Identification of factors contributing to increased length of stay in two Diagnosis Related Groups

Abstract

This paper discusses a study conducted to identify factors that contributed to increased length of stay for two diagnosis related groups (DRGs) and their consequential impact on nursing salaries, The study shows that three separate clusters of cost drivers (DRG-related, nurse-related, and patient-related) contributed to increased length of stay for DRG 177 (chronic obstructive airways disease) and DRG 367 (cholecystectomy without exploration of the common bile duct). It was not possible to establish a link between length of stay and nursing salaries due to lack of relevant data. The results of the study can be used to raise professional awareness to the difficulties encountered by nurse managers in controlling length of stay when there are substantial numbers of different DRGs in acute care wards. The results can also be used as a basis for conducting larger studies into DRGs with higher than expected lengths of stay.
