Horseshoe Fistulae in the Age of LIFT.

BACKGROUND: Horseshoe fistula is a challenging benign anorectal condition to treat. The aim of this study was to assess the utilization and success of different definitive fistula repair techniques in the treatment of horseshoe fistula. METHODS: This was a retrospective case series which included all patients who were treated for horseshoe fistula from 2006 to 2019 at a single, tertiary care center and whom had at least one follow-up visit. Patients were excluded if < 18 years of age or carried a diagnosis of Crohn's disease. Patients were assessed for fistula recurrence and incontinence. RESULTS: Sixty-eight patients were identified. On average, they were 47 years old, 63% male, and 18% current smokers. Seventy-nine percent required seton during their treatment course. Of the 8 first attempts at fistula repair, the types of repair included flap (15%), LIFT (35%), fistulotomy (31%), plug (12%), and fistulotomy and immediate reconstruction (1%). Recurrence for these procedures was as follows: flap 30%, LIFT 21%, fistulotomy 14%, plug 88%, and fistulotomy and immediate reconstruction 0%. Twelve patients who recurred underwent 17 additional procedures to attempt to cure their fistula. Overall, of those who underwent any attempt at definitive repair, 82% of patients were cured of their fistula, 12% had a chronic seton, and 6% had a chronic fistula. Thirteen percent of those who were cured had incontinence. The mean follow-up time was 1.1 years. Patients required a median of 3 procedures (range 1-11). CONCLUSION: Horseshoe fistula remains a complex anorectal condition. Successful repair can be performed in > 80% of patients. However, repair can often require multiple surgical procedures.

What Can an Aging Pouch Tell Us? Outcomes of Ileoanal Pouches Over 20 Years Old.

BACKGROUND: Little is known about the long-term functional outcomes of restorative proctocolectomy. OBJECTIVE: The aim of this study was to examine ileoanal pouch outcomes 20 and 30 years postoperatively. DESIGN: This is a retrospective case series. SETTING: This study was conducted at a tertiary care referral center. PATIENTS: Patients who underwent restorative proctocolectomy between 1980 and 1994 were identified. Those with ≥20 years of in-person follow-up were included. MAIN OUTCOMES MEASURES: Pouch function, pouchitis, anal stricture, and pouch failure rates were analyzed. RESULTS: A total of 203 patients had ≥20 years of follow-up. Of those, 71 had ≥30 years of follow-up. Initial diagnoses included ulcerative colitis (83%), indeterminate colitis (9%), familial adenomatous polyposis (4%), and Crohn's disease (3%). Twenty-one percent of those with ulcerative or indeterminate colitis later transitioned to Crohn's disease. Mean daily stool frequency was 7 (IQR 6-8), 38% experienced seepage, 31% had anal stenosis, 47% experienced pouchitis, and 18% had pouch failure. Over time, stool frequency increased in 41% of patients, stayed the same in 43%, and decreased in 16%. Patients older than 50 years at the time of construction had more daily bowel movements (median 8 vs 6; p = 0.02) and more seepage (77% vs 35%; p = 0.005) than those younger than 50 years. Patients with Crohn's disease had higher stool frequency (median 8 vs 6; p < 0.001) and higher rates of anal stenosis (44% vs 26%; p = 0.02), pouchitis (70% vs 40%; p < 0.001), and pouch failure (38% vs 12%; p < 0.001) compared to non-Crohn's patients. Patients with ≥30 years of follow-up had similar function as those with 20-30 years of follow-up. LIMITATIONS: This was a retrospective, single-institution study. Only 35% of pouches created during the study period had >20 years of follow-up. CONCLUSIONS: Most patients maintain reasonably good function and retain their pouches after 20 years. Over time, stool frequency and seepage increase. Older age and Crohn's disease are associated with worse outcomes. See Video Abstract at http://links.lww.com/DCR/B801.

How to Get Ahead: Early-Career Colorectal Surgeons Reflect on Their First Few Years in Practice.

