Respiratory syncytial virus nosocomial outbreak in neonatal intensive care: A review of the incidence, management, and outcomes. Am J Infect Control 2022; 50:801-808. [PMID: 34736992 DOI: 10.1016/j.ajic.2021.10.027] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 10/20/2021] [Accepted: 10/21/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND The main objective was to determine the incidence, management, and outcomes of respiratory syncytial virus nosocomial infection (RSVNI) outbreaks in neonatal intensive care units. METHODS A comprehensive search of RSVNI in 9 databases was conducted from January 1, 2000 to May 1, 2021, of which the Cochrane Library comprised the Cochrane central register of controlled trials and the Cochrane database of systematic reviews. Two hundred and twenty-eight articles were retrieved and 17 were retained. A descriptive analysis was performed, and frequencies are reported as mean, median, and range where pertinent. RESULTS One hundred and seventeen infants were analyzed and comprised preterms (88.1%) and those with pre-existing co-morbidities. The estimated proportional incidence of RSVNI was 23.8% (177/744) infants. Outbreaks were principally managed by conventional protective measures, neonatal intensive care unit closure, and visitor restriction. Palivizumab was used to control RSVNI in 10 studies. RSVNI-related mortality was 8.5% (15/177) and 8.0% (7/87) among infants where infection control was solely employed. CONCLUSION RSVNI is associated with significant morbidity and mortality. The use of palivizumab should be a multidisciplinary decision, based on rapidly spreading infection. Prospective studies are essential to determine the cost-benefit of palivizumab versus standard prevention control for an RSVNI outbreak.

Viral Respiratory Infection, a Risk in Pediatric Cardiac Surgery: A Propensity-Matched Analysis. Pediatr Crit Care Med 2020; 21:e431-e440.

Abstract
OBJECTIVES 1) To describe the postoperative course and outcomes of cardiac surgery in children with perioperative viral respiratory infection, 2) to evaluate optimal surgical timing for preoperative viral respiratory infection patients, and 3) to define risk stratification. DESIGN Retrospective study of children undergoing cardiac surgery. Children were tested using a multiplex polymerase chain reaction (respiratory virus polymerase chain reaction) panel capturing seven respiratory viruses. Respiratory virus polymerase chain reaction testing was routinely performed in patients under 2 years old. Those with negative results yet highly suspected of viral respiratory infection after surgeries would be tested again. SETTING A pediatric cardiac surgical ICU of pediatric cardiac surgery department at Fuwai Hospital. PATIENTS Children admitted between January 1, 2014, and December 31, 2016, to perform respiratory virus polymerase chain reaction testing and cardiac surgery were included. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 2,831 patients had respiratory virus polymerase chain reaction testing, and viruses were detected in 91 patients (3.2%), including 35 preoperative and 56 postoperative. Of the 35 preoperative viral respiratory infection patients, there were 29 viral respiratory infection-resolved (patients for whom surgery was postponed until resolution of viral respiratory infection symptoms and negative respiratory virus polymerase chain reaction) and six viral respiratory infection-unresolved (who underwent cardiac surgery before resolution of symptoms and clearance of carriage) patients. Furthermore, there were seven deaths, including one in the preoperative viral respiratory infection-unresolved group and six in the postoperative viral respiratory infection group. A propensity score matching was performed to correct the selection bias and identify the comparable patient groups. Compared to their matched nonviral respiratory infection patients, viral respiratory infection-resolved patients had similar duration of mechanical ventilation and length of stay, while viral respiratory infection-unresolved patients had longer durations of postoperative mechanical ventilation (p = 0.033), PICU (p = 0.028) and hospital length of stay (p = 0.010), and postoperative viral respiratory infection patients had significantly greater duration of postoperative recovery (p < 0.001) and higher mortality (p < 0.001). Earlier diagnosis of postoperative viral respiratory infection was associated with longer mechanical ventilation duration (r = 0.422; p < 0.001). Palliative cardiac surgery was the only variable significantly associated with mortality in multivariate analysis (odds ratio, 12.0; 95% CI, 1.6-87.5; p = 0.014). CONCLUSIONS The preoperative-unresolved and postoperative viral respiratory infection were associated with prolonged postoperative recovery, increased severity, and mortality in children with cardiac surgeries. Our results suggested the optimal surgical timing may be after the resolution of viral respiratory infection symptoms and carriage unless the perceived benefits of early surgery outweigh the risk of death, prolonged ventilation, and PICU length of stay. Palliative surgeries were associated with increasing mortality.

