Randomised controlled trials (RCTs) represent the gold standard methodology for determining effectiveness of healthcare interventions. Poor recruitment to RCTs can threaten external validity and waste resources. An inherent tension exists between safeguarding informed decision-making by participants and maximising numbers enrolled. This study investigated what occurs during informed consent appointments in an ongoing multi-centre RCT in the UK. Objectives were to investigate: 1] how study staff presented study information to participants; 2] what evidence emerged as to how well-informed participants were when proceeding to randomisation or treatment selection; and 3] what aspects of the communication process may facilitate improvements in providing evidence of informed consent. Qualitative analysis of a purposive sample of 23 recruitment appointments from three study centres and involving several recruitment staff applied techniques of thematic, content and conversation analysis (CA). Thematic analysis and CA revealed variation in appointment content and structure. Appointments were mostly recruiter-led or participant-led, and this structure was associated with what evidence emerged as to how participants understood information provided and whether they were in equipoise. Participant-led appointments provided this evidence more consistently. Detailed CA identified communication techniques which, when employed by recruiters, provided evidence as to how participants understood the choices before them. Strategic use of open questions, pauses and ceding the floor in the interaction facilitated detailed and systematic exploration of each participant’s concerns and position regarding equipoise. We conclude that the current focus on content to be provided to achieve informed consent should be broadened to encompass consideration of how information is best conveyed to potential participants. A model of tailored information provision using the communication techniques identified and centred on eliciting and addressing participants’ concerns is proposed. Use of these techniques is necessary to make potential participants’ understanding of key issues and their position regarding equipoise explicit in order to facilitate truly informed consent.

Introduction The randomised controlled trial (RCT) is accepted as the gold standard methodology for evaluating effectiveness of healthcare interventions. However, low accrual threatens the power of RCTs, external validity of findings, and may necessitate additional investment of research resources (Britton et al., 1998). Maximising recruitment is therefore crucial. Barriers to recruitment may be clinician-related (perceived lack of resources, time constraints, loss of professional autonomy and concern about impact on doctor– patient relationships) or patient-related (difficulties with informed

consent, uncertainty, or preferences for particular treatments, Mills et al., 2006; Ross et al., 1999). RCTs can only be undertaken where there is ‘equipoise’: that is, there is no evidence to show that a person would be advantaged or disadvantaged by being allocated to a particular treatment (Chard & Lilford, 1998; Freedman, 1987). Ethically potential recruits must be given sufficient information to make an informed decision about participation (ICH, 1996; World Medical Association, 2004). In practice, they should be fully informed, in equipoise and accept randomisation to determine treatment (Bower, King, Nazareth, Lampe, & Sibbald, 2005; Mills et al., 2003). This raises questions as to what level of detail of information is required for a person to give informed consent, and when and how it should be provided (Boulton & Parker, 2007). Current practices leave room for improvement: in one RCT 51% of participants believed the doctor

