RESUMO
INTRODUCTION: Physicians have gravitated toward larger group practice arrangements in recent years. However, consolidation trends in colorectal surgery have yet to be well described. Our objective was to assess current trends in practice consolidation within colorectal surgery and evaluate underlying demographic trends including age, gender, and geography. METHODS: We performed a retrospective cross-sectional study using the Center for Medicare Services National Downloadable File from 2015 to 2022. Colorectal surgeons were categorized by practice size and by region, gender, and age. RESULTS: From 2015 to 2022, the number of colorectal surgeons in the United States increased from 1369 to 1621 (+18.4%), while the practices with which they were affiliated remained relatively stable (693-721, +4.0%). The proportion of colorectal surgeons in groups of 1-2 members fell from 18.9% to 10.7%. Conversely, those in groups of 500+ members grew from 26.5% to 45.2% (linear trend P < 0.001). The midwest region demonstrated the highest degree of consolidation. Affiliations with group practices of 500+ members saw large increases from both female and male surgeons (+148.9% and +86.9%, respectively). New surgeons joining the field since 2015 overwhelmingly practice in larger groups (5.3% in groups of 1-2, 50.1% in groups of 500+). CONCLUSIONS: Colorectal surgeons are shifting toward larger practice affiliations. Although this change is happening across all demographic groups, it appears unevenly distributed across geography, gender, and age. New surgeons are preferentially joining large group practices.

OBJECTIVES: We aimed to quantify the contributions of patient characteristics (PC), hospital structural characteristics (HC), and hospital operative volumes (HOV) to in-hospital mortality (IHM) after major surgery in the United States (US). BACKGROUND: The volume-outcome relationship correlates higher HOV with decreased IHM. However, IHM after major surgery is multifactorial, and the relative contribution of PC, HC, and HOV to IHM after major surgery is unknown. STUDY DESIGN: Patients undergoing major pancreatic, esophageal, lung, bladder, and rectal operations between 2006 and 2011 were identified from the Nationwide Inpatient Sample linked to the American Hospital Association survey. Multilevel logistic regression models were constructed using PC, HC, and HOV to calculate attributable variability in IHM for each. RESULTS: Eighty thousand nine hundred sixty-nine patients across 1025 hospitals were included. Postoperative IHM ranged from 0.9% for rectal to 3.9% for esophageal surgery. Patient characteristics contributed most of the variability in IHM for esophageal (63%), pancreatic (62.9%), rectal (41.2%), and lung (44.4%) operations. HOV explained < 25% of variability for pancreatic, esophageal, lung, and rectal surgery. HC accounted for 16.9% and 17.4% of the variability in IHM for esophageal and rectal surgery. Unexplained variability in IHM was high in the lung (44.3%), bladder (39.3%), and rectal (33.7%) surgery subgroups. CONCLUSIONS: Despite recent policy focus on the volume-outcome relationship, HOV was not the most important contributor to IHM for the major organ surgeries studied. PC remains the largest identifiable contributor to hospital mortality. Quality improvement initiatives should emphasize patient optimization and structural improvements, in addition to investigating the yet unexplained sources contributing to IHM.

