Depression care management for Chinese Americans in primary care: a feasibility pilot study.

This study describes a culturally relevant intervention using a collaborative depression care model to integrate mental health and primary care services for depressed low income Chinese-Americans at a community health center. A total of 6,065 patients were screened for depression. Of the 341 who screened positive, 57 participated and were randomly assigned to receive either enhanced physician care with care management (32) or enhanced physician care only (25). All enrolled participants were assessed at baseline and 4 monthly follow-up visits for depression, physical and mental health functioning, and perceived stigma toward receiving depression care, to determine the impact, if any, of their mental health treatment. Both groups reported significant reduction of depressive symptoms and improved mental health functioning from baseline to follow-up assessments although there was no significant difference between the two groups. Although the study found no advantage to adding the care management component in the treatment of depression, screening and assertive treatment of immigrant Chinese Americans who tend to underutilize mental health services is important and consistent with the increased adoption of team based care models in patient centered medical homes. High refusal rates for enrollment in the study have implications for future study designs for this group.

Disability beliefs and help-seeking behavior of depressed Chinese-American patients in a primary care setting.

In this study the authors assessed the effects of disability beliefs, conceptualization and labeling of emotional disabilities, and perceived barriers on help-seeking behaviors among depressed Chinese Americans in a primary care setting. Forty-two Chinese Americans participated in semistructured interviews using established psychological measures and open-ended questions adapted from the Explanatory Model Interview Catalogue. The authors found that care utilization appears to be complicated by somatization of emotional problems, variations in causal attribution to depression, barriers to receiving mental health care, and the burden of comorbid physical conditions. Their findings highlight the importance of addressing these issues and educating patients about body-mind dialectic common to depression.

Religious participation as a predictor of mental health status and treatment outcomes in older persons.

OBJECTIVES: This study focuses on examining the relations of religious participation and affiliation to mental health status among older primary care patients, and to the use and clinical outcomes of mental health services. METHODS: A sample of older adults participating in a clinical study (PRISM-E) to treat their depression with or without co-morbid anxiety (n = 1610) were queried about their religious affiliation and the frequency of their participation in religious activities. The diagnoses of depressive and anxiety disorders were made based on the MINI-International Neuropsychiatric Interview. Severity of depressive disorders was assessed by emotional distress using the CES-D. RESULTS: Those attending religious activities on a weekly, monthly, or occasional basis were significantly less likely to have suicidal ideation (p < 0.02) and emotional distress (p < 0.0001) than those who never participated or participated on a less frequent basis. Frequency of religious participation was not associated with mental health service utilization (p = 0.16), but it was predictive of a lower CES-D score at the end of the study intervention (p < 0.001). CONCLUSIONS: Religious participation is positively associated with older adults' mental health status and treatment effects, but results regarding mental health service utilization were inconclusive.

Satisfaction with mental health services in older primary care patients.

OBJECTIVE: This study examines whether older adult primary care patients are satisfied with two intervention models designed to ameliorate their behavioral health problems. METHODS: A total of 1,052 primary care patients aged 65 and older with depression, anxiety, or at-risk drinking were randomly assigned to and participated in either integrated care (IC) or enhanced specialty referral (ESR) model and completed the Client Satisfaction Questionnaire (CSQ) administered at three-month follow-up assessment. RESULTS: Older adult patients' satisfaction with IC (mean: 3.4, standard deviation [SD]: 0.60) was significantly higher than that with ESR (mean: 3.2, SD: 0.78), but the absolute difference was modest. Regression results showed that patients who used the IC model, attended the treatment service twice or more, or showed clinical improvement were more likely to express greater satisfaction. Stigma toward mental illness was negatively associated with satisfaction with mental health services. CONCLUSIONS: Older adults are more likely to have greater satisfaction with mental health services integrated in primary care settings than through enhanced referrals to specialty mental health and substance abuse clinics.

Primary care clinicians evaluate integrated and referral models of behavioral health care for older adults: results from a multisite effectiveness trial (PRISM-e).

BACKGROUND: Recent studies have shown that integrated behavioral health services for older adults in primary care improves health outcomes. No study, however, has asked the opinions of clinicians whose patients actually experienced integrated rather than enhanced referral care for depression and other conditions. METHOD: The Primary Care Research in Substance Abuse and Mental Health for the Elderly (PRISM-E) study was a randomized trial comparing integrated behavioral health care with enhanced referral care in primary care settings across the United States. Primary care clinicians at each participating site were asked whether integrated or enhanced referral care was preferred across a variety of components of care. Managers also completed questionnaires related to the process of care at each site. RESULTS: Almost all primary care clinicians (n = 127) stated that integrated care led to better communication between primary care clinicians and mental health specialists (93%), less stigma for patients (93%), and better coordination of mental and physical care (92%). Fewer thought that integrated care led to better management of depression (64%), anxiety (76%), or alcohol problems (66%). At sites in which the clinicians were rated as participating in mental health care, integrated care was highly rated as improving communication between specialists in mental health and primary care. CONCLUSIONS: Among primary care clinicians who cared for patients that received integrated care or enhanced referral care, integrated care was preferred for many aspects of mental health care.

Relationship to insulin resistance of the adult treatment panel III diagnostic criteria for identification of the metabolic syndrome.

