Emerging infectious diseases impact healthcare providers in the United States and globally. Nurses play a vital role in protecting the health of patients, visitors, and fellow staff members during routine practice and biological disasters, such as bioterrorism, pandemics, or outbreaks of emerging infectious diseases. One vital nursing practice is proper infection prevention procedures. Failure to practice correctly and consistently can result in occupational exposures or disease transmission. This article reviews occupational health risks, and pharmacological and nonpharmacological interventions for nurses who provide care to patients with new or re-emerging infectious diseases. Infection prevention education based on existing infection prevention competencies is critical to ensure adequate knowledge and safe practice both every day and in times of limited resources. Challenges specific to infectious disease disasters are discussed, as well as the role of microorganisms and nurse education for infection prevention.

Nurses play a vital role to protect the health of patients, visitors, and fellow staff members during routine practice and biological disasters... New or re-emerging infectious diseases contribute to, but are not the sole cause of, infectious disease morbidity and mortality worldwide. In the United States (U.S.) and globally, infectious diseases are the third leading cause of death (Heron, 2016). Nurses play a vital role to protect the health of patients, visitors, and fellow staff members during routine practice and biological disasters, such as bioterrorism, pandemics, or outbreaks of emerging infectious diseases. Failure to implement correct infection prevention practices can result in healthcare-associated disease transmission and occupational exposure for healthcare personnel, and can impact the health of communities.
Impact of New or Emerging Infectious Diseases
Multiple new diseases have been identified... [and] multiple existing infectious diseases have re-emerged or resurged, causing large outbreaks. New or re-emerging infectious diseases can have a huge impact on morbidity, mortality, and costs to the affected region, and pose a significant challenge to healthcare and public health systems. Multiple new diseases have been identified during the past twenty years, including severe acute respiratory syndrome corona-virus (SARS Co-V), Middle East respiratory syndrome corona-virus (MERS Co-V), and novel strains of avian and swine influenza. In addition, multiple existing infectious diseases have re-emerged or resurged, causing large outbreaks. Two recent examples include Zika and Ebola. The Zika virus has caused disease in more than 28 countries and is associated with severe birth defects, such as microcephaly (Cauchemez et al., 2016). The 2014 Ebola virus outbreak infected almost 30,000 individuals and resulted in more than 11,000 deaths worldwide (CDC, 2016a).
Healthcare providers have increasingly been challenged by the increase in multi-drug resistant organisms (MDRO), in particular antibiotic-resistant bacteria; at least 2 million are infected and 23,000 die each year in the States United States from MDROs (Centers for Disease Control and Prevention [CDC], 2013). Individuals infected with MDROs are more likely to die from their infection than those infected with a pathogen that is not drug resistant (CDC, 2013). Healthcare-associated infections (HAI) due to more common pathogens, such as Staphylococcus, also contribute to routine infectious disease morbidity and mortality. Approximately 722,000 individuals are infected and 75,000 will die from an HAI each year in U.S. hospitals (CDC, 2016b).
In addition to the ongoing risk of an outbreak from a new or emerging infectious disease, and the challenges posed by commonly encountered infectious diseases, there is also the perpetual risk of intentional use of a biological agent in the form of a bioterrorism attack. Bioterrorism poses unique challenges to healthcare providers and public health, because the pathogens are rare, they often lack a vaccine or efficacious anti-infective therapy, and a covert attack would be very difficult to detect (Rebmann, 2014).
Outbreaks of SARS Co-V, MERS Co-V, and Ebola have all involved extensive spread in hospitals, both within the United States and globally. Single cases of a new or emerging disease, or an infectious disease outbreak, whether naturally occurring or man-made, challenge healthcare providers and public health systems. Disease transmission can occur within the community, and settings in which young children or elderly persons congregate are most likely to be involved. For example, childcare agencies (de Perio, Wiegand, & Evans, 2012), schools (Chao, 2010), and long-term care facilities (Murray et al., 2016) are likely sites for infectious disease transmission during routine times as well as during outbreaks. Disease transmission can also occur in any setting where healthcare is delivered, especially in hospitals where high consequence opportunities exist including use of invasive devices and therapeutic interventions. Outbreaks of SARS Co-V (Webb, Blaser, Zhu, Ardal, & Wu, 2004), MERS Co-V (Park et al., 2016), and Ebola (Dunn et al., 2016) have all involved extensive spread in hospitals, both within the United States and globally.
