RESUMEN
BACKGROUND: Urinary tract infections (UTI) in men differ relevantly to women by their pathogens. Gram-positive uropathogens play a relevant role in UTI in men. In this study, we aimed to analyze the epidemiology of Enterococcus faecalis in UTI in male outpatients. METHODS: We conducted a retrospective observational multicenter study during 2015 to 2020 consisting of urine samples of 99,415 adult male outpatients sent from 6,749 outpatient practices from Germany. Proportions were compared using the z-Test and 95% confidence intervals were calculated using the Clopper-Pearson method. RESULTS: E. faecalis is the 2nd most frequent bacteria (16%) detected in suspected UTI in male outpatients. Young men are predominantly at risk (17%) for isolation of E. faecalis in suspected UTI. In polymicrobial infections E. faecalis is isolated in 47% of all suspected UTI in men. Recurrency of suspected UTI is significantly more frequent when E. faecalis is isolated compared to Escherichia coli (22% vs 26%; p < .001). Recurrency rates of E. faecalis associated UTI increases by age from 12% (18-29 years) to 28% ([Formula: see text] 70 years); p < .001. Congruently the resistance of E. faecalis against ciprofloxacin increases by age from 22% (18-29 years; 2019) to 37% ([Formula: see text] 70 years; 2019); p < .001. CONCLUSIONS: E. faecalis is frequently isolated in suspected UTI in male patients. Consequently, Nitrate-sticks results cannot be recommended to exclude UTI in men. The empirical use of ciprofloxacin in young adults can be reasonable. Frequent recurrences in E. faecalis associated suspected UTI emphasizes the importance of microbiological pathogen identification and susceptibility testing in men suffering from UTI.

A surgical site infection (SSI) is one of the most common surgical complications. This study analyzed different sources of microorganisms in the air, on reusable surgical instruments, and the outer surface of sterile packaging systems during the use and reprocessing of sterile goods (from the operating room (OR) to the Central Sterile Supply Department (CSSD)). The microbial load in the air was analyzed via active air sampling and settle plates. Furthermore, the airborne particle load was measured by a particle counter. Contact agar plates were used to determine the microbial load on surgical instruments and sterile packaging systems. The highest average microbial and particle load was measured in the air of the OR (active air sampling: max. 56 CFU/m3; settle plates: max. 9 CFU; ≥0.3 µm particles in size: 1,958,403 no./m3). However, no microbial load (0 CFU) was detected on surgical instruments sampled in the OR. The outer surface of stored sterile packaging systems showed a maximal microbial load of 64 CFU. The most common identified pathogen was coagulase-negative staphylococci. Compared to properly reprocessed reusable surgical instruments and sterile packaging systems, the air still seems to be the primary potential source of microbial contamination, especially within the OR.

BACKGROUND: The spread of SARS-CoV-2, multidrug-resistant organisms and other healthcare-associated pathogens represents supra-regional challenges for infection prevention and control (IPC) specialists in every European country. To tackle these problems, cross-site research collaboration of IPC specialists is very important. This study assesses the extent and quality of national research collaborations of IPC departments of university hospitals located in Austria, England, France, Germany, and the Netherlands, identifies network gaps, and provides potential solutions. METHODS: Joint publications of IPC heads of all university hospitals of the included countries between 1st of June 2013 until 31st of May 2020 were collected by Pubmed/Medline search. Further, two factors, the journal impact factor and the type/position of authorship, were used to calculate the Scientific Collaboration Impact (SCI) for all included sites; nationwide network analysis was performed. RESULTS: In five European countries, 95 sites and 125 responsible leaders for IPC who had been in charge during the study period were identified. Some countries such as Austria have only limited national research cooperations, while the Netherlands has established a gapless network. Most effective collaborating university site of each country were Lille with an SCI of 1146, Rotterdam (408), Berlin (268), Sussex (204), and Vienna/Innsbruck (18). DISCUSSION: The present study indicates major differences and room for improvement in IPC research collaborations within each country and underlines the potential and importance of collaborating in IPC.

