Non-invasive prenatal testing for aneuploidy: a systematic review of Internet advertising to potential users by commercial companies and private health providers.

BACKGROUND: The development of non-invasive prenatal testing has increased accessibility of fetal testing. Companies are now advertising prenatal testing for aneuploidy via the Internet. OBJECTIVES: The aim of this systematic review of websites advertising non-invasive prenatal testing for aneuploidy was to explore the nature of the information being provided to potential users. METHODS: We systematically searched two Internet search engines for relevant websites using the following terms: 'prenatal test', 'antenatal test', 'non-invasive test', 'noninvasive test', 'cell-free fetal DNA', 'cffDNA', 'Down syndrome test' or 'trisomy test'. We examined the first 200 websites identified through each search. Relevant web-based text was examined, and key topics were identified, tabulated and counted. To analyse the text further, we used thematic analysis. MAIN RESULTS: Forty websites were identified. Whilst a number of sites provided balanced, accurate information, in the majority supporting evidence was not provided to underpin the information and there was inadequate information on the need for an invasive test to definitely diagnose aneuploidy. CONCLUSIONS: The information provided on many websites does not comply with professional recommendations. Guidelines are needed to ensure that companies offering prenatal testing via the Internet provide accurate and comprehensible information.

Guidance for patients considering direct-to-consumer genetic testing and health professionals involved in their care: development of a practical decision tool.

BACKGROUND: Direct-to-consumer (DTC) genetic tests are available online, but there is little practical guidance for health professionals and consumers concerning their use. Work to produce such guidance was initially informed by three systematic reviews assessing the evidence on views and experiences of users and health professionals and policies of professional and bioethics organizations. The evidence suggested that consumers' motivations include general curiosity, improving their general health, ascertaining the risk of a particular condition or planning for future children. However, health professionals and bioethics organizations expressed concerns about potential harms resulting from these tests. Using this evidence, we constructed a list of topics to be included in proposed guidelines. METHODS: Using an expert group technique, we aimed to develop guidance for (i) potential consumers and (ii) health professionals approached by patients considering or having undertaken such tests. We considered it important to involve a wide range of participants with relevant experience. Accordingly, researchers and clinicians based in four countries were invited to a 2-day workshop in August 2012. Following an iterative process, we decided to produce clinically relevant and pragmatic guidance in the form of a decision support tool for use in primary care. RESULTS: By utilizing both the relevant literature and the experience of the expert group, we identified seven key underlying reasons that might prompt individuals to consider DTC testing. We considered primary care physicians as the most likely health professionals from whom individuals would seek advice. CONCLUSIONS: Based on the outcomes of the workshop, we developed a decision support tool encompassing varied clinical scenarios. Health professionals and patients are guided through a pathway that includes relevant actions and information on the appropriateness of the test. This tool will be freely accessible to health professionals and patients online.

Can I get a retweet please? Health research recruitment and the Twittersphere.

AIM: To evaluate the social networking site Twitter™ as a vehicle for recruitment in online health research and to examine how the Twitter community would share information: the focus of our study was the antenatal experience of mothers of advanced maternal age. BACKGROUND: One result of growth in worldwide Internet and mobile phone usage is the increased ability to source health information online and to use social media sites including Facebook and Twitter. Although social media have been used in previous health research, there is a lack of literature on the use of Twitter in health research. DESIGN: A cross-sectional survey. METHOD: We report a novel recruitment method via a social networking site between May and August 2012. Through a Twitter account, we tweeted and requested other Twitter users to retweet our invitation to be involved in the study. Tweets contained a unique URL directing participants to an online survey hosted on the Survey Monkey™ website. FINDINGS: Over 11 weeks, 749 original tweets were posted by the researcher. A total of 529 mothers accessed the survey as a result of 359 researcher tweets and subsequent retweets that were seen by Twitter users. The survey was fully completed by 299 (56·5%) participants. CONCLUSION: Twitter is a cost-effective means of recruitment, enabling engagement with potentially difficult-to-reach populations, providing participants with transparency, anonymity and a more accessible method by which to participate in health research.

