Why Your CDP Might Need a Checkup (And a Little Data Therapy)

The Difference Data Quality Makes in Activating Healthcare Audiences

In healthcare, data is serious business—people’s lives and privacy depend on it. But when it comes to Customer Data Platforms (CDPs), we sometimes forget a simple truth: even the most sophisticated platform is only as good as the data it ingests.

You wouldn’t build a hospital on a swamp, so why build patient engagement strategies on messy, mismatched, mystery data?

Let’s talk about how the right data—clean, normalized, behaviorally rich, household-aware, and intentionally structured—can transform your CDP from a high-maintenance headache into a healthy engine for activation. With just a little TLC (Tender Loving Configuration), your CDP can do what it was built to do: connect, engage, and help your patients and members feel truly known.

The Patient Is In: Your CDP and the Quality of the Data

Let’s get one thing straight: CDPs don’t magically unify data—and they definitely don’t all do it the same way.

Some rely heavily on deterministic matching. Others lean into probabilistic models or proprietary identity graphs. Some give you full control over the matching logic. Others… well, let’s just say they’re more “black box with a user manual that gaslights you.”

That’s why choosing the right CDP for your vertical is just as critical as preparing the right data. A platform built for retail won’t solve for healthcare’s complex data relationships, regulatory constraints, or household dynamics.

Think of your CDP like a nutritionist. If it’s only trained to read food labels—not medication charts—it’s going to be overwhelmed by the chaos of multi-source, multi-format healthcare data. And if all it gets is sugar-laden, duplicate-filled spreadsheets and partial MRNs from four overlapping systems, it’s going to need therapy. Or worse—your marketing team might.

In healthcare, data silos are basically family heirlooms: ancient, mysterious, and a little bit cursed. Lab systems, EMRs, CRMs, DMPs, patient portals, marketing clouds—each tells a slightly different story about the same person. The CDP’s job is to bring these puzzle pieces together intelligently. That means your success depends not just on what you feed it, but how it’s wired to digest it.

Normalize Like Your Engagement Depends on It (Because It Does)

Before you start running audience queries or building real-time triggers, take a deep breath—and normalize your data. Seriously.

Name fields: One person, many spellings. One system’s “Jon” is another’s “Johnathan A. (Jr)”—and yet another’s “J. A. Smith Jr.” To unify those into a single profile, you need more than luck. Algorithms like Levenshtein distance, Jaro-Winkler, or phonetic matching (Soundex, Metaphone) help detect near-duplicates. But rules-based logic—like stripping suffixes, standardizing nicknames, or expanding initials—is key to achieving true consistency.
Email: LOWERCASE EVERYTHING. And for the love of deduplication, pick one field and stick with it. Or at least make sure your clustering and matching logic isn’t case-sensitive behind your back. Know the rules of IDR before chasing your tail.
Dates: Decide on a format—MM/DD/YYYY or bust. Your CDP is not a mind reader.
IDs: Choose your master ID wisely and treat it like the North Star—especially when multiple data sources are involved (and they always are). Ideally, don’t let your CDP issue new IDs for the same person in every feed.

Think of normalization as a spa day for your CDP—it helps everything run smoother, look better, and avoid unnecessary flare-ups. Just remember: normalization should happen as data is ingested, not at the source. Otherwise, you risk changing the original data and putting yourself in a compliance pickle.

Beyond the Individual: Life-Stage Outreach for the Modern Household

Patients don’t live in silos—and neither should your data. Take Maria’s household, for example:

Maria, 30, just welcomed her first baby. She lives with her husband Thomas, 59, his two teens from a previous marriage, and Thomas’s 82-year-old mother, who is nearing memory care needs.

Five people. Five different life stages. One inbox: Maria’s.

Your CDP needs to recognize this household as a single, interconnected care unit while delivering personalized outreach for each person’s journey. That means:

Identifying Maria as the primary contact
Tracking care journeys individually, but through a household lens
Using location context (like Thomas’s work address) to recommend more convenient clinics
Delivering targeted content, like:
- “Your baby is due for their next wellness visit”
- “Here’s what to expect during postpartum recovery”
- “A clinic near Thomas’s work has availability this Thursday”
- “Memory care support for your mother—how to get started”

When your CDP understands households and life stages, you reduce logistical barriers, boost relevance, and build trust by showing you get it. Because modern healthcare isn’t one-size-fits-all—it’s family-sized.
