This study evaluated a program to notify pediatric patients transfused before routine HIV and hepatitis C virus screening. The notification prompted many unaware patients to seek testing, supporting such programs.

Area of Science:

  • Public Health
  • Transfusion Medicine
  • Patient Safety

Background:

  • Blood transfusions before 1985 (HIV) and 1990 (hepatitis C virus) carried risks due to lack of routine donor screening.
  • Identifying and notifying at-risk pediatric patients is crucial for public health and patient well-being.

Purpose of the Study:

  • To describe the notification process for pediatric patients who received blood products before viral marker screening.
  • To evaluate the effectiveness of this notification program in promoting patient awareness and testing.

Main Methods:

  • Medical and Transfusion Medicine Laboratory records identified pediatric patients (≤16 years) transfused between 1978-1985.
  • Patients were notified via registered mail, with a questionnaire assessing awareness and testing plans for HIV and hepatitis C virus.

Main Results:

  • 1546 patients were notified; 33.8% of letters were undelivered.
  • Of 493 respondents, 31.8% were unaware of their transfusion.
  • Notification prompted 69.4% to test for HIV and 89.7% for hepatitis C virus, though some reported anxiety.

Conclusions:

  • A significant proportion of patients were unaware of past transfusions.
  • The notification program effectively encouraged testing for HIV and hepatitis C virus, underscoring its value.
  • Notification programs are vital for managing risks associated with historical blood transfusions.
