Emergence of bacterial antimicrobial resistance (AMR) is a major concern across the globe. Infections with multidrug resistant organisms (MDRO’s) increase the morbidity and mortality in addition to financial costs, especially in vulnerable patients. Knowing the profile of MDRO’s in a particular region or institution helps in optimal and timely antibiotic therapy, which is a key factor in avoiding the selection pressure exerted on microorganisms. In this study, microbiological profile of significant MDRO’s isolated over a period of two years were analysed retrospectively. 58% of the total isolates were classified as MDRO’s. Intensive care units (ICU’s) contributed to a significantly higher number of MDRO’s than other departments (p<0.001). Methicillin resistance was seen in 54% of the Staphylococcus aureus isolates. Carbapenem resistance was encountered widely amongst members of the genus enterobacteriaceae (approximately 40% isolates of Klebsiella spp. and Enterobacter spp.) and Acinetobacter spp. (78%). This study emphasizes the fact that AMR burden is high in low- and middle-income countries (LMIC’s) and that a concerted effort on the part of legislators, medical community and general public is required to address the issue. Keywords: Antimicrobial resistance, MDRO profile, carbapenem resistance.

Apropos to the article by Dr Bali, titled “Mupirocin resistance in clinical isolates of methicillin-sensitive and resistant Staphylococcus aureus in a tertiary care centre of North India” (1), the authors have raised important issue of emerging antimicrobial resistance (AMR). Antimicrobial resistance is an increasingly serious threat to global public health that requires action across all government sectors and society. As per WHO, AMR lurks the effective prevention and management of an ever-increasing spectrum of infections caused by bacteria, parasites, fungi and viruses. Novel resistance mechanisms are emerging and spreading globally, threatening the man’s ability to treat common infectious diseases.

Background: My tertiary-care hospital is a 750-bed hospital with only 17 airborne infection isolation room (AIIR) and negative-pressure rooms to isolate patients who have been diagnosed or are suspected with prevalent diseases like tuberculosis, measles, and chickenpox. On the other hand, only 14 single-patient isolation rooms are available to isolate patients with multidrug-resistant organisms (MDROs) such as CRE (carbapenum-resistant Enterobacter) or colistin-resistant MDROs. Due to the limited number of isolation rooms, the average number of hours to isolate infected patients was ~20 hours, which ultimately directly placed healthcare workers (HCWs) at risk of exposure to infected patients. Methods: Plan-Do-Study-Act (PDSA) quality improvement methodology was utilized to decrease the average number of hours to isolate infected patients and to reduce the exposure of HCWs to communicable diseases. A detailed analysis were performed to identify root causes and their effects at multiple levels. A multidisciplinary team implemented several strategies: coordination with information and technology team to place isolation alerts in the charting system; screening flyers and questions at emergency department triage; close coordination with admission and bed management office; daily morning and evening rounds by infection preventionists in the emergency department; daily morning meeting with microbiology and bed management office to intervene immediately to isolate patients in a timely way; infection preventionist on-call system (24 hours per day, 7 days per week) to provide recommendations for patient placement and cohorting of infected patients wherever possible. Results: In 1 year, a significant reduction was achieved in the number of hours to isolate infected patients, from 20 hours to 4 hours. As a result, HCW exposures to communicable diseases also decreased from 6.7 to 1.5; HCW exposures to TB decreased from 6.0 to 1.9; exposures measles decreased from 4.75 to 1.5; and exposures chickenpox decreased from 7.3 to 1.0. Significant reductions in cost incurred by the organization for the employees who were exposed to these diseases for postexposure prophylaxis also decreased, from ~Rs. 290,000 (~US$3,000) to ~Rs. 59,520 (~US$600). Conclusions: This multidisciplinary approach achieved infection prevention improvements and enhanced patient and HCW safety in a limited-resource setting.Funding: NoneDisclosures: None

Background: Staphylococcus aureus is a frequent cause of infections involving the bloodstream, skin and soft tissue, and lungs in hospitalized patients. These isolates are often multidrug resistant and represent a major therapeutic challenge. Objective: To explore the susceptibilities of S. aureus to nafcillin/oxacillin, a surrogate for methicillin resistance, and the fluoroquinolones and determine whether a relationship might exist between fluoroquinolone use and the prevalence of methicillin-resistant S. aureus (MRSA). Methods: To date, 353 institutions throughout the US and Puerto Rico have enrolled in the Antimicrobial Resistance Management (ARM) Program, and data have been submitted on nearly 5 million isolates of S. aureus. Isolates submitted from 1990 through 2002 were reviewed for sensitivity to nafcillin/oxacillin, clindamycin, erythromycin, and the fluoroquinolones ciprofloxacin and levofloxacin. Results: From 1990 through 2002 inclusive, susceptibility to nafcillin/oxacillin nationally was 64.9% (n = 360,460), ranging from 62.2% in the North Central and Northeast US to 72.8% in the Southwest. Nationally, S. aureus isolates were more resistant to levofloxacin (41.4%, n = 123,868) than ciprofloxacin (38.7%, n = 256,178). The greatest change in susceptibility of S. aureus to nafcillin/oxacillin and ciprofloxacin occurred concurrently from 1998 to 2002, which may implicate fluoroquinolone use with increasing rates of MRSA infection. Conclusions: Resistance to methicillin and the fluoroquinolones has increased in concert during the past 5 years. Collectively, data from the ARM Program, along with several other investigations, support a role of fluoroquinolone use in the emergence of MRSA. These observations, along with increasing resistance among gram-positive and gram-negative pathogens, underscore the need for judicious use of fluoroquinolones.

