An Integrated Framework for Risk Management and Population Health

The traditional medical model of health and health policy development has focused on individuals and the role of medical care in preventing and treating disease and injury. Recent attention to health inequities and social determinants of health has raised the profile of population heath and evidence-based strategies for improving the health of whole populations. At the same time, risk science has emerged as an important new discipline for the assessment and management of risks to health. This article reviews historical developments in the fields of risk management and population health and proposes a joint population health risk management framework that integrates the key elements of both fields. Applying this integrated approach to managing population health risks will facilitate the development of evidence-based health policy. It will encourage a more systematic and comprehensive evaluation of population health issues and promote the use of a broader suite of interventions to reduce health risks and enhance population health status.     

Organization of medical care of patients with pneumonia caused by Legionella during outbreak in Sverdlovsk region

Data on organization of medical care during outbreak of Legionnaires' disease in July-August, 2007 in town Verkhnyaya Pyshma in Sverdlovsk region are presented. Special feature of this outbreak was spreading of infection in boundaries of the town with total population of 70,600 people. Results of organizational work of health authorities in order to provide timely and adequate medical care for patients with Legionnaires' disease on both outpatient and inpatient levels of care, conduction of preventive measures in foci of infection, coordination of interaction between different medical organizations and services are summarized in the article.     

Access and Use of Medical Care among Obese Persons

The prevalence of obesity and severe obesity is growing rapidly, along with obesity‐related comorbidities and mortality. Given the increased health risks associated with obesity, it is vital that obese persons have adequate access to, and make consistent use of, medical care services. Assuming obese persons have access to medical care that is comparable to non‐obese persons, one would expect to observe greater use of medical services among obese persons. In this article we briefly review empirical evidence of the access to and use of medical care among obese persons. Although certain subgroups that tend to have disproportionately high prevalences of obesity (i.e., low socioeconomic status, minority groups) have reduced access to care, no studies have specifically examined whether or not obese persons have the same access to health care as do their lean counterparts. With respect to use of health care services, however, obesity has been consistently linked with greater rates of utilization and increased health care expenditures. Both the increased use and cost appear to be largely a function of treating obesity‐associated comorbidities such as diabetes and hypertension. We conclude that, although it is clear that obesity is associated with both greater use and cost of medical care, the relationship between obesity and access to medical care has not been determined.     

Physical illness in patients with severe mental disorders. II. Barriers to care, monitoring and treatment guidelines, plus recommendations at the system and individual level

Physical disorders are, compared to the general population, more prevalent in people with severe mental illness (SMI). Although this excess morbidity and mortality is largely due to modifiable lifestyle risk factors, the screening and assessment of physical health aspects remains poor, even in developed countries. Moreover, specific patient, provider, treatment and system factors act as barriers to the recognition and to the management of physical diseases in people with SMI. Psychiatrists can play a pivotal role in the improvement of the physical health of these patients by expanding their task from clinical psychiatric care to the monitoring and treatment of crucial physical parameters. At a system level, actions are not easy to realize, especially for developing countries. However, at an individual level, even simple and very basic monitoring and treatment actions, undertaken by the treating clinician, can already improve the problem of suboptimal medical care in this population. Adhering to monitoring and treatment guidelines will result in a substantial enhancement of physical health outcomes. Furthermore, psychiatrists can help educate and motivate people with SMI to address their suboptimal lifestyle, including smoking, unhealthy diet and lack of exercise. The adoption of the recommendations presented in this paper across health care systems throughout the world will contribute to a significant improvement in the medical and related psychiatric health outcomes of patients with SMI.     

The Ecology of Medical Care in Beijing

Background

We presented the pattern of health care consumption, and the utilization of available resources by describing the ecology of medical care in Beijing on a monthly basis and by describing the socio-demographic characteristics associated with receipt care in different settings.

