Background Since the outbreak of the respiratory infectious disease caused by the novel coronavirus in 2019, the COVID-19 epidemic has posed a serious threat to the life and safety of the public, and has also seriously affected the normal study and life of college students in China. Although a series of studies have been conducted on college students’ knowledge, attitudes and practices of COVID-19, the results vary widely. This study aimed to evaluate the pooled estimated level of knowledge, attitudes, and practices (KAP) about COVID-19 among college students in China. Methods We conducted a comprehensive search on Scopus, ProQuest, PubMed, EMbase, Web of Science, the Cochrane Library, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), VIP Database and Wanfang Database up to 13 February 2022. We then assessed the quality of included studies using a checklist developed by the Joanna Briggs Institute (JBI) for cross-sectional studies and analyzed using STATA.15 after two researchers independently extracted relevant data and entered them into Microsoft Excel. Funnel plots and Egger’s regression tests were used to check for publication bias, and sensitivity analysis was performed to assess the robustness of the results. A random-effects model was used for the meta-analysis, on the basis of which subgroup analyses were performed by time of investigation (study period) and by gender and major of the subjects. Result A total of 42 studies including 174,440 subjects were included in this review, and the quality of the included studies was mainly intermediate and advanced. The findings of the meta-analysis showed that the overall levels of Chinese college students’ knowledge, positive and negative attitudes, and practice of preventive measures towards COVID-19 were 74% (95%CI: 69%-79%), 84% (95%CI: 80%-88%), 31% (95%CI: 23%-38%) and 82% (95%CI: 77%-86%), respectively. The results of subgroup analysis showed that female and medical college students had higher levels of knowledge and practice on COVID-19. Conclusion The study findings showed that the overall KAP level of college students in China included in the study was relatively optimistic. Influenced by gender, major and time, there were differences in the KAP level of college students. In order to promote the effective prophylaxis and control of pandemic, we recommend implementing targeted measures to improve the awareness rate of COVID-19-related knowledge among this group and the implementation rate of COVID-19 preventive measures among male and non-medical college students.

Lack of knowledge about palliative care is one of the most common reasons for hindering the delivery of high-quality palliative care. Nurses play a major role in providing palliative care, and the degree of their mastery of this knowledge is crucial to whether they can effectively deliver the ideal palliative care. Therefore, it is necessary to understand the level of palliative care knowledge in this population. As of 8 November 8, 2022, we performed systematic searches in 10 databases. Meta-analysis of quantitative data that measuring the level of palliative care knowledge of nurses using the Palliative Care Quiz for Nursing (PCQN) was conducted using Stata software (version: V.15). A pooled mean score <10 indicated a low/insufficient knowledge level. The funnel plot and Egger’s regression test were used to detect publication bias, and finally, the robustness of the results was evaluated through sensitivity analysis. The pooled mean score for the level of nurses’ knowledge of palliative care was 9.68 (95% CI: 9.40 to 9.96). Among the three dimensions of the PCQN scale, the pooled mean score for the ‘“Philosophy and Principles of Palliative Care’” section was 1.73 (95% CI: 1.38 to 2.08); the ‘“Pain and Other Symptom Control’” section was 6.73 (95% CI: 6.41 to 7.05); and the ‘“Psychological, Spiritual and Social Care’” section was 1.21 (95% CI: 0.72 to 1.69). It can be seen that nurses’ mastery of palliative care knowledge is not sufficient. It is recommended that relevant departments formulate and promote the implementation of targeted measures to improve the knowledge level of this population.
