Surveillance in Poland: BINet experience Anna Skoczyńska National Reference Centre for Bacterial Meningitis
Poland ~ 38 mln 2007 introduction of vaccination against Hib No mass vaccination against pneumococci (only risk groups)
Polish surveillance system for invasive bacterial infections 1997 establishment of the National Reference Centre for Bacterial Meningitis (NRCBM) Until 2005 only meningococcal and H. influenzae meningitis cases were reported Others were notified as other bacterial meningitis (incl. S. pneumoniae) Mandatory reporting of cases for all age groups Two notification systems Obligatory: based on MD reports (NIPH-National Institute of Hygiene) Voluntary: laboratory based (the NRCBM)
Beginning.. meningitis cases only 350 300 250 N. meningitidis S. pneumoniae H. influenzae no of isolates 200 150 100 50 0 1997 1998 1999 2000 2001 2002 2003
IMD associated with very high mortality in the North-West of Poland April 2003 - April 2004: 21 IMD cases, total CFR = 42.9% all the fatal cases were diagnosed as fulminant meningococcal septicemia The situation in the studied area accelerated changes in the registration system currently there is a compulsory notification of all invasive cases
After changes in registration system 350 300 250 N. meningitidis S. pneumoniae H. influenzae no of isolates 200 150 100 50 0 1997 1998 1999 2000 2001 2002 2003 2004 2005
IMD outbreaks in Poland, 2006-2007 Skwierzyna III.2006 (4) Warszawa I.2007 (15) Brzeg II.2007 (7) Kluczbork 2007 (5) Bytom VI.2006 (3) MenC, ST-11
After IMD outbreaks no of isolates/pcr+ 350 300 250 200 150 100 N. meningitidis S. pneumoniae H. influenzae 50 0 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007
2008 project BINet was established to enhance laboratory based surveillance of community-acquired invasive bacterial infections in Poland N. meningitidis S. pneumoniae H. influenzae S. pyogenes S. agalactiae E. coli L. monocytogenes S. aureus* Coordination by the NRCBM Every lab can send isolates and also clinical material from IBI for non-culture diagnostic For laboratories involved in the project, shipment of isolates/materials and diagnostics is free of charge Currently ~ 180 hospital labs involved in the net Lębork Gdynia Gdańsk Elbląg Tczew Koszalin Malbork Kętrzyn Kościerzyna St.Gdański Suwałki Gryfice Biskupiec Olsztyn Goleniów Szczecin Grudziądz St.Szczec.

Remarks after years of surveillance More isolates and materials sent to the NRCBM More patient s data collected (NRCBM - phone calls) Transport free of charge Diagnostic free of charge But also Better contact with microbiologists and clinicians Education: meetings, lectures, newsletters, publications, consultations The NRCBM website with needed information
Problems with surveillance system Lack of regulations (law) Funding Long time only meningitis was notified (IPD meningitis ~ 30%) Rare blood sampling Prior antibiotic therapy (IPD ~ 30%) PCR more often used for suspected IMD Compulsory vs voluntary notification More and more data expected More and more detailed characteristics needed
