ABSTRACT
Objective:To explore the role and effect of problem-based learning (PBL)-based scenario simulation teaching in the standardized residency training in the department of critical care medicine.Methods:A total of 48 residents who received standardized residency training in the Department of Critical Care Medicine of the First Affiliated Hospital of Soochow University from March 2019 to December 2019 were randomly divided into the experimental group and the control group, with 24 ones in each group. The experimental group used PBL-based scenario simulation teaching, while the control group adopted the traditional teaching. After the end of the teaching, the exam scores of the two groups were observed and compared. Then the questionnaire was used to analyze the differences of the results. SPSS 17.0 was used for t-test. Results:The scores of theoretical assessment (85.50±5.15) and skill assessment (82.38±5.64) in the experimental group were higher than those in the control group[(77.04±8.69) and (70.92±5.65)], and the differences were statistically significant ( P < 0.05). The experimental group was higher than the control group in improving learning interest and efficiency, improving clinical work ability, strengthening clinical thinking ability, improving teamwork ability, and improving doctor-patient communication ability, and the difference was statistically significant ( P < 0.05). Conclusion:The PBL-based scenario simulation teaching has more advantages over the traditional teaching and is worthy of promotion.
ABSTRACT
Objective:To analyze the clinical characteristics and outcomes of critically ill pregnant and parturient women in intensive care unit (ICU), and to provide clinical experience for the subspecialty construction of critical obstetrics.Methods:The clinical data of critically ill pregnant and parturient women admitted to the department of critical care medicine, the Second Affiliated Hospital of Kunming Medical University from January 2011 to December 2019 were collected. The main reasons for maternal transfer to ICU, the causes of maternal death, and organ support measures, etc. were summarized.Results:A total of 39 567 critically ill pregnant and parturient women were admitted to the department of obstetrics in our hospital, and 360 were transferred to ICU, with an average ICU transfer rate of 0.91%. Since 2016, the number of obstetric admissions, the number of ICU transfers and the ICU transfer rate had increased significantly. The average age of severe maternals admitted to ICU was (30.9±5.7) years old. The average acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score was 7 (4, 10). The average length of ICU stay was 1 (1, 2) day. The average ventilator duration was 9.0 (3.0, 17.5) hours. The main delivery mode of pregnant women in ICU was cesarean section (84.72%). Forty-eight patients (13.33%) underwent hysterectomy, of which 42 (87.5%) due to postpartum hemorrhage. The top 3 causes of ICU admission were severe postpartum hemorrhage [36.94% (133/360)], hypertensive disorders of pregnancy [21.67% (78/360)], pregnancy with cardiac disease [15.00% (54/360)]. The leading cause of postpartum hemorrhage in women transferred to ICU was placental abnormality [63.98% (103/161)], followed by uterine atony [28.57% (46/161)]. The average blood loss was (4 019±2 327) mL within 24 hours after delivery, and the number of women who underwent hysterectomy due to postpartum hemorrhage decreased year by year. During the study period, there were 2 maternal deaths, which were indirect obstetric deaths, 3 cases were discharged against-advice (expected death), including 1 indirect death and 2 direct obstetric death; the mortality in ICU was 1.39% (5/360).Conclusions:The most common reasons for pregnant and parturient women to be admitted to ICU were severe postpartum hemorrhage and hypertensive disorders of pregnancy. The leading cause of postpartum hemorrhage was placental problem. Indirect obstetric deaths exceeded direct obstetric deaths, mainly due to pregnancy complicated with cardiac disease and severe pneumonia. ICU has become an important battlefield for rescuing critically ill maternal and an important guarantee for reducing the maternal mortality.
