The overall smartness status of the hospitals was moderate. None of the seven hospitals exhibited an excellent smartness status. Two hospitals had a moderate status, and one had a good status. However, none of the non-teaching hospitals showed good status, with three having a moderate status and one having a weak status. Despite the progress of hospitals in developed countries towards smartification and their favorable status in this technology, a complete understanding of the value of investments in smart technologies has not yet been achieved (
16), and this approach is still in its early stages. It is expected that with the rapid growth of this technology and the increasing needs of the studied hospitals, the observed statuses in the findings will improve over time.
Among the examined smartness statuses, no excellent or poor statuses were observed. The domains of clinical processes, management systems, and green management were in a good status, while hospital building, hospital units, safety processes, patient processes, and information technology were in a moderate status. In line with Rasoulian Kasrineh et al. (
34), effective and efficient resource management has been emphasized across various domains in this study. Additionally, a study using similar smartness metrics indicated that the Mayo Clinic and Johns Hopkins Hospital ranked at the top level of smartness (
35).
In the smartness of hospital buildings, no excellent status was observed. The overall status of teaching hospitals was better than that of non-teaching hospitals. In infrastructure development, smartification can lead to long-term cost savings and reductions in maintenance costs, making investment in smartification economically justifiable (
11). The design of hospital buildings, as the main framework for implementing smart hospitals, should be compatible with appropriate smart technologies and equipment (
36) and aligned with the infrastructure and functions of urban communities (
37).
The smartness of hospital units, which include various clinical, paraclinical, administrative, and support departments, was moderate. On average, teaching and specialized hospitals had better smartness statuses than general non-teaching hospitals. Considering the significant statistical relationship between hospital units, type of hospital (teaching or non-teaching), and specialization (specialized or general), it is evident that the addition of educational responsibilities and the presence of professors, mentors, and students in various units, along with the need for innovative educational interventions (
38), resulted in better smartness statuses in teaching hospitals. Additionally, specialized hospitals often deploy more specific equipment and demonstrate more precise performance in their areas of specialty (
39), which increases their potential for smartification.
A significant and direct statistical relationship was also observed between the smartness of hospital units and information technology smartness. Since one of the primary pillars of hospital smartification is related to information technology, the development of IT in hospitals extends to various hospital units, ultimately increasing the level of smartness in those units (
40). Conversely, as the smartification of units progresses, their equipment and technologies also become smarter.
Patient safety is a vital and sensitive aspect of hospital smartification. The use of artificial intelligence in hospitals can enhance patient safety (
41). The study findings indicate that the smartness status of teaching hospitals is better than that of non-teaching hospitals. Kakemam et al. (
42) also revealed that attention to patient safety in Iranian teaching hospitals is good. Additionally, a significant difference was found in the average scores of safety processes among the seven hospitals. The smartness of patient safety processes may differ among hospitals due to various leadership styles and management perspectives (
43). Smartness in patient safety requires a unified, integrated approach and should be free from personal biases to ensure compliance with different characteristics and management approaches (
44).
The smartness status of clinical processes was good overall. Two non-teaching hospitals achieved excellent status, two teaching hospitals were rated as good, and the remaining centers had moderate statuses. The findings showed a significant and direct relationship between the smartness of clinical processes and the overall smartness status of the hospitals. Therefore, the smartness of clinical processes, as the primary and most sensitive provider of hospital services (
45), plays a key role in the overall smartness of the institution. Additionally, a significant relationship was observed between the smartness of clinical processes and management systems. Since smart management positively impacts organizational performance (
46), it is expected that as the smartness of management systems improves, so too will the smartness of clinical processes in hospitals.
Smartification can increase efficiency and reduce the time spent on managerial support services (
47). According to the findings, the highest level of smartness was observed in management systems, with four hospitals being rated as excellent. One reason for this is the availability of monitoring tools and the overall development of information technology, along with indirect supervision by the Ministry of Health and Medical Education (MoHME) and centralized oversight by the University of Medical Sciences on hospitals and managers' performance (
48). A smartification approach and the commitment of hospital management are crucial for increasing smartness. Hospital managers should strive to equip their organizations with smart hospital components and align all processes and equipment with transformative technologies (
14). Continuous monitoring by managers is also necessary to ensure goal achievement at all levels (
49).
The smartness status of patient processes was moderate, and most hospitals (five cases) were in a weak status. It appears that patient process smartness has not received sufficient attention in hospitals. Ryu et al. emphasize the importance of patient-centered smart services (
50). Patients are value-creating customers for the hospital organization, and efforts to make processes related to them smarter will positively impact their satisfaction (
51) and ultimately contribute to the hospital's success in achieving its organizational goals (
52).
The smartness of green management in hospitals was rated as good or moderate, with the average status being moderate. Smart performance in this domain can promote environmental sustainability and contribute to the hospital's sustainable development (
53). Optimal energy management is also emphasized, as it can lead to cost reductions for the hospital (
54). The findings revealed a significant difference in the average scores of smartness in green management among the seven hospitals, reflecting different approaches and performances. This indicates a lack of a unified, centralized approach to green management.
Hospitals’ smartification is achievable through innovative information technologies, and success in utilizing and implementing IT can positively impact the smartness of other sectors (
1). However, the overall status of hospitals in this domain was moderate or weak, which is not desirable. Smart hospitals can optimize care and reduce costs through digital communication technologies such as video conferencing, SMS, remote monitoring, and telehealth. The Internet of Things is also a critical component of the IT domain, and its use in various healthcare stages can reduce errors. However, considering its effectiveness varies across diseases (
2), its use should be approached with caution.
Given the importance of smartification and the growing need for technology, we recommend that hospitals develop short-term, medium-term, and long-term plans for smartification. Since there is no national obligation, hospitals should voluntarily take steps towards smartification. Additionally, we suggest that the smartness status of hospitals be included as a separate category in national accreditation evaluations conducted by the MoHME. Including smartness status evaluations in internal evaluations conducted by Medical Universities' Deputies could also be beneficial. Public incentives and active industry participation are necessary to strengthen and facilitate the smartification of hospitals (
7).
We recommend that medical universities and hospitals implement smart systems in their management departments to kick-start smartification. This can help managers understand the importance and utility of smartification and act as a driving force for overall hospital smartification. Considering the significant differences in performance among hospitals in safety and green management, we suggest that a comprehensive action plan and monitoring program be developed by the MoHME and Medical Universities. This plan should incorporate the experiences of successful universities and hospitals and aim for the integrated implementation of smartness metrics in these domains.
5.1. Limitations
Given the novelty of the smart hospital concept and the limited number of relevant studies, achieving a comprehensive comparison among the relevant domains was not possible, which is one of the limitations of this study. Additionally, the lack of familiarity of hospital managers and staff with the study and some of the metrics necessitated separate explanations for them.
5.2. Conclusions
Considering that the smartification of hospitals, especially in developing countries like Iran, is in its early stages, it is not surprising to observe unsatisfactory conditions in overall status and related domains, particularly in public hospitals that face numerous challenges. The observed statistically significant correlation between two hospital characteristics and one of the smartness domains supports the hypothesis that a hospital's general attributes are associated with its level of technological sophistication. This finding warrants further investigation to elucidate the relationship between hospital characteristics and various dimensions of smartness. Additionally, the lack of correlation between performance indicators and smartness status can form the basis for further research. The interplay between the overall smartness score and other factors highlights the need for attention to all dimensions of smartification and a cohesive approach to its implementation. Given the challenges faced by public hospitals, smartification is likely to assist in mitigating these issues, and therefore, it is advisable to prioritize smartification and expedite the implementation of all its domains in hospital agendas.
