Unplanned readmission after lung resection surgery: A systematic review.

Urgent readmissions have a major impact on outcomes in patient health and healthcare costs. The associated risk factors have generally been infrequently studied. The main objective of the present work is to identify pre- and perioperative determinants of readmission; the secondary aim was to determine readmission rate, identification of readmission diagnoses, and impact of readmissions on survival rates in related analytical studies. The review was performed through a systematic search in the main bibliographic databases. In the end, 19 papers met the selection criteria. The main risk factors were: sociodemographic patient variables; comorbidities; type of resection; postoperative complications; long stay. Despite the great variability in the published studies, all highlight the importance of reducing readmission rates because of the significant impact on patients and the healthcare system.