Methods

A cohort of 6,592 adults, 15 years of age and older were sampled to estimate the number of urban-resident adults per 1,000 who visited a medical facility at least once in a month, by the method of three-stage stratified and cluster random sampling. Separate logistic regression analyses assessed the association between those receiving care in different types of setting and their socio-demographic characteristics.

Results

On average per 1,000 adults, 295 had at least one symptom, 217 considered seeking medical care, 173 consulted a physician, 129 visited western medical practitioners, 127 visited a hospital-based outpatient clinic, 78 visited traditional Chinese medical practitioners, 43 visited a primary care physician, 35 received care in an emergency department, 15 were hospitalized. Health care seeking behaviors varied with socio-demographic characteristics, such as gender, age, ethnicity, resident census register, marital status, education, income, and health insurance status. In term of primary care, the gate-keeping and referral roles of Community Health Centers have not yet been fully established in Beijing.

Conclusions

This study represents a first attempt to map the medical care ecology of Beijing urban population and provides timely baseline information for health care reform in China.     

Health status and national health priorities.

Various measures of the health status of the population of the United States show there is considerable room for improvement. Compared with other industrialized nations, we are spending more for health care but our health is worse. These data form the basis for setting national priorities. Four selected policy issues are discussed, including access to medical care, maternal and child health care, the acquired immunodeficiency syndrome, and long-term care. Examination of these issues leads to the conclusion that universal and affordable health care is the major national health priority, requiring a commitment by the people of the United States and its leaders to develop a viable solution.     

Overweight,Medical Comorbidity and Health‐related Quality of Life in a Community Sample of Women and Men

Associations among gender, overweight and obesity, medical comorbidity, and health‐related quality of life (HRQoL) were examined in a general population sample of 4,181 women and men aged 18–65 years. Anthropometric measurements and medical comorbidity were assessed as part of a computer‐assisted physician interview. HRQoL was assessed with the Physical and Mental Component Summary scales of the Medical Outcomes Study Short Form (SF‐36 PCS, MCS). General linear models were used to examine the associations among gender, weight status, medical comorbidity, and HRQoL. Controlling for age, social status, the occurrence of specific medical conditions, and the total number of medical conditions, mild obesity was associated with impairment in physical health functioning, as measured by the PCS, among women, whereas impairment in men's physical health was apparent only for moderate obesity. There was no association between weight status and psycho‐social functioning, as measured by the MCS, in women, whereas overweight was associated with better perceived psycho‐social functioning in men. The findings are consistent with the hypothesis that w omen suffer a disproportionately large share of the disease burden of overweight and obesity that is not due solely to differences in medical comorbidity. The possibility that aspects of emotional well‐being may mediate the association between obesity and physical health functioning warrants further attention in this regard. The findings also indicate the need to stratify data by gender and to include more sensitive measures of psycho‐social functioning in future studies.     

Health departments in the U.S. 1920-1988: statements of mission with special reference to the role of C.-E.A. Winslow.

The mission of local health departments in the U.S. is traced from the 1920s to the present through examination of official promulgations of the American Public Health Association and other organizations. As the communicable diseases came under general control, this mission was conceived more broadly. Nevertheless, in effect their public health role was diminished due to the rapid ascendancy of private and not-for-profit medical care, which consistently sought to keep public health out of potential areas of competition. Thinking both within the public health field (as represented by C.-E.A. Winslow) and outside the public health field (as represented by the American Medical Association), had created boundaries limiting public health's role to preventive medical services. This restriction, in turn, largely excluded the public health field from participation in the tremendous expansion of medical care since World War II. The public health role was further limited in 1970 by the removal of much of environmental pollution from its purview. The sum of these and other forces has left the public health field weakened and in considerable confusion about its role at a time when the resurgence of infectious disease (e.g., AIDS and Lyme disease), environmental hazards, and medical care institutions requires a strong public health presence.     

The future of family practice training in California.

