ABSTRACT
Objective To compare the clinical choosing principles of sedated colonoscopy with con-ventional colonoscopy. Methods Outpatients who were willing to accept colonoscopy with or without seda-tion were prospectively recruited,which were assigned to sedated colonoscopy group(n=362)and conven-tional colonoscopy group(n=323). All patients and endoscopists were asked to answer a self-administered questionnaire. The colonoscopy completion,operation time,procedure-related discomfort,and questionnaire results of the two groups were compared and statistically analyzed. Results The completion rate was 98. 9%in the sedated colonoscopy group(358/362)and 89. 8% in the conventional colonoscopy group(290/323) ( P=0. 337 ). The operation time of sedated and conventional group were( 5. 60 ± 3. 25 ) minutes and (7. 71 ± 5. 70)minutes respectively(P<0. 001). And the average cost was CNY 886. 54 per patient in se-dated group and CNY 386. 00 per patient in the conventional group. Patient satisfaction score of conventional group and sedated group were 4(3-4)and 3(2-3)points(P<0. 001),while endoscopist satisfaction score was 4(3-4)and 4(4-4)(P<0. 001). A total of 354 patients(97. 79%)in the sedated group and 225 pa-tients(69. 66%)in the conventional group showed willingness to repeat the identical colonoscopy( P <0. 001). Patients who were male(P=0. 035),having no past abdominal operations(P<0. 001),or no ab-dominal pain during colonoscopy( P =0. 015 )in the conventional group preferred to repeat conventional colonoscopy. Conclusion Although the examination time of conventional colonoscopy is longer than sedated colonoscopy,it could reduce anesthesia risk and the cost. Conventional colonoscopy remains an irreplaceable examination of colorectal diseases in developing countries. Physicians should not only focus on patients'com-fort during endoscopy,but also help patients make a decision based on their actual situation and endoscopic indications to make the best of medical resources.
ABSTRACT
<b>Introduction:</b> The outbreak of severe acute respiratory syndrome (SARS) began in Guangdong, China in November 2002 and spread to Hong Kong around March 2003. It stopped spreading in July of the same year. However, a sense of crisis toward potential new infections may exist in epidemic areas. “College-prep students” are regarded as a high-risk group as a source of infection because of certain factors, such as the differences in linguistic capabilities and their customs. The purpose of this study was to clarify the knowledge, attitude, and behavior toward SARS, and also to collect the information as baseline data for the control of emerging infectious diseases toward them.<br><b>Methods:</b> We conducted a self-administered questionnaire to 303 “college-prep students” from June 27 to July13, 2003. For statistical analyses, the chi-square test, t-test and factor analysis were used.<br><b>Results:</b> The average age of subjects was 22.8 years for males, and 22.6 years for females. The majority of subjects was from China (76.8%, n= 218), and had only stayed in Japan less than one year (70.9%, n= 205). Most subjects were knowledgeable of the symptoms of and preventative measures for SARS. There were no significant differences in knowledge, attitude, and behavior items between students from epidemic areas and those from non-epidemic areas. However, we observed a statistically significant difference in the proportion of subjects in the two groups stratified by information source: radio (p<0.01) and family (p<0.05), where the proportion was higher in epidemic areas than in non-epidemic areas. Three factors were extracted by factor analysis on information sources, which suggested an inverse correlation for language and frequency of communication.<br><b>Conclusions:</b> This study clarified the knowledge, attitude, and behavior toward SARS for “college-prep students”. These findings must be useful for the control against emerging infectious diseases.
