SE: standard error; CVD: cerebrovascular disease; PVD: peripheral vascular disease; CPD: chronic pulmonary disease; Emergency: patient first admitted via emergency department. Another health facility: patient transferred from nursing home or other ancillary nonacute care health facility. Routine: scheduled nonmergent admission, typically directly from home, or outpatient program. Cancer: total number of patients with cancer (including metastatic cancers).