BackgroundEvidence on the distribution of bacteria and therapy recommendations in male outpatients with urinary tract infections (UTI) remains insufficient.AimWe aimed to report frequency distributions and antimicrobial resistance (AMR) of bacteria causing UTI in men and to identify risk factors for resistance of Escherichia coli against trimethoprim (TMP) and ciprofloxacin (CIP).MethodsWe conducted a retrospective observational study using routinely collected midstream urine specimens from 102,736 adult male outpatients sent from 6,749 outpatient practices to nine collaborating laboratories from all major regions in Germany between 2015 and 2020. Resistance in E. coli was predicted using logistic regression.ResultsThe three most frequent bacteria were E. coli (38.4%), Enterococcus faecalis (16.5%) and Proteus mirabilis (9.3%). Resistance of E. coli against amoxicillin (45.7%), TMP (26.6%) and CIP (19.8%) was common. Multiple drug resistance was high (22.9%). Resistance against fosfomycin (0.9%) and nitrofurantoin (1.9%) was low. Resistance of En. faecalis against CIP was high (29.3%). Isolates of P. mirabilis revealed high resistance against TMP (41.3%) and CIP (16.6%). The CIP and TMP resistance was significantly higher among bacteria derived from recurrent UTI (p < 0.05). Age ≥ 90 years, recurrent UTI and regions East and South were independently associated with AMR of E. coli against TMP and CIP (p < 0.05).ConclusionThe most frequent UTI-causing pathogens showed highresistance against TMP and CIP, empirical therapy is therefore likely to fail. Apart from intrinsically resistant pathogens, susceptibility to fosfomycin and nitrofurantoin remains sufficient. Therefore, they remain an additional option for empirical treatment of uncomplicated UTI in men.

OBJECTIVES: To determine the influence of a national surveillance system for neonates (NEO-KISS) in neonatal intensive care units (NICUs) on consumption of antibacterial and to identify risk factors for prescriptions. METHODS: Data on antibacterial use between 2013 and 2019 from 231 NICUs in Germany was analyzed in this longitudinal study after introduction of a mandatory module for surveillance of antibacterial consumption in preterm infants. 59,411 newborns with a birth weight under 1500 gs were under surveillance in NEO-KISS during the study period. We report the development of antibacterial consumption during the days of treatment (DOT)/1000 patient days (PD) including the name of the substance administered. Risk factors for antibacterial treatment over time were analyzed. RESULTS: A total, 2,090,341 surveillance patient days were monitored. Antibacterial consumption was 430.4 DOT/1000PD (Median 380.3; IQR: 284.2-502.7). Antibacterial use significantly decreased by 19.5% from 2013, 474.3 DOT/1000PD to 382.1 DOT/1000PD in 2019. Use of penicillins with extended spectrum (J01CA), other aminoglycosides (J01GB), glycopeptide antibacterials (J01XA and J01DH), and third-generation cephalosporins (J01DD) decreased, while use of macrolides (J01FA) and combinations of penicillins, including beta-lactamase inhibitors (J01CR), increased over time. Regression analysis identified year of birth as an independent protective factor for the prescription of antibacterials in general. CONCLUSION: The implementation of a national mandatory surveillance system was associated with a reduction in antibacterial consumption in preterm infants with VLBW. Surveillance of antibacterial use is an integral part of targeting antimicrobial stewardship efforts.

Introduction: Training in hand hygiene for health care workers is essential to reduce hospital-acquired infections. Unfortunately, training in this competency may be perceived as tedious, time-consuming, and expendable. In preceding studies, our working group detected overconfidence effects in the self-assessment of hand hygiene competencies. Overconfidence is the belief of being better than others (overplacement) or being better than tests reveal (overestimation). The belief that members of their profession are better than other professionals is attributable to the clinical tribalism phenomenon. The study aimed to assess the correlation of overconfidence effects on hand hygiene and their association with four motivational dimensions (intrinsic, identified, external, and amotivation) to attend hand hygiene training. Methods: We conducted an open online convenience sampling survey with 103 health care professionals (physicians, nurses, and paramedics) in German, combining previously validated questionnaires for (a) overconfidence in hand hygiene and (b) learning motivation assessments. Statistics included parametric, nonparametric, and cluster analyses. Results: We detected a quadratic, u-shaped correlation between learning motivation and the assessments of one's own and others' competencies. The results of the quadratic regressions with overplacement and its quadratic term as predictors indicated that the model explained 7% of the variance of amotivation (R2 = 0.07; F(2, 100) = 3.94; p = 0.02). Similarly, the quadratic model of clinical tribalism for nurses in comparison to physicians and its quadratic term explained 18% of the variance of amotivation (R2 = 0.18; F(2, 48) = 5.30; p = 0.01). Cluster analysis revealed three distinct groups of participants: (1) "experts" (n1 = 43) with excellent knowledge and justifiable confidence in their proficiencies but still motivated for ongoing training, and (2) "recruitables" (n2 = 43) who are less competent with mild overconfidence and higher motivation to attend training, and (3) "unawares" (n3 = 17) being highly overconfident, incompetent (especially in assessing risks for incorrect and omitted hand hygiene), and lacking motivation for training. Discussion: We were able to show that a highly rated self-assessment, which was justified (confident) or unjustified (overconfident), does not necessarily correlate with a low motivation to learn. However, the expert's learning motivation stayed high. Overconfident persons could be divided into two groups: motivated for training (recruitable) or not (unaware). These findings are consistent with prior studies on overconfidence in medical and non-medical contexts. Regarding the study's limitations (sample size and convenience sampling), our findings indicate a need for further research in the closed populations of health care providers on training motivation in hand hygiene.

