    Objective To provide baseline date for further research by retrospectively investigating the disease constitution of over-60-year old patients in the West China Hospital of Sichuan University in 2011. Methods The information of over-60-year old outpatients was extracted from HIS and their diagnoses were classified by ICD-10. The data of single disease among top 3 categories of diseases were rearranged and analyzed by Excel software. Results The total of over-60-year old outpatients was 895 123 person-time in 2011, accounting for 19.65%, including 716 826 person-time in specialist outpatient clinics. The specialist diagnoses of 683 491 person-time could be classified by ICD-10, accounting for 95.35% of specialist outpatients. The top 12 diseases were neoplasm, circulatory, digestive, factors influencing health status and contacting with health services, respiratory, musculoskeletal system and connective tissues, nervous, eyes, symptoms/signs and abnormal clinical and laboratory findings, non-classified, mental and behavioral disorders, endocrine, and genitourinary system diseases, and the cumulative constituent ratio was 92.96%. The main pathogenic sites of neoplasm were bronchus and lung (21.98%), esophagus (8.66%), stomach (8.10%), rectum (7.37%), prostate (5.86%), and liver and intrahepatic bile ducts (5.55%), with a cumulative constituent ratio of 57.72%. The main disease burden in circulatory system was hypertension (39.50%), chronic ischaemic heart disease (11.17%), and cerebral infarction (9.70%), and the cumulative constituent ratio was 60.38%. While the main disease burden in digestive system was gastritis and duodenitis (24.98%), other diseases of digestive system (9.26%), and other diseases of liver (8.90%), and the cumulative constituent ratio was 43.13%. There were more female than male among the over-60-year old outpatients (50.67% vs. 49.33%), and male was higher than female only in the incidence of neoplasm, respiratory, factors influencing health status and contacting with health services, and genitourinary system diseases. The disease constitution ratio of 60-69 years old patients was 58.21%. The top 3 neoplasm were the malignant tumors in digestive (38.20%), respiratory and intrathoracic organs (24.70%), and lymphoid, haematopoietic and related tissue (11.97%), with a cumulative constituent ratio of 74.87%. Conclusion The top 3 disease burden of over-60-year old outpatients in West China Hospital were neoplasm, circulatory and digestive diseases, which reflects the trend and law of treatment demands of old patients. It needs to deeply analyze the frequency and flow pattern of patients, and to provide evidence for preventing and treating geriatric diseases.

  • Costs of Emergency Medication in West China Hospital within One Month after Lushan Earthquake

    Objective To analyze the costs of emergency medication in the West China Hospital within one month after Lushan earthquake based on actual medication of the victims’ disease spectrum. Methods We collected emergency medication data as evaluation index in the West China Hospital within one month after Lushan earthquake, including daily cost, cumulative percentage of pharmacology category, average cost per day/person, average cost per day/person when DUI=1, difference between average cost per day /person, and average cost per day/person when DUI=1, etc. Then, we input data using Excel software for statistically analyzing the costs of emergency medication within one month after the earthquake. Results During one month after the earthquake, the costs changed consistently with the number of victims, which implied the change of costs was rational. Injuries were classified into 6 categories and 12 kinds according to ICD-10. The costs of medication accounted for 71% of the total costs. Six kinds of illness accounted for 21%. Medication for injuries was classified into 3 categories and 18 kinds; average cost per day was 186.87 yuan and average cost per person was 1 702.70 yuan. Medication for illness was classified into 5 categories and 28 kinds; average cost per day was 38.96 yuan and average cost per person was 185.13 yuan. The mean value of average cost per day/person of injection was 14.52/5.08 times more than that of non-injection. Meanwhile, the mean value of average cost per day/person of imported medication was 7.10/5.28 times more than that of domestic medication. Conclusion The factors that impact the medication costs include: a) disease burden and traumatic conditions of the sick and wound; b) administration pathway (injection vs. non-injection); c) imported or domestic medication; and d) the rationality of taking DUI as evaluation index. When DUIgt;1, injection through the vein and imported medication take a larger share which increase the costs of medication. Emergency rescue package should mainly prepare for the injury. In order to ensure the timely, safe and effective medication, injection should be given priority to. We also should take into consideration crash-resistance/anti-quake package, reasonable dosage, convenience-to-use of drugs as well as the needs of the illness.

  • Rationality of Emergency Medication in the West China Hospital within One Month after Lushan Earthquake

    Objective To analyze the rationality of emergency medication in the West China Hospital after Lushan earthquake based on the actual drug use of earthquake victims. Methods We applied DDDs and DUI as evaluation index, input data using Excel software, and analyzed if the emergency medication was required for the injury/illness and the rationality of emergency medication. Results Earthquake victims mainly had trauma and wound infection and they were given antibiotics as main treatment one week after the earthquake. Drugs for the respiratory system and digestive system were mainly used in patients who mainly manifested as non-traumatic diseases and internal diseases four weeks after the earthquake. Among 49 kinds of drugs which could be calculated for the value of DUI, injection accounted for a larger proportion than non-injection (59.18% vs. 40.82%). The results showed that, the medication (DUI=1) only accounted for 12.24%; the medication (DUIlt;1, Mean=0.65) accounted for 38.78%, which implied insufficient drug use; the medication (DUIgt;1, Mean=1.77) accounted for 46.94%, which implied drug overuse. Conclusion Medication for every system is basically timely and rational when treating symptoms and causes in the West China Hospital within one month after Lushan earthquake. However, the rationality of emergency medications using DUI=1 under normal conditions still needs to be further verified.

  • History and Research Advance of China-made Mechanical Heart Valves

    Clinical application history of prosthetic heart valves has been over five decades, and mechanical heart valves have satisfactory clinical outcomes for surgical treatment of valvular heart disease. The development history of mechanical heart valves experienced from the first generation of ball valves and caged disc valves to the second generation of single tilting disc valve, and to the third generation of bileaflet valves. In 1960, ball valve was first used for heart valve replacement in abroad. In 1963, China-made ball valve was also produced and used in clinical practice. In 1969, the second generation of single tilting disc valve was developed in abroad. In 1978, China-made single tilting disc valve was produced and widely used in clinical practice with satisfactory clinical outcomes. Since 1980 when it was first produced, bileaflet valve has taken the place of above 2 types of valves for its excellent performance, and become the mainstream product all over the world. Currently, the development of China-made bileaflet valves has lagged behind, and domestic mechanical heart valve market has almost been monopolized by foreign bileaflet valve products. Therefore, the development of ideal China-made mechanical heart valve deserves further research.