Although the number of physicians in California has doubled since 1963, the number of family and general practice physicians has declined. The ratio of office-based primary care physicians to population has also decreased. Graduate medical education is funded largely from patient care revenues, but the low rate of reimbursement for ambulatory care makes training in primary care specialties especially dependent on public support. Medicare, the Veterans Administration, and the University of California provide more than $325 million a year in support of graduate medical education in California. Federal and state grant programs provide $5 million a year for family physician training in the state, but appropriations to these programs have been reduced in real terms. California family practice residencies are disproportionately located at county hospitals, where funding shortfalls make them especially vulnerable to cuts in grant programs. Additional resources will be needed if more family physicians are to be trained.     

Medical care for Russian cosmonauts on board the ISS

Established with the personal participation of O.G. Gazenko, the Russian system of medical care for cosmonauts has been largely preserved to this day. The system was fully functional on board the orbital complex Mir and, with appropriate modifications, has been adopted as the core of the medical care for Russian members of ISS crews. In 2000–2008, 22 cosmonauts were members of 17 ISS missions lasting from 140 to 216 days. The main functions of the medical care system were to control health, physical, and mental performance, and to support space research. Readaptation to normal gravity was, in most cases, similar to what has been typical on the return from Russian orbital stations; some deviations are accounted for by the use of in-flight countermeasures. The paper presents some aspects of the theoretical work of Academician Gazenko in the field of medical care in space flights. It outlines the principles of ISS medical management. The integrated medical support system combines medical equipment and items available in the Russian and U.S. segments; the integrated medical group consists of flight surgeons, medical experts, and biomedical engineers of international partners and coordinates the planning and implementation of medical operations. In addition, challenges of health care in the phase of ISS operation are defined.     

Developments for a growing Japanese patient population: facilitating new technologies for future health care

Lung cancer, COPD and cardiovascular diseases are highlighted as some of the most common disease that cause mortality, and for that reason are the most active areas for drug development. This perspective paper overviews the urgent need to develop a health care system for a rapidly growing patient population in Japan, including forthcoming demands on clinical care, expecting outcomes, and economics. There is an increasing requirement to build on the strengths of the current health care system, thereby delivering urgent solutions for the future. There is also a declaration from the Ministry of Health, Labour and Welfare (MHLW), to develop new biomarker diagnostics, which is intended for patient stratification, aiding in diagnostic phenotype selection for responders to drug treatment of Japanese patients. This perspective was written by the panel in order to introduce novel technologies and diagnostic capabilities with successful implementation. The next generation of personalized drugs for targeted and stratified patient treatment will soon be available in major disease areas such as, lifestyle-related cancers, especially lung cancers with the highest mortality including a predisposing disorder chronic obstructive pulmonary disease, cardiovascular disease, and other diseases. Mass spectrometric technologies can provide the "phenotypic fingerprint" required for the concept of Personalized Medicine. Mass spectrometry-driven target biomarker diagnoses in combination with high resolution computed tomography can provide a critical pathway initiative facilitated by a fully integrated e-Health infrastructure system. We strongly recommend integrating validated biomarkers based on clinical proteomics, medical imaging with clinical care supported by e-Health model to support personalized treatment paradigms to reduce mortality and healthcare costs of chronic and co-morbid diseases in the elderly population of Japan.     

Use of alternative medicine by patients attending a gastroenterology clinic.

We carried out a study to determine the proportion of patients attending a university-based gastroenterology outpatient clinic who sought alternative medical care for the same health problem that had prompted them to see a gastroenterologist. After the patients completed a self-administered questionnaire, the gastroenterologist gave a diagnosis and assigned a functional rating. Of the 395 patients 287 (73%) had not used alternative medicine, and 36 (9%) had sought alternative medical care for the problem that had prompted them to see a gastroenterologist. There were no significant differences between alternative medicine users and nonusers in sociodemographic characteristics, use of health care services or general health status. Patients with a functional disease were more likely to seek alternative medical care than those with organic disease (33% v. 7%) (p less than 0.0001). Fewer alternative medicine users (54%) than nonusers (85%) were satisfied with conventional medicine (p less than 0.001), and more alternative medicine users (49%) than nonusers (13%) were very sceptical of conventional medicine (p less than 0.0001).

