Risk factors for carbapenem-resistant Klebsiella pneumoniae infections in Intensive Care Units: a multicentre case-control study with a competing-risks analysis.

Aim: This study investigated the risk factors for the development of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections in adult patients in Intensive Care Units (ICUs). Methods: A multicentre case-control study was conducted in ICUs in three tertiary hospitals in Turkey. The cases were patients culture-confirmed CRKP and a condition associated with healthcare-associated infections. Two controls were randomly selected for each case from among all other patients with an ICU stay at least as long as that of the corresponding case-patient. A proportional semiparametric subdistribution hazards regression model was used to assess risk factors for CRKP infection. ICU discharge and non-CRKP-related deaths were treated as competing risks. Results: A total of 120 patients, 44 cases and 76 controls were included in the analysis. Of the controls, 32 were discharged from the ICU and 44 died without acquiring CRKP infection. Endotracheal intubation (hazard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.00-3.868) and type 2 diabetes mellitus (HR: 1.57, 95% CI: 0.888-2.806) were associated with an increased risk of CRKP infection, whereas carbapenem exposure (HR: 0.47, 95% CI: 0.190-1.1175) and the presence of a nasogastric tube (HR: 0.49, 95% CI: 0.277-0.884) were associated with a decreased risk of CRKP infection. Conclusions: Enteral nutrition support via a nasogastric tube may be associated with a reduced risk of CRKP-resistant infections in ICU patients. This hypothesis should be tested with a well-designed study.

Neostigmine versus sugammadex on post-operative recovery following bariatric surgery.

OBJECTIVE: The purpose of our study was to compare the recovery characteristics and side effects of sugammadex (SM) and neostigmine (NT) in morbidly obese patients undergoing bariatric surgery. Residual neuromuscular block is a serious condition that increases pulmonary complications after anesthesia. Although acetylcholinesterase inhibitors help reverse this block, they may be insufficient, especially when administered with inhalational anesthetics. SM, a selective antagonist, may be more effective in reversing the block. METHODS: Patients were randomly divided into NT group (Group NT, n=34) and SM group (Group SM, n=34).For the induction, fentanil (1-1.5 µ/kg), propofol (2-3 mg/kg), and rocuronium (0.6 mg/kg) were used.For the maintenance, 50% O2 + air, 1% sevoflurane, and remifentanil (0.5-0.3 µg/kg/min) were used. Additional rocuronium was given to maintain the train of four (TOF) ratio ≤2. On completion of surgery and when the TOF ratio was 2, group NT received 50 µg/kg of NT with 20 µg/kg of atropine, whereas group SM received 2 mg/kg of SM. Hemodynamic parameters and peripheral oxygen saturation (SpO2) were recorded every 10 minfirst, and every 5 min after the reversal agents were given. When the TOF ratio was 0.9 or higher, time to reach a TOF ratio of 0.9, and time to extubation were recorded. Patients were observed in the recovery room for 30 min for adverse effects. RESULTS: Demographic characteristics of the patients and total rocuronium use in two groups were similar (p>0.05).Time to extubation, time to TOF ratio of 0.9, time until patients responded to stimuli, time until cooperation, and time until orientation were significantly shorter in the SM group than in the NT group. Time to reach the Aldrete score of 9 was also significantly shorter in the SM group (p<0.05).In the post-operative period, hemodynamic variables and side effects such asrespiratory difficulty, nausea, vomiting, hypo/hypertension, and presence of pain showed no statistically significant differences between the groups (p>0.05). CONCLUSION: Considering the high risk of post-operative respiratory insufficiency inmorbidly obese patients, SM could be a safer choice in this patient group.

Effectiveness of ozone therapy in addition to conventional treatment on mortality in patients with COVID-19.

