Prognostic accuracy of five common scoring systems for mortality in elderly patients with sepsis / 中国医师杂志

Objective:To assess the prognostic accuracy of five scoring systems for mortality in elderly patients (≥80 years old) with sepsis.Methods:A retrospective study was conducted on elderly patients with sepsis (≥80 years old, meeting Sepsis 3.0 diagnostic criteria) in Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ). The participants were divided into survival and death group according to the 28-day mortality. The baseline data of patients was collected based on the peak of vital signs and laboratory test results within 24 hours after admission to intensive care unit (ICU). Systemic Inflammatory Response Syndrome (SIRS) score, quick Sequential Organ Failure Assessment (qSOFA), Sequential Organ Failure Assessment (SOFA), National Early Warning Score (NEWS) and Oxford Acute Severity of Illness Score (OASIS) were calculated and prognosis was recorded. The accuracy of the above scoring systems in predicting 28-day mortality was calculated, the receiver operating characteristic (ROC) curve was plotted, and the area under the ROC curve (AUC) was calculated and compared.Results:A total of 42 037 hospital records were screened, and 956 sepsis patients (456 males, 47.70%) who were aged ≥80 years and met the Sepsis 3.0 diagnostic criteria within 24 hours of admission to ICU were included. There were 696 patients (72.8%) in the survival group and 260 patients (27.2%) in the death group. There were no significant difference in age, gender, Charlson Comorbidity Index, length of stay before admission to ICU and length of stay in ICU between 2 groups (all P>0.05). The proportion of patients receiving mechanical ventilation and septic shock in the death group were higher comparing with those in the survival group (both P<0.001), and the total length of hospital stay in the survival group was longer than that in the death group ( P<0.001). The proportion of SOFA score≥7, qSOFA score≥2, SIRS score≥2, NEWS score≥8, OASIS score≥42 in the death group was higher than that in the survival group (all P<0.05). The AUC of qSOFA, SOFA, SIRS, NEWS and OASIS in predicting the mortality of elderly sepsis patients were 0.587 (95% CI: 0.556-0.617), 0.694 (95% CI: 0.655-0.732), 0.591 (95% CI: 0.555-0.627), 0.684 (95% CI: 0.646-0.721) and 0.718 (95% CI: 0.681-0.755), respectively. Conclusions:OASIS was superior than qSOFA, SOFA, SIRS and NEWS scores in predicting the mortality of elderly patients with sepsis, but the prognostic accuracy of all above scoring systems for elderly patients with sepsis was insufficient.

The value of systemic immune inflammation index in predicting the risk of hospital death in critically ill patients / 中华急诊医学杂志

Objective:To explore the predictive value of systemic immune inflammation index (SII) for the risk of hospital death in critically ill patients.Methods:The basic information and clinical data of critically ill patients were extracted from the Medical Information Mart for Intensive Care database-Ⅳ (MIMIC-IV) database, including demographic data, vital signs, blood routine, Logistic organ dysfunction score (Lods), Oxford acute severity of illness score (Oasis), simplified acute physiology score (Saps-Ⅱ), acute physiology score Ⅲ (APS-Ⅲ), sequential organ failure score (SOFA) and outcome. The main outcome was hospital death, and the secondary outcomes were length of hospital stay, continuous renal replacement therapy (CRRT), invasive ventilation and 1-year mortality. Patients were divided into two groups according to in-hospital death, and the differences between the groups were compared. According to the SII tripartite for inter-group comparison, the patients were further divided into three groups for comparison, and Logistic regression model was used to analyze the odd ratio ( OR) of the three groups. Results:A total of 32 450 critically ill patients were included in the study, of which 3765 died in hospital, with a mortality rate of 11.6%. ① Compared with the survival group, the SII in the death group were significantly higher ( P < 0.05). ② The mortality for the SII tripartite grouping (<817; 817~2 151; >2 151) were 8.4%, 10.2% and 16.3%, respectively, and the differences between groups were statistically significant. ③ Further, Logistic regression model analysis showed that the risk of death increased gradually with the increase of groups (the first group was the reference group, OR of the second group was 1.38, 95% CI 1.24-1.54, and OR of the third group was 2.03, 95% CI 1.83-2.24 ( P < 0.05). Conclusions:SII has a certain value in predicting hospital death in critically ill patients. It is easy to obtain and can be used for risk stratification of critically ill patients.

