Reaching Hispanics with messages to prevent alcohol and other drug abuse.

Hispanics are often labeled a "hard-to-reach" population in the context of health communications, yet there are indicators that corporate interests increasingly are reporting successes in designing advertising and promotional campaigns targeting Hispanic markets. The authors suggest research priorities designed to promote more effective communications programming in the substance abuse field, and they identify three key target audiences: children and adolescents, women of childbearing age, and heavy-drinking men. The significance of the diversity within the Hispanic community; the opportunities to reinforce attitudes, norms, and behaviors that counter substance use; and the centrality of family are discussed as approaches to communications planning and message development.

A program for increasing manual signing by autistic and profoundly retarded youth within the daily environment.

A program was implemented to increase the manual signing of five profoundly retarded and four autistic youth within their daily environment. Each participant was nonvocal or minimally vocal. The program was based on modified incidental teaching strategies and was implemented by direct care personnel under supervision in an institutional setting. Specific components included rearranging the physical environment to prompt signing, altering routine staff-resident interactions to prompt, manually guide and/or reinforce signing; and conducting mini-training sessions. Additionally, staff modeled signs intermittently throughout the day. The program was sequentially implemented during two staff work shifts on each of two resident living modules. Observations conducted at four separate time periods during the day indicated that significant increases in signing occurred for all participating youth and that the increases generally maintained during follow-up checks at 5 and 17 weeks. Differential effects of the increased signing on frequency of vocalizations were noted across residents. A staff acceptability survey indicated favorable staff reports on the usefulness of signing to communicate with the youth. Results are discussed regarding the significance of manual signing for seriously developmentally disabled persons and the importance of ensuring that signing skills are used in the daily environment and not exclusively in formal training sessions. Also, areas for continued research are noted in terms of more refined analyses of client skills and subsequent progress in manual communication programs.

Trends in educational placement and cost-benefit considerations in children with cochlear implants.

OBJECTIVES: To study the effect of cochlear implantation on the use of educational resources by profoundly hearing-impaired children and to determine trends in educational cost vs benefit. DESIGN: Retrospective study and cost-benefit analysis. SETTING: Outpatient pediatric cochlear implant program in an academic institution (The Listening Center at Johns Hopkins University School of Medicine, Baltimore, Md), in collaboration with public schools in Maryland and surrounding states. PATIENTS OR OTHER PARTICIPANTS: School-aged children with profound prelingual hearing impairment without other clearly defined disabilities. Thirty-five children with multiple-channel cochlear prostheses and a comparison group of 10 children without implants from 'total communication' programs in the Maryland public school system. INTERVENTIONS: Multiple-channel cochlear implantation and at least 1 year of a systematic auditory skill development program at the Listening Center, compared with standard educational management of children with conventional amplification. MAIN OUTCOME MEASURES: Classroom placement and number of hours of special educational support used. RESULTS: A correlation was observed between the length of cochlear implant experience and the rate of full-time placement in mainstream classrooms (r = 0.10; P= .04). There was also a negative correlation between the length of implant experience and the number of hours of special educational support used by fully mainstreamed children (Pearson product moment correlation = -0.10; P = .03). Children with greater than 2 years of implant experience were mainstreamed at twice the rate or more of age-matched children with profound hearing loss who did not have implants. They were also placed less frequently in self-contained classrooms and used fewer hours of special education support. A cost-benefit analysis based on conservative estimates of educational expenses from kindergarten to 12th grade shows a cost savings of cochlear implantation and appropriate auditory (re)habilitation that ranges from $30000 to $200000. CONCLUSIONS: Cochlear implantation accompanied by aural (re)habilitation increases access to acoustic information of spoken language, leading to higher rates of mainstream placement in schools and lower dependence on special education support services. The cost savings that results from a decrease in the use of support services indicates an educational cost benefit of cochlear implant (re)habilitation for many children.

A virtual classroom for undergraduate periodontology: a pilot study.

