Translation of a Dementia Caregiver Support Program in a Health Care System—REACH VA

BACKGROUND Based on the National Institute on Aging/National Institute of Nursing Research Resources for Enhancing Alzheimers Caregiver Health (REACH) randomized controlled trial (REACH II), REACH VA (Department of Veterans Affairs) was the first national clinical translation of a proven behavioral intervention for dementia caregivers, running from September 2007 through August 2009. This article describes the population and outcomes of the REACH VA translation of REACH II into the VA. METHODS Clinical staff members from 24 VA Medical Center Home-Based Primary Care programs in 15 states delivered the intervention to stressed caregivers of patients with dementia. Like REACH II, the 6-month REACH VA intervention, structured through a protocol and individualized through a risk assessment, targeted education, support, and skills training to address caregiving risk areas of safety, social support, problem behaviors, depression, and health through 12 individual in-home and telephone sessions and 5 telephone support group sessions. Staff members of the Memphis VA Medical Center, Memphis, Tennessee, collected data on burden, depression, health and healthy behaviors, caregiving frustrations, social support, dementia-related behaviors, and time spent providing care and on duty. RESULTS From baseline to 6 months, caregivers reported significantly decreased burden, depression, impact of depression on daily life, caregiving frustrations, and number of troubling dementia-related behaviors. A 2-hour decrease in hours per day on duty approached significance. Caregivers (96%) believed that the program should be provided by the VA to caregivers. CONCLUSIONS This clinical translation achieved outcomes similar to the REACH II randomized controlled trial, providing clinically significant benefits for caregivers of a veteran with a progressive dementing disease. This model of caregiver support can inform public policy in providing assistance to caregivers.

REACH VA: Moving from Translation to System Implementation

PURPOSE OF THE STUDY Resources for Enhancing All Caregivers Health in the Department of Veterans Affairs (REACH VA) has been implemented in the VA system as a national program for caregivers. DESIGN AND METHODS We describe the trajectory of REACH VA from national randomized clinical trial through translation to national implementation. The implementation is examined through the six stages of the Fixsen and Blasé implementation process model: exploration and adoption, program installation, initial implementation, full operation, innovation, and sustainability. Different drivers that move the implementation process forward are important at each stage, including staff selection, staff training, consultation and coaching, staff evaluation, administrative support, program evaluation/fidelity, and systems interventions. RESULTS Caregivers in the REACH VA 4 session intervention currently implemented in the VA had similar outcomes to longer REACH interventions, including Resources for Enhancing Alzheimers Caregivers Health (REACH II). Caregivers experienced significant decreases in burden, depression, anxiety, number of troubling patient behaviors reported, caregiving frustrations, stress symptoms (feeling overwhelmed, feeling like crying, being frustrated as a result of caregiving, being lonely), and general stress. Effect sizes (Cohens d) for these significant variables were between small and medium ranging from .24 to .46. IMPLICATIONS The implementation of REACH VA provides a road map for implementation of other behavioral interventions in health care delivery settings. Lessons learned include the importance of implementing a proven, needed intervention, support from both leadership and clinical staff, willingness to respond to staff and organization needs and modify the intervention while preserving its integrity, and fitting the intervention into ongoing routines and practices.

Easing Reintegration: Telephone Support Groups for Spouses of Returning Iraq and Afghanistan Service Members

Spouses of returning Iraq (Operation Iraqi Freedom, OIF) and Afghanistan (Operation Enduring Freedom, OEF) military service members report increased depression and anxiety post deployment as they work to reintegrate the family and service member. Reconnecting the family, renegotiating roles that have shifted, reestablishing communication patterns, and dealing with mental health concerns are all tasks that spouses must undertake as part of reintegration. We tested telephone support groups focusing on helping spouses with these basic reintegration tasks. Year-long telephone support groups focused on education, skills building (communication skills, problem solving training, cognitive behavioral techniques, stress management), and support. Spouse depression and anxiety were decreased and perceived social support was increased during the course of the study. In subgroup analyses, spouses with husbands whose injuries caused care difficulties had a positive response to the intervention. However, they were more likely to be depressed, be anxious, and have less social support compared to participants who had husbands who had no injury or whose injury did not cause care difficulty. Study findings suggest that this well-established, high-access intervention can help improve quality of life for military spouses who are struggling with reintegration of the service member and family.