One important aspect of nursing practice is the proper use of infection prevention procedures. Infection prevention practices can limit disease transmission and occupational exposures when implemented consistently and correctly. However, researchers have found that many healthcare personnel do not consistently implement infection prevention measures correctly (Assiri et al., 2013; Rebmann, Carrico, & Wang, 2013; Shigayeva et al., 2007). This article reviews the role of infection prevention when nurses provide care to patients with new or re-emerging infectious diseases as a means of limiting healthcare-associated disease transmission and preventing occupational exposure.
Occupational Health Risk for Nurses
Healthcare personnel had significantly higher risk of infection than non-healthcare individuals during the 2014 Ebola outbreak and 2003 SARS Co-V outbreak. Nurses are at risk of occupational exposure to life-threatening infectious diseases when providing care to individuals infected with new or emerging pathogens. Healthcare personnel had significantly higher risk of infection than non-healthcare individuals during the 2014 Ebola outbreak (Evans, Goldstein, & Popova, 2015) and 2003 SARS Co-V (Health Canada, 2003) outbreak. For example, in Sierra Leone, Africa, the Ebola infection rate was 103-fold higher among healthcare personnel compared to non-healthcare workers (Kilmarx et al., 2014). Two of the four U.S. Ebola-infected cases were healthcare personnel who were exposed while providing care to an imported case (CDC, 2014a). In Canada, approximately half of all SARS Co-V cases consisted of healthcare personnel who had been exposed through patient care activities (Webb et al., 2004). Healthcare workers have also been found to be at high risk of infection from MERS, especially during healthcare-based outbreaks (Chung-Jong Kim, In press).
Pharmacological Intervention Availability and Efficacy
Pharmacological interventions (e.g., anti-infective therapy, chemoprophylaxis, and vaccination) are likely of varying and potentially limited use during a bioterrorism attack, outbreak of a new or emerging pathogen, or a pandemic. Of these, chemoprophylaxis is most likely to aid in minimizing morbidity and mortality for bioterrorism or a pandemic. Efficacious regimens have been identified for use as post-exposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP) for many potential bioterrorism agents and could be used during an influenza pandemic (Rebmann, 2014).
However, new or emerging infectious diseases are significantly less likely to have a known efficacious chemoprophylaxis identified... However, new or emerging infectious diseases are significantly less likely to have a known efficacious chemoprophylaxis identified; there is little to no research regarding the effectiveness of existing antibiotics or anti-virals against emerging pathogens. For example, there is currently no known prophylaxis for Ebola, Zika, SARS CoV, or MERS CoV. In addition, though effective PEP and PrEP have been identified for some infectious diseases, researchers have reported that the United States lacks sufficient stockpiles of medication to provide mass PEP or PrEP (Rebmann, Wilson, LaPointe, Russell, & Moroz, 2009; U.S. Department of Health and Human Services [U.S. DHHS], 2013).
Vaccination is one of the most effective infection prevention interventions and is critical to limit disease transmission and protect nurses from illness during routine times. Current CDC guidelines list vaccines relevant for healthcare personnel as a means of protecting the worker from illness and preventing transmission from the healthcare professional to patients and others (Advisory Committee on Immunization Practices, 2011). These recommendations stress the need for immunization against hepatitis B, measles, mumps, rubella, and varicella as well as a one-time dose of Tdap [tetanus, diphtheria, pertussis), and an annual influenza immunization. Additional vaccines are also recommended for healthcare personnel who have special circumstances with respect to work responsibilities and exposure risk, such as provision of meningococcal vaccine for laboratory personnel who may be routinely exposure to Neisseria meningitidis during specimen handling or processing.
