Building A Health Care Decision Support System For Developing Nations
Developing countries are using technology to modernize their industries, and the healthcare industry is no exception. Their governments, healthcare ministries, and public health officials are utilizing IT solutions to improve health outcomes, and International Health and Human Services (HHS) are also involved, such as the World Health Organization, the International Red Cross, and U.S. agencies such as USAID. Some of the HHS organizations are utilizing technology to improve program effectiveness and to audit their own work in the field. One such organization is utilizing a cutting-edge ontological engineering software Decision Support System, or DSS, (a vector control software) to determine potential healthcare issuesy and also measure the impact of disease control initiatives. This article describes the challenges and opportunities in building a healthcare DSS for developing nations. It also outlines how such nations are fusing their healthcare needs and ontology programming with their infrastructures (or lack thereof in various places) to accomplish desired outcomes. Ontologically Engineered software To meet the requirements of a large international HHS, TerraFrame, a software company based in Colorado developed an ontology-based DSS that is a vector control software that's an ontology-based platform with an integrated Geographic Information System (GIS) designed to be used for disease management-related decision making in developing nations. Its initial release was developed for a prevalent disease (malaria) in an African country. However, it is currently being expanded to address numerous diseases in multiple countries. The system is used to determine the disease footprint in a region so that remedial initiatives can be undertaken by the local public health officials, both proactively and reactively. The HHS also utilizes the product as an audit tool to determine an initiative’s effectiveness and to refine the subsequent iterations of the program based on prior results. The disease control initiatives include a wide range of measures such as the use of insecticide sprays. The DSS uses ontological programming principles (of "semantic" technologies) to model geographic, entomological, and insecticidal nomenclature. Standardization of insect related terminology allows data from multiple organizations to be effectively combined and queried. Additionally, since terms have hierarchical relationships, the technology allows for automatic categorization and grouping of related data. As new terms are added, ontology programming allows queries to automatically include them. This provides the healthcare DSS with a high degree of flexibility, as terms and relationships between terms can change and adapt dynamically in the field to accommodate new requirements. Furthermore, the geographic ontology standardizes terms for geographic features. This ensures data interoperability and allows for the GIS system to work, even in cases where the exact longitude and latitude of a data point is not known. The DSS uses GIS to capture, store, and analyze data associated with geographic locations in order to generate maps as a visual tool. A map consists of one or more layers, with each layer defined by a query created in the DSS. The layers can be overlaid and color-coded into meaningful representations of relationships and correlations between the data and geographic locations. These custom-generated maps with vector control software greatly assist public health officials in making informed decisions regarding disease control. This ontologically engineered product is capable of providing reports and query results using local data alone or data aggregated across geographic and governmental hierarchies. For example, an end user can query the system and utilize data from healthcare facilities at a village, city, district, state, or regional level—as well as a countrywide level. The international health organization referenced above expects the DSS data to be collected and utilized at all levels of the African nation.
