Objective To realize the current situation of prevention and control of catheter-associated urinary tract infection (CAUTI)since the development of healthcare-associated infection(HAI)management in China in the re-cent 30 years.Methods Random cluster sampling was used to select 165 secondary and tertiary hospitals in 13 provinces and cities in China,questionnaires were filled in,the content included time,scope,method,data feed-back,and incidence of CAUTI monitoring.Results Of 165 hospitals,92.12% (152/165)have implemented targe-ted monitoring,the implementation rate in tertiary hospitals was higher than secondary hospitals (98.08% [102/104]vs 81.97%[50/61],χ2 =13.748,P <0.001).Most hospitals (82.24%[125/152])only implemented monito-ring in intensive care units(ICUs)or partial ICUs.HAI management professionals,HAI control doctors and nurses in 69.08%(105/152)of hospitals jointly took responsibility for CAUTI monitoring.95.39% (145/152)of hospitals diagnosed CAUTI by combination of clinical manifestations and laboratory examination results.98.68%(150/152) of hospitals have gradually implemented intervention measures,such as strictly mastering the indications of urinary indwelling catheters,hand hygiene of health care workers,non-frequent change of urinary indwelling catheters,and necessity for daily assessment of catheterization.75.66% (115/152)of hospitals conducted feedback of monitored results to the whole hospital.Incidences of CAUTI in pre-2010,2010,and 2015 were 3.10‰,4.72‰,and 1.89‰respectively.Conclusion In the recent 30 years,monitoring on CAUTI in China has obtained achievement,CAUTI monitoring is gradually standardized and scientific,but the development at all levels of medical institutions is still imbalance,which needs to be improved further.

Objective To understand the status of awareness of hand hygiene(HH)knowledge and compliance among health care workers (HCWs)in China,and provide scientific basis for further improvement of HH practice. Methods A multi-centre retrospective survey on awareness of HH knowledge and compliance was conducted in 200 nationwide hospitals in 2015.Results The awareness rates of HH methods and HH indications among HCWs were 86.5% and 82.5% respectively;cleaning staff had the lowest awareness rate of HH indications(69.9%),followed by the other interns and advanced-study students (70.2%),as well as medical technicians (79.8%);attendants had the lowest awareness rate of HH methods(76.9%),followed by advanced-study students and interns(81.0%),and cleaning staff (82.4%);HH knowledge awareness rate among HCWs in secondary hospitals was lower than tertia-ry hospitals,and the district-level hospitals had the lowest awareness rate of HH.HH compliance rate and correct rate were 70.1% and 74.9% respectively;the interns and advanced-study students were at a low level of compliance and correct rates (61.4% and 60.9% respectively);the municipal hospitals had the lowest compliance and correct rates,non-teaching hospitals were lower than teaching hospitals.Conclusion HH in primary hospitals is weak,HH of interns,advanced-study students,as well as attendants and cleaning staffs are not enough,HH management should be strengthened,awareness and compliance of HH should be improved.

Objective To explore the direct economic loss caused by healthcare-associated infection(HAI)in general hospitals in China.Methods 68 hospitals were selected,a retrospective 1:1 matched survey was conducted to compare the direct medical cost in patients with and without HAI between January 1,2015 and December 31,2015. Results A total of 2 123 pairs of patients with and without HAI were included in the survey.The average cost of hospitalization in HAI and non-HAI groups were ￥25 845.30 and ￥12 006.14 respectively,￥13 839.16 on average was increased due to HAI.The average economic loss in provincial and ministerial levels of hospitals were￥21 409.83.The average economic loss in different regional hospitals were ￥9 725.42-￥18 909.59,and north China ranked the first.Economic loss caused by bloodstream infection and lower respiratory tract infection were more than other sites,which were ￥23 190.09 and ￥18 194.50 respectively.Conclusion HAI resulted in considerable direct economic loss.Prevention and control of HAI,especially bloodstream infection and lower respiratory tract infection should be paid more attention.

Objective To understand the current situation of occupational exposure and protection among health care workers (HCWs ), and provide evidence for formulating preventive measures of occupational exposure. Methods From April 6,2016 to May 6,2016,questionnaire surveys were conducted in 158 different levels of hos-pitals in 13 provinces in China,occupational exposure,protection management,and monitoring of occupational expo-sure in the first year,2010,and 2015 was surveyed by cluster random sampling method.Results Occupational ex-posure in 81.65% (129/158)of hospitals was responsible by healthcare-associated infection management depart-ments;98.73%(156/158)of hospitals set up the relevant rules and regulations;77.22%(122/158)of hospitals had missing report of occupational exposure.A total of 11 116 times of occupational exposure occurred (1 542 cases in the first year,2 474 in 2010,and 7 100 in 2015).Of various types of occupational exposure,sharp injury accounted for 96.76%;among HCWs sustained occupational exposure,nursing staff accounted for 53.90%;the major de-partment that HCWs who sustained occupational exposure were general wards,operating rooms,and intensive care units;the main medical appliances related to occupational exposure were syringes,scalp needles,and surgical suture needles;high-risk behavior causing occupational exposure were intravenous injection,putting needles into the sharp con-tainers,and surgical suturing;among occupational exposure sources,HBV accounted for 58.69%.Conclusion HCWs in China face a high risk of occupational exposure,occurrence of occupational exposure should be reduced through gov-ernment legislation,application of safety appliances,standardizing behavior of HCWs,proper using of personal pro-tective equipment,strengthening education and training of HCWs,and establishing a sound occupational exposure report,evaluation and follow-up system.

Objective To summarize the effectiveness in monitoring activities for healthcare-associated infection (HAI)in China in the past 30 years,explore the changing trend in HAI monitoring,find a new model for the moni-toring of HAI in China.Methods A total of 194 comprehensive hospitals and military hospitals in 13 provinces (au-tonomous regions,municipalities)were selected,questionnaire survey was adopted to investigate the situation of HAI monitoring.Results Of 194 hospitals,184 (94.85%)had available data after being checked,incidence of HAI in secondary and tertiary hospitals were 0.78% and 1.58% respectively,difference was significant (P <0.01).Monitoring was divided into two stages,cumulative percentage of each monitoring activity before 2006 and during 2006-2016 were respectively as follows:environmental hygiene were 73.91% and 100.00%,disinfection ef-ficacy 69.57% and 97.28%,overall comprehensive monitoring 64.67% and 98.91%,surgical site infection(SSI) 13.04% and 94.57%,ICU HAI 4.89% and 87.50%,neonatal HAI 1.75% and 60.82%,multidrug-resistant or-ganisms(MDROs)5.43% and 95.65%,hand hygiene compliance 2.17% and 93.48%,antimicrobial agents 15.22% and 87.50%.The reporting rate of HAI outbreak in tertiary hospitals was higher than secondary hospitals (33.33% [n=37]vs 16.44%[n=12],P =0.01).Conclusion The monitoring of HAI in China starts late,but develops rapidly,defects still exist in HAI monitoring system,reporting rate of HAI cases is still high,reporting rate of HAI outbreak is low.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
