Quality Improvement

Question 1

Name 5 characteristics of a complex healthcare system that increase the risk of error.

Answer 1

Workplace design, staffing (e.g., scheduling problems), integration of care across multiple settings, limited resources, and variability in workplace culture (i.e., “blame” vs. “just” culture)

Question 2

What’s the difference between a “blame” culture and a “just” culture?

Answer 2

Blame Culture assigns fault to individuals and discourages reporting. Just Culture treats errors as system failures, encourages reporting, and focuses on learning.

Question 3

What are two behaviors characteristic of a culture of improvement?

Answer 3

Always measuring performance and changing processes that aren’t meeting desired outcomes.

Question 4

Define “variation” and why reducing unwanted variation matters in QI.

Answer 4

Variation is the degree of uncertainty in the outcomes of a process

Reducing unwanted variation improves patient outcomes by making care more consistent

Question 5

Explain the relationship between standardization and reliability.

Answer 5

Standardization is the process by which variation is reduced (through changes to policy and care delivery)一it increases Reliability, which is the ability of a process to perform consistently (a “test” of variation reduction, if you will)

Question 6

What are PDCA and PDSA, and what do the letters stand for in each?

Answer 6

Specific models for QI that involve structured approaches to testing and implementing change一Plan, Do, Check (or Study), Act

Question 7

What are the four measures of QI? Provide an example of each.
*

Answer 7

Structure (how care was delivered to patient), Process (what was done to patient), Outcome (what happened to patient), and Balance (whether improvements in one area cause harm in another一e.g., increased bedside rounding time leading to longer clinic wait times)

Structure: nurse to patient ratio; Process: % of heart failure patients with follow up scheduled before discharge; Outcome: 30 day readmission rate

Question 8

What does a run chart show and when is it used?

Answer 8

Line graph showing how a metric changes over time; used to visualize trends and detect nonrandom changes after an intervention.

Question 9

How does a control chart differ from a run chart?

Answer 9

Adds statistical control limits to identify special-cause variation versus “regular” variation; helps determine whether observed changes are statistically significant (i.e., fall outside control limits)

Question 10

List 5 essential principles of change management for successful QI implementation.

Answer 10

Leadership alignment, clear vision and communication, employee training, feedback mechanisms (e.g., regular data review), success celebration
