Fixed Dose Intervention Trial of New England Enhancing Survival in SMI Patients

By design, all subjects in the Intervention arm will start by being under treatment. During the course of follow-up, we expect that some will stay consistently on treatment, some will discontinue treatment (become non-adherent), while others will make transitions on and off treatment in various patterns. In contrast, by design, subjects in the Usual Treatment (control) arm do not start on treatment; however, some will initiate treatment as a result of usual clinical care, e.g., primary care physician initiation. At any point we will be comparing two binary outcomes (on or off treatment) and will use standard methods for comparing two proportions to test statistical significance and get confidence intervals for the difference in the percent on treatment in the two arms. Participants who are ineligible for randomization will be followed similarly to participants in the Usual Treatment Arm, in a third, non-randomized group, which will be excluded from the primary analysis.
