Use of diagnostic self-tests on body materials among Internet users in the Netherlands: prevalence and correlates of use

Contains fulltext : 81025.pdf (publisher's version ) (Open Access)BACKGROUND: A range of self-tests on body materials has become available to the general public, but the extent of their use has hardly been studied. This study examined how many people use diagnostic self-tests on body materials such as blood or urine, as well as the type of tests that are used, and factors associated with their use. METHODS: Cross-sectional survey. Participants were recruited from an existing Dutch Internet panel of 12,529 persons, and information was collected by means of a structured Internet-based questionnaire. Multiple logistic regression analyses were used to assess correlates of self-test use. RESULTS: Response to the survey was 63%. Sixteen percent of the respondents said they had ever used at least one self-test, with a mean of 2.1 tests per self-tester. The most frequently reported self-tests were those for diabetes and cholesterol. Self-testers generally reported lower health status and had a higher BMI than non-testers. On the other hand, they were more likely to engage in health-related behaviour such as the use of dietary supplements and homeopathic medicine. CONCLUSION: Self-testing proved to be relatively prevalent among Dutch Internet users. We therefore think that it is essential to develop appropriate information for consumers, health care providers and policymakers, about the pros and cons of self-testing and specific self-tests. More test-specific research is needed

General Characteristics of the Original Articles Included in the Scoping Review on Health and Immigration in Spain

Fundamentos: La realidad socio-demográfica configurada en España a partir de la incorporación de la población inmigrante requiere analizar las necesidades y prioridades generadas por esta situación en todos los ámbitos, incluido el de la investigación en salud. El objetivo del presente estudio es conocer las características generales de los artículos incluidos en una revisión bibliográfica sobre este tema y realizada en el marco del Subprograma de Salud e Inmigración del CIBERESP. Métodos: Revisión bibliográfica de los artículos originales publicados en español o inglés en el periodo 1998-2012. Se seleccionaron artículos realizados en España y que cumplieran la definición de inmigrante de la Organización Internacional de Migraciones. La búsqueda bibliográfica se realizó en Medline y MEDES. Se analizó la distribución temporal de la producción y las características generales de los artículos mediante frecuencias absolutas y relativas. Resultados: En la búsqueda inicial se identificaron 2.625 artículos (2.434 Medline y 191 Medes-MEDicina), finalmente se incluyeron los 311 que cumplían criterios de inclusión. La mayoría eran estudios epidemiológicos de diseño transversal realizados con datos primarios. En el 69% se comparó a la población inmigrante con la autóctona. En 217, (70%) la temática principal fue la relacionada con enfermedades transmisibles. En 256 (82%) el periodo producción fue entre 2004 y 2011. En 220 (71%) el país de origen fue la forma más común de clasificación de la población inmigrante. Conclusiones: Las enfermedades transmisibles fueron el principal objeto de investigación de los estudios desarrollados en España sobre salud de la población inmigrante. La mayoría de estudios incluyen a la población autóctona como grupo de comparación.Background: The new socio-demographic reality that came about with the incorporation of the immigrant population in Spain requires an analysis of the needs and priorities generated by this situation in all areas, including research in health. The objective of this study is to determine the general characteristics of a group of articles included in a literature review on the subject, carried out within the framework of the CIBERSP Subprogram on Migration and Health. Methods: Scoping Review of the literature published in the period 1998-2012.Articles in Spanish or English developed in Spain and that fulfil the definition of immigrant from the International Organization for Migration were selected. The literature search was performed in Medline and MEDES. The temporal distribution of the production and main characteristics of the articles are described trough absolute and relative frequencies. Results: The initial search identified 2.625 articles (Medline 2434; 191 Medes-MEDicina) 311 were including finally. Most epidemiological studies are cross-sectional design with primary data. 69% compared with native population. The main theme has been associated with infectious diseases (n=217, 70%). The period of maximum production is between 2004 and 2011(n=256, 82%). The country of origin is the most common way of classifying immigrants (n=220, 71%). Conclusions: The epidemiology of infectious prevails as the main theme of the studies performed in Spain about the health of the immigrant population. Most of the studies include native population as a comparison group

