Two digital health studies pointed to different, practical pathways for improving outcomes and quality. A randomized trial in Germany found that pre-visit computer-assisted history-taking plus copy-ready summaries drove documentation completeness in inflammatory rheumatic disease screening from 46.9% to 100%, with high patient and physician acceptance. Separately, a Japan trial evaluating an AI chatbot for home-visit nurses reported lower mental effort and higher confidence during simulated heart failure cases, highlighting workforce-support potential when nurses work alone. Both studies emphasize that AI value hinges on workflow integration—structured capture and human-in-the-loop designs—rather than standalone model performance.
