Too much of a good thing?

What if telehealth kills the system it is meant to support?

We’re seeing two major trends shaping rural emergency care in smaller towns. The first is the effort to build local capacity by training more rural generalists and emergency practitioners. The second is the push to support clinical care when local staffing is stretched, by using telehealth to bring specialist expertise into the department remotely.

But we now have to ask a difficult question: what if one of these strategies is unintentionally undermining the other? What if telehealth — which we asked for, supported, and genuinely needed — ends up replacing rural clinicians rather than supporting them, contributing to the gradual disappearance of the on-site workforce it was meant to protect?

This isn’t the intention or fault of telehealth providers. It’s a pattern that can occur whenever a new technology arrives with enthusiasm and rapid uptake. In the early phase, we see only the upside — better access to advice, reduced isolation, fewer overnight call-ins — while the downsides remain invisible until much later. This dynamic is captured by the Gartner Hype Cycle: technology trigger → inflated expectations → disillusionment → recovery → stable productivity.

But by the time its limitations become visible — declining local clinical confidence, reduced tacit knowledge exchange, and increased pressure on nurses to make complex judgement calls — the on-site workforce may already have slipped below a critical threshold, making recovery extremely difficult.

A recent paper by Australian researcher Sagda Osman applied this conceptual framework to clinician-to-clinician telehealth in rural emergency care. The authors created a formal system dynamics model that simulates staffing over time, incorporating a key asymmetry: the benefits of telehealth are recognised quickly, while its limitations only reveal themselves gradually. Uptake accelerates early; attrition of on-site clinicians happens quietly, often unnoticed at first.

They ran 75 simulated scenarios of telehealth implementation. In about 85% of them, the rural on-site workforce declined past a point of no return. Telehealth stepped in to fill gaps — but then became almost the only mode of care. Only 15% of scenarios led to a stable coexistence of telehealth and strong on-site staffing.

The model identifies vulnerability conditions. Systems that start with very small on-site teams are fragile. Systems that embrace telehealth with uncritical optimism — believing it will fix everything — are fragile. The key point is that the danger isn’t telehealth itself. It’s the dynamic of rapid uptake combined with slow recognition of unintended consequences. And every intervention has unintended consequences.

So what does this mean for rural researchers? The model offers a testable hypothesis — now we need to examine whether it holds in practice. Do sites with heavy telehealth use see higher attrition of rural doctors? Do conservative telehealth adopters preserve stronger on-site presence? What happens when rural doctors themselves participate in telehealth provision? Are there communities where telehealth genuinely boosts confidence and recruitment? And where does the opposite occur?

We now have the opportunity to identify which implementation strategies strengthen the rural workforce — and which unintentionally weaken it. If we can understand that difference, telehealth can become what it was intended to be: a stabilising network of support that strengthens, mentors, and retains rural clinicians — not a substitute system that slowly makes them disappear.
