Background: Stroke recurrence and readmission
• 25% of all strokes are recurrent events1
• 18% of all Medicare readmissions cost $18B2
• After stroke, 25% readmitted within 30 days3
• In GWTG-Stroke, death and readmission after discharge 21% at 30 days4
• The drivers of readmissions are not well understood• Disparities in readmission exist and reasons for these
disparities are not well studied

Background: Readmissions after acute stroke hospitalization in FSR & CMS linked data• All-cause 30-day readmission was 15% (n=16,952)
– 14.4% for Whites (reference*)– 17.2% for Blacks: HR 1.19 (95% CI 0.99-1.44)– 16.7% for Hispanics: HR 1.02 (95% CI 0.87-1.20)– 14.7% for Others: HR 1.03 (95% CI 0.72-1.46)
• Median time d/c to readmission: 11 d • 23.9% readmissions due to stroke
– 16.6% IS or TIA– 1.5% ICH– 5.2% CEA/A&S
• 6.0% NHW, 1.8% NHB, 3.8% H, 7.5% other• 8.2% readmission due pneumonia or UTI

TCSD-S Goals
Goal: Improve stroke outcomes and reduce readmissions
• Identify race-ethnic and sex disparities in hospital-to-home transition of care and outcomes after stroke.
• Identify the key stroke-related and social health-related determinants in hospital-to-home TOSC and stroke outcomes.
– Develop a Transitions of Stroke Care Performance Index
• Develop effective hospital-initiated system level initiatives to reduce disparities

TCSD-S Initiative for TOSC Disparities
• TOSC Index will be developed in first 1,200 participants after which initiatives will be implemented to assess their effect on the TOSC-I and on outcomes.
• Feedback to sites on TOSC metrics, disparities, TOSC-I– Dashboard benchmarked against group
• Educational programs for hospital personnel involved in discharge and TOSC to improve outcomes– Creating multidisciplinary advisory group: patients,
caregivers, therapists, pharmacist, nutritionist, nurses, physicians

data + Sciera zip code-level data
• Review: Data elements, study population, current descriptives, future analytic opportunities

Questions we can ask…• What are the neighborhood barriers to smoking
cessation?– Density of businesses selling tobacco?
• What are the neighborhood barriers to physical activity?– Poverty indices? Walkability score? Prevalence of gyms?
• What are the neighborhood barriers to clinic follow-up?– Poverty indices? Transit score? Clinic count?
• What are the neighborhood barriers to diet modifications?– Density of fast food restaurants? Density of grocery stores?

Conclusions
• We will be able to relate post-stroke care and lifestyle modifications to neighborhood characteristics and resources.
• This information will be used to develop the TOSC PI.
• Will help identify and enhance utilization of valuable community resources and identify patients who may be at risk for low adherence to post-discharge recommended care.

Future Directions
• How do neighborhood characteristics impact long-term outcomes, mortality, hospital readmissions?– Do neighborhood characteristics interact with
other social determinants of health to determine long-term outcomes among stroke survivors?

Planned Enrollment
2400 patients /5 years – 1200 to develop TOSC-PI– 1200 to validate TOSC-PI, evaluate disparities, develop initiatives
to reduce disparities in TOSC
– Total enrolled to date: 145 (overall)– We expected to have 780 enrolled by year 2. We have just
entered year 3.

Best Practices towards Increased Enrollment

Best Practices• Site TCSD-S team will review every day a list of patients expected to be discharged
in the next 48 hours.• Clearly defined Roles and Responsibilities: • The clinical team (including fellows and residents at appropriate sites) will provide
the stroke coordinator a daily discharge list indicating “who is going home” or “potentially going home”.
• Stroke Coordinator communicates everyday with the clinical team (texting, attending rounds) and approaches potential participants on a daily basis.
• Increased Study Notifications for the clinical team including emails and enrollment updates at meetings.
• Increased Communication and Interaction between Study Sites:• Quarterly call with sites to include recruitment by site and review potential
barriers and share best enrolling practices.• Regular emails and use of social media to sites to share any news and enrollment
recognition.
