1. Examining the Influence of Social,
Socioeconomic (SES), and Medical
Histories on Sepsis-Related Mortality
Sai Dodda, Student Pharmacist Class
of 2021
2. Background and Study Objective
• Sepsis is a leading cause of hospital mortality
– In 2014, 35% of hospitalizations that resulted in death
• Previously identified variables include: race, co-
morbidities, SES (household income), and BMI
• Goal: Understand the relationships between
pre-admission variables (SES, medical, and
social histories) and in-hospital mortality
3. Methods
• Study Design: Retrospective cohort study
• Setting: Barnes Jewish Hospital from 2010-2015.
• Participants: A patients’ first case of sepsis was extracted from the electronic health record
based on ICD-9-CM coding
• Variables:
– Demographics
– Comorbidities
– Social histories (recreational drugs)
– SE variables based on residential zip code - American Community Survey
• Median Household Income
• Percentage of Individuals Below Poverty Level
• Percent High School Graduate or Higher
• Percent Unemployment
– Number of Hospitals Per Zip Code - Center for Medicare & Medicaid Services
– Number of Pharmacies Per Zip Code - Google Maps
4. Analysis
• Evaluate differences between survivors and non-
survivors relative to pre-admission variables
• Analytic methods
– Descriptive Statistics
– Inferential Statistics
• Chi-Square Analysis
• Independent Samples T-test

Number of Pharmacies 5.3 ± 4.0 5.4 ± 4.0 0.1 (-0.11,0.31)
All comparisons per the patient’s residential zip code
9. Discussion/Conclusion
• Contrary results from what is expected in terms of SES, race,
and social history
– African American race patients tend to have less mortality
– Presence of recreational drug use corresponds to less mortality
– Higher household income, lower poverty, and higher education per
zip code correspond to less mortality
• Next Steps
– Evaluation of the contrary results
– Regression Analysis
– Cluster Modeling
– Apply this data to other outcomes (hospital length of stay, type and
number of organ dysfunctions, type of infection)
