Change in disability follows inpatient treatment for late life depression

Resilience does not mediate the association between adverse childhood experiences and later life depression. Findings from the Irish Longitudinal Study on Ageing (TILDA)

BACKGROUND

Resilience has been found to moderate the association between childhood trauma and later depression. We examined whether resilience mediates the association between Adverse Childhood Experiences (ACEs) and later life depression among older adults.

METHODS

Data were from The Irish Longitudinal Study on Ageing (TILDA), a prospective study of 8,500 community-dwelling adults aged ≥ 50 years. Negative binomial regressions were used to examine the relationships between ACEs, resilience, and depression and path analysis was conducted to test the potential mediating effect of resilience on the association between ACEs and depressive symptoms.

RESULTS

Mean CES-D8 depression score was 3.3 from a maximum of 24. The average resilience score from a maximum of 15 was 8.9. 26.0% of participants had experienced at least one ACE before the age of 18. A history of ACEs was associated with increased depressive symptomology. The strongest association was between physical abuse and depressive symptoms followed by sexual abuse, parental drug or alcohol use, and childhood poverty. Our path analyses showed that there was no evidence that resilience mediated the association between ACEs and depressive symptoms among this cohort.

LIMITATIONS

Information on ACEs was collected retrospectively. The resilience measure depended on experience of stressful life events in the last five years and therefore some participants were excluded.

CONCLUSIONS

ACEs were associated with an increased likelihood of late-life depressive symptoms. Higher resilience was associated with decreased likelihood of late-life depressive symptoms. A history of ACEs is associated with lower resilience. The association between ACEs and late-life depressive symptoms is not mediated by resilience.

What is the prevalence of untreated depression and death ideation in older people? Data from the Irish Longitudinal Study on Aging

ABSTRACTObjective:Late life depression (LLD) confers significant morbidity and mortality but is well recognized that it often goes undetected or untreated. The objective of this study is to quantify the burden of untreated depression and death ideation (DI) at a population level.

DESIGN

Cross-sectional study ascertaining the prevalence of, and factors associated with, untreated depression and DI.

SETTING

This study, embedded within the Irish Longitudinal Study on Ageing, involves over 7,000 community-dwelling people aged ≥50 years.

MEASUREMENTS

Depression was defined as Centre for Epidemiological Studies Depression scale ≥16 indicating current clinically relevant depressive symptoms or Composite International Diagnostic Interview indicative of major depressive episode within the last year. Participants not prescribed antidepressants/antipsychotics were defined as untreated. To define DI, participants were asked "In the last month, have you felt like you would rather be dead?"

RESULTS

In total, 12% (839/7,055) met criteria for depression with 29% (241/839) on pharmacological therapy. Those with untreated depression were less likely to endorse symptoms of persistent low mood or worthlessness, but there was no difference in age or general practitioner (GP) visits compared to those on treatment. Over 3% (223/7,055) of participants had DI and less than one-third had visited their GP within the last year.

CONCLUSIONS

This study demonstrates that two-thirds of depressed older people are not prescribed antidepressant/antipsychotic therapy. It is important to raise awareness of depression among older people and healthcare professionals, with particular focus on the fact that LLD is not an inevitable consequence of ageing and effective treatment is available.

A Systematic Review of the Measurement of Function in Late-Life Depression

Recovery of everyday premorbid function is a primary goal in the treatment of depression. Measurement of function is an important part of achieving this goal. A multitude of scales have been used to measure function in depression, reflecting the complex, multifaceted nature of functioning. Currently, however, there are no evidence-based guidelines to assist the researcher or clinician in deciding which instruments are best suited to measure function in late-life depression (LLD). Thus, the aims of this study are to 1) systematically review and identify the instrumental activities of daily living and social functioning assessment instruments used in the LLD literature; 2) identify and appraise the measurement properties of these instruments; and 3) suggest factors for LLD researchers and clinicians to consider when selecting functional assessment instruments and make pertinent recommendations. We performed a systematic review of MEDLINE and CINAHL to identify studies that i) incorporated subjects aged 60 years and older with a depressive disorder, and ii) measured instrumental activities of daily living and/or social functioning. Our search yielded 21 functional assessment instruments. Only two of these instruments, the 36-Item Short Form Survey and the Performance Assessment of Self-Care Skills, have formal validation data in LLD. Four additional instruments, although not formally validated, have relevant data regarding their measurement properties. The primary finding of this study is that very few functional assessment instruments have been validated in LLD, and the available measurement property data are mixed; there is a need for further instrument validation in late-life depression. With this caveat in mind, we provide evidence-based suggestions for researchers and clinicians assessing functioning in LLD patients.

