The Warm Handoff in Diabetes Care: More Than a Metabolic Problem

This post is part of an ongoing series on the Primary Care Behavioral Health (PCBH) model. If you are new to the blog, I would encourage you to start with my earlier posts on what primary care is, the models of behavioral health integration, the GATHER framework, and the warm handoff series.

In Fresh Fruit, Broken Bodies: Migrant Farmworkers in the United States, Seth Holmes follows a group of Triqui farmworkers from the mountains of Oaxaca to the strawberry fields of Washington State, documenting what happens to their bodies under conditions of structural violence . The book is many things—an indictment, an elegy, a work of embodied anthropology—but its central argument is deceptively simple: the body does not suffer in a vacuum. Illness is always also a social event, shaped by the forces a person navigates before they ever arrive at a clinic. Holmes shows that the bent backs and destroyed knees of farmworkers are not incidental misfortunes but the predictable consequence of a labor system that treats human beings as instruments of production. Medicine’s tendency to locate pathology inside the individual body, he argues, obscures the structural origins of that pathology and forecloses the kinds of interventions that might actually help.

I think about Holmes regularly when I work with patients who have diabetes.

Diabetes is one of the conditions that primary care teams most readily imagine as “purely medical”—a matter of glucose, insulin, hemoglobin A1c, and the careful management of diet and medication. The behavioral health consultant’s role in diabetes care is therefore sometimes imagined as supporting, supplementary, or contingent: a resource available if the patient happens to be depressed, or resistant to self-management, or struggling with something overtly psychological. From this view, the primary care provider (PCP) owns the diabetes, and the behavioral health consultant (BHC) is called in to handle the complications.

This post argues for a different view. Diabetes is not a metabolic problem that happens to have psychological complications. It is a biopsychosocial condition from the moment of diagnosis, and the warm handoff is not a response to complications but a standard feature of good diabetes care. The BHC’s role in diabetes begins at the same moment as the PCP’s—not as a specialist managing the edges but as a member of a team that sees the whole person.

The Psychological Landscape of Diabetes

The case for behavioral health involvement in diabetes care begins with epidemiology. The co-occurrence of psychological distress and diabetes is not an occasional finding; it is a consistent feature of the population. Lifetime prevalence of depression in adults with diabetes is approximately 25%—roughly double that of the general adult population—and anxiety diagnoses are reported by approximately 20% of adults with diabetes, compared to 17.5% of adults without . These numbers alone would justify routine BHC involvement in diabetes care.

But the more clinically distinctive concept is diabetes distress—the emotional burden specific to living with and managing a chronic illness that demands relentless daily self-regulation. Diabetes distress is distinct from major depressive disorder; it arises not from a mood disorder but from the ongoing cognitive and emotional demands of the disease itself: the fatigue of monitoring glucose levels, the guilt and shame around dietary choices, the worry about long-term complications, the effort of managing medications across every domain of daily life. National survey data from 2021 estimate the prevalence of moderate to severe diabetes distress in U.S. adults with diabetes at approximately 31%, with higher rates among younger adults and those with lower incomes. Diabetes distress is associated with reduced glycemic control, diminished medication adherence, and decreased frequency of self-monitoring .

The problem of stigma compounds all of this. Himmelstein and Puhl found that more than half of adults with type 2 diabetes reported prior experiences of weight stigma, and 40 to 60% reported experiencing weight stigma specifically in healthcare settings. Diabetes-related stigma—the perception that one is personally responsible for one’s illness, or that the illness reflects moral failure around diet and exercise—was also common, with many participants internalizing both forms. The clinical implications are significant. A patient who enters a primary care visit already carrying shame about their condition is unlikely to disclose the full extent of their struggles with self-management, and a provider who interprets poor glycemic control as a problem of willpower or compliance is unlikely to ask the right questions. The warm handoff, framed correctly, interrupts that dynamic by introducing the BHC as a standard part of care rather than as a consequence of failure.

