Background: Bloodstream infection (BSI) is an increasing public health concern worldwide, representing a serious infection with significant morbidity and mortality, especially in children and the elderly. The predominant microbial distribution and antibiotic susceptibility were investigated among BSIs in the different intensive care units (ICUs)—pediatric ICU (PICU), surgical ICU (SICU), cardiac ICU (CICU), respiratory ICU (RICU), and geriatric ICU (GICU)—in order to achieve more efficient and appropriate therapies for patients in various ICUs.Methods: In this retrospective cross-sectional study, the blood specimens were collected from five different ICUs of Peking University First Hospital and comprehensive ICU of Miyun Teaching Hospital (Miyun ICU) before antimicrobial treatment from 2017 to 2020. Microorganism cultures of the blood samples were conducted, and positive cultures were tested for type of pathogens and drug susceptibility.Results: The prevalence of BSIs was the highest in the Miyun ICU (10.85%), followed by the RICU (9.48%) and the PICU (8.36%). The total prevalence of Gram-positive bacterial strains (especially Staphylococcus spp. and Enterococcus spp.) in the PICU (44.55%), SICU (57.58%), CICU (55.00%), GICU (49.06%), and Miyun ICU (57.58%) was higher than that of Gram-negative bacteria. The major bacterial strain was Acinetobacter baumannii in the PICU (21.82%); Klebsiella pneumoniae in the SICU (12.88%), CICU (30.00%), and RICU (30.39%); Escherichia coli in the GICU (20.75%); and Staphylococcus epidermidis (18.18%) in the Miyun ICU. Staphylococcus hominis of BSIs remained highly susceptible (>70%) to gentamicin, linezolid, daptomycin, teicoplanin, vancomycin, tigecycline, and rifampicin in all the ICUs. Its antibiotic sensitivity to levofloxacin was moderate in the PICU and CICU, but mild (<30%) in the SICU, RICU, and GICU. K. pneumoniae was highly susceptible to doxycycline, minocycline, and tigecycline in all the ICUs except the RICU, and its antibiotic sensitivity to imipenem, meropenem, amikacin, ciprofloxacin, and levofloxacin was high/moderate in the PICU, CICU, GICU, and Miyun ICU, but mild in the SICU and RICU.Conclusion: The current study demonstrated the distribution of prevalent microorganisms, and their antimicrobial susceptibility exhibited a high divergence among BSIs in different ICUs from a tertiary hospital and an outer suburban hospital in Beijing. Therefore, different antibiotic therapies for various wards and distinct age groups (especially between pediatric and elderly patients) should be considered to control the emergence and spread of highly antibiotic-resistant infections.

Abstract Background: Bloodstream infection (BSI) is an increasing public health concern worldwide, representing a serious infection with significant morbidity and mortality, especially in children and elderly. The predominant microbial distribution and antibiotic susceptibility were investigated among BSIs in the pediatric intensive care unit (PICU), surgical intensive care unit (SICU), cardiac intensive care unit (CICU), respiratory intensive care unit (RICU) and geriatric intensive care unit (GICU) in order to achieve more efficient and appropriate therapies for patients in various ICUs.Methods: In this retrospective cross-sectional study, 516 positive cultures out of 6597 （positive rate 7.82%）blood specimens among BSIs in the five ICUs from 2017 to 2020 were analyzed for pathogen incidence and drug-susceptibility.Results: The incidence of BSIs was the highest in the RICU (9.48%) followed by the PICU (8.36%). The total prevalence of Gram-positive (G+) bacterial strains (especially Staphylococcus spp. and Enterococcus spp.) in the PICU (44.55%), SICU (57.58%), CICU (55.00%) and GICU (49.06%) was higher than Gram-negative (G-) bacteria. The major bacterial strain was Acinetobacter baumannii (G-) in the PICU (21.82%), Klebsiella pneumoniae (G-) in the SICU (12.88%), CICU (30.00%) and RICU (30.39%), and Escherichia coli (G-) in GICU (20.75%). Staphylococcus hominis of BSIs remained highly susceptible (>70%) to gentamicin, linezolid, daptomycin, teicoplanin, vancomycin, tigecycline and rifampicin in all the ICUs. Its antibiotic sensitivity to levofloxacin was moderate in the PICU and CICU, but mild (<30%) in the SICU, RICU and GICU. K. pneumoniae was highly susceptible to doxycycline, minocycline, tigecycline in all the ICUs except RICU, and its antibiotic sensitivity to imipenem, meropenem, amikacin, ciprofloxacin and levofloxacin in the GICU was high/moderate in PICU, CICU and GICU, but mild in the SICU and RICU.Conclusions: The current study demonstrated the distribution of prevalent microorganisms and their antimicrobial susceptibility exhibited a high divergence among BSIs in PICU, SICU, CICU, RICU and GICU from a tertiary hospital in Beijing. Therefore, different antibiotic therapies for various wards and distinct age groups (especially between pediatric and elderly patients) should be considered to control the emergence and spread of highly antibiotic-resistant infections.

