OBJECTIVE:To provide reference for clinical rational drug use. METHODS:Medication error(ME)cases report-ed from outpatient department from Oct. 2014 to Sept. 2015 in our hospital were analyzed,including ME category,classification, cause and proportion of persons who triggered or detected ME. RESULTS:Among 207 reports,there was no case of category A, 199 cases of category B,8 cases of category C,no of categories D-I. Among them,162 cases occurred in the links of prescrip-tions by doctors (78.26%),45 cases (21.74%) occurred in the links of dispensing prescriptions by pharmacists,the top 3 ME were improper usage(42.59%),improper administration route(40.74%)and inappropriate solvent(5.56%);the top 3 dispensing errors were variety error(40.00%),specification error(28.89%)and number errors(24.44%). The main causes for prescription errors were incomplete information system(56.17%)and drug information missing of doctors(43.83%);the main causes for dis-pensing errors were double specifications of drugs(35.56%),similar drug name(28.89%)and staffsntired(26.67%). In terms of the persons who triggered ME,the proportions of pharmacists,nurses,patients or their families were 97.58%,1.45% and 0.97%, respectively. CONCLUSIONS:Further strengthening information system and the on-the-job training for physicians and pharmacists can reduce the ME to some extent.

Objective:A study was conducted to observe and compare the efficacy and safety of endostar combined with peme-trexed in elderly patients with advanced lung adenocarcinoma. Methods:Sixty advanced lung adenocarcinoma (ⅢB-Ⅳ) patients who never received any therapy were included. The patients were divided into two groups. One group comprised endostar treatment com-bined with pemetrexed (26 cases of males, 15 cases of females, and 11 cases of individuals aged 65 years old to 78 years old), and the other group comprised pemetrexed only (34 cases of males, 20 cases of female, and 14 cases of individuals aged 65 years old to 78 years old). The two groups were treated for 4 to 6 cycles, and evaluation of treatments was performed every two cycles. Results:The endostar group was re-treated for 80 cycles, and the average cycle was 3.1. The group without endostar was re-treated for 115 cycles. The short-term effects are as follows. The total effective rates (RRs) in the experimental and control groups were 23.1%and 14.7%, re-spectively, and the difference was statistically significant (P<0.05). The disease control rate (DCR) was not significantly different (P>0.05). For pleural effusion, RR and DCR were significantly better in the experimental group than in the control group (P<0.05). In the experimental group, compared with PD, the microvessel density (MVD) in the DCR showed higher expression, and a statistically signif-icant difference (P=0.03) was observed. In the control group, compared with PD, the MVD in the DCR also showed higher expression, but no significant difference (P=0.73) was observed. The long-term effects were as follows: median progression-free survival (PFS), median survival, and side effects between the two groups were not significantly different (P>0.05). Conclusion: Endostar combined with pemetrexed showed increase in total efficiency in elderly patients with lung adenocarcinoma, and malignant pleural effusion was controlled without increasing the toxicity of chemotherapy. MVD can be used as a predictor of Endostar application.
