Use of antibiotics in long-term care facilities for the elderly in Germany - point prevalence as a possible first step for data-based antibiotic stewardship.

Introduction: In Germany, hospitals, rehabilitation facilities and outpatient surgery facilities are required by law to perform antibiotic-consumption surveillance. Established IT programs are available for recording the defined daily doses. These do not exist for long-term care facilities (LTCFs). Antibiotic stewardship is also recommended for LTCFs. In view of the lack of IT solutions for consumption surveillance, this study investigated whether point prevalence studies could be a suitable basis for a data-based antibiotic stewardship program in LTCFs. Method: In May 2023, 18 elderly-care facilities in Berlin, Germany, participated in a point prevalence survey on antibiotic consumption according to the established HALT (healthcare-associated infections in long-term care facilities) method. The number of residents present and their risk factors (including the use of catheters and antibiotic therapy) were recorded. The results were compared with comparable data from previous surveys in LTCFs in Berlin, Germany as well as with the HALT data for Europe as a whole and for Germany. Results: On the day of the survey, 2040 residents were present, 7.7% of whom bore a urinary catheter and 0.5% a vascular catheter. 0.2% of the residents had a port access, 0.4% a dialysis catheter and one resident (0.05%) a tracheostoma. Twenty-seven (1.3%) residents were receiving an antibiotic on the day of the survey. Of these, 29.6% had a urinary tract catheter. 63.0% of the antibiotics were given for a urinary tract infection, 14.8% for a respiratory tract infection and 11.1% for a wound/soft tissue infection. The overall prevalence of antibiotics was in the range of previous surveys from Germany (1.2-2.4%) and significantly lower than in the Europe-wide HALT survey overall (4.3-4.5%). Discussion: The survey showed low use of antibiotics in the LTCFs in comparison with Europe-wide surveys. The time required was less than 2 hours for a 100-bed facility. Until appropriate IT programs to determine the defined daily doses are also available for LTCFs, such easy-to-perform and standardized point-prevalence surveys - if repeated several times a year - can be a suitable method for recording the use of antibiotics in nursing homes for the elderly.

Heat-related mortality in Frankfurt am Main, Germany, from 2000 to 2023.

Background: The major heatwave in Europe in August 2003 resulted in 70,000 excess deaths. In Frankfurt am Main, a city with 767,000 inhabitants in the south-west of Germany, around 200 more people died in August 2003 than expected. Soon afterwards, the city introduced adaptation measures to prevent heat-related health problems and subsequently established further mitigation measures to limit climate change. Frankfurt is rated as being one of the cities in Germany to have implemented the best climate adaptation and mitigation measures. This study addressed the following questions: is there already a downward trend in mortality from heat and can this be attributed to the measures taken? Materials and methods: The age-standardized mortality rate (ASR) was calculated for the months of June to August and for calendar weeks 23 to 34 of the individual years on the basis of population data and deaths of the inhabitants of Frankfurt am Main for the years 2000 to 2023. This was related to the meteorological data from the Frankfurt measuring station of the German National Meteorological Service. For four different heat exposure indicators (heat days, days in heat weeks, days in heatwaves and days with heat warnings), the incidence rate (death cases per 1 million person days) (IR) was calculated for days with and without exposure, and the incidence rate difference and the incidence rate ratio (IRR) were estimated to compare days with vs days without exposure. Results: Over the years, the mean daily temperatures tended to increase, and the standardized mortality rate decreased. An increase in ASR was observed during heatwaves up to 2015, but no longer in the later ones. In the summer of 2003, the incidence rate was 16.0 (95% confidence interval (CI) 12.2-19.9) per 1 million person days greater on heat days than on days not classified as heat days, and the corresponding incidence rate ratio was 1.64 (95% CI 1.48-1.82). Although the weather data for the summers of 2018 and 2022 were comparable with the record-breaking heat summer of 2003, the incidence rate differences (2018: 3.8, 95% CI 0.9-6.7; 2022: 2.3, 95% CI -0.3-4.9) and the IRR (2018: 1.20, 95% CI 1.05-1.37; 2022: 1.12, 95% CI 0.99-1.26) were considerably lower. Similar results were also obtained when comparing mortality in heat weeks and heatwaves as well as on days with heat warnings. Discussion: In summary, our study in Frankfurt am Main not only showed a decrease in heat-related mortality in the population as a whole over the years, but also a decrease in excess mortality during various heat periods (day, week, wave, warning), especially in comparison with the years with very high heat stress and drought (2003, 2018 and 2022). However, whether this development represents success of the intensive prevention measures that have been implemented in the city for years or merely describes a general trend cannot be answered with certainty by the present study. To answer this question, a comparative study should be carried out in various municipalities in the Rhine-Main region with different levels of intensity in dealing with the heat problem.

