(1) Background: Studies have reported that COVID-19 may increase the risk of malnutrition among patients. However, the prevalence of such risk in hospitalized COVID-19 patients is uncertain due to the inconsistent use of assessment methods. (2) Methods: PubMed, Web of Science, and EMBASE were searched to identify studies on the nutritional status of hospitalized COVID-19 patients. A pooled prevalence of malnutrition risk evaluated by Nutrition Risk Score (NRS-2002) was obtained using a random effects model. Differences by study-level characteristics were examined by hospitalization setting, time of assessment, age, and country. Risk of bias was assessed using the Newcastle–Ottawa Scale. (3) Results: 53 studies from 17 countries were identified and summarized. A total of 17 studies using NRS-2002, including 3614 COVID-19 patients were included in the primary meta-analysis. The pooled prevalence of risk of malnutrition was significantly higher among ICU patients (92.2%, 95% CI: 85.9% to 96.8%) than among general ward patients (70.7%, 95% CI: 56.4% to 83.2%) (p = 0.002). No significant differences were found between age groups (≥65 vs. <65 years, p = 0.306) and countries (p = 0.893). (4) Conclusions: High risk of malnutrition is common and concerning in hospitalized patients with COVID-19, suggesting that malnutrition screening and nutritional support during hospitalization are needed.

ObjectiveTo analyze the impact of the contract of family doctors in community-level in Beijing on residents’ medical expenses, so as to explore the efficacy of family physician contract service to facilitate the hierarchical treatment system. This study pioneeringly used the panel data of medical records and medical insurance settlement details provided by a community hospital in Beijing. By analyzing the correlation between family doctors and medical expenses, the study provided empirical support for the advancement of family doctor contracting in China.MethodsUsing the panel data of medical records and medical insurance settlement details of 5,851 residents in a community hospital in Beijing from January 2018 to May 2021 for a total of 41 months, mixed-effects model and random-effects model were used for analysis.ResultsThe contract of family doctor has significantly increased residents’ medical expenses. The types of medical insurance and whether patients with chronic diseases have a significant impact on residents’ medical expenses.ConclusionFamily doctor contracting increases the probability of residents seeing a doctor in community hospitals. Community family doctor contracting services should be vigorously promoted, especially for special groups such as chronic disease patients and the elderly. The increase in the contracting rate of family doctors will become an important starting point for promoting hierarchical medical system and increasing the primary treatment at the community-level.

Objective Unequal utilization of medical services will have a significant impact on the consumption of resources entitled through health insurance claims of patients. With the proposal of the goal of Healthy China, it is essential to achieve the equity of medical service utilization of patients with rare diseases to further promote social equity and justice. To analyze the consumption of medical resources of rare disease patients, so as to explore how different medical insurance types impact patients’ medical resources consumption. This study pioneeringly used medical data from Peking Union Medical College Hospital. By analyzing the consumption data, this paper fills the research gap of existing studies on the analysis of medical service utilization inequality based on the perspective of insurance participation by examining the effects of different types of insurance coverage on medical resource consumption of hemophiliacs. At the same time, rare disease patients as a minority group have long been neglected in the analysis of medical resource consumption, and this paper fills the research gap of medical service utilization of this group to a certain extent by taking hemophiliacs as the object of analysis. Methods Based on the medical data of hemophilia patients in Peking Union Medical College Hospital from 2010 to 2020, we analyze the consumption of medical resources of the patients, and use a multiple regression model to explore how different medical insurance types impact patients’ medical resources consumption. Results The study has three main findings. Firstly, the disparity in medical expenditure among different hemophilia patients is quite obvious, and the drug expense accounts for a large proportion of the total cost. Secondly, the ratio of reimbursement is generally low, and there is a wide difference in the amount of reimbursement for different types of medical insurance. Thirdly, the resource consumption of patients with different medical insurance types differs a lot. Conclusion In order to improve the current medical insurance system and mechanism for providing orphan drugs, we put forward the following suggestions. First of all, the medical security system should expand its coverage to eliminate the medical expenditure gap between different hemophilia patients, therefore better promoting equity under the same insurance type. At the same time, the reimbursement level of medical expenses for patients with rare diseases should be appropriately improved, so as to reduce the financial burden of patients with rare diseases, and promote the realization of economic equity. In addition, society should pay special attention to the disadvantaged groups, reduce the differences between various medical insurance, and improve the level of health and equity of the whole society.
