Figure 2. Intervention Effect on Palliative Care Consultation in Non-Cancer Patients (DID) (N=13356 Non-Cancer Hospitalizations).

Figure 2.

DID = Difference in Differences

The predicted percentages illustrating the DID for a non-cancer patient are based on fully-interacted model of intervention versus control, post- versus pre-intervention time, and cancer versus non-cancer patient. The model also includes a random-effect for physician and multiple control variables, which are held constant at their mean or modal values: a 60-year old male, with 50 total relative value units (RVUs) charged over the hospitalization, Charlson comorbidity score of 3 points, length of stay of 6 days, and no 30-day recent hospitalization.