Differences in microbiology and bacterial susceptibility between alcohol abuse and no alcohol abuse in intensive care unit patients / 中国综合临床

Objective:To investigate the differences in microbiological examination results between alcohol abuse and no alcohol abuse in adult ICU patients and the association between alcohol abuse and these differences.Methods:The adult patients with microbiological examination results were selected from the MIMIC-Ⅲ database and divided into two groups according to whether they had alcohol abuse. The two groups were matched by propensity score, and the similarities and differences in microbiological examination results were evaluated between the two groups after matching. The measurement data of non normal distribution were expressed by M ( Q1, Q3). Wilcoxon rank sum test was used for the comparison of the two groups, and the comparison of counting data was used χ 2 test or Fisher exact probability method. Results:After matching, the alcohol abuse patients were more likely to use mechanical ventilation (47.06% (1 379/2 930) vs. 52.66% (1 543/2 930), χ 2=18.14, P<0.001), had a higher positive rate in sputum samples (44.30% (400/903) vs. 49.41% (501/1 014), χ 2=4.81, P=0.028) and had a lower positive rate in other samples (26.85% (653/2 432) vs. 21.67% (541/2 496), χ 2=17.69, P<0.001). In blood samples, the percentage of Gram-negative bacteria was lower in the alcohol abuse group (26.87% (126/469) vs. 17.25% (74/429), χ 2=11.42, P<0.001), while the percentage of Gram-positive bacteria was higher (78.46% (368/469) vs. 86.01% (369/429), χ 2=8.17, P=0.004). The percentage of patients with Pseudomonas aeruginosa (3.75% (110/2 930) vs. 2.08% (61/2 930), χ 2=13.88, P<0.001) and Enterococcus sp. (8.19% (240/2 930) vs. 6.45% (189/2 930), χ 2=6.29, P=0.012) was lower in the alcohol abuse group. However, there was a higher percentage of patients with methicillin-resistant Staphylococcus aureus (2.32% (68/2 930) vs. 3.28% (96/2 930), χ 2=4.57, P=0.032) and Haemophilus influenzae (1.30% (38/2 930) vs. 2.01% (59/2930), χ 2=4.19, P=0.041) in the alcohol abuse group. For Staphylococcus aureus (61.10% (322/527) and 52.66% (267/507), χ 2=7.16, P=0.007) and Enterococcus sp. (75.83% (160/211) and 63.64% (56/88), χ 2=4.02, P=0.045), the alcohol abuse group had a lower resistance to levofloxacin; for Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae, the alcohol abuse group had a lower resistance to cephalosporins (all P<0.05). Conclusions:In adult ICU, alcohol abuse might increase the risks of using mechanical ventilation, and patients with alcohol abuse might be more prone to have respiratory tract infections. Alcohol abuse patients with blood infections were less likely to be infected with Gram-negative bacteria, but had a higher probability of Gram-positive bacteria infection. What is more, Alcohol abuse might increase the risks of infections with Haemophilus influenzae and methicillin-resistant Staphylococcus aureus. In alcohol abuse patients, the infection of Staphylococcus aureus, Enterococcus sp., Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae was less resistant to many antibiotics than that in no alcohol abuse patients.

The Significance of New Chapter of Traditional Medicine in the Eleventh Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-11) / 日本東洋医学雑誌

A commemorative lecture meeting on the inclusion of a new chapter of traditional medicine in ICD­-11 was held in Tokyo in February 2020. The head of the Collaborating Centre for WHO­-FIC in Japan explained the process of the project, which started in 2006 to increase WHO's data collection from developing countries and expressed gratitude to the concerned persons who made efforts to obtain consensus with China and Korea. WHO promoted integrated coding between traditional medicine and Western medicine. In the field of acu­puncture, meridian and collateral patterns proposed by Japan were adopted and research activities have begun. In the field of Kampo medicine, the prescription content is often used in a fixed form as a representative for­mula pattern in Japan, so clinically high­-level research will be possible under this new classification. In the field of medical information, it has been pointed out that there are high hurdles for medical information man­agers to understand traditional medicine. It is expected that the progress of mutual understanding of both medi­cines. From now on, activities in research, translation, education and dissemination of this new classification should be promoted.

