Cost effectiveness of outpatient lumbar discectomy

Table 5 Cost-utility analysis for observed admission time and 1-day admission time

	3-month		6-month
	AUC	CfB	AUC	CfB
Observed admission time
ICER (outpatient vs inpatient)	€345,755.1/QALY	€135,753.2/QALY	–	–
%Simulations outpatient better than inpatient	65.2%	73.0%	68.9%	71.8%
1-day admission time
ICER (outpatient vs inpatient)	€207,541.7/QALY	€80,338.7/QALY	–	–
% simulations outpatient better than inpatient	58.4%	54.4%	66.3%	66.4%

ICER values for 6-month assessment are not presented because, since outpatient is associated both with lower costs and higher utility gains, inpatient was dominated. AUC, Area under the curve; CfB, Change from Baseline; ICER, Incremental Cost-Effectiveness Ratio; QALY, Quality-adjusted life year
