Self-testing for cancer: a community survey

A patient focused relationship for specialists in laboratory medicine

Technological change is driving individualized healthcare delivery including laboratory medicine. Ensuring patients gain from their empowerment it is essential that they access data that enables them to utilize reliable information. The potential difficulties of comprehension, information retention and imperfect modes of communication can significantly impair utilization of information by patients. Support for understanding and decision-making needs to be clinically competent and integrated within the healthcare team. Specialists in laboratory medicine are well placed to undertake such a role, the issues around this are explored and proposals for better direct engagement with patients made.

Predictors of genetic testing decisions: a systematic review and critique of the literature

Genetic testing is increasingly available in medical settings and direct-to-consumer. However, the large and growing literature on genetic testing decisions is rife with conflicting findings, inconsistent methodology, and uneven attention across test types and across predictors of genetic testing decisions. Existing reviews of the literature draw broad conclusions but sacrifice nuanced analysis that with a closer look reveals far more inconsistency than homogeny across studies. The goals of this paper are to provide a systematic review of the empirical work on predictors of genetic testing decisions, highlight areas of consistency and inconsistency, and suggest productive directions for future research. We included all studies that provided quantitative analysis of subjective (e.g., perceived risk, perceived benefits of testing) and/or objective (e.g., family history, sociodemographic variables) predictors of genetic testing interest, intentions, or uptake, which produced a sample of 115 studies. From this review, we conclude that self-reported and test-related (as opposed to disorder-related or objective) predictors are relatively consistent across studies but that theoretically-driven efforts to examine testing interest across test types are sorely needed.

Home diagnostic tests in the state of Qatar: a snapshot of public views, level of awareness and use

BACKGROUND

In Qatar, home diagnostic tests are available over the counter in community pharmacies. While possibly beneficial, these tests have the potential for harm if they are used in the absence of pharmacist counseling.

OBJECTIVES

To determine the public views, level of awareness and use of home diagnostic tests and to evaluate the extent of community pharmacists' involvement in educating the public about these tests in Qatar.

SETTING

Qatar's Supreme Council of Health lists 245 community pharmacies in Qatar. Ten community pharmacies were randomly selected from the list as study sites.

METHOD

The investigators visited selected pharmacies on different weekdays and at different times of the day. Members of the public who appeared to be over 16 years of age and able to communicate in English or Arabic were randomly approached, provided with the study objectives, and requested to participate. Those who offered oral consent were anonymously interviewed using a multipart survey.

MAIN OUTCOME MEASURES

Measures include the public awareness and use of home diagnostic tests and the extent of community pharmacist involvement in educating the public about these tests.

RESULTS

During the 5-month study period, 297 patients answered the survey (60 % response rate). Most respondents were aware of at least one home diagnostic test (98 %). The top four home diagnostic tests that the respondents had ever heard of included: thermometers (91 %), blood pressure monitors (91 %), blood sugar tests (86 %) and regular pregnancy tests (72 %). Seventy-one percent of respondents had performed at least one home diagnostic test. When asked about the factors that influenced their choice of the home diagnostic tests, the pharmacist was only cited by 7 % of respondents. The majority of respondents (>80 %) agreed that using a home diagnostic test is convenient, comfortable and helps them in early diagnosis and treatment of healthcare conditions. Only 31 % agreed that the pharmacist offered sufficient information on what to do in case the test result turns to be positive. The study results suggest that generally, the public has good attitudes and awareness of home diagnostic tests. However, the results indicate that Qatar community pharmacists are not sufficiently involved in public education about home diagnostic tests. Pharmacists should take a more active role in counseling the public on the proper use of these tests.

'Do it yourself' sexual health care: the user experience

OBJECTIVES

To describe client experience of self-management within a busy walk-in, sexual health service. Self-management in this context is self-registration and take-home pregnancy tests, chlamydia (Chlamydia trachomatis) and gonorrhoea (Neisseria gonorrhoeae) tests, or condoms dispensed from a free vending machine.

METHODS

Twenty-four in-depth, semi-structured interviews with users; 19 structured written reports from mystery shoppers paid to visit the service and report their experience; demographic details of those using the self-management option from the clinic database and 40 h of recorded observation in the clinic waiting room.

RESULTS

Between 2 September 2008 and 1 September 2009, 18 657 people had 28 545 attendances at the service. Of these, 1845 (6.5%) attendances were self-managed by 1555 individuals (8.3% of all clients). Of those who self-managed, 646 (35%) obtained a chlamydia and gonorrhoea test only, 597 (32%) obtained condoms only and 488 (27%) obtained a pregnancy test only. Users valued the opportunity to self-manage because of the reduced waiting times, autonomy and privacy that such a service offers. Some prefer the additional support offered within a clinical consultation. Users made personalised decisions about self-management based on time pressure, need for additional services and preferred source of support. Users often required help and advice from client support workers to complete the self-management process. This created problems with confidentiality.

