Efficacy, safety, and tolerability of sertraline in patients with late-life depression and comorbid medical illness

OBJECTIVES: To report on the efficacy, safety, and tolerability of sertraline in the treatment of elderly depres-sed patients with and without comorbid medical illness. SETTING: Multicenter. DESIGN: Randomized, double-blind, placebo-controlled study. PARTICIPANTS: A total of 752 patients aged 60 and older with diagnosis of major depressive disorder according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis. MEASUREMENTS: Outcome measures included the 17-item Hamilton Depression Scale (HAMD); the Clinical Global Depression-Severity/Improvement (CGI-S/CGI-I); efficacy and safety/adverse event assessments; Quality of Life, Enjoyment, and Satisfaction Questionnaire; and the Medical Outcomes Study 36-Item Short-Form Health Status Survey. RESULTS: In the overall sample, sertraline was superior to placebo on all three primary outcome measures, HAMD, and overall clinical severity and change (CGI-S/CGI-I). Furthermore, therapeutic response to sertraline was comparable in those with or without medical comorbidity, and there were no treatment-by-comorbidity group interactions. Sertraline was also associated with a faster time to response than placebo in the comorbid group (P<.006). Sertraline-treated patients in the comorbid group had similar adverse events and discontinuations when compared to those in the noncomorbid group. CONCLUSION: Sertraline was efficacious in reducing depressive symptomatology, regardless of the presence of comorbid medical illness. Sertraline was safe and well tolerated by patients with or without medical illness.     

Discussion of depression in follow-up medical visits with older patients

OBJECTIVES: To determine the frequency of discussion about depression in follow-up medical visits of older patients, who initiates these discussions, the quality of responsiveness of physicians and patients in these discussions, and patient and physician characteristics that influence these discussions.
DESIGN: Convenience sample of 482 audiotaped follow-up visits.
SETTING: Three community-based practice sites.
PARTICIPANTS: Three hundred seventy-six community-dwelling older patients without dementia and 43 primary care physicians.
MEASUREMENTS: Audiotapes were analyzed using the Multi-Dimensional Interaction Analysis system to determine the content and process of medical conversations; patients completed Medical Outcomes Study 36-item Short Form Survey questionnaires immediately after the visit.
RESULTS: Depression was discussed in 7.3% of medical visits; physicians raised this topic in 41% of visits, patients raised it in 48% of visits, and accompanying persons raised it in 10% of visits. Visits were longer when the topic of depression was discussed. Depression was raised almost exclusively in the first 2.5 years of the patient–physician relationship. Physicians with some geriatric training were more likely to discuss depression, and these visits were shorter than visits to physicians without geriatric training.
CONCLUSION: Depression was raised infrequently in follow-up visits. The high prevalence of depression in older people and the associated mortality merit discussion of depression early and later in the patient–physician relationship. Although visits were longer when depression was discussed, physicians with some geriatric training were more likely to raise depression, and more time-efficient when they did so, than physicians without geriatric training.     

Natural history of symptoms of depression and anxiety during inpatient treatment on general medicine wards

Objective:To establish the frequency of criteria-based depression and anxiety in newly admitted medical inpatients and to determine the natural history of depressive and anxiety symptoms during hospitalization. Design:Prospective structured assessment of criteria-based depression and anxiety diagnoses within 24 hours of hospitalization with routine follow-up depression and anxiety questionnaires until discharge. Setting:A tertiary care university hospital and an affiliated Veterans Administration hospital. Patients:One hundred twenty-eight adult patients admitted to internal medicine inpatient units between May 1990 and August 1990. Main results:On admission, 43 of the 128 patients inducted met the DSM-III criteria for major depression, while an additional six met the criteria for adjustment disorder with depressed mood. Only six patients met the criteria for panic disorder, generalized anxiety disorder, or adjustment disorder with anxious mood at the time of admission to the study. Patients with high symptom scores on the anxiety and depression scales showed significant decreases in these scores without specific psychiatric intervention. Those who remained in the hospital 20 days or longer showed initial improvement and subsequently returned to baseline symptom levels of depression and anxiety. In approximately 9% of patients, symptoms of depression persisted or worsened. Conclusions:Major depression occurs more commonly than anxiety disorder in newly admitted medical inpatients but both resolve spontaneously in the majority during the course of hospitalization without specific psychiatric intervention unless the hospitalization is prolonged. One in ten will continue to show symptoms of depression. Supported by a Veterans Administration Health Services Research and Development Field Program Grant.     

