About the HTAi vortal

The HTAi vortal aims at organising at one place information of interest about Health Technology Assessment (HTA).

The HTAi Vortal was first launched in 2005 as a section of the HTAi website; a Google custom search engine was added in 2007. The HTAi Vortal was maintained until 2010 by Elaine Alligood and Megan Brenshaw and listed over 410 resources organised into 12 categories.

In 2010, the management of the Vortal was taken over by a new editorial team: Patrice Chalon and Sigrid Droste. Users were surveyed in order to evaluate the future development the Vortal should receive. As a result, a new infrastructure was developped: the Vortal version 2 was launched in 2012 as a dedicated website based on the Open Source Content Management System Drupal with a dedicated module allowing to manage references in a very profesionnal way. The Vortal version 2 also introduced a new structure by splitting the former unique structure into 3 sections: HTA Producers and networks, Selected resources and Career developement.

In 2011, a new project developped within the IRG identified the Vortal as a good publication plateform for its output; SuRe Info became thus the fourth section of the Vortal.

In 2014, the Vortal extended the services offered by hosting the first "custom bibliography" developed by another HTAi ISG.

In 2015, new editorial teams joined the Vortal.

Publications fulfilling the SuRe Info inclusion criteria receive a structured abstract along with a brief critical appraisal prepared by one SuRe Info information specialist and checked by another. The key messages from the appraisals are summarized into topic-specific chapters.

Organisation of SuRe Info

SuRe Info has two sections:

  1. Information on general search methods common across all health technologies;
  2. Methods to use when searching for specific aspects of health technologies. With the exception of the chapters on Diagnostic accuracy and Qualitative research, this section is based on the domain structure of the HTA Core Model®, an on-going project to standardize the structure of HTA developed by EUnetHTA.
