Abstract
Background: Despite an unparalleled global refugee crisis, there are almost no studies in primary care addressing real-world conditions and longer courses of treatment that are typical when resettled refugees present to their physician with critical psychosocial needs and complex symptoms. Our aim was to study the effects of a year of psychotherapy and case management in a primary care setting on common symptoms and functioning for Karen refugees (a newly arrived population in the study location) with depression.
Methods: A pragmatic parallel-group randomized control trial was conducted at two primary care clinics with large resettled Karen refugee patient populations, with simple random allocation to one year of either: (1) intensive psychotherapy and case management (IPCM), or (2) care-as-usual (CAU). Eligibility criteria included Major Depression diagnosis, Karen refugee, ages 18-65. IPCM (n=112) received a year of psychotherapy and case management coordinated onsite between the case manager, psychotherapist, and primary care providers; CAU (n=102) received care-as-usual from their primary care clinic, including behavioral health referrals and/or brief onsite interventions. Blinded assessors collected outcomes of mean changes in depression, anxiety, PTSD, pain, and social functioning at baseline, 3, 6 and 12 months. Measures included HSCL-25 (depression and anxiety), PDS (PTSD), pain (range of 0-4), and social functioning scales (range of 0-4). Data were analyzed with the intention-to-treat principle.
Results: Among 214 randomized participants, 193 completed a baseline and follow up assessment (90.2%). IPCM patients showed significant improvements in depression, PTSD, anxiety, and pain symptoms and in social functioning at 3, 6, and 12 months, with magnitude of improvement increasing over time. CAU patients did not show significant improvements. The largest mean differences observed between groups were in depression (difference, 5.5, 95% CI, 3.9 to 7.1, P<.001) and basic needs/safety (difference, 5.4, 95% CI, 3.8 to 7.0, P<.001).
Conclusions: Adult Karen refugees with depression benefited from intensive psychotherapy and case management coordinated and delivered under usual conditions in primary care. Intervention effects strengthened at each interval, suggesting robust recovery is possible.
