The Role of a Nurse in Infection Control: Key Responsibilities and Impact

Infection control is a core nursing responsibility that extends across every healthcare setting where patients receive care. Nurses serve as the primary link between infection prevention policy and daily clinical practice, translating institutional guidelines into consistent bedside actions. This article defines the nurse's role in infection control, describes the specific duties that fall within nursing practice, and provides a practical framework that nurses can use to self-assess their infection control performance and identify areas for improvement.

The scope of this discussion covers hospital-based nursing, community and public health nursing, and specialized roles such as infection control nurses and infection control link nurses. The framework presented here applies to registered nurses, nursing students, and nurse leaders who supervise infection prevention activities. The evidence base draws from peer-reviewed literature on infection control nursing, including studies on link nurse programs, central line care, hand hygiene, and the organizational factors that shape nursing performance.

Defining the Nurse's Role in Infection Control

The nurse's role in infection control operates at three levels: direct patient care, unit-level coordination, and facility-wide program participation. At the direct care level, every nurse applies standard precautions, performs hand hygiene, maintains aseptic technique during procedures, and monitors patients for signs of infection. At the unit level, designated nurses may serve as infection control link nurses who bridge their clinical unit and the infection control department. At the facility level, specialized infection control nurses lead surveillance, outbreak investigation, education, and policy development.

A scoping review of infection control nurse literature published in 2024 examined 25 studies from January 2000 to December 2023 and identified themes related to the roles of infection control nurses, factors influencing their performance, and evaluation of infection control nurse programs. The review noted that infection control nurses make a significant contribution to limiting healthcare-associated infections, but it also highlighted a lack of high-quality evidence on infection control nurse programs and called for future research to map and design the structure, job responsibilities, and role of infection control nurses. This evidence gap means that many infection control nursing roles have developed through local practice instead of standardized national frameworks.

The complexity of infection control nursing has increased over recent decades. A 2009 article on changes in nosocomial infection control described how shorter hospital stays, healthcare delivery outside hospitals, growth in elderly patient populations, emerging diseases, multidrug-resistant pathogens, and accreditation requirements have all expanded the responsibilities of infection control nurses. These nurses now assume duties related to patient safety, healthcare quality, and tasks beyond traditional infection surveillance. The same article noted that professional organizations have argued that infection control staffing should be based not solely on the number of hospital beds but also on the complexity of the tasks involved, defined according to standardized criteria and infection control indicators.

Core Responsibilities of Nurses in Infection Prevention

Hand Hygiene and Standard Precautions

Hand hygiene is the single most important infection control action a nurse performs. A 2021 article on central line care and management stated that the single most crucial step a nurse can take to help prevent central line-associated bloodstream infections is performing proper hand hygiene. This principle extends to all patient care activities, beyond central line management.

Standard precautions apply to all patients regardless of their diagnosed infection status. These precautions include hand hygiene, use of personal protective equipment, safe injection practices, respiratory hygiene and cough etiquette, and proper handling of contaminated equipment and linens. Nurses apply standard precautions during every patient encounter, making these practices the foundation of infection prevention in healthcare.

A comparative cross-sectional survey conducted in Sweden examined hand hygiene knowledge and perceptions among nursing students and registered nurses during the COVID-19 pandemic in 2020 and in the post-pandemic period in 2023. The study used validated World Health Organization instruments and found that total knowledge scores did not differ significantly between the two time points. However, first-semester nursing students had lower knowledge of transmission routes compared to other groups. This finding suggests that hand hygiene education must begin early in nursing training and be reinforced throughout clinical practice.

Aseptic Technique and Invasive Procedure Care

Nurses are responsible for maintaining aseptic technique during invasive procedures and for the ongoing care of vascular access devices, urinary catheters, and surgical wounds. The 2021 central line article described the central line-associated bloodstream infection prevention bundle, which focuses on five key elements: hand hygiene, maximal sterile barrier precautions, chlorhexidine antiseptic, catheter site selection, and daily evaluation of the need for the device. Once a central venous access device is placed, evidence-based care and maintenance become the responsibility of the nurse. These interventions include dressing management, bathing practices, access of intravenous infusion sets, blood draws, and management of port line occlusions.

