Payne et al reported the Cambridge Multimorbidity Scores. One model uses 37 conditions and second model with a subset of 20 conditions. The authors are from the University of Bristol, University of Cambridge, RAND Corporation and University College London at the Royal Free.
Outcomes:
(1) mortality
(2) primary care consultation
(3) unplanned hospital admission
