Physicians Unaware of Nodule on Routine X-ray

Description

A 64-year-old man died from lung cancer nearly two years after X-rays in the ED revealed an incidental finding of a lung nodule that was never followed.

Key Lessons

  • Miscommunication of abnormal test results and failure to designate a service for follow up can lead to serious patient consequences.
  • A clear process for notifying the responsible service is needed to ensure adequate communication of important incidental findings.
  • Office practice processes must be developed to ensure that the PCP receives and views all abnormal test results relating to his or her patients.
  • Thorough review of tests and adequate documentation in the medical record help establish physician credibility when defending against subsequent allegations of negligence.

Clinical Sequence

On December 23, 1999, a 62-year-old man was evaluated in the ED for neck and shoulder injuries following a motor vehicle accident. He was a one pack/day smoker for many years, and had a past medical history of depression and low back pain. Workup included a left shoulder and chest X-ray, which the ED physician read as showing no fracture or other significant findings. The patient was discharged home with a diagnosis of shoulder contusion and neck pain.

Four days later, a radiologist performed the final interpretation of the X-rays, noted a nodule in the left lung and recommended follow up. Per routine departmental procedure, a copy of the radiology report was faxed to the ED and a copy was sent via inter-office mail to the PCP. The radiologist did not call either the PCP or the ED to communicate this incidental finding.

On January 21 and 31, 2000, the patient saw his PCP for symptoms of back and shoulder pain related to his accident. He was referred to PT and orthopedics. Documentation from those visits does not indicate that the X-rays from the earlier ED encounter were present and/or reviewed by the PCP.

In August 2001, the patient presented to the ED with complaints of chest and shoulder pain. A chest-X-ray was performed and read as normal by the ED attending. After the patient was discharged, the final reading of this X-ray was abnormal, with a large mass in the left lung. The patient was not made aware of this finding. The PCP was not on call when this event occurred; it is unclear whether or not this finding was communicated to the covering physician.

In September 2001, the patient saw his PCP for muscular pain. He was sent to Radiology for a shoulder X-ray, which was normal. Treatment included continuation of pain killers and physical therapy.

On October 17, 2001 the patient presented to the ED with complaints of intermittent back and chest pain. A chest-X-ray showed 75 percent white-out, indicating pneumonia or a possible mass on the left lung. The patient was admitted to the hospital where a CT scan revealed a left hilar mass with metastases. Subsequent CT scans of his abdomen and head/ brain revealed metastatic disease.

His condition deteriorated quickly and he died within a week.

Allegation

The patient’s children sued the ED physician, radiologist, and PCP, alleging failure to identify and follow up on a lung nodule, resulting in the patient’s death from lung cancer.

Disposition

The case was settled in the high range (> $500,000)

Analysis

Clinical Perspective

  1. Although each service operated strictly within the expectations of its domain, the PCP was unaware of an important incidental finding. Neither the radiology nor emergency departments had reliable processes to ensure communication of this finding to either the PCP or the patient.
    Establishing protocols for who is responsible for ensuring the communication of an incidental X-ray finding to the appropriate physician for follow up can avoid the problem of “no one” being responsible. Independent services need to collaborate to clarify responsibility, set clear expectations, and develop reliable and verifiable processes to assure that worrisome test results are brought to the attention of the PCP. Validation that they have been received by the PCP (or covering physician) is a critical step to ensure that results have been received and seen by the appropriate parties. Designated staff may be assigned to manage the process, thereby reducing physician workload while ensuring completion of the process and minimizing risk.

Patient Perspective

  1. This patient presented to multiple providers, including his primary care provider, with back and shoulder pain. From his perspective, he was acting appropriately, both in seeking emergency care and following up with his PCP at the right intervals. He expected that all information obtained in the ED would be available and reviewed by the primary care physician as part of his examination. His family contended that the PCP’s failure to obtain and review the findings resulted in a delay in his diagnosis and treatment—and potentially reduced his life expectancy.
    Most patients are unaware of the complexities of ensuring that diagnostic tests reach the appropriate provider, and—not unreasonably— expect that the clinician will review the relevant information prior to determining a treatment plan. From the patient perspective, all relevant information should be readily available to the treating provider and it is the responsibility of the treating physician to have the appropriate information at the time of the visit. Development of both hospital and office-based processes are necessary to ensure that this expectation can be met.

Risk Management Perspective

  1. Lack of a process to ensure provider review of all incoming test results and review of this patient’s chart in the office created several missed opportunities for earlier diagnosis and treatment of this cancer.
    PCPs are responsible for overseeing their office-based processes. They need to be involved in the development and oversight of test result management systems within their office practice in order to assure that they view all relevant test results without fail. Physicians cannot act on abnormal results that they don’t see. The presence of a radiology report in the patient’s chart that was filed without the PCP’s review indicates a failure in the test result management process.

Legal Defense Perspective

  1. Expert reviewers for the defense could not support the physician’s documentation practices nor his admittedly inconsistent practice of reviewing the record prior to the visit.
    Review of previous notes and test results prior to the patient’s visit is essential to making a full patient assessment and timely diagnosis. Documentation should always include clinical rational for decision-making and a prescribed treatment plan. Scant documentation of a patient’s history or the components of the evaluation not only undermines subsequent care; it may contribute to a perception of inattention to detail and a lack of credibility in any subsequent litigation.
