How employees perceive corruption risk


Transparency International (TI) defines corruption as “the abuse of entrusted power for private gain”.1 In China, the definition of corruption encompasses almost any form of “misconduct”.2 In addition to bribes, there are other corrupt manifestations related to public hospital staff, such as the theft of supplies and equipment, overbilling, unfair hiring practises,3 the embezzlement of research funds,4 absenteeism, informal payments, and dual practise.5–7 Corruption includes a series of extensive practices ranging from unethical behavior, and administrative misconduct to direct criminal offenses.8,9 To reduce corruption, the risks of corruption need to be identified and controlled as early as possible. As public hospital employees are potential subjects of corruption, the identification and perception of corruption risks by employees also require attention.

It is critical and necessary to assess the risk of corruption in public hospitals. The World Bank proposed that corruption risk assessment is the widespread evaluation of the level of governance.10 The worse regional governance is, the greater the risk of corruption.11 This evaluation also helps with transparency. Arostegui mentioned that citizens’ perceptions of corruption tend to change as the government undertakes reforms to control corruption.12 Additionally, corruption risk assessment is considered an anti-corruption intervention and an innovative method. The United Nations Development Fund (UNDP), the Council of Europe, the United States Agency for International Development (USAID) and others have assessed corruption risk in the health sector in Rwanda and Kosovo.7 According to Vian T, in the Middle East and North Africa (MENA), the UNDP is working on corruption risk mapping as part of long-term engagement based on prevention, risk management, and multistakeholder engagement.7 Mostafa Hunter developed the Conceptual Framework for Corruption Risk Assessment at the Sectoral Level as an approach to tackle corruption and enhance transparency and accountability in health care in Arab countries.13 However, previous studies have mainly focused on medical corruption at the regional or national levels, and anti-corruption tools are mostly based on large environments such as the health care industry, and the interactions between hospitals and enterprises.7,14 There is a lack of research on the corruption risk perceptions of public hospital staff.

To examine how employees perceive corruption risks in their hospital, we designed the “Questionnaire of Corruption Risk Perception Index in Public Hospitals” based on common types of corruption in public hospitals, and conducted a cross-sectional survey at West China Hospital (WCH) of Sichuan University. WCH is a large general public hospital and is one of 44 hospitals managed by the National Health Commission of the People’s Republic of China (PRC). It has 4300 beds and 7910 staff. With its functions of medicine, teaching, research and administration, WCH has a profound social influence in China, especially in the western region. Accordingly, due to the diversity and complexity of the work, employees (especially leaders at all levels at WCH) are exposed to a certain degree of corruption risk. The leadership structure in this hospital includes heads of the hospital, heads of administrative departments/clinical departments/laboratories (hereafter “departments”), deputy heads of departments, area leaders of departments, and leaders of professional teams (explanations are provided in Supplementary File 1). Generally, heads of the hospital, and heads and deputy heads of departments are referred to as the hospital’s core leaders; area leaders and professional team leaders are referred to as ordinary leaders. Understanding the corruption risk perception the hospital’s employees—especially leaders— can, to a certain extent, reflect awareness of corruption risks within the hospital among employees of Chinese public hospitals and provide a basis for further anti-corruption efforts.

