Abbreviations: CI, confidence interval; EHR, electronic health record; PTSD, posttraumatic stress disorder.
Note: Burnout was analyzed using linear least-squares regression and PTSD and depression-related outcomes were analyzed using negative binomial regression. Unadjusted means correspond to means unadjusted for covariates. Adjusted means correspond to means from multivariable models adjusted for variables with p < 0.10 in the univariable analyses (see Appendix A and B ). Bold indicates p value <.10.
