BACKGROUND: There is an increased number of web-based tools designed for people with dementia and their family caregivers and addressing communication and decision-making. The loss of cognitive functions associated with dementia can impact individuals\' experiences and use of web-based tools. There is a need for high quality and user-friendly web-based tools that support communication and decision-making for people with dementia and their family caregivers.
OBJECTIVE: To identify usability requirements, usability testing methods, and design suggestions from studies focusing on web-based tools for communication and decision-making support in dementia care.
METHODS: We conducted a systematic review with narrative synthesis. Five databases were systematically searched in February 2023. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool.
RESULTS: A total of 1,032 articles were identified and 7 fulfilled inclusion criteria. Web-based tools addressed technology usage, health promotion, home modification information, shared decision-making facilitation, information needs and social isolation. Methods to test usability included surveys, interviews, focus groups, cognitive walkthroughs and think-aloud procedures. Findings suggested reducing cognitive load, enhancing readability, providing clear language, and emphasising the need for additional support for people with dementia. Design recommendations include optimising information delivery and presentation, enhancing visual elements, streamlining navigation, providing concrete examples, using clear language, and offering training and tailored support.
CONCLUSIONS: Usability requirements ranged from visual appearance and navigation to delivery of content and support needed. This review contributes to efforts to improve design and development of web-based tools targeting communication and decision-making in dementia care. Further research should address tailored support to enhance usability for people with dementia.

There is an increasing number of interactive web-based advance care planning (ACP) support tools, which are web-based aids in any format encouraging reflection, communication, and processing of publicly available information, most of which cannot be found in the peer-reviewed literature.
This study aims to conduct a systematic review of web-based ACP support tools to describe the characteristics, readability, and quality of content and investigate whether and how they are evaluated.
We systematically searched the web-based gray literature databases OpenGrey, ClinicalTrials.gov, ProQuest, British Library, Grey Literature in the Netherlands, and Health Services Research Projects in Progress, as well as Google and app stores, and consulted experts using the following eligibility criteria: web-based, designed for the general population, accessible to everyone, interactive (encouraging reflection, communication, and processing of information), and in English or Dutch. The quality of content was evaluated using the Quality Evaluation Scoring Tool (score 0-28-a higher score indicates better quality). To synthesize the characteristics of the ACP tools, readability and quality of content, and whether and how they were evaluated, we used 4 data extraction tables.
A total of 30 tools met the eligibility criteria, including 15 (50%) websites, 10 (33%) web-based portals, 3 (10%) apps, and 2 (7%) with a combination of formats. Of the 30 tools, 24 (80%) mentioned a clear aim, including 7 (23%) that supported reflection or communication, 8 (27%) that supported people in making decisions, 7 (23%) that provided support to document decisions, and 2 (7%) that aimed to achieve all these aims. Of the 30 tools, 7 (23%) provided information on the development, all of which were developed in collaboration with health care professionals, and 3 (10%) with end users. Quality scores ranged between 11 and 28, with most of the lower-scoring tools not referring to information sources.
A variety of ACP support tools are available on the web, varying in the quality of content. In the future, users should be involved in the development process of ACP support tools, and the content should be substantiated by scientific evidence.

Web-based personalized predictive tools in orthopedic surgery are becoming more widely available. Despite rising numbers of these tools, many orthopedic surgeons may not know what tools are available, how these tools were developed, and how they can be utilized. The aim of this scoping review is to compile and synthesize the profile of existing web-based orthopedic tools. We conducted two separate PubMed searches-one a broad search and the second a more targeted one involving high impact journals-with the aim of comprehensively identifying all existing tools. These articles were then screened for functional tool URLs, methods regarding the tool\'s creation, and general inputs and outputs required for the tool to function. We identified 57 articles, which yielded 31 unique web-based tools. These tools involved various orthopedic conditions (e.g., fractures, osteoarthritis, musculoskeletal neoplasias); interventions (e.g., fracture fixation, total joint arthroplasty); outcomes (e.g., mortality, clinical outcomes). This scoping review highlights the availability and utility of a vast array of web-based personalized predictive tools for orthopedic surgeons. Increased awareness and access to these tools may allow for better decision support, surgical planning, post-operative expectation management, and improved shared decision-making.
