Analysis of Developmental Level of Counties of Fars in Terms of Health Infrastructure Indicators Using Standardized Scores Pattern Approach and Factor Analysis

Introduction: It is necessary for planning in order to achieve optimal development, to have knowledge and understanding of the current situation. This identification requires separate areas of study into planning and assessing regions of each area with development indicators and analysis and ranking each area in terms of having gifts of development. The study also aims to analyze the development level of counties of Fars in terms of health infrastructure indicators using standardized scores pattern and factor analysis. Methods: This is a descriptive and applied study, which has discussed the levels of 29 counties of Fars based on 10 health selected indicators using a standardized scoring model. Data were collected using a data collection form developed by the researchers through the Center of Statistics and Shiraz University of Medical Sciences. Results were analyzed using Excel and SPSS 19. Results: Based on calculations according to standardized score and factor analysis methods, Shiraz and Rostam had the most and the least level between the other cities, respectively. Also development coefficient and operating score of the studied counties ranged from a maximum of 0.894 to a minimum of -0.941, and a maximum of 3.861 to a minimum of 2.001, respectively. Discussion: There are relatively large differences between different counties in healthcare sector, and most studied counties in terms of healthcare sector indicators are not satisfactory. So planning how to allocate healthcare resources from policy makers to improve the studied counties is essential.


Introduction
Planning social services, formulating development strategies and success implementing projects, identification and evaluation of capabilities, deficiencies, and determining developmental levels of regions based on a set of appropriate indicators is inevitable. Thereby managers in executive levels are allowed to specify development strategies based on the specific requirements of each region and provide programs coordinated and appropriate to regional conditions (Taghvaei & Avargani, 2007). The planning aims to achieve optimal development and establish balance, which primarily need to understand and identify the status quo. This identification requires separate areas of study into planning and assessing regions of each area with development indicators and analysis and ranking each area in terms of having gifts of development (Zarabi, Mohammadi, & Rakhshaninasab, 2008). Inequities and its dimensions are symptoms of underdevelopment, because actually those countries are known as developed countries that in addition to high social and economic indicators, their income distribution is relatively equitable in its communities, while these values are lower and also its distribution is very unfair (Dadashpour, Alizadeh, & Madani, 2011). In order to assess the level of development, GDP and counties' per capita were first compared and ranked. Assessing development through this method due to taking into account the amount of equity in the distribution of educational services, health care, etc was limited (Mahmoudi, 2011). Several indicators are considered to assess the level of development in a temporal and spatial range, and health is one of these indicators (Amanpoor, Esmaeily, & Jokar, 2012). Among the various development indicators, healthcare index due to its great role in ensuring public health is one of the most important indicators of progress in any country and the success of national development plans to a large extent depends on achieving the goals of this section. Whatever amount and quality of health indicators in a community is more and their distribution is more balanced and appropriate, relative prosperity and more health will exist in that society (Nastaran, 2001). Health and its establishment on basic principles of development are inevitable. Having the required health care needs in Iran has been known as the most fundamental public rights and Article 29 of the Constitution has explicitly emphasized on it. In this regard, the formal sector of health in order to secure and promote the physical, psychological and social health level of the society based on defined policies is a systematic set of activities and executive operations (Mansour, 2004). A glance at the health indicators in the country in the last decade shows on one hand the rapid improvement of the indicators and other on the other hand some inequality in some indicators in different regions and provinces of the country (Movahedi et al., 2009). In any case, it is necessary that Iran like any other developing country pay special attention to the health sector development in order to improve its development position among countries in the world because development in this sector is a prerequisite for the development of other sectors of society. Without a healthy society and people with physical, psychological and social health, it is pointless to address development in other sectors. In order to plan development in health sector of a society, it is first necessary to examine its status in terms of having health indicators (Yang, Zhang, Jia, & Ci, 2005). Today, the issue of development is a concern for many countries. In other words, the development is anything but making a more satisfying life condition for public (Coovadia, Jewkes, Barron, Sanders, & McIntyre). In terms of classifying and developing health in country several studies have been conducted in large scales in counties by mathematical models. Seyedin et al. (2013) in a study entitled "Classification of Kermanshah Province Districts in Terms of Health Structural Indicators Using Scalogram Model" examined the status of the structural health indicators in three groups of institutional, manpower and rural health indicators, and concluded that there is a large gap in terms of having structural health care indicators among different counties of Kermanshah (Mousavi et al., 2013). Amini et al. (2006) in a research using a combination method of factor analysis and taxonomic analysis investigated health ranking of different provinces of country based on having 35 development indicators in health field. The results showed that Isfahan, Tehran, and Markazi were in good health status, but Ardabil, Golestan, and Qom had undesirable health level. In addition, the health status of Khuzestan, Sistan and Baluchistan, and Kohkilooyeh and Boyer Ahmad was in a critical condition (Amini, Yadollahi, & Inanlou, 2006). In other countries some studies have been performed as well, such as Soares et al. (Soares, Marquês, & Monteiro, 2003) in Portugal, Wulan and Petrovic (Wulan & Petrovic, 2012) and Yannis and Andriant (Phillis & Andriantiatsaholiniaina, 2001), which using factor analysis and cluster models and fuzzy logic performed classification of regions with the use of health and economic indicators. Despite all the criticism since 1970s raised on the use of quantitative models in urban issues, if mathematical models are formulated in simple forms and with a limited number of variables, they can help to get a clearer understanding of urban phenomena. One of the quantitative models in order to evaluate and rank the areas is standardized score models and factor analysis. Therefore in order to achieve this important issue and social justice, classification of areas and identifying their development degree in terms of health indicators and determining the capabilities and shortcomings seem essential. This study also aims to analyze the development level of counties of Fars in terms of health infrastructure indicators using standardized scores pattern and factor analysis.

