Abstract

Cholecystectomy is among the most frequent procedures in general surgery. In the healthcare facility organization, it is important to evaluate all interventions and procedures that have a great impact on health management and that have a clear effect on the Length of Stay (LOS). The LOS represents, in fact, an indicator of performance and measure the goodness of a health process. This study was conducted with the aim of providing LOS for all patients undergoing cholecystectomy at the "A.O.R.N. A. Cardarelli" of Naples. Data were collected in the two years 2019 and 2020 and included 650 patients. A MLR model is created in the work to predict the value of LOS as a function of the following variables: gender, age, pre-operative LOS, presence of comorbidities and complication during surgery. The results obtained are as follows: R=0.941 and R2=0.885.

Keywords: Cholecystectomy; Length of Stay; Multiple Regression Model.
