‡Average marginal effect (***p<0.01, **p<0.05, *p<0.1), with robust SEs corrected for clustering around consultant in parentheses. Probit regressions adjusted for age, gender, ethnicity, deprivation, Charlson Index, number of diagnoses, number of procedures, palliative care, number of emergency admissions in last year, admission method, admission source, transfer-out dummy, admission month and primary diagnosis groups.