Method
This is a descriptive and applied study. In this study, using standardized scoring model and factor analysis the health level of counties of Fars has been investigated based on health indicators in 2011. Therefore, the geographic scope of the study is Fars and its statistical population consists of its 29 counties (Abadeh, Arsanjan, Estahban, Eqlid, Bavanat, Pasargad, Jahrom, Kharameh, Khorrambid, Khonj, Darab, Rostam, Zarrin Dasht,  Taghvaei & Avargani, 2007) and expert opinions (To collect the useful and deep information and so selected best indicator, 8 managers and faculty, as the key informants in field of study, were selected using purposeful sampling method), 10 indicators were considered as selected health indicators including active medical institutions to thousand populations ratio, number of beds in active medical institutions to thousand populations ratio, healthcare institutions to thousand populations ratio, public healthcare institutions to active healthcare institutions ratio, daily healthcare institutions to active healthcare institutions ratio, circadian healthcare institutions to active healthcare institutions ratio, the number of laboratories to thousand populations ratio, the number of pharmacies to thousand populations ratio, radiology centers to thousand populations ratio, and rehabilitation centers to thousand populations ratio. Data were collected using a data collection form developed by the researchers including questions on the counties' names, number of active medical institutions, available beds, number of healthcare institutions, number of public healthcare institutions, number of daily healthcare institutions, number of circadian healthcare institutions, numbers of laboratories, number of pharmacies, radiology centers, rehabilitation centers, and city population. Data were also collected by the Center of Statistics and Shiraz University of Medical Sciences. After completing the forms, the rank of city development was calculated using factor analysis and standardized scores through Excel 2010 and do SPSS.19, respectively. The method of calculation in these two methods is as follows: First, indicators are standardized in terms of the county based on standard score model. Factor analysis method is also a developed multivariate statistical technique performed to reduce and restructure the data. Using the correlation between data is the main foundation of this analysis based on which many variables can be grouped (Laskowski et al., 2010).
Factor analysis, which is a multivariate statistical technique, aims to summarize the data and tries to justify correlation patterns in the distribution of a random vector in terms of the minimum number of unobservable random variables called factors. This method investigates internal correlation of a large number of variables and finally classifies and explains them in forms of limited factors. Stages of its implementation are as follows: a) Selecting the appropriate variables b) Extracting factors c) Determining variables of each factor (interpreting the factor matrix) (Menke, 2012).
To determine the developmental gap in healthcare sectors among counties, five categories were considered www.ccsenet.org/gjhs including developed, moderately developed, averagely developed, less developed and undeveloped categories. After this stage, to determine the distances between the provinces in the five-level first the change in score range using "a" formula was obtained, then using "b" formula the distance between the categories was calculated, resulting in categorization of counties in five groups.

