About the Investigator

Negin Hajizadeh, MD, MPH is a pulmonary and critical care physician whose research focuses on using decision-analytic modeling to better inform and encourage shared decision making about treatments when patients become critically ill. Dr. Hajizadeh’s work focuses on informing health care policy in the Intensive Care Unit (ICU) to ensure that patients receive care that produces outcomes in line with their preferences and expectations. She is particularly interested in informing patients with advanced chronic illness because these patients often have predictable events that lead to the last stage in their life, and can be better prepared to make these decisions. By providing tools to the patients, their families and their doctors she hopes to support meaningful advance care planning.

After completing her undergraduate education at Smith College – where she majored in both Women’s Studies and Biology, Dr. Hajizadeh went on to earn her M.D. from Brown University Medical School through the Dartmouth-Brown Combined Medical Program. Upon finishing her degrees, Dr. Hajizadeh completed her internship and residency at Tufts University New England Medical Center in Boston, MA. She then completed a Pulmonary and Critical Care Fellowship at Yale University School of Medicine in New Haven, CT. Dr. Hajizadeh also received a Masters in Public Health at the Yale School of Public Health and completed a National Library of Medicine Medical Informatics Fellowship at the Yale School of Medicine. These experiences were integral to her decision to focus her career on informing doctor-patient decision making by integrating decision tools within the electronic health record. After completing her fellowships, Dr. Hajizadeh became a full-time Instructor at New York University School of Medicine in the Department of Medicine, a part-time Instructor for the Yale University School of Medicine in the Section of Pulmonary and Critical Care, and a Lecturer at the Yale Center for Medical Informatics.

In 2010, Dr. Hajizadeh was awarded a K12 Grant by the Agency for Healthcare Research and Quality (AHRQ). In 2011, she was further honored with the Society for Medical Decision Making (SMDM) designation to her AHRQ Mentored Clinical Scientists Comparative Effectiveness Development Award.
In 2014, Dr. Hajizadeh was awarded an R21 grant from the National Institute on Aging. The major goals of this grant are to revise a brief decision aid which supports shared decision making between doctors and severe COPD patients about treatments for acute respiratory failure, and to test the decision aid for quality and feasibility of implementation. In 2015, Dr. Hajizadeh was awarded a research grant through the Cystic Fibrosis Foundation. This study seeks to develop and test a decision aid for advance care planning for CF patients and their physicians to use at the point of outpatient care. In addition, along with Dr. Anna Mathew and Dr. Marty Lesser and Meredith Akerman, models of survival for patients with advanced stage CF are being developed. In 2016, Dr. Hajizadeh was awarded a PCORI (Patient-Centered Outcomes Research Institute) grant supporting her research to explore telehealth-delivered pulmonary rehabilitation as an effective alternative for Hispanic patients with COPD. The goals of this project are to determine whether telehealth delivered pulmonary rehabilitation leads to better outcomes when compared to standard pulmonary rehabilitation. Latino patients face significant access barriers, including: difficulty with transportation, low program usability/acceptability and insurance coverage, resulting in low referral to pulmonary rehabilitation. The comprehensive disease management program will address these barriers by providing pulmonary rehabilitation at home or in community settings via telehealth.

Dr. Hajizadeh served as junior faculty at NYU School of Medicine in the Department of Population Health from 2010-2013, and continues as Adjunct Assistant Professor. In 2014, Dr. Hajizadeh joined Northwell Health and Hofstra Northwell School of Medicine as Assistant Professor of Medicine where she continues to actively pursue her research, and to provide care for patients as an Intensive Care Attending physician at LIJ. In May 2016, she was promoted to the rank of Associate Professor of Medicine. Dr. Hajizadeh is an active member of The Society for Medical Decision Making and the American Thoracic Society and also serves on the editorial board for the Journal of Medical Decision Making.

Research Focus

Dr. Hajizadeh’s research focuses on improving end of life care in patients with advanced chronic disease, by informing decision making with prognostic data and effective doctor-patient communication in advance of critical illness. Her broad research skills include comparative effectiveness methods, the science of decision making, shared decision making and patient-centered effective communication/translation of evidence. She has received in-depth medical informatics and comparative effectiveness research training and has completed an AHRQ funded K12 Comparative Effectiveness Research career development award (PI, Braithwaite, NYU). Dr. Hajizadeh’s expertise is in mathematical modeling (Markov modeling) of alternative treatment decisions for patients with advanced chronic diseases, specifically  considering patients’ perspectives. Her work focuses on ‘translating’/communicating mathematical modeling results to patients and their clinicians, within brief decision aids feasible to use at the point of clinical care.  Thus-far she has developed and validated a mathematical model for patients with severe COPD choosing between alternative advance directives. She has incorporated this mathematical model within a brief, electronic, web-based decision aid that is currently being tested for usability at an outpatient clinic. Dr. Hajizadeh has experience building a mathematical model for a complex and highly emotionally charged decision for patients with a specific chronic disease. She was awarded a R21 from the NIA in 2014 to refine this decision aid and to test the feasibility of its implementation in the outpatient pulmonary clinics at NSLIJ and at Queens Hospital. In 2015, her team was granted an award from the Cystic Fibrosis Foundation to develop prognostic models for survival in patients with Cystic Fibrosis and to then translate this data into a decision aid for use at the point of care.

In 2009, while completing her medical informatics fellowship at Yale School of Medicine, Dr. Hajizadeh was also an Instructor of Medicine in the Department of Medicine. She then moved to a part-time position at Yale as instructor, and full –time at NYU School of Medicine. From 2010 to 2013 she was an Instructor of Medicine at NYU School of Medicine, as well as a K12 Comparative Effectiveness Research Scholar. In 2013 she was granted promotion to Assistant Professor, tenure track at NYU School of Medicine. During the three years as Instructor of Medicine Dr. Hajizadeh published 6 manuscripts in peer reviewed medical journals. During the past three years she has submitted one R01 Grant application to the NINR, three PCORI (Patient Centered Outcomes Research Institute) applications (one of which is currently under review), one R21 application to the NIAAA, one R21 to the NIA, and a K23 application to NHLBI. She also taught classes in the decision analysis class for post-doctoral students in the CER training program at NYU School of Medicine. Dr. Hajizadeh also teaches a class on Bias in Decision Making at the annual Society for Medical Decision Making meetings. She is core faculty for both of these classes and will continue to teach over the next several years. She has also presented my work at national academic meetings including two podium presentations (SMDM and NLM). Dr. Hajizadeh has dedicated approximately 70% of my time to research, 5% to teaching and the remaining 25% to clinical work. Future plans include establishing a center for collaborative preparation for end of life decision making in patients with advanced chronic diseases which will expand upon my current work for patients with severe COPD and Cystic Fibrosis.
