Rationale and Comments

Radiographic findings tend to lag behind clinical response. Obtaining routine follow-up chest radiograph in patients with CAP who have responded to prescribed therapy is therefore not indicated and does not improve care outcomes. This approach is similar to that outlined by the American Thoracic Society and Infectious Diseases Society of America, both of whom recommend not obtaining a follow-up chest radiograph in patients whose symptoms have resolved within five to seven days.