BACKGROUND: Acute diverticulitis in immunocompromised patients is associated with high morbidity and mortality rates with either medical or surgical treatment. Thus, management approach is controversial, especially for patients presenting with nonperforated disease. OBJECTIVE: This study aimed to report the Mayo clinic experience of acute diverticulitis management in immunocompromised patients. DESIGN: This design is based on a retrospective cohort study. SETTING: This study was conducted with institutional data composed from 3 tertiary referral centers. PATIENTS: Immunocompromised patients presenting with acute diverticulitis at 3 Mayo clinic sites between 2016 and 2020 were included. MAIN OUTCOME MEASURES: The main outcome measures were the management algorithm and short-term outcomes. RESULTS: Immunocompromised patients presenting with acute uncomplicated diverticulitis (86) were all managed nonoperatively at presentation with a success rate of 93% (80/86). Two patients (2.3%, 2/86) required surgery during the same admission, and 4 patients (4.8%, 4/84) had 30-day readmission. Complicated diverticulitis patients with abscess (22) were all managed nonoperatively first with a success rate of 95.4% (21/22). One patient (4.6%, 1/22) required surgery during the same admission. All the patients who presented with obstruction (2), fistula (1), or free perforation (11) underwent surgery except one who chose hospice. Overall, the major complication rate was 50% (8/16) and mortality rate was 18.8% (3/16) among patients who underwent surgery during the same admission. For patients who presented with perforated diverticulitis, the mortality rate was 27.3% (3/11), compared with 0% (0/111) for patients who presented with nonperforated disease. LIMITATIONS: This cohort was limited by its retrospective nature and heterogeneity of the patient population. CONCLUSIONS: Nonoperative management was safe and feasible for immunocompromised patients with colonic diverticulitis without perforation at our center. Perforated colonic diverticulitis in immunocompromised patients was associated with high morbidity and mortality rate.

OBJECTIVE: To characterize agreement in the ascertainment of surgical site infections (SSIs) between the National Surgical Quality Improvement Program (NSQIP), National Healthcare Safety Network (NHSN), and administrative data. BACKGROUND: The NSQIP, NHSN, and administrative data are the primary systems used to monitor and report SSIs for the purpose of quality control and benchmarking of hospitals and surgeons. These systems have different methods for identifying SSIs. METHODS: We queried the NHSN, NSQIP, and administrative data systems for patients who had an operation at 1 of 4 hospitals within a single health system between January 2013 and September 2015. The detection of an SSI during a postoperative hospitalization was the outcome of analysis. Any SSI detected by one (or more) of these systems was analyzed by 2 reviewers to determine the presence of discrete elements of documentation constituting evidence of SSI. Concordance between the 3 systems (NHSN, NSQIP, and administrative data) was analyzed using Cohen's kappa. RESULTS: After application of appropriate exclusion criteria, a cohort of 9447 inpatient operations was analyzed. In total, 130 SSIs were detected by 1 or more of the 3 systems, with reported SSI rates of 0.5% (NHSN), 0.7% (administrative data), and 1.0% (NSQIP). Of these 130 SSIs, only 17 SSIs were reported by all 3 systems. The concordance between these 3 systems was moderate (kappa values NSQIP-NHSN = 0.50 [0.40-0.60], administrative-NHSN = 0.36 [0.24-0.47], and administrative-NSQIP = 0.47 [0.38-0.57]). Chart review found that reasons for discordance were related to issues of different criteria as well as inaccuracies. CONCLUSION: There is significant discordance in the determination of SSIs reported by the NHSN, NSQIP, and administrative data. The differences and limitations of each of these systems have to be recognized, especially when using these data for quality reports and pay for performance.

OBJECTIVE: To characterize agreement between administrative and registry data in the determination of patient-level comorbidities. BACKGROUND: Previous research finds poor agreement between these 2 types of data in the determination of outcomes. We hypothesized that concordance between administrative and registry data would also be poor. METHODS: A cohort of inpatient operations (length of stay 1 day or greater) was obtained from a consortium of 8 hospitals. Within each hospital, National Surgical Quality Improvement Program (NSQIP) data were merged with intra-institutional inpatient administrative data. Twelve different comorbidities (diabetes, hypertension, congestive heart failure, hemodialysis-dependence, cancer diagnosis, chronic obstructive pulmonary disease, ascites, sepsis, smoking, steroid, congestive heart failure, acute renal failure, and dyspnea) were analyzed in terms of agreement between administrative and NSQIP data. RESULTS: Forty-one thousand four hundred thirty-two inpatient surgical hospitalizations were analyzed in this study. Concordance (Cohen Kappa value) between the 2 data sources varied from 0.79 (diabetes) to 0.02 (dyspnea). Hospital variation in concordance (intersite variation) was quantified using a test of homogeneity. This test found significant intersite variation at a level of P < 0.001 for each of the comorbidities except for dialysis (P = 0.07) and acute renal failure (P = 0.19). These findings imply significant differences between hospitals in their generation of comorbidity data. CONCLUSION: This study finds significant differences in how administrative versus registry data assess patient-level comorbidity. These differences are of concern to patients, payers, and providers, each of which had a stake in the integrity of these data. Standardized definitions of comorbidity and periodic audits are necessary to ensure data accuracy and minimize bias.

