Toward Innovation and Policies: Mapping the Demand of Orthopedic Implants in Public Hospital Margono Purwokerto, Central Java, Indonesia

Abstract

Most of the needs for orthopedic implants in Indonesia are met by the imported product. So that innovation is needed to produce local products that suit the needs of the Indonesian people. The first step before innovating is the need analysis. It is necessary to map and forecast certain implant products to understand which products that are important to be developed before they become a national innovation. In addition, there has not been an article yet that reported data regarding implant product and their forecasting. The main objective of this research is to capture the actual demand product by mapping and forecasting the orthopedic implants in a public hospital. The mapping process was carried out using the descriptive analysis method to organize and summarize the data to get more information about the orthopedic implants that were widely used. In addition, the mapping process is also carried out using the double moving average method to see the trend of demand for orthopedic implants in the future. The data used in this research was the number of orthopedic implants used by the Margono hospital for five years starting from 2016 to 2020. Based on the collected data, forty-two varieties of orthopedic implants had been mapped regarding implant demand. Furthermore, twenty-two of forty-two implants had been analyzed based on several applications that always appeared within five years. This research type of implant is classified into five categories which are screw, plate, wire, rod, and prosthesis. It is found that cortical screw, straight plate, K wire, rod union, and bipolar cemented were noted as the highest demand implant represent their category. The demand forecasting process is carried out for cortical screw, K wire, and rod union. By using the double moving average method and MAPE for measuring the accuracy, it was found that the method has a significant result because the MAPE value is still quite good. The value of MAPE for cortical screw, K wire, and rod union are 0.3985, 1.0726, and 0.4332, respectively. The trend of increasing demand occurs in the product cortical screw and rod union. This data could perform as the recommendation and references leading to the research road map, especially in the orthopedic research field in Indonesia.