Recruitment to online therapies for depression: pilot cluster randomized controlled trial.

BACKGROUND: Raising awareness of online cognitive behavioral therapy (CBT) could benefit many people with depression, but we do not know how purchasing online advertising compares to placing free links from relevant local websites in increasing uptake. OBJECTIVE: To pilot a cluster randomized controlled trial (RCT) comparing purchase of Google AdWords with placing free website links in raising awareness of online CBT resources for depression in order to better understand research design issues. METHODS: We compared two online interventions with a control without intervention. The pilot RCT had 4 arms, each with 4 British postcode areas: (A) geographically targeted AdWords, (B) adverts placed on local websites by contacting website owners and requesting links be added, (C) both interventions, (D) control. Participants were directed to our research project website linking to two freely available online CBT resource sites (Moodgym and Living Life To The Full (LLTTF)) and two other depression support sites. We used data from (1) AdWords, (2) Google Analytics for our project website and for LLTTF, and (3) research project website. We compared two outcomes: (1) numbers with depression accessing the research project website, and then chose an onward link to one of the two CBT websites, and (2) numbers registering with LLTTF. We documented costs, and explored intervention and assessment methods to make general recommendations to inform researchers aiming to use similar methodologies in future studies. RESULTS: Trying to place local website links appeared much less cost effective than AdWords and although may prove useful for service delivery, was not worth pursuing in the context of the current study design. Our AdWords intervention was effective in recruiting people to the project website but our location targeting "leaked" and was not as geographically specific as claimed. The impact on online CBT was also diluted by offering participants other choices of destinations. Measuring the impact on LLTTF use was difficult as the total number using LLTTF was less than 5% of all users and record linkage across websites was impossible. Confounding activity may have resulted in some increase in registrations in the control arm. CONCLUSIONS: Practitioners should consider online advertising to increase uptake of online therapy but need to check its additional value. A cluster RCT using location targeted adverts is feasible and this research design provides the best evidence of cost-effectiveness. Although our British pilot study is limited to online CBT for depression, a cluster RCT with similar design would be appropriate for other online treatments and countries and our recommendations may apply. They include ways of dealing with possible contamination (buffer zones and AdWords techniques), confounding factors (large number of clusters), advertising dose (in proportion to total number of users), record linkage (landing within target website), and length of study (4-6 months).

Informed consent for blood tests in people with a learning disability.

AIM: This article is a report of a study of informed consent in people with a learning disability. The aims of the study were to explore the information needs of people with mild-to-moderate learning disabilities with respect to consent for blood tests and to identify ways of facilitating informed consent. BACKGROUND: The recent political agenda for social change in the UK has emphasized the right of people with a learning disability to have more autonomy and make their own decisions. As in other countries, there has also been a shift towards shared decision-making in healthcare practice. DESIGN: Qualitative study using an ethnographic approach. METHODS: An ethnographic approach was used for this qualitative study. Phase 1 involved observation of six participants with a learning disability having a routine blood test in general practice, followed by semi-structured interviews with 14 participants with a learning disability in Phase 2. Data were collected between February 2009-February 2010. FINDINGS: The data showed that consent procedures were often inadequate and provision of information to patients prior to a blood test was variable. People with a learning disability expressed clearly their information requirements when having a routine blood test; this included not wanting any information in some cases. CONCLUSIONS: Healthcare practitioners and people with a learning disability need to be familiar with current consent law in their own country to facilitate valid consent in the healthcare context. This study demonstrated the value of qualitative research in exploring the knowledge and attitudes of people with learning disability.

Genetics: advocating for the rights of all individuals to informed decision making and voluntary action.