AIM: In this study, we aimed to investigate the effectiveness of ozone therapy, which is one of the integrative medicine applications that has been used safely for many years, on the prevalence of mortality in patients receiving COVID-19 treatment. METHODS: This was a prospective, controlled study conducted on patients with COVID-19 who were hospitalised. In this study, 55 patients were included. The patients were divided into two groups as the ozone and control group. Ozone therapy (major autohemotherapy) was applied to 37 patients who were being treated with the appropriate COVID-19 treatment protocol determined by the infectious diseases committee of our hospital. The ozone treatment protocol consisted of seven sessions (one session per day) of intravenous ozone administration, applied in a volume of 100 mL and a concentration of 30 µg/mL. Only the conventional COVID-19 treatment protocol was applied to 18 patients in the control group. Clinical follow-up was performed until the discharge of the patients from the hospital with successful treatment or until the mortality occurred. Factors affecting mortality were analysed using univariate regression analysis. RESULTS: Intensive care unit (ICU) hospitalisation was required in 6 of the 37 patients who were treated with ozone (16.2%), while 4 of 18 patients in the control group required ICU treatment (22.2%) (P = .713). When the mortality rates between the two groups were compared, mortality was lower in the ozone group (P = .032). As a result of univariate logistic regression analysis performed to investigate the factors affecting mortality, treatment with ozone therapy was determined as a risk factor for mortality. Patients receiving ozone therapy appear to have a lower mortality risk (odds ratio [OR]: 0.149, 95% confidence interval [CI] 0.026-0.863, P = .034). CONCLUSION: In this study, the findings suggested that the administration of ozone therapy along with the conventional medical treatment in patients hospitalised for COVID-19 could reduce mortality.

Postoperative Analgesic Efficacy of Preemptive and Postoperative Lornoxicam or Tramadol in Lumbar Disc Surgery.

OBJECTIVE: To compare preemptive and postoperative analgesic efficacy of tramadol and lornoxicam administered before anaesthesia induction in lumbar discectomy. METHODS: This randomised, double-blind trial was conducted on 60 ASA I and II patients undergoing lumbar discectomy. Group L (n=30) received 3×8 mg day-1 lornoxicam, and Group T (n=30) received 3×1.5 mg kg-1 day-1 tramadol. A verbal rating scale (VRS), the duration of effective analgesia, the number of additional analgesics used, adverse effects and patient satisfaction were evaluated at the postoperative 30th minute and 1st, 2nd, 4th, 6th, 8th, 12th and 24th hours. RESULTS: There were no significant differences between Groups L and T regarding demographic and clinical characteristics, the number of additional analgesics and the duration of effective analgesia, adverse effects and patient satisfaction. VRS scores of the patients in Group T were significantly higher than those in Group L at the postoperative 30th minute (p=0.050) and the 1st hour (p=0.005). CONCLUSION: Lornoxicam, which was used for preemptive and postoperative analgesia in lumbar disc surgery, had provided adequate and effective analgesia such as tramadol. Moreover, preemptive analgesia was quite effective in prevention and treatment of postoperative pain.

Comparison of bilevel positive airway pressure and average volume-assured pressure support mode in terms of patient compliance and treatment success in hypercapnic patients. A cross-sectional study.

AIM: It is necessary for an effective NIV application to provide proper modality selection, sufficient minute ventilation (MV), also the amount of leakage on the circuit must be minimized and patient-ventilator adaptation must be achieved. METHODS: 30 patients with acute respiratory failure as a result of either internal or postoperative reasons were included in the study. Patient comfort was analyzed with a scale ranging from 0 to 2. Firstly the patient was used for two hours in BIPAP modality, after then the AVAPS modality (Period Av) was applied by setting the required rates the same mask. During BIPAP and AVAPS, arterial blood gases analysis, comfort scale and hemodynamic parameters were recorded in the 30th minute, 1st hour and 2nd hour. RESULTS: According to the assessment of arterial blood gases, the pH changes of both periods were statistically significant compared to their baseline values (p=0.001). Treatment compliance of the patients was significantly better at AVAPS modality at all times (p = 0.015, p = 0.008, p = 0.008, respectively). CONCLUSIONS: According to the results obtained from this study, the AVAPS modality has positive effects on pH and gas variation and patient comfort; therefore, it can be confidently used in clinical practice. KEY WORDS: Average Volume Assured Pressure Support, Bilevel Continuous Positive Airway Pressure, Intensive Care Units, Noninvasive Ventilation, Patients Compliance.

