Exploring the influencing factors of patient safety competency of clinical nurses: a cross-sectional study based on latent profile analysis.

BACKGROUND: Clinical nurses play an important role in ensuring patient safety. Nurses' work experience, organizational environment, psychological cognition, and behavior can all lead to patient safety issues. Improving nurses' attention to patient safety issues and enhancing their competence in dealing with complex medical safety issues can help avoid preventable nursing adverse events. Therefore, it is necessary to actively identify the latent profiles of patient safety competency of clinical nurses and to explore the influencing factors. METHODS: A cross-sectional design was conducted. A total of 782 Chinese registered nurses were included in the study. Demographic characteristics questionnaire, Error Management Climate scale, Security Questionnaire, Proactive Behavior Performance scale and Patient Safety Competency Self-Rating Scale of Nurses were used. Latent profile analysis (LPA) was performed to categorize nurses into latent subgroups with patient safety competency differences. Multinomial logistic regression was conducted to explore the influencing factors of nurses' patient safety competency (PSC) in different latent profiles. RESULTS: A total of 782 questionnaires were valid. Nurses' PSC was positively related to error management climate, and psychological safety and proactive behavior. The PSC score was 121.31 (SD = 19.51), showing that the PSC of clinical nurses was at the level of the medium on the high side. The error management climate score was 70.28 (SD = 11.93), which was at a relatively high level. The psychological safety score was 61.21 (SD = 13.44), indicating a moderate to low level. The proactive behavior score was 37.60 (SD = 7.33), which was at a high level. The latent profile analysis result showed that three groups of profile models were fitted acceding to the evaluation of PSC. They were defined as Low-competency Group (74 (9.5%)), Medium-competency Group (378 (48.3%)) and High-competency Group (330 (42.2%). Working years, professional titles, departments, error management climate, psychological security and proactive behavior were the influencing factors of PSC in three latent profiles. CONCLUSIONS: The PSC of clinical nurses had obvious classification characteristics, and the main influencing factors were working years, professional titles, working departments, error management climate, psychological security and proactive behavior. This study suggests that managers should pay attention to the continuous cultivation of patient safety competence among clinical nurses, provide targeted intervention measures for nurses at different work stages, professional titles, and departments, and use efficient management strategies to create a positive error management atmosphere. In patient safety management, providing nurses with more psychological security is conducive to stimulating more proactive behaviors and continuously improving the level of patient safety competence.

Anxiety and depression during 3-year follow-up period in postoperative gastrointestinal cancer patients: prevalence, vertical change, risk factors, and prognostic value.

BACKGROUND: Anxiety and depression are common issues in gastrointestinal cancer, bringing negative impacts on patients' quality of life and long-term prognosis. This study aimed to identify the prevalence, longitudinal variation, risk factors, and prognostic value of anxiety and depression in postoperative gastrointestinal cancer patients. METHODS: A total of 320 gastrointestinal cancer patients after surgical resection (210 colorectal cancer (CRC) patients and 110 gastric cancer (GC) patients) were enrolled in this study. During the 3-year follow-up period, Hospital Anxiety and Depression Scale (HADS)-anxiety (HADS-A) and HADS-depression (HADS-D) scores were determined at baseline, 12th month (M12), 24th month (M24), and 36th month (M36). RESULTS: The prevalence of anxiety and depression at baseline was 39.7% and 33.4% in postoperative gastrointestinal cancer patients, respectively. Female (vs. male), single/divorced/widowed (vs. married), CRC (vs. GC), hypertension, higher TNM stage, neoadjuvant chemotherapy, and postoperative complications were independent risk factors of anxiety or depression in patients with gastrointestinal cancer (all P < 0.050). Furthermore, anxiety (P = 0.014) and depression (P < 0.001) were associated with shortened overall survival (OS); after further adjustment, depression was independently linked with shortened OS (P < 0.001), while anxiety was not. During the follow-up period, HADS-A score (from 7.78 ± 3.180 to 8.57 ± 2.854, P < 0.001), HADS-D score (from 7.23 ± 2.711 to 8.01 ± 2.786, P < 0.001), anxiety rate (from 39.7 to 49.2%, P = 0.019), and depression rate (from 33.4 to 42.6%, P = 0.023) were all gradually increased from baseline to M36. CONCLUSION: Anxiety and depression gradually exacerbate and relate to poor survival in postoperative gastrointestinal cancer patients.

