Origins of PDCA
The Plan-Do-Check-Act (PDCA) cycle, also known as the Deming Cycle, is a foundational quality improvement model that supports iterative, incremental change. It is one of the most frequently tested improvement frameworks on the RHIA exam.
Plan
In the Plan phase, teams identify the problem, gather baseline data, and develop a hypothesis for improvement. A clear, measurable objective is established before any change is implemented.
Do
The Do phase involves implementing the planned change on a small scale, such as a single unit or department, to test its effectiveness before wider rollout. Small-scale testing reduces risk and allows for quick adjustments.
Check (Study)
During the Check or Study phase, teams compare results against the original objective and baseline data. This analysis determines whether the change produced the intended improvement or unintended consequences.
Act
In the Act phase, teams decide whether to adopt the change permanently, adapt it based on lessons learned, or abandon it altogether. Successful changes are standardized and spread to other areas of the organization.
Rapid Cycle Improvement
PDCA cycles can be repeated rapidly, sometimes within days, allowing organizations to test multiple small changes quickly rather than waiting for a single large-scale implementation. This rapid cycle approach reduces the risk of large failed initiatives.
Documentation and Sustainability
Thorough documentation of each PDCA cycle, including what was tested, the results, and the decisions made, ensures institutional knowledge is retained and improvements are sustained over time through updated policies and training.
Healthcare Example
A HIM department might use PDCA to test a new chart deficiency notification process on one nursing unit before expanding it hospital-wide.
