Background: Since the early nineties, a new methicillin-resistant Staphylococcus aureus (MRSA) has existed in a form correlating with community health personnel. Community-acquired MRSA (CA-MRSA) could be differentiated from healthcare-associated MRSA (HA-MRSA) microbiologically, epidemiologically, and molecularly. Aims: To determine the prevalence, risk factors of MRSA infections in community and hospital. Settings: The incidence and risk factors for CA-MRSA and HA-MRSA among patients of medical, surgical, and pediatrics wards and ICU at a Kuwaiti teaching hospital between 1 March 2011 and 30 November 2011 were studied. Materials and Methods: Cultures for MRSA were taken from nasal (nostril), groin, axilla, wound, sputum, or throat, and the inguinal area in all enrolled patients upon admission. All preserved isolates were examined for their susceptibility to different types of antibiotics. Results and Conclusion: A total of 71 MRSA patients admitted to different hospital wards were examined. Among these patients, 52 (73.2%) were carriers of MRSA before they were admitted to the hospital. Nineteen patients (26.8%) were found to have acquired MRSA during their stay in the hospital. Twenty-nine patients (40.8%) were given mupirocin local skin antibiotic. Binomial and the t-test (paired) were used to compare the prevalence of CA-MRSA and HA-MRSA; significant correlation (P < 0.05) between the type of MRSA and different wards, sites, and lengths of hospital stay was found. The level of serum albumin that is routinely measured at hospital admission is a predictor to MRSA infection. This study suggests that S. aureus and MRSA should become a national priority for disease control to avoid outbreaks.

Background: Although scabies outbreaks in hospitals are frequent, the optimal approach to management of these outbreaks has not yet been defined. We describe a hospital scabies outbreak that was successfully controlled without ward closure. Methods: An outbreak of scabies at a teaching hospital and subsequent control measures were investigated. Outcomes included the number of cases affecting patients and staff, number of patients and staff requiring prophylaxis, duration of the outbreak, and cost of the outbreak. Outcomes were compared with those in a similar outbreak occurring at the same hospital 20 years earlier and with other published descriptions of hospital scabies outbreaks. Results: In January 2010, a patient who had undergone renal transplantation was admitted 3 times to St. Michael's Hospital, but a diagnosis of scabies was not considered until the final admission. Widespread exposure of patients and staff on 2 wards prompted the establishment of an outbreak management team. Initial interventions focused on isolation and treatment of the index case and on contact tracing to identify and treat secondary cases and to offer prophylaxis to direct contacts. Five symptomatic staff members and 2 patient cases were quickly identified, an outbreak was declared, and mass simultaneous prophylaxis was initiated on the 2 involved wards. A single case occurred 2 weeks after the mass prophylaxis program in a staff member who had not received the prophylaxis. Six weeks after the onset of symptoms, the end of the outbreak was declared. No additional cases have been reported up to the time of publication. The total cost of the outbreak was $20,000. Conclusions: Early recognition of crusted scabies is essential to prevent outbreaks. Once an outbreak occurs, prompt control of the index patient and rapid tracing of contacts to identify secondary cases are necessary. When prolonged exposure to a case of crusted scabies results in multiple secondary cases, institution of simultaneous mass prophylaxis is the most efficient strategy for terminating the outbreak and can be implemented without ward closure.

This study aims to examine patient wait times from triaging to physician assessment in the emergency department (ED) for non-emergent patients, and to see whether patient flow and process (triage) are impacted by aged patients. A retrospective study method was used to analyse 185 patients in three age groups. Key data recorded were triage level, wait time to physician assessment and ED census. Multiple linear regression analysis was used to determine the strength of association with increased wait time. A longer average wait time for all patients occurred when there was an increase in the number of patients aged ≥ 65 years in the ED. Further analysis showed 12.1% of the variation extending ED wait time associated with the triage process was explained by the number of patients aged ≥ 65 years. In addition, extended wait time, overcrowding and numbers of those who left without being seen were strongly associated (P < 0.05) with the number of aged patients in the ED. The effects of aged patients on ED structure and process have significant implications for nursing. Nursing process and practice sets clear responsibilities for nursing to ensure patient safety. However, the impact of factors associated with aged patients in ED, nursing's role and ED process can negatively impact performance expectations and requires further investigation. © 2010 Blackwell Publishing Asia Pty Ltd.

