Introduction
Health is one of the most important human concerns and the health system with its new definitions, has an increasing role in maintaining and improving health in the community. The high cost of health services is a kind of health expenditure that exceeds a certain level of household income (often 40%) (1). For many years, national and international health authorities in different countries have been seeking ways to provide appropriate mechanisms to finance these services in support of people, especially the poor, and have proposed different methods (2). The country's basic types of insurance include social insurance, health insurance, the armed forces medical insurance, sand Imam Khomeini Relief Committee insurance under the auspices of Welfare and Social Security Ministry, each of which includes different individuals and groups in the community, and the government has also a different contribution to finance each one of them (3).The insurer organizations and hospitals interact under a binding contract. On the basis of the right to terminate, if one party breaks one of the provisions in the contract, the other party can terminate the contract and avoid further losses (4). One of the important factors in the financial affairs of the hospitals is the problem that arises from the lack of financial and accounting management in hospitals which imposes costs on hospitals.
Despite the shortage of hospital funding, what makes matters worse is the reimbursement of the insurer, which is usually delayed and deducted. Because the insurance company is committed to paying part of the health costs of the insured in the hospital. The widespread health insurance coverage leads to an increase in demand for health services. As a result, existence of insurance can lead to inflation in healthcare services price (5). The source of the hospital's income concerning the implementation of the public insurance law and sale of services to the insured people under insurance coverage is provision. Usually, each month, the insurance company deducts amounts under the name deductibles from the total of the requested amounts after examining the financial records of the hospitals (6). The main source of hospital's funding is insurance, but hospitals in some cases have issues with the insurer, and typically all of their debts are not collected. The magnitude and the cause of deductibles are important in such a way that they raises the awareness of the hospital's staff and management, and also increase hospital's income and create mutual trust between the two parties (7). Lack of technical knowledge and communication with foreign insurance companies, poor awareness of insurance, risk aversion of government officials, weaknesses in insurance laws and regulations, lack of insurance justice, lack of interaction between the insurance industry and the Islamic Consultative Assembly, mismatch of insurance products with the demand of society, the insignificant presence of insurance companies in the global market, disregard of training highly qualified and efficient workforce, and the limited research activities are among the challenges of the insurance industry in Iran (8). According to the latest valid statistics from Central Insurance of Iran, the penetration rate of insurance in Iran was 1.734% in 2013 , which compared to the previous year it has decreased by 6.22%. The damage factor in 2011 was 76.6%, which increased up to 90% in 2013 (9). Compared with the global statistics average, these statistics show the lack of development in the insurance industry and the existence of major challenges. The existence of fundamental problems in the country's insurance system has formed a tight and unprecedented cooperation between the basic and to some degree the insurance extension organizations and the health authorities of the country, but it is fragile and temporary (10). With the current situation, despite the efforts and services of the managers and the caring personnel of the insurance system in the country, the system will fail to achieve the goals of public health coverage in order to reduce patients' costs, resulting in a lack of budget and heavy debt while meeting these needs (11). The existence of an optimal insurance system is an important factor in improving health, economic growth, welfare and community development (12). To explore the existing behavioral challenges and understanding the interdependencies of parties within the health system, game theory can be used. Game theory is the science of studying strategies and the interaction between rational decision-makers. One of the main applications of game theory is to investigate interactions between organizations (15) Therefore, in order to solve this problem, this study decided to investigate the interaction of insurer systems with the health system, identify factors affecting this interaction and design an insurance mechanism to cover the gaps of insurance systems and the health system based on game theory.
Methods
This study consisted of two phases of qualitative and quantitative. In the qualitative phase of the study, a goal-based sampling method with maximum variability was used to select the participants. The analysis of interview data was considered as a guide for subsequent interviews. Therefore, sampling continued until data saturation. Two groups of participants took part in the study. The first group consisted of 20 experienced experts from the health system in the field of insurance, and the second group included 13 authorities and experts in insurance organizations in Yazd. The main method of data collection in the qualitative phase was a semi-structured interview and through phone contact with the participants, interview time and appropriate location were determined. Interviews were recorded anonymously assuring the confidentiality of the information. If the participants were not willing to answer a question, they had the right not to do so. They were informed that, if necessary, they may be referred to again for complementary talks. Participants could have the results if they wanted to.
