This systematic review of mixed methods studies focuses on factors that can facilitate or limit the implementation of information
and communication technologies (ICTs) in clinical settings. Systematic searches of relevant bibliographic databases identified
studies about interventions promoting ICT adoption by healthcare professionals. Content analysis was performed by two reviewers
using a specific grid. One hundred and one (101) studies were included in the review. Perception of the benefits of the innovation
(system usefulness) was the most common facilitating factor, followed by ease of use. Issues regarding design, technical concerns,
familiarity with ICT, and time were the most frequent limiting factors identified. Our results suggest strategies that could
effectively promote the successful adoption of ICT in healthcare professional practices. 相似文献

Many studies have examined the integration of information systems into healthcare institutions, leading to several standards in the healthcare domain (CORBAmed: Common Object Request Broker Architecture in Medicine; HL7: Health Level Seven International; DICOM: Digital Imaging and Communications in Medicine; and IHE: Integrating the Healthcare Enterprise). Due to the existence of a wide diversity of heterogeneous systems, three essential factors are necessary to fully integrate a system: data, functions and workflow. However, most of the previous studies have dealt with only one or two of these factors and this makes the system integration unsatisfactory. In this paper, we propose a flexible, scalable architecture for Hospital Information Systems (HIS). Our main purpose is to provide a practical solution to insure HIS interoperability so that healthcare institutions can communicate without being obliged to change their local information systems and without altering the tasks of the healthcare professionals. Our architecture is a mediation architecture with 3 levels: 1) a database level, 2) a middleware level and 3) a user interface level. The mediation is based on two central components: the Mediator and the Adapter. Using the XML format allows us to establish a structured, secured exchange of healthcare data. The notion of medical ontology is introduced to solve semantic conflicts and to unify the language used for the exchange. Our mediation architecture provides an effective, promising model that promotes the integration of hospital information systems that are autonomous, heterogeneous, semantically interoperable and platform-independent. 相似文献

Information and Communication Technology (ICT) and Organizational Innovation (OI) are seen as the miracle of post-modernity
in organizations. In this way, they are supposed to resolve most organizational problems, efficiently and rapidly. OI is highly
dependent on the capacity and the investment in knowledge management (internal and external) to support decision making process
and to implement significant changes. We know what explains ICT utilization (ICTU) and what determines OI development (OID)
in healthcare services. Moreover, the literature tends to link ICTU to OID and vice versa. However, this dependency has never
been explored empirically through the lens of roles combination. To identify the existing combined roles profiles of ICTU
and OID among healthcare decision makers and determine factors of the shift from a profile to another. We did the following:
(1) a structured review of the literature on healthcare management by focusing on ICTU and OID which allowed us to build two
indexes and a comprehensive framework; (2) a copula methodology to identify with high precision the thresholds for ICTU and
OID; and (3) a cross-sectional study based on a survey done with a sample of 942 decision makers from Canadian healthcare
organizations through a multinomial logit model to identify determinants of the shift. ICTU and OID are correlated at 22%
(Kendal’s Tau). The joint distribution (combination) of ICTU and OID shows that four major profiles exist among decision makers
in Canadian healthcare organizations: the traditional decision maker, the innovative decision maker, the technologic decision
maker and the contemporary decision maker. We found out that classic factors act as barriers to the shift from one profile
to the desired profile (from 1 to 4, from 2 to 4 and from 3 to 4). We have identified that the attitude toward research and
relational capital are transversal barriers of shift. We have also found that some factors have a specific impact such as
engaging in activities of research acquisition, the administrative position (being a manager), the preference for applied
research results as source of information, the degree of novelty of research results, and the gender. Modern Canadian healthcare
organizations need contemporary decision makers who use ICT and develop OI, if performance is the target. Our results let
us suggest that the isolated administrative agents profile is no more effective in a dynamic and changing world. Contemporary
decision makers need to be more active intellectually and to take risks in their decisions. Relying exclusively on research
results and on their social network is no more helpful for a real shift. Moreover, the traditional factors, i.e. organization
size, time, experience…are no more effective, especially when we consider combined roles. We propose some practical and theoretical
recommendations to support these changes. 相似文献