How do people respond to self-test results? A cross-sectional survey

<p>Abstract</p> <p>Background</p> <p>Self-tests, tests on medical conditions that can be performed by consumers without consulting a doctor first, are frequently used. Nevertheless, there are concerns about the safety of self-testing, as it may delay diagnosis and appropriate treatment in the case of inappropriate use of the test, or false-negative results. It is unclear whether self-tests stimulate appropriate follow-up behaviour. Our aim was to examine the frequency of self-test use, consumers' response to self-test results in terms of their confidence in the result, reassurance by the test result, and follow-up behaviour.</p> <p>Methods</p> <p>A two step cross-sectional survey was designed. A random sample of 6700 Internet users in an existing Internet panel received an online questionnaire on the use of self-tests. Self-tests were defined as tests on body materials, initiated by consumers with the aim to diagnose a disease or risk factor. A second questionnaire on consumers' response to self-test results was sent to the respondents that were identified as a self-tester in the first questionnaire (n = 703).</p> <p>Results</p> <p>18.1% (799/4416) of the respondents had ever performed a self-test, the most frequently used tests being those for diabetes (5.3%), kidney disease (4.9%), cholesterol (4.5%), urinary tract infection (1.9%) and HIV/AIDS and Chlamydia (both 1.6%). A total of 78.1% of the testers with a normal test result and 81.4% of those with an abnormal result reported confidence in this result. Almost all (95.6%) of the testers with a normal result felt reassured. After a normal result, 78.1% did not take any further action and 5.8% consulted a doctor. The corresponding figures after an abnormal test result were 9.3% and 72.2%, respectively.</p> <p>Conclusions</p> <p>Respondents who had performed a self-test seemed to base their follow-up behaviour on the result of the test. They had confidence in the test result, and were often reassured by a normal result. After an abnormal result, most self-testers sought medical care. Because consumers seem to trust the self-test results, further research should focus on the development of consumer information addressing indications for performing a self-test, the validity of self-tests and appropriate interpretation of and management after a test.</p

To test or not to test: A cross-sectional survey of the psychosocial determinants of self-testing for cholesterol, glucose, and HIV

Contains fulltext : 97466.pdf (publisher's version ) (Open Access)BACKGROUND: Although self-tests are increasingly available and widely used, it is not clear whether their use is beneficial to the users, and little is known concerning the determinants of self-test use. The aim of this study was to identify the determinants of self-test use for cholesterol, glucose, and HIV, and to examine whether these are similar across these tests. Self-testing was defined as using in-vitro tests on body materials, initiated by consumers with the aim of diagnosing a particular disorder, condition, or risk factor for disease. METHODS: A cross-sectional Internet survey was conducted among 513 self-testers and 600 non-testers, assessing possible determinants of self-test use. The structured questionnaire was based on the Health Belief Model, Theory of Planned Behavior, and Protection Motivation Theory. Data were analyzed by means of logistic regression. RESULTS: The results revealed that perceived benefits and self-efficacy were significantly associated with self-testing for all three conditions. Other psychosocial determinants, e.g. gender, cues to action, perceived barriers, subjective norm, and moral obligation, seemed to be more test-specific. CONCLUSIONS: Psychosocial determinants of self-testing are not identical for all tests and therefore information about self-testing needs to be tailored to a specific test. The general public should not only be informed about advantages of self-test use but also about the disadvantages. Designers of information about self-testing should address all aspects related to self-testing to stimulate informed decision making which, in turn, will result in more effective self-test use

A single-blind randomised controlled trial of the effects of a web-based decision aid on self-testing for cholesterol and diabetes. study protocol

Background: Self-tests, tests on body materials to detect medical conditions, are widely available to the general public. Self-testing does have advantages as well as disadvantages, and the debate on whether self-testing should be encouraged or rather discouraged is still ongoing. One of the concerns is whether consumers have sufficient knowledge to perform the test and interpret the results. An online decision aid (DA) with information on self-testing in general, and test specific information on cholesterol and diabetes self-testing was developed. The DA aims to provide objective information on these self-tests as well as a decision support tool to weigh the pros and cons of self-testing. The aim of this study is to evaluate the effect of the online decision aid on knowledge on self-testing, informed choice, ambivalence and psychosocial determinants. Methods/Design: A single blind randomised controlled trial in which the online decision aid 'zelftestwijzer' is compared to short, non-interactive information on self-testing in general. The entire trial will be conducted online. Participants will be selected from an existing Internet panel. Consumers who are considering doing a cholesterol or diabetes self-test in the future will be included. Outcome measures will be assessed directly after participants have viewed either the DA or the control condition. Weblog files will be used to record participants' use of the decision aid. Discussion: Self-testing does have important pros and cons, and it is important that consumers base their decision whether they want to do a self-test or not on knowledge and personal values. This study is the first to evaluate the effect of an online decision aid for self-testing

Improving behaviour in self-testing (IBIS): Study on frequency of use, consequences, information needs and use, and quality of currently available consumer information (protocol)

