Administrative data are routinely captured for each hospital admission and may serve as an alternative source for populating databases. This study aims to determine the accuracy of administrative data to provide tumour characteristics and short-term post-operative outcomes, after a colorectal cancer (CRC) resection, compared with clinical data.A retrospective study of all CRC resections at a single hospital from 1 January 2008 to 31 December 2013 was conducted. Local administrative data were coded as per ICD-10-AM (International Classification of Diseases, Tenth Revision, Australian Modification) and Australian Classification of Health Interventions. Clinical data for all patients were extracted from the medical charts and compared with administrative data. Code combinations and algorithms were used to improve the accuracy of administrative data.A total of 436 patients were identified. The accuracy of algorithms combining tumour location and type of operation for right colon, left colon and rectum were 93, 89 and 88%, respectively. The accuracy of histological type was 89%, lymph node status 92% and metastasis status 88%. The accuracy of return to theatre and in-hospital mortality was 100%.Administrative data can provide reliable information on tumour details and short-term post-operative outcomes. The potential for administrative data to validate data captured in registries and be used independently for audit and research should be further explored.

Reoperation rates after breast-conserving surgery are highly variable and the best techniques for optimizing margin clearance are being evaluated. The aim was to identify the reoperation rate at our centre and identify influential factors, including a change in guidelines on margin recommendations and the introduction of in-theatre specimen X-ray.A retrospective review of medical records was undertaken to identify 562 patients who underwent breast conservation at The Royal Melbourne Hospital and Royal Women's Hospital between 2013 and 2015. All cases that underwent subsequent re-excision or total mastectomy were captured and factors influencing margin excision recorded.Reoperation was undertaken in 19.5% of patients (110; 86 re-excisions and 24 total mastectomies). There was a reduction in reoperation rate from 25% to 17% (P = 0.01) with adoption of the margin guidelines in 2014, but no significant reduction with the introduction of in-theatre specimen X-ray in 2015 (21% versus 16%, P = 0.14). On multivariate analysis, factors that significantly influenced reoperation rates were the presence of multifocality on mammogram (odds ratio (OR): 5.3, 95% confidence interval (CI): 1.6-16.7, P0.01); lesion size on mammogram (OR: 2.2 per 10 mm, 95% CI: 1.4-3.6, P0.01); smaller excision specimen weight (OR: 0.5 per 25 g of resection, 95% CI: 0.3-0.8, P0.01); and pure ductal carcinoma in situ on final pathology (OR: 5.9, 95% CI: 1.9-16.7, P0.01).Optimizing reoperation rates following breast-conserving surgery remains a surgical challenge, particularly in patients with in situ or multifocal disease. Adoption of international margin guidelines reduced reoperation rates at our centre; however, introduction of intraoperative specimen X-ray had no influence.

Idiopathic granulomatous mastitis (IGM) is a rare benign breast disease, which can be protracted, disfiguring and may be linked to an underlying autoimmune disorder. The clinical presentation may mimic bacterial mastitis or carcinoma.To review the mode of presentation, diagnosis, management, resolution and incidence of IGM in three tertiary breast centres and propose guidelines for management.The breast and anatomical databases of three centres were reviewed from January 2000 to December 2013 to identify patients with histological diagnosis of IGM. Clinical and demographic characteristics were retrieved and treatment modalities and time to resolution were recorded.Seventeen patients were identified with a median age of 40. The majority of patients were premenopausal, multiparous and presented with a mass. All patients had initial treatment as infectious mastitis. The diagnosis was made by core biopsy in 71%. Eleven patients required immunosuppressive treatment with steroids and four of these patients required a steroid-sparing agent because of steroidal side effects, recurrence or persistence of symptoms. The median time to resolution was 3 months (0-24 months). One patient had subsequent systemic Wegener's granulomatosis diagnosed.Idiopathic granulomatosis mastitis requires histological confirmation, close monitoring, exclusion of underlying systemic autoimmune conditions and judicious use of steroids and steroid-sparing agents such as methotrexate. It has a protracted course with some patients relapsing quickly upon cessation of steroids.

Educational programmes are frequently developed to improve the knowledge of medical trainees. The impact of a programme may be limited if there is no follow-up to reinforce the message. Online Spaced Education (SE) has been developed to address this limitation. This study was performed to assess whether an SE programme would improve the impact of a didactic seminar.A randomized trial of an online SE programme occurred as part of the 2010 Clinical Oncology Society of Australia Breast Cancer Trainee Workshop. Consenting participants were randomized to undertake SE or not and were then invited to undertake a 22-question knowledge test. A questionnaire was administered relating to the perceived value of the SE programme. Participants consisted largely of surgical and medical oncology trainees.Two hundred people attended the workshop and 97 consented to randomization. Thirty-eight of 49 randomized to the SE group commenced the SE course. Seventy-one percent of participants answered each question at least once and 55% of participants completed the entire programme. Fifty-nine participants completed the post-test. The SE participants performed significantly better than the control group (P0.05). The questionnaire was completed by 26 of the SE group. Ninety-two percent strongly agreed or agreed that SE would improve their practice and 96% agreed that SE effectively reinforced key aspects of workshop.This study demonstrates the utility of SE to increase knowledge retention following a face-to-face workshop. The programme was very well received by the participants and may be an appropriate reinforcing methodology for other similar seminars.
