Factors predicting change in frequency of heavy drinking days among alcohol-dependent participants in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

Aims: To discover the predictors of change in the frequency of heavy drinking (HD) over a 4-year period in alcohol dependent (AD)-individuals identified in the general population, namely, among participants of the US National Epidemiologic Survey on Alcohol and Related Conditions interviewed at Wave 1 (2001-2002) and at Wave 2 (2004-2005).

Methods: The study cohort included subjects meeting DSM-IV criteria for AD in the past year at Wave 1 (n = 1484), who were present at Wave 2 (n = 1172) and had complete data on factors of interest (n = 1123). Frequency of HD was defined as the number of HD days (HDD) (≥5 drinks per day for men and ≥4 for women).

Cost-effectiveness of antidepressant medications.

BACKGROUND: Antidepressant medications have been shown to effectively relieve symptoms, improve interpersonal and occupational functioning and reduce disability from coexisting medical conditions. Although the newer selective serotonin reuptake inhibitors (SSRIs) have improved tolerability, are easier to take and are associated with longer lengths of therapy when compared with the tricyclic antidepressants (TCAs), the relative cost-effectiveness of alternative antidepressants remains unclear. AIMS OF THE STUDY: This study seeks to determine (i) the probability that relapse or recurrence of depression can be prevented by appropriate antidepressant choice, (ii) the cost associated with relapse or recurrence of depression and (iii) the relative cost-effectiveness of alternative antidepressants.

Antidepressant treatment for depression: total charges and therapy duration*.

BACKGROUND: The economic costs of depression are significant, both the direct medical costs of care and the indirect costs of lost productivity. Empirical studies of antidepressant cost-effectiveness suggest that the use of selective serotonin reuptake inhibitors (SSRIs) may be no more costly than tricyclic antidepressants (TCAs), will improve tolerability, and is associated with longer therapy duration. However the success of depression care usually involves multiple factors, including source of care, type of care, and patient characteristics, in addition to drug choice.
