Effect of Long-term Vitamin D3 Supplementation vs Placebo on Risk of Depression or Clinically Relevant Depressive Symptoms and on Change in Mood Scores: A Randomized Clinical Trial

IMPORTANCE

Low levels of 25-hydroxyvitamin D have been associated with higher risk for depression later in life, but there have been few long-term, high-dose large-scale trials.

OBJECTIVE

To test the effects of vitamin D3 supplementation on late-life depression risk and mood scores.

DESIGN, SETTING, AND PARTICIPANTS

There were 18 353 men and women aged 50 years or older in the VITAL-DEP (Vitamin D and Omega-3 Trial-Depression Endpoint Prevention) ancillary study to VITAL, a randomized clinical trial of cardiovascular disease and cancer prevention among 25 871 adults in the US. There were 16 657 at risk for incident depression (ie, no depression history) and 1696 at risk for recurrent depression (ie, depression history but no treatment for depression within the past 2 years). Randomization occurred from November 2011 through March 2014; randomized treatment ended on December 31, 2017, and this was the final date of follow-up.

INTERVENTION

Randomized assignment in a 2 × 2 factorial design to vitamin D3 (2000 IU/d of cholecalciferol) and fish oil or placebo; 9181 were randomized to vitamin D3 and 9172 were randomized to matching placebo.

MAIN OUTCOMES AND MEASURES

The primary outcomes were the risk of depression or clinically relevant depressive symptoms (total of incident and recurrent cases) and the mean difference in mood scores (8-item Patient Health Questionnaire depression scale [PHQ-8]; score range, 0 points [least symptoms] to 24 points [most symptoms]; the minimal clinically important difference for change in scores was 0.5 points).

RESULTS

Among the 18 353 randomized participants (mean age, 67.5 [SD, 7.1] years; 49.2% women), the median treatment duration was 5.3 years and 90.5% completed the trial (93.5% among those alive at the end of the trial). Risk of depression or clinically relevant depressive symptoms was not significantly different between the vitamin D3 group (609 depression or clinically relevant depressive symptom events; 12.9/1000 person-years) and the placebo group (625 depression or clinically relevant depressive symptom events; 13.3/1000 person-years) (hazard ratio, 0.97 [95% CI, 0.87 to 1.09]; P = .62); there were no significant differences between groups in depression incidence or recurrence. No significant differences were observed between treatment groups for change in mood scores over time; mean change in PHQ-8 score was not significantly different from zero (mean difference for change in mood scores, 0.01 points [95% CI, -0.04 to 0.05 points]).

CONCLUSIONS AND RELEVANCE

Among adults aged 50 years or older without clinically relevant depressive symptoms at baseline, treatment with vitamin D3 compared with placebo did not result in a statistically significant difference in the incidence and recurrence of depression or clinically relevant depressive symptoms or for change in mood scores over a median follow-up of 5.3 years. These findings do not support the use of vitamin D3 in adults to prevent depression.

Considerations and Current Trends in the Management of the Geriatric Patient on a Consultation-Liaison Service

PURPOSE OF REVIEW

To provide consultation-liaison psychiatrists with an updated resource that can assist in the treatment and management of geriatric patients.

RECENT FINDINGS

The current available literature has not shown any differences in efficacy between haloperidol and second-generation antipsychotics in patients with delirium. When considering relative advantages of forms of antipsychotic administration, there is no support for a superior safety profile of oral compared to intramuscular or intravenous administration. A recent meta-analysis of four randomized controlled trials concluded that when melatonin was administered to older age patients on medical wards, it significantly prevented the incidence of delirium when compared with the control group. While suvorexant administered nightly to elderly patients in acute care settings may lower the incidence of delirium, larger studies are needed to confirm this finding. Despite the black box warning of increased mortality risk in older patients with dementia, antipsychotics may be used with caution by the consultation-liaison (CL) psychiatrist to treat the neuropsychologic symptoms of dementia including hallucinations and psychosis in the hospital setting. While antidepressant studies have focused primarily on citalopram and escitalopram in the treatment of agitation in the setting of dementia, these two medications have not been adequately compared directly to other SSRIs for this condition. It is therefore not clear whether citalopram and escitalopram are more efficacious in treating agitation in the setting of dementia when compared to other SSRIs. While the evidence supporting trazodone's use is limited, it is generally well tolerated and is an option as a PRN for irritability and agitation in patients with Alzheimer's and mixed dementia. While there is some evidence to support the use of acetylcholinesterase inhibitors for treating cognitive impairments and hallucinations in Lewy body dementia, the usefulness of these agents in other forms of dementia is not well studied, and those studies did not show any benefit in the management of acute agitation. It is important to note that memantine can cause or exacerbate agitation and may be the cause of behavioral dysregulation. There is no evidence to support the routine use of benzodiazepines for behavioral improvement in patients with dementia. Escitalopram and citalopram do have a unique pharmacokinetic properties in the sense that they have been found to have 50-56% plasma protein binding, compared to sertraline, fluoxetine, and paroxetine (95% or more). Pooled analyses suggest that antidepressants are more effective than placebo in reducing the symptoms of post-stroke depression. SSRIs are considered first-line antidepressants in stroke patients, who are often elderly with underlying cardiovascular problems. Although treatment with SSRIs is recommended for post-stroke depression, there are no studies providing conclusive data on the superiority of a specific drug. Older age is associated with a better outcome from ECT, with remission rates of approximately 73% to 90% in patients over 65 years. ECT is the treatment of choice for patients with psychotic depression, and elderly patients with psychotic depression have been shown to have a higher remission rate and faster time to response than depressed patients without psychotic symptoms. With the average life expectancy increase, it is projected that 19 million people will reach the age of 85 or higher, an increase from 5.5 million in 2010. With an increasing older population, psychiatric consultation in the management of geriatric patients is becoming more necessary. Psychiatrists must be aware of the unique considerations in elderly patients. In this article, we provide evidence-based guidance to the CL psychiatrist on major issues relating to the older age patient, highlighting recent trends in treatment. First, we provide background on the evaluation of the medically hospitalized geriatric patient. As rates of medical and psychiatric illnesses increase with advancing age, elderly patients are more likely to be taking a higher number of medications as compared to younger patients, and physicians must pay special attention to polypharmacy, including side effects and drug interactions in this group. Next, we focus on the diagnosis, management, and unique needs of the geriatric patient presenting with common clinical syndromes of delirium, dementia, and depression. Delirium and dementia are among the most common causes of cognitive impairment in clinical settings yet are often either unrecognized or misdiagnosed as they may have similar signs and symptoms. In addition, depression is prevalent in older adults, especially in those with comorbid medical illness. Depression can be fatal as the rates of suicide are higher in later life than in any other age group. Consultation can improve the management of elderly patients and prevent unnecessary nursing home placement.

Sociodemographic inequalities in the management of depression in adults aged 55 and over: an analysis of English primary care data

BACKGROUND

We do not know how primary care treatment of depression varies by age across both psychotropic medication and psychological therapies.

METHODS

Cohort study including 19 710 people aged 55+ with GP recorded depression diagnoses and 26 276 people with recorded depression symptoms during the period 2009-2013, from 373 General Practices in The Health Improvement Network (THIN) database in England. Main outcomes were initiation of treatment with anti-depressants, anxiolytics, hypnotics, anti-psychotic drugs, referrals to psychological therapies within 6 months of onset.

RESULTS

Treatment rates with antidepressants are high for those recorded with new depression diagnoses (87.1%) or symptoms of depression (58.7%). Treatment in those with depression diagnoses varies little by age. In those with depressive symptoms there was a J-shaped pattern with reduced antidepressant treatment in those in their 60s and 70s followed by increased treatment in the oldest age groups (85+ years), compared with those aged 55-59 years. Other psychotropic drug prescribing (hypnotics/anxiolytics, antipsychotics) all increase with increasing age. Recorded referrals for psychological therapies were low, and decreased steadily with increasing age, such that women aged 75-79 years with depression diagnoses had around six times lower odds of referral (OR 0.17, 95% CI 0.1-0.29) than those aged 55-59 years, and men aged 80-84 years had around seven times lower (OR 0.14, 95% CI 0.05-0.36).

CONCLUSIONS

The oldest age groups with new depression diagnoses and symptoms have fewer recorded referrals to psychological therapies, and higher psychotropic drug treatment rates in primary care. This suggests potential inequalities in access to psychological therapies.

