Prevalence and impact of frailty in patients undergoing colorectal cancer surgery: A systematic review and meta-analysis based on modified frailty index.

Frailty has been linked to unfavorable postoperative outcomes in patients with colorectal cancer (CRC). However, the prevalence of frailty among CRC surgery patients and its association with mortality and postoperative complications, as evaluated by the modified frailty index (mFI), have not been thoroughly investigated and necessitate clarification. PubMed, Web of Science, Embase, and CBM databases were systematically searched for relevant studies (up to January 2024), and the pooled prevalence and odds ratio (OR) estimate were calculated. A total of 16 studies containing 245 747 patients undergoing CRC surgery were included. The prevalence of frailty among CRC surgery patients was 31% (95% confidence interval [CI] = 20%-42%; I2 = 100%, p < 0.001). In patients undergoing CRC surgery, frailty was associated with a higher incidence of postoperative complications (OR = 1.94; 95% CI = 1.47-2.56; I2 = 91.9%, p < 0.001), but it did not exhibit any significant correlation with the 30-day mortality (OR = 5.17; 95% CI = 0.39-68.64; I2 = 94.4%, p < 0.001). Frailty is common in CRC surgery and exerts a significant negative impact on the postoperative outcomes. Future research could explore the potential of the mFI to facilitate a more streamlined and precise quantification of frailty, thereby establishing a refined understanding of its correlation with surgery prognosis.

Relationship among core competency, self-efficacy and transition shock in Chinese newly graduated nurses: a cross-sectional study.

OBJECTIVES: To investigate how core competency and self-efficacy of newly graduated nurses affect their experience of transition shock, and to determine the relationship between these factors. DESIGN: A cross-sectional study. METHODS: 262 newly graduated nurses participated in a cross-sectional study by using demographic data, the transition shock scale, the competency inventory for registered nurses scale and the self-efficacy scale. RESULTS: Among newly graduated nurses, the score of transition shock was 77.641±24.140, the score of core competency was 125 (109.5, 163.5) and the score of self-efficacy was 2.5 (2,3), all of which were at a moderate level. The core competency and self-efficacy of the newly graduated nurses had a negative impact on the transition shock (ß=-0.151, p=0.026; ß=-0.379, p<0.001). Additionally, self-efficacy played a mediating role in the relationship between core competency and transition shock, with a mediating effect accounting for 57.34% of the total effect. CONCLUSIONS: The transition shock of newly graduated nurses was at a moderate level, with the highest level of transition shock occurring within the first year of employment. Self-efficacy plays a mediating role in the relationship between core competency and transition shock. Nursing managers should create standardised training for newly graduated nurses within the first year of employment to reduce their transition shock. This will help improve newly graduated nurses' core competency, enhance self-efficacy and support the graduates. This will alleviate the impact of transition shock on newly graduated nurses, helping them transition smoothly and successfully.

Association between horizontal violence and turnover intention in nurses: A systematic review and meta-analysis.

Background: Horizontal violence is common in nurses. Most published studies have focused on horizontal violence and higher turnover rates in nurses; however, it lacks systematic reviews and meta-analyses. The purpose of this review is to quantitatively assess the correlation between horizontal violence and turnover intention in nurses. Methods: Systematic review and meta-analysis were performed in accordance with PRISMA guidelines. The relationship between horizontal violence and turnover intention in nurses was obtained by systematically searching related literature in four English databases (Cochrane, PubMed, Embase, and CINAHL) and three Chinese databases (SinoMed, CNKI, and Wanfang) (up to 6 March 2022). The relationship between horizontal violence and turnover intention was evaluated using Fisher's z-value, which was then converted to r. STATA 16.0 was used to perform statistical analysis. The random-effects model was performed to synthesize data. Results: A total of 14 studies with 6,472 nurses were included. A low-positive correlation of horizontal violence with turnover intention was found (pooled r=0.32 [0.29-0.34]). Subgroup analysis showed that sample size and quality were not the source of heterogeneity. Measurement tool was the source of heterogeneity. Although geographic region might not be the source of heterogeneity, further subgroup analysis of the country reveals heterogeneity. The funnel plot and Egger's test showed no publication bias. Conclusion: Horizontal violence had a low positive correlation with turnover intention in nurses. Nurses who experienced horizontal violence were more likely to leave or change careers than those who did not experience horizontal violence. This finding helps to draw attention to horizontal violence by nursing managers and implement effective interventions for nurses, so as to reduce nurses' turnover.

The Prevalence of Activities of Daily Living Impairment in Patients With Heart Failure: A Systematic Review and Meta-Analysis.

