55. Correlation

56. Correlation is NOT Causation

57. Living in a southern state doesn’t cause diabetes.
BUT it is a good clue about who needs help the
most.

58. None of us are immune…

61. Data Visualization
Summary Best Practices

62. Tables

63. Use a TABLE to:
Look up specific values
Compare specific values
Display precise values
Communicate more than one unit of
measure

88. Unplanned Hospital Readmissions
QUANTIFYING THE PROBLEM

89. The U.S. federal government has pegged the
cost of readmissions for
Medicare patients (65 and older) alone at
$26 billion annually
$17 billion
of it pays for unplanned readmissions that may
not happen if patients get the right care.

90. The overall readmission rate for those
65 and older in the U.S. is about
15% annually
and in New Zealand for the same
population it’s about
10% annually
