Abstract: Background: Work hour restrictions and new educational standards pose substantial challenges for modern residency programs. We present results from an institutional effort to improve resident education using a competency-based conference program. Methods: The conference program is a weekly 3-hour mandatory block of protected time including a formal lecture series and a modular series tailored to resident level. A comprehensive survey was administered to all general surgery residents before (2005) and after (2006) implementation of the new conference program and included specific items related to the 6 competencies. Results: Scores for 16 competency-related items all showed statistically significant improvement. We also found improvements in residents'' perceptions of the faculty. Overall, the new conference program was rated positively by 98% of residents. Conclusions: Implementation of a structured conference program resulted in significant improvement in residents'' evaluation of their education in the 6 competencies and improved their perceptions of the faculty.

Abstract: Background: Previous research suggests an ostomy worsens health-related quality of life (HR-QOL), but comorbidities also can affect HR-QOL. Methods: Eligible patients had abdominal operation with ostomy (cases) or similar procedure without ostomy (controls). Patients were recruited for this case-control study from 3 Veterans Affairs hospital medical and pharmacy records. Comorbidities were assessed with Charlson-Deyo Comorbidity Index. Multinomial logistic regression evaluated the impact of comorbidities and having an ostomy on HR-QOL, measured using the Medical Outcomes Study Short Form 36 for Veterans. Results: A total of 237 ostomates (cases) and 268 controls were studied. Average age was 69 years; 64% of cases had colostomy, 36% ileostomy. Twenty-nine percent of patients had a high level of comorbidities. Cases and controls were similar except for reasons for undergoing surgery. High comorbidity was a significant predictor of low HR-QOL in 6 domains of the Short Form 36 for Veterans; having an ostomy was a significant predictor in 4. Conclusions: High comorbidity significantly influences low HR-QOL and impacted more domains than having an ostomy. [Copyright &y& Elsevier]

Background: The preoperative diagnosis of acute appendicitis is often inaccurate in pregnant women, and complicated appendicitis is associated with a high rate of fetal loss. The study objective was to evaluate rates of fetal loss and early delivery in pregnant patients undergoing appendectomy, using a large population-based database. Study Design: Using the California Inpatient File, we retrospectively analyzed all women undergoing appendectomy between 1995 and 2002 for pregnancy, diagnosis, operative technique, fetal loss, and early delivery during the same hospitalization as appendectomy. Results: Of 94,789 women who underwent appendectomy, 3,133 were pregnant. Complicated appendicitis was found in 30% of pregnant women and 29% of nonpregnant women (p=NS). The rate of negative appendectomy was considerably higher in pregnant compared with nonpregnant women (23% versus 18%, p < 0.05). Rates of fetal loss and early delivery were considerably higher in women with complex appendicitis (6% and 11% respectively; p < 0.05) in comparison with negative (4% and 10%) and simple (2% and 4%) appendicitis. Using multivariate logistic regression, complicated and negative appendicitis (odds ratio [OR] 2.69 and 1.88 respectively, compared with simple) remained major positive predictors of fetal loss. Also, laparoscopy was associated with a higher rate of fetal loss compared with open appendectomy (odds ratio=2.31). Conclusions: The current approach to possible acute appendicitis in pregnant women puts 23% at risk for fetal loss, even though they have a normal appendix. These data indicate that reducing fetal loss in pregnant women suspected of having acute appendicitis will require more accurate diagnosis to avoid unnecessary operation. [Copyright &y& Elsevier]

Background: Colorectal cancer is the second most common cancer type among new cancer diagnoses in the United States. Attention to the quality of surgical care for colorectal cancer is of particular importance given the increasing numbers of colorectal cancer resections performed in the aging population. A National Cancer Institute-sponsored consensus panel produced guidelines for colorectal cancer surgery in 2000. We have updated and extended that work by using a formal process to identify and rate quality indicators as valid for care during the preoperative, intra- operative, and postoperative periods. Methods: Using a modification of the RAND/UCLA Appropriateness Methodology, we carried out structured interviews with leaders in the field of colorectal cancer surgery and systematic reviews of the literature to identify candidate quality indicators addressing perioperative care for patients undergoing surgery for colorectal cancer. A panel of 14 colorectal surgeons, general surgeons, and surgical oncologists then evaluated and formally rated the indicators using the modified Delphi method to identify valid indicators. Results: A total of 142 candidate indicators were identified in six broad domains: privileging (which addresses surgical credentials), preoperative evaluation, patient-provider discussions, medication use, intraoperative care, and postoperative management. The expert panel rated 92 indicators as valid. These indicators address all domains of perioperative care for patients undergoing surgery for colorectal cancer. Conclusions: The RAND/UCLA Appropriateness Methodology can be used to identify and rate indicators of high-quality perioperative care for patients undergoing surgery for colorectal cancer. The indicators can be used as quality performance measures and for quality-improvement programs. [ABSTRACT FROM AUTHOR]

