Abstract TP167: Burden And Impact Of Comorbid Depression On In-hospital Outcomes Of Acute Ischemic Stroke-related Admissions In Women Of Reproductive Age Group: A Propensity-matched Analysis

Abstract

Background: Depression has been identified as a risk factor for acute cerebrovascular events. Due to limited data focused on young females, we studied the burden and impact of comorbid depression on outcomes of acute ischemic stroke (AIS)-related admissions in young women of the reproductive age group. Methods: We used the National Inpatient Sample (2018) to identify admissions of young females (age 18-44 years) with AIS; and further classified it into two demographically (age, race, payer status, income) matched (1:1) groups based on the presence of comorbid depression. Comorbidities and outcomes were compared using relevant ICD-10 codes. Multivariable regression was used to analyze the association of comorbid depression with in-hospital mortality. Results: In 15850 young females admitted with AIS in 2018, 2465 (15.6%) had comorbid depression. Post-matching, the study cohort consisted of 4610 women admitted with AIS (Median age: 37, 66.2% whites) and 2305 women in each cohort, with and without depression. The matched AIS-depression arm often had younger women (median 37 vs 39 years), patients from the lower-income quartile (47.3% vs. 34.5%), and higher rates of obesity, peripheral vascular disease, and prior history of stroke but a lower prevalence of CVD risk factors [Table 1]. The depression arm had a non-significant odd of all-cause mortality (OR 1.32, 95%CI:0.64-2.74) when adjusted for sociodemographic confounders and comorbid risk factors (p=0.452). The LOS was shorter (median 4 vs 5 days) with comparable hospital charges in the depression arm vs. no depression arm (p<0.001). Conclusion: This study revealed a nearly 15% burden of depression in young females admitted for AIS without significant impact on all-cause mortality when controlled for confounders. The impact of depression on long-term AIS outcomes needs further evaluation.
