Depression decision support in primary care: a cluster randomized trial.

BACKGROUND: Intensive collaborative interventions improve depression outcomes, but the benefit of less intensive interventions is not clear. OBJECTIVE: To determine whether decision support improves outcomes for patients with depression. DESIGN: Clinician-level, cluster randomized, controlled trial. SETTING: 5 primary care clinics of 1 Veterans Affairs medical center. PARTICIPANTS: 41 primary care clinicians, and 375 patients with depression (Patient Health Questionnaire [PHQ-9] depression scores of 10 to 25 or Hopkins Symptom Checklist-20 [SCL-20] scores > or = 1.0). MEASUREMENTS: The primary outcome was change in depression score (SCL-20) at 6 and 12 months. Secondary outcomes were health-related quality-of-life (36-item Short Form for Veterans [SF-36V] score), patient satisfaction, antidepressant use, and health care utilization. INTERVENTION: Clinicians received depression education and were randomly assigned to depression decision support or usual care. The depression decision support team, which consisted of a psychiatrist and nurse, provided 1 early patient educational contact and depression monitoring with feedback to clinicians over 12 months. RESULTS: Although SCL-20 depression scores improved in both groups, the intervention had no effect compared with usual care. The difference in slopes comparing intervention and control over 12 months was 0.20 (95% CI, -0.37 to 0.78; P = 0.49), which was neither clinically nor statistically significant. Changes in SF-36V scores also did not differ between groups. At 12 months, intervention patients reported greater satisfaction (P = 0.002) and were more likely to have had at least 1 mental health specialty appointment (41.1% vs. 27.2%; P = 0.025), to have received any antidepressant (79.3% vs. 69.3%; P = 0.041), and to have received antidepressants for 90 days or more (76.2% vs. 61.6%; P = 0.008). LIMITATIONS: Usual care clinicians received depression education and had on-site mental health support, which may have mitigated intervention effectiveness. CONCLUSIONS: Decision support improved processes of care but not depression outcomes. More intensive care management or specialty treatment may be needed to improve depression outcomes.

"Not getting tanked": definitions of moderate drinking and their health implications.

BACKGROUND: People encounter large amounts of sometimes-inconsistent information about risks and benefits of alcohol consumption, and about what constitutes "low-risk" or "moderate" drinking. METHODS: We used 150 in-depth interviews linked to questionnaire data to learn how people define moderate drinking and to describe the relationships between definitions, attitudes, and beliefs about moderate drinking and individuals' drinking patterns. RESULTS: People adhere to definitions of moderate alcohol consumption that could put them, or others, at risk for short- or long-term negative consequences of drinking. Definitions that confused increased tolerance of alcohol with moderate drinking, and those that defined moderate drinking by the absence of short-term negative consequences or ability to maintain control over drinking, ignore long-term risks of heavy consumption. Individuals with risky attitudes were also more likely to report at-risk drinking practices. CONCLUSIONS: Americans have complex beliefs about benefits and risks of alcohol consumption, and public health officials have not succeeded in conveying strong or clear messages about what constitutes low-risk drinking or about dose-response effects. Different (but more consistent) approaches to public education may be needed to increase knowledge about drinking-related risks. The prevalence of diverse norm-based definitions suggests that alternative normative information could help people reassess their own consumption.

Advanced illness index: Predictive modeling to stratify elders using self-report data.

