DRG affected admissions of patient with a low burden of disease. Patients were stratified by the year of admission, the origin of admission (in-house (a, b); from external hospitals (c, d)) and clinical severity at admission (SAPS II score < 40 (a, c); SAPS ≥40 (b, d)). Observed admissions in 2013 (x) are considered significantly affected by DRG if outside the 95% CI (whisker) of predicted admissions for 2013 (-) based admissions observed 2009 to 2012 (•). Forecasted and observed admissions were 1919 (95% CI: 1898–1940) and 1972 in (a), 703 (95% CI: 658–748) and 709 in (b), 518 (95% CI: 482–554) and 436 in (c) and 332 (95% CI: 269–395) and 302 respectively in (d)
