Papua New Guinea Red Cross Blood Transfusion Service: present status and future considerations

Area of Science:

• Transfusion Medicine
• Infectious Disease Epidemiology
• Public Health

Background:

• Papua New Guinea collects approximately 28,000 blood units annually, meeting current demands.
• Recent data show an increase in human immunodeficiency virus (HIV) positivity among blood donors.
• Hepatitis B prevalence averages 15% among donors, with regional variations.

Purpose of the Study:

• To assess the current blood supply adequacy in Papua New Guinea.
• To evaluate the implications of increasing infectious disease markers in blood donors.
• To determine the need for expanded screening for additional pathogens.

Main Methods:

• Analysis of annual blood collection volumes.
• Review of human immunodeficiency virus (HIV) and hepatitis B screening results from blood donors.
• Assessment of established HIV transmission cases via transfusion.

Main Results:

• The current blood collection volume is sufficient for existing needs.
• Eleven donors have tested positive for human immunodeficiency virus (HIV) since 1987, with 8 cases in the past 1.5 years.
• No confirmed cases of HIV transmission through blood transfusion in Papua New Guinea have been reported.

Conclusions:

• While the blood supply is currently adequate, rising HIV and hepatitis B rates require attention.
• Future blood supply needs and the necessity of screening for hepatitis C (HCV) and cytomegalovirus (CMV) warrant careful evaluation.
• Strategic decisions regarding blood safety and expanded testing protocols are essential.
