J Gastrointest Surg 2017; 21:1304-1308.

Abstract
BACKGROUND Laparoscopic ileal pouch-anal anastomosis (L-IPAA) has been increasingly adopted over the last decade due to short-term patient-related benefits. Several studies have shown L-IPAA to be equivalent to open IPAA in terms of safety and short-term outcomes. However, few L-IPAA studies have examined long-term functional outcomes. We aimed to evaluate the long-term functional outcomes of L-IPAA as compared to open IPAA. METHODS A previous case-matched cohort study at our institution compared short-term outcomes between L-IPAA and open IPAA from 1998 to 2004. For this study, we selected all patients from this case-matched cohort study with chronic ulcerative colitis (CUC) who had follow-up functional data of greater than 1 year. Functional data was obtained through prospective surveys, which were sent annually to all IPAA patients postoperatively. RESULTS One hundred and forty-nine patients (58 L-IPAA, 91 open IPAA) with a median 8-year duration of follow-up were identified. There were no differences in demographics and long-term surgical outcomes between groups. Stapled anastomosis was more common in the laparoscopic group (91.4 versus 54.9%, p < 0.001). Stool frequency during daytime (>6 stools, L-IPAA 32.8%, open 49.4%, p = 0.048) and nighttime (>2 stools, L-IPAA 13.8%, open 30.6%; p = 0.024) was significantly lower in the L-IPAA group. Ability to differentiate gas from stool was not different (p = 0.13). Rate of complete continence was similar in L-IPAA and open groups (L-IPAA 36.2%, open 21.8%, p = 0.060). There was no difference in use of medication to control stools, perianal skin irritation, voiding difficulty, sexual problems, and occupational change between groups. Subgroup analysis to evaluate for any group differences attributable to anastomotic technique demonstrated only that stapled anastomoses lead to more perianal skin irritation in the L-IPAA group (L-IPAA = 60.4% versus open IPAA = 38.8%; p = 0.031). CONCLUSION Overall, L-IPAA has comparable functional results to the open approach with slightly lower daytime and nighttime stool frequency. This difference may be attributed to a greater number of stapled anastomoses performed in the laparoscopic cohort.

Abstract
BACKGROUND Colorectal surgical site infections (SSIs) contribute to postoperative morbidity, mortality, and resource utilization. Risk factors associated with colorectal SSI are well-documented. However, quality improvement efforts are informed by national data, which may not identify institution-specific risk factors. METHOD Retrospective cohort study of colorectal surgery patients uses institutional ACS-NSQIP data from 2006 through 2014. ACS-NSQIP data were enhanced with additional variables from medical records. Multivariable logistic regression identified factors associated with SSI development. RESULTS Of 2376 patients, 213 (9.0%) developed at least one SSI (superficial 4.8%, deep 1.1%, organ space 3.5%). Age < 40, BMI > 30, ASA3+, steroid use, smoking, diabetes, pre-operative sepsis, higher wound class, elevated WBC or serum glutamic-oxalocetic transaminase, low hematocrit or albumin, Crohn's disease, and prolonged incision-to-closure time were associated with increased SSI rate (all P < 0.01). After adjustment, BMI > 30, steroids, diabetes, and wound contamination were associated with SSI. Patients with Crohn's had greater odds of SSI than other indications. CONCLUSION Institutional modeling of SSI suggests that many previously suggested risk factors established on a national level do not contribute to SSIs at our institution. Identification of institution-specific predictors of SSI, rather than relying upon conclusions derived from external data, is a critical endeavor in facilitating quality improvement and maximizing value of quality investments.

