Variation in health care--the roles of the electronic medical record.

Variation in the use of clinical resources, outcomes, costs, access to health care and quality is a well recognized, ever present feature of health care. It is a phenomenon that affects all sectors of the health care delivery process and is important to clinicians, administrators and patients. As a phenomenon variation can be appropriate or inappropriate and the elimination of inappropriate variation is a fundamental principal behind continuous quality improvement in health care. The primary tools for the management of variation exists within the electronic medical record (EMR). The EMR utilizes the existing and evolving information storage technologies (data repositories) and information management tools (applications), to integrate the elements within this long-term data storage. Through this integration the EMR systems are able to provide knowledge representation in differing formats to the decision-makers and this will facilitate more accurate and appropriate decision-making with subsequent improvements in health care delivery.

Statistical and study design issues in assessing the quality and outcomes of care in rheumatic diseases.

As we have pointed out in this article, a health care study should have a well-defined intent that is matched to the study type, population of interest, and outcome. Care must be taken to collect samples in a meaningful way, so that results can be generalized to larger populations. Outcomes must be selected carefully to ensure that they will be sensitive to the types of care being considered, and only a few main outcomes should be selected so as to preserve the level of statistical significance of the research results. Sample sizes should be sufficient to detect an effect of reasonable size, after accounting for attrition in longitudinal studies and rates of occurrence with dichotomous outcomes. If the study purpose is to compare multiple institutions or health care providers, statistical adjustments for case mix will generally be required. Outcome research is an expanding area of development for rheumatology care and for medical care in general. It offers the promise of the use of administrative data bases to answer questions that are important both to arthritis researchers and to consumers of rheumatology care. As with all areas of clinical research, we must maintain appropriate levels of statistical rigor to protect the integrity of the results. Inadequate attention to the design and analysis of data can compromise research results before a study even gets started, and health care research studies have as many potential statistical pitfalls as other types of clinical research.

Primary care, private physicians, and public health personnel: a conflict in expectations.

The elimination of categorical grants and their replacement by block grants provides public health departments the opportunity to integrate their services and provide general primary care to the underserved. While some may consider this an opportunity long overdue such a change may generate considerable conflict with private physicians. Questionnaire data from private physicians and health department personnel collected in North Carolina during an experimental program of primary care delivery by health department shows that there is substantial conflict. Private physicians oppose health department involvement in general primary care and in acute ambulatory care for the medically underserved. Physicians expect health departments to focus on preventive services, especially environmental monitoring and communicable disease control. Health department personnel want to expand their efforts beyond these more traditional areas into primary care and are in apparent conflict with private physicians. The community attitudes of a group of physicians within a community as well as the attitudes of a group of public health workers were found to be a major determinant of each individual's attitude toward public health, followed by the individual's age, sex, and years of working in the community.

[Cocaine abuse in Vienna and European cities--a multi-center study].

INTRODUCTION: As cocaine consumption seems to have increased over the last decades, the EU has funded this multi-center, cross-sectional survey to investigate cocaine consumption in three different target groups. The study was conducted by the Addiction Clinic, Department of Psychiatry, Medical University Vienna and other nine European cities. METHODS: Data were collected by structured face-to-face interviews. The sample was composed of 211 cocaine abusers out of three target groups: (1) treatment group undergoing opioid maintenance therapy, (2) marginalized scene group and (3) integrated party group. Sociodemographic data such as age, education, employment, monthly expenses on cocaine/crack, data on consumption patterns, physical and mental health and personal needs regarding cocaine consumption were evaluated. Urine toxicology results for cocaine in the treatment group completed the analysis. RESULTS: The marginalized scene group was the oldest with a mean age of 29.35 years, with the highest unemployment rate (mean 25.11 days) and the longest duration of cocaine consumption (mean 5.80 years). They had the highest cocaine consumption pattern with a mean of 22.32 days within the last month. On average 1969 Euros/months was spent for their addiction. The treatment group had the lowest school education with a mean of 10.36 years, but showed a sufficient insight in their cocaine problem. However, the party group (with the lowest mean age, 25.64 years) highly underestimated their drug problem, the mean amount of money they spent for their addiction was 588.99 Euro/months. Structured urine toxicology between 1996 and 2002 in patients undergoing opioid maintenance therapy ("treatment group") revealed a significant increase of concomitant cocaine consumption (1996: 33.1%; 2002: 40.2%; p = 0.044). DISCUSSION: The European trend of increased cocaine use could also be observed in Vienna. One of the greatest barriers for establishing adequate treatment settings for this target group is the difficulty to reach this population. In addition, multiple substance abuse seems to be one of the predominating patterns of cocaine consumption and this aspect should be integrated within treatment (in the treatment and scene groups additional heroin and benzodiapzepines abuse is observed, in the party group intensive alcohol consumption). The Viennese results are in line with those of the other European cities; however, it could not be confirmed that consumption of crack cocaine and binge play a similarly significant role as in cities such as Hamburg or London.

Integrated care networks and quality of life: linking research and practice.