The Integrated Distributed Learning Environments or virtual classrooms constitute a new promising structure in education of health care personnel. A virtual classroom was developed aiming to teach periodontology to an international group of 28 dental students using a problem-based learning (PBL) approach. The course was web-based and included synchronous and asynchronous communication, on-line libraries and multimedia material. Students were organised in 4 independent groups and each group was appointed a tutor. The results of the study indicate that one of the most positive effects students experienced was competence in using the computer. They also rated highly the use of multimedia for learning of clinical procedures. It was found that web boards and email were too slow to allow group work in the virtual classroom. Real time communication programs were found to be superior for problem discussion and hypothesis formulation. However, email and the web board played a significant role during certain steps of the PBL method. The students expressed a positive attitude for the combined use of network-based learning and problem-based education. Our present experience suggests that distance learning should be organised with a mixture of different media, allowing communication of knowledge and skills between the resources and the students, as well as cooperation between the students. Computer literacy among teachers and students is limited and should be enhanced. Finally, personal contact between the resource persons and the students before the distant learning course commences helps the learning process.

Pfiesteria-related educational products and information resources available to the public, health officials, and researchers.

Public and political concerns about Pfiesteria from 1997 to the present vastly exceed the attention given to other harmful algal bloom (HAB) issues in the United States. To some extent, the intense focus on Pfiesteria has served to increase attention on HABs in general. Given the strong and continuing public, political, and research interests in Pfiesteria piscicida Steidinger & Burkholder and related organisms, there is a clear need for information and resources of many different types. This article provides information on Pfiesteria-related educational products and information resources available to the general public, health officials, and researchers. These resources are compiled into five categories: reports; website resources; state outreach and communication programs; fact sheets; and training manuals and documentaries. Over the last few years there has been rapid expansion in the amount of Pfiesteria-related information available, particularly on the Internet, and it is scattered among many different sources.

Family planning knowledge, attitudes, and practices of men in Zimbabwe.

The purpose of this report is to describe knowledge, attitudes, and practices in family planning among male Zimbabweans. Understanding the role of men in inhibiting or promoting contraceptive adoption could affect the design of family planning promotion programs and program success in Zimbabwe and other African countries. Data from the 1988 Male Fertility Survey, a representative sample of 711 currently married men aged 20 and over, showed that men have a major role in the decision to use family planning methods and in determining the number of children a couple should have. Male knowledge of various family planning methods was high, as was approval and ever-use of family planning. Attitudes toward family planning information, obtaining methods, couple communication, and family size were also investigated. It was concluded that men should be included in information, education, and communication programs, without delay. Program efforts should move beyond emphasis on child spacing to stress family size limitation in order to increase contraceptive prevalence, resulting in a commensurate decline in the level of fertility.

Family planning information sources and media exposure among Zimbabwean men.

This report describes, for a sample of Zimbabwean men, sources of family planning information, media exposure, media preferences, and whether they would like to learn more about family planning methods. The data are from the 1988 Zimbabwe Male Fertility Survey, a representative sample of 711 currently married men aged 20 and over. The analysis is restricted to the 512 men whose wives were aged 49 and under at the time of the survey. The radio and personal communications, followed by posters and newspapers, are the most frequently reported sources of family planning information. The radio is considered to be the best medium for learning about family planning, followed by community-based distributors. Nearly 85 percent of respondents indicated that they would like to learn more about family planning. Information from men should be included in information, education, and communication programs in order to enhance male involvement in the family planning process.

Stereotype or reality: another look at alcohol and drug use among African American children.

The Center for Substance Abuse Prevention's Division of Communications Programs launched its Urban Youth Public Education Campaign in late 1990 to target African American youth in 14 cities with prevention messages about alcohol and other drugs. During the market research phase of the campaign, the Center sought to determine the extent inner city African American children are impacted by alcohol and other drugs and how widespread the use of these substances is among younger children. Is it rampant and universal, as some press accounts have it, or are the images portrayed by the news media, by popular movies, and by other communication outlets fueling harmful stereotypes? The campaign's market research consisted of in-depth reviews of the literature, of personal communications, conference proceedings, grant and contract reports, monographs, newspaper and magazine articles, and of national survey results, and the analysis of findings from focus groups conducted with 143 African American children living in several urban environments. Although information and conclusions gleaned from the market research revealed a longstanding trend of comparatively lower rates of alcohol and drug use by African American youth, also disclosed was a need for an expanded framework to address the problems of substance abuse within the African American community. An expanded framework acknowledges the dimension of substance use and abuse but also addresses three other dimensions--involvement, exposure, and victimization--that unfold as having major significance for this population of youth who live in urban, high-risk environments.

Global information infrastructure.