Abstract
INTRODUCTION Returns to the operating room (ROR) have been suggested as a marker of surgical quality. Increasingly, quality and value metrics are utilized for reimbursement as well as public reporting to inform health care consumers. We sought to understand the etiology of ROR and assess the validity of simple ROR as a quality metric. METHODS This was a single referral center retrospective review of all colon and rectal operations between January 1, 2014 and December 31, 2014. Surgical Systems Nurse + was constructed and validated at our institution for classifying ROR as either an unplanned return to the OR, planned return due to complications, planned staged return, or an unrelated return. The primary outcome was the classification of ROR and total number of ROR within 30 days. RESULTS Of the 2389 colorectal patients who underwent surgery between January 1, 2014 and December 31, 2014; 214 returned to the operating room within 30 days (9.0%). Among the 214 patients, there were a total of 232 ROR with an average of 1.1 ROR per patient (range 1-4); 90 (38.8%) were unplanned ROR, 49 (21.1%) were planned returns due to complications, 92 (39.7%) were planned staged returns, and 1 (0.4%) were unrelated ROR. The most common reason for an unplanned ROR was an anastomotic leak (n = 21; 9.1%). Overall, unplanned reoperations were rare events (n = 90/2389; 3.8%), largely comprised of patients experiencing an anastomotic abscess or leak (n=21/2389; 0.9%). CONCLUSIONS In a high volume and complexity academic colon and rectal surgery practice, RORs within 30 days occurred after 10.4% of cases. Unplanned ROR were relatively rare and most commonly associated with an anastomotic leak. Since the majority of ROR were planned-staged returns, overall rate of ROR should be questioned as a metric of surgical quality. Perhaps, the anastomotic leak rate may be a better metric to monitor for quality improvement efforts.

Abstract
Objective To develop and validate a phenotyping algorithm for the identification of patients with type 1 and type 2 diabetes mellitus (DM) preoperatively using routinely available clinical data from electronic health records. Patients and Methods We used first-order logic rules (if-then-else rules) to imply the presence or absence of DM types 1 and 2. The “if” clause of each rule is a conjunction of logical and, or predicates that provides evidence toward or against the presence of DM. The rule includes International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes, outpatient prescription information, laboratory values, and positive annotation of DM in patients’ clinical notes. This study was conducted from March 2, 2015, through February 10, 2016. The performance of our rule-based approach and similar approaches proposed by other institutions was evaluated with a reference standard created by an expert reviewer and implemented for routine clinical care at an academic medical center. Results A total of 4208 surgical patients (mean age, 52 years; males, 48%) were analyzed to develop the phenotyping algorithm. Expert review identified 685 patients (16.28% of the full cohort) as having DM. Our proposed method identified 684 patients (16.25%) as having DM. The algorithm performed well—99.70% sensitivity, 99.97% specificity—and compared favorably with previous approaches. Conclusion Among patients undergoing surgery, determination of DM can be made with high accuracy using simple, computationally efficient rules. Knowledge of patients’ DM status before surgery may alter physicians’ care plan and reduce postsurgical complications. Nevertheless, future efforts are necessary to determine the effect of first-order logic rules on clinical processes and patient outcomes.

Abstract
INTRODUCTION Vedolizumab was recently approved by the Food and Drug Administration for the treatment of moderate to severe ulcerative colitis [UC] and Crohn's disease [CD]. No study to date has examined the rate of postoperative infectious complications among patients who received vedolizumab in the perioperative period. We sought to determine the 30-day postoperative infectious complication rate among inflammatory bowel disease [IBD] patients who received vedolizumab within 12 weeks of an abdominal operation as compared to patients who received tumour necrosis factor α [TNFα] inhibitors or no biological therapy. METHODS A retrospective chart review between May 1, 2014 and December 31, 2015 of adult IBD patients who underwent an abdominal operation was performed. The study cohort comprised patients who received vedolizumab within 12 weeks of their abdominal operation and the control cohorts were patients who received TNFα inhibitors or no biological therapy. RESULTS In total, 94 patients received vedolizumab within 12 weeks of an abdominal operation. Fifty experienced postoperative complications [53%], 35 of which were surgical site infections [SSIs] [36%]. The vedolizumab group experienced significantly higher rates of any postoperative infection [53% vs 33% anti-TNF and 28% non-biologics; p<0.001] and SSI [37% vs 10% and 13%; p<0.001]. On univariate and multivariate analysis, exposure to vedolizumab remained a significant predictor of postoperative SSI [p<0.001]. CONCLUSIONS Thirty-seven per cent of IBD patients who received vedolizumab within 30 days of a major abdominal operation experienced a 30-day postoperative SSI, significantly higher than patients receiving TNFα inhibitors or no biological therapy. Vedolizumab within 12 weeks of surgery remained the only predictor of 30-day postoperative SSI on multivariate analysis.

