Most clinics treat a no-show as lost revenue. In dialysis, a missed treatment is also a clinical event. The patient goes two or three extra days without the treatment that clears potassium and fluid, and the research on what follows is consistent: more hospital admissions and higher mortality. Reminders help, but the bigger gain is often in what happens after the reminder, when the patient needs to move the session.
What the research says about missed treatments
Three large studies give the clearest picture.
| Study | Population | Finding |
|---|---|---|
| DOPPS phase 5 | In-center hemodialysis patients in 20 countries | 24% of US patients missed at least one treatment in four months, the highest share of any country studied. Missed treatments were associated with higher all-cause mortality (HR 1.68). |
| In-center hemodialysis absenteeism | US in-center hemodialysis cohort | Patients missed 9.9% of treatments. About half were absences rather than hospitalizations, and a single absence was associated with 1.4 times the risk of hospitalization and 2.2 times the risk of death in the next 30 days. |
| Adherence barriers to chronic dialysis | 182,536 US patients, 44 million treatments | Hospitalization odds were about four times higher in the two days after a missed treatment. Transportation, weather, holidays, pain and illness were among the barriers linked to missed days. |
These are observational studies, so they show association rather than proof that each missed session causes harm. Even so, the pattern is the same in every dataset, and the third study points at something useful for operations: many missed days have ordinary causes. A ride that falls through and a holiday schedule change are logistics problems, and logistics problems are the ones a front desk can help with.
What reminders can fix
The best general evidence on reminders comes from a Cochrane review of mobile phone messaging reminders. Across the trials it pooled, attendance was 67.8% with no reminder, 78.6% with text reminders, and 80.3% with phone call reminders. Text and phone reminders performed about the same, and texts cost less per attendance.
Two caveats keep that in proportion. The trials covered healthcare appointments in general, not dialysis specifically. And the evidence was rated low to moderate quality. So reminders are worth doing, but nobody should promise a dialysis unit a specific reduction in missed treatments from reminders alone.
Reminders work best on the patient who forgot or got the day wrong. Dialysis patients usually keep a fixed schedule for months, so plain forgetting is less of a problem than it is for a once-a-year visit. The reminders that matter most fall around schedule changes: holidays, a moved shift, a temporary chair at another unit, or the first weeks after a patient starts treatment.
What reminders cannot fix
A reminder does nothing for the patient who knows about the session and cannot get there. That patient needs to move the treatment, and moving it takes a phone call.
A missed session can start like this. The patient calls at 6 a.m. because their ride cancelled, reaches a recording, and never calls back. Or they call during a shift change, wait on hold, and hang up. Nobody reschedules the session, and the first time anyone notices is when the chair sits empty.
So the operational question has two parts. Did we remind them? And when they needed to change the plan, could they reach someone who could change it?
A workable reminder and rescheduling setup
None of these steps is new. They work best when each one leads to the next.
- Remind around change, not only on a timer. Send a reminder when something differs from the routine: a holiday week, a shift move, a new location, a first treatment.
- Make every reminder answerable. A reminder the patient cannot reply to is a broadcast. Give them a number that is answered at the hours they actually call, including early mornings.
- Reschedule on the first call. Whoever answers should be able to offer the open options inside the unit’s rules, or hand the request to staff with the reason and the patient’s details already captured.
- Follow up the same day on misses. If a patient misses a session without calling, a same-day call to find out why and to offer the next slot beats a note in a queue.
- Send clinical questions to clinical staff. A patient who says they feel unwell is not a scheduling request. That call goes to the care team’s escalation path immediately, with the clinical judgment left to clinicians.
- Track the reasons. Record why sessions were moved or missed. If transport comes up again and again, the fix may be a transport conversation, not more reminders.
Where EigenH AI fits
EigenH AI works with nephrology practices on the phone and follow-up side of this problem.
- The Scheduler answers calls at any hour and schedules or reschedules inside rules your office approves. Requests outside those rules go to staff with the caller’s context.
- The Recaller works missed calls and approved follow-up lists on the channels your office chooses, so a patient who missed a visit gets a call back instead of waiting on a list.
- Anything clinical, urgent, or outside the approved workflow goes to the practice’s escalation path. The agents do not triage symptoms or give medical advice.
One limit to state plainly: dialysis chair schedules often live in the dialysis provider’s system rather than the practice’s. What the Scheduler can change depends on which systems it is connected to, so ask us what is realistic for your setup before assuming it covers chair time.

Start with last month’s misses
Pull last month’s missed sessions and appointments and sort them by reason, as far as you know it. Count how many involved a call that went unanswered or a patient who could not reach anyone to reschedule. That number is the part of the problem reminders alone will not touch. If it is larger than you expected, book a demo and we will walk through which of those calls EigenH AI would have answered and where it would have handed off to your team.