A longitudinal study of depression in old age II: depression and physical disability

Objectives: As part of an outcome study of depression in older people, the relationship between physical disability and depression was explored at baseline and longitudinally. The aims were to identify whether illness in specific body systems or physical disability was associated with a poorer outcome of depression.

Method: Subjects over 65 with depression referred to an old age psychiatry service were recruited. Depression was diagnosed according to ICD-10 criteria. An in-depth initial assessment obtained data concerning depression severity and illness in specific body systems as well as disability levels. Objective and subjective ratings of health status were also made. Subjects were followed up at three, six, 12, 18, and 24 months. Ongoing assessments were made of depressive symptomatology and of physical status.

Results: Subjects with higher disability levels had more severe depression at baseline. There was no relationship between illness in specific body systems and depression severity. At follow up assessments, those with higher disability scores had poorer outcomes as recorded by depression rating scales and by reviewing the longitudinal course of depression in terms of proportions remaining well, suffering relapses or remaining depressed.

Conclusions: There is an ongoing relationship between depression and disability. Older people with greater physical disability have a poorer outcome of depression. Service providers should be aware of this relationship and respond rapidly and assertively to depression in older people with disability. There should be a lower threshold for initiating treatment in this population.

A Time-Series Study of Depression Using Cognitive-Behavioral Techniques Subsequent to Short-Term Psychodynamic Psychotherapy

This study examined the sequential use of two distinct treatment modalities in the care of a client with depression and comorbid anxiety. The client was initially treated with 16 sessions of short-term psychodynamic psychotherapy (STPP) followed by seven sessions of cognitive-behavioral therapy (CBT). Simulation modeling analysis was used to assess the symptom changes across both treatment phases. Symptoms tracked included level of self-esteem, degree of sadness, and overall distress. Results indicated that the client did not experience any significant changes in response to STPP, but did experience a reduction in distress and sadness, and an increase in self-esteem subsequent to CBT. This study highlights the importance of clinical flexibility in cases in which a particular treatment modality may not be effective. Complicating factors and implications are also discussed.

Depressive symptoms and impaired physical function after acute lung injury: a 2-year longitudinal study

RATIONALE

Survivors of acute lung injury (ALI) frequently have substantial depressive symptoms and physical impairment, but the longitudinal epidemiology of these conditions remains unclear.

OBJECTIVES

To evaluate the 2-year incidence and duration of depressive symptoms and physical impairment after ALI, as well as risk factors for these conditions.

METHODS

This prospective, longitudinal cohort study recruited patients from 13 intensive care units (ICUs) in four hospitals, with follow-up 3, 6, 12, and 24 months after ALI. The outcomes were Hospital Anxiety and Depression Scale depression score greater than or equal to 8 ("depressive symptoms") in patients without a history of depression before ALI, and two or more dependencies in instrumental activities of daily living ("impaired physical function") in patients without baseline impairment.

MEASUREMENTS AND MAIN RESULTS

During 2-year follow-up of 186 ALI survivors, the cumulative incidences of depressive symptoms and impaired physical function were 40 and 66%, respectively, with greatest incidence by 3-month follow-up; modal durations were greater than 21 months for each outcome. Risk factors for incident depressive symptoms were education 12 years or less, baseline disability or unemployment, higher baseline medical comorbidity, and lower blood glucose in the ICU. Risk factors for incident impaired physical function were longer ICU stay and prior depressive symptoms.

CONCLUSIONS

Incident depressive symptoms and impaired physical function are common and long-lasting during the first 2 years after ALI. Interventions targeting potentially modifiable risk factors (e.g., substantial depressive symptoms in early recovery) should be evaluated to improve ALI survivors' long-term outcomes.