PURPOSE: To report on the development of a project dedicated to improving the quality of life of older people through the creation of integrated networks. CONTEXT: The project is set within a post-industrial community and against a backdrop of government re-organisation and devolution within Wales. The immediate research context is determined by utilising an approach to the structure of integration derived theoretically. CASE DESCRIPTION: Project CHAIN (Community Health Alliances through Integrated Networks) adopts a network perspective as a means of addressing both the determinants of health and service delivery in health and social care. The Project partners are: healthcare commissioners and providers; local authority directorates including community services and transportation; the voluntary and private sectors; and a university institute. Co-opted participants include for a representing older people's interests. DATA SOURCES: The Project incorporates an action research method. This paper highlights qualitative data elicited from interviews with health and social care managers and practitioners. CONCLUSIONS AND DISCUSSION: The Project is ongoing and we record progress in building five integrated networks.

Health expectancy and the problem of substitute morbidity.

During the past century, the developed world has not only witnessed a dramatic increase in life expectancy (ageing), but also a concomitant rise in chronic disease and disability. Consequently, the tension between 'living longer' on the one hand and health-related 'quality of life' on the other has become an increasingly important health policy problem. The paper deals with two consequences of this so-called epidemiological transition in population health. The first one concerns the question of how--given the impressive changes--population health can be measured in an adequate and policy relevant present-day fashion. The second one is the so-called phenomenon of 'substitute morbidity and mortality': more and more acute fatal diseases are replaced by non-fatal delayed degenerative diseases like dementia and arthritis. How the phenomenon of substitute morbidity and mortality affects the development of population health is illustrated with the epidemiological transitions, worldwide shifts in the main causes of death, assumptions used in models, adverse consequences of medical technologies and some results from intervention trials. Substitute morbidity and mortality may thwart our disease-specific expectations of interventions and asks for a shift to a 'total population health' perspective when judging potential health gains of interventions. Better understanding of the dynamics that underly the changes in population health is necessary. Implications for data collections are more emphasis on morbidity data and their relation with mortality, more longitudinal studies, stricter requirements for intervention trials and more use of modelling as a tool. A final recommendation is the promotion of integrative measures of population health. For the latter several results are presented suggesting that, although the amount of morbidity and disability is growing with an increasing life expectancy, this is mild unhealthiness in particular. This finding supports the 'dynamic equilibrium' theory. In absolute numbers, however, the burden of disease will continue to increase with further ageing of the population.

Dynamic linear model and SARIMA: a comparison of their forecasting performance in epidemiology.

One goal of a public health surveillance system is to provide a reliable forecast of epidemiological time series. This paper describes a study that used data collected through a national public health surveillance system in the United States to evaluate and compare the performances of a seasonal autoregressive integrated moving average (SARIMA) and a dynamic linear model (DLM) for estimating case occurrence of two notifiable diseases. The comparison uses reported cases of malaria and hepatitis A from January 1980 to June 1995 for the United States. The residuals for both predictor models show that they were adequate tools for use in epidemiological surveillance. Qualitative aspects were considered for both models to improve the comparison of their usefulness in public health. Our comparison found that the two forecasting modelling techniques (SARIMA and DLM) are comparable when long historical data are available (at least 52 reporting periods). However, the DLM approach has some advantages, such as being more easily applied to different types of time series and not requiring a new cycle of identification and modelling when new data become available.

Mapping water quality and substrate cover in optically complex coastal and reef waters: an integrated approach.

Sustainable management of coastal and coral reef environments requires regular collection of accurate information on recognized ecosystem health indicators. Satellite image data and derived maps of water column and substrate biophysical properties provide an opportunity to develop baseline mapping and monitoring programs for coastal and coral reef ecosystem health indicators. A significant challenge for satellite image data in coastal and coral reef water bodies is the mixture of both clear and turbid waters. A new approach is presented in this paper to enable production of water quality and substrate cover type maps, linked to a field based coastal ecosystem health indicator monitoring program, for use in turbid to clear coastal and coral reef waters. An optimized optical domain method was applied to map selected water quality (Secchi depth, Kd PAR, tripton, CDOM) and substrate cover type (seagrass, algae, sand) parameters. The approach is demonstrated using commercially available Landsat 7 Enhanced Thematic Mapper image data over a coastal embayment exhibiting the range of substrate cover types and water quality conditions commonly found in sub-tropical and tropical coastal environments. Spatially extensive and quantitative maps of selected water quality and substrate cover parameters were produced for the study site. These map products were refined by interactions with management agencies to suit the information requirements of their monitoring and management programs.

Integrating core information competencies into a traditional curriculum: a collaborative approach.

To prepare for a career, in which they keep up-to-date with current physical therapy procedures and health care trends, it is imperative that students become life-long learners. Four core competencies have been identified as skills to promote life-long learning: e-mail, professional electronic mailing lists (listservs), online data-base searching, and searching the World Wide Web. This paper discusses integrating the core competencies into the curriculum of a physical therapist assistant program through a collaborative effort between the physical therapist assistant program faculty and librarians.
