Large administrative database, or "big data" research studies can include an immense number of patients. Strengths of research based on big data include generalizability resulting from diverse patients, diverse providers, and diverse clinical settings. Limitations of research based on large administrative databases may include indeterminate quality and obscure purpose of data entry, lack of information regarding confounding variables, and suboptimal clinical outcome measures. Thus, research conclusions based on big data must be scrutinized in a discerning and critical manner.
大型管理数据库，或“大数据”研究可以包括大量的患者。基于大数据的研究的优势包括来自不同患者、不同提供者和不同临床环境的可推广性。基于大型管理数据库的研究的局限性可能包括数据录入质量不确定和目的不明确、缺乏关于混杂变量的信息以及临床结局测量不理想。因此，基于大数据的研究结论必须以审慎和批判的态度进行审查。
