Poststroke depression: prevalence, diagnosis, treatment, and disease progression.

Psychological distress often causes suffering in terminally ill patients and their families and poses challenges in diagnosis and treatment. Increased attention to diagnosis and treatment of depression can improve the coping mechanisms of patients and families. This paper reviews the clinical characteristics of normal grief and clinical depression and explains strategies for differential diagnosis. Although some literature discusses the psychological issues facing elderly patients and terminally ill patients with cancer, less is known about patients with end-stage pulmonary, cardiac, renal, and neurologic disease. Data on the effectiveness of interventions in terminally ill patients are lacking. Treatment recommendations in this paper represent extrapolations from existing literature and expert opinion. Diagnosing and treating depression in terminally ill patients involve unique challenges. Evidence of hopelessness, helplessness, worthlessness, guilt, and suicidal ideation are better indicators of depression in this context than neurovegetative symptoms. Although terminally ill patients often have suicidal thoughts, they are usually fleeting. Sustained suicidal ideation should prompt a comprehensive evaluation. Clinicians should have a low threshold for treating depression in terminally ill patients. Psychostimulants, because of their rapid onset of action, are useful agents and are generally well tolerated. Selective serotonin reuptake inhibitors and tricyclic antidepressants may also be used. Psychological interventions-including eliciting concerns and conveying the potential for connection, meaning, reconciliation, and closure in the dying process-can also facilitate coping.

Assessing and Managing Depression in the Terminally Ill Patient

Objectives: To develop nationally representative estimates of rates of diagnosis of depression; to determine rates and type of treatment received by those diagnosed with depression; and to ascertain socioeconomic differences and trends in treatment rates of depression, including the effect of supplemental insurance coverage, for elderly Medicare fee-for-service beneficiaries.



Design: Analysis of merged interview and Medicare claims data for multiple years from merged Medicare claims and interview data from the Medicare Current Beneficiary Survey (MCBS), a nationally representative survey of Medicare participants.



Setting: Community dwellers.



Participants: Twenty thousand nine hundred sixty-six community-dwelling respondents aged 65 and older in the MCBS cost and use files for 1992 through 1998.



Measurements: Diagnoses recorded in Medicare claims were used to identify individuals who received a diagnosis of depression from a healthcare provider; pharmacy and claims data were used to identify receipt of antidepressants and psychotherapy by those diagnosed.



Results: The rate of depression diagnosis more than doubled, reaching 5.8% in 1998. Overall, about two-thirds of those diagnosed received treatment in each year; but those aged 75 and older, those of “Hispanic or other” ethnicity, and those without additional coverage to supplement Medicare were significantly less likely to receive treatment, controlling for other characteristics. If treated, members of these disadvantaged subgroups were less likely to receive psychotherapy.



Conclusion: Although depression has been thought until recent years to be underrecognized in the elderly, rates of diagnosis increased dramatically in the 1990s, with concomitant increases in treatment. Nevertheless, significant disparities by age, ethnicity, and supplemental insurance coverage persist in treatment of those diagnosed. Because depression is a major source of potentially treatable morbidity in older people, increased efforts are needed to ensure access to appropriate treatment across all subgroups of older people and to remove economic barriers to treatment.

Diagnosis and treatment of depression in the elderly medicare population: predictors, disparities, and trends.