Why the BHC Belongs at the Moment of Diagnosis

The case for the warm handoff in diabetes care is particularly (but not exclusively!) compelling at a specific moment: the day a patient receives a new diagnosis.

A new diagnosis of diabetes arrives with considerable psychological weight. The patient has just been told that their body has changed in a way that will require sustained behavioral adjustment for the rest of their life. They are likely to be confronting a flood of information—about diet, exercise, medications, monitoring, and long-term risks—delivered in the span of a visit during which they are also processing the emotional reality of what they have been told. The American Diabetes Association‘s Standards of Care have explicitly called for psychosocial care to be integrated into all diabetes management, specifically noting that emotional wellbeing is an important component of diabetes care and self-management .

This is precisely the window the warm handoff is built to catch. As I have written in earlier posts in this series, the warm handoff does not merely reduce logistical distance between identification and care—it catches a patient at the specific moment when their readiness to engage is highest, which is also the moment primary care is specifically designed to reach: the 4 Cs framework describes this as First Contact, the function of being the point at which a patient enters the healthcare system with a new concern . A patient who receives a new diabetes diagnosis and walks out of the clinic without having met the BHC may find that the emotional intensity of that news fades into avoidance. The referral slip—if one was offered at all—becomes another piece of paper in a pile. The patient who meets the BHC on the same day begins the work of integrating behavioral health support into their understanding of the illness before that window closes.

Robinson and Reiter describe exactly this use case when discussing PCBH pathways for patients with chronic conditions, suggesting as a potential outcome target that every patient diagnosed with diabetes receive a BHC or behavioral health assistant visit on the day of the initial diagnosis. A pathway built around the new-diagnosis warm handoff removes the dependency on the PCP noticing that a patient seems emotionally distressed mid-visit; it builds the connection into the structure of care as a matter of routine (GATHER: Routine; 4 Cs: First Contact—BHC involvement is embedded at the moment of diagnosis rather than triggered by visible distress .).

What the BHC Does in the Room

The warm handoff in diabetes care follows the same structural logic as any other warm handoff: identification, offer, and connection, with the BHC completing the visit and communicating back to the PCP the same day . What changes is the clinical content of the visit itself.

The BHC’s first task in a diabetes warm handoff is not to deliver psychoeducation about the disease or to reinforce the PCP’s dietary recommendations. It is to find out who the patient is and what diabetes means to them right now. This is a distinction worth making explicit, because it is easy to collapse the behavioral health role in chronic disease management into health education, and health education—however valuable—is not the same thing. The BHC is not there to repeat the information the PCP has already provided. The BHC is there to understand how the patient is receiving that information, what feelings it is generating, and what functional obstacles stand between the patient and the self-management behaviors that will support their health.

For many patients, the most important initial intervention is simply normalization. Diabetes distress is common and expected; it is not a sign of psychological weakness or diagnostic significance. Naming it as a normal response to an abnormal demand on a person’s life can itself be therapeutic, and it sets the tone for a relationship in which the BHC is a thinking partner rather than another provider with instructions.

The assessment also needs to surface something that goes largely unexamined in the typical medical encounter: the patient’s illness schema. When I get to the presenting concern in a diabetes visit, one question I have returned to throughout my career is this: Do you know anyone with diabetes who is healthy?

The answer is almost always no—or at best a hesitant, qualified yes followed by a story about someone who lost a limb anyway. This is not a failure of patient knowledge. It is an accurate reflection of what most patients have actually witnessed. Diabetes runs in families, and what those families have often witnessed is diabetes at its worst: neuropathy, amputations, renal failure, blindness, early death. The patient sitting across from me has frequently spent years watching what this disease did to a parent or grandparent, and they have filed away that trajectory as the inevitable one. The diagnosis, then, is not just a clinical finding—it is confirmation of a fear they have been carrying for decades.

