Abstract
Lean healthcare practice cases can serve as a valuable source of management experience and provide crucial insights for hospitals that are seeking to adopt lean management practices. This paper proposes a method for constructing a lean healthcare contradiction matrix using practice cases, which utilizes the problem-oriented systematic knowledge representation abilities of the TRIZ contradiction matrix. The method involves constructing contradiction pairs based on LDA topic model, constructing a contradiction matrix based on qualitative research and TRIZ theory, and obtaining the text of medical practice cases through the use of web crawling tools. Using LDA topic model, eight parameters were identified. Thirteen principles corresponding to contradiction pairs were obtained using the qualitative research coding analysis method, leading to the establishment of a lean healthcare contradiction matrix. The matrix provides a systematic knowledge retrieval mechanism for lean healthcare treatment and theoretical support for the implementation of lean management in hospitals.
