title: Use of a depression screening tool and a fluoxetine-based algorithm to improve the recognition and treatment of depression in cancer patients. A demonstration project.
abstract: Helping oncologists to identify and treat depression is an important step in improving the overall care of people with cancer. In previous work performed in our community-based, ambulatory oncology outreach network, we validated a depression screening tool, put into place depression screening programs, and taught oncologists how to follow up on screening with brief, reliable clinical interviews. Subsequently, we provided these oncologists with a fluoxetine-based antidepressant algorithm to follow for the treatment of their depressed patients. In this article, we report on the initial experience identifying and treating 35 ambulatory oncology patients who were screened with the Zung Self-rating Depression Scale (ZSDS). Structured follow-up interviews by their oncologist determined whether the patients qualified for a diagnosis of a major depressive episode. These patients then received 1 of 4 treatments based on the algorithm (no treatment, fluoxetine alone, fluoxetine plus bedtime doxepin, or fluoxetine plus methylphenidate). Patients were matched by their oncologist to a prototype patient for each treatment arm based on their symptomatic presentation (i.e., patients requiring a side effect minimization approach were to be placed on fluoxetine alone; patients who had significant insomnia, weight loss, or neuropathic pain were placed on the fluoxetine plus doxepin regimen; those with prominent fatigue were to receive fluoxetine plus methylphenidate). Patients were followed weekly for one month, and then every two weeks for two more months, with telephone assessments of their depression, associated symptoms and overall quality of life. Results suggested that oncologists most often chose the simplest regimen (fluoxetine alone) but that patients uniformly benefited in terms of improved mood and overall quality of life throughout the 12 weeks of follow-up. Our initial experience suggests that oncologists can be empowered to recognize and treat depression in their patients with a screen-and-intervene approach. Such an approach may benefit patients, and, if kept simple, can be incorporated into day-to-day care of people with cancer.
