RBApp is an educational software program that calculates the biologically effective dose and equivalent dose in 2-Gy fractions, permitting conversion between dose-fractionation schemes in radiation therapy. The purposes of this study were to describe the adoption and current patterns of use of this tool and evaluate user satisfaction with RBApp.
RBApp is available as a native app for Android and BlackBerry and a web app for iOS and other devices. User and device characteristics were collected from app store dashboards and server logs; expected values were retrieved from StatCounter Global Stats. A voluntary web-based questionnaire was created to evaluate the patterns of use of RBApp. This questionnaire collected information on user demographics, purpose of use, and user satisfaction.
Over a 2.75-year period, there were 2,291 installations on Android and BlackBerry devices; 8,074 unique visits were logged to the web app; and 25 respondents completed the web-based questionnaire. Among this group, RBApp was used by radiation oncologists (44.0%), physicists (32.0%), and resident physicians (24.0%). It was used for clinical decision making by 78.3% of users, education and training by 43.5%, and research by 30.4%. Twenty of 22 users (90.9%) were satisfied with RBApp. A greater proportion of web app users used obsolete software to access the application compared with the rest of the global Internet population; 15.2% (95% confidence interval, 12.3%-18.6%) used Windows XP, and 16.0% (95% confidence interval, 13.0%-19.5%) used Internet Explorer 8.0 (expected global proportions 8.5% and 3.1%, respectively).
In this study, a mobile application for radiobiology calculations and its adoption by the radiation oncology community was evaluated. Users were satisfied with RBApp, and this tool is used for both clinical decision making and educational purposes. However, legacy software use remained prevalent, which may have implications for information security.
RBApp是一款教育软件程序，可计算2戈瑞分次剂量下的生物有效剂量和当量剂量，允许在放射治疗的剂量分割方案之间进行转换。本研究的目的是描述该工具的采用情况和当前使用模式，并评估用户对RBApp的满意度。
RBApp有适用于安卓和黑莓系统的原生应用程序，以及适用于iOS和其他设备的网络应用程序。用户和设备特征从应用商店仪表板和服务器日志中收集；预期值从StatCounter全球统计数据中获取。创建了一份基于网络的自愿调查问卷，以评估RBApp的使用模式。该问卷收集了用户人口统计学、使用目的和用户满意度方面的信息。
在2.75年的时间里，安卓和黑莓设备上有2291次安装；网络应用程序有8074次独立访问记录；25名受访者完成了基于网络的调查问卷。在这一组中，放射肿瘤学家（44.0%）、物理学家（32.0%）和住院医师（24.0%）使用了RBApp。78.3%的用户将其用于临床决策，43.5%用于教育和培训，30.4%用于研究。22名用户中有20名（90.9%）对RBApp感到满意。与全球互联网其他用户相比，使用过时软件访问该应用程序的网络应用程序用户比例更高；15.2%（95%置信区间，12.3%-18.6%）使用Windows XP，16.0%（95%置信区间，13.0%-19.5%）使用Internet Explorer 8.0（全球预期比例分别为8.5%和3.1%）。
在本研究中，对一款用于放射生物学计算的移动应用程序及其在放射肿瘤学界的采用情况进行了评估。用户对RBApp感到满意，该工具用于临床决策和教育目的。然而，旧软件的使用仍然很普遍，这可能对信息安全有影响。
