Sociometric risk networks and risk for HIV infection.

OBJECTIVES: This study examined whether networks of drug-injecting and sexual relationships among drug injectors are associated with individual human immunodeficiency virus (HIV) serostatus and with behavioral likelihood of future infection. METHODS: A cross-sectional survey of 767 drug injectors in New York City was performed with chain-referral and linking procedures to measure large-scale (sociometric) risk networks. Graph-theoretic algebraic techniques were used to detect 92 connected components (drug injectors linked to each other directly or through others) and a 105-member 2-core within a large connected component of 230 members. RESULTS: Drug injectors in the 2-core of the large component were more likely than others to be infected with HIV. Seronegative 2-core members engaged in a wide range of high-risk behaviors, including engaging in risk behaviors with infected drug injectors. CONCLUSIONS: Sociometric risk networks seem to be pathways along which HIV travels in drug-injecting peer groups. The cores of large components can be centers of high-risk behaviors and can become pockets of HIV infection. Preventing HIV from reaching the cores of large components may be crucial in preventing widespread HIV epidemics.

Development of provider networks for specific diseases.

Carve out contracting for specific diseases and specialty services has become extremely common in a very short time. The goal of carve out contracting is simple: to place responsibility for managing care and its cost in the hands of those best suited to provide and manage care. This article provides an overview of carve out contracting for specific diseases. While the article focuses on business and legal issues relating to AIDS/HIV and ESRD, the principles discussed are applicable to numerous diseases.

[Role of the social support network which influences age of death and physical function of elderly people: study of trends in and outside of Japan and future problems].

Concerning associations between the social support network and physical health of the elderly, longitudinal studies have been conducted using various measurement indexes. The studies indicated that the support network influences on physical function and life expectancy. In this study we compared research papers from Japan and elsewhere that appeared after 1980, from the viewpoint of 1) social support effects, and 2) social network effects, to examine potential problems in the future. The main knowledge obtained was that the receipt of emotional support, wide network size, and participation in social activities reduced the risk of early death and decrease in physical function of elderly people. Sex differences were indicated, and in many cases, the effects were more remarkable in men than women. In addition the positive influence of receiving help from a support network, a major subject of conventional research, the effects of offering help to others and negative findings were also examined. It has been indicated that participation in volunteer groups and offer of support to other people can prevent decrease in physical function or early death. As negative effects, improper instrumental support rather disturbs the mental and physical independence of elderly people. As future issues, it is necessary to focus on both positive/negative and receipt/offer effects of support network, and to clarify how to provide example which best match the life of elderly people by comparing sexes and regions. It is also important to actually apply the knowledge gained from observational studies to prevent the elderly from becoming a condition requiring care, and to develop intervention studies which can increase the social contacts of elderly people at the same time as conducting health education and medical treatment.

Recent syphilis trends in Belgium and enhancement of STI surveillance systems.

Over the past five years, a series of syphilis outbreaks mainly occurring among gay men have been observed in Europe. One of these outbreaks was reported in the city of Antwerp, Belgium, during the first quarter of 2001. This outbreak is still ongoing in 2004. Furthermore, active syphilis diagnoses reported by the Sentinel Laboratory Network rose by 89% in the country during the fourth quarter of 2003. An increase in Brussels was also observed during the same quarter (+300%; 24 cases reported). Overall, the sentinel network of clinicians reported that 93.4% of patients were male; among them, 79.9% were men having sex with men (MSM). The overall proportion of patients co-infected with HIV was 50.5% (MSM: 58.6%; male heterosexuals: 23.8%; females: 8.3%); 76.1% of co-infected patients were already aware of their HIV infection at the time they were diagnosed with syphilis.

Satellite exchange in the Baltimore Needle Exchange Program.

