COVID-19 Convalescent Plasma CCP Interdepot Transfer

drzeyd

This is a part of a continuing series of posts on the actual Medinfo design of the CCP donation and release processes and covers the transfer of completed units to the hospital blood banks.  It highlights specific changes made for the parallel CCP system I developed at HMC Doha.

A blood component is either located at a production site, a destination hospital blood bank site, or in transit.  Here a quarantine production site is specified.  The actual transfer protocols and allowable destination sites are listed for this product.

COVID-19 Convalescent Plasma CCP Thawing and Marker Testing

drzeyd

This is a part of a continuing series of posts on the actual Medinfo design of the CCP donation and release processes and covers CCP plasma thawing/labelling and donor marker testing.  It highlights specific changes made for the parallel CCP system.

Thus, the machine interfaces for testing are the same as for regular testing and are not included in this document. Likewise, donor immunohematology testing is the same as for regular donors and is not addressed here

COVID-19 Convalescent Plasma CCP Donor Questionnaire and Collection

drzeyd

This is a part of a series of posts on the actual Medinfo design of the CCP donation and release processes.  The site and donor registrations were covered in a recent previous post.

Donor Questionnaire and Physical Examination:

After registration, there is the online CCP donor questionnaire and vital signs entry.

Note that the CCP donor will automatically be excluded from other types of donation.  All other types will appear as contraindications in RED below.

Donor Apheresis Collection:

The actual donation process is the same as for plasmapheresis donors:

Specifications for the CCP Blood Bank-Hospital Information System Interface

drzeyd

At HMC Doha, we had a limited bidirectional interface between Medinfo Hematos IIG blood bank software donor and patient modules and the hospital information system HIS Cerner Millennium for blood component and limited blood bank testing ordering and return of the blood component ordering statuses and all blood bank test results.

For the purpose of COVID Convalescent Plasma CCP, the following specifications applied:

  1. Ordering of CCP was either by number of units (average 220 ml each) or volume in ml (up to 200 ml).
    1. Maximum order was 2 units.
  2. Only designated physicians could order CCP.
  3. A valid type and screen (72 hour maximal validity) had to be in effect to place an order for CCP.
    1. If not valid, a new type and screen must be ordered before ordering CCP.
  4. Selection of the ABO type of CCP was at the discretion of blood bank using its standard algorithms.
  5. Status of order (ordered, received in blood bank, in process in blood bank, or released) would show in the HIS.

Note:  Bedside documentation of the component transfusion was the NOT the responsibility of Transfusion Medicine or Medinfo Hematos IIG.

COVID-19 Convalescent Plasma CCP Donor Registration

drzeyd

I designed a completely quarantined process for collection, processing, and release of CCP at HMC Doha.  This document shows the Medinfo process for donor registration as a separate donor center code.

Check donor history and donor deferral database.  If there is no previous encounter, generate a new donor file:

At the completion of this action, the Blood Donation Record with the donor unit number (in this example 2200000099) and consent form in English and Arabic is generated.

CCP could only be collected at this special site and only the apheresis bag could be used for collection.  Regular donation options were not available at this CCP site nor was CCP collection an option at the regular donation sites.