J. Wade et al. / Social Science & Medicine 68 (2009) 2018–2028

had chosen their treatment and only 23% knew they had been randomised (Hietanen, Aro, Holli, & Absetz, 2000). Participants frequently fail to understand the rationale for RCTs (Featherstone & Donovan, 1998, 2002; Robinson et al., 2004). A systematic review, attempting to identify optimal methods of obtaining informed consent showed that providing more information led to greater understanding of the nature of RCTs and rights to withdraw or choose treatment but lower consent rates (Edwards, Lilford, are Thornton, & Hewison, 1998). While content and presentation of written participant information sheets (PIS) are highly standardised (Grossman, Piantadosi, & Cohavey, 1994; NRES, 2005), the content and quantity of spoken information provided in informed consent appointments are not monitored and their effects on participant understanding are unknown (Brown, Butow, Butt, Moore, & Tattersall, 2004). Providing an accurate PIS is not enough to ensure comprehension of key issues (Dixon-Woods et al., 2007). Potential participants need time to discuss and understand concepts of randomisation and equipoise (Featherstone & Donovan, 1998; Jenkins, Fallowfield, Shouhami, & Sawtell, 1999; Mills et al., 2003). A small number of studies have audio- or video-taped informed consent appointments. These found recruiters were poor at initiating discussions of the participant’s perspective (Brown, Butow, Ellis, Boyle, & Tattersall, 2004; Tomamichel et al., 1995), checking participant comprehension of information (Brown, Butow, Ellis, et al., 2004; Jenkins et al., 1999; Tomamichel et al., 1995) and explaining key concepts such as randomisation and equipoise (Albrecht, Blanchard, Ruckdeschel, Coovert, & Strongbow, 1999; Brown, Butow, Ellis, et al., 2004; Donovan et al., 2002; Jenkins et al., 1999). Brown, Butow, Butt, et al. (2004) proposed a typology to evaluate the content and quality of information given by oncologists seeking informed consent for clinical trials. They proposed a) strategies to promote collaborative decision-making, b) a specific sequence of topics for discussion, c) wording to convey key trial concepts and d) communication techniques to avoid subtle coercion and render conflicts of interest explicit. Applying this typology in evaluating informed consent consultations in clinical trials for cancer treatment, Brown, Butow, Ellis, et al. (2004) found considerable variation in practice. Many oncologists paid lip service to shared decision-making, by merely offering the option of delaying treatment decision. Key content was often omitted: the rationale for randomisation was covered in less than half of consultations. Moreover, as the authors acknowledge, while this methodology identifies whether the recruiter has raised an issue, it does not capture how participants interpret the information or whether the invitation to express views is taken up. A growing body of literature demonstrates an association between communication behaviour and patient outcomes in treatment decision-making (Arora, 2003; Ong, de Haes, Hoos, & Lammes, 1995). Shared decision-making (Charles, Gafni, & Whelan, 1999) is advocated in life-threatening diseases such as cancer (Gatellari, Butow, & Tattersall, 2001; Ong et al.,1995). Yet current approaches to informed consent conform more closely to the informed model of decision-making than the shared model (Charles et al., 1999). The emphasis is on what information must be provided in one direction, from health professional to patient, with the patient deliberating on treatment options and reaching a decision. Shared decision-making (two-way exchange of information between professional and patient, joint deliberation and joint decision-making, Charles et al., 1999) has been advocated for informed consent discussions (Brown, Butow, Butt, et al., 2004), but there is little evidence of it taking place in practice (Brown, Butow, Ellis, et al., 2004). This study aimed to open the ‘‘black box’’ of what goes on during informed consent appointments in a large ongoing multi-centre RCT, the ProtecT study (Prostate testing for cancer and Treatment,

2019

investigating effectiveness and cost effectiveness of three treatments for Prostate cancer, Donovan et al., 2003). The objectives were to investigate: 1] how study staff presented study information to participants; 2] evidence that emerged as to how well-informed participants were when proceeding to randomisation or treatment selection; 3] aspects of the communication process that may facilitate improvements in evidence of informed consent. It was intended that findings would be used to develop advice to improve informed consent appointments to RCTs more generally. Methods Main study design The ProtecT (Prostate testing for cancer and Treatment) study involved a programme of prostate specific antigen (PSA) testing amongst men in the community, inviting those with localised prostate cancer to be randomised to one of three treatments (Donovan et al., 2003). Multi-centre research ethics committee approval was obtained. Men aged 50–69 years in GP practices in nine UK centres were invited to an appointment and given detailed written and spoken information about the implications of having a PSA test, uncertainties about treatments and the need for a randomised trial of treatment. Those consenting to testing who had abnormal results were offered further diagnostic tests including biopsy. Those diagnosed with localised prostate cancer attended an appointment with a urologist to discuss the diagnosis and be given a detailed written PIS and introductory spoken information about the treatment trial comparing radical surgery (RS), radical conformal radiotherapy (RT) and active monitoring (AM, regular PSA tests and treatment as required). Participants attended a longer informed consent appointment (‘information appointment’) scheduled a week later, to allow an opportunity to absorb the information given. The information appointment was with a trained research nurse whose aim was to assist the man to reach an informed decision about whether to participate in the RCT and consent to randomisation, or choose treatment outside the RCT. Design of present study The study reported here is a qualitative study embedded within the main RCT. Qualitative research was integrated into both feasibility (Donovan et al., 2002) and main studies: information appointments were routinely tape-recorded to investigate differences in recruitment rates between centres and help train new staff (Donovan et al., 2008). This qualitative study used audio-recordings of information appointments to investigate interaction between recruiters and potential participants and was primarily conducted by JW (appointed to the ProtecT team in 2005 so not previously involved in ProtecT research). Participants Purposive sampling ensured the selection of a wide range of audio-recordings of appointments: from three study centres, over an extended time-period, including appointments conducted by several recruitment staff with different approaches to obtaining informed consent, and among participants with a range of sociodemographic characteristics. Variations in randomisation rates (the percentage of those eligible consenting to participate in the RCT) occurred between centres and over time (Donovan et al., 2008) and facilitated sampling of appointments for this study. Examples of each of three outcomes defined a priori to reflect potentially varying levels of informed consent were included:

