A social network of hospital acquired infectionbuilt from electronic medical record data

The Goal: simulate hospital acquired infections (HAI) via social networks using electronic medical records (EMR)

Backround:

HAI EMR Social networks Other models limitations

Mathematical Modeling Random edge assignment

Interview Observation

A social network of hospital acquired infectionbuilt from electronic medical record data

Approach:

Data Extraction

SQL queries Admission-discharge-transfer and clinical documents

Data aggregation

Calculated time for patients sharing rooms, patient contact with health care workers (HCW), or both

Probability framework Simulation

MRSA Influenza

A social network of hospital acquired infectionbuilt from electronic medical record data

Results:

Built a model for

simulating infection Hygiene Isolation Vaccination

A social network of hospital acquired infectionbuilt from electronic medical record data

Significance

Monitor and understand HAIs better

Refine patients and HCW flow

Limitations

Quality of EMR

Contacts outside of EMR

Infection dynamics accuracy

Future

Validate infection dynamics

Validate simulations

Refining
