Notes:
a
Non-teaching: resident-to-bed ratio = 0; minor teaching: resident-to-bed ratio above 0 but below 0.25; major teaching: resident-to-bed ratio ≥ 0.25
b
Nurse-to-bed ratio calculated as full-time employee nurses divided by total number of hospital beds
c
Nurse skill mix calculated as total number of full-time-employee registered nurses and licensed practical nurses divided by total number of full-time employee nurses
d
Advanced technological capabilities were present if a hospital could perform open heart surgery or organ transplantation, or had a burn unit
