Clinician In The Lead (CITL): Why Healthcare Must Be Clinically-Led by Design

The rise of artificial intelligence and digital health tools has prompted a fundamental rethink of how healthcare is designed and delivered. From chatbots performing initial triage to machine learning algorithms flagging radiological anomalies, technology is becoming an indispensable layer within modern health systems. Amid this transformation, one mantra has gained traction: keep a "human in the loop."

But who, precisely, is that human?

In sectors like finance or manufacturing, the term "human in the loop" (HITL) may be sufficient. A technical person with contextual awareness and good judgment might effectively monitor or override a system. In healthcare, however, the term feels overly broad, and at times, dangerously vague. When clinical decisions hang in the balance, the mere presence of a human is not enough. It must be the right human. And that means a clinician.

Enter: Clinician in the Loop (CITL).

Yet even this concept does not go far enough. If we are serious about building safe, effective, and equitable health systems, we must move beyond simply involving clinicians in decision-making loops. We must place them in positions of leadership. In other words, it is time to reframe CITL as Clinician in the Lead.

From Reviewer to Architect

Too often, clinicians are asked to review digital tools after they have already been built. Perhaps a physician sits on an advisory board. Maybe a nurse is asked to provide feedback on a prototype. These are important steps, but they fall short of true co-creation. A loop that invites a clinician in only after the decisions are made is not a loop at all. It is a cul-de-sac.

Contrast this with what we see at places like Mayo Clinic, where clinicians are embedded directly into AI development teams. Here, the role of the clinician is not just to validate whether a model's output is clinically plausible. Instead, they help frame the problem, define success metrics, and stress-test assumptions in real-world scenarios. The result? Algorithms that are not only intelligent, but also relevant, safe, and trusted.

At NHS Digital, clinicians serve as Clinical Safety Officers. Their role is to ensure that any digital tool deployed across the NHS estate adheres to a robust standard of clinical safety and risk management. This is not a ceremonial title. These officers have formal authority to question, halt, or revise implementations if clinical risk thresholds are exceeded. It is a model of what governance looks like when clinicians are not only in the loop, but structurally empowered.

The Portfolio Physician: A Bridge Between Worlds

This evolution in role demands a new breed of clinician. Not just the bedside physician, but the portfolio physician: someone who spans clinical, digital, operational, and even policy domains. These individuals are uniquely positioned to bridge the often-siloed worlds of healthcare and technology.

The concept is not new. Throughout history, we have seen figures who embodied this multidimensional ethos. During the Islamic Golden Age, polymaths like Ibn Sina (Avicenna) and Al-Razi (Rhazes) exemplified what we would today recognize as portfolio physicians. Ibn Sina was not only a practicing physician but also a philosopher, astronomer, and mathematician. His seminal work, The Canon of Medicine, remained a central text in both the Islamic world and Europe for centuries, and it reflected his ability to integrate medical science with broader epistemological and ethical frameworks. Al-Razi, similarly, was known for his clinical practice, his work in chemistry (which laid the foundations for modern pharmacology), and his writings on medical ethics and public health.

These historical figures moved fluidly between theory and application, scholarship and service. They were deeply embedded in the social and institutional systems of their time, often advising rulers, educating students, and contributing to infrastructure such as hospitals. Their enduring impact speaks not just to their intellect, but to their integrative approach to knowledge and action.

Today, a portfolio physician might spend part of their week in clinic, another part in product development meetings, and yet another reviewing regulatory frameworks or engaging in academic research. Their superpower is not just clinical insight, but the ability to apply that insight across diverse settings. When positioned correctly, they become the connective tissue of modern health innovation.

These clinicians also play a key role in ensuring that innovations remain focused on patient benefit, rather than technological novelty. Their presence can act as a real-time feedback loop that questions whether a new tool is solving the right problem, or merely creating a new layer of digital noise.

Beyond Design: Leadership in Implementation and Evaluation

Putting clinicians in the lead is not just about shaping new tools. It is also about how we implement and evaluate them. Too many digital health pilots flounder because they are deployed without meaningful input from the clinical workforce. A dashboard might offer predictive analytics, but if it does not integrate with the clinical workflow, or if it generates alerts clinicians do not trust, it quickly becomes shelfware.

In Cleveland Clinic, digital initiatives are not rolled out without clinical co-leadership. Projects are jointly overseen by clinician informaticians and operational leads, with success defined not by engagement metrics alone, but by clinical outcomes and workflow alignment. This collaborative approach ensures both adoption and impact.

Even in remote patient monitoring, where algorithms flag out-of-range vitals, the most successful programs include clinicians in the evaluation of data thresholds, alert fatigue, and patient engagement. When clinicians are in the lead, they do not just ensure clinical safety. They act as stewards of value.

Collaboration: It Takes an Ecosystem

None of this means that clinicians should go it alone. Healthcare innovation is inherently interdisciplinary. Data scientists, engineers, administrators, ethicists, and designers all have essential roles to play. The goal is not clinician exceptionalism, but clinician integration.

What we need is a new model of distributed leadership, where clinicians are partners from ideation to evaluation. In this model, clinicians bring the domain knowledge, while others bring the tools and systems expertise to operationalize that knowledge.

This is already happening in settings like Stanford's Partnership for AI-Assisted Care, where physicians, computer scientists, and ethicists co-develop tools in a shared governance model. The same ethos is visible in WHO's guidance on digital health ethics, which calls for multi-stakeholder co-creation with clinicians in central roles.

Minimal Loops, Maximum Impact

There is a time and place for bullet points, so here are a few closing reflections on what Clinician in the Lead really looks like:

• It means clinicians are not consulted after the fact, but shape the digital strategy from the outset.

• It requires new training pathways, including digital fellowships and leadership tracks for clinicians.

• It depends on health systems building new roles, incentives, and protections for clinicians who take on these responsibilities.

• And most of all, it demands humility from every stakeholder, recognizing that good healthcare is not just about what works technically, but what works clinically and ethically.
