to help all our patients live fuller, more active lives through education and excellent care, with a strong focus on quality, compassion, and state-of-the-art services. Our team of board-certified physicians offers highly specialized expertise to help prevent and reduce the incidence of pulmonary diseases and chronic conditions. Our Fellows will be an integral part of the Pulmonary and Critical Care health care team.
