In spite of the general interest in health information behaviour, there is little earlier research on how older adults, who are still active in working life but approaching retirement, differ from other age groups. A survey with Swedish patients who had ordered and read their medical record was conducted to map the preferences and motivations of older adults (born 1946–1960) ordering a copy of their medical record, and using medical records based e-health and information services in the future. The results do not indicate an obvious linear relationship between age and motivation to use online health information but show several differences between the age groups. Older adults were less interested in communication with their medical doctor by e-mail. Yet, they had searched health information in the Internet during the last week more likely than young. They were more inclined to read medical record to get an overview of their health than young, but less confident that they understood most of the content or turn to their family and friends to seek help than the elderly. When compared to younger adults and elderly people, older adults are the least confident and least motivated to use online health information. It is suggested that older adulthood can be seen as a transitory stage of life when the need of health information increases and engagement with health changes. The results agree with prior research on the potential usefulness of (online) medical records as a way to inform citizens. However, specific provision strategies may be necessary to match the needs and motivations of different age groups. 相似文献

When consumers search for health information, a major obstacle is their unfamiliarity with the medical terminology. Even though medical thesauri such as the Medical Subject Headings (MeSH) and related tools (e.g., the MeSH Browser) were created to help consumers find medical term definitions, the lack of direct and explicit integration of these help tools into a health retrieval system prevented them from effectively achieving their objectives. To explore this issue, we conducted an empirical study with two systems: One is a simple interface system supporting query-based searching; the other is an augmented system with two new components supporting MeSH term searching and MeSH tree browsing. A total of 45 subjects were recruited to participate in the study. The results indicated that the augmented system is more effective than the simple system in terms of improving user-perceived topic familiarity and question–answer performance, even though we did not find users spend more time on the augmented system. The two new MeSH help components played a critical role in participants’ health information retrieval and were found to allow them to develop new search strategies. The findings of the study enhanced our understanding of consumers’ search behaviors and shed light on the design of future health information retrieval systems. 相似文献

Multidisciplinary teams are an essential aspect of modern organizational work. These teams often work in information-rich environments but little is known about their collaborative information seeking (CIS) behavior. We have been studying the CIS behavior of teams in the context of medical care. We conducted an ethnographic field study of a multidisciplinary patient care team in an emergency department to identify (a) team information needs and (b) situations that trigger collaborative information seeking activities. We identified seven categories of information needs as expressed by questions asked by team members. The majority of questions focused on medical information, but there were a larger than expected percentage of questions focusing on organizational information. We also identified three triggers for CIS activities. These triggers are: (1) lack of expertise, (2) lack of immediately accessible information, and (3) complex information needs. The questions and triggers highlight the importance of face-to-face communication during CIS activities and how CIS activities could lead to interruptive workplaces. We also discuss organizational and technical implications for supporting CIS behavior of teams. 相似文献
