Background:Cancer poses a serious threat to one’s health, which caused significant economic burden on the family and society. Poor availability and affordability resulted in some essential medicines failing to meet the basic health needs of this group of patients. The objective of this study was to evaluate the availability, prices and affordability of 32 anticancer essential medicines in Hubei Province, China.
Methods: Data on the availability and price related information of 32 essential anticancer medicines in the capital and five other cities of Hubei Province were collected. A total of 28 hospitals were sampled, which included 13 tertiary hospitals and 15 secondary hospitals. We used the standard methods developed by the World Health Organization and Health Action International to compare the differences in drug price, availability and affordability between secondary hospitals and tertiary hospitals.
Results: Overall, the availability of medicine was higher in tertiary hospitals. The average availability of originator brand (OBs) was 13.70% (tertiary hospitals) VS 6.67% (secondary hospitals), and lowest-priced generic (LPGs) was 62.83% (tertiary hospitals) VS 42.92% (secondary hospitals). The MPR value of most sampled medicines in secondary hospitals were less than 1. In contrast, the MPR of Cytarabine (17.15), Oxaliplatin (12.73) were significantly higher than the international reference price. The top three OBs’ total expenses for 30-days treatment were Irinotecan, Oxaliplatin, Bicalutamide. Further, their affordability was relative low, as the costs for one course using these medicines were much higher than 20% of the minimum family monthly income.
Conclusion: Though the “Zero Mark-Up” and “Centralized procurement policy of anti-tumor drugs” policies have been implemented in China, the availability issue yet to be addressed. High price and low affordability were the major barriers to the access of essential anticancer medicines. Measures should be taken to provide sufficient, available and affordable medicines to patients in need.
Introduction
Cancer has become a serious health problem, which contributed to severe burden of disease and even death (Zhu et al., 2019). A total of 9.6 million deaths due to cancer diseases were reported worldwide in 2018 (Erratum, 2020). China accounts for 21.0% of the worldwide new cancer cases, and total of 22.96 million Chinese residents died of cancer (Shaoqing, 2019). At present, anticancer medicine is a core component of treatment, but barriers to receiving cancer therapy such as high price of anticancer medicines and poor availability were yet to be solved (Smith et al., 2014). These problems may be related to medical information asymmetry and the distribution of responsibilities between the drug purchasing sector and the patients who bear the cost restrict competition in the market (Hasan et al., 2019).
Essential medicines are the indispensable drugs that satisfy the priority health care needs of the population. Meanwhile, they are selected with due regard to rational use and equitable access on their efficacy, safety and comparative cost-effectiveness (Beran et al., 2018). To better meet the necessary treatment needs, the Chinese government attaches great importance to the development and implementation of the Essential Medicine List (EML) (Khanal et al., 2019). In 2018, China re-adjusted the national EML, and increased the growth rate of oncology drugs by 35%. In terms of cancer treatment, the 2018 edition of the “National Essential Medicine List” added five kinds of non-targeted drugs, including Ifosfamide, Gemcitabine, Pingyangmycin, Capecitabine, and Letrozole (Dong et al., 2020). The supplementary medicines can greatly alleviate the burden of cancer treatment.
In addition, the price of 14 anticancer drugs fell by an average of 14.95% in China, as the National Medical Security Bureau issued centralized drug purchase measures and accelerated the pace of medical insurance drug-price negotiation (Chinese, Government, 2018; Kaiyue et al., 2021). Despite medical insurance policy system was improved, dozens of targeted anticancer drugs have been included in category B (local medical expense settlement institutions could bear approximate 55–70% of the patients’ cost of anticancer drug) (Kunhe et al., 2017), due to the unbalanced distribution of medical resources and the per capita financing guarantee level of China’s medical insurance is still relatively weak, the total amount of medical insurance controlled by provinces and hospitals has limited funds allocated for health care, as a result, many cancer drugs still have high treatment costs even after medical insurance promotion policies are implemented (Yf).
