      Abstract

      Objectives

      The need for routine chest radiography (CXR) 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 CXR in these patients.

      Methods

      Patients who underwent elective pulmonary resection, excluding pneumonectomy, for benign or malignant indications between 2007-2013 were reviewed. Patients with in-hospital mortality or without routine follow-up were excluded. During this interval, our practice transitioned from ordering routine CXRs post-chest tube removal and at first postoperative clinic visit to obtaining imaging based on symptomatology. The primary outcome was changes in management from results of CXRs obtained routinely versus for symptoms. Characteristics and outcomes were compared using Student’s t-test and chi-squared analyses.

      Results

      A total of 322 patients met inclusion criteria. Ninety-three underwent a routine same-day post-pull CXR and 229 did not. Thirty-three (14.4%) in the non-routine CXR cohort had imaging for symptoms, of which eight cases (24.2%) resulted in management changes. Only 3.2% of routine post-pull CXR resulted in management changes versus 3.5% of unplanned CXRs with no adverse outcomes (p=0.905). At outpatient postoperative follow-up, 146 patients received a routine CXR; none resulted in a change in management. Of the 176 that did not have a planned CXR at follow-up, 12 patients (6.8%) underwent a CXR for symptoms. Two of these patients required readmission and chest tube re-insertion.

      Conclusion

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