"Real-time." “Business rules.” "Clinically triggered." "In the workflow."
These terms have become familiar in EHR physician targeting, reflecting a growing interest in making pharmaceutical messaging more responsive to the circumstances and setting of patient care. And for good reason. Connecting brand information to the clinical context in which it's useful is one of the EHR channel's greatest strengths.
But not every approach described as "triggered" actually responds to the patient chart a physician is reviewing. This is especially true in multi-criteria programs, where a series of clinical criteria (sometimes called business rules) is stacked to target a highly specific patient profile, and largely due to the limitations of that specificity.
The more criteria in play, the fewer chart matches are likely to be triggered, and this challenge is amplified by differences in how various EHR systems enable and allow messages to be targeted. The result can be limited reach, impressions, or frequency. A vendor may be able to demonstrate that multiple clinical criteria can be evaluated together within an EHR. But that doesn't necessarily mean those same criteria can be activated across every system in its network, or that enough qualifying encounters will occur to meet campaign goals. The ability to trigger a message and the ability to deliver meaningful reach against those triggers are two different considerations.
For a narrowly focused campaign, those limitations may be acceptable. But for brands with broader engagement goals, such as a second-line therapy looking to reach physicians treating progressing patients or a brand raising awareness of formulary and access changes, insufficient reach can undermine campaign performance.
Does that mean triggered programs are only for niche populations? Not at all. But it does mean marketers need to look more closely at how triggered campaigns achieve both precision and scale, the relationship between EHR chart triggers and claims-based triggers, and the data that actually determines when their messages are delivered.
What Are Clinical Triggers in EHR Physician Targeting?
Clinical triggers activate in response to the presence of one or more clinical data points, such as ICD-10 codes, NDC, patient demographics, or specific combination of these and other data. In other words, triggers are predefined conditions that initiate message delivery when those specific criteria are present.
To use one of the examples above, a brand trying to be the second-line therapy of choice may want to target physicians treating patients that are likely to progress from the first-line standard of care, and use a combination of ICD-10, NDC, and indicators of disease progression. Clinical triggers allow the brand to concentrate high-value EHR impressions on situations where its information may be relevant to an active treatment decision, rather than delivering messages indiscriminately to a broad physician audience.
But as noted earlier, the specificity that makes this approach valuable can also limit available impressions. When qualifying chart matches are scarce, or triggering capabilities vary across EHR systems, delivering enough impressions to meet campaign objectives becomes more challenging.
So how can brands maintain that clinical precision while achieving sufficient reach to deliver the desired impact?
Understanding the Types of Triggers in EHR Advertising
When evaluating a trigger program, it's helpful to understand two activation mechanisms that may contribute to campaign delivery:
- EHR triggers: A trigger looks for a match in local EMR data, most commonly the patient chart, to activate a brand message
- Claims-based triggers: A trigger that looks at prior claims data for a given HCP, then uses matches in that dataset to target brand message
These approaches use clinical information differently. EHR triggers determine when a message is relevant to the patient chart being reviewed. Claims-based triggers identify physicians whose historical treatment activity matches a brand's clinical criteria, but doesn't establish that a qualifying patient is being seen when the message appears.
When used together, these approaches can preserve a consistent patient definition while expanding reach beyond the EHRs that support chart-based triggering. Understanding that relationship—and how much delivery comes from each method—is critical to evaluating a campaign's precision and scale.
When used together, build on shared criteria, and transparently disclosed, these two types of triggers naturally complement each other: EHR triggers provide responsiveness to current patient context, while claims-based triggers expand reach to additional HCPs who treat the same eligible patient population.
But if criteria are not shared across both triggers, or the split between EHR and claims-based triggers is not disclosed, that harmony breaks down, and can lead to misunderstandings about how data is being used and when messages are being served, while also threatening campaign performance.
Why Transparency in EHR Physician Targeting Matters
To understand how the lack of transparency around triggers can lead to misunderstanding, consider two scenarios:
- In the first, a physician reviews a patient chart that meets a brand's clinical criteria. That chart match triggers a message within the EHR workflow.
- In the second, a physician receives a message because historical claims data identified them as someone who treats relevant patients. The message may be delivered instantly within the EHR, but its appearance wasn't triggered by the patient currently being seen.
Both messages appear in the EHR. Both may reach a relevant physician. But only the first is responsive to the clinical circumstances of that particular patient encounter. This is why terms like "real-time" and "in-workflow" deserve a closer look.
- "Real-time" might refer to how quickly an impression is delivered, how recently targeting data was refreshed, or whether the message responds to current clinical information. These aren't necessarily the same thing.
- Similarly, "in-workflow" can describe a number of places where a brand message might appear, such as the patient chart, e-prescribe module, benefits checks, prior authorization tools, etc., not all of which occur before or during a treatment decision.
Without clear definitions, marketers may assume that all impressions delivered through a triggered program share the same relationship to current clinical context. Marketers should understand what initiates that evaluation, if the message appears at a time when it can influence brand choice, and whether those capabilities are consistent across the EHR network.
Transparency should also extend to performance. When evaluating claims of improved prescription lift or campaign conversion, marketers should have full visibility into how results measured, what comparison groups were used, and whether the outcomes can be attributed to the targeting methodology itself. Greater precision may support stronger results, but understanding how those results were achieved is just as important as the headline number.
Five Questions to Ask Your EHR Advertising Partner
Greater transparency starts with asking a few practical questions:
- What actually triggers my message? Is it a match in the current patient chart, historical treatment data, or a combination of activation methods? If multiple mechanisms are used, can you disclose the exact proportional reach?
- Where (and when) in the workflow do messages appear? Will HCPs see them before or after a treatment choice is made?
- What do you mean by "real-time"? Does it refer to clinical data evaluation, the targeting decision, or the timing of message delivery?
- How do you extend reach without sacrificing precision? Are the same patient eligibility criteria maintained across targeting approaches, or are they broadened to achieve greater impression volume?
- What can I verify through reporting? Can I see HCP-level reach, frequency, activation-method breakdowns, and evidence supporting performance claims?
These questions aren't about favoring one approach or vendor over another. They're about understanding what you're buying and ensuring the methodology supports your brand's objectives.
Precision, Reach, and Transparency Should Go Hand in Hand
Precision and reach don't have to be mutually exclusive. And achieving both shouldn't mean sacrificing transparency or performance.
Clinical triggers offer pharmaceutical marketers a powerful way to make EHR messaging more responsive to patient care. And by combining chart-based triggering with complementary, clinically informed targeting, brands can create more opportunities to reach relevant physicians without abandoning the criteria that define their patient population.
But targeting sophistication alone doesn't guarantee campaign effectiveness. Marketers need to understand where their messages can be triggered, how additional reach is achieved, and what the resulting impressions and outcomes actually represent.
Because ultimately, the value of an EHR advertising strategy shouldn't be judged solely by what its technology promises, but by what it can demonstrably deliver.
