Older Cancer Patients With Depression Can Be Treated

Study says collaborative approach in primary care settings is feasible

Depression in older cancer patients is very common, and has debilitating effects on their quality of life both during and after treatment. University of Washington researchers are showing that there are ways to better this situation. The results of their study were just published online in Springer’s Journal of General Internal Medicine.

“Little is known about the optimal approach to treating depression in this population, and older cancer patients are less likely to be treated for their depression than are younger cancer patients,” said Dr. Jesse Fann, University of Washington associate professor of psychiatry and behavioral sciences.

Fann and his colleagues evaluated the effectiveness in older, depressed cancer patients of an intervention called Improving Mood-Promoting Access to Collaborative Treatment (IMPACT), in comparison to a similar set of patients receiving usual care. All participants had either major depression or a type of chronic depression called dysthymia, or a combination of both.

IMPACT participants worked with a depression care manager in their primary care clinic for up to a year. Under the supervision of the patient’s primary care provider and a psychiatrist, the care manager offered the patient support in taking anti-depressants if prescribed by the primary care provider, education about depression, care coordination and structured counseling sessions that helped the patient engage in pleasant activities and that taught problem-solving skills.

The intervention was tested in 18 primary-care clinics in five states in the USA. The clinics served a variety of different socio-economic, geographic, and ethnic populations.

At the end of six months, 55 percent of the patients in the IMPACT group and 34 percent of the usual care participants showed a 50 percent or greater reduction in their depression symptoms. The IMPACT participants also had higher remission rates from depression, more depression-free days, less fatigue, a better quality of life, less functional impairment and fewer thoughts of death. Many of these benefits persisted during the one-year follow up period after the intervention was completed.

“Among the functional impairments older cancer patients can experience with depression are fatigue and thinking problems, such as forgetfulness, feeling mentally slowed down, and having difficulty concentrating or solving problems. Decisions that used to be straightforward or easy for them have become challenging,” Fann explained.

Based on their findings, the researchers concluded that the IMPACT collaborative care program is feasible and more effective than standard care in managing depression among older cancer patients in primary care, and is widely applicable.

Obtaining effective treatment for depression is vital, explained Fann, because of the serious, troubling effects depression has on many cancer patients: A depressed person may feel less motivated to exercise or eat well, to carry out treatment plans or be an active participant in their care. The risk of suicide is twice as high among older cancer patients compared to the general population, and the risk is even higher with older age. Some depressed patients question if cancer treatment is worth it, even if they don’t plan to end their lives. Patients may rebuff family and friends, and feel incapable of making arrangements for the future.

“The elderly are the largest segment of our population with cancer, and older cancer patients are becoming a significant segment of primary care practice,” Fann said. By supporting depression care in primary care settings, the authors of the study added, health-care providers can help older cancer patients truly benefit from advances in cancer treatment by improving their quality of life.
