The Drug Burden Index (DBI) is a pharmacological risk assessment tool that measures the total exposure to anticholinergic and sedative medicines, which may impair function in older adults. A computerized clinical decision support system (CCDSS) for DBI has not been previously developed or evaluated.
(a) Develop a CCDSS that calculates and generates reports on DBI; (b) validate the CCDSS for accuracy; and (c) evaluate the CCDSS for use in clinical practice.
The DBI Calculator© application, based on the published formula and Australian registered prescribing information was built and designed using Microsoft Access 2010. Accuracy testing involved the comparison of DBI scores computed manually (gold standard) with those computed using The DBI Calculator© for 25 published medication review case studies. Agreement was measured using Cohen's Kappa statistic. To evaluate the CCDSS application in practice, ten pharmacists completed a performance test and usability survey. Participants were timed performing a DBI calculation with the application for a fictitious patient case. The interface, functionality, clinical applications and user satisfaction of the application were rated using 5-point, Likert-type scales.
Excellent agreement between the manual and CCDSS application was observed (Cohen's Kappa 0.95). In the evaluation phase, the average time (mins:sec ± SD) for participants to complete the task was 7:20 ± 1:45 and the DBI Calculator© was considered useful by 80% of pharmacists for recognizing sedative and anticholinergic medicines in practice.
A reliable CCDSS has been developed to report DBI of older patients taking multiple medications. Future studies should test the utility of The DBI Calculator© in clinical practice.
药物负担指数(DBI)是一种药理学风险评估工具,用于衡量抗胆碱能药物和镇静药物的总暴露量,这可能会损害老年人的功能。此前尚未开发或评估用于DBI的计算机化临床决策支持系统(CCDSS)。
(a)开发一个计算并生成DBI报告的CCDSS;(b)验证CCDSS的准确性;(c)评估CCDSS在临床实践中的应用。
基于已发表的公式和澳大利亚注册处方信息,使用Microsoft Access 2010构建并设计了DBI计算器应用程序。准确性测试包括将25个已发表的药物审查案例研究中手动计算的DBI分数(金标准)与使用DBI计算器计算的分数进行比较。使用Cohen's Kappa统计量来衡量一致性。为了评估CCDSS在实践中的应用,十名药剂师完成了一项性能测试和可用性调查。参与者对一个虚拟患者案例使用该应用程序进行DBI计算的时间进行了记录。使用5点李克特量表对该应用程序的界面、功能、临床应用和用户满意度进行评分。
观察到手动计算和CCDSS应用程序之间具有高度一致性(Cohen's Kappa 0.95)。在评估阶段,参与者完成任务的平均时间(分钟:秒±标准差)为7:20±1:45,80%的药剂师认为DBI计算器在实践中对于识别镇静和抗胆碱能药物很有用。
已开发出一种可靠的CCDSS来报告服用多种药物的老年患者的DBI。未来的研究应测试DBI计算器在临床实践中的效用。
