What Health Equity Advocates Could Learn From Drug Sales Reps

Somewhere in America right now, a person is going hungry while sitting two blocks from a food bank. Somewhere else, an older adult is falling in their home because no one ever told them about a free falls-prevention class down the street. These aren't failures of imagination. The programs exist. What's missing is the connective tissue between the person who needs help and the system that could provide it.

That gap costs lives. And oddly enough, one of the most effective models for closing it may come from an industry that health advocates rarely admire: pharmaceutical sales.

For decades, drug companies have sent representatives into doctors' offices to talk, one on one, about specific medications. It's a practice called detailing, and it works. So well, in fact, that the industry spends over $5 billion a year on it, according to a study published in JAMA. That kind of spending doesn't happen on a hunch. It happens because repeated, personal, tailored conversations change what doctors write on a prescription pad, again and again.

Health equity work, by contrast, has struggled to produce the same staying power. Population health programs and social needs initiatives often launch with good intentions and solid evidence behind them, only to fade because frontline teams never fully adopt the behaviors needed to make them work. Dr. Rishi Manchanda, founder and CEO of HealthBegins, argues that this isn't a failure of the ideas themselves. It's a failure of delivery.

Manchanda separates the method from the motive. Pharmaceutical companies have long faced criticism for blurring the line between medically necessary drugs and simply profitable ones. That criticism is fair and well documented. But the mechanics they used to change clinician behavior, the structure of detailing itself, are not inherently tied to profit. They're tied to psychology. And psychology can be borrowed for better ends.

Why Health Equity Programs Stall

Ask any clinician why they don't refer more patients to community programs, and the answer rarely involves malice or indifference. It usually comes down to time, and to trust.

Doctors are stretched thin. Identifying a patient who might benefit from a diabetes prevention program, a falls-prevention class, or food assistance takes time most clinicians don't have in a fifteen-minute visit. It gets harder still when that patient is already dealing with unmet needs like food insecurity, which can make both diagnosis and follow-through more complicated.

There's also a relationship problem. Clinicians tend to know other clinicians. They don't usually know the program manager at the local YMCA or the caseworker at the Area Agency on Aging. Yet these community organizations run programs that address the upstream, non-medical factors that research suggests shape up to 80% of a person's health outcomes, according to a study published in the National Library of Medicine's PubMed Central database. Housing, food, transportation, social connection: these forces often matter more than anything that happens inside a clinic. But without a working relationship between the clinic and the community organization, referrals never happen. The program sits unused. The patient never walks through the door.

This is precisely the kind of gap detailing was built to close, just for a different purpose. The practice dates back to the 1800s, but modern pharmaceutical detailing took off in the 1940s. By the 1960s it was standard industry practice, with roughly 20,000 sales reps nationwide known as "detail men" for the way they delivered focused, educational pitches about specific drugs directly to doctors, according to a 1966 New York Times report.

Others have since adapted the model for public good. In the 1980s, Harvard researchers developed "academic detailing," sending nurses and pharmacists to physicians with unbiased, evidence-based information meant to correct rather than promote prescribing habits. Years later, the New York City Department of Public Health used a similar approach to push preventive care and disease management practices in neighborhoods with the highest mortality rates. The tool has already proven it can serve public health goals. It's just rarely been pointed at the specific problem of connecting patients to community resources.

Manchanda calls his approach "community health detailing," and he lays out four pillars for how it should work.

The first is a focus on specific behavior, not general awareness. It's not enough to tell a care team that food insecurity matters. You need to define the exact action you want them to take, whether that's asking a screening question, making a referral, or helping a patient enroll in a benefit.

The second is trusted messengers. Community health workers, peer educators, and people with lived experience carry a kind of credibility that a glossy brochure never will. They understand, firsthand, the barriers patients actually face.

Third, changes need to be small and repeatable. Care teams already juggling too much are far more likely to adopt a simple habit, like "screen, assess, refer," than a sweeping new protocol. Repetition, delivered in brief interactions over time, is what makes the behavior stick.

Fourth, referrals depend on relationships, not directories. A clinician will send a patient to a food pantry or a housing program only if they trust that the receiving organization will treat that patient with competence and dignity. A binder full of phone numbers doesn't build that trust. Ongoing contact does.

Why It Matters

The stakes here go beyond efficiency. Health plans, hospitals, and public agencies have already spent real money building programs meant to prevent disease and address the social conditions that drive poor health, from diabetes prevention to transportation assistance to Medicaid re-enrollment support. When those programs never reach the people who qualify, it's not just wasted funding. It's a missed chance to keep someone healthy before a crisis lands them in the emergency room.

That waste is harder to justify now than ever. Public health programs, healthcare coverage, and nutrition benefits are facing broad cuts across the country. Every dollar already invested in a working program needs to reach the people it was designed for. Detailing offers a tested, unglamorous way to do that: not through new spending, but through better relationships and better habits, built one conversation at a time.
