User acceptance is a precondition for successful implementation of hospital information systems (HISs). Increasing investment in information technology by healthcare organisations internationally has made user acceptance an important issue in technology implementation and management. Despite the increased focus on hospital information systems, there continues to be user resistance. The present study aimed to investigate the factors affecting hospital information systems nurse-user acceptance of HISs, based on the Unified Theory of Acceptance and Use of Technology (UTAUT), in the Shiraz University of Medical Sciences teaching hospitals. A descriptive-analytical research design was employed to study nurses' adoption and use of HISs. Data collection was undertaken using a cross-sectional survey of nurses (n=303). The research model was examined using the LISREL path confirmatory modeling. The results demonstrated that the nurses' behavioural intention (BI) to use hospital information systems was predicted by Performance Expectancy (PE) (β= 2.34, p<0.01), Effort Expectancy (EE) (β= 2.21, p<0.01), Social Influence (SI) (β= 2.63, p<0.01) and Facilitating Conditions (FC) (β= 2.84, p<0.01). The effects of these antecedents of BI explained 72.8% of the variance in nurses' intention to use hospital information systems (R2 = 0.728). Application of the research model suggested that nurses' acceptance of HISs was influenced by performance expectancy, effort expectancy, social influence and facilitating conditions, with performance expectancy having the strongest effect on user intention.

The purpose of this study was to determine the factors affecting the acceptance of Picture Archiving and Communication System (PACS) by healthcare professionals based on the Unified Theory of Acceptance and Use of Technology (UTAUT). A total of 600 nurses, physicians, and paramedical staffs who perform their main tasks using the PACS in educational hospitals of Mazandaran University of Medical Sciences were participated in the study. Construct validity and internal reliability were tested by employing a confirmatory factor analysis (CFA) and a reliability analysis, respectively. Further, structural equation modeling (SEM) was employed to test hypothesized relationships. The results indicated that Performance Expectancy, Effort Expectancy, and Social Influence had a direct effect on Behavioral Intention. Whereas Facilitating Conditions and Behavioral Intention had a direct effect on Use Behavior.

Background The social participation (SP) of the elderly is one of the factors that contribute to the improvement of their well-being. SP, one of the most important factors of active ageing, is mainly influenced by a number of facilitating or inhibiting factors. Aims This study aimed to identify the factors that prevent and facilitate the SP of the elderly population in Iran. Methods A cross-sectional study carried out in Shiraz, southern Iran in 2021. Participants were selected using a convenience sampling method. Shiraz is divided into 11 districts and the largest park in each district is selected for data gathering. The questionnaires were completed by 612 people aged over 60. Data were collected using the Canadian Elderly Survey Project scale and a health-related lifestyle questionnaire and were analyzed using t-test, ANOVA, Pearson’s correlation, and ANCOVA. Results The mean SP score of the elderly in Shiraz was 24.2 out of 60, which is below the midpoint. The results of the covariance analysis revealed that the SP had a significant relationship with the experience of physician consultation, cost barriers, age, marital status, income level, and education level (P < 0.001). Moreover, the results of Pearson correlation revealed a significant correlation between SP and different dimensions of health-oriented activities (< 0.001). Conclusions This study revealed that the main barriers to older people’s participation in health-related activities are cost and access barriers, such as transportation issues. Moreover, higher income level and higher educational attainment have been recognized as the main facilitators of SP in the elderly. In this regard, it can be suggested to apply a combination of health promotion strategies, financial support programs, and development of optimal transportation infrastructure to increase the SP of the elderly.
