Objective (s): This study aimed to determine the relationship between the hospital functional indices and energy consumption rate in the selected hospitals of Tehran University of Medical Sciences.Methods: The present practical, cross-sectional study was conducted in a period of three years (2008-2010) .The study population included six hospitals affiliated to Tehran University of Medical Sciences. Two categories of information were collected: the information about energy consumption which was extracted from bills and the information related to the bed indicators that obtained from the Information Technology Center of Tehran University of Medical Sciences. Data were analyzed using SPSS software.Results: The results showed that during the three years, the mean water and electricity consumption was 2.99 and 13.38 to 22.3 times above the international standards, respectively. Besides, the average gas consumption was 19.5 cubic meters per bed occupancy. There was a statistically significant relationship between hospital functional indices and energy consumption.Conclusion: Optimization energy consumption and reduction of hospital expenditures can be achieved by culturalization, and learning effective energy consumption management, presenting functional plans, and creating more relationships among the engineering groups and the hospitals.

Aims: Persons with lower-limb amputations need to achieve more natural gait through more effort, leading to an increase in the energy consumption in them compared to the healthy persons. The aim of this study was to investigate the effects of the socket fit on gait energy consumption level in persons with lower limb amputations. Materials & Methods: In the semi-experimental study, 9 persons with below knee amputation, referred to Tehran Veterans Foundation Center, were studied in 2015. The subjects were selected via available sampling method. The study was consisted of two steps, including improper fit and proper fit conditions. The socket fitting was assessed by the trinity amputation scale and the socket comfort scale. The level of energy consumption of the subjects was measured by the physiological cost index. Data was analyzed by SPSS 19 software using paired T test. Findings: Mean values of persons’ gait speed (p=0.001) and the physiological cost index (p=0.019) with improper fit and proper fit were significantly different. Nevertheless, the difference between gait heart beat and resting heart beat at two steps was not significant (p=0.093). Conclusion: Lower energy consumption can be achieved in persons with lower-limb amputations through the utilization of a proper fit, leading to a better gait.