This is the fourth article in a series describing how nurses can develop their confidence and competence in genetics and genomics health care. The focus of this article is the right of the individual to make an informed choice, to be supported to make that choice and to do so in a voluntary manner. Nurses are well placed to support patients who may be considering genetic testing and are often responsible for gaining their consent for such investigations. It is essential that they provide balanced information in a way that the patient can understand and are able to explain the different options and possible outcomes of genetic tests, while considering the wider implications this may have on the patient's family.

Incidental findings in genetic research and clinical diagnostic tests: a systematic review.

Incidental findings arise when clinically relevant genetic information about a research participant or patient is identified outside the scope of the original research objective or diagnostic test being performed. These findings can relate to carrier status for a heritable condition, misattributed paternity or increased susceptibility to a medical condition. The decision whether to disclose these findings to the research subject or patient is underpinned by many ethical, moral, and potentially legal considerations. There is an urgent need for definitive guidelines for researchers and healthcare professionals. We performed a systematic review of the relevant literature concerning the disclosure of incidental findings, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations, using the prescribed flowchart and checklist. At initial screening, 473 articles were retrieved. The inclusion and exclusion criteria aimed at obtaining data that were relevant and of sufficient quality were applied and a total of four relevant studies were identified, comprising 2,680 individual participants and 1,023 guidance documents. Major themes emerging from the included articles include patient autonomy, patient welfare, harmful secrets, and genetic literacy. The lack of relevant studies emphasizes the urgent need for empirical investigations into the disclosure or non-disclosure of genetic incidental findings, and the provision of guidelines to assist healthcare professionals and researchers.

Accuracy of geographically targeted internet advertisements on Google AdWords for recruitment in a randomized trial.

BACKGROUND: Google AdWords are increasingly used to recruit people into research studies and clinical services. They offer the potential to recruit from targeted control areas in cluster randomized controlled trials (RCTs), but little is known about the feasibility of accurately targeting ads by location and comparing with control areas. OBJECTIVE: To examine the accuracy and contamination of control areas by a location-targeted online intervention using Google AdWords in a pilot cluster RCT. METHODS: Based on previous use of online cognitive behavioral therapy for depression and population size, we purposively selected 16 of the 121 British postcode areas and randomized them to three intervention and one (do-nothing) control arms. Two intervention arms included use of location-targeted AdWords, and we compared these with the do-nothing control arm. We did not raise the visibility of our research website to normal Web searches. Users who clicked on the ad were directed to our project website, which collected the computer Internet protocol (IP) address, date, and time. Visitors were asked for their postcode area and to complete the Patient Health Questionnaire (depression). They were then offered links to several online depression resources. Google Analytics largely uses IP methods to estimate location, but AdWords uses additional information. We compared locations assessed by (1) Analytics, and (2) as self-identified by users. RESULTS: Ads were shown 300,523 times with 4207 click-throughs. There were few site visits except through AdWord click-throughs. Both methods of location assessment agreed there was little contamination of control areas. According to Analytics, 69.75% (2617/3752) of participants were in intervention areas, only 0% (8/3752) in control areas, but 30.04% (1127/3752) in other areas. However, according to user-stated postcodes, only 20.7% (463/2237) were in intervention areas, 1% (22/2236) in control areas, but 78.31% (1751/2236) in other areas. Both location assessments suggested most leakage from the intervention arms was to nearby postcode areas. Analytics data differed from postcodes reported by participants. Analysis of a subset of 200/2236 records over 10 days comparing IP-estimated location with stated postcode suggested that Google AdWords targeted correctly in just half the cases. Analytics agreed with our assessment that, overall, one-third were wrongly targeted by AdWords. There appeared little evidence that people who bothered to give their postcode did not answer truthfully. CONCLUSIONS: Although there is likely to be substantial leakage from the targeted areas, if intervention and control areas are a sufficient distance apart, it is feasible to conduct a cluster RCT using online ads to target British postcode areas without significant contamination.

