Research Overview

Gregory S. Sawicki, MD, MPH, is a pediatric pulmonologist and health services researcher with particular interest in addressing health outcomes, disease self-management, and adherence for children, adolescents, and young adults with chronic respiratory diseases including cystic fibrosis (CF) and asthma.

Dr. Sawicki’s primary research activities are currently focused on the process and outcomes of transition from pediatric to adult focused health care for adolescents with chronic medical conditions. He is conducting a NIH-funded mixed methods qualitative and survey study of adolescents and young adults with CF with the aim of exploring their current experiences with health care transition and disease self-management. In his recent work, he has helped to develop and validate a survey instrument to assess transition readiness for youth with chronic disease, the Transition Readiness Assessment Questionnaire (TRAQ).  This instrument is currently being used in multiple health care transition studies throughout the country. He also is working on the development of quality measures to evaluate the transition to adult care for youth with chronic conditions.

Active Projects

2011-2016 Cystic Fibrosis as a Model for Health Care Transition for Chronically Ill Youth

NHLBI K23 HL105541-01A1
Principal Investigator

The goals of this mentored career development award are to understand the barriers and facilitators of the health care transition process from the perspective of adolescents and young adults with cystic fibrosis. The research will provide important information that can be used in designing health care transition programs for adolescents and young adults with chronic medical conditions.

 

Research Background

Dr. Sawicki received his MD from Harvard Medical School in 2001. He completed residency in Boston Combined Residency Program in Pediatrics in 2004, followed by fellowship in Pediatric Pulmonology at Boston Children’s Hospital (2004-2007). He also completed the Harvard Pediatric Health Services Research Fellowship in 2007, receiving an MPH in Clinical Effectiveness at the Harvard School of Public Health. Dr. Sawicki is currently the Associate Director of the Cystic Fibrosis Center at Boston Children’s Hospital.
