The chemical constituents of fistular onion stalk obtained by supercritical CO(2) extraction were separated and purified by silica gel and sephadex LH-20 gel column chromatography and the preparative TLC method and four flavonoids were obtained. On the basis of the spectral data, they were structurally identified as (+)-catechin, (-)-epicatechin, astragalin, and 3-O-beta-D(2-O-beta-D-glucopyranosyl)-glucopyranosides of kaempferol.

Objective:To analyze the satisfaction of elderly outpatient experience, based on a satisfaction questionnaire survey of outpatients in public hospitals, for references to improve the medical experience of elderly patients.Methods:This study extracted the satisfaction survey questionnaires for outpatients in second level and above public hospitals nationwide from the National Health Commission′s satisfaction survey platform from 2019 to 2022. The questionnaire content included six dimensions: registration experience, doctor-patient communication, nurse-patient communication, environment and labeling, privacy protection, and medical staff response, as well as overall satisfaction. The satisfaction, relative satisfaction, and dissatisfaction rates of elderly outpatients were analyzed using standardized assignment of question options, etc; T-test was used for inter group comparison.Results:A total of 10.095 7 million outpatient satisfaction questionnaires were included in this study, including 0.576 3 million questionnaires for elderly outpatients. From 2019 to 2022, the overall satisfaction of outpatients had been increasing year by year, and the overall satisfaction scores of elderly patients were significantly higher than that of non-elderly patients( P<0.01). The satisfaction scores of elderly patients in the nurse communication dimension(86.55 to 91.03 points) and relative satisfaction(1.000) were the higher in each year, while the satisfaction scores in the environment and identification dimension(81.05 to 86.03 points) and relative satisfaction(0.935 to 0.955) were lower. In 2019 and 2022, elderly patients had higher dissatisfaction rates in the two dimensions of registration experience(2.26%, 1.91%) and doctor communication(0.80%, 0.53%). Conclusions:From 2019 to 2022, the overall satisfaction of elderly patients in secondary and above public hospitals in China was relatively higher with a steady increasing tendency. However, there was still room for further improvement in the environment and labeling, cultural construction, and registration experience for elderly patients.
