Depression in the elderly: effect on patient attitudes toward life-sustaining therapy.

OBJECTIVE: To determine the effect of depression on preferences for life-sustaining therapy in older persons. DESIGN: A survey comparing depressed, older veterans and a similar, but non-depressed, control group. SETTING: A 490-bed Veterans Affairs teaching hospital. PATIENTS: Medical inpatients over 65 years of age were potential subjects. Patients who were in intensive care, cognitively impaired, unable to communicate, abusing alcohol or drugs, or unable to return for outpatient care were excluded. Ninety-five eligible subjects (29%) refused to participate. Depressed subjects scored >14 on the Geriatric Depression Scale (GDS) and were diagnosed as depressed by a psychiatrist who was blind to the GDS results. Complete data were collected on 50 depressed and 50 control subjects. MAIN OUTCOME MEASURES: A self-administered questionnaire quantified patients' preferences regarding life-saving interventions in their current state of health and in four hypothetical scenarios of serious illness. RESULTS: Depressed subjects desired fewer interventions than control subjects in their current health and in hypothetical scenarios with a good prognosis (P < or = 0.05). There were no differences between groups in poor prognosis scenarios. However, depression did not explain more than 5% of the variance in decision-making in any situation. In good prognosis scenarios, subjects' assessment of quality of life was the most powerful predictor of desire for life-saving interventions, accounting for 9%-17% of the variance (P <0.01). CONCLUSIONS: These results suggest that depression is associated with treatment refusal in situations with a good medical prognosis. Depression, however, is only a weak predictor of treatment refusal. Further research is needed to define which patients would accept medical treatment if effectively treated for depression.     

Psychometric properties of the 15-item geriatric depression scale in functionally impaired, cognitively intact, community-dwelling elderly primary care patients

OBJECTIVES: To examine the psychometric properties of the 15-item Geriatric Depression Scale (GDS-15), a brief depression screening measure. DESIGN: Cross-sectional. SETTING: Nineteen counties in western New York, West Virginia, and Ohio. PARTICIPANTS: Nine hundred sixty functionally impaired, cognitively intact, community-dwelling primary care patients aged 65 and older. MEASUREMENTS: The GDS-15, major depression as measured using the Mini-International Neuropsychiatric Interview, depressed mood, life satisfaction, suicidal ideation, and reported suicide attempts. RESULTS: Exploratory factor analyses suggested a two-factor structure for the GDS-15 in this category of patients, with component subscales assessing depression and positive affect. Cronbach alpha coefficients provide evidence for moderate, although acceptable, internal consistency reliability. Significant associations between the GDS-15 and measures of depressed mood, life satisfaction, and suicidal ideation demonstrated construct validity, whereas acceptable sensitivity and specificity to discriminate between depressed and nondepressed patients demonstrated criterion validity. Internal consistency reliability and construct validity did not differ significantly between patients with low and high functional impairment. A significant weakness of the scale is its low correlation with suicide attempt status. CONCLUSION: In general, this study provides evidence of impressive psychometric properties of the GDS-15 when administered to a sample of functionally impaired, cognitively intact, community-dwelling primary care patients.     

Depression is common and precludes accurate assessment of functional status in elderly patients with congestive heart failure

BACKGROUND: Congestive heart failure (CHF) and depression are independently known to result in physical decline and diminished functional capacity in the general population. The prevalence and relationship of depressive symptoms in CHF to physical limitations has not been objectively examined. METHODS AND RESULTS: The Center for Epidemiological Studies Depression Scale (CES-D) was used to ascertain depressive symptoms in 33 elderly ambulatory individuals with CHF. Self-report assessment of functional status, cardiopulmonary exercise testing (CPX), and measurement of energy expenditure by doubly labeled water and Caltrac Accelerometer (Muscle Dynamics, Torrance, CA) were performed. Depressed and nondepressed groups were compared. Forty-two percent of the patients scored in the depressed range (CES-D score of 16 or greater). There were no differences in demographic variables or severity of illness between the depressed and nondepressed patients. Energy expenditure was comparable across groups. Although obtaining similar maximal heart rate and maximal oxygen consumption (VO2max) on CPX, the depressed group showed less exertion on exercise testing with a significantly lower respiratory quotient (P = .017). CONCLUSION: Depressive symptoms were common and unrelated to the severity of CHF. Although depressed individuals tended to report worse physical functioning than nondepressed individuals, objective assessment of energy expenditure was comparable. Depressed patients appear to underestimate their functional ability. Subsequently, inaccurate assessment of functional status may occur.     