Determinants of follow-up care associated with incident antidepressant use in older adults

Objectives

To determine the proportion of older adults receiving guideline concordant antidepressant therapy and to determine patient, prescriber and organizational factors associated with adequate antidepressant therapy.

Methods

The study included secondary analyses of data collected in the Étude sur la Santé des Aînés (ESA) Services study on older adults recruited while consulting in primary care clinics in one of the largest health regions of the province of Québec. Antidepressant users (n = 349) were identified from information collected from the Régie de l’Assurance Maladie du Québec (RAMQ) pharmaceutical database which holds information on all drugs dispensed to all residents covered under the public drug plan. Adequacy of antidepressant treatment was measured using three criteria: adequacy of daily dose; length of prescription (≥455 days); and ≥3 visits to the antidepressant-prescribing physician in the first 3 months after initiation of therapy. Multivariate logistic regression analyses were used to study antidepressant treatment adequacy as a function of individual, provider and healthcare system factors.

Results

Among the antidepressant users, 44% received an adequate antidepressant treatment filling all three criteria. None of the factors studied were associated with the probability of receiving adequate treatment filling all three criteria. Psychological distress was associated with having an adequate number of visits in the 3 months following initiation. Males and those living in a metropolitan and urban area were less likely to receive an adequate dose.

Conclusions

Future research should consider factors associated with perceived effectiveness and patient treatment preferences that may explain receipt of adequate antidepressant treatment in older adults.

The 12-month prevalence of depression and health care utilization in the general population of Latvia

BACKGROUND

This cross-sectional study aims to assess the 12-month prevalence of major and minor depression in the Latvian population, and to evaluate associated health care utilization.

METHODS

Trained interviewers conducted face-to-face interviews with a multistage stratified probability sample of the Latvian general population, ages 15-64 (n=3003). Participants were interviewed using the depression module of the Mini International Neuropsychiatric Interview. Self-reported health care utilization and somatic illness were also assessed. Multinomial logistic regressions were applied.

RESULTS

The 12-month prevalence of major depression was 7.9% (95%CI 7.0-8.9), while for minor depression it was 7.7% (95%CI 6.8-8.7). We did not find a substantial difference in the relative risk ratio (RRR 1.7 for female) for having major depression by gender. RRR of having major depression was higher for those who had used healthcare services six or more times (RRR 2.0), those who had three or more somatic disorders during the past 12 months (RRR 2.3), those who perceived their health status as being below average (RRR 8.3), and those who were occasional smokers (RRR 3.0). RRR of having minor depression was increased for those who had at least three somatic disorders (RRR 2.3), those who received disability pension (RRR 1.9), and those who perceived their health status to be below average (RRR 3.0).

LIMITATIONS

The study was cross-sectional. Other psychiatric comorbidity was not assessed.

CONCLUSIONS

This is the first population based study reporting the 12-month prevalence of depression in Latvia. Certain factors associated with depression have been found.

The role of vitamin D in the prevention of late-life depression

BACKGROUND

In this article, we review current evidence regarding potential benefits of vitamin D for improving mood and reducing depression risk in older adults. We summarize gaps in knowledge and describe future efforts that may clarify the role of vitamin D in late-life depression prevention.

METHODS

MEDLINE and PsychINFO databases were searched for all articles on vitamin D and mood that had been published up to and including May 2015. Observational studies and randomized trials with 50 or more participants were included. We excluded studies that involved only younger adults and/or exclusively involved persons with current depression.

RESULTS

Twenty observational (cross-sectional and prospective) studies and 10 randomized trials (nine were randomized placebo-controlled trials [RCTs]; one was a randomized blinded comparison trial) were reviewed. Inverse associations of vitamin D blood level or vitamin D intake with depression were found in 13 observational studies; three identified prospective relations. Results from all but one of the RCTs showed no statistically significant differences in depression outcomes between vitamin D and placebo groups.

LIMITATIONS

Observational studies were mostly cross-sectional and frequently lacked adequate control of confounding. RCTs often featured low treatment doses, suboptimal post-intervention changes in biochemical levels of vitamin D, and/or short trial durations.

CONCLUSION

Vitamin D level-mood associations were observed in most, but not all, observational studies; results indicated that vitamin D deficiency may be a risk factor for late-life depression. However, additional data from well-designed RCTs are required to determine the impact of vitamin D in late-life depression prevention.

Loneliness and depressive symptoms among older adults: The moderating role of subjective life expectancy

Loneliness and depressive symptoms are closely related, and both are indicators of reduced physical and mental well-being in old age. In recent years, the subjective perception of how long an individual expects to live (subjective life expectancy) has gained importance as a significant predictor of future psychological functioning, as well as of physical health. The current study examined whether subjective life expectancy moderates the connection between loneliness and depressive symptoms in a representative sample of older adults. Data was collected from the Israeli component of the fifth wave of the Survey of Health, Ageing and Retirement in Europe (SHARE-Israel). Participants (n=2210; mean age=70.35) completed measures of loneliness, depressive symptoms, and life expectancy target age. A hierarchical regression analysis predicting depressive symptoms yielded a significant interaction of loneliness and subjective life expectancy. Further analyses demonstrated that low subjective life expectancy mitigated the loneliness-depressive symptoms connection. Findings are discussed in light of the potential burden of higher subjective life expectancy for lonesome older adults, and practical implications are suggested.

Examining functional and social determinants of depression in community-dwelling older adults: implications for practice

Coping with declining health, physical illnesses and complex medical regimens, which are all too common among many older adults, requires significant lifestyle changes and causes increasing self-management demands. Depression occurs in community-dwelling older adults as both demands and losses increase, but this problem is drastically underestimated and under-recognized. Depressive symptoms are often attributed to physical illnesses and thus overlooked, resulting in lack of appropriate treatment and diminished quality of life. The purpose of this study is to assess prevalence of depressive symptoms in community-dwelling older adults with high levels of co-morbidity and to identify correlates of depression. In this sample of 533 homebound older adults screened (76.1% female, 71.8% white, mean age 78.5 years) who were screened using the Geriatric Depression Scale (SF), 35.9% scored greater than 5. Decreased satisfaction with family support (p << 0.001) and functional status (p ≤ 0.001) and increased loneliness (p < 0.001) were significant independent predictors of depression status in this sample; thus, these factors should be considered when planning care.

Elderly care recipients' perceptions of treatment helpfulness for depression and the relationship with help-seeking

Objective

This study aims to examine perceptions of the helpfulness of treatments/interventions for depression held by elderly care recipients, to examine whether these beliefs are related to help-seeking and whether the experience of depression affects beliefs about treatment seeking, and to identify the characteristics of help-seekers.

Method

One hundred eighteen aged care recipients were surveyed on their beliefs about the helpfulness of a variety of treatments/interventions for depression, on their actual help-seeking behaviors, and on their experience of depression (current and past).

Results

From the sample, 32.4% of the participants screened positive for depression on the Geriatric Depression Scale, and of these, 24.2% reported receiving treatment. Respondents believed the most helpful treatments for depression were increasing physical activity, counseling, and antidepressant medication. Help-seeking from both professional and informal sources appeared to be related to belief in the helpfulness of counseling and antidepressants; in addition, help-seeking from informal sources was also related to belief in the helpfulness of sleeping tablets and reading self-help books. In univariate analyses, lower levels of cognitive impairment and being in the two lower age tertiles predicted a greater likelihood of help-seeking from professional sources, and female sex and being in the lower two age tertiles predicted greater likelihood of help-seeking from informal sources. In multivariate analyses, only lower levels of cognitive impairment remained a significant predictor of help-seeking from professional sources, whereas both lower age and female sex continued to predict a greater likelihood of help-seeking from informal sources.

Conclusion

Beliefs in the helpfulness of certain treatments were related to the use of both professional and informal sources of help, indicating the possibility that campaigns or educational programs aimed at changing beliefs about treatments may be useful in older adults.

An interprofessional nurse-led mental health promotion intervention for older home care clients with depressive symptoms

Background

Depressive symptoms in older home care clients are common but poorly recognized and treated, resulting in adverse health outcomes, premature institutionalization, and costly use of health services. The objectives of this study were to examine the feasibility and acceptability of a new six-month interprofessional (IP) nurse-led mental health promotion intervention, and to explore its effects on reducing depressive symptoms in older home care clients (≥ 70 years) using personal support services.

