Ranking of Iranian provinces based on healthcare infrastructures: before and after implementation of Health Transformation Plan.

BACKGROUND: Health Transformation Plan (HTP) was occurred in 2014 to improve access and equity and reduce out of pocket payments in Iranian Health Care System. In this regard the aim of this study is evaluating and ranking the service provider's infrastructures among the country provinces as an indicator of equity before and after implementation of the HTP.
METHODS: This cross sectional study is conducted in 2017. The study population included 31 provinces of the country. Data related to 4 years from 2012 to 2016 were included from the data bases of Ministry of Health and Medical Education as well as the statistics yearbook of the country. The obtained results of multi-criteria decision-making methods were analyzed as well. SPSS18 and Excel2013 software were used for data analysis.
RESULTS: Based on the VIKOR method, in 2012, Mazandaran, Tehran and Fars provinces and in 2013, the provinces of Tehran, Fars and Isfahan ranked from first to third respectively. Similarly after HTP, in 2015, the provinces of Tehran, Khorasan Razavi and Fars and in 2016 the provinces of Tehran, Fars and Khorasan Razavi have ranked from first to third respectively. Paramedic, dentist, pharmacist, medical institutions and hospital bed had a significant difference before and after the implementation of Health Transformation Plan, so that the number of these indicators increased after implementation of the HTP (P value < 0.05).
CONCLUSIONS: According to the results, there are many differences between the provinces and these disparities have not decreased significantly after HTP. Consequently, it is suggested to the health sector policy makers to make regional plans and allocate the budget of HTP, based on the status of the provinces. In addition, responding to these inequalities requires a transparent and systematic approach to provide the budget for allocating to the population, health needs, and the lack of development and geographical isolation of regions.

Background

Fair distribution of financial resources in the health care system helps to reduced health inequalities and health outcomes [1, 2]. Moreover, the right of people to access health services and fair health care has been considered as a major issue by many national and international organizations [3]. Besides, the World Health Organization considers the improvement in health equity both in international and national, as one of the greatest challenges of the new century [4]. On the other hand, various factors of health systems affect the health promotion and reduction of health inequalities, including leadership and stewardship, strategies and policies, health system structure, inter-sectors cooperation, health sector reforms and the mechanisms of allocating health care resources [5]. In this regard, resource allocation as well as healthcare Infrastructures is considered as one of the most important tools for promoting equity in health [6].

Against the emphasis on fair allocation of the resources, the results of various studies indicate the unequal distribution of rural health houses in the provinces of Iran [7], unequal distribution of primary care physicians in different regions of Greece and Albania [8], and unequal distribution of physicians in rural areas of the United States in 2005 [9]. Australia is also the third largest country in terms of regional disputes [10] and increasing the inequality regional disparities is as a serious concern in Russia [11]. While health systems are looking for better ways to meet current and future challenges, and developing countries, including Iran, aren’t exception in this respect.

The budget allocated to health in Iran by 2014 has been less than 8% of the total state budget [12]. In recent years, Iran’s health system has suffered from problems such as the high direct out of pocket payments (OOP) and the increase in households’ catastrophic costs [13]. So that OOP increased from 40.63 to 54.64 percent between 2008 and 2014 [13] as well as the percentage of households faced with catastrophic costs varied from 8.3 to 22.2% by 2012 in different regions of the country [14]. At the same time, the outbreak of chronic diseases in Iran and the accumulation of health centers in large cities have resulted in poor accessibility or even lack of access to services in other deprived areas [15].

Over the past three decades, the Iranian government has made significant efforts to promote health and reduce health inequities through the establishment of a primary health care network (PHC), the implementation of the rural family physician program, rural health insurance program and national health insurance, but there is still a concern about the fair access to health cares [16]. These deficiencies led the policy makers to adopt a reform known as the Health Transformation Plan (HTP). The program follows several goals in a step-by-step process to achieve universal health coverage. One of the most important goals of this program was to reduce the Out of Pocket (OOP), which is considered as the most inefficient and descending financing mechanism [14].

