Surveillance of Clostridium difficile Infections

Clostridium difficile infections (CDI), in particular due to hypervirulent strains, are a major cause of healthcare-associated infections. Surveillance of CDI according to the surveillance protocol is compulsory for acute care hospitals since 2007. For at least 6 months per year (first or last 6 months of the year), hospitals have to register all cases of CDI in the institution. This is a patient-based surveillance (as opposed to aggregated data): the unit of the database is the infection. These data are used to compute incidence rates at hospital and national level.

Additional information	There is no specific budget for this database, it is part of the larger funding for the unit National Surveillance of Infections in Hospitals.In practice, hospitals receive a certain amount of money from the SPF/FOD, and they transfer this money to our unit when participating to surveillance. National Institute for Health and Disability Insurance: funding for the data collection by healthdata.be.

Objective of the project
Main objective of the project	Op het niveau van het ziekenhuis: De incidentie meten en volgen in de tijd (bijv. voor het opvolgen van het effect van geïmplementeerde richtllijnen) Microbiologisch luik: identificeren van de genotypische karakteristieken van de geïsoleerde C. difficile stammen door de samenwerking met het nationaal referentielaboratorium (binair toxine, deletie van tcdC, ribotyping) Op nationaal niveau: Opvolgen van de nationale incidentie van CDIs Opvolgen van de klinische ernst van CDIs Microbiologisch luik: identificeren van C.difficile stammen in Belgische ziekenhuizen en beschrijven van de epidemiologie op landelijk niveau

Design of the project

Principal inclusion and exclusion criteria
Principal inclusion criteria	Alle CDI-patiënten opgenomen in het ziekenhuis gedurende elke periode van surveillance (6 maanden). Patiënten in dagopname of ambulante patiënten (bv. voor dialyse) waarbij CDI wordt vastgesteld, mogen ook in de surveillance worden opgenomen voor wat de infectiegegevens betreft. Deze patiënten mogen echter niet in de noemergegevens opgenomen worden (zie paragraaf 5). Evenmin zullen ze meegenomen worden in de analyses voor de bepaling van de CDI-incidenties.

Data transfer frequency
Data transfer frequency	Ad hoc (event based)
Other frequency: specification	Minimale participatieperiode voor deze surveillance bedraagt 6 maanden, maar aan de ziekenhuizen wordt het sterk aangeraden om gedurende het ganse jaar deel te nemen: De extra werklast voor deelname gedurende het ganse jaar is beperkt : 75% van de ziekenhuizen hebben minder dan 15 gevallen per semester. In het kader van een lokale verbetering, is het noodzakelijk om gedurende het ganse jaar gegevens te verzamelen. De incidentie van C. difficile is seizoensgebonden. Deelname gedurende een gans jaar laat toe om een jaarlijkse incidentie te berekenen. De surveillance gebeurt per semester (van 1 januari tot 30 juni en/of van 1 juli tot 31 december) en data dient te worden doorgegeven ten laatste 3 maanden na het einde van het semester.

Procedures for checking and validating the source data	Validation levels are incorporated in the data collection process: Validation rules: validation rules are the set of predefined and functional definitions that are defined by the responsible researcher of organization. Every new registration entered in the application needs to comply to these validation rules before they can be transferred. Revision: a revision of the data is done by the responsible researcher after receiving the data to exclude any anomaly that was not detected by the validation rules.
Data compilation process	Data cleaning, descriptive analyses
