A core outcome set for pre-eclampsia research: an international consensus development study.

OBJECTIVE: To develop a core outcome set for pre-eclampsia. DESIGN: Consensus development study. SETTING: International. POPULATION: Two hundred and eight-one healthcare professionals, 41 researchers and 110 patients, representing 56 countries, participated. METHODS: Modified Delphi method and Modified Nominal Group Technique. RESULTS: A long-list of 116 potential core outcomes was developed by combining the outcomes reported in 79 pre-eclampsia trials with those derived from thematic analysis of 30 in-depth interviews of women with lived experience of pre-eclampsia. Forty-seven consensus outcomes were identified from the Delphi process following which 14 maternal and eight offspring core outcomes were agreed at the consensus development meeting. Maternal core outcomes: death, eclampsia, stroke, cortical blindness, retinal detachment, pulmonary oedema, acute kidney injury, liver haematoma or rupture, abruption, postpartum haemorrhage, raised liver enzymes, low platelets, admission to intensive care required, and intubation and ventilation. Offspring core outcomes: stillbirth, gestational age at delivery, birthweight, small-for-gestational-age, neonatal mortality, seizures, admission to neonatal unit required and respiratory support. CONCLUSIONS: The core outcome set for pre-eclampsia should underpin future randomised trials and systematic reviews. Such implementation should ensure that future research holds the necessary reach and relevance to inform clinical practice, enhance women's care and improve the outcomes of pregnant women and their babies.

Methodological decisions influence the identification of potential core outcomes in studies related to pre-eclampsia: an analysis informing the development of recommendations for future core outcome set developers.

OBJECTIVE: To quantify the effect of different methodological decisions on the identification of potential core outcomes to inform the development of recommendations for future core coutcome set developers. DESIGN: Mixed methods study. SETTING: A core outcome set for pre-eclampsia was used as an exemplar. SAMPLE: A long list of potential core outcomes was developed by undertaking a systematic review of pre-eclampsia trials and performing a thematic analysis of in-depth patient interviews. METHODS: Specific methods used to generate long lists of potential core outcomes were evaluated. RESULTS: Different methodological decisions had a substantial impact on the identification of potential core outcomes. Extracting outcomes from published pre-eclampsia trials was an effective way of identifying 48 maternal, eight fetal, 25 neonatal outcomes, and eight patient-reported outcomes. Limiting the extraction of outcomes to primary outcomes or outcomes commonly reported in pre-eclampsia trials reduced the number and diversity of potential core outcomes identified. Thematic analysis of in-depth patient interviews ensured an additional five patient reported outcomes and six outcomes related to future child health were identified. CONCLUSIONS: Future core outcome set developers should use quantitative and qualitative methods when developing a long list of potential core outcomes. TWEETABLE ABSTRACT: @OfficialNIHR research published in @BJOGtweets informs new recommendations for future @coreoutcomes developers.

What outcomes should researchers select, collect and report in pre-eclampsia research? A qualitative study exploring the views of women with lived experience of pre-eclampsia.

OBJECTIVE: To identify outcomes relevant to women with lived experience of pre-eclampsia. DESIGN: Qualitative interview study. SETTING: A national study conducted in the United Kingdom. SAMPLE: Purposive sample of women with lived experience of pre-eclampsia. METHODS: Thematic analysis of qualitative interview transcripts. RESULTS: Thirty women with lived experience of pre-eclampsia were interviewed. Thematic analysis identified 71 different treatment outcomes. Fifty-nine of these had been previously reported by pre-eclampsia trials. Outcomes related to maternal and neonatal morbidity, commonly reported by pre-eclampsia trials, were frequently discussed by women with lived experience of pre-eclampsia. Twelve outcomes had not been previously reported by pre-eclampsia trials. When compared with published research, it was evident that the outlook of women with lived experience of pre-eclampsia was broader. They considered pre-eclampsia in relation to the 'whole' person and attached special significance to outcomes relating to emotional wellbeing and the future health, development and wellbeing of their offspring. CONCLUSIONS: Selecting, collecting and reporting outcomes relevant to women with pre-eclampsia should ensure that future pre-eclampsia research has the necessary reach and relevance to inform clinical practice. Future core outcome set development studies should use qualitative research methods to ensure that the long list of potential core outcomes holds relevance to patients.