Abstract
Children with medical complexity (CMC) are vulnerable to respiratory illness hospitalization (RIH) and respiratory syncytial virus (RSV)-related hospitalization (RSVH) due to multisystem disorders and compromised airways. It is unknown whether RSV prophylaxis is effective, or if RSVH is associated with significant morbidities in CMC. The study objectives were to (1) determine the incidence of RSV-related infection in prophylaxed CMC during the first 3 years of life and (2) assess the burden of illness following RSVH. A single tertiary center, retrospective study, was conducted of CMC who received palivizumab during the 2012-2016 RSV seasons. Fifty-four subjects were enrolled; most received one (38.9%, n = 21) or two (57.4%, n = 31) seasons of prophylaxis (mean = 4.2 [SD = 1.24], palivizumab doses per season). The cohort comprised children with multiple medical conditions (n = 22, 40.8%), tracheostomy (n = 18, 33.3%), and invasive (n = 10, 18.5%) or non-invasive (n = 4, 7.4%) ventilation. Of the CMC, 24 were hospitalized 47 times for a viral-related respiratory illness. RSV incidence in the first 3 years of life was 7.4%. Viral-related RIH and RSVH rates were 44.4% (n = 24/54) and 1.9% (n = 1/54), respectively. Of the four RSV-positive children, one was ventilated for 9 days, two acquired nosocomial RSV that was managed on the ward, and one was discharged home under close complex care supervision. All four RSV-positive cases required additional oxygen during their illness. CMC experience a high viral-related RIH rate and palivizumab likely minimizes RSV-related events and associated morbidities. The efficacy of palivizumab in CMC, especially in those ≤ 3 years, should be prospectively evaluated.

Abstract
BACKGROUND Palivizumab is the standard immunoprophylaxis against serious disease due to respiratory syncytial virus infection. Current evidence-based prophylaxis guidelines may not address certain children with CHD within specific high-risk groups or clinical/management settings. METHODS An international steering committee of clinicians with expertise in paediatric heart disease identified key questions concerning palivizumab administration; in collaboration with an additional international expert faculty, evidence-based recommendations were formulated using a quasi-Delphi consensus methodology. RESULTS Palivizumab prophylaxis was recommended for children with the following conditions: <2 years with unoperated haemodynamically significant CHD, who are cyanotic, who have pulmonary hypertension, or symptomatic airway abnormalities; <1 year with cardiomyopathies requiring treatment; in the 1st year of life with surgically operated CHD with haemodynamically significant residual problems or aged 1-2 years up to 6 months postoperatively; and on heart transplant waiting lists or in their 1st year after heart transplant. Unanimous consensus was not reached for use of immunoprophylaxis in children with asymptomatic CHD and other co-morbid factors such as arrhythmias, Down syndrome, or immunodeficiency, or during a nosocomial outbreak. Challenges to effective immunoprophylaxis included the following: multidisciplinary variations in identifying candidates with CHD and prophylaxis compliance; limited awareness of severe disease risks/burden; and limited knowledge of respiratory syncytial virus seasonal patterns in subtropical/tropical regions. CONCLUSION Evidence-based immunoprophylaxis recommendations were formulated for subgroups of children with CHD, but more data are needed to guide use in tropical/subtropical countries and in children with certain co-morbidities.

Abstract
INTRODUCTION REGAL (RSV Evidence-a Geographical Archive of the Literature) has provided a comprehensive review of the published evidence in the field of respiratory syncytial virus (RSV) in Western countries over the last 20 years. This review covers the risk and burden of RSV infection in children with underlying medical conditions or chronic diseases (excluding prematurity and congenital heart disease). METHODS A systematic review of publications between January 1, 1995 and December 31, 2015 across PubMed, Embase, The Cochrane Library, and Clinicaltrials.gov was supplemented by papers identified by the authors through March 2017. Studies reporting data for hospital visits/admissions for RSV infection as well as studies reporting RSV-associated morbidity and mortality were included. Study quality and strength of evidence (SOE) were graded. RESULTS A total of 2703 studies were identified and 58 were included. Down syndrome, irrespective of prematurity and congenital heart disease (moderate SOE), immunocompromised children (low SOE), cystic fibrosis (low SOE), and neurologic conditions (low SOE) were associated with a significantly increased risk of RSV hospitalization. A number of other congenital malformations and chronic conditions were also associated with severe RSV disease (low SOE). In general, pre-existing disease was also a predisposing factor for RSV-related mortality (low SOE). CONCLUSION Severe RSV infection in infants and young children with underlying medical conditions or chronic diseases poses a significant health burden. Further studies are needed to fully quantify the epidemiology, burden and outcomes in these populations, in particular RSV-attributable mortality.

