ABSTRACT
Background: Hospitals use most of the energy and besides, they also can save energy. Since energy costs are of the manageable costs in the hospitals, thus it is possible to wisely interfere in this area. This study is aimed to do a comparative study on energy usage and its management in Farabi Eye Hospital. Materials and methods: This is an applied, cross-sectional and descriptive study which carried out using three-year information of energy usage in studied hospital with consideration to reformative actions in order to reduce energy use through managing it. Data were compared using internal and external benchmarking methods. Results: Since studied hospital was implemented energy use management methods, therefore, results showed a descending trend in water and gas use [according to active bed day and occupied bed rate]. Both water and gas use was reduced to 31% and 28% in 2010 in comparison with 2008 [basic year]. Although, usage rate of electricity [considering bed indices] was also decreased to 10.5% in 2009 in comparison to 2008, it had an increase trend of 5% in 2010 due to applying development and growth strategies. Moreover, if taking "number of patients" index into account, electricity use was reduced to 7% in 2010 compare to 2008. On average, in 3-year period of study, water use was 1.63 times the standard value and electricity was 13.2 and 1.44 times the standard value per active bed day and square meter infrastructure, respectively. Conclusion: Actions related to energy use management played an important role in reducing usage rate in Farabi hospital. Considering hospitals high potentials in lessening energy savings for hospital in the future
ABSTRACT
To investigate the efficacy of limbal-conjunctival autografting technique in patients with primary pterygium. Fifteen eyes of 15 patients with primary pterygium underwent surgery for the removal of pterygium with limbal-conjunctival autograft. After the pterygium excision, the limbal portion of the graft was oriented and sutured to the limbus at the recipient bed with the epithelial surface upside. Recurrence was defined as fibrovascular tissue extension of more than one mm onto the cornea in the area of previously excised pterygium. With a mean follow-up period of 8 months, no recurrences or serious complications were recorded among our patients. Pterygium excision followed by limbal-conjunctival autograft is a safe and very effective way of treating primary pterygium.
