    Perioperative ischemic stroke significantly increases morbidity and mortality in patients undergoing elective surgery. Mechanical thrombectomy can improve ischemic stroke outcomes, but frequency and trend of its utilization for treatment of perioperative ischemic stroke is not studied. We identified adults who underwent elective inpatient surgery from 2008 to 2018 and suffered from a perioperative ischemic stroke from the Premier Healthcare Database. The difference in mechanical thrombectomy usage before and after the updated recommendation inacute stroke guidelines was assessed in a univariate analysis using a chi-squared test. A segmented regression model was created to assess the change in rate over time.Of 6,349,668 patients with elective inpatient surgery, 12,507 (0.2%) had perioperative ischemic stroke. Mean age (and standard deviation) was 69.5 (11.7) years, and 48.8% were female. Mechanical thrombectomy was used in 1.7% patients and its use increased from 0.0% in 3rd quarter, 2008 to 4.4% in 4th quarter, 2018. Significant increase in the use of mechanical thrombectomy was seen after 3rd quarter, 2015 when its use was incorporated in acute stroke treatment guideline (1.14% before 3rd quarter, 2015 versus 3.07% after; p < 0.0001). Amongst patients with perioperative ischemic stroke, patients who received mechanical thrombectomy were more likely to have their surgery performed at a teaching institute (67.3% versus 53.9%). Although a significant increase in rates of utilization of mechanical thrombectomy was observed, rates of utilization remain low, especially in non-teaching hospitals. This highlights improvements in the management of perioperative ischemic strokes and further opportunities to improve outcomes.

    Racial and Ethnic Differences in the Prevalence of Do-Not-Resuscitate Orders among Older Adults with Severe Traumatic Brain Injury.
    (Journal of intensive care medicine, 2022-05-22) Hatfield, Jordan; Fah, Megan; Girden, Alex; Mills, Brianna; Ohnuma, Tetsu; Haines, Krista; Cobert, Julien; Komisarow, Jordan; Williamson, Theresa; Bartz, Raquel; Vavilala, Monica; Raghunathan, Karthik; Tobalske, Anwen; Ward, Joshua; Krishnamoorthy, Vijay

    Background

    Older adults suffering from traumatic brain injury (TBI) are subject to higher injury burden and mortality. Do Not Resuscitate (DNR) orders are used to provide care aligned with patient wishes, but they may not be equitably distributed across racial/ethnic groups. We examined racial/ethnic differences in the prevalence of DNR orders at hospital admission in older patients with severe TBI.

    Methods

    We conducted a retrospective cohort study using the National Trauma Databank (NTDB) between 2007 to 2016. We examined patients ≥ 65 years with severe TBI. For our primary aim, the exposure was race/ethnicity and outcome was the presence of a documented DNR at hospital admission. We conducted an exploratory analysis of hospital outcomes including hospital mortality, discharge to hospice, and healthcare utilization (intracranial pressure monitor placement, hospital LOS, and duration of mechanical ventilation).

    Results

    Compared to White patients, Black patients (OR 0.48, 95% CI 0.35-0.64), Hispanic patients (OR 0.54, 95% CI 0.40-0.70), and Asian patients (OR 0.63, 95% CI 0.44-0.90) had decreased odds of having a DNR order at hospital admission. Patients with DNRs had increased odds of hospital mortality (OR 2.16, 95% CI 1.94-2.42), discharge to hospice (OR 2.08, 95% CI 1.75-2.46), shorter hospital LOS (-2.07 days, 95% CI -3.07 to -1.08) and duration of mechanical ventilation (-1.09 days, 95% CI -1.52 to -0.67). There was no significant difference in the utilization of ICP monitoring (OR 0.94, 95% CI 0.78-1.12).

    Conclusions

    We found significant racial and ethnic differences in the utilization of DNR orders among older patients with severe TBI. Additionally. DNR orders at hospital admission were associated with increased in-hospital mortality, increased hospice utilization, and decreased healthcare utilization. Future studies should examine mechanisms underlying race-based differences in DNR utilization.