BACKGROUND: Increasing antimicrobial resistance is a serious societal challenge affecting outpatient, inpatient and veterinary care. The German One-Health project, RAI (Rational use of Antibiotics via Information and Communication) addresses all three sectors. In the outpatient sector, General Practitioners (GPs) are the main prescribers of antibiotics and were therefore, targeted for this study. A multimodal intervention focusing on Acute Respiratory Tract infections (ARI) was designed and implemented. The aim of this study was to evaluate acceptance, rating and the self-reported impact of the intervention among GPs. METHODS: The intervention offered six tools: a GP training on rational antibiotic use, an app for self-monitoring, a leaflet and a set of posters (both for use as information materials in waiting rooms) and both digital and printed information prescriptions (material for 'prescribing' information instead of an antibiotic to the patient). The tools could be used according to individual preferences. The intervention was conducted between August 2016 and July 2017. Following the intervention, a three pages anonymous questionnaire was sent to all 271 participants. Items covered socio-demographic and professional background, use and judgement of the intervention tools (6 point Likert scale), impact of the intervention tools (4 point Likert scale). RESULTS: The response rate was 39% (n = 107). On average, respondents used 3.1 of the six available tools, with printed information prescriptions used most frequently (79%). Digital information prescriptions were used more frequently by men than by women (OR 2.8; 95% CI 1.16-7.24; p = 0.02). Eighty-seven percent of respondents stated that information prescriptions supported doctor-patient communication. In a comparison of the overall impression of the different intervention tools the GP training on rational antibiotic use was rated best (1.67 on a 6 point scale with 1 = highest, 6 = lowest) and most often noted as having had a "strong" or "very strong" impact on personal antibiotic prescribing behavior. CONCLUSIONS: The multimodal intervention addressing education and communication was well accepted among GPs and could help in fostering rational use of antibiotics in primary care.

Background: The monitoring of antimicrobial resistance (AMR) in microorganisms that circulate in the environment is an important topic of scientific research and contributes to the development of action plans to combat the spread of multidrug-resistant (MDR) bacteria. As a synanthropic vector for multiple pathogens and a reservoir for AMR, flies can be used for surveillance. Methods: We collected 163 flies in the inner city of Berlin and examined them for extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli genotypically and phenotypically. Results: The prevalence of ESBL-producing E. coli in flies was 12.9%. Almost half (47.6%) of the ESBL-positive samples showed a co-resistance to ciprofloxacin. Resistance to carbapenems or colistin was not detected. The predominant ESBL-type was CTX-M-1, which is associated with wildlife, livestock, and companion animals as a potential major source of transmission of MDR E. coli to flies. Conclusions: This field study confirms the permanent presence of ESBL-producing E. coli in an urban fly population. For continuous monitoring of environmental contamination with multidrug-resistant (MDR) bacteria, flies can be used as indicators without much effort.

