Patients’ Usability Experience With a Postoperative Follow-Up Web Application

Surgical complications increase morbidity, mortality, and costs, underscoring the need for effective postoperative follow-up. Digital tools can reduce complications, but their usability remains unexplored in Ecuador. This study evaluated the usability of a postoperative monitoring app among 62 patients from a public hospital using the System Usability Scale (SUS). The mean SUS score was 65.69 (SD = 18.68), indicating moderate usability. Participants rated ease of use (M = 3.31) and confidence (M = 3.40) favorably but reported challenges with complexity (M = 1.85) and need for support (M = 1.56). Younger and more educated users scored higher, though differences were not statistically significant; no gender-based variations emerged. Positive perceptions were associated with ease of use and system integration, while perceived complexity and need for support negatively impacted the user experience. These findings suggest that optimizing the interface and strengthening user education may equip younger adults with digital tools that facilitate long-term engagement and adoption across future generations.