What patients less often know is that many people with diabetes do gain meaningful control, live full and active lives, and die of something else entirely. That reality is harder to witness than the complications, not because it is rare, but because it is invisible: the well-managed diabetic does not become a cautionary story in the family or the community. The question “do you know anyone with diabetes who is healthy?” opens exactly that gap. It names the schema, surfaces the fear, and creates space for the BHC to offer a different and equally evidence-based narrative—one where the diagnosis is a call to action rather than a sentence. The Contextual Interview framework described by Cahill and colleagues , which anchors a semi-structured assessment of the patient’s life context in the domains of love, work, play, and health behaviors, supports exactly this kind of real-time schema work: understanding not just what the patient knows about their condition but what they believe about it, and how that belief is likely to shape their behavior going forward.

From that foundation, the BHC can begin the assessment and initial planning that defines PCBH work. A functional behavioral assessment in diabetes might ask: What does a typical day look like? Where does self-management fit into it, and where does it break down? What does the patient already do well? What barriers—practical, emotional, social, or structural—stand in the way? The GATHER framework’s emphasis on the Generalist approach is directly relevant here: the BHC is not diagnosing or treating major depression or generalized anxiety disorder in this visit. The BHC is assessing function in the context of a specific illness and supporting the patient’s capacity to navigate it (GATHER: Generalist; 4 Cs: Comprehensiveness—the BHC addresses behavioral function across domains rather than a discrete disorder.).

This contextual picture also determines whether the lifestyle interventions the PCP prescribes have any realistic prospect of success. The BHC who understands a patient’s life context is positioned to intercept recommendations that will fail before they are ever attempted—and to communicate that back to the team before the patient is labeled non-adherent. Consider the practical range of what this looks like. A mother of eight, cooking for her household with cultural foods that have nourished her family for generations, will not prepare a separate low-carb meal for herself each night. A patient who lives in a neighborhood where walking outside is genuinely unsafe will not go on daily walks, however sincerely the recommendation is offered. A person without stable housing, sleeping in a tent, cannot reliably refrigerate insulin formulations that require cold storage. A patient working three jobs, living in a food-insecure household without consistent electricity, will not use a cookbook of healthy recipes. These are not failures of motivation or compliance. They are failures of prescription—recommendations delivered in apparent ignorance of the conditions in which the patient actually lives (more on these types of systemic errors in healthcare in a future post!).

The contextual interview makes this information available at the moment it can still change the plan. When the BHC communicates back to the PCP after the visit—which, in PCBH, happens the same day—the team’s understanding of what is and is not feasible for this patient can reshape the medical recommendations before they harden into a documented treatment plan the patient cannot follow. This is one of the less-discussed arguments for routine BHC involvement at the point of diagnosis: not just that it addresses psychological distress, but that it prevents the accumulation of well-intentioned advice that is structurally impossible to take.

The most fully realized settings extend this principle across the entire care team. A nurse clinician, a registered dietitian, and a clinical pharmacist brought into the care of a newly diagnosed patient—each informed by the same contextual interview—can together produce a treatment plan that actually fits the patient’s life. A dietitian who knows that a patient’s food choices are constrained by culture, cost, and the absence of a working stove will recommend differently than one who does not. A pharmacist who understands that a patient is unhoused can work with the prescriber on formulations and storage solutions that are realistic. The BHC’s contribution is not unique in this regard; it is one strand in a team-based response whose collective goal is a plan the patient can actually follow. How these roles interact in the context of ongoing chronic disease management is a subject large enough to warrant its own discussion, and one I will return to in a future post.