2020

J. Wade et al. / Social Science & Medicine 68 (2009) 2018–2028

a) Participant consented to randomisation and accepted treatment allocation. Ideally this outcome reflects high levels of informed consent but may conceal poor understanding or passive acceptance of the trial. b) Participant consented to randomisation but rejected treatment allocation. This outcome, where the allocation was rejected immediately, was assumed to indicate a lack of equipoise reflecting difficulties with the informed consent process. Ideally participants should be in equipoise when randomised therefore unlikely to reject the allocation immediately. c) Participant refused randomisation and chose treatment. Ideally this outcome reflects high levels of informed decision-making but may conceal poor levels of understanding. Procedure Audio-recordings were fully transcribed with all personal data anonymised to ensure confidentiality. Thematic, content and conversation analyses were used in combination. Thematic analysis involved the inductive identification of codes from the data (Krippendorff, 2004; Silverman, 2001) using constant comparison techniques pioneered in grounded theory (Glaser & Strauss, 1967; Miles & Huberman, 1994). Analysis was undertaken in several ways: on each transcript separately, then with groups of transcripts analysed together by outcome, by centre and early or late in the time-period, until saturation was reached. As themes emerged, the researcher returned to the raw data looking for negative or deviant cases to test emergent themes and ensure these were well grounded in the data. Content analysis involved identification and definition of codes before searching for these in the data (Krippendorff, 2004; Neuendorf, 2002) and was applied specifically to identify evidence of participant views on treatments and evidence of equipoise at the point of deciding whether to be randomised. Conversation analysis (CA) rests on the principle that all utterances are social actions connected in sequences. As sequences of actions have patterns, what one participant says and does is shaped by what has previously been said and will in turn shape what will come (Maynard & Heritage, 2005; Silverman, 2000). Sections of the transcript for detailed scrutiny using CA were identified during thematic analysis and transcribed in more detail (see Appendix B). CA enabled exploration of overall structural organisation as well as the sequence, design and timing of conversational turns (Drew & Heritage, 1992) including overlapping talk and the organisation of turn-taking (Schegloff, 2000). Participant contributions were analysed in the context of the conversation with the recruiter with the aim of finding evidence about how information was received and interpreted, the success or failure of the information exchange, and to identify patterns most likely to facilitate and provide evidence of participant understanding (Heritage & Robinson, 2006). Data analysis proved to be a lengthy and highly complex process as the focus moved back and forth between thematic analysis, content analysis and CA as findings emerged, with the methods of each contributing to the findings separately and in combination. To check coding reliability, four other qualitative researchers independently evaluated twelve appointments. Codes were crosschecked with JW and areas of disagreement resolved with reference to the raw data. Researchers were blinded by the trial coordinator (JAL) as to which study centre was involved and where the appointment fell within the period studied. Sampling and analysis continued concurrently so that data saturation determined sample size. JW completed the analysis and produced detailed descriptive accounts, which were discussed in detail with JD to produce the findings.

Findings Appointments (n ¼ 23) were sampled from three study centres over a three-year period (November 2000–January 2004), involved 12 recruitment staff, and included a range of potential recruitment outcomes and participants across the age and social spectrum (Table 1). Most participants had the commonest clinical cancer stage, and were accompanied during appointments (Table 1). Thematic analysis of appointment content and CA of appointment structure revealed variations in the presentation and content of information provided by recruitment staff. Content analysis then identified evidence of participant views and equipoise when deciding whether to be randomised. Application of CA to analyse turn-design and turn-taking subsequently revealed patterns of communication that either facilitated or impeded evidence of participant views becoming available. Findings are detailed in turn below.

