Objectives To understand whether aviation-derived human factors training is acceptable and useful to healthcare professionals. To understand whether and how healthcare professionals have been able to implement human factors approaches to patient safety in their own area of clinical practice.
Methods Qualitative, longitudinal study using semi-structured interviews and focus groups, of a multiprofessional group of UK NHS staff (from the emergency department and operating theatres) who have received aviation-derived human factors training.
Results The human factors training was evaluated positively, and thought to be both acceptable and relevant to practice. However, the staff found it harder to implement what they had learned in their own clinical areas, and this was principally attributed to features of the informal organisational cultures.
Conclusions In order to successfully apply human factors approaches in hospital, careful consideration needs to be given to the local context and informal culture of clinical practice.

What is already known about this subject
The human factors approach to patient safety, derived from aviation, has been widely used in healthcare, including the emergency department. It has been shown to be effective.
However, there has been no study that evaluates its acceptability to clinicians, or its sustainability in clinical practice.
What this study adds
Aviation based human factors training is both acceptable, and perceived as useful, for emergency department and operating theatre clinicians.
In the long term, it may prove hard to sustain in a UK NHS context.
It is becoming more widely acknowledged that there is ‘value’ associated with developing a greater awareness of human factors (HF) among healthcare staff in terms of improving patient safety in their clinical practice. In depth, qualitative studies of the implementation of interventions based on this approach remain rare. A recent comprehensive literature review of patient safety research in the UK1 suggests that ‘[human factors] ideas and concepts might benefit from adaptation and translation before being applied’ (p. 28) and that there is a ‘need for multi and mixed methods approaches to researching patient safety’. This study will therefore examine in detail the application of an HF approach in two departments in a large acute hospital. An HF approach considers the interplay between the healthcare staff providing care (people and culture) and the organisational and clinical contexts in which this care is delivered (systems and processes). It helps describe and explain the limitations and potential fallibility of human performance within complex socio-technical systems and links to broader contexts of organisational performance and risk management. The HF approach views causation of critical incidents and unplanned events in clinical practice as being a complex interplay between systemic and environment factors in the workplace and various well described (and normal) limitations in human performance, rather than being ‘errors’ made by blameworthy individuals.
The aviation HF approach has been enthusiastically embraced within healthcare, especially in the UK NHS,2 ,3 though this is not without its critics.4 While there is strong evidence that this is an effective approach in improving patient safety,5 there is less evidence about implementation and acceptability to professional staff in healthcare.6 ,7 Both Greenhalgh et al8 and Dixon-Woods et al9 show that the implementation of organisational innovations in healthcare is a complex process and prone to failure. Opposition from professional groups has proven to be a major obstacle to some of these innovations10 and it is thus important to establish how the aviation HF approach is viewed by professional staff in hospital, in this case, staff who took part in an HF training programme.
Current policy context
This study is particularly timely in the UK NHS policy context. The initial report11 on poor quality of care at the Mid-Staffordshire Hospitals NHS Trust showed that (among other criticisms) poor communication and teamworking, inadequate clinical and managerial leadership, and an organisationally widespread lack of focus on patient care caused a catastrophic collapse in patient safety and the quality of care. The second report,12 focused on the wider organisational context, has made similar criticisms. The reports of the Clinical Human Factors Group13 and the Department of Health Human Factors Reference Group14 both show the importance of the HF approach in addressing these issues.
HF has been successfully applied in the aviation industry, but whether it can be translated to healthcare, particularly the UK NHS context, has been questioned in the literature.4 This paper reports on an initiative which sought to apply the HF approach to clinical practice in the main operating theatres and emergency department (ED) in one UK NHS Trust. This Trust is in the Midlands of England and serves a population of 3 million. In 2012–2013 there were 110 000 admissions, 125 000 operations and 181 000 ED attendances. A group of senior professionals (consultant physicians and surgeons, experienced qualified nurses and theatre practitioners; n=20, 13 male, 7 female) were trained over 6 days by experts in HF from aviation to act as interprofessional faculty for HF training. Recruitment was by invitation, though there were no selection criteria other than seniority and experience. None of the ‘faculty’ group has any formal training in HF prior to this initiative.