The new reporting obligation for Respiratory Syncytial Virus (RSV) in Germany - a critical view.

Background: In summer 2023, mandatory reporting of respiratory syncytial virus (RSV) by name was introduced in Germany. The stated objectives were: to improve the database to prevent overburdening of the healthcare system, to implement targeted, early investigation and action by local health authorities to prevent further spread, and to assess vaccines after the expected approval of RSV vaccination. Methods: These objectives are examined against the background of data from mandatory reporting of RSV in the German federal state of Saxony, which has been required since 2002, and the data from the ARE (acute respiratory diseases) survey in Germany, considering the basic legal requirements and options of the Infection Protection Act, the requirements of the EU Commission for the collection of data on infectious diseases and the recommendations by experts of the European Centre for Disease Prevention and Control (ECDC), the options for individual or general preventive measures by the health authorities and previous experience with the evaluation options of the reported data (especially regarding the effectiveness of vaccinations). Results and discussion: An extrapolation of the previously reported data from Saxony to the whole of Germany shows that over 100,000 reports per year must be expected (more than the reports of both rota and noroviruses together). Neither the requirements of the EU Commission nor the views of an expert group of the ECDC recommend mandatory RSV reporting. Mandatory reporting by name is also not appropriate from a legal perspective. A sentinel, which is also better suited to assessing vaccinations, would be more appropriate to avoid unnecessarily overburdening the health authorities. In addition, initial experience with wastewater sentinels for RSV has shown that they may be used to record local and regional RSV infections - albeit without information on the severity of the disease and thus the burden on the healthcare system.Against this background, mandatory reporting of RSV does not appear to be appropriate. Instead, the existing sentinels should be continued and further expanded, possibly supplemented by RSV wastewater monitoring.

Rescue service deployment data as an indicator of heat morbidity in Frankfurt / Main, Germany (2014-2022) - Trend association with various heat exposure indicators and considerations for outreach.

Many publications dealt with the monitoring of heat-related mortality. Fewer analyses referred to indicators of heat-related morbidity. The aim of this work was to describe the heat-related morbidity using rescue service data from the city of Frankfurt/Main, Germany for the time period 2014-2022, with regard to the questions: 1) How do rescue service deployments develop over the years? Is there a trend identifiable towards a decrease in deployments over the years, e.g. as an effect of either (physiological) adaptation of the population or of the measures for prevention of heat-related morbidity? 2) Which heat parameters (days with a heat warning, heat days, heat weeks, heat waves) are most strongly associated with heat-related morbidity in terms of rescue service deployments and might therefore be additionally used as an easily communicable and understandable heat-warning indicator? Rescue service data were provided by the interdisciplinary medical supply compass system "IVENA" and adjusted for population development including age development. The effect of various indicators for heat exposure, such as days with a heat warning from the German meteorological service based on the scientific concept of "perceived heat", heat days, heat wave days and heat week days on different endpoints for heat morbidity (deployments in total as well as for heat associated diagnoses) was calculated using both difference-based (difference ± 95% CI) and ratio-based (ratio ± 95% CI) effect estimators. Rescue services deployments in summer months increased overall from 2014 to 2022 in all age groups over the years (2698 to 3517/100.000 population). However, there was a significant decrease in 2020, which could be explained by the special situation of the COVID-19 pandemic, probably caused by the absence of tourists and commuters from the city. In addition, no data are available on the actual implementation of the measures by the population. Therefore, an effect of the measures taken to prevent heat-associated morbidity in Frankfurt am Main could not be directly demonstrated, and our first question cannot be answered on the basis of these data. Almost all heat definitions used for exposure (day with a heat warning, heat day, heat wave day, heat week day) showed significant effects on heat-associated diagnoses in every year. When analysing the effect on all deployments, the effect was in part strongly dependent on individual years: Heat wave days and heat week days even showed negative effects in some years. The definition heat day led to a significant increase in rescue service deployments in all single years between 2014 and 2022 (ratio 2014-2022 1.09 (95CI 1.07-1.11); with a range of 1.05 (95CI 1.01-1.09) in 2020 and 1.14 (95CI 1.08-1.21) in 2014), this was not the case for days with a heat warning (ratio 2014-2022 1.04 (95CI1.02-1.05); with a range of 1.01 (95CI 0.97-1.05) in 2017 and 1.16 (95CI 1.10-1.23). Thus being not inferior to the heat warning day, the "heat day" defined as ≥32 °C maximum temperature, easily obtainable from the weather forecast, can be recommended for the activities of the public health authorities (warning, surveillance etc.) regarding heat health action planning.

