Toughened immigration policies exacerbate barriers to public benefits and health care for immigrants. The objective of this study is to examine the impact of the immigration climate on the utilization of pediatric emergency and ambulatory care services and elucidate ways to best support Latino immigrant families. This is a cross-sectional study involving surveys and interviews with Latino parents (≥ 18 years) in the pediatric emergency department. Forty-five parents completed surveys and 40 were interviewed. We identified two themes on health care utilization: fear of detention and deportation in health care settings, and barriers to pediatric primary care; and two themes on how pediatric providers can best support Latinos: information and guidance on immigration policies, and reassurance and safety during visits. Despite immigration fears, Latino parents continue to seek health care for their children. This highlights the unique access that pediatric providers have to this vulnerable population to address immigration fears and establish trust in the health care system. Health care providers are also perceived as trusted figures from whom Latino families want more information on the latest immigration policies, immigration resources, and education on legal rights during medical visits.
