Health utility after emergency medical admission: a cross-sectional survey

Objectives: Health utility combines health related quality of life and mortality to produce a generic outcome measure reflecting both morbidity and mortality. It has not been widely used as an outcome measure in evaluations of emergency care and little is known about the feasibility of measurement, typical values obtained or baseline factors that predict health utility. We aimed to measure health utility after emergency medical admission, to compare health utility to age, gender and regional population norms, and identify independent predictors of health utility. Methods: We selected 5760 patients across three hospitals who were admitted to hospital by ambulance as a medical emergency. The EQ-5D questionnaire was mailed to all who were still alive 30 days after admission. Health utility was estimated by applying tariff values to the EQ-5D responses or imputing a value of zero for those who had died. Multivariable analysis was used to identify independent predictors of health utility at 30 days. Results: Responses were received from 2488 (47.7%) patients, while 541 (9.4%) had died. Most respondents reported some or severe problems with each aspect of health. Mean health utility was 0.49 (standard deviation 0.35) in survivors and 0.45 (0.36) including non-survivors. Some 75% had health utility below their expected value (mean loss 0.32, 95% confidence interval 0.31 to 0.33) and 11% had health utility below zero (worse than death). On multivariable modelling, reduced health utility was associated with increased age and lower GCS, varied according to ICD10 code and was lower among females, patients with recent hospital admission, steroid therapy, or history of chronic respiratory disease, malignancy, diabetes or epilepsy. Conclusions: Health utility can be measured after emergency medical admission, although responder bias may be significant. Health utility after emergency medical admission is poor compared to population norms. We have identified independent predictors or health utility that need to be measured and taken into account in nonrandomized evaluations of emergency care

Smart clothing for falls protection and detection: User-centred co-design and feasibility study

The prevalence and impact of hip fractures on the health and wealth of nations is a global problem and source of health inequalities. This paper reports on the co-design and feasibility testing of a new range of protective, smart clothing. The feasibility of research in a population of older adults in supported living is explored, as are the conceptualisation and measurement of adherence

Salary, Promotion, and Tenure Status of Minority and Women Faculty in U.S. Colleges and Universities

This report examines differences among postsecondary faculty members by gender and by race/ethnicity. Comparisons were made on several human capital (e.g., education and experience) and structural (e.g., academic discipline and institution type) variables as well as faculty outcomes (salary, tenure, and rank). A multivariate analysis of factors associated with salary was also conducted. Male faculty in this group were compared to female faculty, and comparisons were also made among four racial/ethnic groups: black, non-Hispanic; white, non- Hispanic; Hispanic; and Asian/Pacific Islander. Generated from the 1992-93 National Study of Postsecondary Faculty (NSOPF:93), the analyses presented in this report are based on U.S. citizens with faculty status at 2- and 4-year (and above) institutions who indicated that their primary activity in the fall of 1992 was teaching. Most analyses were also restricted to full-time faculty members. NSOPF:93 is the second in a series of surveys on faculty conducted by the U.S. Department of Education, National Center for Education Statistics

State of the Humanities 2021: Workforce & Beyond

How should one measure the value of a college degree? In recent years, policy-makers have focused their attention on earnings as the primary measure of the value of a degree, often using that metric to single out humanities degrees as less valuable than others. But there are other—less tangible—measures of value, such as satisfaction with one's work and life more generally, that might also be applied to these discussions.Without taking a position on which metrics are best, this report, based largely on original research commissioned by the American Academy of Arts and Sciences' Humanities Indicators, examines a variety of outcome measures, including graduates' satisfaction with their jobs, their finances, and their lives generally. The evidence shows that humanities graduates tend to earn less and have slightly higher levels of unemployment than business majors and graduates from some STEM fields. With respect to perceived well-being, however, humanities majors are similar to graduates from almost every other field. The data cannot explain the seeming disparity between the objective and subjective measures, but they provide a starting point for a more nuanced discussion about the relationship among fields of undergraduate study, employment, and quality of life. And for faculty, the report also points to a potential area of concern regarding the way they communicate to students about the skills developed in the course of an education in the field, as a substantial share of humanities graduates perceive little or no relationship between their job and their degree. The data were all gathered prior to the COVID-19 pandemic, but past experience tracking this sort of data for the humanities—particularly through the Great Recession—gives us little reason to expect a significant shift in values over the medium term

