Zapatero et al developed an index for prediction of readmission to the hospital for adults on an internal medicine ward. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple hospitals in Madrid.
SEMI is an acronym for Sociedad Espanola Medicina Interna.
