Mode Of Transmission

Objective.To investigate the potential reservoir and mode of transmission of pandrug-resistant (PDR)Acinetobacter baumanniiin a 7-day-old neonate who developed PDRA. baumanniibacteremia that was presumed to be the iceberg of a potential outbreak.Design.Outbreak investigation based on a program of prospective hospital-wide surveillance for nosocomial infection.Setting.A 24-bed neonatal intensive care unit in a 2,200-bed major teaching hospital in Taiwan that provides care for critically ill neonates born in this hospital and those transferred from other hospitals.Interventions.Samples from 33 healthcare workers' hands and 40 samples from the environment were cultured. Surveillance cultures of anal swab specimens and sputum samples were performed for neonates on admission to the neonatal intensive care unit and every 2 weeks until discharge. The PDRA. baumanniiisolates, defined as isolates resistant to all currently available systemic antimicrobials except polymyxin B, were analyzed by pulsed-field gel electrophoresis. Control measures consisted of implementing contact isolation, reinforcing hand hygiene adherence, cohorting of nurses, and environmental cleaning.Results.One culture of an environmental sample and no cultures of samples from healthcare workers' hands grew PDRA. baumannii. The positive culture result involved a sample obtained from a ventilation tube used by the index patient. During the following 2 months, active surveillance identified PDRA. baumanniiin 8 additional neonates, and isolates from 7 had the same electrokaryotype. Of the 9 neonates colonized or infected with PDRA. baumannii, 1 died from an unrelated condition. Reinforcement of infection control measures resulted in 100% adherence to proper hand hygiene protocol. The outbreak was stopped without compromising patient care.Conclusions.In the absence of environmental contamination, transient hand carriage by personnel who cared for neonates colonized or infected with PDRA. baumanniiwas suspected to be the mode of transmission. Vigilance, prompt intervention and strict adherence to hand hygiene protocol were the key factors that led to the successful control of this outbreak. Active surveillance appears to be an effective measure to identify potential transmitters and reservoirs of PDRA. baumannii.

Objective. To evaluate the efficacy of bundle intervention on healthcare-associated (HA) methicillin-resistant Staphylococcus Aureus (MRSA) infection in the neonatal intensive care unit (NICU). Methods. In this study, 11,277 infants having undergone treatment at the NICU in Xiamen, China, from January 2014 to February 2017 were recruited. We retrospectively reviewed patients’ demographic and clinical information. Patients from 2014 to 2015 were treated as the control group and those from 2016 to 2017 were classified as the experimental group. Bundle intervention measures were performed, including screening for MRSA, isolation precautions, training of hand hygiene, cleaning protocols, and decontamination of isolation ward. The HA-MRSA data and compliance of infection control measures between both groups were analyzed. Results. Through bundle interventions, the compliance with the isolation of MRSA raised from 55.88% to 92.86% and hand hygiene compliance increased from 90.07% to 93.23% (P < 0.05). The HA infection decreased from 1.87% to 1.71% (P > 0.05) and HA detection rate of MRSA declined from 2.63‰ to 1.00‰, respectively (P < 0.05). Conclusion. Multifaceted interventions can effectively prevent MRSA infection and transmission; this includes active surveillance, isolation precautions, increased hand hygiene compliance, environmental cleaning, and decontamination.

Abstract Objective Our goal for this study was to quantify healthcare provider compliance with hand hygiene protocols and develop a conceptual framework for increasing hand hygiene compliance in a low-resource neonatal intensive care unit. Materials and Methods We developed a 3-phase intervention that involved departmental discussion, audit, and follow-up action. A 4-month unobtrusive audit during night and day shifts was performed. The audit results were presented, and a conceptual framework of barriers to and solutions for increasing hand hygiene compliance was developed collectively. Results A total of 1308 hand hygiene opportunities were observed. Among 1227 planned patient contacts, hand-washing events (707 [58.6%]), hand rub events (442 [36%]), and missed hand hygiene (78 [6.4%]) events were observed. The missed hand hygiene rate was 20% during resuscitation. Missed hand hygiene opportunities occurred 3.2 times (95% confidence interval, 1.9–5.3 times) more often during resuscitation procedures than during planned contact and 6.14 times (95% confidence interval, 2.36–16.01 times) more often when providers moved between patients. Structural and process determinants of hand hygiene noncompliance were identified through a root-cause analysis in which all members of the neonatal intensive care unit team participated. The mean hand-washing duration was 40 seconds. In 83% of cases, drying hands after washing was neglected. Hand recontamination after hand-washing was seen in 77% of the cases. Washing up to elbow level was observed in 27% of hand-wash events. After departmental review of the study results, hand rubs were placed at each bassinet to address these missed opportunities. Conclusions Hand hygiene was suboptimal during resuscitation procedures and between patient contacts. We developed a conceptual framework for improving hand hygiene through a root-cause analysis.

AbstractObjective:To investigate a cluster of patients infected and colonized withSerratia marcescensin a neonatal intensive care unit (NICU).Methods:In June 2001, two neonates in the NICU had clinical infections withS. marcescensand one died. Infection control surveillance data for the NICU revealed that S.marcescenswas rarely isolated from clinical specimens. Surveillance and environmental cultures were performed and isolates were typed using pulsed-field gel electrophoresis. Staff and neonates were cohorted and a waterless, alcohol-based handwashing agent was introduced. A case-control study was performed.Results:From June 2 through August 20, 2001, 11 neonates withS. marcescensinfection and colonization were identified. The incidence ofS. marcescensinfections increased from 0.19 per 1,000 patient-days in 2000 to 0.52 per 1,000 patient-days in 2001 (P< .0001). In the first 3 weeks of the investigation, there were 2 sets of patients and sinks with indistinguishable strains; however, in subsequent weeks, all isolates were of unique strains, signifying no further transmission of the two initial predominant strains. Neonates withS. marcescenswere more likely to have a lower gestational age and birth weight. There was no association between cases and healthcare workers (HCWs).Conclusions:A cluster ofS. marcescenswas quickly terminated after the introduction of preventive measures including cohorting of infected and colonized neonates and HCWs, contact precautions, surveillance cultures, and a waterless, alcohol-based hand antiseptic. Chromosomal typing determined that strains with an indistinguishable pattern were no longer present in the unit after control measures were implemented.