Evaluation of quality of life in adults with chronic health conditions: the role of depressive symptoms

OBJECTIVE: The negative impact of depressive symptoms on quality of life has been the focus of increasing attention, yet this relation remains unstudied in samples from developing countries. The objective of this study was to determine whether the occurrence of depressive symptoms is associated with impaired quality of life and whether this association remains significant after adjustment for some variables. METHOD: A convenience sample was selected and the measures used were the WHOQOL-100, to assess quality of life, the Beck Depression Inventory, to screen for depressive symptoms, and the Economic Classification Criterion - Brazil, to evaluate socioeconomic status. RESULTS: One hundred nineteen healthy adults (community) and 122 adult patients (tertiary hospital) from Brazil were assessed. Depressive symptoms were negatively correlated with all the domains of quality of life, even after statistical control for age, socioeconomic status, and presence of chronic health conditions. Socioeconomic status was positively correlated with the social relationships and environmental domains of quality of life. CONCLUSION: Our findings indicate that depressive symptoms and socioeconomic status are important elements affecting the relationship between chronic health conditions and quality of life in Brazil.

The relationship between depressive symptoms and walking among Hispanic older adults: a longitudinal, cross-lagged panel analysis

OBJECTIVES

This study examines the relationship between depressive symptoms and walking behavior across 30 months in a prospective study of 217 community-dwelling, Hispanic older adults in Miami, Florida (ages 70-100 years).

METHOD

Analyses examine the direction of the relationship between depressive symptoms and physical activity (i.e., walking) over time, as well as test for a potential bi-directional or reciprocal relationship between these two variables.

RESULTS

Structural equation modeling (SEM) with a cross-lagged panel design revealed that walking was unrelated to subsequent depressive symptoms. However, depressive symptoms were related to subsequent walking behavior at every time-point, such that higher levels of depressive symptoms were predictive of less walking in the future. Older adults who had clinically-relevant depressive symptoms at the initial assessment had 1.34 times the risk of not walking 30 months later, compared to older adults without clinically-relevant depressive symptoms.

CONCLUSION

Results support the need for primary care providers to evaluate and address depressive symptoms among older adults, as a means of reducing sedentary behavior and potentially improving health. Further research on the prevention and management of depressive symptoms and sedentary behavior is needed, given the morbidity related to both of these health risks, particularly for minority and low-socio-economic status (SES) older adults.

Trajectories of mobility and IADL function in older patients diagnosed with major depression

OBJECTIVE

Research has shown an association between depression and functional limitations in older adults. Our aim was to explore the latent traits of trajectories of limitations in mobility and instrumental activities of daily living (IADL) tasks in a sample of older adults diagnosed with major depression.

METHODS

Participants were 248 patients enrolled in a naturalistic depression treatment study. Mobility/IADL tasks included walking one-fourth mile, going up/down stairs, getting around the neighborhood, shopping, handling money, taking care of children, cleaning house, preparing meals and doing yardwork/gardening. Latent class trajectory analysis was used to identify classes of mobility/IADL function over a 4-year period. Class membership was then used to predict functional status over time.

RESULTS

Using time as the only predictor, three latent class trajectories were identified: (1) Patients with few mobility/IADL limitations (42%), (2) Patients with considerable mobility/IADL limitations (37%) and (3) Patients with basically no limitations (21%). The classes differed primarily in their initial functional status, with some immediate improvement followed by no further change for patients in Classes 1 and 2 and a stable course for patients in Class 3. In a repeated measures mixed model controlling for potential confounders, class was a significant predictor of functional status. The effect of baseline depression score, cognitive status, self-perceived health and sex on mobility/IADL score differed by class.

CONCLUSIONS

These findings show systematic variability in functional status over time among older patients with major depression, indicating that a single trajectory may not reflect the pattern for all patients.

Pattern of brain atrophy in elderly patients with depression revealed by voxel-based morphometry

In this study, we explored to what extent brain abnormalities can be identified in specific brain structures of patients suffering from late onset depression. We examined the structural difference in regional gray and white matter volume between 14 community-dwelling patients suffering from geriatric depression and 20 age-matched non-depressed normal subjects by voxel-based morphometry (VBM) based on magnetic resonance imaging. All subjects also underwent an extensive neuropsychological assessment. Compared with control subjects, patients with depression were impaired in measures of verbal and visual memory, construction, executive ability, and information-processing speed. VBM of gray matter revealed a significant decrease of volume in the right rostral hippocampus, in the right amygdala and in the medial orbito-frontal cortex (gyrus rectus) bilaterally. In the correlation analysis of gray matter volume with the score of the geriatric depression scale, we observed a negative correlation with the medial orbito-frontal cortex (gyrus rectus) bilaterally. There were no differences in white matter volumes between patients with depression and healthy control subjects. The most important limitation of this study was sample size. A larger sample size may have improved detection of changes not reaching significance. Furthermore, our results may not be generalizable across depression severity or to hospitalized patients. The findings are consistent with our hypothesis that depression in the elderly is associated with local gray matter dysfunction.

