Interactive computer program helps patients talk with their physician about depression
Core Elements in Responding to Mental Health Crises CE Course Three waiting-room interventions tested The new study involved nearly 900 patients and 135 primary-care clinicians at seven Northern California health-care sites. Prior to their medical appointments, patients were screened for depression. All patients were then randomized to view one of three interventions: •A video – similar to a public-service announcement – focused on recognizing depression and talking with doctors about symptoms •An interactive multimedia computer program that provided patients with instant feedback and information tailored to different levels of depressive symptoms and treatment preferences •A non-depression-related video on healthy sleep The clinicians did not know which intervention their patients viewed. Immediately after the patients' appointments, the researchers determined if the patients discussed depression with their clinicians and whether they left with prescriptions for medications to treat depression and if they received a referral for mental-health services. Help for the most depressed The results showed that patients with baseline depression who either watched the informational video or used the computer program were nearly twice as likely as control subjects to request information about depression during their appointment. Those who used the interactive computer program were significantly more likely to receive a prescription or referral for depression (26 percent) than were those who viewed either the depression video (17.5 percent) or the video on sleep (16.3 percent). The computer program had the greatest impact on patients who were most depressed, according to the baseline screening. The investigators also studied the effects of the interventions on people who were not likely to be depressed according to the baseline screening. Among these patients, rates of prescribing and referral were low (about 5 percent) and did not differ by intervention group. According to Richard Kravitz, UC Davis professor of internal medicine and lead author of the study, it is important for public-health interventions to avoid inadvertently expanding unnecessary treatments that can do more harm than good and waste health-care resources. "We were concerned that the interventions could lead to treatment for depression for those who do not actually have it," said Kravitz. "Our interactive computer program, however, increased help for those who needed it the most without increasing treatment for those who didn't." According to Jerant, this study is the largest to compare "targeted" versus "tailored" interventions for stimulating people with depression to seek and accept treatment. Targeted interventions, such as the informational video used in the study, use terms and images most likely to resonate with the target audience, based on specific demographic factors. Four different versions were used in this study, targeted toward gender and income levels. The video took about three minutes to watch. Tailored interventions, such as the study's interactive computer program, integrate patient-specific answers to deliver information and guidance. The program used in the study, developed by the study investigators, prompted users to answer questions about symptoms of depression, informed users as to whether or not they were likely to be depressed, and provided guidance depending on the users' specific needs and interests. Patients assigned to the computer program spent about two to 15 minutes on it, with a median of five minutes. Kravitz speculated that the informational video did not work as well because, like a television commercial advertising a medication, it may require multiple repetitions to be effective. In contrast, the interactive computer program quickly provided a high level of personalization, which may account for its higher degree of effectiveness with a single use. The UC Davis investigators intend to further refine and study the interactive computer model to identify patients who need to receive more extensive treatment for their depression Professional Counselor Continuing Education ### Other UC Davis investigators on the study were Peter Franks, Daniel Tancredi, Christina Slee, Robert Bell, Debora Paterniti, Camille Cipri, Ana-Maria Iosif, Andrew Hudnut, Simon Dvorak and Charles Turner.