Methods

A prospective one-group pre-test/post-test study design was used. The intervention was a six-month evidence-based depression care management strategy led by a registered nurse that used an IP approach. Of 142 eligible consenting participants, 98 (69%) completed the six-month and 87 (61%) completed the one-year follow-up. Outcomes included depressive symptoms, anxiety, health-related quality of life (HRQoL), and the costs of use of all types of health services at baseline and six-month and one-year follow-up. An interpretive descriptive design was used to explore clients’, nurses’, and personal support workers’ perceptions about the intervention’s appropriateness, benefits, and barriers and facilitators to implementation.

Results

Of the 142 participants, 56% had clinically significant depressive symptoms, with 38% having moderate to severe symptoms. The intervention was feasible and acceptable to older home care clients with depressive symptoms. It was effective in reducing depressive symptoms and improving HRQoL at six-month follow-up, with small additional improvements six months after the intervention. The intervention also reduced anxiety at one year follow-up. Significant reductions were observed in the use of hospitalization, ambulance services, and emergency room visits over the study period.

Conclusions

Our findings provide initial evidence for the feasibility, acceptability, and sustained effects of the nurse-led mental health promotion intervention in improving client outcomes, reducing use of expensive health services, and improving clinical practice behaviours of home care providers. Future research should evaluate its efficacy using a randomized clinical trial design, in different settings, with an adequate sample of older home care recipients with depressive symptoms.

Improving engagement in mental health treatment for home meal recipients with depression

Background

Staff who provide support services to older adults are in a unique position to detect depression and offer a referral for mental health treatment. Yet integrating mental health screening and recommendations into aging services requires staff learn new skills to integrate mental health and overcome client barriers to accepting mental health referrals. This paper describes client rates of depression and a novel engagement intervention (Open Door) for homebound older adults who are eligible for home delivered meals and screened for depression by in-home aging service programs.

Methods

Homebound older adults receiving meal service who endorsed depressive symptoms were interviewed to assess depression severity and rates of suicidal ideation. Open Door is a brief psychosocial intervention to improve engagement in mental health treatment by collaboratively addressing the individual level barriers to care. The intervention targets stigma, misconceptions about depression, and fears about treatment, and is designed to fit within the roles and responsibilities of aging service staff.

Results

Among 137 meal recipients who had symptoms when screened for depression as part of routine home meal service assessments, half (51%) had Major Depressive Disorder and 13% met criteria for minor depression on the SCID. Suicidal ideation was reported by 29% of the sample, with the highest rates of suicidal ideation (47%) among the subgroup of individuals with Major Depressive Disorder.

Conclusion

Individuals who endorse depressive symptoms during screening are likely to have clinically significant depression and need mental health treatment. The Open Door intervention offers a strategy to overcome barriers to mental health treatment engagement and to improve the odds of quality care for depression.

Racial differences in adherence to antidepressant treatment in later life

OBJECTIVE

Although antidepressants are an effective treatment for later-life depression, older patients often choose not to initiate or to discontinue medication treatment prematurely. Although racial differences in depression treatment preferences have been reported, little is known about racial differences in antidepressant medication adherence among older patients.

DESIGN

Prospective, observational study comparing antidepressant adherence for older African American and white primary care patients.

PARTICIPANTS

A total of 188 subjects age 60 and older, diagnosed with clinically significant depression with a new recommendation for antidepressant treatment by their primary care physician.

MEASUREMENT

Study participants were assessed at study entry and at the 4-month follow-up (encompassing the acute treatment phase). Depression medication adherence was based on a well-validated self-report measure.

RESULTS

At the 4-month follow-up, 61.2% of subjects reported that they were adherent to their antidepressant medication. In unadjusted and two of the three adjusted analyses, African American subjects (n = 82) had significantly lower rates of 4-month antidepressant adherence than white subjects (n = 106). African American women had the lowest adherence rates (44.4%) followed by African American men (56.8%), white men (65.3%), and white women (73.7%). In logistic regression models controlling for demographic, illness, and functional status variables, significant differences persisted between African American women and white women in reported 4-month antidepressant adherence (OR: 3.58, 95% CI: 1.27-10.07, Wald χ(2) = 2.42, df = 1, p <0.02).

CONCLUSIONS

The results demonstrate racial and gender differences in antidepressant adherence in older adults. Depression treatment interventions for older adults should take into account the potential impact of race and gender on adherence to prescribed medications.

The effects of care management on depression treatment in a psychiatric clinic: a randomized controlled trial

OBJECTIVE

This study aims to examine whether care management has an effect on adherence to depression treatment in a psychiatric clinic in Korea.

METHODS

Fifty-seven patients with depression aged 60 years or over participated in the study. They were all low-income patients screened in the community and treated in a psychiatric clinic. The study design was a double-blind randomized controlled trial. The patients were randomly assigned to intervention (n = 29) or usual care (n = 28) groups. Intervention patients received depression care management for 6 months. Primary endpoint was an increase in remission rate as assessed using the 17-item Hamilton Depression Rating Scale score at 6 months. Secondary endpoints included improvement in treatment adherence, improvement in health-related quality of life, and a reduction in feelings of hopelessness.

RESULTS

Patients in the care management intervention group showed a higher remission rate than those in the usual care group (55% vs. 29%, p = 0.0421). Intervention patients were significantly more likely to adhere to the treatment (59% vs. 18%, p = 0.0016). The hopelessness score at the 6-month assessment was significantly lower in the intervention group than the usual care group (23.5 vs. 25.7, p = 0.0443). However, there was not a significant group difference in the quality of life.

CONCLUSIONS

We found that care management not only contributed to reducing depressive symptoms in geriatric patients suffering from depression but also increased the treatment adherence rate, which in turn increased the remission rate. Care management intervention is both feasible and effective in psychiatric clinics in Korea.

Personalizing behavioral interventions: the case of late-life depression

This article reviews the potential utility of behavioral interventions in personalized depression treatment. The paper begins with a definition of personalized treatment, moves to current thinking regarding the various causes of depression, and proposes how those causes can be used to inform the selection of behavioral interventions. Two examples from the late-life depression field will illustrate how a team of researchers at Cornell University (NY, USA) and University of California, San Francisco (CA, USA) created a research partnership to select and study behavioral interventions for older adults with risk factors associated with poor response to selective serotonin reuptake inhibitor medications. The paper ends with a discussion of how the process used by the Cornell University-University of California, San Francisco team can be applied to the selection and development of behavioral interventions for other psychiatric disorders.

Targeted versus tailored multimedia patient engagement to enhance depression recognition and treatment in primary care: randomized controlled trial protocol for the AMEP2 study

BACKGROUND

Depression in primary care is common, yet this costly and disabling condition remains underdiagnosed and undertreated. Persisting gaps in the primary care of depression are due in part to patients' reluctance to bring depressive symptoms to the attention of their primary care clinician and, when depression is diagnosed, to accept initial treatment for the condition. Both targeted and tailored communication strategies offer promise for fomenting discussion and reducing barriers to appropriate initial treatment of depression.

METHODS/DESIGN

The Activating Messages to Enhance Primary Care Practice (AMEP2) Study is a stratified randomized controlled trial comparing two computerized multimedia patient interventions -- one targeted (to patient gender and income level) and one tailored (to level of depressive symptoms, visit agenda, treatment preferences, depression causal attributions, communication self-efficacy and stigma)-- and an attention control. AMEP2 consists of two linked sub-studies, one focusing on patients with significant depressive symptoms (Patient Health Questionnaire-9 [PHQ-9] scores ≥ 5), the other on patients with few or no depressive symptoms (PHQ-9 < 5). The first sub-study examined effectiveness of the interventions; key outcomes included delivery of components of initial depression care (antidepressant prescription or mental health referral). The second sub-study tracked potential hazards (clinical distraction and overtreatment). A telephone interview screening procedure assessed patients for eligibility and oversampled patients with significant depressive symptoms. Sampled, consenting patients used computers to answer survey questions, be randomized, and view assigned interventions just before scheduled primary care office visits. Patient surveys were also collected immediately post-visit and 12 weeks later. Physicians completed brief reporting forms after each patient's index visit. Additional data were obtained from medical record abstraction and visit audio recordings. Of 6,191 patients assessed, 867 were randomized and included in analysis, with 559 in the first sub-study and 308 in the second.