Materials and Methods

Survey Instrument

Common individual corrupt practices are the focus of corruption research and intervention.15 To understand employees’ perceptions of corruption risks in public hospitals and to compare differences among employees with different characteristics, we developed a questionnaire based on information from five aspects: (1) manifestations of corruption (especially those in high-risk areas);16 (2) common corruption cases reported in the news; (3) criminal judgements made in China; (4) relevant research papers; and (5) key points of anti-corruption management in Chinese health care. TI defines corruption risk as the potential probability that corruption may occur and the costs associated with it; an increase in corruption risk implies a greater probability of corruption or a higher potential cost, or both.17 Referring to Mostafa Hunter’s work on the development of a risk heatmap for the health care sector in Arab countries,13 we used two dimensions to evaluate corruption risk: (1) the likelihood of corruption occurring; and (2) the impact of corruption when it does occur. The participants had to evaluate the likelihood and impact of each risk, which were divided into five levels represented by 5, 4, 3, 2, and 1, representing highly possible, easy, possible, unlikely, extremely rare and very serious, relatively serious, generally serious, not too serious, and no impact, respectively.18 Corruption risk can be expressed as a factor of the likelihood (L) multiplied by the impact (I), thus providing a ranking score.16 We defined the result of multiplying L by I as the Corruption Risk Perception Index (CRPI) score. According to previous research, we divided the CRPI scores into five levels: negligible, minor, moderate, serious, and critical (the levels and connotations of CRPI are displayed in Table 1).16 Six participants with various job positions (ie, head of the hospital, head of a department, nurse, doctor, officer) and education levels (ie, college to Ph.D) were invited to comment on the questionnaire and classification criteria, which we then modified. Afterward, using convenience sampling, we recruited 12 participants in a pilot study to evaluate feasibility and to obtain further comments on the questionnaire and classification criteria. We asked the 12 participants to assess whether the questionnaire was well laid out, whether the questions were clearly stated and easy to answer, and whether the classification criteria were reasonable (details are outlined in Supplementary File 2).

Table 1 The Levels and Connotations of the Corruption Risk Perception Index (CRPI)

The final version of the questionnaire is titled the “Questionnaire of Corruption Risk Perception Index in Public Hospitals”. It consists of four parts: (1) sociodemographic characteristics, with 7 items including gender, age, years of work experience, unit type, professional title, occupation, and leadership; (2) an assessment of 15 corruption risks with which most hospital employees are familiar (Table 2); (3) potential personal causes of corruption with 3 items, including poor understanding of management regulations, fluke ideas, and inadequate supervision; and (4) the most desired learning content about anti-corruption efforts, including 3 items including rules about behavior, punishment regulations, and the revelation of corruption cases. In addition, we asked the participants to give suggestions for future.

Data Collection and Analysis

We submitted the present study to WCH for approval and received it. To understand the true level of employees’ perceptions about the risk of corruption, we used an online survey format to avoid the oppressive feeling that a face-to-face survey may bring to employees. We used the software “WJX.CN” (Wenjuanxing) for data collection. This software formed a link that included survey invitations, confidentiality principles, and electronic questionnaires. We sent the link to employees on the hospital’s corporate WeChat platform (the platform incorporates all employees of the hospital, and each employee can send messages directly to other employees who are on the same platform). After the employees filled out the questionnaire, we fed the information directly into Wenjuanxing. No one except the research team knew the results of the responses.

All employees at WCH—including medical, administrative, teaching and research employees, except for interns—were eligible for the study. We adopted convenience sampling to obtain as many samples as possible. As we did not form any hypotheses, we did not estimate the sample size. To develop the study’s effectiveness and accuracy, we asked no less than two-thirds of employees in each department (5273 employees in total) to participate. We conducted the online, cross-sectional survey from 17 to 30 April, 2020. Before the investigation, we introduced a clear background explanation and set up the informed consent option for selection. If people did not want to participate, they could quit directly. We strictly adhered to the guidelines on research involving the use of human subjects based on the Helsinki Declaration, and we received approval for the ethics of the study.

Statistical Analysis

We exported the data to Excel 2016 and used IBM SPSS Statistics for Windows, Version 25.0 (SPSS, Inc., Chicago, IL, USA) to examine the results. The data are described as the mean, median, and quartile. We used hierarchical cluster analysis (Ward’s method and squared Euclidean distance interval measurement) to cluster the dimensions. We employed the Mann–Whitney U rank-sum test and the Kruskal–Wallis H rank-sum test to analyse the distribution of the CRPI among people with different characteristics. After we graded the CRPI, we used ordered multinomial logistic regression for multifactor analysis.


