Medical Practice Variations in Elective Surgery
The study of variations in elective surgery may be considered a paradigm within the field of medical practice variations. It was the focus of the first seminal work on unwarranted variations where the initial insights and first major hypotheses regarding medical practice variations were based on patterns of variations seen in rates of elective procedures. The taxonomy regarding the underlying causes of variations was largely built upon elective surgery. The current debate on policy implications is populated with numerous examples of elective procedures.
Stemming from work by Glover, Wennberg, Gittelsohn, and McPherson and based on a comprehensive literature review, this chapter is aimed at characterizing variations in elective surgery. The chapter presents the current evidence on variations, describing and interpreting the factors affecting variations in the rates of elective procedures and highlighting lessons expected to have immediate implications for health policy.