The High Performance Computing and Communications Program (HPCC) is a multiagency federal initiative under the leadership of the White House Office of Science and Technology Policy, established by the High Performance Computing Act of 1991. It has been assigned a critical role in supporting the international collaboration essential to science and to health care. Goals of the HPCC are to extend USA leadership in high performance computing and networking technologies; to improve technology transfer for economic competitiveness, education, and national security; and to provide a key part of the foundation for the National Information Infrastructure. The first component of the National Institutes of Health to participate in the HPCC, the National Library of Medicine (NLM), recently issued a solicitation for proposals to address a range of issues, from privacy to 'testbed' networks, 'virtual reality,' and more. These efforts will build upon the NLM's extensive outreach program and other initiatives, including the Unified Medical Language System (UMLS), MEDLARS, and Grateful Med. New Internet search tools are emerging, such as Gopher and 'Knowbots'. Medicine will succeed in developing future intelligent agents to assist in utilizing computer networks. Our ability to serve patients is so often restricted by lack of information and knowledge at the time and place of medical decision-making. The new technologies, properly employed, will also greatly enhance our ability to serve the patient.

Maintaining patient satisfaction in a hospital reorganization.

A review of inpatient satisfaction data for MUSC provides both comfort and cause for additional study. Although overall satisfaction rates of 89 and 88 during the period of organizational change indicate stable patient perceptions, one must reflect upon these scores in greater detail. For example, although survey response rates in the 36 percent to 28 percent range appear customary for this type of survey, absolute numbers of discharge responses averaged 496 for the four quarters reported. Some confidence can be taken in the fact that overall survey scores were highly consistent in the 89 to 88 range for the entire reporting period. Moreover, the fact that workforce performance variables such as medication errors and patient occurrence reports did not change indicates that patient care did not deteriorate during this period. Although one could argue that in a time of workforce reduction, employees may work more diligently in order to ensure job security, and that work deterioration may be more apparent over a longer period of observation, this limited view suggests that, at least in the acute phase, work performance was maintained. Future studies should review the relative effectiveness of the specific strategies adopted by MUSC management to ensure high levels of patient care. For example, although MUSC adopted a fairly comprehensive communications effort, it is difficult to discern whether timeliness, variety, or repetition contributed more to the effectiveness of the communications program. Such information could help managers develop focused change implementation strategies. It appears from the inpatient survey data collected by UHC and from the two work performance monitors that MUSC's approach to change management has been able to preserve acceptable levels of patient satisfaction in the face of significant organizational change. Furthermore, these strategies may have been helpful in countering the turbulence caused by large scale change or, at the very least, insulating the care site from potentially negative effects.

Communication strategies to optimize commitments and investments in iron programming.

There is consensus that a communications component is crucial to the success of iron supplementation and fortification programs. However, in many instances, we have not applied what we know about successful advocacy and program communications to iron programs. Communication must play a larger and more central role in iron programs to overcome several common shortcomings and allow the use of new commitments and investments in iron programming to optimum advantage. One shortcoming is that iron program communication has been driven primarily by the supply side of the supply-demand continuum. That is, technical information has been given without thought for what people want to know or do. To overcome this, the communication component, which should be responsive to the consumer perspective, must be considered at program inception, not enlisted late in the program cycle as a remedy when interventions fail to reach their targets. Another shortcoming is the lack of program focus on behavior. Because the "technology" of iron, a supplement, or fortified or specific local food must be combined with appropriate consumer behavior, it is not enough to promote the technology. The appropriate use of technology must be ensured, and this requires precise and strategically crafted communications. A small number of projects from countries as diverse as Indonesia, Egypt, Nicaragua and Peru offer examples of successful communications efforts and strategies for adaptation by other countries.

Building a medical multimedia database system to integrate clinical information: an application of high-performance computing and communications technology.

The rapid growth of diagnostic-imaging technologies over the past two decades has dramatically increased the amount of nontextual data generated in clinical medicine. The architecture of traditional, text-oriented, clinical information systems has made the integration of digitized clinical images with the patient record problematic. Systems for the classification, retrieval, and integration of clinical images are in their infancy. Recent advances in high-performance computing, imaging, and networking technology now make it technologically and economically feasible to develop an integrated, multimedia, electronic patient record. As part of The National Library of Medicine's Biomedical Applications of High-Performance Computing and Communications program, we plan to develop Image Engine, a prototype microcomputer-based system for the storage, retrieval, integration, and sharing of a wide range of clinically important digital images. Images stored in the Image Engine database will be indexed and organized using the Unified Medical Language System Metathesaurus and will be dynamically linked to data in a text-based, clinical information system. We will evaluate Image Engine by initially implementing it in three clinical domains (oncology, gastroenterology, and clinical pathology) at the University of Pittsburgh Medical Center.

