Healthcare worker perceptions surrounding Staphylococcus aureus transmission and prevention practices in the neonatal intensive care unit. Infect Control Hosp Epidemiol 2023; 44:1953-1958. [PMID: 37272454 PMCID: PMC10755153 DOI: 10.1017/ice.2023.86] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 03/28/2023] [Accepted: 04/04/2023] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To understand healthcare worker (HCW) perceptions surrounding Staphylococcus aureus transmission and prevention in the neonatal intensive care unit (NICU). DESIGN Qualitative case study with focus groups. SETTING A level IV, 150-bed NICU at a Midwestern academic medical center that conducts active surveillance and decolonization of S. aureus-positive patients. PARTICIPANTS NICU HCWs, including bedside nurses, nurse managers, therapy services personnel, pediatric nurse practitioners, clinical fellows, and attending neonatologists. METHODS Semistructured focus group interviews, assembled by occupation, were conducted by 2 study team members. Interviews were video recorded and transcribed. Deductive coding and thematic analyses were performed using NVivo software. RESULTS In total, 38 HCWs participated in 10 focus groups (1-12 participants each), lasting 40-90 minutes. Four main themes emerged: (1) Methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) are inconsistently described as high risk. (2) Infection prevention interventions are burdensome. (3) Multiple sources of transmission are recognized. (4) opportunities exist to advance infection prevention. HCWs perceived MSSA to be less clinically relevant than MRSA. Participants expressed a desire to see published data supporting infection prevention interventions, including contact precautions, environmental cleaning, and patient decolonization. These practices were identified to be considerable burdens. HCWs perceived families to be the main source of S. aureus in the NICU, and they suggested opportunities for families to play a larger role in infection prevention. CONCLUSIONS These data highlight opportunities for HCW and parental education, research, and reevaluating interventions aimed at improving infection prevention efforts to reduce the burden of S. aureus in NICU settings.

Abstract
BACKGROUND Central-line-associated bloodstream infection (CLABSI) contributes to significant morbidity and mortality in the neonatal intensive care unit (NICU). Disinfection of skin is part of bundled cares aimed at prevention of CLABSI. While considered an essential component of insertion and maintenance bundles, the optimal solution to disinfect neonatal skin remains controversial. PURPOSE The purpose of this project was to survey neonatal nurse practitioners and nursing leaders across NICUs regarding the current use of chlorhexidine gluconate (CHG) in term and preterm infants. METHODS This descriptive study involved the collection of survey data to determine NICU practices related to the use of CHG in their infant population. The sample was composed of nursing directors of NICUs and neonatal nurse practitioners who completed an electronic survey via a provided link. FINDINGS/RESULTS Chlorhexidine was reported to be used in 53 (82.81%) of the NICUs and was the primary agent used to prepare the skin for central vascular catheter insertion (53.23%) followed by povidone-iodine (45.16%), and 70% isopropyl alcohol (1.61%). Gestational age or birth weight restrictions for CHG use were reported in 43 (82.69%) NICUs. Trends in the data demonstrated nursing's role in using CHG in the NICU. Adverse events reported from CHG included burns, redness, dermatitis, and other irritations. Concerns included risk of absorption, burns, skin irritation, lack of evidence, and overall safety. IMPLICATIONS FOR PRACTICE Systematic monitoring by nurse leaders is needed to identify evidence related to skin disinfection and CHG in neonates. Targeted education for nursing staff related to directed to developmental maturation of the skin, safe use of CHG, review of best evidence, rationale for usage of CHG, and potential iatrogenic effects is recommended. IMPLICATIONS FOR RESEARCH Research is needed to evaluate the impact of educational offerings and surveillance for adverse events on CLABSI rates.