Excess mortality during the SARS-CoV-2 pandemic in the City of Frankfurt/Main, Germany, in 2020 and 2021, adjusted for age trends and pandemic phases.

Aims: Excess mortality during the SARS-CoV-2 pandemic has been studied in many countries. Accounting for population aging has important implications for excess mortality estimates. We show the importance of adjustment for age trends in a small-scale mortality analysis as well as the importance of analysing different pandemic phases for mortality in an urban population. Methods: Population data for Frankfurt/Main for 2016-2021 were obtained from the Municipal Office of Statistics, City of Frankfurt/Main. Mortality data from 2016 to 2021 were provided by the Hessian State Authority. For standardized mortality ratios (SMR=observed number of deaths divided by the expected number of deaths), the expected number of deaths was calculated in two ways: For SMRcrude, the mean mortality rate from the years 2016-2019 was multiplied by the total number of residents in 2020 and 2021 separately. For SMRadjusted, this procedure was performed separately for five age groups, and the numbers of expected deaths per age group were added. Results: SMRcrude was 1.006 (95% CI: 0.980-1.031) in 2020, and 1.047 (95% CI: 1.021-1.073) in 2021. SMRadjusted was 0.976 (95% CI: 0.951-1.001) in 2020 and 0.998 (95% CI: 0.973-1.023) in 2021. Excess mortality was observed during pandemic wave 2, but not during pandemic waves 1 and 3. Conclusion: Taking the aging of the population into account, no excess mortality was observed in Frankfurt/Main in 2020 and 2021. Without adjusting for population aging trends in Frankfurt /Main, mortality would have been greatly overestimated.

Development of morbidity and mortality of SARS-CoV-2 in nursing homes for the elderly in Frankfurt am Main, Germany, 2020-2022: What protective measures are still required?

Introduction: Nursing-home residents are among the highest risk group in the SARS-CoV-2 pandemic. At the onset of the SARS-CoV-2 pandemic, the majority of all deaths from or with SARS-CoV-2 occurred in long-term care facilities (LTCFs), so that maximum protective measures were mandated for these facilities. This study analyzed the impact of the new virus variants and the vaccination campaign on disease severity and mortality among nursing home residents and staff through 2022 as a basis for determining which protective measures remain necessary and appropriate. Methods: In five homes in Frankfurt am Main, Germany, with a total capacity for 705 residents, all cases occurring in the facility among residents and staff were recorded and documented (date of birth and diagnosis, hospitalization and death, vaccination status) and were descriptively analyzed with SPSS. Results: By 31st August 2022, 496 residents tested positive for SARS-CoV-2, 93 in 2020, 136 in 2021, and 267 in 2022; 14 residents presented with a second SARS-CoV-2 infection in 2022, having previously experienced an infection in 2020 or 2021. The percentage of hospitalizations decreased from 24.7% (2020) and 17.6% (2021) to 7.5% (2022), and the percentage of deaths decreased from 20.4% and 19.1% to 1.5%. In 2021, 61.8% of those infected were vaccinated (at least 2x); in 2022, 86.2% of residents had been vaccinated twice, 84% of whom had already had a booster vaccination. Hospitalization and death rates were significantly higher among the unvaccinated than the vaccinated throughout all years (unvaccinated 21.5% and 18.0%; vaccinated 9.8% and 5.5%; KW test p=0.000). However, this difference was no longer significant under the prevalence of the Omicron variant in 2022 (unvaccinated 8.3% and 0%; p=0.561; vaccinated 7.4% and 1.7%; p=0.604). From 2020 to 2022, 400 employees were documented as infected, with 25 having second infections in 2022. Only one employee showed a second infection in 2021 following the first in 2020. Three employees were hospitalized; no deaths occurred. Discussion and conclusion: Severe COVID-19 courses occurred with the Wuhan Wild type in 2020, with a high death rate among nursing-home residents. In contrast, during the waves in 2022 with the relatively mildly pathogenic Omicron variant, many infections but few severe courses and deaths were observed among the now mostly vaccinated and boostered nursing-home residents. Given the high immunity of the population and the low pathogenicity of the circulating virus - even in nursing-home residents - protective measures in nursing homes that restrict people's right to self-determination and quality of life no longer seem justified. Instead, the general hygiene rules and the recommendations of the KRINKO (German Commission for Hospital Hygiene and Infection Prevention) on infection prevention should be followed, and the recommendations of the STIKO (German Standing Commission on Vaccination) on vaccination not only against SARS-CoV-2 but also against influenza and pneumococci should be observed.

