Cardiopulmonary Endurance of Hospitalized Older Adults With Chronic Obstructive Pulmonary Disease

imageBackground Chronic obstructive pulmonary disease (COPD) could lead to poor cardiopulmonary endurance, which affects quality of life and increases the risk of rehospitalization or mortality. However, studies investigating associated factors of cardiopulmonary endurance for COPD inpatients are scant. Objective The aim of the study was to investigate whether and how age, gender, COPD severity, body composition, dyspnea, respiratory muscle strength, and lower limb muscle strength and endurance were related to cardiopulmonary endurance in elderly inpatients with COPD. Methods This was a cross-sectional study using a systematic sampling of older inpatients. Data of demographic characteristics such as age, gender, and disease severity were collected, and body mass index was calculated. Degrees of dyspnea were assessed by the modified Medical Research Council Dyspnea Scale. Respiratory muscle strength was reflected by the maximal inspiratory pressure and the maximal expiratory pressure. Lower limb muscle strength and endurance were assessed by a handheld dynamometer and a 30-second sit-to-stand test, respectively. Finally, cardiopulmonary endurance was assessed by a 6-minute walk test. Results A total of 83 older COPD inpatients participated. The mean age was 74.01 ± 6.93 years. Cardiopulmonary endurance was associated with age, COPD severity, dyspnea, respiratory muscle strength, lower limb muscle strength, and endurance. Predictors of cardiopulmonary endurance were disease severity, dyspnea, and lower limb muscle endurance. These predictors explained 53% of the variance in cardiopulmonary endurance in older inpatients with COPD. Discussion Cardiopulmonary endurance of hospitalized older adults with COPD should be strengthened by improving conditions of disease severity, dyspnea, and lower limb muscle endurance.

Development of a Care Delivery Model for High-Need Older Adults in the Community

imageBackground High-need older adults have multiple needs and require different types of care services. Care coordinators in community care centers in Taiwan, however, often experience difficulties in providing sufficient care services because of the inadequate capacity of case management. Objective The aim of this study was to develop a realistic care delivery model for the care coordinators to manage the care of high-need, community-dwelling older adults. Methods Focus-group interviews concerning elements and process for establishing a care delivery model were conducted with 12 care management experts in two groups: the practical work group (three registered nurses and three social workers) and the care management group (three care managers and three care management supervisors). The interviews were video-recorded and subjected to content analysis. Results A five-stage care delivery model was formulated: case screening, case assessment, care plan, care delivery, and follow-up evaluation. Six types of high-need older adults were identified: those living with disability, solitude, dementia, depression, elder abuse, and poverty. A list of categorized care services, including care resources, social welfare resources, and caregiver resources, was then used as a guide for case management and care delivery. Discussion The developed model—consisting a classification of services for different types of high-need older adults—serves as a guide for care coordinators in community care centers to make better decisions on service linkages, resource management, and care plan monitoring.
