Performance Improvement and Data Analytics Flashcards

A hospital notices its sepsis mortality rate is an outlier compared to peer institutions. Which analytic approach best identifies the root cause?

Answer: Multivariate regression controlling for patient acuity and treatment timing

Multivariate regression isolates independent contributors like acuity and timing from confounders, pinpointing actionable root causes.

Which statistical concept describes the natural, expected variation within a stable process?

Answer: Common cause variation

Common cause variation is inherent randomness in a stable process; it requires system-level redesign rather than individual case investigation.

A quality team wants to prioritize which of 15 improvement projects to tackle first. The MOST useful tool is:

Answer: Prioritization matrix weighing impact and feasibility

A prioritization matrix scores projects on criteria like impact and feasibility, enabling objective comparison across multiple options.

In healthcare analytics, 'data governance' primarily refers to:

Answer: Policies and standards that ensure data quality, security, and appropriate use across the organization

Data governance establishes the accountability, standards, and processes that guarantee data is accurate, secure, and used appropriately.

A leader reviews a p-chart showing the proportion of patients with hospital-acquired infections. The chart has a data point beyond the upper control limit. The FIRST action should be:

Answer: Investigate that specific time period for a special cause

A point beyond control limits signals special cause variation; investigation of that specific period is required before any intervention.

Which metric is MOST appropriate for measuring the reliability of a medication reconciliation process?

Answer: Percentage of patients with a completed reconciliation at each transition of care

Process reliability is best measured by the completion rate at each defined transition point, which reflects adherence to the intended workflow.

A Kaizen event differs from a traditional quality improvement project primarily because it:

Answer: Produces rapid incremental improvements over an intensive short-duration team session

Kaizen events bring a cross-functional team together for 3–5 days to implement improvements rapidly rather than over months-long project cycles.
