The authors make a valid point about the large amount of work that remains before “big data” and machine learning yields practical use to patient care. There indeed needs to be more knowledgeable personnel to collect, curate, and clean data before they could be used to train models of any relevance.
However, even more basic than these are thresholds of acceptability and behavioural changes that clinicians need to cross before data tools get used. Semmelweis discovered the importance of handwashing in the mid-1800s, and still today, in the 21st century, infection control audits need to be enforced on clinicians to encourage hand hygiene in clinical areas.
