In an insightful new book, titled "Decolonizing Healthcare Innovation: Low-Cost Solutions from Low-Income Countries," Dr. Matthew Harris highlights the importance of learning from low-income countries in order to enhance healthcare systems in high-income countries. Reflecting on his experience working as a family doctor in Brazil and his subsequent return to the United Kingdom, Dr. Harris emphasizes the need for open-mindedness and the challenges of overcoming prejudice in the medical field.

Upon returning to the U.K., Dr. Harris encountered what he describes as a "wall of prejudice" regarding his ideas inspired by the Brazilian health system. Despite being both an insider and an outsider, being a U.K. born and trained clinician and a Brazilian doctor simultaneously, he witnessed an unwillingness to fully consider the opportunities presented by the Brazilian system. This experience gave Dr. Harris a sense of injustice and empathy for researchers and clinicians from the Global South whose valuable insights often go unheard due to prevailing prejudices in global health.

One key aspect that Dr. Harris urged the National Health Service (NHS) to consider was the adoption of a community health worker model, which forms the foundation of the Brazilian primary-care system. After two decades of persistence, the U.K. has finally introduced the community health worker role, now successfully scaling throughout the country. These workers cover small geographies, build trust, and provide comprehensive healthcare activities, ultimately integrating individuals into primary care. Examples from countries such as Brazil, Ethiopia, and India demonstrate the effectiveness of a coordinated community health workforce in delivering long-term health and social care support on a larger scale.

Dr. Harris acknowledges the objections initially raised against the implementation of such a system, which he argues were unsupported beliefs rather than rooted in factual evidence. These objections ranged from concerns about privacy and cost to claims of cultural differences. However, time and experience have shown that these objections were unfounded, as community health workers have proven to be proactive in promoting health, cost-efficient when implemented at scale, and adaptable to various cultural contexts.

The book also delves into the concept of a "hidden curriculum" in global health institutions, where Western sources of knowledge are prioritized, perpetuating a biased worldview that disregards research from other geographical regions, including the Global South. Dr. Harris emphasizes the importance of recognizing and challenging this bias and promoting the inclusion of diverse sources of knowledge within medical education.

Furthermore, Dr. Harris explores the concept of frugal innovation, wherein low-income countries maximize their resources to achieve efficient healthcare outcomes. He highlights examples such as the use of mosquito net fabric in hernia surgery in India and the utilization of tilapia fish skin for treating burns in Brazil's Amazon region. These cost-effective solutions deliver outcomes comparable to expensive alternatives, highlighting the value of embracing innovative approaches from low-income countries.

In conclusion, Dr. Matthew Harris's book sheds light on the vital lessons that high-income countries can learn from low-income countries to revolutionize healthcare systems. Through a combination of soft reforms, such as diversifying sources of knowledge, and radical reforms that challenge existing Western-centric models, a more equitable and effective global health knowledge ecosystem can be established. Dr. Harris emphasizes the importance of collaborations, partnerships, and the recognition that everyone has something to contribute to the evolution of healthcare worldwide.

While progress has been made, Dr. Harris believes that earlier recognition of the potential of learning from the Global South could have led to significant advancements in healthcare systems. The book serves as a powerful call-to-action for healthcare professionals and policymakers to prioritize listening, learning, and embracing innovative approaches from around the world.
