Patient Knowledge and Preferences Regarding Autologous Versus Allogeneic Blood Transfusion in Mpilo Maternity Ward

Abstract

Blood transfusion is a critical intervention in maternal healthcare, particularly during obstetric surgery and the management of haemorrhage. While both autologous and allogeneic blood transfusion options are available, patient knowledge, attitudes, and preferences play a key role in informed consent and patient-centred care. This study assessed expectant mothers’ knowledge, attitudes, and preferences regarding autologous versus allogeneic blood transfusion in the maternity ward at Mpilo Central Hospital, Bulawayo, Zimbabwe. A descriptive cross-sectional study was conducted among 44 expectant mothers using a structured questionnaire. Data were analysed using descriptive statistics and chi-square tests to assess associations between demographic variables and awareness of autologous transfusion. Most participants were aged 26 35 years (52.3%) and had attained secondary education (54.5%). Although general awareness of blood transfusion was high, only 18% of respondents had heard of autologous transfusion, and just 20.5% correctly defined it. The most commonly perceived benefit of autologous transfusion was reduced risk of infection (27.3%), while lack of knowledge was the most frequently cited limitation (36.4%). Despite limited knowledge, attitudes toward autologous transfusion were generally positive, with 61.4% willing to consider it if recommended by a healthcare provider and 54.5% perceiving it as safer than allogeneic transfusion. Overall, 56.8% of respondents preferred autologous transfusion. No statistically significant association was found between educational level and awareness of autologous transfusion (χ² = 1.27, p > 0.05). The study demonstrates significant knowledge gaps regarding autologous blood transfusion despite favorable attitudes and preferences. These findings highlight the need for targeted antenatal education and enhanced healthcare provider–patient communication to support informed decision-making and improve maternal transfusion practices.
