Field Notes Series: The Last Mile
Entry #2 of 6
Disclaimer
Field Notes reflect the editorial analysis of the Managing Editor, informed by direct professional experience across Caribbean healthcare systems. These observations surface recurring structural patterns and do not represent the official positions of any government, institution, or commercial partner.
A patient leaves.
Not the building. Not the ward. The system.
They cross a border, board a flight, walk into a facility in another country — or simply leave one provider’s office and find their way to the next. And in that movement, something critical happens that most Caribbean health systems are not yet designed to prevent:
The thread breaks.
Not dramatically. Not with an alarm or an incident report. It breaks quietly, in the space between one provider’s notes and another’s intake form. In the gap between what was known and what was communicated. In the distance between where care was given and where it continues.
That gap has a name: a failure of care coordination.
What Care Coordination Actually Means
Care coordination is not a scheduling function. It is not a referral letter. It is not the act of sending a patient from one place to another with a phone number and a hope.
It is the deliberate organization of patient care activities and the sharing of information among all participants concerned with a patient’s care — so that the right care is delivered safely, at the right time, in the right place.
That definition belongs to the Agency for Healthcare Research and Quality. It is not aspirational language. It is an operational standard — one that high-functioning health systems have built infrastructure around for decades.
The core competencies of care coordination are well established in the literature and in internationally recognized reference frameworks. They include a shared care plan that travels with the patient, medication reconciliation at every transition point, a designated care coordinator or lead clinician who holds accountability across the continuum, structured communication between sending and receiving providers, and a feedback loop that returns information to the originating system once care is delivered elsewhere.
These are not luxury features. They are the minimum conditions under which patient movement does not become patient risk.
In much of the Caribbean, they are inconsistently present.
The Scene
Consider what patient movement actually looks like across the region.
A patient managed for hypertension and early-stage kidney disease in a primary care setting is referred to a nephrologist — visiting, available once a month, operating from a list that was compiled before the patient’s last set of results came back. The specialist sees the patient once. A letter is generated. It may or may not reach the referring physician. The patient returns to their regular provider carrying what they remember from the consultation.
That same patient, when their condition progresses, is referred off-island. They travel to a tertiary facility in a neighboring country. The receiving team has what was sent — a summary letter, perhaps a set of labs. They do not have the full clinical history. They construct a picture. They treat what they can confirm. The patient returns home with a discharge summary that must now be reconciled with a local record that has continued to evolve in their absence.
At no point in this sequence is there a single coordinating intelligence — a person, a system, or a protocol — that holds the whole patient.
This is not a transport problem. It is not a specialist availability problem. It is a care coordination problem. And it is structural.
The Regional Reality
The Caribbean’s fragmentation is not incidental. It is geographic, economic, and political.
Small island states cannot replicate the full spectrum of care within their borders. Cross-border patient movement is not a system failure — it is a rational and necessary adaptation. What is not rational, and not necessary, is the absence of coordination infrastructure around that movement.
The region operates, in effect, as a collection of markets. A patient who travels from one territory to a neighboring island to a regional hub and back is moving through distinct health system environments, each with its own records infrastructure, its own clinical culture, its own understanding of what the patient needs. The patient becomes the carrier of their own history — and when memory, language, or health literacy limits that capacity, continuity fractures.
The Joint Commission International, the Pan American Health Organization, and regional guidance bodies have all identified care transitions as a primary locus of adverse events. Medication errors, duplicated diagnostics, missed diagnoses, and treatment gaps cluster disproportionately at the points where patients move between providers or systems.
The Caribbean, by virtue of its structure, produces more of those transition points per patient than almost any comparable region in the world.
The Guideline Gap
Care coordination frameworks exist. They are not theoretical.
The Chronic Care Model, developed by Wagner and colleagues, provides a validated structure for managing patients with complex conditions across providers and settings. The Patient-Centered Medical Home model establishes the primary care practice as a coordination hub, responsible for the patient’s full care experience regardless of where individual services are delivered. Transitional care models — including the Coleman Care Transitions Intervention and the Naylor Transitional Care Model — provide evidence-based protocols specifically designed to govern what happens when patients move between care settings.
These frameworks have been adapted and implemented in resource-limited settings. They do not require technology infrastructure that the Caribbean does not have. They require accountability, defined roles, and the institutional will to treat coordination as a clinical function rather than an administrative afterthought.
The question for the region is not whether the frameworks exist.
It is whether any Caribbean health system has formally adopted one — and built the workforce competencies, the documentation standards, and the accountability structures to make it operational across the care continuum.
In most cases, the honest answer is: partially, inconsistently, and without measurement.
What’s Really Happening
When care coordination is absent or informal, three conditions define the system.
The Patient Becomes the Record
In the absence of shared care plans and structured handoff documentation, patients carry their history in their memory. They report medications they may misremember. They describe diagnoses they may have partially understood. They present to new providers as a summary of what they recall — and the clinical picture that emerges is only as complete as what they were able to hold.
Transitions Become Restarts
Every move between providers, facilities, or systems that is not governed by a structured handoff protocol is effectively a new intake. The receiving provider starts from what they have, not from what was known. Diagnostic work is repeated. Medication reconciliation is approximate. The efficiency of the prior clinical investment is partially lost.
Accountability Diffuses Across the System
When no single provider or structure holds coordination responsibility across the continuum, accountability for the patient’s full care experience belongs, in practice, to no one. Individual providers are accountable for their episode. No one is accountable for the thread.
This is not a failure of clinical competence. The Caribbean has capable clinicians across every territory. It is a failure of care system design — and the distinction matters, because one can be solved by training individuals, and the other requires building something that does not yet exist.
The Last Mile Insight
The referral is not the end of care. It is a transition.
And transitions without coordination infrastructure are not handoffs. They are releases — into a system that was not designed to receive what the sending system knew.
In the last mile, movement is among the highest-risk moments in the care continuum. Not because the region lacks the will to move patients. But because the architecture of care coordination — the shared plans, the designated accountability, the structured communication, the feedback loops — has not been built at the level the region’s geography demands.
Patients don’t disappear because no one cares. They disappear because no system was designed to hold them.
🔍 Process Check
• Is there a formal care coordination framework? → Rarely adopted at system level
• Are shared care plans standard at transitions? → Inconsistently
• Is medication reconciliation structured at handoff? → Variable
• Is there a designated coordination lead across the continuum? → Seldom defined
• What breaks it? → Absent accountability structures, fragmented records, market-by-market operation, no feedback loop between sending and receiving systems
Closing Note
Care coordination is not a concept the Caribbean is unfamiliar with.
It is a competency the region has not yet systematically built.
The frameworks are available. The evidence is established. The need — given the region’s geography, its patient movement patterns, and its chronic disease burden — is arguably greater here than in most comparable health system environments in the world.
What remains is the institutional decision to treat coordination not as a support function, but as a clinical priority. To build the roles, the standards, the documentation, and the accountability structures that allow a patient to move — across a corridor or across an ocean — without losing the thread of who they are and what they need.
Until that decision is made, the system will continue to work.
But it will work around the patient. Not for them.
