Defining Speaking Up in the Healthcare System: a Systematic Review.

BACKGROUND: Communication issues have been shown to contribute to healthcare errors. For years healthcare professionals have been told to "speak up." What "speak up" means is unclear, as it has been defined and operationalized in many ways. Thus, this study aimed to systematically review the literature regarding definitions and measurements of speaking up in the healthcare system and to develop a single, comprehensive definition and operationalization of the concept. METHODS: PubMed, CINAHL, PsychoInfo, and Communication/Mass Media Complete databases were searched from 1999 to 2020. Publications were included if they mentioned speaking up for patient safety or any identified synonyms. Articles that used the term speaking up concerning non-health-related topics were excluded. This systematic review utilized Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: A total of 294 articles met the inclusion criteria, yet only 58 articles focused on speaking up. While the most common synonym terms identified were "speak up" and "raise concern," only 43 articles defined speaking up. Accordingly, a modified definition was developed for speaking up-A healthcare professional identifying a concern that might impact patient safety and using his or her voice to raise the concern to someone with the power to address it. DISCUSSION: Speaking up is considered important for patient safety. Yet, there has been a lack of agreement on the definition and operationalization of speaking up. This review demonstrates that speaking up should be reconceptualized to provide a single definition for speaking up in healthcare.

Relative foveal dark adaptation: a potential method for assessing macular health.

BACKGROUND/OBJECTIVE: Dark adaptation measures photoreceptor recovery following intense light stimulation. Time to recovery reflects retinal function. We describe a novel method of relative foveal dark adaptation using an iPhone. Data from a small number of healthy subjects were studied to assess reproducibility, effects of age, and consider potential clinical utility. METHODS: Relative foveal dark adaption was studied in 6 normal subjects across ages from 20 to 81 years and across differing testing conditions. Foveal bleaching is produced by fixating a bright white circle on an iPhone for variable times. After foveal bleaching an annular surround appears to complete a bullseye stimulus with surround initially brighter than centre. As the fovea recovers the centre regains brightness. Relative foveal dark adaptation, the time for the visual anchor to shift from surround to centre, was studied across a range of bleaching times, ages, and testing conditions. RESULTS: Dispersion of dark adaptation times grows with increasing age. Foveal bleaching for 30 s was as effective as longer times. Testing times with a 30 s bleach were less than 1 min. Foveal dark adaptation was reproducible within each subject and was unaffected by ambient room lighting, pupil size, and light attenuation. Repeat, immediately sequential testing was similarly reproducible except after long bleaching. CONCLUSIONS: This method of dark adaptation is intuitive, repeatable, and relatively unaffected by testing condition. Testing times are brief, requiring only an iPhone screen positioned at reading distance. Relative foveal dark adaptation may be a useful tool to assess macular health.

Automated vision screening of children using a mobile graphic device.

BACKGROUND/OBJECTIVE: Can measuring interocular brightness disparity, acuity, and colour vision classify children with amblyopia? SUBJECTS/METHODS: Two hundred eight subjects (3-14 years) were recruited for a prospective, observational protocol to measure interocular brightness disparity, uniocular acuities with and without a pinhole, and colour vision using an iPad. Subjects looked through polarizing filters and chose the brighter of two spaceships to measure interocular brightness disparity. The differential brightness of image pairs was varied through a staircase algorithm until equal brightness was perceived. Acuities and colour vision were tested with tumbling Es and AO-HRR colour plates, respectively. Unilateral amblyopia was later confirmed in two subjects. RESULTS: Binocular brightness balance on the iPad detected amblyopes with 100% sensitivity and specificity. Using 20/30 as cutoff for normal acuity, 1 of the amblyopes was detected, and non-amblyopes were excluded by visual acuity pinhole testing. The mean difference between iPad and E-Chart visual acuities with pinhole was 0.02 logMAR with limits of agreement from -0.08 to +0.11 logMAR. iPad and printed plates Colour vision testing produced identical results. Testing times were brief and exit pleasure responses were positive. Mean and range testing times for Brightness Sense, Colour vision, and Visual Acuity were 32.7 s (range = 12-63 s), 52.8 min (range = 17-95 s), and 88.75 s (range = 41-188 s), respectively. CONCLUSIONS: Interocular brightness disparity, acuity, and colour vision can be measured in children as young as 3 years old solely through playing a game on a mobile device. Interocular brightness disparity is a sensitive and specific method to detect unilateral amblyopia.

Disaster education for nursing students: A successful partnership with the American Red Cross.

BACKGROUND: Educating nursing students on disasters is an essential component of baccalaureate nursing curriculum. Implementing effective education during and for rare events, such as disasters or pandemics, can be difficult for nursing programs attempting to cover required content. METHOD: This curriculum improvement project was integrated into our community clinical course over several semesters. Through a no cost partnership with the American Red Cross, we were able to educate students in disaster nursing and complete required clinical hours. A combination of online education with in-person or virtual simulation was facilitated by the American Red Cross and hosted by our university. RESULTS: Students met learning objectives through completion of online learning and a simulation experience. Student perceptions of the learning experience were positive. Through this partnership110 students completed training as new Disaster Health Service volunteers for the American Red Cross. CONCLUSION: This community partnership will remain part of our curriculum and could be replicated in other nursing programs. This model has demonstrated effectiveness in both the in-person and virtual class setting, allowing flexibility in content delivery.
