This pathogen very rarely causes neonatal sepsis. The most common infections caused by Pantoea SPP are septic arthritis or synovitis, meningitis frequently complicated by brain abscess, upper respiratory infections, and peritonitis. We present the case of a premature infant who presented neonatal respiratory distress and whose evolution was complicated by the occurrence of a nosocomial infection for which a blood culture was performed isolating the germ Pantoea SPP. The patient’s management was initially centered on non-invasive ventilation with antibiotherapy based on carbapenem and aminoglycoside. Due to the clinical and biological worsening, the neonate was intubated and sedated and put on colymicin. The evolution was unfavorable marked by a death at 16<sup>th</sup> days of life. Considering the high pathogenicity of this germ and its multi-resistance to antibiotics, it is crucial to know the clinical spectrum of Panteoa SPP infections in neonatal intensive care units, in order to palliate the fulminant evolution of multifocal attacks due to this germ.展开更多

More patients with emergency surgery suffer from open wounds and serious pollution, and operation time is relatively long. Thus, orthopedic patients with surgical incision infection account for a large proportion of incidence of hospital infection. Orthopedic patients are also bedridden for long periods, and they receive poor bone tissue blood supply. In surgical incision infections, mild cases suffer from delayed wound healing, whereas severe cases can form osteomyelitis. This study reviews progress of research on risk factors of nosocomial infection among orthopedic patients in recent years.展开更多

Methods: A pre-post intervention study was conducted in a 280-bed hospital in Spain. In the year 2008 we implemented perioperative insulin protocols aimed at blood glucose values from 80 to 180 mg/dL. Surgical patients with diabetes admitted on year 2009 (intervention group) were compared with a control group of patients with diabetes admitted for surgery on year 2007, matched 1:1 by traditional wound class. Results: We analyzed 96 patients. Implemented protocols were followed in 48% of patients intra-operatively and 75% of patients postoperatively. Patients in the intervention group had reductions in blood glucose at surgery 150 +/- 61 mg/dL vs. 172 +/- 53 mg/dL;p = 0.05), greater proportion of target glucose values throughout hospitalization (67% vs. 55%;p = 0.07), and reductions in the incidence of nosocomial infections after controlling for confounders (Odds Ratio: 0.20;95% Confidence intervals: 0.06 - 0.72;p = 0.014) when they were compared with the control group: The incidence of hypoglycemia was similar between two groups (0.12% vs. 0.10%, p = 0.867), respectively. Conclusion: Although our protocol needs improvements to increase implementation it was useful to control blood glucose safely and for reducing nosocomial infections.展开更多

METHODS Adult patients(> 18 years) admitted over 1-year, to a 24-bed medical critical care unit in India, were enrolled prospectively. Treatment cost and outcome data were collected. This cost data was merged with HAI data collected prospectively by the Hospital Infection Control Committee. Only infections occurring during ICU stay were included. The impact of HAI on treatment cost and mortality was assessed. RESULTS The mean(± SD) age of the cohort(n = 499) was42.3 ± 16.5 years. Acute physiology and chronic health evaluation-Ⅱ score was 13.9(95%CI: 13.3-14.5); 86% were ventilated. ICU and hospital length of stay were 7.8 ± 5.5 and 13.9 ± 10 d respectively. Hospital mortality was 27.9%. During ICU stay, 76(15.3%) patients developed an infection(ventilator-associated pneumonia 50; bloodstream infection 35; urinary tract infections 3), translating to 19.7 infections/1000 ICU days. When compared with those who did not develop an infection, an infection occurring during ICU stay was associated with significantly higher treatment cost [median(inter-quartile range, IQR) INR 92893(USD 1523)(IQR 57168-140286) vs INR 180469(USD 2958)(IQR 140030-237525); P < 0.001 and longer duration of ICU(6.7 ± 4.5 d vs 13.4 ± 7.0 d; P < 0.01) and hospital stay(12.4 ± 8.2 d vs 21.8 ± 13.9 d; P < 0.001)]. However ICU acquired infections did not impact hospital mortality(31.6% vs 27.2%; P = 0.49).CONCLUSION An infection acquired during ICU stay was associated with doubling of treatment cost and prolonged hospitalization but did not significantly increase mortality.展开更多

The purpose of this research was to study hospital infections in selected hospitals of Qazvin. Methods and Materials: This was an analytic-cross-sectional study. The research population consisted of 25,628 hospitalized patients in the first eight months of 2012 in three selected hospitals of the Qazvin Province. The algorithm of reporting hospital infections, the National Program of Controlling Hospital Infections, and 223 patient files hospitalized due to hospital-acquired infections were used to collect information. The collected information was analyzed using the SPSS V. 17 software;the descriptive statistics was used to analyze the qualitative variables;and the descriptive statistics together with chi-square and t-test were employed for the quantitative variables. Results: The ICU units had the most cases of hospital infections. Respiratory pneumonia and urinary infections topped the list of hospital infections. The most invasive treatments carried out on patients with hospital infections were surgery, urinary catheter, and venous catheter, respectively. More than 50 percent of patients with hospital infections were hospitalized for 2 to 21 days. Results and Conclusions: Because of the high rate of hospital infections, especially in the ICU ward, authorities must give top priority in their plans to designing suitable educational programs to inform hospital staff and patients of hospital infections and to provide suitable resources for dealing with this problem.展开更多

