healmatcher 0.0.21

Fast and simple probabilistic data matching package

healmatcher

• healmatcher is a simple but fast probabilistic data matching package developed by NYULH HEAL Lab.
• The package is best optimized for matching healthcare database (e.g. EHR) as it has designed to link Medicaid and Client Database System data.
• Splink package is extensively being used to run core linkage processes.
• Currently, the model supports 4 variables (sex, date of birth, last 4 digits of ssn, and first 2 letters of last name) to run the linkage process.

How to install

pip install healmatcher

How to use (example)

# Install package
!pip install healmatcher

# Load package
from healmatcher import hm

# create example dataset
testa = pd.DataFrame({
    'sex':[1,2,1,2,1,2,1,2,1,2],
    'dob':['2012-1-1','2011-12-1','1999-1-1','1998-11-1','2012-11-1','1984-1-1','1982-1-1','1975-1-1','1967-1-1','1954-1-1'],
    'ssn':[1111,2222,3333,4444,5555,6666,7777,8888,9999,1010],
    'ln':["as",'ss','zz','rr','ww','wa','tr','tt','hh','gq'],
    'PROVIDER_NUMBER':[2,1,1,1,1,1,1,1,2,1]
})
testb = pd.DataFrame({
    'sex':[2,2,1,1,1,2,1,2,1,1],

    'PROVIDER_NUMBER':[2,1,1,1,1,1,1,1,2,1]