Individual interviews with participants of the widest variety in terms of work background and diverse work experiences were conducted. Given the circumstances and the participants' willingness, the interview time was between 30 to 60 minutes. Interviews were recorded by a recorder, and
then immediately written down word-for-word, so the data was prepared. Data analysis began simultaneously with data collection, and the text of each interview was studied several times. Then the words and sentences related to the participants' conversations, which contained important points about factors affecting the interaction between the insurance organizations and the health system were selected as semantic units, after that, the semantic units were labeled as the summery of a semantic unit whose text was encoded. By reviewing, comparing the codes with each other and integrating the same codes, the codes, as well as the text, were reviewed. The classifications and their extension continued based on similarity and proportionality. To ensure codes' strength, class review and recomparison of the data was conducted. For analyzing and encoding text, MAXQDA10 software was used.
In the quantitative phase of the study, a questionnaire was designed based on the data collected in the previous phase. First, some games were designed based on extracted interactive behaviors After the qualitative one; a questionnaire on games was distributed among participants in insurance organizations and health system in Yazd. Due to the limited population of people involved in insurance organizations and health system, efforts were made to include them all. The data collection tool in the quantitative phase was a questionnaire containing 140 questions. It represented 35 games from among the interactive behaviors between the health system and insurance organizations. Each behavior was presented as a question in the questionnaire, each question having two answers (agree and disagree).
With regard to the population of insurance managers and experts who carry out insurance affairs in Yazd, and also with regard to the population of authorities and experts at different levels of the organization and concerning the insurance issues in Yazd University of Medical Sciences, they were all considered as samples. The number of participants in this study was 42 from the health system and 40 from insurance organizations. In order to verify the validity of the questionnaire, after the thorough review by the research team, the finalized questionnaire was sent to 10 experts to confirm the content validity and to receive complementary comments. In order to examine the face validity and proportionality of content with the characteristics of the sample, a pilot study was conducted with 20 experts and authorities of insurance organizations and the health system in Yazd. Cronbach's alpha coefficient was 0.78 in the present study, which indicates the high reliability of the designed tool. After collecting data by questionnaire, the obtained data was analyzed using SPSS24 software and the frequency percentage of responding to each question, which included agree and disagree answers, was obtained separately for each group. After that, using GAMBIT software, the Nash Equilibrium was determined in each game, which represented the optimal behavioral strategies between the insurance organizations and the health system that occurs when each player considers the decisions made by another player.  Also, the optimal behavioral strategies containing best outcomes were introduced. Then a health insurance mechanism based on game theory was designed.
Results
In the qualitative phase of the study, after interviewing two groups of insurance experts in insurance organizations (20 people) and health system (13 people), 620 codes were extracted. The codes were classified into 3 main categories and 11 sub-categories according to Table 1.

In the quantitative phase of this study, 35 games and behavioral strategies in accordance with codes were designed. All of the experts working in both the insurance organizations and the health system who were involved in insurance affairs were studied. The sample included 82 people among whom 36 (43.9%) were men and 46 (56.1%) were women. 48.8% of the participants were from insurance organizations, and 51.2% were from health system experts. The undergraduate with 59.8% had the highest frequency. The average age of the experts was 36.98 years old, and the average work experience was 12.85 years.
After entering the questionnaire data into the SPSS24 software, the frequency percentage of the response to each game from the two groups of insurance organizations and the health system was inserted into GAMBIT software, and the marginal benefit of the optimal interactive behavioral strategies (Nash equilibrium) for two insurance organizations and health system were extracted.