Effect of high-flow nasal cannula oxygen on patients with chronic obstructive pulmonary disease and mild hypercapnia: a retrospective cohort study based on the Medical Information Mart for Intensive Care-Ⅳ database / 中华危重病急救医学

Objective:To observe the effect of high-flow nasal cannula oxygen therapy (HFNC) in patients with chronic obstructive pulmonary disease (COPD) and mild hypercapnia, and to evaluate the early predictive ability of physiological parameters in these patients.Methods:A retrospective cohort study was conducted based on Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ) updated in September 2020 and the data of adult patients with COPD and mild hypercapnia [45 mmHg (1 mmHg = 0.133 kPa) < arterial partial pressure of carbon dioxide (PaCO 2)≤ 60 mmHg] from 2008 to 2019 were collected. These patients were assigned to the HFNC group or non-invasive ventilation (NIV) group according to whether they received HFNC or NIV. Baseline data such as gender, age, body mass index (BMI), simplified acute physiology scoreⅡ (SAPSⅡ), Charlson comorbidity index (CCI) and physiological parameters were collected. A propensity score matching was conducted according to the baseline data of the HFNC group patients. The 48-hour and 28-day intubation rates, 28-day mortality, length of intensive care unit (ICU) stay, the length of hospital stay, and the changes in physiological parameters within 48 hours after treatment were compared between the two groups. The receiver operating characteristic curve (ROC curve) was drawn and the ratio of heart rate over pulse oxygen saturation (HR/SpO 2) and ROX index [SpO 2 / (inhaled oxygen concentration, FiO 2×respiratory rate, RR)] were analyzed to predict the 24-hour and 48-hour intubation rates. Results:A total of 524 520 inpatient records were screened and 153 patients were included, while 37 patients in the HFNC group and 116 patients in NIV group. There were 31 patients in the HFNC group and 84 patients in the NIV group remained after propensity score matching according to the baseline data. There were no significant differences in the baseline data of gender, age, BMI, SAPSⅡ, CCI score, physiological parameters and prognosis data except the length of ICU stay. The length of ICU stay in HFNC group was significant longer than that of the NIV group [days: 4.6 (3.1, 10.0) vs. 3.1 (1.6, 5.8), P < 0.05]. HR and RR at 40- 48 hours were significantly lower than those at 0-8 hours after treatment only in the HFNC group [HR (bpm): 84.1±12.2 vs. 91.1±16.4, RR (times/min): 19.8±4.9 vs. 21.6±4.1, both P < 0.05]. Both in the HFNC group and NIV group the pH increased (7.42±0.08 vs. 7.36±0.05 and 7.41±0.06 vs. 7.36±0.05, both P < 0.05) and PaCO 2 decreased significantly [mmHg: 46.3 (39.5, 51.0) vs. 49.8 (45.5, 54.0) and 46.0 (40.5, 51.5) vs. 49.5 (45.5, 55.3), both P < 0.05]. The HR, PaO 2 were higher in the HFNC group than those in the HFNC group at 40-48 hours after treatment [HR (bpm): 91.1±15.4 vs. 84.1±12.2, PaO 2 (mmHg): 99.5 (86.0, 132.3) vs. 85.8 (76.5, 118.0), both P < 0.05], PaO 2/FiO 2 were lower in the HFNC group than that in the HFNC group at 40-48 hours after treatment [mmHg: 223.8 (216.5, 285.0) vs. 278.0 (212.3, 306.0), P < 0.05]. Both HR/SpO 2 and ROX index at 4 hours after treatment had predictive value for 24-hour and 48-hour intubation in the HFNC group. The areas under ROC curve (AUC) of HR/SpO 2 at 4 hours after treatment in the HFNC group were larger than those of ROX index for predicting 24-hour and 48-hour intubation (24-hour: 0.649 vs. 0.574, 48-hour: 0.692 vs. 0.581, both P < 0.01); the 95% confidence interval (95% CI) of 4 hours HR/SpO 2 and for ROX index predicting 24 hours and 48 hours intubation were 0.497-0.780, 0.567-0.799, 0.450-0.694 and 0.454-0.716, respectively. The high sensitivity of HR/SpO 2 and ROX index in predicting 24-hour and 48-hour intubation were 84.6%, 92.9%, 88.2% and 94.4%, respectively, and the low specificity were 52.3%, 23.7%, 54.7% and 29.6%, respectively. Conclusions:HFNC can be used in COPD patients with mild hypercapnia, but it cannot replace NIV. The accuracy of ROX index at 4 hours after HFNC treatment in predicting intubation in COPD patients with mild hypercapnia is poor.

