Healthcare is one of the largest and most lucrative B2B markets in the United States. Medical devices, pharmaceuticals, health information technology, practice management software, staffing services, and a vast ecosystem of supporting products and services flow through a system that accounts for nearly a fifth of U.S. GDP. The opportunity for vendors who figure out how to navigate this market is enormous.
But healthcare B2B marketing in 2026 looks fundamentally different from what it looked like ten years ago. The independent physician practice, which was the core unit of the healthcare market for decades, has been absorbed into hospitals, health systems, and private equity-backed management organizations at a pace that has transformed the contact data landscape, the decision-making structure, and the purchasing dynamics across nearly every product category.
This guide covers everything a healthcare B2B vendor needs to understand to compete effectively in this consolidated environment: how the market has restructured, who holds purchasing authority now, how to build a two-layer contact strategy that covers both clinical and administrative decision-makers, what quality physician and healthcare contact data looks like, and the specific campaign approaches that generate results in 2026.
Part One: The Consolidated Healthcare Market
The Scale of Physician Consolidation
The consolidation of American physician practices into large institutional structures has been one of the defining trends in healthcare over the past decade, and it has accelerated significantly since 2020. The American Medical Association tracks physician practice ownership annually, and the trend line is unmistakable: the share of physicians working in physician-owned practices has declined from a majority to a minority over roughly a decade.
Hospital and health system employment of physicians has grown correspondingly. In many major metropolitan markets, the large regional health systems directly employ a significant majority of the physicians in that market. In some specialties, the independent practitioner has effectively become a rarity.
Private equity has added another layer of complexity. PE-backed physician management organizations and management services organizations have consolidated entire specialties in major markets. Dermatology, gastroenterology, ophthalmology, orthopedics, and primary care have all seen significant PE consolidation. In some metro areas, a single PE-backed group controls a large share of the practices in a given specialty.
What This Means for Vendors
For vendors who built their healthcare marketing approach around reaching independent practitioners, consolidation has created a compounding problem. The physician contacts that represented purchasing authority in those practices no longer have that authority for many categories of purchase. The email addresses tied to those physicians have in many cases migrated to institutional domains. And the decision-makers who now control the relevant budgets are in an administrative layer that legacy physician databases often do not cover.
The result is a healthcare marketing environment where sending campaigns to a legacy physician list produces declining results not because the product is wrong or the message is wrong, but because the contact data points to a purchasing authority structure that no longer exists.
Understanding this structural shift is the prerequisite for rebuilding an effective healthcare marketing approach.
The Private Equity Dynamics
Private equity healthcare consolidation has created a specific contact data challenge that deserves direct attention. When a PE-backed management services organization acquires a portfolio of independent practices, it creates a new administrative layer, the MSO, that sits above the clinical practices and controls procurement for most non-clinical categories.
The executives at the MSO level are not physicians. They are professional managers: a CEO of the management services organization, a VP of Operations, a Director of Supply Chain or Procurement, and in some cases operating partners from the PE firm itself who are focused on margin optimization. These are the purchasing decision-makers for the product and service categories that used to be decided by individual physicians.
These contacts do not appear in legacy physician databases because they are new roles created by the consolidation wave itself. Reaching them requires data sourcing that specifically tracks MSO formation and growth, not just traditional physician directory sources. Physician Data tracks this layer and maintains verified contacts for MSO-level decision-makers alongside the clinical physician contacts.
Part Two: The Two-Layer Contact Strategy
Why You Need Both Layers
The most common strategic mistake in consolidated healthcare marketing is choosing between clinical contacts and administrative contacts rather than maintaining both. The reality is that effective healthcare B2B marketing in 2026 requires both layers working together.
Clinical contacts matter because physician preference is still a significant factor in many purchasing decisions, even in fully consolidated environments. A physician who advocates for a specific product within their health system creates pull that procurement teams respond to. In medical device categories, clinical preference is often the primary driver of purchase decisions, with the administrative layer essentially ratifying what the clinical team has selected. In pharmaceutical categories, formulary decisions involve clinical pharmacists and medical directors alongside procurement staff.
Administrative contacts matter because physician preference without an administrative champion produces stalled deals. The physician who wants your product cannot always purchase it unilaterally. The contact who can approve the purchase is often someone the physician has never met: a VP of Supply Chain, a Director of Procurement at the health system level, or a financial officer at the MSO.
Campaigns that reach only the clinical layer create awareness and preference that cannot convert without an administrative path to purchase. Campaigns that reach only the administrative layer lack the clinical validation that most health system administrators require before approving a purchase. The winning approach is coordinated outreach to both layers at the same institution.
Building the Clinical Layer
The clinical contact layer covers physicians and other clinicians by specialty, practice setting, and geography. For most healthcare vendors, this layer should be filtered to the specific specialty or specialties most relevant to the product, to the practice settings where the product applies, and to the geographic markets where the vendor has implementation capability.
Clinical outreach messaging should be evidence-forward and clinically credible. Physicians respond to peer-reviewed research, clinical outcome data, references from recognized colleagues, and clear descriptions of how the product fits into their specific clinical workflow. They are skeptical of claims that are not backed by evidence and are quick to dismiss messaging that feels like it was written by a marketer who does not understand clinical practice.
Clinical email campaigns should use subject lines and opening lines that reference the specific specialty and clinical context. ‘For Gastroenterologists: New Evidence on Adenoma Detection Rates’ will outperform ‘Improve Your Clinical Outcomes’ by a wide margin.