Recently, most of domestic studies on essential medicines focused on antibacterial drugs and medications for chronic diseases (Wu et al., 2018; Dong et al., 2020; Liang et al., 2020). Their study can reflect the common problems in the availability and affordability of essential drugs in China, however, the question regarding whether it is the same case for anticancer still awaits further investigation. Therefore, we investigated the price, availability and affordability of anticancer drugs in 28 public hospitals in Hubei Province, in order to explore the factors influencing the shortage of medicines and rapidly increasing health expenditure, and accordingly, propose corresponding strategies to the government and pharmaceutical management institutes.
Methods
A cross sectional survey was conducted from November 2018 to January 2019. Data were collected on medicine price, availability and affordability information from tertiary hospitals and secondary hospitals in six cities of Hubei Province following WHO/HAI standardized approach and Health Action International (HAI) (Khuluza and Heide, 2017).
Study Design/Sampling
Area Selection
We selected six cities as survey regions in Hubei Province by referring to the Gross Domestic Product (GDP) in 2018, according to which, we selected three cities in high-income (Wuhan, Yichang, Xiangyang) and low-income (Huanggang, Xianning, Suizhou) areas, respectively (China YearBooks, 2019). Hospitals were selected using a multistage clustered approach. Firstly, we chose the best tertiary hospital as the survey anchor (it ranked the first in this area) in each city (for instance, Tongji affiliated hospital of Tongji medical college was selected in Wuhan city). After identifying the survey anchor, we selected at least one secondary hospital pharmacy, which was closest to the anchor hospital. Since Baidu maps was used to select secondary hospital pharmacies from a list of all facilities within a 3-h drive from each survey anchor hospital. But if back-up outlet was less than 50% of the medicines on the Medicine Price Data Collection form, then we would select another secondary hospital pharmacy in the sample list. Last, a total of 13 tertiary hospitals and 15 secondary hospitals in the public sector were selected from six cities in Hubei Province. As anticancer drugs belong to the category of key controlled drugs in China, hence, they are mainly available in secondary and tertiary hospitals of China. So we don’t include retail pharmacies in our investigation.
Medicine Selection
A total of 32 medicines were included in this survey, referring to 2017 WHO Essential Medicine List (WEML) and 2018 National Essential Medicine List (NEML). Considering the common acute and medication conditions in tertiary and secondary hospitals of Hubei Province, we divided the selected medicines into two parts according to the available data collected from the sample hospitals. Firstly, the intersection area of anticancer drugs were from the WHO Essential Medicine List and National Essential Medicine List, which included 20 core essential medicines. Then, additional 12 sample drugs were also included in this survey list as supplementary according to oncologist’s recommendation and the actual needs of local hospitals. For each medicine in the survey, data were collected for two medicine types: the originator brand (OBs), and the lowest-priced generic (LPGs) equivalent found at each hospital.
Data Collection
With the aid of skilled pharmacy present, trained investigators visited the pharmacy department of the sampled tertiary and secondary hospitals. They collected information regarding the cost and availability using a standardized data collection form. At the end of each day, two students would enter the data into a designed MS Excel Workbook provided as a part of the WHO/HAI methodology (Eden et al., 2019; Saeed et al., 2019). The items included in the standardized form were as follows: basic information of the facility (hospital name, hospital level, survey date), information of the medicine (medicine in stock in the hospital on the day of data collection, yes or no), dosage, strength, medicine type (OB/LPG), and the retail price at the time of survey (Table 1).
Patient and Public Involvement
It was not possible or appropriate to involve patients or the public in the design, data collection, reporting or dissemination plans of this analysis.
Assessment of Availability
The availability of anticancer medicines was reported as the percentage (%) of medicine outlets in which the information was documented by surveyed facilities on the day of data collection. Availability was classified as 4°; Absent: 0 of facilities, suggested that we could not find these medicines in the facility; Low: < 50%, these medicines were rarely purchased; Fairly high: 50–80%, these medicines were found in several facilities; High: > 80%, most institutions sold these medicines. In addition, mean percentage availability of OBs and LPGs were calculated for the investigations (Zhu et al., 2019).
