Outcome | Point estimate | 95% CI | P value |
---|---|---|---|
Excess hospital LOS (days) following onset of CBSI* | 7.7 | 0.6-13.5 | 0.015 |
Excess hospital costs ($)† | $13,398 | $1,060-$26,736 | 0.033 |
Based on generalized linear models with gamma distribution
*Generalized linear model, adjusted for all covariates with p < 0.2 in the univariate analysis plus age, APACHE II score, need for mechanical ventilation and need for pressors; manual backwards elimination to arrive at most parsimonious model
†Generalized linear model, adjusted for all covariates with p < 0.2 in the univariate analysis plus age and time from hospital admission to CBSI onset, APACHE II score, need for mechanical ventilation and need for pressors; manual backwards elimination to arrive at most parsimonious model