Abstract
Introduction The REGAL (RSV Evidence—a Geographical Archive of the Literature) series provide a comprehensive review of the published evidence in the field of respiratory syncytial virus (RSV) in Western countries over the last 20 years. This fourth publication covers the risk and burden of RSV infection in infants with congenital heart disease (CHD). Methods A systematic review was undertaken for articles published between January 1, 1995 and December 31, 2015 across PubMed, Embase, The Cochrane Library, and Clinicaltrials.gov. Studies reporting data for hospital visits/admissions for RSV infection among children with CHD as well as studies reporting RSV-associated morbidity, mortality, and healthcare costs were included. The focus was on children not receiving RSV prophylaxis. Study quality and strength of evidence (SOE) were graded using recognized criteria. Results A total of 1325 studies were identified of which 38 were included. CHD, in particular hemodynamically significant CHD, is an independent predictor for RSV hospitalization (RSVH) (high SOE). RSVH rates were generally high in young children (<4 years) with CHD (various classifications), varying between 14 and 357/1000 (high SOE). Children (<6 years) with RSV infection spent 4.4–14 days in hospital, with up to 53% requiring intensive care (high SOE). Infants (<2 years) with CHD had a more severe course of RSVH than those without CHD (high SOE). Case fatality rates of up to 3% were associated with RSV infection in children with CHD (high SOE). RSV infection in the perioperative period of corrective surgery and nosocomial RSV infection in intensive care units also represent important causes of morbidity (moderate SOE). Conclusion CHD poses a significant risk for RSVH and subsequent morbidity and mortality. RSV infection often complicates corrective heart surgery. To reduce the burden and improve outcomes, further research and specific studies are needed to determine the longer-term effects of severe RSV infection in young children with CHD.

Abstract
BACKGROUND The burden of healthcare-associated infection worldwide is considerable, and there is a need to improve surveillance and infection control practices such as hand hygiene. OBJECTIVES The aims of this study were to explore direct care providers' knowledge about infection prevention and hand hygiene, their attitudes regarding their own and others' hand hygiene practices, and their ideas and advice for improving infection prevention efforts. METHODS This exploratory study included interviews with direct care providers in three pediatric long-term care facilities. Two trained nurse interviewers conducted semistructured interviews using an interview guide with open-ended questions. Two other nurse researchers independently transcribed the audio recordings and conducted a thematic analysis using a strategy adapted from the systematic text condensation approach. RESULTS From 31 interviews, four major thematic categories with subthemes emerged from the analysis: (a) hand hygiene products; (b) knowledge, awareness, perceptions, and beliefs; (c) barriers to infection prevention practices; and (d) suggested improvements. There was confusion regarding hand hygiene recommendations, use of soap or sanitizer, and isolation precaution policies. There was a robust "us" and "them" mentality between professionals. DISCUSSION One essential driver of staff behavior change is having expectations that are meaningful to staff, and many staff members stated that they wanted more in-person staff meetings with education and hands-on, practical advice. Workflow patterns and/or the physical environment need to be carefully evaluated to identify systems and methods to minimize cross-contamination. Further studies need to evaluate if personal sized containers of hand sanitizer (e.g., for the pocket, attached to a belt or lanyard) would facilitate improvement of hand hygiene in these facilities.

Abstract
INTRODUCTION Introduction: Children in extended care facilities (ECFs) are at risk of healthcare-associated infections, but little hand hygiene (HH) research has been conducted in this unique setting. METHODS Eight children across four pediatric ECFs were observed for a cumulative 128 hours, and all care giver HH opportunities were characterized by the World Health Organization's '5 Moments for HH'. Data were analyzed using Pearson's χ2 test. RESULTS Observers documented 865 HH opportunities. Overall HH adherence was 43% and was significantly higher among clinical care givers than among non-clinical care givers (61% and 14%, respectively, (p < .01). CONCLUSIONS Hand hygiene adherence was low, suggesting multiple opportunities for transmission of infectious agents.