The impact of comorbid anxiety and depression on alcohol treatment outcomes

AIMS: This study examines the impact of comorbid Diagnostic and Statistical Manual version IV (DSM-IV) anxiety and/or depression on out-patient treatment for alcohol problems. DESIGN: A prospective correlational design. PARTICIPANTS AND SETTINGS: Seventy-one clients seeking alcohol out-patient treatment at two treatment sites were interviewed at commencement of a treatment episode for alcohol problems and reinterviewed using the same measures 3 months later. Comorbid DSM-IV anxiety and/or depression were measured by the Composite International Diagnostic Interview (CIDI), a comprehensive interview developed by the World Health Organization to assess current and life-time prevalence of mental disorders. Outcome measures included standardized measures of disability [the short form (SF)-12 Mental Health Summary Score and the number of days taken out of role] and the average amount of alcohol consumed. Clients were also asked to rate their satisfaction with the services received. FINDINGS: Participants with comorbid DSM-IV anxiety and/or depressive disorders were more disabled and drank more heavily than those without these comorbid disorders at entry to treatment. At 3-month follow-up both groups of participants (i.e. those with and without DSM-IV comorbid anxiety and/or depression) were significantly less disabled and also drank significantly less alcohol on an average drinking occasion than at baseline. Despite this, the comorbid group remained more disabled and drank more heavily than the non-comorbid group at follow-up. CONCLUSIONS: Further research is needed to determine the most appropriate model of care for alcohol treatment seekers with comorbid DSM-IV anxiety and/or depression.     

Practice guidelines and late-life depression assessment in long-term care

To determine how well nursing home physicians believe they can detect and treat depression, we conducted a national survey, eliciting a 63% response rate. More than 75% of respondents believed they detected and treated depression well. Excellent depression training (vs "good," "fair," "poor/none") was associated with better self-reported recognition (odds ratio [OR] 14.25; 95% confidence interval [CI] 1.81, 111.93) and treatment skills (OR 6.72; 95% CI 1. 91, 23.64). Screening tool use predicted greater self-assessed detection (OR 1.89; 95% CI 0.92, 3.87) and treatment competency (OR 2.00; 95% CI 1.14, 3.50). Practice guideline awareness was associated with greater self-reported treatment competency (OR 2.47; 95% CI 1.56, 3.91).     

Medical comorbidity and rehabilitation efficiency in geriatric inpatients

OBJECTIVES: To measure and describe medical comorbidity in geriatric rehabilitation patients and investigate its relationship to rehabilitation efficiency. DESIGN: Prospective, multivariate, within-subject design. SETTING: The Geriatric Rehabilitation inpatient unit of the SCO Health Service in Ottawa, Canada. PARTICIPANTS: One hundred ten patients, with a mean age of 82 years. MEASUREMENTS: The rehabilitation efficiency ratio, based on gains in functional status achieved with rehabilitation treatment, and the length of stay were computed for all patients. Values were regressed on the scores of the Cumulative Illness Rating Scale (CIRS), the Mini-Mental State Examination, and the Geriatric Depression Scale to establish predictive power. RESULTS: The findings suggest that geriatric rehabilitation patients experience considerable medical comorbidity. Sixty percent of patients had impairments across six of the 13 dimensions of the CIRS, whereas 36% of patients had impairments across 11 of the 13 dimensions. In addition, medical comorbidity was negatively related to rehabilitation efficiency. This relationship was significant even after controlling for age, cognitive status, depressive symptoms, and functional independence status at admission. CONCLUSION: Medical comorbidity was a significant predictor of rehabilitation efficiency in geriatric patients. Comorbidity scores >5 were prognostic of poorer rehabilitation outcomes and can serve as an empirical guide in estimating a patient's suitability for rehabilitation. Medical comorbidity predicted both the overall functional change achieved with retabilitation (Functional Independence Measure gains) and the rate at with which those gains were reached (rehabilitation efficiency ratio).     

