Objective To study the effect of new barrel theory in improving evaluation of hospitalized patients. Methods Eight hundred hospitalized patients from September 2012 to August 2013 were randomized equally into the control group and the observation group.The last one or two items affecting patient satisfaction from the control group were used as objectives to be improved.Causal effect analysis was done pertinent to the items and the worksheet was bettered and improved and then enforced.The two groups were compared after intervention with new barrel theory in terms of satisfaction of patients during admission and discharge. Result The satisfaction of patients in the observation group during admission and discharge was significantly better than that in the control group(P<0.05).Conclusion The new barrel theory used to detect the flaws in nursing service and improve the workflow can improve assessment from the patients so that the management quality can be enhanced.

Objective To investigate the risk factors of obstruction of central venous catheter(CVC)in the intensive care unit(ICU). Methods One hundred and thirty-three adult patients in ICU with CVC were included in the study. The difference of the position of catheters, duration of indwelling catheters,selection of sealing solution,blood platelet(PLT)count,prothrombin time(PT),international normalized ratio(INR),activated partial thromboplatin time(APTT),thrombin time(TT)and fibrinogen(FBG)were studied between two groups of patients(with and without the obstruction of CVC).Results In 117 cases,there were no catheter obstruction,accounting for 88.0%. Catheter obstruction occurred in 16 cases,accounting for 12.0%,10 cases of which the catheters were partially blocked,accounting for 7.5%and in 6 cases completely blocked,accounting for 4.5%.There were significant differences in the duration of indwelling catheters,PLT and FBG levels between the two groups of patients(all P<0.05).There was no significant difference in the position of catheters,selection of sealing solution and PT,INR,APTT,TT level between the groups(all P>0.05).Conclusion Prolonged time of indwelling CVC,high levels of PLT and clotting fibrinogen are the risk factors of the obstruction of CVC in ICU patients.

Objective To explore the effects of two methods for deep endotracheal suction.Methods Forty patients who had ineffective airway clearance or lung infections or refused suction were randomly divided into observation group (n=21) and control group (n=19).Temporay airway was established by using oropharyngeal airway.Then,the control group received subglottic suction after pading the shoulder with ordinary pillow (≤10cm),while the observation group received subglottic suction after pading the shoulder with homemade pillow (=15cm).The two groups were compared in terms of sputum suction effect and mucosal injury.Results There was no incidence of mucosal injury in the observation group but three in the control group.The times of suctioning in the observation group were fewer than those of the control group and the volume for suctioning was larger as well (allP<0.05).Conclusion Deep endotracheal suction through oropharyngeal airway,shoulder elevation for 15cm,temporary indwelling of suction tubes can achieve better suction effect without corresponding complications.

Objective To investigate the nutrition status and quality of life(QOL)in the perioperative patients with laryngeal cancer and to analyze the effect of nutrition status on quality of life.Methods Sixty-six patients with laryngeal cancer were surveyed respectively by self-designed general situation questionnaire,nutritional risk srcreening 2002(NRS2002)and European organization for research and treatment of cancer quality of life core questionnaire(EORTC QLQ-C30).The impact of nutritional status on QOL was analyzed by the multiple linear regression analysis.Results The total score of nutritional risk of perioperative patients with laryngeal cancer was 3.53±1.51 and the incidence of nutritional risk was 28.79%.The nutrition status influenced on QOL, physiological function,cognitive function and pain area(P<0.05).Conclusion Nurses should assess the nutritional status of the patients and correct malnutrition without delay in order to improve the physical function and QOL of the patients.

Objective To construct evaluation standards for pediatric nursing responsibility. Methods With the method of expert enquiry for Delphi, coefficient of variation of each index through expert grading and Kendall W′s coordination coefficient were used to test the coordination degree in opinions among experts. After the coefficient of larger variation and lower weight were removed , the elements of nursing duty were ranked based on the weight by using hierarchy analysis method. Results The established practical pediatric nurses responsibility evaluation standard consisted of 3 modules, with 11 dimensions and 33 items. The Cr expert authority coefficient was between 0.77~0.90, with an average of 0.88. The variation coefficient of each index was low, ranging between 0.013 0.135 (<0.25). The Kendall W′s coordination coefficients of the primary, secondary and tertiary indicators were 0.482, 0.552 and 0.438, respectively, with significant differences in the coordination coefficient (P<0.001). Conclusion The experts are active and authoritative in participating in the standard establishment and they highly agreed on the standard , which indicates that the established the standard is reliable in a higher degree.

Objective To apply Plato analysis method to clinical cases which were reported from clinical nursing, finding out the key link of the risks which were related to the cases:the key age, the key period, the key spectrum of disease and the key projects, etc. To carry out the feedforward control of the quality of care, and ensure the quality and safety of nursing. Methods A database were set up including clinical special cases, high-risk cases, security hidden danger cases and emergency cases. Thetwo eightprinciple of Plato analysis method was used to find out the main factors, the principal contradiction, the key hazard and the key problems of the cases, etc. The aim was to provide guidelines of risk analysis, risk prevention and risk aversion for nurses, and improve their consciousness of security hidden danger, and reduce security hidden danger cases. Results The results of 207 cases collected from 2014 to 2015 showed that the main risks involved the age groups were 41-80 years old and 21-30 years old. The major risks involved the spectrum of disease were the nervous system, cardiovascular disease, surgical anesthesia related problems, kidney disease, cancer and respiratory system. The major risks involved the time were the midnight, morning and afternoon. The major risks involved the locations were sickroom, emergency room, auxiliary inspection departments and outpatient. The major risks involved items were disease mutation, psychological problems, medication safety and instrument safety, among the disease mutation, timely discovered, rescued 13 patients with heart and breathing pause, stop 13 patients who attempted suicide. Since the Plato analysis method was applied to identify the security risks of the clinical cases, the number of falling, all kinds of pipe shed, skin problems and suicides were decreased from 6, 6, 7, 5 in 2014 to 2, 2, 2, 1 in 2015, declining trend year by year.
