Medical Terminology Server for the Hospital of Clinics of Paraguay using Apache Lucene and the UMLS Metathesaurus

The current process of medical terminology coding in health standards at the Hospital of Clinics of Paraguay is performed by physicians, normally interns or residents. They search the medical terminology code in impressed coding manuals or in internet by using their cell phones. This search process takes a lot time to be done during the medical consultation. This work proposes and evaluates a friendly medical terminology server thought web services, using Apache Lucene, as a search engine library, and the Metathesaurus of Unified System of Medical Language (UMLS), as an information source. The server is developed for Spanish speakers. Results show that physicians can find medical terminology code with the terminology server, using friendly or familiar terms, 18 times faster than with the current search process. The user satisfaction degree is ``Good” according to an adjective rating of the System Usability Scale (SUS). In addition, a comparison with a search engine of medical terminology called Metamorphosys shows that the implemented terminology server is quite competitive and it responses in similar average time
