A study has revealed high rates of depressive symptoms in the last year of life as well as differences in the burden of depressive symptoms. 

Researchers of the interview-based study published in the Journal of the American Geriatrics Society concluded that a public health approach must be taken to screen for and appropriately treat symptoms of depression across the lifespan.

It included 3,274 individuals who died by the end of the study and found that depression symptoms increased gradually from 12 to 4 months before death and then escalated from 4 to 1 months before death. Women, younger adults, and non-white adults all had higher rates of depressive symptoms.

Individuals with cancer reported escalating rates of depressive symptoms at the very end of life, while individuals with lung disease and impairments in activities of daily living demonstrated persistently high rates throughout the year before death.

"Psychological symptoms are important to address throughout the lifespan, but especially in the context of serious or chronic illness in order to reduce suffering and distress and help individuals experience a 'good death,'" said lead author Elissa Kozlov, PhD, of the Rutgers Institute for Health.

"More research and policy work are needed to address the lack of skilled geriatric and end-of-life mental health providers, limited reimbursement structure for psychological care, and gaps in adapting and disseminating evidence-based non-pharmacological interventions for adults with limited life expectancies."
