Re: David Oliver: “Progressive dwindling,” frailty, and realistic expectations
‘Progressive dwindling’ or ‘terminal decline’ and end-of-life care.
David Oliver’s commentary highlights the some of the difficulties faced by geriatricians responsible for the care of frail older adults. Accumulating evidence shows that a key aspect of the frailty syndrome is its relation to adverse outcomes including hospital admissions, falls, fractures and mortality.1-4 Oliver adopts the terminology of ‘progressive dwindling’ to refer to the progressive and accelerating functional decline that may occur at the end-of-life in very old people. Other writers have referred to this process as one of ‘terminal decline’ or ‘terminal drop.’ 5 Empirical evidence of terminal decline has been reported for cognitive functioning, 6 and subjective health measures.7 Our recent study using electronic health records in people aged 80 years and over, revealed a substantial terminal decline in blood pressure in the final two years of life that was not observed in patients who did not die.8 Diehr and colleagues observed that ‘It is difficult to distinguish changes in health due to aging from those related to dying.’7 Researchers and clinicians should aim to determine whether these processes are distinguishable in order to improve end-of-life care for older people.