Early predictors of high flow oxygen treatment failure for post-operation patients with hypoxemia / 中华急诊医学杂志

Objective:To explore the early predictors of high flow oxygen treatment failure for post-operation patients with hypoxemia.Methods:The post-operation adult patients with hypoxemia (100 mmHg<PaO 2/FiO 2≤300 mmHg) received high flow nasal cannula (HFNC) oxygen were retrospectively screened in the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The patients were assigned to the treatment success or failure group according to whether receiving reintubation with 48 h after extubation. The risk factors of 48-h reintubation were screened and analyzed by extreme gradient boosting (XGBoost) algorithm. And the predictors were formulated according to the risk factors. The changes of predictors were collected from extubation to 48 h later. The predictors were compared at different time points after extubation between patients weaning successfully and failed with t test. The values at different time after extubation were also compared to the baseline data. The areas under the receiver operating characteristic (ROC) curve were calculated for 48-h reintubation prediction according to values at 4 h before and after extubation, which were compared with those of rapid shallow breathing index (RSBI) and ROX index. The RSBI was defined as the ratio of respiratory rate to tidal volume. The ROX index was defined as the ratio of SpO 2/FiO 2 to respiratory rate. Results:A total of 524 520 medical records were screened and 318 patients were included. There were 38 patients (11.95%) received reintubation within 48 h. According to the XGBoost model, the important features of 48-h reintubation were the duration before extubation, body mass index, simplified acute physiology scoring II, heart rate (HR), PaO 2, mean blood pressure, tidal volume, age, SpO 2 and respiratory rate. Thus HR/PaO 2 and HR/SpO 2 were formulated as predictors for 48-h reintubation according to the above features. The areas under the ROC of HR/PaO 2 and HR/SpO 2 were 0.640 and 0.617 for 48-h reintubation prediction according values at 4 h before extubation, which were larger than those of RSBI (0.537) and ROX index (0.539). According values at 4 h after extubation, the area under the ROC of HR/SpO 2 was 0.657, which was larger than that of ROX index (0.587). When the HR/SpO 2 reached 1.2 at 4 h after extubation, the specificity for 48-h reintubation was 92%. There was significant difference of HR/SpO 2 at 4 h after extubation between patients weaning successfully and failed (1.02 vs 0.92, P<0.05), and no significant difference of ROX index at the same time (8.14 vs 9.27, P>0.05). There were significant differences of HR/SpO 2 and ROX index at 8 to 12 h after extubation between the two groups (both P<0.05). Conclusions:HR/SpO 2 is more early and accurate in predicting HFNC failure than ROX index for post-operation patients with hypoxemia. However, both the predictors should be further evaluated.

Producción científica sobre la COVID-19 en revistas médicas cubanas a 90 días del inicio de la pandemia / Scientific production on COVID-19 in Cuban medical journals during the first 90 days after the start of the pandemic

RESUMEN Introducción: Desde la aparición del primer caso contagiado por el SARS-Cov-2, la pandemia ha experimentado un ascenso en el número de casos casi incontrolable. La producción científica juega un papel clave en la lucha por este necesario control y erradicación. El número de artículos que se produce diariamente desde los inicios sobrepasan los miles a nivel internacional y las editoriales y bases de datos han puesto su mayor esfuerzo para que estas contribuciones tengan la debida prioridad y visibilidad. Cuba no ha hecho menos en este esfuerzo. Objetivo: caracterizar la producción científica publicada en revistas médicas cubanas en los primeros noventa días de inicio de la pandemia en Cuba. Material y Métodos: se realizó un estudio descriptivo transversal donde se analizaron el 100 por ciento de las revistas médicas certificadas como científicas. Se definieron variables como tipología documental, afiliaciones institucionales y colaboración, temática, país y tiempo de publicación entre otros. Resultados: El 58 por ciento de los artículos publicados correspondió a revistas de universidades médicas. El 31,1 por ciento fue aportado por la revista Medisur de la Universidad de Ciencias Médicas de Cienfuegos. El 77,8 por ciento de los artículos son cubanos. El 22,6 por ciento fueron cartas al editor, seguidas de 20,8 por ciento correspondiente a artículos originales. Conclusiones: la producción científica nacional en revistas médicas cubanas en el período estudiado es baja, si tomamos en consideración que las cartas al editor no son artículos de investigación propiamente dichos. Hay áreas de las ciencias médicas como la medicina familiar que pudiendo haber aportado sus experiencias en el trabajo investigativo en la comunidad, aún no lo han hecho en este período de tiempo(AU)