The same article emphasized that ensuring proper maintenance and care of a central venous access device falls within nursing practice and that these interventions can significantly reduce the patient's risk of central line-associated bloodstream infection. Central line-associated bloodstream infections occur in intensive care units and also in non-intensive care units, which means that nurses in general medical and surgical units must maintain the same standard of central line care as their critical care colleagues.

Surveillance and Monitoring

Surveillance is the systematic collection, analysis, and interpretation of infection data. Nurses contribute to surveillance through daily patient assessment, recognition of infection signs and symptoms, documentation of clinical findings, and reporting of suspected infections to the infection control team. The 1999 CDC Guideline for Prevention of Surgical Site Infection described surveillance as one of the key components of surgical site infection prevention, along with understanding the epidemiology, definitions, microbiology, and pathogenesis of these infections.

At the unit level, nurses monitor patients for postoperative wound infections, catheter-associated urinary tract infections, central line-associated bloodstream infections, and ventilator-associated pneumonia. This monitoring requires knowledge of infection definitions, ability to recognize early clinical signs, and consistent documentation practices. When a nurse identifies a possible infection, the next step is reporting to the appropriate authority, which may be the charge nurse, the infection control nurse, or the infection prevention committee.

Patient and Family Education

Nurses educate patients and families about infection prevention measures that continue after discharge. This education covers hand hygiene, wound care, recognition of infection signs, proper use of prescribed medications, and when to seek medical attention. Patient education is particularly important for surgical patients, patients with indwelling devices, and patients with chronic conditions that increase infection risk.

The education role extends to family members who provide care at home. Nurses teach families how to perform wound care, maintain clean environments, recognize early signs of infection, and prevent transmission of infections to other household members. This teaching must be tailored to the patient's health literacy level and cultural context to be effective.

The Infection Control Nurse Role

Specialized Responsibilities

Infection control nurses are specialized practitioners who coordinate infection prevention activities across healthcare facilities. Their responsibilities include developing and implementing infection control policies, conducting surveillance, investigating outbreaks, providing education and training, and consulting on infection prevention issues. The 2024 scoping review confirmed that infection control nurses make a significant contribution to limiting healthcare-associated infections, although the review also noted gaps in the evidence base for these programs.

A 2009 article described how infection control nurses are progressively assuming new responsibilities beyond traditional infection control, including ensuring patient safety, guaranteeing healthcare quality, and performing other tasks. This expansion reflects the growing complexity of healthcare delivery and the recognition that infection prevention is inseparable from overall patient safety.

Staffing and Program Considerations

The 2009 article also addressed staffing considerations for infection control programs. Professional organizations have voiced the opinion that staffing for infection control work should not be based solely on the number of hospital beds but also on the complexity of the tasks involved. Staffing should be defined according to standardized criteria and infection control indicators. The article further noted that the cost-benefit relationship of infection control programs should be demonstrated, which means that infection control nurses must be able to document the impact of their activities on infection rates and patient outcomes.

A 2026 study conducted in Oman assessed staff nurses' perceptions of the infection control team's role and the infection control environment across 18 public and private tertiary hospitals. The study surveyed 997 staff nurses and found that hospital affiliation, accreditation status, and availability of an infection control manual significantly predicted perceived infection control team competence. Nurses in private and accredited hospitals reported higher scores for both perceived infection control team role and perceived infection control environment. The study concluded that consistent infection control team practices, effective communication, hospital accreditation, and accessible infection control manuals strengthen infection control practices and patient safety.

The Infection Control Link Nurse Role

Purpose and Structure

Infection control link nurses are unit-based nurses who serve as a bridge between their clinical unit and the infection control department. A 2020 mixed-methods study of Dutch acute care hospitals found that link nurse programs were present in 67% of hospitals surveyed, with responsibility for 76% of these programs lying solely with the infection prevention and control team. The core component of most programs, reported by 90% of respondents, was education.

The Dutch study surveyed 72 infection control practitioners from 72 different hospitals and conducted interviews with four of these practitioners. Programs that included education on infection prevention topics and training in implementation skills were perceived as more effective than programs without such education or programs where education included only infection prevention topics. The interviews illustrated that these programs were initiated by the infection prevention team with the intention to collaborate with other departments to improve practice. Content for these programs was created at the time of their implementation, and infection control practitioners varied in their ability to express program goals and to engage experts and key stakeholders.