OBJECTIVE: To identify strategies and barriers to career progression in early-career colorectal surgeons. DESIGN: Qualitative research study performed via semi-structured interviews with early-career, board-certified colon, and rectal surgeons. Responses were analyzed, coded, and categorized to understand strategies towards career progression, perceived barriers to career progression, beliefs about case mix, and referral patterns. SETTING: Interviews conducted in person and via telephone across the United States and Canada. PARTICIPANTS: Early-career board-certified colorectal surgeons RESULTS: Twenty-two board-certified colorectal surgeons currently employed in 14 states and 1 foreign country were interviewed. Fourty-five percent were female. Their current practice environment was described as academic (77%), private practice (18%), or military (5%). Seventy-seven percent of surgeons were satisfied with their career progression. Seventy-two percent were satisfied with the case volume. Seventy-two percent were satisfied with their case mix. When asked about strategies for career progression, surgeons made 77 comments focused on three main themes: optimization of their job search, optimization of relationships while on the job, and efforts to augment individual achievement. When asked about barriers to career advancement, surgeons most frequently commented on a lack of time and a lack of mentors. When asked about case mix, 63% of surgeons felt that they had no control over it. They were evenly divided between believing that a broad case mix or a niche specialized case mix was more instrumental for career progression. CONCLUSIONS: Early-career colorectal surgeons were mostly satisfied with their career progression, volume, and case mix. In discussing their careers, many have developed a number of strategies focused on growth as an individual as well as relationship building. They also identified a number of barriers including lack of time and lack of mentorship. Early-career surgeons may be able to utilize these strategies and anticipate barriers prior to starting their first job, leading to greater likelihood of career satisfaction.

What influences conversion to open surgery during laparoscopic colorectal resection?

INTRODUCTION: We analyzed the risk of morbidity and mortality in laparoscopic (Lap) conversion for colorectal surgery across a group of subspecialist surgeons with expertise in minimally invasive techniques. METHODS: We reviewed prospective data patients who underwent abdominopelvic procedures from 7/1/2007 to 12/31/2016 at a tertiary care facility. We identified procedures that were converted from Lap to open (Lap converted). Lap converted procedures were matched to Lap completed and open procedures based on elective versus urgent and surgeon. We also abstracted patient demographics and outcomes at 30 days using the American College of Surgeons National Surgical Quality Improvement Program defined adverse event list. We analyzed outcomes across these groups (Lap converted, Lap completed, open procedures) with x2 and t tests and used the Bonferroni Correction to account for multiple statistical testing. RESULTS: From a database of 12,454 procedures, we identified 100 Lap converted procedures and matched them to 305 open procedures and 339 Lap completed procedures. In our dataset of abdominopelvic procedures, Lap techniques were attempted in 49 ± 1%. We noted a higher risk of aggerate morbidity following open procedures (33 ± 10) as compared to Lap converted (29 ± 17%) and the matched Lap completed procedures (18 ± 8%; p < 0.001). Converted cases had the longest operative time (222 ± 102 min), compared to lap completed (177 ± 110), and open procedures (183 ± 89). There were no differences in mortality, sepsis complications, anastomotic leaks, or unplanned returns to the operating room across the three operative groups. CONCLUSIONS: Although aggregate morbidity of Lap converted procedures is higher than in Lap completed procedures, it remains less than in matched open procedures. Compared to Lap completed procedures, the additional morbidity of Lap converted procedures appears to be related to additional surgical site infection risk. Our data suggest that surgeons should not necessarily be influenced by additional complications associated with conversion when contemplating complex laparoscopic colorectal procedures.

What Are the Cost Drivers for the Major Bowel Bundled Payment Care Improvement Initiative?