Communication practices for delivering health behaviour change conversations in primary care: a systematic review and thematic synthesis.

BACKGROUND: Clinical guidelines exhort clinicians to encourage patients to improve their health behaviours. However, most offer little support on how to have these conversations in practice. Clinicians fear that health behaviour change talk will create interactional difficulties and discomfort for both clinician and patient. This review aims to identify how healthcare professionals can best communicate with patients about health behaviour change (HBC). METHODS: We included studies which used conversation analysis or discourse analysis to study recorded interactions between healthcare professionals and patients. We followed an aggregative thematic synthesis approach. This involved line-by-line coding of the results and discussion sections of included studies, and the inductive development and hierarchical grouping of descriptive themes. Top-level themes were organised to reflect their conversational positioning. RESULTS: Of the 17,562 studies identified through systematic searching, ten papers were included. Analysis resulted in 10 top-level descriptive themes grouped into three domains: initiating; carrying out; and closing health behaviour change talk. Of three methods of initiation, two facilitated further discussion, and one was associated with outright resistance. Of two methods of conducting behaviour change talk, one was associated with only minimal patient responses. One way of closing was identified, and patients did not seem to respond to this positively. Results demonstrated a series of specific conversational practices which clinicians use when talking about HBC, and how patients respond to these. Our results largely complemented clinical guidelines, providing further detail on how they can best be delivered in practice. However, one recommended practice - linking a patient's health concerns and their health behaviours - was shown to receive variable responses and to often generate resistance displays. CONCLUSIONS: Health behaviour change talk is smoothly initiated, conducted, and terminated by clinicians and this rarely causes interactional difficulty. However, initiating conversations by linking a person's current health concern with their health behaviour can lead to resistance to advice, while other strategies such as capitalising on patient initiated discussions, or collaborating through question-answer sequences, may be well received.

Inadequate safety reporting in pre-eclampsia trials: a systematic evaluation.

BACKGROUND: Randomised trials and their syntheses in meta-analyses offer a unique opportunity to assess the frequency and severity of adverse reactions. OBJECTIVE: To assess safety reporting in pre-eclampsia trials. SEARCH STRATEGY: Systematic search using bibliographic databases, including Cochrane Central Register of Controlled Trials, Embase, and MEDLINE, from inception to August 2017. SELECTION CRITERIA: Randomised trials evaluating anticonvulsant or antihypertensive medication for pre-eclampsia. DATA COLLECTION AND ANALYSIS: Descriptive statistics appraising the adequacy of adverse reaction and toxicity reporting. MAIN RESULTS: We included 60 randomised trials. Six trials (10%) were registered with the International Clinical Trials Registry Platform, two registry records referred to adverse reactions, stating 'safety and toleration' and 'possible side effects' would be collected. Twenty-six trials (43%) stated the frequency of withdrawals within each study arm, and five trials (8%) adequately reported these withdrawals. Adverse reactions were inconsistently reported across eligible trials: 24 (40%) reported no serious adverse reactions and 36 (60%) reported no mild adverse reactions. The methods of definition or measurement of adverse reactions were infrequently reported within published trial reports. CONCLUSIONS: Pre-eclampsia trials regularly omit critical information related to safety. Despite the paucity of reporting, randomised trials collect an enormous amount of safety data. Developing and implementing a minimum data set could help to improve safety reporting, permitting a more balanced assessment of interventions by considering the trade-off between the benefits and harms.

Conducting a team-based multi-sited focused ethnography in primary care.

