Investigating the intention to receive the COVID-19 vaccination in Macao: implications for vaccination strategies.

BACKGROUND: Understanding the intention of receiving COVID-19 vaccines is important to inform effective vaccination strategies. This study aimed to investigate such intention, identify the key influencing factors, and determine the most important intention predictors using a theoretically principled model. METHODS: An online, cross-sectional survey method was implemented in Macao in May 2021. People aged 18 years or above and residing in Macao for 12 months prior to the study were recruited through social media. Intention to receive COVID-19 vaccines and the main constructs of the protection motivation theory and the health belief model were the main measures encompassing threat appraisal, intrapersonal characteristics, cues to action, coping appraisal, past experiences and information seeking behavior. Descriptive statistics, Pearson correlation and multiple linear regression were used for data analysis. RESULTS: A total of 552 valid responses were received. Among the respondents, 79.5% aged between 25 and 54 years old, 59.4% were female, and 88% had a bachelor degree or above; 62.3% of the respondents indicated their intention to receive COVID-19 vaccination while 19.2% were hesitant and 18.5% did not have any intention. While 67.0% believed COVID-19 infection was life-threatening, only 19.0% thought they were at risk of getting infected. Control variables such as age, gender, education level, and having travel plans were significantly correlated with intention. Significant associations between intention with perceived severity, perceived susceptibility, maladaptive response reward, self-efficacy, response-efficacy, response cost, social attitude, social norm, past experience and information seeking behavior were identified (P < 0.05). The most important positive predictors of intention were "being able to make arrangement to receive the vaccine" (ß = 0.333, P < 0.001), "a sense of social responsibility" (ß = 0.326, P < 0.001), and "time off from work after vaccination" (ß = 0.169, P < 0.001), whereas "concerns over vaccine safety" (ß = - 0.124, P < 0.001) and "relying on online resources for vaccine information" (ß = - 0.065, P < 0.05) were negative predictors. Perceived severity in terms of COVID-19 being a life threatening illness was not a predictor of intention. CONCLUSION: This study reaffirmed that intention to receive COVID-19 vaccination is an ongoing concern in the combat of the pandemic. Multi-component strategies to enhance health literacy that supports well-informed decision-making, increase vaccination convenience, promote social responsibility, and provide time-off incentives are among the key considerations in designing and improve vaccination campaigns in Macao.

Quality Appraisal of the Pharmacoeconomic Research Literature about Antivirals: A Comparison between Chinese Medicine and Non-Chinese Medicine.

INTRODUCTION: Antiviral activity is a main function of many types of traditional Chinese medicine (TCM), and they may contribute more in the process of certain viral epidemics. Therefore, based on the effectiveness and economy of TCM, we aimed to determine the situation of health economic studies about antivirals, especially the difference between TCM and non-TCM. METHODS: A literature search of three databases was conducted with a time range of January 2000-December 2020, and terms related to health economics and TCM were used as key terms. QHES and CHEERS were used as quality assessment tools. RESULTS: 203 papers were included in our research. After evaluation using QHES and CHEERS, antiviral TCM obtained an overall score of 41.37 ± 4.46/99 in QHES, compared with 48.89 ± 7.25/99 (18.18% higher than TCM) of antiviral non-TCM. CONCLUSION: With a statistically significant difference, the overall quality of pharmacoeconomic research about antiviral non-Chinese medicine is better than that about antiviral Chinese medicine, which may have resulted from researchers' capacities or the absence of a more suitable standard for pharmacoeconomic research. It tells that the quality of pharmacoeconomic studies about TCM still warrants improvement.

Treatment efficacy analysis of traditional Chinese medicine for novel coronavirus pneumonia (COVID-19): an empirical study from Wuhan, Hubei Province, China.

BACKGROUND: A novel coronavirus was identified in December, 2019 in Wuhan, China, and traditional Chinese medicine (TCM) played an active role in combating the novel coronavirus pneumonia (NCP) caused by this fast-spreading virus COVID-19. Thus, we aimed to explore TCM characteristics of clinical efficacy to NCP, as well as to optimize Qingfei Paidu decoction (QFPDD) and the recommended formulas to NCP by National Health Commission (NHC). METHODS: Chinese medical sciences theory and clinical application of TCM were analyzed. A total of 54 NCP patients were observed in a hospital from Wuhan, whose clinical characteristics and utilization of Chinese Medicines (CMs) were described. Paired t test was used to measure the change of patients' hemogram during hospitalization period, indicating the effect of CMs. Multiple linear regression analysis was applied to explore the factors affecting the length of hospital stay. Network pharmacology analysis was applied to figure out the performance of NHC-recommended formulas of five disease stages at levels of compounds, targets and pathways. RESULT: The average length of hospital stay was 8.96 days. Patients over 45 stayed 9.79 days in hospital in average, longer than 7.64 days of patients under 45. Comparing the hemograms between admission and discharge of hospital, the number of leukocytes, neutrophil, lymphocyte and platelet increased, while the numbers of erythrocytes, hemoglobin concentration and hematocrit decreased. According to the standard coefficients of regression, the factor affecting the length of stay for the most was CMs in category of invigorating spleen and removing dampness (ISRD), followed by administrating CMs, male, and cough. Thirty-two CMs were screened after deleting duplication from QFPDD and NHC-recommended formulas. Compound quercetin, luteolin, kaempferol, acacetin etc., were all involved in the treatment of various disease stages on the compound level both in generality and individuality. CONCLUSION: TCM has a systemic theoretical understanding on the pathological evolution and a positive clinical efficacy on NCP. The CMs of ISRD improved patients' recovery, suggesting the importance of regulating intestinal function and keeping microenvironmental balance in TCM treatment of NCP. The active compounds from QFPDD and NHC-recommended formulas contribute to recovery of varied disease progresses during TCM treating NCP.