[The SARS-CoV-2 Pandemic in Long-Term Care Facilities for the Elderly: Analysis of Data from Frankfurt am Main, Germany, March 2020 - September 2021]. / Die SARS-CoV-2-Pandemie in Altenpflegeheimen: Erkenntnisse und Analysen in Frankfurt am Main von März 2020 bis September 2021.

BACKGROUND: Residents in long-term care facilities (LTCF) are particularly vulnerable during the SARS-CoV-2 pandemic. In the first wave of the pandemic in many countries, 30-70% of all deaths from or with SARS-CoV-2 were LTCF residents, although their proportion in the population is typically less than 1%. Findings from LTCFs in Frankfurt am Main (March 2020-September 2021) are presented below and discussed in terms of necessary improvements. MATERIAL AND METHODS: The reports of positive PCR tests for SARS-CoV-2 in residents and staff of the LTCF in Frankfurt am Main and their symptoms were descriptively evaluated. In addition, the total deaths in nursing homes from 2018 to June 2021 were surveyed per quarter. RESULTS: In the first pandemic wave (March-May 2020), 111 SARS-CoV-2-positive LTCF residents were reported to the Public Health Department in Frankfurt am Main, of whom 40% were asymptomatic, 48% were hospitalized, and 23% died. In the subsequent pandemic phases through September 30, 2021, additional 1196 residents infected with SARS-CoV-2 were reported, with most of them being asymptomatic (70%); they were hospitalized less frequently (27%). Mortality was also lower (17.6%). Overall mortality in LTCF was 7.6% higher in 2020 than in 2019 and 1.1% higher than in the "flu year" of 2018. DISCUSSION: In contrast to the first wave, when only a few LTCF residents contracted COVID-19, in the second pandemic wave in autumn/winter 2020/21, with high incidences in the general population, SARS-CoV-2 outbreaks in LTCF in Frankfurt could not be prevented, despite extensive hygiene, infection prevention, and contact mitigation measures (including visitor restrictions) that massively limited residents' quality of life and their personal rights. Only when vaccination rates increased among residents and staff from April 2021 onwards, there were no massive outbreaks. To better protect LTCF residents, an appropriate balance was called for between protecting against infection and avoiding collateral damage by maintaining the freedom and quality of life of nursing home residents as best as possible.

[Legal Obligation to Notify Severe Clostridiodes difficile Infections - Data from Frankfurt am Main, Germany. Overview and Discussion]. / Meldepflicht für schwere Clostridiodes difficile ­ Infektionen ­ Daten aus Frankfurt am Main, 2014­2018. Bestandsaufnahme und Diskussion.

BACKGROUND: Clostridioides difficile (C. difficile) is the most frequently identified causative agent of antibiotic-associated diarrhea in industrialized countries. As early as 2007, severe C. difficile infections (CDI) were to be notified in Germany as a "threatening disease with an indication of grave danger to the general public". In 2016, the Notification Adjustment Ordinance put in force a duty to notify CDI with a clinically severe course. Here, the necessity and suitability of mandatory notification of severe CDI in Frankfurt am Main, Germany, 2014-2018 is examined. MATERIAL/METHOD: Cases of CDI reported to the health department Frankfurt am Main were compared with the C. difficile-associated deaths in Frankfurt for 2014-2018. The results were compared with data from the literature, the national reporting data according to the Infection Protection Act (IfSG), the mortality statistics, the hospital treatment data as well as the hospital surveillance data of the German hospital infection surveillance system for C difficile-associated diarrhea (CDAD). RESULTS: With the entry into force of the new Notification Adjustment Ordinance, the number of CDIs reported annually in Frankfurt am Main increased from 5-8 to 13-14; however, in all years (with the exception of 2016), the number of deaths (death-leading illness or previous cause) was -17-50 per year and thus well above the number of reported CDI-cases according to the German Infection Protection Act. CONCLUSION: The notification data from Frankfurt am Main show an approx. 2-fold lower score compared to the CDI-associated deaths. From the data of the Hospital Surveillance System (CDAD-KISS), it can be estimated that the majority of the cases are not notified. While an increase in CDI notifications is reported nationwide, there is a decrease in data from nationwide death statistics, hospital treatment data and CDI prevalence, and an increase in incidence of severe CDI. Therefore, and taking into account legal requirements of the IfSG and the options for action of the health authorities according to § 23 (4) Infection prevention act (IfSG), and regarding European recommendations and available data on CDI surveillance, the obligation to notify CDI should be lifted.