ABSTRACT Introduction: Since the first case of SARS-CoV-2 was confirmed, the pandemic has experienced an almost uncontrollable increase in the number of cases. The scientific production plays a key role in the fight against the necessary control and eradication of the pandemic. From the very beginning, thousands of articles per day are produced at international level; furthermore, editorials and databases have made a great effort to give due priority and visibility to these contributions. Cuba has made significant efforts in this respect. Objective: To characterize the scientific production on COVID-19 in Cuban medical journals during the first ninety days after the start of the pandemic in Cuba. Material and Methods: A cross-sectional descriptive study aimed at analyzing 100 percent of the scientific medical journals was conducted. Variables such as documental typology, institutional and collaborative affiliations, subject matter, country and time of publication, among others were identified. Results: In total, 58 percent of the articles were published in medical journals and 31,1 percent was a contribution by Medisur Journal, University of Medical Sciences in Cienfuegos. In addition, 77,8 percent of the articles were written by Cuban health researchers, 22,6 percent of the articles were Letters to the Editor and 20,8 percent were original articles. Conclusions: Over the period studied, the national scientific production in Cuban medical journals is low taking into account that the Letters to the Editor are not actual research articles. Some subject areas in Medical Sciences such as Family Medicine, which could have contributed with their experiences in research work within the community, have not produced any scientific article during this period of time(AU)

Internet and doctor–patient relationship: Cross-sectional study of patients' perceptions and practices

Background: With the rapid rolling out of the information highway, an increasing number of patients are accessing the Internet for medical information. Against this background, the present study was undertaken. Objectives: To ascertain patients' use and opinion on impact of Internet on doctor–patient relationship. Methods: A cross-sectional study was done. A total of 709 patients was interviewed, 307 from urban and 402 from rural field practice areas. Institutional ethical approval was obtained before data collection. Categorical data were summarized by percentages with 95% confidence intervals (CIs). Quantitative data were summarized by mean and standard deviation. Associations were explored using odds ratio (OR) with 95% CI for categorical data and two sample t-test for quantitative data. Results: Internet for medical information was used by 50.35% of the patients (95% CI = 46.68, 54.02). More urban patients, i.e., 79.48% used Internet compared to rural patients, i.e., 28.11%. This difference was significant, OR = 9.9 (95% CI = 6.9, 14.0; P < 0.0001). Users of Internet had about 4 years more schooling than nonusers. This was significant, P < 0.0001. More users believed that this trend will improve the doctor–patient relations (51.26%), compared to nonusers (17.05%). This difference was significant, OR = 5.11, 95% CI = 3.61, 7.22, P < 0.0001. Conclusions: A large proportion of patients used Internet to get medical information, significantly more urban patients compared to rural patients. The implication of this is that doctors in times to come will be dealing with patients empowered by online health information.

Privacy Enhanced Healthcare Information Sharing System for Home-Based Care Environments / 대한의료정보학회지

OBJECTIVES: Home-based nursing care services have increased over the past decade. However, accountability and privacy issues as well as security concerns become more challenging during care provider visits. Because of the heterogeneous combination of mobile and stationary assistive medical care devices, conventional systems lack architectural consistency, which leads to inherent time delays and inaccuracies in sharing information. The goal of our study is to develop an architecture that meets the competing goals of accountability and privacy and enhances security in distributed home-based care systems. METHODS: We realized this by using a context-aware approach to manage access to remote data. Our architecture uses a public certification service for individuals, the Japanese Public Key Infrastructure and Health Informatics-PKI to identify and validate the attributes of medical personnel. Both PKI mechanisms are provided by using separate smart cards issued by the government. RESULTS: Context-awareness enables users to have appropriate data access in home-based nursing environments. Our architecture ensures that healthcare providers perform the needed home care services by accessing patient data online and recording transactions. CONCLUSIONS: The proposed method aims to enhance healthcare data access and secure information delivery to preserve user's privacy. We implemented a prototype system and confirmed its feasibility by experimental evaluation. Our research can contribute to reducing patient neglect and wrongful treatment, and thus reduce health insurance costs by ensuring correct insurance claims. Our study can provide a baseline towards building distinctive intelligent treatment options to clinicians and serve as a model for home-based nursing care.

