Cost-effectiveness-analysis of ultrasound guidance for central venous catheterization compared with landmark method: a decision-analytic model

Table 4 Results of the structural sensitivity analyses

Strategy	Costs (€)	Incremental costs (€)	Complications per person	Incremental effect (averted complications per person)	ICER (€ per averted complication)
Alternative 1: Doubled complication rates, adults and real time-cannulation
Ultrasound guidance	141	− 277	0.076	0.267	Dominates^a
Landmark method	418		0.343
Alternative 2: Tripled complication rates, adults and real time-cannulation
Ultrasound guidance	203	− 449	0.123	0.457	Dominates^a
Landmark method	652		0.579
Alternative 3: Paediatric and adult patients, real-time cannulation
Ultrasound guidance	70	− 161	0.050	0.127	Dominates^a

ICER incremental cost-effectiveness ratio
^aUltrasound guidance is less costly and more effective in averting complications compared with landmark method
