Automated Data Extraction

Optical character recognition used to automate review and identification process of patient medical charts


  • Manual review of patient medical charts was becoming too time and labor-intensive and was prone to errors. 
  • The client needed to automate the manual coding process in order to have more consistent and accurate results. 


  • The client needed to extract data from unstructured and nonstandard document formats including paper, fax and digital. We implemented optical character recognition technology for patient data extraction from the scanned medical charts which helped pull out relevant medical information. 
  • Integrated multiple data sources to automate the query process. 
  • Ran the extracted medical data through the NLP engine and captured the sentiment of a particular record.