Objectives: The prevalence of activities of daily living (ADL) in patients with heart failure (HF) reported in current studies were inconsistent, ranging from 11.1 to 70.5%. The purpose of this study is to quantify the prevalence of ADL impairment in HF patients. Methods: PubMed, Embase, Cochrane, CINAHL, CNKI, SinoMed, VIP, and Wanfang databases were systematically searched for relevant studies (up to March 2, 2022). Cross-sectional, case-control, or cohort studies with detailed descriptions of overall ADL impairment in HF were included. Stata 16.0 was used for statistical analysis. Fixed-effect or random-effect model was adopted according to heterogeneity which was evaluated by Cochran's Q and I 2 values. Sensitivity analysis, subgroup analysis, and meta-regression were performed to investigate the sources of heterogeneity. Results: A total of 12 studies with 15,795 HF patients were included in the meta-analysis, and the pooled prevalence of ADL impairment in patients with HF was 38.8% (95%CI: 28.2-49.3%; I 2 = 99.5%, P < 0.001). No possible sources of heterogeneity were found in subgroup analysis and meta-regression. Funnel plots and Egger's test showed no publication bias (P = 0.595). Conclusion: The prevalence of ADL impairment is relatively high in HF patients. Differences in the prevalence of ADL impairment in patients with HF may be influenced by country, region, and assessment time. We suggest that more researchers could focus on the changes of ADL impairment in HF patients during different disease periods in different regions and countries.

Prevalence of lateral violence in nurse workplace: a systematic review and meta-analysis.

BACKGROUND: The prevalence of inter-nurse lateral violence (LV) reported in current studies is inconsistent, ranging from 7% to 83%. The purpose of this study is to quantify the prevalence of LV in nurses' workplaces. METHODS: Systematic review and meta-analysis. Cochrane, PubMed, Embase, CINAHL, CNKI and Wanfang databases were searched for relevant studies (up to 27 January 2021). We included cross-sectional, case-control or cohort studies in which both abusers and victims were nurses. Studies that did not provide specific data on abusers were excluded. Stata V.16.0 was used for statistical analysis. Fixed-effect or random-effect model was adopted according to heterogeneity, which was evaluated by Cochran's Q and I2 values. The main indicator was LV prevalence. Sensitivity analysis, subgroup analysis and meta-regression were performed to investigate the sources of heterogeneity. RESULTS: A total of 14 studies with 6124 nurses were included. Further, 13 articles with 5745 nurses were included in the meta-analysis, and the pooled prevalence of LV among nurses was 33.08% (95% CI: 23.41% to 42.75%, p<0.05; I2=99.0%). The remaining one study containing 370 samples reported that the prevalence of inter-nurse LV was 7.92%. Subgroup analysis showed that region, sample size, sampling, study's quality, response rate and publication time might not be the sources of heterogeneity. Meta-regression indicated that sample size had the main influence on model heterogeneity. Egger's test showed the existence of publication bias (p=0.03). DISCUSSION: The prevalence of inter-nurse LV is high in nurse workplace. It is suggested that scholars pay more attention to the cultural differences of inter-nurse LV between regions in the future. This study has the following limitations: there is a lack of studies on LV prevalence in many countries; lack of standard assessment tools; no grey literature was searched.

The Relationship Between Successful Aging and All-Cause Mortality Risk in Older Adults: A Systematic Review and Meta-Analysis of Cohort Studies.

BACKGROUND: This meta-analysis aimed to explore the effect of successful aging (SA) on all-cause mortality risk in older people to provide a theoretical basis for promoting SA. METHODS: PubMed, Embase, CINAHL, CNKI, and WanFang databases (inception to March 4, 2021) were searched for cohort studies to evaluate the relationship between SA and mortality in older people. A random-effects model was used to synthesis hazard ratio and 95% confidence intervals. Quality assessment was performed using the Newcastle-Ottawa scale. All statistical analyses were conducted in STATA 16.0. RESULTS: In total, 21,158 older adults from 10 studies were included in the current systematic review and meta-analysis. The SA group tended to have 50% lower risk of all-cause mortality than the non-SA group (pooled hazard ratio = 0.50, 95% confidence intervals: 0.35-0.65, P < 0.001; I 2 = 58.3%). The risk of all-cause mortality in older people increased by 17% for each unit increment in the healthy aging index (HAI) (I 2 = 0%, P = 0.964). Compared with the reference group (HAI 0-2), older people with HAI 3-4, HAI 5-6, and HAI 7-10 had 1.31-fold, 1.73-fold, and 2.58-fold greater risk of all-cause mortality, respectively. Subgroup analysis did not reveal possible sources of heterogeneity. CONCLUSIONS: This meta-analysis suggests that older adults with SA reduced the risk of all-cause mortality by 50%. However, few interventional studies have been conducted. Therefore, healthcare providers must be aware of the relationship between SA and mortality risk and actively develop intervention methods for helping old people achieve SA.
