Health outcomes in the U.S.

Overview

Context

Cancer is the 2nd leading cause of death in the US over the last 75 years

Goal

To represent the differences in levels of cancer care across states

Approach

Interactive data visualization with RShiny package


Basis

Data source

Centers for Diseases Control and Prevention

National Cancer Institute

American Hospital Directory

68 Websites of Cancer Centers Designated by NCI

Data Manipulation

Use the number of beds of the hospital the cancer center affiliated to as the proxy of cancer center’s capacity

Data Genre

Annotated Chart

 

Outcome

Visualization techniques

  • Reference lines specifying the mean in bar chart

  • Fixed format data replacement: presenting the three information (number of patients, number of beds, bed-patient ratio)

  • Filtering to see specific states

Highlight and Innovation

  • Use shade of color to show patient ratio/number of hospitals/ratio of patient-hospitals in different states in a US map

  • Reduced Scope

  • Include incidence rate instead of mortality rate of cancer patients in different states

  • Include number of beds in each cancer center but not number of treatments