CRPI Ratings and Dimensions

Among all staff, a total of 5552 employees agreed to participate, of which 5525 responses were valid. The response rate was 69.85%; the characteristics of the respondents are reported in Table 3. Cronbach’s α of the questionnaire was 0.836. All participants evaluated that the average likelihood score of corruption risk in the hospital was 1.71, the impact score was 4.45, and the average CRPI was 7.57. Among all 15 risks, unreasonable personnel changes (CRPI=8.24), no collective discussions about important issues (CRPI=7.95), and violating individual moral character (CRPI=7.85) were the top three which participants rated the highest, while illegal procurement (CRPI=7.38), violating teaching ethics (CRPI=7.12) and violating medical ethics (CRPI=6.93) were rated the lowest (Table 3).

Table 3 Ranking of CRPI Scores for 15 Types of Corruption Risk

The results of cluster analysis indicate that the corruption risks of WCH were mainly concentrated in four major areas: (1) internal management (collective discussions, employing and retaining people, obeying decisions); (2) treatment regulation (rational drug use, rational inspection, and the rational use of consumables); (3) professional conduct (social morality, life morality, medical ethics, teachers’ morality, and academic ethics); and (4) external cooperation (accepting social donations for academic exchanges or academic conferences, bidding and cooperation among medical associations) (Figure 1).

The CRPI Distribution Difference

The CRPI distribution of employees with different genders, ages, years of work experience, professional titles, and occupations was significantly different, while there was no obvious difference between that of different unit types (H=0.618, P=0.734). Among all participants, the CRPI of males was higher than that of females (U=2794928.500, P=0.000). The distribution of the CRPI in different age groups (H=87.637, P=0.000) was different, and the CRPI of workers over age 40 was significantly higher than that of workers under 40. The distribution of the CRPI in groups with different years of work experience (H=87.637, P=0.000) was different, and the CRPI of those with more than 20 years of work experience was significantly higher than that of people with less than 20 years of experience. The professional title groups (H=178.635, P=0.000) also had significantly different CRPIs. There were significant differences in the CRPI distribution among workers of each occupation (H=136.925, P=0.000); doctors scored highest (M=8.000), while nurses scored lowest (M=6.89) (Supplementary File 3).

Being a leader was also one of the influencing factors of CRPI. Leaders had a greater CRPI score than clerks (U=2012206.500, P=0.000). The CRPI of leaders with ≥2 titles was higher than that of leaders with 1 title (U=38588.000, P=0.004). Length of leadership also led to a different distribution of a leader’s CRPI (H=9.061, P=0.028). The distribution of the CRPI in different position groups varied (H=77.089, P=0.000), and the CRPI of core leaders (including hospital heads, as well as heads and deputy heads of departments) was significantly higher than that of ordinary leaders (including area leaders of departments and leaders of a professional team). Hospital heads had the highest CRPI score (M=13.1650), which was much higher than that of the other groups (Supplementary Files 3 and 4).

The results of ordered multinomial logistic regression revealed that for all participants, being a leader was the key factor. The OR value of the CRPI of leaders was 0.768 times that of ordinary employees (95% CI: 0.623–0.945, χ2=6.189, P=0.013) (Table 4). For leaders, the position grade was the main point. The OR value of the CRPI of hospital heads was 28.552 times that of professional group leaders (95% CI:4.222–193.095, χ2=11.812, P=0.001), and the OR value of the CRPI of deputy heads was 2.217 times that of professional group leaders (95% CI: 1.046–4.699, χ2=4.320, P=0.038) (Table 5).

