Methods: This cross-sectional study involved all the six public hospitals in the province, with 607 registered beds. Data collec­tion accomplished by the use of two ad hoc questionnaires that dealt with both general information and admission data from various hospital wards. The statistical software SPSS-13 used to derive three basic performance indicators, namely aver­age length of stay, bed occupancy rate and bed turnover, which analyzed in Pabon Lasso model. Results: The overall average length of stay, bed occupancy and bed turnover rates were 2.99 days, 62.78% and 76.73 respec­tively. Two hospitals were in Zone III of the model, indicating a satisfactory level of efficiency. Three hospitals demon­strated inefficiency and underutilization of resources by falling into Zone I. one hospital placed in Zone IV. Conclusion: The best approach to address the existing inefficiencies would lie in stopping the expansion of the current facili­ties (e.g. not adding any more beds). As any further expansion will only serve to make hospitals more inefficient. Fu­ture research should focus on why the performance is not at a desirable level and how the situation can be improved.  https://ijph.tums.ac.ir/index.php/ijph/article/view/3197 https://ijph.tums.ac.ir/index.php/ijph/article/download/3197/2996