BACKGROUND: To lessen the financial burden of total joint arthroplasty (TJA) and encourage shorter hospital stays, the Centers for Medicare and Medicaid Services (CMS) recently removed TKA from the inpatient-only list. This policy change now requires providers and institutions to apply the two-midnight rule (TMR) to short-stay (1-midnight) inpatient hospitalizations (SSIH). METHODS: The National Inpatient Sample from 2012 through 2016 was used to analyze trends in length of stay following elective TJA. Using publically-available policy documentation, published median Medicare payments, and National Inpatient Sample hospital costs, we analyzed the application of the TMR to SSIHs and compared the results to the previous policy environment. Specifically, we modeled 3 scenarios for all 2016 Medicare SSIHs: (1) all patients kept an extra midnight to satisfy the TMR, (2) all patients discharged as an outpatient, and (3) all patients discharged as an inpatient. RESULTS: The overall percentage of Medicare SSIHs increased significantly from 2.7% in 2012 to 17.8% in 2016 (P < .0001). Scenario 1 resulted in no change in out-of-pocket (OOP) costs to patients, no change in CMS payments, and hospital losses of $117.0 million. Scenario 2 resulted in no change in patient OOP costs, reduction in payments from CMS of $181.8 million, and hospital losses of $357.3 million. Scenario 3 resulted in no change in patient OOP costs, no change in CMS payments, and an estimated $1.71 billion of SSIH charges at risk to hospitals for audit. CONCLUSION: The results of this analysis reveal the conflict between length of stay trends following TJA and the imposition of the TMR.

BACKGROUND: Osteoarthritis (OA) is the leading cause of disability among adults in the United States. As the diagnosis is based on the accurate interpretation of knee radiographs, use of a convolutional neural network (CNN) to grade OA severity has the potential to significantly reduce variability. METHODS: Knee radiographs from consecutive patients presenting to a large academic arthroplasty practice were obtained retrospectively. These images were rated by 4 fellowship-trained knee arthroplasty surgeons using the International Knee Documentation Committee (IKDC) scoring system. The intraclass correlation coefficient (ICC) for surgeons alone and surgeons with a CNN that was trained using 4755 separate images were compared. RESULTS: Two hundred eighty-eight posteroanterior flexion knee radiographs (576 knees) were reviewed; 131 knees were removed due to poor quality or prior TKA. Each remaining knee was rated by 4 blinded surgeons for a total of 1780 human knee ratings. The ICC among the 4 surgeons for all possible IKDC grades was 0.703 (95% confidence interval [CI] 0.667-0.737). The ICC for the 4 surgeons and the trained CNN was 0.685 (95% CI 0.65-0.719). For IKDC D vs any other rating, the ICC of the 4 surgeons was 0.713 (95% CI 0.678-0.746), and the ICC of 4 surgeons and CNN was 0.697 (95% CI 0.663-0.73). CONCLUSIONS: A CNN can identify and classify knee OA as accurately as a fellowship-trained arthroplasty surgeon. This technology has the potential to reduce variability in the diagnosis and treatment of knee OA.

