Hospital reform and nursing labor market trends in Canada.

OBJECTIVES: Trends in the Canadian registered nurse (RN) workforce during the past 3 decades are examined, and the implications of current hospital sector retrenchment for RN employment are considered. METHODS: A descriptive review using relevant literature and existing databases on the nurse workforce is presented. RESULTS: From the 1960s through the 1980s, the Canadian RN workforce grew exponentially, fueled by expansions in the health-care delivery system under Medicare, rising inpatient acuity and skill-intensive patient care, enhanced access to nursing education, and increases in the numbers of women entering the workforce. Acute care hospitals have and continue to be the predominant employer of RNs. However, the 1990s have witnessed considerable hospital retrenchment, and with that retrenchment the growth of the hospital RN workforce has slowed dramatically. CONCLUSIONS: The ultimate outcomes of hospital retrenchment for the RN workforce remain unclear. Some speculate that the quality of care and working conditions will deteriorate in hospitals, as hospital administrators replace RN staff with lesser trained personnel to reduce costs. Others see change in the hospital sector as an opportunity for RNs to expand their scope of practice and responsibility in outpatient settings. The need for national and international research on the outcomes of hospital restructuring on patient care and the work of RNs is critical to sound policy making.

The impact of risk information on patients' willingness to pay for autologous blood donation.

OBJECTIVES: For contingent valuation to provide valid values for policy making, it is important that respondents be well informed about the goods they are asked to value. Few studies, however, have tested the impact of providing this information This study assessed the impact of risk information on patients' willingness to pay for autologous blood donation and derived the willingness to pay in a sample of informed patients. METHODS: Patients were randomized either to receive information about the risks of complications from allogeneic (volunteer) blood transfusions or to base their willingness to pay responses on their own prior knowledge. Four hundred twelve autologous blood donors were recruited from three study sites. Self-administered questionnaires collected information on willingness to pay, risk perceptions, and socioeconomic information. RESULTS: As predicted by our theoretical model, providing risk information reduced the variance in the willingness to pay for autologous blood donation. A tendency for information to reduce the willingness to pay was also found, suggesting that uninformed patients, on average, overestimate the risks of allogeneic blood transfusions. The median willingness to pay in the informed sample was approximately $750 to $1,100, depending on the estimation method, compared with $800 to $1,900 in the uninformed group. Willingness to pay was significantly related to perceived transfusion risk, personal income, and dread of transfusions. CONCLUSIONS: Our results are consistent with an economic model where individuals update their prior risk perceptions with new information. The willingness to pay in the informed sample was far higher than the costs of autologous blood donation, suggesting that total benefits outweigh the costs of the procedure.

Parenting preterm infants: a meta-synthesis.

PURPOSE: To synthesize the findings of qualitative studies on parenting preterm infants and present a framework that will enable clinical nurses to provide better care. STUDY DESIGN AND METHODS: A meta-ethnographic approach was used to synthesize the findings of 10 qualitative research studies that focused on parenting the preterm infant upon hospital discharge and on into the toddler years. RESULTS: Five themes of parenting preterm infants emerged: adapting to risk, protecting fragility, preserving the family, compensating for the past, and cautiously affirming the future. CLINICAL IMPLICATIONS: Nurses provide expert care, anticipatory guidance, and education for NICU babies and families, but should also foster the inclusion of all family members in the NICU setting, provide opportunities for parental peer support, establish effective systems of continuity of care, and advocate for parents of preterms in policy-making arenas.

Measuring physical activity with the behavioral risk factor surveillance system.

PURPOSE AND METHODS: Because regular physical activity reduces the risk of premature death and disability, accurate methods of population-based measurement are important for public health surveillance efforts such as those based on the Behavioral Risk Factor Surveillance System (BRFSS). The present study: 1) briefly reviews and compares currently available methods to measure physical activity using BRFSS data, 2) describes physical activity patterns in the United States using these state-aggregated measures, and 3) provides suggestions on future directions for practitioners and researchers. Using a random-digit dialing, telephone survey, we collected data for noninstitutionalized adults aged 18 yr and older. We analyzed BRFSS data for 1996 from 50 states and the District of Columbia and Puerto Rico (N = 124,085). Based on recent literature and public health priorities, we developed eight different physical activity indices (one vigorous and seven moderate). These varied in their threshold for duration, kcal expenditure, and in frequency and intensity of activity. RESULTS: Using different algorithms, the population prevalence of moderate physical activity ranged from about 20% to 38%. Only 20% of adults met the Healthy People 2000 definition for regular, sustained activity (> or =30 min of moderate activity per day for at least 5 d x wk(-1)). CONCLUSIONS: Considerable progress is needed if the United States is to reach the current public health goal for regular physical activity. Standardized approaches to analyzing and collecting physical activity data are essential for public health surveillance, policy making, and communication to the public.