Many existing healthcare information systems are composed of a number of heterogeneous systems and face the important issue
of system scalability. This paper first describes the comprehensive healthcare information systems used in National Taiwan
University Hospital (NTUH) and then presents a service-oriented architecture (SOA)-based healthcare information system (HIS)
based on the service standard HL7. The proposed architecture focuses on system scalability, in terms of both hardware and
software. Moreover, we describe how scalability is implemented in rightsizing, service groups, databases, and hardware scalability.
Although SOA-based systems sometimes display poor performance, through a performance evaluation of our HIS based on SOA, the
average response time for outpatient, inpatient, and emergency HL7Central systems are 0.035, 0.04, and 0.036 s, respectively.
The outpatient, inpatient, and emergency WebUI average response times are 0.79, 1.25, and 0.82 s. The scalability of the rightsizing
project and our evaluation results show that the SOA HIS we propose provides evidence that SOA can provide system scalability
and sustainability in a highly demanding healthcare information system. 相似文献

This research study evaluates the selection process of a Hospital Information System (HIS), focusing on the level of compromise required by healthcare professionals during said process and the level of satisfaction achieved with the system selected. How other variables, such as job title, length of experience in the healthcare, data processing, and information systems fields affect these measured levels are also evaluated. Results of this study indicate that a HIS is critical to the viability of a hospital's operation and the level of compromises made during the selection process have an impact upon the how satisfied the healthcare provider is with the HIS they select. 相似文献

The security effectiveness based on users’ behaviors is becoming a top priority of Health Information System (HIS). In the first step of this study, through the review of previous studies ‘Self-efficacy in Information Security’ (SEIS) and ‘Security Competency’ (SCMP) were identified as the important factors to transforming HIS users to the first line of defense in the security. Subsequently, a conceptual model was proposed taking into mentioned factors for HIS security effectiveness. Then, this quantitative study used the structural equation modeling to examine the proposed model based on survey data collected from a sample of 263 HIS users from eight hospitals in Iran. The result shows that SEIS is one of the important factors to cultivate of good end users’ behaviors toward HIS security effectiveness. However SCMP appears a feasible alternative to providing SEIS. This study also confirms the mediation effects of SEIS on the relationship between SCMP and HIS security effectiveness. The results of this research paper can be used by HIS and IT managers to implement their information security process more effectively. 相似文献

Although health data standards are perceived to be the essential solution for interoperability barriers within medical IT systems, the level of adoption of those standards still remains frustratingly low. Little is known about the barriers facing their adoption within the healthcare organizations context. In addressing this gap in the literature, based on IT related standards adoption theories such as Diffusion of Innovation Theory and the theories surrounding the Economics of Standards, a qualitative multiple-case study was undertaken in Saudi Arabia to investigate those barriers. The results exposed that few standards were adopted because of four broad reasons, managerial, technical, educational and governmental. While some of the findings can be rooted to those related standards theories, others can be underpinned through the normative literature. Core barriers are the lack of a national regulator and a data exchange plan, and the lack of an adequate policy regarding medical IT systems and information management and national healthcare system; also important are technical barriers and the switching costs to the standards. The outcome of this study can be used in forming effective interventions when planning to use health data standards and, in particular those in developing countries. 相似文献

Healthcare information systems (HISs) are often implemented to enhance the quality of care and the degree to which it is patient-centered,
as well as to improve the efficiency and safety of services. However, the outcomes of HIS implementations have not met expectations.
We set out to organize the knowledge gained in qualitative studies performed in association with HIS implementations and to
use this knowledge to outline an updated structure for implementation planning. A multi-disciplinary team performed the analyses
in order to cover as many aspects of the primary studies as possible. We found that merely implementing an HIS will not automatically
increase organizational efficiency. Strategic, tactical, and operational actions have to be taken into consideration, including
management involvement, integration in healthcare workflow, establishing compatibility between software and hardware and,
most importantly, user involvement, education and training. The results should be interpreted as a high-order scheme, and
not a predictive theory. 相似文献

