Implementing a change in pharmacy practice is an important milestone, but it is not the end of the safety journey. In fact, it is often just the beginning.
Under the Alberta College of Pharmacy’s Continuous Quality Improvement (CQI+) framework, pharmacies are expected not only to introduce improvements, but also to monitor, evaluate, and refine those changes over time. This ongoing learning is essential to building safer, more effective systems of care.
One of the most practical and widely used tools to support this process is the Plan-Do-Study-Act (PDSA) cycle.
When applied consistently, PDSA helps pharmacy teams move from one-time fixes to sustained, meaningful improvement.
Why Monitoring Change Matters in Pharmacy Practice
Pharmacy environments are dynamic. Staffing levels change, workloads fluctuate, and new medications, technologies, and services are introduced regularly. Even well-designed changes may not work exactly as expected once they meet real-world practice.
Monitoring change allows pharmacy teams to:
- Identify unintended consequences early
- Determine whether a change actually reduced risk
- Adjust processes before new issues emerge
- Reinforce learning across the team
Without evaluation, improvements risk becoming assumptions rather than evidence-based decisions.
Understanding the PDSA Cycle in a Practical Way
The PDSA cycle is a structured, repeatable approach to testing and refining change.
Plan involves identifying a specific change to test and defining what success looks like. In pharmacy practice, this might include adjusting a workflow, changing storage practices, or introducing a new documentation step.
Do involves carrying out the change on a small scale. This keeps the test manageable and reduces disruption to daily operations.
Study focuses on observing what happened. Did the change reduce incidents or close calls? Did it create new pressures or confusion? What feedback did staff provide?
Act involves deciding what to do next. The pharmacy may adopt the change, modify it, or abandon it based on what was learned.
In a healthy safety culture, this cycle does not stop after one round. It continues as systems evolve.
PDSA and Safety Culture Go Hand in Hand
A strong safety culture supports continuous learning rather than perfection.
When pharmacy teams feel safe to speak openly about what worked and what did not, PDSA becomes a powerful tool rather than a checkbox exercise. Staff are more likely to:
- Share observations honestly
- Report unintended consequences
- Suggest refinements based on daily experience
This openness helps ensure that improvements are realistic, sustainable, and aligned with actual workflow.
Bringing PDSA Into CQI Meetings and Huddles
PDSA works best when it is embedded into routine pharmacy activities, not treated as a separate project.
CQI meetings provide a natural forum to review recent incidents, discuss changes that were tested, and study emerging trends. Short staff huddles can be used to gather quick feedback on what is working or where challenges remain.
By incorporating PDSA into these discussions, pharmacies reinforce that improvement is an ongoing process rather than a one-time task.
Common Examples of PDSA in Daily Pharmacy Practice
A pharmacy may test a new approach to managing interruptions during verification, observe whether error rates change, and refine the process based on staff feedback.
Another pharmacy may adjust how look-alike medications are stored, monitor whether selection errors decrease, and further modify placement if confusion persists.
These small, iterative cycles often lead to more durable improvements than large, infrequent changes.
How PhIX Supports PDSA and Continuous Evaluation
PhIX (Pharmacy Incident Exchange) is designed to support the full CQI+ lifecycle, including the ongoing monitoring and evaluation of change.
PhIX allows pharmacy teams to document incidents and close calls in a structured way, making it easier to identify trends before and after changes are implemented.
Built-in contributing factor analysis supports the Study phase of PDSA by highlighting whether workflow, education, or medication-related risks continue to appear.
Trend dashboards help teams objectively assess whether a change is having the intended effect over time rather than relying on anecdotal impressions.
CQI meeting integration allows PDSA discussions, action items, and follow-up decisions to be captured in one place.
Role-based access supports inclusive team input while ensuring appropriate oversight by regulated professionals.
By centralizing learning and evaluation, PhIX helps pharmacies move beyond reactive fixes toward proactive system improvement.
Sustaining Improvement Over Time
The most effective CQI programs recognize that improvement is never finished. Policies, processes, and systems must evolve as practice changes.
The PDSA cycle provides a practical structure for this evolution, ensuring that learning continues even after initial changes are made.
When supported by a strong safety culture and the right tools, PDSA becomes part of how the pharmacy operates, not an added burden.
Key Takeaway for Pharmacy Teams
Change alone does not improve safety. Learning from change does.
By using the PDSA cycle to continuously evaluate new processes and by embedding these discussions into CQI meetings and huddles, pharmacies can build systems that are safer, more resilient, and better suited to real-world practice.
Tools like PhIX help make this process visible, measurable, and sustainable.