Quality indicators will likely be used in comprehensive surgical quality assessment and improvement programs. Quality indicators are the actions equated with good quality of care. As a case example, bariatric surgery quality indicators were developed using evidence in the literature combined with formal expert opinion validation. Qualitative analysis was performed to identify the critical thematic issues surrounding development of these surgical quality indicators. Researchers identified five major thematic categories during the development process. These included feasibility in medical records (availability, ease of abstraction, and cost), the number of indicators developed (optimal number), the lack of evidence in the literature (weight on expert opinion), structural versus process indicators, and linkage to outcomes (need to demonstrate that adherence to indicators is associated with better outcomes). This project, using bariatric surgery as an example, uncovered important issues that need to be addressed when developing quality assessment and quality improvement programs for evaluating surgical quality. As quality indicators will likely be developed and used increasingly, future projects in this regard will benefit from these lessons. [ABSTRACT FROM AUTHOR]

Background: Small bowel obstruction (SBO) is a common reason for surgical consultation, but little is known about the natural history of SBO. We performed a population-based analysis to evaluate SBO frequency, type of operation, and longterm outcomes. Study design: Using the California Inpatient File, we identified all patients admitted in 1997 with a diagnosis of SBO. Patients were excluded if they had a diagnosis of bowel obstruction in the previous 6 years (1991 to 1996). Of the remaining cohort, the natural history of SBO over the subsequent 5 years (1998 to 2002) was analyzed. Index hospitalization outcomes (eg, surgical versus nonsurgical management, length of stay, in-hospital mortality), and longterm outcomes, including SBO readmissions and 1-year mortality, were evaluated. Results: We identified 32,583 patients with an index admission for SBO in 1997; 24% had surgery during the index admission. The distribution of surgical procedures was: 38% lysis of adhesions, 38% hernia repair, 18% small bowel resection with lysis of adhesions, and 6% small bowel resection with hernia repair. Patients who underwent operations during index admission had longer lengths of stay, lower mortality, fewer SBO readmissions, and longer time to readmission than patients treated nonsurgically. Regardless of treatment during the index admission, 81% of surviving patients had no additional SBO readmissions over the subsequent 5 years. Conclusions: Most of the 32,583 patients requiring admission for index SBO in 1997 were treated nonsurgically, and few of these patients were readmitted. This is the first longitudinal population-based analysis of SBO evaluating surgical versus nonsurgical management and outcomes, including mortality and readmissions. [Copyright &y& Elsevier]

Background: Although the expanding and aging population will likely increase demand for surgical services, surgeons and other providers must develop strategies to optimize care. We sought to develop process-based quality indicators for elderly patients undergoing abdominal operations to identify necessary and meaningful ways to improve care in this cohort. Study design: Through structured interviews with thought leaders and systematic reviews of the literature, we identified candidate quality indicators addressing perioperative care in elderly patients undergoing abdominal operations. Using a modification of the RAND/UCLA Appropriateness Methodology, an expert panel of physicians in surgery, geriatrics, anesthesia, internal, and rehabilitation medicine formally rated and discussed the indicators. Results: Eighty-nine candidate indicators were identified and categorized into seven domains: comorbidity assessment (eg, cardiopulmonary disease), elderly issues (eg, cognition), medication use (eg, polypharmacy), patient-to-provider discussions (eg, life-sustaining preferences), intraoperative care (eg, preventing hypothermia), postoperative management (eg, preventing delirium), and discharge planning (eg, home health care). Of the 89 candidate indicators, 76 were rated as valid by the expert panel. Importantly, the majority of indicators rated as valid address processes of care not routinely performed in younger surgical populations. Conclusions: Attention to the quality of surgical care in elderly patients is of great importance because of the increasing numbers of elderly undergoing operations. This project used a validated methodology to identify and rate process measures to achieve high-quality perioperative care for elderly surgical patients. This is the first time quality indicators have been developed in this regard. [Copyright &y& Elsevier]

Context The use of Roux-en-Y gastric bypass (RYGB) has been reported to be effective in the treatment of obesity and its related comorbidities. Utilization of inpatient services after RYGB is less well understood. Objective To determine the rates and indications for inpatient hospital use before and after RYGB. Design, Setting, and Participants Retrospective study of Californians receiving RYGB in California hospitals from 1995 to 2004. Main Outcome Measure Hospitalization in the 1 to 3 years after RYGB. Results In California from 1995 to 2004, 60 077 patients underwent RYGB—11 659 in 2004 alone. The rate of hospitalization in the year following RYGB was more than double the rate in the year preceding RYGB (19.3% vs 7.9%, P<.001). Furthermore, in the subset of patients (n = 24 678) with full 3-year follow-up, a mean of 8.4% were admitted a year before RYGB while 20.2% were readmitted in the year after RYGB, 18.4% in the second year after RYGB, and 14.9% in the third year after RYGB. The most common reasons for admission prior to RYGB were obesity-related problems (eg, osteoarthritis, lower extremity cellulitis), and elective operation (eg, hysterectomy), while the most common reasons for admission after RYGB were complications often thought to be procedure related, such as ventral hernia repair and gastric revision. In multivariate logistic regression models predicting 1-year readmission after RYGB, increasing Charlson Comorbidity Index score, and hospitalization in the 3-year period prior to RYGB were significantly associated with readmission within a year. Conclusions Increases in hospital use after surgery appear to be related to RYGB. Payers, clinicians, and patients must consider the not-inconsequential rate of rehospitalization after this type of surgery. [ABSTRACT FROM AUTHOR]