High-speed information and communication technology (ICT) networks stretch all over Japan. However, their utility in facilitating rural healthcare remains uncharacterized. A nationwide questionnaire survey was sent by mail to 1,018 rural clinics constructed in a public manner in municipalities throughout Japan. ICT use was classified by type, including a doctor-to-doctor manner. Only 19% of the 303 clinics surveyed (with a response rate of 30%) used ICT. Specifically, 50% used it in a doctor-to-doctor manner, while 35% used it to obtain electronic medical records. Differences in proficiency levels among ICT users were cited by 21% of the respondents as a major problem associated with ICT use. In Japan, the prevalence of ICT use for rural healthcare appeared low. We suggest a policy reform to facilitate ICT use in rural healthcare. 相似文献

This article provides a conceptual model for benchmarking the use of clinical information systems within healthcare organizations.
Additionally, it addresses the benefits of clinical information systems which include the reduction of errors, improvement
in clinical decision-making and real time access to patient information. The literature suggests that clinical information
systems provide financial benefits due to cost-savings from improved efficiency and reduction of errors. As a result, healthcare
organizations should adopt such clinical information systems to improve quality of care and stay competitive in the marketplace.
Our research clearly documents the increased adoption of electronic medical records in U.S. hospitals from 2005 to 2007. This
is important because the electronic medical record provides an opportunity for integration of patient information and improvements
in efficiency and quality of care across a wide range of patient populations. This was supported by recent federal initiatives
such as the establishment of the Office of the National Coordinator of Health Information Technology (ONCHIT) to create an
interoperable health information infrastructure. Potential barriers to the implementation of health information technology
include cost, a lack of financial incentives for providers, and a need for interoperable systems. As a result, future government
involvement and leadership may serve to accelerate widespread adoption of interoperable clinical information systems. 相似文献

Precision medicine can revolutionize health care by tailoring treatments to individual patient needs. Advancing precision medicine requires evidence development through research that combines needed data, including clinical data, at an unprecedented scale. Widespread adoption of health information technology (IT) has made digital clinical data broadly available. These data and information systems must evolve to support precision medicine research and delivery. Specifically, relevant health IT data, infrastructure, clinical integration, and policy needs must be addressed. This article outlines those needs and describes work the Office of the National Coordinator for Health Information Technology is leading to improve health IT through pilot projects and standards and policy development. The Office of the National Coordinator for Health Information Technology will build on these efforts and continue to coordinate with other key stakeholders to achieve the vision of precision medicine. Advancement of precision medicine will require ongoing, collaborative health IT policy and technical initiatives that advance discovery and transform healthcare delivery. 相似文献

Industry predictions focus on future e-hospitals that will integrate all stakeholders into a seamless network, allowing data to be shared. The Health Level Seven (HL7) is a standard for the interchange of data within the healthcare industry. It simplifies communication interfaces and allows the interoperability among heterogeneous applications. Although the benefits of adopting HL7 are well known, only a few hospitals in Taiwan have actually adopted it. What are the reasons behind the hospitals’ lack of intention to adopt HL7? Most prior studies on HL7 have focused on technical issues and general overlooked the managerial side. This has caused a lack of understanding of factors influencing hospitals’ decision on HL7 adoption. In fact, main reasons behind a hospital’s decision on whether to adopt an innovative technology are more often related to organizational than purely technical issues. Hence, we pay our attention to these organizational considerations over HL7 adoption. Based on the Innovation Diffusion Theory, we proposed a research model to explore the critical factors influencing Taiwan hospitals’ adoption intention of HL7. 472 questionnaires were distributed to all accredited hospitals in Taiwan and 122 were returned. The valid response rate was 25.21% (119). Factor analysis, logistic regression and Pearson Chi-square test were conducted to verify the research model. The results showed that environmental pressure, top management attitude towards HL7, staff’s technology capability, system integrity, and hospital’s scale were critical factors influencing hospitals’ intention on whether to adopt HL7. The research findings provided the government, the healthcare industry, the hospital administrators and the academia with practical and theoretical references. These factors should be considered in planning promotion plan to encourage hospital adoption of HL7. This study also opens up a new research direction as well as a new viewpoint, and consequentially improves the completeness of related researches in the medical informatics discipline. 相似文献

