Objective To explore the relationship between hearing loss and cognitive function in the elderly population through propensity score matching method.Methods We analyzed the data of 7605 participants aged 60 and above who were included in the 2018 China Health and Retirement Longitudinal Study(CHARLS).The non-substitutable 1∶1 nearest neighbor matching method without caliper value was used for propensity score matching and G-computation was used to estimate the average treatment effect(ATE)of hearing loss on all dimensions of cognitive function.Results Before matching,there were 3626(47.68%)women,with 1409(18.53%)of whom suffering from hearing loss and 3031(39.86%)of whom suffering from cognitive impairment.After matching,1409 subjects were included in the hearing loss group and 1409,in the normal hearing group,with both groups sharing similar distribution of basic demographic characteristics.The results for the average treatment effect of the population indicated that the cognitive function scores of the hearing loss group were lower than those of the normal hearing group,with the overall cognitive function being 0.593 points lower(95%confidence intervel[CI]:-0.916--0.257,P<0.001),orientation being 0.183 points lower(95%CI:-0.302--0.055,P=0.004),immediate memory being 0.150 points lower(95%CI:-0.218--0.085,P<0.001),and language skills being 0.178 points lower(95%CI:-0.303--0.058,P=0.006).The prevalence of cognitive impairment of the hearing loss group was 4.2%higher than that of the normal hearing group(95%CI:0.007-0.077,P=0.020).Conclusion Hearing loss adversely affects the orientation,memory,and language skills of the elderly population and forms a potential risk factor for cognitive impairment in the elderly population.

Objective:To analyze the characteristics of demoralization in patients with primary liver cancer undergoing transcatheter arterial chemoembolization (TACE) and the differences of death anxiety among these types using latent profile analysis.Methods:Based on the cross-sectional design, 216 patients with primary liver cancer undergoing TACE of the First Affiliated Hospital of Zhengzhou University were selected by convenient sampling method from July 2018 to May 2021, and were investigated by using the general data questionnaire, Demoralization Scale and Templer′s Death Anxiety Scale.Results:A total of 139 cases (64.4%) with high demoralization and 120 cases (55.6%) with high death anxiety were detected. The patients were divided into four subtypes: 67 cases(31.0%) in the emotional distress group, 52 cases(24.1%) in the high risk group, 72 cases (33.3%) in the sense loss group, and 25 cases (11.6%) in the low risk group. Tumor stage and working status were the main factors affecting the characteristic classification of demoralization ( β=2.615, 2.085, both P<0.05). There were significant differences in death anxiety among different subtypes of patients ( H=77.00, P<0.01). Conclusions:The level of death anxiety is higher in patients with primary liver cancer after TACE surgery, and there are differences in different subtypes of patients with demoralization. Medical staff should formulate targeted intervention measures for different subtypes of patients to reduce their symptoms of demoralization and death anxiety.

Different from the traditional health technology assessment(HTA), hospital-based health technology assessment(HB-HTA) is mainly based on the perspective of the hospital to carry out economic analysis, commonly used cost-effectiveness analysis combined with budget impact analysis methods. It pays attention to the current medical costs and effects, and supports the hospital′s internal health technology access, purchase pricing, elimination and other decisions. In the context of deepening the reform of medical insurance payment mode in China, the hospital internal medicine decision-making based on HB-HTA is particularly important. Based on the economic characteristics of health technology, the authors analyzed the differences between HB-HTA and traditional HTA in carrying out economic evaluation, introduced the steps, contents, indicators and methods of HB-HTA economic evaluation, and put forward relevant strategic suggestions.