COPD education and cognitive behavioral therapy group treatment for clinically significant symptoms of depression and anxiety in COPD patients: a randomized controlled trial

BACKGROUND

Chronic obstructive pulmonary disease (COPD) affects 14 to 20 million Americans and is associated with increased prevalence of affective disorders, contributing significantly to disability. This study compared cognitive behavioral therapy (CBT) group treatment for anxiety and depression with COPD education for COPD patients with moderate-to-severe anxiety and/or depressive symptoms.

METHOD

A randomized controlled trial (RCT) was conducted between 11 July 2002 and 30 April 2005 at the Michael E. DeBakey VA Medical Center, Houston, TX. Participants were 238 patients treated for COPD the year before, with forced expiratory value in 1 second (FEV)1/forced vital capacity (FVC)<70% and FEV1<70% predicted, and symptoms of moderate anxiety and/or moderate depression, who were being treated by a primary care provider or pulmonologist. Participants attended eight sessions of CBT or COPD education. Assessments were at baseline, at 4 and 8 weeks, and 4, 8 and 12 months. Primary outcomes were disease-specific and generic quality of life (QoL) [Chronic Respiratory Questionnaire (CRQ) and Medical Outcomes Survey Short Form-36 (SF-36) respectively]. Secondary outcomes were anxiety [Beck Anxiety Inventory (BAI)], depressive symptoms [Beck Depression Inventory-II (BDI-II)], 6-minute walk distance (6MWD) and use of health services.

RESULTS

Both treatments significantly improved QoL, anxiety and depression (p<0.005) over 8 weeks; the rate of change did not differ between groups. Improvements were maintained with no significant change during follow-up. Ratios of post- to pretreatment use of health services were equal to 1 for both groups.

CONCLUSIONS

CBT group treatment and COPD education can achieve sustainable improvements in QoL for COPD patients experiencing moderate-to-severe symptoms of depression or anxiety.

Health-related quality of life and the practice of electroconvulsive therapy

In the past several decades, health-related quality of life (HRQL) measures have become increasingly important as a type of patient-reported outcome documenting the subjective psychosocial burden associated with chronic illness. This article provides an introduction to HRQL, summarizes the measurement of HRQL in major depression and bipolar disorder, and reviews electroconvulsive therapy (ECT) studies that have measured HRQL. Health-related quality-of-life definitions and instruments vary widely but have nonetheless proven useful for evaluating the effects of disease and its treatment. Psychiatric disorders profoundly affect HRQL and, in many cases, exceed or contribute to the disease burden imposed by serious physical illness. An emerging literature demonstrates the importance of ECT in restoring function and HRQL in depressed patients. To keep pace as medicine is transformed along the dimensions outlined by the Institute of Medicine's Quality Chasm framework, ECT research must provide evidence supporting its safety and effectiveness and also that the treatment is patient-centered. A research agenda to demonstrate the subjective benefits of ECT must be mirrored by a practice of ECT that is increasingly customized to patient needs and values.

Health-related quality of life following ECT in a large community sample

BACKGROUND

While electroconvulsive therapy (ECT) is a potent antidepressant, little is known about its long-term effects on health-related quality of life (HRQOL).

METHODS

Using a naturalistic, observational design, 283 depressed patients, who received ECT at 7 hospitals in the New York City area, were assessed for HRQOL with the Medical Outcomes Study Short Form - 36 (SF-36) at baseline, several days after ECT, and 24 weeks later. Depression severity was assessed with the Hamilton Rating Scale for Depression, and a neuropsychological battery was also administered.

RESULTS

Baseline SF-36 scores were very low, indicating poor HRQOL. These scores were improved at postECT and at the 24-week follow-up. Unexpectedly, the degree of retrograde amnesia for autobiographical information was associated with better HRQOL in the immediate postECT period, but not at 24-week follow-up. In contrast, improvement in global cognitive status was associated with superior HRQOL at the 24-week time point.