Fifty years of the congress of neurological surgeons: foundations, objectives, and legacies.

As the Congress of Neurological Surgeons (CNS) approaches its 50th anniversary, we review the genesis of our professional society, the environment in which it was created, and the legacies it has established. The CNS was the first nonexclusive, international neurosurgical organization with no ostensible limitations to membership. From its unpretentious origins, the CNS has grown remarkably in size and scope, yet it has remained focused on its original primary objectives: education, the young neurosurgeon, membership, and volunteerism for the benefit of our specialty. During its 50-year history, the CNS has established a number of lasting legacies that have positively influenced the development and maturation of our chosen specialty. Neurosurgery is unique in having benefited from two strong national member organizations to ensure representation of different generations and perspectives for policy-making, to provide for two comprehensive annual meetings and complimentary journals, to broaden the representation for neurosurgery in our interaction with outside agencies, and to minimize the cost of services provided on behalf of neurosurgeons.

Providing culturally sensitive health care to Hispanic clients.

By the year 2000, Hispanics will outnumber African Americans and become the majority minority. Statistics reveal that health problems of the three main groups of Hispanics in the United States (Mexican Americans, Puerto Ricans, and Cubans) include diabetes, injuries and violence, substance abuse, HIV/AIDS, limited access to health care, and many other problems shared by the poor and disenfranchised. The health care provider may intervene with Hispanic clients and communities in culturally sensitive ways such as viewing culture as an enabler rather than a resistant force, incorporating cultural beliefs into the plans of care, stressing familialism, taking the time for "pleasant conversation," refraining from harsh criticism, and involving the community in preventive health care programs. Such interventions require providers who are knowledgeable about the culture, customs, beliefs, and language of the Hispanics within their practice area. Health care providers also need to be alert to and active in health care policy making that will improve access to health care for the growing Hispanic population.

Science, society, and disease: emerging perspectives.

The understanding of tuberculosis (TB) requires effective links to be made between advances in biomedical knowledge and the wider social and economic dynamics of disease epidemiology. This review highlights some recent advances in contemporary TB research with particular emphasis on the spread of multidrug-resistant tuberculosis (MDR-TB); the prevalence of TB in prisons, urban ghettoes, and the marginalized communities of the South; and the relation between TB control and general developments in public policy making. The article also draws attention to the significance of new historical insights into the epidemiological transition of the twentieth century and the implications of new and emerging diseases for the future of public health. It is concluded that the real obstacles to the effective control of TB are political rather than scientific.

Public health surveillance of diabetes in the United States.

The Centers for Disease Control and Prevention Division of Diabetes Translation supports a national and state surveillance system that analyzes, interprets, and reports on diabetes risk behaviors, risk factors, care practices, morbidity, and mortality. Data sources include surveys, the U.S. Renal Data System, the Indian Health Service, information on hospital inpatients, birth and death certificates, and special studies to use and to better understand the usefulness of data from managed care, Medicare, and Medicaid for monitoring diabetes. These data are used to define the magnitude and burden of diabetes; monitor changes in burden over time; guide public health planning and policy making, and assess progress toward diabetes objectives, such as those in Healthy People 2010. Challenges facing the diabetes surveillance system are limitations in data sources; the capture of undiagnosed diabetes; tracking key risk factors, such as levels of glycemia and lipids; and surveillance of high- or emerging-risk populations such as racial and ethnic groups, children and youth, and those with prediabetes. Limited resources, competing priorities, and issues of data privacy also challenge surveillance. To overcome these factors, the Division of Diabetes Translation strongly emphasizes partnering with other organizations, such as the Medicare and Medicaid programs, managed care, and other chronic disease programs.