Focused ethnography is an applied and pragmatic form of ethnography that explores a specific social phenomenon as it occurs in everyday life. Based on the literature a problem-focused research question is formulated before the data collection. The data generation process targets key informants and situations so that relevant results on the pre-defined topic can be obtained within a relatively short time-span. As part of a theory based evaluation of alternative forms of consultation (such as video, phone and email) in primary care we used the focused ethnographic method in a multisite study in general practice across the UK. To date there is a gap in the literature on using focused ethnography in healthcare research.The aim of the paper is to build on the various methodological approaches in health services research by presenting the challenges and benefits we encountered whilst conducing a focused ethnography in British primary care. Our considerations are clustered under three headings: constructing a shared understanding, dividing the tasks within the team, and the functioning of the focused ethnographers within the broader multi-disciplinary team.As a result of using this approach we experienced several advantages, like the ability to collect focused data in several settings simultaneously within in a short time-span. Also, the sharing of experiences and interpretations between the researchers contributed to a more holistic understanding of the research topic. However, mechanisms need to be in place to facilitate and synthesise the observations, guide the analysis, and to ensure that all researchers feel engaged. Reflection, trust and flexibility among the team members were crucial to successfully adopt a team focused ethnographic approach. When used for policy focussed applied healthcare research a team-based multi-sited focused ethnography can uncover practices and understandings that would not be apparent through surveys or interviews alone. If conducted with care, it can provide timely findings within the fast moving context of healthcare policy and research.

Core outcome sets in women's and newborn health: a systematic review.

BACKGROUND: Variation in outcome collection and reporting is a serious hindrance to progress in our specialty; therefore, over 80 journals have come together to support the development, dissemination, and implementation of core outcome sets. OBJECTIVE: This study systematically reviewed and characterised registered, progressing, or completed core outcome sets relevant to women's and newborn health. SEARCH STRATEGY: Systematic search using the Core Outcome Measures in Effectiveness Trial initiative and the Core Outcomes in Women's and Newborn Health initiative databases. SELECTION CRITERIA: Registry entries, protocols, systematic reviews, and core outcome sets. DATA COLLECTION AND ANALYSIS: Descriptive statistics to describe characteristics and results. RESULTS: There were 49 core outcome sets registered in maternal and newborn health, with the majority registered in 2015 (n = 22; 48%) or 2016 (n = 16; 32%). Benign gynaecology (n = 8; 16%) and newborn health (n = 3; 6%) are currently under-represented. Twenty-four (52%) core outcome sets were funded by international (n = 1; <1%), national (n = 18; 38%), and regional (n = 4; 8%) bodies. Seven protocols were published. Twenty systematic reviews have characterised the inconsistency in outcome reporting across a broad range of relevant healthcare conditions. Four core outcome sets were completed: reconstructive breast surgery (11 outcomes), preterm birth (13 outcomes), epilepsy in pregnancy (29 outcomes), and maternity care (48 outcomes). The quantitative, qualitative, and consensus methods used to develop core outcome sets varied considerably. CONCLUSIONS: Core outcome sets are currently being developed across women's and newborn health, although coverage of topics is variable. Development of further infrastructure to develop, disseminate, and implement core outcome sets is urgently required. TWEETABLE ABSTRACT: Forty-nine women's and newborn core outcome sets registered. 50% funded. 7 protocols, 20 systematic reviews, and 4 core outcome sets published. @coreoutcomes @jamesmnduffy.

Outcome reporting across randomised controlled trials evaluating therapeutic interventions for pre-eclampsia.

BACKGROUND: Standardising outcome collection and reporting in pre-eclampsia trials requires an appraisal of current outcome reporting. OBJECTIVES: To map maternal and offspring outcome reporting across randomised trials evaluating therapeutic interventions for pre-eclampsia. SEARCH STRATEGY: Randomised trials were identified by searching bibliographical databases from inception to January 2016. SELECTION CRITERIA: Randomised controlled trials. DATA COLLECTION AND ANALYSIS: We systematically extracted and categorised outcome reporting. MAIN RESULTS: Seventy-nine randomised trials, reporting data from 31 615 maternal participants and 28 172 of their offspring, were included. Fifty-five different interventions were evaluated. Included trials reported 119 different outcomes, including 72 maternal outcomes and 47 offspring outcomes. Maternal outcomes were inconsistently reported across included trials; for example, 11 trials (14%) reported maternal mortality, reporting data from 12 422 participants, and 16 trials (20%) reported cardiovascular morbidity, reporting data from 14 963 maternal participants. Forty-three trials (54%) reported fetal outcomes and 23 trials (29%) reported neonatal outcomes. Twenty-eight trials (35%) reported offspring mortality. There was poor reporting of childhood outcomes: six trials (8%) reported neurodevelopmental outcomes. Less than half of included trials reported any relevant information regarding harms for maternal participants and their offspring. CONCLUSIONS: Most randomised trials evaluating interventions for pre-eclampsia are missing information on clinically important outcomes, and in particular have neglected to evaluate efficacy and safety in the offspring of participants. Developing and implementing a minimum data set, known as a core outcome set, in future pre-eclampsia trials could help to address these issues.