How study staff presented study information to participants Recruitment staff were given a checklist to ensure they covered essential study information: diagnosis, advantages and disadvantages of treatments, determining treatment outside the trial, the need for an RCT, the purpose of randomisation, the right to refuse participation or take time to consider, and inviting a decision as to how to proceed. As senior nurses, they delivered this information using their clinical experience, with considerable variation in their approach. CA of structural organisation revealed that the format of most appointments (n ¼ 20) fell into one of two categories: recruiter-led or participant-led. Three appointments combined elements of both (Table 2). Recruiter-led appointments Recruiter-led appointments were most common (n ¼ 12). In these, recruiters controlled and dominated the agenda (Appendix A, Box 1), providing information in checklist sequence. Participants were invited to comment or ask questions as each topic was concluded. These appointments followed proposed models of good practice by delivering requisite information in sequence and systematically attempting to elicit participant views (Brown, Butow, Butt, et al., 2004; ICH, 1996).

These participants expressed uncertainty as to whether they were in equipoise, but indicated they would consider all three treatments if allocated.

Participant-led appointments Eight appointments followed a ‘‘question and answer’’ format: the participant effectively controlled the agenda, putting questions to the recruiter in the order they chose, persisting until satisfied with the information provided (Appendix A, Box 2). Checklist content and sequence were not necessarily followed and some appointments deviated markedly from proposed models of good practice (Brown, Butow, Butt, et al., 2004) both in content and order of presentation. However, thematic analysis revealed more evidence of participants asking questions and expressing concerns about treatments or study processes (Appendix A, Box 2, lines 73– 75, 78–80, 89–91) than in recruiter-led appointments. Evidence of participant views and equipoise Findings of the CA of structural organisation, content analysis and eventual outcome as regards decisions to be randomised are summarised in Table 2. Content analysis revealed that in some appointments (P1, P3, P8), views of participants about treatments were largely absent prior to the decision about randomisation, despite invitations to voice views. CA of these appointments showed that unmarked responses (e.g. ‘‘mm’’, ‘‘yeah’’, ‘‘right’’ Appendix A, Box 1) predominated. Unmarked responses may function to encourage a speaker to continue their turn or may indicate implicit rejection of the relevance of information given (Heritage & Sefi, 1992). These appointments provided insufficient evidence to determine whether or not participants fully understood the implications of treatment options. In these appointments plus P14, there was insufficient evidence to judge whether the participant was in equipoise. All these appointments were recruiter-led. By contrast, all participant-led appointments provided evidence about participant views of treatments and their position regarding equipoise. Appointment structure was therefore associated with the extent to which participant views about treatments and their position regarding equipoise were voiced. Recruiter-led appointments provided supposedly essential information systematically, but did not necessarily

enable participant views to emerge. Participant-led appointments, by contrast, provided information in a tailored way: some ‘‘essential’’ topics were omitted, but participant views were always expressed. Participant-led appointments therefore consistently enabled the recruiter (and researcher) to reach judgements about participant levels of understanding and position regarding equipoise. Communication strategies to elicit patient views Participant views emerged in some recruiter-led appointments, indicating that structural factors alone did not account for all differences (Table 2). CA of turn-design and turn-taking identified communication strategies that were associated with successful elicitation of participant views about treatment and equipoise regardless of structure and these strategies are illustrated below. Question design, pauses and overlapping speech The use of open questions elicited views and beliefs rapidly, allowing recruiters (R) to identify which issues participants (P) wished to address (lines 1 & 8):

Open questions were highly effective, but not always sufficient to elicit concerns. At times recruiters needed to combine open questions with deliberate pauses. In recruiter-led appointments, recruiters presented large amounts of detailed information about a treatment, before inviting questions. Some participants needed time to formulate questions, particularly when recruiters spoke at length. The following extract follows the recruiter’s exposition of surgery lasting 3 min 49 s. During this time the participant contributed 55 turns to the conversation, the vast majority of them (50) consisting of minimal turns (e.g. ‘yeah’, ‘mm’, ‘right’), with only five major turns (e.g. ‘About the size of a walnut or something is it?’).

Another successful technique for eliciting views was for the recruiter to cede the floor rapidly where overlapping speech occurred. In Fragment 4, the recruiter was explaining randomisation, in response to participant questions. The participant attempted to take the floor (line 4): the recruiter ceded at once (line 3 ‘yeah’). This, combined with the use of continuers (lines 6, 8, 10, 13, 16, 18), enabled him to raise concerns about impotence.