The intervention that follows will vary by patient, but several evidence-based approaches have particular relevance to diabetes care. Acceptance and Commitment Therapy (ACT) adapted for diabetes self-management has strong empirical support. In a randomized controlled trial at a community health center, Gregg and colleagues found that patients with type 2 diabetes who received a combined diabetes education and ACT intervention, compared to education alone, showed significantly better self-management at three months and were more likely to have hemoglobin A1c values in the target range. Mediational analyses indicated that the improvements in A1c were driven by changes in acceptance coping and self-management behavior—findings consistent with the ACT model’s emphasis on psychological flexibility as the mechanism of change. Mindfulness-based approaches have also demonstrated preliminary efficacy in diabetes populations, with DiNardo and colleagues finding significant improvements in diabetes distress, self-efficacy, and A1c among veterans who participated in a mindfulness-integrated diabetes education program.

These are targeted interventions adapted to primary care, not extended courses of individual psychotherapy. The BHC is not beginning ongoing treatment; the BHC is introducing a set of tools, building the patient’s sense of agency, and communicating clearly that behavioral health support is part of the care team’s shared investment in the patient’s health (GATHER: Educator; 4 Cs: Coordination—the BHC’s same-day feedback extends the team’s understanding in both directions, toward the patient and toward the PCP).

Stigma, Framing, and the Offer

The framing of the warm handoff offer matters enormously in diabetes care, and the reason relates directly to the stigma literature. A patient who has just been told they have diabetes is already navigating what that diagnosis means in the context of everything they have absorbed from their social environment about who gets diabetes and why. Offering a BHC visit framed as a response to psychological pathology—”I’d like you to talk to our counselor because this can be a lot to handle emotionally”—may inadvertently confirm a patient’s fear that they are broken or unable to cope.

The more effective framing normalizes the BHC visit as a standard feature of diabetes care, not a response to distress. Language like “everyone who receives a new diabetes diagnosis meets with our behavioral health team member today—they’re part of how we help patients with the full picture of managing this” sends a fundamentally different message. It positions the BHC visit not as a psychiatric referral but as evidence that the care team understands that managing a chronic illness is more than pharmacological .

This is not merely a matter of communication strategy. It reflects the model’s underlying philosophy: that behavioral health is not a specialty to which patients with psychological complications are referred, but a dimension of care that belongs to every patient as a matter of course. Holmes’s argument in Fresh Fruit, Broken Bodies applies here in a different register. Just as illness cannot be separated from the social conditions that produce it, it cannot be treated without attending to the person embedded in those conditions. The warm handoff in diabetes care is the structural expression of that understanding.

Diabetes Is Not the PCP’s Problem

I want to return to the framing with which I began this post, because I think it has direct operational implications.

When behavioral health involvement in diabetes care is treated as contingent—as something that becomes relevant when a patient is also struggling psychologically—it creates a workflow in which the BHC is available but not routinely utilized. PCPs who conceive of diabetes as a metabolic problem will look for behavioral health referral triggers that are behavioral in character: the patient who cries in the exam room, the patient who openly expresses hopelessness about self-management, the patient who admits to avoiding glucose monitoring. These triggers are real, but they capture only the most visible fraction of the psychological burden that diabetes carries.

The research suggests the distribution of distress in this population is far broader than what presents visibly in the exam room. Research in FQHCs—the clinical settings most closely associated with the contexts in which PCBH has developed—finds that approximately 40% of patients with diabetes have comorbid depression, substantially higher than the general population prevalence . This figure does not represent patients who have disclosed depression to their PCPs; it represents the prevalence in the population regardless of disclosure. A PCP whose warm handoff trigger is visible emotional distress will therefore miss the large majority of patients who would benefit from BHC involvement.

The pandemic years made this fragmentation visible in ways that were difficult to ignore. As COVID-19 disrupted routine care delivery, A1c testing rates dropped sharply and patients fell out of monitoring at scale; among those who did maintain follow-up, glycemic control was largely preserved—but the decisive variable was access to medications and continuity of care, not the quality of any individual clinical encounter . What I witnessed at my own clinic was a retrenchment to familiar silos—PCPs managing the metabolic panel, BHCs managing the mood symptoms—even on a team that understood integration. The patients who fared worst were not those whose providers stopped caring; they were those whose access to the system had been severed. A pathway makes that retrenchment structurally harder to fall back on, because the connection is built in before the disruption arrives.

