The theory uses systematic indicators to evaluate the prognosis of patients with chronic heart failure and scientifically analyze the complex factors behind the disease which can provide patients with professionalism, standardization and individualized high-quality medical resources and provide a reference for effectively improving the quality of life.

Objective To explore the implementation effect of nurses′ hierarchical training plan based on training outline and nurses′ needs. Methods Nurses′ hierarchical training outline was established in accordance with three theoretical training modules(humanistic accomplishment, professional competence, career planning/development) as well as three skill training modules(basic nursing skills, specialist nursing skills and first aid nursing skills); the training needs of nurses were investigated by adopting a self-made Training Needs Questionnaire, then the hierarchical training plan was developed based on the training outline and nurses′ training needs. Results There were some differences in the training needs of different levels of nurses in the fields of clinical knowledge and skills,nursing management, nursing education, scientific research and new nursing guidelines and progress(F=2.80-22.47,P<0.05 or 0.01). Before the implementation of nurses′ hierarchical training plan based on training outline and nurses′ needs, nurses′ satisfaction about training, theoretical examination result, clinical working ability and patients′satisfaction towards nursing were 89.06%(228/256),94.80%(1 185/1 250), 96.63%(1 060/1 097) and 95.35%(5 470/5 737), respectively. Then, after the implementation, the corresponding values got improved into 96.76%(239/247), 97.44%(1 297/1 331), 98.75%(1 106/1 120) and 99.22%(6 070/6 118),which were statistically significant(χ2=11.11-176.27,P<0.01). Conclusion Integrating nurses′hierarchical training outline with the training needs helps to provide targeted hierarchical training so as to improve the professional quality of nurses and the patients′satisfaction towards nursing.

Objective? To investigate the correlation between post traumatic growth, social support and resilience in patients with breast cancer, and to provide reference for intervention programme on enhancing positive psychological quality. Methods? Totally 180 patients with breast cancer from 4 ClassⅢ Grade A hospitals in Jiangsu Province were selected by convenience sampling method from June to October in 2018. They were investigated with General Information Questionnaire, Post Traumatic Growth Inventory (PTGI), Social Support Rating Scale (SSRS), and Connor-Davidson Resilience Scale (CD-RISC). Results? In breast cancer patients, the total scores of PTGI, SSRS and CD-RISC were (62.52±17.59), (35.15±9.29) and (56.51±18.33) scores. Correlation analysis showed that the total scores of PTGI and its each dimension were positively correlated with the total scores of SSRS, as well as the total scores of CD-RISC and its each dimension (P＜0.01); the total scores of SSRS and its each dimension were positively correlated with the total scores of CD-RISC and its each dimension (P＜ 0.01). Multivariate linear regression analysis showed that resilience, methods of disease detection, and treatment plans were independent influencing factors of PTG in patients with breast cancer. Both social support and resilience could positively predict PTG, whose path coefficients were 0.493 and 0.302, respectively. Resilience was a mediator of social support and PTG. The indirect effect was 0.080. Conclusions? Resilience plays an important role in mediating between social support and PTG in patients with breast cancer. The resilience training could promote patients' PTG ability .

Objective? To assess the application effects of internet-delivered cognitive-behavioral therapy(ICBT) on symptom management in cancer patients. Methods? All randomised controlled trials (RCTs) about applying ICBT in symptom management in cancer patients in the following databases were searched from the establishment date up until 20th August 2018: Web of Science, PubMed, Cochrane Library, Embase, CBMdisc, Chinese National Knowledge Infrastructure databases(CNKI) and Wanfang. After literature screening, data extraction and quality evaluation, RevMan 5.3 software was used for meta-analysis. Results? Finally, 11 RCT studies were included, totaling 2329 subjects. The results showed that ICBT was beneficial to improve mental distress [SMD=5.02, 95%CI (0.80, 9.25), P=0.02], sleep quality [SMD=0.35, 95%CI (0.02, 0.68), P=0.04]and cancer-related fatigue [SMD=0.50, 95%CI (0.01, 0.99), P=0.04]; but ICBT did not have depression relieving effects in cancer patients (P＞0.05). Conclusions? ICBT is beneficial to reduce psychological pain, improve sleep quality and alleviate cancer-related fatigue in cancer patients, but it has no obvious advantage in alleviating depression. Future studies still need to focus on specific cancer types and validate them with multi-center, large-sample and long-term intervention studies.

Objective: Depression was common during coronavirus disease-2019 (COVID-19) pandemic, while the association of perceived stress with depression among vaccinated healthcare workers has not been investigated. This study aimed to address this issue. Methods: We included a total of 898 fully vaccinated healthcare workers during the outbreak of severe acute respiratory syndrome coronavirus 2 Delta variant in Nanjing, 2021. Depression was ascertained by Patient Health Questionnaire-9, with a cut-off score of ≥5 indicative of mild-to-severe depression. Perceived stress, resilience, and compassion fatigue were assessed by Perceived Stress Scale-10, Resilience Scale-25, and Professional Quality of Life Scale version-5, respectively. Logistic regression analyses were used to estimate the odds ratio (OR) and 95% confidence interval (CI), along with subgroup and mediation analyses. Results: The prevalence of mild-to-severe depression was 41.1% in vaccinated healthcare workers. The odd of mild-to-severe depression was increased with higher perceived stress. Compared with vaccinated healthcare workers with the lowest tertile of perceived stress, those with the highest tertile had increased odds of mild-to-severe depression by 120% (OR 2.20, 95% CI 1.46 to 3.31) after multivariable-adjustment. However, perceived stress was not associated with mild-to-severe depression in vaccinated healthcare workers with strong resilience, but was in those with weak resilience (pinteraction=0.004). Further analysis showed that compassion fatigue mediated the relationship between perceived stress and mild-to-severe depression, with a mediating effect of 49.7%. Conclusion Perceived stress was related to an increased odd of mild-to-severe depression in vaccinated healthcare workers during COVID-19 pandemic, and this relationship might be explained by compassion fatigue.