3.

No not really [uh:::m

4.

[It’s usually (.) five to seven days in hospital Dxx if everything goes according to plan .hhh (P3, randomised to RP and accepts).

The invitation for questions (lines 1–2) was phrased as a closed question, inviting a yes or no response (contrast with ‘What are your thoughts on surgery?’). The participant’s response ‘no,’ (line 3) was qualified (‘not really’) and followed by ‘uh:::m’, functioning to hold his turn while he reflected. The recruiter, however, failed to react to these signals, beginning her next turn in overlap with him (line 4). She acknowledged the overlap by leaving a micro pause (line 4) for him to take the floor (Schegloff, 2000) but when he failed to do so, she continued her description of surgery, again dominating with minimal contributions from the participant. By contrast the recruiter in Fragment 3 left an exceptionally long pause (line 2, over 4 s) after asking why this participant rejected RT. This recruiter combined pauses with the use of continuers (e.g. ‘mm’, ‘right’ lines 4, 11, 14, 16), successfully encouraging this participant to explain his thinking.

Where recruiters failed to cede the floor, expression of concerns could be prevented or delayed (see Fragment 2 above). Fragment 5 shows multiple attempts by a participant to articulate concerns before eventual success. This exchange began with the participant‘s request to be randomised. He also voiced reservations about surgery (lines 5, 6 and 8) and denied fear was an issue and was attempting an explanation (line 8) when the recruiter increased the volume of her voice, signalling her desire to take the floor (Schegloff, 2000, line 9). She and the participant’s wife reassured him fear was normal (despite his denial of fear) and that he would receive optimum care (lines 9–29). He successfully signalled his wish to take the floor and explained his anxieties related to heavy lifting duties at work (lines 30–42). Three more times he attempted to articulate fear of incontinence (Fragment 6, lines 94, 134–136 and 171–172), succeeding on the final attempt. Twice his meaning was misinterpreted and inappropriate reassurance given (e.g. about the cancer being localised, lines 107–109) before he finally articulated his concerns (lines 171–172). Had this recruiter and his wife ceded the floor more readily, allowing him space to articulate his concerns, much time would have been saved and the risk of never addressing this man’s concerns would have been avoided.

Systematic eliciting and addressing concerns Eliciting participants’ beliefs and treatment preferences was not necessarily easy, even when recruiters used the above techniques. Some men found difficulty expressing concerns about sensitive issues, e.g. incontinence or impotence. In Fragment 7 the recruiter answered the participant‘s concern as he initially articulated it (lines 1–2) with general comments about the advantages of surgery (lines 5–9). The man’s emphatic repetition that he saw no advantage to surgery (line 15) indicated this had not addressed the issue. He then revealed his concern was incontinence (lines 18–19). Once explicit, the recruiter could address this. The process of communication in appointments where concerns were explored in depth was therefore cyclical: repeat questioning and probing enabled participants to articulate concerns. Recruiters then provided specifically tailored information and elicited further concerns until, ideally, all had been addressed. Some men expressed treatment preferences and a reluctance to be randomised as appointments began, and became more convinced of these as discussion continued. However, where recruiters elicited preferences or concerns systematically and addressed them specifically, several came to appreciate the uncertainty regarding which treatment was best and to accept randomisation. Others developed new preferences. Fragment 8 illustrates how a participant articulated this revision process aloud. This participant disliked the idea of regular blood tests (lines 6–7) and assumed these were only required under AM (lines 24, 27–31) but was informed

[ That’s right yeah yeah

175. Wife with things like that if you [ did 176. R

[ Yeah

177. Wife have a lot of bother with your bladder they could help you (P11 randomised to RP and accepts)

they were required for all treatments (lines 8, 10–12). His comment ‘Mmm that’s very interesting’ (line 36), a marked acknowledgement in CA, indicated acquisition of new information. His next comment revealed he now viewed AM as an option but reservations about radiotherapy persisted (lines 38–39), so discussion shifted to eliciting and addressing these concerns, providing further evidence of him revising his views (Fragment 9, lines 270–271). This man chose to be randomised and was assigned RT. After time to reflect, he rejected the allocation and chose AM which he had initially rejected. The exchanges in Fragments 8 and 9 suggest that information provided during the appointment influenced his final choice. Where recruiters failed to elicit and address concerns as systematically as this, there was little evidence to judge a man’s level of knowledge or understanding. When one participant expressed a strong aversion to surgery (Fragment 10, lines 3 and 11), the recruiter made no attempt to explore his reasons but continued her description of treatments (lines 12–13). This recruiter described the treatments, the rationale for the trial and purpose of randomisation in detail and only then, at the point of

