The findings of this study showed that the timing of preconception care, prenatal care, and the first postpartum care healthcare services were significantly different in the suburbs and urban texture of Qom in a way that such caring services took considerably longer in the suburban areas. However, the timing of healthy prenatal care healthcare services was not significantly different. It needs to be mentioned that in one component of reproductive health care (fertility consultation), there was a significant difference because this type of service is highly dependent on the social status of the referrers. As for the components of prenatal care healthcare services, although there was a significant difference between the two city areas in terms of the total timing, it was only the nutritional healthcare service that was significantly different between the suburbs and urban texture. The prediction and analysis of the healthcare costs could help managers reach maximum efficiency via exact preplanning and budget distribution (
14). Numerous studies have been conducted in Iran and other countries in this regard. For example, Narayanasamy et al. conducted a timing and motivational study among 19 midwives and health supervisors in six healthcare centers in Pudochery, India, during year 2018. The participants themselves recorded their own daily activities on a time-measuring sheet for six days. Their timing plans showed that they spent half of their time giving healthcare services to mothers and children (
15). In this study, the timing of the services was done by direct supervision and via a chronometer and the total timing as well as the timing for each package component was measured in through a valid and standard procedure. In Narayanasamy et al.’s study, however, timing was measured and recorded by the participants themselves during work days. In another study conducted during year 2016, Tani et al. studied the timing of the daily activities of healthcare staff in a four-week period in three rural areas in Tanzania. Their results revealed that in each eight-hour working day, 59.5% of the time was spent for healthcare services and other types of relevant activities. In total, 27.8% of their activities belonged to home-nursing, 33.1% to healthcare education, and only 12.3% to the direct care for the patients. Regarding other types of activities, 7.8% belonged to registration and 2.5% to supervision (
16). The current study showed that the required time for performing all the components of motherhood and reproductive health care compared with Tanzania was longer, and the healthcare working staffs provide healthcare services in all their working shifts in Iran. Given the significant differences in a number of investigated healthcare services, it seems that it is better to allocate the working staffs based on the real needs of the centers, because the working staffs are the most important asset of any healthcare system. Thus, their complete satisfaction with their job is of utmost importance (
17). Therefore, it is essential for managers to calculate the working load of the personnel and specify the required ones in each center based on real needs rather than based on the mere population of that area. Moreover, they can improve the general conditions of these healthcare centers by a fair distribution of personnel. Otherwise, the working staffs in some centers may claim that there is a shortage of required staff, the centers are crowded with referrers, and the job is extremely difficult for them to handle. On the contrary, some other centers may state that they are facing a shortage of referrers and are overcrowded with the staff. Hence, in both situations, there is a lack of satisfaction and a continuous demand to either increase or decrease the number of personnel. If the management pays due attention to the working load of the personnel, they will become more confident about the satisfaction of their staffs with their activities in line with the goals of the organization. By doing so, the personnel of healthcare centers receive positive feedback from the management and are motivated to perform their duties (
8). Similarly, a scientific management of the working load can increase efficiency yet decrease the wasting of time and studies. It can also motivate the working staffs to perform their duties (
8,
10,
18). On the other hand, lack of enough working staffs inflict a heavy load on the personnel and causes tensions between the personnel and referrers. Thus, removing or decreasing such overbearing pressures can directly improve the quality and quantity of healthcare services and the degree of satisfaction of the referrers. In one study conducted in the Iranian context, Zeraati suggested that officials and managers need to adopt measures to manage their personnel appropriately and support them socially so that the working tensions are reduced as much as possible (
19). Likewise, comparing the degrees of satisfaction by patients before and after the implementation of health system reform plan, Hashemi et al. found that patients’ satisfaction levels regarding healthcare clinical services had decreased after the implementation of this reform plan because less time had been devoted to examination and consultation of the patients (
20). As a result, given the threatening factors in the realm of working staffs and the role they play in keeping patients satisfied with the healthcare services, there is a paramount need for the healthcare centers’ personnel to receive necessary supporting packages (
21). One of the limitations of this study was the presence of the researcher (observing supervisor) for measuring the time that can affect the usual, natural performance of the participants. Nevertheless, this innate limitation is always present in timing studies. Another limitation was that the timing of providing healthcare services may be different among healthcare personnel based on their personal merits, experience, and conditions. However, the current study attempted to control such a factor by including only supervisors, who had the same academic degree, speed, and quality of service. Overall, this study was not only helpful in having an optimal management of resources and in decreasing the costs, yet it can also be used as a tool to plan more appropriate policies in the health system reform plan. However, since the purpose of this study was the timing of reproductive health services, the researchers suggest that the quality of primary health services, such as maternal health care, should be assessed by future studies.
