Routine chest radiography after thoracostomy tube removal and during postoperative follow-up is not necessary after...

The need for routine chest radiography following chest tube removal after elective pulmonary resection may be unnecessary in most patients. The purpose of this study was to determine the safety of eliminating routine chest radiography in these patients.

Patients who underwent elective pulmonary resection, excluding pneumonectomy, for benign or malignant indications between 2007 and 2013 were reviewed. Patients with in-hospital mortality or without routine follow-up were excluded. During this interval, our practice transitioned from ordering routine chest radiography after chest tube removal and at the first postoperative clinic visit to obtaining imaging based on symptomatology. The primary outcome was changes in management from results of chest radiography obtained routinely versus for symptoms. Characteristics and outcomes were compared using the Student t test and chi-square analyses.

A total of 322 patients met inclusion criteria. Ninety-three patients underwent a routine same-day post-pull chest radiography, and 229 patients did not. Thirty-three patients (14.4%) in the nonroutine chest radiography cohort received imaging for symptoms, in whom 8 (24.2%) resulted in management changes. Only 3.2% of routine post-pull chest radiography resulted in management changes versus 3.5% of unplanned chest radiography with no adverse outcomes (P = .905). At outpatient postoperative follow-up, 146 patients received routine chest radiography; none resulted in a change in management. Of the 176 patients who did not have planned chest radiography at follow-up, 12 (6.8%) underwent chest radiography for symptoms. Two of these patients required readmission and chest tube reinsertion.

Reserving imaging for patients with symptoms after chest tube removal and follow-up after elective lung resections resulted in a higher percentage of meaningful changes in clinical management.
