Depression care and treatment in a chronically ill Medicare population

Association of organizational culture and climate with variation in the clinical outcomes of collaborative care for maternal depression in community health centers

Background

Organizational factors may help explain variation in the effectiveness of evidence-based clinical innovations through implementation and sustainment. This study tested the relationship between organizational culture and climate and variation in clinical outcomes of the Collaborative Care Model (CoCM) for treatment of maternal depression implemented in community health centers.

Method

Organizational cultures and climates of 10 community health centers providing CoCM for depression among low-income women pregnant or parenting were assessed using the organizational social context (OSC) measure. Three-level hierarchical linear models tested whether variation in culture and climate predicted variation in improvement in depression symptoms from baseline to 6.5-month post-baseline for N = 468 women with care ±1 year of OSC assessment. Depression symptomology was measured using the Patient Health Questionnaire (PHQ-9).

Results

After controlling for patient characteristics, case mix, center size, and implementation support, patients served by centers with more proficient cultures improved significantly more from baseline to 6.5-month post-baseline than patients in centers with less proficient cultures (mean improvement = 5.08 vs. 0.14, respectively, p = .020), resulting in a large adjusted effect size of dadj = 0.78. A similar effect was observed for patients served by centers with more functional climates (mean improvement = 5.25 vs. 1.12, p < .044, dadj = 0.65). Growth models indicated that patients from all centers recovered on average after 4 months of care. However, those with more proficient cultures remained stabilized whereas patients served by centers with less proficient cultures deteriorated by 6.5-month post-baseline. A similar pattern was observed for functional climate.

Conclusions

Variation in clinical outcomes for women from historically underserved populations receiving Collaborative Care for maternal depression was associated with the organizational cultures and climates of community health centers. Implementation strategies targeting culture and climate may improve the implementation and effectiveness of integrated behavioral health care for depression.

German general practitioners' self-reported management of patients with chronic depression

BACKGROUND

Patients with chronic depression (persisting symptoms for ≥2 years) are a clinically relevant group with extensive (co)morbidity, high functional impairment and associated costs in primary care. The General Practitioner (GP) is the main health professional attending to these patients. The aim of this study was to examine the GPs' perception on managing patients with chronic depression.

METHODS

We performed an explorative cross-sectional study with a systematic sample of GPs in central Germany. Source of data was a written questionnaire (46 items). Descriptive analysis was carried out.

RESULTS

Two hundred twenty (out of 1000; 22%) GPs participated. 93% of the GPs distinguish between care for patients with chronic depression and acute depressive episode. 92% would recommend psychotherapeutic co-treatment to the chronically depressed patient. 52% of GPs would favour a general restraint on antidepressants (ADs) in older chronically depressed patients (≥ 75 years) whereas 40% suggest long-term pharmacotherapy. If severe physical comorbidity is present GPs would be restrictive in prescribing ADs (65%) or would urgently refer to specialist psychiatric services (40%). In case of a comorbid anxiety disorder 66% of the GPs would suggest a combined psycho- und pharmacotherapy. If a substance use disorder coexists 84% would prefer urgent referrals to specialist services.

CONCLUSIONS

Participating GPs report awareness towards chronic depression in their patients. Physical and mental comorbidity seem to play an important role in GPs' treatment decisions.

When depression is diagnosed, older adults are as likely as younger adults to be prescribed pharmacotherapy and psychotherapy

OBJECTIVE

This study examined age group differences in the rates of depression diagnosis and treatment using a national probability sample.

METHODS

Using data from the 2012 National Ambulatory Medical Care Survey (n=62,723 visits by patients aged 18+ years), we used bivariate and multivariable binary logistic regression analyses to test age group differences in antidepressant medication (ADM) and psychotherapy prescribed/ordered or provided at visits during which depression was diagnosed.

RESULTS

Visits by older adults were less likely to result in a depression diagnosis than visits by younger individuals: 2.46% and 1.80% in the 65-74 and 75+ age groups, compared to 4.06%, 4.24% and 4.12% in the 18-29, 30-49 and 50-64 age groups, respectively. Of all visits involving diagnosed depression, 65.88% included prescribing/ordering or providing ADM and 19.01% included psychotherapy ordering or providing, without significant age group difference. Prescribing/ordering or providing ADM occurs frequently during visits to physicians regardless of specialty, while psychotherapy was ordered or provided mostly during visits to psychiatrists.

CONCLUSIONS

During ambulatory care visits in which depression was diagnosed, older adults were as likely as younger adults to be prescribed/provided treatment; however, in more than 30% of visits by depressed older adults neither ADM nor psychotherapy was prescribed.

Identification and treatment of depression of older adults in primary care: findings from the São Paulo Ageing and Health Study

BACKGROUND

Depression, diabetes and hypertension are major contributors to the global burden of disease; however, the majority of research on depression and co-morbid conditions originates in high-income countries.

OBJECTIVE

This study examines the depression identification rate and compares treatment rates of depression with those of diabetes and hypertension among elderly individuals served in primary care through the Family Health Program (FHP) in São Paulo, Brazil.

METHOD

A total of 1558 São Paulo Ageing and Health Study participants (low-income adults ≥65 years old living in São Paulo) registered in the FHP were included for analysis. Chart review was performed for participants with an International Classification of Diseases, 10th edition (ICD-10) depression diagnosis (from survey interview) to verify if depression was recorded for these individuals. Depression, diabetes and hypertension treatment were assessed based on clinical assessments and medication checks.

RESULTS

Seventy-three participants (4.8%) had ICD-10 depression, 344 (23.2%) had confirmed diabetes and 1207 (79.3%) had confirmed hypertension. The proportion of those identified with depression by medical chart review (n = 63 for individuals whose chart could be found) was 4.8% (n = 3). Nine individuals (12.3%) with ICD-10 depression were treated. Rates of diabetes and hypertension treatment were 72.4% and 77.4%, respectively.

CONCLUSION

Levels of treatment of depression in older adults receiving care in the FHP is very low compared to treatment rates of diabetes and hypertension. Collaborative care effectiveness trials for the treatment of depression in the FHP are needed to improve the quality of depression care for this population.

Pharmacologic management of bipolar disorder in a Medicare Advantage population

OBJECTIVE

The purpose of this study was to examine patterns of pharmacotherapy for beneficiaries in a high-risk Medicare Advantage program who were diagnosed with bipolar disorder.

METHODS

This was a cross-sectional study of 2338 Medicare Advantage beneficiaries diagnosed with bipolar disorder. Pharmacotherapy treatment was assessed via receipt of (1) a mood stabilizer or antipsychotic or both (i.e., guideline concordant bipolar care) and (2) unopposed antidepressant (i.e., without prescription of a mood stabilizer or an antipsychotic). Logistic regression was used to examine correlates of bipolar disorder care.

RESULTS

Among those younger than 65 years of age (n = 1395), 54% received guideline concordant therapy and 29% received unopposed antidepressant therapy. Among those 65 years and older (n = 943), 40% received guideline concordant therapy and 33% received unopposed antidepressant therapy.

CONCLUSION

Overall, about half of beneficiaries in this Medicare Advantage plan received guideline concordant pharmacotherapy for bipolar disorder, while approximately one-third received an unopposed antidepressant prescription. Antipsychotic medications accounted for most of the monotherapy observed. This study identifies opportunities for further improvements in the pharmacotherapy of bipolar disorder in high-risk Medicare patients.
