In the hospital and clinic, I screen my pediatric and adult patients for prior encounters with the police. I ask if they have been stopped, frisked, pulled over or otherwise apprehended. Just as smoking is a risk factor for cardiovascular disease and lung cancer, these encounters confer risk for social isolation, disenfranchisement and worsened health. As doctors, it is our responsibility to provide our patients with anticipatory guidance that will educate them about this process and their rights, for the sake of their health and that of their families. It is also our responsibility to advocate for social policies that give our patients the best chance to live more healthy, productive and dignified lives.