A Trial of Dementia Caregiver Telephone Support

The purpose of this study was to determine if telephone support groups for dementia caregivers have an effect on bother with patient behaviours, burden, depression, and general well-being. The randomized controlled trial compared telephone support groups (15 groups of 5 or 6 caregivers) with control groups (print materials). Groups met 14 times over 1 year. The 1-hour sessions included content on education, coping skills, and support. Data were collected at baseline and at 6 and 12 months. The sample comprised 154 caregivers, 77 per arm, providing care to veterans with dementia or a veteran caregiver. Bother was found to differ significantly at baseline. There were no significant treatment effect differences between study arms. Participants anecdotally reported improvement. It was concluded that telephone support groups are an efficient way to interact with caregivers. Further research should test different models of care. Interventions that are targeted to specific needs or occur frequently may provide better support for caregivers of individuals with a worsening condition.

Metformin Has a Positive Therapeutic Effect on Prostate Cancer in Patients With Type 2 Diabetes Mellitus

Objective: Prostate cancer and type 2 diabetes mellitus (DM2) are both common diseases found in the elderly male population. The diabetic drug, metformin, has been shown to have antineoplastic properties and demonstrated better treatment outcomes when used as adjuvant therapy in patients with breast cancer. The hormonally‐sensitive cancer analogous to breast cancer in men is prostate cancer. We investigated improved survival, lower risks of recurrences, and lower, more stable levels of prostate‐specific antigen (PSA) in patients with DM2 along with prostate cancer on metformin. Methods: Patients with prostate cancer along with DM2 who remained on metformin were compared with controls who were not on metformin matched by age, weight, race and Gleason score cancer staging. The endpoints of our study included final PSA values, number of recurrences, metastases and number living for each group. Results: There were significantly fewer deaths (23% versus 10%), fewer recurrences (15% versus 8%), fewer metastases (5% versus 0%) and fewer secondary cancers (17% versus 6%) in the metformin group (P < 0.004). The final PSA value was lower in the metformin‐treated group with a result approaching significance (P = 0.067). The primary treatments for prostate cancer (ie, surgery, radiation and androgen depletion) were found to be comparable in both the groups. Conclusions: Our retrospective study shows that adjuvant metformin therapy leads to a better prognosis in prostate cancer. Not only are PSA levels controlled for several years but also there are significantly fewer cancer recurrences in metformin‐treated patients. Overall, these results are promising and should be followed up with a prospective study to assess long‐term survival.

Metformin Has Positive Therapeutic Effects in Colon Cancer and Lung Cancer

Background: Metformin (MF), a diabetic drug, has antineoplastic activity as adjuvant therapy for breast cancer and prostate cancer. MF is thought to work via inhibition of mammalian target of rapamycin and activation of p53 and liver kinase B1 via adenosine 5′‐monophosphate–activated protein kinase. We investigated survival, recurrences and metastasis in patients with type 2 diabetes mellitus (DM2) along with colorectal cancer (CC) or lung cancer (LC) taking MF using the electronic medical record in Memphis Veterans Affairs Medical Center (colon, n = 202; lung, n = 180). Materials and Methods: Patients with CC or LC and DM2 on MF were compared to controls taking any medication except MF. Recurrences, metastases, secondary cancers, survival and carcinoembryonic antigen levels were compared using t test and chi‐squared test. Inclusion criteria were based on MF use, CC or LC diagnosis and DM2. Results: For CC, the MF group noted fewer deaths (48% versus 76%, P < 0.001), recurrences (4% versus 19%, P = 0.002), metastases (23% versus 46%, P = 0.001), better 5‐year survival rates (57% versus 37%, P = 0.004), overall survival years (5.7 versus 4.1, P = 0.007) and greater carcinoembryonic antigen decrease (72% versus 47%, P = 0.015). MF was associated with improved 5‐year survival rates (29% versus 15%, P = 0.023) and overall survival years (3.4 versus 1.8, P < 0.001) in LC. Conclusions: Our study shows that MF therapy is associated with significantly better prognosis in patients with CC and improved survival in LC. Patients with CC on MF had fewer recurrences and metastases. Differences in metabolic pathways between CC and LC likely account for the differences in the effect of MF.

