The intravenous (IV) drip rarely draws attention—it’s neither dramatic nor instant in its effect. But it transformed modern medicine by delivering exactly what the body needs in a form and at a pace the body can handle. Its impact lies in its precision, its steadiness, and its ability to sustain life when more aggressive or less direct interventions fall short.

Before the introduction of IV therapy, physicians relied on single-shot treatments: rapid injections, crude transfusions, and one-time interventions administered in the hope that speed would produce recovery. Those treatments rarely worked. The dosage was too large, the target too inexact, the pace too quick, and the result too often disappointing.

In 1832, as cholera spread through Edinburgh, Dr. Thomas Latta tried a new approach. He recognized that cholera caused severe fluid and electrolyte loss, and he infused a simple saline solution directly into the bloodstream. What set his method apart was not just the substance, but also the delivery. Instead of flooding the body with a fast, aggressive dose, he administered it slowly and steadily. The method worked. Patients stabilized more reliably, and physicians could begin treating dehydration and shock with greater precision and control.

The breakthrough wasn’t only the saline solution—it was how it was administered: in small, steady doses infused directly over time. It marked a shift away from one-time interventions and toward sustained, controlled support.

In the years since, IV therapy has become essential. It underpins the treatment of trauma, infection, cancer, and post-surgical recovery. By delivering care directly into the bloodstream, it allows health care teams to monitor response, adjust in real time, and create stability where there was once chaos. IV therapy succeeded not by doing more, but by responding with intention, pace, and precision.

You may be wondering why a business journal article just gave you a brief history of 19th-century drug delivery. I bring it up because the shift Dr. Latta pioneered—from single-dose shock to sustained care—is one that many large organizations have yet to make. Having worked alongside health care leaders for years, I have seen firsthand how the most effective interventions, whether clinical or cultural, are rarely sweeping. They are deliberate, repeated, and built for absorption.

Change does not stick because it was eloquently stated. It sticks because it was well delivered.

In health care, we don’t expect a single injection to treat a complex condition. When the stakes are high, treatment is given through a steady drip. Not because people can’t handle more, but because their systems are not built for sudden disruption. The same should be true for organizations. But it often is not. Too many leaders communicate once, then move on. No pacing. No monitoring of feedback. No reinforcement. That is not a strategy; it is guesswork. If change really matters, it deserves the same level of care we bring to medicine. You calibrate the dosage, monitor the effects, and remain willing to adjust.

Change isn’t mechanical. It’s biological—it’s human. And humans don’t leap from awareness to adoption because something was announced. We need time to hear it, space to question it, and reason to believe it. This takes time, trust, and a willingness to meet people where they are. A good treatment plan builds in continuous engagement. One message isn’t enough.

The most effective care plans for complex conditions are rarely the fastest or loudest. Rather, they’re the most precise.

That mindset rarely carries over to how organizations deliver change.

Instead of designing for absorption, many teams default to announcements. Leaders push out a message, hold a launch meeting, and move on. But if you look at where treatment breaks down in medicine, you’ll see the same patterns show up in transformation and culture work.

Where It Breaks Down

The failure is not one of intention; it is one of design. We assume that if something was said clearly, it must have been understood. If it was delivered confidently, it must have landed. But clarity and persuasion are not the same thing. Awareness does not equal adoption.

What Works in IV Drip Treatment—and What We Can Apply in Culture and Transformation

Don’t treat communications like a box to check. Treat them as part of the intervention. What matters isn’t how often you speak, but whether your message is absorbed and moves people from awareness to understanding, and ultimately to action.

A few principles follow:

Say it more than you think you should.
Even if it feels repetitive to you, it probably doesn’t for them.

Stop assuming “said” means “understood.”
People need to hear it, question it, believe it, and try it.

Build long-term messaging arcs, not one-time events.
If the change takes months, your messaging should too.

Measure outcomes, not output.
It’s not about what was delivered. It’s about whether it was effective and led to adoption, engagement, and belief.

Monitor how it’s landing. Adjust when needed.
If it’s not getting through, don’t blame the message. Consider the messenger, timing, format, or delivery method, with a willingness to shift.

Create space for dialogue.
Host office hours. Invite questions. Listen to what you hear.

Anchor to purpose. Revisit it often.
Health care providers return to their oath when uncertain, to treat the sick and do no harm. Do the same with purpose, and let it guide the change.

Let guiding principles guide.
Just like clinicians use protocols to stay grounded in best practices, use guiding principles to shape choices, frame tradeoffs, and offer a clear test for what to do next, especially when the situation is complex or evolving.

Consider the full differential.
If change isn’t sticking, don’t stop at the first symptom you see. Step back and examine all possible contributors: timing, trust, delivery method, competing priorities, or change overload. Diagnose before you prescribe.

Dr. Latta’s work wasn’t widely adopted in his lifetime. It was overlooked, imperfect, and slow to gain recognition. But it saved lives. In hindsight, it marked a turning point that reshaped modern care. The same may be true for how we deliver change. A steady message, repeated with care, might not feel novel or urgent in the moment, but it’s how trust is built and culture takes root. What starts as communication becomes the lifeblood of transformation. And in time, we may look back and realize this small shift in mindset and method changed far more than we expected.

Just like when you walk into a hospital room, you may not notice the IV, the monitors, or the pre-planned care protocols. But they’re there: quiet, steady, intentional. They have become expected and keep the system stable. Change sticks because it was well delivered.

Plan it. Pace it. Monitor it. Adjust it.