BACKGROUND: The Bundled Payments for Care Improvement initiative links payments for service beneficiaries during an episode of care (limited to 90 days from index surgery discharge). OBJECTIVE: The purpose of this study was to identify drivers of costs/payments for the major bowel Bundled Payments for Care Improvement initiative. DESIGN: Discharges from the Medicare Standard Analytic Files of hospitals participating in the major bowel bundle of the Bundled Payments for Care Improvement initiative were analyzed. SETTINGS: The study was conducted at 4 tertiary care centers. PATIENTS: All patients in diagnostic related groups of 329, 330, or 331 treated at eligible facilities between September 1, 2012, and September 30, 2014, were included. MAIN OUTCOME MEASURES: We calculated all costs/payments for the bundled period, that is, 3 days before surgery, the index hospitalization including surgery, and the 90-day postoperative period. We then determined costs for laparoscopic versus open procedures using International Classification of Diseases, Ninth Revision, procedure codes for each of the diagnostic related groups, as well as in aggregate. Last, we calculated differential impact of cost drivers on overall total episode costs. RESULTS: In the cohort of hospitals participating in the major bowel Bundled Payments for Care Improvement initiative, open procedures ($45,073) cost 1.6 times more than laparoscopic. For the lowest complexity diagnostic related group (331), performance of the procedure with open techniques was the largest total episode cost driver, because use of postdischarge services remained low. In the highest complexity diagnostic related group (329), readmission costs, skilled nursing facilities costs, and home health services costs were the greatest cost drivers after hospital services. LIMITATIONS: The analyses are limited by the retrospective nature of the study. CONCLUSIONS: These results indicate that efforts to safely perform open procedures with laparoscopic techniques would be most effective in reducing costs for lower complexity diagnostic related groups, whereas efforts to impact readmission and postdischarge service use would be most impactful for the higher complexity diagnostic related groups.

Luego, determinamos los costos de los procedimientos laparoscópicos versus abiertos utilizando códigos de procedimiento ICD-9 para cada uno de los GRD, así como en conjunto. Por último, calculamos el impacto diferencial de los generadores de costos sobre los costos totales del episodio.En la cohorte de hospitales que participan en la iniciativa BPCI del intestino principal, los procedimientos abiertos ($ 45.073) cuestan 1,6 veces más que los laparoscópicos. Para el GRD de menor complejidad (331), la realización del procedimiento con técnicas abiertas fue el mayor factor de costo total del episodio, ya que la utilización de los servicios posteriores al alta se mantuvo baja. En el GRD de mayor complejidad (329), los costos de readmisión, los costos de las instalaciones de enfermería especializada y los costos de los servicios de salud en el hogar fueron los mayores factores de costo después de los servicios hospitalarios.Los análisis están limitados por la naturaleza retrospectiva del estudio.Estos resultados indican que los esfuerzos para realizar procedimientos abiertos de manera segura con técnicas laparoscópicas serían más efectivos para reducir los costos de los GRD de menor complejidad, mientras que los esfuerzos para impactar la readmisión y la utilización del servicio posterior al alta serían más impactantes para los GRD de mayor complejidad.

What Is the Long-Term Follow-Up of Nonoperatively Treated Patients with Appendicitis?

In this study, we determine outcomes after nonoperative treatment of appendicitis. First, we abstracted data for patients discharged with a diagnosis of appendicitis from a tertiary care facility from August 1, 2007, through June 30, 2017. For patients treated nonoperatively, we collected additional medical treatment for appendicitis, future surgical treatment, and date of last follow-up. In our study, we identified 487 patients treated for appendicitis. From this group, 66 patients were successfully treated nonoperatively. Eight patients (12%) had an interval appendectomy at a mean follow-up time of two months. Of the 58 remaining patients, 20 (34%) did not have any further appendicitis-related issues over a mean follow-up period of 25 months. A total of 38 (66%) had recurring or additional concerns requiring further treatment or emergent surgery within a mean time of four months. A large proportion, 76 per cent (n = 29), required unscheduled or emergent appendectomy. There were more patients diagnosed with an abscess (55%) in the group that had further appendicitis issues. In conclusion, nonoperative treatment of appendicitis is associated with significant likelihood of future appendicitis-related treatment or emergency surgery (66%). In addition, patients diagnosed with an abscess are at particularly high risk of future appendicitis-related issues.

Should They Stay or Should They Go? The Utility of C-Reactive Protein in Predicting Readmission and Anastomotic Leak After Colorectal Resection.