Members of the faculty group then delivered a 6-day HF training programme to professional staff from ED and theatres (box 1).

Participants in this, the first course to be delivered (n=19, 6 male, 13 female), were included in this study. This initiative was clinically-led, and while the management of the hospital were aware of the HF programme, and supportive, they were not centrally involved in it.
The project was deemed by the relevant NHS research and development department to constitute service evaluation, and ethical approval was not necessary. Nonetheless, the research team ensured that written information about the study was provided to all participants, that written consent was taken, and that anonymity and confidentiality were maintained throughout.
Both faculty and course participants were drawn from the ED and operating theatres, and consisted of a range of clinicians including both senior and junior medical and nursing staff. Two focus groups (both of six participants, mixed in both profession and area of practice) were conducted with the first group of faculty during the initial training course, using the same topic guide (see online supplementary appendix A). They lasted an hour and were facilitated (alone) by one of the research team (ST, who has 20 years’ experience as a qualitative researcher, including extensive facilitation of focus groups) and recorded.
Ten semi-structured interviews were conducted with the faculty, and 11 with participants in the first course (for interview schedule, see online supplementary appendix B). Some faculty were therefore in a focus group and had a one-to-one interview. Interviews with faculty and course participants were conducted approximately 3 months after the programme had finished. This was a deliberate choice by the research team in order to establish how far the faculty and participants had been able to utilise the HF approach in their everyday practice and the interview schedule reflected this. All faculty and participants were invited to interview, and the sample reflects those who agreed to participate. Interviews were conducted by SB and BR, both of whom are experienced qualitative interviewers. No participant had prior contact with the research team, though they were provided with written information about the study in advance. The interviews and focus groups were transcribed, transcription checked against recordings, and then analysed thematically. This involved a process of coding for meaning and content, and then building themes by linking groups of codes together. This was done by one researcher (ST) and the initial analysis checked and agreed at a meeting of the whole research team. There was no validation of interviews or themes by faculty or course participants, though the themes discussed by faculty and participants were similar (table 1).
The main themes that emerged were evaluation, ‘trying to do it’, the social context, barriers to implementation and whether HF was a professional or managerial activity.
The programme was generally positively evaluated:
The best course I’ve ever done. (surgeon, faculty)
Bold and ambitious. (ED doctor, participant)
It gave the participants new ways of thinking about things and new ways of talking about them, such as situation awareness. Though there was uncertainty about ‘what HF was’ prior to joining the programme, after initial discussions common issues became clear. Prior to starting the programme, both faculty and participants were looking for new perspectives on long-term problems. Everyone found that the programme gave them the new insights that they hoped for. For some this was a major achievement: ‘a miracle’ and ‘amazing’. Bringing the tacit knowledge to the surface was a recurrent theme, with thoughts of ‘why the hell haven't we been doing it like that?’ (operating theatre nurse, participant). However, it has to be acknowledged that this, by virtue of the way the participants were recruited, is a self-selected sample of HF enthusiasts.
Tried to do it
All of the participants reported that they tried to put what they had learned into action, though it appears from the data that more senior participants had a wider scope to do this. Among the activities they reported were:
Thinking more about specificity in language.
Leadership and support for colleagues.
Being approachable to junior staff members.
Asking for feedback from colleagues.
Embed HF into other areas of work, such as mentorship and teaching.
Re-focus on the importance of teamwork.
Clarifying their role and responsibilities to themselves as well as others.
What these activities have in common is that they are largely focused on the individual's own work, rather than being attempts to influence their wider department or unit. This is linked to some of the contextual factors discussed below.
