The scope for data collection by the GODT includes the 194 Member States in the six WHO regions: Africa (AFR), The Americas (AMR), Eastern Mediterranean (EMR), Europe (EUR), South-East Asia (SEAR) and Western Pacific (WPR).
A questionnaire is being used to collect information concerning organizational structures, legislative systems and activities related to organ donation and transplantation procedures. The questionnaire is annually distributed to the identified network of health authorities and officially designated individuals contributing to the global database.

The questionnaire covers three sections for organs, tissues and cells.

          - Qualitative data:          

                  Organizational structures:  Yes/No responses
                  Legislative aspects: Yes/No responses

          - Quantitative data:

         Donation and Transplantation activities (kidney, liver, heart, lung, pancreas, small bowel, multivisceral).

Analysis of the activity data
The questionnaire collects activity data for organs, tissues and cells, however since the pieces of information for cells and tissues are so far very limited, only information pertaining to solid organ donation and transplantation has been analyzed on a yearly basis. 

Calculation of estimates
National activity data is examined in both regional and global contexts. The annual study forms the basis of possible situational analyses for individual countries, and shows the utility of the GODT as a comprehensive tool by which these topics of international concern may be evaluated comparatively. 
Data are presented in absolute numbers and rates per million population (pmp). Unless otherwise indicated, data are for the last year indicated.
Source of indicators: The United Nations Population Fund report is used as the data source for estimates of population size, unless a more up-to-date figure is available from an official source. Figures for Human Development Index (HDI) are obtained from the United Nations Development Programme (UNDP).
Rates for the regions are calculated by applying denominator populations of those countries that were able to provide estimates of transplantation activity.
The analyses are done using descriptive statistics performed with SPSS software.
This work is being possible thanks to the contribution of information of the network of health authorities and officially designated focal points every year.