Another important goal of this plan is to prevent referral of patients to centers outside the hospitals affiliated with the Ministry of Health for the purchase of medicines, laboratory and radiological equipment and services, strengthening special clinics and promotion of outpatient care services, supporting the retention of physicians in deprived areas, increasing the presence of specialized physicians residing in hospitals affiliated to the Ministry of Health and improving the hotel accommodation quality in governmental hospitals [17]. Given that the difference in health care services in the various areas of Iran is high and most of the specialized physicians, hospitals, laboratories, medical rehabilitation centers are in the big cities and provincial centers [18], so in this plan, the state has tried to provide the deprived with access to health services and focus on improving the quality of health services provided in deprived areas, and hopes that the implementation of this plan will lead to fair access to health services [19].

The first phase of this HTP, focusing on health services and governmental hospitals affiliated with the Health Ministry, was launched in May 2014; and continued with the modification and updating of medical tariffs on October 2014 [20].

Given that health system, like any other system, is a set of interrelated parts that should work together for effective function. Health infrastructure is one of the components of effective health services provision. Health infrastructure includes buildings, facilities, equipment, personnel and technology, and WHO also considers the effectiveness of infrastructure distribution as an important challenge [5]. There were significant resources in the Health Transformation Plan in Iran, and personnel and facilities increased in the country, but only the number of health care resources is not effective on people’s health, but also the distribution of resources is important. And the unequal distribution of health services is a major obstacle to improve health services provision in world health systems [7].

Regarding what was discussed, it seems that unbalanced distribution of healthcare resources is associated with different providing opportunities and capabilities for the provinces of the country. Considering the most important goal of the Health Transformation Plan means reducing health inequalities in the country, the matter will be more important. Meanwhile, one of the necessary information bases for proper national and regional planning is awareness of the capabilities of different provinces. Therefore, determining the position and status of different provinces in terms of development level before and after implementation of the HTP is very important. In addition, this study was conducted with the aim of evaluating and ranking the provinces of the country based on the healthcare infrastructures before and after implementation of the Health Transformation Plan.

Methods

This is a cross sectional descriptive-analytic study, conducted in 2017. The study area included 31 provinces of the country (Fig. 1). In this study, the data related to 4 years of the provinces of the country (2012 and 2013 before the development of the HTP), 2015 and 2016 (after the development of the Health Transformation Plan) were studied; and the required statistics and information from the data bases of Ministry of Health and Medical Education as well as statistics yearbook of the country were prepared. Considering that 2014 is the year of implementation of the plan, so the data of 2014 have not been included in the study analysis. On the other hand, based on the four studied years (2 years before implementing HTP and 2 years after that), in addition to perform the ranking, it was possible to examine the process of changes for each indicator in each province. In this regard, multi-criteria decision-making method was applied. This method is one of the decision-making methods in which the problem has multiple criteria and the purpose of the decision is based on these multiple criteria [21]. SPSS18 and Excel2013 software were used to analyze the data.

A map of Iranian provinces [21]

In the ranking of the provinces of the country, 11 effective indicators in the field of health and treatment (including paramedics, staffs, general practitioner, dentist, pharmacist, specialists, medical institutions, hospital beds, diagnostic laboratories, rehabilitation centers and pharmacies affiliated with the Ministry of Health, and Medical Education) whose data are available, were used. The selection of such indicators has been based on the objectives of the Health Transformation Plan and having access to available data. In addition, Shannon’s entropy method was used to calculate weights of each of the examined indicators in this study.

The “entropy” is a very important concept in the social sciences, physics and information theory, and when the data of a decision matrix is fully characterized, this method can be used to evaluate weights [22]. In this way, if is the number of options and is the number of indicators, the weight of the indicators is obtained briefly by taking the following steps [23]:

Step 1: Calculating the probability distribution through the following relationship:

Step 2: Calculating the amount of entropy in which

Step 3: The amount of uncertainty is obtained.

Step 4: Calculating the weights of the indicators will be calculated by the following equation.

The VIKOR method was used to rank the provinces of the country. The VIKOR method is one of the multi-criteria decision-making methods introduced by Opriukovich and Tsugon in 1998.

