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

The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors of the blood bank of a tertiary institution. The blood donor incident book was reviewed for the period of six months. Negative undesirable events occurred in 2% of the donor populations, of which 45.8% could not complete the blood donation process while only 16.7% completed the blood donation process. Mild vasovagal attack occurred in 0.2% of the donor population. Undisclosed deferrable risk factors/ behaviours were identified by the phlebotomist in the bleeding room which made donors unfit for donation even though they had passed the donor screening criteria. This accounted for 20.8% of those with negative experience. Guidelines are required to identify donors that are not likely to complete donation to avoid wastage of time, blood, resources and reduce undesirable experiences

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

ABSTRACT

Background: Performing major surgery in a child demands that blood is cross-matched and saved to be transfused as indicated. Because the cost of cross-matching and donation of blood can be enormous and may equal or surpass the cost of surgery in our setting; it is pertinent to evaluate its utilization. The aim of this study was to determine how banked blood meant for pediatric surgical procedures was utilized with the hope of streamlining our blood requisition policy. This may be useful to pediatric and other surgeons involved in the operative care of children in similar settings. Materials and Methods: This was a prospective study of all children who had ELECTIVE or EMERGENCY surgical procedures between January 2009 and June 2010. The age; sex; nature of surgery; blood loss; banked units of blood and amount transfused were collected and analyzed. Results: Eighty two patients had 81 units of blood banked for them. Forty - eight and half units (59.9) of the banked blood were for the emergency group but only 18 units (22.2) were actually transfused at the end (P = 0.044) leading to inadequate use of the product. Conclusion: Banking large quantities of blood but utilizing only little is tantamount to inadequate use and delays surgical intervention. Indirectly; it increases cost of surgery. There is need to rationalize our blood ordering habits without causing harm to patients

ABSTRACT

Les banques de sang representent des organismes autorises et specialises ayant la responsabilite du stockage et de la conservation du sang humain; en prevision d'une transfusion sanguine. La collecte; le don; le traitement et la conservation du sang ne constituent pas des operations anodines et comportent des risques importants. C'est dire l'interet de l'organisation rigoureuse et methodique d'une banque de sang particulierement dans la lutte contre les maladies sexuellement transmissibles par le sang

ABSTRACT

Le guide pratique de la transfusion a ete concu comme un outil dont la destination est triple a savoir informer le personnel medical sur les causes d'anemie au Zaire et leur prevention; aider le personnel medical a poser correctement les indications de la transfusion sanguine de facon a eviter toute transfusion qui ne soit pas indispensable; compte tenu des risques importants de cette therapeutique et; fournir a ce personnel les informations utiles et les instructions pratiques concernant le recrutement des donneurs; les examens a pratiquer sur le sang donne; l'application de la transfusion ainsi que l'information du donneur sur les resultats des examens effectues sur son sang. Il s'adresse donc a toute personne faisant partie du corps medical et paramedical; aussi bien au medecin exercant dans un hopital qu'a l'infirmier travaillant dans un centre de sante en milieu urbain ou rural
