10 Years of RIPSA – A unique initiative in Latin America
[RIPSA by J. B. Risi Jr. – interview]
RIPSA was established 10 years ago as an inter-institutional cooperation
initiative to support the use of information in the national health system
management. This was justified due to the fragmentation of the existing information
systems and to insufficiency of regular processes to perform general analysis of
health situation and its trends.
The first step was to assembly a set of basic indicators suitable to this type of
analysis, with a clear definition of its concepts and meanings, data sources and
calculation methods, as well as its uses and limitations, and also available and
recommended analysis categories. Through a collaborative work process involving
the primary institutions involved, this set of basic indicators and data is annually
reviewed, updated and made available in an easily-accessed database on the
Internet.

how to search
scientific literature
for 101 basic
indicators ?
DeCS/MeSH for indexing literature
• DeCS – the Portuguese acronym for Descritores em
Ciências da Saúde, ie, Health Sciences Descriptors

–
update frequency idem MeSH
currently available in Portuguese, Spanish and English
provides for Public Health, Homeopathy, and Science and Health terminology
allows meta searching, ie, multiple IS can be searched by a single search strategy
allows multilingual searching to literature
Controlled multilingual vocabulary created by BIREME in 1982, fully compatible with MeSH
serves as a controlled (unique, standard) vocabulary for indexing scientific and technical healthrelated literature
permits searching by subject (concepts), independently of the language
• natural language used in document titles, abstracts and full texts is ambiguous and
therefore leads to long/complex search expressions, lack of specificity and unreliable
results
– DeCS/MeSH hierarchical codes allow for exploding (searching) all terms of
a conceptual hierarchy (branch of the hierarchical tree)
Information Science clusters
A distribuição do conhecimento
científico público em informação, comunicação e informática em saúde
indexado nas bases de dados MEDLINE e LILACS. Ciência e Saúde Coletiva, 2007.
Abel L. Packer, Adalberto O. Tardelli, Regina C. Figueiredo Castro.
• presents the distribution of the international regional and national scientific output in the area
of
health information and communication, indexed in MEDLINE and LILACS databases
between 1996 and 2005.
• the selection of articles of this knowledge
area was based on the hierarchical structure
of the vocabulary used in these databases for Information Science.
• four specific domains were determined: health information, medical informatics, health
scientific communication and health communication:
1. Informação em saúde - Informação epidemiológica, vigilância epidemiológica, estatísticas vitais,
administração de serviços
2. Informática em saúde - Informática médica, informática em saúde, e-health
3. Comunicação científica - Informação científica, comunicação científica, documentos, serviços de informação,
bibliotecas
4. Comunicação em saúde - Divulgação e comunicação pública, comunicação em saúde, material educativo, educação
… applies open Literature-based discovery approach to find
the concepts occuring in a cluster of articles
