Acceptance and attitude towards the traditional chinese medicine among asymptomatic COVID-19 patients in Shanghai Fangcang hospital

Abstract

Objective

The Coronavirus Disease 2019 (COVID-19) has brought severe damage to global health and socioeconomics. In China, traditional Chinese medicine (TCM) is the most important complementary and alternative medicine (CAM) and it has shown a beneficial role in the prevention and treatment of COVID-19. However, it is unknown whether patients are willing to accept TCM treatment. The objective of our study is to investigate the acceptance, attitude, and independent predictors of TCM among asymptomatic COVID-19 patients admitted to Shanghai fangcang hospital during the outbreak of the COVID-19 pandemic in Shanghai in 2022.

Methods

A cross-sectional study was conducted on asymptomatic COVID-19 patients in the largest fangcang hospital in Shanghai, China, from April 22, 2022, to May 25, 2022. Based on the literature review of previous similar studies, a self-report questionnaire was developed to assess the patients’ attitude and acceptance of TCM, and a multivariate logistic regression analysis was conducted to determine the independent predictors of TCM acceptance.

Results

A total of 1,121 patients completed the survey, of whom 91.35% were willing to accept CAM treatment whereas 8.65% of participants showed no willingness. Multivariate logistic regression analysis revealed that the patients who have received two doses of COVID-19 vaccine (OR = 2.069, 95%CI: 1.029–4.162, P = 0.041 vs. not received), understood the culture of TCM (OR = 2.293, 95%CI: 1.029–4.162, P = 0.014 vs. not understood), thought the TCM treatment is safe (OR = 2.856, 95%CI: 1.334–6.112, P = 0.007 vs. not thought), thought the TCM treatment is effective (OR = 2.724, 95%CI: 1.249–5.940, P = 0.012 vs. not thought), and those who informed their attending physician if using TCM for treatment (OR = 3.455, 95%CI:1.867–6.392, P < 0.001 vs. not informed) were more likely to accept TCM treatment. However, patients who thought TCM might delay your treatment (OR = 0.256, 95%CI: 0.142–0.462, P < 0.001 not thought) was an independent predictor for unwillingness to accept TCM treatment.

Conclusion

This study preliminarily investigated the acceptance, attitude, and predictors of intention to receive TCM among asymptomatic COVID-19 patients. It is recommended to increase the publicity of TCM, clarify the impact of TCM and communicate with attending doctors that meet the healthcare needs of asymptomatic COVID-19 patients.

Background

At present, the Coronavirus Disease 2019 (COVID-19) is still spreading all over the world, which has brought a heavy burden to the global economic recovery and made the fragile healthcare system of some developing countries fall into a state of being on the verge of collapse. The daily number of confirmed cases presents a rising trajectory across the globe. As of January 27, 2023, the total number of confirmed cases had reached over 752 million with more than 6.80 million deaths worldwide [1].

Complementary and alternative medicine (CAM) is defined as a set of different medical and healthcare systems, practices, and products, which are generally not considered part of traditional medicine [2]. One survey carried out in Iran between April 20, 2020, and August 20, 2020, demonstrated that at least one type of CAM was used by 84% of the participants during the outbreak of the COVID-19 pandemic. In the majority of participants, CAM was adopted to prevent the infection of COVID-19 or reduce the anxiety caused by the COVID-19 pandemic [3]. An anonymous electronic survey was conducted in Ghana showed that 82.5% of the participants applied CAM during COVID-19 [4]. A meta-analysis showed that different CAM interventions such as acupuncture, traditional Chinese medicine (TCM), relaxation, and Gongfa significantly alleviated the psychological symptoms (depression, anxiety, stress, sleep quality, negative emotions, quality of life) and physical symptoms (inflammatory factors, physical activity, chest pain, and respiratory function) in COVID-19 patients [5].

As an important part of CAM in China, TCM has its characteristics in the prevention and treatment of acute infectious diseases [6, 7], which is one of the major therapies recommended in the guideline for prevention, control, diagnosis, and treatment of COVID-19 published by the National Health Commission of China [8]. A clinical study conducted at Wuhan fangcang hospitals found that early treatment with Huashibaidu granule for seven days alleviated the deterioration of symptoms in COVID-19 patients with moderate and mild symptoms [9]. Another study also showed that Lianhua Qingwen capsules could significantly shorten the median time of recovery and improve the improvement rate of chest CT imaging as well as the clinical cure rate. Moreover, the role of TCM in the prevention and control of COVID-19 has been recognized by the World Health Organization [10].

