Abstract
We assessed healthcare worker's knowledge-attitude-practice regarding bacterial contamination of blood products in the Democratic Republic of the Congo. In three hospitals and the National Blood Transfusion Center (NBTC), two multiple-choice surveys were completed on a tablet computer: one each, for blood bank (31 questions) and for clinical ward staff (20 questions). A score was calculated for 11 overlapping knowledge questions. Among 247 participants (blood bank No.=62, ward No.=185), median (range) knowledge score was 10 (2-19) on a maximum of 20, with blood bank staff (12/20) scoring higher than clinical ward staff (9/20) (p<0.0001). Half (50.2%) of 247 participants recalled previous training in transfusion medicine. Participants had limited understanding of and compliance with NBTC-recommended preventive measures: incorrect assumption that wearing gloves prevents bacterial contamination (83.8%) and that blood banks test donor blood for bacteria (59.9%). Half (50.0%) of blood bank staff did not acknowledge the NBTC-recommended antisepsis procedure, 62.1% did not apply the appropriate number of antisepsis steps, and 32.3% saw no harm in touching the venipuncture site after antisepsis. Presence of bacteria on healthy skin (62.3%) and blood bank fomites (examination gloves: 30.8%, soap: 62.8%) was underestimated. Although 92.4% of clinical ward staff said to easily recognize transfusion reactions, only 15.7% recognized septic reactions and post-transfusion antibiotic treatment practices were not consistent. Challenges reported by blood bank staff and particular for low-resource settings were: frequent power cuts (98.4%), transport of blood products by patient attendants (41.1%), without cooling elements (64.4%), and reuse of finished antiseptic/disinfectant containers (75.4%). The present study points to gaps in knowledge, attitudes, practices along sampling, cold chain and transfusion which can feed customized training and monitoring.