Learned helplessness and depression: a test of the reformulated model

The old model of learned helplessness and depression was compared with the reformulated model. Fifty elderly depressed/nondepressed women were exposed to a number guessing task and were given nonveridical feedback as to their success or failure on the task. As predicted by the reformulated model, significant interaction effects were found. Depressed women attributed failure to lack of ability; they attributed success to luck. In contrast, nondepressed women attributed failure to bad luck and success to high ability. In the second part of the study, the reformulated model's hypothesis was tested regarding personal and universal helplessness. Although it only approached significance it was consistent with the hypothesis; depressed women saw themselves as personally helpless when compared with others for failure outcomes; nondepressed women saw themselves as universally helpless (i.e., everyone would fail the task). A revised clinical treatment model was proposed suggesting an interactionist strategy in treating depression.     

Medical patients’ attitudes toward emotional problems and their treatment

BACKGROUND: Understanding medical patients' attitudes toward emotional problems and their management is crucial to overcoming obstacles to efficient depression treatment. OBJECTIVE: To investigate attitudes toward emotional problems, psychotherapy, antidepressants, alternative treatment approaches, and self-management techniques in depressed and nondepressed medical outpatients. DESIGN: Cross-sectional interview study, including quantitative and qualitative methods. PATIENTS: Eighty-seven depressed subjects (mean age, 41.0 years; 66% female) and 91 nondepressed subjects (mean age, 41.4 years; 67% female) from 7 internal medicine outpatient clinics and 12 family practices (participation rate, 91%). MEASUREMENTS: Depression diagnoses were established using a structured diagnostic interview, and patient attitudes were investigated with open-ended interview questions regarding treatment preferences, factors improving and impairing emotional well-being, and patients' self-management to improve well-being. RESULTS: Among the depressed patients, psychotherapy was the most frequently preferred treatment (29%) and the most common factor reported to improve emotional well-being (36%). Twenty-two percent of the depressed patients desired depression treatment within their current medical system, but requested substantially more time to communicate with their physician. Antidepressants were rarely mentioned as a preferred treatment (6%) or factor improving well-being (11%). Thirty-eight percent of the depressed patients attributed their impaired mood to health problems. Compared with the depressed patients, the nondepressed controls preferred significantly less frequent depression-specific therapies. CONCLUSIONS: The vast majority of medical outpatients prefer treatment approaches for emotional problems that go beyond antidepressant medication therapy. Health care providers should consider providing sufficient time to communicate with their patients, the strong preference for psychotherapy, and an appropriate treatment of comorbid physical conditions.     

Reducing suicidal ideation in depressed older primary care patients

OBJECTIVES: To determine the effect of a primary care-based collaborative care program for depression on suicidal ideation in older adults. DESIGN: Randomized, controlled trial. SETTING: Eighteen diverse primary care clinics. PARTICIPANTS: One thousand eight hundred one adults aged 60 and older with major depression or dysthymia. INTERVENTION: Participants randomized to collaborative care had access to a depression care manager who supported antidepressant medication management prescribed by their primary care physician and offered a course of Problem Solving Treatment in Primary Care for 12 months. Participants in the control arm received care as usual. MEASUREMENTS: Participants had independent assessments of depression and suicidal ideation at baseline and 3, 6, 12, 18, and 24 months. Depression was assessed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (SCID). Suicidal ideation was determined using the SCID and the Hopkins Symptoms Checklist. RESULTS: At baseline, 139 (15.3%) intervention subjects and 119 (13.3%) controls reported thoughts of suicide. Intervention subjects had significantly lower rates of suicidal ideation than controls at 6 months (7.5% vs 12.1%) and 12 months (9.8% vs 15.5%) and even after intervention resources were no longer available at 18 months (8.0% vs 13.3%) and 24 months (10.1% vs 13.9%). There were no completed suicides in either group. Information on suicide attempts or hospitalization for suicidal ideation was not available. CONCLUSION: Primary care-based collaborative care programs for depression represent one strategy to reduce suicidal ideation and potentially the risk of suicide in older primary care patients.     

