An effective infection prevention and control program involves interdisciplinary collaboration and communication, an accurate understanding of community risks and resources, and continual quality improvement efforts. To that end, infection preventionists will work with colleagues and organization leaders to plan, implement, and evaluate strategies to improve patient safety; reduce the risk of infection to patients, families, staff, and the communities served; ensure compliance with evidence-based practices and accreditation standards; and advance the delivery of high-quality infection prevention and control services. There are many approaches and strategies that can be used to achieve quality improvement. Tools include the plan, do, study, act cycle; gap analysis; root cause analysis; apparent cause analysis; failure modes and effects analysis; strength, weaknesses, opportunities, threats analysis; multivoting; goal-directed checklists; statistical process control and run charts; clinical practice guidelines; affinity diagrams; Pareto charts; Six Sigma and Lean methodologies; and various customer satisfaction metrics.