The rate of brain abnormalities on in utero MRI studies in fetuses with normal ultrasound examinations of the brain and calculation of indicators of diagnostic performance

AIM To estimate the rate of unexpected brain abnormalities detected by in utero magnetic resonance imaging (iuMRI) in fetuses without abnormalities at ultrasonography (USS). MATERIALS AND METHODS A prospective cohort study of pregnant women whose fetus had no structural brain (or body) abnormalities recognised on antenatal ultrasonography. Women were recruited from 12 centres across the UK and underwent iuMRI at 18 gestational weeks or more in the [blinded for review]. The imaging studies were reviewed by an experienced neuroradiologist. The positive and negative predictive values of both USS and iuMRI have been calculated by combining the results of this study with the results from the main [blinded for review] study. RESULTS One hundred and ninety-eight pregnant women were recruited and underwent iuMRI of 205 fetuses. Brain abnormalities were shown on iuMRI in two fetuses that were not recognised on USS (one case of a focal cortical abnormality and one case of mild ventriculomegaly). The negative predictive value for USS was 99.5% and 100% for iuMRI. CONCLUSIONS To the authors' knowledge, this is the first study comparing USS and iuMRI in low-risk pregnancies. USS has a comparatively high rule-out for fetal brain abnormalities and should remain the screening tool of choice

State of the Humanities 2022: From Graduate Education to the Workforce

Given the recent decline in students earning bachelor's degrees in the humanities, a great deal of concern is focused on undergraduate education. But many of the questions received by the Humanities Indicators staff have to do with outcomes for those who earn a graduate degree in the field. This report explores several key topics related to graduate education, including degree trends, the demographics of degree recipients, the extent to which programs engage students in career preparation activities, and graduates' career outcomes. The report relies heavily on the high-quality data collected by the U.S. Department of Education's National Center for Education Statistics, and also the National Science Foundation's National Center for Science and Engineering Statistics, several of whose surveys yield valuable information about graduate degree holders in the humanities.The findings include a few surprises: 1) while most of the attention in the disciplines seems to focus on PhDs, the field conferred almost five times as many master's as doctoral degrees in recent years; 2) even so, the number of master's degrees conferred annually in the humanities has been in decline over the past several years and their share of all master's and professional degrees reached a historic low in 2020; 3) the number of humanities PhDs awarded each year was at a near-record high in 2020, but as a share of all doctoral degrees, they fell to a historic low; 4) while the academic job market for humanities PhDs has been depressed since 2008, there is no evidence that this is due to the substitution of adjunct for tenure-track positions; and 5) regardless of where they end up—either in academia or out—the large majority of graduate degree recipients in the humanities are satisfied with their jobs, despite earnings that are considerably lower than those of their counterparts from other fields.This report reflects the ongoing mission of the Humanities Indicators, a nationally recognized source of nonpartisan information about the field. The Indicators website covers 121 topics and includes more than 340 graphs detailing the state of the humanities in schools, higher education, and the workforce; levels of support for research and other key activities; and the role of the humanities in the day-to-day life of the nation. The project draws on data sources that meet the highest standards of social scientific rigor, relying heavily on the products of the U.S. federal statistical system

Atrial fibrillation after gastrointestinal surgery: incidence and associated risk factors

