Can Lung Nodule Tracking Systems Reduce Delayed Cancer Diagnosis?

A spot shows up on a CT scan. It is small, smaller than a pea, and the radiologist’s report includes an easy-to-miss line recommending another scan in six or twelve months.

This is one of the best-documented patient safety gaps in American medicine. The radiologist usually did the job: saw the nodule, described it, and wrote down what should happen next.

The failure comes afterward, in the handoff between the person who read the scan and the people responsible for acting on it.

This article explains why those handoffs break down, what nodule tracking systems are designed to do, who is responsible when follow-up never happens, and when that gap becomes a lung cancer malpractice claim in New York.

What a Nodule Tracking System Does

A tracking system’s job is simple: make sure a written recommendation turns into a completed scan, without relying on anyone’s memory. Hospitals do this in a few ways:

• Software that reads radiology reports. It flags any report that recommends nodule follow-up and creates a task in the chart.

• A nodule registry. A nurse navigator or care coordinator keeps a running list of every patient with a scan coming due and reaches out directly.

• A lung nodule clinic. Pulmonologists and nurse navigators take over follow-up once a nodule is reported, instead of leaving it to whichever doctor ordered the original scan.

• Structured report language. A standard phrase, such as a specific Fleischner category with a follow-up date, makes recommendations easier to track and harder to bury.

The best programs combine several of these. They also “close the loop,” meaning someone confirms the follow-up scan actually happened instead of assuming it did.

The follow-up intervals these systems track come from the Fleischner Society’s guidelines for incidental nodules, which set timelines based on the nodule’s size, type, and the patient’s risk.

Our article on why nodule size alone shouldn’t decide follow-up explains those intervals in detail.

Who Owns the Follow-Up?

When a recommendation goes nowhere, families naturally ask who was supposed to act. The honest answer is that responsibility is often shared, and that sharing is part of the problem. Depending on the facts, it can fall on:

• The radiologist, if the recommendation was vague (such as “clinical correlation advised”) instead of specific about when and how to follow up, or if a finding that warranted direct communication was never communicated.

• The ordering physician, often in the emergency room or hospital, who received the report and had a duty to tell the patient about the finding or to make sure someone would follow up after discharge.

• The primary care doctor, if the report reached their office and no one acted on it, or if the nodule went unmentioned across later visits.

• The hospital or health system, if it had no reliable process for tracking recommended follow-up, or had one that broke down. A hospital can also be responsible for the negligence of the doctors and staff it employs.

When each party assumes someone else will handle it, a gap opens. Expert review of the records usually shows where that gap was.

How Often Follow-Up Falls Through in New York Hospitals

Researchers at NYU Langone studied what happened to patients with incidental lung nodules before and after the health system added structured follow-up recommendations and electronic tracking. Before the change, 40% of patients were lost to follow-up. Afterward, the share dropped to 29.5%, and completed follow-up rose from 56.6% to 75%.

That is real progress, and it shows the problem is fixable. It also means that even at a major academic medical center with a tracking program in place, nearly three in ten patients still didn’t get the follow-up they needed.

The researchers found that patients seen in the emergency department or admitted to the hospital were among those least likely to complete follow-up. Older patients and nonwhite patients were also less likely to complete it.

The scale matters. Leaders of the American College of Radiology have noted that incidental lung nodules make up roughly 40% of all actionable incidental findings on imaging. They have also noted that more than half of lung cancers are diagnosed in people who are not in a lung cancer screening program. For many patients, an incidental nodule is the only early warning they will get.

Why a Correct Recommendation Can Still Go Nowhere

Most lung nodules that end up in these cases are incidental. They show up on a CT scan ordered for something else entirely, such as a car accident workup, a scan for chest pain or a suspected blood clot, or an abdominal CT that happens to include the bottom of the lungs.

That origin creates the problem. The doctor who ordered the scan is often an emergency physician or a hospitalist who will never see the patient again. That doctor was focused on the reason for the visit, not a small spot in the corner of the image. The radiology report may run several paragraphs, with the nodule recommendation near the end.

A small nodule is also not treated as a “critical result.” Hospitals have strict protocols for calling a doctor immediately about an urgent finding, such as a collapsed lung or a large blood clot. A nodule that needs a scan in six months does not trigger that phone call. It falls into a middle category of findings that matter but are not urgent. That middle category is where tracking either exists or doesn’t.

So the recommendation can sit in a chart where no one is looking. The primary care doctor may never receive the report. The patient may never be told a nodule was mentioned at all.

If You Were Told “We’ll Keep an Eye on It”

If a doctor once mentioned a spot on your lung and you are not sure anything came of it, start with the records:

• Request the full radiology report, not a summary. Look for the word “nodule” and any recommended follow-up interval or Fleischner category.

• Note who ordered the scan and where. An emergency room or hospital scan is the setting where follow-up most often falls through.

• Check your patient portal. See whether the report was released to you, and whether any message or letter mentioned follow-up.

• Look at what happened next. Check for a scheduled scan, a referral to a pulmonologist or lung nodule clinic, or any mention of the nodule at later visits.

If months or years passed with no follow-up and no explanation, that gap is worth a professional review. That is true whether or not cancer has been diagnosed.

Frequently Asked Questions

Who is responsible for scheduling follow-up on an incidental lung nodule?

Responsibility can fall on several people. The ordering physician, often in the emergency room or hospital, generally must tell the patient or arrange follow-up. The primary care doctor must act on reports they receive. The hospital may be responsible if it had no reliable system to track recommended follow-up scans.

How often are incidental lung nodule follow-ups missed?

Often. At NYU Langone, 40% of patients with incidental lung nodules were lost to follow-up before the health system added structured recommendations and electronic tracking. Even afterward, nearly 30% were lost, with emergency and hospitalized patients among those least likely to complete their recommended scans.

What is a lung nodule tracking program?

A lung nodule tracking program is a system that turns a radiologist’s follow-up recommendation into a completed scan. It may use software that flags reports, a registry managed by a nurse navigator, or a dedicated lung nodule clinic. Strong programs confirm each scan actually happened instead of assuming it did.

Can a hospital be held liable for failing to track a lung nodule follow-up?

Possibly. A hospital can be responsible for negligence by the doctors and staff it employs, and its tracking processes may be examined when a written follow-up recommendation was never acted on. Liability depends on the records, who received the report, and whether the delay changed the cancer’s outcome.

Does continuing to see the same doctors affect the New York filing deadline?

It can. Under CPLR 214-a, the deadline for a delayed cancer diagnosis claim runs from the later of when you discovered the mistake or your last continuous treatment for the condition. Ongoing care for the same problem may delay when the clock starts, subject to a seven-year outer limit.