Core Competency Framework

A 2026 modified Delphi study conducted in China developed a core competency framework for infection control link nurses in general hospitals. The study began with a literature review that identified 18 documents published between 2008 and 2023, from which an initial framework of 141 indicators was developed. A panel of 23 experts then participated in two rounds of modified Delphi consultation, reaching consensus on a final framework comprising 5 domains, 19 subdomains, and 75 indicators.

The domains of infection prevention and control knowledge and skills received the highest mean importance scores in this study. In the second round of consultation, mean importance scores ranged from 4.04 to 4.96 on a five-point scale, coefficients of variation ranged from 0.04 to 0.20, and percent agreement ranged from 82% to 100%. This framework provides a structured approach to defining what infection control link nurses should know and be able to do, which can inform training programs and competency assessment.

Program Variation and Effectiveness

A 2018 systematic literature review examined strategies to promote infection prevention and control in acute care hospitals with the help of infection control link nurses. The review focused on identifying effective strategies for implementing link nurse programs and improving their impact on infection prevention practices. A 2010 article in Nursing Times discussed developing satellite roles within infection prevention teams to fulfill responsibilities, suggesting that link nurses represent one model for distributing infection prevention duties across clinical areas.

The 2020 Dutch study noted that infection control link nurse programs show considerable variation in content and setup. Programs with clear educational content are viewed as more successful by the infection control practitioners who implement them. This finding has practical implications for hospitals developing or improving their link nurse programs: education must be a central component, and it should include both infection prevention topics and implementation skills training.

The Nurse's Role in Surgical Infection Prevention

Preoperative Responsibilities

Nurses contribute to surgical site infection prevention during the preoperative period through patient assessment, preparation, and education. The 1999 CDC Guideline for Prevention of Surgical Site Infection described the pre-, intra-, and postoperative issues relevant to surgical site infection genesis. Preoperative nursing activities include assessing patients for infection risk factors, ensuring appropriate skin preparation, verifying that prophylactic antibiotics are administered at the correct time, and educating patients about preoperative bathing and postoperative wound care.

The guideline noted that approximately 75% of all operations in the United States are performed in ambulatory settings, which means that much of the preoperative preparation and postoperative follow-up occurs outside traditional inpatient units. Nurses in ambulatory surgery centers, outpatient clinics, and home health settings must therefore apply the same surgical site infection prevention principles as their operating room colleagues.

Intraoperative Responsibilities

Operating theatre nurses have specialized competence that is indispensable for patient safety during surgery. A 2020 discursive paper on operating theatre nurse specialist competence analyzed Swedish legal statutes and scientific articles and classified the content into the general six core competencies for healthcare providers. The paper found that the specialized operating theatre nurse is the only healthcare professional having the competence to be responsible for asepsis, instrumentation, infection and complication control, and management of biological specimens during the surgical procedure.

The paper emphasized that besides operating theatre nurses, no other healthcare profession has the formal education, competence, or skills to perform operating theatre nursing care during the surgical procedure. This finding underscores the critical role of operating theatre nurses in maintaining the sterile field, monitoring for breaks in aseptic technique, and ensuring that all equipment and supplies used during surgery are sterile and properly handled.

Postoperative Responsibilities

Postoperative nursing care focuses on wound assessment, incision care, and early recognition of surgical site infections. The 1999 CDC guideline described the postoperative issues relevant to surgical site infection genesis, including wound monitoring, dressing management, and patient education about signs of infection. Nurses must know the difference between normal postoperative inflammation and early infection, document wound appearance accurately, and escalate concerns promptly.

Postoperative education covers incision care, activity restrictions, nutrition, and when to contact the healthcare provider. Patients discharged from ambulatory surgery centers need clear instructions about wound monitoring and follow-up care. Home health nurses may continue this surveillance after discharge, making them important contributors to surgical site infection detection and prevention.

Infection Prevention in Specialized Settings

Computed Tomography and Radiology Settings

Infection prevention and control in radiology settings presents unique challenges. A 2024 Australian study examined infection prevention and control practices in computed tomography suites, focusing on intravenous contrast media administration and the use of power injectors. The study surveyed 160 participants, including 138 radiographers and 22 nurses, and found differences between public and private practice settings.

