Comparative effectiveness of a mnemonic-use approach vs. self-study to interpret a lateral chest X-ray

The chest X-ray is the most commonly performed medical imaging study; however, the lateral chest film intimidates many physicians and medical students. The lateral view is more difficult to interpret than the frontal view but provides important information that is either not visible or not as evident on frontal view, and inability to read it may lead to missed diagnoses and more expensive imaging. The objective of this study was to assess a novel mnemonic-based approach to teaching medical students to proficiently read a lateral film using a prospective pilot study. A clinical faculty radiologist taught two groups of second-year medical students to read a lateral chest X-ray. One group learned a novel mnemonic-based method (MUM), and the other cohort performed directed web-based self-study (STMM). Each cohort was given a pre- and postassessment, and their performance was analyzed. A total of n = 29 students participated with n = 14 being taught the mnemonic method. The MUM group significantly ( P = 0.001) improved their score vs. the STMM group This study demonstrates students can quickly and effectively learn to read a lateral chest film using this novel mnemonic.

Abstract BACKGROUND: At the emergency department, there is a need for an instrument which is quick and easy to use to identify geriatric patients with the highest risk of mortality. The so- called ‘hanging chin sign’, meaning that the mandibula is seen to project over one or more ribs on the chest X-ray, could be such an instrument. This study aims to investigate whether the hanging chin sign is a predictor of mortality in geriatric patients admitted through the emergency department. METHODS: We performed an observational retrospective cohort study in a Dutch teaching hospital. Patients of ≥ 65 years who were admitted to the geriatric ward following an emergency department visit were included. The primary outcome of this study was mortality. Secondary outcomes included the length of admission, discharge destination and the reliability compared to patient-related variables and the APOP screener.RESULTS: 396 patients were included in the analysis. Mean follow up was 300 days; 207 patients (52%) died during follow up. The hanging chin sign was present in 85 patients (21%). Patients with the hanging chin sign have a significantly higher mortality risk during admission (OR 2.94 (1.61 to 5.39), p < 0.001), within 30 days (OR 2.49 (1.44 to 4.31), p = 0.001), within 90 days (OR 2.16 (1.31 to 3.56), p = 0.002) and within end of follow up (OR 2.87 (1.70 to 4.84),p < 0.001). A chest X-ray without a PA view or lateral view was also associated with mortality. This technical detail of the chest x-ray and the hanging chin sign both showed a stronger association with mortality than patient-related variables or the APOP screener. CONCLUSIONS: The hanging chin sign and other details of the chest x-ray were strong predictors of mortality in geriatric patients presenting at the emergency department. Compared to other known predictors, they seem to do even better in predicting mortality.

Preoperative Chest

To assess the value of routine preoperative chest x-ray films in pediatric patients, a prospective study of 1,500 patients, ages newborn to 19 years, was undertaken. Of all the patients, 7.5% demonstrated at least one roentgenographic abnormality, with 4.7% of the patients demonstrating a totally unsuspected significant roentgenographic anomaly. In 3.8% of the patients, surgery was either postponed or cancelled or the anesthetic technique was altered as a result of the roentgenographic finding. It is believed that the routine preoperative chest film is justified if the film is evaluated before surgery and the results clinically followed up.

A Caucasian woman aged 58 years with history of asthma and surgically repaired congenital diaphragmatic hernia presented to the emergency department (ED) with persistent cough, pleuritic chest pain, shortness of breath, in spite of recent treatment for influenza A virus. On physical examination, a large bulge was protruding from her left posterior thorax. She was found to have a large abnormal radiographic lucency on lateral chest X-ray posterior to the thoracic cavity, confirmed with chest CT to represent a large lung herniation in between the left seventh and eighth ribs. The patient was evaluated by a thoracic surgeon and offered surgical repair but ultimately decided on conservative management which to date has been ineffective.