Association between depression and concurrent Type 2 diabetes outcomes varies by diabetes regimen

Aims Although depression has weak associations with several Type 2 diabetes mellitus (DM) outcomes, it is possible that these associations are concentrated within certain patient subgroups that are more vulnerable to their effects. This study tested the hypothesis that depression is related to glycaemic control and diabetes‐related quality of life (DQOL) in patients who are prescribed injected insulin, but not those on oral glucose‐lowering agents alone. Methods Participants (103 on insulin, 155 on oral glucose‐lowering agents alone) with Type 2 DM were recruited from a large US healthcare system and underwent assessment of glycaemic control (glycated haemoglobin; HbA_1c), medication adherence and diabetes self‐care behaviours, DQOL and depression (none, mild, moderate/severe). Results There was a significant regimen × depression interaction on HbA_1c (P = 0.002), such that depression was associated with HbA_1c in patients using insulin (β = 0.35, P < 0.001) but not in patients using oral agents alone (β = –0.08, P = NS). There was a similar interaction when quality of life was analysed as an outcome (P = 0.002). Neither effect was mediated by regimen adherence. Conclusions The generally weak association between depression and glycaemic control is concentrated among patients who are prescribed insulin. Similarly, the association between depression and illness quality of life is strongest in patients prescribed insulin. Because this is not attributable to depression‐related adherence problems, psychophysiological mechanisms unique to this group ought to be carefully investigated. Clinicians might be especially vigilant for depression in Type 2 DM patients who use insulin and consider its potential impact upon their illness course.     

Effect of race and sex on primary care physicians' diagnosis and treatment of late-life depression

OBJECTIVES: To examine primary care physician (PCP) contributions toward racial and sex differences in the diagnosis and treatment of late-life depression. DESIGN: Survey using a computerized instrument incorporating video interviews and text, with volunteer PCPs randomly assigned to one of four standardized video vignettes of an elderly patient depicting late-life depression. Vignettes differed only in the patient/actor's race (white/African-American) or sex. SETTING: American Academy of Family Physicians meeting, San Diego, California, 2002. PARTICIPANTS: One hundred seventy-eight U.S.-practicing postresidency PCPs who were asked to participate in a clinical decision-making study. MEASUREMENTS: The computerized survey instrument assessed PCPs' diagnoses, first-line treatment and management recommendations, and judgment of personal characteristics/behaviors for the patients in the vignettes. RESULTS: Eighty-five percent of all PCPs correctly diagnosed the elderly patient(s) with major depression. There were no significant differences in the diagnosis of depression, treatment recommendations, or PCP assessment of most patient characteristics by the race or sex of the patient/actor in the vignette, but PCP characteristics, most notably the location of medical school training (U.S. vs international), affected the likelihood of a depression diagnosis and treatment recommendations. CONCLUSION: Given standardized symptom-pictures, PCPs are just as likely to diagnose and treat depression in African-American as in white older people, suggesting that bias based simply on apparent patient race is not a likely explanation for the lower rates of depression diagnosis and treatment in older African Americans. PCPs who have trained at international medical schools may benefit from targeted training initiatives on the diagnosis and treatment of late-life depression.     

Mortality, symptoms, and functional impairment in late-life depression

OBJECTIVE: To determine whether depressive symptoms measured at baseline are associated with mortality and to describe the course of depressive symptoms and their relation to physical decline in patients over a 6-year period. DESIGN: Prospective cohort study conducted from 1990 through 1996. SETTING: Urban academic primary care group practice. PATIENTS: A cohort of 3,767 patients aged 60 years and older screened for depressive symptoms during routine office visits using the Centers for Epidemiologic Studies Depression Scale (CES-D) participated in the mortality study. A subsample of 300 patients with CES-D scores 16 or above and a subsample of 100 patients with CES-D scores less than 16 participated in the study of the course of depressive symptoms and physical decline. MEASUREMENTS AND MAIN RESULTS: Mortality by December 1995 was measured for all screened patients; reinterviewed patients completed the CES-D and the Sickness Impact Profile (SIP). The mean follow-up period was 45 months (± SD 12.2 months); 561 (14.9%) of the patients died by December 1995. In proportional hazards models, age, gender, race, history of smoking, serum albumin value, and an ideal body weight in the lowest 10% were significant correlates of time to death, but the baseline CES-D was not. Patients with depressive symptoms had significantly worse physical and psychosocial functioning scores on the SIP than did patients without depressive symptoms. Using the generalized estimating equation method, the strongest predictor of the current CES-D score was the patient’s prior CES-D score. However, worsening physical functioning score on the SIP was also independently correlated with worse CES-D scores (p ≤ .001). CONCLUSIONS: Symptoms of depression were not associated with mortality in this cohort of older adults. However, patients with depressive symptoms reported greater functional impairment than did those without depressive symptoms. Moreover, decline in physical functioning was independently correlated with a concurrent increase in depressive symptoms.