Hypoplasia and health status: a comparison of two lifestyles

Enamel hypoplasia was recorded for the primary and permanent teeth of Natufians (terminal Pleistocene Hunter-Gatherers) and Early Arabs (Subsistence farmers). Minimal hypoplasia was found in the primary teeth of the Natufians, but in the Early Arab population, 31% of upper first primary molars showed enamel defects. In the permanent teeth, the Early Arab population again showed a significantly higher frequency of hypoplasia, with all teeth affected. In the Natufians, only later developing teeth showed enamel defects. These findings suggest that health status in the Early Arab population was poor throughout life, affecting pregnant mothers, their foetuses, young infants and children. These results confirm other studies that have shown deterioration in health status of early agriculturalists relative to hunter- gatherers. Comparisons of these findings with those of recent populations indicate that health status in the Natufians was comparable to that of modern populations with subsistence diets and mediocre health care. Health status in the Early Arab population was comparable to that of modern populations suffering from severe malnutrition and chronic disease.     

Cardiovascular Disease Prevention and Care in Latino and Hispanic Subjects

ObjectiveTo determine the scope, impact, and health care limitations relative to cardiovascular disease (CVD) in the Latino-Hispanic population.MethodsWe reviewed MEDLINE and PubMed for studies published from January 1995 to June 2005 using a combination of search terms (epidemiology, Hispanic, CVD) and chose articles for review on the basis of direct informational relevance to the current status of preventive treatment and barriers to health care for CVD among the Latino-Hispanic community. Additional information was gathered through a general Internet search by using Google with the aforementioned search terms and a review of the US Bureau of the Census and governmental statistics related to these terms found through governmental Web sites.ResultsFor proactive reduction of rates of CVD among the Latino-Hispanic population in the United States, preventive interventions should be targeted. Several barriers exist to providing effective preventive care to the Latino-Hispanic community. Medical research involving the Latino-Hispanic population is sparse, many Latino and Hispanic subjects do not have health insurance or a regular source of health care, and poor English-language ability and low education and literacy levels limit awareness and inhibit communications between Latino and Hispanic persons and the health care system.ConclusionThe prevalence and growth of CVD in the US Latino-Hispanic community provide a clear warning that the public health problem presented by CVD in the Latino-Hispanic population is already substantial and will become much more severe in the coming decades. Actions to manage and minimize this problem are urgently needed. (Endocr Pract. 2007;13:77-85)     

Public mental health: the time is ripe for translation of evidence into practice

Public mental health deals with mental health promotion, prevention of mental disorders and suicide, reducing mental health inequalities, and governance and organization of mental health service provision. The full impact of mental health is largely unrecognized within the public health sphere, despite the increasing burden of disease attributable to mental and behavioral disorders. Modern public mental health policies aim at improving psychosocial health by addressing determinants of mental health in all public policy areas. Stigmatization of mental disorders is a widespread phenomenon that constitutes a barrier for help-seeking and for the development of health care services, and is thus a core issue in public mental health actions. Lately, there has been heightened interest in the promotion of positive mental health and wellbeing. Effective programmes have been developed for promoting mental health in everyday settings such as families, schools and workplaces. New evidence indicates that many mental disorders and suicides are preventable by public mental health interventions. Available evidence favours the population approach over high-risk approaches. Public mental health emphasizes the role of primary care in the provision of mental health services to the population. The convincing evidence base for population-based mental health interventions asks for actions for putting evidence into practice.     

