Turnbull et al studied patients who had an emergency readmission of a critically ill patient based on polypharmacy. This number of drugs that a person is taking can help to identify a patient at high risk for emergency readmission. The authors are from University of Edinburgh, Queen Margaret University Edinburgh, Edinburgh Napier University and the University of Dundee.
