title: Using the MEDLINE database to study the concept of urinary tract infections in different domains of medicine.
abstract: As a way of exploring differences between medical domains regarding management of urinary tract infections, we investigated the MEDLINE database for differences in indexing patterns. Further, our intention was to assess the MEDLINE database as a source for studying medical domains. We examined the use of main headings, subheadings and the level of main headings in six medical domains that manage urinary tract infections. Many intuitive but also some counterintuitive results were found indicating that the MEDLINE database is difficult to use for studying medical domains mainly due to unclear semantics both in the headings and the indexing process, which results in variability in indexing. This variability probably hides significant results. We also conclude that the differences found indicate that in addition to differences between domains, there are also large variations within domains.