Abstract
BACKGROUND Healthcare-associated infections in neonatal and paediatric populations are associated with poorer outcomes and healthcare costs, and surveillance is a necessary component of prevention programmes. AIM To evaluate burden of illness, aetiology, and time-trends for central and peripheral line-associated bloodstream infection (CLABSI and PLABSI) in Australian neonatal and paediatric intensive care units (ICUs) between July 1st, 2008 and December 31st, 2016. METHODS Using National Healthcare Safety Network methods, surveillance in neonatal and paediatric units was performed by hospitals participating in the Victorian Healthcare Associated Infection Surveillance System. Mixed effects Poisson regression was used to model infections over time. FINDINGS Overall, 82 paediatric CLABSI events were reported during 37,125 CVC-days (2.21 per 1000 CVC-days), 203 neonatal CLABSI events were reported during 92,169 CVC-days (2.20 per 1000 CVC-days), and 95 neonatal PLABSI events were reported during 142,240 peripheral line-days (0.67 per 1000 peripheral line-days). Over time, a significant decrease in quarterly risk for neonatal CLABSI events was observed (risk ratio (RR): 0.98; 95% confidence interval: 0.97-0.99; P = 0.023) and this reduction was significant for the 751-1000 g birth weight cohort (RR: 0.97; P = 0.015). Most frequently, coagulase-negative Staphylococcus spp. (24.2%) and Staphylococcus aureus (16.1%) were responsible for CLABSI events. A significant reduction in Gram-negative neonatal infections was observed (annual RR: 0.85; P < 0.001). CONCLUSION CLABSI rates in neonatal and paediatric ICUs in our region are low, and neonatal infections have significantly diminished over time. Evaluation of infection prevention programmes is required to determine whether specific strategies can be implemented to further reduce infection risk.

Abstract
CONTEXT Methicillin-resistant Staphylococcus aureus (MRSA) causes a significant burden of illness in neonatal intensive care units (NICUs) worldwide. Identifying infants colonized with MRSA has become an important infection control strategy to interrupt nosocomial transmission. OBJECTIVE Assess risk factors for MRSA colonization in NICUs via a systematic review and meta-analysis. DATA SOURCES MEDLINE, Embase, Web of Science, and The Cochrane Library databases were searched from inception through September 2015. STUDY SELECTION Studies reporting risk factors for MRSA colonization using noncolonized controls in subspecialty level III or IV NICUs were included. DATA EXTRACTION Two authors independently extracted data on MRSA colonization risk factors, study design, and MRSA screening methodology. RESULTS Eleven articles were included in the systematic review, with 10 articles analyzed via meta-analysis. MRSA colonization was associated with gestational age <32 weeks (odds ratio [OR], 2.67; 95% confidence interval [CI], 1.35-5.27; P = .01) and birth weight <1,500 g (OR, 2.63; 95% CI, 1.25-5.55; P = .01). Infant sex (P = .21), race (P = .06), inborn status (P = .09), and delivery type (P = .24) were not significantly associated with colonization. CONCLUSIONS Very preterm and very-low birth weight infants were identified as having an increased risk for MRSA colonization on meta-analysis. Multifaceted infection prevention strategies should target these high-risk infants to reduce MRSA colonization rates in NICUs.

Abstract
Nosocomial or hospital acquired infections threaten the survival and neurodevelopmental outcomes of infants admitted to the neonatal intensive care unit, and increase cost of care. Premature infants are particularly vulnerable since they often undergo invasive procedures and are dependent on central catheters to deliver nutrition and on ventilators for respiratory support. Prevention of nosocomial infection is a critical patient safety imperative, and invariably requires a multidisciplinary approach. There are no short cuts. Hand hygiene before and after patient contact is the most important measure, and yet, compliance with this simple measure can be unsatisfactory. Alcohol based hand sanitizer is effective against many microorganisms and is efficient, compared to plain or antiseptic containing soaps. The use of maternal breast milk is another inexpensive and simple measure to reduce infection rates. Efforts to replicate the anti-infectious properties of maternal breast milk by the use of probiotics, prebiotics, and synbiotics have met with variable success, and there are ongoing trials of lactoferrin, an iron binding whey protein present in large quantities in colostrum. Attempts to boost the immunoglobulin levels of preterm infants with exogenous immunoglobulins have not been shown to reduce nosocomial infections significantly. Over the last decade, improvements in the incidence of catheter-related infections have been achieved, with meticulous attention to every detail from insertion to maintenance, with some centers reporting zero rates for such infections. Other nosocomial infections like ventilator acquired pneumonia and staphylococcus aureus infection remain problematic, and outbreaks with multidrug resistant organisms continue to have disastrous consequences. Management of infections is based on the profile of microorganisms in the neonatal unit and community and targeted therapy is required to control the disease without leading to the development of more resistant strains.

