Patient Safety, Quality Improvement, and Systems-Based Practice
Core concepts
Understand systems-based practice: how care is delivered across teams and settings, and how errors arise from systems rather than individuals. Know quality-improvement methods (Plan-Do-Study-Act, root cause analysis, failure mode and effects analysis) and metrics (structure, process, outcome). Recognize patient-safety hazards: medication errors, central line-associated bloodstream infections, ventilator-associated events, falls, and pressure injuries. Master handoffs (SBAR), checklists, and bundles. Understand reporting systems, just culture, and disclosure of errors.
Traps
Quality improvement is not the same as research - QI aims to improve local processes and does not always require IRB review, but ethical oversight may still apply. Root cause analysis focuses on systems, not blame. A single measure rarely captures quality; use balancing measures. Do not confuse a checklist with a guarantee - adherence matters.
Worked example
A unit notices rising central line infections. A team performs a root cause analysis, identifies inconsistent sterile technique and delayed line removal, and implements a bundle with daily line-necessity review. They track infection rates over time using a run chart. Rule of thumb: measure the process (bundle adherence) as well as the outcome (infection rate) to confirm improvement is real.
