The term 'therapeutic misconception' (TM) was introduced in 1982 to conceptualize how some psychiatry trial participants perceived and interpreted their involvement in research. TM has since been identified in many settings and is a major component in research ethics discussions. A qualitative study included a subgroup of interviews with five parents (two couples, one mother) who declined to enrol their baby in a neonatal trial. Analysis suggested the possibility of a counterpart to TM which, given the original terminology, we term the 'injurious misconception' (IM). While TM is closely linked to the elision of care and research, and involves an over-stated sense of benefit and protection, IM may be a product of a particularly keen and discomforting sense of distinctions between care and research and a correspondingly over-stated sense of risk and threat.

Background: Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods: Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results: The case study demonstrates that trials need various categories of people to buy in -- hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion: The performance of future clinical trials could be enhanced if trialists routinely considered these factors. [ABSTRACT FROM AUTHOR]

Background: A commonly reported problem with the conduct of multicentre randomised controlled trials (RCTs) is that recruitment is often slower or more difficult than expected, with many trials failing to reach their planned sample size within the timescale and funding originally envisaged. The aim of this study was to explore factors that may have been associated with good and poor recruitment in a cohort of multicentre trials funded by two public bodies: the UK Medical Research Council (MRC) and the Health Technology Assessment (HTA) Programme. Methods: The cohort of trials was identified from the administrative databases held by the two funding bodies. 114 trials that recruited participants between 1994 and 2002 met the inclusion criteria. The full scientific applications and subsequent trial reports submitted by the trial teams to the funders provided the principal data sources. Associations between trial characteristics and recruitment success were tested using the Chi-squared test, or Fisher's exact test where appropriate. Results: Less than a third (31%) of the trials achieved their original recruitment target and half (53%) were awarded an extension. The proportion achieving targets did not appear to improve over time. The overall start to recruitment was delayed in 47 (41%) trials and early recruitment problems were identified in 77 (63%) trials. The inter-relationship between trial features and recruitment success was complex. A variety of strategies were employed to try to increase recruitment, but their success could not be assessed. Conclusion: Recruitment problems are complex and challenging. Many of the trials in the cohort experienced recruitment difficulties. Trials often required extended recruitment periods (sometimes supported by additional funds). While this is of continuing concern, success in addressing the trial question may be more important than recruitment alone. [ABSTRACT FROM AUTHOR]

Background: It is considered to be a fundamental ethical premise of human experimentation, that it should be carried out only where the effects of an intervention are unclear. The point at which it is considered that there is insufficient scientific and medical evidence to clearly state the superiority of an intervention has been termed equipoise. This concept has been the subject of much recent impassioned debate but little empirical research about the views of people involved in recruitment to randomized controlled trials (RCTs), and none in the particularly emotive area of neonatal intensive care. Methods: Thirty neonatologists recruiting into one or both of two neonatal RCTs in five centres in England were interviewed using a semi-structured schedule to explore their involvement in randomised trials. The interviews were tape-recorded and transcribed. Equipoise was one among a range of topics covered. Concepts relating to equipoise were identified by close reading of the entire interviews. Themes emerging from the data were noted in their contexts then discussed between the co-authors. Interviewees also completed a brief questionnaire about their demographic background, and their experience of research and RCTs. Results: Almost all the neonatologists used the concept of equipoise [using words and phrases such as uncertainty, lack of knowledge (or ignorance), strengths of views, and balancing of pros and cons] in their interview and, for most of them, equipoise seemed to be a useful term. They explored ideas about equipoise at the individual and community levels, and some linked equipoise with notions of the responsibility that should be exercised by the scientific and professional communities. They differed in the importance they gave to individual equipoise, and in how they reacted to threats to equipoise. Feelings of doubt about a trial and disturbed equipoise were more often expressed by more junior doctors. Conclusions: Our findings suggest that the concept of equipoise goes beyond the idea of uncertainty. In part this is because it includes the balancing of benefit and harm; this balancing is part of a professional obligation and requires engagement with 'expert' knowledge. Equipoise could therefore be seen as 'active' or 'responsible' uncertainty. Elucidation of this difficult concept may help to facilitate recruitment for both clinicians and parents in future trials and thereby help to find answers to important clinical questions.