LIMITATIONS

This study was limited by the lack of a non-ECT comparison group, and the naturalistic design of treatment.

CONCLUSIONS

ECT is associated with improved HRQOL in the short- and long-term, with the enhancements largely explained by improvements in depressive symptoms. The acute cognitive effects of ECT may also influence HRQOL assessment, and evaluations removed in time from the treatment may have greater validity.

Prevalence and Correlates of Functional Disability in Multiethnic Elderly Singaporeans

OBJECTIVES

To make comparative estimates of prevalence of late-life functional disability, examine sociodemographic and health correlates, investigate sex and ethnic differences, and estimate population attributable risk of modifiable risk factors.

DESIGN

Population-based survey.

SETTING

Multiethnic population of Singapore (3 million residents).

PARTICIPANTS

Noninstitutionalized Chinese, Malay, and Indian people aged 60 and older (N=1,079)

MEASUREMENTS

Functional disability was defined as needing help in at least one basic activity of daily living (ADL) task in the 10 items of the Barthel Index. Five basic ADLs (eating, bathing, dressing, transferring, toileting) were used to compare prevalence with those reported from other national surveys and with reported past prevalence within the country.

RESULTS

The prevalence of disability in at least one of five ADL items (6.6% in those aged > or = 65) appeared lower than elsewhere, including China, but higher than reported past prevalence within the country. Functional disability on at least one of the 10 ADL items was independently associated with female sex, Indian ethnicity, older age, poor self-rated health, specific chronic diseases, cognitive impairment, sensory impairment, and living with others. The population attributable risks for leading modifiable factors were arthritis (12%) and cognitive impairment (14%).

CONCLUSION

Lower prevalence of functional disability accompanies rapid aging and health transition in Singapore than in other countries but higher prevalence than reported past prevalence within the country. Associations with sociodemographic and health-related factors were consistent with Western studies, including unexplained sex and ethnic differences.

A 3-D model of health decline: disease, disability, and depression among Black and White older adults

Much of the research on health decline in older adulthood has specified a single causal direction between two health domains, often measured at the same time point, making it difficult to disentangle the mechanisms of health decline over time. Using three waves of data over seven years from older residents of North Carolina, a 3-D model is used to examine the temporal ordering of general health decline and the pathways of influence across three health domains (disease, disability, and depression). In addition, we test whether the 3-D model of health decline is similar for Black and White older adults. Results indicate that both prevalent and incident disease lead to increases in depression and that prevalent disease leads to greater disability three years later. Depression, in turn, leads to disease, identifying a cycle of health decline that is, for the most part, similar for Black and White older adults. The effect of widowhood is more deleterious to the health of Black older adults than for their White counterparts.

Depression in the elderly: new concepts and therapeutic approaches

Depression is one of the leading causes of suffering in the elderly, but it is often under-diagnosed and under-treated, partly due to the false belief that depression is a common aspect of aging. Depression in the elderly is frequently comorbid with medical illnesses, may often be expressed by somatic complaints, and may be a risk factor for other diseases such as dementia and coronary artery disease. Depression decreases the quality of life and increases disability and the risk of mortality, also due to suicide. Although several effective antidepressant drugs are available, with a favorable therapeutic index, non-pharmacological treatments, such as psychotherapy and exercise, should receive greater attention, since combination therapy is probably more effective.

Additive and interactive effects of comorbid physical and mental conditions on functional health

OBJECTIVE

To understand the role of cognitive impairment and depressive symptoms on functional outcomes of stroke and diabetes. Evaluation approaches to functional outcomes have rarely focused on the presence of specific comorbidities, particularly those involving mental health disorders.

METHODS

Data are from the AHEAD cohort of the Health and Retirement Study (HRS), a nationally representative panel of persons 70+ years of age in 1993. Analyses are limited to 5,646 self-respondents for whom functional outcome data are available in 1995. Additive and interactive multiple regression models are compared for each outcome and focal condition combination.

RESULTS

The additive model is sufficient for the majority of outcome and focal condition combinations. The interaction term is significant in 4 of 12 comparisons.

