Pre-post Evaluation of Automated Reminders May Improve Detection and Management of Post-stroke Depression

Post-stroke depression (PSD) occurs in at least one-third of stroke survivors, is associated with worse functional outcomes and increased mortality, and is frequently underdiagnosed and undertreated.
To evaluate the effectiveness of an electronic medical record-based system intervention to improve the proportion of veterans screened and treated for PSD.
Quasi-experimental study comparing PSD screening and treatment among veterans receiving post-stroke outpatient care one year prior to the intervention (the control group) to those receiving outpatient care during the intervention period (the intervention group); contemporaneous data from non-study sites included to assess temporal trends in depression diagnosis and treatment.
Veterans hospitalized for ischemic stroke and/or receiving primary care (PC) or neurology outpatient follow-up within six months post-stroke at two (Veterans Affairs) VA Medical Centers.
We formed clinical improvement teams at both sites. Teams developed PSD screening and treatment reminders and designed tailored implementation strategies for reminder use in PC and neurology clinics.
Proportion screened for PSD within 6 months post-stroke; proportion screening positive for PSD who received an appropriate treatment action within 6 months post-stroke.
In unadjusted analyses, PSD screening was performed within 6 months for 85% of intervention (N = 278) vs. 50% of control (N = 374) patients (OR 6.2 , p < 0.001), and treatment action was received by 83% of intervention vs. 73% of control patients who screened positive (OR 1.8 p = 0.13). After adjusting for intervention, site and number of follow-up visits, intervention patients were more likely to be screened (OR 4.8, p < 0.001) and to receive a treatment action if screened positive (OR 2.45, p = 0.05). Analyses of temporal trends in non-study sites revealed no trend toward general increase in PSD detection or treatment.
Automated depression screening in primary and specialty care can improve detection and treatment of PSD.