PROBLEMS ASSOCIATED WITH MEDICAL DISASTER CARE—Preparations in a Large Southern California Area

In the organization for dealing with medical disaster, the region is in an intermediary position, between the State Disaster Office and the operational areas. Regional functions are largely those of coordinating the activities of the areas, and are based upon directives and plans from the state level.The regional medical chief is a member of the staff of the Civil Defense coordinator and must advise him in all matters related to the health of the people, including medical and casualty care, hospitalization, public health, sanitation, preventive medicine and the special problems of biological, chemical and radiation hazards. Coordination with the other Civil Defense services is necessary.The basic medical plan is to give emergency care in the first aid stations and then evacuate casualties to hospitals when and how the situation permits. Regional function is to obtain personnel, supply, equipment and hospitalization support when required.Dispersal of danger zone populations to support areas creates many medical and public health problems among the displaced people and the residents.Survival of the nation requires altered concepts of casualty management. The least injured who have the greatest productive potential should have the highest treatment priority. Short, lifesaving surgical procedures must have precedence over long, complicated operations.No plan is any better than the individual doctors, nurses and other personnel who will put it into operation.     

Socio-Economics of Medical Care, Report of Bureau of Research and Planning

Interest in the area of medical socio-economics has largely come about due to the proliferation of social welfare programs and advances in the distribution of health services in the private sector of the economy. The increasing role of our government has also been a stimulus. With the advent of new techniques for the financing of care, a large volume of institutional literature has appeared delving into issues which range from the role of the medical profession in the evaluation of quality of medical care to the measurement of demand for and prepayment of numerous types of health care services. Since the area of medical socio-economics is not considered "pure" enough to be categorized as a discipline, the range of periodicals, government and non-government publications and books, in which data are found, is vast. This report will briefly describe some of the more important sources of data in the area of medical socio-economics. Major emphasis is given to the literature which provides current statistical data on the operational aspects of public and private programs providing health care services, and ancillary activities which affect the market for health care activities. Leading publications of governmental and other community agencies are cited to illustrate the range of materials available to the public and to the medical profession.     

Changes of adult population health status in China from 2003 to 2008

Objectives

The purpose of this study was to examine the change in health status of China''s adult population between the years of 2003 and 2008 due to rapid economic growth and medical system improvement.

Methods

Data from the third and fourth Chinese national health services surveys covering 141,927 residents in 2003 and 136,371 residents in 2008 who were aged >18 years were analyzed.

Results

Chinese respondents in 2008 were more likely to report disease than in 2003. Smoking slightly decreased among men and women, and regular exercise showed much improvement. Stratified analyses revealed significant subpopulation disparities in rate ratios for 2008/2003 in the presence of chronic disease, with greater increases among women, elderly, the Han nationality, unmarried and widow, illiterate, rural, and regions east of China than other groups.

Conclusions

Chinese adults in 2008 had worse health status than in 2003 in terms of presence of chronic disease. China''s reform of health care will face more complex challenges in coming years from the deteriorating health status in Chinese adults.     

The benefits of privatization.

The promise of a universal, comprehensive, publicly funded system of medical care that was the foundation of the Medical Care Act passed in 1966 is no longer possible. Massive government debt, increasing health care costs, a growing and aging population and advances in technology have challenged the system, which can no longer meet the expectations of the public or of the health care professions. A parallel, private system, funded by a not-for-profit, regulated system of insurance coverage affordable for all wage-earners, would relieve the overstressed public system without decreasing the quality of care in that system. Critics of a parallel, private system, who base their arguments on the politics of fear and envy, charge that such a private system would "Americanize" Canadian health care and that the wealthy would be able to buy better, faster care than the rest of the population. But this has not happened in the parallel public and private health care systems in other Western countries or in the public and private education system in Canada. Wealthy Canadians can already buy medical care in the United States, where they spend $1 billion each year, an amount that represents a loss to Canada of 10,000 health care jobs. Parallel-system schemes in other countries have proven that people are driven to a private system by dissatisfaction with the quality of service, which is already suffering in Canada. Denial of choice is unacceptable to many people, particularly since the terms and conditions under which Canadians originally decided to forgo choice in medical care no longer apply.
