BACKGROUND AND OBJECTIVES

Technological advancements are reshaping healthcare, particularly through mobile health (mHealth) applications that aid chronic disease management. Medication tracking apps, such as Simpill, have shown potential in improving outcomes for conditions like hypertension. However, disparities in digital literacy and concerns related to technology acceptance and privacy may hinder effective use. Grounded in the principles of the Design Thinking approach, this study sought to evaluate the relationship between health-seeking behavior (HSB), perceived barriers (PB), and the perceived usability (PU) of Simpill among middle-aged hypertensive adults. The research aimed to capture not only measurable associations but also to inform future app development through a user-centered lens that prioritizes empathy and real-world usability.

METHODS

A quantitative, descriptive-correlational research design was employed to assess respondents’ HSB, PB, and PU related to Simpill. The study was guided by core phases of the Design Thinking framework, particularly empathize and define, to ensure a deep understanding of user needs and usability constraints. Data were collected using a four-part, researcher-modified questionnaire administered to 138 purposively selected middle-aged adults (30–59 years old) residing in Barangay Industrial Valley, Zone 6, Marikina City, Philippines. All participants had a confirmed diagnosis of hypertension. Correlational analyses, including Kendall’s Tau B, were conducted to examine relationships among the variables. The integration of Design Thinking informed the development and interpretation of questionnaire items, aligning them with real-world challenges experienced by the target users.

RESULTS

The study investigated the relationship between HSB, PB, and the PU of Simpill among 138 middle-aged hypertensive individuals. Most respondents were female (55.8%), aged 50–59 (47.8%), and employed in non health-related sectors (95.7%). HSB levels were gene rally high (mean = 3.23), particularly in actively seeking health information, while lower engagement was noted in routine vital sign monitoring. PB were moderate (mean = 2.06), with unfamiliarity with the application cited as a common issue. PU was also rated as moderate (mean = 2.80), although ease of use received a low score (mean = 1.99). A weak positive correlation was found between HSB and PU (Kendall’s Tau B = 0.123, p = 0.049), while a moderate negative correlation existed between PB and PU (Tau B = -0.402, p < 0.001). These findings reflect insights derived from the Design Thinking "empathize" phase, suggesting that while proactive health behaviors may modestly support app engagement, unresolved user pain points—such as poor usability and lack of familiarity—remain significant obstacles to adoption. The results underscore the importance of moving to the "ideate" and "prototype" phases, where such user insights can directly shape the redesign and improvement of mHealth tools.

CONCLUSION

The study identified a high level of health- seeking behavior, reflecting the respondents’ engagement with their health and openness to guidance, consistent with the user-empathy foundation of Design Thinking. Moderate perceived barriers highlight existing challenges in technology adaptation, particularly among those who prefer traditional methods. The moderate PU rating of Simpill, especially in terms of ease of use, suggests the app’s current design does not fully align with user capabilities or expectations. In line with Design Thinking principles, particularly user-centered innovation, the findings emphasize the need to involve users in iterative co-design processes to improve mHealth solutions. Addressing perceived barriers through enhanced digital literacy, usability testing, and interface refinement could substantially boost app acceptance and effectiveness in real-world settings.

Introduction: The Hearing for Life (HeLe) is a novel newborn hearing screening device initially designed according to specifications of clinicians of the Philippine National Ear Institute (PNEI). Unfortunately, targeted end-users, rural health workers, had difficulty using it. This research applied the user-centered design (UCD) methodology involving rural health workers in recommending design, content, and function requirements for HeLe. Objectives: This study aims to 1) describe how UCD was applied in a time-limited and resource-constrained environment, 2) assess the usability of the design prototypes, and 3) recommend design, content, and function requirements for HeLe. Methods: This research is a descriptive study using mixed methods. Six rural health units (RHU) involved in the HeLe research program were purposively selected for the study. There were 30 participants included, five health care workers per RHU. Applying the UCD method, the study had three phases: 1) user profiling (where participants accomplished a survey questionnaire, 2) inspiration phase (focus group discussions, workflow analysis, and interviews with a technical expert were conducted), and 3) ideation phase (designing and assessment of prototypes were done). Results: Participatory methods and structured procedures (i.e., card sorting, MoSCoW matrix prototyping, etc.) were applied to help determine and prioritize user requirements and elicit user feedback. These methods were chosen considering the time and resource constraints in the RHU. The prototype's System Usability Scale (SUS) score (81.94) was higher than the SUS score previously obtained (68) from the older version of the interface. Accuracy, durability, in-app instructions, feedback, and an easily understood interface were the most requested requirements for the telemedicine device. The need for the technology to be aligned with the RHU's workflow and available resources was highlighted in the focus group discussions. Conclusions The study documents practices and lessons learned in applying UCD methodology in design and development that have been demonstrated to improve usability of the device. The involvement of the users surfaced in the design, content, and functional requirements which can guide future iterations of HeLe and contribute to better understanding of ways to develop user-friendly telemedicine devices in the Philippines. This paper emphasizes that users should be involved in the entire process and not just recipients of the technology.

This study evaluates a Massive Open Online Course (MOOC) on Emergency Medicine designed by iEM Education Project and Lecturio, using a validated checklist to assess its usability and user experience. The MOOC received a high score for cognitive connection (>4/5), in four components including interactivity, content and resources, media use, and instructional assessment. However, for learner guidance and support, the score was 2.75/5, indicating that the course did not provide clear instructions on how learners can get support or feedback from teachers when encountering problems in the course. For affective and functional connections, all components received a high overall mean score of more than 4/5. The course was impactful to the users who were in their early clinical years, as they were actively engaged and were motivated to complete the course. However, improvements should be made to better stimulate learning by improving learner feedback and providing space for collaborative learning online. Evaluation of MOOC applying the heuristics of usability and user experience identifies specific components of online learning course apart from rating the severity of acceptance or violation of instructional design principles. The information derived from usability and user experience studies can improve design and delivery of online courses.
