Abstract Introduction Never events represent a huge cost burden to the NHS due to litigation. One such event occurred at a high-volume orthopaedic unit involving the wrong implant being inserted into a patient. An extensive investigation was undertaken which highlighted a combination of human error in the implant checking process and implant storage system. As a result, local guidance was developed to ensure a ‘prosthetic pause’ was performed prior to implant opening. Method An audit of implant checking practices was performed. The first cycle involved 14 cases observed over two weeks and the second involved 16 cases over five weeks. The checks were deemed compliant if the operating surgeon read aloud the implant details to the team, the scrub nurse did the same and both happened prior to implants being opened. Results The initial audit had 8 of 14 cases complying with local guidance. Following the addition of laminated copies of the guidance to all theatres, the guidance being re-distributed to staff and targeted education of the scrub team this improved to 13 of 16 cases. Conclusions Targeted interventions and the introduction of a ‘prosthetic pause’ resulted in an improvement in compliance with implant checks and reduces the risk of further never events.

Surgical procedures are intended to save lives and improve the quality of life, however omissions in essential practices (system and human error) contribute to unsafe surgical care, and cause significant harm to patients. For centuries it was believed that patients' co-morbidities and the surgeon's technical competence were the key determinants of surgical outcome; it is only within the last decade, that the relationship between failure to follow safety procedures, sub-optimal team work, poor communication and clinical outcomes has been appreciated (Vincent et al 2001). Recognition of the interdependencies for good surgical outcomes owes much to safety oriented research focusing on interpersonal behaviours and cognitive performance, the science of ‘human factors', and the route cause analysis (RCA) of surgical harm.

<p>Ever-increasing natural gas (NG) consumption trends due to its cleanest tag and abundant availability point towards an inevitable transition into an NG dominated economy. Solidified Natural Gas (SNG) storage via combustible ice or clathrate hydrates presents an economically sound prospect, promising high volume density, and long-term storage. Here we establish 1,3-dioxolane (DIOX), as a highly efficient dual-action (thermodynamic and kinetic promoter) additive for clathrate (methane sII) hydrate formation. By synergistically combining a small concentration (300 ppm) of kinetic promoter L-tryptophan with DIOX, we further demonstrate ultra-rapid hydrate formation with a methane uptake of 83.81 (±0.77) volume of gas/volume of hydrate (v/v) within 15 minutes. To the best of our knowledge, this is the fastest reaction time ever reported for sII hydrates related to SNG technology and represents a 147% increase in the hydrate formation rate compared to the standard water-DIOX system. Mixed methane-DIOX hydrates in pelletized form also exhibit incredible stability when stored at atmospheric pressure and moderate temperature of 268.15 K, thereby showcasing potential to be industrially adoptable for the development of a large-scale NG storage system.</p>

This case focuses on surgical site infections by asking the question: What is the incidence of clinically significant surgical site infections (CS-SSIs) following low- to moderate-risk ambulatory surgery in patients at low risk for surgical complications? This retrospective analysis found that the overall rate of CS-SSIs following ambulatory surgery is relatively low, at approximately 3.09 per 1,000 ambulatory surgical procedures. However, because of the high volume of ambulatory cases annually, the actual number of acute care visits due to CS-SSIs is large in aggregate. More than 90% of the CS-SSIs in this analysis required treatment in an inpatient setting, demonstrating a substantial cost burden. Thus, surgical site infections merit quality improvement efforts to minimize their occurrence.

835 Background: Current literature suggests surgeons and hospitals that perform large volumes of rectal cancer care achieve superior outcomes, but only about half of rectal cancer resections are performed by high-volume surgeons in comprehensive hospitals. Little is known about considerations of patients with rectal cancer when deciding where to receive surgery. Methods: A purposive sample of stage II/III rectal adenocarcinoma survivors diagnosed 2013-2015 were identified through the Iowa Cancer Registry and interviewed by telephone about factors influencing decisions on where to receive rectal cancer surgery. Interviews were recorded and transcribed, and a thematic analysis was conducted. Results: Thematic saturation was reached after interviewing 15 survivors. Mean age was 63; 60% were male, 53% resided in non-metropolitan areas and 60% received surgery at low-volume centers. Recommendation from a trusted source, usually a physician, appeared to be a main driver of where patients received surgery. Patients who chose high-volume centers were directed by a trusted source to seek care there, whereas patients who chose low-volume centers described valuing hospitals that were closer to home, knowing individuals at the hospital and receiving prior care there, and being familiar with others who received care from a specific surgeon. Most considered surgeon volume and experience to be important determinants of outcomes, but few actually assessed it. Most characterized surgeon experience based on subjective assessments including interpersonal skills, ability to explain procedures and perceived surgeon confidence. Several reported not trusting online sources for treatment information. Conclusions: Most rectal cancer patients in our sample relied on physician referrals to decide where to receive surgery. Further research is needed to determine rectal cancer patients’ preferences for obtaining information about surgeon/hospital volume and experience since our findings suggest they are neither discussing these factors with their surgeon nor researching them on their own. Once preferences are determined, targeted interventions facilitating more informed decision-making by patients can be developed.

