The rapid development of mobile technologies enables more patients to adopt mobile consultations for health services. Mobile health consultations allow voice consultation, a unique feature differentiating it from general online health consultations. However, how patients derive satisfaction in this context has yet to be well explained. This study draws on the social support theory to examine the relative effects of informational support and emotional support on patient satisfaction and the moderating role of consultation channels (voice vs. textual). Two hundred nineteen valid responses from mobile experiments were collected to test the research model and hypotheses. The results revealed that informational support had a more substantial effect on medical quality satisfaction than emotional support, while the impact of the former on service attitude satisfaction was weaker than that of the latter. Meanwhile, using a voice channel strengthened the positive relationship between informational support and medical quality satisfaction and the positive relationship between emotional support and service attitude satisfaction. This study reasonably explains previously conflicting conclusions and adds brand-new knowledge to patient satisfaction in the mobile-based context. Managers are advised to provide targeted social support and voice channel accessibility to improve mobile consultation.  相似文献

In recent years, the number of online health communities (OHCs) has increased rapidly as more patients seek to access alternate sources of health information and connect with other patients who have similar health concerns. However, insufficient attention has been paid to investigating user identities in OHCs. To address this potential research gap, by elaborating on the communication theory of identity, this study presents a multi-layered framework to analyze the different layers of user identities that are portrayed in OHCs. Through coding analysis, we discovered that the personal-layer identities that appear in OHCs are patients, partners, offspring, parents, friends and relatives, and others. Moreover, a series of detection models for the personal-layer identities of users were developed, which incorporated content features into machine learning approaches, and they achieved F1-scores above 0.88. Furthermore, we analyzed the features of enactment-layer identities presented by users’ posting behavior and content and the impact of the personal-layer identities of users on the features of the enactment-layer identities. The findings suggested that the features of the enactment-layer identities differed significantly among users with diverse personal-layer identities in terms of both behaviors and communication needs. Users who were identified as patients served as both information seekers and providers, whereas users with the personal-layer identities of parents tended to engage in the community continuously. Our findings extend the understanding of user identities within the context of OHCs.  相似文献

This article provides a more differentiated understanding of mobile health consumers, and considers whether health app use may contribute to new digital inequalities. It focuses on factors associated with mobile health app use, and identifies which factors explain the use of different types of health apps. Data from a large representative sample of the Dutch population (N = 1,079) show that mobile health app users were generally younger, higher educated, and had higher levels of e-health literacy skills than non-users. Interestingly, different usage patterns were found for specific types of health apps. Theory and policy implications are discussed.  相似文献

Online health consultation (OHC) serves as an important approach for patients to take an initial impression of a physician's interaction with their patients. However, little study has paid attention to how physicians leverage their interaction performance to attract patients. Drawing on signaling theory and externality effect, this study investigates how a physician's OHC performance influences patients’ choice of consulting the physician in a chronic disease context on an online health platform. By decomposing a physician's interaction performance into three dimensions, i.e., interaction breadth, interaction length, and interaction depth, this paper provides a novel method to evaluate the physician's performance. Information of 4434 physicians from six departments of chronic diseases at 185 general hospitals in the Tier Three Class A segment across China was collected, including individual information and the OHC records of the physicians. Regression analyses were applied to test the hypotheses. The results indicate that better performance in the interaction breadth and length helps physicians attract more patients while higher interaction depth reduces patients’ choice of physician. A physician's general health knowledge sharing behavior and expertise level intensify the negative effect of interaction depth on patient choice of physician. This study contributes to the literature on online health behavior, chronic disease management, and signaling theory, and offers implications for practice.  相似文献