During a bioterrorism attack, outbreak of a new or emerging pathogen, or a pandemic, vaccination may have a limited role. During a bioterrorism attack, outbreak of a new or emerging pathogen, or a pandemic, vaccination may have a limited role. Many potential bioterrorism agents do not have a vaccine; the vaccine is only Food and Drug Administration (FDA)-approved for laboratory personnel (e.g., tularemia); or it is not FDA-approved for PEP use (i.e., anthrax) (Rebmann, 2014). None of the most severe or deadly emerging infectious diseases, including SARS Co-V, MERS CoV, or Zika, currently have an effective vaccine. However, vaccine may be available during a future pandemic, depending upon the influenza strain that emerges. Various pre-pandemic vaccines have been created, but may provide limited protection depending upon cross-reactivity to the circulating pandemic strain (Rebmann & Zelicoff, 2012).
Seven to ten month delays in vaccine release have been experienced during past pandemics (Lagace-Wiens, Rubinstein, & Gumel, 2010). If a completely novel influenza strain emerged into a pandemic, there would be need to develop a new vaccine. Such a vaccine would be expected to have a delayed and staggered release that will leave many nurses at risk from infection until six or more months after the novel strain is identified (Haaheim, Madhun, & Cox, 2009; Rebmann & Zelicoff, 2012).
... it will be critical that nurses follow the PEP or PrEP regimen correctly and/or receive the event-specific vaccine to protect themselves from disease. If pharmacological interventions are available during a bioterrorism attack, outbreak of an emerging infectious disease, or a pandemic, nurses could protect their patients, their families, and themselves if they take or receive the medication/vaccine as recommended. Post-exposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP) could involve taking anti-virals for up to six weeks at a time (U.S. DHHS, 2013) and vaccine could be released off-label or under an emergency authorization usage format, meaning non-FDA-approved (Rebmann & Zelicoff, 2012). Despite this, it will be critical that nurses follow the PEP or PrEP regimen correctly and/or receive the event-specific vaccine to protect themselves from disease (U.S. DHHS, 2013). Of concern, this did not occur during the 2009 pandemic, during which healthcare personnel had very poor uptake of the H1N1 vaccine (Rebmann, Wright, Anthony, Knaup, & Peters, 2012; Rebmann & Zelicoff, 2012), and low compliance may have contributed to morbidity and mortality among patients.
Non-Pharmacological Interventions to Manage Potentially Contagious Patients
Non-pharmacological interventions (NPI) are more likely than pharmacological interventions to be available and useful during an outbreak... In addition to pharmacological interventions during a bioterrorism attack, outbreak of an emerging infectious disease, or a pandemic, nurses should implement protective measures that do not involve a pharmaceutical product to limit disease spread. Non-pharmacological interventions (NPI) are more likely than pharmacological interventions to be available and useful during an outbreak of an emerging infectious disease, pandemic, or bioterrorism attack (Rebmann, 2014).
NPIs include surveillance; standard precautions and isolation; use of personal protective equipment (PPE); hand hygiene; quarantine; environmental disinfection; and social distancing. Studies have indicated that NPIs can minimize morbidity and mortality when implemented correctly and consistently (Bell, 2006a; 2006b). Nurses should be familiar with the NPIs most appropriate to their scope of practice during a biological event; namely, surveillance, standard precautions and isolation, PPE usage, and hand hygiene. This section will discuss these in more detail below.
