Objective To broaden the current understanding of the usage willingness about artificial intelligence (AI) robots and relevant influence factors for elderly patients. Methods The elderly patients in the inpatient ward, outpatient department and physical examination of the Department of Geriatrics, West China Hospital of Sichuan University were selected by convenient sampling for investigation between February and April 2020, to explore the willingness of elderly patients to use AI robots and related influencing factors. Results A total of 446 elderly patients were included. There were 244 males and 202 females. The willingness to use AI robots was (14.40±3.62) points. There were statistically significant differences among the elderly patients with different ages, marital status, living conditions, educational level, current health status, current vision status, current hearing status, self-care ability and family support in their willingness to use AI robots (P<0.05). Multiple linear regression analysis showed that age, education level and family support were the influencing factors of use intention (P<0.05). Among the elderly patients, 60.76% had heard of AI robots, but only 28.03% knew the medical application of AI robots, and only 13.90% had used AI robot services. Most elderly patients (>60%) thought that some adverse factors may reduce their usage willingness, like “the price is too expensive” and “the use is complex, or I don’t know how to use”. Conclusions Elderly patients’ cognition of AI robots is still at a low level, and their willingness to use AI robots is mainly affected by age, education level and family support. It is suggested to consider the personalized needs of the elderly in terms of different ages, education levels and family support, and promote the cheap and user-friendly AI robots, so as to improve the use of AI robots by elderly patients.
ObjectivesTo investigate Chinese health practitioners’ usage and demand for clinical practice guidelines in general so as to improve the development and implementation of guidelines.MethodsWe conducted a cross-sectional questionnaire survey that covered health practitioners from different levels of medical institutions in 17 provinces in China. Attitudes, adherence, usage barriers and demands for clinical practice guidelines were investigated.ResultsA total of 953 health practitioners were involved in the survey in which 931 completed the questionnaires. Respondents generally held positive attitudes toward guidelines and agreed that they improved quality of care and standardized diagnosis and treatment. More than 80% of the respondents reported a fine adherence to guidelines. The most reported barriers to follow the guidelines were " several guidelines are competing” and " lack of facilities and medical resources”. Most respondents agreed that it was necessary to establish a national guideline database, appraise implementation effect of guidelines, develop evaluation tools for guidelines that are applicable for Chinese clinical practice, and provide guidelines training.ConclusionsThis study finds favorable attitudes and fine adherence towards clinical guidelines in general in China. However, internal barriers, such as authority of guidelines, and external barriers, such as supplying system and patients’ preference, can affect guideline dissemination and implementation. It is suggested that establishing a national guidelines database, developing evaluation tools for guidelines that fit for Chinese clinical practice, and provision of guideline training, would facilitate the use of guidelines.
Objective To investigate the utilization of platinum drugs in 21 hospitals of Chengdu from 2011 to 2014. Methods The utilization information of platinum drugs in 21 hospitals of Chengdu from 2011 to 2014 was extracted, and the dosage form of drugs, consumption sum, frequency of drug use (DDDs), defined daily cost (DDC), and drug sequence ratio (B/A) were analyzed statistically. Results From 2011 to 2014, the total consumption sums and DDDs of platinum drugs were increased year by year. The consumption sums of oxaliplatin were the highest, and the consumption sums of carboplatin were increased year by year. Oxaliplatin, nedaplatin, and lobaplatin were ranked first, second and fifth respectively in all the four consecutive years; the total DDDs of patinum drugs from 2011 to 2014 showed a trend of increase, DDDs of cisplatin were always ranked first, followed by oxaliplatin; DDC and sorting of platinum drugs were relatively stable, and B/A values of carboplatin and cisplatin were close to 1.00. Conclusion The utilization of platinum drugs in 21 hospitals of Chengdu is in accordance with the principle of safety, effectiveness, economy and convenience.
ObjectivesTo systematically review the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM and WanFang Data databases were electronically searched to collect clinical studies on the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy from January 1990 to September 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.3 software and Stata 15.0 software.ResultsA total of 8 retrospective cohort studies and 1 randomized controlled trial involving 60 136 subjects were included. The results of the meta-analysis showed that: there was no difference in the post-operational infection rate among patients with and without antimicrobial prophylaxis for arthroscopies (OR=0.51, 95%CI 0.25 to 1.04, P=0.06). For knee arthroscopies, the post-operational infection rate had no difference between patients with and without antimicrobial prophylaxis (OR=0.89, 95% CI 0.65 to 1.23, P=0.48). However, for shoulder arthroscopies, the post-operational infection rate in the antimicrobial prophylaxis group was significantly lower than that in the group without the antimicrobial prophylaxis(OR=0.18, 95%CI 0.08 to 0.37, P<0.000 01).ConclusionsCurrent evidence shows that there is no association between preoperative antimicrobial prophylaxis and a decreased infection rate for knee arthroscopies. Antimicrobial prophylaxis appears to lead to fewer infections after shoulder arthroscopies. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To investigate the difference of anticoagulant efficacy of heparin and citric acid during continuous renal replacement therapy (CRRT) in patients with severe acute pancreatitis, and analyze their effects of on filter life span, length of hospital stay and mortality. Methods Patients with severe acute pancreatitis in Intensive Care Unit of the First Affiliated Hospital of Hebei North University between January 2018 and July 2022 were retrospectively enrolled, and they were divided into heparin group (control group) and citric acid group (research group) according to anticoagulation methods. The differences of anticoagulant catheter blockage during CRRT, filter life span, length of hospital stay, and 90-day mortality between the two groups were analyzed. Results A total of 108 patients were enrolled, including 56 in the research group and 52 in the control group. In pre-CRRT treatment, the balance value of fluid intake and outflow in the research group was significantly lower than that in the control group (P<0.05). The 108 patients received 217 times of CRRT treatment totally, with a median length of treatment of 63 h (range 44-87 h). The severity of catheter blockage in the research group was lower than that in the control group (P=0.003). The filter life span was longer in the research group than that in the control group [42.5 vs. 29.0 h; hazard ratio=1.83, 95% confidence interval (1.23, 2.73), P<0.001]; in the comparison of 90-day mortality, there was no significant difference between the two groups (P>0.05). The mean use of filters in the research group was less than that in the control group (1.93±0.09 vs. 2.17±0.14, P<0.001). The downtime of CRRT due to filter life in the research group was obviously shorter than that in the control group [120 (0, 720) vs. 300 (0, 890) min, P=0.029], while the duration of CRRT in the research group was remarkably better than that in the control group [10.6 (4.9, 27.7) vs. 8.1 (3.6, 25.0) d, P=0.024], and the risk of filter replacement due to special conditons in the research group was lower than that in the control group (46.4% vs. 65.4%, P=0.048). There was no statistically significant difference in the length of intensive care unit hospitalization or total hospitalization between the two groups (P>0.05). Conclusion Both heparin and citric acid could assist the treatment of CRRT, while citric acid might be apt to improve local coagulation and systemic inflammatory response.
