BackgroundMany studies identify factors that contribute to renal prescribing errors, but few examine how healthcare professionals (HCPs) detect and recover from an error or potential patient safety concern. Knowledge of this information could inform advanced error detection systems and decision support tools that help prevent prescribing errors.ObjectiveTo examine the cognitive strategies that HCPs used to recognise and manage medication-related problems for patients with renal insufficiency.DesignHCPs submitted documentation about medication-related incidents. We then conducted cognitive task analysis interviews. Qualitative data were analysed inductively.SettingInpatient and outpatient facilities at a major US Veterans Affairs Medical Centre.ParticipantsPhysicians, nurses and pharmacists who took action to prevent or resolve a renal-drug problem in patients with renal insufficiency.OutcomesEmergent themes from interviews, as related to recognition of renal-drug problems and decision-making processes.ResultsWe interviewed 20 HCPs. Results yielded a descriptive model of the decision-making process, comprised of three main stages: detect, gather information and act. These stages often followed a cyclical path due largely to the gradual decline of patients’ renal function. Most HCPs relied on being vigilant to detect patients’ renal-drug problems rather than relying on systems to detect unanticipated cues. At each stage, HCPs relied on different cognitive cues depending on medication type: for renally eliminated medications, HCPs focused on gathering renal dosing guidelines, while for nephrotoxic medications, HCPs investigated the need for particular medication therapy, and if warranted, safer alternatives.ConclusionsOur model is useful for trainees so they can gain familiarity with managing renal-drug problems. Based on findings, improvements are warranted for three aspects of healthcare systems: (1) supporting the cyclical nature of renal-drug problem management via longitudinal tracking mechanisms, (2) providing tools to alleviate HCPs’ heavy reliance on vigilance and (3) supporting HCPs’ different decision-making needs for renally eliminated versus nephrotoxic medications.

The battlespace is a volatile and complex environment in which tactical commanders face cognitively challenging responsibilities, compounded with the increased complexity of emerging cyber warfare. It is critical that tactical commanders gain adequate situation awareness for effective decision making to achieve mission success. While current tools enable distribution of large quantities and types of information, they do not adequately support the underlying cognitive work and information needs of tactical commanders. We performed a domain analysis using Cognitive Task Analysis methods, developing a prototypical operational scenario representative of current and envisioned environments, centered on a cyber-attack. Using this analysis, we identified cognitive and information requirements for information displays that support effective tactical decision making. Tactical commanders need to understand dynamic situations in the field, understand the viable courses of actions, know how their mission fits into the larger mission, and communicate with their company subordinates and higher echelons of command.

Rotorcraft pilots face a number of unique challenges in shipboard-landing maneuvers. Even very experienced rotorcraft pilots find such maneuvers to be challenging and delicate, as they require the pilot's undivided attention. To minimize risk, these maneuvers are conducted within well-defined boundaries associated with weather and visibility. To expand the envelope of safety, technological aids that augment decision-making capabilities and reduce pilot workload are being proposed. Our paper reports a cognitive task analysis, which involved interviews with five rotorcraft pilots experienced in shipboard-landing maneuvers. Our results reveal cognitive elements in which expertise plays a critical role. We have articulated our understanding on why pilots are faced with difficulties during these critical points, which led us toward design recommendations and system requirements for technological aids and their displays. We have also identified a number of system limitations and quantities of interest, which may be useful in safety evaluations.

Within the sport of rugby league, there exists a perceived shortage of talent in playmaking positions. In Australia, an academy dedicated to the development of playmaking skills has recently been established. Although the precise skills targeted by the academy for development are yet to be determined, decision making is presumed to be integral. The current research used the naturalistic decision-making paradigm to inform training initiatives by investigating the decision processes engaged by rugby league playmakers. The research explored whether players of varying ability could be differentiated in relation to a key decision process, cue use. Rugby league playmakers were interviewed using a novel variation of cognitive task analysis, which used both retrospective (i.e., recalled game) and prospective (i.e., unfamiliar rugby league scenario) means. The sample comprised 10 participants: six professional and four semiprofessional rugby league players. From a content analysis, a concept map, cognitive demands tables, and a critical cue inventory were produced. Results indicated that professional players demonstrated greater cue discrimination, assigned different meaning to the cues, and processed cues in a different manner compared with their semiprofessional counterparts. The results offer insights for future training applications in the domain and raise important questions regarding the utility of critical cue inventories in training.
