Cardiac arrests in a geriatric unit.

The outcome of cardio-pulmonary resuscitation within an acute geriatric unit was studied in 95 patients (mean age 77 years, range 65-90) who were involved in 106 consecutive cardio-respiratory arrest calls. In 58 patients (61%), initial resuscitation was unsuccessful and a further 21 (22%) died later in hospital. Fourteen patients (15%) were alive 3 months after hospital discharge, a success rate comparable to that of published series in younger patients. The probability of successful resuscitation was greater in patients in the High-dependency Unit, and ventricular fibrillation and a short duration of arrest were confirmed as good prognostic factors. Age had no influence on outcome. Although subjective levels of psychological and physical disability of survivors at 3 months were low, their domestic and social life was often excessively restricted. Selective, but positive, use of cardio-pulmonary resuscitation within acute geriatric units will benefit a significant minority of patients, but there is also a need for further measures to reduce unnecessary disability in long-term survivors.