National Healthcare Safety Network along with Centers for Disease Control for surveillance has classified nosocomial infection sites into 13 types with 50 infection sites, which are specific on the basis of biological and clinical criteria. The agents that are usually involved in hospitalacquired infections include Streptococcus spp., Acinetobacter spp., enterococci, Pseudomonas aeruginosa, coagulase-negative staphylococci, Staphylococcus aureus, Bacillus cereus, Legionella and Enterobacteriaceae family members, namely, Proteus mirablis, Klebsiella pneumonia, Escherichia coli, Serratia marcescens. Nosocomial pathogens can be transmitted through person to person, environment or contaminated water and food, infected individuals, contaminated healthcare personnel's skin or contact via shared items and surfaces. Mainly, multi-drug-resistant nosocomial organisms include methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Pseudomonas aeruginosa and Klebsiella pneumonia, whereas Clostridium difficile shows natural resistance. Excessive and improper use of broadspectrum antibiotics, especially in healthcare settings, is elevating nosocomial infections, which not only becomes a big health care problem but also causes great economic and production loss in the community. Nosocomial infections can be controlled by measuring and comparing the infection rates within healthcare settings and sticking to the best healthcare practices. Centers for Disease Control and Prevention provides the methodology for surveillance of nosocomial infections along with investigation of major outbreaks. By means of this surveillance, hospitals can devise a strategy comprising of infection control practices.展开更多

To determine the factors that contribute to these infections, this study assessed medical staff compliance with hand hygiene measures and procedures. Method: This research was a cross-sectional and observational study conducted from February 15 to March 31, 2016 through direct and cautious observation of 47 members of the medical and paramedical staff. The study variables were hand washing before entering the neonatal unit and before entering each treatment room, hand washing before and after seeing each patient, compliance with hand washing steps, the use of hydroalcoholic solutions and adhering to the ban on mobile phone use inside the treatment room. Results: Only 15% of the medical staff followed all of the rules and measures governing hand hygiene. The result showed that 76.6% of them did not wash their hands before entering the unit;32% washed their hands before each care session;95.7% washed their hands after each care session;and 85% did not comply with the hand washing steps. Only 21.3% of the personnel used hydroalcoholic solution, and only 85% of the personnel adhered to the ban on mobile phone use within the treatment room. Conclusion: Compliance with hand hygiene measures is insufficient. These low compliance rates facilitate the occurrence of nosocomial infections. Nosocomial infections could be prevented by identifying the reasons that medical personnel do not wash their hands and by implementing a program for education/awareness on hygiene measures based on an analysis of errors and care procedures and sustained by regular evaluations.展开更多

文摘Aim: To evaluate the safety and effectiveness of a pilot program to control perioperative blood glucose in patients with diabetes. Methods: A pre-post intervention study was conducted in a 280-bed hospital in Spain. In the year 2008 we implemented perioperative insulin protocols aimed at blood glucose values from 80 to 180 mg/dL. Surgical patients with diabetes admitted on year 2009 (intervention group) were compared with a control group of patients with diabetes admitted for surgery on year 2007, matched 1:1 by traditional wound class. Results: We analyzed 96 patients. Implemented protocols were followed in 48% of patients intra-operatively and 75% of patients postoperatively. Patients in the intervention group had reductions in blood glucose at surgery 150 +/- 61 mg/dL vs. 172 +/- 53 mg/dL;p = 0.05), greater proportion of target glucose values throughout hospitalization (67% vs. 55%;p = 0.07), and reductions in the incidence of nosocomial infections after controlling for confounders (Odds Ratio: 0.20;95% Confidence intervals: 0.06 - 0.72;p = 0.014) when they were compared with the control group: The incidence of hypoglycemia was similar between two groups (0.12% vs. 0.10%, p = 0.867), respectively. Conclusion: Although our protocol needs improvements to increase implementation it was useful to control blood glucose safely and for reducing nosocomial infections.