BACKGROUND: Atrial fibrillation (AF) is a common dysrhythmia that can occur after major physiological stress including surgery (postoperative AF). There are few data on postoperative AF after abdominal surgery. We set out to define the incidence of de novo postoperative AF after abdominal surgery and associated risk factors. METHODS: The Patient History Integrated Data store administrative database was interrogated for patients aged ≥65 y undergoing abdominal surgery from April 2012 to April 2014. Patients with pre-existing AF were excluded. The primary outcome was diagnosis of AF. RESULTS: Two thousand nine hundred and sixty-seven cases were included of whom 187 developed postoperative AF within 90 d (6.3%). The rate of postoperative AF varied by operation and was highest in small bowel resection (17.2%) and lowest in biliary surgery (4.8%). Median time to detection of postoperative AF was 32 d. Patients who developed postoperative AF were significantly older than those who did not develop AF (median age 75.3 y versus 72.4 y, P < 0.01). Logistic regression modeling found increasing age (odds ratio [OR] 1.03 [confidence interval {CI} 1.01-1.06], hypertension OR 1.73 [CI 1.19-2.51]), congestive cardiac failure (OR 3.04 [CI 1.88-4.92], and vascular disease OR 2.29 [CI 1.39-3.37]) were predictive of the development of postoperative AF within 30 d. The area under the curve for this model was 0.733. CONCLUSIONS: Postoperative AF affects a significant number of patients after abdominal surgery. Demographics such as history of cardiovascular disease might aid prediction of postoperative AF. Postoperative AF is mostly identified after discharge, suggesting the need for postoperative screening

A survey of castration methods and associated livestock management practices performed by bovine veterinarians in the United States

<p>Abstract</p> <p>Background</p> <p>Castration of male calves destined for beef production is a common management practice performed in the United States amounting to approximately 15 million procedures per year. Societal concern about the moral and ethical treatment of animals is increasing. Therefore, production agriculture is faced with the challenge of formulating animal welfare policies relating to routine management practices such as castration. To enable the livestock industry to effectively respond to these challenges there is a need for more data on management practices that are commonly used in cattle production systems. The objective of this survey was to describe castration methods, adverse events and husbandry procedures performed by U.S. veterinarians at the time of castration. Invitations to participate in the survey were sent to email addresses of 1,669 members of the American Association of Bovine Practitioners and 303 members of the Academy of Veterinary Consultants.</p> <p>Results</p> <p>After partially completed surveys and missing data were omitted, 189 responses were included in the analysis. Surgical castration with a scalpel followed by testicular removal by twisting (calves <90 kg) or an emasculator (calves >90 kg) was the most common method of castration used. The potential risk of injury to the operator, size of the calf, handling facilities and experience with the technique were the most important considerations used to determine the method of castration used. Swelling, stiffness and increased lying time were the most prevalent adverse events observed following castration. One in five practitioners report using an analgesic or local anesthetic at the time of castration. Approximately 90% of respondents indicated that they vaccinate and dehorn calves at the time of castration. Over half the respondents use disinfectants, prophylactic antimicrobials and tetanus toxoid to reduce complications following castration.</p> <p>Conclusions</p> <p>The results of this survey describe current methods of castration and associated management practices employed by bovine veterinarians in the U.S. Such data are needed to guide future animal well-being research, the outcomes of which can be used to develop industry-relevant welfare guidelines.</p

UK-based, multisite, prospective cohort study of small bowel obstruction in acute surgical services: National Audit of Small Bowel Obstruction (NASBO) protocol

Introduction Small bowel obstruction (SBO) is a common indication for emergency laparotomy in the UK, which is associated with a 90-day mortality rate of 13%. There are currently no UK clinical guidelines for the management of this condition. The aim of this multicentre prospective cohort study is to describe the burden, variation in management and associated outcomes of SBO in the UK adult population. Methods and analysis UK hospitals providing emergency general surgery are eligible to participate. This study has three components: (1) a clinical preference questionnaire to be completed by consultants providing emergency general surgical care to assesses preferences in diagnostics and therapeutic approaches, including laparoscopy and nutritional interventions; (2) site resource profile questionnaire to indicate ease of access to diagnostic services, operating theatres, nutritional support teams and postoperative support including intensive care; (3) prospective cohort study of all cases of SBO admitted during an 8-week period at participating trusts. Data on diagnostics, operative and nutritional interventions, and in-hospital mortality and morbidity will be captured, followed by data validation. Ethics and dissemination This will be conducted as a national audit of practice in conjunction with trainee research collaboratives, with support from patient representatives, surgeons, anaesthetists, gastroenterologists and a clinical trials unit. Site-specific reports will be provided to each participant site as well as an overall report to be disseminated through specialist societies. Results will be published in a formal project report endorsed by stakeholders, and in peer-reviewed scientific reports. Key findings will be debated at a focused national meeting with a view to quality improvement initiatives
