Relationship between hospital functional indices and energy consumption

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. 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. 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. 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.