DISCUSSION

Based on formative research, we developed two novel multimedia programs for encouraging patients to discuss depressive symptoms with their primary care clinicians. Our computer-based enrollment and randomization procedures ensured that randomization was fully concealed and data missingness minimized. Analyses will focus on the interventions' potential benefits among depressed persons, and the potential hazards among the non-depressed.

Neighborhood characteristics and depressive symptoms of older people: local spatial analyses

Depressive symptoms in community-dwelling older people significantly increase the risk of developing clinically diagnosable depressive disorders. Knowledge of the spatial distribution of depressive symptoms in the older population can add important information to studies of neighborhood contextual factors and mental health outcomes, but analysis of spatial patterns is rarely undertaken. This study uses spatial statistics to explore patterns of clustering in depressive symptoms using data from a statewide survey of community-dwelling older people in New Jersey from 2006 to 2008. A significant overall pattern of clustering in depressive symptoms was observed at the state level. In a subsequent local clustering analysis, places with high levels of depressive symptoms near to other places with high levels of depressive symptoms were identified. The relationships between the level of depressive symptoms in a place and poverty, residential stability and crime were analyzed using geographically weighted regression. Significant local parameter estimates for the three independent variables were observed. Local parameters for the poverty variable were positive and significant almost everywhere in the state. The significant local parameters for residential stability and crime varied in their association with depressive symptoms in different regions of the state. This study is among the first to examine spatial patterns in depressive symptoms among community-dwelling older people, and it demonstrates the importance of exploring spatial variations in the relationships between neighborhood contextual factors and health outcomes.

Psychometric properties of the GAD-Q-IV and DERS in older, community-dwelling GAD patients and controls

Thirty-seven community-dwelling, older generalized anxiety disorder (GAD) patients and 37 nonanxious controls completed the Generalized Anxiety Disorder Questionnaire for DSM-IV (GAD-Q-IV; Newman et al., 2002), the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004), and other measures of anxiety and depression. The GAD-Q-IV and DERS were assessed for internal consistency reliability, construct validity, and test-retest reliability, with results indicating good psychometric performance. Receiver operating characteristic (ROC) analysis conducted on the full sample suggested that the optimal GAD-Q-IV cutoff for classifying GAD cases was 3.71, with .97 sensitivity and .92 specificity. The cutoff score for classifying those participants with GAD and comorbid conditions was higher, however. ROC analysis with the full sample revealed an optimal DERS cutoff score of 62.5, with .76 sensitivity and .86 specificity. Findings support the use of the GAD-Q-IV and DERS as screening instruments for GAD in older, community-dwelling adults in a research setting.

Yield and costs of direct and stepped screening for depressive symptoms in subjects aged 75 years and over in general practice

OBJECTIVE

To examine yield and costs of two screening methods for depressive symptoms in subjects ≥75 years in general practice.

METHODS

In 73 general practices of 12.144 registered subjects ≥75 years 10.681 could be invited for screening. In the first 31 practices we invited 3797 subjects for direct screening which implied an invitation by letter followed by a home visit to administer the 15-item Geriatric Depression Scale (GDS-15). In the remaining 42 practices 6884 subjects were invited for stepped screening which implied that the GDS-15 was sent by post, followed by a home visit only if the self-administered GDS-15-score was ≥4 points. Being screen-positive for depressive symptoms was defined as an interviewer-administered GDS-15-score ≥5 points. Screening costs were estimated based on results in this study.

RESULTS

Of all registered subjects 707 (5.8%) were already being treated for depression. The yield of direct screening was higher than of stepped screening (2.6% versus 1.9%, p = 0.009), with similar yields for subjects aged 75-79 years and for subjects aged ≥80 years. In a standard GP-practice with 160 subjects ≥75 years estimated total screening costs are about twice as high for direct screening than for stepped screening. Estimated costs per screen positive subject are €350 for direct screening and €250 for stepped screening.

CONCLUSION

Direct screening has a higher yield, but is also more time consuming and more expensive. Whether the extra yield is clinically relevant and worth the extra costs, will depend on the subsequent treatment effect.

Use of mental health care by community-dwelling older adults

OBJECTIVES

To examine relationships between perceived need for care, illness characteristics, attitudes toward care, and probability that older adults will use mental health care (MHC).

DESIGN

Secondary data analysis.

SETTING

The Collaborative Psychiatric Epidemiology Surveys (2001-2003).

PARTICIPANTS

One thousand six hundred eighty-one community-dwelling adults aged 65 and older.

MEASUREMENTS

Self-reported MHC use and perceived need for care in the previous 12 months, previous year and history of mental illness, history of physical illness, attitudes toward care, and sociodemographic characteristics.

RESULTS

Of the entire sample, 6.5% had received some type of MHC in the previous year, although 65.9% of those with major depressive disorder (MDD) and 72.5% with anxiety did not receive MHC. In respondents with previous-year depression or anxiety, use was less likely for those with low World Health Organization Disability Assessment Scale (WHO-DAS) self-care ability. Use was more likely for those with more chronic physical conditions and worse WHO-DAS cognitive capacity. Seventeen percent of those with perceived need for MHC did not receive it. In respondents with perceived need, subthreshold generalized anxiety disorder was associated with lower likelihood of use. Use was more likely for older respondents and those with more household members, at least a high school education, and better self-care ability. Forty-one percent of those who perceived a need for care but did not use it met previous-year diagnostic criteria for anxiety, and 17% met criteria for MDD.

CONCLUSION

Understanding the perceptions that underlie individuals' health care-seeking behavior is an important step toward reducing underuse of MHC by older adults.

Which version of the geriatric depression scale is most useful in medical settings and nursing homes? Diagnostic validity meta-analysis

BACKGROUND

The Geriatric Depression Scale (GDS) has been evaluated in individual studies, but its validity and added value in medical settings and nursing homes is uncertain. Therefore, the authors conducted a meta-analysis, analyzing the diagnostic accuracy of long, short, and ultrashort versions of the GDS and stratified this into those with and without cognitive impairment.

METHODS

A comprehensive search identified 69 studies that measured the diagnostic validity of the GDS against a semistructured psychiatric interview, and of these, 43 analyses (in 36 publications) took place inmedical settings. Twenty-one studies examined the GDS₃₀, 12 studies examined the GDS₁₅, and 3 examined the GDS₄(/)₅. For comparison, the authors also summarized studies examining unassisted clinical judgment. Heterogeneity was moderate to high; therefore, random effects meta-analysis was used.

RESULTS

Across all studies, the prevalence of late-life depression was 29.2% (95% confidence interval [CI] = 24.7%–33.9%), with no difference between inpatients, outpatients, and nursing homes. Diagnostic accuracy of the GDS₃₀ aftermeta-analytic weighting was given by a sensitivity of 81.9% (95% CI = 76.4%–86.9%) and a specificity of 77.7% (95% CI = 73.0%–82.1%). For the GDS₁₅, sensitivity was 84.3% (95% CI = 79.7%–88.4%) and specificity was 73.8% (95% CI = 68.0%–79.2%). For the GDS₄(/)₅, the sensitivity and specificity were 92.5% (95% CI = 85.5%–97.4%) and 77.2% (95% CI = 66.6%–86.3%), respectively. Results were not significantly influenced by the presence of dementia. Concerning added value, when identification using the GDS was compared with routine clinicians’ ability to diagnose late-life depressions, at a prevalence of 30%, of every 100 attendees, the GDS₃₀ would help correctly identify an additional 22 people as depressed but at a cost of 13 additional false positives. The GDS₁₅ performed the same as GDS₃₀ but with 15 false positives. The ultrashort form would help identify an additional 25 true positives with only 10 false positives. Thus, the best option when choosing between versions of the GDS seems to be the GDS₄(/)₅.

CONCLUSION

All versions of the GDS yield potential added value in medical settings, but the GDS₄(/)₅ is the most efficient. In nursing homes, given an absence of data on the GDS₄(/)₅, the GDS₁₅ may be preferred until more studies are reported.

Antidepressant prescribing in older primary care patients in community and care home settings in England and Wales

OBJECTIVE

To compare the prevalence and predictors of antidepressant prescribing in older care home and community residents in England and Wales.

DESIGN

Retrospective analysis of primary care consultation and antidepressant prescribing data.

SETTING

The setting included 326 general (family) practices in England and Wales supplying data to The Health Improvement Network database between 2008 and 2009.

