Case definitions for aseptic meningitis, encephalitis, myelitis, and acute disseminated encephalomyelitis (ADEM) are available, but rarely put to use. The VACC-Tool (Vienna Vaccine Safety Initiative Automated Case Classification-Tool) is a mobile application enabling immediate case ascertainment based on consensus criteria at the point-of-care. The VACC-Tool was validated in a quality management program in collaboration with the Robert-Koch-Institute. Results were compared to ICD-10 coding and retrospective analysis of electronic health records using the same case criteria. Of 68,921 patients attending the emergency room in 10/2010-06/2013, 11,575 were hospitalized, with 521 eligible patients (mean age: 7.6 years) entering the quality management program. Using the VACC-Tool at the point-of-care, 180/521 cases were classified successfully and 194/521 ruled out with certainty. Of the 180 confirmed cases, 116 had been missed by ICD-10 coding, 38 misclassified. By retrospective application of the same case criteria, 33 cases were missed. Encephalitis and ADEM cases were most likely missed or misclassified. The VACC-Tool enables physicians to ask the right questions at the right time, thereby classifying cases consistently and accurately, facilitating translational research. Future applications will alert physicians when additional diagnostic procedures are required.}, language = {en} } @article{SeeberConradHoppeetal., author = {Seeber, L. and Conrad, Tim and Hoppe, Christian and Obermeier, Patrick and Chen, X. and Karsch, K. and Muehlhans, S. and Tief, Franziska and Boettcher, Sindy and Diedrich, S. and Schweiger, Brunhilde and Rath, Barbara}, title = {Educating parents about the vaccination status of their children: A user-centered mobile application}, series = {Preventive Medicine Reports}, volume = {5}, journal = {Preventive Medicine Reports}, doi = {10.1016/j.pmedr.2017.01.002}, pages = {241 -- 250}, abstract = {Parents are often uncertain about the vaccination status of their children. In times of vaccine hesitancy, vaccination programs could benefit from active patient participation. The Vaccination App (VAccApp) was developed by the Vienna Vaccine Safety Initiative, enabling parents to learn about the vaccination status of their children, including 25 different routine, special indication and travel vaccines listed in the WHO Immunization Certificate of Vaccination (WHO-ICV). Between 2012 and 2014, the VAccApp was validated in a hospital-based quality management program in Berlin, Germany, in collaboration with the Robert Koch Institute. Parents of 178 children were asked to transfer the immunization data of their children from the WHO-ICV into the VAccApp. The respective WHO-ICV was photocopied for independent, professional data entry (gold standard). Demonstrating the status quo in vaccine information reporting, a Recall Group of 278 parents underwent structured interviews for verbal immunization histories, without the respective WHO-ICV. Only 9\% of the Recall Group were able to provide a complete vaccination status; on average 39\% of the questions were answered correctly. Using the WHO-ICV with the help of the VAccApp resulted in 62\% of parents providing a complete vaccination status; on average 95\% of the questions were answered correctly. After using the VAccApp, parents were more likely to remember key aspects of the vaccination history. User-friendly mobile applications empower parents to take a closer look at the vaccination record, thereby taking an active role in providing accurate vaccination histories. Parents may become motivated to ask informed questions and to keep vaccinations up-to-date.}, language = {en} } @article{TiefHoppeSeeberetal., author = {Tief, Franziska and Hoppe, Christian and Seeber, L. and Obermeier, Patrick and Chen, X. and Karsch, K. and Muehlhans, S. and Adamou, E. and Conrad, Tim and Schweiger, Brunhilde and Adam, T. and Rath, Barbara}, title = {An inception cohort study assessing the role of bacterial co-infections in children with influenza and ILI and a clinical decision model for stringent antibiotic use}, series = {Antiviral Therapy}, volume = {21}, journal = {Antiviral Therapy}, doi = {10.3851/IMP3034}, pages = {413 -- 424}, abstract = {BACKGROUND: Influenza-like illness (ILI) is a common reason for paediatric consultations. Viral causes predominate, but antibiotics are used frequently. With regard to influenza, pneumococcal coinfections are considered major contributors to morbidity/mortality. METHODS: In the context of a perennial quality management (QM) programme at the Charit{\'e} Departments of Paediatrics and Microbiology in collaboration with the Robert Koch Institute, children aged 0-18 years presenting with signs and symptoms of ILI were followed from the time of initial presentation until hospital discharge (Charit{\'e} Influenza-Like Disease = ChILD Cohort). An independent QM team performed highly standardized clinical assessments using a disease severity score based on World Health Organization criteria for uncomplicated and complicated/progressive disease. Nasopharyngeal and pharyngeal samples were collected for viral reverse transcription polymerase chain reaction and bacterial culture/sensitivity and MaldiTOF analyses. The term 'detection' was used to denote any evidence of viral or bacterial pathogens in the (naso)pharyngeal cavity. With the ChILD Cohort data collected, a standard operating procedure (SOP) was created as a model system to reduce the inappropriate use of antibiotics in children with ILI. Monte Carlo simulations were performed to assess cost-effectiveness. RESULTS: Among 2,569 ChILD Cohort patients enrolled from 12/2010 to 04/2013 (55\\% male, mean age 3.2 years, range 0-18, 19\\% {\ensuremath{>}}5 years), 411 patients showed laboratory-confirmed influenza, with bacterial co-detection in 35\\%. Influenza and pneumococcus were detected simultaneously in 12/2,569 patients, with disease severity clearly below average. Pneumococcal vaccination rates were close to 90\\%. Nonetheless, every fifth patient was already on antibiotics upon presentation; new antibiotic prescriptions were issued in an additional 20\\%. Simulation of the model SOP in the same dataset revealed that the proposed decision model could have reduced the inappropriate use of antibiotics significantly (P{\ensuremath{<}}0.01) with an incremental cost-effectiveness ratio of -99.55?. CONCLUSIONS: Physicians should be made aware that in times of pneumococcal vaccination the prevalence and severity of influenza infections complicated by pneumococci may decline. Microbiological testing in combination with standardized disease severity assessments and review of vaccination records could be cost-effective, as well as promoting stringent use of antibiotics and a personalized approach to managing children with ILI.}, language = {en} } @article{ConradRathTiefetal., author = {Conrad, Tim and Rath, Barbara and Tief, Franziska and Karsch, K. and Muehlhans, S. and Obermeier, Patrick and Adamou, E. and Chen, X. and Seeber, L. and Peiser, Ch. and Hoppe, Christian and von Kleist, Max and Schweiger, Brunhilde}, title = {Towards a personalized approach to managing of influenza infections in infants and children - food for thought and a note on oseltamivir}, series = {Infectious Disorders - Drug Targets}, volume = {13}, journal = {Infectious Disorders - Drug Targets}, number = {1}, pages = {25 -- 33}, language = {en} }
