MIMIC-IV-eventlog-merger

A script designed to merge the admissions and transfers eventlogs of the MIMIC-IV dataset.

Setup

The following changes have to be performed manually to the datasets:

Transfers Eventlog:

• switch column names of concept:name and eventtype

Admissions Eventlog:

• rename disch to discharge
• append one of the eventlogs onto the other

Changes

Your eventlog's subject_id will be enriched in the following way:

• admissions contain eventtype (if available) or admission_location (if available)
• transfers contain eventtype (if available)
• edreg/edout is deleted as the information is stored in the ED event
• duplicate events will be removed within the specified timeframe

Input

The script takes three inputs, namely:

• input_file, your merged eventlogs
• time_frame, the time frame in which you want duplicates removed
• output_file, your output file, defaults to merged_output_file.csv

Example:

node eventlog-merger.js --input_file "./admission_merged.csv" --time_frame 3600000 --output_file "./merged_output_file.csv"
