CPHQ Performance and Process Improvement 5

Question 1

A quality team is evaluating a new fall prevention protocol. After implementation, they want to determine if the improvement is sustained over 18 months. The BEST tool to monitor this is:

Accepted Answer

Control chart

Answer

Control charts track process performance over time and can detect whether improvements are sustained or if the process has shifted or regressed.

Question 2

The 'Define' phase of DMAIC primarily involves:

Accepted Answer

Clearly articulating the problem, scope, and project goals

Answer

The Define phase establishes the project charter, problem statement, scope, goals, and stakeholders before data collection begins.

Question 3

In a healthcare setting, 'process capability' refers to:

Accepted Answer

The ability of a process to consistently produce outputs within specified limits

Answer

Process capability measures how well a stable process performs relative to its specification limits, often expressed as Cp or Cpk indices.

Question 4

A quality improvement team identifies that patients frequently misunderstand discharge instructions. Using the '5 Whys' technique, they ask 'why' repeatedly. This method is BEST suited for:

Accepted Answer

Drilling down to the root cause of a problem through iterative questioning

Answer

The 5 Whys is a root cause analysis technique that iteratively asks 'why' to move from symptoms to underlying root causes of a problem.

Question 5

Which of the following BEST describes 'common cause variation' in a healthcare process?

Accepted Answer

Inherent, random variation that is expected within a stable process

Answer

Common cause variation is the natural, random variability inherent in any stable process and cannot be attributed to a specific assignable cause.
