Objectives: For general practitioners (GPs), an important obstacle to practising evidence‐based medicine is lack of time. An evidence‐based answering service was developed that took over searching and appraisal of medical evidence from the GPs. GPs sent in questions, and the informationist formulated the answers. Our objectives were to find out if such an evidence‐based answering service was feasible, including assessing the effect of the answers on GPs and their patients, as reported by the GPs. Methods: After attending a workshop on building well‐formulated questions from daily practice, the GPs sent in questions to the informationist. The literature was searched, the relevant information was appraised, and the answers to the questions were formulated. With a questionnaire, the effect of the answers on the GP and the patient was assessed, as well as the perceived barriers to implementing the answers. Results: From 26 GPs, 61 questions were received. For 12% of questions, information was found with the highest evidence level, while for 36%, no information was found. However, for 89% of the questions for which no information could be found, the answer ‘no information found’ did have an effect on the GP concerned. In total, 81% of all the answers had an effect on the GP, and, according to the GP, 52% had an effect on the patient. Few barriers to implementing the evidence were perceived. Most of the answers were found in Pubmed/Medline, the Cochrane Library and Embase. Conclusions: This study indicates that an evidence‐based answering service can have an impact on GPs and their patients. Librarians can provide an evidence‐based answering service for GPs and their patients. The evidence‐based answering service for GPs in this study had an impact on 81% of the GPs and on 52% of their patients. Although for one‐third of the questions no evidence‐based answer was found, this message in itself had an impact on 89% of the GPs. An informationist as mediator between medical information and doctors can save doctors’ time.  相似文献

Information needs of rural health professionals: a review of the literature   总被引:3,自引:0,他引:3  
This review analyzes the existing research on the information needs of rural health professionals and relates it to the broader information-needs literature to establish whether the information needs of rural health professionals differ from those of other health professionals. The analysis of these studies indicates that rural health practitioners appear to have the same basic needs for patient-care information as their urban counterparts, and that both groups rely on colleagues and personal libraries as their main sources of information. Rural practitioners, however, tend to make less use of journals and online databases and ask fewer clinical questions; a difference that correlates with geographic and demographic factors. Rural practitioners experience pronounced barriers to information access including lack of time, isolation, inadequate library access, lack of equipment, lack of skills, costs, and inadequate Internet infrastructure. Outreach efforts to this group of underserved health professionals must be sustained to achieve equity in information access and to change information-seeking behaviors.  相似文献

BACKGROUND: Numerous studies deal with the use of computers and the Internet in the health sector. Most of these studies show an increase in the use of the new technologies in searching for medical information-particularly by patients--but these uses remain very heterogeneous and depend on the studies. AIMS: The aim of this work was to consider the use of computers by French general practitioners (GPs) and to analyse the impact that computerization could have on their information-seeking behaviour. METHODS: The nature of the approach used is qualitative using interviews. RESULTS: Most of the GPs interviewed are equipped with a computer. The policies of the government were supposed to give financial incentives for GPs to start using computers for the management of administrative procedures, but many physicians do not know how to use the new tools properly. Their computers are, in most cases, underused for searching for medical information. Most of the time, the Internet sources are thought to be unreliable. CONCLUSION: This study sheds light on the use of computers and the preferences of GPs in searching for medical information.  相似文献

