Provider trends in paediatric and adult transfusion reaction reporting.

BACKGROUND AND OBJECTIVES: Passive transfusion reaction reporting systems fail to capture a significant number of reactions, and no data exist on provider reporting trends. The aim of this study was to describe transfusion reaction reporting patterns by adult and paediatric providers. MATERIALS AND METHODS: This is a multihospital study on transfusion reaction reporting over a 7-year period. Reports were categorized according to transfusion location and assigned to either a transfusion reaction or nonreaction group according to Centers for Disease Control imputability guidelines. Included in the reaction group (RXN) were definite, probable or possible reaction categories; with the remainder assigned as nonreactions (NORXN). Rates were calculated per 100,000 components transfused using chi-square comparison. RESULTS: There were 1092 reports generated from 363 437 transfusions; 230 reports from 69 311 paediatric and 862 reports from 294 126 adult treatment areas. The reporting rate per 100 000 components transfused was 332 for paediatric and 293 for adult (P = 0·09). The per 100 000 components transfused rates were as follows: 237 for paediatric and 169 for adult (P < 0·01) in the RXN group; with 95 paediatric and 124 adult rates in the NORXN group (P = 0·04). CONCLUSION: The total number of reports generated by paediatric and adult providers was not significantly different, suggesting that both provider groups engage the passive reporting system equally. However, paediatric providers reported more true reactions compared to adult providers. Robust hemovigilance systems will further the understanding of these trends and may aid in the development of targeted provider education programmes.

Granulocyte transfusion therapy in pediatric patients after hematopoietic stem cell transplantation: a 5-year single tertiary care center experience.

BACKGROUND: Granulocyte transfusion (GTx) has been used in neutropenic patients to treat infections; however, there are few studies that document its efficacy, especially in pediatric patients after hematopoietic stem cell transplantation (HSCT). We, therefore, reviewed the use of GTx in these patients. MATERIALS AND METHODS: A retrospective observational analysis was performed on all pediatric HSCT patients between January 2005 and January 2010 who met our institution's criteria for GTx and received more than 1 GTx. Unstimulated granulocyte donors were used until June 2007, followed by dexamethasone-stimulated donors thereafter. Outcomes were infection clearance, safety profile of GTx, and 30-day survival. RESULTS: One hundred fifty-three GTxs were administered to 16 pediatric HSCT patients. Indications for GTx: bacterial (69%), fungal (19%), and combined infection (12%). Concurrent infections, mostly bacterial, developed in 60% patients. One adverse reaction (pulmonary toxicity) was reported. The absolute neutrophil count of the stimulated products was significantly higher compared with the unstimulated products; however, neither the average number of granulocytes transfused by weight nor outcomes difference was noticed between these groups. CONCLUSIONS: GTx is safe in neutropenic and infected pediatric patients after HSCT. However, no difference in the outcomes was noticed between the group that received stimulated products and the group that received unstimulated products.