Public hospitals completed more contrast-enhanced scans and used dual injecting systems operated and cleaned by both radiographers and nurses. Private clinics generally used single-system power injectors. The study found that radiographers and nurses relied heavily on their colleagues and product guidelines for infection prevention and control information. Infection prevention and control teams were uncommon in private clinics but very common in public departments, and only 50% of respondents had undertaken infection prevention and control training in the last 12 months.

These findings highlight the importance of infection prevention training for nurses working in radiology and other specialized settings. Nurses in these settings must understand the infection risks associated with contrast administration, power injector use, and patient contact in imaging suites, and they must have access to current infection prevention guidance.

Community and Public Health Settings

Public health nurses serve as the frontline for disease prevention and control at the community level. A 2026 study conducted in Indonesia focused on the cross-cultural adaptation and psychometric evaluation of a dengue preventive attitudes questionnaire for public health nurses. The study surveyed 458 public health nurses working in primary healthcare units and found that the adapted questionnaire demonstrated acceptable validity and reliability for measuring public health nurses' attitudes toward dengue prevention.

The study's finding that assessing attitudes is essential because they influence the effectiveness of nursing practices in disease prevention applies broadly to community infection control. Public health nurses must maintain current knowledge of communicable disease prevention, apply this knowledge in community settings, and educate community members about infection prevention measures. Their attitudes toward prevention directly affect their willingness to implement prevention practices and to counsel patients and families effectively.

Emerging Infectious Disease Response

Nurses play a pivotal role in infection prevention during emerging infectious disease outbreaks. A 2026 cross-sectional study surveyed 193 nurses from three national and three public hospitals in South Korea to examine factors affecting infection control performance related to emerging infectious diseases. The study measured burnout, moral sensitivity, infection prevention environment, and infection control performance using validated self-report questionnaires.

The mean infection control performance score was 4.37 out of 5. Moral sensitivity and infection prevention environment significantly predicted infection control performance, explaining 37% of the variance. Burnout showed a negative correlation with infection control performance but was not a significant predictor in the regression model. The study concluded that interventions to enhance moral sensitivity and the institutional infection prevention environment are critical to improving infection control during emerging infectious disease outbreaks.

This finding has practical implications for nurse managers and hospital administrators. Creating a supportive infection prevention environment, which includes adequate supplies, clear policies, accessible training, and a culture that values infection prevention, directly improves nursing performance. Supporting nurses' moral sensitivity, which involves their ability to recognize and act on ethical concerns in patient care, also enhances infection control practices.

Barriers and Facilitators to Infection Control Adherence

Understanding Non-Adherence

Healthcare workers face multiple barriers to adhering to infection prevention and control guidelines. A 2020 rapid qualitative evidence synthesis conducted by Cochrane contributors examined barriers and facilitators to healthcare workers' adherence with infection prevention and control guidelines for respiratory infectious diseases. The review was prepared to inform the 2020 COVID-19 pandemic response and included qualitative and mixed-methods studies focusing on healthcare workers' experiences and perceptions.

The review noted that strategies in respiratory infection prevention guidelines include the use of personal protective equipment such as masks, face shields, gloves, and gowns, the separation of patients with respiratory infections from others, and stricter cleaning routines. These strategies can be difficult and time-consuming to adhere to in practice. The review emphasized that authorities and healthcare facilities need to consider how best to support healthcare workers to implement these strategies.

Common Barriers

Several categories of barriers to infection control adherence emerge from the literature. Time pressure is a consistent theme, as infection control practices add steps to already busy workflows. Inadequate supplies of personal protective equipment, hand hygiene products, and cleaning materials create practical obstacles to adherence. Unclear or conflicting guidance can confuse healthcare workers about which practices to follow. Physical discomfort from personal protective equipment, particularly during extended use, reduces adherence. Gaps in knowledge about transmission routes and appropriate precautions contribute to inconsistent practice.

Facilitators and Solutions

Facilitators of infection control adherence include adequate training, visible leadership support, accessible supplies, clear communication, and a positive safety culture. The Dutch link nurse study found that programs including education on infection prevention topics and training in implementation skills were perceived as more effective than programs without such education. This finding suggests that education alone is insufficient, nurses also need practical skills for implementing infection prevention practices in their specific clinical contexts.

The 2026 South Korean study found that the infection prevention environment significantly predicted infection control performance, explaining a substantial portion of the variance. This finding reinforces the importance of institutional support for infection prevention. Hospitals that provide adequate resources, maintain clear policies, and demonstrate organizational commitment to infection prevention enable their nurses to perform at higher levels.