Reminiscence therapy involved care programs as an option to improve psychological disorders and patient satisfaction in elderly lung cancer patients: A randomized, controlled study.

Objective: Reminiscence therapy (RT) is frequently used with elderly patients to improve their psychological status, but a few studies have examined its application in lung cancer patients. This study explored whether a reminiscence therapy-involved care program (RTICP) could improve cognitive functions, anxiety, depression, patient satisfaction, and survival in elderly lung cancer patients. Materials and Methods: This randomized, controlled study enrolled 138 elderly post-operative lung cancer patients into two groups, an RTICP group (n = 69) and a usual care program (UCP) group (n = 69), for a 12-month intervention period and a follow-up period. During the 12-month intervention, the Mini-Mental State Examination (MMSE) score, the Hospital Anxiety and Depression Scale for anxiety (HADS-A) and depression (HADS-D), patient satisfaction, disease-free survival (DFS), and overall survival (OS) were evaluated. Results: MMSE and patient satisfaction were elevated in the RTICP group compared to the UCP group at month (M) 12. Additionally, RTICP reduced HADS-A at M6, M9, and M12 and the anxiety rate at M9, HADS-D at M9, and M12 compared to UCP, whereas the depression rate was no different between the two groups at any time (all P > 0.050). Moreover, DFS and OS were no different between the two groups (all P > 0.050). Conclusion: RTICP, considered as an optional psychological intervention, enhances cognitive functions, alleviates anxiety and depression feelings, and elevates satisfaction among elderly lung cancer patients.

WeChat-based education and rehabilitation program in unprotected left main coronary artery disease patients after coronary artery bypass grafting: an effective approach in reducing anxiety, depression, loss to follow-up, and improving quality of life.

This study aimed to investigate the effect of WeChat-based education and rehabilitation program (WERP) on anxiety, depression, health-related quality of life (HRQoL), major adverse cardiac/cerebrovascular events (MACCE)-free survival, and loss to follow-up rate in unprotected left main coronary artery disease (ULMCAD) patients after coronary artery bypass grafting (CABG). In this randomized controlled study, 140 ULMCAD patients who underwent CABG were randomly assigned to WERP group (n=70) or control care (CC) group (n=70). During the 12-month intervention period, anxiety and depression (using hospital anxiety and depression scale (HADS)) and HRQoL (using 12-Item Short-Form Health Survey (SF-12)) were assessed longitudinally. During the total 36-month follow-up period (12-month intervention and 24-month non-intervention periods), MACCE and loss to follow-up were recorded. During the intervention period, HADS-anxiety score at month 9 (M9) (P=0.047) and month 12 (M12) (P=0.034), anxiety rate at M12 (P=0.028), and HADS-D score at M12 (P=0.048) were all reduced in WERP group compared with CC group. As for HRQoL, SF-12 physical component summary score at M9 (P=0.020) and M12 (P=0.010) and SF-12 mental component summary score at M9 (P=0.040) and M12 (P=0.028) were all increased in WERP group compared with CC group. During the total follow-up period, WERP group displayed a trend of longer MACCE-free survival than that in CC group but without statistical significance (P=0.195). Additionally, loss to follow-up rate was attenuated in WERP group compared with CC group (P=0.033). WERP serves as an effective approach in optimizing mental health care and promoting life quality in ULMCAD patients after CABG.

Impact of workplace incivility in hospitals on the work ability, career expectations and job performance of Chinese nurses: a cross-sectional survey.

OBJECTIVES: The objectives of this study were to investigate new nurses' experiences of workplace incivility; verify the mediating role of work ability in the relationship between workplace incivility and job performance and examine the moderating role of career expectations in the relationship between workplace incivility and job performance. DESIGN: This cross-sectional survey was conducted in China in May 2016. SETTINGS: The research settings included 54 cities across 29 provinces of China. PARTICIPANTS: Of the 903 participants recruited, 696 new nurses (<3 years of nursing experience) agreed to complete the online questionnaire of the study. The effective response rate was 77.1%. The inclusion criteria were voluntary participation, <3 years of nursing experience and recognition as a registered nurse. The exclusion criteria were refusal to participate, >3 years of nursing experience or not recognised as a registered nurse. RESULTS: New nurses (60.7%) experienced some level of workplace incivility in the previous year, and it was more frequent among those with higher educational degrees. Work ability mediated the relationship between workplace incivility and job performance, and this relationship was moderated by career expectations. CONCLUSION: Incivility towards new nurses was relatively common in the workplace. Workplace incivility impairs job performance by weakening the work ability of new nurses. Higher career expectations may buffer workplace incivility and contribute to the maintenance of job performance by buffering the detrimental effects of workplace incivility.