Informed consent to healthcare interventions in people with learning disabilities--an integrative review.

AIM: This paper is a report of an integrative review of informed consent to healthcare interventions in people with learning disabilities. BACKGROUND: Consent to treatment lies at the heart of the relationship between patient and healthcare professional. In order for people with learning disabilities to have equity of access to health care, they need to be able to give informed consent to health interventions--or be assessed as incompetent to give consent. DATA SOURCES: The British Nursing Index (BNI), CINAHL, MEDLINE, Social Care Online, ERIC and ASSIA and PsycINFO databases were searched using the search terms: Consent or informed choice or capacity or consent to treat* or consent to examin* AND Learning disab* or intellectual* disab* or mental* retard* or learning difficult* or mental* handicap*. The search was limited to papers published in English from January 1990 to March 2007. REVIEW METHODS: An integrative review was conducted and the data analysed thematically. RESULTS: Twenty-two studies were reviewed. The main themes identified were: life experience, interaction between healthcare professionals and participants, ability to consent, and psychometric variables. A consensus seemed to emerge that capacity to consent is greater in people with higher cognitive ability and verbal skills, but that the attitudes and behaviour of healthcare professionals was also a crucial factor. CONCLUSION: The findings support use of the functional approach to assessing mental capacity for the purpose of obtaining informed consent. Future research into informed consent in people with learning disabilities is needed using real life situations rather than hypothetical vignettes.

Impact of fetal or child loss on parents' perceptions of non-invasive prenatal diagnosis for autosomal recessive conditions.

OBJECTIVE: to explore parents' personal attitudes towards non-invasive prenatal diagnosis in the context of their own experiences caring for a child affected with a genetic condition or after the loss of a fetus, infant, or child due to the condition. METHODS: we collected in-depth data from parents via either focus groups or individual interviews. DESIGN: this was a cross-sectional interpretive study based on grounded theory. SETTING: United Kingdom. PARTICIPANTS: 17 parents (13 women and four men) who were carriers of a serious autosomal recessive condition: spinal muscular atrophy, cystic fibrosis or thalassaemia. All had a child (living or deceased) with the condition. FINDINGS: parents experienced changes in reproductive self-identity due to their experiences of having an affected child: this influenced their views of non-invasive prenatal testing. They began their reproductive journeys 'naively', but described feelings of reproductive vulnerability after the diagnosis of the child and consequent realisation of risks to future children. They viewed non-invasive prenatal testing as a way to reduce threats to unborn children, while allowing prenatal diagnosis. KEY CONCLUSIONS: when parents lose a child they may use emotional guarding, delayed pregnancy disclosure and avoidance of harmful activities to cope in future pregnancies. Parents who want to consider early prenatal testing are less able to utilise these strategies, but non-invasive methods allow them to reduce the risk. IMPLICATIONS FOR PRACTICE: midwives should be sensitive to parents' reproductive vulnerability after genetic diagnosis of a child and ensure they are supported to consider the option of non-invasive prenatal testing if appropriate.

The evidence base regarding the experiences of and attitudes to preimplantation genetic diagnosis in prospective parents.

BAACKGROUND: Preimplantation genetic diagnosis was developed as an alternative to prenatal diagnosis for couples with a family history of genetic disease. After in vitro fertilization, the embryos can be analysed to ensure that only healthy embryos are transferred to the uterus. Past studies have suggested that couples who wish to avoid having a child with an inherited genetic condition look favourably on preimplantation genetic diagnosis as it prevents the need for termination of pregnancy following prenatal diagnosis of an affected fetus. However, it is important to understand the experiences of couples who have used or consider using this technique. METHODS: To ascertain the current evidence base on this topic, we conducted a mixed methods systematic review. Four databases were searched for relevant peer-reviewed papers published between 2000 and 2013. Of 453 papers, nine satisfied the inclusion criteria and were assessed for quality. Results of nine papers were analysed and synthesised using a narrative approach. FINDINGS: Three main themes emerged: (1) motivating factors; (2) emotional labour; (3) choices and uncertainty. The review has identified an emotional and difficult journey for couples pursuing preimplantation genetic diagnosis. While use of the technique gives hope to families who wish to prevent transmission of a genetic disease this is not without hard decision-making and periods of uncertainty. Lack of information was perceived as a barrier to access this reproductive option. IMPLICATIONS FOR PRACTICE: Recommendations include: training and education in genetics for midwives who are the first point of contact for pregnant women; clinics to use a decision-making tool to emphasise the uncertainty involved in PGD and improved communication and psychological support to couples.

