Abstract

BACKGROUND: Patients with stroke receiving invasive mechanical ventilation (IMV) and tracheostomy incur intense treatment and long hospitalizations. We aimed to evaluate US hospitalization costs for patients with stroke requiring IMV, tracheostomy, or no ventilation. METHODS: We performed a retrospective observational study of US hospitalizations for acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage receiving IMV, tracheostomy, or none using the National Inpatient Sample, 2008 to 2017. We calculated hospitalization costs using cost-to-charge ratios adjusted to 2017 US dollars for inpatients with stroke by ventilation status (no IMV, IMV alone, tracheostomy). RESULTS: Of an estimated 5.2 million (95% CI, 5.1–5.3) acute stroke hospitalizations, 2008 to 2017; 9.4% received IMV alone and 1.4% received tracheostomy. Length of stay for patients without IMV was shorter (median, 4 days; interquartile range [IQR], 2–6) compared with IMV alone (median, 6 days; [IQR, 2–13]), and tracheostomy (median, 25 days; [IQR, 18–36]; P <0.001). Mortality for patients without IMV was 3.2% compared with 51.2% for IMV alone and 9.8% for tracheostomy ( P <0.001). Median hospitalization costs for patients without IMV was $9503 (IQR, $6544–$14 963), compared with $23 774 (IQR, $10 900–$47 735) for IMV alone and $95 380 (IQR, $63 921–$144 019) for tracheostomy. Tracheostomy placement in ≤7 days had lower costs compared with placement in >7 days (median, $71 470 [IQR, $47 863–$108 250] versus $102 979 [IQR, $69 563–$152 543]; P <0.001). Each day awaiting tracheostomy was associated with a 2.9% cost increase (95% CI, 2.6%–3.1%). US hospitalization costs for patients with acute stroke were $8.7 billion/y (95% CI, $8.5–$8.9 billion). For IMV alone, costs were $1.8 billion/y (95% CI, $1.7–$1.9 billion) and for tracheostomy $824 million/y (95% CI, $789.7–$858.3 million). CONCLUSIONS: Patients with acute stroke who undergo tracheostomy account for 1.4% of stroke admissions and 9.5% of US stroke hospitalization costs. Future research should focus on the added value to society and patients of IMV and tracheostomy, in particular after 7 days for the latter procedure given the increased costs incurred and poor outcomes in stroke.