Abstract
Clinically obvious reasons why children with neurological impairment (NMI) may be more severely affected in case of a viral respiratory tract infection include reduced vital capacity due to muscular weakness or spastic scoliosis, disturbed clearance of respiratory excretions (weak coughing and dysphagia), inability to comply actively with physiotherapeutic interventions, recurrent micro-aspirations (gastroesophageal reflux disease, vomiting related to coughing), a history of frequent exposure to antibiotics and health care institutions, colonization with resistant pathogens, impaired immunologic defence mechanisms due to severe malnutrition and cachexia, and early clinical deterioration in case of high fever with metabolic acidosis and hypercapnia, and maybe associated seizures or febrile convulsions. Data from the literature suggests that in all children with NMI, who have to be hospitalized with severe clinical deterioration due to an airway infection, at least one specimen of nasopharyngeal secretions should be sent as soon as possible to a virologic laboratory to detect viral pathogens. Children with severe NMI and those mechanically ventilated for other reasons being hospitalized during the RSV season must be strictly protected against nosocomial RSV infection by means of standard and droplet precautions. Finally, children with severe NMI and age below 24 months of life should receive passive immunization with palivizumab following international recommendations.

Abstract
OBJECTIVE Although some studies indicate a low risk of serious bacterial infection in infants with respiratory syncytial virus (RSV), these studies focused on patients who did not progress to respiratory failure. We hypothesized the composite diagnosis of concomitant bacterial pneumonia (CBP) is common in lower risk infants with RSV who present in respiratory failure. The aim of the study was to investigate the incidence of CBP in low-risk infants mechanically ventilated for RSV respiratory failure and to compare the results with other studies searched for in MEDLINE. DESIGN Prospective, descriptive study, and literature review. Two MEDLINE searches were done using the terms 1) respiratory syncytial virus (RSV) and pneumonia, and 2) RSV, pneumonia, and antibiotics. SETTING Tertiary pediatric intensive care unit (PICU) in the Northeast United States. PATIENTS We prospectively enrolled 23 infants admitted to our PICU with RSV infection and respiratory failure over a 27-month period. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS All infants were intubated on arrival or soon thereafter; 22 had diagnostic tracheal aspiration performed, and 20 had blood cultures obtained shortly after admission. All had white blood cell count, temperature measured, and chest radiograph. Only one had antibiotics before culture. The length of mechanical ventilation, PICU course, and hospital stay were recorded.The primary outcome variable was the composite diagnosis of CBP as determined by the following criteria: 1) isolation of pathogenic bacteria from a tracheal aspirate, 2) blood culture, 3) chest radiograph, 4) temperature abnormality, and 5) peripheral white blood cell count. In our study, 7 infants met four criteria (probable pneumonia); 6 met three criteria (possible pneumonia); and 10 infants met less than three criteria. By tracheal aspirate criteria alone, 9 of 23 (39%) had probable pneumonia and 9 of 23 had possible pneumonia by previously published criteria. The mean length of mechanical ventilation for 7 infants who met four criteria was 10 +/- 2.7 (sem) days; for 6 infants who met three criteria, 10.5 +/- 2.1 days; and for infants who met less than three criteria 7.4 +/- 0.9 days. The mean PICU stay was 14.3 +/- 3.6 days for infants who met four criteria; 14.3 +/- 3.0 days for infants who met three criteria; and 9.9 +/- 1.4 days for infants who met less than three criteria. The mean hospital stay was 16.3 +/- 3.4 for infants who met four criteria; 18.7 +/- 2.8 days for infants who met three criteria; and 24.8 +/- 9.6 days for infants who met less than three criteria. These differences were not statistically significant. A MEDLINE search was performed using the terms 1) RSV and pneumonia, and 2) RSV, pneumonia, and antibiotics. CONCLUSIONS While the small size of this study does not permit definitive conclusions, these data, in combination with other data from the literature, suggest that composite evidence of bacterial pneumonia in otherwise low-risk infants with RSV presenting with respiratory failure is 20% or higher and the use of empirical antibiotics for 24 to 48 hrs pending culture results may be justified and could be used until CBP is excluded.

Abstract
Respiratory syncytial virus (RSV) is a pathogen whose existence has been known for decades, causing mild-to-severe upper and lower respiratory tract infections that bear the risk of subsequent asthma and can even lead to a fatal outcome. RSV infects all groups of patients and is a major cause of hospitalization in children and in the elderly. This review briefly summarizes the current status of RSV drug development and clinical trials for drugs available for the treatment of RSV infections.