Incurable, invisible and inconclusive: watchful waiting for chronic lymphocytic leukaemia and implications for doctor-patient communication.

Patients with chronic lymphocytic leukaemia (CLL) find it hard to accept a diagnosis of an incurable cancer for which no treatment is recommended and which may not cause symptoms for many years. We used qualitative interviews with 12 people with CLL managed by watchful waiting, drawn from a maximum variation sample of 39 adults with leukaemia, to explore accounts of watchful waiting and implications for clinical management. Patients with CLL recalled being given little information about the condition and wanted to know more about how it might affect them in the future. The invisibility of CLL meant that some chose not to disclose the diagnosis to others. Check-ups sometimes felt cursory, causing dissatisfaction. As symptoms increased, lifestyle adaptations became essential, well before treatment was warranted. Patients with CLL on watchful waiting experience levels of depression, anxiety and quality of life similar to those in active treatment; our qualitative approach has illuminated some of the reasons for the negative psychological impacts. We relate our findings to perceptions of the illness state, doctor-patient communication, and work pressure. We recommend that specialists could better support patients by acknowledging psychological impacts of CLL, actively listening to patients' concerns, and meeting their needs for information.

Perceptions and experiences of blood pressure self-monitoring during hypertensive pregnancy: A qualitative analysis of women's and clinicians' experiences in the OPTIMUM-BP trial.

BACKGROUND: Self-monitoring of blood pressure (BP) has been shown to be effective at improving BP control in the general population. The OPTIMUM-BP feasibility study was a prospective randomised controlled trial of self-monitoring of BP (SMBP) during hypertensive pregnancy. OBJECTIVE: To explore experiences, perceptions, and use of the OPTIMUM-BP self-monitoring intervention. STUDY DESIGN: Qualitative study within the OPTIMUM-BP feasibility trial. Semi-structured interviews with a purposive sample of pregnant women with chronic hypertension (n = 24) and their clinicians (n = 8) as well as 38 ethnographic observations of antenatal visits. RESULTS: Women found self-monitoring of BP feasible and acceptable and were highly motivated and pro-active in their monitoring, reporting greater control and knowledge of BP and reassurance. Women's persistence with SMBP was driven by a perceived need to safeguard the pregnancy, particularly among those taking antihypertensive medication. Clinicians also described the intervention as acceptable, though BP variability could cause uncertainty. Clinicians used different heuristics to integrate home and clinic readings. Observations suggested close working relationships between women and clinicians were key for confident integration of self-monitoring. CONCLUSIONS: Self-monitoring of BP was acceptable both to pregnant women with hypertension and their clinicians. More research is needed to understand BP variability within pregnancy to help interpret and integrate home BP readings for improved BP management. Clinical pathways that use BP self-monitoring should aim to maintain the continuity of care and relationships that are valued and appear pivotal for the confident and safe use of self-monitoring in pregnancy.

Factors contributing to the time taken to consult with symptoms of lung cancer: a cross-sectional study.

