The purpose of this study is to determine the efficiency of blood utilization for elective surgery at the University of Malaya Medical Centre (UMMC). A similar study conducted six years earlier in the same unit resulted in the introduction and implementation in December 1997 of the local Maximum Surgical Blood Order Schedule (MSBOS) and the Group Screen and Hold (GSH) procedure instead of a full crossmatch. This paper compares the findings of the current study with that conducted earlier.

Induction of remission of acute promyelocytic leukaemia (APL) needs intensive blood support (16) to prevent bleeding attributed to disseminated intravascular coagulation. Between 1989 and 1991, at the University Hospital in Kuala Lumpur, Malaysia, the remission rate of APL was only 27% with conventional chemotherapy as a result of inadequate transfusion resources. The use of all trans retinoic acid in induction therapy followed by consolidation and maintenance chemotherapy has improved the situation dramatically. Twelve patients entered the study. Ten patients achieved remission (83%), indicating how ATRA had significantly improved the results (p = 0.003). Blood component transfusions were also significantly reduced (p = 0.003). Two ethnic Chinese patients developed pulmonary leucostasis. Published Chinese (2, 6) and Japanese (11) studies have not reported this serious adverse effect. We can now state that leucostasis is not a phenomenon limited to the Western population. ATRA has proved to be extremely beneficial for patients at this centre. Early analysis also suggests that consolidation and maintenance chemotherapy has prolonged remission duration. ATRA should be made available for the treatment of APL in all countries where there are inadequate transfusion services.

Hemovigilance like quality systems and audits has become an integral part of the Blood Transfusion Service (BTS) in the developed world and has contributed greatly to the development of the blood service. However developing countries are still grappling with donor recruitment and efforts towards sufficiency and safety of the blood supply. In these countries the BTS is generally fragmented and a national hemovigilance program would be difficult to implement. However a few developing countries have an effective and sustainable blood program that can deliver equitable, safe and sufficient blood supply to the nation. Different models of hemovigilance program have been introduced with variable success. There are deficiencies but the data collected provided important information that can be presented to the health authorities for effective interventions. Hemovigilance program modeled from developed countries require expertise and resources that are not available in many developing countries. Whatever resources that are available should be utilized to correct deficiencies that are already apparent and obvious. Besides there are other tools that can be used to monitor the blood program in the developing countries depending on the need and the resources available. More importantly the data collected should be accurate and are used and taken into consideration in formulating guidelines, standards and policies and to affect appropriate interventions. Any surveillance program should be introduced in a stepwise manner as the blood transfusion service develops.
