Development of a medical expert system to improve the quality of antenatal care in Tanzania
A Dissertation Submitted in Partial Fulfilment of the Requirements for the Degree of Master’s in Information and Communication Science and Engineering of the Nelson Mandela African Institution of Science and TechnologyMaternal mortality remains a global problem, with approximately 830 women dying every day
as a result of childbirth and pregnancy complications. The maternal mortality ratio is as high as
524 deaths per 100 000 live births in Tanzania. The main causes of maternal mortality in
developing countries are all linked to poor prenatal care, which is partially caused by treatment
delays. Studies show that providing women with maternal health information can help achieve
the goal of reducing global maternal mortality to less than 70 maternal deaths per 100 000 live
births by 2030. Through Natural Language Processing (NLP), we leveraged the use of BERT
question and answer model which is a pre-trained model that wasfine-tuned to develop a model
that can diagnose pregnancy complications, explain possible causes in simple language, and
provide recommendations for care and treatment, for Malaria, Pregnancy hypertension (Pre eclampsia), and miscarriage (Threatened abortion) which are the main preventable causes of
maternal mortality in Tanzania. The expert system is embedded in a maternal smartphone app,
MamaApp, that provides weekly information on fetal development, regular and concerning
pregnancy symptoms, and self-care tips. The expert system model was able to diagnose the
three conditions with confidence ranging from 79% to 100%. Validation of MamaApp in
Arusha showed high acceptance from both the expectant mothers and doctors
Maternal knowledge-seeking behavior among pregnant women in Tanzania
This research article was published by SAGE Publications Ltd, 2021Background:
Maternal mortality continues to be a global challenge with about 830 women dying of childbirth and pregnancy complications every day. Tanzania has a maternal mortality rate of 524 deaths per 100,000 live births.
Objective:
Knowing symptoms associated with antenatal risks among pregnant women may result in seeking care earlier or self-advocating for more immediate treatment in health facilities. This article sought to identify knowledge-seeking behaviors of pregnant women in Northern Tanzania, to determine the challenges met and how these should be addressed to enhance knowledge on pregnancy risks and when to seek care.
Methods:
Interview questions and questionnaires were the main data collection tools. Six gynecologists and four midwives were interviewed, while 168 pregnant women and 14 recent mothers participated in the questionnaires.
Results:
With the rise in mobile technology and Internet penetration in Tanzania, more women are seeking information through online sources. However, for women to trust these sources, medical experts have to be involved in developing the systems.
Conclusion:
Through expert systems diagnosis of pregnancy complications and recommendations from experts can be made available to pregnant women in Tanzania. In addition, self-care education during pregnancy will save women money and reduce hospital loads in Tanzania