Comparison of RIVA and infraclavicular block in forearm and hand surgery.

OBJECTIVE: The aim of this study was to compare 2 techniques that are widely used in hand, wrist, and forearm: regional intravenous anesthesia (RIVA) and infraclavicular brachial block. METHODS: A total of 100 patients who were aged 18 to 85 years and who underwent hand, wrist, or forearm surgery of at least 30 minutes duration were included. RIVA was applied to Group 1 patients with administration of 40 mL of prilocaine (3 mg/kg). Ultrasonography-guided infraclavicular block was performed on Group 2 patients with 20 mL of 1% prilocaine. Several aspects of these 2 methods were compared, including length of time required to apply anesthesia, the analgesic effectiveness of the treatment during administration and in the peroperative and postoperative periods. RESULTS: The rate of mild and complete sensory loss was significantly higher in Group 2 at 10th and 15th minutes than in Group 1. The number scoring less than grade 2 using modified Bromage grading system in Group 2 was considerably greater than in Group 1. Processing time to apply the block was significantly longer in Group 1 compared with Group 2. CONCLUSION: It was determined that infraclavicular brachial block is superior to the RIVA method with respect to length of time required to administer and ease of application.

Non-invasive mechanical ventilation after the successful weaning: a comparison with the venturi mask / Ventilação mecânica não invasiva após desmame bem-sucedido: uma comparação com a máscara de Venturi

Abstract Background and objectives: This study compared the rates of acute respiratory failure, reintubation, length of intensive care stay and mortality in patients in whom the non-invasive mechanical ventilation (NIMV) was applied instead of the routine venturi face mask (VM) application after a successful weaning. Methods: Following the approval of the hospital ethics committee, 62 patients who were under mechanical ventilation for at least 48 hours were scheduled for this study. 12 patients were excluded because of the weaning failure during T-tube trial. The patients who had optimum weaning criteria after the T-tube trial of 30 minutes were extubated. The patients were kept on VM for 1 hour to observe the hemodynamic and respiratory stability. The group of 50 patients who were successful to wean randomly allocated to have either VM (n = 25), or NIV (n = 25). Systolic arterial pressure (SAP), heart rate (HR), respiratory rate (RR), PaO2, PCO2, and pH values were recorded. Results: The number of patients who developed respiratory failure in the NIV group was significantly less than VM group of patients (3 reintubation vs. 14 NIV + 5 reintubation in the VM group). The length of stay in the ICU was also significantly shorter in NIV group (5.2 ± 4.9 vs. 16.7 ± 7.7 days). Conclusions: The ratio of the respiratory failure and the length of stay in the ICU were lower when non-invasive mechanical ventilation was used after extubation even if the patient is regarded as ‘successfully weaned’. We recommend the use of NIMV in such patients to avoid unexpected ventilator failure.

Resumo Justificativa e objetivos: Este estudo comparou as taxas de insuficiência respiratória aguda, reintubação, tempo de internação em UTI e mortalidade em pacientes sob ventilação mecânica não invasiva (VMNI) em vez da habitual máscara facial de Venturi (MV) após desmame bem-sucedido. Métodos: Após a aprovação do Comitê de Ética do hospital, 62 pacientes que estavam sob ventilação mecânica por no mínimo 48 horas foram inscritos neste estudo. Doze foram excluídos devido à falha de desmame durante o teste de tubo-T. Os que apresentaram critérios de desmame ótimos após o teste de tubo-T de 30 minutos foram extubados. Foram mantidos em MV por uma hora para observação da estabilidade hemodinâmica e respiratória. O grupo de 50 pacientes que obtiveram sucesso no desmame ventilatório foi alocado aleatoriamente para MV (n = 25) ou VNI (n = 25). Os valores de pressão arterial sistólica (PAS), frequência cardíaca (FC), frequência respiratória (FR), PaO2, PCO2 e pH foram registrados. Resultados: O número de pacientes que desenvolveu insuficiência respiratória no grupo VNI foi significativamente menor do que o do grupo MV (3 reintubações vs. 14 VNI + 5 reintubações no grupo MV). O tempo de permanência em UTI também foi significativamente menor no grupo NIV (5,2 ± 4,9 vs. 16,7 ± 7,7 dias). Conclusões: As taxas de insuficiência respiratória e do tempo de permanência em UTI foram menores quando a ventilação mecânica não invasiva foi usada após a extubação, mesmo se o paciente foi considerado como “desmame bem-sucedido”. Recomendamos o uso de VMNI em tais pacientes para evitar a falha inesperada do ventilador.