Surveillance
During the SARS Co-V outbreak in Canada, it was estimated that 10 healthcare workers were infected for every day that a symptomatic, infected individual was not placed in isolation. Identifying individuals who are potentially contagious, or surveillance, is a vital nursing practice. When contagious individuals are not identified, they are not placed in isolation and this omission can lead to disease transmission between patients within healthcare facilities (Banach, Bielang, & Calfee, 2011). During outbreaks of emerging infectious diseases, failure to correctly identify contagious individuals can affect not only other patients, but healthcare personnel as well. During the SARS Co-V outbreak in Canada, it was estimated that 10 healthcare workers were infected for every day that a symptomatic, infected individual was not placed in isolation (Health Canada, 2003). An epidemiological study conducted over three months in a single hospital emergency department during the 2009 H1N1 pandemic found that there were 179 unprotected staff exposures due to failure to identify and isolate symptomatic patients (Banach et al., 2011).
Theoretically, these staff exposures and illnesses could have been prevented if healthcare personnel had correctly identified contagious patients and isolated them quickly and appropriately. Failure to identify contagious patients was also associated with healthcare personnel infections during the Ebola outbreak (Kilmarx et al., 2014).
Standard Precautions and Isolation
One basic tenet of infection prevention is the use of standard and transmission-based precautions (i.e., isolation) both in inpatient and outpatient settings (Siegel, Rhinehart, Jackson, Chiarello, & Health Care Infection Control Practices Advisory, 2007). In addition to providing guidelines for isolating potentially contagious individuals, the 2007 CDC isolation guidelines address respiratory hygiene practices; the challenges of managing patients infected with emerging pathogens; multidrug-resistant organisms; environmental controls; and safe injection practices (Siegel et al., 2007). The revised guidelines also emphasize the importance of isolating individuals suspected of having a contagious illness/condition rather than waiting for laboratory confirmation for disease presence (Siegel et al., 2007).
...researchers have found that healthcare personnel often demonstrate low compliance with standard and transmission-based precautions. Despite the widespread dissemination of these guidelines and incorporation into healthcare policies and procedures, researchers have found that healthcare personnel often demonstrate low compliance with standard and transmission-based precautions. For example, only 16% of nurses from a community hospital reported that they always follow contact precautions correctly (Jessee & Mion, 2013). Observation studies have found only 22% of healthcare personnel were compliant with respiratory hygiene and 60-75% with isolation precautions (Manian, 2007; Martel et al., 2013; Weber et al., 2007).
Failure to identify potentially contagious individuals is a common cause of non-compliance with isolation (Banach et al., 2011; Health Canada, 2003; Kilmarx et al., 2014). However, incorrect use of PPE and failure to perform hand hygiene are other forms of isolation non-compliance that lead to disease transmission and occupational exposure (Bledsoe et al., 2014; Casalino et al., 2015). Self-reported and observed behaviors have been found to differ significantly in terms of compliance with isolation practices; studies have found that self-reported compliance is high while actual observed practice demonstrates low compliance (Jessee & Mion, 2013; Martel et al., 2013). For this reason, researchers recommend that isolation compliance be monitored via direct observation, though this can be resource-intensive (Ross et al., 2011).
Personal Protective Equipment
Improper use of PPE can result in auto-inoculation during use or removal, which can lead to infection. A critical component of standard and transmission-based precautions is the use of PPE. Recommendations regarding correct selection and use of PPE are outlined in the 2007 CDC isolation guidelines (Siegel et al., 2007). Multiple types of PPE are available for use in healthcare settings, including non-sterile and sterile gloves; impervious and non-impervious gowns; masks; and eye protection. Higher levels of respiratory protection, such as respirators, are also included as PPE (Siegel et al., 2007). Various professional organizations, associations, and governmental agencies have outlined procedures for donning and doffing PPE using multiple types of training materials that include graphics, photos, step-by-step written instructions, and multimedia videos. The CDC has developed extensive educational programs related to PPE use specific to Ebola due to recommendations to use additional items not regularly used for isolation precautions, such as boots, impervious gowns, aprons, full body suits, and hoods (CDC, 2015).
