The exact aetiology of the cause of death (COD) remains unknown for a high proportion of deaths caused by infectious diseases. Complete diagnostic autopsy (CDA) is considered the gold standard to determine COD, but it is often not used in low and middle-income countries (LMIC), including Vietnam, for a variety of reasons. One alternative is minimally invasive tissue sampling (MITS). This study was part of a larger project to explore the perceptions of MITS in Vietnam to provide recommendations for its potential implementation. We collected in-depth interviews and focus group discussions that explored MITS acceptability from 96 participants, including key informants, healthcare workers, community stakeholders, and people who had family members pass away recently. Participants highlighted the minimally invasive nature as the most considerable strength of MITS that could make it acceptable in Vietnam compared with CDA. However, participants still had concerns including the accuracy of the technique, the potential damage on the body, and the potential conflicts MITS results could have with original clinical diagnoses. Overall, the hypothetical acceptability of MITS was not clear-cut. It is imperative to consider acceptability before implementing new medical procedures into a given context, especially when it revolves around death, dying and the body.
