Why care plans stall between visits

Most of a chronic or specialty care plan is carried out between appointments, in refills, home readings and scheduled returns that no single team owns. Leading health systems are managing patient engagement between visits as a set of owned obligations, with the right care team member following up when a plan begins to drift.

a day in missed visits across a 40-clinic network

What is at stake

A 15 percent no-show rate across 40 specialty clinics can leave about 600 appointment slots empty every clinic day.

Where days are lost
  1. Visit to plan
  2. Plan to patient
  3. Patient signal back to the care team

Health systems organize their operations around the visit. Schedules, staffing models, documentation and reimbursement all treat the encounter as the unit of care, and the electronic health record (EHR) is built to capture what happens inside it. Yet for a patient with diabetes, heart failure or depression, the visit is a short checkpoint in a plan that is carried out almost entirely at home, through refills, home monitoring, check-ins and scheduled returns that no single team owns.

The scale of that unowned work is large. About 6 in 10 US adults live with at least one chronic disease and 4 in 10 live with two or more, and chronic disease is a leading driver of the nation's $$4.1 trillion in annual health care costs.1 Each of those patients generates obligations between visits, and most of them sit in the gaps between scheduling, pharmacy, the patient portal and the care coordinator's call list. The sections that follow trace where a care plan loses days after the patient leaves the clinic, what those days cost a specialty network and how patient engagement can be run as an accountable operation.

The gap between visits widens as demand outpaces clinical capacity

Missed appointments and missed doses remain the most persistent leaks in outpatient care. In England, hospital outpatient services recorded 8.0 million appointments in 2023 to 2024 at which the patient did not attend, out of 135.4 million in total.2 In the United States, about one in five new prescriptions is never filled and about half of filled prescriptions are taken incorrectly, and a 2017 CDC review put the direct cost of nonadherence at $$100 to $$300 billion a year.3 The World Health Organization reached a similar conclusion in a foundational 2003 report, which found that adherence to long-term therapies in developed countries averages only 50 percent.4

The capacity to close these gaps is shrinking. The AAMC projects a shortage of up to 86,000 physicians in the United States by 2036, with an aging population driving demand for specialists in particular.5 Patients, meanwhile, expect to reach their care team digitally, and a JAMA study found that patient-written portal messages rose 153 percent between 2020 and 2025, to 2.5 messages per patient per year.6 Each of those messages lands in a clinical inbox alongside refill requests and abnormal home readings, often without a named owner or a deadline for the reply.

Patient engagement breaks down at three handoffs between visits

No-shows concentrate in the specialties that manage long-term conditions. In a widely cited 2018 systematic review of no-show studies, median rates reached 36.0 percent in endocrinology and 30.0 percent in cardiology, against 17.0 percent in pediatrics and 11.2 percent in other specialties.7 Each missed return is the visible end of a chain of handoffs, and three of them account for most of the days a care plan loses.

Endocrinology and cardiology clinics, which run long-term care plans, report median no-show rates of 30 to 36 percent.

01Visit to plan

At the end of a consultation, the plan is split across an EHR note, a referral order, a prescription and a verbal instruction to return in three months. Scheduling, pharmacy, diagnostics and the care coordinator each receive a fragment, and the return visit is often left for the patient to book. When nobody owns the booking, the follow-up lapses without any system recording a missed obligation.

02Plan to patient

Between visits, the patient carries the plan alone through refills, home blood pressure or glucose readings, pre-visit tests and changes in dose. Reminders arrive from separate systems by SMS, portal, phone and pharmacy app, and none of them knows whether the prescription was filled or the instruction understood. Poor medication adherence and appointment no-shows are then recorded as patient behavior, although an unconnected sequence of messages is often part of the cause.

03Patient signal back to the care team

When a patient reports a side effect, misses a refill or sends an out-of-range reading, the signal enters a shared inbox, a call center queue or a device dashboard. A nurse, a pharmacist and the physician may each see part of it, while the obligation to respond has no owner and no deadline. The plan can drift for weeks before the signal reaches the person who is able to adjust it.

AI-native patient engagement routes each follow-up to an accountable owner

Leading health systems are beginning to manage the period between visits as a set of obligations, each with an owner, a deadline and a cost for every day it stays open. A live layer reads the systems already in use, including the EHR, scheduling, pharmacy feeds, the CRM, call center notes, the patient portal and messaging channels such as SMS and WhatsApp, and runs a four-step loop:

  1. Detect

    a drifting plan as soon as the evidence appears, such as a three-month return that is still unbooked two weeks after the consultation.

