IntroductionA retrospective review conducted in three hospitals of Guangdong and Hainan, China. To analyze the variation tendency of mean hospitalization costs and length of stay (LOS) in naval hospitals over nine years, paying special attention to the factors affecting hospitalization costs and LOS to provide a reference base for health resource allocation in naval hospitals.Materials and MethodsA total of 21,375 cases of military patients who were hospitalized and treated in three naval hospitals between January 2008 to December 2016 were extracted from the military health system. There were 16,278 complete and effective cases during those nine years. The situation, trends, and factors influencing hospitalization costs and LOS were analyzed using descriptive statistics, Mann-Whitney U test, Kruskal–Wallis H test, and multiple linear regressions.ResultsThe following factors showed statistically significant differences in hospitalization costs: special care, primary care, year, military rank, critical illness, allergies, and condition (p < 0.0001); and number of hospitalizations, gender, and age (p < 0.01). The following factors showed statistically significant differences in hospital LOS: year, number of hospitalizations, outcomes, military rank, special care, severity of illness, and condition (p < 0.0001); allergy (p < 0.01); and service and gender (p < 0.05). LOS between 2008–2016 showed a decreasing tendency, while hospitalization costs showed an increasing trend. There were 6 factors that affected Abstract (or Structured Summary) both the cost of hospitalization and LOS: special care, year, military rank, condition, allergy, and gender.ConclusionsThe results suggest that improving efficiency of military hospital require strengthening hierarchical referrals and controlling hospital LOS. Shortening LOS, optimizing clinical pathways, and reasonably controlling the costs associated with medicines and surgery can help reduce hospitalization costs for military patients. Controlling the growth of hospitalization costs can help avoid the physical and psychological burden of medical over-treatment on patients and may also optimize the allocation of military health resources.
Introduction To assess the self-perceived mental health of soldiers and officers in the submarine force in the South China Sea, the result of this investigation was compared to the Chinese military male norms, and the factors that influence their mental health was further explored. Materials and Methods A total of 580 male submariners agreed to participate. In the final analysis, 511 valid questionnaires were included; 69 incomplete questionnaires were excluded. The Symptom Checklist 90 (SCL-90) was used to measure the self-perceived mental health of the officers and soldiers. Results The scores of four dimensions (somatization, anxiety, phobic anxiety, and paranoid ideation) and the average of the total SCL-90 scores for the submarine force in the South China Sea were significantly higher than the Chinese military norms. Age and length of service were found to be protective factors, with 26- to 30-year-old age group (adjusted odds ratio [AOR] = 0.365, 95% CI = 0.138-0.961) and individuals with 6 to 10 years of service (AOR = 0.357, 95% CI = 0.151-0.842) having lower odds of poor mental health. Education level (bachelor’s degree) and workplace (nuclear submarine) were found to be risk factors. Conclusions This study demonstrates for the first time that soldiers and officers in the submarine force in the South China Sea are exposed to a number of mental health risks and are suffering from serious psychological problems. These findings provide a basis for military departments to effectively address these psychological problems.
Objectives:To study injury patterns and medical rescue operations related to tornadoes that occur in rural areas, this study investigated the data pertaining to the 2017 Chifeng tornado (China).Methods:Medical records of 52 tornado-related patients were investigated. Data were collected from 3 local hospitals that received all the tornado victims.Results:A total of 148 injuries were diagnosed. Tornado-related injuries were mainly caused by collapsed houses (51.9%) and direct physical trauma caused by the tornado (38.5%). Most injuries occurred outdoors (63.5%). The head (20.3%) and thorax (14.8%) were most 2 frequent anatomical injury sites. Soft-tissue injuries (43.9%) and contusions and lacerations (37.3%) were the 2 most common injury types. On evaluating the Abbreviated Injury Scale scores, a score of 1 was the most common (66.2%), and a score of 6 was not recorded.Conclusions:A trailing phenomenon in the distribution of time to admission among the victims of a particular tornado in China was observed. The delivery is timely compared with nondisaster situation. There was a statistically significant difference of injury causes between outdoor and indoor patients. Helmets should be used by potential tornado victims. Basement units capable of functioning as shelters should be built in villages.