The authors of the article emphasizes that the development of agro-industrial complex in our country is not only due to the formation of agricultural holdings, but also through the development of small business patterns. Taking into consideration the fact that large retail chains prefer to work with companies that can supply a high volume of goods at once, they are not interested in farmers who supply low volume of output. It is noted that the seasonal nature of agricultural output also increases the risk of product damage during storage. This risk is especially increased if the storage conditions are not met. It is found out that small-scale peasant business patterns are not able to maintain storage facilities that will meet different storage conditions for different types of products. Accordingly, for them, the problem of the risk of damage and loss of grown products due to non-compliance with storage conditions is more acute. The situation under consideration determines the relevance of the stated topic. The purpose of the study is to clarify the main goals and objectives of the formation of a modern storage system for agricultural products as the main factor in reducing the risk of its damage and loss. The study was conducted in several stages: the institutional framework for the formation of storage systems for agricultural products was studied; the institutional structure of the Central Federal district to create a modern system for storing agricultural raw materials and goods was systematized; target installations for placement of agricultural products storage enterprises in the context of the Central Federal district regions have been defined.

Abstract Reduction of the patient’s received radiation dose to as low as reasonably achievable (ALARA) is based on recommendations of radiation protection organizations such as the International Commission on Radiological Protection (ICRP) and the National Radiological Protection Board (NRPB). The aim of this study was to explore the frequency and characteristics of rejected / repeated radiographic films in governmental and private centers in Jenin city. The radiological centers were chosen based on their high volume of radiographic studies. The evaluation was carried out over a period of four months. The collected data were compiled at the end of each week and entered into a computer for analysis at the end of study. Overall 5000 films (images) were performed in four months, The average repeat rate of radiographic images was 10% (500 films). Repetition rate was the same for both thoracic and abdominal images (42%). The main reason for repeating imaging was inadequate imaging quality (58.2%) and poor film processing (38%). Human error was the most likely reason necessitating the repetition of the radiographs (48 %). Infant and children groups comprised 85% of the patient population that required repetition of the radiographic studies. In conclusion, we have a higher repetition rate of imaging studies compared to the international standards (10% vs. 4-6%, respectively). This is especially noticeable in infants and children, and mainly attributed to human error in obtaining and processing images. This is an important issue that needs to be addressed on a national level due to the ill effects associated with excessive exposure to radiation especially in children, and to reduce cost of the care delivered.

Abstract In this study, a mechanical model was applied in order to replicate potential surgical fire conditions in an oxygen-enriched environment with and without high-volume suction typical for dental surgical applications. During 41 trials, 3 combustion events were measured: an audible pop, a visible flash of light, and full ignition. In at least 11 of 21 trials without suction, all 3 conditions were observed, sometimes with an extent of fire that required early termination of the experimental trial. By contrast, in 18 of 20 with-suction trials, ignition did not occur at all, and in the 2 cases where ignition did occur, the fire was qualitatively a much smaller, candle-like flame. Statistically comparing these 3 combustion events in the no-suction versus with-suction trials, ignition (P = .0005), audible pop (P = .0211), and flash (P = .0092) were all significantly more likely in the no-suction condition. These results suggest a possible significant and new element to be added to existing surgical fire safety protocols toward making surgical fires the “never-events” they should be.

A systematic study has been made of the effects of various heat treatments on the microstructures of several experimental high volume fraction γ’ precipitation hardened nickel-base alloys, after doping with ∼2 w/o Hf so as to improve the stress rupture life and ductility. The most significant microstructural chan§e brought about by prolonged aging at temperatures in the range 1600°-1900°F was the decoration of grain boundaries with precipitate particles.Precipitation along the grain boundaries was first detected by optical microscopy, but it was necessary to use the scanning electron microscope to reveal the details of the precipitate morphology. Figure 1(a) shows the grain boundary precipitates in relief, after partial dissolution of the surrounding γ + γ’ matrix.

A color coded digital image processing is accomplished by using JEM100CX TEM SCAN and ORTEC’s LSI-11 computer based multi-channel analyzer (EEDS-II-System III) for image analysis and display. Color coding of the recorded image enables enhanced visualization of the image using mathematical techniques such as compression, gray scale expansion, gamma-processing, filtering, etc., without subjecting the sample to further electron beam irradiation once images have been stored in the memory.The powerful combination between a scanning electron microscope and computer is starting to be widely used 1) - 4) for the purpose of image processing and particle analysis. Especially, in scanning electron microscopy it is possible to get all information resulting from the interactions between the electron beam and specimen materials, by using different detectors for signals such as secondary electron, backscattered electrons, elastic scattered electrons, inelastic scattered electrons, un-scattered electrons, X-rays, etc., each of which contains specific information arising from their physical origin, study of a wide range of effects becomes possible.
