1 Does a higher rate of reported transfusion reactions mean a hospital is safer? Johanna (Jo) Wiersum-Osselton TRIP Hemovigilance and biovigilance office

2 Outline Hemovigilance reporting in The Netherlands Study: does a higher rate of reported transfusion reactions mean that a hospital is safer? Achieving safety improvement: SHOT France Within-hospital learning? What are the ingredients for avoiding errors? How can we bring about improvement?

3 Reports per year Reports per 1000 units distributed After ten years Total reports Serious reports (grade 2,3,4) Reports per 1000 units Still counting, no apparent improvement: no reduction in numbers of reports Is there a parameter which could indicate safety of blood transfusion?

4 Reports 70 Variation in rate of reports per 1000 units Serious TR (excl alloantibodies and mild NHFR) Units transfused

6 TR per 1000 units in Consistency from year to year Consistency from year to year: Linear regression of rate in 2010 with 2009, and blood use level: R 2 = 0.55 (p<0.001) TR per 1000 units in 2009 TR = transfusion reactions: definite, probable or possible, excluding new allo-antibodies and mild febrile reactions

7 % of hospitals Analysis of data TR reporting rate (reports per 1000 units) 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% > to 3.7 <1.8 Hospital annual blood use (total units) TR = transfusion reactions: definite, probable or possible, excluding new allo-antibodies and mild febrile reactions

8 % of hospitals 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Are hospitals with more TR reports safer? Incorrect blood component transfused a possible proxy for unsafe transfusion OR 2.5 ( ) OR 4.2 ( ) adjusted odds ratios Vox Sanguinis < to 3.7 >3.7 Rate of transfusion reaction reporting No IBCT 1 or more Conclusion: the data do not support that hospitals with a higher rate of transfusion reaction reports are safer

9 Hospital factors associated with higher likelihood of IBCT report Presence of transfusion safety officer 1-4 years adjusted OR 2.8, 95% CI vs no TSO All years adjusted OR 2.2, 95% CI vs no TSO Hospital also reported near miss or other incident Near miss adjusted OR 14.2, 95% CI Other incident OR 15.0, 95% CI Hospital also reported alloantibody formation or mild non-hemolytic febrile reactions (<2 o C) Conclusion: Consistent with better surveillance and more complete reporting; it cannot be excluded that hospitals with higher rates of transfusion reactions may have more incorrect transfusions to report.

Reports per 1000 units transfused Consistency of reporting rate 2.5 2 1.5 1 0.5 n=97 hospitals 3 41 31 22 TR rate 2012 0 Reporting level in 2006 Level 1 <1.

11 Reports per 1000 units transfused Consistency of reporting rate n=97 hospitals TR rate Reporting level in 2006 Level 1 <1.8 TR/1000 u Level TR/1000 u Level 3 >3.7 TR/1000 u TR = transfusion reactions: definite, probable or possible, excluding new allo-antibodies and mild febrile reactions

12 Data from SHOT All other IBCT cases ABO incompatible red cell transfusions

13 ABO incompatibility (France) Reduction of ABO incompatible RBC transfusions France RBC Plasma Platelets Contrôle ultime of ABO compatibility at bedside (since 1985); ministerial circular in 2003 stressed importance of identification of patient/unit

14 Incident reports to TRIP Incidents Hospitals with reports (ever) Incorrect blood component transfused ABO-risk* ABO incompatible RBC transfusion Near miss Other incident # *TRIP assessment: risk to which the patient was exposed # includes unnecessary transfusions and (SHOT term) right blood right patient

26 Where next Limitations of HV data Lack of info about uncomplicated transfusions! Problems of underreporting, incomplete information Keep up good data collection (improve efficiency if possible) Results accessible for policymakers and professionals Apply lessons learned: Implement measure Evaluate Tweak Act Plan Do Check
