Recently non-fermenting Gram negative rods (NFGNR) are playing an important role in healthcare associated infections. This observational study in a tertiary care hospital of Dhaka city conducted during 01August 2007 to 30 June 2013 found that 34.8% isolated organisms from patients with healthcare associated infections were NFGNR. Majority (74.3 %) of these infections were occurring inside critical care areas. Pseudomonas and Acinetobacter together constituted 79.6% of the total NFGNR whereas Burkholderia cephacia complex (15.4%), Stenotrophomonas (4.3%) and Chryseobacterium species (0.7%) combined constituted remaining 20.4%. Out of total NFGNRs, Pseudomonas was responsible for highest number of catheter associated urinary tract infections (55.6%), ventilator associated pneumonia (46.3%), respiratory tract infection (65.8%) and surgical site infection (70.6%). Blood stream infection was predominantly caused by Burkholderia cephacia complex (33.5%) and Acinetobacter spp. (39.5%). Other than colistin most of the organisms were resistant to antibiotics commonly recommended for NFGNR.DOI: http://dx.doi.org/10.3329/bjmm.v7i2.19326 Bangladesh J Med Microbiol 2013; 07(02): 6-12

Major Clinical Problem

Species of the Acinetobacter represent opportunistic bacteria with a growing clinical significance for Healthcare-associated infections (HAIs). In this literature review, we focus on the current role of Acinetobacter in infectious pathology and describe taxonomy, pathogenicity, and antibiotic resistance of these bacteria. Pathogenesis and regulation of virulence factors in Acinetobacter spp. are described in detail. The majority of acinetobacterial infections are associated with A. baumannii and occur predominantly in an immunocompromised host. Usually, acinetobacterial  infections  are characterized by local purulent inflammation; in severe cases, meningitis and sepsis may develop. Antibiotic resistance of Acinetobacter is a major clinical problem; therefore we give special attention to laboratory testing of resistance to antibiotics as well as identification of Acinetobacter.

Introduction: Healthcare-associated infections are of great socio-economic importance and are characterized by a large number of different pathogens. Nontuberculous mycobacteria are ubiquitous microorganisms that can circulate in a medical organization. The purpose of this review of epidemiologic studies was to establish the main features of mycobacteriosis as a healthcare-associated infection, taking into account the significance of the results and the compliance of the reviewed studies with the criteria of evidence-based medicine. Methods: We did a key word search for “nontuberculous mycobacteria”, “healthcare-associated infections”, and “mycobacteriosis” in several electronic bibliographic databases including Web of Science, PubMed, eLIBRARY, and ResearchGate and selected 127 out of 342 search results. Having analyzed the selected articles, we decided to include 34 of them in this study according to the topic of work. We established that nontuberculous mycobacteria can be found in various objects of health facilities, e.g. water supply systems, medical products and equipment. We also found that mycobacterial infection of nosocomial etiology could have various clinical manifestations (arthritis, keratitis, circulatory and skin diseases, etc.) determined by various aspects, such as heterogeneity of the group of nontuberculous mycobacteria, portals of entry (surgical procedures on various organs and systems of the human body, etc.), pathways of exposure and transmission factors. Resistance of nontuberculous mycobacteria to a number of disinfectants is a special question defining the importance of profound research in terms of ensuring sanitary and anti-epidemic (disinfection) safety within health facilities. Conclusions: Our findings indicate that mycobacterial infection can be considered as a healthcare-associated infection requiring an in-depth assessment from various perspectives including a microbiological monitoring of medical objects, statistical accounting of nosocomial infections, and clinical alertness in the diagnosis of mycobacteriosis by attending physicians and bacteriologists, etc.

Over the past two decades, the resistance to antibiotics, especially for Gram-negative bacteria, has increased at an alarming rate, requiring constant concern for resolving and controlling this extremely important therapeutic aspect in any medical department but in particular, in Anaesthesia and Intensive Care Units, in units of neonatology, paediatrics, neurosurgery, burned patients and immunosuppressed. Specialists note a particular concern for the resistance of Enterobacteriaceae to third-generation cephalosporins and aztreonam, with a resistance profile frequently associated with the expression of extended-spectrum �-lactamases (ESBL). The Enterobacter genus comprises 14 species, but two are of medical interest, Enterobacter aerogenes and E. cloacae, which are involved in inducing healthcare-associated infections such as urinary tract infections, pneumonia associated with mechanical ventilation, bacteremia, septicemia, etc. The purpose of the study was to highlight the antibiotic molecules in which microbial resistance of some circulating strains of enterobacteria was detected. A descriptive and retrospective study was conducted between 2012-2017, on a batch of 35 patients, admitted to the Sf. Maria Emergency Clinical Hospital for Children of Iasi, from whom various pathological products were collected to highlight the Enterobacter sp strains involved in the production of infections associated with the inpatient medical care. The antimicrobial sensitivity of each strain was determined by diffusimetric method, while the interpretation criteria were considered to be those of the laboratory standards. Most cases were reported in 2017 (31.42%). The majority were registered in new-borns (42.85%) and infants (25.71%). The Anaesthesia and Intensive Care Units and Neonatology Anaesthesia and Intensive Care Units departments were the most involved. Microbial antibacterial resistance of Enterobacter sp isolates showed that all manifested resistance to ampicillin, amoxicillin and clavulanic acid, 48.57% were resistant to Cefuroxime, 42.85% resistant to Ceftazidime and Ceftriaxone, 14.28% to ciprofloxacin, 11.42% to ertapenem, 5.71% to Meronem. Although it showed relatively few cases with infections associated with healthcare in which strains of Enterobacter sp. were isolated our study, which was carried out over a period of 5 years, provides useful indications regarding the prevalence of healthcare associated infections with Enterobacter sp in paediatric patients and guidelines for antibiotic therapy.

