Enhancing the quality of care for patients with breast cancer: Seven years of experience with a Dutch auditing system
Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures
Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo
Enhancing the quality of care for patients with breast cancer: Seven years of experience with a Dutch auditing system
Background: Hospitals in the Midwestern part of the Netherlands carried out a clinical audit to monitor the quality of breast cancer care during the years 2002-2008. Compliance with the National Guideline was investigated together with improvement in quality over time. Methods: Patients with a malignancy of the breast (including ductal carcinoma in situ) participated in this study. Nine quality indicators were evaluated over the years. In 2004 and 2005 the hospitals also carried out an intervention project aimed at improvement of the efficiency of both the diagnostic process and the surgical treatment. Results: At the end of the project all nine indicators showed significant improvement compared to the start of the project. Discussion of treatment strategy in a multidisciplinary breast cancer team took place more often before surgery (83% versus 56%) as well as after surgery (98% versus 70%). The National Guideline for maximum waiting times was met more often for the outpatient clinic (74% versus 61%), time to diagnosis (92% versus 82%), and surgical treatment (52% versus 34%). More sentinel node procedures were performed successfully (92% versus 69%), and for more patients more than 10 lymph nodes were evaluated in case of axillary lymph node dissection (85% versus 58%). More patients had definitive surgical treatment consisting of one surgical intervention (87% versus 75%), and left the hospital within 7 days after hospital admission (98% versus 66%). Conclusion: The clinical audit contributed to improvement of the quality of breast cancer care in the Midwestern part of the Netherlands between 2002 and 2008. (C) 2011 Elsevier Ltd.

Early closure of a multicenter randomized clinical trial of endoscopic stenting versus surgery for stage IV left-sided colorectal cancer.
Item does not contain fulltextBACKGROUND AND STUDY AIMS: The introduction of self-expandable metal stents has offered a promising alternative for palliation of malignant left-sided colonic obstruction. This randomized clinical trial aimed to assess whether a nonsurgical policy, with endoluminal stenting, is superior to surgical treatment in patients with stage IV left-sided colorectal cancer and imminent obstruction. PATIENTS AND METHODS: Patients with incurable left-sided colorectal cancer who fulfilled the study criteria were randomly assigned to nonsurgical or surgical treatment. The primary outcome measure was survival in good health out of hospital (World Health Organization performance scores 0 or 1). RESULTS: A high number of serious adverse events in the nonsurgical arm led to premature closure of the trial. Ten patients were allocated to surgical treatment and 11 patients to nonsurgical palliation. The median survival in good health out of hospital during the first year was 56 days (interquartile range 7.5 - 338.5 days) in the surgical arm vs. 38 days (interquartile range 5.25 - 288.75 days) in the nonsurgical arm (P = 0.68). Eleven adverse events (six perforations) occurred in the nonsurgical arm vs. one adverse event in the surgical arm (P < 0.001). Of the six perforations, two were stent-related because they occurred at the proximal edge of the stent by erosion through a normal colon wall; one was probably stent-related (it was located in the region of the proximal half of the stent); one was a colon blowout; and two were late tumor perforations in patients on chemotherapy. CONCLUSIONS: The unexpected high rate of perforation in the nonsurgical arm might be specifically WallFlex-related or enteral stent-related in patients on chemotherapy and warrants attention

Risk of Regional Recurrence After Negative Repeat Sentinel Lymph Node Biopsy in Patients with Ipsilateral Breast Tumor Recurrence
Repeat sentinel lymph node biopsy (rSLNB) has increasingly been used in patients with ipsilateral breast tumor recurrence (IBTR). The safety in terms of regional disease control after this procedure remains unclear. This study evaluates occurrence of regional recurrence as first event in patients with IBTR and negative rSLNB, treated without additional lymph node dissection. Data were obtained from the Sentinel Node and Recurrent Breast Cancer (SNARB) study. In 201 patients, tumor-negative rSLNB was obtained without performing additional lymph node dissections. 99mtechnetium) used during rSLNB were associated with developing regional recurrence as first event after negative rSLNB (P < 0.05). The risk of developing regional recurrence after negative rSLNB is low. The low relapse rate supports the safety of rSLNB as primary nodal staging tool in IBTR. The time has come for clinical guidelines to adopt rSLNB as axillary staging tool in patients with IBT