An empirical study on patients′risk of access to online medical information / 中华医院管理杂志

Objective To explore the critical risk points and major current threats for patients to access online medical information. Methods The patient perception value questionnaire was used, to sample survey 1 164 patients with online medical experiences from hospitals in Zhejiang province in January 2018.Their risks in accessing online medical information was evaluated.The evaluation results were ranked according to their importance and satisfaction, and a cross comparison was made between the two, to identify the top ranking factors and the highest difference factor.Descriptive statistics and related analysis methods were used for the data so obtained.Results Health risks and privacy risks were the highest concerns for patients in accessing online medical information.Among the risk factors, information content credibility and transmission channel credibility rank top two.A cross-comparison found that factors of good risk control for online medical information were information author credibility, transmission mode reliability and service risk in turn. The factor of the worst risk control was privacy, while the most problematic risk points were information type credibility and transmission channel credibility.Conclusions The present focus should be placed on the factors of privacy risks and the credibility of information delivery channels, and the main cause of risks is the regulatory awareness.In this consideration, it is suggested that the relevant risk indicators be hierarchically managed according to the current perception characteristics in patients′ online medical access risks, with measures taken accordingly to minimize their risk in such information access.

Evaluation of postoperative complications registration status of gastric cancer by medical information: A single center feasibility study / 中华胃肠外科杂志

Objective@#To explore the feasibility of assessing complications registration through medical information.@*Methods@#A descriptive case series study was performed to retrospectively collect medical information and complication registration information of gastric cancer patients at Department of Gastrointestinal Cancer Center Ward I, Peking University Cancer Hospital from November 1, 2016 to March 1, 2017 (the first period), and from November 1, 2018 to March 1, 2019 (the second period). Case inclusion criteria: (1) adenocarcinoma confirmed by gastroscopy and biopsy; (2) patients undergoing open surgery or laparoscopic radical gastrectomy; (3) complete postoperative medical information and complication information. Patients who were directly transferred to ICU after surgery and underwent emergency surgery were excluded. Because difference of the complication registration procedure at our department existed before and after 2018, so the above two periods were selected to be used for analysis on enrolled patients. The prescription information during hospitalization, including nursing, medication, laboratory examination, transference, surgical advice, etc. were compared with the current Standard Operating Procedure (SOP, including preoperative routine examinations, inspection, perioperative preventive antibiotic use, postoperative observational tests, inspection, routine nutritional support, prophylactic anticoagulation, and prophylactic inhibition of pancreatic enzymes, etc.) for gastric cancer at our department. Medical order beyond SOP was defined as medical order variation. Postoperative complication was diagnosed using the Clavien-Dindo classification criteria, which was divided into I, II, IIIa, IIIb, IVa, IVb, and V. Medical order variation and complication registration information were compared between the two periods, including consistence between medical order variation and complication registration, missing report, underestimation or overestimation of medical order variation, and registration rate of medical order variation [registration rate = (total number of patients–number of missing report patients)/total number of patients], severe complications (Clavien-Dindo classification ≥ III), medical order variation deviating from SOP and the corresponding inferred grading of complication. The data was organized using Microsoft Office Excel 2010.@*Results@#A total of 177 gastric cancer patients were included in the analysis. The first period group and the second period group comprised 89 and 88 cases, respectively. The registrated complication rate was 23.6% (21/89) and 36.4% (32/88), and the incidence of severe complication was 2.2% (2/89) and 4.5% (4/88) in the first and the second period, respectively. The complication rate inferred from medical order variation was 74.2% (66/89) and 78.4% (69/88), and the incidence of severe complication was 7.9% (7/89) and 4.5% (4/88) in the first and second period, respectively. In the first and second period, the proportions of medical order variation in accordance with registered complication were 36.0% and 45.5% respectively; the proportion of underestimation, overestimation and missing report were 5.6% and 4.5%, 4.5% and 4.5%, 53.9% and 45.5%, respectively; the registration rate of medical order variation was 46.1% and 54.5%; the number of case with grade I complications inferred from medical order variation was 34 (38.2%) and 25 (28.4%), respectively; and the number of grade II was 12 (13.5%) and 15 cases (17.0%), respectively. The reason of the missing report of medical order variation corresponding to grade I complication was mainly the single use of analgesic drugs outside SOP, accounting for 76.5% (26/34) and 64.0% (16/25) in the first and second period respectively, and that corresponding to grade II complication was mainly the use of non-prophylactic antibiotics, accounting for 9/12 cases and 5/15 cases, respectively.@*Conclusions@#Medical information can evaluate the morbidity of complication feasibly and effectively. Attention should be paid to routine registration to avoid specific missing report.

