Comparison of the weekly number of 9‐1‐1–initiated EMS activations with patient contact from 2017 to 2020. The number of states submitting to the national EMS repository increased over the study period (2017, 32 states; 2018, 40 states; 2019, 44 states). The District of Columbia submitted PCRs in each time period. States enrolling in the National EMS repository commonly begin submitting PCRs at the beginning of the calendar year. No state stopped submitting PCRs once enrolled. PCR = patient care record.