The social context
The social context proved to be a significant factor in interviewees’ accounts. There were notable differences between the ED and theatres. In the ED participants reported a sense of dilution and loss of momentum since the programme:
Nothing we thought we wanted to do has been introduced or developed in any way, shape or form. (ED doctor, participant)
This was attributed to problems of people working in isolation and participants returning to established cultures and communities of practice. In theatres there was perceived to be more of a natural fit with the way that things work anyway. Natural teams formed around individual theatres and the methodical, process nature of anaesthesia and surgery.
Differences related to the status and role of participants were also apparent. Senior staff appeared to integrate HF better into their roles, and they did not see a clear distinction between professional and leadership or management responsibilities. More junior staff saw management as something that was done by others.
Barriers to implementation
Despite the participants’ enthusiasm for the HF approach, and their attempts to implement it in their work, they perceived that there were substantial barriers to using it effectively. These were situated in organisational structures and cultures, and included a general unwillingness to change ways of working, especially if they were thought to involve additional work.
There was the handovers idea, which has stalled, I think is the best way of putting it, because there are so many other competing demands on my time. I think the problem with innovation in the NHS generally is there's no support for it. No-one really gives a monkey's (sic). (ED nurse, participant)
It was difficult to fund and protect time for training other staff in HF. The participants’ accounts when focused on their own areas of practice were largely positive. Talking about the meso and macro levels tended to elicit negative discussion around organisational problems, issues with ‘management’ and resourcing this work properly to enable it to be effective and continue. The concepts of HF were accepted but making changes was seen as a different matter. Concern was expressed that it was still limited to a few people in a couple of areas and therefore within the organisation it was relatively hidden and risked losing momentum. While broader managerial issues were raised as significant barriers, it is these deep-seated more cultural phenomena that were thought by participants to be more significant.
Is HF work a professional or managerial activity?
Participants found it difficult to separate the two:
I think everybody needs to have some understanding at least of human factors because it has an impact on any level of the NHS. (senior nurse, ED, participant)
Well, it's not managerial … I think it should be part of our day to day; it should be the foundation for everything we do at the sharp end. (theatre practitioner, faculty)
HF was seen as integral to roles at all levels, and was considered by participants to be part of professional self-regulation. However, a rather vaguely-defined ‘management’ were seen as having the organisational influence and resources to enable HF. The ‘management’ were perceived as having:
absolutely no concept about human performance at all. (senior nurse, ED, participant)
Acceptability and barriers to implementation
An HF initiative, derived explicitly from an aviation approach to HF, was found to be both acceptable and useful by a wide, albeit not totally representative, group of clinical staff. This is an encouraging finding, given the lack of qualitative evaluations of this approach in healthcare, and concern that it may not be appropriate. A key factor in its success appears to have been that the initiative was clinically-led, delivered largely by clinicians, and that management in the hospital appears to have taken a supportive, but ‘hands-off’ stance.
However, this needs to be balanced against the reported difficulties that participants had in putting HF into practice in a complex environment, which is usually held to be resistant to change.15 For all that this initiative fulfilled many of the criteria for success delineated by Greenhalgh et al,8 it appears to have encountered similar difficulties in implementation to other service improvement initiatives. The issues related either to organisational structure, that the hospital is a large, complex, bureaucratic organisation, or to the (informal) organisational culture16 which is not necessarily conducive to this kind of change. The data do contain some suggestions from participants about how these perceived organisational barriers might be overcome. First, they thought that it would be helpful if there had been a more structured and extensive follow-up to the HF programme, enabling them to continue to meet as a group for mutual support, and to discuss ideas about how some of the barriers might be overcome, possibly on a community of practice model.17 This has been implemented by the HF training course since this study was done. Second, for all that the disengaged but supportive stance of the hospitals’ management was helpful in ensuring the acceptability of the HF initiative, participants realised that they needed much more active support from managers, both local and corporate, in order to bring about the kinds of changes that they sought in their own workplaces. They thought that managers needed to facilitate the development of an HF approach by allowing the release of staff to attend training, funding that training, and, where necessary, funding some of the initiatives that had arisen from the HF work. Third, participants were of the view that the HF approach would work much better if all staff had received HF training, including, in this context, the highest levels of senior management to the most ‘junior’ staff and students.