Abstract
PURPOSE The American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) is a clinically-derived, validated tool to track outcomes in surgery. The Agency for Healthcare Research and Quality Patient Safety Indicators (AHRQ-PSI) are a set of computer algorithms run on administrative data to identify adverse events. The purpose of this study is to compare complications following orthopedic surgery identified by ACS-NSQIP and AHRQ-PSI. METHODS Patients between 2010 and 2012 who underwent orthopedic procedures (arthroplasty, spine, trauma, foot and ankle, hand, and upper extremity) at our tertiary-care, academic institution were identified (n = 3,374). Identification of inpatient adverse events by AHRQ-PSI in the cohort was compared with 30-day events identified by ACS-NSQIP. Adverse events common to both AHRQ-PSI and ACS-NSQIP were infection, sepsis, venous thromboembolism, bleeding, respiratory failure, wound disruption, and renal failure. Concordance between AHRQ-PSI and ACS-NSQIP for identifying adverse events was examined. RESULTS A total of 729 adverse events (21.6%) were identified in the cohort using ACS-NSQIP methodology and 35 adverse events (1.0%) were found using AHRQ-PSI. Only 12 events were identified by both methodologies. The most common complication was bleeding in ACS-NSQIP (18.1%) and respiratory failure in AHRQ-PSI (0.53%). The overlap was highest for venous thromboembolic events. There was no overlap in adverse events for 5 of the 7 categories of adverse events. CONCLUSIONS A large discrepancy was observed between adverse events reported in ACS-NSQIP and AHRQ-PSI. A large percentage of clinically important adverse events identified in ACS-NSQIP were missed in AHRQ-PSI algorithms. The ability of AHRQ-PSI for detecting adverse events varied widely with ACS-NSQIP. CLINICAL RELEVANCE AHRQ-PSI algorithms currently are insufficient to assess the quality of orthopedic surgery.

Abstract
BACKGROUND Surgical site infections (SSI) contribute to surgical patients' morbidity and costs. Operating room traffic may be a modifiable risk factor for SSI. We investigated the impact of additional operating room personnel on the risk of superficial SSI (sSSI). PATIENTS AND METHODS In this matched case-control study, cases included patients in whom sSSI developed in clean surgical incisions after elective, daytime operations. Control subjects were matched by age, gender, and procedure. Operating room personnel were classified as (1) surgical scrubbed, (2) surgical non-scrubbed, or (3) anesthesia. We used conditional logistic regression to test the extent to which additional personnel overall and from each work group were associated with infection. RESULTS In total, 474 patients and 803 control subjects were identified. Each additional person among total personnel and personnel from each work group was significantly associated with greater odds of infection (all personnel, odds ratio [OR] = 1.082, 95% confidence interval [CI] 1.031-1.134, p = 0.0013; surgical scrubbed OR = 1.132, 95% CI 1.029-1.245, p = 0.0105; surgical non-scrubbed OR = 1.123, 95% CI 1.008-1.251, p = 0.0357; anesthesia OR = 1.153, 95% CI 1.031-1.290, p = 0.0127). After adjusting for operative duration, body mass index, diabetes mellitus, and vascular disease, additional personnel and sSSI were no longer associated overall or for any work groups (total personnel OR = 1.033, 95% CI 0.974-1.095, p = 0.2746; surgical scrubbed OR = 1.060, 95% CI 0.952-1.179, p = 0.2893; surgical non-scrubbed OR = 1.023 95% CI 0.907-1.154, p = 0.7129; anesthesia OR = 1.051, 95% CI 0.926-1.193, p = 0.4442). CONCLUSION The presence of additional operating room personnel was not independently associated with increased odds of sSSI. Efforts dedicated to sSSI reduction should focus on other modifiable risk factors.

Abstract
BACKGROUND The incidence of metachronous colorectal cancer (MCRC) among colorectal cancer (CRC) survivors varies significantly, and the optimal colonoscopy surveillance practice for mitigating MCRC incidence is unknown. METHODS A cost-effectiveness analysis was used to compare the performances of the US Multi-Society Task Force guideline and all clinically reasonable colonoscopy surveillance strategies for 50- to 79-year-old posttreatment CRC patients with a computer simulation model. RESULTS The US guideline [(1,3,5)] recommends the first colonoscopy 1 year after treatment, whereas the second and third colonoscopies are to be repeated at 3- and 5-year intervals. Some promising alternative cost-effective strategies were identified. In comparison with the US guideline, under various scenarios for a 20-year period, 1) reducing the surveillance interval of the guideline after the first colonoscopy by 1 year [(1,2,5)] would save up to 78 discounted life-years (LYs) and prevent 23 MCRCs per 1000 patients (incremental cost-effectiveness ratio [ICER] ≤ $23,270/LY), 2) reducing the intervals after the first and second negative colonoscopies by 1 year [(1,2,4)] would save/prevent up to 109 discounted LYs and 36 MCRCs (ICER ≤ $52,155/LY), and 3) reducing the surveillance intervals after the first and second negative colonoscopy by 1 and 2 years [(1,2,3)] would save/prevent up to 141 discounted LYs and 50 MCRCs (ICER ≤ $63,822/LY). These strategies would require up to 1100 additional colonoscopies per 1000 patients. Although the US guideline might not be cost-effective in comparison with a less intensive oncology guideline [(3,3,5); the ICER could be as high as $140,000/LY], the promising strategies would be cost-effective in comparison with such less intensive guidelines unless the cumulative MCRC incidence were very low. CONCLUSIONS The US guideline might be improved by a slight increase in the surveillance intensity at the expense of moderately increased cost. More research is warranted to explore the benefits/harms of such practices. Cancer 2016;122:2560-70. © 2016 American Cancer Society.