Price Assessment
In order to make standard comparisons, price was evaluated by median price ratio (MPR) according to WHO/HAI approach, which is the ratio of median price of individual medicine obtained during the survey (Dong et al., 2020). Moreover, we used Management Sciences for Health (MSH 2015) International Drug Price Indicator Guide as the source of reference prices. MPR was calculated using the formula given below: Median Price Ratio (MPR) = Median local unit price/International reference unit price. It can provide a more intuitive data presentation for drug price monitoring: when the value of MPR is less than 1, it indicates that the price of the drug under investigation is lower than the international average standard. In other words, the price control is efficient. The value of MPR between 1 and 2 indicates that the drug price is acceptable; if MPR>2, this means that the drug price level is high and needs to be contained (Guan et al., 2018).
Affordability
In general, the total cost of the unit treatment for chronic diseases with the standard dose of the drug is equivalent to 1 month’s working days (daily wages) of the lowest paid non-technical government employee that enables him/her to purchase the standard course of cancer treatment. However, the duration of anticancer therapy may be longer. Moreover, the price of many anticancer drugs is too expensive, which causes heavy economic burden for cancer patients. Thus, with the aim to precisely assess the affordability, we used the approach proposed by Khatib and Sarwar (Khatib et al., 2015; Sarwar et al., 2018): if the total expenditure of medicine in 30 days accounted for 20% or less of the minimum family monthly income, it was regarded as affordable (Eden et al., 2019). The calculation formula was:
Results
We calculated the availability of originator brands (OBs) and lowest priced generics (LPGs) across the 32 anticancer medicines. In this survey, 92.43% OB was unavailable overall, and 10 OBs of 32 medicines were not available in tertiary hospitals nor secondary hospitals. The top three percentage availability of OBs in tertiary hospitals included Bicalutamide (47.62%), Methylprednisolone (38.10%) and gefitinib (28.57%). In tertiary hospitals, the average availability of OBs was 13.70%. In contrast, the mean availability of OBs was 6.67% in secondary hospitals (Table 2).
For LPGs, overall, the mean availability of surveyed medicines was 40.88%, and the mean availability of LPGs was 38.84% in tertiary hospitals, and 42.92% in secondary hospitals (Table 2). Besides, Oxaliplatin and Gemcitabine were maximal for 61.90% in tertiary hospitals (Figure 1). Two medicines with the highest availability in the secondary hospitals were Cyclophosphamide (93.33%) and Oxaliplatin (93.33%). Nevertheless, most LPGs were available in secondary hospitals (Figure 2). In general, the availability of the selected medicines in tertiary hospitals was higher than that in secondary hospitals.
Table 3 illustrates the median price patients paid and MPR in tertiary and secondary hospitals for 32 anticancer medicines in Hubei Province. The results showed that the overall price of medicines varied from RMB0.49 to RMB2290.12. In total, the median patient prices of 4 OBs were over double the IRP. The median patient prices of OB for Oxaliplatin (RMB2290.12) ranked first. Especially, its MPR was 12.73 times higher than the international reference price (IRP)from MSH. Furthermore, the MPR of 3 OBs were more than double that of IRP in tertiary hospital: Cytarabine (MPR = 17.15), Ifosfamide (MPR = 2.30), Paclitaxel (MPR = 2.81), respectively. The MPR value of sample medicines in secondary hospitals were less than 2, except Letrozole (MPR = 3.26). Additionally, the median patient prices of most LPGs were in line with IRP standards.
TABLE 3. The median patient price and MPR of anticancer medicines in tertiary and secondary hospitals in Hubei Province.
In order to compare the difference of drug availability and MPR value between secondary and tertiary hospitals, we made 4 scatter plots of the availability and MPR value of 32 anticancer drugs (Figure 3). In tertiary hospitals, for OBs, two points located in the upper left area of the graph, which were cytarabine and oxaliplatin, whose MPR was more than 10 times. However, their availability was quite low. The medicines with higher availability of OBs were gefitinib, Bicalutamide and Methylprednisolone with low MPR. For LPGs, Vincristine had the highest MPR value (3.25), and its availability was low. Eight medicines had fairly high availability with acceptable MPR value (MPR of 1 or less is interpreted as efficient procurement in the public sector) (Mendis et al., 2007; Kasonde et al., 2019).