While much attention has been paid to the short-term impact that widespread adoption of health information technology (health IT) will have on the healthcare system, there is a corresponding need to look at the long-term effects that extant policies may have on health IT system resilience, innovation, and related ethical, social/legal issues. The American Medical Informatics Association's 2010 Health Policy Conference was convened to further the national discourse on the issues surrounding these longer-term considerations. Conference participants self-selected into three broad categories: resilience in healthcare and health IT; ethical, legal, and social challenges; and innovation, adoption, and sustainability. The discussions about problem areas lead to findings focusing on the lack of encouragement for long-term IT innovation that may result from current health IT policies; the potential impact of uneven adoption of health IT based on the exclusions of the current financial incentives; the weaknesses of contingency and risk mitigation planning that threaten system resilience; and evolving standards developed in response to challenges relating to the security, integrity, and availability of electronic health information. This paper discusses these findings and also offers recommendations that address the interwoven topics of innovation, resilience, and adoption. The goal of this paper is to encourage public and private sector organizations that have a role in shaping health information policy to increase attention to developing a national strategy that assures that health IT innovation and resilience are not impeded by shorter-term efforts to implement current approaches emphasizing adoption and meaningful use of electronic health records. 相似文献

The purpose of this review is to consolidate existing evidence from published systematic reviews on health information system (HIS) evaluation studies to inform HIS practice and research. Fifty reviews published during 1994–2008 were selected for meta-level synthesis. These reviews covered five areas: medication management, preventive care, health conditions, data quality, and care process/outcome. After reconciliation for duplicates, 1276 HIS studies were arrived at as the non-overlapping corpus. On the basis of a subset of 287 controlled HIS studies, there is some evidence for improved quality of care, but in varying degrees across topic areas. For instance, 31/43 (72%) controlled HIS studies had positive results using preventive care reminders, mostly through guideline adherence such as immunization and health screening. Key factors that influence HIS success included having in-house systems, developers as users, integrated decision support and benchmark practices, and addressing such contextual issues as provider knowledge and perception, incentives, and legislation/policy. 相似文献

One of the major problems in health care system integration is the formidable cost of mediating between myriad vendors and
policy makers for updating existing heterogeneous systems to support a great variety of standards or interfaces. To provide
cost-effective healthcare system integration solution, this paper presents a Graphical User Interface state model (GUISM)
for automatically exchanging information with existing healthcare software through their GUIs with no modifications needed
to them. This can save the huge cost of upgrading, testing and redeploying the existing systems. By using the GUISM model,
distributed agents are deployed to the client computers interacting with the local electronic medical system (EMR) for communicating
with other EMR systems. The whole system is called virtual EMR system and each client in this system can request needed patient
healthcare information without knowing the actual location of the data. 相似文献

Prior researches have indicated that an appropriate adoption of information technology (IT) can help hospitals significantly improve services and operations. Radio Frequency Identification (RFID) is believed to be the next generation innovation technology for automatic data collection and asset/people tracking. Based on the Technology–Organization–Environment (TOE) framework, this study investigated high-level managers’ considerations for RFID adoption in hospitals. This research reviewed literature related IT adoption in business and followed the results of a preliminary survey with 37 practical experts in hospitals to theorize a model for the RFID adoption in hospitals. Through a field survey of 102 hospitals and hypotheses testing, this research identified key factors influencing RFID adoption. Follow-up in-depth interviews with three high-level managers of IS department from three case hospitals respectively also presented an insight into the decision of RFID’s adoption. Based on the research findings, cost, ubiquity, compatibility, security and privacy risk, top management support, hospital scale, financial readiness and government policy were concluded to be the key factors influencing RFID adoption in hospitals. For practitioners, this study provided a comprehensive overview of government policies able to promote the technology, while helping the RFID solution providers understand how to reduce the IT barriers in order to enhance hospitals’ willingness to adopt RFID. 相似文献