An easy test but a hard decision: ethical issues concerning non-invasive prenatal testing for autosomal recessive disorders.

Prenatal testing based on cell-free fetal DNA in maternal serum is now possible for specific monogenic conditions, and studies have shown that the use of non-invasive testing is supported by prospective parents and health professionals. However, some ethical issues have been raised concerning informed consent and paternal rights. The objective of this study was to explore ethical aspects of the use of non-invasive prenatal diagnostic testing for autosomal recessive disorders. We used a qualitative cross-sectional design, based on Thematic Analysis, and recruited 27 individuals of reproductive age who were carriers of one of four conditions: thalassaemia, sickle cell disease, cystic fibrosis or spinal muscular atrophy. Data were collected via focus groups or interviews. Participants were aware of the potential for such tests to be viewed as routine and suggested that obtaining written consent and allowing time for consideration is needed to facilitate autonomous choice and informed consent. All participants felt that mothers should be able to request such tests, but fathers who declined carrier testing should be made aware that fetal test results may reveal their status. We suggest that a written record of consent for non-invasive prenatal diagnosis should be used as a standard to help reinforce the serious nature of the test results. Where the father's carrier status could be revealed through fetal testing, he should be made aware of this before the results are available. Health professionals should discuss with the pregnant woman the best way to manage unsought information about the father's carrier status to minimise family disruption.

Offering prenatal diagnostic tests: European guidelines for clinical practice [corrected].

For over four decades, it has been possible to offer prenatal diagnostic testing for fetal abnormalities. Prenatal testing is now available for a wide range of monogenic disorders as well as chromosomal abnormalities and should be provided within the ethical framework of informed consent and autonomous choice. However, there are no published guidelines for health professionals from varied disciplines who offer prenatal diagnosis (PND) in a range of possible settings including departments of maternity, obstetrics and clinical genetics. We used an Expert Group technique to develop a set of guidelines for provision of prenatal diagnostic services. Thirteen European health professionals, all experts in PND, participated in a workshop to develop the guidelines, which were then subjected to a wide consultation process. The objective of PND was defined as providing prenatal diagnostic testing services (for genetic conditions) that enable families to make informed choices consistent with their individual needs and values and which support them in dealing with the outcome of such testing. General principles, logistical considerations, clinical care and counselling topics are all described and are equally applicable to invasive and non-invasive testing. These guidelines provide a framework for ethical clinical care; however, they are flexible enough to enable practitioners to adapt them to their particular setting. Ideally, an individualised approach to each family is required to ensure autonomous choice and informed consent regarding prenatal diagnostic testing within the local ethical and legal framework.

Are health professionals ready for direct-to-consumer genetic and genomic testing?

Direct-to-consumer genetic and genomic tests have been offered for over a decade. With the reduction in the cost of sequencing, the options for consumers will increase, with subsequent pressure on health services to interpret data and integrate the results into healthcare management. However, indications are that health professionals are grossly unprepared to deal with requests for support from those who have undertaken direct-to-consumer genetic or genomic tests. While benefits may be derived from patient-driven investigations, distinction needs to be made between the mostly uncertain clinical utility of susceptibility testing and the potential benefits of a reliably interpreted sequencing result. It is essential that we develop strategies, including enhanced professional education, to cope with the potential impact on the health services, rather than ignoring these developments. There may also be implications for the future of genetic counseling, with potential changes in the current paradigm.