Protective association between neighborhood walkability and depression in older men

OBJECTIVES: To evaluate the association between neighborhood walkability and depression in older adults. DESIGN: Cross-sectional analysis using data from Adult Changes in Thought (ACT), a prospective, longitudinal cohort study. SETTING: King County, Washington. PARTICIPANTS: Seven hundred forty randomly selected men and women aged 65 and older, cognitively intact, living in the same home for at least 2 years. MEASUREMENTS: Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale. The Walkable and Bikable Communities Project provided objective data predicting the probability of walking at least 150 minutes per week in a particular neighborhood. ACT data were linked at the individual level via a geographic information system to this walkability score using buffer radii of 100, 500, and 1,000 meters around the subject's home. Multiple regression analysis tests were conducted for associations between the buffer-specific neighborhood walkability score and depressive symptoms. RESULTS: There was a significant association between neighborhood walkability and depressive symptoms in men when adjusted for individual-level factors of income, physical activity, education, smoking status, living alone, age, ethnicity, and chronic disease. The odds ratio for the interquartile range (25th to 75th percentile) of walkability score was 0.31 to 0.33 for the buffer radii (P=.02), indicating a protective association with neighborhood walkability. This association was not significant in women. CONCLUSION: This study demonstrates a significant association between neighborhood walkability and depressive symptoms in older men. Further research on the effects of neighborhood walkability may inform community-level mental health treatment and focus depression screening in less-walkable areas.     

The effect of hospitalization with medical illnesses on the suicide risk in the oldest old: a population-based register study

OBJECTIVES: To compare the effect of hospitalization with medical illnesses on the suicide risk in the oldest old (> or = 80) with that in the old (65-79) and middle-aged (52-64) using nationwide data. DESIGN: Event-history analysis using time-varying covariates based on prospective individual-level register data. SETTING: Population-based record linkage. PARTICIPANTS: All persons aged 52 and older living in Denmark during 1996 to 1998 (N=1,684,205). MEASUREMENTS: The studied event is completed suicide. The following time-varying variables are included in the analysis: current age, hospitalization with medical illnesses within previous 2 years, and number of different medical diagnoses given at hospitalizations within previous 2 years. Relative suicide risks were calculated using event-history analysis. The proportional attributable risk was calculated to assess to which extent hospitalization can explain the increased suicide risk in the oldest old. RESULTS: During the 3-year study period, 1,184 persons committed suicide. Hospitalization with medical illnesses was associated with an increased suicide risk in the study population. The highest suicide rates were found in the oldest-old men who had been hospitalized during the previous 2 years: 113 per 100,000 versus 80 per 100,000 in the general population of men aged 80 and older. Also, the oldest-old women with a history of hospitalization had a higher suicide rate than their peer group. Nevertheless, the oldest old experienced a lower increase in risk after hospitalization than the middle-aged. Experiencing three or more different diagnoses increased the risk further. Almost two-thirds of the oldest old who committed suicide had experienced a medical hospitalization during a 2-year period preceding the suicide. A substantial part of the greater suicide rate in the oldest old than in the middle-aged can be attributed to the increased prevalence of medical hospitalization. CONCLUSION: The oldest old who have been hospitalized with medical illnesses have a significantly higher suicide risk than people in the same age range with no hospitalization, although they experience a lower increase in risk after hospitalization than the middle-aged. The increased prevalence of medical illnesses explains a part of the greater suicide risk with age, especially for the oldest old women. Considering that hospitalization with medical illness often precedes suicide in the oldest old, hospitalization may play an important role in identification of suicidal ideation in older people.

