Objective:
To investigate the healthcare expenditures and self-payment among patients with lung cancer in Wenling City before and after implementation of diagnosis-related groups (DRGs), so as to provide the evidence for controlling medical costs and relieving burdens of patients with lung cancer.
Methods:
The basic data and healthcare expenditures of lung cancer patients that were definitively diagnosed from 2015 to 2019 and covered by medical insurance were captured from the cancer registration database of Wenling Center for Disease Control and Prevention and the database of chronic and specific diseases in Wenling Bureau of Medical Insurance. The changes of outpatient expenditures, inpatient expenditures and self-payments were compared before (2015-2016) and after implementation of DRGs (2018-2019) among lung cancer patients.
Results:
Totally 4 947 lung cancer patients covered by medical insurance were enrolled in this study, including 3 052 males (61.69%) and 1 895 females (38.31%), with a mean age of (64.88±11.64) years. The annual mean healthcare expenditure was 56 675.85 Yuan per capita during the period between 2015 and 2016, in which 14.48% were outpatient expenditures and 85.52% were inpatient expenditures, and the annual mean healthcare expenditure was 38 702.94 Yuan per capita during the period between 2018 and 2019 (a 31.71% reduction as compared to that in 2015 and 2016), in which 24.49% were outpatient expenditures and 75.51% were inpatient expenditures. The proportions of outpatient expenditures, inpatient expenditures and total self-payments consisted of 25.38%, 32.49% and 29.67% of total healthcare expenditures in 2018 and 2019, which were significantly lower than those (50.84%, 50.96% and 50.95%, respectively) in 2015 and 2016 (χ2=13.741, P<0.001; χ2=7.015, P=0.008; χ2=9.340, P=0.002).
Conclusions
The annual mean healthcare expenditures per capita and the proportion of self-payment reduce among lung cancer patients covered by medical insurance following implementation of DRGs.

Objective:To assess the relationship between serum total bilirubin and fundus arteriosclerosis in different genders.Methods:The physical examination data of Huadong Sanatorium in 2018 were analyzed, and a total of 26 275 people were included in this retrospective cross-sectional study. The age of this study was 18-86 (47.7±11.1) years old. Among them, there were 15 244 males (58.02%) and 11 031 females (41.98%). Participants were divided into 4 groups according to total bilirubin quartile values: Q1<11.50 μmol/L, Q2∶11.50-13.93 μmol/L, Q3∶13.94-17.14 μmol/L and Q4>17.14 μmol/L. The relationship between total serum bilirubin and fundus arteriosclerosis is determined using univariate and multivariate logistic regression analysis methods. The restricted cubic spline method was used to detect the dose-response relationship between total bilirubin and fundus arteriosclerosis. Results:In males, univariate analysis showed that high level of total bilirubin was a protective factor for fundus arteriosclerosis ( OR=0.87, 95% CI 0.78-0.97, P=0.012). After adjusting for other confounding factors, multivariate analysis showed that high level of total bilirubin remained as an independent protective factor for fundus arteriosclerosis ( OR=0.86, 95% CI 0.74-0.99, P=0.047). There was a linear dose-response relationship between total bilirubin level and fundus arteriosclerosis ( P=0.012). In females, univariate analysis showed that there were no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.96, 95% CI 0.80-1.17, P=0.709). After adjusting for other confounding factors, multivariate analysis showed no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.98, 95% CI 0.76-1.27, P=0.888). No linear dose-response relationship between total bilirubin level and fundus arteriosclerosis was found in females ( P=0.253). Conclusion:There are gender differences in the relationship between total bilirubin and fundus arteriosclerosis in this cohort. Elevated levels of total bilirubin are associated with fundus arteriosclerosis in males but not in females.

ObjectiveTo investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma (HCC). MethodsA retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1, 2019 to March 31, 2021, and all patients received camrelizumab monoclonal antibody treatment, among whom 84.8% also received targeted therapy. According to the age of the patients, they were divided into elderly group (≥65 years) and non-elderly group (<65 years). The two groups were assessed in terms of overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and immune-related adverse events (irAE). The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; the independent samples t-test was used for comparison of normally distributed continuous data, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for comparison of survival curves. Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months. ResultsA total of 99 HCC patients were enrolled, with 27 in the elderly group and 72 in the non-elderly group. The elderly group had an OS rate of 67.8%, an ORR of 44.4%, and a DCR of 74.1% at 12 months and a median PFS of 6.4 (95% confidence interval [CI]: 3.0 — 12.4) months, with no significant differences compared with the non-elderly group (all P>0.05). The median OS was unavailable for the elderly group, while the non-elderly group had an OS of 18.9 (95%CI: 13.0 — 24.8) months; there was no significant difference between the two groups (P=0.485). The univariate and multivariate Cox regression analyses showed that major vascular invasion (MVI) was an independent risk factor for PFS (hazard ratio [HR]=2.603, 95%CI: 1.136 — 5.964, P=0.024) and DCR (HR=3.963, 95%CI: 1.671 — 9.397, P=0.002) at 6 months, while age, sex, etiology of HBV infection, presence of extrahepatic metastasis, Child-Pugh class B, and alpha-fetoprotein>400 ng/mL were not associated with PFS or DCR at 6 months. For the elderly group, the incidence rates of any irAE and grade 3/4 irAE were 51.9% and 25.9%, respectively, with no significant differences compared with the non-elderly group (P>0.05), and skin disease was the most common irAE in both groups (39.4%). ConclusionCamrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged ≥65 years and those aged <65 years. MVI is associated with suboptimal response to immunotherapy and poor prognosis.