Cesarean delivery on maternal request: obstetrician-gynecologists' knowledge, perception, and practice patterns.

OBJECTIVE: To examine obstetrician-gynecologists' knowledge, opinions, and practice patterns related to cesarean delivery on maternal request. METHODS: Questionnaires were mailed to 1,031 American College of Obstetricians and Gynecologists Fellows in February 2006, with a response rate of 68%. The questionnaire queried respondents' demographic characteristics, practices and attitudes surrounding vaginal and cesarean deliveries, knowledge and beliefs regarding the risks and benefits of elective and nonelective cesarean delivery, and counseling practices and department policies for cesarean delivery on maternal request. RESULTS: About half of respondents believe women have the right to cesarean delivery on maternal request, and a similar percentage acknowledge having performed at least one cesarean delivery on maternal request. Fifty-eight percent of respondents note an increase in patient inquiries regarding cesarean delivery over the past year, yet most of their practices do not have a policy regarding this procedure. Respondents attribute the increase in inquiries to the increase of information from the media and to convenience. Respondents cited more risks than benefits of cesarean delivery on maternal request, and nearly all discuss these risks with patients who are considering one. Females were more negative toward cesarean delivery on maternal request than males and endorsed more risks and fewer benefits. There were no relationships between assessment of risks and benefits or practice with clinician age or patient characteristics. CONCLUSION: Most obstetrician-gynecologists in this study recognized an increased demand for cesarean delivery on maternal request within their practices, while believing that the risks of this procedure outweigh the benefits. Clinicians would benefit from strong evidence regarding risks and benefits, evidence that is crucial to guiding policy making with regard to cesarean delivery on maternal request. LEVEL OF EVIDENCE: III.

ISCORS Catalog of References to Parameter Values and Distributions Used in Environmental Pathway Modeling for Cleanup of Sites Contaminated with Radioactivity.

Federal and state regulatory agencies that are concerned with issues of environmental management have adopted approaches toward policy-making that are dose- and risk-informed. To that end they (and others) have developed environmental models and computer codes to mimic the transport of contaminants along air, water, food-chain, and related pathways for estimating potential exposures, doses, and risks to individuals, populations, and ecosystems. Their calculations commonly find application in the planning of remediation, and thereafter in the demonstration of compliance with federal and state cleanup standards. As the models and codes have become more sophisticated, so also have requirements on the accuracy and level of detail of the numerical point values and probability distributions of environmental transfer factors and other parameters that serve as input parameters to them. In response to this growing need, the federal Interagency Steering Committee On Radiation Standards (ISCORS) and the Argonne National Laboratory have developed an on-line, national repository of information on parameter values and distributions of known provenance and demonstrated utility. The ISCORS Catalog of References to Parameter Values and Distributions Used in Environmental Pathway Modeling for Cleanup of Sites Contaminated with Radioactivity is a web-based, indexed compilation of references, compendia, databases, and other sources of peer-reviewed information on parameters. It does not itself contain numerical point values or distributions for any particular parameter, but rather it provides links or directions to sites or other published materials where such information can be obtained. Designed to be user-friendly, easily searchable, and readily up-dateable, the Catalog is being filled, after some initial priming, mainly through on-line submissions of proposed references by the Catalog users themselves. The relevant information on a proposed reference is submitted to ISCORS in a simple, standardized format; it is vetted (with acceptance criteria such as publication in a peer-reviewed technical journal, or appearance in a formally-issued federal agency report) and then added semi-automatically to the Catalog. Built around a relational database, the system offers subject- and text-search capabilities, provides information on parameter definitions and methods of measurement, on transport/exposure pathways, and on standard models and codes. The Catalog is intended for use by (and being populated by) the professionals, managers, and others involved or interested in the application of pathway modeling to estimate doses and risks associated with sites contaminated with radioactive or other hazardous materials.

Utilities for prostate cancer health states in men aged 60 and older.