OBJECTIVES: Develop a prediction model to identify persons who have an increased risk of dying within the next 36 months, in order to focus additional resources and assessment in areas related to advanced care planning. DESIGN: Retrospective study with a 3-year observation period. SETTING: Integrated, not-for-profit managed care organization. PARTICIPANTS: Beneficiaries aged 65-105 responding to an annual survey (n = 4888). MEASUREMENTS: Survey instrument includes physical function, geriatric syndromes, health care utilization, special equipment use, self-care deficits, caregiving responsibilities, and general health problems. RESULTS: An 11-variable model changed the baseline chi2 from 315.71 (df = 1) to 742.511 (df = 11). The percent of subjects correctly classified was 74.3% and the negative predictive value was 92.2%. CONCLUSION: Advanced Illness Index (AII) model is stable. Characteristic variables used are not easily reversed: the 1997 cohort classified as at-risk consistently remained at risk or died in the subsequent years (1998, 92%; and 1999, 96%) and 92% of those not at-risk survived the next 36 months. Persons at high risk should at a minimum be made aware of the types of integrated home and community-based services available to them should it be needed. They also should be targeted for elicitation of treatment preferences, values, designation of health care proxy, planning, and advanced care directives.

Outcomes associated with dentists' risk assessment.

OBJECTIVE: To examine retrospectively the caries-related restorative experience of at-risk individuals who received fluoride-based preventive interventions to determine if the intervention resulted in fewer caries-related procedures. METHODS: Administrative data from two dental health plans were used to determine the relationship between caries risk assessment (CRA) scores, preventive treatment and caries-related treatment procedures. We identified 45 693 adults who were consecutively enrolled for at least 1 year before and 2.5 years after the CRA. Variables representing the number of teeth with any caries-related treatment procedure and receipt of preventive treatment were created. RESULTS: The outcome variable of interest was having at least one tooth with a caries-related procedure in the 2-year follow-up period. In plan A, the recommendation for home-use fluoride was not significantly related to caries-related treatment procedures in the follow-up period for individuals at low, moderate or high risk (P > 0.300). In plan B, application of in-office fluoride was associated with having at least one tooth with a caries-related treatment procedure in the follow-up period (P < 0.001). CONCLUSIONS: We found incomplete compliance with guidelines for recommendation or administration of preventive treatment for patients at elevated risk for caries. We were also unable to identify any significant reductions in caries-related procedures for individuals receiving a fluoride intervention, compared with those who did not, when stratified by risk level.

The cancer chemotherapy drug etoposide (VP-16) induces proinflammatory cytokine production and sickness behavior-like symptoms in a mouse model of cancer chemotherapy-related symptoms.

Cancer chemotherapy-related symptoms such as fatigue, malaise, loss of interest in social activities, difficulty concentrating, and changes in sleep patterns can lead to treatment delays, dose reductions, or termination and have a profound effect on the physical, psychosocial, and economic aspects of quality of life. Clinicians have long suspected that these symptoms are similar to those associated with "sickness behavior," which is triggered by the production of the inflammatory cytokines IL-1beta, TNF-alpha, and IL-6 by macrophages and other cells of the innate immune system in response to immune challenge. The p38 mitogen-activated protein kinase (p38 MAPK) plays a central role in the production of these cytokines and consequently the induction of sickness behavior. Several cancer chemotherapy drugs have been shown to activate p38 MAPK, but whether these drugs can also induce the production of inflammatory cytokines to cause sickness behavior is unknown. The aim of this study was to determine whether the cancer chemotherapy drug etoposide (VP-16), which is known to activate p38 MAPK, could induce inflammatory cytokine production by murine macrophages and sickness-like behaviors when injected into mice. VP-16 activated p38 MAPK and induced IL-6 production in murine macrophages in a p38 MAPK- dependent manner. VP-16 administration rapidly increased serum levels of IL-6 in healthy mice and induced sickness-like behaviors as evidenced by a decrease in food intake, body weight, hemoglobin level, and voluntary wheel-running activity. These findings support the idea that the induction of IL-1beta, TNF-alpha, and IL-6 by cancer chemotherapy drugs underlies the fatigue and associated symptoms experienced by people undergoing cancer chemotherapy.

Healthy aging demonstration project: nurse coaching for behavior change in older adults.

