Anaesthetists' attitudes to teamwork and safety

A questionnaire survey was conducted with 222 anaesthetists from 11 Scottish hospitals to measure their attitudes towards human and organisational factors that can have an impact on effective team performance and consequently on patient safety. A customised version of the Operating Room Management Attitude Questionnaire (ORMAQ) was used. This measures attitudes to leadership, communication, teamwork, stress and fatigue, work values, human error and organisational climate. The respondents generally demonstrated positive attitudes towards the interpersonal aspects of their work, such as team behaviours and they recognised the importance of communication skills, such as assertiveness. However, the results suggest that some anaesthetists do not fully appreciate the debilitating effects of stress and fatigue on performance. Their responses were comparable with (and slightly more favourable than) those reported in previous ORMAQ surveys of anaesthetists and surgeons in other countries.     

Anaesthetists' attitudes to monitoring instrument design options

A survey into the attitudes of anaesthetists to features inmonitoring instruments, particularly the design of alarms, visualwarnings, alarm limits and the general instrument interfaceis reported. Questions in the survey had short introductionsoutlining a clinical scenario followed by items that proposedalternative design features that an instrument might have. Participantswere asked to grade their responses to these alternatives ona scale of 1 (strongly disagree) to 5 (strongly agree). The resultssuggest that anaesthetists would welcome the use of more advanced technologyin instrument design. They prefer context-specific messages andalarms. They reject overt control systems for delivering anaesthesia, exceptfor use in exceptional circumstances. Generally, the preferencesof anaesthetists are consistent with known principles of safe,ergonomic design. Br J Anaesth 2000; 85: 781–4 Footnotes ^* Corresponding author     

Anaesthetists' attitudes towards awareness and depth-of-anaesthesia monitoring

Advances in technology have resulted in the development of several depth-of-anaesthesia monitors. Whether any of these monitors can reduce the incidence of awareness is an important issue for anaesthetists and their patients. We therefore surveyed a random selection of anaesthetists, asking for their opinions of awareness and depth-of-anaesthesia monitoring in current clinical practice. Approximately half (52%) of the anaesthetists surveyed had experienced a patient with awareness. Anaesthetists considered that they had a lower incidence of awareness in their own practice when compared with others, 1:5000 vs. 1:10 000 (p < 0.001). Anaesthetists rated awareness on an 11-point scale as only a moderate problem, median (interquartile range) 5 (2-7). Older anaesthetists were less likely to rate the importance of awareness highly (p = 0.009) and to use awareness monitoring (p = 0.001). Anaesthetists are prepared to use depth-of-anaesthesia monitoring more widely if it can be shown to prevent most cases of awareness in routine practice.     

Anaesthetists' intentions to violate safety guidelines

The Theory of Planned Behaviour has been used to investigate the likelihood that anaesthetists will routinely perform three violations of safety guidelines. The three violations were: failing to visit patients before surgery, failure to perform pre-anaesthetic equipment checks and the silencing of alarms during anaesthesia. These suggested violations arose from discussions with the Medical Defence Union. In forming the intention not to perform these violations, anaesthetists are most influenced by their normative beliefs about the violation, i.e. the opinion they believe a group of peers and other significant other people would hold about them performing the violation. The next most influential factor is their personal norms, i.e. beliefs that the individual has about whether the violation is really right or wrong, followed by behavioural beliefs, i.e. beliefs about the consequences of performing the violation, and control beliefs, i.e. beliefs about how much control they have over performing the violation. The results show that the more intense the anaesthetists' belief that the violations were important, the less likely they were to violate, except for the case of alarm silencing. This result suggests that there may be a basic lack of confidence in the reliability of audible alarms that undermines their utility.