BACKGROUND: Currently, the largest available series of hip disarticulation (HD) procedures performed for periprosthetic joint infection (PJI) includes only 6 patients. Given the lack of data on this dreadful outcome, we sought to determine the frequency of and risk factors for HD performed for a primary diagnosis of PJI. METHODS: The National Inpatient Sample from 1998 to 2016 was used to estimate the annual incidences of HD associated with PJI, elective primary total joint arthroplasty (control group 1), and other surgical procedures associated with PJI (control group 2) using National Inpatient Sample trend weights. RESULTS: One-hundred forty-eight HDs for PJI, 2,378,313 primary total joint arthroplasty controls, and 51,580 PJI controls were identified. Median length-of-stay (11 days), proportion of patients with ≥5 comorbidities (22.8%), and median hospital costs ($25,895.60) were all greater for patients with HD compared with both control groups. The weighted frequency of HD hospitalizations increased by 366%, whereas the frequency of cases in control groups 1 and 2 increased by 93% and 310%, respectively, during the same timeframe. Upon multivariable logistic regression, age <65 years without private insurance (reference group: age ≥65 years without private insurance, odds ratio [OR]: 1.55; 95% confidence interval [CI]: 1.08-2.24), diabetes with chronic complications (OR: 1.91; 95% CI: 1.12-3.26), and peripheral vascular disease (OR: 2.59; 95% CI: 1.49-4.48) were significantly associated with increased risk of HD among all patients with PJI. CONCLUSION: While the overall frequency of lower extremity amputations may be decreasing, our study documents an alarming increase in the frequency of HD for PJI during the study period. Patients under age 65 years without private insurance were at significantly higher risk of HD among patients with PJI.

BACKGROUND: Regionalization of complex visceral surgery across the United States has followed identification of a volume-outcome association. However, improvements in postoperative mortality overall during the last decade may have weakened the strength of this association. METHODS: The National Cancer Database was used to identify patients undergoing colon, esophageal, liver, and pancreatic surgery from 2003 to 2011. Hospitals were divided into low-volume (< 33rd %tile), medium-volume (34-66th %tile), and high-volume (> 67th %tile) groups. Annual cancer-specific adjusted observed versus expected (O/E) ratios for 30- and 90-day mortality for each volume strata were calculated and plotted over time. RESULTS: In the year 2003, the O/E ratios decreased from low- to medium- to high-volume hospitals for all cancer surgeries for both 30- and 90-day mortality, indicating a strong volume-outcome relationship. For all volume strata, the O/E ratios trended downward from 2003 to 2011 for both 30- and 90-day mortality for all cancer surgeries. This trend was more pronounced for low- and medium-volume than for high-volume hospitals. Consequently, by 2011 the confidence intervals of the O/E ratios for the low-volume groups, and particularly for the medium-volume groups, overlapped those for the high-volume groups for most of the cancer surgeries studied. CONCLUSIONS: The volume-outcome association for major cancer surgery is dynamic and has attenuated over time primarily due to improvements in postoperative mortality at low- and medium-volume hospitals.

BACKGROUND: Kidney transplant (KT) patients presenting with cardiovascular (CVD) events are being managed increasingly in non-transplant facilities. We aimed to identify drivers of mortality and costs, including transplant hospital status. METHODS: Data from the 2009-2011 Nationwide Inpatient Sample, the American Hospital Association, and Hospital Compare were used to evaluate post-KT patients hospitalized for MI, CHF, stroke, cardiac arrest, dysrhythmia, and malignant hypertension. We used generalized estimating equations to identify clinical, structural, and process factors associated with risk-adjusted mortality and high cost hospitalization (HCH). RESULTS: Data on 7803 admissions were abstracted from 275 hospitals. Transplant hospitals had lower crude mortality (3.0% vs. 3.8%, p = 0.06), and higher un-adjusted total episodic costs (Median $33,271 vs. $28,022, p < 0.0001). After risk-adjusting for clinical, structural, and process factors, mortality predictors included: age, CVD burden, CV destination hospital, diagnostic cardiac catheterization without intervention (all, p < 0.001). Female sex, race, documented co-morbidities, and hospital teaching status were protective (all, p < 0.05). Transplant and non-transplant hospitals had similar risk-adjusted mortality. HCH was associated with: age, CVD burden, CV procedures, and staffing patterns. Hospitalizations at transplant facilities had 37% lower risk-adjusted odds of HCH. Cardiovascular process measures were not associated with adverse outcomes. CONCLUSION: KT patients presenting with CVD events had similar risk-adjusted mortality at transplant and non-transplant hospitals, but high cost care was less likely in transplant hospitals. Transplant hospitals may provide better value in cardiovascular care for transplant patients. These data have significant implications for patients, transplant and non-transplant providers, and payers.

