There is a moment most Care Partners recognize.

You are sitting in the cardiologist’s office and the nephrologist’s latest labs are not in the chart. Or the specialist asks about a medication that was changed two appointments ago, and you are the one who has to explain it. You have come prepared. The system has not.

This is not an exception. It is how the system operates for most people managing cardiovascular, kidney, and metabolic (CKM) conditions.

Three Conditions, Three Specialists, One Care Partner

CKM conditions do not exist in isolation. Cardiovascular disease, chronic kidney disease, and metabolic conditions such as diabetes are deeply interconnected. A change in kidney function affects heart function. Blood sugar management affects both. What happens in a nephrology office has direct bearing on what a cardiologist needs to know.

The care system is not structured to reflect that reality. It is organized by specialty. Each provider manages their domain. Information travels by referral, when it travels at all. The burden of connecting those domains falls on whoever is present at every appointment, following every thread.

For most families managing CKM conditions, that person is the Care Partner.

What the Research Shows About Specialist Communication

The communication gap between specialists is not a new problem, and attempts to close it have had limited results.

A 2024 viewpoint published in JAMA Internal Medicine cited a national study in which 34% of primary care physicians reported that they do not always, or even most of the time, receive useful information from specialists about the patients they have referred. That figure exists despite widespread adoption of electronic health records, which were expected to improve information sharing significantly. The same source reported that 35% of Medicare beneficiaries saw five or more physicians in 2019.

The consequences of that fragmentation extend beyond inconvenience. Research published in the American Journal of Managed Care found that Medicare beneficiaries with a moderate number of chronic conditions and highly fragmented care were significantly more likely to visit the emergency department or be admitted to the hospital than those whose care was better coordinated (Kern et al., 2018). The connection between providers who are not communicating and patients who end up in crisis is documented. It is not speculative.

For someone managing a condition that involves a cardiologist, a nephrologist, an endocrinologist, and a primary care provider, the fragmentation is not theoretical. It is the appointment schedule.

The Work That Has No Title

When providers are not communicating with each other, someone has to carry the information forward.

That work involves knowing which labs were drawn at which appointment, understanding what one specialist’s recommendation means in the context of another’s, tracking when those recommendations conflict, and deciding what to surface and to whom. It requires preparation before appointments and follow-through after them. It requires holding the full clinical picture, either in working memory or in writing, and presenting the relevant parts to each provider at the right moment.

None of this is casual. It is not simple. And almost none of it is recognized as skilled work by the system that depends on it.

The term that fits this function is coordination. Care Partners managing CKM conditions are performing care coordination without a title, without formal training in it, and without support from the system that has, in practice, assigned it to them by default.

Operating Inside a System That Won’t Coordinate for You

The coordination gap is a structural problem. Care Partners did not create it, and no individual action resolves it at the system level. What is within your control is how you operate inside it.

That starts with documentation. A centralized, current record of your loved one’s medical history, medications, diagnoses, and provider contacts does more than prevent errors at emergency visits. It gives you something concrete to place in front of any provider who does not have the full picture.

Preparing specifically for each appointment, with the relevant specialists’ recent findings in hand, closes some of the communication gap that providers are not closing themselves. Bringing a written summary of recent changes, current medications, and the questions that sit at the intersection of multiple conditions makes the coordination work visible, even when the system does not.

Recognizing what you are actually doing also matters. Not because naming it changes the system, but because understanding the function you are serving changes how deliberately you can manage it.

The coordination tax is real. It accumulates in time, attention, and cognitive load, and it falls on the person who shows up to every appointment in every specialty carrying the information the system has not found a way to share.

You have been paying it. Most Care Partners in your position have. What changes when you name it is how intentionally you can carry it.
