BACKGROUND: Cardiometabolic diseases (CMDs) are a group of interrelated conditions, including heart failure and diabetes, that increase the risk of cardiovascular and metabolic complications. The rising number of Australians with CMDs has necessitated new strategies for those managing these conditions, such as digital health interventions. The effectiveness of digital health interventions in supporting people with CMDs is dependent on the extent to which users engage with the tools. Augmenting digital health interventions with conversational agents, technologies that interact with people using natural language, may enhance engagement because of their human-like attributes. To date, no systematic review has compiled evidence on how design features influence the engagement of conversational agent-enabled interventions supporting people with CMDs. This review seeks to address this gap, thereby guiding developers in creating more engaging and effective tools for CMD management.
OBJECTIVE: The aim of this systematic review is to synthesize evidence pertaining to conversational agent-enabled intervention design features and their impacts on the engagement of people managing CMD.
METHODS: The review is conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and reported in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Searches will be conducted in the Ovid (Medline), Web of Science, and Scopus databases, which will be run again prior to manuscript submission. Inclusion criteria will consist of primary research studies reporting on conversational agent-enabled interventions, including measures of engagement, in adults with CMD. Data extraction will seek to capture the perspectives of people with CMD on the use of conversational agent-enabled interventions. Joanna Briggs Institute critical appraisal tools will be used to evaluate the overall quality of evidence collected.
RESULTS: This review was initiated in May 2023 and was registered with the International Prospective Register of Systematic Reviews (PROSPERO) in June 2023, prior to title and abstract screening. Full-text screening of articles was completed in July 2023 and data extraction began August 2023. Final searches were conducted in April 2024 prior to finalizing the review and the manuscript was submitted for peer review in July 2024.
CONCLUSIONS: This review will synthesize diverse observations pertaining to conversational agent-enabled intervention design features and their impacts on engagement among people with CMDs. These observations can be used to guide the development of more engaging conversational agent-enabled interventions, thereby increasing the likelihood of regular intervention use and improved CMD health outcomes. Additionally, this review will identify gaps in the literature in terms of how engagement is reported, thereby highlighting areas for future exploration and supporting researchers in advancing the understanding of conversational agent-enabled interventions.

In the rapidly evolving landscape of information technologies, individuals and organizations must adapt to the digital age. Given the diversity in users\' knowledge and experience with technology, their acceptance levels also vary. Over the past 30 years, various theoretical models have been introduced to provide a framework for understanding user acceptance of technology. Among these, the Technology Acceptance Model (TAM) stands out as a key theoretical framework, offering insights into why new technologies are either accepted or rejected. Analyzing user acceptance of technology has thus become a critical area of study. Healthcare organizations aim to assess the perceived efficacy and user-friendliness of a given technology. This will help health organisations design and implement HIS that meet users\' needs and preferences. In this context, how does the TAM clarify the acceptance and use of Health Information Systems (HIS)? To address this inquiry, a comprehensive literature review will be carried out. The systematic review involved 29 studies issued between 2018 and 2023 and searched the databases Pubmed, Scopus, Wos and Ulakbim TR Index. The PRISMA flowchart was used to identify the included studies. According to the results, some variables stand out in the acceptance and utilisation of HIS. Among the users of HIS, it can be said that the results relating to nurses stand out. In particular, there are studies which emphasise that \'gender\' is a crucial factor in explaining the models. Another crucial finding of the current systematic review is the need to train users in the acceptance and use of HIS.

Telehealth holds potential for inclusive and cost-saving health care; however, a better understanding of the use and acceptance of telehealth for health promotion among rural older adults is needed. This systematic review aimed to synthesize evidence for telehealth use among rural-living older adults and to explore cost-effectiveness for health systems and patients.
This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study designs reporting health promotion telehealth interventions with rural-living adults aged 55 and older were eligible for review. Following screening and inclusion, articles were quality-rated and ranked by level of evidence. Data extraction was guided by the Technology Acceptance Model and organized into outcomes related to ease of use, usefulness, intention to use, and usage behavior along with cost-effectiveness.
Of 2,247 articles screened, 42 were included. Positive findings for the usefulness of telehealth for promoting rural older adults\' health were reported in 37 studies. Evidence for ease of use and usage behavior was mixed. Five studies examined intention to continue to use telehealth and in 4 of these, patients preferred telehealth. Telehealth was cost-effective for health care delivery (as a process) compared to face to face. However, findings were mixed for cost-effectiveness with both reports of savings (e.g., reduced travel) and increased costs (e.g., insurance).
Telehealth was useful for promoting health among rural-living older adults. Technological supports are needed to improve telehealth ease of use and adherence. Cost-effectiveness of telehealth needs more study, particularly targeting older adults.

Technology acceptance by users has been extensively studied in recent years in various fields such as technologies for learning, e-commerce, and business technologies. This review focuses specifically on Human Resource Information Systems (HRIS) and its acceptance by users. Given their widespread use in organisations, HRIS acceptance has been researched but not synthesised in any way. This article aims to review the effectiveness of the classical TAM and UTAUT models commonly used for new technologies and to identify the variables added to these models to better predict HRIS acceptance by employees. It also highlights the importance of the human-machine-organisation relationship to contribute to the understanding of HRIS acceptance in professional environments. This review confirms the effectiveness of the TAM and UTAUT models and proposes to develop them by (a) variables reffering to technological characteristics (security, system response time, and the data quality implemented in the system), (b) user satisfaction with the system, and (c) organisational variables (expected role of the HR department). The discussion focuses on the retroaction possibilities between the different Human-Machine-Organisation relation levels.

OBJECTIVE: To systematically evaluate the acceptability of high-technology augmentative and alternative communication (high-tech AAC) among ICU patients who are voiceless guided by the technology acceptance model (TAM).
METHODS: We searched the Cochrane Library, EMBASE, PubMed, CINAHL, PsycINFO, Web of Science, SinoMed, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database and Wanfang Database from database inception to September 2019. Studies that examined conscious nonverbal ICU patients with high-tech AAC intervention were included. Two reviewers independently collected and evaluated all the studies. The methodological quality was assessed by using the Joanna Briggs Institute critical appraisal tool.
RESULTS: Eighteen studies with a total of 914 patients met the inclusion criteria, and the quality of the studies varied from low to moderate. Based on the TAM, ICU voiceless patients perceived that high-tech AAC was useful, was easy to use, decreased communication difficulties, reduced negative emotions, and improved symptom identification and management. Patients maintained a positive attitude and were willing to continue to use high-tech AAC.
CONCLUSIONS: Although the existing evidence is limited, voiceless patients regard high-tech AAC devices as a useful, reliable, and acceptable alternative communication choice in the ICU. Multicenter, large-sample, and high-quality studies are highly recommended in the future.