PARTICIPANTS

Participants were 10,387 care home and 403,259 community residents aged 65 to 104.

MAIN OUTCOME MEASURE

Antidepressant prescription in the last 3 months of recorded data for each patient.

RESULTS

Prevalence rates for antidepressant prescribing were 10.3% (95% confidence interval 10%-10.6%) for community and 37.5% (36.2%-38.9%) for care home residents. After excluding low-dose tricyclics (often used for other indications) prevalences were 7.3% (7.1%-7.5%) and 33.6% (32.3%-34.9%) respectively; of these, 21.7% (20.8%-22.6%) of community and 4.8% (3.9%-5.6%) of care home prescriptions were for antidepressants advised as best avoided in this age group. After indirect standardization for age, sex, and chronic disease prevalence, the ratio for prescribing was 2.4 (2.3-2.5) in care homes compared with the community; 28.3% (26.6%-30.1%) of community and 42.5% (39.4%-45.7%) of care home residents prescribed antidepressants had no appropriate recorded indication.

CONCLUSIONS

This national sample confirms the high prevalence of antidepressant prescribing to older people, particularly in care homes, frequently without a documented indication. The strong association found between chronic disease and antidepressant prescribing did not explain the higher care home prescribing rate. Widespread community use of nonrecommended antidepressants is also a concern.

Diagnostic validity and added value of the Geriatric Depression Scale for depression in primary care: a meta-analysis of GDS30 and GDS15

BACKGROUND

The Geriatric Depression Scale (GDS) has been evaluated in hospital settings but its validity and added value in primary care is uncertain. We therefore conducted a meta-analysis analysing the diagnostic accuracy, clinical utility and added value of the GDS in primary care.

METHODS

A comprehensive search identified 69 studies that measured the diagnostic validity of the GDS against a semi-structured psychiatric interview and of these 17 analyses (in 14 publications) took place in primary care. Seven studies examined the GDS(30) and 10 studies examined the GDS(15). Heterogeneity was moderate to high, therefore random effects meta-analysis was used.

RESULTS

Diagnostic accuracy of the GDS(30) after meta-analytic weighting was given by a sensitivity of 77.4% (95% CI=66.3% to 86.8%) and a specificity=65.4% (95% CI=44.2% to 83.8%). For the GDS(15) the sensitivity was 81.3% (95% CI=77.2% to 85.2%) and specificity=78.4% (95% CI=71.2% to 84.8%). The fraction correctly identified (also known as efficiency) by the GDS(15) was significantly higher than the GDS(30) (77.6% vs 71.2%, Chi(2)=24.8 P<0.0001). The clinical utility of both the GDS(30) and GDS(15) was "poor" for case-finding (UI+ 0.29, UI+ 0.32 respectively). However the GDS(15) was rated as "good" for screening (UI- 0.75) whereas the GDS(30) was "adequate" (UI- 0.60). Concerning added value, when identification using the GDS was compared with general practitioners' ability to diagnose late-life depressions unassisted by tools, at a prevalence of 15% the GDS(30) had no added benefit whereas the GDS(15) helped identify an additional 4 cases per 100 primary care attendees and also helped rule-out an additional 4 non-cases per 100 attendees. Thus we estimate the potential gain of the GDS(15) in primary care to be 8% over unassisted clinical detection but at a cost of 3-4 minutes of extra time per appointment.

CONCLUSION

The GDS yields potential added value in primary care. We recommend the GDS(15) but not the GDS(30) in the diagnosis of late-life depression in primary care.

Mental distress and service utilization among help-seeking, community-dwelling older adults

BACKGROUND

This study aimed to characterize healthcare and human services utilization among mentally distressed and non-distressed clients receiving in-home care management assessment by aging services provider network (ASPN) agencies in the U.S.A.

METHODS

A two-hour research interview was administered to 378 English-speaking ASPN clients aged 60+ years in Monroe County, NY. A modified Cornell Services Index measured service utilization for the 90 days prior to the ASPN assessment. Clients with clinically significant anxiety or depressive symptoms were considered distressed.

RESULTS

ASPN clients utilized a mean of 2.93 healthcare and 1.54 human services. The 42% of subjects who were distressed accessed more healthcare services (e.g. mental health, intensive medical services) and had more outpatient visits and days hospitalized than the non-distressed group. Contrary to expectations, distressed clients did not receive more human services. Among those who were distressed, over half had discussed their mental health with a medical professional in the past year, and half were currently taking a medication for their emotional state. A far smaller proportion had seen a mental health professional.

CONCLUSIONS

In the U.S.A., aging services providers serve a population with high medical illness burden and medical service utilization. Many clients also suffer from anxiety and depression, which they often have discussed with a medical professional and for which they are receiving medications. Few, however, have seen a mental health specialist preceding intake by the ASPN agency. Optimal care for this vulnerable, service intensive group would integrate primary medical and mental healthcare with delivery of community-based social services for older adults.

Mental health treatment seeking among older adults with depression: the impact of stigma and race

OBJECTIVE

Stigma associated with mental illness continues to be a significant barrier to help seeking, leading to negative attitudes about mental health treatment and deterring individuals who need services from seeking care. This study examined the impact of public stigma (negative attitudes held by the public) and internalized stigma (negative attitudes held by stigmatized individuals about themselves) on racial differences in treatment-seeking attitudes and behaviors among older adults with depression.

METHOD

Random digit dialing was utilized to identify a representative sample of 248 African American and white older adults (older than 60 years) with depression (symptoms assessed by the Patient Health Questionnaire-9). Telephone-based surveys were conducted to assess their treatment-seeking attitudes and behaviors and the factors that impacted these behaviors.

RESULTS

Depressed older adult participants endorsed a high level of public stigma and were not likely to be currently engaged in or did they intend to seek mental health treatment. Results also suggested that African American older adults were more likely to internalize stigma and endorsed less positive attitudes toward seeking mental health treatment than their white counterparts. Multiple regression analysis indicated that internalized stigma partially mediated the relationship between race and attitudes toward treatment.

CONCLUSION

Stigma associated with having a mental illness has a negative influence on attitudes and intentions toward seeking mental health services among older adults with depression, particularly African American elders. Interventions to target internalized stigma are needed to help engage this population in psychosocial mental health treatments.

Cognitive and daily functioning in older adults with vegetative symptoms of depression

OBJECTIVES

In primary care 50-95% of patients with depression present with vegetative symptoms (VS). Based on the extant literature, older adults showing VS (but no dysphoria) may show functional impairment but this hypothesis has not been empirically tested. The goal of this study was to examine neurocognitive and daily functioning of elderly patients showing exclusively VS in comparison with patients presenting with VS and dysphoria.

METHODS

Seven hundred and eighty-seven primary care patients received measures of neurocognition and daily functioning. Neurocognition was measured with the repeatable battery for the assessment of neuropsychological status (RBANS). Three groups were compared: (1) patients with two or more VS of depression without dysphoria (VS - D), (2) patients with at least one VS and dysphoria (VS + D), and (3) comparison patients without multiple VS or dysphoria.

RESULTS

Nearly one third of the sample (31%) fell into the VS - D group, whereas 15% fell into the VS + D group. Both VS groups showed poorer neurocognition and activities of daily living than comparisons. Only one subtest of the RBANS (i.e., picture naming) showed a significant difference between VS + D and VS - D, and there was no significant difference on daily functioning. VS - D patients reported less frequent past history of depression and endorsed less anxiety compared to VS + D.

CONCLUSIONS

Elderly patients presenting with clusters of VS with or without dysphoria show poorer neurocognitive and functional performance. Relative poorer cognition and daily functioning in VS - D are potential harbingers of further decline and consistent with under-reporting of sadness in older age.

Perceived barriers to mental health care and goal setting among depressed, community-dwelling older adults

OBJECTIVE

Older adults are particularly vulnerable to the deleterious effects of depression and tend to underutilize mental health services. The current study aims to characterize the perceived barriers to care and goal setting in a sample of depressed, community-dwelling older adults.

METHODS

We report on the association among perceived barriers to care, goal setting and accepting a mental health referral using a subset of data from a larger study. The Patient Health Questionnaire (PHQ-9) was used to assess depressive symptoms.

