Usability analysis of contending electronic health record systems

In this paper, we report measured usability of two leading EHR systems during procurement. A total of 18 users participated in paired-usability testing of three scenarios: ordering and managing medications by an outpatient physician, medicine administration by an inpatient nurse and scheduling of appointments by nursing staff. Data for audio, screen capture, satisfaction rating, task success and errors made was collected during testing. We found a clear difference between the systems for percentage of successfully completed tasks, two different satisfaction measures and perceived learnability when looking at the results over all scenarios. We conclude that usability should be evaluated during procurement and the difference in usability between systems could be revealed even with fewer measures than were used in our study. © 2019 American Psychological Association Inc.

Describing the use of social media as a point-of-care tool in facility-based emergency care in Africa

Background Despite privacy and legal concerns, social media is used to provide real-time clinical support to emergency care providers. It can be particularly beneficial for those in Africa, who might lack adequate training or access to information. This PhD aimed to describe the use of social media as a point-of-care telemedicine tool in facility-based emergency care in Africa, to further inform its use. Methods A scoping review was conducted to map available literature on use, benefits, and risks associated with social media as a point-of-care platform. A mixed methods approach was then taken using a cross-sectional survey and semi-structured interviews to obtain a comprehensive description of use of social media as a point-of-care tool in facility-based emergency care in Africa. Results The scoping review identified 13 publications describing use of social media as a point-of-care tool in emergency medical settings. No studies were located in low-income countries. All studies evaluated WhatsApp use for real-time consultations, and those that assessed reliability found it to be highly reliable for consultations. A total of 70 emergency care providers in African facilities responded to the survey; nearly all worked in low- or lower-middle-income countries. Responses showed that clinicians use social media multiple times each day, primarily to share and receive advice. The majority felt social media positively impacts patient and provider experiences and improves speed and safety. Finally, eight African emergency care providers were interviewed to gain an in-depth understanding of how social media use impacts emergency care. All participants noted routine use for a range of professional purposes, including consultations, administrative tasks, and education. Concerns were mentioned by all participants, including legality, privacy, and lack of employer regulations. Conclusions This dissertation provides insight into social media use of African emergency care physicians, showing that social media use in this group is ubiquitous. Most clinicians use social media multiple times each day for a range of point-of-care purposes, and many feel social media is positively impacting both the patient and provider experiences. Post-doctoral work will focus on developing a framework to guide use of social media in facility-based emergency care in the African setting
