This cluster-randomized trial will assess the effectiveness of a precision feedback service on anesthesia provider performance. The precision feedback service enhances a standard audit and feedback (A&F) email with a brief message and visual display about high-value performance information. The control arm will receive a standard "one size fits most" A&F email that is currently sent to anesthesia providers each month. Hypothesis: Providers receiving precision feedback will increase a) care quality for improvable measures and b) email engagement (click-through and dashboard login rates) when compared with providers receiving standard A&F emails. The study investigators will assess unintended consequences in a mixed-methods process evaluation.

Inclusion Criteria (assessed before interventional period):

• Participation in the Multicenter Perioperative Outcomes Group (MPOG) provider feedback email program.

Exclusion Criteria (assessed after interventional period):

• Ended participation in the MPOG provider feedback email program for any reason during the study period
• Changed professional roles (e.g. transitioned from resident to attending) before the end of the intervention period
• Changed institutions during the study period
• Had no institution-selected quality measures in common between the pre-intervention and intervention period
• Were not candidates to receive a precision feedback email for the majority of the trial.
