The health status of the community, residents' satisfaction with the health services, and protection against financial risks are the main purposes of evaluating the health system's performance (
1). However, benefiting health services leads to catastrophic health expenditure, that is, can make households pay part of their income directly or out-of- pocket (OOP), which renders the large number of households in poverty (
2).
Direct payments or OOP payments are the health care financing resources. The fact is that this approach is the worst strategy to meet the health financing need, from the view point of protection against financial risk and equity (
3). These types of payments have negative impacts on health care productivity and health, as well as important effects on living standards. The welfare of a community is under the influence of unmet medical costs and direct payments. Households may borrow to cover the unexpected medical expenditures, but they will run into long-term debt (
4). Because of the impact of OOP payment on living standards and well-being, the World Health Organization (WHO), in 2000, declared the equity index as one of the key variables in measuring the health services systems performance (
5).
This index is to the extent important that, the WHO has given it a weight of 25% to calculate the general index of health performance (
6). However, part of the households’ income in all societies is spent on health care. The rate of its contribution and distribution in societies indicates the imposition of the financial burden of health care on communities (
7). Iran's health system is experiencing an epidemiological transitional period and due to the life span increase of individuals and facing the diseases of the industrial world (lifestyle changes, obesity and related diseases, hypertension, cardiovascular events, traffic accidents, cancers, and other chronic diseases), it has been under a double burden of disease (
8). These diseases not only threaten the live and well-being, but also endanger financial security. In diseases, such as cancer, the medical cost of OOP can be unaffordable. The medical costs for cancer patients impose rigorous burdens on governments and patients. Studies indicate that the cancer patients, who face the OOP payment, potentially affect their financial performance (
9).
In addition, the disease can impair a person’s ability to function and perform tasks, at home and work, and even it influences national production. Cancer disease due to its potentially life-threatening consequences and illness period can be life-threatening and change the person’s life condition. Breast cancer with the highest prevalence rate is the most important health concern in women. Globally, 2.3 million women were diagnosed with breast cancer and 685 000 deaths in 2020. As of the end of 2020, there were 7.8 million women alive, who were diagnosed with this disease in the past 5 years, making it the world’s most prevalent cancer (
10).
In Iran, breast cancer is the most common cancer in women and comprises 21.4% of all cancers in women (
11). The onset of breast cancer in Iran is 22 per 100,000 and the prevalence rate is 120 per 100,000 women aged 15 to 84 years (
12). However, the global survey reveals an elevation in the incidence of breast cancer, but a faster rise in developing countries (
13). According to the previous studies, the incidence of breast cancer in Iranian women occurs 10 years earlier than the western women (
14). Data indicate that 70% of breast cancer patients in Iran die early due to delay in the diagnosis and being in the advanced stages of the disease (
15). In 2013, Iran National Cancer Control was developed with a strategic planning approach that consists of 4 main processes and 7 support processes. Also, this program has been able to relatively achieve its short-term goal, but to achieve the expected outcomes, it is essential to strengthen the governance structure and the commitment of health policy makers to implement this program (
16). However, benefiting effective health care is poor for breast cancer patients, who live far from cancer treatment centers. Though effective treatment is important for the physician and patient, the financial problems and the medical cost imposed on the patient, delay the treatment process, because the patient may not cooperate, especially those who live far from the medical setting. OOP payment for health care prevents access to medical services that influences the health and quality of life, and leads to the financial shortage for the other expenditures (
17).
In general, breast cancer costs around 2 to 3 thousand dollars per month in the world (
11). Treating early-stage breast cancer is more cost-effective than late-stage disease. In Asia and Africa, treatment of stage I, II, or III disease costs less than 390 dollars per disability-adjusted life years (DALY) averted, whereas treatment of stage IV disease costs more than 3500 dollars per DALY averted (
18). Various studies have shown that direct health care costs impose the greatest financial burden on the patient and society. A study by Bazyar et al. on cancer patients admitted to the cancer center of Imam Khomeini Hospital in Tehran in 2010 showed that, on average, 91% of the total OOP payment of patients was related to medical direct costs and the share of non-medical direct costs, from out of total costs was only 9%. Bazyar et al. showed that the average OOP payment for the medical direct care costs was about 38.9 dollars. However, the average cost of non-medical direct payments was estimated to be around 23.9 dollars (
19).
In Iran, financial resource for health care is provided in part by the government and insurance agencies. It is important to know what services expose the patients to higher OOP payment and what patients face the burden of breast cancer treatment costs. Therefore, the authors decided to identify the rate of these OOP payments in breast cancer patients to find ways to protect them from the negative effects of this condition and to identify the financial burden on these patients.
