Operative management of non-elective incisional hernia reduces readmission in a national database

Purpose: The aim of this project was to compare patient characteristics, overall efficacy, and readmission events following operative vs non-operative management modalities of non-elective patients presenting with symptomatic incisional hernias. Methods: This study is a retrospective study of patients and patient demographics that presented as non-elective hospitalizations with symptomatic incisional hernia. Analysis of patients and characteristics utilized the National Readmission Database from 2010 to Q3 of 2015, delineating patient factors and outcomes following operative or non-operative management of hernias. Results: A total of 14,137 patients met inclusion criteria for our study. The majority of patients were treated operatively rather than non-operatively (79 vs. 21%) on their non-elective admission for incisional hernia. Those undergoing surgical management were younger (56 vs 61 years, p < 0.01), we more often of male gender (69 vs 64%, p < 0.01), and had fewer comorbidities (1.92 vs 2.97, p < 0.01) and chronic conditions (0.45 vs 2.68, p < 0.01). Patients managed operatively had a significantly lower readmission rate when compared to patients managed non-operatively (6.6 vs 14.3%, p < 0.01). However, non-operative management was associated with a shorter length of stay (3 vs 4 days, p < 0.01). Of patients who were initially medically managed and had to be readmitted, a further 61% underwent surgical treatment on their readmission. Conclusion: In this nationwide study, patients with non-elective admissions for incisional hernia were mostly managed surgically. Those managed operatively had lower rates of readmission when compared to non-operative management. Initial non-operative management was associated with a shorter length of stay and a lower cost to the patient. The results of this study support operative management of symptomatic incisional hernia.
