Improving patient safety, within the context of a complex system, forms one of the key challenges in health care today. Cognitive work analysis (CWA) is one way to analyze complex systems, and although it has been applied to health care for 20 years, little is known about its effectiveness or future research needs. This article presents a review of CWA studies in health care, addressing questions of use, usefulness, challenges, and opportunities. Results of the review make clear that the research agenda is largely confined to acute care. Of the 39 articles reviewed, 28 relate to this setting. There appears to be a growing interest in medical informatics, error investigation, and decision support. Conversely, work in physiological monitoring has slowed, associated with the uncertainties of modeling "biological" systems. Studies related to "organic" social systems are similarly challenged, although there is a recognition that important opportunities exist, such as studying work flow processes between teams. Other opportunities relate to new methods to enhance CWA; new technologies, such as auditory displays; and new applications, such as requests for proposals and incident investigation. Ultimately, the capacity to foster an understanding into the deep structures of a system may prove to be the greatest contribution of CWA to health care today.

Background Individuals with spinal cord injury (SCI) are at high risk of experiencing secondary conditions like pressure injuries. Self-management programs may reduce the risk of complications, but traditional programs have proven to be insufficiently tailored to the needs of people with SCI. To overcome barriers to self-management support, a web-based, self-management program was developed for Canadians with SCI called SCI & U. Objective This study aims to evaluate the feasibility and potential impact of the SCI & U program in the context of a mixed methods pilot study. Methods The study followed an explanatory, sequential mixed methods design. Participants (N=11) were Canadians with SCI who had been living in the community for more than 1 year. Each took part in a self-paced, six-session self-management program guided by a trained peer health coach. During sessions, participants could discuss a health topic with their coach from a predefined list (eg, skin or bowel management). Quantitative data were gathered before and after program participation to assess program feasibility and impact. Feasibility measures included attrition rates, frequency of topics selected, and recorded goals, whereas impact measures included measures of self-efficacy (University of Washington Self-Efficacy Scale [UW-SES]), mood (Personal Health Questionnaire Depression Scale [PHQ-8]), secondary conditions (Spinal Cord Injury Secondary Conditions Scale [SCI-SCS]), and resilience (Spinal Cord Injury Quality of Life Resilience Scale [SCI-QOL-R]). Qualitative measures were based on postintervention interviews; these were designed to confirm and expand on quantitative Results Of the 11 participants, 10 completed pre- and postassessments, and 6 coaching sessions. Sessions lasted between 31 and 81 min (average 55, SD 13), and the duration of the program ranged from 35 to 88 days (average 56, SD 23). Diet and exercise were selected as topics 40% (20/50 sessions with topics) of the time, whereas topics such as mental health, bladder management, pain, and bowel management were chosen less frequently. Results gathered before and after the pilot study demonstrated improvements with moderate effect sizes on the UW-SES and the electronic health literacy scale (ie, Hedges g>0.5). Effect sizes for measures of resilience (SCI-QOL-R), depression (PHQ-8), and secondary conditions (SCI-SCS) were small (ie, Hedges g>0.3). Qualitative results confirmed a common focus on diet and exercise, and defined coaches as sources of accountability, information, reassurance and affirmation, and emotional and technical support. Conclusions Results demonstrated that a web-based self-management program is feasible and acceptable by Canadians with SCI. Results also indicated a web-based, peer-led self-management program may impact resilience, self-efficacy, mood, and secondary complications. Finally, results illuminated the role of the coach in facilitating behavior change. Future work seeks to validate results in the context of a randomized controlled trial.