Background: Biases in adverse effect reporting in randomized controlled trials (RCTs) [e.g. due to investigator expectations or assessment quality] can be quantified by studying the rates of adverse events reported in the placebo arms of such trials. Objective: We compared the rates of adverse effects reported in the placebo arms of tricyclic antidepressant (TCA) trials and placebo arms of selective serotonin reuptake inhibitor (SSRI) trials. Methods: We conducted a literature search for RCTs across PUBMED, Scopus and the Cochrane Central Register of Controlled Trials (CENTRAL). Only studies allowing adverse effect analysis were included. Publication year ranged from 1981 to 2007. Results: Our systematic review and meta-analysis included 143 placebo-controlled RCTs and data from 12 742 patients. Only 21% of studies used structured and systematic adverse effect ascertainment strategies. The way in which trials recorded adverse events influenced the rate of adverse effects substantially. Systematic assessment led to higher rates than less systematic assessment. Far more adverse effects were reported in TCA-placebo groups compared with SSRI-placebo groups, e.g. dry mouth (odds ratio [OR] = 3.5; 95% CI 2.9, 4.2); drowsiness (OR = 2.7; 95% CI 2.2, 3.4); constipation (OR = 2.7; 95% CI 2.1,3.6); sexual problems (OR =2.3; 95% CI 1.5,3.5). Regression analyses controlling for various influencing factors confirmed the results. Conclusion: Adverse effect profiles reported in clinical trials are strongly influenced by expectations from investigators and patients. This difference cannot be attributed to ascertainment methods. Adverse effect patterns of the drug group are closely related to adverse effects of the placebo group. These results question the validity of the assumption that adverse effects in placebo groups reflect the ‘drug-unspecific effects’.

Differences in adverse effect reporting in placebo groups in SSRI and tricyclic antidepressant trials: a systematic review and meta-analysis.

Background
There is an increased risk of depression in people with a physical illness. Depression is associated with reduced treatment adherence, poor prognosis, increased disability and higher mortality in many physical illnesses. Antidepressants are effective in the treatment of depression in physically healthy populations, but there is less clarity regarding their use in physically ill patients. This review updates Gill’s Cochrane review (2000), which found that antidepressants were effective for depression in physical illness. Since Gill there have been a number of larger trials assessing the efficacy of antidepressants in this context.

Objectives
To determine the efficacy of antidepressants in the treatment of depression in patients with a physical illness.

Search methods
Electronic searches of the Cochrane Depression, Anxiety and Neurosis Review Group (CCDAN) trial registers were conducted together with supplementary searches of The Cochrane Central Register of Controlled Trials (CENTRAL) and the standard bibliographic databases, MEDLINE, EMBASE and PsycINFO. Reference lists of included studies were scanned and trials registers were searched to identify additional unpublished data. Last searches were run in December 2009.

Selection criteria
Randomised controlled trials comparing the efficacy of antidepressants and placebo in the treatment of depression in adults with a physical illness. Depression included diagnoses of Major Depression, Adjustment Disorder and Dysthymia based on standardised criteria.

Data collection and analysis
The primary outcome was efficacy 6-8 weeks after randomisation. Data were also extracted at three additional time-points (4-5 weeks, 9-18 weeks, >18 weeks). Acceptability and tolerability were assessed by comparing the number of drop-outs and adverse events. Odds ratios with 95% confidence intervals were calculated for dichotomous data (response to treatment). Standardised mean differences with 95% CI were calculated for continuous data (mean depression score). Data were pooled using a random effects model.

Main results
Fifty-one studies including 3603 participants were included in the review. Forty-four studies including 3372 participants contributed data towards the efficacy analyses. Pooled efficacy data for the primary outcome provided an OR of 2.33, CI 1.80-3.00, p<0.00001 (25 studies, 1674 patients) favouring antidepressants. Antidepressants were also more efficacious than placebo at the other time-points. At 6-8 weeks, fewer patients receiving placebo dropped out compared to patients treated with an antidepressant. Dry mouth and sexual dysfunction were more common in patients treated with an antidepressant.

Authors' conclusions
This review provides evidence that antidepressants are superior to placebo in treating depression in physical illness. However, it is likely that publication and reporting biases exaggerated the effect sizes obtained. Further research is required to determine the comparative efficacy and acceptability of particular antidepressants in this population.

Antidepressants for depression in physically ill people

To assess whether tricyclic antidepressants are useful in patients with a serious physical disorder who develop symptoms of major depression, 42 medically ill outpatients who met RDC criteria for endogenous major depression and had a Raskin depression score of at least 7 were studied The patients were randomly assigned to a 6-week trial of trimipramine or placebo under double-blind conditions In the placebo group, depressive symptoms improved when the physical disorder improved; in the trimipramine group, improvement was seen in the depressive symptoms even when there was no concomitant improvement in physical condition