Suicidal ideation among adolescents with alcohol use disorders during treatment and aftercare

The objectives of this study are to assess the magnitude and course of suicidal ideation during outpatient treatment and aftercare for adolescents with alcohol use disorders (AUD). One hundred seventy-seven adolescents meeting eligibility criteria, including no past 30-day suicidal behavior, participated in 9 weeks of outpatient cognitive-behavioral group therapy. Treatment completers were randomized into: (1) No-Active, (2) In-Person, or (3) Telephone aftercare conditions for a period of 12 weeks. No specific intervention for suicidal behavior was provided during the study. The Suicide Ideation Questionnaire (SIQ-JR, Reynolds, 1988) was administered at baseline, end of treatment, and end of aftercare. The results are as follows, a higher baseline suicidal ideation was associated with higher retention at the end of treatment and through aftercare. The In-Person Aftercare condition showed a significant decrease in suicidal ideation, relative to the No-Active Aftercare condition. There was a trend for similarly reduced severity of suicidal ideation in the Telephone Aftercare condition. In conclusion, the type of aftercare and resulting decrease in AUD may play a role in the reduction in suicidal ideation. The mechanism of change by which suicidal ideation is reduced in adolescents in treatment for AUD needs to be further explored.     

Prevalence and correlates of suicidal ideation in SLE inpatients: Chinese experience

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple organs. Because of double damages of body and mind, SLE patients are in a potential risk of suicide. Many factors may contribute to the occurrence of suicide in SLE: socioeconomic factors, medical factors, mental health, family support and coping style. This study aims to investigate the prevalence and correlates of suicidal ideation in SLE inpatients in China in order to determine whether they had risk of suicide, and if so, what factors should be paid more attention to prevent suicide in wards. A total of 285 SLE patients were interviewed with questionnaires on suicidal ideation and socio-demographic characteristics, Beck Depression Inventory (BDI), Family APGAR and Trait Coping Style Questionnaire (TCSQ). Disease activity was assessed with SLE Disease Activity Index. The other medical information was collected from the patients’ medical records. In total, 34.4% of SLE patients had current suicidal ideation. Significant individual risk factors for current suicidal ideation in SLE patients included having religious belief, heavy self-reported financial burdens, long duration of SLE, low level of family functioning and negative coping style. And in the presence of these risk factors, being separated, divorced or widowed, having premorbid suicidal ideation and depression were independent predictors of suicidal ideation. In summary, the rate of suicidal ideation in SLE patients in China is higher than that in other countries. Factors that contribute to risk of suicidal ideation include social and cultural domains and physical and psychological health. Although the association of suicidal ideation to religions and medical factors is still to be investigated, these findings may give some references to suicide prevention efforts for SLE patients in China.     

Physicians are less willing to treat suicidal ideation in older patients

OBJECTIVE: Older adults have the highest rate of suicide of any age group, and reducing the number of late-life suicides has become a national priority. The objective of this study was to determine if an age bias exists among primary care physicians when they contemplate treating suicidal patients. DESIGN: Primary care providers were mailed one of two case vignettes of a suicidal, depressed patient. The only difference between the two vignettes was the age of the patient (38 or 78 years old) and employment status (employed vs retired as a factory worker). A questionnaire was included to determine provider recognition of suicidal ideation, and a scale was designed to detect willingness to treat the vignette patient. SETTING/PARTICIPANTS: Physicians were selected randomly from the University of California, San Francisco physician roster and invited to participate in the study. A total of 342 physicians (63% response rate), including specialists, responded to the mailings. For this study, the responses of 215 primary care physicians were analyzed. INTERVENTION: The randomly assigned experimental group received a vignette of a geriatric, retired patient who was depressed and suicidal (n = 100 participants). The control group received an identical but younger, employed patient (n = 115 participants). MEASUREMENTS: A 21-item Suicidal Patient Treatment Scale measured willingness to treat the suicidal patient. RESULTS: The physicians in this study recognized depression and suicidal risk in both the adult and the geriatric vignette, but they reported less willingness to treat the older suicidal patient compared with the younger patient. The physicians were more likely to feel that suicidal ideation on the part of the older patient was rational and normal. They were less willing to use therapeutic strategies to help the older patient, and they were not optimistic that psychiatrists or psychologists could help the suicidal patient. CONCLUSIONS: This study suggests that primary care physicians are capable of recognizing suicidal ideation but are less willing to treat it if the patient is older and retired. Future research needs to determine etiologic factors for this age bias.     

