Introduction:
A database is a collection of persistent data that is used by the application
systems of a given enterprise. Traditional databases are organized by
fields, records, and files. A field is a single piece of information; a record
is one complete set of fields; and a file is a collection of records. To
access information from a database, we need a database management
system (DBMS). This is a collection of programs that enables the service
providers and clients to enter, organize, and select data in a database.
Presently in Bangladesh 113 Safe blood transfusion centers are providing
safe blood to the clients. The effective management of blood transfusion
program encompasses a good number of areas and one of the areas is
development of data base for the safe blood transfusion centers and also
for the donors. The development of a data base always needed good
documentation. Documentation provides the ability to trace prospectively
and retrospectively all steps in all procedures, dating from collection of the
blood to monitoring techniques, component preparation, laboratory testing,
issue and transfusion of blood.
Area of documentation needed for developing data base
1. Donor records including details of donor information, rare donor
panels, donor deferrals and adverse donor reactions.
2. Record of results and interpretation of all laboratory tests.
3. Patient’s record (for all patients and specifically important in
patients with multiple transfusions, previous transfusion reactions,
presence of unexpected antibodies or cross-match problems).
4. Record of component preparation.
5. Inventory of blood, blood components, reagents and consumables,
etc.
6. Record of compatibility testing.
7. Record of discarded blood units.
8. Record of issue of blood.
9. Quality control record (which helps in taking corrective actions to
improve the performance of any procedure or working of any
equipment and reagents).
Blood screening.
Routine mandatory blood screening shall be done as per Safe Blood
TransfusionAct-2002. The following information should be stored:
• The sample number;
• The test results,
• Date and time test performed, identity of person(s) entering/
validating results,
• Technique used for performance of test
• Confidentiality of test results,
• Disposal positive/reactive samples.
Compatibility testing.
• ABO group red cell required special authorization.
• For components other than red cell it should be possible to
define criteria locally with regard to ABO and RhD acceptability.
• The system should allow a definable reservation period for
cross- matched units and produce a return to stock list. The
reservation date must not exceed the expiry date of the
components.
• The system should allow results to be entered against each unit
cross-matched. Whatever the method of entry the following
information must be stored.
Date and time test performed.
Identify of person (s) entering /validating results.
• After verification of results a compatibility report and labels must
be produced.
• The cross-match record should retain information on both
compatible and incompatible units.
• The facility should exist to allow the issue under password
control of ABO-compatible, but serologically incompatible units
in exceptional circumstances. All such units must be
appropriately labeled.
