ObjectiveTo evaluate the application of Delone & Mclean (D&M) model in foreign health information technology (HIT), summarize each variable with its emphasis on HIT, in order to provide a reference and theoretical guidance for the evaluation HIT in clinical practice in China. MethodsOvid-medline, Embase, PubMed, Engineering Village, Web of Science, EBSCO, Wanfang Data, Chinese National Knowledge Infrastructure and VIP databases were searched from January 1993 to April 2015. Included articles focused on studies about D&M model applied in HIT. Two reviewers independently screened titles and abstracts to determine inclusion status. The process was completed by Endnote X6. ResultsFinally, there were 14 eligible full-text papers. In the evaluation, Europe and US accounted for 64.29% in the leading place, Australasia ranked second with 28.57%, and Asia was at last with 7.1%. So it is significant to draw lessons from foreign research. For the methods of data collection, survey was widely used (91.7%). The system quality, information quality and service quality had a significant positive correlation with users' satisfaction and net benefit. ConclusionD&M Model is a good tool to assess HIT.
ObjectivesTo systematically review the efficacy of problem-based learning (PBL) model in clinical oncology teaching.MethodsPubMed, EMbase, CNKI, WanFang Data, CBM databases were electronically searched to collect randomized controlled trials (RCTs) of PBL model used in clinical oncology teaching in China from January, 2000 to March, 2019. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 and Stata 12.0 software.ResultsA total of 29 RCTs involving 2 238 subjects were included. The results of meta-analysis showed that: PBL model in clinical oncology teaching was superior to traditional lecture-based learning (LBL) model on the total score (MD=6.50, 95%CI 4.44 to 8.55, P<0.000 01), theoretical knowledge score (MD=4.58, 95%CI 3.38 to 5.78, P<0.000 01), case analysis score (MD=4.26, 95%CI 3.38 to 5.78, P<0.000 01), skill operation score (MD=6.10, 95%CI 4.77 to 7.43, P<0.000 01), overall course satisfaction (RR=1.74, 95%CI 1.34 to 2.27, P<0.000 01), increased learning interest (RR=1.52, 95%CI 1.28 to 1.81, P<0.000 1), improved teamwork cooperation (RR=1.67, 95%CI 1.39 to 2.01, P=0.002), and improved self-study ability (RR=1.51, 95%CI 1.20 to 1.90, P<0.000 1), the differences were statistically significant.ConclusionsCurrent evidence shows that the PBL model can improve clinical teaching effect of oncology and learning satisfaction. Due to limited quality and quantity of the included studies accumulated, more high quality studies are required to verify above conclusion.
In order to provide a reference and theoretical guidance of the evaluation of electronic medical record (EMR) and establishment of evaluation system in China, we applied a bibliometric analysis to assess the application of methodologies used at home and abroad, as well as to summarize the advantages and disadvantages of them. We systematically searched international medical databases of Ovid-MEDLINE, EBSCOhost, EI, EMBASE, PubMed, IEEE, and China's medical databases of CBM and CNKI between Jan.1997 and Dec.2012. We also reviewed the reference lists of articles for relevant articles. We selected some qualified papers according to the pre-established inclusion and exclusion criteria, and did information extraction and analysis to the papers. Eventually, 1 736 papers were obtained from online database and other 16 articles from manual retrieval. Thirty-five articles met the inclusion and exclusion criteria and were retrieved and assessed. In the evaluation of EMR, US counted for 54.28% in the leading place, and Canada and Japan stood side by side and ranked second with 8.58%, respectively. For the application of evaluation methodology, Information System Success Model, Technology Acceptance Model (TAM), Innovation Diffusion Model and Cost-Benefit Access Model were widely applied with 25%, 20%, 12.5% and 10%, respectively. In this paper, we summarize our study on the application of methodologies of EMR evaluation, which can provide a reference to EMR evaluation in China.
ObjectiveTo investigate and compare the clinical characteristics of chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap syndrome (ACOS). MethodsA case-control study was conducted in 139 patients with COPD who admitted between March 2013 and September 2013. The patients were divided into a COPD-only group and an ACOS group. Clinical data were collected and compared between two groups. ResultsOf all 139 patients, 93 patients were diagnosed with COPD only (66.9%) and 46 patients were diagnosed with ACOS (33.1%). Compared with the COPD-only group, the ACOS group had a lower ratio of exposure to cigarette smoking (80.4% vs. 93.5%), but high possibility of a history of asthma (89.1% vs. 4.3%), allergies (60.9% vs. 9.6%) and airway hyperreactivity (80.4% vs. 6.5%) (P < 0.05). In clinical symptoms, the ACOS group had a higher ratio of breathless as the first complaint of symptom (26.1% vs. 8.6%) and dry and moist rales in lung by auscultation (67.4% vs. 31.2%) (P < 0.05). In laboratory examination, the ACOS group had increased levels of peripheral blood eosinophils and IgE than those of the COPD-only group (21.7% vs. 5.4%, 18.3% vs. 4.3%, P < 0.05). In treatment, the ACOS group was more likely to use systemic glucocorticoid (58.7% vs. 24.7%) and be treated with higher dosage of glucocorticoid (80 mg, P < 0.05). ConclusionsACOS and COPD-only are two subtypes of COPD. Compared with COPD-only patients, ACOS patients might be more likely to be breathless and have dry and moist rales in clinical symptoms, more likely to have increased levels of peripheral blood eosinophils and IgE in blood test, and more inclined to receive systemic glucocorticoid treatment.
Objective To establish a model for prognosis analysis of severe community-acquired pneumonia in order to find the independent risk factors for mortality. Methods The data of 88 patients with severe community-acquired pneumonia enrolled from 533 community-acquired pneumonia patients in Fujian Provincial Hospital from April 2012 to December 2015 were analyzed, they were divided into a survival group and a death group according to prognosis. The clinical materials of basic data of the population, clinical manifestation, treatment and prognosis and pulmonary severity indexes were collected. Then univariate analysis was used to screen risk factors of death before logistic multivaritae regression was applied to explore independent risk factors. Results The different pathogen groups including viral, bacterial, mixed infection, negative and other groups were compared and no differences were found in mortality (all P>0.05). Univariate analysis revealed antibiotics treatment before admission, higher APACHEⅡ score, higher Chalison's score, septicopyemia, and higher level of procalcitonin, blood urea nitrogen (BUN), blood glucose, lactate could increase death risk for the patients. While antiviral treatment and no invasive mechanical ventilation were determined as protective factors. Logistic multivaritae regression showed three factors including higher lactate and higher serum BUN and higher heart rates were independent death risk factors [OR values were 4.704 (95%CI 0.966-22.907), 1.264 (95%CI 0.994-1.606), and 1.081 (95%CI 1.003-1.165), respectively]. Whereas no invasive mechanical ventilation was protective factor (OR=0.033, 95%CI 0.001-0.764). Conclusion The patients with higher lactate and BUN, higher heart rate and accepting invasive mechanical ventilation have poor prognosis.
