Probabilistic analysis results of the NPP cost-effectiveness

NPP	Combined			SCU/HDU			NICU
NPP	Point estimate	Lower 95% limit	Upper 95% limit	Point estimate	Lower 95% limit	Upper 95% limit	Point estimate	Lower 95% limit	Upper 95% limit
Incremental implementation costs, £	294	32	808	553	134	1277	98	57	149
Incremental lifetime costs, £	−943	−1486	−469	−909	−1514	−362	−867	−1443	−357
Incremental total costs, £	−649	−1284	35	−356	−1131	539	−769	−1344	258
Incremental QALYs	0.01	0.01	0.02	0.01	0.01	0.02	0.01	0.01	0.02
Net monetary benefit*, £	886	130	1621	586	−372	1475	987	355	1675

*We used a willingness-to-pay threshold of £20 000 per QALY gained.
HDU, high dependency unit; NICU, neonatal intensive care unit; NPP, National PReCePT Programme; PReCePT, Preventing Cerebral Palsy in Pre Term labour; QALYs, quality-adjusted life-years; SCU, special care unit.
