Hospitals’ bed productivity has a remarkable effect on health system performance. The Pabon Lasso Model (PLM) is a useful tool for evaluation of inpatient beds performance and there is a growing trend in use of this technique in hospital performance evaluation. The aim of this study is to review the literature on PLM to gain insight into quality the results of these studies. By adopting a systematic review style, the full text of a total of 29 documents on the topic was reviewed. While in 81.3% (n=26) of the documents Pabon Lasso diagram has been represented complete and correctly, the results of a large fraction of the reviewed studies (59.6%) was limited to identifying the status of the hospitals in question the Pabon Lasso chart, without further analysis of the chart in the context of hospital resources. Our study hence recommends that future studies can draw further useful implications from the PLM model by focusing more on the interpretation of the results in the practical context of hospital management.
