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 investigate the current application of colonoscopy at hospitals in China.Methods:From November 2019 to January 2020, an online questionnaire survey was conducted among gastroenterologists and colonoscopists in hospitals of different levels. The contents of questionnaire survey included basic information of colonoscopy at the respondent′s hospital, protocols and patient education of bowel preparation, implementation of colonoscopy quality control, and colonoscopists′ understanding of polypectomy techniques and post-polypectomy follow-up.Results:A total of 236 valid questionnaires were collected, involving 187 hospitals, and 143 (76.5%) had an annual operation capacity of more than 5 000 cases. In terms of bowel preparation, split-dosed polyethylene glycol electrolyte powder (PEG) was the most commonly used (60.4%, 113/187) and the most common volume of PEG was 3 L (67.4%, 126/187). Verbal (90.9%, 170/187) and written (79.7%, 149/187) instructions were given more often than other methods for patient education of bowel preparation. Antifoaming agent was routinely used in 124 (66.3%) hospitals. In terms of quality control, only 11.5% (20/174) hospitals implemented all four measures. In terms of polypectomy techniques, 98.1% (203/207) colonoscopists chose hot snare polypectomy or endoscopic mucosal resection for lesions of diameter>1 cm, while options varied for lesions of diameter<1 cm. The interval of follow-up after polypectomy recommended by colonoscopists was shorter than that by guidelines.Conclusion:Several problems are found in the survey in the application of colonoscopy in China, i. e., patient education of bowel preparation is not diversified; quality control of colonoscopy still needs to be strengthened; polypectomy techniques and follow-up after polypectomy need to be further standardized.

Objective:To explore the problems of medical and preventive integration at primary healthcare institutions in China, for references for promoting the development of medical and preventive integration in China.Methods:This study searched for literatures covering the integration of medical and preventive at primary healthcare institutions on CNKI, Wanfang, and VIP databases(from the establishment of the database until March 1, 2023), and extracted text mentioning problems of the medical and preventive integration in primary healthcare institutions. The macro model of the health system was used for problem classification analysis, while the social network analysis method was used to measure the network density, point centrality, and intermediary centrality of the problem, and determine the key issues.Results:A total of 25 papers were included, and 28 problems of medical and preventive integration at primary medical and health institutions were extracted, including 6 problems at the external environment level, 15 problems at the structural level, 6 problems at the process level, and 1 problem at the result level. The results of social network analysis showed that the network density of these problems was 0.71. The point centrality and intermediary centrality of key problems were both high, including the lack of incentive mechanisms for medical and prevention integration (point centrality=69, intermediary centrality=21.44), fragmentation of health information systems(68, 15.70), insufficient awareness of medical and prevention integration among grassroots personnel(65, 17.47), shortage of talent at primary medical and health institutions(64, 11.69), weak service capabilities of primary medical institutions(50, 19.23), and insufficient information sharing(48, 15.80).Conclusions:A variety of problems were found in the integration of medical and preventive at primary medical and health institutions in China, which were closely interrelated. It was urgent to solve six key problems, including the lack of incentive mechanisms, talent shortage, and information system fragmentation, etc. It was suggested that primary medical and health institutions should further improve the incentive mechanism for medical and preventive integration, strengthen the construction of grassroots health talent teams, promote health information exchange and sharing, and enhance the awareness of medical and preventive integration.

Objective:To explore the safety and effectiveness of laparoscopic local pancreatectomy in the treatment of cystic neoplasms of pancreatic head.Methods:Retrospective analysis was conducted of data on patients with pancreatic head cystic neoplasms who received laparoscopic surgery at the Department of Hepatobiliary Surgery, the Second Hospital of Hebei Medical University from February 2017 to October 2022. A total of 83 patients were enrolled, including 30 males and 53 females, aged (43.7±16.7) years old. All patients were divided into an observation group ( n=55) and a control group ( n=28) based on different surgical procedures. The observation group underwent laparoscopic local pancreatectomy (laparoscopic duodenum-preserving pancreatic head resection or laparoscopic enucleation), while the control group underwent laparoscopic pancreaticoduodenectomy (LPD). The age, gender, body mass index, postoperative hospital stay, proportion of discharged patients with drainage tubes, surgical time, intraoperative blood loss, intraoperative blood transfusion rate, and fistula were compared between two groups. Results:All patients successfully completed the surgery, and there were no cases of conversion to laparotomy or perioperative deaths. There was no statistically significant difference in age, male proportion, body mass index, postoperative hospital stay, and discharge rate with drainage tube between the two groups of patients (all P>0.05). The observation group had a surgical time of (194.4±114.0) min, intraoperative bleeding of 50 (50, 200) ml, and intraoperative blood transfusion rate of 5.5%(3/55), all of which were better than that of the control group, (380.0±71.6) min, 200 (100, 400) ml, and 32.1%(9/28), with statistical significance (all P<0.05). Among them, the B/C fistula rates in the laparoscopic local pancreatectomy group and LPD group were 12.7%(7/55) and 10.7%(3/28) ( P=0.790), respectively. Conclusion:Compared with traditional LPD, laparoscopic local pancreatectomy can shorten surgical time, reduce intraoperative bleeding, and lower intraoperative blood transfusion rate. And there is no significant disadvantage in the B or C grade fistula.
