Assessing human germ-cell mutagenesis in the Postgenome Era: A celebration of the legacy of William Lawson (Bill) Russell,

ENVIRONMENTAL AND MOLECULAR MUTAGENESIS, Issue 2 2007
Andrew J. Wyrobek
Abstract Birth defects, de novo genetic diseases, and chromosomal abnormality syndromes occur in ,5% of all live births, and affected children suffer from a broad range of lifelong health consequences. Despite the social and medical impact of these defects, and the 8 decades of research in animal systems that have identified numerous germ-cell mutagens, no human germ-cell mutagen has been confirmed to date. There is now a growing consensus that the inability to detect human germ-cell mutagens is due to technological limitations in the detection of random mutations rather than biological differences between animal and human susceptibility. A multidisciplinary workshop responding to this challenge convened at The Jackson Laboratory in Bar Harbor, Maine. The purpose of the workshop was to assess the applicability of an emerging repertoire of genomic technologies to studies of human germ-cell mutagenesis. Workshop participants recommended large-scale human germ-cell mutation studies be conducted using samples from donors with high-dose exposures, such as cancer survivors. Within this high-risk cohort, parents and children could be evaluated for heritable changes in (a) DNA sequence and chromosomal structure, (b) repeat sequences and minisatellites, and (c) global gene expression profiles and pathways. Participants also advocated the establishment of a bio-bank of human tissue samples from donors with well-characterized exposure, including medical and reproductive histories. This mutational resource could support large-scale, multiple-endpoint studies. Additional studies could involve the examination of transgenerational effects associated with changes in imprinting and methylation patterns, nucleotide repeats, and mitochondrial DNA mutations. The further development of animal models and the integration of these with human studies are necessary to provide molecular insights into the mechanisms of germ-cell mutations and to identify prevention strategies. Furthermore, scientific specialty groups should be convened to review and prioritize the evidence for germ-cell mutagenicity from common environmental, occupational, medical, and lifestyle exposures. Workshop attendees agreed on the need for a full-scale assault to address key fundamental questions in human germ-cell environmental mutagenesis. These include, but are not limited to, the following: Do human germ-cell mutagens exist? What are the risks to future generations? Are some parents at higher risk than others for acquiring and transmitting germ-cell mutations? Obtaining answers to these, and other critical questions, will require strong support from relevant funding agencies, in addition to the engagement of scientists outside the fields of genomics and germ-cell mutagenesis.

An Epidemiologic Study of Closed Emergency Department Malpractice Claims in a National Database of Physician Malpractice Insurers

ACADEMIC EMERGENCY MEDICINE, Issue 5 2010
Terrence W. Brown MD
Abstract Objectives:, The objective was to perform an epidemiologic study of emergency department (ED) medical malpractice claims using data maintained by the Physician Insurers Association of America (PIAA), a trade association whose participating malpractice insurance carriers collectively insure over 60% of practicing physicians in the United States. Methods:, All closed malpractice claims in the PIAA database between 1985 and 2007, where an event in an ED was alleged to have caused injury to a patient 18 years of age or older, were retrospectively reviewed. Study outcomes were the frequency of claims and average indemnity payments associated with specific errors identified by the malpractice insurer, as well as associated health conditions, primary specialty groups, and injury severity. Indemnity payments include money paid to claimants as a result of settlement or court adjudication, and this financial obligation to compensate a claimant constitutes the insured's financial liability. These payments do not include the expenses associated with resolving a claim, such as attorneys' fees. The study examined claims by adjudicatory outcome, associated financial liability, and expenses of litigation. Adjudicatory outcome refers to the legal disposition of a claim as it makes its way into and through the court system and includes resolution of claims by formal verdict as well as by settlement. The study also investigated how the number of claims, average indemnity payments, paid-to-close ratios (the percentage of closed claims that resolved with a payment to the plaintiff), and litigation expenses have trended over the 23-year study period. Results:, The authors identified 11,529 claims arising from an event originating in an ED, representing over $664 million in total liability over the 23-year study period. Emergency physicians (EPs) were the primary defendants in 19% of ED claims. The largest sources of error, as identified by the individual malpractice insurer, included errors in diagnosis (37%), followed by improper performance of a procedure (17%). In 18% of claims, no error could be identified by the insurer. Acute myocardial infarction (AMI; 5%), fractures (6%), and appendicitis (2%) were the health conditions associated with the highest number of claims. Over two-thirds of claims (70%) closed without payment to the claimant. Most claims that paid out did so through settlement (29%). Only 7% of claims were resolved by verdict, and 85% of those were in favor of the clinician. Over time, the average indemnity payments and expenses of litigation, adjusted for inflation, more than doubled, while both the total number of claims and number of paid claims decreased. Conclusions:, Emergency physicians were the primary defendants in a relatively small proportion of ED claims. The disease processes associated with the highest numbers of claims included AMI, appendicitis, and fractures. The largest share of overall indemnity was attributed to errors in the diagnostic process. The financial liability of medical malpractice in the ED is substantial, yet the vast majority of claims resolve in favor of the clinician. Efforts to mitigate risk in the ED should include the diverse clinical specialties who work in this complex environment, with attention to those health conditions and potential errors with the highest risk.

