Choosing life support for suddenly severely ill elderly relatives

To determine whether relatives are more likely to request intensive treatment for elderly relatives than the elderly parents would wish for themselves, and to explore the reasons which drive this behaviour.

A potential end-of-life scenario was presented to 30 elderly people and also to their next generation relative who could be required to be a surrogate decision-maker for their elderly relative in the future. A semi-structured interview (which was designed to avoid the use of leading questions) was undertaken by a trained psychology researcher to ascertain the views of the subjects with regard to treatment choices and the motivation underlying these views.

Of the potential patients, 83% reported that they would not want intensive treatment in the hypothetical situation. However, while 76% of surrogates also stated that they believed that treatment was inappropriate, all of the surrogates elected to initiate treatment. The need for time to get the family together, the need to reach family consensus and the need to be more certain of prognosis, were major influences which led the surrogates to request initiation of intensive treatment.

Better understanding of the factors which motivate surrogate decision-makers may help the development of measures to avoid the inappropriate use of high technology treatment at the end of life and to achieve outcomes which better match the wishes of the patients whom we treat. Measures which encourage elderly, chronically ill patients to determine their treatment (e.g. by advance directives), rather than delegating the responsibility to relatives, are likely to result in less demand for inappropriate intensive care treatment.