Background: Reviews of how doctors and nurses search for online information are relatively rare, particularly where research examines how they decide whether to use Internet‐based resources. Original research into their online searching behaviour is also rare, particularly in real world clinical settings. as is original research into their online searching behaviour. This review collates some of the existing evidence, from 1995 to 2009. Objectives: To establish whether there are any significant differences in the ways and reasons why doctors and nurses seek out online information; to establish how nurses and doctors locate information online; to establish whether any conclusions can be drawn from the existing evidence that might assist health and medical libraries in supporting users. Methods: An initial scoping literature search was carried out on PubMed and CINAHL to identify existing reviews of the subject area and relevant original research between 1995 and 2009. Following refinement, further searches were carried out on Embase (Ovid), LISA and LISTA. Following the initial scoping search, two journals were identified as particularly relevant for further table of contents searching. Articles were exclused where the main focus was on patients searching for information or where the focus was the evaluation of online‐based educational software or tutorials. Articles were included if they were review or meta‐analysis articles, where they reported original research, and where the primary focus of the online search was for participants’ ongoing Continuing Professional Development (CPD). The relevant articles are outlined, with details of numbers of participants, response rates, and the user groups. Results: There appear to be no significant differences between the reasons why doctors and nurses seek online Internet‐based evidence, or the ways in which they locate that evidence. Reasons for searching for information online are broadly the same: primarily patient care and CPD (Continuing Professional Development). The perceived barriers to accessing online information are the same in both groups. There is a lack of awareness of the library as a potential online information enabler. Conclusions: Libraries need to examine their policy and practice to ensure that they facilitate access to online evidence‐based information, particularly where users are geographically remote or based in the community rather than in a hospital setting. Librarians also need to take into account the fact that medical professionals on duty may not be able to take advantage of the academic model of online information research. Further research is recommended into the difference between the idealised academic model of searching and real world practicalities; and how other user groups search, for example patients.  相似文献

ABSTRACT

Citizens, including those living in poor and developing countries, need equitable access to information daily to satisfy their diverse and multiple information needs. In this information age and information economy era, easy and instant access to information and knowledge, which are inevitabilities for socio-economic development, cannot be overemphasised. With rolling out of public libraries even in disadvantaged rural communities due to the library conditional grant in South Africa, the study is aimed at investigating factors influencing the Internet access and use in public libraries in Limpopo. The study adopted a qualitative research approach. The twenty four users of three rural, semi-rural and urban public libraries were selected through convenience sampling. A well-placed government official of the Department of Sport, Arts and Culture was purposively selected. All informants were interviewed face to face to collect data. The study found that, although public libraries studied have networked computers for the Internet access and use, there are many challenges. The officials of the relevant department need to study the recommendations of this study to ensure that the people have digital access in public libraries to mitigate the diverse socio-economic challenges they are facing to improve their lives.  相似文献

Objectives

The aims of this study were to: 1) establish whether infection control professionals (ICPs) who had access to and utilised medical librarian services for evidence‐based medicine (EBM) research perceived this assistance to be useful and 2) to establish whether ICPs who used electronic or hard copy resources for EBM research perceived that those resources had a significant impact on their work.

Methods

Convenience sampling was used to collect quantitative data via a questionnaire. Study participants were members of South‐west and Western chapters of the Association for Professionals in Infection Control and Epidemiology. There were 264 questionnaires distributed in this study; 179 participants completed the questionnaire. The response rate for eligible respondents was 59.5% (157).

Results

Results indicated 56.7% (51) of the ICPs with librarian access reported requesting assistance from their work facility librarian. In reference to locating infection control information, 77.9% (95), 87.3% (124) and 93.3% (138) of ICPs found textbooks, journals and the Internet ‘very useful’ or ‘useful’, respectively.

Conclusion

Study results indicated ICPs who used the assistance of medical librarians and/or hard copy or electronic resources for EBM research perceived such sources to be valuable for obtaining infection control information.  相似文献

This paper identifies the sources and channels of information in the rural areas of Bangladesh and highlights the information flow and access patterns at the village level of Comilla and Chittagong districts in Bangladesh. It proposes some suggestions for effective information services in rural area, as well as a specific model for a Bangladesh Integrated Rural Information System (BD-IRIS) to improve the information system of villagers. This study uses structured interviews through a pilot survey of 20% of the households from each village and information gathered by personal observations and other secondary sources, as well as appropriate statistical methods. A total of 155 responses is included in the study.Existing conditions of information flow and access in this case study indicate that there are problems in access in spite of interpersonal sources and channels of information. Of course, it is important to remember that the low literacy rate in the villages studied and in many similar communities presents many serious barriers. The author recommends establishing a Village Information Center (VIC) to provide integrated and concerted information services, along with an integrated rural information system for the purpose in the villages studies, and more widely, to meet the requirements of all people in villages in Bangladesh. The case study is one of very few studies focusing on the flow and access of information for rural areas of Bangladesh, particularly as regards information sources and channels, system and services. The approach can be replicated in other communities, and the proposed model for future direction to improve information system of village level people of Bangladesh could be modified for use in other countries.  相似文献
