The effects on health behavior and health outcomes of Internet-based asynchronous communication between health providers and patients with a chronic condition: a systematic review.

BACKGROUND: In support of professional practice, asynchronous communication between the patient and the provider is implemented separately or in combination with Internet-based self-management interventions. This interaction occurs primarily through electronic messaging or discussion boards. There is little evidence as to whether it is a useful tool for chronically ill patients to support their self-management and increase the effectiveness of interventions. OBJECTIVE: The aim of our study was to review the use and usability of patient-provider asynchronous communication for chronically ill patients and the effects of such communication on health behavior, health outcomes, and patient satisfaction. METHODS: A literature search was performed using PubMed and Embase. The quality of the articles was appraised according to the National Institute for Health and Clinical Excellence (NICE) criteria. The use and usability of the asynchronous communication was analyzed by examining the frequency of use and the number of users of the interventions with asynchronous communication, as well as of separate electronic messaging. The effectiveness of asynchronous communication was analyzed by examining effects on health behavior, health outcomes, and patient satisfaction. RESULTS: Patients' knowledge concerning their chronic condition increased and they seemed to appreciate being able to communicate asynchronously with their providers. They not only had specific questions but also wanted to communicate about feeling ill. A decrease in visits to the physician was shown in two studies (P=.07, P=.07). Increases in self-management/self-efficacy for patients with back pain, dyspnea, and heart failure were found. Positive health outcomes were shown in 12 studies, where the clinical outcomes for diabetic patients (HbA1c level) and for asthmatic patients (forced expiratory volume [FEV]) improved. Physical symptoms improved in five studies. Five studies generated a variety of positive psychosocial outcomes. CONCLUSIONS: The effect of asynchronous communication is not shown unequivocally in these studies. Patients seem to be interested in using email. Patients are willing to participate and are taking the initiative to discuss health issues with their providers. Additional testing of the effects of asynchronous communication on self-management in chronically ill patients is needed.

Culturally sensitive care for elderly immigrants through ethnic community health workers: design and development of a community based intervention programme in the Netherlands.

BACKGROUND: In Western countries, health and social welfare facilities are not easily accessible for elderly immigrants and their needs are suboptimally addressed. A transition is needed towards culturally sensitive services to overcome barriers to make cure and care accessible for elderly immigrants. We developed an intervention programme in which ethnic community health workers act as liaisons between immigrant elderly and local health care and social welfare services. In this study we evaluate the effectiveness and the implementation of this intervention programme. METHODS/DESIGN: In a quasi experimental design, the effectiveness of introduction of community health workers, health needs assessment, and follow-up intervention programme will be evaluated in three (semi) urban residential areas in the Netherlands and compared with a control group. Community health workers are selected from local ethnic communities and trained for the intervention. Data on health perception, quality of life, and care consumption are collected at baseline and after the intervention programme. Elderly's informal care givers are included to examine caregiver burden. The primary outcome is use of health care and social welfare facilities by the elderly. Secondary outcomes are quality of life and functional impairments. The target number of participants is 194 immigrant elderly: 97 for the intervention group and 97 for the control group. Implementation of the intervention programme will be examined with focus groups and data registration of community health worker activities. DISCUSSION: This study can contribute to the improvement of care for elderly immigrants by developing culturally sensitive care whereby they actively participate. To enable a successful transition, proper identification and recruitment of community health workers is required. Taking this into account, the study aims to provide evidence for an approach to improve the care and access to care for elderly immigrants. Once proven effective, the community health worker function can be further integrated into the existing local health care and welfare system. TRIAL REGISTRATION NUMBER: ISRCTN89447795.