Despite these tools and resources, compliance with PPE has been found lacking among healthcare personnel and these lapses have been associated with occupational exposures and illness (Kilmarx et al., 2014). Researchers have found that fewer than 15% of healthcare personnel were able to correctly don and doff PPE needed to provide care for Ebola patients (Beam, Gibbs, Boulter, Beckerdite, & Smith, 2011). Studies examining glove use have found that about 60% of healthcare personnel wore gloves when the task required it (Bledsoe et al., 2014; Hitoto et al., 2009). An observation study examining compliance with contact isolation found that only 76% of healthcare personnel donned a gown for each patient encounter (Manian, 2007).
...even after three training sessions, half of all medical and nursing students made critical errors when removing PPE. Even education interventions have not supported compliance close to 100%. One study found that PPE compliance improved from 44% to only 69% after an education intervention (Allen & Cronin, 2012). Casalino et al. (2015) reported that, even after three training sessions, half of all medical and nursing students made critical errors when removing PPE. One possible reason why most past training interventions have not resulted in positive long-term outcomes is that they have not been competency-based programs, or only utilized verbal education versus incorporating simulation, role playing, or the use of standardized patients. A more recent study found no self-contamination of skin or clothing after healthcare personnel were provided CDC-standardized Ebola PPE education coupled with simulation (Casanova et al., 2016). Additional studies need to examine the impact of other competency-based curricula on PPE compliance.
Improper use of PPE can result in auto-inoculation during use or removal, which can lead to infection. Healthcare personnel who did not wear PPE consistently or correctly were found at significantly higher risk of MERS Co-V infection, compared to healthcare workers who had better PPE compliance (Chung-Jong Kim, In press). Researchers reported similar findings during the 2003 SARS Co-V outbreak. Approximately half of all individuals infected with SARS Co-V in Canada were healthcare personnel infected through occupational exposures, most believed to be related to improper removal of respirators (Health Canada, 2003; Moore, Gamage, Bryce, Copes, & Yassi, 2005). Improper use of PPE was also associated with Ebola infection among healthcare personnel (Kilmarx et al., 2014).
Hand Hygiene
Performance of patient care with clean hands has been a foundational element in nursing care since the birth of the profession. Performance of patient care with clean hands has been a foundational element in nursing care since the birth of the profession. Guidelines outlining when, how, and under what circumstances to perform a soap and water hand wash versus an alcohol-based hand rub have been published by the CDC (Boyce & Pittet, 2002). Monitoring hand hygiene to track compliance rates has been a common occurrence in healthcare settings and has involved multiple healthcare disciplines.
Hand hygiene is critical to the prevention of infection transmission. However, rates of compliance with hand hygiene guidelines remain low. For example, a study of emergency medical services personnel found that 28% of staff performed hand hygiene when indicated (Bledsoe et al., 2014). Hand hygiene compliance was found to be between 40–53% among triage nurses in an emergency department (Martel et al., 2013). Healthcare agencies should continue to educate healthcare personnel regarding proper hand hygiene, monitor compliance, and intervene when incorrect practice is identified.
Challenges Specific to Infectious Disease Disasters
Infectious disease disasters... pose unique challenges to following stringent infection prevention. Implementing infection prevention practices correctly and consistently is difficult even during routine times. Infectious disease disasters (e.g., bioterrorism, outbreaks of an emerging infectious disease, and pandemics) pose unique challenges to following stringent infection prevention. These events are often associated with an influx of potentially contagious individuals, resulting in healthcare surge and a shortage of medical supplies, including hand hygiene products and PPE, and isolation areas (Kilmarx et al., 2014; Rebmann, 2014). Several of these challenges are discussed briefly below, including shortages of PPE, staffing challenges, and changing recommendations.
