Minimally Invasive Autopsy Methods in Global Child Mortality
Summary
Minimally invasive autopsy (MIA) methods have emerged as a transformative approach for determining causes of death in stillbirths and children under five, particularly in low-resource settings. By combining targeted needle sampling of key organs with microbiological, molecular and histopathological analyses, these techniques offer high diagnostic yield while avoiding the cultural and logistical barriers of full autopsy. Implemented within surveillance networks and clinical studies, MIA approaches have demonstrated substantial concordance with conventional autopsy findings and have clarified the complex interplay of infections, perinatal complications and malnutrition in child mortality. Their increasing use has generated granular data on the aetiology of neonatal sepsis, pneumonia and birth defects, informing vaccine development, antimicrobial guidelines and maternal-newborn care strategies. Moreover, high community acceptability and rapid turnaround times make MIAs a pragmatic tool for real-time mortality surveillance and tailored public health interventions worldwide.

Minimally Invasive Autopsy Methods in Global Child Mortality publication trend
The graph below shows the total number of articles in minimally invasive autopsy methods in global child mortality across all publications each year (not limited to Nature Index journals).
Technical terms
Minimally invasive autopsy (MIA): A post-mortem procedure using needle or trocar biopsies of key organs and fluids to establish cause of death without full dissection.
Verbal autopsy: Structured interviews with caregivers or witnesses about symptoms and circumstances preceding death, used to support cause-of-death determination.
Nosocomial infection: An infection acquired in hospital, often implicated in hospital-acquired pneumonia or sepsis revealed by post-mortem sampling.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