ABSTRACT
Objective To investigate the current state of sedation,analgesia and blood glucose management in intensive care units (ICUs) of county hospitals in Guizhou Province of China,and to provide the evidences for improving quality control in critical care medicine.Methods In March 2018,3-4 ICUs of hospitals in every prefecture (one hospital per county) in Guizhou Province were visited to do the field survey.The patients' nursing records within 24 hours after ICU admission were reviewed,and the information such as gender,age,major diagnosis at the ICU admission,the time of admission,were collected.Moreover,the conditions about sedation and analgesia drug use and monitoring,blood pressure,blood glucose as well as and the usage of insulin and ventilator were recorded.Because not all the needed information of every ICU or patient was obtained,only the numbers of the ICUs and patients whose required information had been obtained were analyzed.Results Twenty-eight county hospitals in nine prefectures of Guizhou Province and 152 ICU patients were surveyed.There was a median of 5 (4,7) patients stayed in every ICU on the day of survey.A total of 152 patients were enrolled,with 102 male (67.1％) and 50 female (32.9％);the median age was 65.0 (51.5,74.8) years old;the major diagnosis at ICU admission was mainly cerebral diseases which accounted for 50.0％ (76/152),and the second place was digestive system diseases which accounted for 13.8％ (21/152);53.8％ (78/145) of patients were admitted to ICUs during 08:00-18:00.The percentages of ICUs which had patients received sedation and analgesia were 92.6％ (25/27) and 88.9％ (24/27) respectively,while only 44.4％ (12/27) and 18.5％ (5/27) of them were evaluated the depth of sedation and the level of pain respectively.There was 49.0％ (71/145) of patients received sedation,and 33.8％ (24/71) of them was evaluated by sedation scores;49.7％ (72/145) of patients received analgesia,and 13.9％ (10/72) of them were evaluated by pain scores.The proportions of invasive mechanical ventilation in the patients with sedation or analgesia were both higher than those in the patients without sedation or analgesia [sedation compared with non-sedation:85.9％ (61/71) vs.21.6％ (16/74),analgesia compared with non-analgesia:87.5％ (63/72)vs.19.2％ (14/73),both P ＜ 0.01].The incidence of hypotension was similar between the sedated patients and the non-sedated patients [55.9％ (38/68) vs.40.3％ (29/72),P ＞ 0.05],while the incidence of hypotension was higher in the patients with analgesia as compared with that in the patients without analgesia with significant difference [56.9％ (41/72) vs.38.2％ (26/68),P ＜ 0.05].Within 24 hours after ICU admission,there were 40.7％ (59/145) and 5.5％ (8/145)of patients had hyperglycemia (random blood glucose level ≥ 11.1 mmol/L) or hypoglycemia (random blood glucose level ＜≤ 3.9 mmol/L) respectively.No insulin was used to control the blood glucose level in the patients who had hypoglycemia or did not have hyperglycemia.However,only 23.7％ (14/59) of patients with hyperglycemia were treated with insulin,the initiation of insulin therapy was triggered when median blood glucose level was 19.8 (16.8,24.5) mmol/L.Conclusions The evaluation of analgesia and sedation in the ICUs of county hospitals in Guizhou Province was seriously inadequate and needed to be strengthened urgently.Moreover,the strategy of blood glucose management was also needed to be improved.
ABSTRACT
Objective To explore the effect of risk assessment method on the incidence of healthcare-associated infection (HAI) in high-risk departments.Methods A hospital was selected as the research object, risk assessment of HAI management at the hospital and department level was carried out, high-risk departments and high-risk links were screened out, targeted intervention was performed. Patients hospitalized in April-June 2017 were as control group and those hospitalized in July-September 2017 were as intervention group, incidence of HAI between two groups was compared.Results Through risk assessment at the hospital level, department of critical care medicine was the department with the highest risk, risk assessment at the department level showed that without wearing isolation clothes when contacting isolated patients during diagnosis and treatment, without using sterile sheeting when catheterization, and low correct rate of hand hygiene were high-risk links in department of critical care medicine. Targeted intervention was performed, isolation clothing allocation rate for contacting isolated patients increased from 0 to 100％, compliance rate to wearing isolation clothing among medical staff increased from 0 to 97.62％, implementation rate of using sterile sheet for deep vein catheterization increased from 72.50％ to 100％; hand hygiene correct rate increased from 85.00％ to 96.59％. Incidence of HAI decreased from 5.90％ to 2.64％, difference was statistically significant (P＜0.05).Conclusion Implementing risk assessment management of HAI in medical institutions can effectively guide the prevention and control of HAI in high-risk departments, and improve the level of HAI management.