DISCUSSION

Stroke, diabetes, cognitive impairment, and depressive symptoms exhibit strong independent effects on physical functioning. Support for the hypothesis that cognitive impairment and depression exacerbate the impact of stroke and diabetes is more limited.

Depression, functional status, treatment for psychiatric problems, and the health-related practices of elderly HMO members

PURPOSE

To study relationships between depression, functional limitations, psychiatric treatment, and the health-related practices of elderly individuals.

DESIGN

Cross-sectional, observational study based on survey data (response rate = 90%) analyzed using multiple linear and logistic regression models.

SETTING

Kaiser Permanente Northwest, a large nonprofit HMO.

SUBJECTS

Medicare members (4615) aged 65-103 years who responded to a health status survey.

MEASURES

Depression, health and functional status, frequency of alcohol consumption, smoking status, advance medical directive completion, influenza or pneumonia vaccinations, mammograms, recent psychiatric treatment, and attempts to lose weight or increase exercise.

RESULTS

Self-reported depression was related to a greater risk of smoking (odds ratio [OR] = 1.54). Health-related functional limitations were related to fewer attempts to change health behaviors and less preventive service use (significant ORs ranged from 0.84 to 0.94). Minority group membership and Supplemental Security Income were negatively associated with better health practices and with completing advance medical directives (ORs 0.41 and 0.79, respectively). Falls in the prior year, more prescription medications, and psychiatric treatment were positively associated with better health practices (significant ORs ranged from 1.12 to 1.88).

CONCLUSIONS

Depression and smoking are associated among elderly individuals, as are psychiatric treatment and attempts to lose weight. Those with functional limitations, minority status, or Supplemental Security Income use fewer preventive services; the latter two groups are less likely to complete advance medical directives. Older adults with these characteristics might need assistance in improving health-related practices.

Smaller orbital frontal cortex volumes associated with functional disability in depressed elders

BACKGROUND

Depression is associated with significant functional impairment. Recent evidence has linked the orbital frontal cortex (OFC) with depression. We examined the relationship between OFC volumes in older subjects and impairment in the basic (BADL) and instrumental (IADL) activities of daily living.

METHODS

The sample consisted of 81 subjects aged 60 years or older; 41 were depressed subjects and 40 healthy control subjects. In a structured interview, subjects reported their medical history and ability to perform both BADL and IADL. Subjects then had a brain magnetic resonance imaging (MRI) scan; the OFC was manually traced bilaterally using neuroanatomical landmarks. Logistic regression was used to examine the effect of OFC volume on BADL and IADL while controlling for the effects of total brain volume, subject status, medical comorbidity, and demographic factors.

RESULTS

Smaller OFC volumes, along with greater cognitive impairment as measured by the Mini-Mental State Examination, were significantly associated with BADL impairment. Smaller OFC volumes and being depressed were significantly associated with IADL impairment.

CONCLUSIONS

Smaller OFC volumes are independently associated with functional impairment, supporting its role in depression. Further studies are needed to determine how smaller OFC volumes are related to other MRI abnormalities associated with depression and functional impairment.

Prevention of brain aging and dementia

The brain is subjected to multiple factors that result in damage to its cellular constituents, the neuron and supporting cells, and the neural networks that form the bases of cognitive ability. Like other systems, the brain has remarkable capacity to repair that damage and to adapt or compensate for the loss of neurons and the disruption of the neural architecture. Brain aging and dementia can be conceptualized as a balance between neuronal injury and repair. This balance can be affected not only by genetic and age-related factors but also by multiple environmental factors. The latter includes many factors, including education, nutrition, exercise, socialization, and stress. As individuals, we have the potential to modify these factors through lifestyle choices. Advances in neuroscience have led to the development of pharmacologic agents that can ameliorate the effects of even genetic (e.g., statins and antihypertensive agents) and age-related (e.g., antioxidants and estrogen replacement) factors. By altering the balance between neuronal injury and repair, we can delay the expression and progression of the neurodegenerative processes of brain aging, AD, and related dementias.

Association between medical comorbidity and treatment outcomes in late-life depression

OBJECTIVES

Previous studies have demonstrated an association between major depression and physical disability in late life. The objectives of this study were to examine the relationship between specific medical illnesses and the outcomes of treatment for late-life depression.

