Depression IN THE ELDERLY

Developing a nomogram for predicting the depression of senior citizens living alone while focusing on perceived social support

BACKGROUND

Although the number of senior citizens living alone is increasing, only a few studies have identified factors related to the depression characteristics of senior citizens living alone by using epidemiological survey data that can represent a population group.

AIM

To evaluate prediction performance by building models for predicting the depression of senior citizens living alone that included subjective social isolation and perceived social support as well as personal characteristics such as age and drinking.

METHODS

This study analyzed 1558 senior citizens (695 males and 863 females) who were 60 years or older and completed an epidemiological survey representing the South Korean population. Depression, an outcome variable, was measured using the short form of the Korean version CES-D (short form of CES-D).

RESULTS

The prevalence of depression among the senior citizens living alone was 7.7%. The results of multiple logistic regression analysis showed that the experience of suicidal urge over the past year, subjective satisfaction with help from neighbors, subjective loneliness, age, and self-esteem were significantly related to the depression of senior citizens living alone (P < 0.05). The results of 10-fold cross validation showed that the area under the curve of the nomogram was 0.96, and the F1 score of it was 0.97.

CONCLUSION

It is necessary to strengthen the social network of senior citizens living alone with friends and neighbors based on the results of this study to protect them from depression.

Prevalence of Major Depressive Disorder and Correlates of Thoughts of Death, Suicidal Behaviour, and Death by Suicide in the Geriatric Population-A General Review of Literature

Background: There has been an increase in deaths by suicide in old age in the last decade. Depression and suicide in the elderly, 60 years and above, is a major global public health concern. Determining the prevalence of depression, and correlates of death by suicide in the geriatric population, is an important first step toward addressing this public health concern. This literature review aims to determine the prevalence of major depressive disorders and the correlates of death by suicide in the geriatric population. Methods: This general review of the literature was performed using relevant search terms to determine both the prevalence of depression and the correlates of death by suicide among the geriatric population. Databases such as MEDLINE, PsycINFO, CINAHL, and PubMed were searched. Relevant and current articles were extracted, reviewed, and analyzed. The elderly population was defined as individuals 60 years and above. Only full texts articles in English were reviewed. Findings: The prevalence estimates of major depressive disorder in the elderly ranged from 5.37 to 56%. Adults aged 60 years and older have a high risk of depression that exposes them to suicide. Moreover, elderly women are more likely to experience depression than elderly men, but successful suicide is more common in men. Depression and other mental health conditions (schizophrenia, anxiety disorders) and perceived stress were found to be predictors of suicide in the elderly. Other predictors included physical illnesses such as malignancies, financial constraints, cuckoldry, and sexual dysfunction, and also social factors like living alone triggers depressive symptoms and increases suicidal risk in the elderly. Hanging was found to be the most common method of death by suicide for both sexes. While elderly women preferred poisoning, elderly men in Western countries preferred firearms. Differences in gender, the aging process and social issues were also contributing factors to methods used for suicide. Conclusions: Depression and debilitating physical illnesses were identified as significant contributors to suicide risk in the elderly population, and emphasis should be placed on identifying these factors early and treating them. Recognizing and addressing factors that predict suicide in the elderly will help to improve the mental wellbeing of the elderly.

Preventing Suicide and Depression: A Training Program for Long-Term Care Staff

Approximately 5 percent of those sixty-five and older live in long-term care facilities (1.5 million). Neither suicide and depression among the elderly who reside in long-term care facilities nor prevention techniques are well-understood by staff. This article discusses the development of a curriculum designed to train long-term care staff in preventing suicide among the elderly and the results of a pilot test of a training program based on that curriculum. The participants ( N=43) significantly improved their scores from pre- to post-test on the knowledge, attitudes, and practices subtests. The knowledge areas in which staff performed the most poorly at pre-test were related to identifying appropriate primary and secondary interventions, the relationship between dementia and suicide, methods of self-destruction used by the elderly, and understanding of depression in the elderly. There was a significant relationship between pre-test and post-test scores on all subtests. Staff with higher levels of education had significantly higher pre- and post-test scores on the knowledge and attitudes subtests. More experienced staff had significantly higher post-test scores on the practices subtest. A large majority of the participants had highly positive attitudes toward the program and thought the program had been very useful or useful to them as caregivers. The study demonstrated the need for staff training related to suicide prevention in long-term care as well as the usefulness of even a brief training.

