Short-term medical volunteer work via a nongovernmental organization is a popular tool for students in the health care field to gain experience, while further providing communities that normally lack health care options the opportunity to receive free care. One such organization, VIDA Volunteer Travel, has been successful in implementing this model in Central America. However, organizations of this form have not been evaluated for effectiveness or improvement. This exploratory study examines the effectiveness of VIDA based on six qualifying characteristics that make up a successful NGO. The researcher conducted in-depth, semi-structured interviews with 21 individuals, including VIDA staff members in Costa Rica and Nicaragua, health professionals working for VIDA, local community leaders, and volunteers participating in VIDA's programs. Summaries and quotes of these interviews were uploaded and analysed using Atlas.ti to identify common words and themes from the interviews. Informants frequently identified the organization as sustainable, both from a fiscal and ecological standpoint. The organization also successfully managed volunteers, although post-trip follow-up was lacking. Adherence to the mission statement and distribution of supplies allowed for improved organization and successful structure of the organization. Education and health promotion was also emphasized, although implementation of this education into the communities was lacking. Collaboration with the community and volunteers allowed for stringent, successful treatment to be given to patients, and ethical guidelines set up by the organization allowed for self-governance and improvement of the NGO. This study suggests future research opportunities for the organization, to evaluate its own impact and opportunities for improvement. Furthermore, suggestions are addressed that allow the organization to improve upon its well-implemented infrastructure, and allow for future organizations to use VIDA as a model for improvement.