BACKGROUND: Hospital readmission and anastomotic leak following colorectal resection have a negative impact on patients, surgeons, and the health care system. Novel markers of patients unlikely to experience these complications are of value in avoiding readmission. OBJECTIVE: This study aimed to determine the predictive value of C-reactive protein for readmission and anastomotic leak within 30 days following colorectal resection. DESIGN: This is a retrospective review of a prospectively compiled single-institution database. PATIENTS: From January 1, 2013, to July 20, 2017, consecutive patients undergoing elective colorectal resection with anastomosis without the presence of proximal intestinal stoma, who had C-reactive protein measured on postoperative day 3, were included. MAIN OUTCOME MEASURES: The primary outcome measured was the predictive value of C-reactive protein measured on postoperative day 3 for readmission or anastomotic leak within 30 days after colorectal resection. RESULTS: Of the 752 patients examined, 73 (10%) were readmitted within 30 days of surgery and 17 (2%) had an anastomotic leak. Mean C-reactive protein in patients who neither had an anastomotic leak nor were readmitted (127 ± 77 mg/L) was lower than for patients who were readmitted (157 ± 96 mg/L, p = 0.002) and lower than for patients who had an anastomotic leak (228 ± 123 mg/L, p = 0.0000002). The area under the receiver operating characteristic curve for the diagnostic accuracy of C-reactive protein for readmission was 0.59, with a cutoff value of 145 mg/L, generating a 93% negative predictive value. The area under the curve for the diagnostic accuracy of C-reactive protein for anastomotic leak was 0.76, with a cutoff value of 147 mg/L generating a 99% negative predictive value. LIMITATIONS: This study was limited by its retrospective design and because all patients were treated at a single center. CONCLUSIONS: Patients with a C-reactive protein below 145 mg/L on postoperative day 3 after colorectal resection have a low likelihood of readmission within 30 days, and a very low likelihood of anastomotic leak.

What do Young Colorectal Surgeons Value From Their CRS Residency Training?

OBJECTIVE: Colorectal surgery (CRS) training has seen many changes over the years. This study sought to identify aspects of CRS residency curriculum that were most valued by recent graduates and what changes could be made to improve training. DESIGN: Semistructured interviews were performed with board-certified colorectal surgeons 2 to 7years removed from their CRS residency. Interview responses were qualitatively analyzed and converted to coded, categorizable data. Subjects were recruited via a snowball sampling method. SETTING: Interviews were conducted in person and via telephone with surgeons in a variety of practices across the United States and Canada. Analysis was performed by a team at Lahey Clinic, Burlington, MA, an academic, tertiary care center. PARTICIPANTS: Board certified colorectal surgeons 2 to 7years removed from CRS residency. RESULTS: Twenty surgeons from 11 different CRS residencies were interviewed. At the time of the interview, surgeons were employed in 13 states and 1 foreign country. When asked what aspects of their CRS residency were of value, surgeons produced 74 comments emphasizing: volume of cases (65% of subjects), variety of cases (55%), development of technical skills (40%), management of specific diseases (35%), faculty (30%), mentorship (30%), and practice management (15%). With regard to technical skills, surgeons cited pelvic surgery (40%) and minimally invasive techniques (45%) as the exposures that helped them become successful. When discussing what could be added to training, subjects made 54 comments identifying: more robotic exposure (35%), more anorectal disease (30%), more pelvic floor exposure (25%), and practice management/billing (35%) as items to incorporate. Sixty five percent of subjects believed that "nothing" should be eliminated from their training. CONCLUSIONS: Young colon and rectal surgeons valued their training highly and strongly declined to eliminate any substantial part of the existing curriculum. They also expressed a strong desire to add more elements to the CRS residency including further robotic training, more anorectal, more pelvic floor, and further training in practice management.

What Is the Relationship between Operative Time and Adverse Events after Colon and Rectal Surgery?

We propose that prolonged colorectal surgery operative times are associated with increased 30-day adverse events. We identified a cohort from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from January 2005 through December 2012. Patients who underwent colectomy with primary anastomosis were selected using CPT codes. Operative time was categorized into short, average, and long based on mean operative times ±1 SD. NSQIP-approved multivariate models were used to identify associations between operative time and 30-day adverse events. A total of 113,615 patients underwent colorectal resection of which 46 per cent were laparoscopic and 12 per cent were identified as long operative times. Patients with long operative procedures had 34 per cent more superficial surgical site infections, 65 per cent more organ space infections, 69 per cent more abdominal dehiscences, 44 per cent more thrombotic complications, 45 per cent more urinary tract infections, 40 per cent more returns to the operating room, and 36 per cent more prolonged lengths of stay (P < 0.05 for all analyses). The multivariable analysis revealed an association between long operative times and increased adverse events despite adjustment for all NSQIP recommended covariates. Our results reveal increased 30-day adverse events with increased operative time. We propose that operative time may serve as a proxy for surgical complexity in colorectal surgery.

