RESUMEN
@# Objective To analyze the disease burden caused by occupational coal workers' pneumoconiosis (CWP) in Anhui Methods Province. A total of 1 649 patients with occupational CWP diagnosed in Anhui Province from 1950 to 2019 were selected as the study subjects using a retrospective study method. Age, gender, survival time, location, working age of disease onset, age of death, stage and date of diagnosis of CWP, comorbidities at the time of investigation, hospitalization and outpatient expenses in the past year, cost of absence from work, cost of absence from work of caregivers, and cost of nutrition and transportation were investigated. The years of life lost, years lived with disability (YLDs), disability adjusted life years (DALYs) Results and economic losses were calculated. Among these patients, 1 405 cases survived and 244 cases died. In the age range - - - of 20.0 70.0 years, the YLDs of surviving patients were 2.12 22.20 (8.19±3.59) person years. The YLDs of patients with disease vs - P complications was higher than that of patients without complications [(8.55±3.95) (7.87±3.21) person years, <0.01]. The total - - DALYs of the patients was 14 031.59 person years, and the average per capita DALYs was 8.51 person years. Its YLDs accounted for 82.0 % of the total DALYs. The total economic loss caused by CWP in the 1 405 surviving patients was 354.903 0 Conclusion million yuan, and the average per capita economic loss was 252 600 yuan. The disease burden caused by CWP is relatively high in Anhui Province. In addition to early detection, diagnosis and treatment, it is necessary to focus on prevention and treatment of CWP complications to reduce the disease burden.
RESUMEN
OBJECTIVE: Suggestions and training in developing a computer software for analysis of arterial blood gases in treatment to be used in clinic and teaching. METHODS: The software was edited by means of Delphi 7.0 and closely combined with Windows operating system. The knowledge base was built with Microsoft Access and HTML format files. The treatment suggestions and knowledge base of the software were built according to the correlated diagnosis and treatment guidelines of Chinese Medical Association, Practical Medicine (edition 12) edited by CHEN Hao-zhu, Medicine (edition 6) edited by YE Ren-gao, Modern Clinical Blood Gases Analysis edited by QIAN Gui-sheng, Concise Clinical Blood Gas Analysis edited by LUO Yan-jie, and the experience of the experts of our hospital. RESULTS: (1)The model of treatment suggestions consisted of the treatment objective and the treatment suggestions,and its contents included simple acid-base disturbance, mixed acid-base disturbance, respiratory failure,metabolic disturbances of sodium potassium and chloride. The calculation formulae included calculation formulae for the correction of acid-base disturbance and electrolyte disturbance. (2)Arterial blood gas analysis training software contained knowledge database of arterial blood gas analysis, clinical opinions of arterial blood gas analysis, exam database of arterial blood gas analysis, knowledge of arterial blood gas analysis graph, calculation formulas, correlated books and websites,assistance and so on. CONCLUSION: The software could be used as a reference by clinical doctors in clinic, it could also be used for teaching and training. It is scientific, state-of-the art, and valuable in clinical practice.