RESULTS

Forty-seven participants completed the study (Mean age = 82, SD = 7.8, 85% female). Accessing and paying for mental health treatment were the barriers most frequently cited by participants. Clinical improvement and improved socialization were most cited goals. In bivariate associations, participants who set goals (chi(2) = 5.41, p = 0.02) and reported a logistic barrier (chi(2) = 5.30, p = 0.02) were more likely to accept a mental health referral.

CONCLUSION

Perceived barriers to care and goal setting appear to be central to accepting a mental health referral among community dwelling older, depressed adults. Developing interventions that can be used to increase mental health service utilization of older adults is necessary.

Resilience: resistance factor for depressive symptom

The purpose was to explore influence of resilience on the willingness of African Americans aged 65 and over to seek mental health care for depressive symptoms. Specifically, the study examined relationships between personal resilience and willingness of undiagnosed, community dwelling older adults to seek mental health care for depressive symptoms. A cross-sectional, correlational, causal modelling design was used to study older African Americans (N= 158; 121 women and 37 men) recruited from churches, retirement organizations and senior nutrition centres. Participants completed study instruments to measure depressive symptoms, resilience, willingness to seek mental health care, and general demographics information. Descriptive statistics and multiple regression analyses were preformed. Depressive symptoms and resilience accounted for 15.4% of the willingness to seek mental health care variance; extraction of resilience lowered variance to 0.9%. A direct, predictive relationship between resilience and willingness to seek mental health care was documented. Understanding resilience and willingness to seek mental health care supports future research for interventions that bolster resilience in older adults. Identifying the influence of resilience on such willingness may provide direction for developing interventions for older African Americans and may be applicable to vulnerable, marginalized and minority older adults worldwide.

Mental health services use: Baltimore epidemiologic catchment area follow-up

OBJECTIVE

To examine the patterns of previous and current mental health services use among older adults in the Baltimore Epidemiologic Catchment Area Follow-up. Examination of a recent cohort of older adults is important because patterns of utilization may have changed due to treatment advances, changes in mental healthcare services, and greater mental health awareness.

DESIGN

A population-based longitudinal survey.

SETTING

Continuing participants in a study of community-dwelling adults who were living in East Baltimore in 1981.

PARTICIPANTS

In all, 1,067 adults for whom complete data were available.

MEASUREMENTS

Separately, and before the mental health assessments were made, participants were asked about use of health services. Cognitive status and physical health were assessed using standardized instruments. Mental disorders were assessed using the Diagnostic Interview Schedule.

RESULTS

Compared with adults aged 40-59 years in 2004, adults aged 60 years and older were less likely to report specialty mental health services versus general medical care without a mental health component (adjusted odds ratio = 0.28, 95% confidence interval [0.14-0.56]). Multivariate models controlled for potentially influential characteristics including major depression or depression associated with recent bereavement, anxiety disorders, and past use of mental health services.

CONCLUSION

Adults aged 60 years and older are approximately one third as likely to consult a specialist in mental health compared with adults aged 40-59 years even accounting for other factors associated with differential use of services. Our study strengthens evidence that the primary care remains important for the treatment of psychiatric disorders in the elderly.

Effect of depression on health care utilization in patients with end-stage renal disease treated with hemodialysis

BACKGROUND AND OBJECTIVES

Depression is regarded as the most common psychiatric abnormality in patients on hemodialysis (HD) for end-stage renal disease (ESRD). Although several studies have demonstrated a relationship between depression and utilization of health care in ESRD and other chronic illnesses in developing countries, such evidence from hemodialysis patients is lacking in Iran. This study aims to investigate the effect of depression on health care utilization among Iranian hemodialysis patients.

DESIGN

A longitudinal study.

SETTING

Baqiyatallah Hospital (Tehran, Iran) between 2005 and 2006.

PATIENTS

Of the 70 enrolled hemodialysis patients, 68 finished the study including 19 depressed and 49 non-depressed ones according to the Hospital Anxiety and Depression Scale (HADS).

MEASUREMENTS

The subjects' health care utilization in a six-month period was prospectively assessed by recording the hospital admission and home nurse visits, outpatient physician visits, and patients' emergency department visits for any medical reason. The results were subsequently compared between the study groups.

RESULTS

A higher hospital admission rate (94.7% vs. 55.1%, p=.002; Pearson's chi-square test) as well as a higher likelihood of emergency department visits (73.7% vs. 40.8%, p=0.002; Pearson's chi-square test) was seen in depressed patients. The frequencies of the other types of health care utilization were not statistically different between the two groups (p>0.05, Pearson's chi-square test).

CONCLUSION

Depression in hemodialysis patients is associated with higher rate of hospital admission, and prospective studies should be conducted to assess whether treatment of depression will decrease health care utilization in these patients.

Depressive symptoms and suicidal ideation among older adults receiving home delivered meals

OBJECTIVE

Homebound older adults may be vulnerable to the deleterious impact of untreated depression. Yet because these elders are difficult to reach, there is little data on the rates of depressive symptoms and suicidal ideation among this group. The objective of this study is to document the rates of depression and correlates among a population of homebound elders.

METHODS

Using a community based participatory research partnership, we implemented a routine screening for depressive symptoms and suicidal ideation among older recipients of Westchester County's home meal program. Older adults enrolled in the home delivered meal program were administered the Physician Health Questionnaire-9 (PHQ-9), and questions to assess pain, falls, alcohol abuse and perceived emotional distress.

RESULTS

In our sample of 403 meal recipients, 12.2% of older adults reported clinically significant depression (PHQ-9 > 9) and 13.4% reported suicidal thoughts. One-third of recipients with significant depressive symptoms were currently taking an antidepressant. Almost one-third of older adults who endorsed suicide ideation did not report clinically significant depressive symptoms. Among men, suicidal thoughts were associated with chronic pain and greater depression severity, whereas pain was not a predictor of suicidal thoughts among women.

CONCLUSION

More than one in nine elders suffer from depression; most are untreated with one-third undertreated. Through partnerships between public agencies that provide age related services and academic investigators there is an opportunity for improved detection of unmet mental health needs. Future research should explore innovative models to improve access to mental health services once unmet need is detected.

Effectiveness of problem-solving therapy for older, primary care patients with depression: results from the IMPACT project

PURPOSE

We compared a primary-care-based psychotherapy, that is, problem-solving therapy for primary care (PST-PC), to community-based psychotherapy in treating late-life major depression and dysthymia.

DESIGN AND METHODS

The data here are from the IMPACT study, which compared collaborative care within a primary care clinic to care as usual in the treatment of 1,801 primary care patients, 60 years of age or older, with major depression or dysthymia. This study is a secondary data analysis (n = 433) of participants who received either PST-PC (by means of collaborative care) or community-based psychotherapy (by means of usual care).

RESULTS

Older adults who received PST-PC had more depression-free days at both 12 and between 12 and 24 months (beta = 47.5, p <.001; beta = 47.0, p <.001), and they had fewer depressive symptoms and better functioning at 12 months (beta(dep) = -0.36, p <.001; beta(func) = -0.94, p <.001), than those who received community-based psychotherapy. We found no differences at 24 months.

IMPLICATIONS

Results suggest that PST-PC as delivered in primary care settings is an effective method for treating late-life depression.

Antidepressant use in nonmajor depression: secondary analysis of a program to encourage active, rewarding lives for seniors (PEARLS), a randomized controlled trial in older adults from 2000 to 2003

BACKGROUND

It is estimated that major depressive disorder affects 0.9% of community-dwelling older adults in the United States. However, as many as 18% of older US adults reportedly suffer from depressive symptoms that do not necessarily fit the criteria for major depressive disorder (eg, dysthmia, minor depression).

OBJECTIVES

The goals of this study were to describe patterns of antidepressant medication use in older adults with dysthymia or minor depression and to examine factors associated with the use of antidepressants at baseline.

METHODS

This was a secondary analysis using cross-sectional data collected during a randomized controlled trial conducted from 2000 through 2003. It involved community senior service agencies and in-home visits in Seattle, Washington. Adults aged >or=60 years who had minor depression or dysthymia and were receiving services through community senior service agencies or living in senior public housing were included. Study participants were classified as users or nonusers of antidepressants. Prescription medication use in the past 2 weeks was assessed at baseline and 6 and 12 months. Medication name, dose, and directions were recorded from the medication label. Logistic regression was used to examine variables associated with baseline antidepressant use.

