The relationship between patients and their healthcare providers has undergone a seismic shift over the last five years, moving away from the traditional, episodic model of care toward a landscape of constant digital connectivity. According to a landmark study published in JAMA in June 2026, the volume of patient-written portal messages surged by 153% between 2020 and 2025.
While the digital transformation of healthcare was accelerated by the COVID-19 pandemic, this latest data suggests that the surge in electronic communication is not merely a lingering byproduct of a public health crisis. Instead, it represents a permanent, structural evolution in how care is delivered and consumed. Yet, as patient engagement reaches an all-time high, the healthcare sector is grappling with an unintended consequence: a mounting administrative burden that threatens to push already exhausted clinicians to the breaking point.
Main Facts: The Rise of the Asynchronous Patient
The JAMA study, which analyzed comprehensive data from Epic electronic health records (EHR) spanning more than 2,000 hospitals and 47,000 clinics, provides a stark visualization of this trend. In 2020, the average patient sent 0.99 messages per year through their health portal. By 2025, that figure had climbed to 2.5 messages per patient per year.
Crucially, this is not a one-way street. Clinicians and support staff have also increased their digital output, with provider-authored messages rising from 4.59 per patient in 2020 to 5.7 by 2025—a 24% increase. The research highlights a clear demographic profile for this trend: messaging is most prevalent among women, patients between the ages of 40 and 64, and individuals residing in neighborhoods with fewer social vulnerabilities—likely reflecting higher levels of digital literacy and access to stable technology.
A Chronology of Digital Transformation
To understand how we arrived at this "always-on" environment, one must look at the timeline of the last half-decade:
- 2020 (The Catalyst): The onset of the COVID-19 pandemic forced a rapid, industry-wide pivot to telehealth. During this period, digital portals became the primary lifeline between patients and clinics, as in-person visits were restricted.
- 2021 (The Peak): The intensity of messaging hit a fever pitch during the height of the pandemic’s surges. Clinician-authored messages more than doubled during this year as providers scrambled to convey testing results, vaccination information, and quarantine guidance.
- 2022–2024 (The New Normal): As the acute phase of the pandemic waned, observers expected communication volumes to return to baseline. Instead, they remained elevated. The "structural shift" occurred here, as patients grew accustomed to the convenience of asynchronous communication for non-urgent health inquiries.
- 2025 (The Consolidation): The JAMA data confirms that the reliance on portals is now entrenched. Despite the return of in-person care, the demand for digital access continues to rise, suggesting that the portal has become a core component of the modern patient experience.
Supporting Data: The Paradox of In-Person Care
Perhaps the most surprising finding of the JAMA research is the refutation of the "substitution hypothesis." Many healthcare economists previously theorized that as digital messaging increased, in-person office visits would decrease, as patients would have their needs met via the portal.
The data suggests the opposite. While telephone visits declined by approximately 6% during the study period, office visits actually rose. This indicates that digital messaging is functioning as a complement to, rather than a replacement for, traditional care. Patients are using portals to clarify instructions, request prescription refills, or seek advice on minor symptoms, but they are still utilizing physical office visits for diagnostic and clinical examinations.
This creates a "double-duty" reality for physicians: they are managing a high volume of digital inquiries while maintaining a full schedule of in-person patient encounters.
Official Perspectives and Clinical Implications
The implications of this shift are profound for the healthcare workforce. Professional medical associations and administrative experts have raised alarms regarding the impact of this "inbox fatigue" on provider well-being.
Dr. Elena Rossi, a primary care physician not involved in the study but familiar with the findings, notes that the "death by a thousand cuts" phenomenon is real. "Every message requires clinical judgment, documentation, and a response. When you have 40 to 50 messages waiting in your inbox after a full day of patients, you aren’t just working an 8-hour shift. You are working until midnight on a laptop," she explains.
The research echoes this sentiment, linking high volumes of EHR tasks to increased rates of burnout, moral injury, and turnover among clinicians. The administrative burden is no longer confined to the clinic walls; it has effectively expanded into the physician’s home and personal life.
The Promise of Artificial Intelligence: A Digital Panacea?
As the healthcare industry confronts the sustainability of this messaging volume, the focus has shifted toward technological interventions—specifically, generative artificial intelligence.
Tech companies and health systems are currently piloting AI tools designed to alleviate the burden of the inbox. These solutions generally fall into three categories:
- Drafting Assistance: Generative AI models are being used to draft responses to common patient queries. The clinician reviews and edits the AI-generated draft, significantly reducing the time spent typing.
- Triage and Prioritization: Advanced algorithms are now capable of scanning incoming messages to categorize them by urgency. This ensures that life-threatening or time-sensitive messages are surfaced to the clinician immediately, while routine questions can be handled by support staff or AI assistants.
- Administrative Automation: AI is being integrated to pull patient data directly from the EHR into the response, ensuring that the clinician doesn’t have to navigate through multiple tabs to find lab results or medication histories while replying.
However, these tools are not without risks. Critics argue that relying on AI to communicate with patients could erode the "human touch" that is vital to the doctor-patient relationship. Furthermore, the potential for AI "hallucinations"—where the software provides medically inaccurate information—remains a top concern for risk management teams.
Conclusion: Balancing Convenience and Sustainability
The rise of patient-provider messaging is a testament to the success of digital health integration. It has improved patient satisfaction, empowered individuals to take control of their medication adherence, and provided a seamless channel for preventative care. These are objectively positive outcomes for the population’s health.
Yet, the JAMA study serves as a critical warning. The current trajectory is unsustainable if it continues to come at the expense of clinician mental health and operational efficiency. The next phase of healthcare evolution will likely not be defined by how much we can communicate, but by how we can refine that communication to be more efficient, more automated, and ultimately, more human.
As hospitals and health systems look toward the latter half of the decade, the challenge will be to preserve the benefits of digital access while creating structural guardrails that protect the workforce. Without a balanced approach—one that combines technology with clear communication policies—the digital portal, once a beacon of modern care, risks becoming a bottleneck that inhibits the very system it was designed to improve.