Abstract
PURPOSE A laparoscopic approach to proctocolectomy and ileal pouch-anal anastomosis (IPAA) in patients with chronic ulcerative colitis and familial adenomatous polyposis has grown in popularity secondary to reports of small series demonstrating short-term patient benefits. Limited data exist in large numbers of patients undergoing laparoscopic ileal pouch-anal anastomosis (L-IPAA). We aimed to analyze surgical outcomes in a large cohort of patients undergoing L-IPAA. METHODS From a prospectively maintained surgical database, 30-day surgical outcome data were reviewed for all L-IPAA performed for chronic ulcerative colitis and familial adenomatous polyposis from 1999 to 2012. Demographics, operative approach, and operative and postoperative complications were analyzed. RESULTS A total of 588 L-IPAA ileal pouch-anal anastomoses were performed predominantly for chronic ulcerative colitis (93.9 %). The mean age was 36.2 years, and 54.3 % were male, with a mean BMI of 24.1 kg/m(2). Three-stage operations were performed in 17.7 %. The mean operating time of the patients excluding 3-stage operation was 269.4 min. Minimally invasive techniques included hand-assist in 55 % and straight laparoscopy in 45 %. Conversion to open occurred in 8.8 %. Median length of stay was 5 days. There was no mortality. Complications occurred in 36.9 % of patients: Clavien grade I (17.5 %), grade II (72.8 %), and grade III (9.7 %). Analysis of the grouped data over time demonstrated a statistically significant reduction in operative time (p < 0.001) and an increase in the ratio of hand-assisted over straight laparoscopy (p = 0.001). CONCLUSIONS Minimally invasive IPAA performed using either a laparoscopic or hand-assisted technique is safe, can be performed with low conversion rates, and confers beneficial perioperative outcomes.

Abstract
Human jejunum smooth muscle cells (SMCs) and interstitial cells of Cajal (ICCs) express the SCN5A-encoded voltage-gated, mechanosensitive sodium channel NaV1.5. NaV1.5 contributes to small bowel excitability, and NaV1.5 inhibitor ranolazine produces constipation by an unknown mechanism. We aimed to determine the presence and molecular identity of Na(+) current in the human colon smooth muscle and to examine the effects of ranolazine on Na(+) current, mechanosensitivity, and smooth muscle contractility. Inward currents were recorded by whole cell voltage clamp from freshly dissociated human colon SMCs at rest and with shear stress. SCN5A mRNA and NaV1.5 protein were examined by RT-PCR and Western blots, respectively. Ascending human colon strip contractility was examined in a muscle bath preparation. SCN5A mRNA and NaV1.5 protein were identified in human colon circular muscle. Freshly dissociated human colon SMCs had Na(+) currents (-1.36 ± 0.36 pA/pF), shear stress increased Na(+) peaks by 17.8 ± 1.8% and accelerated the time to peak activation by 0.7 ± 0.3 ms. Ranolazine (50 μM) blocked peak Na(+) current by 43.2 ± 9.3% and inhibited shear sensitivity by 25.2 ± 3.2%. In human ascending colon strips, ranolazine decreased resting tension (31%), reduced the frequency of spontaneous events (68%), and decreased the response to smooth muscle electrical field stimulation (61%). In conclusion, SCN5A-encoded NaV1.5 is found in human colonic circular smooth muscle. Ranolazine blocks both peak amplitude and mechanosensitivity of Na(+) current in human colon SMCs and decreases contractility of human colon muscle strips. Our data provide a likely mechanistic explanation for constipation induced by ranolazine.

