  • Note: COPD = chronic obstructive pulmonary disease, LACE = length of stay, acuity of admission, comorbidities and emegency department visits, SD = standard deviation.

  • * Calculated using analysis of variance (continuous variables) or χ2 test (binary and categorical variables).

  • p value comparing overall proportion of discharges (binary) that were a “Top 5 diagnoses” across physician experience groups.

  • Resource intensity weight values provide a measure of a patient’s relative resource consumption compared with an average typical inpatient cost and are generated by the Canadian Institute of Health Information for each case mix group.

  • § Overall p value for discharge disposition (categorical) across physician experience groups.