Analysis of diseases distribution in Medical Information Mart for Intensive Care Ⅲ database / 中华危重病急救医学

Objective To study the distribution of diseases in Medical Information Mart for Intensive Care Ⅲ(MIMIC-Ⅲ) database in order to provide reference for clinicians and engineers who use MIMIC-Ⅲ database to solve clinical research problems. Methods The exploratory data analysis technologies were used to explore the distribution characteristics of diseases and emergencies of patients (excluding newborns) in MIMIC-Ⅲ database were explored; then, neonatal gestational age, weight, length of hospital stay in intensive care unit (ICU) were analyzed with the same method. Results In the MIMIC-Ⅲ database, 46 428 patients were admitted for the first time, and 49 214 ICU records were recorded. There were 26 076 males and 20 352 females; the median age was 60.5 (38.6, 75.6) years, and most patients were between 60 and 80 years old. The first diagnosis in the disease spectrum analysis was firstly ranked by circulatory diseases (32%), followed by injury and poisoning (14%), digestive system disease (8%), tumor (7%), respiratory disease (6%) and so on. Patients with ischemic heart disease accounted for the largest proportion of circulatory disease (42%), the proportion of these patients gradually increased with age of 60-70 years old, then decreased. However, the proportion of patients with cerebrovascular disease declined first and then increased with age, which was the main cause of death of circulatory system disease (ICU mortality was 22.5%). Injury and poisoning patients showed a significant decrease with age. Digestive system diseases were younger than the general population (most people aged between 50 to 60 years), and non-infectious enteritis and colitis were the main causes of death (ICU mortality was 18.3%). Respiratory infections were predominant in infected patients (34%), but circulatory system infections were the main cause of death (ICU mortality was 25.6%). Secondly, in the neonatal care unit, premature infants accounted for the vast majority (82%). As the gestational age increased, the duration of ICU was decreased, and the mortality was decreased. Conclusions The diseases distribution of patients can be provided by MIMIC-Ⅲ database, which helps to grasp the overview of the volume and age distribution of the target patients in advance, and carry out the next step of research. Meanwhile, it points out the important role of exploratory data analysis in electronic health records analysis.

Incidence and risk factors of hyperkalaemia after acute kidney injury in cardiology department / 实用医学杂志

Objective To investigate the incidence of hyperkalaemia and analyze the risk factors in pa-tients with acute kidney injury(AKI)in cardiology department.Methods We conducted a retrospective case-con-trol study,using the electronic medical information of the patients in Guangdong General Hospital. Results A to-tal of 37 837 patients were included in this study and 1 571(4.3%)patients with AKI were detected.Hyperkalae-mia occurred in 517 patients(1.4%).The incidence of hyperkalaemia in AKI patients was higher than that in non-AKI patients(10.1% vs. 1.0%,P < 0.001)and the incidences of hyperkalaemia at AKI stage 1~3 were 2.6 %, 13.9% and 20.6 %,respectively. Multiple logistic regression analysis demonstrated that AKI stages,chronic kid-ney disease and heart failure were risk factors for hyperkalaemia.AKI and hyperkalaemia were related to increased hospitalization expenses,delayed hospital stay,renal replacement therapy and in-hospital mortality. Based on AKI,the combination of hyperkalemia could significantly increase clinical burden and adverse outcomes. Conclu-sion In cardiology department,the monitoring of serum creatinine and potassium level should be emphasized.