ABSTRACT
Objective To explore the impact of diagnosis related groups (DRGs) payment and drug zero plus on the management of intensive care medicine department. Methods The clinical data of patients in one year from 2016 to 2017 admitted into the Department of ICU in Liuzhou Worker's Hospital concerning their numbers of discharged patients, transferred patients, bed utilization rate, number of bed turnover, average length of stay of discharged patients, cure and improvement rates, admission and discharge diagnostic coincidence rate, 3-day definite diagnosis rate, clinicopathological diagnosis coincidence rate, rescue success rate, total income, drug proportion, consumable proportion, DRGs payment and settlement data, etc were retrospectively analyzed to explore the dual challenges, DRGs payment and drug zero plus, facing the department and how to respond and deal with them. Results In 2016 and 2017, the total incomes of the department of critical care medicine in our hospital were 42.107 0 million yuan and 41.371 3 million yuan respectively, and the medical insurance incomes were 15.03 million yuan and 16.69 million yuan respectively;in 2016 and 2017, 2 693 patients and 2 922 patients were admitted and treated respectively; 595 patients and 577 patients were discharged respectively, with 2 071 patients and 2 334 patients transferred respectively; the balances of the department were 15.48 million yuan and 29.11 million yuan, respectively. From July to December 2017, the medical insurance DRGs payment data suggested that the proportion of loss of the department be 7.02%. Accelerating the Grade 6 electronic medical records and informationization construction, adopting the severe disease information solution program and fine quality control management in the department of critical care medicine can reduce the cost of manpower. Conclusion Our future development direction in the Department of Intensive Care Medicine includes the following aspects: Open source and reduce expenditure, strictly control the proportions of drugs and consumables, improve the balance of the department, and actively respond and deal with the medical insurance DRGs payment.
ABSTRACT
Objective To investigate the effect of maximal sterile barrier precaution during deep venous/arterial catheterization on preventing catheter-related bloodstream infection (CRBSI)in patients in the department of critical care medicine.Methods 996 patients who were hospitalized in Beijing Friendship Hospital and underwent deep ve-nous/arterial catheterization from September 2011 to April 2014 were analyzed retrospectively,patients were divided into standard sterile barrier precaution group (SSB group,September 2011-December 2012,n=560)and maximal sterile barrier precaution group (MSB group,January 2013-April 2014,n=436)based on whether they received maximal sterile barrier precaution,incidence of CRBSI and mortality were compared between two groups.Results There was no statistical difference in constitute of intubation sites between patients in SSB group and MSB group(χ2=6.750,P=0.08).The incidence of CRBSI per 1000 catheter days in SSB group and MSB group were 2.41‰(1.64‰-4.02‰)and 1.91‰(0‰-4.56‰)respectively,rank test revealed no significant difference(Z=-0.057, P>0.05);24 (4.29%)patients in SSB group and 26(5.96%)patients in MSB group developed CRBSI,difference between two groups was not statistically significant(χ2=1.447,P>0.05).The mortality in SSB group and MSB group were (18.43±5.53)% and (11.68±4.14)% respectively,independent sample t-test revealed that difference was significant(t=3.907,P<0.05).Conclusion Maximal sterile barrier precaution did not reduce the incidence of CRBSI.