The Causes of Corruption and Suggestions for the Future

The 5525 participants also evaluated the causes of corruption. A total of 76.34% (4218/5525) suggested that the main cause was fluke ideas, reflected in the employee’s belief that his/her corrupt behavior will not be discovered, or even if discovered, will not be punished. A total of 53.94% (2980/5525) attributed the cause to a poor understanding of management regulations, while 37.85% (2091/5525) thought it was related to inadequate supervision. Regarding the most desired learning content about anti-corruption efforts, 84.71% (4680/5525) proposed “the revelation of corruption cases”, followed by “rules about behavior” and “punishment regulations”, which accounted for 78.55% (4340/5525) and 74.30% (4105/5525), respectively. A total of 317 participants put forward suggestions for future anti-corruption efforts, among which 66.30% (210/317) proposed that “education on corruption risks should be continuously strengthened, including the education of risk points, to improve our anti-corruption ability”, and 33.70% thought attention should be paid to “transparency”, “strengthening supervision and inspection” and “assistance in sorting out risk points”.


According to the results of cluster analysis and the ranking of items, the CRPI scores of internal management-related items ranked higher. The ranking of the three items was as follows: personnel recruitment ranked highest, collective decision-making ranked second, and decision-making execution ranked fourth. For external cooperation, the order of the three items was as follows: social donations for academic conferences ranked sixth, social donations for academic exchanges ranked eighth, and academic cooperation ranked ninth. This prompted us to conclude that compared with treatment regulations and professional conduct, internal management and external cooperation have a greater risk of corruption. The results are inconsistent with findings on corruption, such as “red envelopes” and “kickbacks”, which patients think are risky. This shows that hospital staff’s attention to the risk of corruption is different from that of patients, and the outcome is similar to that of Maxwell.19 Employees pay more attention to the influence on the cultivation of their abilities and job security. This indicates that hospital staff may be both implementers and victims of corruption, and corruption will also infringe on the interests of hospital staff.20 The result of corruption risk assessment reflects a series of institutional loopholes in the hospital management system or process that may be beneficial or conducive to corruption,16 and which can help the hospital to improve its management. Therefore, based on our findings, from the perspective of democratic management, WCH needs to pay attention to the construction and dynamic improvement of management regulations (especially those for internal management and external cooperation) to ensure that they have effective policies and procedures. In addition, the transparency of decision-making and implementation should be increased to reduce and control the source of corruption risk from inside the hospital.7

The results of the leadership and corruption risk assessment imply that leaders’ awareness of corruption risk is higher than that of ordinary employees. Among all leaders at WCH, the leaders with higher positions had higher CRPI scores than those with lower positions. Leaders who held multiple positions at the same time had higher CRPI scores than those who held a single position. Leaders who had been in their positions for longer had higher CRPI scores than those who held shorter positions. The four characteristics were all related to the use and supervision of discretion. The occurrence of corruption in the health sector is highly professional with job responsibilities and related to discretion.21,22 Compared with ordinary employees, leaders have greater public power. For example, pharmaceutical department heads had autonomous power in making decisions on medicine procurement and were able to influence the prescription of particular medicines in their hospitals.23 In addition, the higher the position, the more positions and the longer the tenure, the greater the discretion that leaders can control, and the greater the corresponding risk of corruption, which were similar to the findings of Nguyen.23 Therefore, it is necessary to restrict the exercise of the discretion of leaders at all levels in hospitals. We argue that we can strengthen this constraint from four angles. First, it is necessary to clarify the responsibilities and scope of each leader and to establish a list. Second, job responsibilities should be announced and staff should accept supervision. Third, there should be a separation of duties.19 In the decision-making and implementation process of major issues, according to the attributes and needs of events, key nodes should be divided according to workflow to ensure that different nodes are under the responsibility of different responsible personnel; each post forms mutual restrictions. Fourth, the rotation of key staff can be adopted to prevent excessive concentration of power.19 In addition, imperfect supervision mechanisms are considered important reasons for corruption.6,24–26 Zhang mentioned two reasons for the failure of supervision: the lack of incentives for supervision itself; and the fact that regulators themselves are in the chain of supervision failure.27 Because there is a multilevel leadership system in public hospitals, it is necessary to ensure the supervision of leaders at each level. Our results show that the CRPI varied significantly among those with different levels of leadership positions at WCH. The CRPI of core leaders was statistically higher than that of ordinary leaders (P<0.05), suggesting that the effect of the supervisory chain is not ideal. Hence, we think that in the internal supervision of the hospital leadership system, leaders should be both supervised and also supervisors. When discussing the anti-corruption responsibility system, the supervision function should be one of their duties. Guo Yong asserted that supervision influences the effectiveness of the anti-corruption system to a large extent.28 The “grid” supervision method can be adopted. In a vertical chain, superior leaders should supervise the subordinate leaders they manage and pass on the supervision pressure. Horizontally, adequate employee supervision should be adopted.16