Abstract
Despite infection prevention efforts, neonatal intensive care unit (NICU) patients remain at risk of Methicillin-resistant Staphylococcus aureus (MRSA) infection. Modes of transmission for healthcare-associated (HA) and community-associated (CA) MRSA remain poorly understood and may vary by genotype, hindering the development of effective prevention and control strategies. From 2008–2010, all patients admitted to a level III NICU were screened for MRSA colonization, and all available isolates were spa-typed. Spa-type t008, the most prevalent CA- genotype in the United States, spa-type t045, a HA- related genotype, and a convenience sample of strains isolated from 2003–2011, underwent whole-genome sequencing and phylodynamic analysis. Patient risk factors were compared between colonized and noncolonized infants, and virulence and resistance genes compared between spa-type t008 and non-t008 strains. Epidemiological and genomic data were used to estimate MRSA importations and acquisitions through transmission reconstruction. MRSA colonization was identified in 9.1% (177/1940) of hospitalized infants and associated with low gestational age and birth weight. Among colonized infants, low gestational age was more common among those colonized with t008 strains. Our data suggest that approximately 70% of colonizations were the result of transmission events within the NICU, with the remainder likely to reflect importations of “outside” strains. While risk of transmission within the NICU was not affected by spa-type, patterns of acquisition and importation differed between t008 and t045 strains. Phylodynamic analysis showed the effective population size of spa-type t008 has been exponentially increasing in both community and hospital, with spa-type t008 strains possessed virulence genes not found among t045 strains; t045 strains, in contrast, appeared to be of more recent origin, with a possible hospital source. Our data highlight the importance of both intra-NICU transmission and recurrent introductions in maintenance of MRSA colonization within the NICU environment, as well as spa-type-specific differences in epidemiology.

Abstract
BACKGROUND Neonatal sepsis causes 1.4 million (36%) neonatal deaths annually. Staphylococcus aureus (SA), a common skin pathogen, remains the second leading cause of late-onset sepsis in the neonatal intensive care unit (NICU). Methicillin-resistant Staphylococcus aureus (MRSA), a resistant strain of SA, has created a significant global communicable health risk, especially in the NICU. PURPOSE To examine evidence related to NICU infection control practices surrounding MRSA surveillance, identification, and isolation in response to the clinical question, "What strategies should be universally implemented in the NICU to identify and prevent the spread of MRSA?" METHODS/SEARCH STRATEGY Databases were examined for articles on the topical area of MRSA in the neonate. Key terms were used to streamline the search, resulting in 20 primary works and 3 guideline/consensus statements considered imperative in response to the clinical questions. FINDINGS/RESULTS Hand hygiene remains the cornerstone to sound infection control practice. Colonization often leads to systemic infection, with smaller neonates at greatest risk. Hospital infection control compliance has improved outcomes. MRSA surveillance has reduced horizontal spread. No universal, specific recommendations exist to guide surveillance and management of MRSA in the NICU. IMPLICATIONS FOR PRACTICE Standardized guidelines with procedures for hand hygiene, patient surveillance and isolation, and patient cohorting with recommended staffing patterns should guide practice in the NICU. Both MRSA culture and polymerase chain reaction effectively identify positive patients. Decolonization practices are not yet clear. IMPLICATIONS FOR RESEARCH Evaluation of standard isolation practices versus outbreak response and approaches to neonatal decolonization should be evaluated for efficacy, safety, and resistance.

Abstract
Central line-associated bloodstream infections (CLABSIs) are an important cause of increased morbidity, mortality, and costs in neonatal intensive care unit (NICU) patients. In recent years, central line bundles have been developed and implemented as a means to reduce infection rates in intensive care units. The objective of this review was to describe central line bundles that are utilized in the neonatal population and evaluate the current evidence on the effectiveness of bundles for prevention of CLABSIs in the NICU. This review shows that care bundles have been successfully used in NICUs (as part of both single-site quality improvement initiatives and large multisite collaboratives) to decrease CLABSI rates. The individual components that comprise the bundle between individual studies varied, but all studies showed a significant reduction in CLABSI rates. The pre- and postintervention design employed by these studies does not allow for conclusions to be drawn as to what specific bundle components are most effective in reducing rates. Further research is needed both to examine the effectiveness of specific components or combinations of components in the bundle and to examine factors that are associated with implementation and adherence to bundles.