Rocuronium: automatic infusion versus manual administration with TOF monitorisation.

TOF (train-of-four) monitoring provides objective data in application of neuromuscular blocking agent. Thus, applicator-based differences are eliminated and optimum muscle relaxation is maintained during operation. In the present study, we aimed to compare the effects of target-controlled infusion system and standard TOF monitoring, on use of rocuronium. ASA I-II patients, who were aged between 18 and 75 years and scheduled for elective abdominal surgery at Haydarpasa Numune Training and Research Hospital, were enrolled in the study. In order to evaluate neuromuscular blockade, the patients in Group 1 were connected to the acceleromyography device of the target-controlled infusion pump (Veryark-CLMRIS-I-China) while the ones in Group 2 were connected to the routinely used acceleromyography device (TOF Watch SX). There was no significant difference between groups regarding patient characteristics, the durations of anaesthesia and surgery, quality of intubation, time to extubation and time to recovery (TOF ratio of 0.9). Intubation time was significantly longer in Group 1 (Automated group) as compared to Group 2 (Control group) (p < 0.05). The total rocuronium amount used in Group 1 was found to be significantly higher than the amount used in Group 2 (p < 0.05). There was no clinical evidence of residual neuromuscular blockage or reoccurrence of neuromuscular blockage in any patient in either group. Both methods can be used for administration of neuromuscular blocker agent during moderate time anesthesia. No advantage was noted when rocuronium was administered via automatical infusion pump during anaesthesia.

Diagnostic value of sTREM-1 and procalcitonin levels in the early diagnosis of sepsis.

OBJECTIVE: Sepsis is still major cause of morbidity and mortality, despite improvements in diagnosis and treatment in modern medicine. Therefore, laboratory examinations that provide correct and rapid results are needed to support the diagnosis. This study was conducted to investigate value of immunological indicators procalcitonin (PCT) and soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in differential diagnosis of patients with sepsis and systemic inflammatory response syndrome (SIRS), as well as to assess their importance in determining prognosis of patients with sepsis. METHODS: Total of 90 patients, 38 with SIRS and 52 with sepsis, who were between the ages 20 to 92, were included in this prospectively planned study. Blood sample was collected from the patients during hospitalization and again in follow-up visit. Enzyme-linked immunosorbent assay (MyBioSource, Inc., San Diego, CA, USA) was used to measure sTREM-1, and PCT was measured using mini VIDAS B.R.A.H.M.S PCT assay (Biomerieux, S.A., Marcy-l'Étoile, France). In addition, patients were clinically assessed using Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system. RESULTS: On day of intensive care unit admission, sTREM-1 and PCT levels, as well as APACHE II score were significantly higher in sepsis group than SIRS group (p=0.001, p=0.01, p=0.001, respectively). Values of sTREM-1 and APACHE II score were higher in the patients with positive blood cultures than those with negative culture results (p=0.002, p=0.006, respectively). PCT, C-reactive protein, and sTREM-1 levels were significantly higher in nonsurviving group. In differentiation of SIRS from sepsis, sTREM-1 cut-off value ≥133 pg/mL and PCT cut-off value of 1.57 ng/mL yielded sensitivity of 71.1% and 67.33%, and specificity of 73.3% and 65.79%, respectively. CONCLUSION: In patients with suspected sepsis, sTREM-1 and PCT can be used as indicators, in addition to scoring systems such as APACHE II and Sepsis-related Organ Failure Assessment score. However, it would be appropriate to support present findings with studies of larger series.

