OBJECTIVE: This study investigated the association between household chemical use and respiratory disease (RD) in older Chinese adults. METHODS: The data were from the 2018 China Longitudinal Health and Longevity Survey (CLHLS) database, which included 12,866 participants aged ≥ 65 years. The prevalence of RD was based on self-reported medical history, and patients were divided into diseased and non-diseased groups. The frequency of household chemical usage was divided into four categories, and a total score for eight household chemical usage categories was constructed. Binary logistic regression was used to determine the relationship between the frequency of household chemical use and RD, and a restricted cubic spline was used to determine the dose-response association. RESULT: After adjusting for all covariates, regular use of repellents [odds ratios ( OR) = 1.28, 95% CI 1.06-1.55] and oil removers ( OR = 1.28, 95% CI 1.03-1.58) were associated with RD. There was a dose-response association between the total score of household chemicals usage and RD risk ( P non-linearity > 0.05, P for trend < 0.01). Using patients with the total score below 9 as a reference, the OR for patients with the total score ranging from 25 to 32 is 2.33 (95% CI 1.25-4.09). CONCLUSION Regular use of repellents and oil removers increased the risk of RD, and the dose-dependent relationship was also observed.

Objective:To understand the situation of drug expense dishonour to the patients participated in health insurance new rural cooperative medical system ( NCMS) in our hospital, analyze the dishonour reasons and find countermeasures. Methods:The da-ta of drug expense dishonour to the patients participated in health insurance NCMS were collected in our hospital during October 2014 and October 2015, the reasons for the dishonour were analyzed, and countermeasures were proposed in order to reduce the dishonour under the policy of health insurance NCMS. Results:The most common reason of drug expense dishonour was the violation of restricted medication rules in the policy followed by the irrational use of Chinese medicines and antimicrobial drugs. Hospital should look for countermeasures according to the reasons for the dishonour in order to promote the implementation of the new rural cooperative medical policy and strengthen the rational and regular drug use under the policy of health insurance NCMS. Conclusion: The most important reason for drug expense dishonour was the incompletely implementation of the policy of health insurance NCMS, and the violation of drug use exists in our hospital. Pharmacy department should supervise drug use, focus on promoting the policy of health insurance NC-MS, implement forward position, participate in medication development and promote rational drug use.