Practical Framework for Daily Infection Control Practice

Self-Assessment Domains

Nurses can use the following framework to self-assess their infection control duties and identify areas for improvement. The framework organizes infection control responsibilities into five domains that align with the core competency framework developed for infection control link nurses in the 2026 Delphi study.

The first domain is infection prevention and control knowledge. This includes understanding transmission routes, standard and transmission-based precautions, infection definitions, and evidence-based prevention practices. Nurses should be able to explain why specific precautions are used for specific infections and how their actions prevent transmission.

The second domain is clinical skills. This includes hand hygiene technique, aseptic technique, personal protective equipment use, central line care, urinary catheter care, wound care, and safe injection practices. Nurses should be able to perform these skills consistently and correctly in daily practice.

The third domain is surveillance and monitoring. This includes daily patient assessment for infection signs, accurate documentation, recognition of infection trends, and reporting of suspected infections. Nurses should know the definitions of healthcare-associated infections and understand their role in surveillance activities.

The fourth domain is education and communication. This includes patient and family education, communication with the infection control team, collaboration with colleagues, and participation in unit-based infection prevention activities. Nurses should be able to teach patients about infection prevention and communicate concerns effectively.

The fifth domain is professional responsibility. This includes staying current with infection prevention guidelines, participating in training, following institutional policies, and contributing to a culture of safety. Nurses should take personal responsibility for their infection control practices and support their colleagues in maintaining high standards.

Daily Self-Assessment Questions

For each patient encounter, nurses can ask themselves the following questions. Did I perform hand hygiene at the correct moments? Did I use the appropriate personal protective equipment for this patient's precautions? Did I maintain aseptic technique during any invasive procedure? Did I assess this patient for signs of infection? Did I document my observations accurately? Did I educate the patient or family about any infection prevention measures relevant to their care?

At the unit level, nurses can ask additional questions. Are infection prevention supplies readily available in my work area? Do I know the current infection prevention policies for my unit? Have I received recent training on infection prevention topics? Do I know who to contact in the infection control team if I have concerns? Have I reported any suspected infections or infection control breaches?

Identifying Improvement Areas

After completing the self-assessment, nurses should identify specific areas for improvement. A nurse who struggles to recall the correct moments for hand hygiene may need to review the World Health Organization's Five Moments for Hand Hygiene. A nurse who is uncertain about central line dressing changes should seek additional training or supervision. A nurse who has not participated in infection prevention education recently should identify available training opportunities.

Nurses should also consider their unit's infection control performance. If infection rates are elevated, what factors might be contributing? Are there gaps in staff knowledge or skills? Are supplies adequate? Is there consistent adherence to precautions? Unit-based self-assessment can identify systemic issues that require attention from nurse managers and the infection control team.

Records and Measurements in Infection Control Nursing

Documentation Requirements

Accurate documentation is essential for infection control. Nurses document patient assessments, vital signs, wound appearance, invasive device care, medication administration, and patient education. This documentation serves multiple purposes: it supports clinical decision-making, provides data for surveillance, and creates a legal record of care provided.

Infection-specific documentation includes wound assessments with descriptions of appearance, drainage, and surrounding tissue, temperature and other vital sign trends, culture and sensitivity results, antibiotic administration records, and documentation of invasive device insertion and removal dates. Nurses must document the date of insertion for central lines and urinary catheters to support daily evaluation of the need for the device, as recommended in the central line bundle.

Surveillance Data Collection

Nurses contribute to surveillance through consistent documentation of infection-related events. The infection control team uses this data to calculate infection rates, identify trends, and evaluate the effectiveness of prevention interventions. The 1999 CDC guideline described surveillance as a key component of surgical site infection prevention, and the same principle applies to other healthcare-associated infections.

Unit-level surveillance data may include hand hygiene compliance rates, central line days, urinary catheter days, ventilator days, and infection rates per 1,000 device days. Nurses who document device presence and removal dates accurately enable the infection control team to calculate these rates correctly. Incomplete or inaccurate documentation undermines surveillance and can lead to incorrect conclusions about infection trends.