OBJECTIVE: Our first objective was to develop an index of satellite exchange and then determine whether satellite exchangers (SEs) differed demographically or behaviorally from other injecting drug users (IDUs). Our second objective was to determine the degree that SEs contributed to needle exchange program (NEP) effectiveness. METHODS: We collected data from approximately 5000 Baltimore Needle Exchange Program (BNEP) participants on the number of syringes acquired and returned over the two-year period February 1995 to February 1997. We then conducted one-way ANOVAs and logistic regressions to determine if SEs were different from other IDUs. RESULTS: We classified 9.35% of the IDUs and SEs and showed that SEs reported levels of drug use and risk behavior similar to other BNEP participants. Although SEs represented less than 10% of all BNEP clients, they accounted for more than 64% of all needles distributed by the BNEP. We showed that SEs accessed more wide-ranging drug use networks than non-SE IDUs and thus can act as potential bridges for human immunodeficiency virus (HIV) prevention materials and messages to larger numbers of drug injectors. CONCLUSIONS: SEs can be expressly targeted with specific prevention messages and encouraged to be "ambassadors" for HIV prevention messages. Efforts to curtail the activities of SEs may detract from the effectiveness of NEPs.

Community-based dental programs: University of Medicine and Dentistry of New Jersey-New Jersey Dental School.

The dental school plans to incorporate CODE into the curriculum so that more students have community-based dental educational experiences. Future plans also include increasing standardization of reports, clinical and administrative procedures, resources, and processes across the sites in order to lower managerial overhead. This process will be aided by further enhancement of computerized information systems and electronic links. The major lesson learned is that new extramural programs can be created and sustained by pooling school resources with those from the private and public sectors. Funding sources and opportunities available to one party alone are insufficient. While one-time funding was used to build and furnish the NJDS extramural sites, the clinics were established only after business plans demonstrated the availability of funds to sustain their operations. The Statewide Network of Community Oral Health Care and CODE models are still evolving, but they are replicable not only in dental education but in other types of health services. The details of the partnerships and funding streams will vary from site to site, but through outreach and careful negotiation with potential partners and detailed contracts, the community service and educational missions of a health professions school can have a successful outcome.

[Networking: ambulatory and stationary mesdical care].

A better co-operation between health care sectors and primary and specialised treatment levels is inevitable for ensuring good patient care. Many informal co-operations already exist, and their experience may be used for developing new forms of co-operation. Therefore, the existing legal basis has to be changed, barriers must be abolished and new incentives established. Quality management that is both practicable and adapted to the needs of these new forms of patient care must be an integral part of this development.

Waiting for cardiac surgery--support experienced by next of kin.

BACKGROUND: Next of kin (NoK) play a crucial role for patients waiting for cardiac surgery. AIM: To describe experience of support, in the form of important events, by next of kin while their intimates were waiting for a heart operation. METHODS: The design was qualitative and the "critical incident" technique was used. Incidents were collected via interviews with 23 next of kin to patients waiting for heart surgery and the informants were chosen by the patient themselves. FINDINGS: In all, 224 important events, both positive and negative, were identified in the interviews and two main areas emerged in the analysis: internal factors and external factors. Positive internal factors were associated with finding strength, whereas negative factors were associated with uncomfortable feelings. Positive external factors were associated with participating in care and receiving attention, whereas negative factors were associated with dissatisfaction with the health-care organization and failing social network. CONCLUSION: This study shows that next of kin experienced positive support when they received attention and information and felt involvement in the care. An important implication for the health-care professionals and public authorities is the understanding of the experience of support expressed by next of kin, to provide them with optimal information and support.

How much does social capital add to individual health? A survey study of Russians.

