Objective To explore the cognitive function status and potential influence factors on cognitive function in hospitalized patients with chronic heart failure.Methods Using a cross-sectional research design,CHF patients(n =267,mean age (63.8 ± 9.4) years) were recruited from two care unitsHeart Failure Care Unit and Intensive Care Unit of our hospital.Cognitive function status was evaluated by the Montreal Cognitive Assessment (MoCA) screen test.Results Based on the MoCA score,37.8％ (101/267) patients suffered from cognitive impairment (score ＜ 26),especially on the three specific cognitive functions-memory,langue and executive capability.Multifactorial analysis showed that after controlling for other factors,there was a downward trend on cognitive function with aging (OR =1.09,95％ CI:1.05-1.14) while higher left ventricular ejection fraction (LVEF) was related to better cognitive function (OR =0.97,95％ CI:0.95-0.99) ; patients who took medicine regularly also had better cognitive function (OR =3.71,95％CI:1.40-10.91); cognitive function was better in patients with high level of social support compared those with low social support (OR =0.92,95％ CI:0.88-0.96).Conclusions Incidence of cognitive impairment is high in hospitalized patients with chronic heart failure.Age,LVEF,whether taking medication regularly and social support are factors related to cognitive function in CHF patients.

Objective:To explore the effects of experiential teaching based Carolina care model on humanistic care ability, emotional intelligence and communication skills among undergraduate practice nursing students.Methods:In August 2018, this study selected 80 undergraduate practice nursing students with clinical practice in the Affiliated Hospital of Qingdao University as subjects by conveniences sampling. The experiential teaching based Carolina care model for nursing students was implemented during clinical practice for 6 months. The intervention effects were assessed with the Caring Ability Inventory (CAI) , Emotional Intelligence Scale (EIS) and the Supportive Communicative Scale (SCS) . SPSS 22.0 was used to data analysis. The paired t test was used to compare the scores of CAI, EIS and SCS in undergraduate nursing students before and after intervention. Results:After intervention, the scores of CAI, EIS and SCS of undergraduate practice nursing students were (224.31±15.98) , (135.43±11.50) and (78.80±7.90) respectively higher than those [ (194.23±19.73) , (133.75±12.17) and (74.58±8.23) ]before intervention with statistical differences ( t=24.11, 2.20, 3.00; P<0.05) . Conclusions:Carolina care model based experiential teaching can improve humanistic care ability, emotional intelligence and communication skills of undergraduate practice nursing students.

【Objective】 To explore the effect of intelligent closed-loop mobile nursing management system in quality management of blood transfusion. 【Methods】 The mobile nursing system and the cold chain management system of our hospital were integrated to realize intelligent closed-loop management of blood transfusion. After consulting medical records, 789 blood recipients, admitted to the Department of Hematology of our hospital from January to December 2017 (before the implementation of closed-loop management), were selected as the control group, and 836 blood recipients, admitted during January to December 2018 (after the implementation of closed-loop management), were selected as the observation group. A self-designed blood transfusion standard management checklist was adopted, with the number of standard execution items as the numerator and the total number of checked items as the denominator to obtain the standard implementation rate. The checking rate of blood sample collection, blood transfusion rate within 30 min after blood issuing, the execution rate of double check specification and inspection specification, the completion rate of RBCs transfusion within 4 h and qualified rate of blood transfusion nursing record before and after the implementation of closed-loop management were compared by chi-square test or Fisher's exact probability method to evaluate the efficacy of blood quality management improvement. A total of 8 head nurses from clinical departments (Hematology Department, Cardiac Surgery Department, Operating Room, Comprehensive ICU) involved in blood transfusion were selected for semi-structured interviews. The interviews focused on the effect of intelligent closed-loop mobile nursing information system in quality management of clinical blood use, and the results of the interviews were analyzed. 【Results】 The double check execution rate of blood transfusion, the checking rate of blood sample collection specification, the transfusion rate within 30 min after blood issuing, the execution rate of blood transfusion inspection, the completion rate of RBCs transfusion within 4 h, the qualified rate of blood transfusion nursing record in the observation group and the control group after and before the implication of the intelligent closed-loop mobile nursing management system were 100%(836/836) vs 97.72%(771/789), 99.04%(828/836) vs 97.34%(768/789), 97.97%(819/836) vs 95.06%(750/789), 99.28%(830/836) vs 94.93%(712/789), 99.16%(829/836) vs 97.47%(769/789) and 100%(836/836) vs 89.73%(708/789), respectively, showing significant improvement (P < 0.05). The time spend on the record, summary and feedback of quality control results was significantly shortened. 【Conclusion】 The application of intelligent closed-loop mobile nursing management system in the quality management of clinical blood use can effectively improve the efficiency of blood transfusion, nursing quality and the safety of clinical blood use.
