Screening for depression among patients with multiple sclerosis: two questions may be enough.

BACKGROUND: Depression among patients with multiple sclerosis (MS) is common and has a significant impact on quality of life. As many as two-thirds of depressed MS patients receive no treatment for their depression. While guidelines for depression management suggest screening, the only validated screening tools are questionnaires, which have not been widely implemented in practice. This is the first study on the effectiveness of using two questions assessing mood and anhedonia (loss of interest or pleasure) in screening for major depressive disorder (MDD) in MS. METHODS: MS patients under the care of neurologists were recruited from a large health maintenance organization (HMO). The MDD module of the Structured Clinical Interview for the DSM-IV and screening questions was administered. RESULTS: Of the 260 participants, 26% met the criteria for MDD. Among patients with MDD, 67% received no anti-depressant medication. The MDD screen identified 99% (95% CI: 91-100%) of cases. DISCUSSION: A brief, two question screen is reliable in identifying MS patients with MDD. This suggests that asking these two brief questions could identify almost all MS patients meeting MDD criteria, with minimal numbers of false positives.

Treatment of depression for patients with multiple sclerosis in neurology clinics.

UNLABELLED: The objective of this study was to examine the adequacy of antidepressant pharmacotherapy in a sample of patients with multiple sclerosis (MS) treated by neurologists. METHODS: MS patients under the care of neurologists were recruited from a large health maintenance organization. Major depressive disorder (MDD) was diagnosed using a structured telephone interview. Antidepressant treatment data were obtained from the HMO pharmacy database. RESULTS: Study participants included 260 patients with MS treated by 35 neurologists. A total of 67 (25.8%) patients met the criteria for MDD. Among the patients with MDD, 65.6% received no antidepressant medication, 4.7% received subthreshold doses from their neurologists, 26.6% received doses at threshold, and 3.1% received doses exceeding threshold. DISCUSSION: Depression was undertreated by the neurologists treating this sample of patients with comorbid MS and MDD. Potential solutions are discussed.

Sex or survival: trade-offs between quality and quantity of life.

Patients with localized prostate cancer may be treated with either surgery (radical prostatectomy) or radiotherapy. Although controversial, many physicians believe that surgery offers a higher survival rate. However, the surgical treatment may also produce a higher rate of sexual impotency. Our study assessed how men value survival and sexual potency when asked to trade off one for the other. Using the treatment-choice technique, we interviewed 50 men aged 45 to 70 years without known prostate cancer. At hypothetical rates of survival (90% at 5 years for surgery) and impotency (90% for surgery and 40% for radiotherapy) representing published estimates, 32% of respondents were unwilling to trade off any survival, but 68% were willing to trade off a 10% or greater advantage in 5-year survival (by choosing radiotherapy) to maintain sexual potency. The median 5-year survival traded off was 10% (range, 0% to 80%). Willingness to trade off survival for sexual potency was significantly related to level of education, but not to age, interest in sex, frequency of sexual intercourse, or ability to achieve erection. We conclude that some men may choose treatment with lower long-term survival to increase their chance of remaining sexually potent. Because these men may be difficult to identify in clinical practice, physicians should thoroughly discuss both surgery and radiotherapy options with patients who have localized prostate cancer.