RESULTS

A total of 138 patients (mean age, 73.00 years) were included; the majority of study participants were female (779.00%). Overall, 42.33% were nonwhite (34.3% black, 4.4% Asian, 1.5% American Indian/Alaskan Native, 0.7% Hispanic, and 1.5% other). At baseline, 36.2% of study participants (n = 50) were using antidepressants. Selective serotonin reuptake inhibitors were the most common class of antidepressants, used by 62.00%, 70.22%, and 71.11% of antidepressant users at baseline, 6, and 12 months, respectively. However, nortriptyline was the most common antidepressant at baseline, taken by 20.00% of antidepressant users. Use of other prescription medications was associated with antidepressant use at baseline.

CONCLUSIONS

We found antidepressant use to be low in these relatively poor, community-dwelling, ethnically diverse older adults with dysthymia and minor depression in 2000 through 2003, with 36.22% of participants using antidepressants at baseline. Antidepressant users were more likely to be taking other prescription medications than nonusers.

The impact of cost sharing on antidepressant use among older adults in British Columbia

OBJECTIVE

Antidepressant therapies are underused among older adults and could be further curtailed by patient cost-sharing requirements. The authors studied the effects of two sequential cost-sharing policies in a large, stable population of all British Columbia seniors: change from full prescription coverage to 10-25 dollars copayments (copay) in January 2002 and replacement with income-based deductibles and 25% coinsurance in May 2003.

METHODS

PharmaNet data were used to calculate monthly dispensing of antidepressants (in imipramine-equivalent milligrams) among all British Columbia residents age 65 and older beginning January 1997 through December 2005. Monthly rates of starting and stopping antidepressants were calculated. Population-level patterns over time were plotted, and the effects of implementing cost-sharing policies on antidepressant use, initiation, and stopping were examined in segmented linear regression models.

RESULTS

Implementation of the copay policy was not associated with significant changes in level of antidepressant dispensing or the rate of dispensing growth. Subsequent implementation of the income-based deductible policy also did not lead to a significant change in dispensing level but led to a significant (p=.02) decrease in the rate of growth of antidepressant dispensing. The copay policy was associated with a significant (p=.01) drop in the frequency of antidepressant initiation among persons with depression. Income-based deductibles reduced the rate of increase in antidepressant initiation over time. Implementation of the copay and income-based deductible policies did not have significant effects on stopping rates.

CONCLUSIONS

Introducing new forms of medication cost sharing appears to have the potential to reduce some use and initiation of antidepressant therapy by seniors. The clinical consequences of such reduced use need to be clarified.

Higher burden of depression among older women: the effect of onset, persistence, and mortality over time

CONTEXT

The prevalence of depression is disproportionately higher in older women than men, yet the reasons for this sex difference are not clear.

OBJECTIVE

To determine whether the higher burden of depression among older women than men might be attributable to sex differences in the onset (ie, first or recurrent episodes) or persistence of depression and/or to differential mortality among those who are depressed.

DESIGN

Prospective cohort study.

SETTING

General community in greater New Haven, Connecticut, from March 23, 1998, to August 31, 2005.

PARTICIPANTS

A total of 754 persons, 70 years or older, who were evaluated at 18-month intervals for 72 months.

MAIN OUTCOME MEASURES

The 3 outcome states were depressed, nondepressed, and death, with scores of 20 or more and less than 20 on the Center for Epidemiological Studies Depression Scale denoting depressed and nondepressed, respectively. The association between sex and the likelihood of 6 possible transitions (namely, from nondepressed or depressed to nondepressed, depressed, or death) was evaluated over time.

RESULTS

The prevalence of depression was substantially higher among women than men at each of the 5 time points (P < .001). In most cases, transitions between the nondepressed and depressed states were characterized by moderate to large absolute changes in depression scores (ie, > or = 10 points). Adjusting for other demographic characteristics, women had a higher likelihood of transitioning from nondepressed to depressed (odds ratio, 2.02; 95% confidence interval, 1.39-2.94) and a lower likelihood of transitioning from depressed to nondepressed (odds ratio, 0.27; 95% confidence interval, 0.13-0.56) or death (odds ratio, 0.24; 95% confidence interval, 0.09-0.60).

CONCLUSION

Among older persons, the higher burden of depression in women than men seems to be attributable to a greater susceptibility to depression and, once depressed, to more persistent depression and a lower probability of death.

The influence of specific chronic somatic conditions on the care for co-morbid depression in general practice

BACKGROUND

Limited information exists on the relationship between specific chronic somatic conditions and care for co-morbid depression in primary care settings. Therefore, the present prospective, general practice-based study examined this relationship.

METHOD

Longitudinal data on morbidity, prescribing and referrals concerning 991 patients newly diagnosed with depression by their general practitioner (GP) were analysed. The influence of a broad range of 13 specific chronic somatic conditions on the initiation of any depression care, as well as the prescription of continuous antidepressant therapy for 180 days, was examined. Multilevel logistic regression analysis was used to control for history of depression, psychiatric co-morbidity, sociodemographics and interpractice variation.

RESULTS

Multilevel analysis showed that patients with pre-existing ischaemic heart disease (72.1%) or cardiac arrhythmia (59.3%) were significantly less likely to have any depression care being initiated by their GP than patients without chronic somatic morbidity (88.0%). No other specific condition had a significant influence on GP initiation of any care for depression. Among the patients being prescribed antidepressant treatment by their GP, none of the conditions was significantly associated with being prescribed continuous treatment for 180 days.

CONCLUSIONS

Our study indicates that patients with ischaemic heart disease or cardiac arrhythmia have a lower likelihood of GP initiation of any care for depression after being newly diagnosed with depression by their GP. This finding points to the importance of developing interventions aimed at supporting GPs in the adequate management of co-morbid depression in heart disease patients to reduce the negative effects of this co-morbidity.

Depression in nursing homes: ensuring adequate treatment

Studies have shown a high prevalence of depressive disorders among nursing home residents around the world. Various losses in old age may precipitate depression, and physical illness and disability are major factors that contribute to the development and persistence of depressive disorders. Demoralization (existential distress) is common. Recognition of what a nursing home resident has lost is often a key to developing plans for management. The prognosis for recovery from depression is worse for patients who face an ongoing distressing situation or physical condition. For ongoing loss-related distress, including sadness about loss of health, it is important for patients to ventilate feelings, and to either re-acquire what is lost or to grieve and then adapt to the new situation. For major depression with melancholia, psychotic depression and bipolar disorders, biological treatments are of prime importance. Non-melancholic major depression is best treated with a combination of antidepressants and psychosocial therapies, the latter being particularly indicated when the depression has been precipitated by stressful and depressing events or situations. Psychosocial and environmental interventions are important in all types of depression and may prove more effective than the use of antidepressants for milder disorders. There has been a welcome increase in the recognition of depression in nursing homes and in the prescription of newer antidepressants, but the published evidence to date does not allow definitive recommendations regarding which antidepressants to use in this setting. Outcome research is needed to assess antidepressant efficacy and to better plan multifaceted treatment strategies for depressions of varying types and aetiologies among nursing home residents.

Recommendations for treating depression in community-based older adults

OBJECTIVE

To present recommendations for community-based treatment of late-life depression to public health and aging networks.

METHODS

An expert panel of mental health and public health researchers and community-based practitioners in aging was convened in April 2006 to form consensus-based recommendations. When making recommendations, panelists considered feasibility and appropriateness for community-based delivery, as well as strength of evidence on program effectiveness from a systematic literature review of articles published through 2005.

RESULTS

The expert panel strongly recommended depression care management-modeled interventions delivered at home or at primary care clinics. The panel recommended individual cognitive behavioral therapy. Interventions not recommended as primary treatments for late-life depression included education and skills training, comprehensive geriatric health evaluation programs, exercise, and physical rehabilitation/occupational therapy. There was insufficient evidence for making recommendations for several intervention categories, including group psychotherapy and psychotherapies other than cognitive behavioral therapy.