Quality in genetic counselling for presymptomatic testing--clinical guidelines for practice across the range of genetic conditions.

Presymptomatic testing (PST) is the performance of a genetic test on an asymptomatic individual at risk of a condition to determine whether the person has inherited the disease-causing mutation. Although relevant guidelines exist for specific diseases, there is no overarching protocol that can be adapted to any disorder or clinical setting in which such testing is offered. The objective of this European project was to develop a set of coherent guidelines for PST (for adult-onset monogenic conditions) for use by health professionals working in a range of disciplines, countries or contexts. To ensure the guidelines were appropriate and practice based, we organised a workshop attended by an expert group of practitioners with relevant health professional backgrounds from 11 countries. Models of service for offering PST were presented, the group then discussed different aspects of testing and the standard of care required to ensure that patients were prepared to make decisions and deal with results and consequences. After the workshop, several rounds of consultation were used with a wider group of professionals to refine the guidelines. The guidelines include general principles governing the offer of testing (eg, autonomous choice of the patient), objectives of genetic counselling in this context (eg, facilitation of decision making), logistical considerations (eg, use of trained staff) and topics to be included during counselling discussion with the patient (eg, consequences of both positive and negative outcomes). We recommend the adoption of these guidelines to provide an equitable structure for those seeking PST in any country.

Direct-to-consumer genomic testing from the perspective of the health professional: a systematic review of the literature.

Since the 1990s, there has been a rapid expansion in the number and type of genetic tests available via health professionals; the last 10 years, however, have seen certain types of genetic and genomic tests available direct-to-consumer. The aim of this systematic review was to explore the topic of direct-to-consumer genetic testing from the health professional perspective. Search terms used to identify studies were 'direct-to-consumer', personal genom*, health* professional*, physician* 'genomic, genetic' in five bibliographic databases, together with citation searching. Eight quantitative papers were reviewed. Findings indicate a low level of awareness and experience of direct-to-consumer testing in health professionals. Inconsistent levels of knowledge and understanding were also found with two studies showing significant effects for gender and age. Concerns about clinical utility and lack of counselling were identified. Health professionals specialising in genetics were most likely to express concerns. There was also evidence of perceived increased workload for health professionals post-testing. However, some health professionals rated such tests clinically useful and cited benefits such as the increased opportunity for early screening. Despite limited awareness, knowledge and experience of actual cases, we concluded that the concerns and potential benefits expressed may be warranted. It may be useful to explore the attitudes and experiences of health professionals in more depth using a qualitative approach. Finally, it is essential that health professionals receive sufficient education and guidelines to equip them to help patients presenting with the results of these tests.

Direct-to-consumer genomic testing: systematic review of the literature on user perspectives.

Genetic tests have traditionally been offered by health professionals. However, genomic tests have been available direct to the consumer for the last decade, increasingly via the Internet. The aim of this systematic review was to ascertain the evidence concerning use of direct-to-consumer genomic testing from the consumer perspective. Primary research was identified using the search terms 'direct-to-consumer' and 'genomic or genetic' in six bibliographic databases and citation searching of findings. In all, 17 papers were reviewed: 3 qualitative and 14 quantitative. Findings indicate a low level of awareness of direct-to-consumer genomic testing and, because of the hypothetical nature of many studies, little evidence from users of such tests. Although potential users appear to be interested in information about their risks of developing common diseases, concerns were expressed about privacy of genetic risk information and the reliability of genomic tests. Consumers were anxious about the nature of the results. There appeared to be a preference to access genomic tests via a health professional, or to discuss the results and obtain advice from a health professional. Authors of only two papers recruited participants who had used direct-to-consumer tests and samples from the large quantitative studies were not representative of the population. These factors limit the value of the available evidence. However, we conclude that there is public interest in direct-to-consumer genomic tests, and that this is likely to result in an increased workload for a range of health professionals. We also consider that there are educational implications for both consumers and health professionals.

