Does the AsistIAM mobile application improve usability and self-reported ACS management skills among primary care physicians?
The AsistIAM mobile application demonstrated high usability and improved self-reported ACS management skills among primary care physicians in rural and referral settings.
ABSTRACT Background Early management of acute coronary syndrome (ACS) is critical. Clinical guidelines are more consistently implemented in high‐complexity hospitals; however, in rural and primary care settings multiple barriers limit timely diagnosis and treatment. This study aimed to develop and evaluate the usability of a mobile application designed to assist primary care physicians in the diagnostic approach and initial management of ACS. Methods A mHealth tool named AsistIAM was developed with five modules: electrocardiogram pattern, reperfusion strategies, risk assessment, real‐time georeferencing, and educational content. Usability was assessed on a 1–7 scale under in both simulated and real‐world conditions. In the latter, a before‐and‐after study was performed with physicians from four rural primary healthcare centers and one referral hospital. In the pre‐implementation phase, participants completed a survey identifying barriers to ACS care. After using the app, they complete the same survey to analyze changes. Results A total of 18 participants evaluated the app in simulated conditions and 59 in real‐world settings. Mean usability scores were high (6.52, in simulation and 6.18 in real‐world). The best‐rated items were ease of learning, interface satisfaction, and availability of functions. After app implementation, physicians reported improvements in ECG acquisition and interpretation (81.4%–100%), recognition of ST‐elevation patterns (25.6%–39.2%), identification of referral centers (88.1%–98.0%), and correct use of fibrinolytics (errors 44.1%–17.6%). Conclusions AsistIAM represents an innovative tool to strengthen regional networks, improve ACS management and support timely clinical decision‐making. Usability results highlight its intuitive interface, functionality, and practical utility.
Díaz et al. (Wed,) conducted a observational in Acute coronary syndrome (ACS) (n=77). AsistIAM mobile application vs. Pre-implementation (baseline) was evaluated on Usability assessed on a 1-7 scale. The AsistIAM mobile application demonstrated high real-world usability (mean score 6.18/7) and improved physician-reported ECG interpretation (81.4% to 100%) and correct use of fibrinolytics.
