New discoveries in basic science are creating extraordinary opportunities to design novel biomedical preventions and therapeutics for human disease. But the clinical evaluation of these new interventions is, in many instances, being hindered by a variety of legal, regulatory, policy and operational factors, few of which enhance research quality, the safety of study participants or research ethics. With the goal of helping increase the efficiency and effectiveness of clinical research, we have examined how the integration of utilization-focused evaluation with elements of business process modeling can reveal opportunities for systematic improvements in clinical research. Using data from the NIH global HIV/AIDS clinical trials networks, we analyzed the absolute and relative times required to traverse defined phases associated with specific activities within the clinical protocol lifecycle. Using simple median duration and Kaplan-Meyer survival analysis, we show how such time-based analyses can provide a rationale for the prioritization of research process analysis and re-engineering, as well as a means for statistically assessing the impact of policy modifications, resource utilization, re-engineered processes and best practices. Successfully applied, this approach can help researchers be more efficient in capitalizing on new science to speed the development of improved interventions for human disease.
基础科学领域的新发现为设计针对人类疾病的新型生物医学预防和治疗方法创造了绝佳机会。但在许多情况下,这些新干预措施的临床评估受到各种法律、监管、政策和操作因素的阻碍,其中很少有因素能提高研究质量、研究参与者的安全性或研究伦理。为了提高临床研究的效率和效果,我们研究了以利用为重点的评估与业务流程建模要素的整合如何能揭示临床研究系统改进的机会。利用美国国立卫生研究院全球艾滋病毒/艾滋病临床试验网络的数据,我们分析了在临床方案生命周期内与特定活动相关的规定阶段所需的绝对时间和相对时间。通过简单的中位数持续时间和卡普兰 - 迈耶生存分析,我们展示了这种基于时间的分析如何能为研究过程分析和重新设计的优先级提供依据,以及如何从统计学角度评估政策修改、资源利用、重新设计的流程和最佳实践的影响。成功应用这种方法可以帮助研究人员更有效地利用新科学成果,加速开发针对人类疾病的改进干预措施。
