Clinical decision support on eICU dataset

Data access

• We are using the eICU database v2.0. This database requires credential access. Sign up here

Some important data Links:

• Instructions to get eICU postgres locally
• Official paper explaining dataset
• Database schema
• Table information

Data extraction

• Features for mortality prediction and length of stay prediction are replicated according to this work
• Different from the authors, we are operating on eICU database v2.0

Extraction

• Run extract-features.ipynb with eICU credentials to download rawdata.csv file
• Summary of features and tables where the feature was extracted from are as follows:

Feature	Table location	Data type
Heart rate	apacheapsvar	Numerical
Mean arterial pressure	formula	Numerical
Diastolic blood pressure	vitalperiodic	Numerical
Systolic blood pressure	vitalperiodic	Numerical
O2	lab	Numerical
Respiratory rate	apacheapsvar	Numerical
Temperature	apacheapsvar	Numerical
Glucose	apacheapsvar	Numerical
FiO2	apacheapsvar	Numerical
pH	apacheapsvar	Numerical
Height	patient	Numerical
Weight	patient	Numerical
Age	patient	Numerical
Admission diagnosis	patient	Categorical
Ethnicity	patient	Categorical
Gender	patient	Categorical
Glasgow Coma Score Total	formula	Numerical
Glasgow Coma Score Eyes	apacheapsvar	Numerical
Glasgow Coma Score Motor	apacheapsvar	Numerical
Glasgow Coma Score Verbal	apacheapsvar	Numerical

Formula used in the table

               mean arterial pressure = SBP + 2(DBP) /3
               GCS total = GCS sum of eyes, motor, verbal