The Healthy Aging Project (HAP) tested nurse coaching as a method to support healthy behavior change in older adults. The sample included 111 individuals randomized to a nurse coaching group or usual-care control group. Participants in the intervention group chose the health behaviors they wanted to change and received coaching by nurses in a single in-person session followed by telephone calls or email contact for 6 months. Nurses were trained in motivational interviewing (MI). The intervention group had significantly less illness intrusiveness and health distress than the control group at 6 months, although it is not known whether these health outcomes resulted from behavior changes. This clinical demonstration project showed that nurse-delivered MI, primarily using the telephone and email, is a feasible method to discuss behavioral change with older adults. However, future clinical trials will be needed to evaluate the efficacy of nurse-delivered MI on actual behavioral changes in older adults.

Usefulness of a single item in a mail survey to identify persons with possible dementia: a new strategy for finding high-risk elders.

The objective of this study was to examine the characteristics of elderly persons who responded positively to a question about "severe memory problems" on a mailed health questionnaire yet were missed by the existing health risk algorithm to identify vulnerable elderly persons. A total of 324,471 respondents aged 65 and older completed a primary care health status questionnaire that gathered clinical information to quickly identify members with functional impairment, multiple chronic diseases, and higher medical care needs. The respondents were part of a large, integrated, not-for-profit managed care organization that implemented a model of care for elders using a uniform risk identification method across eight regions. Respondents with severe memory problems were compared to general respondents by morbidity, geriatric syndromes, functional impairments, service utilization, sensory impairments, sociodemographic characteristics, and activities of daily living. Of the respondents, 13,902 persons (4.3%) reported severe memory problems; the existing health risk algorithm missed 47.1% of these. When severe memory problems were included in the risk algorithm, identification increased from 11% to 13%, and risk prevalence by age groups ranged from 4.4% to 40.5%; one third had severe memory problems, a finding that was fairly consistent within age groups (28.4% to 36.5%). A question about severe memory problems should be incorporated into population risk-identification techniques. While false-negative rates are unknown, the false-positive rate of a self-report mail survey appears to be minimal. Persons reporting severe memory problems clearly have multiple comorbidities, higher prevalence of geriatric syndromes, and greater functional and sensory impairments.

Validation of a simple approach to caries risk assessment.

OBJECTIVE: This study examined the predictive validity of a simple subjective method promoted to dentists for assessing their patients' caries risk. METHODS: Data from two large group practices that have used guideline-assisted caries risk assessment (CRA) for several years were analyzed retrospectively to determine the receipt of caries-related treatment following a CRA. Patient age and receipt of caries preventive treatment subsequent to the CRA were control variables in logistic regressions to determine the likelihood of caries-related treatment for low, moderate, and high risk groups. RESULTS: Among 45,693 individuals in the two plans, those categorized as being at high caries risk were approximately four times as likely to receive any caries-related treatment as those categorized as being at low caries risk. Those categorized as at moderate risk were approximately twice as likely to receive any treatment. In addition, for those at elevated risk who required any treatment, the number of teeth requiring treatment was larger. CONCLUSION: The results of this study provide the first large-scale, generalizable evidence for the validity of dentists' subjective assessment of caries risk.

Mismatches in social support and psychosocial adjustment to breast cancer.

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences.

Gender differences in the relationships between multiple measures of alcohol consumption and physical and mental health.

