ABSTRACT
BACKGROUND: Surgeon instrument choices are influenced by training, previous experience, and established preferences. This causes variability in the cost of common operations, such as laparoscopic appendectomy. Many surgeons are unaware of the impact that this has on healthcare spending. OBJECTIVE: We sought to educate surgeons on their instrument use and develop standardized strategies for operating room cost reduction. DESIGN: We collected the individual surgeon instrument cost for performing a laparoscopic appendectomy. Sixteen surgeons were educated about these costs and provided with cost-effective instruments and techniques. SETTINGS: This study was conducted in a university-affiliated hospital system. PATIENTS: Patients included those undergoing a laparoscopic appendectomy within the hospital system. MAIN OUTCOME MEASURES: Patient demographics, operating room costs, and short-term outcomes for the fiscal year before and after the education program were then compared. RESULTS: During fiscal year 2013, a total of 336 laparoscopic appendectomies were performed compared with 357 in 2014. Twelve surgeons had a ≥5% reduction in average cost per case. Overall, the average cost per case was reduced by 17% (p < 0.001). Switching from an energy device to a stapler load or reusable plastic clip applier resulted in the largest savings per case at $321 or $442 per case. There were no differences in length of stay, 30-day readmissions, postoperative infections, operating time, or reoperations. LIMITATIONS: This retrospective study is subject to the accuracy of the medical chart system. In addition, specific instrument costs are based on our institution contracts and vary compared with other institutions. CONCLUSIONS: In this study we demonstrate that operative instrument costs for laparoscopic appendectomy can be significantly reduced by informing the surgeons of their operating room costs compared with their peers and providing a low-cost standardized instrument tray. Importantly, this can be realized without any incentive or punitive measures and does not negatively impact outcomes. Additional work is needed to expand these results to more operations, hospital systems, and training programs.

PURPOSE: We previously reported that analysis of histologically normal intestinal epithelium for spectral slope, a marker for aberrations in nanoscale tissue architecture, had outstanding accuracy in identifying field carcinogenesis in preclinical colorectal cancer models. In this study, we assessed the translatability of spectral slope analysis to human colorectal cancer screening. METHODS: Subjects (n = 127) undergoing colonoscopy had spectral slope determined from two endoscopically normal midtransverse colonic biopsies using four-dimensional elastic light-scattering fingerprinting and correlated with clinical findings. RESULTS: Four-dimensional elastic light-scattering fingerprinting analysis showed the submicron particles size progressively shifted toward larger sizes in subjects harboring neoplasia. There was a corresponding decrease in spectral slope values from the endoscopically normal mucosa in subjects harboring adenomas (n = 41) and advanced adenomas (n = 10), compared to neoplasia-free subjects (P = 0.00001). These factors did not appear to be confounded by either age or adenoma location. For detecting advanced adenomas, spectral slope had a negative and positive predictive value of 95 percent and 50 percent respectively. CONCLUSIONS: We demonstrate, for the first time, that spectral slope in "normal" mucosa can accurately risk-stratify patients for colonic neoplasia. This proof of concept study serves to underscore the promise of four-dimensional elastic light-scattering fingerprinting analysis for colorectal cancer screening.

BACKGROUND: Our aim was to determine the impact of surgeon education regarding disposable supply costs to reduce intraoperative costs for a common procedure such as inguinal hernia repair. STUDY DESIGN: At the end of the 2013 fiscal year (FY 13), surgeons in our department were provided with information about the cost of disposable equipment and implants used in common general surgery operations. Surgeons who historically had lower supply costs demonstrated individual techniques to their colleagues. No financial incentive or punitive measures were used to encourage behavior change. Surgical supply costs for laparoscopic and open inguinal hernia repair in FY13 were then compared with costs during fiscal year 2014 (FY14) using Mann-Whitney U tests. RESULTS: The average cost of laparoscopic inguinal hernia repairs decreased from an average $1,088±473 (±SD) in FY13 (n=258) to $860±441 (n=274) in FY14 after surgeon education, representing a 21.0% reduction in intraoperative costs (p<0.001). The most impactful adjustments to reduce costs included selective use of mesh fixation devices (22.9%) and balloon dissecting trocars (27.6%), reduction in use of disposable scissors (13.8%), and reduction in use of disposable clip appliers (3.7%). Open inguinal hernia costs were reduced from an average (±SD) of $315±$253 in FY13 (n=366) to $288±$130 in FY14 (n=286), an 8.6% reduction in cost (p<0.01). In these cases, both avoiding the use of fixation devices and using less expensive mesh implants were identified as significant factors. CONCLUSIONS: Surgeon education and empowerment may significantly reduce the cost of disposable equipment in laparoscopic and open inguinal hernia repair. This simple educational technique could prove financially beneficial throughout various procedures and disciplines.

BACKGROUND: Surgeons play a crucial role in the cost efficiency of the operating room through total operative time, use of supplies, and patient outcomes. This study aimed to examine the effect of surgeon education on disposable supply usage during laparoscopic cholecystectomy. METHODS: Surgeons were educated about the cost of disposable equipments without incentives for achieved cost reductions. Surgical supply costs for laparoscopic cholecystectomy in fiscal year (FY) 2013 were compared with FY 2014. RESULTS: The average disposable supply cost per laparoscopic cholecystectomy was reduced from $589 (n = 586) in FY 2013 to $531 (n = 428) in FY 2014, representing a 10% reduction in supply costs (P < .001). Adjustments included reduction in the use of expensive fascial closure devices, clip appliers, suction irrigators, and specimen retrieval bags. CONCLUSIONS: Disposable equipment cost for laparoscopic cholecystectomy can be reduced by surgeon education. These techniques can likely be used to reduce costs in an array of specialties and procedures.

Even under the most expert care, a properly constructed intestinal anastomosis can fail to heal, resulting in leakage of its contents, peritonitis, and sepsis. The cause of anastomotic leak remains unknown, and its incidence has not changed in decades. We demonstrate that the commensal bacterium Enterococcus faecalis contributes to the pathogenesis of anastomotic leak through its capacity to degrade collagen and to activate tissue matrix metalloproteinase 9 (MMP9) in host intestinal tissues. We demonstrate in rats that leaking anastomotic tissues were colonized by E. faecalis strains that showed an increased collagen-degrading activity and also an increased ability to activate host MMP9, both of which contributed to anastomotic leakage. We demonstrate that the E. faecalis genes gelE and sprE were required for E. faecalis-mediated MMP9 activation. Either elimination of E. faecalis strains through direct topical antibiotics applied to rat intestinal tissues or pharmacological suppression of intestinal MMP9 activation prevented anastomotic leak in rats. In contrast, the standard recommended intravenous antibiotics used in patients undergoing colorectal surgery did not eliminate E. faecalis at anastomotic tissues nor did they prevent leak in our rat model. Finally, we show in humans undergoing colon surgery and treated with the standard recommended intravenous antibiotics that their anastomotic tissues still contained E. faecalis and other bacterial strains with collagen-degrading/MMP9-activating activity. We suggest that intestinal microbes with the capacity to produce collagenases and to activate host metalloproteinase MMP9 may break down collagen in the intestinal tissue contributing to anastomotic leak.