The Adult Treatment Panel III (ATP III) has published criteria for diagnosing the metabolic syndrome, a cluster of closely related abnormalities related to insulin resistance that increase cardiovascular disease risk. The present analysis was performed to evaluate the ability of these criteria to identify insulin-resistant individuals. The population consisted of 443 healthy volunteers, with measurements of BMI, blood pressure, fasting plasma glucose, triglycerides, HDL cholesterol concentrations, and steady-state plasma glucose (SSPG) concentration. Insulin resistance was defined as being in the top tertile of SSPG concentrations. Of the population, 20% satisfied ATP III criteria for the metabolic syndrome. Although insulin resistance and the presence of the metabolic syndrome were significantly associated (P < 0.001), the sensitivity and positive predictive value equaled 46% (69 of 149) and 76% (69 of 91), respectively. Being overweight, with high triglycerides, low HDL cholesterol, or elevated blood pressure, most often resulted in a diagnosis of the metabolic syndrome. Thus, the ATP III criteria do not provide a sensitive approach to identifying insulin-resistant individuals. The individual components vary both in terms of their utility in making a diagnosis of the metabolic syndrome and their relationship to insulin resistance, with the obesity and lipid criteria being most useful.

Immune systems biology: immunoprofiling of cells and molecules.

White blood cells and their secreted products are key elements of immune systems biology that are important indicators of patient health and disease. We have developed the SurroScan microvolume laser scanning cytometer to immunoprofile hundreds of variables, including cell populations, cell surface antigens, and intracellular molecules in antibody-based assays on small samples (about 1 mL) of whole blood, processed blood, or other fluids without cell purification or washing steps. The system enables high-throughput, robust and automated data capture and analysis. We demonstrate the utility of this immunoprofiling technology platform by surveying patient samples before and after glucocorticosteroid administration and show both the expected and novel response characteristics. This system complements recent advances in genomic and proteomic approaches to disease prediction and monitoring.

Use of metabolic markers to identify overweight individuals who are insulin resistant.

BACKGROUND: Insulin resistance is more common in overweight individuals and is associated with increased risk for type 2 diabetes mellitus and cardiovascular disease. Given the current epidemic of obesity and the fact that lifestyle interventions, such as weight loss and exercise, decrease insulin resistance, a relatively simple means to identify overweight individuals who are insulin resistant would be clinically useful. OBJECTIVE: To evaluate the ability of metabolic markers associated with insulin resistance and increased risk for cardiovascular disease to identify the subset of overweight individuals who are insulin resistant. DESIGN: Cross-sectional study. SETTING: General clinical research center. PATIENTS: 258 nondiabetic, overweight volunteers. MEASUREMENTS: Body mass index; fasting glucose, insulin, lipid and lipoprotein concentrations; and insulin-mediated glucose disposal as quantified by the steady-state plasma glucose concentration during the insulin suppression test. Overweight was defined as body mass index of 25 kg/m2 or greater, and insulin resistance was defined as being in the top tertile of steady-state plasma glucose concentrations. Receiver-operating characteristic curve analysis was used to identify the best markers of insulin resistance; optimal cut-points were identified and analyzed for predictive power. RESULTS: Plasma triglyceride concentration, ratio of triglyceride to high-density lipoprotein cholesterol concentrations, and insulin concentration were the most useful metabolic markers in identifying insulin-resistant individuals. The optimal cut-points were 1.47 mmol/L (130 mg/dL) for triglyceride, 1.8 in SI units (3.0 in traditional units) for the triglyceride-high-density lipoprotein cholesterol ratio, and 109 pmol/L for insulin. Respective sensitivity and specificity for these cut-points were 67%, 64%, and 57% and 71%, 68%, and 85%. Their ability to identify insulin-resistant individuals was similar to the ability of the criteria proposed by the Adult Treatment Panel III to diagnose the metabolic syndrome (sensitivity, 52%, and specificity, 85%). CONCLUSIONS: Three relatively simple metabolic markers can help identify overweight individuals who are sufficiently insulin resistant to be at increased risk for various adverse outcomes. In the absence of a standardized insulin assay, we suggest that the most practical approach to identify overweight individuals who are insulin resistant is to use the cut-points for either triglyceride concentration or the triglyceride-high-density lipoprotein cholesterol concentration ratio.

Suicidal and death ideation in older primary care patients with depression, anxiety, and at-risk alcohol use.

The authors identified correlates of active suicidal ideation and passive death ideation in older primary care patients with depression, anxiety, and at-risk alcohol use. Participants included 2,240 older primary care patients (age 65+), who were identified in three mutually exclusive groups on the basis of responses to the Paykel suicide questions: No Ideation, Death Ideation, and Suicidal Ideation. Chi-square, ANOVA, and polytomous logistic regression analyses were used to identify characteristics associated with suicidal ideation. The highest amount of suicidal ideation was associated with co-occurring major depression and anxiety disorder (18%), and the lowest proportion occurred in at-risk alcohol use (3%). Asians have the highest (57%) and African Americans have the lowest (27%) proportion of suicidal or death ideation. Fewer social supports and more severe symptoms were associated with greater overall ideation. Death ideation was associated with the greatest medical comorbidity and highest service utilization. Contrary to previous reports, authors failed to find that active suicidal ideation was associated with increased contacts with healthcare providers. Accordingly, targeted assessment and preventive services should be emphasized for geriatric outpatients with co-occurring depression and anxiety, social isolation, younger age, and Asian or Caucasian race.
