A data extraction algorithm for assessment of contraceptive counseling and provision

Data extraction algorithms can be used effectively for computer-aided chart review of contraception counseling and provision measures, but testing and refinement are extremely important. Search-term capture from unstructured data is a critical component of a comprehensive algorithm, especially for the capture of instances of contraception counseling without provision. The algorithm that we developed here could be used by others with an electronic medical record system who are interested in real-time assessment, quality improvement, and comparative study of the delivery of contraceptive services. The ease of execution of this algorithm also allows for its repeated use for ongoing assessments over time.
