Background:
Routine chest x-rays (CXRs) ordered on thoracic surgery inpatients are common, costly, and of unclear clinical utility. We sought to investigate CXR ordering practices and their impact on clinical care.
Materials And Methods:
A single-center, retrospective cohort study of adult patients admitted after undergoing thoracic surgery with an intraoperative chest tube (CT) placed was performed over a 1-y period. Our primary outcome was a CXR-driven change in care. We evaluated routine CXR orders immediately after surgery in the postanesthesia care unit (PACU) and after final CT removal. "Routine" was defined as not ordered during a workup for a clinical concern. Patients were excluded if they underwent pleurodesis, were discharged with a CT, or had an immediate post-CT removal clinical change prompting intervention.
Results:
A total of 241 patients met inclusion. All patients received a routine PACU CXR, and 48% (117) had abnormal radiographic findings (e.g., pneumothorax, consolidation, effusion, etc). Secondary to this CXR, one patient (0.4%) experienced a change in care: a repeat CXR only. All patients received a routine final CT removal CXR, and 58% (140) had abnormal radiographic findings. After this CXR, 33 patients (14%) experienced a change in care: 32 underwent repeat CXR and one was clinically observed. Overall, no patients experienced a procedural intervention.
Conclusions:
Routine post-thoracic surgery CXRs in the PACU and after CT removal have limited clinical impact. Quality initiatives should be pursued to decrease empiric CXR use and reserve ordering for specific clinical concerns.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
