Regional Disparities in the Distribution of Healthcare Workers: Evidence From Iran, Chaharmahal and Bakhtiari Province

A health care service is a prerequisite for sustainable development. This requires access to balanced health workers in different geographic areas. The first step is to identify inequality in access to health workers in different areas. This study is a descriptive study was carried out on the cities in Chaharmahal and Bakhtiari province. TOPSIS technique was used to rank the cities in terms of regional disparities in the distribution of health workers. The findings revealed that distinct disparities in the distribution of healthcare workers across Chaharmahal and Bakhtiari province. Shahrekord and Ardal cities were classified as 1st and 7th respectively. Policy makers should consider priority (regional planning, budget and resources allocation) according to the distribution of healthcare workers.


Introduction
A well-adjusted distribution of human resources is a step towards elimination of regional disparity (Shaykh Baygloo, 2012). Development and health are strictly associated to each other (Rafi'iyaan & Taajdaar, 2008). Health as an essential community part of national and international level plays a significant role in the welfare of individuals (Sayemiri & Sayemiri, 2001).
The studies have been mostly conducted on the use of economic and social indices and infrastructure development indices to classify different geographical areas, in terms of access to the indices (Poor Fathi & Asheri, 2010). Previously GDP and GDP per capita were used for assessing the development level. These indices do not reflect equality in the distribution of social services and healthcare services (Mahmoudi, 2011). Health as an significant social section of any nation plays a decisive function in the welfare of societies (Sayemiri & Sayemiri, 2001). Access to healthcare is a multi-dimensional concept (Paez, Mercado, Farber, Morency, & Roorda, 2010). This issue has been concern of public policy makers (Amaral, 2009;Comber, Brunsdon, & Radburn, 2011). Researches in most of regions demonstrated that particular regions have enjoyed the new services and facilities (Amini, Yadolahi, & Inanlu, 2006). Islamic Revolution exclusive consideration has been paid to the healthcare section (Ahmadi, Ghaffari, & Emadi, 2011).
Distribution of healthcare indices in the provinces and towns of Iran is heterogeneous (Taghvaei & Shahivandi, 2011). Similar to low and middle income countries, certain regions compared to other regions are accountable for the create national income (Mohammadi, Abdoli, & Fathi Biranvand, 2012). Hence, it is essential to describe the terms of equal distribution of healthcare facilities and designing an integrated plan to fix this problem .
This study was conducted using TOPSIS technique to assess the health workers access across the Chaharmahal and Bakhtiari province. Due to the multiplicity of criteria for comparison subjects, the use of other techniques will lead to problems in decision-making. However, these things do not occur in the TOPSIS technique. TOPSIS technique as a family member in a Multiple Criteria Decision Making (MCDM) are used to rank the various concepts of knowledge, due to the transparent nature, mathematical logic and haven't any operational issues (Zyaree, Zanjirchee, & Sorkhkamal, 2010). The aim of this study is to provide a clear vision from the status of Chaharmahal and Bakhtiari cities in terms of distribution of health workers.

Methods
This was a descriptive study for health system evaluation. The sample included all 7 towns of Chaharmahal and Bakhtiari province that is located at the center of Zagros Mountains. This province is limited to Isfahan from the east and the north, to Khuzestan province from the west, to Kohkilooyeh and Boyer Ahmad from the south and to Lorestan province from the Northwest. The city of Shahrekord is the center of Chaharmahal and Bakhtiari province. According to the SCI data, the growth rate (average annual) of the population of Chaharmahal and Bakhtiari is 0.86 have been calculated and its population percentage is 1.19. The numbers of 5 health workers indices were selected based on their availability at 2011 National Statistics Center's annual report as follows (Table 1). To assessing the development level, several quantitative techniques are available which depending the validity and reliability of the existing evidence and the skills of local authorities are employed to plan, organize and evaluate past information (Badri & Akbarian Ronizi, 2007). One method of grading the areas according to facility distribution is the TOPSIS technique. TOPSIS technique has gained significance as one of the MCDM techniques to rank the different concepts of numerous branches of science, the most important reason being it's clear, mathematical logic and the practical problems associated with it. TOPSIS technique is done in the following stages ( The classifying is done based on the decreasing values of , means that the highest is considered as the most developed, and the lowest as most Underdeveloped.

Results
The aim of the current paper is to describe the regional disparities in the distribution of healthcare workers in Chaharmahal and Bakhtiari cities. Chaharmahal and Bakhtiari towns were compared in terms of access to healthcare workers using TOPSIS technique. To offer a clear vision from the status of Chaharmahal and Bakhtiari cities, 7 towns were measured and ranked into three classified (Table 1). The results show that the highest and lowest degrees of development based on TOPSIS technique in Chaharmahal and Bakhtiari province, belonged to Shahrekord (0.756) and Ardal (0.104) respectively. Findings show that in terms of access to healthcare workers, Shahrekord, Borujen and Farsan can be regarded as developed, while Koohrang and Kiar are categorized as developing. Lordegan and Ardal can be regarded as underdeveloped. The findings illustrate a gap between Chaharmahal and Bakhtiari towns.

Discussion
Accessibility of healthcare services is one of the most important indicators for developing countries (Zarrabi & Shaykh Baygloo, 2011). The public scarcity of healthcare workers in low-middle income countries, there is a general understanding that enormous in country disparities exist in the distribution of healthcare workers (Munga & Maestad, 2009). In this study we tried to examine the regional disparities in healthcare workers across Chaharmahal and Bakhtiari province. 5 indices were selected and analyzed using TOPSIS technique.
Healthcare workers should be accessible for all people in the Farthest and poorest parts of the country; however some services, such as specialist only delivered at larger cities and cover the suburbs. Smaller cities with a population lower than the service for population threshold only can be provided with mobile services or only on special weekdays (Zarrabi & Shaykh Baygloo, 2011).
The results of this study show that access to healthcare workers was very different among people in the Chaharmahal and Bakhtiari province. 42.8 % of the cities (Shahrekord, Borujen and Farsan) were in the level of development; 28.6 % (including two cities: Koohrang and Kiar) were in developing level, and 28.6 of cities (including two cities: Lordegan and Ardal) were underdeveloped in terms of their access to healthcare workers.

Conclusion
In order to decrease gap of access to health workers between the cities and equitable distribution, concentration on development of health indicators in poor cities (such as Lordegan and Ardal), is recommended. Furthermore, it is suggested that in the first stages of city development, authorities need to focus on short term policies and programs which could result in expansion of critical health workers and equity in access and authorities may pay attention to the development of necessary services in developing and deprived cities over a medium and long term plan (5-10 years).