The comparison of ProSeal and I-gel laryngeal mask airways in anesthetized adult patients under controlled ventilation.

OBJECTIVES: To compare the insertion time, ease of device insertion, ease of gastric tube insertion, airway leakage pressure, and complications between the laryngeal mask airway (LMA) ProSeal (P-LMA) and I-gel (I-gel) groups. METHODS: Eighty patients with age range 18-65 years who underwent elective surgery were included in the study. The study took place in the operation rooms of Haydarpasa Numune Hospital, Istanbul, Turkey from November 2013 to April 2014. Patients were equally randomized into 2 groups; the I-gel group, and the P-LMA group. In both groups, the same specialist inserted the supraglottic airway devices. The insertion time of the devices, difficulty during insertion, difficulty during gastric tube insertion, coverage of airway pressure, and complications were recorded. RESULTS: The mean insertion time in the I-gel group was significantly lower than that of the P-LMA group (I-gel: 8±3; P-LMA: 13±5 s). The insertion success rate was higher in the I-gel group (100%, first attempt) than in the P-LMA group (82.5%, first attempt). The gastric tube placement success rate was higher in the I-gel group (92.5%, first attempt) than in the P-LMA group (72.5%, first attempt). The airway leakage pressures were similar. CONCLUSION: Insertion was easier, insertion time was lower, and nasogastric tube insertion success was higher with the I-gel application, and is, therefore, the preferred LMA.

Impact of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Hand Hygiene Approach, over 8 years, in 11 cities of Turkey.

AIMS: To evaluate the effectiveness of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Hand Hygiene Approach in Turkey and analyse predictors of poor hand hygiene compliance. DESIGN: An observational, prospective, interventional, before-and-after study was conducted from August 2003 to August 2011 in 12 intensive care units (ICU) of 12 hospitals in 11 cities. The study was divided into a baseline and a follow-up period and included random 30-minute observations for hand hygiene compliance in ICU. The hand hygiene approach included administrative support, supplies availability, education and training, reminders in the workplace, process surveillance, and performance feedback. RESULTS: We observed 21,145 opportunities for hand hygiene. Overall hand hygiene compliance increased from 28.8% to 91% (95% CI 87.6-93.0, p 0.0001). Multivariate and univariate analyses showed that several variables were significantly associated with poor hand hygiene compliance: males vs. females (39% vs. 48%; 95% CI 0.79-0.84, p 0.0001), ancillary staff vs. physicians (35% vs. 46%, 95% CI 0.73-0.78, p 0.0001), and adult vs. pediatric ICUs (42% vs. 74%, 95% CI 0.54-0.60, p 0.0001). CONCLUSIONS: Adherence to hand hygiene was significantly increased with the INICC Hand Hygiene Approach. Specific programmes should be directed to improve hand hygiene in variables found to be predictors of poor hand hygiene compliance.

International Nosocomial Infection Control Consortium (INICC) national report on device-associated infection rates in 19 cities of Turkey, data summary for 2003-2012.

