Pain assessment is a key component of pain management and research in infants. We developed software to assist in coding of pain in infants called PAiN (Pain Assessment in Neonates).
The aims of this study were to evaluate the usability of PAiN in terms of effectiveness, efficiency, and satisfaction among novice and expert users and to compare the efficiency and satisfaction of PAiN to existing software for coding of infant pain among expert users.
A quantitative usability testing approach was conducted with two participant groups, representing novice and expert end-users. Testing included an observed session with each participant completing a pain assessment coding task, followed by administration of the Post Study System Usability Questionnaire and Desirability Toolkit. For comparison, the usability of existing coding software was also evaluated by the expert group.
Twelve novice and six expert users participated. Novice users committed 14 noncritical navigational errors, and experts committed six. For experts, the median time for completing the coding task was 28.6 min in PAiN, compared to 46.5 min using the existing software. The mean Post Study System Usability Questionnaire score among novice (1.89) and expert users (1.40) was not significantly different ( = 0.0917). Among experts, the score for the existing software (4.83) was significantly ( = 0.0277) higher compared to PAiN (1.40). Lower scores indicate more positive responses.
Users were highly satisfied with PAiN. Experts were more efficient with PAiN compared to the existing software. The study was critical to ensuring that PAiN is error free and easy to use prior to implementation.
疼痛评估是婴儿疼痛管理与研究的关键组成部分。我们开发了一款名为PAiN（新生儿疼痛评估）的软件，用于辅助婴儿疼痛编码。
本研究旨在从有效性、效率和满意度方面评估PAiN在新手和专家用户中的可用性，并在专家用户中比较PAiN与现有婴儿疼痛编码软件的效率和满意度。
采用定量可用性测试方法，对代表新手和专家终端用户的两个参与组进行测试。测试包括观察每个参与者完成疼痛评估编码任务的过程，随后进行研究后系统可用性问卷和需求工具包的管理。作为比较，专家组也对现有编码软件的可用性进行了评估。
12名新手用户和6名专家用户参与了研究。新手用户出现了14个非关键导航错误，专家用户出现了6个。对于专家用户来说，使用PAiN完成编码任务的中位数时间为28.6分钟，而使用现有软件为46.5分钟。新手（1.89）和专家用户（1.40）的研究后系统可用性问卷平均得分无显著差异（P = 0.0917）。在专家用户中，现有软件的得分（4.83）显著高于PAiN（1.40）（P = 0.0277）。得分越低表明反应越积极。
用户对PAiN高度满意。与现有软件相比，专家使用PAiN的效率更高。该研究对于确保PAiN在实施前无错误且易于使用至关重要。