CONCLUSIONS

Self-management is an acceptable option within sexual health services if informal support is available. Self-management options in clinical services could mean that 8% of clients at 6% of visits do not need to see a clinician, thus freeing up clinical capacity.

Why members of the public self-test: an interview study

BACKGROUND

A wide range of self-tests are available where contact with a health professional is not necessary.

OBJECTIVE

To investigate factors that influenced members of the public to use self-tests.

METHODS

Questionnaires, sent to 2335 adults from two general practices in North Birmingham, asked whether recipients had used self-tests and sought consent for contacting them about taking part in an interview. Twenty-three people were interviewed, 20 of whom had used self-tests. The interviews were transcribed verbatim, and a thematic analysis was conducted.

RESULTS

The findings were organized around two themes. 'Motivations for self-testing' describes the motivating factors surrounding participants' choices to use self-tests. This appeared to be influenced by a number of factors that were organized into four sub-themes: 'diagnosis or speculation', 'perceived benefits of self-testing', 'general attitudes to and experiences of health care' and 'general attitudes to health'. The second theme called 'experience of self-testing' describes participants' access to, and use of self-tests, and is split into three sub-themes: 'opportunistic awareness and access', 'use and application' and 'impact on life'.

CONCLUSIONS

Overall, self-testing encompasses a broad variety of beliefs and experiences. Some participants saw self-tests as a serious diagnostic tool, whereas others used them out of simple curiosity. Some were motivated by their generally positive attitude to health, but others may have been motivated by negative health care experiences. Some saw self-testing as an empowering process to be proud of, while others seemed to view it as an illegitimate activity that needed to be hidden from professionals.

Prevalence of the use of self-tests by adults in the United Kingdom: a questionnaire survey

BACKGROUND

Self-tests that people can do without a health professional are widely available, but there is little information about how many people have used one. Our aim was to describe the prevalence of use.

METHODS

An initial questionnaire, sent to 8048 adults registered with six general practices in North Birmingham and Warwickshire and Worcestershire, asked whether the person had self-tested. A second questionnaire validated the use for people from the final four practices by asking how each self-test had been obtained and why it had been used.

RESULTS

The age-standardised prevalence of confirmed use for any self-test other than for pregnancy or high blood pressure was 47 (95% confidence interval (CI): 37-57) per 1000 women and 22 (95% CI: 14-30) per 1000 men. If everyone who initially reported use but did not return an eligible second questionnaire had the same rates of confirmed use as eligible responders, this would increase to 95 (95% CI: 81-110) per 1000 women and 55 (95% CI: 41-68) per 1000 men.

CONCLUSION

An appreciable minority of the population have self-tested for medical conditions.

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

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.

Factors associated with self-care activities among adults in the United Kingdom: a systematic review

Background

The Government has promoted self-care. Our aim was to review evidence about who uses self-tests and other self-care activities (over-the-counter medicine, private sector, complementary and alternative medicine (CAM), home blood pressure monitors).

Methods

During April 2007, relevant bibliographic databases (Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Applied Social Sciences Index and Abstracts, PsycINFO, British Nursing Index, Allied and Complementary Medicine Database, Sociological Abstracts, International Bibliography of the Social Sciences, Arthritis and Complementary Medicine Database, Complementary and Alternative Medicine and Pain Database) were searched, and potentially relevant studies were reviewed against eligibility criteria. Studies were included if they were published during the last 15 years and identified factors, reasons or characteristics associated with a relevant activity among UK adults. Two independent reviewers used proformas to assess the quality of eligible studies.

Results

206 potentially relevant papers were identified, 157 were excluded, and 49 papers related to 46 studies were included: 37 studies were, or used data from questionnaire surveys, 36 had quality scores of five or more out of 10, and 27 were about CAM. Available evidence suggests that users of CAM and over-the-counter medicine are female, middle-aged, affluent and/or educated with some measure of poor health, and that people who use the private sector are affluent and/or educated.

Conclusion

People who engage in these activities are likely to be affluent. Targeted promotion may, therefore, be needed to ensure that use is equitable. People who use some activities also appear to have poorer measures of health than non-users or people attending conventional services. It is, therefore, also important to ensure that self-care is not used as a second choice for people who have not had their needs met by conventional services.