Insufficient PPE
During the 2014 Ebola outbreak, PPE availability was severely limited, leading to potential occupational exposures and healthcare personnel infection.Shortages of PPE put nurses at risk of exposure and infection. Multiple studies have found that U.S. hospitals and healthcare agencies lack sufficient PPE and even stockpiles have not provided adequate or correct supplies to give healthcare personnel necessary PPE during past events (Lautenbach, Saint, Henderson, & Harris, 2010; Rebmann & Wagner, 2009). During the 2014 Ebola outbreak, PPE availability was severely limited, leading to potential occupational exposures and healthcare personnel infection (Kilmarx et al., 2014). When respirators are limited, remaining supplies can be worn for extended periods of time or re-used between patients (Rebmann et al., 2013). However, extending the use or re-using respirators puts nurses at risk of exposure due to auto-inoculation when removing contaminated equipment or from reduced compliance during long-term wear (Rebmann et al., 2013; Seale, Corbett, Dwyer, & MacIntyre, 2009).
Staffing Shortages
Staff shortages can limit the availability of infection preventionists... Staffing shortages during infectious disease disasters may leave nurses at risk of occupational exposure due to exhaustion and insufficient infection prevention measures (Kilmarx et al., 2014). Staff shortages can limit the availability of infection preventionists to assist with training and PPE compliance checks, which can result in exposures and illness (Pathmanathan et al., 2014). During the Ebola outbreak in Sierra Leone, staffing shortages were common and believed to be associated with the high rate of infection among healthcare personnel (Kilmarx et al., 2014).
Changing Recommendations
...recommended control measures may change mid-event. Another challenge to following infection prevention practices during an infectious disease disaster is that recommended control measures may change mid-event. This is especially true during outbreaks of a new or emerging infectious disease, when limited information about the causative agent is available. As clinical and epidemiological data is obtained on the new or emerging disease, PPE or isolation recommendations may be altered (Rebmann & Wagner, 2009).
Changing infection prevention recommendations occurred during the 2003 SARS outbreak (Rebmann, 2014), the 2009 H1N1 pandemic (Rebmann & Wagner, 2009), and the 2014 Ebola outbreak (CDC, 2014b), and is likely to occur in future events. It is common for the CDC to take a conservative approach to recommended PPE and isolation when a new or emerging infectious disease occurs and there are limited data about the disease transmission route (Rebmann, 2014). For example, the CDC recommends use of airborne isolation and N95 respirators when providing care to patients infected with SARS Co-V or MERS Co-V, though transmission likely occurs primarily through respiratory droplets rather than airborne droplet nuclei. The CDC also updated PPE recommendations for healthcare personnel providing care to patients during the 2014 Ebola outbreak (CDC, 2015). Nurses should expect changing recommendations during outbreaks of new or emerging infectious diseases, in an ongoing effort to limit or prevent occupational exposures.
... the foundational tenets of infection prevention practices are the basis of routine care and the starting point for care during emerging infectious diseases. In sum, measures to prevent infection are challenging during stable times, and more challenging during critical outbreaks. However, the foundational tenets of infection prevention practices are the basis of routine care and the starting point for care during emerging infectious diseases. The lack of knowledge and compliance in the area of infectious disease prevention practices is of concern. The following section briefly summarizes the role of microorganisms in disease transmission and discusses infection prevention competencies and training appropriate for nurses in everyday practice and during times of emerging infectious diseases in the United States and/or globally.
Role of Microorganisms in Disease Transmission
Nurses must understand the epidemiological triangle, as this informs the basis for competent practice... An essential component of infection prevention is basic knowledge regarding the role microorganisms play in disease transmission. Nurses must understand that infection or colonization in a patient or healthcare worker enables disease transmission, because it means that an infectious agent is present. If an infectious agent interacts with a susceptible host (e.g., an unimmunized healthcare worker) within an environment that enables transmission, an infection can occur; this is known as the epidemiological triangle (CDC, 2011). This model emphasizes the critical need for nurses to have a working knowledge of the types of microorganisms (e.g., bacteria, virus) in transmission methods that cause disease so appropriate interventions can be implemented. Nurses must understand the epidemiological triangle (pictured in the figure below), as this informs the basis for competent practice, regardless of whether it is a commonly encountered infectious disease or an emerging pathogen.

