Introduction:
Stroke patients who receive tracheostomy often undergo prolonged ventilation and have long, complicated ICU stays. Little is known about the hospitalization costs for these patients.
Methods:
We used the National Inpatient Sample from 2008-2017 to identify patients with a primary diagnosis of acute ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage. We identified individuals who received tracheostomy based on procedure codes. We used cost-to-charge ratios to calculate hospitalization costs for each patient and adjusted costs to 2017 US dollars using the Medical Consumer Price Index. We examined differences in hospitalization costs based on age, sex, race, Elixhauser score, length of stay, and early tracheostomy placement (≤7 days). We calculated overall average annual hospitalization costs for all patients with stroke and tracheostomy in the US and compared to the total US acute stroke population inpatient costs.
Results:
We identified an estimated 61,322 acute stroke patients in the US receiving tracheostomy from 2008 to 2017, representing 1.1% of all US acute stroke patients. Stroke patients with tracheostomy had a mean age of 61 years (SD=13.8); 46% were female, 29% black, 12% Hispanic, and 13% rural. Among tracheostomy patients, the mean Elixhauser score was 4.7 (SD=2). The mean hospitalization cost for tracheostomy patients was $117,492 (median $97,063; IQR $64,887-$145,419). Costs were greater for younger patients, females, and those from urban locations. There was no difference in costs for white compared to minority patients. Each additional hospital day accounted for $2,023 in hospitalization costs, and those with early tracheostomy (22% of tracheostomy patients) had lower hospitalization costs (mean $89,811 vs. $125,318; p<0.001). Total US hospitalization costs for acute stroke patients receiving tracheostomy are estimated at $720.4 million per year, which represents 8.1% of total acute stroke hospitalization costs in the US.
Conclusion:
Acute stroke patients who receive tracheostomy account for 1% of all stroke patients, but 8% of all hospitalization costs for stroke in the US.
