In response to Program Announcement (PA)-09-164, "NIH Exploratory/Developmental Research Grant Program (R21) a randomized pilot study testing the efficacy of SWIFT: Social Work Intervention Focused on Transitions among at-risk older adults following hospital discharge to home. This study is drawn from several observations. First, transitions between care settings create elevated risk for poor outcomes and for readmission among older adults leaving the hospital for home largely due to fragmented care and poor communication. Next, while few studies exist that test methods to improve transitions, those available are largely medically focused, using a nurse or advanced practice nurse in their approach. Although evidence exists to support the effectiveness of these models, few have been replicated and none have been integrated into standard health care practice. This may be attributed to several factors including the availability of the needed staff, the lack of existing structures to support these roles, and the costs of implementing these interventions. Finally, a social work driven intervention may provide a replicable mechanism for bridging medical care, addressing psychosocial needs as well as medical needs, and improving linkages with community services while reducing care duplication. This study aimed to test a structured social work transition intervention model to reduce rates of hospital readmission and medical service use while improving patient satisfaction with the care transition process. A randomized pilot study was used to test a social work transitions model designed to improve care provided to frail older adults being discharged from the hospital to return to the community. Eligible patients consenting to participate (n=181) were randomly assigned to either the social work transitions model intervention or usual care. This project was conducted at Huntington Hospital, a 525-bed, nonprofit, community hospital located in Pasadena, California. In an average year, Huntington Hospital has approximately 10,000 older adults discharged from their facility, 44% of who are 80 years old or older. Those randomized to the intervention arm received up to six sessions from the social worker, at least one provided in the home. The social work intervention was designed to overcome common problems following hospital discharge including medication review, discussion and planning around discharge instruction, assistance in scheduling follow up appointments, assessments of psychosocial and other support service needs and provision of linkages to address those needs. Outcomes were measured three and six months following arrival at home, with an interim measure of satisfaction at 10 days following arrival at home, with measures including patient level of depression, pain, physical functioning, self-efficacy with disease management, and medical service use.
Many studies have shown that exercise training is beneficial for patients with chronic heart failure (CHF). Heart Foundation guidelines strongly recommend regular physical activity and referral to a specifically designed rehabilitation program for all patients with CHF who are medically stable. Such programs usually comprise aerobic exercises such as walking, and light weightlifting with care to avoid heavy straining due to stress that this may place on the heart. Eccentric contractions are those in which the muscle lengthens as it contracts. Exercise involving eccentric contractions is known to increase muscle strength and this type of exercise also requires less oxygen. This is because it requires less power to resist lowering a weight than it does to lift a weight. Initial evidence suggests that this form of exercise has favourable outcomes in the frail elderly and those with chronic disease. This study aims to determine if eccentric exercise can be applied to patients with heart failure to increase their physical function while using less energy so that exercise is more tolerable for patients who complain of significant breathlessness and fatigue. This study also aims to determine if eccentric exercise is a safe alternative exercise option for patients at risk of negative events. The investigators propose to run a randomised controlled trial. Eccentric exercise will be delivered to a group of heart failure patients referred to the existing heart failure rehabilitation program at the Northern Hospital. The program will consist of eight weeks of twice weekly exercise of one hour's duration comprising eccentric exercise combined with walking and light weight training. This will be compared to a group of patients participating in the current exercise program consisting of light weightlifting and aerobic exercises for the same length and duration of exercise and also to a third group of patients who will be wait listed for 8 weeks. Following the completion of the eight week waiting period, these patients will be offered the option of joining the standard exercise program. The investigators expect that the eccentric exercise group will have improved walking capacity and quality of life compared with the traditional program and the wait-list control group. It is also possible that there is no difference between the eccentric and traditional program in terms of functional outcomes but that the participants report that eccentric exercise is easier.
The purpose of this study is to verify the effects of exercise training on sympathetic modulation and arterial baroreflex control in patients with chronic heart failure.
In the US, racial and ethnic disparities persist, even when income, health insurance and care access are addressed. For example, there is a greater prevalence of chronic heart failure (CHF), higher rates of hospital use and higher death rates in blacks as compared to whites. This is due to many factors including: reduced healthcare access, higher prevalence of hypertension,coronary artery disease, systolic dysfunction, myocardial infarction and obesity. Given the magnitude of this chronic health issue, the growth of the elderly population, and increases in ethnic diversity, providers need to develop new ways of caring for those with chronic conditions living in health disparity communities. The investigators propose to implement a randomized study with health disparity community-dwelling patients. A bilingual clinician will follow patients for 3 months after hospitalization for CHF to test this approach for the proposed health disparity population. The investigators will obtain patient/caregiver input at multiple points during the research to make necessary adjustments to the intervention to ensure that disparity patients accept/use the system, and are satisfied. To ensure that proposed outcomes have relevance for patients, a Community Advisory Board (CAB) of stakeholders will advise the study team throughout the study process. The investigators believe that studying patient use of TSM over a 3 month period will: 1) identify cost-effective care approaches for patients living with chronic disease; 2) involve the patient in identifying and testing approaches that work for them; 3) enhance provider-patient communication; 4) teach the patient how to self-monitor and explore his/her role in self-care; 5) improve patient education about treatment options and 6) explore how "usable" the patients feel the program is. If our goals are achieved, these strategies will result in patient-led improvements in health, satisfaction and quality of life. Knowledge gained will further understanding of the use of telehealth programs as effective self-management tools.
The purpose of this study is to determine if oral iron (FE) polysaccharide is superior to oral placebo in improving functional capacity as measured by change in peak VO2 by CPET (Cardiopulmonary Exercise Testing) , of a broad population of patients with HFrEF (Heart Failure Exercise Testing) and Fe deficiency at 16 weeks. Hypothesis: In a broad population of HFrEF patients with Fe deficiency, compared to oral placebo, therapy with oral Fe polysaccharide will be associated with improvement in functional capacity at 16 weeks as assessed by CPET.
The purpose of this study is to investigate the non-inferiority of bisoprolol to carvedilol by evaluating tolerability (The probability that administered maintenance dose reaches the maximum will be determined as an indicator) as a primary endpoint when bisoprolol or carvedilol is administered for 48 weeks to Japanese chronic heart failure patients. In addition, the safety and efficacy of bisoprolol will be investigated.
Sleep disordered breathing is very common in patients with chronic heart failure with reported prevalence rates of 50-75%. Adaptive Servo-Ventilation (ASV) can be used to treat sleep apnea in these patients. This is an observational study to document changes in respiratory parameters in HF patients using ASV for a period of 12 months.
Heart failure is a serious and common disease. HF is marked by a high rate of preventable hospitalizations through proper care. As such, it is a key target for telemedicine programs. However, currently published data are inconclusive. Investigators propose a multicenter randomized study of innovative telemedicine involving the usual patient monitoring daily weight monitoring, clinical signs and in one of three groups in our study of BNP testing in the patient's home all associated with a regular education reinforcement. The objective is to identify early cardiac decompensation to allow to treat ambulatory and thus prevent the occurrence of more serious events such as death or rehospitalization.
Evaluate pro-BNP levels, oxygen consumption, functional class, and quality of life in patients with chronic heart failure after participating in an exercise program and compare them baseline and 2 months, with another group who underwent an educational program.
