Clinical utility of plain-film abdominal radiographs for inpatients outside standard working hours in a large university teaching hospital.

INTRODUCTION: Plain film abdominal radiographs (PFAs) are frequently the initial investigation ordered for patients with abdominal symptoms. However, increasing use of emergency ultrasound and availability of emergency CT raises the question of whether PFA remains an appropriate first line investigation. We investigated the impact of out of hours (OOH) PFAs on inpatient management. METHODS: All consecutive PFAs over an 8-week period were included to determine the impact on patient management. OOH was classified as from 5pm to 9am Monday to Friday, weekends and bank-holidays. PACS and hospital records were accessed to determine patient pathways. The institution is a tertiary referral centre with 850 acute beds and serves a population of 950,000. RESULTS: A total of 758 consecutive PFAs were performed in total (58.3% male, mean age 58.1 (range 0-93)). 310 (40.9%) were requested from the emergency department (ED) and 382 (50.4%) were requested from wards. 160 (21.1%) met the criteria of OOH, of these 120 (72.2%) were from ED and 28 were on adult inpatients. Of these 28, none had a change in management based on the PFA result. CONCLUSION: Our study suggests that OOH PFAs of inpatients are of limited clinical utility. These patients are exposed to extra radiation. IMPLICATIONS FOR PRACTICE: We propose that OOH PFAs of inpatients should be questioned as a viable investigation due to the limited contribution they offer in managing patients, the deleterious effects they confer on the patient and the associated economic cost. Further studies are needed to assess if these results are generalizable to other large hospitals.

Super-resolution radar imaging for breast cancer detection with microwaves: the integrated information selection criteria.

This paper focuses on the data preprocessing scheme, as well as on the frequency selection and spatial filtering modules integrated with a Time-Reversal Multiple Signal Classification (TR-MUSIC) algorithm, for microwave breast imaging. This algorithm is part of the data processing chain of the Wavelia Microwave Breast Imaging (MBI) system prototype, which has been recently installed at the University Hospital of Galway, Ireland, for a first-in-human clinical trial. Indicative results from application of the algorithm on an experimental phantom dataset, and on a first patient dataset, are presented in this paper. Good correspondence between the two datasets is demonstrated, confirming the validity of the experimental setup used so far for the on-site acceptance of the Wavelia system, after installation at the hospital for clinical testing.

Undergraduate basic surgical skills education: impact on attitudes to a career in surgery and surgical skills acquisition.

INTRODUCTION: Basic surgical skills modules in medical education are effective in teaching skills and increasing confidence among students approaching surgery. However, these modules are not delivered universally and their effect on the professional development of graduates has not been established. We aimed to assess the impact of a 10-week basic surgical skills module on attitudes and technical skills of first year medical students compared to interns. METHODS: Eighteen students participated and were assessed using a 4-part questionnaire. Technical skills were assessed by observing students perform a basic interrupted suture, using the objective structured assessment of technical skills (OSATS) tool. Fourteen interns were recruited. RESULTS: Students were more confident in surgical scrubbing (mean score 4.0 vs. 2.86, p = 0.001), and performing a basic suture (4.05 vs. 1.93, p = 0.000), more enthusiastic about assisting with an operation (4.5 vs. 3.0, p = 0.001) and more likely to consider a career in surgery (4.16 vs. 2.28, p = 0.000). Technical skills were greater in the student group (mean score 30.8 vs. 19.6, p = 0.001). Five interns had taken part in surgical skills modules as undergraduates. Their technical skills were significantly higher compared to interns who had not (n = 9) (28.8 vs. 14.5, p = 0.006), and they were more likely to consider a career in surgery (3.6 vs. 1.5, p = 0.036). CONCLUSION: The introduction of surgical skills teaching to the undergraduate medical curriculum has a positive impact on students' attitudes towards surgery and accelerates basic technical skills development. Consideration should be given to development of a standardised undergraduate core curriculum in basic surgical skills teaching.

The role of laparoscopic sleeve gastrectomy as a treatment for morbid obesity; review of outcomes.

BACKGROUND: Global prevalence of obesity has soared. Where lifestyle and medical treatments have failed, laparoscopic sleeve gastrectomy (LSG) is increasingly regarded as a good surgical procedure for morbid obesity. Following the introduction of LSG, we assessed our surgical outcomes. METHODS: We reviewed a consecutive series of LSGs from January 2009 to January 2015. Our primary focus was to assess the success of this procedure on the percentage excess body weight loss (%EWL), Body Mass Index (BMI), hypertension and diabetes. Additionally, we evaluated the rate of procedure-related complications. RESULTS: There were 183 consecutive patients evaluated. Median age was 45 years (24-73). The majority were female (73.2 %, n = 134). At 1 year post-op, median %EWL was 57.6 %. There was an associated median reduction in BMI of 16 kg/m2 (0-33). At 2 years, median %EWL was sustained at 58.4 %. The median reduction in BMI was 16 kg/m2 (4-32). At 2-year post-op, 78.9 % of diabetic patients had their diabetic medications completely discontinued, while a further 15.8 % having their medication reduced. 34.6 % of hypertensive patients had their antihypertensives discontinued, with 50 % having medications reduced. There was no procedure related mortality. 3.3 % (n = 6) of patients had a confirmed staple-line leak. CONCLUSION: This study shows LSG is a safe and successful management strategy for morbid obesity. In addition to the direct effects of sustained weight loss, it highlights indirect effects that LSG has on obesity-related health issues, with substantial reduction in diabetic and anti-hypertensive medications. Our results reaffirm international studies of the beneficial effects of LSG on Type II diabetes and hypertension.
