OBJECTIVEWe aimed to determine the frequency of qacA/B chlorhexidine tolerance genes and high-level mupirocin resistance among MRSA isolates before and after the introduction of a chlorhexidine (CHG) daily bathing intervention in a surgical intensive care unit (SICU).DESIGNRetrospective cohort study (2005–2012)SETTINGA large tertiary-care centerPATIENTSPatients admitted to SICU who had MRSA surveillance cultures of the anterior naresMETHODSA random sample of banked MRSA anterior nares isolates recovered during (2005) and after (2006–2012) implementation of a daily CHG bathing protocol was examined for qacA/B genes and high-level mupirocin resistance. Staphylococcal cassette chromosome mec (SCCmec) typing was also performed.RESULTSOf the 504 randomly selected isolates (63 per year), 36 (7.1%) were qacA/B positive (+) and 35 (6.9%) were mupirocin resistant. Of these, 184 (36.5%) isolates were SCCmec type IV. There was a significant trend for increasing qacA/B (P=.02; highest prevalence, 16.9% in 2009 and 2010) and SCCmec type IV (P<.001; highest prevalence, 52.4% in 2012) during the study period. qacA/B(+) MRSA isolates were more likely to be mupirocin resistant (9 of 36 [25%] qacA/B(+) vs 26 of 468 [5.6%] qacA/B(−); P=.003).CONCLUSIONSA long-term, daily CHG bathing protocol was associated with a change in the frequency of qacA/B genes in MRSA isolates recovered from the anterior nares over an 8-year period. This change in the frequency of qacA/B genes is most likely due to patients in those years being exposed in prior admissions. Future studies need to further evaluate the implications of universal CHG daily bathing on MRSA qacA/B genes among hospitalized patients.Infect Control Hosp Epidemiol 2016;37:590–597

Although enteral feeding in critically ill patients has been shown to be beneficial, reliable postpyloric placement of feeding tubes remains a challenge. The standard of care involves blind placement, frequently requiring multiple attempts, and radiographs. To evaluate the effect of electromagnetic-guided bedside placement in reducing time to establishment of feeding, lung placement, use of radiography, and cost, we initiated a prospective trial using electromagnetic-guided bedside placement and compared them to a retrospective cohort. Fifty-three consecutive placements of nasoenteral feeding tubes were made using electromagnetic-guidance on patients requiring enteral nutrition in a surgical intensive care unit at a tertiary care center. Sixty-three placement attempts in the preceding seven months served as controls. There were no significant differences between the two groups in terms of age, sex, weight, body mass index, hiatal or ventral hernias, or previous esophageal/gastric operations. The number of radiographs needed per patient, need for fluoroscopy, radiology charge per patient for the tube placement, and time from first attempt at placement to confirmation of postpyloric location were lower for the electromagnetic-guided group. Use of electromagnetic guidance allows reliable and cost-effective postpyloric enteral feeding tube placement compared with blind insertion.

Abstract Background We report a nosocomial outbreak caused by Burkholderia cepacia that occurred among six patients admitted in the medical and surgical intensive care unit between 04 March 2019 and 02 April 2019 in Istanbul, Turkey. Methods The outbreak investigation was launched on 11 March 2019 five days after the detection of B. cepacia in four different patients. We defined potential reservoirs and started environmental screening. We sampled the liquid solutions used in patient care activities. Pulse-field gel electrophoresis (PFGE) was performed to determine the genetic relatedness of environmental and patient samples. Results Burkholderia cepacia was isolated in tracheal aspiration cultures of six patients. Three out of six patients developed healthcare-associated pneumoniae due to B. cepacia. Environmental cultures in the ICUs revealed B. cepacia growth in 2% chlorhexidine-gluconate mouthwash solution that been used in the colonized patients as well as in samples obtained from the unused products. PFGE revealed the patient and a specific batch of chlorhexidine mouthwash solution samples had a 96% similarity. Conclusion Contamination of medical solutions used in critical patient care could cause outbreaks and should be detected early by infection control teams. Graphic abstract