Abstract
BACKGROUND Systems that report hospital-based risk-adjusted surgical outcomes are potentially sensitive to the underlying methods used for risk adjustment. If a body of operations has a true level of risk that is higher than the estimated risk, then these operations might generate bias in the output of these reports. The objective of this study was to quantify the impact of unaccounted risk on the results of a surgical outcomes report. STUDY DESIGN We constructed a model simulating a universe of 500 hospitals, each providing care to 1,500 patients in a given year. The likelihood of morbidity and mortality for each of these patients was drawn from a random sampling of patients in the American College of Surgeons NSQIP. A single additional hospital was also simulated, within which a certain proportion (proportion varied from 2% to 10%) of patients had a significantly higher (odds ratio varied from 1 to 5) actual likelihood of mortality. RESULTS The presence of even a small proportion (2%) of patients with unaccounted risk had the potential to greatly increase the likelihood of a hospital being considered a statistical outlier (poor performer). This impact was greater in the assessment of complications than mortality. CONCLUSIONS This study shows that even a small proportion of patients with substantial levels of unaccounted risk can have a dramatic impact on the assessment of hospital-level risk-adjusted surgical outcomes. To avoid the unintended consequences associated with risk-averse behavior from providers, policy should be constructed to address this potential source of bias.

Abstract
INTRODUCTION We report the first prospective analysis of human factors elements contributing to invasive procedural never events by using a validated Human Factors Analysis and Classification System (HFACS). METHODS From August 2009 to August 2014, operative and invasive procedural "Never Events" (retained foreign object, wrong site/side procedure, wrong implant, wrong procedure) underwent systematic causation analysis promptly after the event. Contributing human factors were categorized using the 4 levels of error causation described by Reason and 161 HFACS subcategories (nano-codes). RESULTS During the study, approximately 1.5 million procedures were performed, during which 69 never events were identified. A total of 628 contributing human factors nano-codes were identified. Action-based errors (n = 260) and preconditions to actions (n = 296) accounted for the majority of the nano-codes across all 4 types of events, with individual cognitive factors contributing one half of the nano-codes. The most common action nano-codes were confirmation bias (n = 36) and failed to understand (n = 36). The most common precondition nano-codes were channeled attention on a single issue (n = 33) and inadequate communication (n = 30). CONCLUSION Targeting quality and interventions in system improvement addressing cognitive factors and team resource management as well as perceptual biases may decrease errors and further improve patient safety. These results delineate targets to further decrease never events from our health care system.

Abstract
BACKGROUND Our institutional policy allows patients who are scheduled for elective surgery with no history of a pregnancy or blood transfusion in the preceding 3 months to have a presurgical sample (PSS) collected and tested up to 56 days before their scheduled surgery; however, our PSS TS completion rate in eligible patients before the morning of surgery was 83%. In 2011, a team was charged to develop a standardized process along with other process improvements while ensuring no increase in transfusion-related events. STUDY DESIGN AND METHODS The team followed the DMAIC framework in appraising the effectiveness and efficiency of the current state process including baseline data collection such as PSS TS completion rate, number of eligible patients needing a PSS TS on the day of surgery, benchmarking, SSBO utilization, and future state mapping. RESULTS First quarter (Q1) 2011 versus Q1 2012 postimplementation results showed significant improvements of the process including a 53% decrease in PSS TS on the day of surgery; a 13% increase in PSS TS completion before the morning of surgery; a 26% reduction in total XM RBCs; and a 58.8% reduction in XM RBCs not issued, plus a 47% decrease in RBC wastage. Q1 2011 versus Q1 2013 showed a 41% reduction in total XM RBCs and an 88.4% reduction in XM RBCs not issued but overall RBCs issued versus returned increased slightly and represents a future opportunity for improvement. CONCLUSIONS The redesigned, transformational process eliminated SSBO and improved ordering process and PSS TS completion rate as well as blood product ordering and utilization.