In the last week of February 2022, the Omicron BA 2.2 variant of COVID-19 caused a wave of infection in Shanghai, China [11]. Asymptomatic COVID-19 patients were sent to Fangcang hospitals by the community, which were upgraded to designated hospitals for the treatment of asymptomatic COVID-19 patients. To apply TCM to more asymptomatic COVID-19 patients, it is particularly important to understand their hesitation to take TCM. Up to now, no research data has been published regarding the willingness of asymptomatic COVID-19 patients to accept TCM. Thus, we conducted an online cross-sectional study to record the acceptance and attitude towards TCM by asymptomatic COVID-19 patients and analyzed the predictors influencing the patients’ acceptance of treatment with TCM.

Materials and Methods

Study design and participants

An online questionnaire survey was conducted among adult asymptomatic COVID-19 patients who were admitted to the largest fangcang hospital (Si Ye Cao Fangcang hospital) in Shanghai, China, from April 22, 2022, to May 25, 2022. This study employed the “Wenjuanxing” platform to distribute and retrieve electronic questionnaires, and export relevant data information. Patients with intellectual and cognitive impairment were excluded from the survey.

Ethical approval

The study was approved by the Ethics Committee of The First Affiliated Hospital of Naval Medical University, China (CHEC2022-056). All methods were carried out in accordance with the Declaration of Helsinki. Oral informed consent was obtained and all of the participants were briefed about the purpose of the study, research procedures, privacy of their identity and any other personal information, and their other relevant rights.

Questionnaires

A self-administered questionnaire was constructed in the Chinese language to evaluate the acceptance and attitude towards TCM. The questionnaire was developed based on the literature review of similar studies and was translated into the Chinese language before distribution to the patients [3, 4, 12,13,14,15,16,17,18,19,20,21,22].

The questionnaire mainly included four parts: (1) Basic information of participants included demographic characteristics (gender, age, body mass index, education level, average monthly income, residence, employment, current smoking status, and current drinking status) and clinical characteristics (comorbidities, vaccination status, and knowledge about culture of TCM). (2) Participants’ attitude toward TCM was determined through the following questions: do you think it takes a long time for TCM to exert efficacy, do you think the TCM treatment is safe, do you think the TCM treatment is effective, will you inform your attending physician if you accept TCM for treatment, and do you think TCM might delay your treatment. (3) Participants’ willingness to take TCM; first, participants were asked to respond to whether they are willing to accept TCM, and if the answer was “Yes”, they were further asked about the types of TCM they were willing to accept and the reasons for their willingness to accept TCM. If the patients were not willing to accept TCM, they were asked the reasons for their unwillingness to accept TCM. We conducted a pilot testing of the main question assessing the willingness to accept TCM among over 50 respondents and did not detect any problems.

Sample size estimation and data analysis

Based on a previous report [3], the proportion of TCM utilization was assumed as 84% in the calculation of sample size using the following formula:

$$n = Z_{1 - \alpha /2}^2P(1 - P)/{e^2}$$

Where n is the minimum number of required patients, Z2 indicates 1.962 for 95% confidence interval (CI), P presented the estimated utilization rate, and e indicated the required accuracy of 4%. The non-response rate was estimated as 5% and the minimum sample size was calculated as 339 patients.

Data analysis was performed using IBM SPSS Statistics for Windows (version 21.0). Participants’ responses to the questionnaire were treated as classified data, which were expressed by numbers and percentages. Univariate analysis was used to evaluate the relationship between independent variables (participants’ basic information and participants’ attitude towards TCM) and dependent variables (participants’ acceptance towards TCM). The variables with a value of P < 0.25 in univariate analysis were put into a multivariate logistic regression analysis to determine the Predictors affecting patients’ willingness to accept TCM. Odds ratio (OR) and 95%CI were adopted to describe these variables. P < 0.05 was considered statistically significant.

Results

Participants’ characteristics and willingness to accept TCM

A total of 1,185 asymptomatic patients were invited to participate in the survey. One patient submitted an incomplete questionnaire whereas the response was not received from 63 patients. Finally, responses from a total of 1,121 patients were included in the analysis. The overall effective questionnaire recovery rate was 96.60%.

In our study, 1024 participants expressed their willingness to receive TCM, the rate of TCM acceptance was 91.35%. Only 97 participants represented unwillingness to receive TCM, the rate of TCM hesitancy was 8.65% (Table 1).

Table 1 Demographic characteristics and clinical features of participants

The relationship of various characteristics with the acceptance of TCM is presented in Table 1. The willingness to accept TCM differed insignificantly (P > 0.05) between various demographic characteristics except for the monthly income. Having a monthly income of more than 3,000 yuan, the proportion of participants vaccinated with two doses of COVID-19 vaccines and understanding the culture of TCM were significantly higher for showing a willingness to accept TCM in comparison to those who showed unwillingness.