Background: Bloodstream infections (BSI) are among the most frequently documented healthcare-associated infections (HAI). Central and peripheral venous catheters (CVC and PVC) are relevant risk factors for BSI. Although the risk for BSI is higher for CVC, PVC are utilized more frequently and are therefore relevant in the context of HAI prevention. Robust data on the prevalence of PVC and associated infections in German hospitals are scarce to this date. The objectives of this survey were to estimate the prevalence of PVC and PVC-associated infections on peripheral wards of a large tertiary care hospital in Germany. The collected data may be utilized for a tailored infection prevention intervention in the future. Methods: A point prevalence survey was conducted on peripheral wards of a tertiary care hospital with more than 3.000 beds. Data were collected between August 2017 and February 2018. Standardized data collection forms were used for collecting ward, patient and PVC-related data. As endpoints, prevalence of patients with PVC, PVC-associated infections and PVC without usage in the 24 h prior to the survey and without documentation of intended usage in the 24 h after the survey ("unused PVC") were chosen. For data analysis, Kruskal-Wallis test was employed for continuous variables and Chi-squared test or Fisher's exact test for categorical variables. Multivariable analysis and logistic regression were performed for the endpoint unused PVC. Results: Data from 2.092 patients on 110 wards were collected. The overall prevalence of patients with PVC was 33%. Infections were recorded in 16 patients. Except one case of BSI, these were all local infections at the site of insertion. Of 725 documented PVC, 77 (11%) were unused PVC. Multivariate analysis and logistic regression revealed wards with the practice of regularly obtaining blood from PVC, PVC with dirty or loose insertion dressing, pediatric ward specialty and last inspection of the PVC more than 1 day ago as significant risk factors for unused PVC. Conclusions: A substantial proportion of patients presented with a PVC on the day of survey. Too few infections were recorded to allow for more detailed analyses. Various risk factors for unused PVC were identified. We hereby present a solid method to obtain an overview about PVC use and to increase awareness for PVC-associated risks. The limitations of point prevalence surveys have to be recognized.

Background: Blood cultures (BCs) are the gold standard for diagnosing sepsis and are prerequisite for a targeted antibiotic treatment and essential for patient outcomes. Aim of the study was to analyze the frequency of BCs, the rate of central line-associated bloodstream infections (CLABSIs) and to study the association between both parameters on intensive care units in Germany over time. Methods: Cross-sectional studies at two points in time (2006, 2015) on ICUs participating in the German hospital infection surveillance system. CLABSIs were defined according to the Center for Disease Control and Prevention (CDC). Univariable and multivariable analyses were performed using generalized linear models. Results: A total of 639 ICUs participated in 2006 or 2015 and 90 ICUs ("core group") in both years. Overall, 2,427,921 patient days from 644,575 patients were analyzed. In the ICU core group the frequency of BCs per 1000 patient days doubled from 57.8 (interquartile range [IQR] 29.8-101.2; 2006) to 128.2 (IQR 71.6-183.2; 2015). In the same time, the pooled median CLABSI rate decreased from 0.8 (IQR 0-1.9; 2006) per 1000 central-line catheter days to 0.2 (IQR 0-0.9; 2015). Conclusions: From 2006 to 2015 the frequency of BCs increased on ICUs in Germany and is now within the recommended 100 to 200 BCs sets per 1000 patient days.

BACKGROUND: This study investigates the barriers and facilitators of the use of antibiotics in acute respiratory tract infections by general practitioners (GPs) in Germany. METHODS: A multidisciplinary team designed and pre-tested a written questionnaire addressing the topics awareness of antimicrobial resistance (7 items), use of antibiotics (9 items), guidelines/sources of information (9 items) and sociodemographic factors (7 items), using a five-point-Likert-scale ("never" to "very often"). The questionnaire was mailed by postally to 987 GPs with registered practices in eastern Germany in May 2015. RESULTS: 34% (340/987) of the GPs responded to this survey. Most of the participants assumed a multifactorial origin for the rise of multidrug resistant organisms. In addition, 70.2% (239/340) believed that their own prescribing behavior influenced the drug-resistance situation in their area. GPs with longer work experience (> 25 years) assumed less individual influence on drug resistance than their colleagues with less than 7 years experience as practicing physicians (Odds Ratio [OR] 0.32, 95% Confidence Interval [CI] 0.17-0.62; P < 0.001). 99.1% (337/340) of participants were familiar with the "delayed prescription" strategy to reduce antibiotic prescriptions. However, only 29.4% (74/340) answered that they apply it "often" or "very often". GPs working in rural areas were less likely than those working in urban areas to apply delayed prescription. CONCLUSION: The knowledge on factors causing antimicrobial resistance in bacteria is good among GPs in eastern Germany. However measures to improve rational prescription are not widely implemented yet. Further efforts have to be made in order to improve rational prescription of antibiotic among GPs. Nevertheless, there is a strong awareness of antimicrobial resistance among the participating GPs.

