Health care systems increasingly rely on patients' data entry efforts to organize and assist in care delivery through health information exchange.
We sought to determine (1) the variation in burden imposed on parents by data entry efforts across paper-based and computer-based environments, and (2) the impact, if any, of parents' health literacy on the task burden.
We completed a randomized controlled trial of parent-completed data entry tasks. Parents of children with attention deficit hyperactivity disorder (ADHD) were randomized based on the Test of Functional Health Literacy in Adults (TOFHLA) to either a paper-based or computer-based environment for entry of health information on their children. The primary outcome was the National Aeronautics and Space Administration Task Load Index (TLX) total weighted score.
We screened 271 parents: 194 (71.6%) were eligible, and 180 of these (92.8%) constituted the study cohort. We analyzed 90 participants from each arm. Parents who completed information tasks on paper reported a higher task burden than those who worked in the computer environment: mean (SD) TLX scores were 22.8 (20.6) for paper and 16.3 (16.1) for computer. Assignment to the paper environment conferred a significant risk of higher task burden (F(1,178) = 4.05, P = .046). Adequate literacy was associated with lower task burden (decrease in burden score of 1.15 SD, P = .003). After adjusting for relevant child and parent factors, parents' TOFHLA score (beta = -.02, P = .02) and task environment (beta = .31, P = .03) remained significantly associated with task burden.
A tailored computer-based environment provided an improved task experience for data entry compared to the same tasks completed on paper. Health literacy was inversely related to task burden.
医疗保健系统越来越依赖患者的数据录入工作，以通过健康信息交换来组织和协助医疗服务的提供。
我们试图确定（1）纸质和计算机环境下数据录入工作给父母带来的负担差异，以及（2）父母的健康素养对任务负担的影响（如有）。
我们完成了一项由父母完成数据录入任务的随机对照试验。根据成人功能性健康素养测试（TOFHLA），将注意力缺陷多动障碍（ADHD）儿童的父母随机分配到纸质或计算机环境中，以便录入其子女的健康信息。主要结局是美国国家航空航天局任务负荷指数（TLX）的总加权分数。
我们筛查了271名父母：194名（71.6%）符合条件，其中180名（92.8%）构成研究队列。我们分析了每组90名参与者的数据。在纸质环境中完成信息任务的父母报告的任务负担高于在计算机环境中工作的父母：纸质环境下的平均（标准差）TLX分数为22.8（20.6），计算机环境下为16.3（16.1）。被分配到纸质环境会带来任务负担更高的显著风险（F(1,178) = 4.05，P = .046）。具备足够的素养与较低的任务负担相关（负担分数降低1.15个标准差，P = .003）。在对相关的儿童和父母因素进行调整后，父母的TOFHLA分数（β = -.02，P = .02）和任务环境（β = .31，P = .03）仍然与任务负担显著相关。
与在纸质环境中完成相同任务相比，量身定制的计算机环境为数据录入提供了更好的任务体验。健康素养与任务负担呈负相关。