Sirtuin3 protects aged human mesenchymal stem cells against oxidative stress and enhances efficacy of cell therapy for ischaemic heart diseases.

Sirtuin3 (SIRT3) is associated with oxidative stress and lifespan. However, the possible mechanisms underlying its influence are unknown. We hypothesized that SIRT3 increases the antioxidant capacity of aged cells and improves the efficacy of human mesenchymal stem cell (hMSC) therapy for ischaemic heart diseases in aged patients. In vitro, the antioxidant capacity of old hMSCs (O-hMSCs) was increased after SIRT3 overexpression using a gene transfection technique, while the antioxidant capacity of young hMSCs (Y-hMSCs) was decreased by SIRT3 silencing. The levels of forkhead box O3a (FoxO3a) in the nucleus, and antioxidant enzymes Mn-superoxide dismutase (MnSOD) and catalase (CAT) increased in SIRT3-overexpressed O-hMSCs while they decreased in SIRT3-silenced Y-hMSCs after oxidative stress. Following myocardial infarction in adult rats in vivo, infarct size decreased and cardiac function was significantly enhanced after cell transplantation with SIRT3 overexpressed O-hMSCs. The number of apoptotic cells decreased and the survival rate of transplanted cells increased following SIRT3 overexpression in O-hMSCs. SIRT3 protects aged hMSCs against oxidative stress by positively regulating antioxidant enzymes (MnSOD and CAT) via increasing the expression of FoxO3a in the nucleus. The efficacy of aged hMSC transplantation therapy for ischaemic heart diseases can be improved by SIRT3 overexpression.

Suppression of miR-34a Expression in the Myocardium Protects Against Ischemia-Reperfusion Injury Through SIRT1 Protective Pathway.

MicroRNA-34a (miR-34a) is expressed in the myocardium and expression is altered after myocardial injury. We investigated the effects of miR-34a on heart function after ischemia-reperfusion (IR) injury. Cardiomyocytes were isolated from neonatal rat hearts and simulated IR injury was induced in vitro. Following IR injury in rats, infarct size was measured and left ventricular (LV) function was evaluated using echocardiography. Protein expression of silent information regulator 1 (SIRT1), acetylated p53 (ac-p53), Bcl-2 and Bax, and miR-34a and SIRT1 gene levels were analyzed. miR-34a overexpression exacerbated myocardial injury by increasing apoptosis and infarct size and decreasing LV function. Suppression of miR-34a attenuated myocardial IR injury. SIRT1 was negatively regulated by miR-34a and the expression of downstream genes, such as ac-p53, Bcl-2, and Bax were altered correspondingly. Increased expression of miR-34a aggravates injury after IR; miR-34a suppression therapy may represent a new line of treatment for myocardial IR injury.

Decreased SIRT3 in aged human mesenchymal stromal/stem cells increases cellular susceptibility to oxidative stress.

Sirtuin3 (SIRT3) is an important member of the sirtuin family of protein deacetylases that is localized to mitochondria and linked to lifespan extension in organisms ranging from yeast to humans. As aged cells have less regenerative capacity and are more susceptible to oxidative stress, we investigated the effect of ageing on SIRT3 levels and its correlation with antioxidant enzyme activities. Here, we show that severe oxidative stress reduces SIRT3 levels in young human mesenchymal stromal/stem cells (hMSCs). Overexpression of SIRT3 improved hMSCs resistance to the detrimental effects of oxidative stress. By activating manganese superoxide dismutase (MnSOD) and catalase (CAT), SIRT3 protects hMSCs from apoptosis under stress. SIRT3 expression, levels of MnSOD and CAT, as well as cell survival showed little difference in old versus young hMSCs under normal growth conditions, whereas older cells had a significantly reduced capacity to withstand oxidative stress compared to their younger counterparts. Expression of the short 28 kD SIRT3 isoform was higher, while the long 44 kD isoform expression was lower in young myocardial tissues compared with older ones. These results suggest that the active short isoform of SIRT3 protects hMSCs from oxidative injury by increasing the expression and activity of antioxidant enzymes. The expression of this short isoform decreases in cardiac tissue during ageing, leading to a reduced capacity for the heart to withstand oxidative stress.
