A wide variety of risk calculators estimate individuals' risk for HIV/sexually transmitted infections (STI) online. These tools can help target HIV/STI screening and optimize clinical decision-making. Yet, little evidence exists on suitable features for these tools to be acceptable to end-users. We investigated the desirable characteristics of risk calculators among STI clinic clients and testing service providers. Participants interacted with online HIV/STI risk calculators featuring varied target audiences, completion lengths, and message outputs. Thematic analysis of focus groups identified six qualities that would make risk calculators more appealing for online client use: providing personalized risk assessments based on users' specific sexual behaviors and HIV/STI-related concerns; incorporating nuanced risk assessment and tailored educational information; supplying quantifiable risk estimates; using non-stigmatizing and inclusive framing; including explanations and next steps; and developing effective and appropriate branding. Incorporating these features in the design of online HIV/STI risk calculators may improve their acceptability among end-users.

“迷你拨号护士”和“好品牌”：在线HIV / STI风险计算器的理想功能是什么？

各种各样的风险计算器可以在线估算个人感染HIV /性传播感染（STI）的风险。这些工具可以帮助针对HIV / STI筛查并优化临床决策。但是，很少有证据表明这些工具的适当功能可以为最终用户所接受。我们调查了STI诊所客户和测试服务提供商中风险计算器的理想特性。参加者与具有不同目标受众，完成时长和消息输出的在线HIV / STI风险计算器进行了交互。对焦点小组的主题分析确定了六种质量，这将使风险计算器对于在线客户的使用更具吸引力：根据用户的特定性行为和与HIV / STI相关的关注提供个性化的风险评估；纳入细微的风险评估和量身定制的教育信息；提供可量化的风险估计；使用非污名化和包容性框架；包括说明和后续步骤；并开发有效和适当的品牌。将这些功能整合到在线HIV / STI风险计算器的设计中可能会提高最终用户的接受度。
