Reliability of the Service Trip Audit Tool to assess the quality of short-term medical missions

We aimed to assess the adherence of short-term medical missions (STMMs) operating in Latin America and the Caribbean (LAC) to key best practices using the Service Trip Audit Tool (STAT) and to calculate the inter-rater reliability of the data points. This tool was based on a previously published inventory of 18 STMM best practices.

Programme administrators and recent volunteers from 335 North American organizations offering STMMs in LAC were invited to complete the STAT anonymously online. Adherence to each of 18 best practices was reported as either 'yes', 'no' or 'not sure'. Fleiss' κ was used to assess inter-rater agreement of the responses.

A total of 194 individuals from 102 organizations completed the STAT (response rate 30.4%; 102/335 organizations) between 12 July and 7 August 2017. Reported adherence was >80% for 9 of 18 best practices. For 37 non-governmental organizations (NGOs) with multiple raters, inter-rater agreement was moderate to substantial (κ>0.4) for 12 of 18 best practices.

This is the first study to evaluate adherence to STMM best practices. Such an objective evaluation will be valuable to governments, volunteers and NGO donors who have an interest in identifying high-quality partners. Assessment and monitoring of STMMs through self-audit may be foundational steps towards quality improvement.
