  • Patient Experience of Care Survey
    This survey is an important reporting tool and serves as the source for the Healthy People 2020 measure DH-5 – Transition Planning. The NHPCC reports data to HRSA as part of its federal funding grant. Reporting data for 2020 has been challenging given the COVID-19 pandemic and we appreciate all the effort HTCs have made to collect 849 valid survey results for 2020 despite limited in-person clinic visits.
