Outcome analyses will be performed only using data related to inpatient / admit day of procedure operations. First, to determine if providers receiving an email about the participants specific bundled compliance affects a patient's overall combined morbidity and mortality a binary logistic regression model will be used. The dependent variable will be combined morbidity and mortality as a Boolean concept. The independent variables entered into the model will be: primary provider AND primary attending both received an email, primary provider did NOT receive an email but the primary attending did receive an email, primary provider did receive an email but the primary attending did NOT receive an email, elixhauser comorbidity score of 2 or more, ASA (binary concept as 1,2 versus 3,4), age (binned by decade of life), male gender, BMI (defined by the World Health Organization Classifications). The investigators can then determine whether providers receiving feedback emails have a risk adjusted improved combined morbidity and mortality rate. If the investigators find this to be true, a mediation analysis at the provider level will be performed to determine if our independent variable (email received) influences the mediator variable (bundle compliance rate) which thereby influences the dependent variable (outcome of interest). The investigators will report the direct effect for receiving the email on the provider's outcome rate as well as the indirect effect of the email that passes through the bundle compliance rate to affect the outcome rate. These values will be reported as the proportion of total effect that is mediated by compliance. Sensitivity analyses for residents/fellow and CRNAs will also be performed. A sub-group analysis excluding the coordinating center is planned.