Quality Indicators

Infection prevention quality indicators include healthcare-associated infection rates, hand hygiene compliance, personal protective equipment adherence, and compliance with prevention bundles. The 2009 article on nosocomial infection control noted that professional organizations have called for staffing to be defined according to standardized criteria and infection control indicators. These indicators provide objective measures for evaluating infection control programs and identifying areas for improvement.

Nurses should understand the quality indicators relevant to their units and how their daily practices affect these measures. A nurse who performs hand hygiene consistently contributes to high compliance rates. A nurse who follows the central line bundle contributes to lower central line-associated bloodstream infection rates. Understanding the connection between individual practice and unit-level quality measures reinforces the importance of consistent infection control behavior.

Common Failure Patterns in Infection Control Nursing

Hand Hygiene Lapses

Hand hygiene lapses remain the most common failure pattern in infection control. These lapses occur when nurses miss indicated moments, use incorrect technique, or substitute gloves for hand hygiene. The 2021 central line article emphasized that hand hygiene is the single most crucial step for preventing central line-associated bloodstream infections, yet adherence rates in healthcare settings remain below desired levels.

Common reasons for hand hygiene lapses include high workload, forgetfulness, skin irritation from frequent washing, inaccessible hand hygiene products, and the perception that gloves eliminate the need for hand hygiene. The 2020 Cochrane review on respiratory infection guidelines noted that infection control strategies can be difficult and time-consuming to adhere to in practice, which applies to hand hygiene as well.

Breaks in Aseptic Technique

Breaks in aseptic technique during invasive procedures can introduce pathogens into sterile body sites. These breaks may occur during central line insertion or care, urinary catheter insertion, wound care, or medication preparation. The 2021 central line article described the five key elements of the central line bundle, and each element represents a potential point of failure if not followed consistently.

Common aseptic technique failures include inadequate skin antisepsis, failure to maintain a sterile field, touching sterile equipment with ungloved hands, and reusing single-use items. The 2020 discursive paper on operating theatre nursing noted that the operating theatre nurse is the only healthcare professional with the competence to be responsible for asepsis during surgical procedures, which underscores the specialized knowledge required for this role.

Incomplete Documentation

Incomplete or inaccurate documentation undermines infection surveillance and can delay recognition of infection trends. Nurses who fail to document device insertion dates, wound assessments, or patient education create gaps in the medical record that complicate care and surveillance. The 1999 CDC guideline emphasized the importance of surveillance for surgical site infection prevention, and surveillance depends on accurate clinical documentation.

Delayed Recognition and Reporting

Delayed recognition of infection signs or failure to report suspected infections can allow infections to progress and spread. Nurses must maintain vigilance for early signs of infection, including fever, increased drainage, redness, swelling, and changes in patient condition. When these signs are present, nurses must document their observations and report concerns to the appropriate clinicians and the infection control team.

Safety and Regulatory Context

Occupational Safety Considerations

Infection control practices protect both patients and healthcare workers. Nurses face occupational exposure to bloodborne pathogens, respiratory infections, and other infectious agents. The 2020 Cochrane review on respiratory infection guidelines noted that personal protective equipment such as masks, face shields, gloves, and gowns are key strategies for protecting healthcare workers during respiratory infectious disease outbreaks.

Nurses must use personal protective equipment correctly, participate in exposure prevention programs, and report occupational exposures promptly. Needlestick injuries, mucous membrane exposures, and other occupational exposures require immediate reporting and appropriate follow-up. Nurses should know their facility's exposure reporting procedures and post-exposure prophylaxis protocols.

Regulatory and Accreditation Requirements

Healthcare facilities must meet regulatory and accreditation requirements related to infection prevention. The 2009 article on nosocomial infection control noted that administrative requirements for accreditation have contributed to the increasing complexity of infection control. The 2026 Oman study found that accreditation status significantly predicted perceived infection control team competence, suggesting that accreditation processes support stronger infection control programs.

Nurses should understand the infection prevention standards that apply to their facilities and how their daily practices contribute to regulatory compliance. Surveyors may observe hand hygiene practices, assess knowledge of infection prevention principles, and review documentation. Consistent adherence to infection control practices supports both patient safety and regulatory compliance.