A European approach to infection prevention and control goals.

The current pandemic caused by COVID-19 has underlined the importance of a joint effort and approach to ensure patient and health care worker safety in medical care throughout Europe. In addition, the recent flood disasters in Germany and other countries called for immediate joint action, in this case with regard to the prevention of water-borne infections. Environmental disasters will increase with consequences for hospitals and nursing homes. Cooperative efforts are needed for preventing and controlling associated infection outbreaks, new pathogens will appear and a geographic shift of infectious diseases previously not detected in certain areas has already been observed. This approach to infection prevention and control must entail structural as well as regulatory aspects. The principle of equal protection against infections in all European countries must be implemented. Prevention and control of infections, including nosocomial infections, infections caused by antibiotic-resistant bacteria as well as pandemics, need to be based on equal standards in all of Europe. Protection against infections and other public health risks in all European countries is the best guarantor for building trust and identification of citizens in our common Europe. Experts in the fields of hygiene, microbiology, infectiology and epidemiology have to pool the expertise on the prevention and control of infections from different European countries and define key targets for achieving a high standard of hygiene measures throughout Europe. The participants of the Rudolf Schülke Foundation International Symposium call for immediate action and priority to be given to the realization of the proposed 16-point plan.

[Children in the COVID-19 pandemic and the public health service (ÖGD) : Data and reflections from Frankfurt am Main, Germany]. / Kinder in der COVID-19 Pandemie und der Öffentliche Gesundheitsdienst (ÖGD) : Daten und Überlegungen aus Frankfurt am Main.

BACKGROUND: The measures taken to combat the COVID-19 pandemic have severely restricted the opportunities for the development of children. This paper will discuss the reporting data of children and the public health department's activities against the background of the restrictions of school and leisure time offers as well as sports and club activities. MATERIALS AND METHODS: Reporting data from Frankfurt am Main, Hesse, were obtained using a SURVStat query for the calendar weeks 10/2020-28/2021 and from SURVNet (until 30 June 2021). Contact persons (CP) of SARS-CoV­2 positive persons from schools and daycare centers were screened for SARS-CoV­2 by PCR test. These results and those of rapid antigen testing, which has been mandatory for schoolchildren since April 2021, are presented. RESULTS: Until Easter break, the age-related seven-day incidence values per 100,000 for children 14 years of age and younger were lower than the overall incidence; it was only higher after rapid antigen-testing was mandatory for schoolchildren. Most children with SARS-CoV­2 had no or mild symptoms; hospitalization was rarely required and no deaths occurred. Contact tracing in schools and daycare centers found no positive contacts in most cases and rarely more than two. Larger outbreaks did not occur. CONCLUSION: SARS-CoV­2 infections in children appear to be less frequent and much less severe than in adults. Hygiene rules and contact management have proven themselves effective during times with high incidences in the local population without mandatory rapid antigen testing - and even with a high proportion of variants of concern (alpha and delta variants) in Germany. Against this background, further restriction of school and daycare operations appears neither necessary nor appropriate.

Changing epidemiology of vancomycin-resistant Enterococcus faecium: Results of a genome-based study at a regional neurological acute hospital with intensive care and early rehabilitation treatment.