Decreases in dilated pupil size in depressed patients with age may reflect adrenergic changes

Some studies have suggested that noradrenergic activity may decrease with age in depressed patients. Pupil size is regulated by a balance between norepinephrine and acetylcholine. The present study compares pupil size in 10 unmedicated patients with unipolar depression (296. 3) and in 16 normal controls. Pupil size after dilation with tropicamide, a cholinergic antagonist, was inversely related to age in the patients (r=-0.87), but did not diminish with age in controls. The results suggest that pupil size may provide an index of diminished noradrenergic function with age in patients with major depression.

Risk for suicide and risk for violence: a case for separating the current violence diagnoses

PURPOSE

To identify accurate descriptive terms for risk for violence and risk for suicide and to provide operational definitions for these terms

METHODS

The Delphi technique, with two rounds, was used to differentiate the operational definitions that represent risk for suicide from those that represent risk for violence. The expert panel consisted of 23 healthcare professionals with a minimum of a master's degree. In addition to the expert panel, a control group (N = 11) participated to assess content validity.

FINDINGS

Thirty-six definitions were agreed upon for suicide, 39 for violence.

CONCLUSIONS

These definitions represent the basic distinctions between the two behavioral manifestations.

Electroconvulsive therapy and the elderly client

Although ECT has been the subject of controversy for decades, ECT has brought increased chances for recovery to many people suffering from severe depression. Crossfield (1988) states the evidence is overwhelming that treatment of some depressive clients with ECT is the best treatment available. Other researchers have found that ECT is equal to, and sometimes superior to, other therapies for major depressive disorders (Gomez & Gomez, 1993). Depression is a treatable condition about which nurses have a responsibility to educate clients and their families (Valente, 1991). If clients and their supportive families and friends are to understand rather than undermine treatment, education about ECT is essential (Valente, 1991). Well-meaning friends and family who are misinformed could strongly discourage ECT, so it is important that their myths about ECT be dispelled (Valente, 1991). Furthermore, if depression in an already at-risk elderly population is not recognized and treated, great suffering will continue to be endured and life-threatening situations may occur. Depression often is manifested differently in older persons than in younger ones. Nurses can improve the quality of care provided to these depressed elderly clients by allowing them to express their fears and anger (Gomez & Gomez, 1993). Furthermore, the nurse's attitude should be hopeful, positive and consistent with them. This action can help clients develop trust with the nurse and further their own quality care. Estimates are that 70% to 90% of individuals who suffer from severe depression and receive ECT do indeed recover (Valente, 1991). ECT should be undertaken only after the outlined treatment protocols have been considered and with the knowledge and understanding of the following statements issued by the United States Department of Health and Human Services in the 1993 Agency for Health Care Policy and Research (AHCPR). First, ECT has not been adequately tested in milder forms of depression. Because of this gap in the research, the efficacy of ECT across the spectrum of depressive symptomatology is unknown. Second, ECT is costly when it entails hospitalization. This factor has great meaning in the changing, increasingly cost-conscious, health care arena. Third, ECT has specific and significant side effects, e.g., short-term retrograde and anterograde amnesia. Not only are these side effects troublesome for inpatient recipients of ECT, but the side effects can be quite dangerous for persons receiving treatment on an outpatient basis. The potential for injury is grave for persons who have memory deficit. Given the present cost-conscious, cost-cutting atmosphere, an anticipated rise in the number of clients receiving ECT on an outpatient basis is a distinct possibility. Fourth, the risks of general anesthesia are present. Age is a well known risk factor for general anesthesia. Fifth, treatment with ECT still carries substantial social stigma for clients. In spite of the increasing acceptance of ECT as a treatment for depression in the elderly, many clients prefer to keep their receipt of treatment secret fearing social repercussions of open discussions with family and friends. Sixth, ECT can be contraindicated when certain other medical conditions are present. Persons suffering from severe cardiac or pulmonary disease are frequently disqualified for treatment due to the risk of receiving anesthesia. Last, people usually require a prophylactic treatment with antidepressant medication, even if a complete, acute phase response to ECT is attained (pp. 26-27).

Suicidal Thought and Self-Transcendence in Older Adults

1. The suicide rate for adults over 65 years of age is the highest rate for suicide in any age group, and the rate is projected to increase. 2. To address a clinical concern, such as suicide, clinicians and researchers must identify factors that are specific to each population at high risk. This study chose to examine self-transcendence, which is thought to be specific to older adults' success in meeting the multiple changes of later life. 3. Two questions that address self-transcendence are: "Who is most meaningful (important) to you now?" and "What is most meaningful (important) to you now?" If an older adult is unable to answer these questions, a suicide risk assessment should probably be done.
