ABSTRACT

Introduction: The transfusion of emergency blood is an essential part of haemostatic resuscitation. Locally, where direct access to a blood bank is limited, emergency blood is stored within emergency centres. It was previously suggested that stored blood provides inadequate volumes compared to what is needed. Minimal data are available regarding indications for emergency blood usage. We aimed to describe the utilisation of emergency blood in selected Cape Town emergency centres. Materials and methods :A cross-sectional study was carried out at three secondary level emergency centres (no blood bank), and one tertiary centre (with a blood bank). Data from emergency blood recipients were recorded over a three-month study period. Indications for transfusion, number of units and location of transfusion were recorded. Indications and usage location were described in numbers and proportions. Results : A total of 329 emergency blood units were transfused to 210 patients. Trauma accounted for 39% (n = 81) of cases and other surgical conditions for 22% (n = 47), particularly upper gastrointestinal 11% (n = 24) and perioperative bleeding 8% (n = 16). Medical conditions accounted for 15% (n = 31), with anaemia 13% (n = 27), the most prevalent indication. Gynaecological conditions accounted for 15% (n = 32), mostly ectopic pregnancy 8% (n = 17). The majority of emergency blood, 77% (n = 253) were used in the emergency centres or operating theatres, 6% (n = 21).Conclusion :Trauma remains a major indication for emergency blood transfusion in this setting. This study questions the use of emergency blood for certain non-urgent diagnoses (i.e. anaemia). Given the scarcity of this resource and limitations to access, appropriate use of emergency blood needs to be better defined locally. Ongoing monitoring of the indications for which emergency blood is used, improved transfusion stewardship and better systems to access emergency blood should be a priority in this setting

ABSTRACT

Objective: To determine whether or not pre-donation testing of blood donors affords substantial cost savings without compromise to blood transfusion safety. Predonation testing of blood donors for Transfusion Transmissible Infections (TTIs) is done in most developing countries because substantial cost savings are made from resources; materials and man-hours which would have been spent to procure infected blood units. Simple rapid test kits used in pre-donation testing is not as sensitive as the Enzyme Linked Immuno-sorbent Assay (ELISA) method used in post-donation screening in a quality assured manner. Design: It is a retrospective study where records of pre- and post-donation tests done in donor clinic of University of Ilorin Teaching Hospital; between January and December 2010 were retrieved. All processes and inputs were evaluated and costs calculated for predonation testing by simple rapid techniques and post donation screening by ELISA. Results: 5000 prospective donors were tested in the study period. The cost of single rapid Pre-donation testing was less than that of single ELISA Postdonation screen. The cost of double rapid Pre-donation and Post donation ELISA screen exceeded the cost of single post donation ELISA screen. Substantial cost savings were made when single rapid Pre-donation testing is relied on. More blood units were found reactive for the TTIs with the more expensive Postdonation ELISA. Conclusion: Pre-donation testing of blood donors was not cost effective. Although; there is an apparent savings if pre-donation testing is not followed by postdonation ELISA testing; it is done at a compromise to blood transfusion safety