PURPOSE: We sought to measure utilities for prostate cancer health states in older men. METHODS: A total of 162 men aged 60 years or older (52% of whom had been diagnosed with prostate cancer) provided standard gamble utilities for 19 health states associated with prostate cancer or its treatment using an interactive, computer-based utility assessment program. Demographics and experience with specific health states were examined as predictors of ratings using ordinary least squares regression analysis. RESULTS: Mean utilities ranged from 0.67 to 0.84 for living with symptom-free cancer under conservative management ("watchful waiting") and from 0.71 to 0.89 for symptoms occurring with treatment (prostatectomy, radiation, and hormone ablation). For long-term treatment complications, bowel problems (0.71) were rated as significantly worse than impotence (0.89), urinary difficulty (0.88), or urinary incontinence (0.83). Combinations of these conditions were rated as significantly worse than individual component states. Men who had experienced impotence or urinary incontinence rated these states as slightly better than men who had not experienced the specific problems. CONCLUSIONS: Both "watchful waiting" and treatment complications from prostate cancer treatments can have large impacts on quality of life. Mean ratings are important for use in policy-making and cost-effectiveness analyses. Variation in ratings across patients suggests that mean scores do not reflect individual preferences and that shared decision-making may be best for clinical decisions.

Palaeoclimatic insights into future climate challenges.

Palaeoclimatic data document a sensitive climate system subject to large and perhaps difficult-to-predict abrupt changes. These data suggest that neither the sensitivity nor the variability of the climate are fully captured in some climate-change projections, such as the Intergovernmental Panel on Climate Change (IPCC) Summary for Policymakers. Because larger, faster and less-expected climate changes can cause more problems for economies and ecosystems, the palaeoclimatic data suggest the hypothesis that the future may be more challenging than anticipated in ongoing policy making. Large changes have occurred repeatedly with little net forcing. Increasing carbon dioxide concentration appears to have globalized deglacial warming, with climate sensitivity near the upper end of values from general circulation models (GCMs) used to project human-enhanced greenhouse warming; data from the warm Cretaceous period suggest a similarly high climate sensitivity to CO(2). Abrupt climate changes of the most recent glacial-interglacial cycle occurred during warm as well as cold times, linked especially to changing North Atlantic freshwater fluxes. GCMs typically project greenhouse-gas-induced North Atlantic freshening and circulation changes with notable but not extreme consequences; however, such models often underestimate the magnitude, speed or extent of past changes. Targeted research to assess model uncertainties would help to test these hypotheses.

Cost-effective emission abatement in europe considering interrelations in agriculture.

Agriculture is an important source of ammonia (NH3), which contributes to acidification and eutrophication, as well as emissions of the greenhouse gases nitrous oxide (N2O) and methane (CH4). Controlling emissions of one of these pollutants through application of technical measures might have an impact (either beneficial or adverse) on emissions of the others. These side effects are usually ignored in policy making. This study analyses cost-effectiveness of measures to reduce acidification and eutrophication as well as agricultural emissions of N2O and CH4 in Europe, taking into account interrelations between abatement of NH3, N2O, and CH4 in agriculture. The model used is based on the RAINS (Regional Air pollution INformation and Simulation) model for air pollution in Europe, which includes emissions, abatement options, and atmospheric source-receptor relationships for pollutants contributing to acidification and eutrophication. We used an optimisation model that is largely based on the RAINS model but that also includes emissions of N2O and CH4 from agriculture and technical measures to reduce these emissions. For abatement options for agricultural emissions we estimated side effects on other emissions. The model determines abatement strategies to meet restrictions on emission and/or deposition levels at the least cost. Cost-effective strategies to reduce acidification and eutrophication in Europe were analysed. We found that NH3 abatement may cause an increase in N2O emissions. If total agricultural N2O and CH4 emissions in Europe were not allowed to increase, cost-effective allocation of emission reductions over countries in Europe changed considerably.

Child injury in Israel: emergency room visits to a children's medical center.

The object of this study was to provide data for policy making and prevention program planning in Israel. The study examined all visits to the Department of Emergency Medicine at the Schneider Children's Medical Center in 1996 (41,279 visits in total). Approximately 22.6% of the emergency room patients were admitted following injury. Most (97%) were unintentional injury. Approximately 42% of the patients were less than 4 years old and about 20% were 2 years old. In all age groups, the rate of boys was double. Approximately 92% were Jews. Despite this low rate of non-Jewish patients, however, they constituted 20% of later hospitalizations. The main injuries recorded were bruises and wounds from blunt objects, falls, motor vehicle-related accidents, and sport injuries. The most commonly injured body parts were the head and upper and lower limbs. In 82%, medical treatment was reported and 7% were hospitalized. In examining injuries over the year, there were no significant differences between the different months, but there were clusters of injuries around various holidays--bicycle and skateboard accidents at Rosh Hashanah, Yom Kippur, and Succoth; pedestrian accidents around Lag BaOmer; burns on Purim, Hannukkah, and Passover; and accidental poisoning around Passover. The findings gave an indication of the nature of the injured population groups. These data could be useful for prevention strategy, both on the level of physical injury as well as on the level of the times of the year, when the risk was higher. The data collected very strongly raise the urgent need for establishing a national surveillance system, which would allow tracking injury-related data with respect to young people throughout the country.