BACKGROUND: Device-associated healthcare-acquired infections (DA-HAI) pose a threat to patient safety, particularly in the intensive care unit (ICU). We report the results of the International Infection Control Consortium (INICC) study conducted in Turkey from August 2003 through October 2012. METHODS: A DA-HAI surveillance study in 63 adult, paediatric ICUs and neonatal ICUs (NICUs) from 29 hospitals, in 19 cities using the methods and definitions of the U.S. NHSN and INICC methods. RESULTS: We collected prospective data from 94,498 ICU patients for 647,316 bed days. Pooled DA-HAI rates for adult and paediatric ICUs were 11.1 central line-associated bloodstream infections (CLABSIs) per 1000 central line (CL)-days, 21.4 ventilator-associated pneumonias (VAPs) per 1000 mechanical ventilator (MV)-days and 7.5 catheter-associated urinary tract infections (CAUTIs) per 1000 urinary catheter-days. Pooled DA-HAI rates for NICUs were 30 CLABSIs per 1000 CL-days, and 15.8 VAPs per 1000 MV-days. Extra length of stay (LOS) in adult and paediatric ICUs was 19.4 for CLABSI, 8.7 for VAP and 10.1 for CAUTI. Extra LOS in NICUs was 13.1 for patients with CLABSI and 16.2 for patients with VAP. Extra crude mortality was 12% for CLABSI, 19.4% for VAP and 10.5% for CAUTI in ICUs, and 15.4% for CLABSI and 10.5% for VAP in NICUs. Pooled device use (DU) ratios for adult and paediatric ICUs were 0.54 for MV, 0.65 for CL and 0.88 for UC, and 0.12 for MV, and 0.09 for CL in NICUs. The CLABSI rate was 8.5 per 1,000 CL days in the Medical Surgical ICUs included in this study, which is higher than the INICC report rate of 4.9, and more than eight times higher than the NHSN rate of 0.9. Similarly, the VAP and CAUTI rates were higher compared with U.S. NHSN (22.3 vs. 1.1 for VAP; 7.9 vs. 1.2 for CAUTI) and with the INICC report (22.3 vs. 16.5 in VAP; 7.9 vs. 5.3 in CAUTI). CONCLUSIONS: DA-HAI rates and DU ratios in our ICUs were higher than those reported in the INICC global report and in the US NHSN report.

Impact of a multidimensional infection control approach on central line-associated bloodstream infections rates in adult intensive care units of 8 cities of Turkey: findings of the International Nosocomial Infection Control Consortium (INICC).

BACKGROUND: Central line-associated bloodstream infections (CLABs) have long been associated with excess lengths of stay, increased hospital costs and mortality attributable to them. Different studies from developed countries have shown that practice bundles reduce the incidence of CLAB in intensive care units. However, the impact of the bundle strategy has not been systematically analyzed in the adult intensive care unit (ICU) setting in developing countries, such as Turkey. The aim of this study is to analyze the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach to reduce the rates of CLAB in 13 ICUs of 13 INICC member hospitals from 8 cities of Turkey. METHODS: We conducted active, prospective surveillance before-after study to determine CLAB rates in a cohort of 4,017 adults hospitalized in ICUs. We applied the definitions of the CDC/NHSN and INICC surveillance methods. The study was divided into baseline and intervention periods. During baseline, active outcome surveillance of CLAB rates was performed. During intervention, the INICC multidimensional approach for CLAB reduction was implemented and included the following measures: 1- bundle of infection control interventions, 2- education, 3- outcome surveillance, 4- process surveillance, 5- feedback of CLAB rates, and 6- performance feedback on infection control practices. CLAB rates obtained in baseline were compared with CLAB rates obtained during intervention. RESULTS: During baseline, 3,129 central line (CL) days were recorded, and during intervention, we recorded 23,463 CL-days. We used random effects Poisson regression to account for clustering of CLAB rates within hospital across time periods. The baseline CLAB rate was 22.7 per 1000 CL days, which was decreased during the intervention period to 12.0 CLABs per 1000 CL days (IRR 0.613; 95% CI 0.43 - 0.87; P 0.007). This amounted to a 39% reduction in the incidence rate of CLAB. CONCLUSIONS: The implementation of multidimensional infection control approach was associated with a significant reduction in the CLAB rates in adult ICUs of Turkey, and thus should be widely implemented.

Alterations in bacterial spectrum and increasing resistance rates in isolated microorganisms from device-associated infections in an intensive care unit of a teaching hospital in Istanbul (2004-2010).

