The results of this study showed that in half of the first-level health services, including psychology, counseling for high-risk behaviors and diabetes care, the first decision made by most of the individuals was to refer to specialist physicians, which indicated an inappropriate health-seeking behavior. The results of the studies by Musah and Toyin Kayode in Nigeria (
15), Van der Hoeven et al. in Africa (
16), Pourreza et al. in Tehran, Iran (
17), Borhaninejad et al. in Kerman, Iran (
18), Ebadi Fard Azar et al. in Isfahan, Iran (
11) and Rasoulynezhad et al. in Kashan, Iran (
6), which showed that the most frequent referrals were to specialist physicians, confirm the findings of our study.
But what is the reason for the preference for referring to specialist doctors? Borhaninejad et al. found that higher quality of services and greater trust were the reasons for more referrals to specialist doctors (
18). Some individuals studied by Van der Hoeven et al. described the reasons for referring to more specialist levels as follows: “because I was not good at all,” and some others said: “Health clinic services are convenient for monthly care of non-communicable diseases such as hypertension” (
16).
In the present study, the mean score of perceived quality of first-level services given to health houses/health posts/family physician posts was 3.45 out of 5, which was relatively good, but the lowest quality score was related to the staff manner dimension. Another reason for unnecessary referrals to specialists was the public view; that is to say, health houses/health posts were only suitable for vaccination, and family physicians were only suitable for simple illnesses such as a cold. Indeed, this view is affected by the structure of the health service supply system because health centers and health posts in urban areas are currently abandoned in the network system. The lack of attention of authorities reduces the credit of these centers (
19). In villages, local educated forces (Behvarz) have been trained for health houses, but there are no similar forces in cities (
9).
On the other hand, the family physician program being executed cannot be called a real family doctor program since one of the most important duties of family physicians is to provide basic health care services, but in this program, no separate and explicit definition has been provided for the health care of target groups, and referrals to family doctors are so numerous that they fail to accomplish their main duties, that is, monitoring and promoting health (
20). Meanwhile, confused people are looking for a quality service center for their health needs, and they will ultimately refer to specialists or subspecialists on the basis of their own discretion. To address this, the opinions of the service recipients should be taken into account during the delivery of the first-level services, and even better evaluation of services by the public should be made. Damari et al. believe that patients who are satisfied with the services will not tend to circumvent the referral system. Thus, health centers should be rich in personnel, well-equipped and sufficiently accessible to people at appropriate times throughout the day (
20).
In our study, the first decision made by most people was to not seek specific health services in terms of nutritional counseling. The results of the study by Olasunbor et al. on nutritional health-seeking behavior in Nigeria showed that 85.2% of the subjects had visited a health care center at least once within the previous month (
21). This was not consistent with the results of the present study. The results of our study in terms of receiving services in case of simple illnesses, as well as care for the elderly and patients with hypertension, showed that the first decision of most people was to refer to the family physician’s office, which is indicative of an appropriate health-seeking behavior.
However, regarding these services, the respondents stated that they had not received the services in the form of continuous and comprehensive health care, and only in the event of a disease their first decision was to refer to the family physician's post. The study by Borhaninejad et al. on utilizing health care services by the elderly in Kerman, Iran, showed that specialist doctors had the highest number of visits (
18), which was not consistent with our study results in terms of the first decision about elderly care. It seems that the family physician plan in Shiraz, Iran, has been able to provide an appropriate coverage for the elderly to receive care services.
A survey by Bovet et al. on health care utilization for hypertensive patients in Tanzania showed that 63% of the people used public health centers (
22). These results were consistent with those of our study in terms of the fact that the participants had referred to the same first-level services.
As far as counseling for high-risk behaviors is concerned, the important point was that nearly 70% of the individuals said they never needed to receive such services. Perhaps, people’s lack of awareness about diseases like AIDS and hepatitis, as well as their feeling about incurability of these diseases may cause social stigma to those in need of such services, and this leads to lack of referral to the service centers, or even if they refer, they will hide their referrals. In terms of counseling for nutrition and psychology, the majority of people who had not used the services provided by the formal sector said the reason for their non-referral was economic problems.
Economic resources are among the empowering factors of the Andersen model and the factors needed for enabling people to access health care services. One way to receive these services is to subsidize low-income people by the government. However, community health centers offer services such as nutritional and psychology counseling free of charge to those referred by family physicians, but the information about the delivery services was so poor that almost nobody knew about such health care services.
Findings showed that in more of the first-level services, including simple illnesses, counseling for high-risk behaviors, elderly care and hypertension and diabetes patients, the major reason for not using formal services was that these problems were not taken seriously. Regarding preventive and screening services, unlike health care or rehabilitation services, since the illness or disability has not appeared yet, people do not consider receiving care seriously, and this is the time when educating and directing the attention of the individuals toward health issues seems necessary (
23).
In many studies such as those by Borhaninejad et al. in Kerman, Iran (
18), Pourreza et al. in Tehran, Iran (
17), Danso-Appiah et al. in Ghana (
24) and Kolola et al. in Ethiopia (
25), people stated that their lack of referral to receive health care services despite having illnesses was due to the unimportance of their illnesses and economic problems. However, Kavosi et al. did not show any inequality in the actual amount of outpatient service utilization in Shiraz, Iran (
26).
