Clinicians' perspectives on wearable sensor technology as an alternative bedside monitoring tool in two West African countries.

OBJECTIVE: Healthcare facilities in low- and middle-income countries (LMICs), especially in Africa, suffer from a lack of continuous bedside monitoring capability, adversely affecting timely detection of hemodynamic deterioration and the opportunity for life-saving intervention. Wearable device technologies can overcome many of the challenges of conventional bedside monitors and could be viable alternatives. We assessed clinicians' perspectives on the use of a novel experimental wearable device ("biosensor") to improve bedside monitoring of pediatric patients in two West African LMICs. METHODS: Focus groups were conducted in 3 hospitals (2 in Ghana and 1 in Liberia), in both urban and rural settings and of variable size, to elucidate clinicians' attitudes about the biosensor and to identify potential implementation needs. The focus group sessions were coded using a constant comparative method. Deductive thematic analysis was applied to pair themes with Consolidated Framework for Implementation Research (CFIR) contextual factors and domains. RESULTS: Four focus groups were conducted in October 2019, and included 9 physicians, 20 nurses, and 20 community health workers. Fifty-two codes in four thematic areas were linked to 3 CFIR contextual factors and 9 domains. Key themes were durability and cost of the biosensor, hospital setting, and staffing concerns, which were related to the "Inner Setting" and "Characteristics of the Intervention" CFIR contextual factors. Participants, who recognized the limitations of current vital sign monitoring systems, further identified 21 clinical settings in which a biosensor could potentially be useful and expressed willingness to implement the biosensor. CONCLUSION: Clinicians who provide care to pediatric patients in two West African LMICs suggested multiple uses of a novel experimental wearable biosensor and expressed willingness to use it for continuous bedside vital sign monitoring. They identified device design (e.g., durability, cost), hospital setting (rural vs urban), and staffing as important factors to consider during further development and implementation.

TRUE-Bolivia: Trauma Responders Unifying to Empower Communities in Santa Cruz, Bolivia.

BACKGROUND: The aim of this study is to assess the efficacy of the TRUE-Bolivia (Trauma Responders Unifying to Empower Communities Bolivia) trauma first responder course at improving participant confidence in first responder abilities and increasing knowledge of trauma response skills. METHODS: Participants attended the 4-h TRUE-Bolivia course at the municipal department of urban transportation and universities and medical schools in Santa Cruz, Bolivia and completed a demographic survey and pre- and post-course knowledge assessments. All participants who attended the full course and completed both knowledge assessments were included in the study, with 453 people attending at least one portion of the course and 329 completing the full course and assessments. RESULTS: A majority of participants were men, had completed high school or attended university, and worked or trained in the fields of transportation or medicine. Participant ratings of confidence on a 5-point Likert scale improved from a median of 3 (interquartile range [IQR] 2) before the course to 5 (IQR 1) after the course (P < 0.01). The median number of correct answers on the pre-course nine-question knowledge assessment was 3 (IQR 3), improving to 7 (IQR 3) on the post-course assessment (P < 0.01). All demographic groups demonstrated improvements in scores from the pre- to post-test. Female gender, higher education level, a background in medicine, and prior training in first aid were associated with higher pre- and post-test scores. CONCLUSIONS: The TRUE-Bolivia course increased knowledge of first responder skills and improved confidence in these abilities in participants from a variety of backgrounds. Further study is needed to determine the long-term skill utilization by participants and the course's impact on local trauma morbidity and mortality.
