23 Can prevention succeed in Pakistan? Re-organize the resources Adopt a uniform policy Prenatal Diagnosis and carrier screening Legislation for premarital screening Aggressive campaign Mark the starting point Role of NGOs

24 Aplastic Anaemia (AA) Wide variation in prevalence of AA worldwide Three times more common in Pakistan than the western world Affected patients of AA are much younger Increased incidence in rural areas and low socioeconomical group Genetic factors, chemicals (Arsenic & Benzene), environmental factors (Pesticides) Mostly present as severe or very severe AA

29 Organization of Laboratory Service Lab is an integral part of each public and private sector hospital There are many stand alone laboratories of variable capability Few large private labs with their collection centers through out the country Smaller labs are supervised by clinical pathologist Larger or referral labs have all subspecialties of pathology including haematology

30 Anemia / Thalassemia Blood Transfusion Leukaemias / Lymphomas Hematology Flowcytometry Bleeding Disorders Molecular Analysis Cytogenetics

31 Existing Haematology Facilities PUBLIC Non existent at primary & secondary care hospitals Haematology diagnostic facilities at some tertiary care hospitals A few stand alone haematology specialty centers Armed Forces diagnostic centers PRIVATE Not more than a dozen for a population of 207 M Concentrated in main cities only Cost

40 Challenges in Lab Haematology Haematology facilities and centers are far less considering the population (207 M) Limited health budget and resources Shortage of equipment and trained staff Capacity building and training Quality assurance and lab accreditation Carrier progression and foreign courses for young haematologist and technologist

41 Blood Transfusion Service BT Sector in Pakistan was quite fragmented and disorganized It was not guided by national standards or overseen by regulatory authorities or a national program The system s backbone were multifunctional hospital blood banks, complemented by an ever increasing number of private blood banks Estimated number of blood centers in Pakistan is more than 1800 Annual blood collection is estimated to be approximately 3.5 million units Overwhelming reliance is on replacement donors

42 Safe Blood Transfusion Program In 2008, Govt initiated blood safety systems reforms with the support of the German government to replace the fragmented BTS with centrally coordinated blood transfusion services National Health Policy National Blood Policy National Strategic Framework National Steering Committee Safe Blood Transfusion Law Blood Transfusion Authorities Blood Transfusion Programs Blood safety included as a priority area Proposed establishing a Nat. Blood Transfusion Service Highlighted fundamental principles & reforms areas Strategic body to review reform implementation Legislation reviewed and revised Established at the federal & provincial levels Project established at national & provincial levels

43 Safe Blood Transfusion Program Phase It is based on the centralized model consisting of Regional Blood Centers (RBCs) - Collecting, processing, testing, storing and distributing blood Hospital Blood Banks (HBB) - Storing and issuing blood In Phase I, 10 RBCs and 60 affiliated HBBs completed constructed/refurbished (cover 15% of the blood demand) along with associated technical work.

44 Voluntary Blood Donations National Blood Donor Policy developed in 2012 National Strategy is: Strengthening of University based BDOs Conversion of Replacement Donors to VNRBD General awareness abut blood safety Resource constraints hampering optimum promotion of VNRBD.

45 World Blood Donor Day National Celebrations

46 Safe Blood Transfusion Program - Phase II In Phase II, the scope and coverage will be expanded, additional infrastructure will be created to further expand the RBCs-HBBs network in the country In addition to building more RBCs, large existing public sector HBBs will be upgraded to RBCs and support provided to large NGOs. Reputable private sector BBs will also be co-opted as Collaborating RBCs and technical assistance provided to adapt them to assume their new role. By 2019, about 50 % BT coverage will be through the new system

47 Blood Transfusion Services Pakistan - Challenges Key issue remains lack of governance and will Quality assurance and validation of blood banks Deficiency of trained specialists and technologists in BTS Capacity building and training VNRBD promotion needs to be geared up as the project infrastructure has now become operational The system has improved in last decade but still largely unregulated and unsafe with serious consequences for the public

48 The Way Forward Needs gap analysis in all aspects of hematology services Development of National Haematology Task Force Provision of adequate budget Disease prevention program Recommend optimum equipment Manning level of lab facilities and training Public private partnership Policy for lab/blood bank licensing, regulation, inspection and accreditation

49 Pakistan Society of Haematology (PSH) Established in 1991 Aims and Objectives To promote the advancement of Haematology, including transfusion medicine, through encouragement of research, improvement of technical methods and affiliation with other national and international organizations To provide a forum for persons practicing Haematology and transfusion medicine to discuss problems and to formulate and present agreed viewpoint at national and international forum To offer guidance and training to technologists and residents in order to improve their skills To coordinate and standardize the practice of Haematology through expert committees