Discussion
This research showed a framework of interactive behavioral strategies between the health system and insurance organizations. In Table 1, 35 games were designed and presented in 3 main categories and 11 sub-categories. Finally, optimal interactive behavioral strategies (Nash equilibrium) were extracted and introduced for each game separately to insurance organizations and the health system. The subcategories covered a wide range of issues, in such a way that in some cases it was difficult to differentiate them from those presented in other subcategories. In the present study, individual and organizational relationships from both organizations did not seem very satisfactory. As the results of a study showed, the relationship between insurance organizations and health system is built through a binding contract, and the parties do not have the right to terminate, which is one of the most important components of a contract. The right to terminate is one of the most important legal recourses that requires the parties to comply with terms of the contract, and if the contract is breached by one side, the other side can use this tool to avoid further losses, force them to comply with the contract or terminate the contract, with which they are no longer happy due to the other side's breaching (13). The results showed that if hospital personnel were committed to respond to insurance agents and treated them with more respect, files inaccuracies would be reduced. Also, classifying and regular sending of documents will allow insurer agents to handle files faster. It was stated in a research that the use of staff nurses in medical documentation unit to better examine the patient's files can be a solution to the problems of documentation (14). In a study, the results showed that the cooperation of insurance agents with hospital personnel, especially the income personnel, could reduce the workload of the agents, because in the case of problems in files, processing of documents would be delayed (15). In the present study, the results indicated that in cases where insurance agents handle files based on their personal opinions, the hospital personnel would not be willing to correct inaccuracies. In the event of the integration of different types of insurance, it will be easier for hospital staff to respond and decide on insurance affairs. The results of a study similar to this study showed that non-payment of bills by insurance organizations caused the dissatisfaction of hospitals and their distrust of patients and insurers (16). In the present study, it was stated that delay in payments by insurers would make hospitals pay more than the actual price for buying hospital equipment. Hospital deductibles are the main subcategory of the present study. Factors such as carelessness of personnel in entering information, doctors' request of extra pay, 2K doctors, misrecording time or duration of patient's anesthesia, failure to file nursing reports, laboratory reports, imaging reports, and non-attachment of actions and services performed on the patient with no documentation included in the file are the main subcategories of the discussion on deductibles. The results of the study indicated that the agents were also dissatisfied with the doctors' repeat of the request for extra pay for anesthesia and surgery every month because this adds to their workload (17). Due to the fact that the tariffs are not actual, doctors sometimes request extra pay in their reports, and hospital deductibles increase. As in a study, the insurance organizations accused the doctors of abusing the pay system by entering additional codes (18). In another study, the underlying factors of deductible were identified to be the educational and governmental feature of the hospital and problems in treatment and income units (4), which is close to the results of the present study. In this study, one of the reasons for the educational hospitals to face deductibles is students' mistakes. The results of a study showed that due to the educational and governmental nature of the hospitals, there are serious inaccuracies in entering information in files because of hospital's overcrowding, lack of responsible students and interns and training (19, 20). In another study, another reason for deductibles is carelessness of income and accounting staff whose accounts of services are incomplete and do not care to complete files (19). Lack of incentive policies have been identified as another cause of deductibles, which is consistent with the results of the study at the University of Missouri, USA (21). The limitations of this study are the lack of studies related to the interaction between insurance organizations and the health system, as well as the application of the game theory to these issues. Also, non-participation of some key beneficiaries in both qualitative and quantitative phases of both the insurance organizations and the health system can affect the generalization of the results.

Conclusion
The results of this study showed that the health system, and in particular hospitals and, on the other hand, insurance organizations in order to eliminate or reduce problems between them, should try to establish effective communication through the insurance mechanism provided. The main difference between the two organizations, which is the causeof later problems, is deductible. Organizations can help reduce these deductibles by providing correct training as well as integrating systems and reducing disparities between various insurances. Best optimal behavioral strategies in the interaction between insurance organizations and the health system to cover the gaps in the insurance system and improve the interaction between the two organizations in the form of optimal interactive Strategies are provided in Tables 2 to 4 and Figure 1 to provide the insurance mechanism for the two insurance organizations (11 strategies) and the health system (24 strategies) separately.