making a decision regarding randomisation, elicited the participant’s preference for AM. Rather than explore the reasons, the recruiter simply accepted it (Fragment 11). Structural analysis showed this recruiter presented essential trial information and invited questions from the participant. Detailed analysis revealed a failure to elicit participant views other than in these two instances. This participant’s selection of AM may have been an informed decision, but there was little evidence available to substantiate this. Ascertaining the level of equipoise Randomisation only becomes a rational and ethical option for an individual when they are well informed and in a position of ‘equipoise’ (Chard & Lilford, 1998). As men absorbed information and revised their views during appointments, it was often difficult to judge whether they were sufficiently close to equipoise to consider randomisation, or whether they retained clear treatment preferences (e.g. Fragments 8 and 9). This could be made explicit by recruiters asking whether a participant would be prepared to accept each of the three treatments, or one that he had expressed concerns about (e.g. Fragment 9 line 344–346). This strategy helped expose remaining reservations for discussion (e.g. Fragment 8 lines 38–39). Recruiters also used this technique very effectively to emphasise that randomisation was not recommended if people were not in equipoise (Fragment 12). This strategy was notably lacking from appointments where participants were randomised then immediately rejected the allocation (P1, P19). Its use might have exposed their lack of equipoise and led to further discussion and clarification before proceeding either to randomisation or treatment choice.

as to how well-informed participants were when proceeding to randomisation or selecting treatment, and identify aspects of the communication process that facilitated this evidence becoming available. Previous research has suggested that highly structured consent processes are more effective in ensuring essential information is conveyed (Brown, Butow, Ellis, et al., 2004; Dunn & Jeste, 2001). Other research, however, has indicated that people make sense of information in complex and unexpected ways (DixonWoods et al., 2007; Featherstone & Donovan, 2002). This study found that recruiter-led appointments were more likely than participant-led appointments to conform to research guidelines by providing required information systematically (ICH, 1996), but evidence as to how participants understood this information was lacking from several recruiter-led appointments. Even when recruiters employed strategies conventionally identified as promoting shared decision-making (e.g. inviting questions, Brown, Butow, Butt, et al., 2004), participant contributions were limited. In these cases, there was insufficient evidence for the recruiter or researcher to judge the participant’s level of understanding or position regarding equipoise. By contrast, participant-led

appointments might not cover all ‘essential’ information or follow a routine structure. However, they consistently provided evidence that participants were able to articulate concerns, giving the recruiter and researcher insight into participant levels of understanding and enabling a judgement as to whether they were in equipoise. Further analysis using CA revealed variations in recruiters’ communication strategies that enabled or impeded participants in expressing their views. Recruiters who systematically used open questions and pauses and readily ceded the floor were more successful in enabling participants to articulate concerns than those who failed to utilise these techniques, regardless of whether appointments were recruiter-led or participant-led. The degree to

which recruiters were systematic in applying these strategies determined both the extent to which concerns were voiced and the presence of evidence in the interaction that concerns had been addressed. In particular, the degree to which recruiters successfully explored and exposed participant beliefs about treatments was crucial in providing evidence about whether participants were in equipoise. These findings suggest the focus on what content must be provided in informed consent appointments should broaden: how recruiters approach this task is equally important. The most effective appointments for providing evidence that participants were well-informed were those where recruiters applied the strategies identified above to explore participants’ concerns systematically and establish clearly whether participants were in equipoise. Least effective appointments were those in which recruiters reproduced information provided in the PIS and invited questions. Concepts of equipoise and randomisation, implications of treatments, right to choose treatment or withdraw remain the bedrock of informed consent discussions and should be included in the PIS (Brown, Butow, Butt, et al., 2004; ICH, 1996). However, these appointments present a unique opportunity for the twoway exchange of information. If exploration of an issue demonstrates it is well understood or irrelevant to an individual’s decision-making, time may be better spent on more relevant issues. Recruiters should use the informed consent appointment to explore individual views about trial or treatment processes systematically, and establish participant positions regarding equipoise. This can be done within a recruiter-led or participantled framework; the very nature of the strategies employed may favour participant-led approaches. There will always be a tension in obtaining informed consent between the objective of maximising recruitment and ethical concerns to ensure that participation or non-participation is fully informed (Boulton & Parker, 2007). These findings highlight the pivotal relationship between whether a recruiter has clarified the presence or absence of equipoise and the decision made regarding randomisation. Randomisation is only ethical where evidence of equipoise emerges (World Medical Association, 2004). If a recruiter

