title: Performance evaluation of ambulatory surgery centres: an efficiency approach.
abstract: This paper evaluates the performance of 198 ambulatory surgery centres (ASCs) operating in the State of Pennsylvania during the fiscal year 2006. Performance is assessed from technical efficiency view using data envelopment analysis (DEA). Multi-input/output model included two inputs: number of operating rooms and labour, and patient surgical visits differentiated by age groups: 0-17, 18-64, 65+ as three outputs. Input oriented models were employed to assess various DEA efficiency models. Results show that about 48 (24%) of ASCs are efficient with a mean efficiency score of 0.60. The results also indicate that appropriate utilization of operating rooms and labour inputs are the main determinants of ASC efficiency.