Formal and informal authority of hospital directors.

Describes and contrasts the perceptions of formal and informal authority of hospital directors of two different kinds of organizations: hospitals that are part of public multi-hospital organizations (PMOs) and independent hospitals. Indicates that all the directors perceive their formal authority to be greater than their formal authority. However, there is a gap in the perception of formal and informal authority by directors of the two types of hospital. Directors of independent hospitals perceive themselves to have more formal and informal authority than do their colleagues at hospitals that are part of PMOs. Both structural and personal explanations for these findings are given. In addition, discusses the implications for policy making of the source of authority, informal, and formal authority in the transition to autonomous semi-independent hospitals in a changing environment.

Measuring the impact of rehabilitation services on the quality of life of disabled people in Cambodia.

The present study aimed to measure the quality of life (QOL) of disabled people in Cambodia and the impact of rehabilitation services. The categories of services were: physical rehabilitation (prosthetics/orthotics with physiotherapy); community-based rehabilitation; and (3) labour market assistance. The 164 respondents were from a range of urban and rural settings. The results suggest that QOL was substantially lower among disabled Cambodians who had received no rehabilitation services compared to those who had received one of the three categories of rehabilitation services. QOL scores tended to be highest, however, among those who had received a combination of all three services. The results also highlighted the vulnerability of certain sub-groups who may need specific provision in planning, policy-making and service delivery. The present study suggests that an integrated approach may be the best way to maximise the impact of individual rehabilitation services in Cambodia.

Tools for comparative analysis of alternatives: competing or complementary perspectives?

A third generation of environmental policy making and risk management will increasingly impose environmental measures, which may give rise to analyzing countervailing risks. Therefore, a comprehensive analysis of all risks associated with the decision alternatives will aid decision-makers in prioritizing alternatives that effectively reduce both target and countervailing risks. Starting with the metaphor of the ripples caused by a stone that is thrown into a pond, we identify 10 types of ripples that symbolize, in our case, risks that deserve closer examination: direct, upstream, downstream, accidental risks, occupational risks, risks due to offsetting behavior, change in disposable income, macro-economic changes, depletion of natural resources, and risks to the manmade environment. Tools to analyze these risks were developed independently and recently have been applied to overlapping fields of application. This suggests that either the tools should be linked in a unified framework for comparative analysis or that the appropriate field of application for single tools should be better understood. The goals of this article are to create a better foundation for the understanding of the nature and coverage of available tools and to identify the remaining gaps. None of the tools is designed to deal with all 10 types of risk. Provided data suggest that, of the 10 types of identified risks, those associated with changes in disposable income may be particularly significant when decision alternatives differ with respect to their effects on disposable income. Finally, the present analysis was limited to analytical questions and did not capture the important role of the decision-making process itself.

A cluster-based decision support system for estimating earthquake damage and casualties.

This paper describes a Decision Support System for Disaster Management (DSS-DM) to aid operational and strategic planning and policy-making for disaster mitigation and preparedness in a less-developed infrastructural context. Such contexts require a more flexible and robust system for fast prediction of damage and losses. The proposed system is specifically designed for earthquake scenarios, estimating the extent of human losses and injuries, as well as the need for temporary shelters. The DSS-DM uses a scenario approach to calculate the aforementioned parameters at the district and sub-district level at different earthquake intensities. The following system modules have been created: clusters (buildings) with respect to use; buildings with respect to construction typology; and estimations of damage to clusters, human losses and injuries, and the need for shelters. The paper not only examines the components of the DSS-DM, but also looks at its application in Besiktas municipality in the city of Istanbul, Turkey.
