A Scoping Review: Short-term Experiences in Global Health Can Inform Approaches to the Provision of Care in Rural America

Imagine a world where the distance to a specialist doctor is measured not in miles, but in days of travel, and where the lack of a simple skin treatment can lead to long-term suffering. This is the reality for millions of people in resource-limited countries, and it is also the reality for many residents of rural America, where entire regions exist without a single dermatologist. For decades, medical professionals have traveled to these underserved areas to provide care, often in the form of short trips where teams of doctors and students set up temporary clinics. These efforts, known as short-term experiences in global health, were designed to bring immediate relief to those in need while teaching the volunteers about medicine in difficult settings. However, a growing body of thought suggests that while the intention is noble, the execution often falls short. When these trips focus more on the education of the visitor than on the long-term health of the host community, they risk becoming what critics call "poverty tourism," offering a fleeting fix that leaves the underlying problems untouched.

The question facing modern medicine is whether the lessons learned from these international trips can be applied to fix the healthcare gaps right here at home. A team of dermatologists and researchers from the University of Mississippi Medical Center and other institutions set out to explore this connection. They conducted a broad review of existing literature to identify the core principles that make short-term medical missions ethical, effective, and sustainable. Their goal was not just to list what works abroad, but to see if those same strategies could be adapted to solve the severe shortage of skin specialists in the rural United States. They found that the challenges are strikingly similar: whether in a remote village in Honduras or a small town in the Mississippi Delta, the barrier is the same—a lack of local expertise and the difficulty of maintaining care after the visiting team leaves.

The researchers identified five key pillars that turn a well-meaning but potentially wasteful trip into a force for lasting change. First, the focus must shift from simply treating patients during the visit to building the capacity of local providers. Instead of a team of outsiders performing procedures that no one else can do, the priority becomes teaching local nurses and doctors how to handle these cases themselves. This ensures that when the visitors depart, the community is left with stronger skills, not just a temporary fix. Second, the teams must work in true partnership with local institutions, rather than operating as independent entities. This means listening to what the community actually needs and aligning their efforts with existing local healthcare systems. Third, the care provided must be culturally competent, respecting local customs and language to ensure patients feel safe and understood. Fourth, the programs must be evaluated continuously to see what is working and what is not, allowing for constant improvement. Finally, and perhaps most importantly, every intervention must be designed with sustainability in mind, asking how the benefits will continue long after the funding runs out.

When the authors applied these principles to the situation in rural America, a clear path forward emerged. They pointed out that the United States faces a "dermatology desert" problem, where vast areas have no access to skin specialists. Just as in global health, the solution lies in moving away from the idea of a single, heroic visit and toward a model of integration and education. One successful approach involves setting up regular, scheduled "pop-up" clinics where specialists visit rural areas to see patients, but crucially, they work alongside local primary care providers. These local providers are then trained to manage follow-up care, creating a bridge that keeps the patient connected to the system. Another powerful tool is the use of technology, specifically store-and-forward teledermatology, where local doctors take photos of skin conditions and send them to specialists for advice. This allows a rural doctor to act as a specialist for their own community, expanding the reach of expert care without requiring the patient to travel hundreds of miles.

The paper also highlights the critical role of training the next generation of doctors. The authors noted that eight states in the U.S. currently have no dermatology residency training programs, meaning no new specialists are being trained to stay in those regions. To change this, they suggest creating specific training tracks for medical students who grew up in rural areas and want to return home. By training these students in rural settings and providing financial support for their education, medical schools can increase the likelihood that these doctors will choose to practice in underserved communities. The data from the University of Mississippi Medical Center supports this idea; their residency program has produced graduates who are now practicing in rural parts of the state, proving that targeted training can fill the gap.

Ultimately, the study concludes that the same strategies used to improve global health can revolutionize rural healthcare in America. The key is to stop viewing these efforts as temporary missions and start viewing them as long-term investments in local capacity. By focusing on education, partnership, and sustainability, medical teams can ensure that the care they provide today builds a foundation for health tomorrow. The authors hope that by adopting these proven principles, the United States can finally address the deep inequities in access to care, ensuring that a person's zip code does not determine the quality of their health. The path forward is not about sending more volunteers for short visits, but about building a system where local communities have the tools, the training, and the support to care for themselves.