DESIGN

The study was a longitudinal assessment of medical illness, depression, and disability. Patients were assessed during an initial inpatient psychiatric hospitalization and 3 months postdischarge.

SETTING

All patients were initially evaluated after admission to one of 71 inpatient psychiatric treatment facilities.

PARTICIPANTS

A sample of 671 older patients who received inpatient treatment for depression was evaluated at entry into the hospital and 3 months after discharge.

MEASUREMENTS

Depressive symptoms were measured using the Geriatric Depression Scale. Disability was measured using the instrumental activities of daily living scale and the Medical Outcomes Study 36-item short form. Medical illness was assessed using the medical illness checklist.

RESULTS

As previously reported, physical disability and the total number of medical illnesses were significantly related to change in depressive symptoms. In this study, we find that arthritis, circulatory problems, a speech disorder, or a skin problem, but not other general medical conditions, were related to a worse outcome with respect to depression symptoms. The effect of these problems was statistically and clinically significant. After controlling for pretreatment disability, arthritis and skin problems continued to predict a worse outcome. However, the apparent effect of each of these conditions was mediated by the residual disability after treatment.

CONCLUSION

The results of this study support the hypothesis that certain somatic disorders play a role in the treatment response of late-life depression and suggest that the effect of specific illnesses on depression may be mediated by the presence of functional disability.

The spectrum of quality-of-life impairments in recurrent geriatric depression

BACKGROUND

Although recurrent major depression in elderly individuals is a disabling condition, only a few studies have systematically examined the magnitude and specificity of quality-of-life (QOL) impairments in such patients in comparison with matched controls or the elderly population.

METHODS

We examined the variations in QOL scores of 100 elderly (age range 60-88 years) patients with moderate to severe recurrent major depression and compared them with published elderly population norms. Disease-specific Quality of Life in Depression Scale (QLDS) and generic Medical Outcomes Short Form-36 Health Survey (SF-36) QOL ratings obtained at baseline were analyzed.

RESULTS

Compared with published elderly population norms, depressed subjects showed significant QOL impairments in five of eight baseline SF-36 items (p <.01). Women rated their QOL as worse than men on physical functioning and role physical (p <.01) and showed similar trends on all other QOL items. Compared with younger subjects, subjects aged older than 70 years reported lower QOL on the summary physical component (p <.01) and a trend for higher QOL on the summary mental component (p <.05) of the SF-36. Depression symptom ratings were correlated with some QOL measures, but accounted for less than 10% of the variance.

CONCLUSIONS

Despite limitations, such as a cross-sectional design and indirect comparisons with norms generated from another study, our findings confirm the disabling nature of recurrent late-life depression and the importance of targeting both depressive symptoms and broader QOL outcomes in intervention trials.

Influence of smoking on the health status of spinal patients: the National Spine Network database

STUDY DESIGN

Multicenter, cross-sectional analysis of data from the National Spine Network.

OBJECTIVES

Investigate the association between the smoking status of spinal patients, duration and severity of symptoms, and their self-reported health status.

BACKGROUND

Although cigarette smoking was identified as a potential risk factor for lower back pain many years ago, more recent research is challenging this finding.

METHODS

The National Spine Network database contains information on the initial visit of spinal patients visiting physicians at 23 health care institutions in the United States. All patients for whom data were available regarding smoking status are included in this study (n = 25,455).

RESULTS

Data from a total of 25,455 patients (11,494 men and 13,961 women) were included in the study; 16.7% (n = 4249) were smokers. Smokers were younger than nonsmokers (44.2 vs. 48.7 years) and were more likely to report severe back symptoms (37 vs. 50%) and to report symptoms of depression (54 vs. 37%). Smokers of each gender scored 10-15 points lower than nonsmokers on each of the SF-36 subscales. These differences persisted when the absolute scores were compared with age- and sex-specific population norms and after adjustment for comorbid conditions, educational level, and depression. Similar results were obtained when the cohort was stratified by primary diagnosis or by surgical status. When postsurgical patients were grouped by time since surgery, those who were nonsmokers reported improved health status by time period; those who smoked did not.

CONCLUSIONS

Smokers and nonsmokers had had spinal symptoms for similar duration, but the smokers reported more severe symptoms, which were present for a greater proportion of time each day. Also, the smokers had lower physical and mental health status scores (based on the SF-36) than did nonsmokers.
