data-driven tool: a bar graph whose bars are drawn in decreasing order of frequency or relative
frequency; 80/20 (often 80% of the outcome results from 20% of the causes)
Histogram
data-driven tool: a vertical bar graph depicting a frequency distribution
Run Charts and Control Charts
data-driven tool: a run chart is a line graph with data plotted over time to identify variations (i.e.
commute to work, time taken to complete an abstract); control charts are run charts that include
control limits.
Scatter Plot Graph
data-driven tool: a graph of plotted points that show the relationship between two continuous variables
that do not depend on each other where the line is not connected. Independent (horizontal axis) and
dependent (vertical axis). (i.e. ODS cont ed hours vs number of abstracts completed)
-positive correlation looks like a slash (low left, high right), negative looks like a backward slash, and no
correlation is a jumble of dots
cause and effect diagram (fishbone diagram)
idea-driven tool - a diagram that relates a key performance problem (head) to its potential causes
(bones). Also called Ishikawa
Check Sheet
idea-driven tool - document occurrences of an event over time (i.e. central registry calling patients for
study)
Flow Chart
idea-driven tool - diagram of multi-step processes used to identify redundancies or delays; depicts a
starting and ending point and the steps between the two
The 3 Most Common Methods for Quality Improvement
PDSA/PDCA, DMAIC, Lean
Plan, Do, Study (Check), Act- rapid-cycle processes, performed repetitively in a short period of time
, Define, Measure, Analyze, Improve & Control- for larger projects in need of careful, thorough planning
Lean-reducing/eliminating waste (7 areas)
Quality Assurance (QA)
measures the accuracy of the data
Quality Improvement (QI)
examines the causes/processes behind the inaccuracies and the changes that can be implemented to
reduce errors
Central Registries - Flow
-Receive funding from and report data to either CDC NPCR, NCI SEER or both
-A registry is never required to enter into a data use agreement to share de-identified data, but the
registry may require the recipient to enter one to access files with disclosure risk