(B) Scatter plot of OBs availability and MPR in secondary hospitals. (C) Scatter plot of LPGs availability and MPR in tertiary hospitals. (D) Scatter plot of LPGs availability and MPR in secondary hospitals.
In secondary hospitals, for OBs, only seven drugs with MPR value could be obtained. Figure 3 indicates Letrozole with high availability and MPR. Only Capecitabine’s MPR is acceptable. For LPGs, 11 medicines were highly available. Moreover, 21 drugs with MPR value were included. The result also showed that these eight medicines: Irinotecan, Methotrexate Sodium, Methylprednisolone, Mycophenolate Mofetil, Tamoxifen Citrate, Bicalutamide, Tacrolimus, Ondansetron were out of the acceptable range (MPR of 1 or less).
Table 4 shows the affordability of the anticancer medicines based on the duration of treatment. Overall, the mean affordability of the studied medicines was 2.89. For 31 LPGs, the mean affordability value was 1.79, which was within normal range. However, for 14 OBs, the mean value of affordability was 5.29. Further, irinotecan (13.89) and oxaliplatin (11.91) induced large payment burden, as the cost of 30 days dosage was higher than 10 times of 20% household minimum monthly income. In the surveyed hospitals, the affordability of 50% (7/14) of the OBs exceeded the mean affordability value (5.29), and 22.58% (7/31) of LPGs was over the average affordability.

Figure 4 shows that the monthly medicine expenditure of 3 OBs (Irinotecan, Bicalutamide, Oxaliplatin) exceeded 4000 RMB, and the cost of five medicines (Paclitaxel, Methylprednisolone, Mycophenolate Mofetil, Cytarabine and Capecitabine) were within 2000–4000 RMB. For LPGs, the 30 days treatment expenditure of four medicines (Irinotecan, Methylprednisolone, Gemcitabine, Fluorouracil) were over 2000 RMB, and the cost of most of the rest medicines were around 1000 RMB.

Discussion
Availability of Surveyed Medicines
The study evaluated the availability, price and affordability of 32 anticancer medicines in Hubei Province by using the WHO and HAI standard methodology. After investigating 13 tertiary hospitals and 15 secondary hospitals’ essential drugs, overall, we found that 7.57% of OB and 40.88% of LPGs were available in Hubei Province, China. The findings are similar with prior surveys in developing countries (Khuluza and Haefele-Abah, 2019; Saeed et al., 2019; Lambojon et al., 2020). Amna Saeed found that the overall availability of surveyed medicines in public sector was 6.8% only for OBs and 35.3% for the LPGs in Pakistan. In Philippines, the mean availability of surveyed medicines in the public sector was 1.3% for OBs and 25.0% for LPGs (Rui et al., 2019). They also found that most of the OB medicines were produced by large international manufacturers. Due to the lack of effective external supervision and approval for the OB medicines, price leading and brand premiums led to the relatively higher price.
Compared with secondary hospitals, the availability of surveyed medicines were higher in tertiary hospitals. Since radiotherapy and chemotherapy of tumor are very professional and expensive, they are mostly concentrated in large specialized hospitals or departments of tertiary hospitals, which contributed to the higher availability (Rui et al., 2019).
In general, the price of the OBs was high because of its core patent right of drugs, which endowed the original drug enterprises with a monopoly position (Babar et al., 2019; Zhu et al., 2019). However, LPG can be used as a competitive product to make up for its lack of accessibility (Abdel Rida et al., 2019). Especially in low and middle-income countries, hospitals will take into account the actual purchasing power of patients, and appropriately reduce the inventory proportion of OBs in hospitals (Dorj et al., 2018; Guan et al., 2018). The findings of our study showed that the availability of some medicines was relatively high, including Gemcitabine, Etoposide, Oxaliplatin, Cyclophosphamide, Tamoxifen, the underlying reason may be that these medicines could achieve better survival time in the treatment of advanced cancer and adverse reactions can be tolerated (Juxiang et al., 2015; Teng et al., 2018). Other reasons maybe they were included early in the list of national essential medicines, and widely used in the treatment of some high incidence and mortality cancers, such as lung cancer, gastric cancer, colon cancer in China (Yahong, 2019).
