TABLE 1. Six-step TCIM evidence map methodology.

Step

Activities

1 Search. Bibliographic search for TCIM scientific evidence must be carried out in electronic databases and complemented by manual search and/or indication of TCIM specialists collaborating on the project.

  • Identification and selection of information sources (databases and journals) that will be consulted;
  • Development of electronic search expressions according to the selected databases and the selected TCIM practice;
  • Conducting manual search and/or indicating revisions in TCIM, not identified in electronic search;
  • Metadata exportation of bibliographic records retrieved in the bibliographic search (electronic and manual);
  • Importing metadata from bibliographic records into a bibliographic reference manager (e.g., Endnote, Mendeley); and
  • Documentation with a detailed description of all bibliographic searches performed.

2 Selection. Scientific evidence (scientific articles) identified in the bibliographic search will be evaluated according to previously defined criteria.

  • Analysis of the articles identified in the first stage to confirm compliance with the predefined inclusion criteria;
  • Classification of selected evidence in pairs, preferably with blinding, using software (e.g., Rayyan);
  • Evaluation and classification of studies by quality criteria (e.g., AMSTAR 2 in case of systematic reviews).

3 Categorization. Data from the studies included in the previous stage will be extracted considering previously defined categories.

  • Definition of intervention categories (depending on each TCIM practice) and outcomes (e.g., mental health, pain, cancer) that will be used to map selected review studies;
  • Data extraction such as: Full Text (website link); Citation (complete reference), Population; Database ID; Focus Country (countries in which studies were carried out); Publication Country (country in which the article was published); Publication Year;
  • Analysis about included studies considering information provided by authors and quality criteria: Effect (positive, potential positive, inconclusive, potential negative, negative); Level of confidence (high, medium, low); Type of Review (systematic review, narrative review, scoping review, mixed methods review, protocol, meta-analysis, metasynthesis, etc.); Review Design (clinical studies, randomized controlled studies, observational studies, mixed studies, etc.); Study Design (effectiveness, safety, cost).
  • Review and adjustment of categories.

4 Informetrics. Development of informetric analysis takes place from metadata of review studies identified and registered in the databases.

  • Definition of indicators that will be generated for informetric analysis;
  • Performing the extraction, transformation and loading processes for metadata of the selected studies;
  • Development of visualizations of informetric data to support analysis of the defined indicators; and
  • Integrate visualizations of informetric data in evidence maps and/or graphs from Tableau software.

5 Evidence map. Creation and publication of evidence maps consists of graphically representing the evidence found, analyzed, and categorized, in addition to linking with bibliographic records and full texts (when available) of evidence studies.

  • Identification of main contents (highlights) to produce maps and/or graphics;
  • Creation of graphic design elements of maps and/or graphics;
  • Inclusion of content in maps and/or graphics with links to bibliographic records in the corresponding databases; and
  • Publication of maps and/or graphics in the VHL TCIM Americas and other selected portals.

6 Gaps. Based on analysis of the studies identified and analyzed, a report or scientific article should be organized in order to demonstrate evidence gaps and redundancy (multiple studies on similar issues) related to TCIM, contributing to establishment of national research priorities among research agencies and researchers.

  • Definition of analysis criteria for the studies identified and selected for TCIM;
  • Quantitative analysis of studies identified and selected using the defined criteria;
  • Preparation of reports pointing out evidence and redundancy gaps for TCIM; and
  • Publication of reports.