Background: Drivers of antibiotic (AB) resistance (ABR) include outpatient treatment, hospital care and animal husbandry. During the first phase of the One Health project RAI (Responsible Antibiotic Use via Information and Communication) surveys were conducted in these sectors. Objectives: To compare perceptions and attitudes towards ABR among general practitioners (GPs), hospital physicians, veterinarians, pig farmers and the general public. Methods: Cross-sectional questions on AB use and ABR were integrated in group-specific surveys of GPs, hospital physicians, veterinarians, pig farmers and the German general population. Results: A total of 1789 participants (340 GPs, 170 hospital physicians, 215 pig farmers, 60 veterinarians and 1004 members of the public) responded. Each group tended to identify drivers of ABR as being from outside its own area of activity. Guidelines were shown to be an important information source for AB therapy for all prescriber groups, but the frequency of routine use differed (39% of GPs, 65% of hospital physicians and 53% of veterinarians). Regarding further information sources, hospital physicians preferred smartphone apps and e-learning, GPs preferred non-sponsored training and veterinarians preferred multidisciplinary networks and e-learning. Farmers were predominantly satisfied with existing solutions. Farmers had three times better basic knowledge of ABR and knew twice as many people with MDR organism problems than the general public. They also received information on ABR more often from their veterinarians than patients did from their doctors. Conclusions: This study reveals considerable differences in perceptions and attitudes to ABR among the groups investigated. The results can help to tailor future interventions. Furthermore, they promote mutual understanding and thus support the One Health approach.

OBJECTIVES: Knowledge concerning antibiotic use in the general population is insufficient. The way health literacy is related to antibiotic use aside from knowledge needs further investigation. Our aim was to compare the levels of knowledge of antibiotics and health literacy in individuals who had taken antibiotics in recent years compared with those who not had taken antibiotics. METHODS: A population-based cross-sectional survey of 2,000 individuals aged 35 and older from Berlin, Germany and its surrounding rural and suburban areas (response rate 59%) with strata urban/rural, sex, age, and education. Computer-assisted personal interviews were conducted by external, trained interviewers during home visits. Knowledge, health literacy, and antibiotic use were assessed using standardized questionnaires. RESULTS: In all, 33.3% (666/2,000) of the participants indicated having had an antimicrobial therapy during the previous 12 months. Adjusting for sex, age, educational level and health literacy, individuals with four correct answers regarding antibiotics were 1.70 times and those with three correct answers 1.94 more likely to have had a history of recent antibiotic use than those who did not have any correct answers. Individuals with sufficient health literacy were 0.57 times less likely to have had a recent history of antibiotic use than individuals with insufficient health literacy. CONCLUSION: Patients who have used antibiotics might have more knowledge as a result of their recent involvement with the topic of antibiotic use; health literacy may be a preventive mechanism to use antibiotics more critically. Besides improving the health knowledge of the general population and of vulnerable groups such as patients with low levels of health literacy, intervention strategies should focus on providers as well.