Professional or managerial activity
The question of whether HF work is a professional activity or a managerial one is interesting, and it has a substantial bearing on the success and sustainability of HF initiatives like the one studied in this paper. Though the issue of doctors (in particular) acting as managers has been discussed in the literature, and some of the tensions about how this relates to ideas about being ‘professional’ have been delineated, this has not been considered in the context of HF. In addition, the clinically-led nature of the HF initiative studied here may have led to it being perceived differently by professionals, rather than, as many service improvement initiatives are, being imposed by the hospital's management.
A range of findings on this issue are presented in the literature from doctors who have embraced managerial roles, such as the GPs studied by Pickard,18 who shows how the medical profession has been, as she terms it, reprofessionalised, ‘incorporating a new series of managerially defined competencies and a new type of clinical autonomy’ (p. 255). In the GPs studied, these changes were viewed quite positively. Likewise, Jones and Green19 and Kirkpatrick et al20 also show how doctors have increasingly become involved in management. The doctors and nurses studied by McDonald et al21 found their managerial role more ambivalent, and Iedema et al22 found tensions between acting as clinician and manager. While these more ambiguous or nuanced positions appear common in the literature, there is also evidence of outright resistance.22
The clinicians we studied exhibited some of the ambiguity found by McDonald et al.21 While they were generally enthusiastic about leading HF work, they became more ambivalent if it led them into more formally ‘managerial’ activity, and this seemed problematic for some of them. Despite the new forms of more organisational professionalism analysed by, for instance, Evetts,23 there was still a residual resistance by clinicians to work that could be perceived (by themselves or others) as ‘managerial’. This phenomenon would also explain some of the quite strongly held views that many issues that were relevant to HF were the responsibility of the ‘management’, and not clinicians. So, for all that this HF initiative was clinical in origin, clinically-led, and facilitated by clinicians, if it led practitioners in a direction that appeared more directly managerial, then this was a problem. This quite deep-seated concern about managerial work may prove to be an obstacle to the development of HF in healthcare.
What is perhaps surprising in our findings, given the emphasis that the HF approach gives to issues like ‘the authority gradient’, was that they remained problematic for the clinicians involved. For all that the senior staff who had been through the programme sought to be, for instance, more approachable, they were aware that their seniority remained an obstacle to certain issues being raised with them. Likewise, more junior staff felt that, despite change being perceptible, they did not feel able to challenge senior staff on some issues. The fact that only a minority of staff in both ED and operating theatres had undertaken the HF training tended to exacerbate this problem. We would thus caution against the HF approach being seen as a ‘quick fix’ for organisational culture. In healthcare, organisational cultures can be long-standing, and thus obdurate, and it appears that they can be an issue in HF implementation as much as in any other service improvement initiative, for all that HF attempts to address these issues head-on. These findings also confirm the importance of HF being a component of undergraduate curricula.24
These include the fact that this study was done at a single Trust, and that only one investigator conducted the focus groups. The selection process for the HF training may have biased the comments.
The aviation approach to HF proved to be usable and acceptable to participants. Despite its perceived strengths, it appears to have come up against many of the obstacles that other organisational change initiatives in the NHS, and healthcare more broadly, have encountered. In the light of the strong policy push (outlined above) for the widespread adoption of the HF approach in healthcare in the UK, this paper contains important practical lessons for healthcare providers, educational institutions and individual professionals. HF is a meaningful and useful toolkit for professionals interested in service improvement. However, the organisational context needs to be right for HF to be fully effective, and this should not be underestimated.
