I think creating the infrastructure to have more timely hospital data would be a critical piece to support public health surveillance. The hospital data is very rich, and it's a fabulous resource for both health system managers and researchers to follow patients over a long course of time. The piece that is missing in it is the quick and timely information on admission so that public health has that information as soon as a patient is hospitalized.
It's been challenging with COVID because people very often have very long lengths of stay, and getting the information only when the patient has left the hospital delays things for up to a month.
