Unlocking Health Clues for Aged Care Residents with Simple Throat Swabs

**Flinders University researchers** have discovered a promising approach to identifying **health vulnerabilities** in older adults residing in long-term aged care. This study, led by PhD candidate **Sophie Miller**, highlights the potential of using a simple throat swab from the **oropharynx** to gather insights into the overall health of aged care residents. Traditionally, vulnerability assessments have relied on physical measures such as grip strength. However, this research introduces a **biological marker**: certain throat bacteria that could indicate greater health risks. The study, conducted across **190 aged care residents** in South Australia, revealed a significant finding. The **presence of Staphylococcus aureus** was linked to poorer health and increased mortality risk, independent of obvious infections. Residents with this bacterium were **almost ten times more likely to die** within a year. Even after considering existing health conditions and medications, the association between **S. aureus** and mortality remained robust. **Professor Geraint Rogers** emphasized that the results highlight the importance of using microbial markers to augment traditional health assessments. While the findings are promising, further research is needed to confirm these outcomes and understand potential long-term applications.
