ABSTRACT The Hazard and Near Miss Reporting System (HNMRS) was designed to promote patient safety mindfulness as part of a patient safety curriculum for Advanced Practice Nursing (APN) students. We are extending the functionality of the system beyond reporting to Just-in-Time learning by providing context-specific links to internal and external information resources related to the type of hazard or near miss reported. As part of this process, 55 APN nursing students compared two different interfaces on ease of use and reported their perceptions of usefulness and intention to use the information resources links integrated into the HNMRS. The students demonstrated a significant preference for the Category-based Interface as compared to the Question-based Interface (p<.001). Mean scores for perceptions of usefulness and intention to use the context-specific links in the HNMRS for reference purposes reflected moderate to strong agreement.

    ABSTRACT: Computer systems cannot improve organizational performance if they aren't used. Unfortunately, resistance to end-user systems by managers and professionals is a widespread problem. To better predict, explain, and increase user acceptance, we need to better understand why people accept or reject computers. This research addresses the ability to predict peoples' computer acceptance from a measure of their intentions, and the ability to explain their intentions in terms of their attitudes, subjective norms, perceived usefulness, perceived ease of use, and related variables. In a longitudinal study of 107 users, intentions to use a specific system, measured after a one-hour introduction to the system, were correlated 0.35 with system use 14 weeks later. The intention-usage correlation was 0.63 at the end of this time period. Perceived usefulness strongly influenced peoples' intentions, explaining more than half of the variance in intentions at the end of 14 weeks. Perceived ease of use had a small but significant effect on intentions as well, although this effect subsided over time. Attitudes only partially mediated the effects of these beliefs on intentions. Subjective norms had no effect on intentions. These results suggest the possibility of simple but powerful models of the determinants of user acceptance, with practical value for evaluating systems and guiding managerial interventions aimed at reducing the problem of underutilized computer technology.

    ABSTRACT: The aim of this study was to evaluate hospice providers' attitudes and perceptions regarding videophone technology in settings where the technology was introduced but underutilized. Specifically, the project seeks to provide an in-depth understanding of attitudes and perceptions that may lead to failure of a telehealth implementation in the hospice setting in the context of the technology acceptance model. Two hospice agencies were selected as a purposive sample. Both agencies had acquired videophones that were meant to be integrated into care delivery but ultimately were underutilized or never used. Interviews with staff were conducted over the telephone. The interview guide was constructed to capture staff perceptions and attitudes concerning videophone technology. Interviews were audiotaped and transcribed for content analysis. A total of 17 (n = 17) participants (2 hospice administrators, 1 hospice management staff, 10 nurse case managers, and 4 social workers) were interviewed. Participants found videophones to be useful in hospice care but expressed specific practical challenges, such as lack of equipment reliability, lack of human resources, and lack of clarity pertaining to caregiver eligibility criteria. While perceived usefulness of videophones was high among respondents, practical concerns can be interpreted as lack of perceived ease of use. Findings indicate that the Technology Acceptance Model (TAM) provides a good framework for an understanding of telehealth underutilization. Staff perceived that videophones were useful, but they were discouraged by their perception that the videophones were not reliable or easy to use and by their uncertainty about the cases that they were best suited for. Lessons learned are integrated into a randomized clinical trial currently under development.