Evaluation of the relationship between depression and fibromyalgia syndrome: why aren't all patients depressed?

OBJECTIVE: To examine the relationship between fibromyalgia syndrome (FM) and depression by determining the set of factors that differentiate FM patients with and without depressive disorders. METHODS: A sample of 69 patients with FM underwent a standardized tender point examination and a semistructured psychological interview and completed a set of self-report inventories. RESULTS: Of the sample, 39 met criteria for depressive disorder and 30 did not. Depressed patients with FM were significantly more likely to live alone, report elevated functional limitations, and display maladaptive thoughts than nondepressed patients. Nondepressed patients were significantly more likely to have received prior physical therapy than depressed patients. Pain severity, numbers of positive tender points, and pain intensity of tender points and control points did not differentiate the depressed and nondepressed patients. Discriminant analysis revealed that living status, the perception of functional limitations, maladaptive thoughts, and physical therapy treatment together identified diagnoses of depressive disorders for 78% of the patients. CONCLUSION: Concurrent depressive disorders are prevalent in FM and may be independent of the cardinal features of FM, namely, pain severity and hypersensitivity to pressure pain, but are related to the cognitive appraisals of the effects of symptoms on daily life and functional activities.     

Limiting resuscitation: emerging policy in the emergency medical system

Patients, families, and physicians frequently decide that a hospitalized patient will forgo cardiopulmonary resuscitation and document this decision with a do-not-resuscitate (DNR) order. In community settings (home, nursing home, hospice), these orders may conflict with paramedics' standing orders to provide cardiopulmonary resuscitation whenever it is medically indicated. We did a nationwide telephone survey of state offices for coordination of emergency medical services (EMS) to see how the states deal with this potential conflict. We identified eight states that have specific policies enabling EMS personnel to accept DNR orders for patients being transported by ambulance. State officials identified administrative complexities and legal concerns as the primary barriers to enacting prehospitalization DNR policies. We also identified 21 local EMS systems that have developed policies for accepting orders to withhold life-sustaining treatment. Four types of policy models, characterized according to procedure for validating DNR orders and telephone accessing the EMS system, show that regulatory reform can address policy barriers in the absence of enabling legislation.     

Suicidality among nonadherent patients living with HIV in Buenos Aires,Argentina: prevalence and correlates

Of those in the general population hospitalized for suicidal ideation and suicide attempts in Argentina, many reattempt suicide and are readmitted. However, few studies in Argentina have examined suicidal ideation and suicide-related behaviors among people living with HIV (PLHIV) and none have examined these factors among nonadherent PLHIV, though the prevalence of suicidal ideation in this group may be higher than in the general population and also than in other groups of PLHIV. This study of PLHIV in Buenos Aires, Argentina, examined the correlates of suicidal ideation in nonadherent PLHIV. Nonadherent patients with HIV (N?=?118) were recruited from two clinics providing outpatient healthcare services to PLHIV in Buenos Aires, Argentina. Participants completed assessments on demographic characteristics, depression and suicidality, stigma, and self-efficacy. Participants were HIV-infected men (51%) and women (49%) with a median age of 40 years (IQR?=?11). About half had completed high school or more, two-thirds were employed, and had a mean monthly income of 4196.79 (SD?=?3179.64) Argentine pesos (USD$221). Thirty-three (28% [95% CI 20.3, 37.3]) participants reported suicidal ideation in the past two weeks, and one-third (35.6% [27.1, 44.9]) reported lifetime suicidal ideation. In bivariate analyses, attending a public clinic, being female, younger, unemployed, and experiencing greater stigma and depression were associated with suicidal ideation. In multivariable logistic regression, stigma interacted with the number of years since HIV diagnosis to predict suicidal ideation. The impact of stigma on suicidal ideation decreased with time since HIV diagnosis, suggesting that suicidal ideation may arise following HIV diagnosis due to perception of HIV-related stigma. Interventions to reduce perceived stigma during the period following HIV diagnosis may reduce suicidal ideation in this population. Organizational initiatives that explore HIV stigma microagressions in the healthcare setting may be needed to optimize health outcomes.     