Infection Prevention Competencies for Nurses
Professional competencies are a method to articulate knowledge and skills that individuals need to perform successfully in a given field. One of the earliest sets of nursing and infectious disease competencies focused on public health preparedness (Gebbie & Qureshi, 2002); they have been accepted as a cornerstone for safe practice in public health. Best practices related to infection prevention have been outlined in numerous CDC guidelines and related regulatory requirements and standards regarding care provided in healthcare settings.
Lack of a clear national document regarding basic infection prevention practices applicable for healthcare workers in all settings where care is delivered is a recognized gap. Guidelines provide information on what should occur, but do not include how nurses should apply the information. Recommendations regarding infection prevention competencies for hospital-based healthcare workers in the United States was first proposed in 2008 (Carrico, Rebmann, English, Mackey, & Cronin, 2008) and for healthcare workers in Canada in 2006 (Henderson, 2006). A summary of the proposed competencies is found in the Table. Lack of a clear national document regarding basic infection prevention practices applicable for healthcare workers in all settings where care is delivered is a recognized gap. This gap has been discussed at the national level, and the CDC (2014c) is currently developing guidelines to provide a set of broadly applicable practices that lead to widespread acceptance and implementation.

Nurse Education Related to Infection Prevention
Existing infection prevention competencies [include] the need for nurses to be aware of altered standards of care in situations that involve limited resources. Education for nurses related to infection prevention is critical to ensure adequate knowledge and safe practice (Casalino et al., 2015). Existing infection prevention competencies, such as those in the Table above, should be used as the basis for this training, including the need for nurses to be aware of altered standards of care in situations that involve limited resources (Carrico et al., 2008). Applying this competency to local or global emerging infectious diseases means that nurses must be aware of the proper way to extend the use or re-use respiratory protection during biological disasters that result in an influx of contagious patients and depletion of PPE (Rebmann et al., 2013). It also requires providing nurses with event- or disease-specific education if the CDC recommends PPE beyond what is used during routine practice. An example of this is the use of full PPE (i.e., boots, impermeable apron) for patients infected with Ebola (Casalino et al., 2015).
One critical aspect of infection prevention training is that nurses demonstrate their competence (Carrico et al., 2008). This demonstration must extend beyond written or verbal mastery of the information and include physical demonstration of proper infection prevention practices. Researchers have found that nurses often have high knowledge of correct infection prevention protocols, yet their behaviors demonstrate low compliance (Jessee & Mion, 2013).
...including an observer who speaks aloud the PPE donning and doffing process steps as part of the training process results in significantly better performance. This knowledge-compliance gap is one reason why the CDC recommends incorporating trained observers into the donning and doffing process for healthcare personnel providing care for Ebola patients. Observers can identify and immediately stop errors that could lead to auto-inoculation (Cummings et al., 2016). In addition, researchers have found that including an observer who speaks aloud the PPE donning and doffing process steps as part of the training process results in significantly better performance (Casalino et al., 2015). Although incorporating observers into the PPE donning and doffing process may not be feasible to provide routine nursing care, an investment in this quality check may be warranted during outbreaks of a new or emerging infectious disease to prevent occupational exposure or illness.
Conclusion
Proper infection prevention is essential for routine nursing practice, during disasters, and when providing care to individuals infected with a new or emerging infectious disease. Proper infection prevention is essential for routine nursing practice, during disasters, and when providing care to individuals infected with a new or emerging infectious disease. Lack of compliance with infection prevention can put nurses at risk for occupational exposure or contribute to healthcare-associated disease transmission. Many nurses are not consistently compliant with infection prevention procedures, including lapses in personal protective equipment usage.
Better education about infection prevention that involves demonstration of proper performance is essential to ensure adequate knowledge and safe practice. Existing infection prevention competencies should be the basis for nurse training. Nurses should receive education about routine procedures as the basis for all care, and disease- or event-specific recommendations that includes information about altered standards of care in situations that involve limited resources.
