In this study, 3 main themes of cost reduction strategies included human resources, management and organization, equipment, amenities, and buildings. According to international standards, human resource costs account for about 55% to 60% of total hospital costs (
21). Consistent with Gile and Kendrick's studies, the results of the present study also showed that hospital management could greatly cut down the cost of a health care center by reviewing the human resource structure and recognizing the waste costs of human resources (
22,
23).
In the present study, incentive systems, personnel training and empowerment, recruitment, and layoff systems were identified as some of the human factors that contribute to cost reduction. Our results are consistent with the findings of most studies conducted in the field of encouraging and empowering personnel. Seidemann et al. showed that the system of incentives and motivation in the personnel can affect the effectiveness and efficiency of health care services (
24). Inadequate salary could bring about discontent, absenteeism, complaints, or negligence. Gheibi et al. found that establishing a suitable reward system in Iranian hospitals can result in enhanced customer and employee satisfaction (
25). A study conducted in Turkey was also consistent with our findings. They proved that the formation of hospital committees for staff training could define hospital problems and have a significant role in reducing the cost of conducting tests (
26). However, in 2020, a study did not confirm the results of the current study. The results of the research showed that special attention should be paid to the factors that mediate the learning of the designed training and their application in the desired job. Neglecting these factors over time can lead to their oblivion, and accordingly, a small percentage of them can be transferred to the work environment, resulting in significant costs for hospitals (
27).
The recruitment and layoff system is one of the main tasks of any organization. Other management tasks can be effectively put into practice when there are proper human resources to perform them. Bao et al. used the data envelopment analysis method and found that increasing hospital staff improved hospital performance indicators. This effect was more pronounced with the recruitment of specialists, general practitioners, and nurses respectively (
28). On the other hand, the recruitment and adjustment system, particularly with regard to treatment staff, should be carried out with high sensitivity, which was not mentioned by the interviewees in the present study. According to Chen et al.'s research, in the context of retrenchment, social support through resilience can increase the mental health of medical workers, especially middle-aged ones (
29).
One of the main themes of this study was issues concerning the management and organization of hospitals, in which participants emphasized the hospital information system (HIS) and its impact on hospital financial issues. The results of Almasi et al.'s research mainly showed the positive effects of the HIS on the development of health services (
30). Additionally, a study conducted in 2020 using the opinions of internal managers and information technology specialists of hospitals affiliated with Urmia University of Medical Sciences showed that the design and implementation of the health information management dashboard should be reviewed and revised (
31).
Outsourcing and modification of the consumption pattern are other results of the current research to reduce hospital costs. Management problems in the public sector have led to a reconsideration of how the health system is organized, with a focus on the role of the private sector. In the meantime, some individuals are seeking intermediate solutions to integrate the positive features of both (
32). By outsourcing services and selecting the right personnel to meet the organization's demands, productivity can be increased while reducing costs (
33). The implementation of joint programs between hospitals and the private sector, under the supervision of Iran University of Medical Sciences, can lead to cost management, as demonstrated by the results of this research. There were various results in this field, which are sometimes in conflict and sometimes in line with the present study. In 2023, a study conducted in Iran showed that joint action plans among medical science universities can strengthen performance and competition. However, without proper planning tools, universities may not be able to continue their interventions (
34). On the other hand, in the United States, downsizing, declining human resources, and reengineering are vastly used, and this management strategy results in accessibility of services, quality of care, and cost reductions (
35). Akkermans et al. presented that cost savings and customer satisfaction are the most influential factors in the decision-making process of outsourcing. Also, collaboration with the contractor leads to remarkable improvements in the quality of service (
36). In a systematic literature review conducted between September and November 2021 to identify different concepts of privatization and outsourcing of health care in Iran, the results proved that this process occurred in Iran with a weak monitoring and evaluation mechanism. As a result, it has created an unfair and expensive health care system with low quality in Iran (
37).
Structural changes and the use of new management techniques were other significant points in this study, which were mentioned by the participants as a way to reduce costs. Kaswan and Tucker, in their studies, used new management techniques. Kaswan et al. showed that JIT's concept can be applied in manufacturing companies and boosts effective inventory management and supply chain in service sectors such as health care (
38). Besides, the MBWA approach promotes employees' commitment and working relationships, which are expected to be fulfilled with high confidence (
39).
The preventive maintenance of medical equipment, facilities, and buildings is a way to control hospital income and expenses, which is the third main theme of this study. In terms of selection and purchase of equipment, a systematic methodology should be provided, which is comprised of real needs assessment and equipment purchase management. Jamshidi et al. showed that the use of maintenance management systems for medical equipment saves money, reduces the number of repairs, and raises the maintenance standards in the hospital (
40). According to Shohet's study, a maintenance collection consisting of 7 hybrid key performance indicators (KPI) can be used to analyze and maintain clinical facilities, thereby increasing their lifespan (
41).
5.1. Strengths and Limitations
One of the most important strengths of the current study is collecting the views of managers working in public and private hospitals. Due to the different goals of the hospitals, the strategies used by these managers are different, and collecting them in an integrated format provides a comprehensive view to the experts and officials of the health systems. One of the practical limitations of this study was the difficulty in accessing managers due to their busy schedules. As a result, researchers conducted telephone and internet interviews in some cases to attract their participation in the study. The researchers hope to provide transferability and enable other researchers to conduct studies in this field by being transparent about the limitations of the study, methods of data collection and analysis, selection of participants, and a description of the subject.
5.2. Conclusions
There are several measures that can be mentioned to reduce hospital costs, such as the management of human resources and equipment, the use of centralized information systems as a management dashboard, modification of the consumption pattern, outsourcing, and the use of new management methods. With proper monitoring and management and paying attention to the goals of each hospital, these measures can be an effective step toward improving cost management, evaluating the efficiency of hospitals, and becoming the basis for informed decision-making. By adopting this approach, hospitals can avoid charging high fees to clients to cover expenses and confirm their presence in the hospital. Given that the present study is qualitative and we measured managers’ perception of hospital costs, we suggest that future studies use evidence-based research to identify cost-saving measures that can be implemented in hospitals.
