Integrative Review of Non-Technical Skills Frameworks to Apply for Air Medical Transfer of Pregnant Women.

OBJECTIVE: To identify the most suitable non-technical skills framework to adapt and apply to the air medical transfer of pregnant women. DATA SOURCES: Embase, PsycINFO, PubMed, MEDLINE, Web of Science, CINAHL, Science Direct, and Google Scholar. STUDY SELECTION: We retrieved potentially relevant articles using a predefined combination of keywords extended with truncation and Boolean operators. Database and manual reference searches yielded 569 peer-reviewed articles. We included articles if they presented empirical data and described non-technical or cognitive competency skills frameworks for health care professionals. We discussed any ambiguities regarding inclusion, and they were resolved by consensus. We retained 71 full-text articles for final review. DATA EXTRACTION: We coded extracted data under four criteria: non-technical skill categories, context of use, psychometric properties, and rating system. We generated descriptive summary tables of the characteristics of existing non-technical skills frameworks based on publication year, method of development, clinical setting, clinical specialty, routine/crisis-based performance, and team/individual performance. DATA SYNTHESIS: We identified 42 non-technical skills frameworks from a variety of health care settings. We critically examined context of use and how use in various clinical settings may align with air transfers of pregnant women. Our findings illustrate the importance of team-based and routine performance rather than crisis-focused skills. Maintaining situational awareness throughout all stages of the transfer and communicating effectively with team members, the pregnant woman, and her partner are skills that are particularly important to ensure good outcomes. CONCLUSION: We selected the Global Assessment of Obstetric Team Performance as the most suitable non-technical skills framework to adapt to the clinical setting of air medical transfer of pregnant women. We considered the clinical specialty, specific non-technical skills required in the setting, the framework's properties, and the requirement to focus on routine team performance.

Non-technical skills evaluation in the critical care air ambulance environment: introduction of an adapted rating instrument--an observational study.

BACKGROUND: In the isolated and dynamic health-care setting of critical care air ambulance transport, the quality of clinical care is strongly influenced by non-technical skills such as anticipating, recognising and understanding, decision making, and teamwork. However there are no published reports identifying or applying a non-technical skills framework specific to an intensive care air ambulance setting. The objective of this study was to adapt and evaluate a non-technical skills rating framework for the air ambulance clinical environment. METHODS: In the first phase of the project the anaesthetists' non-technical skills (ANTS) framework was adapted to the air ambulance setting, using data collected directly from clinician groups, published literature, and field observation. In the second phase experienced and inexperienced inter-hospital transport clinicians completed a simulated critical care air transport scenario, and their non-technical skills performance was independently rated by two blinded assessors. Observed and self-rated general clinical performance ratings were also collected. Rank-based statistical tests were used to examine differences in the performance of experienced and inexperienced clinicians, and relationships between different assessment approaches and assessors. RESULTS: The framework developed during phase one was referred to as an aeromedical non-technical skills framework, or AeroNOTS. During phase two 16 physicians from speciality training programmes in intensive care, emergency medicine and anaesthesia took part in the clinical simulation study. Clinicians with inter-hospital transport experience performed more highly than those without experience, according to both AeroNOTS non-technical skills ratings (p = 0.001) and general performance ratings (p = 0.003). Self-ratings did not distinguish experienced from inexperienced transport clinicians (p = 0.32) and were not strongly associated with either observed general performance (r(s) = 0.4, p = 0.11) or observed non-technical skills performance (r(s) = 0.4, p = 0.1). DISCUSSION: This study describes a framework which characterises the non-technical skills required by critical care air ambulance clinicians, and distinguishes higher and lower levels of performance. CONCLUSION: The AeroNOTS framework could be used to facilitate education and training in non-technical skills for air ambulance clinicians, and further evaluation of this rating system is merited.

Fatigue in Air Medical Clinicians Undertaking High-acuity Patient Transports.

Abstract Background. Fatigue is likely to be a significant issue for air medical transport clinicians due to the challenging nature of their work, but there is little published evidence for this. Objective. To prospectively assess the levels and patterns of fatigue in air medical transport teams and determine whether specific mission factors influenced clinician fatigue. Methods. Physicians and flight nurses from two intensive care interhospital transport teams routinely completed fatigue report forms before and after patient transport missions over a 4-month period. Data collected included subjective ratings of fatigue (Samn-Perelli and visual analog scale), mission difficulty and performance. Multivariate hierarchical logistic and linear models were used to evaluate the influence of various mission characteristics on post-mission fatigue. Results. Clinicians returned 403 fully complete fatigue report forms at an estimated overall return rate of 73%. Fatigue increased significantly over the course of missions, and on 1 of every 12 fatigue reports returned clinicians reported severe post-mission fatigue (that is, levels of 6 or 7 on the Samn-Perelli scale). Factors that impacted significantly on clinician fatigue were the pre-mission fatigue level of the clinician, night work, mission duration, and mission difficulty. Poorer self-rated performance was significantly associated with higher levels of fatigue (r = -0.4, 95% CI -0.5 to -0.3), and for the 6-month period leading up to the study clinicians reported a total of 22 occasions on which they should have declined a mission due to fatigue. Conclusions. These results suggest that clinicians undertaking interhospital transports of even moderate duration experience high levels of fatigue on a relatively frequent basis. In the unique and challenging environment of air medical transport, prior fatigue, long or difficult missions, and the disadvantageous effect of night work on normal circadian rhythms are a combination where there are minimal safety margins for clinicians' performance capacity. Fatigue prevention or fatigue resistance measures could positively affect air medical clinicians in this context.

