评估以个人数码助理（PDA）为基础的系统收集结核病检测结果的有效性，并将此新系统与以前的纸质系统进行比较。PDA和纸张为基础的系统进行了评估的基础上的处理时间，错误的频率，和工作时间的数据收集器花费。我们在秘鲁的93家卫生机构进行了一项随机分组对照试验。收集19个月的基线数据。然后将地区（n = 4）随机分配到干预（PDA）或对照（纸张）组，并收集6个月的进一步数据。干预和控制区之间进行了比较，并在区内之前和之后的干预措施。基于PDA的系统对处理时间（p < 0.001）和错误（p = 0.005）有显著影响。在地区之间的比较中，培养的中位处理时间从23天减少到8天，涂片的中位处理时间从25天减少到12天。相比之下，延迟>90天的培养物比例从9.2%降至0.1%，错误数量减少了57.1%。该干预措施将处理结果所需的工作时间减少了70%，受到所有用户的青睐。一个设计良好的基于PDA的系统，从一个大的，资源贫乏的地区的机构收集数据，可以显着减少延迟，错误和处理数据所花费的工时。
To evaluate the effectiveness of a personal digital assistant (PDA)-based system for collecting tuberculosis test results and to compare this new system to the previous paper-based system. The PDA- and paper-based systems were evaluated based on processing times, frequency of errors, and number of work-hours expended by data collectors. We conducted a cluster randomized controlled trial in 93 health establishments in Peru. Baseline data were collected for 19 months. Districts (n = 4) were then randomly assigned to intervention (PDA) or control (paper) groups, and further data were collected for 6 months. Comparisons were made between intervention and control districts and within-districts before and after the introduction of the intervention. The PDA-based system had a significant effect on processing times (p < 0.001) and errors (p = 0.005). In the between-districts comparison, the median processing time for cultures was reduced from 23 to 8 days and for smears was reduced from 25 to 12 days. In that comparison, the proportion of cultures with delays >90 days was reduced from 9.2% to 0.1% and the number of errors was decreased by 57.1%. The intervention reduced the work-hours necessary to process results by 70% and was preferred by all users. A well-designed PDA-based system to collect data from institutions over a large, resource-poor area can significantly reduce delays, errors, and person-hours spent processing data.