Professional Scope of Practice

Infection control responsibilities fall within the nursing scope of practice, but specific duties may vary by jurisdiction, setting, and role. The 2020 discursive paper on operating theatre nursing noted that the specialized operating theatre nurse has formal education, competence, and skills that no other healthcare profession possesses for operating theatre nursing care. Similarly, infection control nurses have specialized training that distinguishes their role from general nursing practice.

Nurses should understand the boundaries of their professional scope and seek appropriate consultation when situations exceed their competence. A staff nurse who identifies a potential outbreak should report to the infection control team instead of attempting to manage the situation independently. An infection control link nurse who identifies a systemic issue should escalate to the infection control department instead of attempting to change unit practices alone.

Professional Escalation Criteria

When to Report to the Infection Control Team

Nurses should report to the infection control team when they identify a suspected healthcare-associated infection, observe a breach in infection control practices that could harm patients, recognize a cluster of infections that may indicate an outbreak, or encounter uncertainty about appropriate precautions for a specific patient or situation.

Specific escalation triggers include a patient with a multidrug-resistant organism requiring transmission-based precautions, a surgical site infection that develops after discharge, a central line-associated bloodstream infection, a catheter-associated urinary tract infection, or any unusual clustering of infections on a unit. The 1999 CDC guideline described the importance of surveillance for identifying surgical site infections, and similar surveillance principles apply to other infection types.

When to Escalate to Nurse Leadership

Nurses should escalate to nurse leadership when they identify systemic barriers to infection control adherence, such as inadequate supplies, staffing shortages that compromise infection prevention, or persistent non-adherence by colleagues. The 2026 South Korean study found that the infection prevention environment significantly predicted infection control performance, which means that environmental barriers require leadership attention.

Nurse managers should be informed when infection control concerns involve resource allocation, policy implementation, or staff performance. A nurse who repeatedly observes colleagues skipping hand hygiene or failing to follow precautions should report these observations through appropriate channels instead of attempting to address the issue alone.

When to Seek External Consultation

External consultation may be appropriate when infection control concerns exceed local expertise or when outbreaks involve unusual pathogens. The 2024 scoping review on infection control nurses noted that these nurses play a significant role in limiting healthcare-associated infections, but the review also highlighted gaps in the evidence base for infection control nurse programs. In complex situations, consultation with public health authorities or infectious disease specialists may be necessary.

At a Glance: Nurse Infection Control Responsibilities

Implementation Steps for Improving Infection Control Practice

Step 1: Conduct a Personal Practice Audit

Begin by reviewing your current infection control practices against the five domains described in this article. Track your hand hygiene performance for one week, noting each time you miss an indicated moment. Review your documentation for completeness, particularly device insertion dates and wound assessments. Assess your knowledge of current infection prevention guidelines and identify gaps.

Step 2: Identify Specific Improvement Targets

Select one or two specific practices to improve instead of attempting to change everything at once. A nurse who identifies hand hygiene lapses might focus on the five moments for hand hygiene. A nurse who is uncertain about central line care might seek additional training. A nurse who has not participated in infection prevention education recently might identify available courses or workshops.

Step 3: Seek Training and Education

The 2020 Dutch link nurse study found that programs including education on infection prevention topics and training in implementation skills were perceived as more effective than programs without such education. Seek training that includes both content knowledge and practical implementation skills. This may include formal courses, unit-based education sessions, online learning modules, or supervised practice with an experienced colleague.

Step 4: Implement Changes in Daily Practice

Apply your learning in daily practice, focusing on consistent implementation instead of occasional compliance. Use reminders such as visual cues, checklists, or peer support to reinforce new practices. The 2021 central line article described the central line bundle as focusing on five key elements, and bundle approaches can be applied to other infection prevention practices as well.

Step 5: Monitor Progress and Seek Feedback

Track your performance over time and seek feedback from colleagues, supervisors, and the infection control team. The 2026 Delphi study on infection control link nurse competencies identified infection prevention and control knowledge and skills as the highest priority domains, which suggests that ongoing knowledge development should be a continuous focus.

Step 6: Contribute to Unit-Level Improvement

Share your learning with colleagues and participate in unit-based infection prevention activities. The 2020 Dutch study found that link nurse programs were initiated by the infection prevention team with the intention to collaborate with other departments to improve practice. Nurses at all levels can contribute to this collaboration by sharing observations, participating in education, and supporting colleagues in maintaining high standards.

Frequently Asked Questions

What is the difference between an infection control nurse and an infection control link nurse?

