Abstract
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
Highlights
Diagnoses are coded daily at the Hospital of Clinics of Paraguay using medical terminologies coded in health standards
Unified Medical Language System (UMLS) Metathesaurus is used as the source of information about biomedical concepts, which is quite complete and provides a large number of controlled or standardized vocabularies
[4] we describe several terminology standards and some terminology servers created to support the medical coding in electronic medical records
Summary
Diagnoses are coded daily at the Hospital of Clinics of Paraguay using medical terminologies coded in health standards. The Ministry of Public Health and Social Welfare of Paraguay established that medical diagnoses should be coded using the standard International Classification of Diseases Version 10 (ICD-10), since the World Health Organization recommends its use [1]. This standard provides statistical information on diseases or problems, which can be used for reporting and decision-making in the health area of a country or region [2]. Metamorphosys acts as a search engine and makes possible to navigate between the concepts of the semantic network and the metathesaurus. This search engine has four matching options for word search [3]:
