Objective:To analyze the policy tools designed for function orientation and development of China′s infectious disease hospitals, in order to provide references for formulating and optimizing the functional implementation and sustainable development policies of these hospitals.Methods:Consulting the website of Peking University Law and official websites on health, and using such keywords as " medical institutions, infectious diseases, hospitals for infectious diseases, public health emergencies, specialized hospitals", and searching the national policy texts on the functions and development of infectious disease hospitals issued from December 1991 to January 2023. By means of Rothwell and Zegveld′s policy tool classification method, Nvivo 11 Pro software was used to analyze the text content from the dimensions of demand-type, supply-type, and environmental-type policy tools.Results:A total of 41 policy texts were included and 204 codes were obtained through text analysis. Of all the tools, environmental and supply-oriented policy tools were used the most, being 104 (50.99%) and 95 (46.56%) respectively, while demand-oriented policy tools were used the least, only 5 (2.45%). Of all the environmental-oriented policy tools, " goal planning" was the most used, being 34 (16.67%), while " publicity and guidance" was less used, only 4 (1.96%). Among the supply-oriented policy tools, " clarifying the reporting and handling service functions of public health emergencies" was the most widely used, being 34 (16.67%), while " Informationization" and " infrastructure construction" was less used, being 8 (3.92%) and 6 (2.94%) respectively. Few of the demand-oriented policy tools were in use, as " government purchase" and " medical insurance support" were both 2 (0.98% each), and " social medical care" was only 1 (0.49%).Conclusions:The distribution of three types of policy tools for function and development of infectious disease hospitals is unbalanced, the use of environmental and supply-oriented policy tools is excessive and internal structure is unbalanced. The proportion of environmental-oriented policy tools needs to be adjusted, and the frequency of use of supporting tools such as relevant standards, norms, incentives, supervision and publicity should be increased. Supply-oriented policies need to be further optimized, especially in terms of personnel training, funding, information technology and infrastructure construction. Demand-oriented policy tools are seriously underused and need to be further developed.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.
