Data science pioneer Chinedu Nzekwe revealed that the country's healthcare distribution is flawed, with too many resources concentrated in wealthy urban areas while rural and low-income areas are underserved.
This disparity, he said, has resulted in underutilization of health resources in some areas and a shortage in others.
To address these issues, experts recommend leveraging machine learning (ML) algorithms to optimize healthcare delivery and resource allocation, transforming the healthcare landscape in Nigeria and Africa.
Machine learning is a subset of artificial intelligence (AI) – algorithms that can learn from and make predictions based on data. In healthcare, ML can enhance decision-making and service delivery across a range of disciplines. By recognizing patterns and insights from large datasets, ML algorithms can predict patient outcomes, optimize resource allocation, and improve overall healthcare efficiency.
Healthcare systems are vital to a nation's productivity and human capital formation. Therefore, implementing innovative approaches like ML can help minimize costs and improve the quality of healthcare services. Integrating ML algorithms can help stakeholders address key issues such as geographical distribution of resources, misallocation of resources, and inequality in access to healthcare.
Chinedu Nzekwe, a final-year PhD student in Applied Science and Technology majoring in Data Science and Analytics, emphasises the importance of this integration.
“Healthcare systems need to evolve to harness the power of data science and machine learning. These technologies can provide critical insights that improve resource allocation and improve patient outcomes,” Nzekwe explained.
He noted that the current uses and benefits of ML applications in healthcare are diverse and impactful.
These include predictive models for patient readmissions, disease outbreaks, and resource needs. These models can forecast the number of tests needed, predict delivery times for test results, and estimate future healthcare demand. For example, during the COVID-19 pandemic, ML models helped predict deaths and optimize testing strategies, demonstrating practical value in managing public health emergencies.
In Nigeria, ML can be used to address inequities in access to healthcare caused by an uneven distribution of healthcare workers and facilities. With a patient-to-healthcare worker ratio of up to 10,000 to 1 in some areas, ML can optimize healthcare facility placement and resource allocation to better serve underserved populations.
He says this optimization could lead to improved medical services and increased patient satisfaction.
“By analysing demographic, social and health service data, ML can better predict healthcare needs, which in turn allocates resources where they are most needed, improving the effectiveness of the overall healthcare system,” says Nzekwe.
Case Studies and Best Practices: Successful implementations of ML in healthcare highlight its potential to improve service delivery and outcomes. For example, dermatology has used ML models to diagnose skin lesions with high accuracy, in some cases outperforming human experts. In medical imaging, ML has improved the accuracy of diagnosing retinal diseases and bone density measurements, demonstrating its ability to handle complex diagnostic tasks.
Instead, he argued, the focus should be on developing actionable ML models – simulating outputs for experts to evaluate and validating the models with real data.
Training and capacity building: Invest in training healthcare professionals in ML techniques and foster interdisciplinary collaboration.
Create population-centric datasets: Develop comprehensive datasets that include demographic, clinical, and image data to support robust ML models.
Addressing ethical and privacy concerns: Ensure data privacy and ethical considerations in the development and deployment of ML algorithms.
He said these challenges require a multi-pronged approach, which includes infrastructure development – investment in data storage and processing capabilities to handle large medical datasets;
Policy and regulatory support: Establish policies that encourage data sharing and collaboration while ensuring data privacy and security.
Encourage partnerships between government agencies, healthcare providers, and technology companies to foster innovation and scale ML applications.
“One of the main challenges is the lack of adequate infrastructure to support the massive data requirements of ML algorithms,” Nzekwe points out.
“Investment in robust data storage and processing systems is essential to successfully implement these technologies.”
Integrating machine learning algorithms into Nigeria's healthcare system offers great potential to optimize healthcare delivery and resource allocation. By leveraging machine learning, Nigeria can address existing challenges, increase the efficiency of healthcare services, and ensure equal access to quality healthcare for all its citizens. Embracing these technological advancements, as experts recommend, will pave the way for a healthier and more prosperous future for Nigeria and Africa.
Nzekwe stressed that “the future of healthcare lies in our ability to harness the power of machine learning so that we can transform healthcare delivery and improve the lives of millions of Nigerians.”