Genomic medicine: what are the challenges for the National Health Service?

'Personalized medicine' is inextricably linked with current advances in genomics. Although initial claims about the power of genomic tests have been modified, they have the potential to inform a personalized approach to healthcare. Within the health service, genomic testing is being applied in specific situations to inform therapy; however, more robust studies are needed to identify those tests that can make significant improvements to management and prevention of disease. Despite efforts to educate health professionals, genetic literacy remains unsatisfactory and more efforts are needed to embed genetics in pre- and post-registration professional education, and therefore, maximize benefit for patients. Primary care and public health professionals may be contexts in which genomics can be utilized for both personalized healthcare and promotion of community health.

Do adverts increase the probability of finding online cognitive behavioural therapy for depression? Cross-sectional study.

OBJECTIVE: To estimate the effect of online adverts on the probability of finding online cognitive behavioural therapy (CBT) for depression. DESIGN: Exploratory online cross-sectional study of search experience of people in the UK with depression in 2011. (1) The authors identified the search terms over 6 months entered by users who subsequently clicked on the advert for online help for depression. (2) A panel of volunteers across the UK recorded websites presented by normal Google search for the term 'depression'. (iii) The authors examined these websites to estimate probabilities of knowledgeable and naive internet users finding online CBT and the improved probability by addition of a Google advert. PARTICIPANTS: (1) 3868 internet users entering search terms related to depression into Google. (2) Panel, recruited online, of 12 UK participants with an interest in depression. MAIN OUTCOME MEASURES: Probability of finding online CBT for depression with/without an advert. RESULTS: The 3868 users entered 1748 different search terms but the single keyword 'depression' resulted in two-thirds of the presentations of, and over half the 'clicks' on, the advert. In total, 14 different websites were presented to our panel in the first page of Google results for 'depression'. Four of the 14 websites had links enabling access to online CBT in three clicks for knowledgeable users. Extending this approach to the 10 most frequent search terms, the authors estimated probabilities of finding online CBT as 0.29 for knowledgeable users and 0.006 for naive users, making it unlikely CBT would be found. Adding adverts that linked directly to online CBT increased the probabilities to 0.31 (knowledgeable) and 0.02 (naive). CONCLUSIONS: In this case, online CBT was not easy to find and online adverts substantially increased the chance for naive users. Others could use this approach to explore additional impact before committing to long-term Google AdWords advertising budgets. TRIAL REGISTRATION: This exploratory case study was a substudy within a cluster randomised trial, registered on http://www.clinicaltrials.gov (reference: NCT01469689). (The trial will be reported subsequently).

Interventions to improve rates of post-mortem examination after stillbirth.

OBJECTIVE: Despite recognition of the value of post-mortem examination following stillbirth, worldwide rates have declined since the early 1990s. There is a paucity of published evidence relating to factors that can improve post-mortem uptake. The aim of this study was to assess post-mortem rates following stillbirth and identify trends in the past 18 years that may have affected acceptance of the investigation. STUDY DESIGN: Retrospective cohort study. RESULTS: Sharp declines in post-mortems coincided with publicity surrounding unlawful organ retention. Although nationally post-mortem rates have continued to fall, in our unit there was recovery in post-mortem rates. This increase was associated with implementation of policies to promote the uptake of perinatal post-mortem, including availability of specialist perinatal pathologists, education in the value of post-mortem, and senior staff involvement in counselling regarding the procedure. CONCLUSION: The need to improve uptake of post-mortem examination following stillbirth is internationally recognized. The results of this study suggest that increased local availability of specialist perinatal pathologists, who can support education in the value of post-mortem, along with senior staff obtaining consent, may help achieve this goal.
