  • Cost-effectiveness analysis of chemotherapy regiments in children with newly diagnosed Hodgkin lymphoma

    Objective To evaluate the cost-effectiveness of chemotherapy in children with newly diagnosed Hodgkin lymphoma at low-, intermediate-, and high-risk. Methods From the perspective of health system, a decision-tree model was designed for cost-effectiveness analysis. The chemotherapy regimens of low-risk group included OEPA (vincristine, etoposide, prednisone, doxorubicin), AV-PC (doxorubicin, vincristine, prednisone, cyclophosphamide), and ABVD (doxorubicin, bleomycin, vincristine, dacarbazine); intermediate-risk group included OEPA, ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide) and ABVD; high-risk group included OEPA, ABVE-PC, ABVD and BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). The effectiveness and cost parameters were derived from the event-free survival rate reported in the literature, the drug linked reference price in Sichuan province, and treatment price of medical institutions. Univariate and probabilistic sensitivity analysis were performed to explore the impact of uncertainty. Results In the low-risk group, compared with AV-PC, the incremental cost-effectiveness ratios (ICER) of OEPA and ABVD were 80 700 yuan and 108 799 yuan, respectively. In the intermediate-risk group, compared with OEPA, the ICER of ABVE-PC and ABVD were −17 737 yuan and −4 701 yuan respectively. In the high-risk group, compared with ABVE-PC, the ICER of OEPA, ABVD and BEACOPP were 149 262, 472 090 and 64 652 yuan, respectively. Univariate sensitivity analysis showed that in low-risk group, the most influential factors were cost of OEPA and cost of ABVD; in moderate-risk group were cost of ABVE-PC and cost of OEPA; in the high-risk group were cost of OEPA, cost of ABVD, and cost of BEACOPP, respectively. The results of probabilistic sensitivity analysis are basically consistent with those of the main analysis. Conclusion If China's per capita gross domestic product in 2023 (89 358 yuan) was used as the willingness-to-pay (WTP) threshold, OEPA in the low-risk group, OEPA in the intermediate-risk group and BEACOPP in the high-risk group are cost-effective.

  • Research on the sustainability of information collection APP in rural basic public health services based on mixed-method

    ObjectivePublic health information collection is critical in improving the capacity of basic public health services. Our study took the "Wei Jian E Tong" APP as an example to evaluate the willingness and influencing factors of rural public health service personnel to continue using such APPs.MethodsWe applied exploratory sequential design in mixed-method research and chose Renshou county in Sichuan province as the representative region. Firstly, we used the personal in-depth interview to initially explore the status quo, applicability, continued willingness to use APP and other issues. Secondly, we used unified theory of acceptance and use of technology (UTAUT) and expectation confirmation theory (ECT) to construct a hypothetical model of influencing factors of user satisfaction. We then designed a structured questionnaire covering 7 measurement dimensions to survey all users of the APP at the survey site. Finally, we used structural equation model to verify the research hypothesis.ResultsA total of 21 individuals were interviewed in this survey, including leaders of township health centers, public health doctors, and rural doctors. Qualitative results showed the major defects were insufficient funds and policy support in the promotion and application, additionally lack of software functionalities and system incompatibility. A total of 593 valid questionnaires were collected from the quantitative survey on the satisfaction of township doctors and village doctors. Structural equation model results showed that seven direct hypotheses were established, of which compatibility had the largest effect value user satisfaction with a total effect value of 0.617, followed by facilitating condition (r=0.211), performance expectancy (r=0.137), effort expectancy (r=0.091) and social influence (r=0.068).ConclusionsTo promote the application of information collection apps in primary public health services and improve user satisfaction, the focus should be on solving software incompatibility and create interconnection among all levels of medical systems. At the same time, it is necessary to solve funding problems as a whole, optimize software functions, improve the performance evaluation system, and improve software training and promotion.

    ObjectiveTo systematically review the safety of hand disinfectants. MethodsPubMed, EMbase, The Cochrane Library, INAHTA, WanFang Data, CNKI and VIP databases were electronically searched to collect studies on the safety of hand disinfectants from inception to February 1st, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies; then, a systematic review was conducted. ResultsA total of 50 studies were included. The reported adverse events were eye and nasal mucosal irritation, hand adverse events with skin itching, rash, erythema, edema and so on. A total of 29 brands such as 3M Avagard and 26 ingredients such as ethanol were reported to be related to the above adverse events. Hand disinfectants containing glycerin, silicone oil, vitamin B, plant extracts and other emollients could reduce the incidence of adverse events. ConclusionCurrent evidence shows that hand disinfectants containing emollients and free from ethanol, chlorhexidine and other ingredients are related to fewer adverse events. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.

    ObjectivesTo explore the construction method of prediction model of absolute risk for breast cancer and provide personalized breast cancer management strategies based on the results.MethodsA case-control design was conducted with 2 747 individuals diagnosed as primary breast cancer by pathology in West China Hospital of Sichuan University from 2000 to 2017 and 6 307 healthy controls from Breast Cancer Screening Cohort in Sichuan Women and Children Center and Chengdu Shuangliu District Maternal and Child Health Hospital. Standardized questionnaires and information management systems in hospital were used to collect information. Decision trees, logistic regression, the formula in Gail model and registration data in China were used to estimate the probability of 5-year risk of breast cancer. Eventually a ROC (receiver operating characteristics) curve was drawn to identify optimal cut-off value, and the power was evaluated.ResultsThe decision tree exported 4 variables, which were urban or rural sources, number of live birth, age and age at menarche. The median 5-year risk and interquartile range of the controls was 0.027% and 0.137%, while the median 5-year risk and interquartile range of the cases was 0.219% and 0.256%. The ROC curve showed the cut-off value was 0.100%. Through verification, the sensitivity was 0.79, the specificity was 0.73, the accuracy was 0.75, and the AUC (area under the curve) was 0.79.ConclusionsThe methods used in our study based on 9 054 female individuals in Sichuan province could be used to predict the 5-year risk for breast cancer. Predictor variables include urban or rural sources, number of live birth, age, and age at menarche. If the 5-year risk is more than 0.100%, the person will be judged as a high risk individual.
