A Delphi evaluation of the factors influencing length of stay in Australian hospitals.

Using a modified Delphi method, the factors influencing length of inpatient stay (LOS) were explored. Row/column effects loglinear modelling was used to compare ratings between the first and second rounds, and between the clinical and non-clinical groups. Rating scale modelling was used to classify and determine the relative importance of each factor. Six important and 48 significant determinants of LOS were found, and four unimportant factors were identified. The relationship among these factors and the implications of this study are explored.
