Quality measures in breast cancer surgery.

The development of accurate quality performance measures in breast cancer surgery is extremely challenging as highlighted by Monica Morrow in a recent editorial. Traditional quality measures in surgical oncology have focused on 30-day morbidity and mortality which are not relevant to breast cancer surgery which is typically associated with low morbidity and mortality. Dr Morrow suggests that the recent study by McCahill et al which uses re-excision of margins following breast conserving surgery (BCS) as an indicator of surgical quality fails the lithmus test as a quality measure for a variety of reasons. Essentially, there are too many variables that may influence the decision to proceed with breast conserving surgery in the first place such as patients’ age, surgeons’ bias and appropriate preoperative imaging. Using re-excision of margins as a tool to measure quality would encourage breast surgeons to perform a wider excision than is oncologically necessary and compromise the aesthetic appearance of the breast. In addition the quality of pathological margin processing may also vary considerably between institutions. It is therefore essential that any proposed quality measure in breast cancer surgery is evidence based and compliments our understanding of modern breast cancer biology. It is equally important that any proposed quality indicator is reliable and appropriately validated and is cost-effective in terms of collecting the relevant data

Breaking Barriers to Successful Implementation of Day Case Laparoscopic Cholecystectomy.

Laparoscopic cholecystectomy is a common procedure performed in both emergency and elective settings. Our aim was to analyse the trends in laparoscopic surgery in Ireland in the public and private healthcare systems. In particular we studied the trend in day case laparoscopic cholecystectomy. National HIPE data for the years 2010-2012 was obtained. Similar datasets were obtained from the three main health insurers. 19,214 laparoscopic cholecystectomies were carried out in Ireland over the 3-year period. More procedures were performed in the public system than the private system from 2010-2012. There was a steady increase in surgeries performed in the public sector, while the private sector remained static. Although the ALOS was significantly higher in the public sector, there was an increase in the rate of day case procedures from 416 (13%) to 762 (21.9%). The day case rates in private hospitals increased only slightly from 29 (5.1%) in 2010 to 40 (5.9%) in 2012. Day case laparoscopic cholecystectomy has been shown to be a safe procedure, however significant barriers remain in place to the implementation of successful day case units nationwide

Preparing students to be doctors: introduction of a sub-internship program.

Preparing graduates for the transformation from medical student to doctor provides medical schools with a real challenge. Medical educators advocate a process of graduated delegation of responsibility in the clinical years of medical school. This is best exemplified in the North American system of sub-internship programmes; an educational approach which European medical schools have been slow to adopt. This study reports on the introduction of an intensive two-week surgical sub-internship for final medical year students. \u22Sub-interns\u22 were asked to complete pre and post sub-internship online questionnaires assessing their readiness to perform clinical and practical skills, attitudes towards the program, and how well it prepared students for internship. Forty-nine students completed a questionnaire pre sub-internship and 47 completed the post-questionnaire. Student confidence towards practical and clinical skills and their first day at work increased over the two weeks. Mean Iikert scores for all 6 practical and clinical skills improved post sub-internship. The introduction of a surgical sub-internship is timely and welcomed by medical students. Its development helps bridge the gap in responsibilities between medical student and doctor

Prevalence and predictors of initial oral antibiotic treatment failure in adult emergency department patients with cellulitis: a pilot study.

INTRODUCTION: Assessment of cellulitis severity in the emergency department (ED) setting is problematic. Given the lack of research performed to describe the epidemiology and management of cellulitis, it is unsurprising that heterogeneous antibiotic prescribing and poor adherence to guidelines is common. It has been shown that up to 20.5% of ED patients with cellulitis require either a change in route or dose of the initially prescribed antibiotic regimen. The current treatment failure rate for empirically prescribed oral antibiotic therapy in Irish EDs is unknown. The association of patient risk factors with treatment failure has not been described in our setting. Lower prevalence of community-acquired methicillin-resistant Staphylococcus aureus-associated infection, differing antibiotic prescribing preferences and varying availability of outpatient intravenous therapy programmes may result in different rates of empiric antibiotic treatment failure from those previously described. METHODS AND ANALYSIS: Consecutive ED patients with cellulitis will be enrolled on a 24/7 basis from 3 Irish EDs. A prespecified set of clinical variables will be measured on each patient discharged on empiric oral antibiotic therapy. A second independent study recruiter will assess at least 10% of cases for each of the predictor variables. Follow-up by telephone call will occur at 14 days for all discharged patients where measurement of the primary outcome will occur. Our primary outcome is treatment failure, defined as a change in route of antibiotic administration from oral to intravenous antibiotic. Our secondary outcome is change in dose or type of prescribed antibiotic. A cohort of approximately 152 patients is required to estimate the proportion of patients failing oral antibiotic treatment with a margin of error of 0.05 around the estimate. ETHICS AND DISSEMINATION: Full ethics approval has been granted. An integrated dissemination plan, involving diverse clinical specialties and enrolled patients, is described. TRIAL REGISTRATION NUMBER: NCT 02230813

