[[p.1]] Introduction • Blood transfusion service (BTS) is a vital component of any health care delivery system. • The aim of blood transfusion services should be to provide effective blood and blood products, which are safe as possible and adequate to meet patients’ needs. • A blood transfusion service is a complex organization, requiring careful designing and management. National Blood Policy (2007) A need for modification and changes in the blood transfusion service has necessitated formulation of National Blood Policy (2002, revision 2007).32 Objectives 1. To provide safe and adequate quantity of blood and blood components. 2. To make available adequate resources to develop and re- organize the BTS in the entire country. 3. To make latest technology available for operating the BTS and ensures its functioning in an updated manner. 4. To launch extensive awareness programmed for donor information, motivation, education, recruitment and reten- tion in order to ensure adequate availability of safe blood. 5. To encourage appropriate clinical use of blood and blood products. 19 Blood Bank Organization and its Management 171 [[p.2]] 172 Essentials of Blood Banking and Transfusion Medicine 6. To strengthen the manpower through human resource development. 7. To encourage research and development in the field of trans- fusion medicine. 8. To take adequate regulatory and legislative steps for monitoring and evaluation of blood. Transfusion services and to take steps to eliminate profiteering in blood banks. General Considerations for Setting Up a Blood Bank • General guidelines • Basic structure and designing of a blood bank • Location • Aims and operating policies • Staffing pattern • Personnel management General Guidelines • Location – Not exposed to strong sunshine – Proper natural lighting of rooms and protection from dust and insects – Adequate protection against rains and snow – Stand by generator • Equipment and instruments for different sections • Utilities—water, electricity, fuel • Consumable supplies • Lab reagents, bags, etc. • Office supplies • Quality control program followed in BTC • Laboratory safety precautions • Basic financial consideration and budgeting. Building • Located in hospital premises • Provides easy access for donors and staff, allows quick and safe transportation of blood and components • Well lighted, ventilated protected • Away from sewage, drain or similar unhygienic surroundings.

Medicolegal Concerns and Ethical Aspects Blood transfusion services in a blood bank have high potential risk of adverse reactions to recipients and high risk of legal liability to hospital. Risks include • Acceptance of donor • Extraction of blood • Storage of blood and its derivative • Procedures like grouping, crossmatching • Transfusion to the donor [[p.9]] Blood Bank Organization and its Management 179 Documentation and Record Maintenance • To judge the performance of blood bank • To trace any unit of blood from its source to final position • In legal or investigation process • Compilation of statistical data of performance monthly and yearly • Written as well as computerized documentation and records should be maintained. Various records to be maintained • Blood donor record including rare donor panels, donor referrals and donor reactions • Master records • Issue register • Records of blood bags • Transfusion adverse reaction records • Recipient’s register • Blood stock register • Register of blood grouping and crossmatching • Register for grouping and typing of OPD and ward patients • Records of apparatus, reagents, etc. • Quality control records • Patient/recipient’s record • Attendance registers for staff Quality Assurance • Customer focused, strategic and systemic approach to conti- nuous improvement involving all persons in the organization. • Provides opportunity for all staff to be a part of team approach. • Provides common structure for improvement of problems and processes. • Customer needs to be satisfied with quality services, on time and at best possible cost. Quality Control • Testing routinely performed to ensure proper functioning of materials, equipment and methods. [[p.10]] 180 Essentials of Blood Banking and Transfusion Medicine • QC performance characteristics and acceptable ranges should be readily available for the prompt detection and appropriate handling of unacceptable variations. • A separate QC department and medical officer should take appropriate actions. • It includes: – Proper construction of premises – Continuous monitoring of the equipment – Competence of the personnel – Testing of defined number of units of each product for appropriate parameters – When unfavorable results—procedures must be reviewed and appropriate measures taken – Proper documentation and record maintenance According to Drugs and Cosmetics Act it is mandatory that in any storage equipment in the blood bank the following are a must: • Digital display of temperature inside • Thermograph • Alarm system • Temperature of the thermometer should be compared periodically to the temperature on the recording chart • A difference of more than 2°C is not acceptable. Accreditation Laboratory accreditation is a procedure by which an authorita- tive body gives formal recognition that a laboratory is compe- tent to carry out specific tasks based on third party assessment. Emphasis is on technical competence which also includes quality system management • Currently Drugs and Cosmetic Rules under Government of India,33 provide accreditation services for blood bank. • With the national blood policy now in place, the government is all set to take the next step towards improving transfusion services in the country. • National Aids Control Organization (NACO)34 plans to come up with an accreditation programmed for blood banks, blood storage centers and other centers involved in providing transfusion services. [[p.11]] Blood Bank Organization and its Management 181 Worldwide accreditations for blood banks • Food and Drug Administration (FDA) • American Association of Blood Banks (AABB) • College of American Pathologists (CAP) • National Committee for Clinical Laboratory Standards (NCCLS) Legislation • India has a procedure for mandatory licensing under the Drugs and Cosmetics Rules for blood banks. • Any blood bank can function only if it qualifies the criteria laid down by the organization. • These range from quality and variety of the equipment used, to the qualification of the working staff, source of procure- ment of blood and blood components to labeling of blood units/components licensing is renewed every year if trans- fusion center fulfils all specifications.
