Processes and Software Building: Profile Cards 1-2-3 for Extended Antigen Typing

drzeyd

This is an update of a previous post.

In any case with nonspecific antibodies and for all new patients who will require chronic transfusions, I perform extended Rh (CcEe)/Kell and the three Diamed (now Biorad) profile cards.

It is very easy in Medinfo to write a process for any group of antigen typings as long as you know the manufacturer’s criteria for accepting results.  Some cards have controls, others do not.  In the latter case, the “control” is a negative reaction in the card or series of cards of the same type.

In Medinfo, one can also look for errors in using the card:  In Profile Card 3, i.e. the MNSsFyaFyb card, one must reject the card if no reactions in any well appear:  Did the technologist forget to add the cells or reagents?  Did he/she use the wrong diluent (i.e. bromelin enzyme) which would destroy the labile antigens?

One can set the acceptable range of reactivity, flag for mixed field, etc. and record these findings in the official record.  One can define which reactions you will accept an automatic reading of the card.  For the other readings, one can force a manual review and result entry.

Note that Profile Cards 1 and 2 both have an internal control whereas Profile Card 3 (enzyme-labile antigens) does not.

Here are the processes for all three profile cards:

Policy: Division Head Transfusion Medicine Role in Policy Making

drzeyd

Principle:

The Division Head, Transfusion Medicine and Blood Banks, is responsible for all aspects of transfusion medicine at HMC for the State of Qatar.  The following policy documents some of those roles.

Policy:

  1. The Division Head, Transfusion Medicine HTM, serves as a member of the Corporate Transfusion Committee
  2. The HTM through the CTC establishes criteria for transfusion of blood components and passes these through the HMC corporate process for establishing official guidelines.
  3. The HTM reviews blood component requests, especially in times of shortage to triage in conjunction with the Medical Director and Chairperson, DPLM
  4. The HTM establishes transfusion practices through the interim policies, which are in turn used to prepare processes and procedures through corporate transfusion medicine.
  5. The HTM serves as Project Manager for the Medinfo Hematos IIG computer system and prepares policies, processes, and procedures for Transfusion Laboratory Information Systems.

Process: Interdepot Transfer

drzeyd

Enumeration:  5.9.1

Process:

  1. All transfers of blood components will be done through the dedicated blood bank computer system Medinfo Hematos IIG.
  2. Ensure that the final ISBT label is attached.
  3. Each unit must have a final ISBT label attached.
  4. Prepare a consignment list for the units to be transferred.
  5. Transfer the units in temperature controlled and monitored, validated containers.
  6. Upon receipt at the destination, check the temperature log or liquid crystal sticker to confirm the unit(s) have been maintained at the proper temperature.
  7. Upon receipt at the destination, repeat the ABO forward and D type of the transferred RBC units and the reverse type of the plasma units.
  8. Subsequent transfers between hospital blood banks do not require repeat ABO/D typings.
  9. Inspect each unit for leaks and physical appearance (e.g. clots, leaks, discoloration).
  10. Enter the new stock into the local hospital’s inventory.
  11. Use the specific transfer algorithms programmed into the Medinfo Hematos IIG software.
  12. All variances will be reviewed by the supervisor and a transfusion medicine physician.

Policy: Interdepot Transfer

drzeyd

Enumeration:  5.9

Policy:

  1. All transfers of blood components will be done through the dedicated blood bank computer system Medinfo Hematos IIG.
  2. Only units passing all donation criteria including testing and processing will be eligible for transfer.
  3. Each unit must have a final ISBT label attached.
  4. Quarantined units will be discarded through Medinfo at the blood processing site.
  5. Units will be transferred in temperature controlled and monitored, validated containers.
  6. Upon receipt, the ABO forward and D type of the transferred RBC units will be repeated at the first hospital blood bank.
  7. Subsequent transfers between hospital blood banks do not require repeat ABO/D typings.
  8. Each unit will be inspected for leaks and physical appearance (e.g. clots, leaks, discoloration).
  9. Only units whose temperature monitoring passes criteria for transit shall be used.
  10. The specific transfer algorithms will be programmed into the Hematos IIG software.
  11. All variances will be reviewed by the supervisor and a transfusion medicine physician.
  12. All policies, processes, and procedures must comply with Qatari, HMC, and applicable accreditation standards (i.e. AABB, CAP, and JCI).

Policy: Component Processing

drzeyd

Enumeration:  5.8

Policy:

  1. All processing will be in accordance with good manufacturing practices.
  2. All testing will follow manufacturer’s recommended testing methods.
  3. The specific processing algorithms will be programmed into the Hematos IIG software.
  4. Validation of the processing will be performed by Hematos IIG, which will control final ISBT labelling
  5. All abnormal results will be reviewed by a transfusion medicine physician.
  6. All policies, processes, and procedures must comply with Qatari, HMC, and applicable accreditation standards (i.e. AABB, CAP, and JCI).

Process: Donor Notification of Abnormal Results

drzeyd

Enumeration:  5.8.2

Principle:

AABB requires that all donors be notified and counseled of abnormal test results in a timely manner.  Notifications should be done based on required AABB and/or CE protocols including the requirements for follow-up testing at specified intervals.

Process:

  1. Blood components prepared from donors with abnormal blood results will be discarded according to current SOPs unless a variance is approved by a transfusion medicine physician.
  2. Abnormal results will be handled according to the current Abnormal Marker Testing Algorithm in effect.
    1. Additional testing after specified time intervals may be necessary depending on the initial results.
  3. Medinfo Hematos IIG will automatically follow the donor marker testing abnormal result algorithm and quarantine the affected units.
  4. All abnormal test results will be reviewed by the Division Head, Transfusion Medicine or other Transfusion Medicine Physician in a timely manner upon completion of the testing algorithm and any other additional testing that has been ordered.
  5. A Transfusion Medicine physician will counsel the affected donor.
  6. Counseling will only be performed when the ALL specified test results are available.
  7. Donors will be counseled as soon as possible but within 8 weeks of completion of the test algorithm.
    1. All counselling must be done confidentially.
    1. A letter for the donor explaining the contraindication will be prepared and given to the donor at the time of the counselling session.
    1. Positive identification of the donor must be confirmed before counselling or releasing any results.
    1. If the donor cannot be contacted, details of the contact attempts will be added to the donor’s records in Medinfo Hematos IIG.
  8. Donors will be offered referral to the appropriate clinic (e.g. Infectious Disease) for treatment and/or further assessment.
