Enhanced value with implementation of an ERAS protocol for ventral hernia repair.

BACKGROUND: Open ventral hernia repair (VHR) is associated with postoperative complications and hospital readmissions. A comprehensive Enhanced Recovery after Surgery (ERAS) protocol for VHR contributes to improved clinical outcomes including the rapid return of bowel function and reduced infections. The purpose of this study was to compare hospital costs for patients cared for prior to ERAS implementation with patients cared for with an ERAS protocol. METHODS: With IRB approval, clinical characteristics and postoperative outcomes data were obtained via retrospective review of consecutive VHR patients 2 years prior to and 14 months post ERAS implementation. Hospital cost data were obtained from the cost accounting system inclusive of index hospitalization. Clinical data and hospital costs were compared between groups. RESULTS: Data for 178 patients (127 pre-ERAS, 51 post-ERAS) were analyzed. Preoperative and operative characteristics including gender, ASA class, comorbidities, and BMI were similar between groups. ERAS patients had faster return of bowel function (p = 0.001) and decreased incidence of superficial surgical site infection (p = 0.003). Hospital length of stay did not vary significantly pre and post ERAS implementation. Inpatient pharmacy costs were increased in ERAS group ($2673 vs. $1176 p < 0.001), but total hospital costs (14,692 vs. 15,151, p = 0.538) were similar between groups. CONCLUSIONS: Standardization of hernia care via ERAS protocol improves clinical outcomes without impacting total costs.

Early outcomes of an enhanced recovery protocol for open repair of ventral hernia.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are evidence-based quality improvement pathways reported to be associated with improved patient outcomes. The purpose of this study was to compare short-term outcomes for open ventral hernia repair (VHR) before and after implementation of an ERAS protocol. METHODS: After obtaining IRB approval, surgical databases were searched for VHR cases for two years prior and eleven months after protocol implementation for retrospective review. Groups were compared on perioperative characteristics and clinical outcomes using chi-square, Fisher's exact, or Mann-Whitney U test, as appropriate. RESULTS: One hundred and seventy-one patients underwent VHR (46 patients with ERAS protocol in place and 125 historic controls). Age, gender, ASA Class, comorbidities, and smoking status were similar between the two groups. Body mass index was lower among ERAS patients (p = .038). ERAS patients had earlier return of bowel function (median 3 vs. 4 days) (p = .003) and decreased incidence of superficial surgical site infection (SSI) (7 vs. 25%) (p = .008) than controls. CONCLUSION: An ERAS protocol for VHR demonstrated improved patient outcomes. A system-wide culture focused on enhanced recovery is needed to ensure improved patient outcomes.

Left and right ventricular dyssynchrony and strains from cardiovascular magnetic resonance feature tracking do not predict deterioration of ventricular function in patients with repaired tetralogy of Fallot.

BACKGROUND: Patients with repaired tetralogy of Fallot (rTOF) suffer from progressive ventricular dysfunction decades after their surgical repair. We hypothesized that measures of ventricular strain and dyssynchrony would predict deterioration of ventricular function in patients with rTOF. METHODS: A database search identified all patients at a single institution with rTOF who underwent cardiovascular magnetic resonance (CMR) at least twice, >6 months apart, without intervening surgical or catheter procedures. Seven primary predictors were derived from the first CMR using a custom feature tracking algorithm: left (LV), right (RV) and inter-ventricular dyssynchrony, LV and RV peak global circumferential strains, and LV and RV peak global longitudinal strains. Three outcomes were defined, whose changes were assessed over time: RV end-diastolic volume, and RV and LV ejection fraction. Multivariate linear mixed models were fit to investigate relationships of outcomes to predictors and ten potential baseline confounders. RESULTS: One hundred fifty-three patients with rTOF (23 ± 14 years, 50 % male) were included. The mean follow-up duration between the first and last CMR was 2.9 ± 1.3 years. After adjustment for confounders, none of the 7 primary predictors were significantly associated with change over time in the 3 outcome variables. Only 1-17 % of the variability in the change over time in the outcome variables was explained by the baseline predictors and potential confounders. CONCLUSIONS: In patients with repaired tetralogy of Fallot, ventricular dyssynchrony and global strain derived from cine CMR were not significantly related to changes in ventricular size and function over time. The ability to predict deterioration in ventricular function in patients with rTOF using current methods is limited.
