1 Infections in transplants why is it so difficult to collect reasonable data regarding infections? Dr Kate Ward #EBMT2015

2 Why collect infection data? Along with graft-vs.-host disease (GVHD), infection remains a major source of morbidity and mortality in HSCT recipients 2

3 Allograft Adapted from Mandell Infectious Diseases

4 Types of infection & occurrence relative to time after allo-sct Fungi Viruses Candida Aspergillus Herpes simplex/ cytomegalo-, adeno/ varicella-zoster Bacteria Gram-positive Gram-negative encapsulated Pneumonia bacterial non-bacterial* 0 50 Days post-sct 100 >365 * Pneumocystis pneumonia 4

5 How many infections after allo-sct? 5

6 REGISTRY & THE NEED TO COLLECT INFECTION DATA To determine the incidence, morbidity & mortality of important infections Specifically to: Generate annual EBMT epidemiology Update guidelines Note trends in relation to procedures e.g. RIC v myeloablative HSCT Basis for designing future studies 6

7 Currently 90% return What information is collected about infections? 7

8 Clinical Infectious Diseases 59 (2014) HSCT patients, seropositive and seronegative,

9 MED-B & infections in the last decade Only ~20% of (allo) CICs report MED-B routinely Even these 20% are often incomplete Reporting bias Information collected generally insufficient for studies for MED-B level studies need to get back to reporting centre for more information Who in the audience has entered infections on Med-B? 9

10 HIV 28% valid CMV 70% valid EBV 20% valid 10

13 Aspergillus Problem 1 Yes 461 No % incidence BUT unknown 27,896 Is this real?? Aspergillus Problem 2 Definition of documented invasive fungal infection 13

14 Who has used this reference document? Complication a secondary disease/condition aggravating an already existing one.

15 How easy is it to find info about a disease (infectious complication) in the patient s charts?

16 Do you get help from any of the following to identify infection & disease? Nurse Haematologist Microbiologist Virologist 16

17 Bact/fungi/virus/ parasite Total valid Total missing Total valid + missing

18 Bacteraemia is a better term than bloodstream infection since it means bacteria in the blood emphasising the fact that blood is not, in fact, infected but is merely transporting bacteria. Bacteraemia is not a complication unless it is associated with disease 18

34 What does CMV viraemia mean? CMV DNA in blood or CMV antigen in blood Regularly tested for because, if detected antiviral drugs given to PREVENT the complications of CMV pneumonia, retinitis etc CMV disease is RARE but detection of CMV is common. 34

35 How easy is it to find the start date of a particular infection in the patient s charts/notes? 35

36 It is difficult to get the infection data out of the database without a start date for the infection J Hoek

37 Current problems re infection & Med B Data managers insufficient expertise Use of case definitions document June 2012 infections in Promise 100,000 in 37,507 ptts Before, at or after transplant? No exact dates for infections Little information on hospitalisation List of names for infections/pathogens huge 21,000 other infections 37

38 QUESTION Who has used the information on infectious complications and published the results? Almost noone! So we need your suggestions how to make it work! 38

39 WE NEED to STOP THIS! 39

40 What is the Remedy for infections? 40

41 Pick your cherry Hey. Pick me! 41

42 IDWP New Data Structure Med A+ CMV Limited to centres with a clear interest Med A MED A+ H1N1 Limited to survey participants MED A+ Antibiotic resistance Limited to study participants 42

48 What next? The Remedy is specific modules for infection rather than Med-B Design forms for infection module e.g. CMV disease & new antiviral drugs Should be as brief as possible Data managers & physicians work together to solve 48
