Effect of an acute care surgical service on the timeliness of care

Andrea M. Faryniuk; David J. Hochman

BACKGROUND In the spring of 2008, St. Boniface General Hospital in Winnipeg, Man., created an acute care surgical service (ACSS) designed to improve care for emergent, nontrauma surgical patients. We sought to assess the effect of the ACSS on patient care timeliness. METHODS We retrospectively examined the time intervals in care for patients admitted with acute appendicitis, acute cholecystitis and small bowel obstruction in 3 study periods: pre-ACSS, newly formed ACSS and established ACSS. RESULTS There was a 2-fold increase in patient volume after the ACSS was created. Patient characteristics were similar in all 3 groups. Time from triage to surgical consultation was also similar. The ACSS significantly reduced the duration of the surgical consultation (1 h 43 min in period 1 v. 62 min in period 2 and 49 min in period 3, p = 0.029). Time from admission to operation was similar despite a significant increase in patient load after the ACSS was created. Total length of hospital stay was similar except in the subgroup analysis (appendicitis + cholecystitis only), where the length of stay was reduced after creation of the ACSS (2 d 15 h pre- v. 1 d 19 h post-ACSS, p = 0.009). Most operations occurred between 4 pm and midnight. CONCLUSION With the implementation of an ACSS, the number of surgical patients assessed and treated doubled. Despite the increased volume, consultations were completed significantly faster, there was no significant difference in time to operation, and on subgroup analysis length of hospital stay was significantly faster.

Implementation of best practices surgical checklists improves patient safety and outcomes. However, documenting performance of these practices can be challenging. The American Society of Colon and Rectal Surgeons developed a Best Practices for Rectal Cancer Checklist (RCC) to standardize and improve the quality of rectal cancer surgery. This study compared the degree to which synoptic (SR) and narrative (NR) operative reports document RCC items.

BACKGROUND: Challenges exist in providing high-quality cancer treatments to populations spread over large geographical areas. Local recurrence of rectal cancer is a complicated clinical problem associated with high morbidity and mortality. OBJECTIVES: The objectives of this study were to evaluate population-based rates and predictors of local recurrence of rectal cancer in the Province of Manitoba, Canada, with emphasis on the effects of geography. DESIGN: This was a population-based retrospective analysis. Administrative data from the Manitoba Cancer Registry and individual patient charts were reviewed. SETTINGS: Patients with stages I to III rectal cancer who underwent surgery with curative intent in Manitoba between 2004 and 2006 were included. MAIN OUTCOME MEASURES: The primary outcome was the development of local recurrence after surgical resection. RESULTS: Three hundred seventy patients with a mean age of 67 years were identified. The 5-year local recurrence rate was 17.4%. In multivariate analysis, relative to Winnipeg residents, rural residents, regardless of where they underwent surgery, had an increased risk of local recurrence (HR, 3.47; 95% CI, 1.74–6.92 for surgery in Winnipeg; HR, 2.98; 95% CI, 1.59–5.57 for surgery in rural Manitoba). The absence of both neoadjuvant radiotherapy and adjuvant chemotherapy was associated with a higher risk of local recurrence. Higher risk of mortality was noted for rural patients (HR, 1.90; 95% CI, 1.24–2.89) and for those who developed local recurrence (HR, 2.01; 95% CI, 1.27–3.19). CONCLUSION: Local recurrence rates for rectal cancer are high in Manitoba. Geography is an important variable, because rural status is associated with higher local recurrence rates and decreased survival. The use of neoadjuvant radiotherapy was an important predictor of lower local recurrence rates. Further initiatives are imperative to identify why rural patients experience differences in outcomes in Manitoba.

Evaluation of a Regional Acute Care Surgery Service by Residents in General Surgery

BACKGROUND Acute care surgery (ACS) services dedicated to care of acute general surgery patients have been established in many tertiary centers across Canada. Little is known about the impact of this trend on postgraduate education. In this study we aimed to evaluate ACS through a cross-sectional survey of general surgery residents in Winnipeg, Manitoba. METHODS General surgery residents at the University of Manitoba were asked to complete an anonymous survey. Basic demographic data were obtained. The educational value of ACS was assessed using 10 statements derived from the CanMEDS framework for training physicians. Resident burnout was measured using the Maslach Burnout Inventory, on emotional exhaustion, depersonalization, and personal accomplishment. RESULTS The response rate was 70% (14/20). ACS was evaluated positively based on the CanMEDS roles by the following proportions of responders: surgical skills (79%), clinical knowledge (100%), communicator (100%), collaborator (100%), manager (86%), health advocate (100%), scholar (64%), and professional (93%). Fifty percent of responders had a high score on emotional exhaustion, 43% on depersonalization, and 0% on low sense of personal accomplishment. The overall burnout was 64%. CONCLUSIONS ACS provides a comprehensive clinical experience based on the CanMEDS competencies. Despite an increased sense of personal accomplishment, residents experienced a high incidence of burnout, as demonstrated by high scores on emotional exhaustion and depersonalization of patients.

BackgroundThe Canadian province of Manitoba covers a large geographical area but only has one major urban center, Winnipeg. We sought to determine if regional differences existed in the quality of colorectal cancer care in a publicly funded health care system.MethodsThis was a population-based historical cohort analysis of the treatment and outcomes of Manitobans diagnosed with colorectal cancer between 2004 and 2006. Administrative databases were utilized to assess quality of care using published quality indicators.ResultsA total of 2,086 patients were diagnosed with stage I to IV colorectal cancer and 42.2% lived outside of Winnipeg. Patients from North Manitoba had a lower odds of undergoing major surgery after controlling for other confounders (odds ratio (OR): 0.48, 95% confidence interval (CI): 0.26 to 0.90). No geographic differences existed in the quality measures of 30-day operative mortality, consultations with oncologists, surveillance colonoscopy, and 5-year survival. However, there was a trend towards lower survival in North Manitoba.ConclusionWe found minimal differences by geography. However, overall compliance with quality measures is low and there are concerning trends in North Manitoba. This study is one of the few to evaluate population-based benchmarks for colorectal cancer therapy in Canada.

Wait times are a growing concern in Canadas publicly‐funded healthcare system. We sought to determine if increased wait times for colorectal cancer (CRC) treatments resulted in worse outcomes.

Is obesity associated with advanced stage or grade of colon cancer

Katerina Neumann; Salaheddin M. Mahmud; Andrew McKay; Jason Park; Jennifer Metcalfe; David J. Hochman

Population-based studies from Europe have suggested that obesity is associated with more advanced stage colorectal cancer on presentation. Obesity is an even more prevalent issue in North America, but comparable data on associations with cancer are lacking. We reviewed the cases of 672 patients with colon cancer diagnosed between 2004 and 2008 in the province of Manitoba who underwent surgical resection at a Winnipeg Regional Health Authority–affiliated hospital. We tested if obesity was associated with more advanced cancer stage or grade. On multivariate analysis, after adjusting for age, sex,tumour location and socioeconomic status, we were unable to show any significant associations between body mass index of 30 or more and advanced stage or grade cancer on presentation. The reasons for the lack of association are likely multifactorial, including the pathophysiology of the disease and process factors, such as screening habits and colonoscopic diagnostic success rates in obese patients.