BACKGROUND: Vancomycin-resistant Enterococcus faecium (VREfm) are an emerging threat worldwide. In Germany, a VRE-belt with higher VREfm prevalences transversing its central east-west axis and including the state of Hesse was previously described. Recently, we detected a predominant VREfm clone in hospitals throughout the Rhine-Main metropolitan area of Hesse. AIM: Here we expanded our study on VREfm to a regional neurological acute hospital outside of the metropolitan area with patient referrals from throughout Hesse and the neighboring federal state of Rhineland-Palatinate. MATERIAL/METHODS: VREfm isolates obtained between 2016-2018 from a regional neurological acute hospital with intensive care and early rehabilitation units were investigated (n=55). Patient data was collected and analyzed together with whole-genome sequencing data to investigate antibiotic resistance and virulence determinants of the VREfm. The population structure of VREfm was investigated using the Core genome-based multilocus sequence typing (cgMLST). FINDINGS: The average age of the patients was 67.1 years. For 96% of the patients, a previous hospital stay was reported. 64% of the patients were treated with antibiotics. All VREfm harbored the vanB vancomycin resistance gene. The multilocus sequence types (STs) detected changed abruptly from four different STs in 2016 to a predominant ST in 2017 and 2018 (ST117). Most of the ST117 isolates were members of the cgMLST type CT71. CONCLUSION: The results indicate a sudden shift of the VREfm population structure from a semi-heterogeneous population to a pre-dominant clone within an interval of two years. Further investigations are warranted to understand the epidemiology and emergence of this clone.

[Antibiotic resistance and antibiotic consumption in a region - using the example of community-acquired urinary tract infections]. / Antibiotikaresistenz und Antibiotikaverbrauch in einer Region am Beispiel ambulant erworbener Harnwegsinfektionen.

BACKGROUND: In sight of increasing bacterial resistances, appropriate and cautious antibiotic therapy (antibiotic stewardship) is becoming more and more important, in private practices as well. A current S3 guideline is available for the treatment of uncomplicated urinary tract infections, which recommends that regular epidemiological examinations of pathogen sensitivity are to be carried out promptly and locally. With this said, the antibiotic prescriptions of the resident doctors in Hesse were examined and compared with the sensitivity of the most important pathogens causing urinary tract infections. MATERIAL AND METHOD: The prescription data for antibiotics (ATC J01) for the area of ​​the Association of Statutory Health Insurance Physicians in Hessen for the years 2013 to 2020 were received from Insight Health GmbH & Co. KG, Waldems-Esch, which manages the data. A large laboratory that supplies numerous resident doctors in the Rhine-Main region provided sensitivity data tested according to CLSI until the year 2016 and from 2017 to EUCAST from microbiological examinations of urine samples for the clarification of community-acquired urinary tract infections from the years 2011-2020. RESULTS: From 2013 to 2020 the antibiotic prescriptions decreased from 2 692 370 to 1 708 134 (minus 37 %). The prescriptions for cephalosporins were reduced by more than 40 %, those of quinolones by 76 %. Among the antibiotics recommended for urinary tract infections, the most common antibiotics used were fosfomycin (2020: 130 476), followed by co-trimoxazole (2020: 96 559), nitrofurantoin (2020: 37 415), trimethoprim (2020: 27 388), pivmecillinam (20 984) and nitroxoline (6818). Urologists, on the other hand, most frequently prescribed nitrofurantoin (2020: 9951) and co-trimoxazole (9772), followed by fosfomycin (7193), trimethoprim (5050), nitroxoline (3289) and pivmecillinam (2722). Despite the high use of fosfomycin in outpatient medicine, E. coli and Citrobacter spp. exhibited no loss of sensitivity, Proteus mirabilis and S. aureus showed a slight loss of activity, while in Enterobacter cloacae a clear loss of activity was seen. The E. coli strains detected from urine samples to clarify complicated urinary tract infections show continuously excellent sensitivity for fosfomycin, nitrofurantoin, nitroxoline and mecillinam (> > 90 %), whereas the sensitivity against trimethoprim was just under 80 %. DISCUSSION AND CONCLUSION: The decrease in antibiotic prescription data from statutory health insurance physicians in Hesse shows that the importance of cautious antibiotic therapy is also gaining ground in outpatient practice. Co-trimoxazole, which continues to be used very frequently, should be avoided in favor of monotherapy with trimethoprim because of the increased side effects of the sulfonamide component with the same effectiveness of trimethoprim. The E. coli strains detected from urine samples to clarify complicated urinary tract infections showed a sensitivity, of just under 80 % to trimethoprim. Since an approximately 10 % better sensitivity rate was found for uncomplicated community-acquired urinary tract infections that usually do not require microbiological diagnostics, in our opinion, in transferring this observation in the Rhine-Main area and in Hesse, trimethoprim can also continue to be used empirically for uncomplicated urinary tract infections.

