The Technology Acceptance Model (TAM) and Unified Theory of Acceptance and Use of Technology (UTAUT) have been used widely in studies of health information technology (HIT) implementation. However, TAM and UTAUT have also been criticized for being overly simplistic (TAM) and for taking a narrow perspective, which focuses only on individual adopters’ beliefs, perceptions and usage intention. Furthermore, with thousands of studies using these theories, their contribution to knowledge has reached a plateau. In this commentary, we discuss some of the criticism of TAM and UTAUT, and argue that biomedical informatics research would benefit from shifting attention from these theories to multi-dimensional approaches that can better capture the complexity of issues surrounding implementation and use of HIT. We propose a number of future undertakings which, in our opinion, are more likely to move the field forward.

技术接受模型（TAM）和技术接受与使用统一理论（UTAUT）已广泛用于健康信息技术（HIT）实施的研究中。但是，TAM和UTAUT也被批评为过于简单化（TAM）并采取狭narrow的视角，这种视角仅着眼于个人采用者的信念，看法和使用意图。此外，随着使用这些理论的数千项研究，它们对知识的贡献达到了平稳状态。在这篇评论中，我们讨论了对TAM和UTAUT的一些批评，并认为生物医学信息学研究将受益于将注意力从这些理论转移到多维方法，这些方法可以更好地把握HIT的实施和使用问题的复杂性。我们提出了一些未来的承诺，