Participants’ attitude towards TCM

Table 2 shows significant statistical differences in attitude towards TCM between the TCM hesitancy and TCM acceptance groups (P < 0.001 for all the five related questions). In our study, nearly one-fifth of the respondents thought that TCM needed a longer time to take effect. Interestingly, most respondents believed that TCM treatment was safe (1013/1121, 90.37%) and effective (1019/1121, 90.90%), only 11.60% (130/1121) of the participants believed that TCM would delay their treatment.

Independent predictors of TCM acceptance

According to univariate analysis, 13 variables with P < 0.25 were obtained (Tables 1 and 2). Multivariate logistic regression analysis indicated that 6 variables influenced the willingness to accept TCM (P < 0.05) (Table 3). The participants who have received two doses of COVID-19 vaccine (OR = 2.069, 95%CI: 1.029–4.162, P = 0.041 vs. not received), understood the culture of TCM (OR = 2.293, 95%CI: 1.029–4.162, P = 0.014 vs. not understood), thought the TCM treatment is safe (OR = 2.856, 95%CI: 1.334–6.112, P = 0.007 vs. not thought), thought the TCM treatment is effective (OR = 2.724, 95%CI: 1.249–5.940, P = 0.012 vs. not thought), and those who informed their attending physician if using TCM for treatment (OR = 3.455, 95%CI:1.867–6.392, P < 0.001 vs. not informed) were more likely to accept TCM treatment. However, the participants who thought TCM might delay your treatment (OR = 0.256, 95%CI: 0.142–0.462, P < 0.001 not thought) was unwilling to accept TCM treatment.

The sources of information about TCM

The present study found that the most important source of TCM information for the participants was the media (494/1121, 44.07%), followed by families and friends (459/1121, 40.95%) and medical staff (427/1121, 38.09%) (Fig. 1).

Discussion

At present, the COVID-19 pandemic is still spreading all over the world, with constant mutation, which increases the difficulty of prevention and control. TCM has a long history in the prevention and treatment of acute infectious diseases and the experiences of TCM treatment have been recorded in the Shanghan Lun and Detailed Analysis of Epidemic Warm Diseases [9], which provided a new scheme for treating COVID-19 [23,24,25,26,27]. However, the willingness to accept TCM among asymptomatic COVID-19 patients was not reported in the literature.

The present study explored the acceptance of TCM and its independent predictors among asymptomatic COVID-19 patients and found that 91.35% of the patients were willing to accept TCM treatment, while 8.65% of the patients presented unwillingness to accept TCM. Demographic factors including gender, age, education level, income level, and residence were not significantly associated with TCM acceptance in the present study, which was different from the cross-sectional studies reported from other regions [28,29,30,31]. National Health Commission of the People’s Republic of China has repeatedly mentioned the promotion of TCM in the prevention and control of COVID-19, we put forward the following suggestions to accelerate the acceptance of TCM based on the results of this study.

Increasing the publicity of TCM is important to promote the acceptance of TCM

TCM is a significant part of Chinese cultural heritage, which ideas and practice methods contain the profound wisdom of Chinese philosophy [32]. The multivariate logistic regression analyses indicated that participants who understood the culture of TCM was one of predictors for TCM acceptance, but more than half of the participants lacked an understanding of the culture of TCM in our study. A cross-sectional study in Australia reported that only 26% of dental students knew about CAM [33]. In Hungary, 12.4% of the subjects showed a better understanding of CAM [34]. In Bangladesh, nearly 45% of pharmaceutical students believed that lack of knowledge was the main obstacle to the application of CAM [35]. Given that TCM theory is difficult for non-professionals to understand, a concise and comprehensive introduction of TCM is necessary.

Participants of the present study reported that the most important source of their TCM information was media (44.07%), followed by family members and friends (40.95%) and medical staff (38.09%). In India, the majority of dental practitioners (73.3%) reported that media (internet, newspapers, etc.) was their main source of knowledge about CAM [36]. One study in Silesia, Poland, demonstrated that 60.8% of patients obtained information about CAM from the internet and 38.6% acquired information from television. These results indicated that appropriate media publicity is conducive to guiding and enhancing the public’s receptivity to TCM [37]. This raises requirements for TCM practitioners in China.

Clarifying the impact of TCM is the premise of advocating TCM

According to the results of the present study, among the participants who were willing to accept TCM, 70.51% preferred Chinese herbal medicine, 62.79% chose Chinese patent medicine, and 34.96% favored massage treatment. A survey on patients with Parkinson disease in China illustrated that herbal medicine, rehabilitation exercise, and acupuncture were the most commonly used TCM therapies [38]. Compared to other TCM therapies, Chinese herbal medicine is the most popular treatment in China.