Using Social Media to Increase Accessibility to Online Teaching Resources.

The key learning points of Surgical Grand Rounds (SGR) are often not accessible at times of exam revision for students. We sought to use Twitter as an online teaching repository. A SGR Twitter profile was created. 23 SGR presentations were made accessible on Twitter over a 3 month period. 93 students were invited to complete a questionnaire assessing usage of the repository. 84 (90%) in total responded, of these, 25 (80.6%) felt that the online provision of SGR through twitter was useful . The majority (71%) felt that the online content was easily accessible. The novel use of social media is a useful adjunctive educational tool in accessing an online repository of SGR presentations

Preventing infection in general surgery: improvements through education of surgeons by surgeons.

Surgical patients are at particular risk of healthcare-associated infection (HCAI) due to the presence of a surgical site leading to surgical site infection (SSI), and because of the need for intravascular access resulting in catheter-related bloodstream infection (CRBSI). A two-year initiative commenced with an initial audit of surgical practice; this was used to inform the development of a targeted educational initiative by surgeons specifically for surgical trainees. Parameters assessed during the initial audit and a further audit after the educational initiative were related to intra- and postoperative aspects of the prevention of SSIs, as well as care of peripheral venous catheters (PVCs) in surgical patients. The proportion of prophylactic antibiotics administered prior to incision across 360 operations increased from 30.0% to 59.1% (P72h (10.6% vs 3.1%,

Prosaposin activates the androgen receptor and potentiates resistance to endocrine treatment in breast cancer.

INTRODUCTION: HOX genes play vital roles in growth and development, however, atypical redeployment of these genes is often associated with steroidal adaptability in endocrine cancers. We previously identified HOXC11 to be an indicator of poor response to hormonal therapy in breast cancer. In this study we aimed to elucidate genes regulated by HOXC11 in the endocrine resistant setting. METHODS: RNA-sequencing paired with transcription factor motif-mapping was utilised to identify putative HOXC11 target genes in endocrine resistant breast cancer. Validation and functional evaluation of the target gene, prosaposin (PSAP), was performed in a panel of endocrine sensitive and resistant breast cancer cell lines. The clinical significance of this finding was explored in clinical cohorts at both mRNA and protein level. RESULTS: PSAP was shown to be regulated by HOXC11 in both tamoxifen and aromatase inhibitor (AI) resistant cell lines. Transcript levels of HOXC11 and PSAP correlated strongly in samples of primary breast tumours (r = 0.7692, n = 51). PSAP has previously been reported to activate androgen receptor (AR) in prostate cancer cells. In a panel of breast cancer cell lines it was shown that endocrine resistant cells exhibit innately elevated levels of AR compared to their endocrine sensitive counterparts. Here, we demonstrate that stimulation with PSAP can drive AR recruitment to a hormone response element (HRE) in AI resistant breast cancer cells. Functionally, PSAP promotes cell migration and invasion only in AI resistant cells and not in their endocrine sensitive counterparts. In a cohort of breast cancer patients (n = 34), elevated serum levels of PSAP were found to associate significantly with poor response to endocrine treatment (p = 0.04). Meta-analysis of combined PSAP and AR mRNA are indicative of poor disease-free survival in endocrine treated breast cancer patients (hazard ratio (HR): 2.2, P = 0.0003, n = 661). CONCLUSION: The HOXC11 target gene, PSAP, is an AR activator which facilitates adaptation to a more invasive phenotype in vitro. These findings have particular relevance to the development of resistance to AI therapy which is an emerging clinical issue. PSAP is a secreted biomarker which has potential in identifying patients failing to exhibit sustained response to hormonal treatment

Assessing the functional performance of post-call hospital doctors using a Nintendo Wii.

