Exploring a transformative solution is driven by the inefficiencies inherent in the traditional manual, paper-based outpatient record management system at Don Mariano Marcos Memorial State University (DMMMSU). This research introduces the Medical Out-Patient Records Management System (MORMS) to fill this gap. Developed through the software development lifecycle, this OMRMS optimally maintains outpatient records; therefore, it assists medical professionals in recording, organizing, and retrieving patient data effortlessly. Notably, statistical reports represent data trends that are an invaluable product. The overall approval of MORMS was unanimous during User Acceptance Testing (UAT), with each tested component receiving a 100 percent acceptability index. Based on this assessment, it can be concluded that there is a high likelihood of integrating the system into the daily processes of DMMMSU’s medical officers across all its three campuses because its usefulness is valued by them. Moreover, usability testing validates the functional practicality of MORMS with respect to the Computer System Usability Questionnaire subscales -system usefulness, information quality, and interface quality. Consistent median ratings of 1 for these scales indicate pragmaticity or practicability; dependability; precision and ease of use, which are some merits of this methodical tool. Consequently, not only gaining acceptance from users but also being highly usable makes MORMS effective in complying with various requirements set by different groups within DMMMSU’s medical staff.