This method evaluates issues with inappropriate and incompatible criteria. It has been developed to multi criteria optimization of the developed complex systems; and is as a determiner of a list of compromise ratings, compromise and intervals solutions for fixing the weight of the criteria. This method focuses on ranking and selection of alternatives despite existing conflicting criteria.

VIKOR introduces a multi-criteria ranking index based on a specific criteria of proximity to the ideal solution. In this method, it is assumed that each alternative is evaluated according to the criteria function, and compromise ranking can be made by comparing the criteria of proximity with the ideal alternative.

An aggregate LP metric function is used for a compromise rating [24].

Suppose that the alternative is specified with . For alternative, the degree and the amount of degree of is determined by . That is, is the value of the criterion function of for the alternative, in a way that, is the number of criteria. The development of the VIKOR’s method begins with the following form called the LP metric:

Based on the VIKOR method, the value of (as in equation (1) and [as in equation (2) is used to formulate the ranking criterion.

The obtained result from expresses the maximizing group desirability (the rule of the majority) and the obtained results of , expresses minimizing the regret of individuals from the opponent alternatives.

An agreement solution of is a justifiable answer to an ideal solution of , and compromise means an agreement reached through bilateral negotiations as depicted in Fig. 2:

Fig. 2

Ideal and compromise solutions

The VIKOR’s compromise ranking algorithm includes the following steps: [24]

Step 1: Determining the best and worst value of for all criteria functions if th function represents an advantage (positive aspect) in this case and .

Step 2: Calculating the values and for using the following relationships:

In a way that expresses the relative weight of each criteria and indicates the relative importance of each one.

Step 3: Calculating the amount of for using the following equation:

In a way that:

In this regard, the weight of the strategy is introduced “the majority of the criteria” (or the maximum utility of the group), which is here .

Step 4: Ranking alternatives by sorting descending values of . So the results of the three lists are ranked.

Step 5: It is suggested that a compromise solution to be considered for the alternative ranking by the minimum criteria of if two conditions are met.

Condition 1. Acceptable advantage: it should be . In a way that is an option having the second position in the classified list of and so that is the number of alternatives.

Condition 2. Acceptable stability in decision making: Alternatives should have the best rank in the list . That is, this reconciliation must be stable in a decision making process. So that under any circumstances (majority voting , agreement with , veto with ) to be set.

If one of the conditions is not met, a set of compromise solutions is suggested:

Options and if the only second condition is not meet.

Options , if the first condition does not occur and is determined from the following equation: M for maximum.

The best alternative ranked by the index is the amount with the minimum quality. The method of VIKOR is a useful tool in multi-criteria decision making, especially when the decision maker is not able to express its preferences at the beginning of the system design. In order to compare the data before and after the Health Transformation Plan, after examining the normality of the data, the paired t-test was used.

Results

In order to prioritize the alternatives, it is necessary to extract the weight of the criteria at first. As previously mentioned, using the Shannon entropy method and applying the formulas to, the weight of the criteria was extracted each year, and the final weight was obtained based on the average in Table 1 (1, 4). Since the number of alternatives for prioritizing is equal to 31, in formula, we put m = 31 for computation k in order to calculate the value of entropy (2). Therefore, the k value is 0.291, which remains constant during the calculation. According to the entropy method, given the specific criteria, the greater deviations result in greater weight. Table 1 shows the results of Shannon’s entropy. According to the table, the number of pharmacies and with small difference, the number of rehabilitation centers indexes had the maximum weight; and the index of paramedic number had the lowest weight among the understudy indicators.

Table 1

Weight of the indexes studied by entropy method

Pharmacy	Rehabilitation centers	Diagnostic lab	Hospital bed	Medical institution	Specialist	Pharmacist	Dentist	General medicine	Staffs	Paramedic	Indicators
0.145	0.143	0.066	0.083	0.049	0.108	0.111	0.079	0.067	0.08	0.063	Weights