  2. Explain

    what the gap puts at risk, from a missed titration step to a lapsed referral, with the source note, order or message attached.

  3. Recommend

    the next step and the right person to take it, such as a pharmacist call for a missed refill or a nurse review for an abnormal reading.

  4. Execute and track

    each follow-up until the patient is booked, refilled or reviewed, measuring the share of obligations that close on time.

The same record can give patients one conversational place to confirm appointments, ask questions and report how they are doing, answered from their own care plan and handed to a named care team member when judgment is needed. Pharmacies, home health agencies, referring physicians and payers may see the obligations that involve them, within the permissions the health system sets. Artificial intelligence does the reading, linking and drafting of messages and summaries, while clinicians and care coordinators remain accountable for every clinical decision and every conversation that changes the plan.

Missed visits and lapsed follow-ups can cost a 40-clinic network about $$180,000 a day

Cost of delay in care delivery is the daily financial exposure created when a scheduled visit, refill or follow-up obligation goes unmet, including lost clinic capacity, forgone downstream care and the staff time spent recovering it.

A 15 percent no-show rate across 40 specialty clinics can leave about 600 appointment slots empty every clinic day.

Source: Segeta estimate based on Kheirkhah et al., BMC Health Services Research, and Dantas et al., Health Policy; assumptions are illustrative.

On these assumptions, 30 clinic days at the current no-show rate cost the network about $$5.4 million and 60 clinic days about $$10.8 million, before the clinical cost of patients whose heart failure or diabetes deteriorates outside the plan. Overbooking, waitlists that backfill late cancellations and patients who rebook on their own may offset part of the capacity loss. They do little for lapsed follow-ups, which leave no empty slot and therefore rarely appear in any operational report.

What chief medical officers and care coordination leaders can do now

  1. 01Name an owner for every return visit

    Make booking the next visit, referral or test the responsibility of a named team before the patient leaves, and track the share of care plans that have one.

  2. 02Count lapsed follow-ups alongside appointment no-shows

    Report advised returns that were never booked, because they leave no empty slot and stay invisible in standard scheduling reports.

  3. 03Route patient signals by clinical role

    Send refill gaps to pharmacists, abnormal home readings to nurses and plan questions to care coordinators, each with a response deadline.

  4. 04Give patients one channel across the journey

    Consolidate reminders, questions and confirmations into one conversation that knows the patient's plan and hands off to a named person when judgment is needed.

  5. 05Price each open obligation per day

    Attach a daily cost to unbooked returns, unfilled prescriptions and unanswered signals, so care coordination is staffed and funded against the value it protects.

Health systems cannot hire clinicians fast enough to close the gap between visits through effort alone, yet they can control how quickly a drifting plan reaches someone who can act. Networks that manage every follow-up as an owned, priced obligation are likely to fill more of their clinic capacity, see steadier medication adherence and give clinicians a smaller and better-sorted inbox.

Questions leaders ask

What is patient engagement between visits?

Patient engagement between visits is the work that keeps a care plan moving after the patient leaves the clinic, including refills, home monitoring, check-ins, pre-visit tests and booked returns. In most health systems this work spans scheduling, pharmacy, the patient portal and care coordinators, so it often has no single owner and slips without anyone recording a missed obligation.

Why do patients miss follow-up appointments?

Research links no-shows most often to long lead times between booking and the visit and to a history of previous no-shows, with younger age, lower income, distance from the clinic and lack of private insurance also associated. Operational causes matter as well, because many return visits are left for patients to book and reminders arrive from unconnected systems.

How much does a missed medical appointment cost?

Estimates vary by setting. A study at a US Veterans Affairs medical center put the cost at about $$196 per no-show in 2008 dollars. On illustrative assumptions, a composite network of 40 specialty clinics with a 15 percent no-show rate could lose about $$180,000 a day once lapsed follow-ups and rebooking time are included.

How can health systems improve medication adherence?

Health systems can treat each refill and dose change as an obligation with an owner and a deadline. That means detecting unfilled prescriptions from pharmacy data, routing gaps to a pharmacist or nurse, giving patients one channel for questions and tracking each follow-up to closure. The CDC estimates that about one in five new prescriptions is never filled.
