Summary

This observational study asks whether older patients placed under isolation precautions in the hospital are more likely to develop delirium or experience cognitive decline. Researchers will compare isolated patients aged 70 and older with similar non-isolated patients, tracking delirium twice daily and testing thinking skills six weeks after discharge. The goal is to understand whether isolation itself poses a risk to mental function in older adults.
