Study finds high suicide risk among older adults with depression

A recent study conducted across four psychiatric departments in Madrid, Spain, examines the relationship between depression subtypes, suicidality, and healthcare costs in older adults. With depression rates on the rise globally, particularly among elderly populations, understanding these factors is critical for improving mental health outcomes.

The study analyzed data from 2,868 patients aged over 60 who were either in inpatient or outpatient psychiatric care. Of these, 550 were evaluated for suicidal ideation and attempts using the Columbia Suicide Severity Rating Scale (CSSRS). The average age of participants was 70, with a majority (75.9%) being women.

Key findings reveal that 83.2% of the patients assessed reported suicidal thoughts, and 7.3% had attempted suicide in the month prior to the evaluation. The research highlights that healthcare costs differed among various depression subtypes, with patients diagnosed with bipolar depression incurring higher costs compared to those with dysthymia. Specifically, costs were 2.6 times higher for bipolar depression than for dysthymia, but no significant difference was found when compared to major depressive disorder (MDD) or recurrent depressive disorder.

The study also identified risk factors associated with suicide attempts. Recent attempters had a significantly higher lifetime history of attempts (odds ratio of 8.434). Additionally, individuals aged between 71-80 years and those over 80 years exhibited higher odds of suicide attempts (odds ratios of 3.433 and 3.322, respectively). The presence of recurrent depressive disorder increased the risk of suicide attempts by 3.529 times.

The findings underscore the importance of targeted health policies aimed at older adults with depression. By focusing on this demographic, healthcare systems can work towards reducing suicide rates and improving mental health services for the elderly population. Understanding the costs associated with different depression subtypes may also guide resource allocation and treatment strategies.

This research adds valuable data to the ongoing discussion about mental health in aging populations, emphasizing the need for effective interventions and support systems. As the burden of depression continues to grow, addressing these issues becomes increasingly vital.
