Participant Flow

All study outcome data are from patients. We report on the n=664 patients who were attributed to a study clinician with a visit during the intervention period that met denominator criteria for an outcome.

This is a small non-randomized pilot study. This trial enrolled patients with a waiver of informed consent. Clinicians were not enrolled. All outcome data were collected via the electronic health record. This explains why the number of participants started is the same as the number of participants completed.

Baseline Characteristics

We do not have sex data for patients eligible for the diabetes measure so that is why the number analyzed in this section is smaller than number of participants overall.