BACKGROUND: Epidemiological research examining health consequences of alcohol consumption generally relies on average volume consumed, yet examinations of drinking patterns show different dimensions of use associated with different health outcomes. Gender differences in metabolism and body composition may lead to gender-specific consequences of drinking frequency, quantity consumed per occasion, average amount consumed, and drinking pattern. Inconsistent results suggest gender differences are not well understood. METHODS: Participants were 3069 male and 2600 female health maintenance organization survey respondents. Gender differences in relationships between alcohol consumption and health were examined using analyses of covariance adjusting for age alone and for age, ethnicity, marital status, body water index, and smoking. Past-year alcohol consumption (frequency, quantity per occasion, average drinks per month, and drinking pattern) and health measures (Short Form-36 general health, physical functioning, mental health subscales) were examined. RESULTS: Gender x drinking frequency and drinking quantity interactions were significant in age-adjusted and fully adjusted models of general health and physical functioning. Gender interactions for drinking pattern were significant in the age-adjusted model and marginally significant in the fully adjusted model. No gender x drinking measure interactions were found for mental health. Fully adjusted models attenuated but did not eliminate gender differences for health and magnified relationships for functioning, the latter after adjusting for body water. For both genders, light to moderate consumption and more frequent drinking were associated with better health and functioning; relationships were stronger among women than men. CONCLUSIONS: Gender x drinking measure interactions in health outcomes suggest analyses should include such interactions except, possibly, for mental health. Adjusting for potential confounders can attenuate (general health) or magnify (physical functioning) gender differences. Functional status appears a sensitive measure for evaluating gender differences in alcohol's health effects, adjusting for body water. Women's health may benefit proportionally more from moderate drinking than men's.

Out-of-hospital death: advance care planning, decedent symptoms, and caregiver burden.

OBJECTIVES: To examine the end-of-life experiences of elderly decedents dying out of the hospital and their family caregivers in a state in which the vast majority of Medicare deaths occur in community settings. DESIGN: Telephone survey of family caregivers 2 to 5 months after decedents' deaths. SETTING: Statewide (Oregon) random sample of death certificates. PARTICIPANTS: One thousand one hundred eighty-nine family caregivers of decedents aged 65 and older who died of natural deaths in community settings between 2000 and 2002. MEASUREMENTS: A 69-item telephone questionnaire with single-item indicators and embedded scales that indexed advance directives, use of life-sustaining treatments, hospice enrollment, decedent symptom experience and perceived distress, family financial hardship, out-of-pocket expenses, and caregiver strain. RESULTS: Most decedents had advance directives (78.3%) and were enrolled in hospice (62.4%). Although perceived decedent symptom distress was low overall, certain symptoms (e.g., pain, dyspnea, constipation) were distressing for approximately half of decedents experiencing them. Financial hardship, out-of-pocket expenses, and caregiver strain were frequently reported. American Indian race and younger age were associated with decedent symptom distress. Greater perceived decedent symptom distress, hospice enrollment, more caregiver involvement, and more financial burden were associated with greater caregiver strain. CONCLUSION: Despite high rates of advance directives and hospice enrollment, perceived symptom distress was high for a subset of decedents, and caregiver strain was common. As location of death increasingly shifts nationwide from hospital to community, unmet decedent and family needs require new clinical skills and healthcare policies.

Gender-based structural models of health care costs: alcohol use, physical health, mental health, and functioning.

BACKGROUND: Most models of health services use or costs include gender as a covariate, combining data for men and women in analyses. This strategy may obscure differences in underlying processes producing differential health care use by men and women, particularly in examinations of factors that affect health care use and differ by gender (e.g. alcohol consumption and depression). AIMS: To examine gender differences in the relationships between alcohol consumption, physical and mental health and functioning, and costs of health care. METHODS: The setting was Kaiser Permanente Northwest, a large non-profit group practice model HMO serving northwest Oregon and southwest Washington in the northwest United States. Primary (survey) and secondary (health plan records of service use; diagnoses from medical chart review) data were collected for random samples of health plan members in the period 1989-1993 (n = 5,669). Health plan administrative records of service use were used to estimate health care costs. Gender-specific latent structure models predicting health care costs were created using self-reported mental health, physical health, functioning, alcohol consumption, and prior-year health plan record-based diagnoses of depression and alcohol problems. RESULTS: Alcohol consumption and prior alcohol problems were directly related to health care costs, although in opposite directions, for both men and women. Alcohol consumption was negatively associated with costs, while prior alcohol problems predicted higher costs. Gender differences existed in the relationship between physical health and health care costs indirectly via drinking status. Prior depression had direct effects on increased health care costs, and this relationship was stronger for men than for women. The roles played by mental health symptoms were similar for men and women. Better mental health at the time of the survey was associated with reduced alcohol consumption or likelihood of consuming alcohol, but had no direct effects on later costs. Indirect effects of mental health were found via alcohol consumption. CONCLUSIONS: Gender plays an important role in the factors underlying total costs of health care, and gender differences in these relationships appear more common among those who consume alcohol. For both genders, alcohol use predicts lower health care costs in this light-to-moderate drinking population, although prior diagnoses of alcohol problems predict higher costs. The direct relationship between depression diagnosis and higher health care costs is stronger among men.