The solution is not to ask PCPs to become better at identifying diabetes distress. It is to build a system in which BHC involvement does not depend on that identification at all. A pathway that delivers a warm handoff to every patient with a new diabetes diagnosis, or to every patient whose A1c exceeds a specified threshold at follow-up, makes shared ownership of the whole patient institutional rather than aspirational—not the PCP’s problem to own and the BHC’s problem to consult on when things get complicated (GATHER: Team-based; 4 Cs: Continuity—a diabetes pathway assigns joint clinical responsibility and preserves the care relationship across disruptions).

A Clinical Note from My Own Practice

After fourteen years at the same clinical site, I have seen many patients with diabetes at the moment of diagnosis and long after it. What strikes me most—still—is how often the presenting issue in those visits is not glycemic management at all. It is the patient who learned about their diagnosis the same week their marriage was ending. The patient who has been eating for reasons that have nothing to do with hunger. The patient who grew up watching a parent lose a limb to diabetic complications and now manages their own diagnosis through a fog of anticipatory grief. The patient who has been living with undiagnosed diabetes for years because they were afraid to go to the doctor.

None of these presentations announces itself as a behavioral health referral. All of them are precisely the clinical territory a BHC is trained to work in. The warm handoff exists, in part, because patients rarely say the things that matter most in a visit designed around something else. A same-day BHC visit creates a different kind of encounter—one whose primary agenda is the patient’s experience rather than their chart. That encounter is not supplementary to good diabetes care. It is an integral part of it.

There is a public health dimension to this work that I cannot let pass without comment, because it bears directly on what the absence of behavioral health integration—and the absence of healthcare access itself—actually looks like in a clinic room.

I began my career before the Affordable Care Act and before Washington State expanded Medicaid. From those years, I carry a memory that resurfaces with some regularity: walking into an exam room and being overwhelmed by the smell of rotting flesh. Patients with uncontrolled, untreated, or undertreated diabetes who lacked insurance or were underinsured had sometimes reached the point of advanced diabetic foot complications before they had any meaningful contact with a medical team. The wound had been developing for weeks or months. They had not come in sooner because they could not afford to.

That experience has become a distant memory since Medicaid expansion. This is not anecdote—it is documented. A cohort study examining over 115,000 hospitalizations for diabetic foot ulcerations among racial and ethnic minority adults found that early Medicaid expansion under the ACA was associated with a 33% decrease in major amputation rates among previously uninsured adults in expansion states, while amputation rates continued to rise in non-expansion states . Limbs were saved because people could finally get through the door before the tissue was gone.

Holmes is writing about farmworkers navigating structural violence in the strawberry fields of Washington State, but the argument applies in any clinic that serves patients whose access to care is constrained by policy. Integrated behavioral health, delivered through the warm handoff, is a meaningful clinical intervention. It operates, however, downstream of the decisions that determine whether patients can access care at all. The deathly smell I remember from those early years is what happens when the structural conditions fail entirely. The warm handoff is an instrument of connection within the clinic. Whether there is a clinic that patients can reach and afford is a question that belongs to all of us.

Conclusion

Holmes’s central insight in Fresh Fruit, Broken Bodies is that medicine’s tendency to locate illness in individual bodies, rather than in the social structures those bodies inhabit, forecloses understanding and treatment alike. The warm handoff in diabetes care is a small structural intervention in that same direction: an insistence that the person sitting in the exam room is more than a collection of metabolic values, that their illness is being produced in conditions the PCP alone cannot fully address, and that the care team owes them not just medical management but the full range of support that integrated care can provide.

Diabetes does not belong to the PCP. The warm handoff is how the team claims shared ownership.
