Patient and Caregiver Characteristics Associated with Depression in Caregivers of Patients with Dementia

OBJECTIVE: Many patients with dementia who live at home would require nursing home care if they did not have the assistance of family caregivers. However, caregiving sometimes has adverse health consequences for caregivers, including very high rates of depression. The goal of this study was to determine the patient and caregiver characteristics associated with depression among caregivers of patients with dementia.DESIGN: Cross-sectional study.PARTICIPANTS AND SETTING: Five thousand six hundred and twenty-seven patients with moderate to advanced dementia and their primary caregivers upon enrollment in the Medicare Alzheimer’s Disease Demonstration (MADDE) at 8 locations in the United States.MEASUREMENTS: Caregiver depression was defined as 6 or more symptoms on the 15-item Geriatric Depression Scale. Patient characteristics measured included ethnicity and other demographic characteristics, income, activities of daily living (ADL) function, Mini-Mental Status Exam (MMSE) score, and behavioral problems. Caregiver characteristics measured included demographic characteristics, relationship to the patient, hours spent caregiving, and ADL and Instrumental Activities of Daily Living (IADL) function. We used x2 and t tests to measure the bivariate relationships between patient and caregiver predictors and caregiver depression. We used logistic regression to determine the independent predictors of caregiver depression.RESULTS: Thirty-two percent of caregivers reported 6 or more symptoms of depression and were classified as depressed. Independent patient predictors of caregiver depression included younger age (odds ratio [OR], 1.91; 95% confidence interval [CI], 1.33 to 2.76 in patients less than 65 years compared to patients over 85 years), white (OR, 1.53; 95% CI, 1.18 to 1.99) and Hispanic ethnicity (OR, 2.50; 95% CI, 1.69 to 3.70) compared to black ethnicity, education (OR, 1.16; 95% CI, 1.01 to 1.33 for those with less than a high school education), ADL dependence (OR, 1.55; 95% CI, 1.26 to 1.90 for patients dependent in 2 or more ADL compared to patients dependent in no ADL), and behavioral disturbance, particularly angry or aggressive behavior (OR, 1.47; 95% CI, 1.27 to 1.69 for patients with angry or aggressive behavior). Independent caregiver predictors of depression included low income (OR, 1.45; 95% CI, 1.18 to 1.77 for less than

Efforts to identify and treat caregiver depression will need to be multidisciplinary and focus on multiple risk factors simultaneously.

Identification of medications that cause cognitive impairment in older people: the case of oxybutynin chloride.

OBJECTIVE: Little is known about patients who skip doses or otherwise avoid using their medications because of cost. We sought to identify which elderly patients are at highest risk of restricting their medications because of cost, and how prescription coverage modifies this risk.DESIGN AND PARTICIPANTS: Cross-sectional study from the 1995–1996 wave of the Survey of Asset and Health Dynamics Among the Oldest Old, a population-based survey of Americans age 70 years and older.MEASUREMENTS: Subjects were asked the extent of their prescription coverage, and whether they had taken less medicine than prescribed for them because of cost over the prior 2 years. We used bivariate and multivariate analyses to identify risk factors for medication restriction in subjects who lacked prescription coverage. Among these high-risk groups, we then examined the effect of prescription coverage on rates of medication restriction.MAIN RESULTS: Of 4,896 seniors who regularly used prescription medications, medication restriction because of cost was reported by 8% of subjects with no prescription coverage, 3% with partial coverage, and 2% with full coverage (P<.01 for trend). Among subjects with no prescription coverage, the strongest independent predictors of medication restriction were minority ethnicity (odds ratio [OR], 2.9 compared with white ethnicity; 95% confidence interval [95% CI], 2.0 to 4.2), annual income <

20; 95% CI, 1.5 to 7.2). The prevalence of medication restriction in members of these 3 risk groups was 21%, 16%, and 13%, respectively. Almost half (43%) of subjects with all 3 risk factors and no prescription coverage reported restricting their use of medications. After multivariable adjustment, high-risk subjects with no coverage had 3 to 15 times higher odds of medication restriction than subjects with partial or full coverage (P<.01).CONCLUSIONS: Medication restriction is common in seniors who lack prescription coverage, particularly among certain vulnerable groups. Seniors in these high-risk groups who have prescription coverage are much less likely to restrict their use of medications.

Pilot clinical trial of gabapentin to decrease postoperative delirium in older patients

Postoperative delirium and cognitive decline are adverse events that occur frequently in elderly patients. Preexisting patient factors, medications, and various intraoperative and postoperative causes have been implicated in the development of postoperative delirium and cognitive decline. Despite previous studies identifying postoperative pain as a risk factor, relatively few clinical studies have compared the effect of common postoperative pain management techniques (IV and epidural) or opioid analgesics on postoperative cognitive status. A systematic search of the PubMed and CINAHL databases identified six studies comparing different opioid analgesics on postoperative delirium and cognitive decline and five studies comparing IV and epidural routes of administering analgesia. Meperidine was consistently associated with an increased risk of delirium in elderly surgical patients, but the current evidence has not shown a significant difference in postoperative delirium or cognitive decline among other more frequently used postoperative opioids such as morphine, fentanyl, or hydromorphone. The available studies also suggest that IV or epidural techniques do not influence cognitive function differently. However, future investigations of sufficient study size and more standardized methods of defining outcomes are necessary to confirm the current findings.