Background: Incidence of multidrug resistant Klebsiella pnumoniae infections are increasing globally especially in ICUs. Aim: We evaluated the burden of colistin resistant K. pneumoniae (ColR KP) and the risk factors associated with the outcome of these patients. Methods: Consecutive patients developing K. pneumoniae infections were included. K. pneumoniae from endotracheal tube and catheterized urine sample, having cell count <105 cfu/ml, and which did not necessitate a change in antibiotics as per the treating physicians was considered as colonizer. Demographic and clinical details were collected and samples were processed as per standard protocol. Any growth was identified and its antimicrobial susceptibility was carried out by using Vitek 2 automated system. Minimum inhibitory concentration of >4 μg/ml for Colistin was considered as resistant. The resistant isolates were confirmed with Broth microdilution method. Risk factor associated with the outcome of ColR KP was analyzed. Findings: Burden of K. pneumoniae infection was 50.02 per 1000 admissions. K. pneumonie (n=155) was isolated from patients with ventilator associated pneumonia (84, 54.2%), followed by blood stream infection (49, 31.6%) and urinary tract infection (22, 14.2%). ColR KP and intermediate (ColI KP) isolates were 58 (37.41%) and 97 (62.6%) respectively. Among ColR KP infected patients 32 (55.1%) died whereas 26 (44.8%) patients were discharged. Higher mortality was witnessed in ColI KP cases (75, 77.3%) compared to ColR-KP cases (32, 55.1%) (p=0.004; OR=2.77; 95% CI=1.37 to 5.59). Colistin resistance and presence of central line were independently associated with mortality. Conclusion: Colistin resistant K. pneumoniae infections among ICU patients are on rise. Presence of central venous catheter and resistance to colistin were independent predictors of mortality.

Objective. To define the antimicrobial resistance profiles of the microorganisms most commonly isolated from hospitalized adult patients in Dominican Republic (DR). Methods. A retrospective, cross-sectional study of phenotypic antimicrobial susceptibility patterns was conducted using data from 3 802 clinical microbiology reports specifying positive bacterial cultures in samples collected from patients admitted to the clinical, surgery, and intensive care units (ICU) at three tertiary-level care hospitals in the city of Santiago de los Caballeros from 1 January 2016 – 31 December 2017. Descriptive statistics and chi-square test (P ≤ 0.05) were used to analyze the qualitative variables. Results. At the three hospitals, there were 932, 1 090, and 1 780 microbiology reports analyzed. Of the total, 1274 were from the ICU, 1 042 from the surgery unit, and 1 486 from the clinical unit. Methicillin resistance was found in 57.3% of the Staphylococcus aureus isolates and 75.3% of the coagulase-negative staphylococci. Third-generation cephalosporin resistance was detected in 54.4% of isolates identified as members of the Enterobacteriaceae family, 67.3% of the Acinetobacter spp., and 91.7% of the Pseudomonas, while carbapenem resistance was shown by 8.0%, 23.8%, and 51.0% of these, respectively. Most of the resistant Acinetobacter spp. isolates were found in just one hospital and the prevalence of Enterobacteriaceae resistant to carbapenems was highest in the ICU. Conclusion. Antimicrobial resistance levels are high among hospitalized patients in Dominican Republic and may cause enhanced risk factors that impact clinical outcomes. Urgent measures are needed to address antimicrobial resistance in DR.

1 2 ABSTRACT The aim: To obtain the first estimates of the current prevalence rate of episiotomy infections in the puerperium and antimicrobial resistance of responsible pathogens in Ukraine. Materials and methods: We performed a retrospective multicenter cohort study was based on surveillance data. The study population consisted of all women who had a vaginal delivery in 7 Regional Women’s Hospitals of Ukraine. Definitions of episiotomy infections were used from the Centers for Disease Control and Prevention’s National Healthcare Safety Network (CDC/NHSN). Results: Total 35.6% women after vaginal delivery had episiotomy done. The prevalence rate of episiotomy infections was 17.7%. The predominant pathogens were: Escherichia coli (49.2%), Enterobacter spp. (11.1%), Streptococcus spp. (9.1%), Enterococcus faecalis (6.5%), Klebsiella spp. (8.1%), followed by Pseudomonas aeruginosa (4.7%), Staphylococcus aureus (4.2%), Proteus spp.(2.9%) and Staphylococcus epidermidis (2.8%). The overall proportion of methicillin-resistance was observed in 17.3% of Staphylococcus aureus (MRSA). Vancomycin resistance was observed in 6.8% of isolated enterococci. Carbapenem resistance was identified in 8% of P.aeruginosa isolates. Resistance to third-generation cephalosporins was observed in 15.2% Klebsiella spp. and E.coli 16.4% isolates. The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 26.4%. The prevalence of ESBL production among E. coli isolates was significantly higher than in K. pneumoniae (31.4%, vs 12.5%). Conclusions: Episiotomy infections in the puerperium are common in Ukraine and most of these infections caused by antibiotic-resistant bacteria. Optimizing the management and empirical antimicrobial therapy may reduce the burden of episiotomy infections, but prevention is the key element.