Background:Better depicting the relationship between antibiotic consumption and evolutionary healthcare-associated infections (HAIs) caused by multidrug-resistant Gram-negative bacilli (MDR-GNB) may help highlight the importance of antibiotic stewardship.Methodology/Principal Findings:The correlations between antibiotic consumption and MDR-GNB HAIs at a 2,700-bed primary care and tertiary referral center in Taiwan between 2002 and 2009 were assessed. MDR-GNB HAI referred to a HAI caused by MDR-Enterobacteriaceae, MDR-Pseudomonas aeruginosa or MDR-Acinetobacter spp. Consumptions of individual antibiotics and MDR-GNB HAI series were first evaluated for trend over time. When a trend was significant, the presence or absence of associations between the selected clinically meaningful antibiotic resistance and antibiotic consumption was further explored using cross-correlation analyses. Significant major findings included (i) increased consumptions of extended-spectrum cephalosporins, carbapenems, aminopenicillins/β-lactamase inhibitors, piperacillin/tazobactam, and fluoroquinolones, (ii) decreased consumptions of non-extended-spectrum cephalosporins, natural penicillins, aminopenicillins, ureidopenicillin and aminoglycosides, and (iii) decreasing trend in the incidence of the overall HAIs, stable trends in GNB HAIs and MDR-GNB HAIs throughout the study period, and increasing trend in HAIs caused by carbapenem-resistant (CR) Acinetobacter spp. since 2006. HAIs due to CR-Acinetobacter spp. was found to positively correlate with the consumptions of carbapenems, extended-spectrum cephalosporins, aminopenicillins/β-lactamase inhibitors, piperacillin/tazobactam and fluoroquinolones, and negatively correlate with the consumptions of non-extended-spectrum cephalosporins, penicillins and aminoglycosides. No significant association was found between the increased use of piperacilllin/tazobactam and increasing HAIs due to CR-Acinetobacter spp.Conclusions:The trend in overall HAIs decreased and trends in GNB HAIs and MDR-GNB HAIs remained stable over time suggesting that the infection control practice was effective during the study period, and the escalating HAIs due to CR- Acinetobacter spp. were driven by consumptions of broad-spectrum antibiotics other than piperacillin/tazobactam. Our data underscore the importance of antibiotic stewardship in the improvement of the trend of HAIs caused by Acinetobacter spp. © 2013 Chen et al.

Background Purpose of this study is to determine strategies to decrease catheter-associated urinary tract infection (CAUTI) in intensive care unit (ICU) patients.Methods ICU patients with an indwelling urinary catheter (UC) in one tertiary hospital were monitored for CAUTI. Interventions were implemented sequentially with quarterly data collection. Outcome measures were infection ratio (IR = number of infections/catheter days [CD] × 1000) and device utilization rate (DUR = catheter days/patient days).Results CDs and DUR decreased (fiscal year 2008: CD, 11,414; DUR,.85 vs fiscal year 2013: CD, 8,144; DUR,.70). IR increased with suspension of prepackaged baths (IR, 3.2 to 3.5 to 4.9 to 5.0), twice daily UC care (IR, 4.8 to 6.7), emptying UC bags at 400 mL (IR, 6.7 to 9.2). Two-person UC placement (IR, 5.6 to 4.8), physician notification of CAUTI (IR, 6.1 to 4.8), and reinstitution of prepackaged baths and daily UC care (IR, 4.8 to 3.7) decreased CAUTI rates.Conclusions Decreasing CAUTI in the ICU requires diligent monitoring and constant practice re-evaluation. Elimination of CAUTI in the ICU may not be possible. © 2014 Elsevier Inc.All rights reserved.