Patients with HIV infection and mental illness: a study of clinical identification.

We compared provider diagnosis of mental illness as noted in a chart audit to an indication of mental illness using the Revised Symptom Checklist (SCL-90R). We identified cases of correct diagnoses, over-diagnoses, and missed diagnoses of mental illness by examining mental functioning (using the SF-36). Providers over diagnosed mental illness in 23% of the cases and missed a diagnosis in 9% of the cases. The over-diagnosed group had significantly better mental functioning and the missed-diagnosis group did not have better mental functioning than those who the provider and SCL-90 agreed had mental illness. The SCL-90R had a higher correlation with mental functioning than did the providers' diagnoses, suggesting that such instruments may increase the correct detection of mental illness in the HIV population.

Structural models of gender, alcohol consumption, and health.

BACKGROUND: Gender differences exist in patterns of alcohol consumption and in the health and social effects of alcohol use, but little is known about gender differences in how alcohol use is affected by mental and physical health conditions. METHODS: We used structural equation modeling techniques to examine gender differences in the relationships among alcohol consumption, physical and mental health, functional status, and social and demographic characteristics. Data were obtained from a random sample of the adult membership of a health maintenance organization in the U.S. Pacific Northwest. Simultaneous models evaluated gender differences in predictors of drinking vs. nondrinking status and, among drinkers, amount of alcohol consumed. RESULTS: Physical health was twice as strong a predictor of drinker/nondrinker status among women compared with men, but among drinkers, there were no gender differences in predictors of amount of alcohol consumed. Mental health predicted drinking status and alcohol consumption among drinkers, but these relationships did not differ by gender. Overall, sociodemographic characteristics and physical health were stronger predictors of alcohol use among women than among men. CONCLUSIONS: Women may be more amenable than men to alcohol-related preventive messages that target physical health concerns. Treating mental health conditions may be an important method for reducing alcohol consumption.

Pessimism and optimism as early warning signs for compromised health for caregivers of patients with Parkinson's disease.

BACKGROUND: Although pessimism and optimism are associated with health-related outcomes, the long-term effects of pessimism and optimism in the caregiving process are understudied, and little is known about their role in health changes over time. OBJECTIVE: To determine whether pessimism and optimism can be used as early warning signs for negative changes in caregiver depressive symptoms and physical health over a 10-year period. METHODS: Multilevel modeling was used to examine longitudinal data from 311 spouse caregivers of individuals with Parkinson's disease, with data points at baseline, Year 2, and Year 10. Measures included the Life Orientation Test, the Center for Epidemiological Studies-Depression Scale, and the SF-36 Health Survey physical functioning scale. RESULTS: Caregiver pessimism early in the caregiver role was found to be a warning sign for poor current and future caregiver health. High baseline pessimism signaled high levels of baseline depressive symptoms and poor physical health, as well as a faster decline in health over the 10-year study. Optimism played a role in predicting baseline depressive symptoms, although the magnitude of its beneficial contribution was not as great as the deleterious effects of pessimism. CONCLUSIONS: Nurses and clinicians have a unique opportunity to detect and intervene with caregivers who show high levels of pessimism early in the caregiving trajectory.