What factors are associated with increased risk for prolonged postoperative opioid usage after colorectal surgery?

BACKGROUND: Opioid-related deaths have increased substantially over the last 10 years placing clinician's prescription practices under intense scrutiny. Given the substantial risk of opioid dependency after colorectal surgery, we sought to analyze risk of postoperative prolonged opioid use after colorectal resections. METHODS: Between 2008 and 2014, patients undergoing abdominopelvic procedure with intestinal resection at a tertiary care facility were retrospectively identified. Patient's postoperative narcotic usage including their prescriptions on discharge and their total opioid medication use was recorded. Patient variables such as demographics, surgical characteristics, and prescription use were evaluated. Finally, we developed multivariate models to identify risk factors for prolonged opioid use (> 30 days after incident surgical procedure). RESULTS: We identified 9423 recorded procedures of which 2173 consisted of abdominopelvic procedures with intestinal resection and survived > 1 year. Of these, 91% (n = 1981) were discharged on opioids, and 98% (n = 1955) of those patients filled only one prescription. A total of 92 (4%) patients remained on opioids beyond 30 days, and from this group, 25% (n = 23 patients) remained at 90 days. We found no association between postoperative complications, stoma formation, and patient's sex with risk of prolonged opioid use. However, younger age and history of chronic pain were associated with an increased risk of prolonged opioid use. The use of minimally invasive techniques also attenuated the risk of prolonged opioid use (Table 2). CONCLUSION: A small but considerable proportion of patients remain on opioids beyond 30 days. Predictors of opioid use for greater than 30 days include a history of chronic pain and younger age. The use of minimally invasive techniques reduced the risk of prolonged opioid use. We identified several immutable risk factors that predicted prolonged postoperative opioid use; however, surgeons may be able to attenuate prolonged opioid use through the use of minimally invasive techniques.

Is Diversion with Ileostomy Non-inferior to Hartmann Resection for Left-sided Colorectal Anastomotic Leak?

BACKGROUND: Treatment of left-sided colorectal anastomotic leaks often requires fecal stream diversion for prevention of further septic complications. To manage anastomotic leak, it is unclear if diverting ileostomy provides similar outcomes to Hartmann resection with colostomy. METHODS: We identified all patients who developed anastomotic leak following left-sided colorectal resections from 1/2012 through 12/2014 using the American College of Surgeons National Surgical Quality Improvement Program. Then, we examined the risk of mortality and abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection. RESULTS: There were 1745 patients who experienced an anastomotic leak in a cohort of 63,748 patients (3.7%). Two hundred thirty-five patients had a reoperation for anastomotic leak involving the formation of a diverting ileostomy (n = 77) or Hartmann resection (n = 158). There was no difference in mortality or abdominal reoperation in patients treated with diverting ileostomy (3.9, 7.8%) versus Hartmann resection (3.8, 6.3%) (p = 0.8). CONCLUSION: There was no difference in the outcomes of mortality or need for second abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection for left-sided colorectal anastomotic leak. Thus, select patients with left-sided colorectal anastomotic leaks may be safely managed with diverting ileostomy.

Should classification as an ACS-NSQIP high outlier be used to direct hospital quality improvement efforts?

