The decision as to whether these patients should be treated in ICUs is reached without clear guidelines. We therefore conducted a study with the aim of identifying triage criteria and factors associated with in-hospital mortality in this population. Methods All mechanically invasive ventilated elderly 65 medical patients in the hospital were included in a prospective non-interventional observational study. Results Of the 579 ventilations 283 were done in ICUs compared with 296 in non-ICU wards. The percentage of ICU ventilations in the 65 to 74 75 to 84 and 85 age groups was 62 45 and 23 respectively. The decision to ventilate in ICUs was significantly and independently influenced by age Odds Ratio OR P and pre-hospitalization functional status by functional independence measure FIM scale OR P . Inhospital mortality was in ICUs compared with in non-ICU wards P but the rate was not independently and significantly affected by hospitalization in ICUs. Conclusions In Israel most elderly patients are ventilated outside ICUs and the percentage of ICU ventilations decreases as age increases. In our study groups the lower mortality among elderly patients ventilated in ICUs is related to patient characteristics and not to their treatment in ICUs perse. Although the milieu in which this study was conducted is uncommon today in the western world its findings point to possible means of managing future .