Price Comparison
As presented in Figure 3, most of the LPGs for anticancer could be acquired with acceptable price. Meanwhile, for OBs, the MPR value of Cytarabine, Oxaliplatin and Paclitaxel were much higher than the international reference price from MSH. Compared with LPGs, the relatively retail prices for OBs were much higher. This may be explained by the large patient’s rigid demand for the above three categories of medicines. In addition, the particularity of pharmaceutical production technical and core-patient barriers made it difficult for many domestic generic drugs to reach the ideal level and curative effect of the originator brand drugs (Cameron et al., 2009).
The government has been very concerned about the field of medicine prices. In recent years, it has also issued relevant policies to curb the disordered competition in pharmaceutical market. Launching the new direction of “purchasing with quantity, linking quantity with price and combining bidding and purchasing” has pushed the price of national essential drugs back to a reasonable level (Mao et al., 2019; Dong et al., 2020). Especially, after the conformity evaluation, generic drugs gradually occupy the share of originator brand drugs and expand the OBs’ substitution in favour of lowering public health expenditure in hospitals (Faruqui et al., 2019). Diversified and fair competitions between OBs and LPGs may bring more preferential benefits to patients.
Affordability
For the patients from low-income families in Hubei Province, they are still unable to afford course of treatment. Economic burden of disease becomes the major barrier that affects their access to effective targeted anticancer medicines (Mengyuan et al., 2017). In this study, the measurement affordability based on the total cost of treatment and the estimation of household income. The top five medicines with poor affordability were: Irinotecan, Oxaliplatin, Bicalutamide and Mycophenolate Mofetil, Methylprednisolone, which were more than 6 times of the 20% minimal monthly household income. The heavy payment burden may be caused by different dosages of 30 days treatment course and the unit price of each medicine. Meanwhile, in Mexico, most cancer medicines are also unaffordable for patients, the median affordability of patented medicines was 30.17 days’ wages needed to buy 1 day of one medicine’s supply (Moye-Holz et al., 2020). Hence, our government should establish special funds to support low-income household, and improve the efficiency of national medical insurance (Sarwar et al., 2018). Potential strategies worth consideration include: simplifing the approval process of new drugs at home and abroad, improving their access to the market, reducing the innovation cost, and attracking more high-quality anticancer generic drugs to enter the market (Eden et al., 2019). Importantly, in terms of the bidding and procurement process, National Health-care Security Administration negotiates with pharmaceutical manufacturers for reducing the OBs price and ensuring that the patients can afford the essential anticancer medicines (Jiao et al., 2018).
Limitations
In this survey, private hospitals and pharmacies were not included in the survey because only few designated pharmacies were licensed to operate special drugs (such as anti-cancer drugs) in China. Hence, the use of target anticancer drugs in designated pharmacies is of particular concern in subsequent studies. Second, during data collection, some “out-of-stock” medicines were not included in the calculation. Thus, the findings may not be generalizable to the whole availability of anticancer medicines. Lastly, for the convenience in comparing the affordability indicators, but lack of accounting for detailed cancer treatment protocols, all medicines charges were calculated according to the course of 30 days. In fact, the patient’s cancer type and risk stratum are different, which could lead to some biases in the accuracy of affordability.
Conclusion
Compared with secondary hospitals, it is obvious that the availability of essential anticancer medicines was found to be much higher in tertiary hospitals. Overall, LPGs was prior to OBs in terms of availability. “Drug addition cost” is a policy adopted by the government to compensate hospital income in a specific period of time. However, with the implementation of the “Zero Mark-up of Drugs” policy from 2009, for getting rid of compensation effect of drug income on public hospitals, the price of anticancer medicines returned to a reasonable level (Mao et al., 2019), apart from some special Originator Brand medicines’ price were still much higher than the international reference price. This study also identified several types of drugs that patients could hardly afford during the treatment. Policymakers should pay more attention to the possibility of poverty caused by expenditure on major cancer diseases. More actions should be adopted to regulate and restrict the pharmaceutical industry, drug circulation, patients and doctors, and improve the availability of essential anticancer medicines in Hubei Province.