Having calculated the weight, the decision matrix must be normalized to determine the priority of the alternatives. According to Opricovic and Tzeng, in order to implement VIKOR the use of linear normalization provide satisfactory solutions [24, 25]. This is mainly because of not depending values to evaluation unit of a criterion function. Then, it is necessary to determine best and worst value of all criteria. The best value is the ideal solution so that for the criteria that are inherently positive, the larger the number we are closer to the ideal. On the other hand, if the criterion is intrinsically negative, the lower is the ideal state. The negative ideal solution is in contrast to this. In other words, a negative ideal means having high values for intrinsically negative and small amounts for intrinsically positive indicators. Accordingly, for each decision matrix in each year, positive and negative ideal values were calculated, and the values of S, R, and Q were obtained using formulas (7) to (9). Furthermore, the value of v was considered to be 0.5 () implying the weight of the strategy of ‘the majority of criteria’’ in VIKOR method. The values of Q and R for each of the alternatives (provinces) were reported based on the data of 2012 and 2013 that were before implementing the Health Transformation Plan; and 2015 and 2016 that are after implementing the mentioned plan: If the values of Q and R are set in descending form, two ranked tables will be obtained.

As it is shown in Table 2, based on the VIKOR method, in 2012, Mazandaran, Tehran and Fars provinces ranked from first to third. Since the condition (1) Acceptable advantage is done in the VIKOR method, the acceptance benefit condition is confirmed.

In addition, based on the VIKOR method, in 2013, the provinces of Tehran, Fars and Isfahan ranked from first to third respectively. Since the condition (1) Acceptable advantage is done in the VIKOR method, the acceptable benefit condition is confirmed.

As shown in Table 2, since the R ranking is similar to Q, then for the years 2012 and 2013, the second condition, that is, the acceptance of the decision making, will be met.

On the other hand, according to the VIKOR method, in 2015, the provinces of Tehran, Khorasan Razavi and Fars gained the rank of first to third respectively. Since the condition (1) Acceptable advantage is done in the VIKOR method, the acceptable advantage condition is approved.

Based on the VIKOR method, in 2016 the provinces of Tehran, Fars and Khorasan Razavi have ranked from first to third respectively. Since the condition (1) Acceptable advantage is done in the VIKOR method, the acceptable advantage condition is confirmed.

As shown in Table 3, since the R ranking is similar to Q, then for the years 2015 and 2016, the second condition, that is, the acceptance of the decision making, will be met.

As the figure shows this country has 31 provinces that all are administrated by the central government.

According to the results of Table 4, paramedic, dentist, pharmacist, medical institutions and hospital bed had a significant difference before and after the implementation of Health Transformation Plan, so that the number of these indicators increased after implementation of the HTP (P-value < 0.05).

Discussion

Studies in the field of inequality indicate the importance of reallocation of resources in health policies and decisions make on health field, and developing countries including Iran, through general coverage of insurance, rural insurance, and family physicians have been trying to reduce these inequalities [26]. On the other hand, unequal distribution of health services is a major barrier to provision of improving health and treatment in the health systems across the world, and there is a link between access to health care resources and health status [27]. Therefore, understanding the mode of distribution of health facilities among the provinces of the country and analyzing them to identify the deficiencies and provincial failures is considered as the first step in the health and treatment planning. Organizing shortcomings through logical and prioritized planning for the provinces is considered as a second step.

The findings of this study indicate that in 2012 and 2013, as the years before implementation of the Health Transformation Plan, the provinces of Mazandaran, Tehran and Fars in 2012 and Tehran, Fars, Isfahan in 2013 in terms of investigating the developing indicators have been in a better position respectively. These results are probable and inevitable because Tehran is the political capital of the country and most of the health facilities are concentrated in this city. Isfahan, Fars and Mazandaran as three other metropolitans of the country had the same situation. In another words, most of the educated workforce in medical and para medical scopes have tendency to work in these cities with higher living facilities and higher incomes as well. In this regard Health Transformation Plan tries to move toward equality by reallocate the health infrastructures all over the county But as the present results indicated, the status of these indicators in 2015 and 2016 implies that the provinces of Tehran, Khorasan Razavi and Fars in 2015, Tehran, Fars and Khorasan Razavi, are respectively in better position than other provinces of the country. As we emphasized before, it should be noted that these provinces are as the megacities of the country; and the main focus of health and treatment facilities is on these provinces. Therefore, these results are not far-reaching and, given the level of existing facilities in these provinces, the results are logical although they lead to the reality that implementing of HTP can not differ the status of the poor regions from the perspective of health facilities.