The aim of the present study was to determine the rate of device-associated infection (DAI) and the change in profiles and antimicrobial resistance patterns of the causative microorganisms in a medical-surgical intensive care unit (ICU), as well as to evaluate the effect of a new nationwide hospital infection control program (NHICP), which has been implemented in Turkey. In this study, 5,772 patients that were hospitalized for a total of 43,658 days acquired 1,321 DAIs, with an overall rate of 30.2% per 1,000 ICU days. Between 2004 (before the NHICP) and 2010, the incidence densities of catheter-associated urinary tract infection (CAUTI) decreased from 10.2 to 5.7 per 1,000 device-days (P < 0.0001), and central venous catheter-associated bloodstream infection (CVC-BSI) decreased from 5.3 to 2.1 per 1,000 device-days (P < 0.0001). However, ventilator-associated pneumonia increased from 27.0 to 31.5 per 1,000 device-days. Multidrug-resistant species rates increased from 5.8% to 76.6% (P < 0.0001) for Acinetobacter spp. and from 6.8% to 53.1% (P < 0.0001) for Pseudomonas aeruginosa. The extended-spectrum ß-lactamase-producing Enterobacteriaceae rate increased from 23.1% to 54.2% (P = 0.01); the vancomycin-resistance rate among Enterococcus spp. increased from 0% in 2004 to 12.5% in 2010 (P = 0.0003). In conclusion, while a significant decrease was achieved in the incidences of CAUTI and CVC-BSI, the NHICP was not completely effective in our ICU. The high incidence of DAI and the increasing prevalence of multidrug-resistant microorganisms indicate that further interventions are urgently needed.

Incidence, etiology and risk factors associated with mortality of nosocomial candidemia in a tertiary care hospital in Istanbul, Turkey.

OBJECTIVE: The aim of this study was to determine the incidence, etiology and risk factors for mortality of patients with nosocomial candidemia. SUBJECTS AND METHODS: This observational study was performed at Haydarpasa Numune Training and Research Hospital, a tertiary care hospital with 750 beds, between the years 2004 and 2007. Fifty defined cases with a nosocomial bloodstream infection caused by Candida species were included in the study. All demographic, microbiological and clinical records for each patient were collected using a standardized form. Blood culture was performed by automated blood culture system, and those samples positive for yeast were subcultured on Sabouraud agar. RESULTS: The mean incidence density of nosocomial candidemia was 0.58/10,000 patient-days/year (range 0.17-1.4). Candidemia episodes increased from 0.17/10,000 to 1.4/10,000 patient-days/year (p < 0.0001). Candida albicans and non-albicans Candida accounted for 15 (30%) and 35 (70%) cases, respectively. The overall mortality was 56% and was significantly associated with stayingin the intensive care unit (odds ratio: 3.667, 95% confidence interval: 1.07-12.54, p = 0.034). CONCLUSION: This study showed that there was a significantly increased trend in the incidence of candidemia with high mortality during the study period.

Incidence, etiology, and antibiotic resistance patterns of gram-negative microorganisms isolated from patients with ventilator-associated pneumonia in a medical-surgical intensive care unit of a teaching hospital in istanbul, Turkey (2004-2006).

The identification of microorganisms causing ventilator-associated pneumonia (VAP) is important for formulating appropriate therapies. In this study, we report the incidence, etiology, and antibiotic resistance patterns of Gram-negative microorganisms isolated from patients diagnosed with VAP in our medical-surgical intensive care unit (ICU) during the years 2004-2006. VAP was diagnosed by using the clinical criteria of the Centers for Disease Control and Prevention. Antibiotic resistance patterns of isolated microorganisms were defined by standard methods. The VAP incidence rate was 22.6/1,000 ventilator days. The most frequently isolated pathogens were Acinetobacter spp., methicillin-resistant Staphylococcus aureus, and Pseudomonas aeruginosa. Ninety percent of Acinetobacter spp. isolates were resistant to ceftazidime, 64% to imipenem, and 80% to ciprofloxacin. Fifty-nine percent of P. aeruginosa isolates were resistant to ceftazidime, 32% to imipenem, and 62% to ciprofloxacin. Cefoperazone-sulbactam was the most active agent against Acinetobacter spp. In conclusion, the incidence of VAP and the prevalence of multidrug-resistant microorganisms are quite high in our ICU. Comparison of the resistance rates of isolates demonstrates that certain antibiotic agents are more effective than others.
