Theory of Change: #22: AI and the humanity of health care
For decades, international development has gravitated toward tangible interventions that produce quantifiable results: Specialized clinics, diagnostic machinery, donated pharmaceuticals, and targeted vertical programs designed to eliminate specific diseases.
Yet the most sophisticated medical supplies remain useless without trained personnel, as Seed Global Health CEO Dr. Vanessa Kerry points out.
“Shots don’t put themselves in arms,” Kerry said on Devex’s Theory of Change podcast. “You can put as much tech or as many medicines as you want into a system, but if you don’t have someone to deliver them, the system falls apart. You need someone to catch a baby; you need someone to hang a bag of blood.”
Kerry outlined a critical bottleneck across global development: While sub-Saharan Africa shoulders roughly a quarter of the global disease burden, it commands barely 3% of the world’s health workforce.
Kerry traced her own realization of this imbalance back to her medical training in Rwanda, where an unattended, complicated birth threw the stark absence of frontline skilled personnel into sharp relief. That formative episode inspired her to create Seed Global Health, an organization dedicated to long-term partnerships with governments to train doctors, nurses, and midwives along national priorities rather than temporary donor whims.
Today, global health is facing a series of compounding crises.
Accelerating climate shocks, emerging epidemics, and sweeping bilateral aid contractions threaten to roll back decades of hard-won progress. Yet Kerry, who was recently appointed WHO director-general’s special envoy for health resilience, argued that prevailing development models continue to repeat the mistake of fragmentation.
Donors routinely earmark billions separately for pandemic preparedness, noncommunicable diseases, and climate adaptation, without recognizing that all three initiatives rely on the exact same clinical staff, laboratories, and supply chains.
Kerry called for a shift toward systemic resilience, underpinned by country ownership. Instead of forcing finance and health ministries to juggle dozens of disjointed bilateral programs and competing reporting frameworks, Kerry argues donors must rally around a streamlined principle: “One health plan, one budget that aligns to that health plan, and one reporting metric.”
In Uganda, this country-led approach to emergency medicine and triage training has cut the 24-hour mortality rate in emergency rooms by nearly 40%, Kerry said.
As Silicon Valley heralds artificial intelligence as a potential leapfrog tool for low-resource health delivery, Kerry pushed for a vital dose of frontline reality. While AI algorithms and portable diagnostics hold genuine promise to empower clinicians, technology remains a multiplier — not a substitute.
“You can’t multiply by zero,” Kerry warned. “If we don’t have the fundamental infrastructure and pieces in place ... it doesn’t matter how fast AI can take us. You need to have a health care worker that is holding the ultrasound.”
Beyond clinical logistics, Kerry insisted that compassionate care in moments of terror or bereavement remains an irreplaceable human transaction.