BACKGROUND: The influence of the hospital's infrastructure on healthcare-associated colonization and infection rates has thus far infrequently been examined. In this review we examine whether healthcare facility design is a contributing factor to multifaceted infection control strategies. METHODS: We searched PubMed/MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) from 1990 to December 31st, 2015, with language restriction to English, Spanish, German and French. RESULTS: We identified three studies investigating accessibility of the location of the antiseptic hand rub dispenser. Each of them showed a significant improvement of hand hygiene compliance or agent consumption with the implementation of accessible dispensers near the patient bed. Nine eligible studies evaluated the impact of single-patient rooms on the acquisition of healthcare-associated colonization and infections in comparison to multi-bedrooms or an open ward design. Six of these studies showed a significant benefit of single-patient bedrooms in reducing the healthcare-associated colonization and infection rate, whereas three studies found that single-patient rooms are neither a protective nor risk factor. In meta-analyses, the overall risk ratio for acquisition of healthcare-associated colonization and infection was 0.55 (95% CI: 0.41 to 0.74), for healthcare-associated colonization 0.52 (95% CI: 0.32 to 0.85) and for bacteremia 0.64 (95% CI: 0.53 to 0.76), all in favor of patient care in single-patient bedrooms. CONCLUSION: Implementation of single-patient rooms and easily accessible hand rub dispensers located near the patient's bed are beneficial for infection control and are useful parts of a multifaceted strategy for reducing healthcare-associated colonization and infections.
RESUMEN
BACKGROUND: We report on an outbreak in a surgical, interdisciplinary intensive care unit (ICU) of a tertiary care hospital. We detected a cluster of ICU patients colonized or infected with multidrug-resistant Pseudomonas aeruginosa. We established an outbreak investigation team, performed an exploratory epidemiological analysis and initiated an epidemiology-based intervention. METHODS: As part of the outbreak investigation, we performed microbiological examinations of the sinks in the patient rooms and a retrospective case-control study. All patients admitted to the outbreak ICU between January 2012 and February 2014 were included. Cases were patients colonized with the outbreak strain. Controls were patients with a different Pseudomonas aeruginosa strain. Risk factors were evaluated using multivariable conditional logistic regression analysis. Strain typing was performed using the repetitive element-based polymerase chain reaction (rep-PCR) DiversiLab system. RESULTS: The outbreak strain was found in the sinks of five (of 16) patient rooms. Altogether 21 cases and 21 (randomly selected) controls were included. In the univariate analysis, there was no significant difference in baseline data of the patients. In the multivariate analysis, stay in a room with a colonized sink (Odds Ratio[OR] 11.2, p = 0.007) and hemofiltration (OR 21.9, p = 0.020) were independently associated with an elevated risk for colonization or infection by the outbreak strain. In a subsequent evaluation of the work procedures associated with hemofiltration, we found that the ultra-filtrate bags had been on average five times per day emptied in the sinks of the patient rooms and were used multiple for the same patient. We exchanged the traps of the contaminated sinks and eliminated work procedures involving sinks in patient rooms by implementation of single use bags, which are emptied outside patient rooms to reduce splash water at the sinks. In the 20 month follow-up period, the outbreak strain was detected only once, which indicated that the outbreak had been ceased (incidence 0.75% vs. 0.04%, p < 0.001) Furthermore, the incidence of Pseudonomas aeruginosa overall was significantly decreased (2.5% vs. 1.5%, p < 0.001). CONCLUSION: In ICUs, limiting work processes involving sinks results in reduced multidrug-resistant Pseudomonas aeruginosa rates. ICUs with high rates of Pseudomonas aeruginosa should consider eliminating work processes that involve sinks and potentially splash water in close proximity to patients. TRIAL REGISTRATION: All data were surveillance based data which were obtained within the German Law on Protection against Infection ("Infektionsschutzgesetz"). Therefore a trial registration was not required.
RESUMEN
BACKGROUND: The network project RAI (Rational Use of Antibiotics via Information and Communication) is aimed at developing tailored information and communication tools on the subject of antibiotic (AB) resistance for various stakeholder groups. During the preparation phase, a survey was performed addressing the German general population. OBJECTIVES: To gain insights into the knowledge, attitudes, and behavior of nonprescribers concerning AB and multidrug-resistant organisms (MDRO). METHODS: Using computer-assisted, telephone-based interviews a random sample of 1,004 persons aged 14 years and older was surveyed. Descriptive reporting of data and multivariate analysis were performed, including sociodemographic variables. RESULTS: Only 24 % of participants knew that bacteria (but not viruses or humans) could develop AB resistance. However, this knowledge did not influence the outcome of other questions. Regardless of knowledge, 71 % thought that the subject was important, but 58 % did not believe in the influence of their own behavior on MDRO development. When visiting a physician, patients were given an antibiotic three times as often as information on AB resistance. 17 % did not take the AB as prescribed and 20 % of all participants stated that they personally knew at least one person with MDRO problems. This personal involvement had a significant effect on the rating of self-influence, on the importance of the subject, on the interaction between patient and physician (more information, less AB), and on AB intake compliance (less frequent). DISCUSSION: We found considerable knowledge gaps, but this had no impact on the assessment of the subject. A starting point for an intervention could be patient-physician communication. This seems more effective and safer than a public campaign.