ABSTRACT
ObjectiveTo screen the colonization of multidrug resistant organisms (MDROs) and determine their risk factors in intensive care unit (ICU), so as to provide the basis of prophylaxis and treatment of MDROs colonization.Methods A prospective single-center study was conducted in ICU of China-Japan Friendship Hospital from June 2008 to December 2014. The nostril and anal swabs for each patient who stayed in ICU over 24 hours were collected. Each specimen was cultured and tested for drug sensitivity. Clinical findings and relative risk factors were collected. The risk factors of MDROs colonization were analyzed with univariate analysis. The independent risk factor was selected from the risk factors withP 9 days (OR = 1.766, 95%CI = 1.235 - 3.986,P = 0.021) were independent risk factors of MDROs colonization on admission to ICU.ConclusionsHigh prevalence of MDROs colonization in ICU patients was found in our hospital, and ESBL enterobacteria was the predominant bacteria. ICU acquired MDROs colonization is also worth considering, especially for MDR-AB. Identification of risk factors for MDROs colonization may help identify and screen patients with high risk, and it is also instructive in prophylaxis of MDROs colonization/infection and restriction of the use of broad spectrum antibiotics.
ABSTRACT
Objective To study the diagnostic accuracy of bedside lung ultrasound examination in chronic obstructive pulmonary disease (COPD) and cardiac pulmonary edema.Methods A prospective pilot and single-blind trial was conducted.A total of 89 patients with respiratory failure admitted to the Department of Critical Care Medicine of Anhui Provincial Hospital from September 2012 to September 2013 were enrolled.There were 32 patients with COPD,31 patients with cardiac pulmonary edema,8 patients with interstitial lung disease,12 with lung infection,and 6 patients with other diseases.Another group of 30 patients without respiratory disease were enrolled as the control group.Bedside lung ultrasound examinations were performed in all patients within 24 hours,and chest radiograph was performed at the same time.The signs to be revealed were the A lines or horizontal lines arising from the pleural line,and the comet-tail artifact (B lines) arising from the lung wall interface.Results Of 89 patients,33 patients were shown a mean of 2.94 ± 1.87 A lines per case with the bedside lung ultrasound,and 38 patients with a mean of 3.27 ± 1.72 B lines per patient.1.94 ± 0.96 A lines a case and 1.74 ± 0.82 B lines a case in control group.There were significant difference between the test group and control group (Aline:t=3.835,P=0.000; B line:t=6.540,P=0.000).Among 32 cases with COPD,28 patients had a positive result of A line with a coincidence rate of 81.2％.In the 31 patients with cardiac pulmonary edema,25 patients presented B line,with a coincidence rate of 80.6％.The A lines or horizontal lines arising from the pleural line showed a sensitivity of 81.30％ and a specificity of 87.70％ with a positive predictive value (PPV) 78.80％ and a negative predictive value (NPV) 89.30％ of in the diagnosis of COPD,and the B lines showed a sensitivity of 80.60％ and a specificity of 77.60％ with a PPV of 65.80％ and a NPV of 88.20％ in the diagnosis of cardiac pulmonary edema.However,X-ray examination showed a sensitivity of 65.50％,a specificity of 86.00％,a PPV of 72.40％ and a NPV of 81.70％ in the diagnosis of COPD,and it showed a sensitivity of 74.20％,a specificity of 69.00％,a PPV of 56.10％ and a NPV of 83.30％ in the diagnosis of cardiac pulmonary edema.Bedside ultrasound was highly consistent with X-ray in diagnosis of COPD [area under receiver operating characteristic curve (AUC):0.833 vs.0.816,P＞0.05],but Kappa value of ultrasound technology A line in the diagnosis of COPD was greater than the value of X-ray imaging techniques (0.685 vs.0.527).There was little diagnostic value of ultrasound A line in cardiac pulmonary edema (AUC was 0.305),while the B line was superior to X-ray (AUC:0.888 vs.0.747,P＜0.001),and had a higher Kappa value than the value of X-ray imaging techniques (0.553 vs.0.481) in cardiac pulmonary edema.Conclusions We conclude that bedside ultrasound is cost-effective,easy for repeated examination,and suitable for differential diagnosis of lung diseases.It might be useful in screening for COPD and cardiac pulmonary edema.