Most employees think that the main personal cause of corruption is fluke ideas, which belong to the rationalization of corruption at the individual level. Vian T suggested that rationalization is one of the driving factors of corruption in the health care field.6 Fluke ideas manifest in the self-belief that corruption will not be discovered,29 and are largely due to the estimation of corruption costs by individuals in hospitals.30 To reduce fluke ideas, employees need to be aware of the increased cost of corruption. Thus, anti-corruption and integrity education should be continuously strengthened. In 2020, an editorial published in Lancet raised three questions about the governance of corruption in the health sector: (1) What is driving a particular form of corruption? (2) Who holds the power? (3) Who can make a difference?31 The risk of corruption should be recognized and managed based on power. As such, WCH needs to carry out education from the perspectives of power awareness and corruption costs. First, all employees should know that they have discretion and realize that they may face the choice of whether to engage in corrupt behavior. Employees should be vigilant in consciousness. Second, combined with the construction and improvement of hospital management regulations, employees should know these strict regulations and be aware of the increased cost of corruption and the inevitability and consequences of being discovered. Therefore, employees might choose not to be corrupt. In terms of educational methods, in addition to formal and informal education,32 it is very important to build a clean, honest culture in hospitals so that staff can be rooted in organizational values such as honesty and good management and promote integrity.19


Medical corruption leads to serious economic losses,33,34 distorts the distribution of health investment via its impact on people’s fair access to health resources,35 and has a huge effect on personal health, especially that of vulnerable groups.36 Medical corruption also undermines the progress of achieving the goal of universal health coverage (UHC) and affects the realization of sustainable development goals (SDGs).37 Hence, the fight against medical corruption has always been an important task for all stakeholders, including all staff members of medical institutions, regardless of whether they are leaders, specialists, or ordinary employees.

Due to the great harm of corruption in public hospitals, the assessment, control, and prevention of corruption have drawn attention.38 Understanding public hospital staff’s perceptions of corruption will help to identify areas where reforms are needed and provide a basis for good governance in that hospital. Our results indicate that among WCH employees, the corruption risks of internal management and external cooperation were greater than those of treatment regulations and professional conduct. People with different social characteristics had different perceptions of corruption. The corruption risk of leaders was higher than that of ordinary employees. The main personal reason for employees’ corruption behavior was fluke ideas. The findings imply the emphasis and direction of hospital management. First, WCH needs to pay attention to the construction and dynamic improvement of the hospital’s internal management regulations and external cooperation management regulations, and increase the transparency of decision-making and implementation. Second, it is necessary to restrict the discretion of leaders at all levels and to strengthen supervision. In addition, WCH needs to carry out education from the perspectives of power awareness and corruption costs, and to strive to build a clean, honest culture. The specific development mode and effectiveness of these measures should be examined in future research.

There are also some limitations of this study. We collected CRPI data in only one hospital and were unable to reveal the perceptions of hospital staff toward corruption on a large scale; the sample size needs to be increased. In the questionnaire, we covered 15 kinds of corruption risks that are mentioned most frequently in the literature, news, and criminal judgements, easily occur in public hospitals, and could be involved in and understood by most employees in hospitals. However, we did not include some corruption risks in which the majority of hospital staff may be seldom involved, such as hospitals’ infrastructure projects and gene detection. Therefore, follow-up studies in specific groups should be considered. In addition, this was a cross-sectional study, so we could not uncover the effectiveness of specific anti-corruption measures.
