A ton of organizations are using (our) reference and affiliation data to sell into healthcare—here's why

Selling into the healthcare space is difficult—especially if healthcare isn’t your primary or secondary market. Want to succeed in the space? You need to de-tangle, understand, and leverage the connections that define it: ownership structures, referral patterns, claims transactions leakage patterns, and too many more to list. Definitive Healthcare is your best bet for making sense of it all—and that’s not just speculation.

Definitive Healthcare ranked #1 for healthcare reference and affiliation data

Don’t take my word for it: We partnered with a leading independent research firm to survey leaders and professionals from a diverse array of organizations across the market about their usage of healthcare reference and affiliation data. The results were clear: Whether you’re in facility services, software and IT, or construction (or just about anyone else who does business in healthcare), Definitive Healthcare is the preferred choice for the data you need.

Speaking of the data you need, we ranked #1 in eight of the top data categories:

We also ranked #1 for the top 10 use cases for healthcare reference and affiliation data—the core of our intelligence that so many organizations prefer. But that’s not all we learned:

  • Most users are leveraging data to target key decision-makers, optimize sales intelligence, and identify decision-makers and influencers.
  • Executive contact information, provider names, and other contact information topmost organizations’ data wish lists.
  • Just over half of these organizations feel strongly that their teams have the data and insights they need to identify the right prospects.

Of course, those are just the highlights. You can read the full report here.

What is reference and affiliation data, anyway?

Healthcare reference data is the firmographic, location, and financial data for hospitals and other healthcare facilities. It also includes the demographic, contact, and location information for healthcare providers.

Affiliation data explains how healthcare organizations and providers are connected to one another, helping you understand the relationships between providers, facilities, physician groups, integrated delivery networks, accountable care organizations, government organizations, and other healthcare networks and systems.

You can use both types of data together to create useful intelligence about the market and find answers to questions like who works where, which facilities are affiliated with each other, and how billing is handled within a network.

Unsurprisingly, a wide variety of organizations are already incorporating this data in their planning and daily operations. As the research shows, they’re choosing to get it from Definitive Healthcare more often than not, because we make deriving insights from the data simpler, more accessible, and ultimately more useful across organizations.

So why Definitive Healthcare?

Look, we don’t want to toot our own horn too much—but we absolutely will when we have the data to back it up.

Our survey respondents ranked Definitive Healthcare as the #1 vendor for the top 10 use cases for reference and affiliation data, as well as for data across eight categories including hospital contacts, health system intelligence, and quality, clinical, and financial metrics. This puts us ahead of industry heavyweights like ZoomInfo, LexisNexis, and IQVIA.

So what do we do differently? Just look at the qualities that respondents rated as “very important” for their reference and affiliation data purchasing decisions:

Accuracy, completeness, timeliness, and ease of access were their most critical factors for evaluating vendors. Plus, these organizations preferred to pick and choose their own data fields and opted for custom solutions over out-of-the-box products.

Definitive Healthcare delivers on all those categories while also providing access methods that most closely align with these companies’ reported preferences: portal access with routinely updated data, as well as integration options with analytics solutions.

A full 39% of respondents said their teams spend a lot of time matching data across datasets, but let’s face it—that’s not the focus or central skillset of your sales and marketing teams. Our Atlas Reference & Affiliation Dataset removes the need for that effort entirely.

In other words, companies across the healthcare landscape say they’re getting the high-quality data they need, in the formats and systems they prefer, from Definitive Healthcare.

Reference and affiliations data goes beyond sales and marketing

But you don’t need to be an industry leader to leverage this data—you just need to want to sell into healthcare.
