Harvard: Top 6 Health System Investments 2024

Investing in Primary Care: A Roadmap for Health Systems

A new guide from Harvard Medical School identifies six key investments to transform primary care and improve health outcomes.

• The U.S. spends only 4.6% of its healthcare dollar on primary care, despite 98 million Americans living in shortage areas.
• Harvard Medical School’s new Primary Care Investment Guide offers an evidence-based plan for allocating capital to team-based care.
• Six “Advanced Primary Care” (APC) services—including behavioral health integration and e-consults—show measurable returns on investment.
• The report highlights a “technological and financial firewall” hindering the scale of these improvements.
• Five states have already legislated increased primary care spending, signaling a shift away from fee-for-service medicine.

The American healthcare system faces a glaring paradox: we spend more than any other nation, yet consistently underfund the very foundation of good health – primary care. A shockingly small 4.6 cents of every healthcare dollar goes to primary care, a chronic underinvestment that has created a workforce crisis leaving nearly 98 million Americans without adequate access. But a new roadmap for change has arrived.

The Harvard Medical School Center for Primary Care, in collaboration with the Primary Care Collaborative, recently released the Primary Care Investment Guide (PCIG). This isn’t just another policy paper gathering dust on a shelf; it’s a practical manual designed to direct capital where it will actually improve health. “Investing in advanced primary care works and is required to strengthen primary care so we can improve the nation’s health,” said Amie A. Pollack, Director of Research at the Harvard Center for Primary Care. “When more investment supports the frontline team… clinicians experience less burnout and more joy in practice.”

Top 6 Investments for Health Systems

At the heart of the report lies a detailed analysis of six “Advanced Primary Care” (APC) services. These aren’t abstract ideas; they are concrete, investable workflows that can transform a traditional clinic into a proactive health hub.

1. Behavioral Health Integration (BHI) The report identifies BHI as a crucial step in reducing emergency department (ED) visits. By integrating psychologists or care managers directly into primary care—using models like Collaborative Care (CoCM) or Primary Care Behavioral Health (PCBH)—practices can address the “whole person” more effectively.

The Tech Angle: To address psychiatrist shortages, leading systems are utilizing tele-behavioral health and AI-enabled therapy tools to expand capacity. ROI: Studies have shown returns as high as 6199% in specific safety-net settings by reducing downstream healthcare utilization.

2. Integrated Clinical Pharmacy This goes beyond simply filling prescriptions. The guide recommends embedding pharmacists to expertly manage complex chronic conditions like diabetes and hypertension.

Impact: 12 out of 14 studies reviewed demonstrated positive financial returns, with significant reductions in hospitalizations when pharmacists managed medication adjustments and prior authorizations.

3. Data-Driven Population Health Shifting from focusing on individual “patient care” to managing the health of an entire “panel” requires a robust data infrastructure. Successful models employ centralized analytics teams to identify high-risk patients and deploy remote monitoring tools.

The Finding: 73% of diabetes population health interventions analyzed reported cost savings.

4. Social Determinants of Health (SDOH) The guide emphasizes that medical care is only one piece of the health puzzle. Effective APC models utilize Community Health Workers (CHWs) and screening tools to connect patients with essential resources like housing and food assistance.

Innovation: Hybrid models combining internal navigators with external community-based organizations (CBOs) are proving most effective at resolving non-clinical barriers to care.

5. E-Consults Technology enabling primary care physicians (PCPs) to connect with specialists asynchronously is a game-changer for access to care.

Efficiency: E-consults streamline decision-making and reduce unnecessary referrals, keeping care within the more affordable primary care setting. Financials: All eight studies reviewed on e-consults demonstrated cost savings, primarily by avoiding in-person specialist visits.

6. Care Management Proactive care management is essential for patients at highest risk. The report highlights that the return on investment is greatest when focusing on individuals at immediate risk of hospitalization.

The Interoperability and Payment Gap

While the clinical benefits are clear, the report reveals a significant “technological and financial firewall” hindering widespread adoption.

The “Black Box” of Funding Payers interviewed for the report expressed frustration with the lack of transparency in how increased primary care payments are actually used. Funds are often absorbed by health system administrative costs, rather than reaching the frontline clinicians.

Recommendation: The guide calls for enforceable mechanisms to ensure “dollars reach the full primary care team,” coupled with transparent tracking of primary care spending.

The Tech Burden For APC to function effectively, data must flow seamlessly. The report notes that interoperability remains a major obstacle, with clinicians struggling to access timely data across fragmented systems.

The Fix: Payers and providers must establish “near real-time data-sharing partnerships” to support population health and outreach.

Why This Matters Now

The timing of this guide is particularly important. Five states—California, Colorado, Delaware, Oregon, and Rhode Island—have already enacted legislation mandating increased primary care spending. As 2026 approaches, the market is signaling a clear shift away from the outdated fee-for-service model. The organizations that leverage this guide to build the necessary infrastructure—both human and digital—will be best positioned for success in the evolving value-based healthcare landscape.

“Every decision-maker who wants to shift our health care system to health and away from more expensive services will benefit from this guide,” said Ann Greiner, President and CEO of the Primary Care Collaborative.