Negative appendectomy rate varies significantly depending on patient age and sex. However, the impact of computed tomography (CT) scans on the diagnosis of appendicitis is unknown. The goal of this study was to examine the negative appendectomy rate using a statewide database and analyze the association of receipt of CT scan. Using the California Inpatient File, all patients undergoing appendectomy in 1999-2000 were identified (n = 75,452). Demographic and clinical data were analyzed, including procedure approach (open vs laparoscopic) and appendicitis type (negative, simple, abscess, peritonitis). Patients with CT scans performed were identified to compare the negative appendectomy rate. For the entire cohort, appendicitis type was 59 per cent simple, 10 per cent with abscess, 18.7 per cent with peritonitis, and 9.3 per cent negative. Males had a lower rate of negative appendicitis than females (6.0% vs 13.4%, P < 0.0001). The use of CT scans was associated with an overall lower negative appendectomy rate for females, especially in the < 5 years and > 45 years age categories. Use of CT scans in males does not appear to be efficacious, as the negative appendectomy rates were similar across all age categories. In conclusion, use of CT was associated with lower rate of negative appendectomy, depending on patient age and sex. [ABSTRACT FROM AUTHOR]

The article presents a medical study looking at the patient characteristics connected to the utilization of high-volume hospitals for complex surgery. Information for the study was gathered for inpatient operations, such as abdominal aortic aneurysm repair, cardiac valve replacement, and total knee replacement, from California's Office of Statewide Health Planning and Development patient discharge database. The study found that in general uninsured, Medicaid, and nonwhite patients were less likely to receive medical care at high-volume hospitals and more like to receive care at low-volume hospitals.

Background: Chart abstraction is a common method for measuring the quality of surgical care. In this study we examine how the use of standardized operative dictation and history forms improves documentation rates of bariatric quality measures. Materials and methods: Two independent reviewers evaluated 201 patient charts from two multi-surgeon bariatric surgery practices for documentation of five intraoperative and seven preoperative bariatric quality measures. Group 1 used fully standardized templates to dictate or collect both, while Group 2 did not. Documentation rates were compared between the groups. Results: Operative reports more consistently documented quality assessment information for cases where a dictation template was used versus where it was not (89% versus 58%, respectively, P < 0.001). The greatest discrepancies between the two groups were found in “exploration of the abdomen” (95% in Group 1 versus 43% in Group 2, P < 0.001) and in “evaluation of the gallbladder” (76% versus 28%, P < 0.001). In comparison, overall documentation rates for preoperative comorbidities were greater in both groups but remained higher for Group 1, who used fully standardized forms (98% versus 74%, P < 0.001). Group 1 had statistically significant higher rates of documentation for all seven comorbidities. Conclusions: The use of standardized dictation templates and history forms is associated with significantly higher documentation rates of quality measures in bariatric surgery. The adoption of these methods into routine use will be needed to allow for wide scale quality assessment and improvement for surgical practices. [Copyright &y& Elsevier]

Most literature available on rare colorectal cancer (CRC) is from case series reports. This population-based evaluation is the first comprehensive look at four rare histologic types of CRC, allowing comparisons with the more common adenocarcinoma for clinical and pathological features and survival rates. All patients diagnosed with carcinoid ( n=2,565), malignant lymphoma ( n=955), non-carcinoid neuroendocrine ( n=455), squamous cell ( n=437), and adenocarcinoma ( n=164,638) in SEER cancer database (1991–2000) were analyzed. Evaluation of age-adjusted incidence rate, stage at presentation, and 5-year relative survival were determined for each histologic subtype. All rare histologic subtypes had younger mean age than adenocarcinomas (70 years; p<0.05). Lymphoma was more common in males (65.1%; P<0.01). Incidence rates in 2000 per million were: carcinoid 10.6, lymphoma 3.5, neuroendocrine 2.0, squamous 1.9, and adenocarcinoma 496.3. The annual percent change in incidence for each rare tumor increased significantly during the 10 years (range: 3.1–9.4%, p<0.05), except squamous cell carcinoma (5.9%, p>0.05). Squamous (93.4%) and carcinoid (73.7%) tumors occurred more often in the rectum; lymphoma (79.0%), neuroendocrine (70.8%), and adenocarcinoma (70.1%) occurred more often in the colon ( P<0.01). Carcinoids presented at earlier stage (localized/regional, 90.5%) more often than adenocarcinoma (80.6%; p<0.01), but squamous cell (82.1%; p=0.50), lymphoma(70.6%; p<0.01), and neuroendocrine (37.8%; p<0.01) presented at earlier stage similarly or less often than adenocarcinoma. Relative 5-year survival rate was highest for carcinoid (91.3%), and lowest for neuroendocrine tumors (21.4%). This study provides the first population-based analysis of the epidemiology, tumor characteristics, and survival rates for rare CRC. [ABSTRACT FROM AUTHOR]