CONCLUSIONS

This interdisciplinary expert panel determined that recommended interventions should be disseminated throughout the public health and aging networks, while acknowledging the challenges and obstacles involved. Interventions that were not recommended or had insufficient evidence often did not treat depression primarily and/or did not include a clinically depressed sample while attempting to establish efficacy. These interventions may provide other benefits, but should not be presumed to effectively treat depression by themselves. Panelists also identified primary prevention of depression as a much under-studied area. These findings should aid individual clinicians as well as public health decision makers in the delivery of population-based mental health services in diverse community settings.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Unipolar Depressive Disorders in Primary Care

These practical guidelines for the biological treatment of unipolar depressive disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the treatment of unipolar depressive disorders and offer practical recommendations for general practitioners encountering patients with these conditions. The guidelines cover disease definition, classification, epidemiology and course of unipolar depressive disorders, and the principles of management in the acute, continuation and maintenance phase. They deal primarily with biological treatment (including antidepressants, other psychopharmacological and hormonal medications, electroconvulsive therapy, light therapy).

Project IMPACT: a report on barriers and facilitators to sustainability

Project IMPACT is a collaborative care intervention to assist older adults suffering from major depressive disorder or dysthymia. Qualitative research methods were used to determine the barriers and facilitators to sustaining IMPACT in a primary care setting. Strong evidence supports the program's sustainability, but considerable variation exists in continuation strategies and operationalization across sites. Sustainability depended on the organizations' support of collaborative care models, the availability of staff trained in the intervention, and funding. The intervention's success was the most important sustainability factor, as documented by outcome data and through the "real world" experience of treating patients with this intervention.

Depression in assisted living is common and related to physical burden

OBJECTIVE

The objective of this study was to obtain a direct estimate of the prevalence of depression, its associated factors, and rates of treatment among residents of assisted living (AL) facilities in central Maryland.

METHOD

One hundred ninety-six AL residents were recruited from 22 (10 large and 12 small) randomly selected AL facilities in the city of Baltimore and seven Maryland counties. Chart review, staff and family history, comprehensive in-person resident evaluation, and the Cornell Scale for Depression in Dementia (CSDD) were administered by an experienced team of geriatric psychiatry clinicians. Those scoring >7 on the CSDD, a cut point repeatedly associated with poor outcomes, were considered clinically depressed.

RESULTS

Participants had an average age of 86 years, most were female and widowed, and 68% met consensus criteria for dementia. Twenty-four percent (47 of 196) of the sample was depressed. In bivariate analyses, depression was significantly related to medical comorbidity, need for activities of daily living (ADLs) assistance, more days spent in bed, and less participation in organized activities. After controlling for pertinent covariates in a regression model, only need for ADL assistance remained significantly associated with depression. Forty-three percent of those currently depressed were receiving antidepressants and were more likely to receive them if they lived in a large AL facility. Sixty percent of depressed residents had no regular source of psychiatric care.

CONCLUSIONS

In the first clinical study implemented by geriatric psychiatry professionals in AL, depression was found to be common, undertreated, and related to physical burden. AL is a rapidly growing segment of long-term care and represents an important setting in which to find and treat serious depression.

Primary care physician office visits for depression by older Americans

BACKGROUND

Older patients mostly receive depression care from primary care physicians, but it is not known whether depression treatment is primarily received from family/general practice physicians or internal medicine physicians and whether the type of depression treatment offered varies between these types of primary care physicians.

OBJECTIVE

To assess what proportion of visits for depression are to family/general practice physicians or to internal medicine physicians and whether the type of depression treatment offered varies by primary care physician specialty.

DESIGN

Data from the 2000 and 2001 National Ambulatory Medical Care Surveys, a nationally representative survey of visits to office-based practices using clustered sampling, were used.

PARTICIPANTS

Office-based physician practices in the United States.

RESULTS

There were an estimated 9.8 million visits made to office-based providers by older patients for depression in 2001 to 2002, of which 64% were to primary care physicians. Visits to primary care providers were evenly split between Internists and family/general practice physicians. There was no significant difference in the rate of antidepressant prescribing between visits to Internists versus family/general practice (55.9% vs 48.0%; P = .42). Mental health counseling or psychotherapy was offered more often during visits to family/general practice physicians than to Internists (39.4% vs 14.0%; P = .07).

CONCLUSIONS

Visits for depression by elderly patients continue to take place in primary care settings to both family/general practice physicians and Internists. Interventions aimed at improving depression care in primary care should focus on both types of primary care physicians and emphasize improving rates of diagnosis and referral for counseling or psychotherapy as a viable treatment option.

Utilization of mental health care services among older adults with depression

Despite the availability of effective treatments for late life depression, data indicate that only a small minority of adults over the age of 65 years with depression access any kind of care for emotional or mental health problems. Using data from the Canadian Community Health Survey (Cycle 1.1), we compared patterns of mental health service utilization among middle-aged (45-64 years), younger old (65-74 years), and older old (75 years and older) adults with and without depression and identified predictors associated with accessing different services (n=59,302). Compared to middle-aged adults with depression, individuals aged 65 and older with depression were less likely to report any mental health consultation in the past year and especially unlikely to report consulting with professionals other than a family physician. Age remained a significant predictor of mental health service utilization even after accounting for other relevant variables such as gender, marital status, years of education, depression caseness, and number of chronic medical conditions. Although the prevalence of depression is lower in older age groups, the present study provides compelling evidence that mental health services are particularly underutilized by depressed older adults.

Regional cerebral blood flow in the assessment of major depression and Alzheimer??s disease in the early elderly

BACKGROUND

Alzheimer's disease and major depression are representative diseases that present forgetfulness and a depressive mood. It is often difficult to make a differential diagnosis between the two in the initial phase.

AIM

To evaluate the differential diagnosis method using regional cerebral blood flow patterns with a three-dimensional stereotactic surface projection technique.

METHODS

Twenty early-elderly patients with mild and moderate forgetfulness were studied. Among them, 10 were diagnosed as having major depression (the MD group) and the other 10 as having Alzheimer's disease (the AD group). All patients underwent cerebral perfusion single photon emission computed tomography (SPECT) with [(123)I]iodoamphetamine. A z-score was calculated for each pixel of the cerebral surface. Twenty-one circular regions of interest (ROIs) were placed on the z-score map. The significance of the statistical difference in ROI values between the two groups was determined by using the two-sided Mann-Whitney U-test.

RESULTS

The z-scores for the lateral parietal, lateral temporal, bilateral precuneus and bilateral posterior cingulate gyrus were significantly reduced in the AD group compared with those in the MD group. The z-scores for the lateral frontal, left thalamus and bilateral medial frontal regions were significantly lower in the MD group than in the AD group.

CONCLUSION

Our study demonstrated a difference in regional cerebral blood flow patterns between the early elderly with Alzheimer's disease and those with major depression. All patients were classified into the appropriate categories using discriminant analysis and z-scores of frontal and parietal regions. Brain perfusion SPECT was a useful tool for the differential diagnosis between Alzheimer's disease and major depression.

Enriching geropsychiatric nursing in advanced practice nursing programs

The need for advanced practice nurses with knowledge and skills in geropsychiatric nursing is real and looming larger than ever. By 2030, the number of older adults with major psychiatric illnesses is predicted to reach 15 million. Preparing advanced practice nurses with mental health and geropsychiatric nursing expertise is essential. This paper describes three innovative curricular models for addressing geropsychiatric nursing in graduate advanced practice nursing programs. These models can be implemented with vision, planning, modest resources, and the cooperation of the faculty.

Depression and frequent attendance in elderly primary care patients

OBJECTIVE

The aim of this study is to investigate the association between depression and frequent attendance in elderly primary care patients. Moreover, we compare the prevalence and clinical characteristics of frequent attenders (FAs) in the elderly and the nonelderly patients.

METHODS

This nationwide, cross-sectional, two-phase epidemiological study involved 191 primary care physicians (PCPs) and 1896 patients aged 14 and over. We consider FAs those subjects attending PCP practice more than once a month in the last 6 months. Screening for psychiatric disorders was conducted by using the General Health Questionnaire-12. Subsequently, probable cases were assessed by the PCPs with the WHO ICD-10 Checklist for Depression.

RESULTS

Prevalence value of frequent attendance was 22.4% in the elderly. Depression was associated with frequent attendance in the elderly even after controlling for physical illness and unexplained somatic complaints. The risk for being an FA was more than twofold in the elderly than in the nonelderly (cOR=2.58; 95% confidence interval, 1.97-3.37). Considering subjects without medical illness, depression increased the risk of being an FA fivefold among the elderly and threefold among the nonelderly.

CONCLUSION

Frequent attendance in primary care is associated with depressive disorder in the elderly. Depression seems to play a more important role in determining frequent attendance in the elderly patients in respect to the nonelderly.
