Description of Variables for Estimating Hospital Costs for Mechanical Thrombectomy Interventions
| Variables | Value (2022 CAD) | Description | Reference |
|---|---|---|---|
| C_CDT_I743 | $15,582 | Hospital costs of the CDT treatment for patients with arterial acute limb ischemia. We assumed it was same as the costs of the treatments of CCI code of 1.KG.35.HH-1C. | OCCI,141 Table 44 |
| C_CDT_I802 | $16,736 | Hospital costs of the CDT treatment for patients with acute DVT. We assumed it was same as the costs of the treatments of CCI code of 1.KX.35.HH-1C. | OCCI,141 Table 44 |
| C_PMT_ALI | $1,670 | The list price of AngioJet disposables (the Solent family [$1,500] and PowerPulse kit [$170]) for treating blocked arteries. We assumed that it is used for patients with arterial acute limb ischemia. | Shelley McFeetors, Boston Scientific |
| C_PMT_DVT | $3,070 | The list price of AngioJet disposables for PMT per procedure for DVT population. Zelante DVT ($2,900), and PowerPulse kit ($170). We assumed that it was used for patients with deep vein thrombosis. | Shelley McFeetors, Boston Scientific |
| C_MT_ Indigo | $5,725 | The approximate costs of disposable material using Indigo System is about $4,523 USD ($5,725 CAD) per vacuum aspiration procedure. There was no breakdown cost information. | Brian Sneek, Penumbra |
| C_CDT_device | $500 | Cost of CDT supplies for arterial or vein diseases. Note: this cost is included in hospital costs of CDT treatment (C_CDT_I743 or C_CDT_I802). For those who received the PMT or vacuum aspiration alone (without CDT), the cost of CDT supplies needs to be subtracted from CDT treatment costs. | Dheeraj Rajan, email communication, April, 2022 |
| Pct_PMTA_ALI | 52% | The proportion of PMT (AngioJet) procedures completed without concurrent CDT (i.e., PMT alone) for patients with arterial acute limb ischemia. | PEARL registry122 |
| Pct_MTA_ALI | 53% | The proportion of vacuum aspiration (Indigo) procedures completed without concurrent CDT (i.e., MT alone) patients with arterial acute limb ischemia. | Lopez et al, 2020139 |
| Pct_PMTA_DVT | 39% | The proportion of PMT (AngioJet) procedures completed without the concurrent CDT (i.e., PMT alone) for patients with acute DVT. | PEARL registry85 |
| Pct_MTA_DVT | 20% | The proportion of the vacuum aspiration (Indigo) procedures completed without the concurrent CDT (i.e., MT alone) patients with DVT. | Assumed |
| SD_ICU_ALI | 0.57 d (13.64 h) | Saving of ICU time (assuming ICU time is the duration of thrombolytic therapy), MT with or without CDT versus CDT alone for adults with arterial acute limb ischemia. | Meta-analysis (see clinical review, above) |
| SD_ICU_DVT | 1.18 d (28.35 h) | Saving of ICU time (assuming ICU time is the duration of thrombolytic therapy), MT with or without CDT versus CDT alone for adults with deep vein thrombosis. | Meta-analysis (see clinical review, above) |
| UC_ICU | $4,005 | Cost per day in ICU. Includes nursing, operating room, laboratory, medical imaging, pharmacy, etc.), but does not include physician fees. | Evans et al, 2018145 |
| SD_ward_ALI | 0.53 d | Saving of ward time, MT with or without CDT versus CDT alone (1.10-.57 d; savings in total hospital stay minus the savings in ICU time) for adults with arterial acute limb ischemia. | Meta-analysis (see clinical review, above) |
| SD_ward_DVT | 1.42 d | Saving of ward time, MT with or without CDT versus CDT alone (2.60-1.18 d, excluding the savings in ICU time) for adults with DVT. | Meta-analysis (see clinical review, above) |
| UC_ward | $1,224 | Cost per day in ward. Includes nursing, laboratory, medical imaging, pharmacy, etc.), but does not include physician fees. | Evans et al, 2018145 |
