An Incitative Multifaceted PROcedure for Pneumococcal Vaccination at the Emergency Department

Pneumococcal Infections

Background : Community-acquired pneumonia (CAP) is a threat in industrialized countries. It represents the 6th cause of death. CAP also frequently associates with other disorders responsible for admission and death. Among bacteria responsible for CAP, Streptococcus pneumonia is a major pathogen that is commonly involved and frequently leads to severe infection and admission. Categories at risk for this pathogen have been determined, and can be proposed anti-pneumococcal vaccination (APV) that efficiently and safely protects from this microorganism. In the context of US health services, monocenter pilot experiences have reported improvement of pneumococcal prophylaxis implementing vaccination procedure at ED. A study that set in New Mexico (2003) reported a significant increase in APV (from 18% to 84%) when patients at risk were proposed vaccination at ED. To obtain these results, medical students were specifically trained and dedicated to screen and vaccinate against St. pneumoniae. Another single center trial (Tennessee, 2007) for APV at ED obtained an improvement (from 38.8 to 45.4%) when physicians were alerted for pneumococcal risk by the software they usually utilized at bedside. However these experiences remain sparse as additional dedicated resources are required or patients and attending ED physicians can be reluctant to proceed to vaccination at ED. Mobile phone and derived communication modalities are current vectors to deliver information in several fields including education and medicine. Initially used in developing countries, short-message services (SMS) have improved behaviour of patients in various medical areas. In France, the investigators have observed that most patients above 50 years of age admitted after ED visit are equipped with mobile phone and can receive alerts by SMS. These observations prompt us to propose a multifaceted procedure to improve APV after ED visit in at-risk patients, combining structured oral interview, written information and SMS as reminders. Purpose : The investigators hypothesized that a multifaceted intervention to promote anti-pneumococcal vaccination combining a structured oral interview, a written information to patient and his/her general practitioner, and a series of 3 SMS, improves anti-pneumococcal vaccination at 6 months, in at-risk patients (65+ years) visiting the emergency department. In order to answer this question, the investigators designed an interventional prospective multicenter randomized study (cluster).

Prevalence of Nasopharyngeal Carriage of Streptococcus Pneumoniae in Healthy Children of 12-18 Months...

Streptococcus Pneumoniae Infections

This study is to observe the carriage rate of Streptococcus pneumoniae (S.p.), Haemophilus influenzae Type B (Hib) and Moraxella catarrhalis (M.Cat.) in healthy Chinese children aged 12-18 months in order to estimate the prevalence of pathogens that commonly cause infection in Chinese young children. The antibiotic resistance of all isolates and the serotypes distribution of S.p. isolates will also be tested. Potential risk factors for nasopharyngeal carriage will be collected.

Pneumococcal InfectionsLymphoma2 more

Pneumococcal infections remain frequent and potentially fatal. To prevent them, two anti-pneumococcal vaccines exist: a 13-valent conjugate vaccine (Prevenar®) and a 23-valent polysaccharide vaccine (Pneumovax®). For their utilization, several studies approved a prime-boost strategy. It consist two administer Pneumovax® at least two months later than Prevenar®. Patients with diffuse large B-cell Lymphoma (DLBCL) have a higher-risk to develop a pneumococcal infection. The main reason is immunosuppression, induced by rituximab (B cell depletion), chemotherapy and lymphoma. Patients are treated by immunochemotherapy, combining rituximab (anti-CD20 monoclonal antibody) and conventional chemotherapy (CHOP). However, those patients have a low rate of vaccination (about 15%).

Surveillance of Invasive Pneumococcal Infections in Adults (Excluding Meningitis)

Pneumococcal Infections

Given the frequency and severity of invasive pneumococcal infections and questions about the place of VPC-13 in the prevention of pneumococcal infections in adults based on the presence of risk factors, current laboratory surveillance should be supplemented with data on the clinical features of adult invasive pneumococcal infections (IPI) cases. In particular it is necessary to collect for these cases, the clinical forms, the severity and the existence of risk factors and to make the link between these characteristics and those strains of pneumococci responsible for the IPI in particular, their serotype. The follow-up of the evolution of the cases according to the presence of risk factors, their clinical form and their serotype coverage (vaccine strain or not) must to guide recommendations for adult VPC-13 and to monitor the effects of VPC-13 vaccination recommendations. These effects are indirect, linked to the effect of vaccination of children with VPC-13 since 2010, which modifies the serotypes responsible for infections in vaccinated and unvaccinated patients, and the direct effects of possible use of the conjugate vaccine in adults (according to the recommendations that will be given by the Vaccination Technical Committee of the High Council of Public Health). The project is based on the existing network of 23 Regional Pneumococcal Observatories (ORP) located in metropolitan France and the network of infectious diseases by completing the microbiological collection of strains of pneumococci isolated from invasive infections in adults by a clinical collection in hospitals or voluntary clinics where the laboratory participates in the ORP. Given the establishment in 2012 of an adult bacterial meningitis observatory, to which the ORP are associated, this project does not include the surveillance of pneumococcal meningitis in adults.
