Sales and Spending in the Health Care Industry

GeneralPayments_blog

Motivation

The recent release of data on payments made by drug and medical device companies to physicians and teaching hospitals provides for a unique opportunity to develop insights on trends in the health care industry. For example, what classes of drugs are heavily promoted? in what states are companies investing the most on promoting their products? how does industry spending on health care providers equate to sales within a region? These are just some of the questions that I believe can be answered from these disclosures.

Data in this analysis

The analysis outlined here utilizes the General Payments data for payments made to physicians and teaching hospitals, provided through the Open Payments website hosted by CMS, and covering the period January 2014 to December 2014. In addition, the analysis also includes data on total retail sales for prescription drugs in 2014 provided by the Henry J. Kaiser family foundation, and tables on state population and physician numbers per state for 2014 published by the Federation of State Medical Board. The following is a summary of the tables.