INTRODUCTION: Mitomycin-C (MMC) and thiotepa are intravesical agents effective in reducing the recurrence of low-grade noninvasive bladder cancer when instilled perioperatively. No studies have compared these agents as a single-dose perioperative instillation. This study tests whether there is a difference in recurrence-free survival in patients with low-grade noninvasive bladder cancer who received intravesical MMC versus thiotepa. MATERIALS AND METHODS: A retrospective review was performed of patients who underwent cystoscopic excision of a bladder mass identified as a small, low-grade, treatment-naïve, noninvasive, wild-type urothelial carcinoma of the bladder and who received either intravesical thiotepa (30 mg/15 cc) or MMC (40 mg/20 cc) between January 1, 2002, and January 1, 2016. Data were collected for demographic characteristics, comorbid conditions, operative information, surveillance, and recurrence. The primary outcome was disease-free survival. Cohorts were compared via the doubly robust estimation approach, which used logistic regression to model the probability of recurrence. RESULTS: Of 154 total patients, 84 received intravesical MMC; 70, thiotepa. No statistical differences were shown between groups for age, sex, race, body mass index, smoking status, or baseline comorbid conditions; mass size, tumor multifocality, or tumor grade; and unadjusted recurrence rates (MMC, 36.0%; thiotepa, 46.0%; p = .33) at similar median follow up (MMC, 20.4; thiotepa, 22.8 months; p = .46). The robust logistic regression analysis yielded no differences in recurrence rates between MMC and thiotepa (OR, 0.65 [95% CI, 0.33-1.31]; p = .23). No episodes of myelosuppression or frozen pelvis were identified. CONCLUSIONS: As single-dose perioperative agents, both thiotepa and MMC were associated with similar recurrence-free survival rates.

BACKGROUND: Despite efforts to curtail the economic burden of total joint arthroplasty (TJA), utilization of these successful procedures continues to increase. Previous studies have provided evidence for pent-up demand (delaying necessary medical care until financially feasible) in health care as insurance status changes. We sought to determine whether evidence exists for pent-up demand in the TJA population when patients become eligible for Medicare enrollment. METHODS: The 2014 Nationwide Readmission Database was used to determine the incidence of TJA. The observed increase in incidence from age 64 to 65 was compared to the expected increase. Pent-up demand was calculated by subtracting the expected from the observed difference in frequency of TJA, and excess cost was determined by multiplying this value by the median cost of a primary TJA. The Medicare Expenditure Panel Survey Household Component was used to compare out-of-pocket (OOP) costs, access to care, and insurance coverage among patients aged 60-64 (group 1) and 66-70 (group 2). RESULTS: The expected and observed increases in TJA procedures from age 64 to 65 were 595 and 5211, respectively, resulting in pent-up demand of 4616 joint arthroplasties (1273 THA and 3343 TKA), and an excess cost of $55 million (range, $33 million-$70 million). Mean total OOP expenses for patients in group 1 were significantly greater ($1578.39) than patients in group 2 ($1143.63, P < .001). Despite spending more money OOP, the proportion of patients who were unable to obtain necessary medical care was significantly higher in group 1 than group 2 (4.9% vs 2.4%, P < .0001). This discrepancy was most prominent among patients with public insurance (10.6% vs 2.5%, P < .0001). CONCLUSION: The findings of this study suggest that patients with hip and knee osteoarthritis likely delay elective TJA until they are eligible for Medicare enrollment, resulting in significant additional financial burden to the public health system. As the population ages, it will become increasingly important for stakeholders and policy-makers to be aware of this pent-up demand for TJA procedures. LEVEL OF EVIDENCE: Therapeutic level IV.