Abstract Objectives This study was aimed to assess the benefits of early tracheostomy (ET) compared with late tracheostomy (LT) on postoperative outcomes in pediatric cardiac surgical patients. Design Present one is a prospective, observational study. Setting The study was conducted at a cardiac surgical intensive care unit (ICU) of a tertiary care hospital. Participants All pediatric patients below 10 years of age, who underwent tracheostomy after cardiac surgery from January2019 to december2019, were subdivided into two groups according to the timing of tracheostomy: “early” if done before 7 days or “late” if done after 7 days postcardiac surgery. Interventions ET versus LT was measured in the study. Results Out of all 1,084 pediatric patients who underwent cardiac surgery over the study period, 41 (3.7%) received tracheostomy. Sixteen (39%) patients underwent ET and 25 (61%) underwent LT. ET had advantages by having reduced risk associations with the following variables: preoperative hospital stay (p = 0.0016), sepsis (p = 0.03), high risk surgery (p = 0.04), postoperative sepsis (p = 0.001), C-reactive protein (p = 0.04), ventilator-associated pneumonia (VAP; p = 0.006), antibiotic escalation (p = 0.006), and antifungal therapy (p = 0.01) requirement. Furthermore, ET was associated with lesser duration of mechanical ventilation (p = 0.0027), length of ICU stay (LOICUS; p = 0.01), length of hospital stay (LOHS; p = 0.001), lesser days of feed interruption (p = 0.0017), and tracheostomy tube change (p = 0.02). ET group of children, who had higher total ventilation-free days (p = 0.02), were decannulated earlier (p = 0.03) and discharged earlier (p = 0.0089). Conclusion ET had significant benefits in reduction of postoperative morbidities with overall shorter mechanical ventilation, LOICUS, and LOHS, better nutrition supplementation, lesser infection, etc. These benefits may promote faster patient convalescence and rehabilitation with reduced hospital costs.

Objective.Determine whether daily bathing with chlorhexidine-based soap decreased methicillin-resistant Staphylococcus aureus (MRSA) transmission and intensive care unit (ICU)-acquired S. aureus infection among ICU patients.Design.Prospective pre-post-intervention study with control unit.Setting.A 1,250-bed tertiary care teaching hospital.Patients.Medical and surgical ICU patients.Methods.Active surveillance for MRSA colonization was performed in both ICUs. In June 2005, a chlorhexidine bathing protocol was implemented in the surgical ICU. Changes in S. aureus transmission and infection rate before and after implementation were analyzed using time-series methodology.Results.The intervention unit had a 20.68% decrease in MRSA acquisition after institution of the bathing protocol (12.64 cases per 1,000 patient-days at risk before the intervention vs 10.03 cases per 1,000 patient-days at risk after the intervention; β, −2.62 [95% confidence interval (CI), −5.19 to −0.04]; P = .046). There was no significant change in MRSA acquisition in the control ICU during the study period (10.97 cases per 1,000 patient-days at risk before June 2005 vs 11.33 cases per 1,000 patient-days at risk after June 2005; β, −11.10 [95% CI, −37.40 to 15.19]; P = .40). There was a 20.77% decrease in all S. aureus (including MRSA) acquisition in the intervention ICU from 2002 through 2007 (19.73 cases per 1,000 patient-days at risk before the intervention to 15.63 cases per 1,000 patient-days at risk after the intervention [95% CI, −7.25 to −0.95]; P = .012)]. The incidence of ICU-acquired MRSA infections decreased by 41.37% in the intervention ICU (1.96 infections per 1,000 patient-days at risk before the intervention vs 1.15 infections per 1,000 patient-days at risk after the intervention; P = .001).Conclusions.Institution of daily chlorhexidine bathing in an ICU resulted in a decrease in the transmission of S. aureus, including MRSA. These data support the use of routine daily chlorhexidine baths to decrease rates of S. aureus transmission and infection.

Introduction: When sudden cardiac arrest occurs in non-resuscitation focused care settings, bedside clinicians may not intervene prior to dedicated resuscitation team arrival. As perceived self-efficacy (SE) contributes to cognitive functioning, facilitating effective intervention, we developed and evaluated a mock code training approach, First Five (FF) , to enhance bedside responders’ resuscitation task SE using an entity’s defibrillator and manikin. Self-efficacy is knowing that one can perform actions in principle and envision performing the steps to reach a goal. Hypotheses: Participants’ resuscitation SE will improve after FF training; 2) Inpatient (IP) and Ambulatory Care Center (ACC) providers will differ in their pre-SE and post-SE in response to FF training. Methods: Participants enrolled from ACCs and medical-surgical IP units at a large, urban tertiary care hospital from May 2018 to April 2019 completed a de-identified 10-point Likert-scale SE survey before and after they were trained to perform initial bedside resuscitation tasks (Figure 1 x-axis labels). Matched, complete, pre/post data for 85 in-hospital and 107 ACC participants were analyzed via repeated measures multivariate analysis of variance. Results: Patterns of reported change in the seven resuscitation task SE measures of IP personnel differed significantly from those of ACC personnel [Pillai’s Trace = .222, F(7,184)=7.483, p=.0005, partial η 2 = .222]. In both settings, post-session SE measures increased significantly from pre-session SE measures [Pillai’s Trace = .588, F(7,184)=37.438, p=.0005, partial η 2 = .588]. Moreover, though ACC providers consistently reported lower pre-training SE resuscitation task scores, post-training scores from both settings were comparable (Figure 1). Conclusions: First Five training is effective in enhancing resuscitation task SE among inpatient and ambulatory care setting providers that are not resuscitation-focused.