OBJECTIVES: To determine what factors are associated with the time people take to consult with symptoms of lung cancer, with a focus on those from rural and socially deprived areas. METHODS: A cross-sectional quantitative interview survey was performed of 360 patients with newly diagnosed primary lung cancer in three Scottish hospitals (two in Glasgow, one in NE Scotland). Supplementary data were obtained from medical case notes. The main outcome measures were the number of days from (1) the date participant defined first symptom until date of presentation to a medical practitioner; and (2) the date of earliest symptom from a symptom checklist (derived from clinical guidelines) until date of presentation to a medical practitioner. RESULTS: 179 participants (50%) had symptoms for more than 14 weeks before presenting to a medical practitioner (median 99 days; interquartile range 31-381). 270 participants (75%) had unrecognised symptoms of lung cancer. There were no significant differences in time taken to consult with symptoms of lung cancer between rural and/or deprived participants compared with urban and/or affluent participants. Factors independently associated with increased time before consulting about symptoms were living alone, a history of chronic obstructive pulmonary disease (COPD) and longer pack years of smoking. Haemoptysis, new onset of shortness of breath, cough and loss of appetite were significantly associated with earlier consulting, as were a history of chest infection and renal failure. CONCLUSION: For many people with lung cancer, regardless of location and socioeconomic status, the time between symptom onset and consultation was long enough to plausibly affect prognosis. Long-term smokers, those with COPD and/or those living alone are at particular risk of taking longer to consult with symptoms of lung cancer and practitioners should be alert to this.

The short form 36 health status questionnaire: clues from the Oxford region's normative data about its usefulness in measuring health gain in population surveys.

OBJECTIVES: To determine the potential of the short form 36 health status questionnaire (SF-36) for indicating changes in the health status of a general population by examining the recently published normative data. DESIGN: The sensitivity of the SF-36 was tested through hypothesising two dramatic changes in health status whereby (i) the scores of people in social class V are improved to the level of social class I, and (ii) the scores of men and women aged 55 to 64 are altered to the level of current 45 to 54 year olds. The size of the effect measured by the SF-36 was considered. RESULTS: Small to moderate effects were evident when SF-36 mean scores for social class V were increased to the level of social class I, and primarily negligible effects were apparent on all domains but physical function for the postulated "10 years of age" improvement. CONCLUSION: The SF-36 may be a useful measure for detecting changes in health status in homogenous treatment groups, but the variation in responses in a general population make it an inadequate tool for assessing the diffuse impact of health interventions directed at the whole community.

Emergency contraception: an anomalous position in the family planning repertoire?

Emergency contraception (EC) can be used up to 72 h after sex to prevent pregnancy. Internationally there is wide variation in the availability of EC. In the USA it has only recently (1997) won approval from the FDA, while the UK and New Zealand have seen calls for over the counter availability. In recent years surveys, editorials and opinion pieces in medical journals have pointed out that increased access to EC could help to tackle the unwanted pregnancy rate, especially among teenagers, and concluded that lack of knowledge of EC is the major barrier to use. However, women in a UK study have expressed concerns that it is not safe to use the method repeatedly and cited general practitioners (GPs) as one of the sources of this belief, which contradicts the professional guidelines and the rationale for de-regulation. A subsequent study sought to seek the views of GPs about prescribing EC and explored reasons for the gap between the views of women using UK family planning services, GPs and professionals at the public policy level. Data from two studies are presented. In the first study, 53 women seeking emergency contraception were interviewed at two family planning clinics. In the second, semi-structured telephone interviews were completed with a random sample of 76 GPs from three English health authorities. Interviews were recorded, transcribed and thematic analysis was conducted using the constant comparative method. EC was rarely described, by users or GPs, as an acceptable contraceptive option. Consultations for emergency contraception were viewed by GPs as an important opportunity to discuss the woman's future contraceptive needs. Repeated use of EC was not encouraged and a discussion of contraceptive needs could range from a mild enquiry to quite forceful messages contrasting EC to 'regular' and 'proper' methods. The medical literature suggests that EC is underused because of a lack of awareness. Commentators have recommended educating health professionals and women about EC and increasing availability through de-regulation. The data presented in this paper show that British GPs are not enthusiastic about the de-regulation of EC, but the reasons are complex and related to concerns about planned contraception and sexual behaviour. It is suggested that it may be because EC is used after sex that it seems to occupy an uncomfortable place within the contraceptive repertoire.

Tacit models of disability underlying health status instruments.