An infection control nurse is a specialized practitioner who coordinates infection prevention activities across a healthcare facility, including surveillance, outbreak investigation, education, and policy development. An infection control link nurse is a unit-based nurse who serves as a bridge between their clinical unit and the infection control department. The 2020 Dutch study found that link nurse programs were present in 67% of hospitals surveyed and that the core component of most programs was education. The 2024 scoping review on infection control nurses noted that these nurses make a significant contribution to limiting healthcare-associated infections, while the 2026 Delphi study developed a core competency framework for infection control link nurses that included 5 domains, 19 subdomains, and 75 indicators.

How does a nurse become an infection control nurse?

Becoming an infection control nurse typically requires registered nurse licensure, clinical experience, and specialized education or certification in infection prevention and control. The 2024 scoping review on infection control nurses noted a lack of high-quality evidence on infection control nurse programs and called for future research to map and design the structure, job responsibilities, and role of infection control nurses. This suggests that pathways into the role may vary by setting and jurisdiction. Nurses interested in this career path should seek information from professional infection control organizations and their facility's infection control department.

What are the five moments for hand hygiene?

The five moments for hand hygiene are before touching a patient, before clean or aseptic procedures, after body fluid exposure risk, after touching a patient, and after touching patient surroundings. The 2021 central line article stated that the single most crucial step a nurse can take to help prevent central line-associated bloodstream infections is performing proper hand hygiene. The 2026 Swedish study on hand hygiene knowledge found that first-semester nursing students had lower knowledge of transmission routes, which suggests that hand hygiene education must be reinforced throughout nursing training and practice.

How do nurses contribute to surgical site infection prevention?

Nurses contribute to surgical site infection prevention through preoperative assessment and preparation, intraoperative maintenance of asepsis, and postoperative wound monitoring and education. The 1999 CDC Guideline for Prevention of Surgical Site Infection described the pre-, intra-, and postoperative issues relevant to surgical site infection genesis. The 2020 discursive paper on operating theatre nursing noted that the specialized operating theatre nurse is the only healthcare professional having the competence to be responsible for asepsis, instrumentation, and infection control during the surgical procedure.

What should a nurse do if they suspect a healthcare-associated infection?

A nurse who suspects a healthcare-associated infection should document their observations, report to the patient's clinician, and notify the infection control team according to facility policy. The 1999 CDC guideline emphasized the importance of surveillance for identifying surgical site infections, and similar principles apply to other infection types. The 2024 scoping review on infection control nurses noted that these nurses play a significant role in limiting healthcare-associated infections, which means that reporting suspected infections to the infection control team supports their surveillance and prevention activities.

How does the infection prevention environment affect nursing performance?

The infection prevention environment significantly affects nursing performance. A 2026 cross-sectional study of 193 nurses in South Korea found that the infection prevention environment significantly predicted infection control performance, explaining a substantial portion of the variance. The study also found that moral sensitivity significantly predicted infection control performance. A 2026 study of 997 staff nurses in Oman found that hospital affiliation, accreditation status, and availability of an infection control manual significantly predicted perceived infection control team competence. These findings suggest that hospitals must provide adequate resources, clear policies, and organizational support to enable nurses to perform infection control effectively.

What training do infection control link nurses need?

Infection control link nurses need education on infection prevention topics and training in implementation skills. The 2020 Dutch study found that programs including both types of education were perceived as more effective than programs without such education or programs where education included only infection prevention topics. The 2026 Delphi study on infection control link nurse competencies identified infection prevention and control knowledge and skills as the highest priority domains. The 2024 Australian study on computed tomography settings found that only 50% of respondents had undertaken infection prevention and control training in the last 12 months, which suggests that ongoing training is not universal.

How do nurses support infection control during emerging infectious disease outbreaks?

Nurses support infection control during emerging infectious disease outbreaks through consistent application of precautions, patient assessment, education, and participation in facility response activities. The 2020 Cochrane rapid review on respiratory infection guidelines noted that healthcare workers' adherence to infection prevention and control guidelines becomes even more important during widespread respiratory infectious disease outbreaks. The 2026 South Korean study found that moral sensitivity and infection prevention environment significantly predicted infection control performance related to emerging infectious diseases, suggesting that both individual and institutional factors shape outbreak response effectiveness.
