Most people who use modern health systems also use traditional healing systems. The interface between them is managed poorly or not at all.
The Dual System Reality
In most of the world, modern biomedicine coexists with traditional healing systems — the accumulated practices of communities for managing illness and maintaining health that predate and persist alongside the modern health system. The typical official response to this dual system reality is denial: the formal health system acts as if the traditional system does not exist, does not integrate with it, and frequently positions itself in implicit competition with it. This denial is institutionally convenient but practically harmful. The patient simultaneously receiving treatment from both systems — which a large proportion of patients in many societies are — receives no coordination between the two, with the result that treatments may interact harmfully and the formal health system has no information about the treatments the patient is receiving from the traditional one.
The Integration Challenge
Managing the traditional-modern interface constructively requires the formal health system to acknowledge its existence, to develop clinical frameworks for understanding which traditional practices are beneficial, which are neutral, and which are harmful, and to build the communication systems that allow formal and traditional health workers to coordinate on shared patients. This requires cultural humility — the willingness to engage with traditional systems as legitimate providers of some health services rather than as competitors to be displaced.
The traditional-modern health interface exists whether or not the formal health system acknowledges it. Patients navigate it alone, without the coordination that would make their navigation safer. The health system that denies the interface's existence has decided that its institutional tidiness matters more than its patients' actual health behaviour.