Newborn screening program practices in the United States: notification, research, and consent.

OBJECTIVE: To define current practice among US newborn screening programs for notification of results, research, and consenting procedures. METHODS: A telephone survey of all US newborn screening program supervisors. RESULTS: All 51 programs participated. All states reported abnormal results to the infant's physician, and some also reported to the hospital and parents. Cases with abnormal results were tracked to different endpoints but usually (92.1%) at least until a follow-up appointment was made. A total of 66.6% of programs can communicate with programs in other states; 9.8% enable families to suppress reporting of results to the infant's physician. No state has a mechanism for parents to prevent results from entering the medical record. Parents or physicians who request results are often authenticated by providing their name (52.9%). Many programs (45.1%) report only to physicians and require just their name (43.5%), an identification number (17.4%), a letter (26.1%), or a parent's signature (26.1%). A total of 70.6% retain residual blood samples; of these, only 8.3% store them completely devoid of patient identifiers. A total of 49.0% of programs aggregate data for research. In 16.0% of these, the data are publicly available. In 24.0%, researchers obtain approval at their own institution; in 24.0%, researchers obtain approval through the state laboratory Institutional Review Board. In 74.5% of programs, parents are notified but not asked for consent before collection of the sample; 19.6% neither notify parents nor obtain consent before screening. CONCLUSIONS: There is wide variation in practice among the US newborn screening programs. Because the programs collectively manage a comprehensive nationwide genomic databank, careful consideration of how information technology and high-throughput genomic analysis are used will be essential to allow progress in clinical care, public health, and research while protecting individual privacy.

Telecommunication technology for the management of large scale clinical trials: the Gissi experience.

The Coordinating Centre (CC) of the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto miocardico (GISSI) used telecommunication technology to develop a computerized network system for the data management of the GISSI studies. Through a personal computer (PC), a communication program, a modem and a telephone line, the investigator in each participating centre can connect with a micro-computer at the CC, to recruit/randomize patients and download reports on the progress of the trial. In the first case, the investigator is required to answer a set of predefined questions, and thereby the system automatically checks eligibility criteria and randomly assigns the patient to a treatment arm. In the second case, once the investigator has made a choice from a list of standard reports and the relative query on CC central database, the generation, the formatting and the transfer of the selected report to the PC are executed automatically on line. The main advantages of this system are a reduction in number of mistakes in data completion and in the human and economic resources required, as well as the real time updating of participating centres. The system was successfully adopted in the GISSI-3 trial (200 Coronary Care Units and 19,394 patients enrolled), in the European arm of the CORE trial and it is currently being used in the GISSI-Prevenzione trial.

One size does not fit all: the case for tailoring print materials.

Printed health education materials frequently consist of mass-produced brochures, booklets, or pamphlets designed for a general population audience. Although this one-size-fits-all approach might be appropriate under certain circumstances and even produce small changes at relatively modest costs, it cannot address the unique needs, interests, and concerns of different individuals. With the advent and dissemination of new communication technologies, our ability to collect information from individuals and provide feedback tailored to the specific information collected is not only possible, but practical. The purpose of this article is to: (a) distinguish between tailored print communication and other common communication-based approaches to health education and behavior change; (b) present a theoretical and public health rationale for tailoring health information; and (c) describe the steps involved in creating and delivering tailored print communication programs. Studies suggest computer tailoring is a promising strategy for health education and behavior change. Practitioners and researchers should understand the approach and consider the possibilities it presents for enhancing their work in disease prevention.

Parallel implementations of individual-based models in biology: bulletin- and non-bulletin-board approaches.

Particle-based models are simulations in which the discrete representation of physical phenomenon involves interacting particles. This paper studies the efficiency of two different methods of implementing these models on a network of UNIX workstations. Two data parallel methods of modeling particles are tested: bulletin-board and non-bulletin-board. In the former method, the programs communicate through a logically shared, associative memory called a bulletin-board. The simulated particles are distributed among the workstations dynamically as the processing load on the processors changes. In the latter method, the particles are divided amongst the networked workstations statically at load time. The simulated system is a collection of ants moving and foraging in a two-dimensional space. This paper analyzes and compares the execution times of both implementations for different combinations of particles and number of workstation, using speed-up, tuple granularity and communication cost as measures. Analysis shows that the bulletin-board method is better for particle-based simulations when the correct granularity is chosen.