Although more than a million academic papers have been posted on Facebook, there is little detailed research about which fields or cross-field issues are involved and whether there are field or public interest relationships between Facebook mentions and future citations. In response, we identified health and biomedical scientific papers mentioned on Facebook and assigned subjects to them using the MeSH and Science Metrix journal classification schema. Multistage adaptive LASSO and unpenalized least-squares regressions were used to model Facebook mentions by fields and MeSH terms. The fields Science and Technology, General and Internal Medicine, Complementary and Alternative Medicine, and Sport Sciences produced higher Facebook mention counts than average. However, no MeSH cross-field issue differences were found in the rate of attracting Facebook mentions. The relationship between Facebook mentions and citations varies between both fields and MeSH cross-field issues. General and Internal Medicine, Cardiovascular System and Hematology and Developmental Biology have strongest correlations between Facebook mentions and citations, probably due to high citation rates and high Facebook visibility in these areas.  相似文献

Online health interactions (OHIs) can benefit patients, physicians, and society. However, little research has been conducted that studies the social value of OHIs for third-party patients who view previous OHIs concerning similar health issues to theirs. Drawing on the literature on social support and information uncertainty, this study established a theoretical model to explore the roles of treatment information, prevention information, and emotional support in determining information usefulness perceived by third-party patients, and whether such relationships are contingent on information uncertainty. The model was tested using “health questions and answers” textual data from 1,848 OHIs. The results indicate that prevention information and emotional support significantly improve information usefulness perceived by third-party patients. When the level of information uncertainty regarding physicians’ replies is high, the effect of treatment information is strengthened and the effect of emotional support is weakened, indicating both the bright and dark side of information uncertainty. This study has implications for practitioners and contributes to the literature on online health information, social support, information science, and information uncertainty.  相似文献

Nowadays, it is a common practice for healthcare professionals to spread medical knowledge by posting health articles on social media. However, promoting users’ intention to share such articles is challenging because the extent of sharing intention varies in their eHealth literacy (high or low) and the content valence of the article that they are exposed to (positive or negative). This study investigates boundary conditions under which eHealth literacy and content valence help to increase users’ intention to share by introducing a moderating role of confirmation bias—a tendency to prefer information that conforms to their initial beliefs. A 2 (eHealth literacy: high vs. low) × 2 (content valence: positive vs. negative) between-subjects experiment was conducted in a sample of 80 participants. Levels of confirmation bias ranging from extreme negative bias to extreme positive bias among the participants were assessed during the experiment. Results suggested that: (1) users with a high level of eHealth literacy were more likely to share positive health articles when they had extreme confirmation bias; (2) users with a high level of eHealth literacy were more likely to share negative health articles when they had moderate confirmation bias or no confirmation bias; (3) users with a low level of eHealth literacy were more likely to share health articles regardless of positive or negative content valence when they had moderate positive confirmation bias. This study sheds new light on the role of confirmation bias in users’ health information sharing. Also, it offers implications for health information providers who want to increase the visibility of their online health articles: they need to consider readers’ eHealth literacy and confirmation bias when deciding the content valence of the articles.  相似文献

Cyberchondria is conceptualized as excessive online searches for medical information, which is typically accompanied by feelings of emotional distress or anxiety. While previous studies in this nascent area have identified various psychological predictors of cyberchondria, a relative dearth of research has explored the role of different online information sources in its development. Informed by the stimulus-organism-response (SOR) model and the literature on cyberchondria, this study proposes a theoretical framework to explain why people develop cyberchondria when seeking medical information via different online sources. Based on a three-wave panel survey (N = 654), our findings suggest that health information seeking via online search engines increases online information overload (β = 0.11, p = .02), while health information seeking via social media platforms and health-specific websites increases online information trust (β = 0.13, p = .005; β = 0.25, p < .001). Additionally, online information overload is negatively related to online information trust (β = -0.39, p < .001). Subsequently, both online information overload and online information trust trigger cyberchondria (β = 0.73, p < .001; β = 0.15, p < .001). This study can contribute to the literature by expanding and deepening our understanding of cyberchondria developmental trajectory as well as emphasizing the pivotal role of online information sources in this complicated and dynamic process.  相似文献

