Patient no-shows: Find the causes before applying solutions

A missed appointment costs a practice far more than the lost billing. It also wastes hours of scheduling and prior authorization work, a health care operations leader said.

Practice leaders can reduce those losses, but only after they take the time to diagnose why their patients aren't showing up, he said. Too often, organizations pile on solutions before they understand the problem.

"The problem is, with a lot of systems, they act first before they investigate and understand what is the problem," said A.G. Ghanim, M.B.B.Ch., healthcare senior manager at the University of Michigan. He also is founder of ZLinQ Consulting, with a six-step process to define, diagnose, prioritize, design, implement and optimize solutions for patient no-shows.

Ghanim, who specializes in workforce optimization and capacity planning and was a presenter at the Medical Group Management Association (MGMA) 2026 Annual Conference, discussed no-shows in a video interview.

Where are the hidden costs?

Most leaders think of a no-show as the revenue that patient would have brought in, Ghanim said. But scheduling and prior authorization teams have already invested hours in every appointment, and much of that work must be redone when a patient doesn't arrive.

In complex specialties that depend on coordinated rooms and teams, one missed patient can disrupt the rest of the day, and some settings, such as early-morning procedures, can't simply overbook. Published research puts average no-show rates worldwide at roughly 23% to 30%, he said.

The losses may be hard to quantify, he said, but staff on the ground feel them. When he managed a pain clinic, the physicians, anesthesiologist and nurses waiting for a 7 a.m. patient who never arrived looked to him, the manager, for answers.

Access suffers as well. When a patient skips a long-awaited specialty appointment, another patient who could have used that slot loses out, too.

"It's a missed opportunity that will never happen, never open again," Ghanim said.

How should leaders diagnose no-shows?

Many organizations come to him after trying reminders and other measures, Ghanim said. His approach begins with three steps aimed at understanding: define the problem, diagnose it and rank the drivers behind it. That can take a few weeks of hard work collecting data.

There is almost never just one cause. Ghanim identifies the most important driver, then the second and third, and works with each organization to decide how many it can tackle with its resources. The more drivers addressed, the better the results. Some fixes cost little, while others call for different resources, depending on the organization. Some clinics he has worked with have gone from a 19% no-show rate to 7% or 5%.

He warned against blaming demographics. Saying patients in a low-income area simply don't show up mistakes a symptom for a cause, he said, and clinics in those areas improved significantly once they investigated.

"You have to bring the data to understand and have to (make) an informed decision based on the data," he said.

Does your structure help or hurt?

Organizational structure shapes how fast a practice can act, Ghanim said. When the scheduling team reports to the manager leading the effort, changes can start right away. In large systems with centralized scheduling, a department leader may have to work through the chain of command, and aligning on a new workflow can take weeks.

Small practices face the opposite problem. They can execute quickly, but they may lack robust electronic health record (EHR) reports or data staff to pinpoint causes. Large systems usually have the data, if leaders ask the right questions.

Once leaders reach what Ghanim called the "aha moment" about their no-show drivers, they usually commit to the fix, and the solutions are often inexpensive. For thin-margin services such as sleep labs, he said, even a 1% or 2% change in the no-show rate can affect income for the whole year.
