The comorbidities were not simplified as an index because each comorbidity affected outcomes (length of hospital stay, hospital changes, and mortality) differently among different patients groups.
Komorbiidsusi ei lihtsustatud indeksiks, sest iga komorbiidsus mõjutas tulemeid (voodipäevade pikkus, haigla muutmised ja suremus) eri patsientide rühmades erinevalt.