Inter-organizational knowledge sharing systems (IOKSS) can serve as strategic systems for knowledge-based sectors. Most prior research on inter-organizational systems (IOSs) focuses on organizations’ adoption of such systems; they reveal little about knowledge workers’ adoption of IOS, especially in horizontally linked firms. Knowledge workers’ perception is critical to the deployment of IOKSS at all stages. On the basis of a Delphi technique in the health sector, this study demonstrates that IOKSS can benefit individuals, customers, organizations, the sector, and the knowledge sharing process, and that the challenges of IOKSS arise from individuals, peers, IOKSS, organizations, and the sector.  相似文献

Academic spin-offs often lack business expertise, face uncertainties regarding their innovation and their markets, and do not have a clear idea of how their product will create value. In spite of this vagueness, academic entrepreneurs must articulate a business model and rapidly establish trustworthy relationships with potential users, purchasers and capital investors. One may thus wonder how their technology development process is influenced by the long-term expectations of their putative customers as well as the short-term requirements of capital investors? This longitudinal case study examines how the business models of three Canadian health technology spin-offs sought to address the value expectations of clinical users and capital investors, how tensions were resolved, and the impact this had on technology design. We describe the synergistic readjustments, drastic reconfiguration and mismatch between business model and technology design we observed. Our discussion highlights the mediating mechanisms by which business models and technology design influence each other, clarifying why the initial value proposition of the spin-offs was either refined or reframed. Beyond confirming the importance of differentiating business models in the health technology industry, our study suggests that it is not only who makes decision that matters, but also how stakeholders’ value expectations get embedded in a spin-off's value proposition.  相似文献

Electronic Health Record (EHR) can promote awareness or knowledge about healthcare among patients and healthcare professionals to improve collaboration between different governmental bodies, and enhance healthcare quality. The aim of the study is to identify the critical farctors affecting the physicians’ adoption of EHR in healthcare system of Bangladesh by extending the Unified Theory of Acceptance and Use of Technology (UTAUT) to include Personal Innovativeness in Information Technology and Resistance to Change. A cross-sectional survey questionnaire was used to collect data from 300 participants in different private and public hospitals in Dhaka, the capital city of Bangladesh. The study used partial least square (PLS) method, a statistical analysis technique based on the structural equation modeling (SEM), to analyze the collected data. The results of the study determined that Social Influence (β = 0.19, P < 0.05), Facilitating Conditions (β = 0.19, P < 0.05), and Personal Innovativeness in Information Technology (β = 0.19, P < 0.05) had a significant influence on physicians’ Behavioral Intention to adopt the EHR system, whereas Performance Expectancy (β = 0.08, P > 0.05), Effort Expectancy (β = -0.02, P > 0.05), and Resistance to Change (β = 0.03, P > 0.05) had no significant influence. The findings suggest that policymakers should increase the adoption of the EHR system by developing social strategies to encourage physicians to stimulate each other to use the EHR system and ensuring technical sufficiency, training to facilitate the use of the EHR system. In addition, the policymakers should identify physicians who possess a propensity to experiment with new information technologies as well as reduce existing challenges and barriers such as computers crush, poor infrastructure with erratic power supply etc. Moreover, we identify future research areas that provide scholars opportunities to push theoretical and empirical boundaries and offer further insights into the study of the EHR system.  相似文献

To the keen observer of American political and medical history, a disturbing set of debates surrounded the sanity of free Black residents of the United States of America after the publication of the controversial 1840 census returns on race and insanity. This article analyzes how the census became a battlefield where physicians and other commentators fought over—and thus shaped—various political meanings of Black insanity before and after the American Civil War, up until the 1890s, as the South underwent a massive political and social transformation, from slavery to emancipation. It also highlights the arguments raised by authors such as James McCune Smith and Ramón de la Sagra who attempted to disprove the returns shortly after their publication, and whose arguments contributed to efforts to combat scientific racism.  相似文献
