Using Facility-Location Models To Optimally Locate Hierarchical Community-Based Health Facilities In Davao City, Myra Silva, Michael Johnson
Michael P. Johnson
Alternative hierarchical location-allocation models are used to locate two types of community-based health facilities in Davao City relative to population locations. Accounting for factors such as politics and resource availability, different optimization approaches were implemented to locate a mix of health centers and nutrition posts across the rural and urban areas of the city. The results were evaluated based on operating costs, average travel distance and population coverage. Computational results revealed that, by optimally locating barangay health centers and health posts, the current level of public investment in the health delivery infrastructure can be sufficient to cover a significant proportion …

Objectives: This study sought to investigate user interactions with an electronic health records (EHR) system by uncovering hidden navigational patterns in the EHR usage data automatically recorded as clinicians navigated through the system’s software user interface (UI) to perform different clinical tasks. Design: A homegrown EHR was adapted to allow real-time capture of comprehensive UI interaction events. These events, constituting time-stamped event sequences, were used to replay how the EHR was used in actual patient care settings. The study site is an ambulatory primary care clinic at an urban teaching hospital. Internal medicine residents were the primary EHR users. Measurements: …
