What we know
Prevalence of many diseases increases with age so many older people have more than one illness (comorbidity). Comorbidity is associated with poorer quality of life and increased risk of frailty. Frailty with ageing and comorbidity can make prognostication become difficult. Care planning discussions may be beneficial in recognising the need for palliative care, and reducing burdensome medication and treatments. Prioritising treatments requires an assessment across all health issues with respect for a person’s wishes.
