Objective To determine the cost-effectiveness of selective digestive decontamination (SDD) as compared to selective oropharyngeal decontamination (SOD) in intensive care units (ICUs) with low levels of antimicrobial resistance.

Design Post-hoc analysis of a previously performed individual patient data meta-analysis of two cluster-randomised cross-over trials.

Setting 24 ICUs in the Netherlands.

Participants 12952 ICU patients who were treated with >= 1dose of SDD (n=6720) or SOD (n=6232).

Interventions SDD versus SOD.

Primary and secondary outcome measures The incremental cost-effectiveness ratio (ICER; ie, costs to prevent one in-hospital death) was calculated by comparing differences in direct healthcare costs and in-hospital mortality of patients treated with SDD versus SOD. A willingness-to-pay curve was plotted to reflect the probability of cost-effectiveness of SDD for a range of different values of maximum costs per prevented in-hospital death.

Results The ICER resulting from the fixed-effect meta-analysis, adjusted for clustering and differences in baseline characteristics, showed that SDD significantly reduced in-hospital mortality (adjusted absolute risk reduction 0.0195, 95%CI 0.0050 to 0.0338) with no difference in costs (adjusted cost difference (sic)62 in favour of SDD, 95%CI -(sic)1079 to Euro935). Thus, SDD yielded significantly lower in-hospital mortality and comparable costs as compared with SOD. At a willingness-to-pay value of (sic)33633 per one prevented in-hospital death, SDD had a probability of 90.0% to be cost-effective as compared with SOD.

Conclusion In Dutch ICUs, SDD has a very high probability of cost-effectiveness as compared to SOD. These data support the implementation of SDD in settings with low levels of antimicrobial resistance.