Rarely, in fulminant Clostridium difficile infection (CDI), the rectal stump is persistently infected following total abdominal colectomy. We report cure of a septic patient with proctitis by fecal microbiota transplant via rectal swabs (mini-FMT). This novel procedure offers a management option for recurrent CDI following total abdominal colectomy.

OBJECTIVE: To characterize reasons for discordance between administrative data and registry data in the determination of postoperative infectious complications. BACKGROUND: Data regarding the occurrence of postoperative surgical complications are identified through either administrative or registry data. Rates of complications vary significantly between these two types of data; the reasons for this are not well-understood. METHODS: The occurrence of 30-day inpatient infectious complications (pneumonia, sepsis, surgical site infection, and urinary tract infection) was compared between the NSQIP and administrative mechanisms at 4 academic hospitals between 2012 and 2014. In each situation where the NSQIP and administrative data were discordant regarding the occurrence of a specific complication, a 2-clinician chart abstraction was performed to characterize the reasons for discordance as (i) administrative coding error, (ii) NSQIP coding error, (iii) "question of criteria", where the discordance was the result of differences in criteria, or (iv) "dually incorrect", where both data sources coded the complication incorrectly. RESULTS: The cohort included 19,163 patients undergoing surgery in 4 different academic hospitals. Rates of infectious complications varied up to 5-fold between the two data sources. A total of 717 discordant complications were identified. Of these, the greatest portion (43%) was due to "question of criteria," followed by administrative coding error (37%), NSQIP error (15%), and dually incorrect (5%). CONCLUSIONS: With a goal of improving existing mechanisms for measuring surgical quality, definitions for the occurrence of a postoperative complication need to be developed and applied consistently. Progress toward this goal will enable patients and payers to better take advantage of recent advances in healthcare data transparency.

BACKGROUND: Although major cancer surgery at a high-volume hospital is associated with lower postoperative mortality, the use of such hospitals may not be equally distributed. OBJECTIVE: Our aim was to study socioeconomic and racial differences in cancer surgery at Commission on Cancer (CoC)-accredited high-volume hospitals. METHODS: The National Cancer Database (NCDB) was used to identify patients undergoing surgery for colon, esophageal, liver, and pancreatic cancer from 2003 to 2012. Annual hospital volume for each cancer was categorized using quartiles of patient volume. Patient-level predictors of surgery at a high-volume hospital, trends in the use of a high-volume hospital, and adjusted likelihood of surgery at a high-volume hospital in 2012 versus 2003 were analyzed. RESULTS: African American patients were less likely to undergo surgery at a high-volume hospital for esophageal (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.49-0.73) and pancreatic cancer (OR 0.83, 95% CI 0.74-0.92), while uninsured patients and those residing in low educational attainment zip codes were less likely to undergo surgery at a high-volume hospital for esophageal, liver, and pancreatic cancer. In 2012, African Americans, uninsured patients, and those from low educational attainment zip codes were no more likely to undergo surgery at a high-volume hospital than in 2003 for any cancer type. These differences were not seen in colon cancer patients, for whom significant regionalization was not seen. CONCLUSIONS: Differences in the use of CoC-accredited high-volume hospitals for major cancer surgery were seen nationwide and persisted over the duration of the study. Strategies to increase referrals and/or access to high-volume hospitals for African American and socioeconomically disadvantaged patients should be explored.

