The document discusses using Neo4j to analyze connections between payments made by pharmaceutical companies to physicians and prescription patterns of opioid drugs by those physicians. It combines data from CMS Open Payments on pharmaceutical payments to doctors, Medicare Part D data on prescriptions written by doctors, and DEA data on pill distribution, to determine if payments are correlated with increased opioid prescriptions. The analysis focuses on payments and prescribing patterns from 2013 to 2015.
