The Division of Pulmonary, Critical Care, and Sleep Medicine offers comprehensive and individualized care for adult patients suffering from common and uncommon respiratory disorders and sleep disorders. The North Shore-LIJ Health System provides expert treatment and management for all of them, from asthma and allergies to emphysema and cystic fibrosis. Our comprehensive Sleep Disorders Center provides diagnostic and treatment services for sleep apnea, insomnia, and other conditions.
Physicians provide an array of services at the Adult Cystic Fibrosis Center, Beth Thalheim Asthma Center (ALA Network), Rehabilitation Center, Advanced Lung Disease and Pulmonary Hypertension Center, Sleep Disorders Center, and the outpatient pulmonary practice. Our faculty are leaders in applications for critical care ultrasonography and in demonstrating that people other than radiologists and cardiologists can be proficient. The division has spearheaded the development of national ultrasonography courses and organized training for most of New York City’s first-year pulmonary and critical care fellows – helping raise the level of proficiency in ICUs across the city. At North Shore-LIJ, critical care ultrasonography includes transesophageal echocardiography and training for house staff as well as fellows.

Negin Hajizadeh, MD
Dr. Hajizadeh is Assistant Professor of Medicine at Hofstra Northwell School of Medicine and joined Northwell in 2014. She works clinically as a medical intensivist at LIJ Medical Center and North Shore University Hospital. Her research interest is in comparative effectiveness research and decision-making science with a focus on translating this science into instruments that can be used by patients and their clinicians for an informed end of life decision making – specifically critical care decision making in patients with advanced chronic diseases. Her goal is to inform end-of-life care planning with personalized, prognostic data, and with tools to effectively and compassionately communicate this data to patients.
Thus far, she has developed a mathematical model which estimates outcomes for patients with severe COPD who choose to receive mechanical ventilation versus not, in the event of critical illness. She has incorporated this model into a decision aid (InformedTogether) for use at the point of outpatient clinical care, with the ability for patients to then continue viewing the decision aid at home with their family members. This work is funded by the NIH-NIA (National Institute of Aging) to be refined using patient and clinician feedback, and to be tested in a pilot clinical study for point of care shared decision-making about advance care plans. She also is the co-PI on a grant from the Cystic Fibrosis Foundation to develop a mathematical model that estimates survival for patients with Cystic Fibrosis and to communicate this within a similar decision aid.