In recent years much attention has been paid to the development of measures of subjective health status yet, although statistical criteria of reliability and validity have been quite rigourously tested, there has been little consideration of the different theories of disability which underlie the design. The sociology of disability may illuminate such tacit theories. It is suggested that the development of health status questionnaires has not been one of simple rational accumulation in response to methodological advances. Through an examination of the content of health assessment questionnaires, four distinct models of disability are identified. These are shown to influence not only the focus of the content and phrasing of the questions but also, crucially, the way that they perform and how responsive they are to change. The models (the functional, subjective distress, comparative and dependence) are illustrated and discussed in terms related to research design.

Lack of willpower or lack of wherewithal? "Internal" and "external" barriers to changing diet and exercise in a three year follow-up of participants in a health check.

The aims of this paper were to assess whether anticipated barriers to change in diet and exercise which were cited before a health check intervention were related to subsequent behaviour changes. In 1989 a health and lifestyle questionnaire was posted to 17,965 people aged 35-64 who were registered with five general practices in Bedfordshire. Taking account of non-contacts, a response rate of 80.3% was achieved and 11,090 people described their exercise and dietary habits. Those expressing an interest in changing each behaviour were asked to identify reasons why change might be difficult. Two types of barriers--"internal" and "external"--were identified. A total of 2205 respondents were invited to attend a health check in Year One and a recheck three years later and 1660 attended. In this subgroup improvement in exercise and diet was examined in relation to the participants' baseline characteristics, including the type of barriers selected. Internal barriers to change (e.g. lack of willpower, too lazy, too busy) were chosen most frequently. In a logistic regression including a range of baseline variables those who selected only internal barriers were less likely to take more exercise (OR 0.59, 95% CI 0.41, 0.86) than those who cited only external (e.g. no transport, can't afford sports facilities) or mixed barriers to changing. There was a similar but not statistically significant trend for changing diet (OR 0.78, 95% CI 0.48, 1.28). Those who are aware of external limitations may be better placed to circumvent them. Further research is needed to explore this relationship between type of barrier and behaviour change.

Not a 'proper' solution? The gap between professional guidelines and users' views about the safety of using emergency contraception.

OBJECTIVES: As a form of contraception which is used after sex, emergency contraception occupies a singular place in the birth control repertoire. The relatively high UK incidence of pregnancy terminations and of teenage pregnancy, combined with the recognition that much early sex remains unplanned and unprotected, has led to calls for better access to emergency contraceptive methods. In this study a combination of self-completion questionnaires and semi-structured interviews was used to explore views of emergency contraception among women who were using the method. METHODS: Five hundred and ten women attending two family planning clinics in Oxford and London completed a questionnaire in the waiting room and 53 women who were attending for emergency contraception took part in semi-structured interviews. RESULTS: The view, presented in recently published UK guidelines, that emergency contraception is a reliable method and not dangerous to repeat, was not shared by the respondents. The rationale for and sources of women's concerns about the strength of the dose of hormonal emergency contraception and the nature of side-effects are explored.

Importance of sensitivity to change as a criterion for selecting health status measures.

OBJECTIVE: To assess the sensitivity to change over time of four health status instruments in relation to patients with rheumatoid arthritis. DESIGN: Observational three month study of four self assessed instruments (arthritis impact measurement scales (AIMS), health assessment questionnaire (HAQ), Nottingham health profile (NHP), functional limitations profile (FLP)). SETTING: One rheumatology unit. PATIENTS: 101 patients with definite or classic rheumatoid arthritis. MAIN MEASURES: Change scores for dimensions of instruments, as determined by effect size (mean change in score/baseline standard deviation of variable) and conventional rheumatological measures, at baseline and after three months. RESULTS: Change scores for comparable dimensions (mobility, activities of daily living, household, pain, mood or emotion, and social scales) of the instruments were compared among 30 patients who considered their health status to have improved over three months. For all dimensions of health status the magnitude of change varied considerably according to the instrument. Maximum range in effect size was for social scales (AIMS 0.06, NHP 0.24, FLP 0.60). No single instrument seemed consistently to show the most change over all dimensions. CONCLUSION: Selection of health status instruments for audit or evaluation may have a considerable impact on the pattern of results obtained, and the "responsiveness" of such scales should be as carefully examined as their reliability and acceptability when selecting outcome measures.