OBJECTIVE To improve the patient safety of very-low-birthweight infants in neonatal departments in Germany. DESIGN Multicenter cohort study with a baseline (24 months), an intervention (12 months), and a postinterventional follow-up period (12 months) and time series analysis. STUDY POPULATION Very-low-birthweight patients from 32 neonatal departments in Germany. METHODS Neonatal departments showing a standardized infection ratio of bloodstream infection 10% higher than the expected number (standardized infection ratio ≥1.1) were invited to participate in the study. To reduce the occurrence of primary bloodstream infections, evidence-based bundles to improve catheter maintenance routines, insertion practice, and hand-hygiene compliance were implemented in the participating infirmaries. RESULTS Thirty-four departments participated in the study and 32 reported data. In total, 6,222 very-low-birthweight infants with 231,868 patient-days and 1,405 cases of bloodstream infections were analyzed. In the baseline period the pooled mean bloodstream infection rate was 6.63 (95% CI, 6.17-7.12) per 1,000 patient-days. The bloodstream infection rate decreased in the intervention period to 5.68 (relative risk, 0.86 [95% CI, 0.76-0.97]) and in the 1-year follow-up period to 5.31 per 1,000 patient-days (relative risk, 0.80 [95% CI, 0.70-0.92]). The multivariable time series analysis of monthly aggregated data showed a significant change in the slope for the frequency of bloodstream infections from the start to the end of the intervention (change in slope incidence rate ratio, 0.97; P=.001). CONCLUSION The implementation of an intervention bundle is feasible and can reduce bloodstream infections in neonatal departments. Infect Control Hosp Epidemiol 2016;37:798-804.

In western countries, negative illness perceptions are associated with poor health status and affect health outcomes in primary care populations. The aim of this study is to examine the relationship between illness perception and mental and physical health status in general hospital outpatients in China. This multicentre, cross-sectional study analysed a total of 281 consecutive patients from four general hospital outpatient departments of internal medicine and traditional Chinese medicine in Beijing and Kunming. The patients answered questionnaires concerning illness perception (Brief-IPQ), somatic symptom severity (Patient Health Questionnaire-15), illness behaviour (Scale for the Assessment of Illness Behaviour), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (Twelve-Item Short Form Health Survey). Negative illness perception, especially negative emotional reactions, perceived illness consequences, encumbering illness concerns, and strong illness identity were significantly associated with high emotional distress, impairing illness consequences, and a low mental and physical quality of life. Using a multiple linear regression model, five strongest correlates of negative illness perception were high anxiety, seeking diagnosis verification, low mental and physical quality of life and high somatic symptom severity. The variance explained by this model was 35%. Chinese general hospital outpatients showed associations between negative illness perceptions and poor mental and physical health status that were similar to those of primary care patients in western countries. The main difference was that no association with perceived illness control was found in Chinese patients. Chinese physicians should be sensitised to their patients' negative illness perceptions and should focus on helping patients cope with uncertainty and anxiety by providing an understandable illness model and increasing control beliefs.

OBJECTIVE: In high-income countries, the number and severity of somatic symptoms - irrespective of etiology--are associated with adverse psychobehavioral and functional characteristics. This study aimed to assess these key features among Chinese general hospital outpatients with high levels of somatic symptoms. METHODS: This multicenter, cross-sectional study evaluated four outpatient departments of internal medicine and Traditional Chinese Medicine in Beijing and Kunming and enrolled a total of 281 consecutive patients. The patients answered questionnaires concerning somatic symptom severity [Patient Health Questionnaire (PHQ-15)], illness perception (Brief Illness Perception Questionnaire), illness behavior (Scale for the Assessment of Illness Behavior), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (12-Item Short Form Health Survey). Subsamples reporting high scores of somatic symptom severity (PHQ-15 ≥10, SOM+) versus low scores (PHQ-15 <10, SOM-) were compared. RESULTS: Twenty-eight percent (79/281) of all outpatients showed high somatic symptom severity. The strongest correlations between high somatic symptom severity and psychobehavioral variables were found for high emotional distress, female gender, living alone, low physical quality of life and high dysfunctional illness behavior. The proportion of the explained variance was 36.1%. CONCLUSION: In Chinese outpatients, high somatic symptom severity is frequent and associated with psychobehavioral characteristics. With the PHQ-15 cutoff of 10, SOM+ patients could be differentiated from SOM- patients using these characteristics.
