<![CDATA[Background: Sentra Medika Cikarang Hospital migrated from Avicenna to Teramedic in December 2024. Initial evaluations revealed infrastructure constraints, user literacy, and interface complexity that impacted system effectiveness. Objective: To measure the effectiveness of the implementation of Teramedic SIMRS through quantitative and qualitative analysis, and to formulate optimization recommendations. Subjects and Method: Convergent mixed methods design: cross-sectional survey (n = 111 respondents) for variables of wait time, data accuracy, interface, organizational support, satisfaction; and in-depth interviews with 15 key informants from IT, inpatient, medical records, pharmacy, and HR units. Quantitative data were analyzed using descriptive statistics, paired t-tests, and multiple linear regression. Qualitative data were analyzed thematically. Results: The survey showed an average reduction in clinical data wait time from 110 (SD= 15) to 86 (SD= 12) minutes (p < 0.001), an increase in medical record accuracy from 92% to 97% (p < 0.01), and an average user satisfaction score of 4.1/5. Regression analysis confirmed that digital literacy ( β = 0.45, p <0.001) and organizational support (β= 0.37, p < 0.001) significantly influenced satisfaction. Qualitative findings identified four main themes: infrastructure challenges (power outages, network), user adaptation and training, UX/UI design, and module integration. Conclusion: Teramedic SIMRS improves efficiency and data quality, but infrastructure and interface barriers need to be addressed through UPS upgrades, redundant networks, ongoing e-learning modules, and periodic UX/UI audits.]]>
