“…In addition, we explored the potential reservoirs of S. capitis NRCS-A inside one NICU. In previous studies, incubators [11], ventilation system, balloons used for manual ventilation [12], diapers scale [13], stethoscopes and electronic devices [14] and mattresses [15] have been incriminated as environmental reservoirs of other pathogens, e.g. Staphylococcus aureus, Bacillus cereus , Enterococcus faecalis, Klebsiella pneumoniae .…”

Background The methicillin-resistant clone Staphylococcus capitis NRCS-A, involved in sepsis in neonatal intensive care units (NICUs) worldwide, is able to persist and spread in NICUs, suggesting the presence of reservoirs inside each setting. The purpose of the present study was to identify these reservoirs and to investigate the cycle of transmission of NRCS-A in one NICU. Methods In a single institution study, NRCS-A was sought in 106 consecutive vaginal samples of pregnant women to identify a potential source of NRCS-A importation into the NICU. Additionally NICU caregivers and environmental including incubators were tested to identify putative secondary reservoirs. Finally, the efficacy of disinfection procedure in the elimination of NRCS-A from incubators was evaluated. Results No S. capitis was isolated from vaginal samples of pregnant women. Three of the 21 tested caregivers (14%) carried S. capitis on their hands, but none remain positive after a five-day wash-out period outside NICU. Moreover, the clone NRCS-A persisted during six consecutive weeks in the NICU environment, but none of the sampled sites was constantly contaminated. Finally in our before/after disinfection study, all of 16 incubators were colonized before disinfection and 10 (62%) incubators remained colonized with NRCS-A after the disinfection procedure. Conclusions The partial ineffectiveness of incubators’ disinfection procedures is responsible for persistence of NRCS-A inside a NICU, and the passive hand contamination of caregivers could be involved in the inter-patient transmission of S. capitis.

“…The contamination of frequently touched hospital surfaces with drug-resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) (Knelson et al, 2014;Lin et al, 2016), vancomycin-resistant Enterococcus (VRE) (Knelson et al, 2014;Bonton et al, 1996), carbapenem-resistant Enterobacteriaceae (CRE) (Lerner et al, 2013;Weber et al, 2015), Acinetobacter species (Weber et al, 2010), and Clostridium difficile (Weber et al, 2010;Sitzlar et al, 2013) has been well documented. It has been estimated that 30-40% of HAIs are caused by the contamination of healthcare worker hands; hands are contaminated either from contact with infected or colonized patients, or with their environment (Weber et al, 2010).…”

The healthcare setting is predisposed to harbor potential pathogens, which in turn can pose a great risk to patients. Routine cleaning of the patient environment is critical to reduce the risk of hospital-acquired infections. While many approaches to environmental cleaning exist, manual cleaning supplemented with ongoing assessment and feedback may be the most feasible for healthcare facilities with limited resources.

“…Compliance with hand hygiene, active surveillance, and contact isolation either singularly or in conjunction have been insufficient and controversial. One study showed the decrease in MRSA acquisition was primarily attributed to the barrier effects of gowns and gloves followed by improved hand hygiene and lower HCW-patient contact rates [38]. However, other research reported only before and after patient contact rose from 40% to 76% for hand hygiene compliance.…”

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.
