Factors associated with failure to disclose complete information regarding transfusion-transmissible infections among blood donors in Lahore, Pakistan.

Abstract

Background and objectives: This study aims to address the gap in understanding the factors associated with the non-disclosure of complete information by blood donors in Lahore, Pakistan.

Materials and methods: This was a cross-sectional study, conducted from February to April 2024. The study involved interviewing transfusion-transmitted infection (TTI)-positive blood donors from three large hospitals in Lahore. A validated questionnaire was used to analyse the factors associated with non-disclosure of information by these donors.

Results: A total of 25,155 blood donors were screened, of whom 1048 tested positive for TTIs. Among these, 218 participated in the study. The majority of them (92%) reported being unaware of their infection. Among those who were aware of their infection but still proceeded with blood donation, the primary reasons for the non-disclosure of infection status included a lack of seriousness, inadequate interviewing by blood bank staff and overcrowded interview areas. A significant proportion of TTI-positive donors reported uncertain sources of infection (47%), while others reported high-risk behaviours such as interaction with sex workers (34%) and blood transfusions at unauthorized clinics (7%). Future disclosure attitudes varied, with 22% preferring to keep their status confidential. Significant correlations were found between future non-disclosure and factors such as age, marital status, education, socio-economic status and number of blood donations.

Conclusion: These findings emphasize the need for targeted interventions to improve donor screening and pre-donation interview protocols. The study suggests the potential use of adequate counselling and provision of appropriate interview sites to reduce non-compliant behaviour and ensure safe blood donation practices.