BACKGROUND: ACS-NSQIP classifies hospitals as "high outliers" if their performance is significantly worse than expected. We determined how often hospitals return to as-expected performance after being newly identified as outliers. METHODS: Outlier status was identified in ACS-NSQIP semi-annual reports (SARs) 2008-2011 for 13 postoperative adverse events. Pearson correlation and R2 measured the relationship between frequency of changes in outlier status, frequency of outlier identification, and adverse event rate. RESULTS: Among 284 hospitals, 75% were classified as high outliers for an adverse event at least once. New high outliers frequently did not remain outliers in the next SAR. Of new outliers, mortality had the highest percentage return to as-expected performance (62.7%), while surgical site infection had the lowest (20.5%). The likelihood of an outlier hospital returning to as-expected performance was inversely related to the percentage of hospitals classified as outliers. The percentage of hospitals classified as outliers for an event explained 60% of variation in outlier hospitals returning to as-expected performance. CONCLUSIONS: Outlier status may be less meaningful for adverse events with relatively few outlier hospitals.

What Is the Risk of Anastomotic Leak After Repeat Intestinal Resection in Patients With Crohn's Disease?

BACKGROUND: Approximately half of Crohn's patients require intestinal resection, and many need repeat resections. OBJECTIVE: The purpose of this study was to evaluate the increased risk of clinical anastomotic leak in patients with a history of previous intestinal resection undergoing repeat resection with anastomosis for Crohn's disease. DESIGN: This was a retrospective analysis of prospectively collected departmental data with 100% capture. SETTINGS: The study was conducted at the department of colorectal surgery in a tertiary care teaching hospital between July 2007 and March 2016. PATIENTS: A cohort of consecutive patients with Crohn's disease who were treated with intestinal resection and anastomosis, excluding patients with proximal fecal diversion, were included. The cohort was divided into 2 groups, those with no previous resection compared with those with previous resection. MAIN OUTCOME MEASURES: Clinical anastomotic leak within 30 days of surgery was measured. RESULTS: Of the 206 patients who met criteria, 83 patients had previous intestinal resection (40%). The 2 groups were similar in terms of patient factors, immune-suppressing medication use, and procedural factors. Overall, 20 clinical anastomotic leaks were identified (10% leak rate). There were 6 leaks (5%) detected in patients with no previous intestinal resection and 14 leaks (17%) detected in patients with a history of previous intestinal resection (p < 0.005). The OR of anastomotic leak in patients with Crohn's disease with previous resection compared with no previous resection was 3.5 (95% CI, 1.3-9.4). Patients with 1 previous resection (n = 53) had a leak rate of 13%, whereas patients with ≥2 previous resections (n = 30) had a leak rate of 23%. The number of previous resections correlated with increasing risk for clinical anastomotic leak (correlation coefficient = 0.998). LIMITATIONS: This was a retrospective study with limited data to perform a multivariate analysis. CONCLUSIONS: Repeat intestinal resection in patients with Crohn's disease is associated with an increased rate of anastomotic leakage when compared with initial resection despite similar patient, medication, and procedural factors.

The American Society of Colon and Rectal Surgeons Assessment Tool for Performance of Laparoscopic Colectomy.

BACKGROUND: The lack of consensus for performance assessment of laparoscopic colorectal resection is a major impediment to quality improvement. OBJECTIVE: The purpose of this study was to develop and assess the validity of an evaluation tool for laparoscopic colectomy that is feasible for wide implementation. DESIGN: During the pilot phase, a small group of experts modified previous assessment tools by watching videos for laparoscopic right colectomy with the following categories of experience: novice (less than 20 cases), intermediate (50-100 cases), and expert (more than 500 cases). After achieving sufficient reliability (κ > 0.8), a user-friendly tool was validated among a large group of blinded, trained experts. SETTING: The study was conducted through the American Society of Colon and Rectal Surgeons Operative Competency Evaluation Committee. PATIENTS: Raters were from the Operative Competency Evaluation Committee of the American Society of Colon and Rectal Surgeons. MAIN OUTCOME MEASURES: Assessment tool reliability and internal consistency were measured. RESULTS: From October 2014 through February 2015, 4 groups of 5 raters blinded to surgeon skill level evaluated 6 different laparoscopic right colectomy videos (novice = 2, intermediate = 2, expert = 2). The overall Cronbach α was 0.98 (>0.9 = excellent internal consistency). The intraclass correlation for the overall assessment was 0.93 (range, 0.77-0.93) and was >0.74 (excellent) for each step. The average scores (scale, 1-5) for experts were significantly better than those in the intermediate category, with a mean (SD) of 4.51 (0.56) versus 2.94 (0.56; p = 0.003). Videos in the intermediate group scored more favorably than beginner videos for each individual step and overall performance (mean (SD) = 3.00 (0.32) vs 1.78 (0.42); p = 0.006). LIMITATIONS: The study was limited by rater bias to technique and style. CONCLUSIONS: The unique and robust methodology in this trial produced an assessment tool that was feasible for raters to use when assessing videotaped laparoscopic right hemicolectomies. The potential applications for this new tool are widespread, including both training and evaluation of competence at the attending level.

