ABSTRACT
The present descriptive-comparative study was conducted to give an overview of the messaging standards that are necessary for interoperable electronic health records [EHRs]. We designed a preliminary model after data collection and compared the messaging standards of Health Level Seven [HL7] and the International Organization for Standardization [ISO]. The data were assessed with the Delphi technique. A comprehensive model for the messaging standards of EHRs in the Islamic Republic of Iran was presented in three pivots: structural characteristics [standard for all EHRs, XML-based and object-oriented messages, and dual model]; model specifications [reference model, archetypes and classes of reference model], and general features [distinct ontology, mapping with other standards, and using reference archetypes for exchanging documents]. In conclusion, we gave an overview of messaging standards for the interoperability of EHRs and experts selected ISO13606 as a suitable standard for the Islamic Republic of Iran

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
ABSTRACT
Health information systems have designed in order to manage health information fluency for improving healthcare quality. It is necessary to conduct continues evaluations to do epidemiologic researches and manage health information systems, enhance quality and decrease costs. Unfortunately there isn't framework that focus on the measurement methods and indicators in our country. Objective of this research is defining steps, study design methods, data sources and indicators of health information systems evaluation. This research was cross sectional-description and conducted in 2004. At first studied books in library and searched on the internet to find related information. Then we categorized developed indicators by Canada and England. After that give questionnaire which had 20 key questions with some indicators for each of them to the specialist. Questionnaire given to 35 persons, but it full by 28. these persons were teaching staff in university and specialties in health information systems. Selected indicators as the most important indicators were which over%75 sight selected them high and very high in degree. After gathering questionnaire, results analyzed by SPSS. There are six steps to evaluate health information systems. They include Agree why an evaluation is needed? Agree when to evaluate? Agree what to evaluate, Agree how to evaluate, analyse and report? Assess recommendations and decide on actions. There were 13 study designs for health information systems evaluation. Finally, indicators provided in three contexts accountability, performance enhancement and knowledge development. It is necessary to consider human aspects and knowledge development more over economics and financial aspects. Conducted evaluations of health information system is based on the accountability that conducted with randomized controlled trial and qualitative. The best evaluation is conducted when use some evaluation methods with considering these indicators