BACKGROUND: The influence of distance traveled for treatment on short- and long-term cancer outcomes is unclear. METHODS: Patients with colon, esophageal, liver, and pancreas cancer from 2003 to 2006 were identified from the National Cancer Data Base (NCDB). Distance traveled for surgical treatment was estimated using zip code centroids. Propensity scores were generated for probability of traveling farther for treatment. Mixed effects logistic regression for 90-day mortality and Cox regression for 5-year mortality were compared between patients treated regionally and those traveling from farther away. RESULTS: The mean distance traveled for all patients for surgical resection was 30.0 ± 227 miles, with a median distance of 7.5 (interquartile range 14.4) miles. Patients who were aged ≥80 years, on Medicaid, or African American were less likely to be in the fourth quartile of distance (Q4) traveled for surgery. Patients who were in Q4 had a lower risk-adjusted 90-day mortality compared to Q1 for colon [odds ratio (OR) 0.89, 95 % confidence interval (CI) 0.82-0.96], liver (OR 0.49, 95 % CI 0.3-0.78), and pancreatic (OR 0.74, 95 % CI 0.56-0.98) cancer. Similarly, patients in Q4 for all tumor types had a lower risk-adjusted 5-year mortality compared to patients in Q1; colon (hazard ratio (HR) 0.96, 95 % CI 0.93-0.99), esophagus (HR 0.84, 95 % CI 0.75-0.94), liver (HR 0.75, 95 % CI 0.62-0.89), and pancreas (HR 0.87, 95 % CI 0.80-0.95). CONCLUSIONS: Greater travel distance for surgical resection of gastrointestinal cancers is associated with lower 90-day and 5-year mortality outcomes. This distance bias has implications for regionalization and reporting of cancer outcomes.

BACKGROUND: We hypothesized that after controlling for case-mix differences, the rates of positive resection margin after rectal cancer surgery vary substantially in the United States and that high-volume hospitals have lower margin positivity rates. MATERIALS AND METHODS: Patients treated with oncologic resection for stage I-III rectal cancer were selected from the 1998-2010 National Cancer Data Base. Hierarchical regression models were used to calculate risk- and reliability-adjusted positive margin rates and hospital level variability in positive margin rates using Empirical Bayes techniques. RESULTS: A total of 113,113 patients were treated at 1446 hospitals. The mean overall risk- and reliability-adjusted positive margin rate was 7.3%. High-volume hospitals did not have a lower rate of adjusted margin positivity (7.4%, P = 0.75). When both case mix and hospital volume differences were factored into the model, variability in margin positivity rates increased by 9.8%, implying that referral to high-volume hospitals alone would not improve margin positivity rates. CONCLUSIONS: Rectal cancer margin positivity rates vary substantially in the United States, despite adjusting for differences in case mix. These results support standardization of surgical technique and pathologic assessment as part of a broader initiative that identifies and refers patients to higher performing hospitals rather than simply to higher volume hospitals.

BACKGROUND: Routine cross-sectional imaging for staging of early-stage cutaneous melanoma is not recommended. This study sought to investigate the use of imaging for staging of cutaneous melanoma in the United States. METHODS: Patients with nonmetastatic cutaneous melanoma newly diagnosed between 2000 and 2007 were identified from the Surveillance Epidemiology End Results-Medicare registry. Any imaging study performed within 90 days after diagnosis was considered a staging study. RESULTS: The study identified 25,643 patients, 3,116 (12.2 %) of whom underwent cross-sectional imaging: positron emission tomography (PET) (7.2 %), computed tomography (CT) (5.9 %), and magnetic resonance imaging (MRI) (0.6 %). From 2000 to 2007, the use of cross-sectional imaging increased from 8.7 to 16.1 % (p < 0.001), driven predominantly by increased usage of PET (4.2-12.1 %). Stratification by T and N classification showed that cross-sectional imaging was used for 8.6 % of T1, 14.3 % of T2, 18.6 % of T3, and 26.7 % of T4 tumors (p < 0.001) and for 33.3 % of node-positive patients versus 11.1 % of node-negative patients (p < 0.001). Factors predictive of cross-sectional imaging included T classification [odds ratio (OR) for T4 vs T1, 2.66; 95 % confidence interval (CI) 2.33-3.03], node positivity (OR 2.70; 95 % CI 2.36-3.10), more recent year of diagnosis (OR 2.05 for 2007 vs 2000; 95 % CI 1.74-2.42), atypical histology, and non-Caucasian race (OR 1.32; 95 % CI 1.02-1.73). CONCLUSIONS: The use of cross-sectional imaging for staging of early-stage cutaneous melanoma is increasing in the Medicare population. Better dissemination of guidelines and judicious use of imaging should be encouraged.