ObjectiveTo explore the personalistic characteristics of patients with migraine and medication-overuse headache (MOH), and to provide scientific evidence for mental treatment of these patients. MethodsThe subjects were divided into three groups:migraine group, MOH group, and health group.Patients with migraine or MOH, admitted to the Deyang People's Hospital from March 2012 to March 2014, were selected in this study.In addition, healthy volunteers were selected as controls at the same time.Data were collected through the Minnesota multiphasic personality inventory computer testing software, and differences of personalistic characteristics were compared among patients with migraine, MOH and controls. ResultsPatients with migraine and MOH had mental problems and the occurrence rate of psychological problems of MOH patients was significantly higher than that of migraine patients (χ2=6.055, P=0.014).Migraine patients showed higher scores of hypochondriasis, depression, hysteria, psychasthenia, hypomania than controls (P < 0.01).Compared with migraine patients, the scales of hypochondriasis, depression, hysteria, paranoia, schizophrenia were higher in MOH patients (P < 0.01). ConclusionsPatients with migraine and MOH have personalistic and psychological problems.Early screening of personalistic characteristics and mental interventions may improve the clinical outcome of patients with migraine or MOH.
ObjectiveTo explore the risk factors for surgical patients associated with postoperative nosocomial infection through monitoring the infection conditions of the patients, in order to provide a scientific basis for the development of hospital infection control measures in a second-grade class-A hospital in Chengdu City. MethodsWe conducted the survey with cluster sampling as the sampling method and the uniform questionnaire in the departments of orthopedic, neural and thoracic surgery from July 2011 to June 2012. The main parameters we observed were the patients'general and surgical conditions, antibiotics usage and hospital infection situation. Data were analyzed using the National Nosocomial Infection Surveillance Network software and chi-square test of single factors. ResultsIn this survey, we monitored 50 cases of postoperative hospital infection. The infection rate was 7.73% and the highest infection rate was in the Neurosurgery Department. The main site of infection was lower respiratory tract, followed by surgical site. The different usage time of antimicrobial drug in perioperative period resulted in different infection rates, and the difference was statistically significant (χ2=601.50, P<0.005). The rate of adjusted postoperative hospital infection was higher than pre-adjusted rate except that of the neurosurgery doctor 4. The risk factors associated with hospital postoperative infection in our hospital were:patients'conditions including underlying disease, emergency surgery, type of anesthesia, operative duration, hospital stay and postoperative drainage. Most of the hospital infection cases were caused by bacteria of the gram-negative bacilli, and the major pathogens were Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii in our hospital. ConclusionThe hospital should particularly strengthen the prevention and control of hospital infection in patients after neurosurgical operations. For patients with basic diseases, we should actively improve the patients'physical conditions before operation and control the primary lesion. Targeted control measures should be taken for different factors related to surgery. Reasonable selection of antimicrobial agents should be based on the epidemic strains in our hospital.
ObjectiveTo investigate the effects of antimicrobial management program on inpatients outcomes and antimicrobial resistance among clinical isolates in a large-scaled university hospital.MethodsThe antibiotics use density (AUD) and antimicrobial resistance rate of multi-drug resistant bacteria before (from January 2009 to December 2010) and after (from January 2012 to December 2016) the intervention of antimicrobial management program in a large-scaled university hospital (4 300 beds) were calculated and compared, and the correlations of AUD with average length of hospital stay and mortality rate were analyzed.ResultsThe AUD was significantly decreased after intervention (P<0.001). The resistance rate of Staphylococcus aureus to oxacillin decreased (P<0.001). Among Gram-negative bacteria, the resistance rates to carbapenems in Acinetobacter baumannii (P<0.001) and Klebsiella pneumoniae increased (P=0.011). AUD was not correlated with the average length of hospital stay (P=0.644), while positively correlated with the in-hospital mortality rate (r=0.932, P=0.001).ConclusionsThe implementation of antimicrobial management program can significantly reduce the antimicrobial use and do not worsen patient outcomes in the hospital. The impact of the program on resistance varies significantly depending on both the bacterium and the agent, and carbapenem-non-susceptible Gram-negative bacilli emerges as a major threat. It is still necessary to combine other infection control measures.