Abstract Background Hospital-acquired infections (HAIs) in intensive care units (ICUs) are among the avoidable morbidity and mortality causes. This study aimed at investigating the rate of ICU-acquired infections (ICU-AIs) in Iran. Methods For the purpose of this multi-center study, the rate of ICU-AIs calculated based on the data collected through Iranian nosocomial infections surveillance system and hospital information system. The data expanded based on 12 months of the year (13,632 records in terms of “hospital-ward-month”), and then, the last observation carried forward method was used to replace the missing data. Results The mean (standard deviation) age of 52,276 patients with HAIs in the ICUs was 47.37 (30.78) years. The overall rate of ICU-AIs was 96.61 per 1000 patients and 16.82 per 1000 patient-days in Iran’s hospitals. The three main HAIs in the general ICUs were ventilator-associated events (VAE), urinary tract infection (UTI), and pneumonia events & lower respiratory tract infection (PNEU & LRI) infections. The three main HAIs in the internal and surgical ICUs were VAE, UTI, and bloodstream infections/surgical site infections (BSI/SSI). The most prevalent HAIs were BSI, PNEU & LRI and eye, ear, nose, throat, or mouth (EENT) infections in the neonatal ICU and PNEU & LRI, VAE, and BSI in the PICU. Device, catheter, and ventilator-associated infections accounted for 60.96, 18.56, and 39.83% of ICU-AIs, respectively. The ventilator-associated infection rate was 26.29 per 1000 ventilator-days. Based on the Pabon Lasso model, the lowest rates of ICU-AIs (66.95 per 1000 patients and 15.19 patient-days) observed in zone III, the efficient area. Conclusions HAIs are common in the internal ICU wards. In fact, VAE and ventilator-related infections are more prevalent in Iran. HAIs in the ICUs leads to an increased risk of ICU-related mortality. Therefore, to reduce ICU-AIs, the specific and trained personnel must be responsible for the use of the devices (catheter use and ventilators), avoid over use of catheterization when possible, and remove catheters earlier.

Eol Care

Objective: Neonatal nurses face numerous barriers in providing end-of-life (EOL) care for neonates and their families. Addressing neonatal nurses’ attitudes could provide insight into barriers that impede neonatal palliative care (NPC). This study thus conducted to examine neonatal nurses’ attitude toward barriers in providing NPC in Southeast Iran. Method: In this cross-sectional study, a translated modified version of Neonatal Palliative Care Attitude Scale was used to examine attitudes of 70 nurses toward barriers of palliative care in 3 neonatal intensive care units in Southeast Iran. Results: Findings indicated that overall 42.63% of nurses were strongly agreed or agreed with the proposed barriers in NPC. Among all categories, the highest and the lowest scores belonged to the categories of “insufficient resources” (3.42 ± 0.65) and “inappropriate personal and social attitudes” (2.33 ± 0.48), respectively. Neonatal nurses who had less education and study regarding NPC reported the presence of more barriers to NPC in the categories of “inappropriate organizational culture” and/or “inadequate nursing proficiency.” Also, younger nurses had more positive attitudes toward the category of inappropriate organizational culture as being a barrier to provision of NPC (4.62). Conclusion: The findings suggest that developing a context-based instrument is required to represent the barrier more precisely. Neonatal palliative care can be improved by establishing a special environment to focus on infants’ EOL care. This establishment requires standard palliative care guidelines and adequate NPC-trained nurses.