<p>Abstract</p> <p>Background</p> <p>Self-tests are available to consumers for more than 25 conditions, ranging from infectious diseases to cardiovascular risk factors. Self-tests are defined as in-vitro tests on body materials such as blood, urine, faeces, or saliva that are initiated by consumers to diagnose a particular disorder or risk factor without involving a medical professional. In 2006, 16% of a sample of Dutch Internet users had ever used at least one self-test and 17% intended to use a self-test in the future. The objectives of this study are to determine (1) the frequency of self-test use, (2) the consumers' reasons for using or not using a self-test, (3) the information that is used by self-testers in the different self-test stages and the consumers' interpretation of the quality of this information, (4) the consumers' response to self-test results in terms of their confidence in the result, reassurance by the test result, and follow-up behaviour, (5) the information consumers report to need in the decision making process of using or not using a self-test, and in further management on the basis of the self-test result, and (6) the quality of the currently available consumer information on a selected set of self-tests.</p> <p>Methods</p> <p>Mixed methods study with (1) a cross-sectional study consisting of a two-phase Internet-questionnaire, (2) semi-structured interviews with self-testers and consumers who intend to use a self-test, and (3) the assessment of the quality of consumer information of self-tests. The Health Belief Model and the Theory of Planned Behaviour will serve as the theoretical basis for the questionnaires and the interview topic guides.</p> <p>Conclusions</p> <p>The self-testing area is still in a state of flux and therefore it is expected that self-test use will increase in the future. To the best of our knowledge, this is the first study which combines quantitative and qualitative research to identify consumers' information needs and use concerning self-testing, and the consumers' actual follow-up behaviour based on the self-test result, and simultaneously investigates the quality of the currently available consumer information. The results of this study will be used as an input in developing consumer information on self-testing.</p

Impact of primary health care providers’ initial role security and therapeutic commitment on implementing brief interventions in managing risky alcohol consumption: a cluster randomised factorial trial

Background: Brief interventions in primary healthcare to detect and intervene in risky alcohol consumption are cost-effective in reducing drinking problems, but poorly implemented in routine care. Although evidence about implementing brief interventions is growing, knowledge is limited with regard to impact of initial role security and therapeutic commitment on brief intervention implementation.Methods: In a cluster randomised factorial trial 120 Primary Healthcare Units (PHCUs) were randomised to eight groups: care as usual, training and support, financial reimbursement, and the opportunity to refer patients to an internet-based brief intervention (e-BI); paired combinations of these three strategies, and all three strategies combined. To explore the impact of initial role security and therapeutic commitment on implementing brief interventions, we performed multilevel linear regression analyses adapted to the factorial design. Results: Data from 746 providers of 120 PHCUs were included in the analyses. Baseline role security and therapeutic commitment were found not to influence implementation of brief interventions. Furthermore there were no significant interactions between these characteristics and allocated groups. Conclusions: The extent to which providers’ managed to change their brief intervention proportions when submitted to different implementation strategies was not determined by their initial attitudes towards alcohol problems. In future research more attention is needed for the causal relation between these parameters, as it can inform us whether to focus on these or not in implementation trajectories

The ODHIN assessment tool: a tool to describe the available services for the management of hazardous and harmful alcohol consumption at the country and regional level

Optimizing Delivery of Health care Interventions (ODHIN) is an ongoing European project (EC, FP7) involving research institutions from 9 European countries using the implementation of Early Identification and Brief Intervention (EIBI) programmes for Hazardous and Harmful Alcohol Consumption (HHAC) in Primary Health Care (PHC) as a case study to better understand how to translate the results of clinical research into everyday practice. The Italian National Health Service (ISS) is the project leader of the Work Package 6 assessment tool. The aim of the ODHIN assessment tool is to formalise, operationalise and test the questionnaire developed under the PHEPA project in order to produce an update instrument to assess the extent of implementation of EIBIs for HHAC throughout PHC settings. The ODHIN assessment tool has been conceived as a semi-structured questionnaire for the identification of the state of the art, gaps and areas in the country that need further work and strengthening; to monitor the adequacy of brief intervention programmes for HHAC in order to provide recommendations to improve and optimize delivery of health care interventions. It analyses 24 questions distributed across 7 key sections. Data have been collected from 9 ODHIN collaborating countries (Catalonia, Czech Republic, Italy, Poland, Portugal, Slovenia, Sweden, The Netherlands and United Kingdom) and from other 14 European countries who have agreed to share their national experience with the ODHIN partners (Belgium, Croatia, Cyprus, Estonia, Finland, Fyrom-Yugoslav Republic of Macedonia, Germany, Greece, Iceland, Ireland, Latvia, Malta, Romania, and Switzerland). Preliminary data on the state of the art of the implementation and the extent of EIBI for HHAC throughout PHC settings across 23 European participating countries will be presented. Identified areas where services require development or strengthening across the participating countries as well as examples of good practices between countries will be also discussed