Background: Healthcare-associated infections (HCAIs) occur when patients receiving treatment in a health care setting develop an infection. They represent a major public health problem, requiring the integration of clinical medicine, pathology, epidemiology, laboratory sciences, and, finally, forensic medicine. Methods: The determination of cause of death is fundamental not only in the cases of presumed malpractice to ascertain the causal link with any negligent behavior both of health facilities and of individual professionals, but also for epidemiological purposes since it may help to know the global burden of HCAIs, that remains undetermined because of the difficulty of gathering reliable diagnostic data. A complete methodological approach, integrating clinical data by means of autopsy and histological and laboratory findings aiming to identify and demonstrate the host response to infectious insult, is mandatory in HCAIs related deaths. Results: Important tasks for forensic specialists in hospitals and health services centers are the promotion of transparency and open communication by health-care workers on the risk of HCAIs, thus facilitating patients’ engagement and the implementation of educational interventions for professionals aimed to improve their knowledge and adherence to prevention and control measures. Conclusion: HCAIs are a major problem for patient safety in every health-care facility and system around the world and their control and prevention represent a challenging priority for healthcare institution and workers committed to making healthcare safer. Clinicians are at the forefront in the war against HCAIs, however, also forensic pathologists have a remarkable role.

Background: The NHSN is the nation’s largest surveillance system for healthcare-associated infections. Since 2011, acute-care hospitals (ACHs) have been required to report intensive care unit (ICU) central-line–associated bloodstream infections (CLABSIs) to the NHSN pursuant to CMS requirements. In 2015, this requirement included general medical, surgical, and medical-surgical wards. Also in 2015, the NHSN implemented a repeat infection timeframe (RIT) that required repeat CLABSIs, in the same patient and admission, to be excluded if onset was within 14 days. This analysis is the first at the national level to describe repeat CLABSIs. Methods: Index CLABSIs reported in ACH ICUs and select wards during 2015–2108 were included, in addition to repeat CLABSIs occurring at any location during the same period. CLABSIs were stratified into 2 groups: single and repeat CLABSIs. The repeat CLABSI group included the index CLABSI and subsequent CLABSI(s) reported for the same patient. Up to 5 CLABSIs were included for a single patient. Pathogen analyses were limited to the first pathogen reported for each CLABSI, which is considered to be the most important cause of the event. Likelihood ratio χ2 tests were used to determine differences in proportions. Results: Of the 70,214 CLABSIs reported, 5,983 (8.5%) were repeat CLABSIs. Of 3,264 nonindex CLABSIs, 425 (13%) were identified in non-ICU or non-select ward locations. Staphylococcus aureus was the most common pathogen in both the single and repeat CLABSI groups (14.2% and 12%, respectively) (Fig. 1). Compared to all other pathogens, CLABSIs reported with Candida spp were less likely in a repeat CLABSI event than in a single CLABSI event (P < .0001). Insertion-related organisms were more likely to be associated with single CLABSIs than repeat CLABSIs (P < .0001) (Fig. 2). Alternatively, Enterococcus spp or Klebsiella pneumoniae and K. oxytoca were more likely to be associated with repeat CLABSIs than single CLABSIs (P < .0001). Conclusions: This analysis highlights differences in the aggregate pathogen distributions comparing single versus repeat CLABSIs. Assessing the pathogens associated with repeat CLABSIs may offer another way to assess the success of CLABSI prevention efforts (eg, clean insertion practices). Pathogens such as Enterococcus spp and Klebsiella spp demonstrate a greater association with repeat CLABSIs. Thus, instituting prevention efforts focused on these organisms may warrant greater attention and could impact the likelihood of repeat CLABSIs. Additional analysis of patient-specific pathogens identified in the repeat CLABSI group may yield further clarification.Funding: NoneDisclosures: None
