Résumé
Objective To understand the morbidity of human brucellosis in Wulanchabu City of Inner Mongolia in order to provide a basis for development of prevention and control measures.Methods According to the requirements in Baseline Survey Programme of Human Brucellosis in Inner Mongolia Autonomous Regionbetween November and December in 2010,stratified cluster sampling method was used to selected three townships according to the conditions of brucellosis(mild,moderate and serious) in 11 flags(cities,counties,districts) of the city.Three villages were extracted from each township.There were at least 200 persons aged 10 and older were investigated in every township.At least 600 people were investigated in every flag(city,county,district).Respondents were investigated about their awareness rate of basic knowledge about brucellosis,risk factors and common sense of prevention and treatment of the disease by using health education questionnaire.Based on the principle of informed consent,we collected respondents venous blood for preliminary screening using Hu red tablets.Brucellosis was confirmed with standard tube agglutination test and positive result was confirmed if 1:100 antibody concentration was two + or more.Prevalence,false negative rate as well as different age,gender,occupational incidence was calculated based on the network reported results of brucellosis in 33 townships of Wulanchabu in 2010.Results We distributed 6998 questionnaires and 6763 questionnaires were effective.The witting rate of basic knowledge about brucellosis was 57.99％(15 687/27 052); the witting rate of risk factors about brucellosis was 44.33％ (29 978/67 630); the witting rate for prevention and control of brucellosis was 41.66％(28 176/67 630),and total witting rate was 45.49％(73 841/162 312).The morbidity of brucellosis in Wulanchabu City was 91.39/10 000 (785/85 894) in 2010.Five hundred and ninety-one were serologically positive and the infection rate was 8.48％ (591/69 972).Nine hundred and three cases of patients were diagnosed with brucellosis and the prevalence rate of brucellosis was 105.13/10 000 (903/85 894).Missing report 377 cases,and the false negative rate was 48.03％ (377/785) in 2010.Men infection rate was 71.07％(420/3755) and women infection rate was 28.93％(171/3217).The infection rate[97.63％(577/591)] of people aged 31 and older was significantly higher than that [2.37％(14/591)] of the people aged 30 and younger.Infection rate of people engaged in aquaculture was 8.61％ (582/669).The infection rate of people working in livestock processing industry was 2.91％ (2/103).The infection rate of people working in animal by-product circulation was 2.85％ (2/70).The Infection rate of people working in other industries was 4.59％(5/109).Conclusions In Wulanchabu City,the morbidity of brucellosis and missing report rate are both high.The infection rate of people engaged in aquaculture is high and man morbidity is high.The awareness rate about prevention and treatment knowledge of brucellosis is low.We should carry out health education to inhabitants in endemic areas to improve their self-protection awareness and reduce the incidence of brucellosis.
Résumé
OBJECTIVE To reduce the missing report rate of nosocomial infection(NI) by establishing relevant surveillance protocol,improve the early warming system of NI,and therefore prevent the outbreak and prevalence of NI.METHODS Based on Nosocomial Infection Diagnosis Standard published by Chinese Ministry of Health in 2001,116 213 patient data from Jan 2000 to Dec 2006 had been reviewed;factors associated with NI missing report rate had been reevaluated;measures to reduce the rate had been made;and the feedback information of NI control had been collected.Meanwhile,according to high risk factors provided by the hospital information system,the prospective investigations had been made.Surveillance protocol had been established as above.RESULTS By the implementation of the protocol,the missing report rate of NI had been under control,lower than the standard rate of 20% for tertiary hospitals.In 2005,the protocol was reinforced and the NI missing report rate had been reduced to 7.4% by 2006.CONCLUSIONS The real-time monitoring of NI cases is an effective way in reducing missing report rate of NI.
Résumé
OBJECTIVE To analyze the nosocomial infection cases,which were failed to be reported,and to grope for countermeasure to lessen the rate of nosocomial infection cases in disguise.METHODS The clinical data of the inpatients who were getting treatments in Oct 2004 and in Oct 2005 in the hospital were reviewed and analyzed.RESULTS The understanding and the recognition of nosocomial infection,the standards for judgement,the quatification of the medical workers,the medical cost and economic benefit ratio were all the causes that prevented nosocomial infection cases from being reported.CONCLUSIONS Propagandize the nosocomial infection management to make our medical workers attach importance to it,implement an objective obligation,constitute a hortative system,to exert the director's function and the workers′ enthusiasm,and choose high qualified workers to take charge in the nosocomial infection management,thus can prevent nosocomial cases from being reported.
Résumé
OBJECTIVE To search the methods of decreasing the missing report of nosocomial infection cases with a prospective monitoring method.METHODS To summarize the methods and measures that had been adopted for ten years.RESULTS There were four important means to decrease the missing report of nosocomial infection cases with a prospective monitoring method.The measures included combining prospective monitoring method and(retrospective) monitoring method at the beginning of taking prospective monitoring method,taking the right(methods),devising careful and precise researching procedure,reinforcing to propagandize and educate the(knowledge) of nosocomial infection to enhance the understanding of medical personnel to control nosocomial(infection),and analyzing and feedbacking the data of nosocomial infection with a prospective monitoring method.CONCLUSIONS It is necessary to develop the prospective monitoring method of investigating nosocomial(infection) as perfectly as possible.It can not only decrease the missing report of nosocomial infection with(prospective)(monitoring) method,but also effectively clue on trend of outbreak and epidemic of nosocomial infection.
Résumé
OBJECTIVE To ascertain the causes of unreported hospital infection in our hospital and apply countermeasures. METHODS To adopt investigation way to review and analyze 34 694 hospital files in our hospital from Aug 2002 to Jul 2004. RESULTS From them 1164 cases had experienced hospital infection,264 were unreported,the monthly unreported rate decreased from 52.50% to 0;the yearly unreported rate decreased from 36.17% to 10.67%. CONCLUSIONS The unreported reason is because the relevant staff lack infection knowledge,the control and supporting system isn′t so efficient.So the key to reduce the missing report rate is to enhance the awareness of the hospital infection control among the staff in hospital,to strengthen communication and cooperation,and to implement the administrative regulation.
Résumé
OBJECTIVE To investigate the different methods to calculate the rate of missing report on nosocomial infections.METHODS We had two methods to define the case of nosocomial infections,one was that the cases(infected) during the month we investigated,the other was that patients infected during the in hospital time.Then we got two different rates and "actually" nosocomial infection cases and compare the difference of the two results.(RESULTS) It was significant difference between these two results(P