Objective.Healthcare-associated infections (HAIs) are an important cause of morbidity and mortality worldwide. During the period from 2002 through 2004, a group of Italian hospitals was recruited to conduct HAI point-prevalence surveys.Design.Three point-prevalence surveys.Methods.A total of 9,609 patients were surveyed.Results.The overall frequency of HAI was 6.7% (645 infections among the 9,609 surveyed patients). The most frequent HAIs were lower respiratory tract infections, which accounted for 35.8% (231 of 645 HAIs) of all HAIs, followed by urinary tract infections (152 [23.6%] of 645 HAIs), bloodstream infections (90 [14.0%] of 645 HAIs), and surgical site infections (79 [12.2%] of 645 HAIs). In both multivariate and univariate analysis, invasive procedures, duration of stay, chemotherapy, trauma, coma, and the location of the hospital were all factors statistically significantly associated with the occurrence of an HAL Enterobacteriaceae were the most common isolates recovered in medical and surgical wards, whereas gram-negative aerobic bacilli were the most common isolates recovered in intensive care units. Approximately one-half of all of the patients surveyed were receiving antibiotics at the time of our study; the most used antibiotic classes were fluoroquinolones in medical wards, cephalosporins in surgical wards, and penicillins and glycopeptides in intensive care units.Conclusion.Our study emphasizes the need for implementing further HAI surveillance to provide the National Health System with proper tools to prevent and manage infection in hospitalized patients.

Abstract Candida bloodstream infections are associated with high mortality among critically ill patients in intensive care units (ICUs). Studies that explore the risk factors for candidemia may support better patient care in intensive care units. We conducted a retrospective, multicenter case-control study to investigate the risk factors for noncatheter-related Candida bloodstream infections (CBSI) in adult ICUs. Participants selected controls randomly on a 1:1 basis among all noncase patients stayed during the same period in ICUs. Data on 139 cases and 140 controls were deemed eligible. Among the controls, 69 patients died. The stratified Fine-Gray model was used to estimate the subdistribution Hazard ratios. The subdistribution hazards and 95% confidence intervals for final covariates were as follows: prior exposure to antimycotic agents, 2.21 (1.56–3.14); prior exposure to N-acetylcysteine, 0.11 (0.03–0.34) and prior surgical intervention, 1.26 (0.76–2.11). Of the patients, those exposed to antimycotic drugs, 87.1% (54/62) had breakthrough candidemia. Serious renal, hepatic, or hematologic side effects were comparable between patients those exposed and not-exposed to systemic antimycotic drugs. Untargeted administration of antimycotic drugs did not improve survival among candidemic patients (not-exposed, 63.6% [49/77]; exposed % 66.1 [41/62]; P = .899). This study documented that exposure to an antifungal agent is associated with increased the risk of subsequent development of CBSIs among nonneutropenic adult patients admitted to the ICU. Only two centers regularly prescribed N-acetylcysteine. Due to the limited number of subjects, we interpreted the positive effect of N-acetylcysteine on the absolute risk of CBSIs with caution.

Abstract Background The intensive care units are a high-risk environments for the occurrence of adverse events with serious consequences. The development of patient safety culture is a strategic focus to prevent these adverse events and improve patient safety and healthcare quality. This study aimed to assess patient safety culture in Tunisian intensive care units and to determine its associated factors. Methods It is a multicenter, descriptive cross-sectional study, among healthcare professionals of the intensive care units in the Tunisian center. The data collection was spread over a period of 2 months (October-November 2017). The measuring instrument used is the validated French version of the Hospital Survey On Patient Safety Culture questionnaire. Data entry and analysis was carried out by the Statistical Package for Social Sciences (SPSS 20.0) and Epi Info 6.04. Chi-square test was used to explore factors associated with patient safety culture. Results A total of 404 professionals participated in the study with a participation rate of 81.94%, spread over 10 hospitals and 18 units. All dimensions were to be improved. The overall perception of safety was 32.35%. The most developed dimension was teamwork within units with a score of 47.87% and the least developed dimension was the non-punitive response to error (18.6%). The patient safety culture was significantly more developed in private hospitals in seven of the 10 dimensions. Participants working in small units had a significantly higher patient safety culture. It has been shown that when workload is reduced the patient safety culture was significantly increased. Conclusions This study has shown that the patient safety culture still needs to be improved and allowed a clearer view of the safety aspects requiring special attention. Thus, improving patient safety culture. by implementing the quality management and error reporting systems could contribute to enhance the quality of healthcare provided to patients. Key messages The culture of culpability is the main weakness in the study. Encouraging event reporting and learning from errors s should be priorities in hospitals to enhance patient safety and healthcare quality.