The results of Kazemi et al. [28] and Bahrami et al. [18] confirmed the results of this study and reported these provinces as developed and enjoyed ones. On the other hand, in 2012 and 2013, respectively, the provinces of Kohkiluyeh and Boyerahmad, South Khorasan, North Khorasan in 2012 and Eilam, Kohkiluyeh and Boyer Ahmad and Ardebil in 2013 were in the worst situation in terms of enjoying the under study indicators. The stated provinces are all under developed and territory regions with lower level of incomes and social determinant of health status along with less physical facilities and lower tendencies of educated work force for staying there.

As other results show, In 2015 and 2016, as the years after implementation of the Transformation Plan, respectively, the provinces of Kohkiluyeh and Boyerahmad, Ardebil, North Khorasan in 2015, and Kohkiluyeh and Boyerahmad, North Khorasan and Kurdistan, are in the lowest status of enjoying the considered indicators. These provinces are as the deprived and less developed regions of the country; they have remained relatively less enjoyed after the implementation of the Transformation Plan. It well indicates that HTP helps the developed provinces become flourished and more developed and in contrast, the under developed provinces remained deprived and needful.

By investigating 10 provinces with the lowest Q values (best situation) and comparing them in the years before and after the Transformation Plan, the slight changes are seen in these rankings, and most provinces are almost constant at these 10 rankings. On the other hand, investigating the situation of 10 provinces with the highest Q values and in the worst conditions in terms of the understudy indicators that are mostly as deprived and poor provinces, show the similar results with the previous obtained results; and almost ranking the provinces is fixed and without change.

In recent years, little research has been carried out on the performance of the provinces in the infrastructures of health and treatment area in macro scale; and most of the studies have been conducted on the ranking the counties of province regarding enjoy the health facilities level.

Amini et al. [29] ranked the provinces of the country in terms of health; and the results showed that the provinces of Isfahan, Tehran and Markazi were in good health situation. They report that the situation of Khouzestan, Sistan and Baluchestan and Kohkiluyeh and Boyer Ahmad provinces are critical [29].

In the same study in Serbia, there are also severe regional inequalities between the north and the south, urban and rural areas, as well as the central and peripheral regions. In this country, the province of Vojvodina and the city of Belgrade show a greater development than other regions of Serbia, especially in the southeastern regions. These inequalities become more and more day by day [30].

The results of this study indicate that the Health Transformation Plan has not been so successful in reaching its goals. Its goal was the equality in access to health services and justice in distribution of these services. Now, the provinces that were in good condition before the implementation of the plan and are at the central region of the country, after the implementation of the Health Transformation Plan has found a better situation. They are still in a better position. Besides, the provinces that had the least access to health services before the implementation of the Health Transformation Plan, and were generally peripheral and poor provinces, are still in the worst conditions after implementation of the plan.

It seems that there are many differences in terms of distribution of health indicators in the provinces of the country; and the provinces in the border are at the lowest level of enjoying. Furthermore, despite the implementation of the Health Transformation Plan, no significant changes in the status of the provinces were observed in comparison with the before implementing this plan. Based on the findings of a study conducted by Himanshu et al. the first 6 years of the National Rural Health Mission in India has increased the coverage of mothers’ health care and has reduced regional inequality unevenly [31]. The results of the study done by Dai et al. also showed that regional inequalities in financing the new cooperative medical scheme in Jiangsu weakens the equality of using healthcare between the regions; therefore it is necessary that a fairer financing to be existed to reduce regional inequalities [32]. However, Shikeri et al. conducted a study on measuring the health indicators in different regions of Tunisia, and the obtained results show a decreasing trend in regional disparities in recent years, which is inconsistent with the results of the present study [33].

Conclusions

According to the results of this research, there are many differences between the provinces of the country and these disparities have not decreased significantly after the implementation of the Transformation Plan. Consequently, it is suggested to the planners and officials of the health and treatment sector to make regional plans and allocate the budget of Health Transformation plan, based on the status of the provinces. In addition, responding to these inequalities requires a transparent and systematic approach to providing the budget for allocating to the population, health needs, and the lack of development and geographical isolation of regions.