[Children and COVID-19-Data from mandatory reporting and results of contact person testing in daycare centers and schools in Frankfurt am Main, Germany, August-December 2020]. / Kinder und COVID-19: Kontaktpersonen-Surveillance in Frankfurter Kitas und Schulen (August bis Dezember 2020).

BACKGROUND: In face of the coronavirus disease 2019 (COVID-19) pandemic, the question that children are also drivers of this pandemic and that groups, classes, or the entire facility should be closed when severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurs in schools or daycare centers is always implied. These questions were investigated using the mandatory reporting data in Frankfurt am Main and the extensive testing of contact persons (CP) in schools and daycare centers after the occurrence of an index case. METHOD: The reporting data were taken from SurvStat. The index cases from daycare centers and schools were isolated and the CPs were offered PCR testing for SARS-CoV­2 on a voluntary basis, regardless of whether symptoms suggestive of SARS-CoV­2 had occurred or not. Deep nasal/pharyngeal swabs were collected by paramedics on behalf of the public health department of the city of Frankfurt am Main, Germany, and tested according to established standards at two accredited institutes. RESULTS: From March to 31 December 2020, 22,715 COVID-19 cases were reported in Frankfurt, including 1588 (7.6%) SARS-CoV­2 detections in children 14 years and younger. Thus, approximately half as many SARS-CoV­2 detections were reported in children up to 14 years of age than would have corresponded to their proportion in the population. In autumn 2020, the increase in incidence in children over the weeks followed the increase in incidence in the general population, the age-related incidence of children remained below the incidence in the general population.From week 35 to week 52, index cases were reported from 143 daycare centers and 75 schools. As a result, 7915 CPs were tested. In daycare centers, SARS-CoV­2 was detected in 4.5% of adult CPs and 2.5% of child CPs and in schools SARS-CoV­2 was detected in 0.9% of adult CPs and 2.5% of student CPs tested. On average, less than 1 CP tested positive per index case. The rate of positive findings increased with increasing incidence in the overall population. No major outbreak occurred. DISCUSSION: Regarding the level and timing of age-related incidences among children in Frankfurt am Main, there was no evidence that children were the drivers of the pandemic. Only a small percentage of the examined CPs in schools and daycare centers tested positive for SARS-CoV­2. In the absence of evidence of intense transmission in the facilities, CP attendance can/should continue under hygiene conditions and there is no need to close entire groups, classes, or even facilities.

[The School Entrance Examination: Attempted Evaluation by Interviewing Parents, Pediatricians and Schools]. / Die Schuleingangsuntersuchung: Versuch einer Evaluation durch Befragung von Eltern, Kinderärzten und Schulen.

INTRODUCTION: In Germany, school entry examinations (SEU) are mandatory in all (federal) states, the scope and methods of investigation are laid down in state ordinances. The SEUs are performed by the pediatric services (KJGD) of the public health departments. An evaluation of the entire SEU is still pending. Therefore, in 2018, an evaluation of the SEU was carried out in the health department of the city of Frankfurt am Main by interviewing parents, schools and pediatricians. METHOD: With specifically developed questionnaires, parents as well as administrators of elementary schools and pediatricians were asked about their assessment of and their experiences with the SEU. Certain sentences were to be rated on a 5-point Likert scale. For the evaluation, the positive answers (totally agree / agree) and the negative answers (disagree / strongly disagree) were summarized. RESULTS: A total of 2,021 parental, 46 school and 37 physician questionnaires were evaluated. The response rate of parents was 90%, that of schools and pediatricians 45% and 56%, respectively and thus significantly worse. Ninety-one percent of parents rated the SEU as useful in addition to their pediatrician check-ups, and 94% considered hearing and vision tests to be particularly important. Eighty-five percent considered the SEU as an important means of undertaking support measures before school entry. Ninety-one percent of school administrators rated the results of the SEU as helpful, 26% of them stated that key areas, including social behavior were given insufficient consideration in the SEU. Many school administrators wanted more support from the health department, e. g. inclusion issues (59%), parenting evening lectures (61%) or general health support (74%). Ninety-one percent of pediatricians also rated the SEU positively. However, misjudgments of the school doctors and uncertainty of the parents as well as rare exchanges/communication were criticized. CONCLUSION: The overall feedback was positive and the significance of the SEU was not questioned. However, the KJGD should try to better meet the needs of schools for more support and pediatricians' desire for better cooperation. Through a modification of the SEU, capacities could be created for other important tasks of the KJGD, for instance the examination of school newcomers from foreign countries, health promotion in schools, and medical advice to schools.

