A retrospective review of 274 patients who received in-hospital cardiopulmonary resuscitation was performed to determine whether age is independently associated with survival to discharge. Eighty-two (29.9 per cent) of the 274 patients were resuscitated initially, but only 25 (9.1 per cent) were discharged alive. Survival to discharge was significantly poorer in patients aged≥70 years (6/175; 3.4 per cent) than in patients<70 years old (19/99; 19.2 per cent) (p<0.001). Severity of illness, assessed by the number of diagnoses and a multifactorial morbidity index, did not differ between the two age groups. The best results were obtained with witnessed arrests, ventricular arrythmias and resuscitation lasting less than 5 minutes; however, elderly patients were less likely to be resuscitated in all circumstances. Age (r=−0.31,p<0.001) and the morbidity indexr=−0.18,p<0.05) were independently associated with survival by multivariate analysis.These results indicate that advanced age is an important independent determinant of survival after resuscitation. This should be taken into consideration when making in-hospital resuscitation deci