Some Russians are healthier than others. To what extent does their health vary with involvement or exclusion from social capital networks? The first section reviews alternative theories: human capital as the primary determinant; social capital, whether generic, situation-specific or simply a new label for old measures of social integration; or a composite theory--both human and social capital are major determinants of health. The evidence to test hypotheses consists of individual-level data about self-assessed physical and emotional health from the special-purpose social capital questionnaire used in the 1998 New Russia Barometer survey, a nationwide representative sample of the adult Russian population. Multiple regression analysis shows that on their own human capital and social capital each account for a notable amount of variance in health. When both forms of capital are combined in a composite model, each retains major influence, demonstrating that social capital does make an independent contribution to health. Significant social capital influences include involvement or exclusion from formal and informal networks; friends to rely on when ill; control over one's own life; and trust. Significant human capital influences besides age include subjective social status, gender and income. Regression-based estimates of impact show that social capital increases physical and emotional health more than human capital; together they can easily raise an individual's self-reported health from just below average on a five-point scale to approaching good health.

Application of peer-to-peer networking to health care.

People with chronic illness or disability share similar information needs that are not routinely handled by a system designed for traditional health services. Recent historical initiatives to provide alternate information systems for sharing information or coordinating services have been highly centralized, were expensive to set up and were not sustainable. We propose a novel application of peer-to-peer networking to provide an infrastructure for information exchange and service coordination. The peer-to-peer model empowers the user (citizen with disabilities) with control over the type and extent of information about themselves that is communicated and to whom. Further, the peer-to-peer model leads to a decentralized resource that grows incrementally, supported by the users, and is potentially more sustainable.

A typological approach to the study of rural HIV service delivery networks.

Despite the rapid growth of AIDS cases in nonmetropolitan areas, little is known about the characteristics and needs of HIV-positive rural residents or how rural areas are responding to the epidemic. This paper proposes a typology for distinguishing among rural environments and examining variations in HIV service networks. The typology identifies three dimensions that have a major effect on the development of rural HIV service networks: degree of rurality, the prevalence of AIDS, and the epidemiological and demographic characteristics of the infected populations. Data from four case studies are used to illustrate how variations in rural environments can affect the organization and delivery of HIV/AIDS care. The typology contributes to public policy discussions by identifying key attributes of rural environments that influence program planning and implementation and the transferability of service delivery models.

Regionalization of infection prevention and control services in a publicly funded health care system.

In 1994 health services in the Edmonton region were consolidated into an integrated network called Capital Health. Infection control professionals in the region met to develop a vision for the future of infection control; the tasks were to prepare a proposal for a regional program, develop indicators for outcome measurements, and standardize guidelines and products. Although regionalization of infection control is a complex process, we have had success with a proactive approach led by infection control professionals.

Developing a health information network within an integrated delivery system: a case study.

Changes in the health care environment, such as the growth of integrated delivery systems and the proliferation of managed care, are having a profound impact on the way in which health care organizations manage both clinical and financial information. Health information networks (HINs) are emerging to support the goals and internal needs of integrated delivery systems. In this environment, health care managers must assume a leadership role in planning for the development of HINs. The article provides an overview of the principal issues that should be addressed in an organization's information systems plan when a HIN is being developed and includes a case study that illustrates the key points discussed.

The Great Lakes Regional Stroke Network experience.

Stroke is a leading cause of disability and the third leading cause of death among adults in the United States and in the Great Lakes states of Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. The Great Lakes Regional Stroke Network was created to enhance collaboration and coordination among the Great Lakes states to reduce the burden of stroke and stroke-related disparities associated with race, sex, and geography. Three priorities were identified for reducing the effects of stroke in the Great Lakes region: 1) build epidemiologic capacity to improve stroke prevention and control efforts, 2) facilitate systems-level changes and collaborative efforts to improve acute stroke care and rehabilitation, and 3) promote awareness of the warning signs of stroke and the need to call 911. The Great Lakes Regional Stroke Network has work groups in the areas of epidemiology and surveillance, health care quality improvement, and public education. These groups recommend initiatives to states for their efforts to reduce the effects of stroke within the Great Lakes region. Examples of recommended initiatives include identifying and prioritizing state research evaluation needs for stroke, conducting a stroke education media campaign, and developing a statewide emergency medical services protocol for stroke.