Scope and scale inefficiencies in physician practices,

HEALTH ECONOMICS, Issue 11 2004
Robert Rosenman
Abstract Using a national data set, this paper looks at the efficiency of physician practices, focusing on scopes of service by comparing single specialty groups and multispecialty groups. An analysis of efficiency using DEA indicates that there are scope inefficiencies from combining different types of providers into a single practice. Most of the inefficiency is due to technical rather than allocative reasons. In addition, we find that larger practices are able to capture efficiencies of scope, but incur inefficiencies of scale.

A comparison study on nurses' and therapists' perception on the positioning of stroke patients in Singapore General Hospital

INTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 4 2007
Lilian Yew Siew Mee Adv.
Before developing a study to evaluate the effect of positioning on outcome after stroke, it was important to explore whether there were differences in perception between neurology/neurosurgery nurses, nurses from other wards, occupational therapists (OTs) and physiotherapists (PTs) over the positioning of stroke patients in Singapore General Hospital (SGH). Questionnaires were sent to 227 nurses, seven PTs and six OTs from six wards where more stroke patients are cared for in SGH. Seventy-two per cent of the respondents identified bed positioning as their positioning strategy. ,Sitting in a chair' was selected as the best position by most of the respondents in the three specialty groups for nursing conscious hemiplegic stroke patients. ,A 30 degree propped-up angle in bed' was selected as the best position by the majority of the nurses from the neuroscience wards while ,lying horizontally on the unaffected side' of the body was selected as the best position by most of the nurses from other wards, PTs and OTs for nursing unconscious hemiplegic stroke patients. However, no significant difference was found between the groups in what they considered the best position for stroke patients. The lack of consensus between these respondents is probably because there are few studies to guide nursing practices for the positioning of stroke patients. Hence, research to confirm which positions improve or hinder outcome after stroke is indispensable. [source]


Specialty care and education associated with greater disease-specific knowledge but not satisfaction with care for chronic hepatitis C

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2009
L. A. BESTE
Summary Background, Little is known about differences among hepatitis C virus (HCV) patients managed by generalists vs. specialists with respect to patient-centred outcomes, such as disease-specific knowledge, health-related quality of life (HRQoL) and satisfaction with care. Aim, To examine selected patient-centred outcomes of HCV-related care provided in primary care, specialty care or both. Methods, A total of 629 chronic HCV patients completed a survey including an HCV knowledge assessment and validated instruments for satisfaction and HRQoL. Multivariable linear regression was used to compare outcomes between groups. Results, Adjusted total HCV knowledge score was lower among patients who did not attend specialty care (P < 0.01). Primary care and specialty patients did not differ in adjusted general HRQoL or satisfaction. Sixty percent of specialty patients underwent formal HCV education, which was associated with 5% higher knowledge score (P = 0.01). General HRQoL and patient satisfaction did not differ between primary care and specialty groups. Disease-specific knowledge and care satisfaction were independent of mental illness, substance abuse, socio-economic variables, history of antiviral treatment, formal HCV education and duration of time between last visit and survey completion. Conclusions, Primary care patients with chronic HCV have lower adjusted disease-specific knowledge than specialty patients, but no difference in general HRQoL or patient satisfaction. [source]


