Requirements specification for automated fall and injury risk assessment

Fall and injury prevention continues to be a challenge in the acute care environment. Identification of patients at risk can guide preventive care for these individuals. The following study employed usability engineering methods via a series of focus groups, to specify functional and design requirements for an automated Fall-Injury Risk Assessment Instrument. Focus groups were held with interdisciplinary decision makers and end-users to identify functional and design specifications for the automated instrument. The results were mapped to usability heuristics, which were used to guide design decisions. The main elements identified were data completeness, workflow processes, resource access, and cognitive burden. The main usability factors identified were efficiency of user, match with real world, error prevention, recognition not recall and minimalist design. Focus groups are a useful methodology to specify requirements for healthcare applications. Outcomes evaluation of the automated instrument is in process.