Results
Fars has a total population of 4596658, most of which live in Shiraz (1700687) Vol. 7, No. 1;2015 According to calculations done by the standard score method, the development coefficient of each county has been calculated. The results showed that the rate of development for the studied counties ranged from a maximum of 0.894 to a minimum of -0.941, so that Shiraz had the most and Rostam had the least rate among the others (Table 2). Based on a standardized scoring method according to the coefficients obtained, the studied counties were classified into 5 groups of developed, moderately developed, averagely developed, less developed, and undeveloped. A large number of counties (32%) were among the moderately developed and the least were among developed and underdeveloped groups (each 10%) (Table 3). Based on calculations carried out according to the factor analysis method, factor score of the counties studied ranged from a maximum of 3.861 to a minimum of 2.001. The same as standardized score method Shiraz had the most value and Rostam had the least value among other counties (Table 4).

Discussion
The first step to develop health sector and reduce the health gap among different regions is to achieve a relatively complete understanding of the health sector situation in those regions. Therefore, this study aimed to determine the level and extent of county development in the health sector in 2011 in Fars. In the model used the counties are ranked and also their development status is considered. To determine development level of the counties the standardized score model, five levels were considered including highly developed, developed, developing, poor and very poor.
Experience of the regional studies in different countries suggests that some areas compared to other areas of a country have a better development and growth. Therefore, if planners are able to identify factors affecting the development of the areas, then they can both benefit from the experiences of managers of different parts of the region and optimally allocate available funds (Girardi et al., 2012;Rosero-Bixby, 2004).
The results showed that in both methods Shiraz ranked first and Rostam ranked last in terms of development indicators for the healthcare indicators. The development coefficient variation in the standardized score method was 1.895 and in factor analysis was 5.862 indicating a large gap between the studied counties in terms of taking advantage of the health indicators. Based on the standardized score model, 3 counties (10%) were in less developed level, 10 counties (34%) were underdeveloped, 7 (24%) were averagely developed, 12 (42%) were relatively developed and developed. Hamouzadeh et al. (2013) ranked West Azerbaijan districts regarding utilization of structural indices of health care using Scalogram Analysis Model. In their study evaluating the general situation of counties of West Azerbaijan Province regarding utilization of total structural indicators of health, three counties were determined as developed and highly utilized counties including Mahabad, Naqadeh, and Urmia. Khoy and Bukan were known as relatively developed counties. Takab, Maku, and Miandoab were considered as averagely developed, and less developed counties include Salmas, Shahindej, Sardasht, Oshnaviyeh, and Chaldoran.
Sayehmiri performed a sturdy in order to rank health status of the cities of Ilam using numerical taxonomy technique and principal component analysis and considering 66 major indicators of health. The results showed that Ilam was the most developed and Mehran, Darrehshahr, Dehloran, Shirvan-o-Chardavol, Eyvan, and Abdanan palced in the following ranks (Sayehmiri & Sayehmiri, 2001).
Therefore, the differences in the studied counties are largely due to the differences in access to health indicators.
Although it was mentioned the differences between the different regions using different approaches also depend on the type of geographic area (socioeconomic development, etc), the distance to the provincial capital, the level in which the society is (levels of economic development and economic growth in the community), the performance of healthcare organizations in the region and confidence of local people to them, infrastructure facilities in the community, the extent of decentralization policies in the area, policies of workforce distribution utilities in university of medical sciences, and inability of the relevant units on competency and skills of staff. It can be also said that results of examining resource distribution status regarding the used model as a default in access and equity measurement in resource distribution can lead to development plans in this sector.

Conclusion
Health care indicators the same as other development indicators in third world countries have not been distributed in a balance form among geographical areas. Iran is no exception, and the gap is clearly seen in the development of these indicators in different provinces of Iran. In the present study, the rank and status of health sector development in provinces were examined.
The results show there is a relatively large difference among different counties in health sector, and most studied counties are not in a desirable level in terms of healthcare indicators. Only 10 percent of the counties were in developed status based on the model.
Generally, counties' ranking in healthcare sector provides relevant authorities with more accurate planning, identifying strengths and weaknesses, and priority of resources in accordance with needs of the province. In summary, the results showed that statistical methods are effective tools in ranking and determining status of development in the healthcare sector. The results of this study regarding the allocation of resources for the health sector would be useful for health planners and policy makers.
