Breaking Down Silos: Why the Future of Infection Prevention Depends on Interprofessional Collaboration

Healthcare-associated infections (HAIs) remain among the most persistent challenges facing modern healthcare. Despite decades of advancements in surveillance, environmental hygiene, antimicrobial stewardship, and infection prevention technologies, preventable infections continue to impact patient outcomes, healthcare costs, workforce safety, and organizational performance. One reason for this ongoing challenge is that infection prevention and control (IPC) efforts too often operate within professional and departmental silos. 

Infection prevention is not the responsibility of a single department, discipline, or individual. It is a shared responsibility that requires coordination among clinicians, environmental services professionals, facilities management teams, supply chain leaders, biomedical engineers, quality improvement specialists, executive leadership, and technology partners. To achieve sustainable reductions in infection risk, healthcare organizations must move beyond siloed approaches and embrace true interprofessional collaboration. The National Academies of Practice (NAP) provides a compelling model for accomplishing this.

The Cost of Working in Silos

Historically, infection prevention programs have often been viewed as the responsibility of infection preventionists and epidemiologists. While these professionals play a critical leadership role, the factors that influence the transmission of infection extend far beyond any single department. 

Consider the complex ecosystem that contributes to infection prevention outcomes:

• Clinical teams influence hand hygiene compliance, device utilization, and antimicrobial prescribing practices.
• Environmental services teams affect environmental cleanliness and disinfection effectiveness.
• Facilities and engineering professionals manage ventilation systems, airflow, filtration, and water-safety programs.
• Supply chain and value analysis leaders evaluate products and technologies that influence infection risk.
• Executive leaders set organizational priorities and allocate resources.
• Patients and families contribute to adherence, education, and safety.

When these stakeholders operate independently, opportunities for improvement are often missed. Communication gaps can delay interventions, duplicate efforts, create conflicting priorities, and reduce the effectiveness of evidence-based practices.

In contrast, organizations that foster cross-disciplinary collaboration are better positioned to identify risks, implement comprehensive solutions, and sustain long-term improvements. 

Infection Prevention Is a Systems Challenge

The COVID-19 pandemic underscored a critical lesson: infection prevention is fundamentally a systems issue. During the pandemic, healthcare organizations quickly recognized that no single profession could manage the complexities of emerging infectious threats. Effective responses required coordinated action across infectious disease physicians, nurses, respiratory therapists, environmental services professionals, facilities engineers, supply chain teams, occupational health specialists, and executive leaders. 

This systems-based approach remains essential today. For example, improving indoor air quality requires expertise from facilities management, engineering, infection prevention, clinical leadership, and environmental health professionals. Similarly, reducing surgical site infections requires collaboration among surgeons, perioperative nurses, sterile processing departments, supply chain teams, and infection prevention specialists. When healthcare organizations view infection prevention through an interprofessional lens, they shift from isolated interventions to integrated strategies that address the entire care environment.

The National Academies of Practice: A Model for Interprofessional Excellence

The National Academies of Practice serves as a national leader in advancing interprofessional healthcare collaboration. Founded on the principle that healthcare challenges are best addressed through multidisciplinary engagement, NAP brings together distinguished practitioners and scholars from a broad range of healthcare professions to improve healthcare delivery and outcomes.

NAP’s mission reflects a fundamental truth about healthcare quality and safety: no profession can achieve excellence alone. Through its interprofessional structure, NAP fosters collaboration among professionals in nursing, medicine, pharmacy, dentistry, respiratory therapy, physical therapy, occupational therapy, social work, healthcare administration, public health, and numerous other disciplines. This collaborative framework enables multiple perspectives to address complex healthcare challenges while promoting shared accountability for outcomes.

The organization’s emphasis on team-based problem-solving offers valuable lessons for infection prevention professionals. Rather than viewing infection prevention as the responsibility of a specialized department, NAP’s model encourages organizations to recognize it as an organizational priority that requires engagement across the continuum of care. This approach aligns with growing evidence that interprofessional teams improve communication, enhance patient safety, reduce errors, and support more effective implementation of evidence-based practices.

Air Quality: A Powerful Example of Collaborative Infection Prevention

One area where interprofessional collaboration is especially important is indoor air quality.

As healthcare organizations increasingly recognize the risks of airborne transmission, improving air quality has become a critical component of comprehensive infection prevention strategies. However, meaningful improvements require collaboration among multiple stakeholders.

Infection preventionists provide expertise in transmission dynamics and risk assessment. Facilities and engineering teams manage ventilation performance and filtration systems. Clinical leaders help identify high-risk areas in patient care. Environmental services teams support environmental controls and monitoring. Executive leaders provide strategic direction and funding.

Technologies such as advanced air decontamination systems can play an important role in reducing environmental bioburden, but their effectiveness depends on successful integration into broader organizational workflows and infection-prevention programs. Without cross-functional collaboration, even the most innovative technologies may not reach their full potential.

Building a Culture of Shared Accountability

Breaking down silos requires more than establishing multidisciplinary committees. It requires creating a culture in which every healthcare professional understands their role in preventing infections and in protecting patients.

Healthcare leaders can support this transformation by:

• Establishing interdisciplinary infection prevention councils.
• Including leaders from facilities, engineering, environmental services, and the supply chain in infection prevention planning.
• Creating shared quality and safety goals across departments.
• Encouraging collaborative problem solving and data sharing.
• Investing in education that fosters systems thinking and team-based care.
• Recognizing and rewarding collaborative achievements. 

When infection prevention is treated as a shared organizational priority rather than a departmental responsibility, healthcare organizations build stronger, more resilient safety cultures. 

Looking Ahead

The future of infection prevention will not be defined by any single intervention, technology, or profession. It will be defined by our ability to work together.

As healthcare systems face increasingly complex challenges, from emerging pathogens and antimicrobial resistance to evolving environmental risks, success will depend on dismantling traditional silos and embracing interprofessional collaboration.

The National Academies of Practice demonstrates what is possible when diverse healthcare professionals unite around a common mission. Their commitment to interprofessional excellence offers a valuable roadmap for infection prevention leaders seeking to improve patient safety, strengthen organizational resilience, and advance healthcare quality.

Infection prevention has never been a solo endeavor. Organizations that recognize this reality and foster meaningful cross-disciplinary collaboration will be best positioned to protect patients, support caregivers, and create safer healthcare environments for everyone.
