Cross-cultural aspects of depression management in primary care

Effectiveness of primary care interventions in conjointly treating comorbid chronic pain and depression: a systematic review and meta-analysis

BACKGROUND

Chronic pain and depression are highly comorbid, but the lack of consensus on the best treatment strategies puts patients at high risk of suboptimal care-coordination as well as health and social complications. Therefore, this study aims to quantitatively assesses how effective different primary care interventions have been in treating the comorbid state of chronic pain and depression. In particular, this study evaluates both short-term outcomes-based specifically on measures of chronic pain and depression during an intervention itself-and long-term outcomes or measures of pain and depression in the months after conclusion of the formal study intervention.

METHODS

This study is a systematic review and meta-analysis of randomised-controlled trials (RCTs) enrolling patients with concurrent chronic pain and depression. Intensity and severity of pain and depression symptoms were the primary outcomes. The main inclusion criteria were RCTs that: (i) enrolled patients diagnosed with depression and chronic pain, (ii) occurred in primary care settings, (iii) reported baseline and post-intervention outcomes for chronic pain and depression, (iv) lasted at least 8 weeks, and (v) used clinically validated outcome measures. Risk of bias was appraised with the Risk of Bias 2 tool, and GRADE guidelines were used to evaluate the quality of evidence.

RESULTS

Of 692 screened citations, 7 multicomponent primary care interventions tested across 891 patients were included. Meta-analyses revealed significant improvements in depression at post-intervention (SMD = 0.44, 95% CI [0.17, 0.71], P = 0.0014) and follow-up (SMD = 0.41, 95% CI [0.01, 0.81], P = 0.0448). Non-significant effects were observed for chronic pain at post-intervention (SMD = 0.27, 95% CI [-0.08, 0.61], P = 0.1287) and follow-up (SMD = 0.13, 95% CI [-0.3, 0.56], P = 0.5432).

CONCLUSIONS

Based on the results of the meta-analysis, primary care interventions largely yielded small to moderate positive effects for depressive symptoms and no significant effects on pain. In one study, stepped-care to be more effective in treatment of comorbid chronic pain and depression than other interventions both during the intervention and upon post-intervention follow-up. As such, depression appears more amenable to treatment than pain, but the number of published RCTs assessing both conditions is limited. More research is needed to further develop optimal treatment strategies.

The effectiveness of Culturally Sensitive Collaborative Treatment of depressed Chinese in family medicine clinics: A randomized controlled trial

OBJECTIVE

To investigate whether the Culturally Sensitive Collaborative Treatment (CSCT) would improve outcomes for patients with major depression who were managed in family medicine clinics in Taiwan.

METHOD

A single-blinded randomized trial was conducted in 26 family medicine clinics. Patients with major depressive disorder were consecutively randomized to either CSCT or treatment as usual (TAU). The primary outcome was the severity of depression. Secondary outcomes included treatment response, treatment remission, quality of life, and medication adherence. Outcomes were compared using hierarchical linear models (mixed-effects models) from baseline to 26-week follow-up assessments.

RESULTS

Of the 280 patients, 141 were randomized to TAU and 139 to CSCT. Hierarchical linear modeling revealed that the CSCT group displayed significantly greater improvement in depressive symptoms over the study period when compared to the TAU group (B=-2.60, P<0.001). The odds of achieving the response, remission, and medication adherence were significantly greater for the CSCT group compared to the TAU group (odds ratio=4.65, 4.12, and 2.06, respectively; all Ps<0.05). However, both groups did not differ significantly in quality of life.

CONCLUSION

CSCT is effective in improving treatment outcomes for major depression in family medicine clinics in Taiwan.

Multilevel context of depression in two American Indian tribes

OBJECTIVE

Depression is a major debilitating disease. For American Indians living in tribal reservations, who endure disproportionately high levels of stress and poverty often associated with depression, determining the patterns and correlates is key to appropriate clinical assessment and intervention development. Yet little attention has been given to the cultural context of correlates for depression, including the influence of family, cultural traditions or practices, or community conditions.

METHOD

We used data from a large representative psychiatric epidemiological study among American Indians in 2 reservation communities to estimate nested individual and multilevel models of past-year major depressive episode (MDE) accounting for family, cultural, and community conditions.

RESULTS

We found that models including culturally informed individual-level measures significantly improved the model fit over demographics alone. We found significant community-level variation in the probability of past-year MDE diagnosis in 1 tribe even after accounting for individual-level characteristics.

CONCLUSIONS

Accounting for culture, family, and community context will facilitate research, clinician assessment, and treatment of depression in diverse settings.

Integration of depression and primary care: barriers to adoption

OBJECTIVE

Despite the prevailing consensus as to its value, the adoption of integrated care models is not widespread. Thus, the objective of this article it to examine the barriers to the adoption of depression and primary care models in the United States.

METHODS

A literature search focused on peer-reviewed journal literature in Medline and PsycInfo. The search strategy focused on barriers to integrated mental health care services in primary care, and was based on previously existing searches. The search included: MeSH terms combined with targeted keywords; iterative citation searches in Scopus; searches for grey literature (literature not traditionally indexed by commercial publishers) in Google and organization websites, examination of reference lists, and discussions with researchers.

FINDINGS

Integration of depression care and primary care faces multiple barriers. Patients and families face numerous barriers, linked inextricably to create challenges not easily remedied by any one party, including the following: vulnerable populations with special needs, patient and family factors, medical and mental health comorbidities, provider supply and culture, financing and costs, and organizational issues.

CONCLUSIONS

An analysis of barriers impeding integration of depression and primary care presents information for future implementation of services.

Characterizing depression and comorbid medical conditions in African American women in a primary care setting

BACKGROUND

African American women are more likely to seek treatment for depression in primary care settings; however, few women receive guideline-concordant depression treatment in these settings. This investigation focused on the impact of depression on overall functioning in African American women in a primary care setting.

METHODS

Data was collected from a sample of 507 African American women in the waiting room of an urban primary care setting. The majority of women were well-educated, insured, and employed. The CESD-R was used to screen for depression, and participants completed the 36-Item Short-Form Survey to determine functional status.

RESULTS

Among the participants with depression, there was greater functional impairment for role-physical (z = -0.88, 95% CI = -1.13, -0.64) when compared to individuals with diabetes and hypertension. Individuals with depression also had greater role-emotional impairment (z = -1.12, 95% CI = -1.37, -0.87) than individuals with diabetes and hypertension. African American women with comorbid hypertension and depression had greater functional impairment in role-physical when compared to African American women with hypertension and no depression (t(124) = -4.22, p < 0.01).

CONCLUSION

African American women with depression are more likely to present with greater functional impairment in role function when compared to African American women with diabetes or hypertension. Because African American women often present to primary care settings for treatment of mental illness, primary care providers need to have a clear understanding of the population, as well as the most effective and appropriate interventions.
