Abstract There has been an increasing tendency of infections caused by multidrug-resistant organisms (MDRO), including multidrug-resistant Acinetobacter baumannii (MDRAB), in the Rīga East University Hospital (REUH) during the last decade. Over the last two years (2014-2015), this tendency has reversed and the prevalence of MDRAB has decreased considerably. In this study we assessed the prevalence of MDRAB in intensive care units (ICUs), internal medicine, surgery units and analysed antibiotic sensitivity profiles. In addition, we determined if current infection control measures are preventing further increase of infections caused by MDRAB in REUH. Retrospective Acinetobacter baumannii prevalence data were collected for the period from 2009 until 2012. For the time period from the beginning of 2013 until 2015, after implementing such infection control measures as control of compliance to hand hygiene guidelines, a review of central venous catheter insertion protocols and regular search for sources of MDRAB in hospital environment, prospective follow-up of new cases was conducted. Antimicrobial sensitivity profiles were assessed for the period from 2013 until 2015. Data were processed with the statistical software WHONET 5.5. Bacteria identification and antibiotic susceptibility testing were performed by VITEK 2 compact, BioMerieux, France. The prevalence of MDRAB in the period 2009 to 2013 increased from 71 to 217 cases per year, but from between 2013 (time of implementing infection control measures) and 2015 it decreased to 113 cases in 2015. In the three year period (2013-2015), the proportion of MDRAB causing bloodstream infections (BSI) and central nervous system infections (CNSI) was 15.85% from all identified MDRAB cases. Of the 113 MDRAB infections diagnosed in 2015, BSI was found in 16.81% cases (n = 19). Antibiotic resistance testing showed that colistin is the most effective drug against MDRAB. The majority of Acinetobacter baumannii isolates were resistant to Ampicillin/Sulbactam, Piperacillin/Tazobactam, Ceftazidime, Cefepime, Imipenem, Meropenem, Amikacin, Gentamicin, Tobramycin, and Ciprofloxacin. Over the last two years (2014-2015), prevalence of MDRAB infections decreased considerably. In the time period from 2013 to 2014, resistance of Acinetobacter baumannii increased to imipenem, ciprofloxacin and colistin, while decreased slightly to amikacin. Rigorous infection control measures, such as identification and elimination of new MDRAB sources in environment, review of the central venous catheter insertion protocol and improvements in hand hygiene, are crucial for decreasing distribution of and invasive infections caused by MDRAB in the hospital environment.

Infection Control Measures

Abstract Nosocomially acquired completely resistant Acinetobacter baumannii strains are a major clinical concern. We identified completely resistant A. baumannii in 6 (4.9%) of 122 A. baumannii isolates in a retrospective chart review at two teaching hospitals. All of these patients had received broad-spectrum antibiotics and had severe underlying comorbid illnesses, long hospitalizations, or recent surgical procedures; 3 had been in the intensive care unit. Five (83%) of the 6 patients were older than 70 years. Only one death occurred. Strict infection control measures may limit further spread.

Clonal Spread

We characterized two epidemiologically similarAcinetobacter baumanniiclusters from two separate intensive care units (ICU) using core genome multilocus sequence typing. Clonal spread was confirmed in ICU-1 (12 of 14 isolates shared genotypes); in ICU-2, all genotypes (13 isolates) were diverse, thus excluding transmissions and enabling adequate infection control measures.

Background: Management of ventilator-associated pneumonia (VAP) in critically ill patients is a challenge to intensivists. This study aimed at identifying microbial factors and infection control practices that influenced incidence of VAP in a tertiary care hospital.Methods: Incidence of VAP among patients admitted to the intensive care units (ICU) from January to December 2016 was estimated. A one year period of study was divided into 3 segments of January to April, May to August, and September to December. Isolation rates of Gram Negative Bacteria (GNB) from respiratory samples and their extensively drug resistance (XDR) pattern were also analyzed.Results: A total of 14 patients had developed VAP. Incidence of VAP in the 1st, 2nd and 3rd segments of the year was 25.3, 15.2 and 4.1/1000 ventilator days respectively. Acinetobacter baumannii was the causative agent in all patients (100%). Among all GNB isolated the rate of Acinetobacter baumannii was 83%, 64%, 59% during the 3 segments of the year. XDR strains were 76%, 62% and 55%. Interventional factors like improvement in infection control practices which included hand hygiene, cohorting of MDR/XDR infected patients and environmental surveillance was noted.Conclusions: The VAP incidence declined in the later part of the year than the earlier (25.3 Vs 4.1/1000 ventilator days), with a notable decrease in the isolation of Acinetobacter baumannii (p value-0.005) and XDR organisms (p value-0.01). Directly proportionate association of VAP incidence with microbial factors were noted. Infection control measures to curtail MDR organisms should be an important component in the management of patients on ventilators.

AbstractA prospective study was undertaken to determine colonization rates, susceptibility profiles, and outcomes in patients with clinical isolates of Acinetobacter baumannii. Fifty percent of patients became colonized with A baumannii, and 29% of these patients had clinical and colonizing isolates with discordant susceptibility profiles, without apparent relation to antibiotic use. Barrier infection control measures are necessary to prevent nosocomial transmission.