Abstract
BACKGROUND/PURPOSE Identifying quality in pediatric surgery can be difficult given the low frequency of postoperative complications. We compared postoperative events following pediatric surgical procedures at a single institution identified by ACS-NSQIP Pediatric (ACS NSQIP-P) methodology and AHRQ Pediatric Quality Indicators (AHRQ PDIs), an administrative tool. METHODS AHRQ PDI algorithms were run on inpatient hospital discharge abstracts for 1257 children in the 2010 to 2013 ACS NSQIP-P at our institution. Four events-pulmonary complications, postoperative sepsis, wound dehiscence and bleeding-were matched between ACS NSQIP-P and AHRQ PDI. RESULTS Events were identified by ACS NSQIP-P in 7.9% of children and by AHRQ PDI in 8.0%. The four matched events were identified in 5.5% and 3.7%, respectively. Specificities of AHRQ PDI ranged from 97% to 100% and sensitivities from 0 to 2%. The largest discrepancy was in bleeding, where AHRQ PDI captured 1 of the 54 events identified by ACS NSQIP-P. None of the 41 pulmonary, sepsis, and wound dehiscence events identified by AHRQ PDI were clinically relevant according to ACS NSQIP-P. CONCLUSIONS Adverse events following pediatric surgery are infrequent; thus, additional measures of quality to supplement postoperative adverse events are needed. AHRQ PDIs are inadequate for assessing quality in pediatric surgery.

Abstract
BACKGROUND Anesthesiologists face increasing pressure to demonstrate the value of the care they provide, whether locally or nationally through public reporting and payor requirements. In this article, we describe the current state of performance measurement in anesthesia care at the national level and highlight gaps and opportunities in performance measurement for anesthesiologists. METHODS We evaluated all endorsed performance measures in the National Quality Forum (NQF), the clearinghouse for all federal performance measures, and classified all measures as follows: (1) anesthesia-specific; (2) surgery-specific; (3) jointly attributable; or (4) other. We used NQF-provided descriptors to characterize measures in terms of (1) structure, process, outcome, or efficiency; (2) patients, disease, and events targeted; (3) procedural specialty; (4) reporting eligibility; (5) measures stewards; and (6) timing in the care stream. RESULTS Of the 637 endorsed performance measures, few (6, 1.0%) were anesthesia-specific. An additional 39 measures (6.1%) were surgery-specific, and 67 others (10.5%) were jointly attributable. "Anesthesia-specific" measures addressed preoperative antibiotic timing (n = 4), normothermia (n = 1), and protocol use for the placement of central venous catheter (n = 1). Jointly attributable measures included outcome measures (n = 49/67, 73.1%), which were weighted toward mortality alone (n = 24) and cardiac surgery (n = 14). Other jointly attributable measures addressed orthopedic surgery (n = 4), general surgical oncologic resections (n = 12), or nonspecified surgeries (n = 15), but none specifically addressed anesthesia care outside the operating room such as for endoscopy. Only 4 measures were eligible for value-based purchasing. No named anesthesiology professional groups were among measure stewards, but surgical professional groups (n = 33/67, 47%) were frequent measure stewards. CONCLUSIONS Few NQF performance measures are specific to anesthesia practice, and none of these appears to demonstrate the value of anesthesia care or differentiate high-quality providers. To demonstrate their role in patient-centered, outcome-driven care, anesthesiologists may consider actively partnering in jointly attributable or team-based reporting. Future measures may incorporate surgical procedures not proportionally represented, as well as procedural and sedation care provided in nonoperating room settings.

Abstract
BACKGROUND Elective colectomy for diverticular disease is common. Some patients undergo primary resection with proximal diversion in an effort to limit morbidity associated with potential anastomotic leak. METHODS The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was queried. All patients undergoing a single, elective resection for diverticular disease from 2005 to 2011 were analyzed. Thirty-day outcomes were reviewed. Factors predictive of undergoing diversion and the risk-adjusted odds of postoperative morbidity with and without proximal diversion were determined by multivariable logistic regression models. RESULTS Fifteen thousand six hundred two patients undergoing non-emergent, elective resection were identified, of whom 348 (2.2 %) underwent proximal diversion. Variables predictive for undergoing proximal diversion included age ≥65 years, BMI ≥30, current smoking status, corticosteroid use, and serum albumin <3.0 g/dL. Multivariable analysis demonstrated that diversion was associated with significantly increased risk of surgical site infection (OR = 1.68), deep venous thrombosis (OR = 5.27), acute renal failure (OR = 5.83), sepsis or septic shock (OR = 1.75), readmission (OR = 2.57), and prolonged length of stay (OR = 3.35). CONCLUSIONS Proximal diversion in the setting of elective segmental colectomy for diverticular disease is uncommon. A combination of preoperative factors and intraoperative factors drives the decision for diversion. Patients who undergo diversion experience increased postoperative morbidity. Surgeons should have a low index of suspicion for postoperative complications and be prepared to mitigate their effect on the patient's outcome.
