Depression in terminal illness: the need for primary care-specific research

Area of Science:

• Oncology
• Psychiatry
• General Practice

Background:

• Depression is common in terminal cancer patients, necessitating proactive screening and treatment per European Association for Palliative Care guidelines.
• Prevalence of depression in primary care patients with advanced cancer is not well-established.
• The applicability of existing palliative care depression guidelines for General Practitioners (GPs) is uncertain.

Purpose of the Study:

• To determine the prevalence of depression in a primary care population of patients with terminal cancer.

Main Methods:

• A two-stage community prevalence survey was conducted in UK primary care practices.
• Adult patients with advanced metastatic cancer were assessed using the Edinburgh Depression Scale (EDS) for initial screening, followed by diagnostic assessment with the revised Clinical Interview Schedule for those at high risk.
• Weighted prevalence estimates were calculated.

Main Results:

• The final sample comprised 70 patients with a response rate of 47.9%.
• The prevalence of depression was found to be 4.1% (95% confidence interval 0-8.8%).
• The sensitivity and specificity of the EDS screening tool were lower than anticipated in this population.

Conclusions:

• The observed depression prevalence was lower than anticipated based on prior palliative care research.
• Screening tool performance varied in this primary care population, suggesting limitations for direct application of palliative care findings.
• There is a need to develop an evidence base for primary palliative care to ensure appropriate clinical management of depression in advanced cancer patients within primary care settings.