EARLY EXPERIENCE WITH CLINICAL INDICATORS IN SURGERY

ANZ JOURNAL OF SURGERY, Issue 6 2000
B. T. Collopy
Background: In 1997 a set of 53 clinical indicators developed by the Royal Australasian College of Surgeons (RACS) and the Australian Council on Healthcare Standards (ACHS) Care Evaluation Programme (CEP), was introduced into the ACHS Evaluation and Quality Improvement Programme (EQuIP). The clinical indicators covered 20 different conditions or procedures for eight specialty groups and were designed to act as flags to possible problems in surgical care. Methods: The development process took several years and included a literature review, field testing, and revision of the indicators prior to approval by the College council. In their first year 155 health-care organizations (HCO) addressed the indicators and this rose to 210 in 1998. Data were received from all states and both public and private facilities. Results: The collected data for 1997 and 1998 for some of the indicators revealed rates which were comparable with those reported in the international literature. For example, the rates of bile duct injury in laparoscopic cholecystectomy were 0.7 and 0.53%, respectively; the mortality rates for coronary artery graft surgery were 2.5 and 2.1%, respectively; the mortality rates after elective abdominal aortic aneurysm repair were 2.5 and 3.7%, respectively; and the post-tonsillectomy reactionary haemorrhage rates were 0.9 and 1.3%, respectively. Results for some indicators differed appreciably from other reports, flagging the need for further investigation; for example, the negative histology rates for appendectomy in children were 18.6 and 21.2%, respectively, and the rates for completeness of excision of malignant skin tumours were 90.7 and 90%, respectively. The significance of these figures, however, depends upon validation of the data and their reliability and reproducibility. Because reliability can be finally determined only at the hospital level they are of limited value for broader comparison. Conclusion: The process of review established for the indicator set has led to refinement of some indicators through improvement of definitions, and to a considerable reduction in the number of indicators to 29 (covering 18 procedures), for the second version of the indicators (which was introduced for use from January 1999). The clinical indicator programme, as it has with other disciplines, hopefully will provide a stimulus to the modification and improvement of surgical practice. Clinician ownership should enhance the collection of reliable data and hence their usefulness. [source]


Emergency Medicine Career Choice: A Profile of Factors and Influences from the Association of American Medical Colleges (AAMC) Graduation Questionnaires

ACADEMIC EMERGENCY MEDICINE, Issue 6 2009
Jeremy S. Boyd
Abstract Objectives:, This study sought to account for trends in medical student specialty choice by examining the importance of lifestyle factors. Emergency medicine (EM) is among several medical specialties classified as having a "controllable lifestyle." The primary objective of this study was to determine if medical students choosing careers in EM have a different profile of influences, values, and expectations from students choosing other specialties or specialty groups. Of secondary interest was how much lifestyle influenced students choosing EM compared to students choosing controllable lifestyle (CL) specialties. Methods:, Using data from the 2005 and 2006 Association of American Medical Colleges (AAMC) graduation questionnaire (GQ) supplemental surveys, we grouped responses according to desired specialty choice: EM (n = 963), CL (n = 3,681), primary care (PC; n = 3,191), or surgical specialty (SS; n = 1,694). The survey requires students to rate the influence of nine specific factors in determining their specialty choice: lifestyle, competitiveness, high level of educational debt, mentors and role models, options for fellowship training, salary expectations, length of residency training, family expectations, and medical school career planning activities. Using one-way analysis of variance (ANOVA) and nonparametric statistics, we assessed responses among the four subgroups for differences in the importance attributed to these factors. Results:, A total of 13,440 students completed the two supplemental surveys of the GQ. Of these students, 9,529 identified a specialty choice that fell within one of the four comparison groups and were included in the analysis. Compared to other specialty groups, students choosing EM reported lifestyle and length of residency as strong influences, while attributing less influence to mentors and options for fellowship training. Conclusions:, Students choosing a career in EM have distinctly different priorities and influences than students entering PC and SS. The profile of students who choose EM is very similar to those choosing traditional CL specialties. A more thorough understanding of the values and priorities that shape medical student career selection may allow educators to provide better career counseling. [source]


THE DEATH OF BIOETHICS (AS WE ONCE KNEW IT)

BIOETHICS, Issue 5 2010
RUTH MACKLIN
ABSTRACT Fast forward 50 years into the future. A look back at what occurred in the field of bioethics since 2010 reveals that a conference in 2050 commemorated the death of bioethics. In a steady progression over the years, the field became increasingly fragmented and bureaucratized. Disagreement and dissension were rife, and this once flourishing, multidisciplinary field began to splinter in multiple ways. Prominent journals folded, one by one, and were replaced with specialized publications dealing with genethics, reproethics, nanoethics, and necroethics. Mainstream bioethics organizations also collapsed, giving way to new associations along disciplinary and sub-disciplinary lines. Physicians established their own journals, and specialty groups broke away from more general associations of medical ethics. Lawyers also split into three separate factions, and philosophers rejected all but the most rigorous, analytic articles into their newly established journal. Matters finally came to a head with global warming, the world-wide spread of malaria and dengue, and the cost of medical treatments out of reach for almost everyone. The result was the need to develop plans for strict rationing of medical care. At the same time, recognition emerged of the importance of the right to health and the need for global justice in health. By 2060, a spark of hope was ignited, opening the door to the resuscitation of bioethics and involvement of the global community. [source]
