What should we do about undertreatment of late life psychiatric disorders in primary care?

Depressive Symptom Network Associated With Comorbid Anxiety in Late-Life Depression

Background: Depression and anxiety are the most common comorbid psychiatric disorders in the elderly. Psychiatrists have been reporting worsened depression symptoms and prognosis by comorbid anxiety symptoms. However, it is still unclear how anxiety affects the course of depression in the elderly. The aims of this study are (1) to identify the symptom network in late-life depression (LLD), and (2) to examine the role of anxiety in LLD with a network perspective. Methods: The study analyzed 776 community-based participants who were clinically diagnosed with depression and enrolled in Suwon Geriatric Mental Health Center. Network analysis was used to investigate the relationships between the symptoms of the Montgomery-Åsberg Depression Rating Scale (MADRS). The depression sample was divided into groups of low and high anxiety according to the Beck Anxiety Index. Propensity score matching (PSM) was used to minimize the effects of depression severity on the network. Network comparison test (NCT) were carried out to compare the global connectivity, global strength, and specific edge strength between the two subgroups. Results: Reported sadness, pessimistic thinking, and suicidal ideation are the core symptoms of LLD in terms of node strength. The MADRS sum score [mean (SD) 28.10 (9.19) vs 20.08 (7.11); P < .01] was much higher in the high anxiety group. The NCT before PSM showed the high anxiety group had significantly higher global strength (P < .01). However, the NCT after PSM did not reveal any statistical significance both in global structure (P = .46) and global strength (P = .26). A comparison between centrality indices showed a higher node strength of vegetative symptoms in the high anxiety group and this also remained after PSM. Conclusion: Based on the statistical analysis, anxiety worsens the severity of depression in the elderly. However, NCT after PSM revealed comorbid anxiety does not change the global structure and strength of the depression symptom network. Therefore, anxiety may affect LLD in a way of worsening the severity, rather than changing psychopathology. Additionally, the study revealed the centrality of vegetative symptoms was low in LLD but increased substantially in patients with comorbid anxiety.

Understanding older adults' medication decision making and behavior: A study on over-the-counter (OTC) anticholinergic medications

BACKGROUND

Older adults purchase and use over-the-counter (OTC) medications with potentially significant adverse effects. Some OTC medications, such as those with anticholinergic effects, are relatively contraindicated for use by older adults due to evidence of impaired cognition and other adverse effects.

OBJECTIVE

To inform the design of future OTC medication safety interventions for older adults, this study investigated consumers' decision making and behavior related to OTC medication purchasing and use, with a focus on OTC anticholinergic medications.

METHODS

The study had a cross-sectional design with multiple methods. A total of 84 adults participated in qualitative research interviews (n = 24), in-store shopper observations (n = 39), and laboratory-based simulated OTC shopping tasks (n = 21). Simulated shopping participants also rank-ordered eight factors on their importance for OTC decision making.

RESULTS

Findings revealed that many participants had concerns about medication adverse effects, generally, but were not aware of age-related risk associated with the use of anticholinergic medications. Analyses produced a map of the workflow of OTC-related behavior and decision making as well as related barriers such as difficulty locating medications or comparing them to an alternative. Participants reported effectiveness, adverse effects or health risks, and price as most important to their OTC medication purchase and use decisions. A persona analysis identified two types of consumers: the habit follower, who frequently purchased OTC medications and considered them safe; and the deliberator, who was more likely to weigh their options and consider alternatives to OTC medications.

CONCLUSION

A conceptual model of OTC medication purchase and use is presented. Drawing on study findings and behavioral theories, the model depicts dual processes for OTC medication decision making - habit-based and deliberation-based - as well as the antecedents and consequences of decision making. This model suggests several design directions for consumer-oriented interventions to promote OTC medication safety.

Clinical interventions for late-life anxious depression

Anxiety symptoms are frequently present in patients with late-life depression. The designation “anxious depression” has been used to describe major depressive disorder (MDD) accompanied by clinically significant but subsyndromal anxiety symptoms. MDD may also present comorbid with diagnosable anxiety disorders, although this presentation is less common in late life. Diagnosis of anxious depression in the elderly is complicated by several factors (eg, their tendency to experience and report psychiatric symptoms as somatic illness) and is associated with a more severe clinical presentation, increased risk for suicidal ideation, increased disability, and poorer prognosis. Standard pharmacotherapy for depression may be sufficient but for many patients must be modified or augmented. Psychosocial interventions may also be an important component in the treatment of these patients, although no specific psychosocial treatments have been developed for late-life anxious depression.

The application of the principles of geriatrics to the management of the older person with cancer

Is the patient going to die of cancer or with cancer? Is the patient going to suffer pain and disability due to cancer? Is the patient able to tolerate aggressive life-prolonging treatment? This paper tries to reply to the fundamentals of these questions by introducing the multidimensional assessment that evaluates areas where age-related changes are more likely. Chronologic age cannot be used to predict the degree of comorbidity and of functional deterioration of the single individual up to age 85 at least. Assessment of aging includes health, functional status, nutrition, cognition, socio-economic and emotion evaluations. This multidisciplinary assessment is referred to as comprehensive geriatric assessment (CGA). The risk of comorbid conditions increases with age and may result in underdiagnosis: in older patients, new symptoms may not be clearly recognized by the patient and may be dismissed by practitioners as manifestations of preexisting conditions. A meaningful assessment of comorbidity may be obtained with a comorbidity index. The Charlson scale and the Chronic Illness Rating Scale - Geriatric (CIRS-G), have enjoyed the widest acceptance. The Instrumental Activities of Daily Living (IADL) and the Activities of Daily Living (ADL) are the most sensitive assessment of function in older individuals. IADLs include shopping, managing finances, housekeeping, laundry, meal preparation, ability to use transportation and telephone and ability to take medications: in simple words, the IADLs are those skills a person needs to live independently. ADLs include feeding, grooming, transferring, toileting and are the skills necessary for basic living. Though a correlation exists among comorbidity, performance status, ADL and IADL, this correlation is not strong enough to be reflected in a single parameter. The Folstein Mini Mental Status (MMS), is the instrument of most frequent use to screen older individuals for dementia. The main problem with the MMS is lack of sensitivity to early stages of dementia. The Geriatric Depression Scale (GDS), a simple tool that can be completed by most patients at home, doubles the rate of detection of depression. The Mini Nutritional assessment is very sensitive to screen older persons for malnutrition. The risk of polypharmacy increases with age and partly results from the fact that older patients visit different practitioners. A CGA should also include evaluation of the so called Geriatric Syndromes like delirium, incontinence, osteoporosis, all of which represent a hallmark of frailty. The CGA may help the management of older individuals with cancer in at least three areas: detection of frailty, treatment of unsuspected conditions, removal of social barrier to treatment.
