INS and diabetes mellitus: Adjusted multiple regression found mean daily insulin prescription was predicted to be 40.1 units greater in people with diabetes than those without, 95% CI, [29.013–51.163], p ≤ 0.001, and for each increase in APACHE-II score, insulin prescription was predicted to increase by 1.4 units per day, 95% CI [0.514–2.234], p = 0.003.