Antibiotic consumption surveillance in rehabilitation facilities - a new task according to § 23 of the German Infection Protection Act. Data from rehabilitation facilities in the Rhine-Main area, 2016-2018.

Background: Multidrug-resistant pathogens are a major health problem in many countries. In Germany, in accordance with the German Antibiotic Resistance Strategy (DART), the surveillance of antibiotic consumption in acute care hospitals and rehabilitation facilities was made mandatory by the Infection Protection Act in 2011 and 2017. Whereas comparable reference data for acute care hospitals are available, such data is lacking for rehabilitation facilities. Therefore, the Rhine-Main network on MDRO (Multi Drug Resistant Organisms) has offered to evaluate the antibiotic consumption of the network's rehabilitation facilities. Antimicrobial consumption (if possible already given as daily defined doses, DDD) and patient days from 2016-2018 were requested. Materials and methods: By October 31, 2019, nine clinics, including a facility for early neurological rehabilitation, reported their consumption of antibiotics (mostly already as DDD) and patient days from 2016-2018. The information from the clinics was entered in an Excel table and the DDD calculated if necessary. In order to compare the facilities, the DDD/100 patient days (pd) were calculated for the individual active substances. Results: Antibiotic consumption in general rehabilitation facilities decreased slightly from 4.8 DDD/100 pd to 4.4 DDD/100 pd from 2016 to 2018. In early neurological rehabilitation, antibiotic consumption increased from 10.2 DDD/100 pd to 13.1 DDD/100 pd in the same period. Among the most commonly used antibiotics, cefuroxime came first, followed by ciprofloxacin and amoxicillin in third place. Discussion: To our knowledge, this is the first antimicrobial consumption data from rehabilitation facilities in Germany. Antibiotic consumption in general rehabilitation facilities is less than 10% of the consumption in normal/regular wards of acute care clinics, and the consumption in neurological early rehabilitation was approximately 10% of the consumption in intensive care wards within acute care clinics. Reserve or broad-spectrum antibiotics were rarely or not used at all in the rehabilitation facilities. Despite this overall positive situation, antibiotic stewardship should also be introduced in rehabilitation facilities, possibly with the support of the regional MDRO networks.

Sars-Cov-2 in children - insights and conclusions from the mandatory reporting data in Frankfurt am Main, Germany, March-July 2020.

Introduction: From the beginning of the corona pandemic until August 19, 2020, more than 21,989,366 cases have been reported worldwide - 228,495 in Germany alone, including 12,648 children aged 0-14. In many countries, the proportion of infected children in the total population is comparatively low; in addition, children often have no or milder symptoms and are less likely to transmit the pathogen to adults than the other way round. Based on the registration data in Frankfurt am Main, Germany, the symptoms of children in comparison with adults and the likely routes of transmission are presented below. Materials and methods: The documentation of the mandatory reports includes personal data (name, date of birth, gender, place of residence), disease characteristics (date of report, date of onset of the disease, symptoms), possible contact persons (family, others) and i.a. possible activity or care in children's community facilities. All reports were viewed, especially with regard to likely transmission routes. Results: From March 1 to July 31, 2020, 1,977 infected people were reported, including 138 children between the ages of 0 and 14 years. Children had fewer and milder symptoms than adults. None of the children experienced severe respiratory symptoms or the need for ventilation. 62% of the children had no symptoms at all (19% adults), 5% of the children were hospitalized (24% adults), and none of the children died (3.8% adults). After excluding a cluster of 34 children from refugee accommodations and 14 children from a parish, 78% of the remaining 90 children had been infected by an adult within the family, and only 4% were likely to have a reverse transmission route. In 5.5% of cases, transmission in a community facility was likely. Discussion: The results of the registration data from Frankfurt am Main, Germany confirm the results published in other countries: Children are less likely to become infected, and if infected, their symptoms are less severe than in adults, and they are apparently not the main drivers of virus transmission. Therefore, scientific medical associations strongly recommend reopening schools.