The family physician program in Fars province was implemented in July 2012. Prior to March 2017, referrals to specialists had to be made only through a family physician referral form, but since then, due to pressures on policy makers, referrals to specialists became possible outside of the referral system and without referring to the family physician, but with a little higher charge. Since the referral system became non-mandatory during conducting this study, a comparison was also made with regard to the impact of mandatory referrals on households’ decisions. Findings showed that the mean score of adherence to the referral system by the subjects under study at time of mandatory referral system was higher than their score at the time of optional referral system. The mandatory referral system was one of the control mechanisms that prevented the direct referral of patients to specialists in order to strengthen the first level of contact, and when the referral system became optional the mean score of adherence to it declined.
The results of this study revealed that in case of simple illnesses, the factors such as age, educational level, place of residence, household income, having health insurance, type of health insurance and mandatory or optional referral system influenced the use of services, but the factors such as gender, marital status, and health status did not play any roles in the use of services. The study by Kuuire et al. on health-seeking behaviors during illnesses showed that age, health status and educational were effective on individuals’ behaviors (
27). The results of their study were not consistent with those of our study in terms of the impact of health status.
In our study, nutritional counseling was influenced by educational level, marital status, household income, household residence, health insurance, type of insurance, health status and referral system. However, receiving these services had no significant relationship with gender and age. The results of the study by Olasunbor et al. in Nigeria, which was conducted on nutritional health-seeking behavior in Nigerian, indicated that gender, age, educational level and income had an impact on the health-seeking behavior in terms of nutrition (
21). Quinn et al. in Georgia, US, showed that age, income and gender affected the nutritional health-seeking behavior (
28). The results of their study were not consistent with those of our study in terms of the impact of age and gender.
The results of the present study presented that using psychological services had a significant relationship with gender, educational level, income, residence, having health insurance, type of health insurance, health status and referral system. However, psychological services had no significant relationship with marital status and age. In a study on the factors affecting the use of Canadian mental health services, Fleury et al. found that gender and income had an impact on the use of psychological services (
29). The results of their study were consistent with those of our study.
The results of our study showed a significant relationship between counseling about high-risk behaviors and income, residence, having health insurance, type of health insurance, health status and referral system, but no significant link was noted between counseling about high-risk behaviors with gender, educational level, marital status and age.
The results of this study showed that educational level, marital status, income, residence, type of insurance, health status and type of referral system played a determining role in adherence to the referral system, but factors such as gender, age and having health insurance did not affect the referral system.
According to the results of this study, the factors including gender, marital status, age and residence played a determining role in the perceived quality of primary health services, but educational level, income, having health insurance, type of health insurance, health status and type of referral system did not have any effects on the estimated quality of primary health care services. A study by Alibabaei et al. was conducted to determine the quality of family doctor team’s services from the viewpoint of the clients in Ajabshir showed that women had higher satisfaction with most items than men. The highest satisfaction was found among the 40 - 49 age group and the single people. There was no significant relationship between satisfaction and educational level (
30). This finding was consistent with our results in terms of all items, except for the effect of marital status. The study by Fallahi et al. on the satisfaction of clients with family physicians in Jiroft, Iran, showed that gender and insurance did not affect the individuals’ satisfaction, but the people aged 45 - 60 years, married ones and those with low educational level had estimated the quality of the services higher (
31). The results of that study, except for the two factors of gender and educational level, were consistent with those of the present study.
The results of our study showed a significant relationship between the use of elderly care and household income, the closest center to the household residence and residence, but there was no relationship with the current residential status and type of referral system. In the study by Park in Korea, income also influenced the use of elderly care services (
32).
In the present study, receiving hypertension care had a relationship with income, the closest center to the household residence and the house location. However, hypertension care had no relationship with the current residential status and type of referral system. The results of the study by Bovet et al. showed that income did not affect the use of services by Tanzanian hypertensive patients (
22), and it was not consistent with the results of our study. This inconsistency can be attributed to the time of study, study location, socio-cultural factors, demographic characteristics of the population studied, access of different communities to various locations and the quality of service provision. The results of the study by Ham and Lee on the use of health services by South Korean hypertensive patients also showed that the place of residence had an impact on the use of health services (
33).
According to the findings of this study, regarding diabetes care, the closest center to the household’s residence and the place of residence had a relationship with using these services. Nonetheless, housing status, household income and type of referral system did not affect the first decision made for this kind of care. The study carried out by Inche Zainal Abidin et al. in Malaysia also indicated that the closest center to the place of residence had an impact on the treatment-seeking behavior of diabetes patients (
34).
4.1. Conclusions
The demographic characteristics and attitudes of individuals towards the existing services have a significant effect on their willingness to reuse those services at the health care centers. Therefore, managers and policy-makers of the system should focus their efforts on providing desirable services and, consequently, changing the way households view the services and increasing their satisfaction with the existing services.
