Objectives: Incidental findings found on computed tomography (CT) scan during the Emergency Department evaluation of trauma patients are often benign, but their presence must always be communicated to patients, who should be referred for follow-up care. Our objective was to quantify the frequency of these incidental CT findings in trauma patients. A secondary goal was to determine how often these lesions were communicated to patients and how often patients were referred for follow-up. Methods: We performed a retrospective chart review of 500 consecutive patients presenting as trauma activations. Subjects received head, chest, or abdomen/pelvis CT scans at our hospital. Patients were identified using our trauma registry. Final CT reports were examined and discharge summaries were reviewed for basic demographics. Scans with incidental findings prompted detailed secondary review of discharge summaries to determine follow-up. Investigators reviewed incidental findings and classified them into three groups by clinical importance, using predetermined criteria. Results: Of the 500 patient charts identified for review, 480 (96%) were available, yielding 1930 CT reports for analysis. Incidental findings were noted in 211 of 480 (43%) patients and on 285 (15%) of the 1930 CT studies performed for the 480 patients. Of available patient records, only 27% of patient charts had mention of the finding in the discharge summary, had documentation of an in-hospital workup, or had documentation of a referral for follow-up. Most-concerning lesions, such as suspected malignancies or aortic aneurysms, accounted for 15% of all incidental findings and were referred for follow-up in only 49% of cases. Conclusions: Incidental findings were noted in 15% of trauma CT scans. Follow-up was poor, even for potentially serious findings. Further studies should examine the long-term outcome of patients with these findings.

Adrenal incidentalomas, defined as masses discovered incidentally during imaging investigation of non-adrenal disorders, have become a rather common finding in clinical practice. The prevalence is not well characterized and varies among studies. The aim of the present study was to perform a prospective evaluation of the prevalence of adrenal incidentalomas among subjects undergoing computerized tomography (CT) scan of the chest in a screening program of lung cancer (Tic TAC study) in Piedmont, a...

PURPOSE: To retrospectively determine the frequency and spectrum of findings and recommendations reported with whole-body computed tomographic (CT) screening at a community screening center. MATERIALS AND METHODS: This HIPAA-compliant study received institutional review board approval, with waiver of informed consent. The radiologic reports of 1192 consecutive patients who underwent whole-body CT screening of the chest, abdomen, and pelvis at an outpatient imaging center from January to June 200...

Abstract Background Limited reports exist about intracranial incidental findings on computed tomography (CT) imaging. We studied the frequency of incidental findings on 3000 brain CT scans of trauma patients. Methods Three thousands standard brain CT scans of trauma patients were evaluated for some incidental findings. Cisterna magna was evaluated in 1500 CT scans. Results In this study we found 30 incidental abnormalities that include 8 cases of tumor: 3 meningioma, 2 craniopharyngioma, 1 oligo...

PURPOSE: To report results of a 5-year prospective low-dose helical chest computed tomographic (CT) study of a cohort at high risk for lung cancer. MATERIALS AND METHODS: After informed written consent was obtained, 1520 individuals were enrolled. Protocol was approved by institutional review board and National Cancer Institute and was compliant with Health Insurance Portability and Accountability Act, or HIPAA. Participants were aged 50 years and older and had smoked for more than 20 pack-years...

OBJECTIVES: To evaluate the hypothesis that computed tomography (CT) angiography often yields a result interpreted as an alternative diagnosis to pulmonary embolism (PE) in emergency department (ED) patients. METHODS: This was a multicenter, retrospective, and secondary analysis of consecutive patients in three academic emergency departments. ED patients with symptoms suspicious for PE were included. CT angiography was ordered at the discretion of the treating physician; patients were identified...

Abstract Background Incidental findings (IFs) are common among injured patients and create a complex problem with no standardized solution. Materials and methods This is a retrospective review of adult trauma patients admitted to a level I trauma center from January to May 2017. IFs from abdominal, chest, and neck imaging were categorized based on previously published guidelines focused on clinically significant IFs. Patient demographics related to access to care were collected. Outcome measures...

Abstract Background As the focused assessment with sonography for trauma (FAST) examination becomes increasingly ubiquitous in the emergency department (ED), a parallel increase in incidental findings can also be expected. The purpose of this study was to determine the prevalence, documentation, and communication of incidental findings on emergency physician-performed FAST examinations. Methods Retrospective review at two academic EDs. Adult trauma patients undergoing FAST examinations used for ...

Abstract Background This study evaluates whether trauma patients who incidentally learned about a malignancy have similar long-term outcomes as patients who organically learned about their malignancy. Materials and methods Incidental findings (IF) patients were matched to noninjured cancer controls on age group, sex, cancer site, stage, and year of diagnosis. Unadjusted covariates included race, insurance type, rural residence, and time from diagnosis to first cancer intervention. Cox proportion...

Objectives Whole-body CT scans are commonly performed to assess trauma patients, and often reveal incidental findings (IFs) the patient may be unaware of. We assessed the prevalence, associations, and adequacy of follow-up of IFs.

Purpose Computed tomography scans of the abdomen/pelvis (CTAP) in the adult population may reveal findings unrelated to the injury, such as a mass; the occurrence of incidental findings in pediatric patients remains unknown. This study aims to determine the percentage of pediatric trauma patients with incidental findings.

Inappropriate use of diagnostic imaging in the emergency department setting is a growing concern. Multiple factors drive imaging utilization in the ED, and diagnostic imaging use has increased dramatically in the past two decades. Medical radiation now accounts for the largest percent of artificial exposure to ionizing radiation in the USA, and while a direct link between radiation exposure from imaging and cancer development has not been proven, there is increasing concern about the potential h...

There is an emerging consensus that genomic researchers should, at a minimum, offer to return to individual participants clinically valid, medically important and medically actionable genomic findings (for example, pathogenic variants in BRCA1) identified in the course of research. However, this is not a common practice in psychiatric genetics research. Furthermore, psychiatry researchers often generate findings that do not meet all of these criteria, yet there may be ethically compelling argume...

Abstract Background Incidental findings are prevalent in imaging but often go unreported to patients. Such unreported findings may present the potential for harm as well as medico-legal ramifications. Methods A chart review of trauma patients was undertaken over a year. Systems-based changes were made utilizing our electronic medical record system and our staff protocols to improve the disclosure of clinically relevant incidental findings to patients. Results During the preintervention period, 6...

Incidental cardiovascular findings are common and can be found in up to 70% of patients. Previously, several reports about incidental findings (IFs) on whole body computed tomography (CT) were published. However, no previous study investigated cardiovascular IFs in patients with unclear finding situation and trauma of unknown origin on whole body CT.The radiological database of 2 university hospitals was screened for patients with trauma of unknown origin and unclear finding situation investigat...
