Healthcare organizations worldwide face mounting pressure to deliver exceptional patient care while managing costs and improving operational efficiency. The Improve phase, a critical component of the lean six sigma methodology, offers healthcare providers a structured approach to implementing meaningful clinical process improvements. This phase represents the transition from planning to action, where carefully designed solutions transform the way healthcare services are delivered.
Understanding the Improve Phase in Healthcare Context
The Improve phase follows the Define, Measure, and Analyze phases in the DMAIC (Define, Measure, Analyze, Improve, Control) framework of lean six sigma. By the time healthcare teams reach this stage, they have identified problems, collected relevant data, and analyzed root causes. The Improve phase challenges teams to develop, test, and implement solutions that address these underlying issues while maintaining patient safety as the top priority.

In healthcare settings, the stakes are considerably higher than in many other industries. Clinical process improvements must be implemented with extreme caution, as errors can directly impact patient outcomes. This reality makes the systematic approach of the Improve phase particularly valuable for healthcare organizations seeking to enhance quality while minimizing risk.

The Foundation: Building on the Recognize Phase
Before diving into improvements, healthcare teams must complete what many practitioners call the recognize phase. This preliminary stage involves acknowledging that a problem exists and securing organizational commitment to address it. During the recognize phase, leadership and frontline staff alike must understand the need for change and the potential impact of maintaining the status quo.

The recognize phase serves as the catalyst for improvement initiatives. Healthcare administrators might recognize patterns of medication errors, extended patient wait times, or inefficient resource utilization. This recognition, supported by data and stakeholder input, creates the foundation for subsequent improvement efforts. Without proper recognition of issues and organizational readiness, even the most well-designed improvements may face resistance or fail to achieve sustainable results.
Key Principles for Safe Implementation
Start with Small-Scale Testing
Healthcare organizations should never implement sweeping changes across entire departments or facilities without adequate testing. The Improve phase emphasizes pilot programs and small-scale trials that allow teams to identify potential problems before full deployment. A controlled testing environment provides valuable insights into how proposed changes affect workflow, staff satisfaction, and most importantly, patient safety.
For example, if a hospital aims to reduce medication administration errors through a new barcode scanning system, initial implementation might occur in a single unit. This approach allows staff to become familiar with the technology, identify technical glitches, and refine procedures before expanding to other areas.
Engage Frontline Healthcare Workers
Successful clinical process improvements require input from the individuals who interact with patients daily. Nurses, physicians, technicians, and support staff possess invaluable knowledge about practical challenges and potential unintended consequences of proposed changes. The Improve phase should include structured opportunities for frontline workers to provide feedback, suggest modifications, and participate in solution design.
This engagement serves multiple purposes. It improves the quality of solutions by incorporating practical insights, increases staff buy-in for changes, and helps identify safety concerns that might not be apparent to administrators or process improvement specialists.
Maintain Focus on Patient Safety
Every improvement initiative in healthcare must be evaluated through the lens of patient safety. Teams implementing changes should establish clear safety metrics and monitoring systems before, during, and after implementation. Any indication that a proposed improvement might compromise patient safety should trigger immediate reassessment and modification.
Risk assessment tools, failure mode and effects analysis (FMEA), and safety checklists help teams proactively identify potential hazards associated with process changes. These tools align perfectly with the systematic approach of lean six sigma and ensure that efficiency gains never come at the expense of patient wellbeing.
Practical Steps in the Improve Phase
Solution Generation and Selection
The Improve phase begins with generating potential solutions to address identified problems. Healthcare teams should encourage creative thinking while remaining grounded in evidence-based practices. Brainstorming sessions, benchmarking against other successful healthcare organizations, and reviewing medical literature can all inspire innovative approaches.
Once multiple solutions are identified, teams must evaluate each option based on criteria such as effectiveness, cost, implementation complexity, and potential impact on patient care. Multi-criteria decision analysis tools help teams objectively compare alternatives and select the most promising solutions for testing.
Pilot Testing and Refinement
Pilot testing represents the heart of the Improve phase in healthcare settings. During this stage, selected solutions are implemented on a limited scale while teams collect data on performance, identify problems, and make necessary adjustments. The pilot period should be long enough to reveal patterns and potential issues but short enough to maintain momentum.
Throughout pilot testing, teams should maintain open communication channels for reporting concerns and gathering feedback. Regular debriefing sessions allow staff to share observations and contribute to solution refinement. Data collected during pilots informs decisions about whether to proceed with full implementation, modify the approach, or return to the drawing board.
Creating Standard Operating Procedures
As improvements prove successful in pilot settings, teams must develop clear, comprehensive standard operating procedures (SOPs) for broader implementation. These documents should outline step-by-step processes, define roles and responsibilities, and provide guidance for handling exceptions or complications.
In healthcare, SOPs serve as critical tools for maintaining consistency and quality across shifts, units, and facilities. Well-written procedures reduce variability in care delivery and help new staff members quickly learn established processes. The lean six sigma approach emphasizes documentation as a key element of sustainable improvement.
Overcoming Implementation Challenges
Resistance to Change
Healthcare professionals often express skepticism about process changes, particularly when they have witnessed failed improvement initiatives in the past. Addressing this resistance requires transparent communication about the rationale for changes, evidence supporting proposed solutions, and mechanisms for ongoing feedback. Demonstrating early wins through pilot programs can help overcome skepticism and build momentum for broader implementation.
Resource Constraints
Healthcare organizations frequently operate under tight budgets and staffing limitations. The Improve phase must account for these realities by prioritizing solutions that offer the greatest impact relative to required resources. Lean six sigma principles emphasize eliminating waste and optimizing existing resources rather than assuming additional investments will solve every problem.
Competing Priorities
Clinical staff juggle numerous responsibilities, and process improvement initiatives compete for attention with direct patient care activities. Successful implementation requires protecting dedicated time for improvement work and integrating new processes seamlessly into existing workflows. Leadership support is essential for signaling that improvement efforts are organizational priorities worthy of staff time and attention.
Measuring Success and Preparing for Control
The Improve phase concludes by establishing metrics and monitoring systems that will continue into the Control phase. Healthcare teams should define specific, measurable indicators of success that align with original project goals. These might include reduced error rates, shorter patient wait times, improved patient satisfaction scores, or decreased resource utilization.
Baseline measurements from earlier phases provide comparison points for evaluating improvement effectiveness. Teams should set realistic targets that represent meaningful progress while remaining achievable given organizational constraints. Regular reporting on these metrics maintains visibility for improvements and sustains organizational commitment to new processes.
Conclusion
The Improve phase represents where healthcare organizations transform analysis into action, implementing clinical process improvements that enhance patient care while maintaining safety. By following lean six sigma principles, engaging stakeholders at all levels, and maintaining unwavering focus on patient wellbeing, healthcare providers can successfully navigate this critical phase. The journey from the recognize phase through improvement and ultimately to sustained control requires patience, persistence, and commitment to systematic methodology. However, the rewards of improved patient outcomes, enhanced efficiency, and empowered healthcare teams make this investment worthwhile for any organization committed to excellence in healthcare delivery.
