Multiple datasets are the future of marketing strategies

For years, healthcare marketing strategies have been powered by strong but singular datasets: a list of providers to guide outreach, claims data to size a market, affiliation data to understand how a health system is interconnected; the options go on. Each dataset delivered value. Each dataset answered a specific question.

But the healthcare industry doesn’t operate in silos—and neither should your data.

Across life sciences, healthcare IT, the provider space, and beyond, leaders are moving away from siloed datasets and asking a bigger question: how do our disparate datasets work together? Because in a healthcare ecosystem that is defined by consolidation, shifting sites of care, and more informed patients, a single dataset rarely tells the full story. Moreover, marketers are recognizing that isolated insights can create blind spots and cause organizations to miss out on opportunities to succeed.

At Definitive Healthcare, we’ve championed this approach for years, offering multiple, integrated datasets to create a clearer, more comprehensive view of the healthcare landscape. You can hear more about it from Mike Julian, Director of Audience Activation Partnerships at Definitive Healthcare, on the Doceree Dialogue podcast.

When marketers can see organizations, professionals, and patients from multiple angles, the impact can be exponential. We believe this approach to data will be essential to healthcare organizations looking to remain competitive and grow in 2026 and beyond.

Why is this shift happening now?

Several market shifts are expanding both the availability of healthcare data and the need to connect it. Together, they’re accelerating innovation and raising the bar for how organizations use data strategically. Some reasons why this shift toward multiple datasets is happening include:

• AI and ML rely on diverse, high-quality data to be a transformative force in everything from medical imaging and earlier disease detection to predictive analytics. Interconnected datasets give these technologies the fuel they need to operate.
• Wearables like fitness trackers and smart watches are offering physicians access to a range of real-time health data they can integrate with EHRs and other systems to better understand where patients enter the care continuum, detect health concerns earlier, and intervene sooner.
• Data integration and AI are opening new avenues for life sciences organizations when it comes to drug discovery, clinical trial design, precision medicine, and more. This same multi-dimensional view is also influencing commercial strategy, from identifying valuable opportunities to engaging with the right KOLs.
• Telemedicine and remote patient monitoring options are expanding, particularly into rural communities and patients with chronic conditions. Understanding these groups requires connecting data on utilization, organizational investment, provider adoption, demographics, and more.

The challenges involved with multiple datasets

While layering multiple datasets introduces additional complexity, many of the underlying concerns are not new. The same principles that govern responsible use of a single dataset, such as privacy, accuracy, interoperability, and security, still apply. The difference is that when data flows from multiple sources, you must be even more deliberate in how you integrate, manage, and govern it.

• Keeping healthcare data private and secure remains a primary concern among leaders across the industry. A layered data strategy must be built on compliancy-first principles and rigorous governance to protect against leaks and data breaches.
• Physicians can get a comprehensive picture of their patients by gathering data from lab results, EHRs, devices, and more. But if these systems aren’t interoperable, datasets will remain fragmented, and collection won’t be efficient.
• Data collected from multiple sources may sometimes vary in format, completeness, and accuracy, which could distort your analysis. Standardizing your data and ensuring ongoing validation are both essential to maintaining high data quality.
• As the need for healthcare data grows, so does the need for skilled analysts and data scientists who can interpret complex, multilayered information. Not every organization can build that expertise internally, so it’s critical to partner with a trusted data and analytics provider if available.

How multiple datasets create exponential impact

The real value of multiple datasets emerges at the point of intersection. When claims trends inform affiliation structures, when financial relationships illuminate referral pathways, and when consumer insights add behavioral context, insight compounds. Instead of answering one question at a time, organizations gain a multi-dimensional view of the market, and that’s where exponential growth becomes possible.

Here’s what that might look like in practice.

Engaging the right physicians earlier in the patient journey

When it comes to finding the right physicians to champion your device or medication, a single dataset can be incredibly useful. Claims data can help identify which physicians are treating a specific condition, while provider directories can show specialty and geographic distribution.

Timing is everything, however, so if you want to find the right professionals faster and outpace your competitors, you can’t settle for a singular source of data. Doing so keeps your approach to targeting broad rather than precise, making it slower and harder to find and prioritize the most valuable providers that can make a difference in your go-to-market strategy.

Incorporating multiple, layered datasets to your outreach efforts changes that.

For example, by combining de-identified claims data with consumer insights and referral and affiliations data, a more complete view of the patient's journey, and the physicians they interact with, begins to emerge. This new perspective enables your marketing team to ask more nuanced questions such as:

• Which health systems are expanding service lines aligned with my therapy or device?
• Which physicians are seeing an uptick in screening activity?
• Where are referral pathways accelerating and are there areas where leakage occurs?
• Are my affiliated providers consistently sending patients to my specialists?

This layered perspective allows life sciences sales teams, medtech field representatives, and healthcare IT marketers to prioritize physicians based on activity and influence within their slice of the care continuum. The result is more efficient outreach, more relevant conversations, and potentially a stronger resonance between your solution and the HCPs most likely to see your patients.

Prepare for the future of healthcare with multiple datasets

From life sciences to providers to healthcare-adjacent industries, your marketing team needs insights that help them compete in an increasingly more challenging environment. Expanding your perspective on the market with multiple, layered datasets can get you there.

The Atlas Dataset was designed with that goal in mind. The Atlas Dataset links multiple high-quality datasets into one structured, reliable view of healthcare. It’s designed to help organizations plan more effectively, target more precisely, and allocate resources with confidence.

And with flexible data integration options, you can access Definitive Healthcare’s data within the systems and workflows your teams already use.