IMPORTANCE: Programs that analyze and report rates of surgical complications are an increasing focus of quality improvement efforts. The most comprehensive tool currently used for outcomes monitoring in the United States is the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP). OBJECTIVE: To compare surgical outcomes experienced by patients treated at hospitals that did vs did not participate in the NSQIP. DESIGN, SETTING, AND PARTICIPANTS: Data from the University HealthSystem Consortium from January 2009 to July 2013 were used to identify elective hospitalizations representing a broad spectrum of elective general/vascular operations in the United States. Data on hospital participation in the NSQIP were obtained through review of semiannual reports published by the ACS. Hospitalizations at any hospital that discontinued or initiated participation in the NSQIP during the study period were excluded after the date on which that hospital's status changed. A difference-in-differences approach was used to model the association between hospital-based participation in NSQIP and changes in rates of postoperative outcomes over time. EXPOSURE: Hospital participation in the NSQIP. MAIN OUTCOMES AND MEASURES: Risk-adjusted rates of any complications, serious complications, and mortality during a hospitalization for elective general/vascular surgery. RESULTS: The cohort included 345,357 hospitalizations occurring in 113 different academic hospitals; 172,882 (50.1%) hospitalizations were in NSQIP hospitals. Hospitalized patients were predominantly female (61.5%), with a mean age of 55.7 years. The types of procedures performed most commonly in the analyzed hospitalizations were hernia repairs (15.7%), bariatric (10.5%), mastectomy (9.7%), and cholecystectomy (9.0%). After accounting for patient risk, procedure type, underlying hospital performance, and temporal trends, the difference-in-differences model demonstrated no statistically significant differences over time between NSQIP and non-NSQIP hospitals in terms of likelihood of complications (adjusted odds ratio, 1.00; 95% CI, 0.97-1.03), serious complications (adjusted odds ratio, 0.98; 95% CI, 0.94-1.03), or mortality (adjusted odds ratio, 1.04; 95% CI, 0.94-1.14). CONCLUSIONS AND RELEVANCE: No association was found between hospital-based participation in the NSQIP and improvements in postoperative outcomes over time within a large cohort of patients undergoing elective general/vascular operations at academic hospitals in the United States. These findings suggest that a surgical outcomes reporting system does not provide a clear mechanism for quality improvement.

BACKGROUND: Surgeon and hospital factors are associated with the survival of patients treated for rectal cancer. The relative contribution of each of these factors toward determining outcomes is poorly understood. METHODS: We used data from the Surveillance, Epidemiology, and End Results-Medicare database to analyze the outcomes of patients aged 65 years and older undergoing operative treatment for nonmetastatic rectal cancer, diagnosed in the United States between 1998 and 2007. These data were linked to a registry to identify whether the treating surgeon was a board-certified colorectal surgeon versus a noncolorectal surgeon. Hospital volume and hospital certification as a National Cancer Institute-designated Comprehensive Cancer Centers were also analyzed. The primary outcome of interest was long-term survival. RESULTS: Our data source yielded 6432 patients. Initial analysis demonstrated improved long-term survival in patients treated by higher-volume colorectal surgeons, higher-volume hospitals, teaching hospitals, and National Cancer Institute (NCI)-designated Comprehensive Cancer Centers. Based on an iterative approach to modeling the interactions between these various factors, we found a robust effect of surgeon subspecialty status, hospital volume, and NCI designation. Surgeon volume was not distinctly associated with long-term survival. CONCLUSIONS: Patients treated for rectal cancer by board-certified colorectal surgeons in centers that are higher volume and/or NCI-designated Comprehensive Cancer Centers experience better overall survival. These differences persist after adjustment for a broad range of patient and contextual risk factors, including surgeon volume. Patients and payers can use these results to identify surgeons and hospitals where outcomes are most favorable.