Air transport by the Wellington Flight Service: a descriptive analysis of interhospital transfers over a 5-year period in the Wellington region of New Zealand.

AIM: To describe and characterise the interhospital transport workload of a New Zealand based flight service over a 5-year period. METHOD: Wellington Flight Service database records from 1 November 2005 to 31 October 2010 were reviewed. Details of mission purpose, timings, transport type, severity of illness, clinical service requesting the transfer, and medical crew in attendance, were examined. RESULTS: The Flight Service completed 4046 transport missions over 5 years. The median mission duration was 4.5 hours, but 9% of missions took 8 hours or more. Fixed wing aircraft were used for most transports (70%) with the trend for helicopter use decreasing steadily (from 23% down to 13%). High proportions of transfers were requested by cardiac services (25%), neurosurgery (14%) and ICU (9%), and 72% of those transported were critically (Category A) or seriously ill (Category B). A doctor accompanied a specialist flight nurse for Category A transports but for only 14% of Category B transports. 26% of missions began after 4pm and a further 6% began after midnight. Missions undertaken during the night were usually transfers of the critically or seriously ill (90%), with most (70%) being retrieved to Wellington Hospital for tertiary care. CONCLUSION: The Wellington Flight Service undertakes 2.2 interhospital transfers per day. Further examination of clinical outcomes in this cohort of patients transported to tertiary care is required to fully evaluate these services.

Symptom-based categorization of in-flight passenger medical incidents.

INTRODUCTION: The majority of in-flight passenger medical events are managed by cabin crew. Our study aimed to evaluate the reliability of cabin crew reports of in-flight medical events and to develop a symptom-based categorization system. METHODS: All cabin crew in-flight passenger medical incident reports for an airline over a 9-yr period were examined retrospectively. Validation of incident descriptions were undertaken on a sample of 162 cabin crew reports where medically trained persons' reports were available for comparison using a three Round Delphi technique and testing concordance using Cohen's Kappa. A hierarchical symptom-based categorization system was designed and validated. RESULTS: The rate was 159 incidents per 106 passengers carried, or 70.4/113.3 incidents per 106 revenue passenger kilometres/miles, respectively. Concordance between cabin crew and medical reports was 96%, with a high validity rating (mean 4.6 on a 1-5 scale) and high Cohen's Kappa (0.94). The most common in-flight medical events were transient loss of consciousness (41%), nausea/vomiting/diarrhea (19.5%), and breathing difficulty (16%). DISCUSSION: Cabin crew records provide reliable data regarding in-flight passenger medical incidents, complementary to diagnosis-based systems, and allow the use of currently underutilized data. The categorization system provides a means for tracking passenger medical incidents internationally and an evidence base for cabin crew first aid training.

Duration of condition is unrelated to health-state valuation on the EuroQoL.

OBJECTIVE: To determine whether health valuations, such as those used in economic evaluation, are affected by duration of a health condition. People with disabling health conditions tend to value health more highly than members of the general population, and one explanation for this is that over time their experience of living with a disabling illness changes the way in which they value health. If this is so, a relationship between the duration of an individual's disabling health condition and the valuation they assign to their health-state might reasonably be expected. DESIGN: A postal survey using the EuroQoL (EQ-5D) instrument to collect descriptions and valuations for health from people who reported a diagnosis of either stroke or multiple sclerosis. Contact with participants was made through national support organizations and questionnaires were returned by mail. RESULTS: Eight hundred and ninety-four people completed the survey. One hundred (11 %) had one health-state indicating moderate problems in all five dimensions of the EQ-5D descriptive profile. For people with this health-state, analysis of covariance showed no relationship between valuation of health-state and time from onset of illness (F = 0.38, p = 0.54). This finding applied irrespective of the diagnosis, and for some other less frequently reported health-states. CONCLUSION: Clinical experience suggests that over time people adapt to long-term disability. However we found no evidence to support the proposition that higher health-state valuations by people with disabling conditions are explained by the actual duration of their condition.
