Characterization of Major Surgery Performed on an Outpatient Basis at a Basic General Hospital

Abstract

Background: to assess the outpatient surgery units of the recently-opened Algeciras Hospital based on the customary system of payment in other countries, the Related Diagnostic Groups (RDG’s). Methods: Descriptive study regarding 3,051 surgical procedures performed on a scheduled basis in 1997 (not including the minor surgery using a local anesthetic), using as a source of information the minimum basic set of data for hospital discharge, obtaining and analyzing the RDG’s. The hospital stays avoided based on the average stay of those patients admitted for the same RDG within the time period under study have been calculated. Results: Major surgery performed on an outpatient basis afforded the possibility of an overall replacement percentage of 50.4% (33.3% of all of the patients who underwent surgery on a scheduled basis, that is, 4.1% of all of this Hospital’s admissions), which meant an savings of 2,112 hospital stays. The most frequent RDG’s having the greatest impact on stays avoided were the surgical procedures performed on the crystalline lens and the scraping or conization procedures performed for reasons other than malignant neoplasia. The readmission rate was 1.5%. Conclusions: The overall replacement rate obtained by this major outpatient surgery unit is considered to be acceptable, although it must increase within the next few years. We found differences in the spread of the processes dealt with as compared to other units in our environment, this being explainable due to the difficulties involved in starting up surgery of these characteristics.
