Meet Dr Kerry Vaughan, a brain surgeon's global network
For 27 years, many remarkable people have stepped through our doors and left changed. This month, we want you to meet one of them.
Dr Kerry Vaughan is a paediatric and adult neurosurgeon at the Barrow Neurological Institute in Arizona, one of the world's largest neuroscience programmes. Her global health journey began during her residency, when she took a research placement in Uganda.
"I got the opportunity to start as a resident when I was training in neurosurgery, and heard there were a lot of people in global surgery and anaesthesia doing this work, even some neurosurgeons. So, my programme chairman allowed me to go work in Uganda during my training, for research, to get to know what global health is and get a different experience."
That experience challenged the assumption that highly specialised neurosurgery can only exist in major Western hospitals. Today, through Barrow Global and the G4 Alliance, she works alongside a worldwide network of surgeons, including Richard Henker, AHC's anaesthesia unit mentor.
But the real currency of that network is not procedures, it is trust. That closeness allows teams to solve problems in real time, across continents.
"These people become like family or friends. We call each other by family terms because we grow so close when we work so much with teams over time. If one of us has a question or an interesting case, talking about it over WhatsApp, phone calls, Zoom, we can problem-solve all together around the world."
Perhaps most striking is her belief that neurosurgery, a field often associated with expensive technology, does not always require it for its most important cases.
"There's a lot of common and important neurosurgical cases that are needed around the world that can be done with not that much technology. If we don't have a navigation system, we can use ultrasound instead. Start with the basics, what's feasible, and build up piece by piece."
That resourcefulness feeds into a broader ambition: turning frontline clinical experience into international policy. Through the G4 Alliance, she has helped advance resolutions through the WHO’s World Health Assembly, including one this year on nutrition to help prevent conditions such as spina bifida. She is now working on a resolution encouraging governments worldwide to commit to tracking and treating traumatic brain injuries.
Her connection with AHC began with a specific challenge: too many trauma cases, too many head injuries, and no clear guidance on which children could be safely monitored and which required transfer.
"Dr Farrilend (AHC surgeon) had drafted a protocol for dealing with head injuries in children at AHC, and asked if I could give some expert insight on it. It's perfect, because they really want this to grow, and if I can provide some support, hopefully it's a good partnership."
But when she arrived, she found something that went beyond the clinical need that first brought her to AHC: the strength of the team culture.
"What's struck me at AHC is how well people work together. The theatre team communicates well between nursing staff, anaesthesia staff, and surgeons, and makes sure every voice is heard and respected. It's really impressive."
She is leaving with as much as she came to give, taking ideas from AHC's theatre setup back to her own hospital and to Barrow's partner site in Tanzania. For Dr Vaughan, global health is not about an outside specialist arriving with all the answers. It starts with listening.
"I've seen some amazing teamwork here at AHC, and uses of technology in the theatre, that I'm hoping to bring back to the US and Tanzania. There's learning in both directions, and the main thing is making sure it's helpful for the local team. I always try to ask, what would be helpful for you? What do you want to see growing in your hospital? I try to support that, and if I don't know, the network of people we know around the world can help."
