| Parameter | Control group (n = 651) | Intervention group (n = 204) | p-value |
|---|---|---|---|
| Mean annual system costs (SD) | €0 | €81 (0) | |
| Mean biosensor costs (SD) | €0 | €63 (0) | |
| Mean ward costs (SD) | €3713 (2654) | €3611 (3200) | 0.003 |
| Mean ICU costs (SD) | €1142 (4977) | €453 (2229) | 0.005 |
| Mean total costs (SD) | €4855 (5827) | €4064 (4231) | <0.001 |
p-values reflect the difference between control and intervention period based on a Mann–Whitney test. Annual system costs were determined based on annual license costs, labor costs and costs per biosensor and divided by the total number of patients in the intervention group. Ward costs and ICU costs were based on the costs stated in the costing tool developed by the institute for Medical Technology Assessment (iMTA) [25] and adjusted for inflation using the average consumer price index in the period of 2017–2021 as indicated by Statistics Netherlands and multiplied by the number of days on the ward or ICU per patient.
ICU: Intensive care unit; SD: Standard deviation.