Onset of depression in elderly persons after hip fracture: implications for prevention and early intervention of late-life depression

OBJECTIVES: To identify predictors of onset of major depressive disorder (MDD) and of depressive symptoms in subjects who suffered a hip fracture. DESIGN: Prospective naturalistic study. SETTING: University of Pittsburgh Medical Center-Shadyside, a large urban hospital in Pittsburgh, Pennsylvannia. PARTICIPANTS: One hundred twenty-six elderly patients who received surgical fixation for hip fracture and who were not experiencing a major depressive episode at the time of the fracture; severely cognitively impaired persons were excluded. MEASUREMENTS: Subjects were evaluated at the time of hospital discharge using a battery of clinical measures (including apathy measured using the Apathy Evaluation Scale (AES), delirium, cognitive measures, social support, and disability level). Depression was assessed at the end of the surgical stay, 2 weeks later, and then monthly for 6 months, using the Hamilton Rating Scale for Depression (Ham-D) to evaluate symptomatology and the Primary Care Evaluation of Mental Disorders to evaluate diagnosis of MDD. RESULTS: Eighteen of 126 subjects (14.3%) developed MDD after hip fracture. Of these, 11 developed MDD by the end of the hospitalization, and seven developed MDD between 2 and 10 weeks later. Logistic regression showed that baseline apathy score, as measured using the AES, was the only clinical measure associated with the development of MDD (odds ratio=1.09, 95% confidence interval=1.03-1.16, P=.003); 46.2% of those with high AES scores developed MDD, versus 10.9% of those with lower scores. In contrast, cognitive variables, delirium, disability after hip fracture, and other factors related to the fracture (e.g., fracture type) were not associated with MDD. A repeated-measures analysis with Ham-D over time as a dependent variable generally confirmed these findings; depressive symptoms were highest immediately after the fracture, and apathy and delirium scores were associated with higher depressive symptom levels. CONCLUSION: The onset of MDD is common after hip fracture, and the greatest period of risk is immediately after the fracture. Individuals with clinical evidence of apathy are at high risk for developing MDD, and evaluation and close follow-up of such individuals is warranted. However, further research is needed to examine other candidate variables (e.g., clinical measures or biomarkers) to model adequately the risk for MDD after hip fracture and other disabling medical events.     

Effectiveness of screening and treatment for depression in ambulatory indigent patients

OBJECTIVE: To determine the effectiveness of screening and treatment for depression among ambulatory indigent patients visiting resident physicians. DESIGN: Two-group randomized trial (N = 33 intervention, N = 28 usual care) with baseline, 6-month, and 12-month outcome measurements. SETTING: Internal Medicine Residency Clinic. PATIENTS: Clinic patients over 18 years of age who screened positive for depression on the PRIME-MD during a visit to their resident physician. Patients were not receiving treatment nor seeking care for any emotional problems. All patients were either enrolled in Medicaid or had income below the poverty line. INTERVENTION: Resident physicians were educated to follow AHCPR (AHRQ; Agency for Healthcare Research and Quality) guidelines for diagnosis and treatment of depression in a primary care setting. For the intervention group patients, a screening nurse advised residents regarding the positive screen, handed them a standardized protocol outline, and attempted to arrange behavioral care. The patients in the usual care group were provided the results of the screen by the screening nurse before their visit with the resident, and advised to seek care for their symptoms. MAIN RESULTS: Results for the primary outcome of depression symptoms measured with the Beck Depression Inventory (BDI) demonstrated that intervention was successful in reducing symptoms relative to usual care (difference = -4.9 BDI points, P =.05, 95% confidence interval [CI], -9.8 to -0.005 effect size = -0.41). During the 12-month follow-up, 70% of intervention patients were treated for depression (of these, 91% with antidepressants), while 15% of usual care patients were treated with antidepressants for depression. Another 18% of the usual care group had depression noted, but no treatment was identified. BDI differences between intervention and control groups were similar at the 6- and 12-month measures. Quality of life and costs were also measured, but differences between the groups were not significant in this regard. CONCLUSION: Screening and treatment for depression by resident physicians was successful in reducing symptoms relative to usual care in an indigent population. Almost twice as many intervention patients as usual care controls demonstrated a substantial reduction (10 BDI points) in symptoms related to depression.