Personality traits and suicidal behavior and ideation in depressed inpatients 50 years of age and older

Completed suicide may be the most preventable lethal complication of depressive disorders in older adults. Identification of risk factors for suicidal behavior has therefore become a major public health priority. Using data collected on 81 depressed patients 50 years of age and older, we report analyses designed to determine the associations between the personality traits that constitute the Five Factor Model of personality and measures of suicidal behavior and ideation. We hypothesized that low Extraversion would be associated with a lifetime history of attempted suicide, and high Neuroticism would be associated with suicidal ideation. Results were generally consistent with the hypotheses. We also observed a relationship between Openness to Experience and suicidal ideation. These findings suggest that longstanding patterns of behaving, thinking, and feeling contribute to suicidal behavior and thoughts in older adults and highlight the need to consider personality traits in crafting and targeting prevention strategies.     

Depressed mood and body mass index as predictors of muscle strength decline in old men

OBJECTIVE: To study depressed mood as a predictor of strength decline within body weight categories over a 3-year follow-up period. DESIGN: A prospective cohort study over 3 years. SETTING: Honolulu, Hawaii. PARTICIPANTS: The subjects were 2275 men participating in the Honolulu Heart Program with an average age of 77.1 years (range 71-92 years), who were not cognitively impaired at baseline (Exam 4), and who participated in maximal hand grip strength measurements at baseline and 3 years later (Exam 5). MEASUREMENTS: Hand grip strength was measured using a dynamometer. Depressive symptoms were studied using an 11-item version of Center for Epidemiologic Studies Depression Scale with 9 as a cutoff. Body weight categories were formed on the basis of body mass index (BMI) (BMI = weight/height2; underweight: BMI < 20; normal weight: BMI 20-24.99, overweight: BMI > or = 25). MAIN RESULTS: At baseline, 9.4% of the participants were rated as having depressed mood. The mean individual strength change over 3 years was - 6.9% (standard deviation 14.0). Steep strength decline was determined as losing > or = 14% (lowest quartile). The proportions of those with steep strength decline in the groups based on combined distributions of BMI and depressed mood were: underweight/ depressed (n = 22) 41%, underweight/not depressed (n = 200) 28%, normal weight/depressed (n = 127) 30%, normal weight/not depressed (n = 1181) 25%, overweight/depressed (n = 55) 31%, overweight/not depressed (n = 675, referent) 21%. After adjusting for baseline strength, age, height, sociodemographic variables and diseases, the odds ratio for steep strength decline was more than four times greater among those who were depressed and underweight, and twice as great among people who were depressed and normal weight compared with those who were nondepressed and overweight. The risks of nondepressed under- and normal weight people and depressed overweight people did not differ from the reference group. CONCLUSIONS: Depressed mood was associated with increased risk of steep strength decline, in particular in older men with low body weight. Low body weight in combination with depressed mood may be an indicator of frailty or severe disease status that leads to accelerated strength loss and disability.     

Suicidal ideation and suicide attempts among human immunodeficiency virus-infected adults: differences in risk factors and their implications

