Regression coefficients, odds ratios and risk scores for predictors of adverse psychological outcome

Predictors	Regression coefficient	Odds ratio	95% CI	Risk score = Regression coefficient × 25
Pre-existing diseases (CCI >3)	2.02	7.52	2.01 to 28.1	50.5
Parent to children <18 years	1.26	3.51	1.39 to 8.89	31.5
Previous psychological problems	1.14	3.13	1.12 to 8.76	28.5
In-ICU agitation	0.8	2.23	-0.80 to 6.22	20
Unemployed/sick-leave at ICU admission	0.48	1.62	-0.54 to 4.88	12
Appeared depressed in ICU	0.30	1.35	-0.55 to 3.31	7.5

In order to make risk scores in the predictive screening instrument easier to compute the coefficients have been multiplied by 25 and named "risk score". CCI, Charlson Co-morbidity Index; CI, Confidence interval; ICU, Intensive care unit