The safety and efficacy of the TCM is critical to controlling the COVID-19 and has caused widespread concern. Multivariate logistic regression analysis in the current study showed that safety and efficacy of the TCM were the independent predictors for willingness to accept TCM. These results were higher than data from others countries. A survey on diabetic patients in Jeddah Saudi Arabia showed that 54.2% patients believed CAM have no side effect. A study in Indonesia indicated that 68.31% of diabetic patients considered that CAM products were safe and 63.69% of diabetic patients considered that CAM products were effective.

However, considering TCM would delay the treatment was an important independent predictor for hesitation to accept TCM in this study. In fact, the clinical role of TCM in the management of COVID-19 has been verified by clinical trials in China [39, 40]. Therefore, considering the willingness of asymptomatic COVID-19 patients to accept TCM and the effectiveness and safety of the TCM, clarifying the impact of TCM is the premise of advocating TCM for the patients.

Active communication with attending doctors contribute to acceptance of TCM

Communication between doctors and patients plays an important part in healthcare activities [41], which can determine the patients’ self-management behavior and health outcomes [42]. Our study indicated that informing the attending doctor before receiving TCM treatment is an important predictors for willingness to accept TCM treatment. A study conducted in Palestine from April 2018 to March 2019 exhibited that 64.0% of pregnant women believed that doctors should provide patients with advice on commonly used CAM therapies [43]. In Saudi Arabia, 81.11% of the subjects intended to discuss the application of CAM with their doctors [44]. According to the outpatient service in Iran, among 155 patients who accepted CAM voluntarily, 50 patients (32.2%) reported that they had disclosed the usage of CAM to their doctors [45]. These results suggested that patients had a strong interest in receiving CAM with the advice of their physicians.

In the present study, when participants were asked the reason behind their willingness to accept TCM treatment, only 26.27% of the participants said that it was due to the recommendation by medical staff. When asked about their hesitation toward TCM treatment, 36.08% of participants replied that it had not been recommended by medical staff. Therefore, healthcare practitioners must have a certain understanding of CAM so that they can actively communicate with patients and recommend the most appropriate treatment according to the patients’ conditions. According to a survey in Germany, more than half of the patients expressed their interest in CAM consultation and more than 80% of patients expected their attending doctor to have a certain knowledge of CAM [46]. In India, 57.5% of dental practitioners reported that health professionals should be able to provide patients with advice on commonly used CAM methods [36].

Limitations

This study has several limitations. First of all, this study is a self-administered questionnaire-based cross-sectional study. Thus, the causality cannot be directly deduced and further longitudinal research is needed to verify the possible causal relationship. Secondly, the questionnaire was developed based on multiple questionnaires but it could not be verified in a large sample size due to time constraints. Thirdly, the sample had a low representation of the elderly (> 60 years old) owing to few admissions of participants of this age to the fangcang hospital. Fourthly, since our survey was just conducted in the largest fangcang hospital in Shanghai, it cannot fully represent the willingness of asymptomatic COVID-19-infected people in Shanghai and even in the world. Fifthly, as the world is urgently fighting against COVID-19, more outcomes of TCM treatment for COVID-19 will be published, which may affect the willingness of patients to accept TCM.

Conclusion

This study reported the attitude and willingness to accept TCM in asymptomatic COVID-19 patients and their predictors worldwide. In this survey, 91.35% of the participants were willing to accept CAM treatment, while 8.65% of the participants were not willing to accept CAM treatment. Receiving two dose of COVID-19 vaccine, understanding the culture of TCM, thinking TCM is safe and effective, and informing the attending doctor before using TCM were contributors to TCM acceptance, whereas the main contributors to TCM hesitancy was considering that TCM would delay the treatment. Thus, strengthening publicity through the media, especially the emerging network media such as WeChat, microblog, and Zhihu, to generalize the advantages of TCM to the public, inviting the recovering COVID-19 patients who were treated with TCM to give health lectures and broadcasting the clinical practice of TCM in the treatment of COVID-19 in asymptomatic COVID-19 patients, and recommending TCM and teaching some gongfa of TCM (tai chi, qi gong, wuqinxi, etc.) to benefit patients by attending doctors may expand the acceptance of TCM. Further observation will be carried out on this batch of patients to calculate the final prevalence rate of TCM and a long-term follow-up will be conducted to observe the effects of TCM on the quality of life of patients with COVID-19.
