Description

Problem:

• Missing data is common in clinical variables in MIMIC-III.
• It can be very time consuming for data scientists to consult clinicians about imputation strategies for individual variables.

Solution:

• We have prepared a spreadsheet containing common variable and general guidelines for imputation for both static measurements and time series measurements based on our clinical opinion.
• Suggestions for Clinical Variables.xlsx

Feedback Wanted:
