Background: Routine chest X-rays are the most widely obtained radiological studies during hospital admissions. In this study, we evaluated the utility of routine admission chest X-rays on patient care in patients admitted to The Brooklyn Hospital center.
Methods: We included consecutive patients admitted to the medical floors during a 4-month period who had a chest X-ray done on admission. The medical records of patients who had chest X-ray on admission were reviewed to identify any impact of chest X-ray on patient care during the course of hospitalization.
Results: Chest X-ray was noted to be done in 229 patients on admission. Chest X-rays of 100 (43.6%) patients were deemed medically necessary because of the presenting complaints which included cough (15.2%), fever (13.1%), dyspnea (6.1%), hemoptysis (1.7%), and combined symptoms (7.4%). Routine chest X-rays were done in 129 (56.3%) patients to rule out occult findings in the absence of any symptoms. Chest X-ray abnormalities were noted in 56 of 129 (43.4%) patients. In 51 of 56 patients, abnormalities were chronic, stable and previously known and did not contribute to patient care. In only 5 of 129 (3.87%) patients, there were findings which necessitated a change in patient care.
Conclusion: We conclude that routine chest films rarely reveal clinically unsuspected findings. The overall impact on patient care based on these findings is small when compared to the risks associated with repeated exposure to radiation. We recommend that routine chest X-ray films should not be ordered solely because of hospital admission.
