Data Analysis and Visualization:  Medicare Case Study



In 2013, the Centers for Medicare and Medicaid Services (CMS) took the unprecedented step of publishing data about more than 3,000 hospitals for the 100 most common inpatient procedures. One of our senior scientists, Elena Popovici, has analyzed this data and built a set of interactive data exploration tools. Elena gave a presentation of the analysis and visualization methodology, as well as the intriguing insights, to a joint meeting of the Vancouver DataScience, R Users and Machine Learning meetup groups. Download the slides, play back the recordings, or explore using the interactive visualizations.  Have questions? Contact Elena.

Where Are Hospitals Needed? 



Discover how Medicare-billed discharges for a diagnosis-related group (DRG) are distrbuted across the US and how this compares to the number of hospitals providing treatment for a DRG. See how this comparison changes when the states' Medicare population is taken into account.

How Do States Compare in Providing Treatment? 



Discover how different states compare with respect to number of Medicare discharges and number of hospitals providing treatment in relation to the states' Medicare population. See which states have the most overall discharges per Medicare capita and which states stand out for the most psychoses or alcohol and drug abuse discharges.

How are Specialized and Generalized Hospitals Distributed Across States?



Discover how many specialized and generalized hospitals are in each state. See which which diagnosis-related groups (DRGs) are treated in each type of hospital.  See which states have no specialized hospitals.

How Are Hospitals Specialized for Specific Diseases?

Discover the degree to which hospitals specialize in certain diagnosis-related groups (DRGs). See which generalized hospitals treat more than half of their discharges for psychoses. See what is the most prevalent DRG treated in a specialized hospital.