fails to elicit views or concerns effectively, there will be insufficient evidence of equipoise. Application of strategies identified here may help protect participants against coercion: the systematic use of open questions and pauses to encourage participants to voice views, concerns and preferences makes leading questions less likely. Audio-recording of appointments enables practice to be monitored and training of recruiters targeted (De Salis, Tomlin, Toerien, & Donovan, 2008; Donovan et al., 2008). When the strategies identified are applied systematically, numbers opting to be randomised and accepting the allocation can reach high levels (Donovan et al., 2008). Some participants in this RCT used discussions with the recruiter to confirm treatment preferences. For others, systematic eliciting and addressing of concerns regarding treatments or trial processes resulted in a perspective shift from treatment preference to consent to randomisation and acceptance of allocation. Variation in participant preferences for information is well documented (Degner & Sloan, 1992; Gatellari et al., 2001). The proposed approach would enable discussion to be tailored to the needs of the individual in a truly patient-centred way (GMC, 2008) incorporating principles of shared decision-making (Charles et al., 1999). Findings have implications for the training of professionals who recruit to RCTs. Strategies that proved most effective in eliciting participant views were relatively simple (open questions, long pauses, readily ceding the floor) and some have been identified elsewhere as highly effective in eliciting information from patients in doctor–patient consultations (Heritage & Robinson, 2006; Schwabe, Howell, & Reuber, 2007). Some, such as long pauses, do not occur naturally in communication, but training should ensure that recruiters are comfortable applying such techniques. A major strength of this study was the innovative application of CA in addition to thematic and content analyses, allowing assessment of the contributions of all parties, interacting in real time (Maynard & Heritage, 2005). This enabled a more patient-centred analysis of the information exchange (Ong et al., 1995), with participants equal parties in communication. Previous investigations have focussed only on conduct of recruiters (Albrecht et al., 1999; Brown, Butow, Ellis, et al., 2004; Jenkins et al., 1999; Tomamichel et al., 1995). By examining more and less successful exchanges, it was possible to identify patterns that were facilitating or inhibiting information exchange. Evaluation of future interventions applying these techniques to improve informed consent appointments would benefit from application of CA as a method of analysis. The study has some limitations. Use of audio- rather than videorecordings resulted in the exclusion of some non-verbal information. Data were limited to audio-recordings of appointments, without triangulation with observations or interviews to verify findings with the parties. Additional data might have shed light on motives for particular patterns of communication, and levels of insight about the impact of communication practices, but use of appointments meant that the focus of the research was on the presentation of information and reaction of RCT participants in a ‘real-life’ situation, without later interpretation. Data available for analysis reflected what would be available during appointments to recruiters seeking to satisfy themselves that participants were well informed and in equipoise before proceeding to randomisation. The study was limited to investigating recruitment in one RCT, but the plausibility of the findings suggests applicability more generally, particularly in view of the very different options offered in the ProtecT study, ranging from no active intervention to invasive surgery. Although this study focussed on how study staff presented information to participants, evidence emerged that participant strategies could override recruiter strategies. Further research is

needed to investigate the impact of participant communication on information exchange.

Conclusion Ensuring high levels of informed consent in RCTs requires considerable commitment by recruiters. The current focus on what information should be provided to participants must be broadened to include consideration of how information is best conveyed and how it is interpreted. A model of tailored information provision using the positive communication strategies identified to elicit and address participants’ concerns and clearly establish their position regarding equipoise is proposed. When these techniques were systematically employed, more evidence emerged of participants’ understanding of key issues, with the result that evidence was available to judge whether consent for randomisation was truly informed.
