The thesis argues that synthesising a domain-specific classification scheme/taxonomy with Branford’s standardised AcciMap approach will improve the reliability and validity of its outcomes. Based on Waterson et al. (2017)’s review of the AcciMap methodology, this argument discussed the need for improving the AcciMap approach rather than simply developing novel accident analysis approaches. One recommended way to achieve this includes combining the AcciMap approach with existing error-based classification schemes as part of the “remixing process”. Recent studies implementing this process include the UPLOADS classification scheme based on the AcciMap methodology for investigating led outdoor activities (Australia). This example supports the need to develop a health-specific AcciMap approach, as Goode et al. (2017) argued for accident analysis, including health IT analysis.

The Medi-Socio AcciMap taxonomy approach built on Branford’s standardised AcciMap method was proposed. This novel approach was applied to analysing a significant health-IT related incident (Septra overdose of a patient) as detailed in the Digital Doctor book (Wacther, 2015). Standardised AcciMap and Medi-Socio AcciMap taxonomy approaches were applied to this incident to identify contributing factors, causal relationships (links) and formulate safety recommendations. In assessing the reliability of both AcciMap versions, professionals (Clinical safety/human factors practitioners, NHS) participated in the Septra overdose incident analysis. The validity assessment involved safety experts experienced in using the AcciMap method and applied the two AcciMap approaches to the incident.

Qualitative and quantitative measurements were used to analyse and compare findings between professional users (reliability) and expert results (validity) based on causal/contributing factors, causal relationships and safety recommendations. These studies indicated lower reliability and validity scores for the Medi-Socio AcciMap taxonomy than the standardised AcciMap version, particularly relating to contributing factors and safety recommendations. Outcomes on reliability and validity studies, including usability, were discussed. Also, study limitations, research reflections, and recommendations were presented for future research.