文摘AIM To study the impact of hospital-acquired infections(HAIs) on cost and outcome from intensive care units(ICU) in India. METHODS Adult patients(> 18 years) admitted over 1-year, to a 24-bed medical critical care unit in India, were enrolled prospectively. Treatment cost and outcome data were collected. This cost data was merged with HAI data collected prospectively by the Hospital Infection Control Committee. Only infections occurring during ICU stay were included. The impact of HAI on treatment cost and mortality was assessed. RESULTS The mean(± SD) age of the cohort(n = 499) was42.3 ± 16.5 years. Acute physiology and chronic health evaluation-Ⅱ score was 13.9(95%CI: 13.3-14.5); 86% were ventilated. ICU and hospital length of stay were 7.8 ± 5.5 and 13.9 ± 10 d respectively. Hospital mortality was 27.9%. During ICU stay, 76(15.3%) patients developed an infection(ventilator-associated pneumonia 50; bloodstream infection 35; urinary tract infections 3), translating to 19.7 infections/1000 ICU days. When compared with those who did not develop an infection, an infection occurring during ICU stay was associated with significantly higher treatment cost [median(inter-quartile range, IQR) INR 92893(USD 1523)(IQR 57168-140286) vs INR 180469(USD 2958)(IQR 140030-237525); P < 0.001 and longer duration of ICU(6.7 ± 4.5 d vs 13.4 ± 7.0 d; P < 0.01) and hospital stay(12.4 ± 8.2 d vs 21.8 ± 13.9 d; P < 0.001)]. However ICU acquired infections did not impact hospital mortality(31.6% vs 27.2%; P = 0.49).CONCLUSION An infection acquired during ICU stay was associated with doubling of treatment cost and prolonged hospitalization but did not significantly increase mortality.
文摘Introduction: Hospital infections prolong patient hospitalization, necessitate additional treatment, increase mortality rate, raise hospital expenses, and even reduce the level of health in the society. The purpose of this research was to study hospital infections in selected hospitals of Qazvin. Methods and Materials: This was an analytic-cross-sectional study. The research population consisted of 25,628 hospitalized patients in the first eight months of 2012 in three selected hospitals of the Qazvin Province. The algorithm of reporting hospital infections, the National Program of Controlling Hospital Infections, and 223 patient files hospitalized due to hospital-acquired infections were used to collect information. The collected information was analyzed using the SPSS V. 17 software;the descriptive statistics was used to analyze the qualitative variables;and the descriptive statistics together with chi-square and t-test were employed for the quantitative variables. Results: The ICU units had the most cases of hospital infections. Respiratory pneumonia and urinary infections topped the list of hospital infections. The most invasive treatments carried out on patients with hospital infections were surgery, urinary catheter, and venous catheter, respectively. More than 50 percent of patients with hospital infections were hospitalized for 2 to 21 days. Results and Conclusions: Because of the high rate of hospital infections, especially in the ICU ward, authorities must give top priority in their plans to designing suitable educational programs to inform hospital staff and patients of hospital infections and to provide suitable resources for dealing with this problem.

文摘Nosocomial infections are also known as hospital-acquired/associated infections. National Healthcare Safety Network along with Centers for Disease Control for surveillance has classified nosocomial infection sites into 13 types with 50 infection sites, which are specific on the basis of biological and clinical criteria. The agents that are usually involved in hospitalacquired infections include Streptococcus spp., Acinetobacter spp., enterococci, Pseudomonas aeruginosa, coagulase-negative staphylococci, Staphylococcus aureus, Bacillus cereus, Legionella and Enterobacteriaceae family members, namely, Proteus mirablis, Klebsiella pneumonia, Escherichia coli, Serratia marcescens. Nosocomial pathogens can be transmitted through person to person, environment or contaminated water and food, infected individuals, contaminated healthcare personnel's skin or contact via shared items and surfaces. Mainly, multi-drug-resistant nosocomial organisms include methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Pseudomonas aeruginosa and Klebsiella pneumonia, whereas Clostridium difficile shows natural resistance. Excessive and improper use of broadspectrum antibiotics, especially in healthcare settings, is elevating nosocomial infections, which not only becomes a big health care problem but also causes great economic and production loss in the community. Nosocomial infections can be controlled by measuring and comparing the infection rates within healthcare settings and sticking to the best healthcare practices. Centers for Disease Control and Prevention provides the methodology for surveillance of nosocomial infections along with investigation of major outbreaks. By means of this surveillance, hospitals can devise a strategy comprising of infection control practices.
文摘Objective: Despite the presence of hand washing material and the training given to medical staff regarding hygiene measures and health care procedures in October 2015, the prevalence of nosocomial infections in the neonatal unit of the National University Teaching Hospital of Cotonou (CNHU-Cotonou) was estimated at 8% in January 2016. To determine the factors that contribute to these infections, this study assessed medical staff compliance with hand hygiene measures and procedures. Method: This research was a cross-sectional and observational study conducted from February 15 to March 31, 2016 through direct and cautious observation of 47 members of the medical and paramedical staff. The study variables were hand washing before entering the neonatal unit and before entering each treatment room, hand washing before and after seeing each patient, compliance with hand washing steps, the use of hydroalcoholic solutions and adhering to the ban on mobile phone use inside the treatment room. Results: Only 15% of the medical staff followed all of the rules and measures governing hand hygiene. The result showed that 76.6% of them did not wash their hands before entering the unit;32% washed their hands before each care session;95.7% washed their hands after each care session;and 85% did not comply with the hand washing steps. Only 21.3% of the personnel used hydroalcoholic solution, and only 85% of the personnel adhered to the ban on mobile phone use within the treatment room. Conclusion: Compliance with hand hygiene measures is insufficient. These low compliance rates facilitate the occurrence of nosocomial infections. Nosocomial infections could be prevented by identifying the reasons that medical personnel do not wash their hands and by implementing a program for education/awareness on hygiene measures based on an analysis of errors and care procedures and sustained by regular evaluations.