Smoking cessation interventions for dental patients--attitudes and reported practices of dentists in the Oxford region.

OBJECTIVE: To investigate various aspects of dentists' beliefs and practices with respect to helping their patients stop smoking. DESIGN: Postal questionnaire survey conducted in 1996. SETTING: The general dental practitioners on the health authority lists of Berkshire, Buckinghamshire, Northamptonshire and Oxfordshire. SUBJECTS: The 869 dentists registered on 1 April 1996. RESULTS: A high response rate (78%; 674/869) was obtained. The majority of respondents (82%; 95% CI: 79, 85) thought dentists should encourage their patients to stop smoking although only 37% (95% CI: 34, 41) believed dentists to be effective in smoking cessation and even fewer (18%; 95% CI: 15, 21) routinely recorded their patients' smoking status. Of respondents, 51% (95% CI: 46, 55) said they always discussed smoking with patients who had periodontal problems but only 9% (95% CI: 7, 12) always did so with patients who had no major oral health problem. Newer graduates were more likely to routinely record their patients' smoking status (P = 0.02), and to think that doctors' advice (P = 0.001) and nicotine replacement therapy (P < 0.001) were effective in promoting smoking cessation. Dentists in mainly private practices were more active than those in NHS or mixed practices in recording patients' smoking status (P < 0.001) and in discussing smoking (P = 0.002). CONCLUSIONS: Most respondents thought that dentists should encourage their patients to stop smoking but few are active in this area.

Computer support for recording and interpreting family histories of breast and ovarian cancer in primary care (RAGs): qualitative evaluation with simulated patients.

OBJECTIVES: To explore general practitioners' attitudes towards and use of a computer program for assessing genetic risk of cancer in primary care. DESIGN: Qualitative analysis of semistructured interviews and video recordings of simulated consultations. PARTICIPANTS: Purposive sample of 15 general practitioners covering a range of computer literacy, interest in genetics, age, and sex. INTERVENTIONS: Each doctor used the program in two consultations in which an actor played a woman concerned about her family history of cancer. Consultations were videotaped and followed by interviews with the video as a prompt to questioning. MAIN OUTCOME MESURESs: Use of computer program in the Consultation. RESULTS: The program was viewed as an appropriate application of information technology because of the complexity of cancer genetics and a sense of "guideline chaos" in primary care. Doctors found the program easy to use, but it often affected their control of the consultation. They needed to balance their desire to share the computer screen with the patient, driven by their concerns about the effect of the computer on doctor-patient communication, against the risk of premature disclosure of bad news. CONCLUSIONS: This computer program could provide the necessary support to assist assessment of genetic risk of cancer in primary care. The potential impact of computer software on the consultation should not be underestimated. This study highlights the need for careful evaluation when developing medical information systems.

'A mastectomy for something that wasn't even truly invasive cancer'. Women's understandings of having a mastectomy for screen-detected DCIS: a qualitative study.

OBJECTIVES: To explore women's understandings of having a mastectomy for screen-detected ductal carcinoma in situ (DCIS). SETTING: Participants recruited throughout the United Kingdom and interviewed in their own homes by an anthropologist. METHODS: Qualitative study using semi-structured interviews and thematic analysis. Thirty-five women with screen-detected DCIS were interviewed, of whom twenty had a mastectomy. RESULTS: A qualitative thematic analysis of women's understandings of having a mastectomy for DCIS identified four key themes: understandings of routine breast screening; uncertainty about DCIS and its natural progression; uncertainty about whether a mastectomy is justified for DCIS; information gaps and treatment decisions. Women were often concerned that a mastectomy for screen-detected DCIS was a 'drastic' treatment for an asymptomatic, precancerous condition of which they had been previously unaware. Some questioned why they were treated with such urgency, even suspecting that their clinicians were responding to targets. CONCLUSION: Given the uncertainties about DCIS and its complexity, it is important that women have the information they need to make treatment decisions. Better information about the uncertainties and the rationale for using mastectomy as a treatment may help women to make better informed choices and feel more comfortable about their decisions.