Typical and Atypical Dementia Family Caregivers: Systematic and Objective Comparisons.

This systematic, objective comparison of typical (spouse, children) and atypical (in-law, sibling, nephew/niece, grandchild) dementia family caregivers examined demographic, caregiving and clinical variables. Analysis was of 1,476 caregivers, of whom 125 were atypical, from the Resources for Enhancing Alzheimers Caregivers Health (REACH I and II) studies. Based on statistical and clinical significance, there were large effects for demographics but no large effects among caregivers or care recipients on clinical and caregiving variables. Non-spouse family members were more likely to be caring for women and unmarried individuals. Grandchildren and nieces/nephews provided care for older care recipients. For care recipients who are unmarried, older, or women, fewer care possibilities may be available; consequently family members other than spouse or children may become their caregivers. Once an individual becomes a caregiver, the clinical experience of dementia caregiving is similar across caregiver types. These findings have implications for clinical care and public policy.

Smoking and Smoking Increase in Caregivers of Alzheimer’s Patients

PURPOSE OF THE STUDY The relationship between stress and smoking has been established, but there is little research on the effects of stress and coping on smoking in caregivers of Alzheimers disease patients. This study examines how caregiver stressors and coping resources explain smoking status and recent smoking increase. DESIGN AND METHODS Data were obtained from the Resources for Enhancing Alzheimers Caregivers Health (REACH II) study. Analyses identified differences between caregiver smokers and nonsmokers and between caregiver smokers who reported a recent smoking increase and those who did not. Variables that were significantly different between the groups were examined in two logistic regression analyses to explain smoking status and smoking increase. RESULTS Of 642 caregivers, nearly 40% reported smoking and 25% of smokers reported recent increase in smoking. Younger caregivers were more likely to report smoking. Explanatory variables for smoking increase were being Caucasian or African-American, higher depression scores, and less caregiving skills. IMPLICATIONS This study demonstrates that smoking among caregivers is a valid public health concern. Further investigation of ways that explanatory variables affect smoking status and increase in caregivers, and incorporation of smoking cessation strategies that address depression and low caregiving skills, seem warranted in future caregiver interventions.

Anxiety, social support, and physical health in a sample of spouses of OEF/OIF service members.

The goal of this study was to examine the relationships between heightened anxiety, social support, and physical health in a sample of spouses of returning Iraq and Afghanistan service members. 86 spouses were recruited nationally as part of a pilot trial of a military spouse telephone support group. Participants completed measures of physical and mental health via telephone including a screening tool for generalized anxiety disorder (GAD). Scores for social support and health outcomes were compared across two groups (positive vs. negative screens for GAD) using one-way analysis of variance analysis procedures. Path analytic techniques were used to evaluate the relative effects of anxiety and perceived social support on overall health and physical health comorbidities. A total of 38 participants screened positive for GAD. Participants with probable GAD reported having less social support than those screening negative for GAD. GAD participants also reported poorer overall health and more physical health comorbidities than their GAD-negative counterparts. Path analysis indicated that heightened anxiety is associated with worse overall health and social support does not buffer this interaction. The results suggest that anxiety-related health is a critical factor to be addressed in spouses of service members.