Many studies have investigated risk factors for suicidal ideation and suicide attempt; however, most have failed to show differences in risk factors between suicidal ideation and suicide attempt among the human immunodeficiency virus (HIV)-infected population. This study was designed to identify differences in risk factors between suicidal ideation and suicide attempts among HIV-infected adults in Seoul. A face-to-face survey of 457 HIV-infected adults was conducted by the Seoul Metropolitan Government in 2013. Multivariate logistic regression analysis was used to identify factors associated with suicidal ideation and suicide attempt. Among 422 participants, 44% had suicidal ideation, and 11% had suicide attempts. The independent risk factors for suicidal ideation were young and middle age, living with someone, history of AIDS-defining opportunistic disease, history of treatment for depression, lower social support, and psychological status. Beneficiaries of National Medical Aid, economic barriers to treatment, history of treatment for depression, and lower psychological status were independently associated with suicide attempts. Patients with HIV in Korea were treated without cost in some centers. Thus, experiencing an economic barrier to treatment might be due in part to ignorance of HIV care policies. Our findings indicate that suicide attempts are associated with socioeconomic factors and information inequality regarding medical care. In conclusion, suicidal ideation closely associated with the psychosocial factors, whereas suicide attempt demonstrates a stronger association with socioeconomic factors. Suicide prevention measures should be implemented to provide information to help HIV-infected patients.     

Depression: treating the patient with comorbid cardiac disease

Depressed patients develop symptomatic and fatal ischemic heart disease at a higher rate than nondepressed patients, even after studies are controlled for known cardiovascular risk factors. Changes in sympathetic and parasympathetic tone appear to make depressed patients more vulnerable to ventricular fibrillation. Tricyclic antidepressants share the electrophysiologic profile of type 1A antiarrhythmic compounds and therefore may carry a risk of increased mortality when given to patients with ischemic heart disease. Serotonin reuptake inhibitors have shown no antiarrhythmic effect in depressed patients with serious cardiovascular disease, but studies to date have been small and short-term.     

Religion, risk, and medical decision making at the end of life

OBJECTIVE: The purpose of this study is to present empirical evidence about whether religious patients are more or less willing to undergo the risks associated with potentially life-sustaining treatment. METHODS: At least every 4 months 226 older community-dwelling persons with advanced cancer, congestive heart failure, or chronic obstructive pulmonary disease were asked questions about several dimensions of religiousness and about their willingness to accept potentially life-sustaining treatment. RESULTS: Results were mixed but persons who said that during their illness they grew closer to God (odds ratio [OR] = 1.79; 95% confidence intervals [CI] = 1.15, 2.78) or those grew spiritually (OR = 1.61; 95% CI = 1.03, 2.52) were more willing to accept risk associated with potentially life-sustaining treatment than were persons who did not report such growth. DISCUSSION: Not all dimensions of religiousness have the same association with willingness to undergo potentially life-sustaining treatment. Seriously ill older, religious patients are not especially predisposed to avoid risk and resist treatment.     

Depressive disorder as a predictor of physical disability in old age

OBJECTIVES: To determine whether the occurrence of depression predicts physical disability in older people. DESIGN: A longitudinal epidemiological study with a follow-up of 5 years. SETTING: A comparison between depressed and nondepressed participants. PARTICIPANTS: The series consisted of the persons who participated in the longitudinal epidemiological study on depression in old age performed in Ahtari, Finland. The first round of interviews and examinations was performed in 1984/1985 and the second round in 1989/1990. The study series (N = 786) was composed of persons functionally independent in activities of daily living (ADLs) during the first round and alive and participating in both rounds. MEASUREMENTS: Depression was determined according to DSM-III criteria. Physical functional abilities were measured with self-assessments of ability to manage ADLs. RESULTS: In bivariate analyses, depression at the baseline did not predict lowering of functional abilities during follow-up, but the occurrence of depression with a long-term or relapsing course during follow-up and the onset of depression during follow-up in persons not depressed at the baseline predicted lowering of functional abilities during follow-up. The logistic regression analyses showed the presence of the following variables measured during the first round--older age, low basic education, poor self-perceived health, and occurrence of a physical disease--and the onset of the following diseases during follow-up--any physical disease, neurological disease, cerebrovascular disease, or depressive symptoms (in persons nondepressed at the baseline)--predicted lowered functional abilities after a follow-up of 5 years. CONCLUSION: Depression that developed during the follow-up in previously nondepressed persons was associated with an increased risk for lowering of functional abilities, even when controlling for age, sociodemographic factors, physical diseases, and baseline disabilities. Depressed older people are at high risk for physical disability, and an individually planned program to maintain their functional abilities by training in ADLs and instrumental activities of daily living (IADLs) and physical exercise should be included in their treatment.