Quality Improvement Initiatives in Colorectal Surgery: Value of Physician Feedback.

BACKGROUND: The impact of process improvement through surgeon feedback on outcomes is unclear. OBJECTIVE: We sought to evaluate the effect of biannual surgeon-specific feedback on outcomes and adherence to departmental and Surgical Care Improvement Project process measures on colorectal surgery outcomes. DESIGN: This was a retrospective analysis of prospectively collected 100% capture surgical quality improvement data. SETTING: This study was conducted at the department of colorectal surgery at a tertiary care teaching hospital from January 2008 through December 2013. MAIN OUTCOME MEASURES: Each surgeon was provided with biannual feedback on process adherence and surgeon-specific outcomes of urinary tract infection, deep vein thrombosis, surgical site infection, anastomotic leak, 30-day readmission, reoperation, and mortality. We recorded adherence to Surgical Care Improvement Project process measures and departmentally implemented measures (ie, anastomotic leak testing) as well as surgeon-specific outcomes. RESULTS: We abstracted 7975 operations. There was no difference in demographics, laparoscopy, or blood loss. Adherence to catheter removal increased from 73% to 100% (p < 0.0001), whereas urinary tract infection decreased 52% (p < 0.01). Adherence to thromboprophylaxis administration remained unchanged as did the deep vein thrombosis rate (p = not significant). Adherence to preoperative antibiotic administration increased from 72% to 100% (p < 0.0001), whereas surgical site infection did not change (7.6%-6.6%; p = 0.3). There were 2589 operative encounters with anastomoses. For right-sided anastomoses, the proportion of handsewn anastomoses declined from 19% to 1.5% (p < 0.001). For left-sided anastomoses, without diversion, anastomotic leak testing adherence increased from 88% to 95% (p < 0.01). Overall leak rate decreased from 5.2% to 2.9% (p < 0.05). LIMITATIONS: Concurrent process changes make isolation of the impact from individual process improvement changes challenging. CONCLUSIONS: Nearly complete adherence to process measures for deep vein thrombosis and surgical site infection did not lead to measureable outcomes improvement. Process measure adherence was associated with decreased rate of anastomotic leak and urinary tract infection. Biannual surgeon-specific feedback of outcomes was associated with improved process measure adherence and improvement in surgical quality.

Epidemiologic Analysis of Diverticulitis.

The aim of this article is to evaluate geographic variation in the incidence of diverticulitis and examine behavioral and environmental factors associated with high rates of diverticulitis across the United States. We used state hospital discharge data from 20 states to determine rates of inpatient diverticulitis from January 2002 to December 2004 at patient's county of residence. Next, we merged the county level data with behavioral and environmental survey data from the Behavioral Risk Factor Surveillance System (BRFSS). Finally, we determined the association between behavioral and environmental factors (i.e., teeth removal, dental cleaning, air quality, smoking, alcohol, vaccine, vitamins, and mental health) and high rates of diverticulitis. From January 1, 2002, to December 31, 2004, a total of 345,216 hospitalizations for acute diverticulitis were recorded for 1,055 counties. We identified rates of diverticulitis that ranged from 35.4 to 332.7 per 100,000 population. On univariate analysis, high diverticulitis burden was associated with regions of the country with substantial tooth loss from dental disease (45.8% for high diverticulitis counties vs. 37.5% for low diverticulitis counties; p = 0.0001). There is considerable variability in diverticulitis cases by county of residence across the nation. Potential triggers of diverticulitis may be associated with tooth removal and sun exposure.
