ABSTRACT
Hospital information systems [HIS] are considered prerequisites for the efficient delivery of high quality health care in hospitals. A dialogue is suitable, if it supports the users to realize their tasks effectively and efficiently. Only those parts of the software are presented, which are necessary to fulfill the task. This is a descriptive cross- sectional study. The hospitals which have hospital information systems in Tehran were selected. Then, between these hospitals, depends on companies providing these systems, one hospital was randomly selected. Finally, it was surveyed hospital information systems usability form viewpoint of department secretaries, the nurses and para units users through the standard questionnaire of IsoMetric 9241/10. Data analysis was performed using descriptive tests by SPSS statistical Software. Findings showed that the means of suitability for the task was 3.04 from 5, with respect to users view. Suitability for the task was rated low especially by Para clinic users [2.96] while secretaries [3.03] and nursing staff [3.13] gave the better ratings, but being far from good. It seems that developers of HIS should pay more attention to the following criteria in the software development life cycle: The software should not force user to perform tasks that are not related to his actual work. I am able to adjust the presentation of results to my various work requirements. The important commands required to perform my work are easy to find
ABSTRACT
User satisfaction is a key factor for the success of any information system. Evaluation of hospital information systems HIS is valueless without analyzing users' satisfaction. The purpose of this study was to survey the view point s of nurses, secretaries and paraclinic users about the usability of HIS in selected hospitals. This cross-sectional study was conducted in 2009. A questionnaire, based on the international standard ISO 9241/10, was used to evaluate the usability of HIS. Initially, all hospitals in Tehran with HIS and companies providing the systems were identified. Then, a hospital from among the hospitals, supported by each company, was randomly selected. Finally, the usability of HIS was assessed from the perspective of nurses, department secretaries and paraclinic users through the standard questionnaire of IsoMetric. The collected data were analyzed by SPSS using descriptive statistics and one sample t-test. The findings show that HIS usability was favorable from the perspective of nurses. However, it was perceived less desirable by paraclinic users. The difference in viewpoints suggests that users'job affect the rate of their satisfaction. It is recommended that system providers pay special attention to the needs of paraclinic users, when designing HIS