Building the Administrative Layer
The administrative contact layer covers the procurement, operations, and leadership contacts at health systems, hospital networks, and PE-backed management organizations. This layer requires different contact sourcing than the clinical layer and a fundamentally different messaging approach.
Administrative contacts respond to ROI framing, implementation simplicity, integration with existing infrastructure, and vendor track record at comparable institutions. They are not making clinical judgments. They are making business decisions: is this the right product at the right price from the right vendor, and can we implement it without disrupting clinical operations?
Administrative outreach messaging should lead with financial and operational outcomes. Cost reduction, workflow efficiency, compliance risk mitigation, and integration with existing technology infrastructure are the themes that resonate at the administrative layer. Clinical efficacy matters as background context, but it is rarely the primary driver of an administrative purchasing decision.

Part Three: Contact Data Quality in Healthcare
How Healthcare Contact Data Decays
Healthcare contact data decays through several mechanisms that legacy databases are not designed to track.
The most straightforward mechanism is employment change. Physicians who move from independent practice to employed settings change their email addresses, their titles, and often their clinical focus. Health system administrators who change roles or institutions create similar decay. The turnover rates in healthcare administration, particularly at the VP level, rival those in education.
The consolidation mechanism is more complex. When a PE-backed group acquires a practice, the individual physician records may remain technically accurate at the name and email level while becoming inaccurate at the purchasing authority level. The physician is still there. Their email still works. But they no longer make purchasing decisions in the categories that used to be their domain. Legacy databases do not capture this context shift.
The MSO formation mechanism is the newest and least-addressed source of inaccuracy. Management services organizations that did not exist three years ago are now the purchasing authorities for entire specialty networks in major markets. If your database does not have MSO-level contacts, it is missing decision-makers that did not exist when the database was last compiled.
What Quality Healthcare Contact Data Looks Like
Quality healthcare contact data must address all three decay mechanisms. That means not just maintaining physician contact records but also tracking employment status changes that affect purchasing authority, building and maintaining MSO-level administrative contacts, and regularly updating health system organizational charts to reflect the current structure of the institutions where decisions are actually being made.
Physician Data maintains records at multiple layers of the healthcare market: clinical physician contacts by specialty and practice setting, health system leadership and administrative contacts by role and system size, and MSO-level management contacts for PE-backed physician groups. The database is verified continuously, with records updated when employment changes, organizational restructurings, or MSO formation events are detected.
Part Four: Frequently Asked Questions
What percentage of U.S. physicians now work for a hospital or health system?
According to the American Medical Association and multiple healthcare policy research organizations, the majority of U.S. physicians now work for a hospital, health system, or corporate entity rather than an independent practice. The share of physicians in physician-owned practices has declined from roughly 60 percent in 2012 to below 50 percent by 2020, with continued decline since. The specific numbers vary by specialty and geography, with higher rates of consolidation in metropolitan areas and in specialties that have been most actively targeted by health systems and private equity.
Who makes purchasing decisions in a consolidated health system?
In a consolidated health system, purchasing authority for most product and service categories has migrated from individual physicians to administrative decision-makers. VP-level executives in Supply Chain, Information Technology, and Operations typically control procurement for technology, devices, and services. Clinical decisions still involve physicians, particularly for medical devices and pharmaceutical preferences, but final purchasing authority usually sits in the administrative layer.
What is a management services organization (MSO) in healthcare?
A management services organization, or MSO, is a corporate entity that provides management, administrative, and business support services to physician practices under its umbrella. In the context of PE-backed healthcare consolidation, an MSO typically sits above a portfolio of acquired practices and handles contracting, procurement, human resources, and financial management for all practices in the network. The MSO executives are the relevant purchasing decision-makers for most non-clinical product and service categories.
How should healthcare vendors adjust their outreach for a consolidated market?
Healthcare vendors should adopt a two-layer contact strategy that reaches both clinical contacts for preference-setting and administrative contacts for purchasing conversations. Clinical outreach should be specialty-specific and evidence-forward. Administrative outreach should lead with ROI and operational outcomes. At the same institution, coordinated outreach to both layers produces better results than targeting either layer alone.
How often should healthcare contact data be refreshed?
Healthcare contact data should be refreshed at least quarterly given the rate of consolidation activity, employment changes, and organizational restructuring in the current market. For specialties with high PE consolidation activity, monthly verification is more appropriate. Any database that has not been updated in the past 12 months should be treated as potentially significantly inaccurate, particularly for contacts at MSO-level and health system administrative roles.
What specialties have seen the most physician consolidation?
The specialties with the highest rates of PE-backed and health system consolidation include dermatology, gastroenterology, ophthalmology, orthopedics, and primary care. Emergency medicine has been significantly consolidated through national staffing groups. Radiology and pathology have long operated primarily within hospital system structures. Surgical specialties and hospital-based specialties generally have higher consolidation rates than office-based specialties, though the gap has narrowed significantly.
Conclusion
Healthcare B2B marketing in 2026 requires a fundamental update to the strategies and contact data that most vendors built around the independent practice model. The consolidation wave is not reversing. The administrative layer that now controls purchasing authority is not going to give that authority back to individual physicians. And the private equity dynamics that have reshaped entire specialties are accelerating rather than slowing.
The vendors who win in this environment are the ones who build their outreach around the actual structure of the consolidated healthcare market: verified contacts at both the clinical and administrative layers, messaging calibrated to each layer’s decision-making priorities, and data that tracks the MSO-level organizations that did not exist a few years ago.