Sleep deprivation is an established part of the working life for Non-Consultant Hospital Doctors (NCHDs) in Ireland. Concern exists about the effect of extended NCHD work hours. We utilised a Nintendo Wii to evaluate motor function of NCHDs both prior to their on-call shift and the day afterwards. Data was exported to SPSS ver. 15 for statistical analysis with p \u3c 0.05 considered significant. A total of 72 NCHDs were invited to participate in this study. There was a 62.5% (45) rate of follow-up. Overall 27 (60%) NCHDs were on medical call, with 18 (40%) on surgical call. There was no statistically significant difference between NCHDs pre-and post-call motor assessment scores. The majority of study participants (75.5%, n = 34) had four or more hours sleep. On-call duty allows for a greater than anticipated amount of sleep per on-call shift and therefore has a negligible effect on the motor skills of medical staff

A targeted e-learning program for surgical trainees to enhance patient safety in preventing surgical infection.

INTRODUCTION: Surgical site infection accounts for 20% of all health care-associated infections (HCAIs); however, a program incorporating the education of surgeons has yet to be established across the specialty. METHODS: An audit of surgical practice in infection prevention was carried out in Beaumont Hospital from July to November 2009. An educational Web site was developed targeting deficiencies highlighted in the audit. Interactive clinical cases were constructed using PHP coding, an HTML-embedded language, and then linked to a MySQL relational database. PowerPoint tutorials were produced as online Flash audiovisual movies. An online repository of streaming videos demonstrating best practice was made available, and weekly podcasts were made available on the iTunes© store for free download. Usage of the e-learning program was assessed quantitatively over 6 weeks in May and June 2010 using the commercial company Hitslink. RESULTS: During the 5-month audit, deficiencies in practice were highlighted, including the timing of surgical prophylaxis (33% noncompliance) and intravascular catheter care in surgical patients (38% noncompliance regarding necessity). Over the 6-week assessment of the educational material, the SurgInfection.com Web pages were accessed more than 8000 times; 77.9% of the visitors were from Ireland. The most commonly accessed modality was the repository with interactive clinical cases, accounting for 3463 (43%) of the Web site visits. The average user spent 57 minutes per visit, with 30% of them visiting the Web site multiple times. DISCUSSION: Interactive virtual cases mirroring real-life clinical scenarios are likely to be successful as an e-learning modality. User-friendly interfaces and 24-hour accessibility will increases uptake by surgical trainees

Utility of repeat cytological assessment of thyroid nodules initially classified as benign: clinical insights from multidisciplinary care in an Irish tertiary referral centre.

BACKGROUND: Fine needle aspiration biopsy (FNAB) is the tool of choice for evaluating thyroid nodules with the majority classified as benign following initial assessment. However, concern remains about false negative results and some guidelines have recommended routine repeat aspirates. We aimed to assess the utility of routine repeat FNAB for nodules classified as benign on initial biopsy and to examine the impact of establishing a multidisciplinary team for the care of these patients. METHODS: We performed a retrospective review of 400 consecutive patients (413 nodules) who underwent FNAB of a thyroid nodule at our hospital between July 2008 and July 2011. Data recorded included demographic, clinical, histological and radiological variables. RESULTS: Three hundred and fifty seven patients (89 %) were female. Median follow-up was 5.5 years. Two hundred and fifty eight (63 %) nodules were diagnosed as benign. The rate of routine repeat biopsy increased significantly over the time course of the study (p for trend = 0.012). Nine Thy 2 nodules were classified differently on the basis of routine repeat biopsy; one patient was classified as malignant on repeat biopsy and was diagnosed with papillary thyroid carcinoma. Eight were classified as a follicular lesions on repeat biopsy-six diagnosed as benign following lobectomy; two declined lobectomy and were followed radiologically with no nodule size increase. CONCLUSIONS: The false negative rate of an initial benign cytology result, from a thyroid nodule aspirate, is low. In the setting of an experienced multidisciplinary thyroid team, routine repeat aspiration is not justified
