Mindfulness-based interventions (MBIs) have been increasingly explored as a potential approach to improving the psychological well-being of FCGs. However, the caregiving burden often results in significant psychological distress, including stress, anxiety, and depression. This systematic review and meta-analysis aims to evaluate the effects of MBIs on the stress, anxiety, and depression of FCGs of cancer patients. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020 guidelines and was registered in PROSPERO. A comprehensive search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Cochrane Library, ERIC, and Google Scholar to identify relevant studies published between 2010 and 2024. Randomized controlled trials (RCTs) and quasi-experimental (QE) studies assessing MBIs' impact on psychological outcomes in FCGs were included. Risk of bias was evaluated using the Joanna Briggs Institute Critical Appraisal Checklists. A total of 10 studies (5 RCTs and 5 QE studies) met the inclusion criteria. Meta-analysis results demonstrated that MBIs significantly reduced anxiety and depression in FCGs of cancer patients compared to usual care or no intervention. Effect sizes varied across studies, with moderate to strong effects observed for anxiety, while depression showed smaller but significant improvements. However, the meta-analysis on stress yielded non-significant results with moderate-to-high heterogeneity. The heterogeneity across studies was moderate, suggesting variability in populations, measurements, intervention formats, duration, and delivery methods. MBIs are effectively improving the psychological well-being of FCGs by reducing anxiety and depression. Given the significant caregiving burden, integrating MBIs into caregiver support programs could enhance their resilience and overall mental health. Future research should explore culturally adapted mindfulness interventions to optimize their applicability in diverse caregiving populations.</p>","PeriodicalId":50677,"journal":{"name":"Clinical Nursing Research","volume":" ","pages":"133-146"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147678431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During IHT, the risk of tangled medical lines is unavoidable. The idea for a novel medical line securement device was inspired by a patient transport nurse due to frustrations and workflow inefficiencies managing tangled medical lines. The study aim was to explore the correlation between the utilization of a single-use securement device to manual or accidental disconnections of medical lines during IHT, and nurses' perception of efficiency, compared to the current practice of no utilization of a securement device. In 2019, a randomized, descriptive, correlational study was conducted on 142 progressive and intensive care hospitalized patients. Study coordinators measured the number of times either IV lines or monitor cords were accidentally or manually disconnected to detangle during or after transportation and the perception of transport efficiency. Results revealed fewer manual disconnections among intervention group compared to the control. Nurses' perception regarding the efficiency between the intervention and control group was statistically significant when the device was utilized to secure the lines and cords during transport. Nurses reported much higher satisfaction rates of transport efficiency when the device was used. This finding showed the device's utility for improving nurse satisfaction during IHT of critically ill patients. Utilization of the medical line securement device may be generalizable across other healthcare settings and disciplines where the complexity of medical lines may exist.</p>","PeriodicalId":50677,"journal":{"name":"Clinical Nursing Research","volume":" ","pages":"193-199"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Morse Fall Scale (MFS) is widely used to assess fall risk within patient settings. Despite its known limitations, it remains a key tool for determining which patients are at risk for falls across healthcare institutions. Veterans with a completed MFS, Care Assessment Need (CAN), and Charlson Comorbidity Index (CCI), admitted to a VHA hospital from July 1, 2020, to June 30, 2022, were included in this retrospective analysis. MFS total scores were captured using electronic health record data from the VHA's national Corporate Data Warehouse. Veterans were identified as having a documented fall through clinical notes. Logistic regression models were used to evaluate the tool's performance at predicting falls. Among 440,771 Veterans, 14,458 (3.3%) had a documented fall during their inpatient stay. On average, those who experienced a fall had higher MFS scores. However, despite this trend, this tool exhibited poor discrimination in the likelihood of falls. Although incorporating patient demographics, the CAN, and CCI into the model improved performance, the model still performed poorly when assessing fall risk. Although the MFS is a required component of clinical workflow in many hospital systems, including VHA, its suboptimal discrimination of fall risk undermines its practical utility. Improved risk models are needed to assess fall risk and from which appropriate fall prevention measures can be initiated.</p>","PeriodicalId":50677,"journal":{"name":"Clinical Nursing Research","volume":" ","pages":"215-224"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13149994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147629094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was a secondary data analysis using data from the study Testing the Effectiveness of the Function Focused Care for Acute Care Study Using the Evidence Integration Triangle (FFC-AC-EIT). A total of 455 residents from 12 nursing homes in two states were included in the study. Sites were randomized to FFC-AC-EIT versus Education Only. The mean age of the participants was 82 years (Standard deviation [<i>SD</i>] = 8.5) and the majority was female (63%), White older adults (65%), married (36%), with high school or more education (81%), and moderate to severe cognitive impairment based on a Saint Louis University Mental Status Exam score of 7.5 (<i>SD</i> = 6.0). Overall, on admission, 17% were on an antipsychotic medication, at discharge, this increased to 21%, and at 1 month, it decreased to 19%.

Our objective was to examine associations among oxidative stress markers, telomere length, clinical characteristics, and PICS-related outcomes in mechanically ventilated ICU survivors. A cross-sectional study design was used. Blood samples were collected at two timepoints: study enrollment and within 48 hr of ICU discharge. PICS-related outcome measures were assessed within 48 hr of ICU discharge. Oxidative stress markers-including plasma protein carbonyls, vitamin C, reduced-to-oxidized glutathione ratio (GSH:GSSG), and total antioxidant capacity (TAC)-were quantified via ELISA. Three oxidative stress indices were calculated: vitamin C/GSH:GSSG, TAC/GSH:GSSG, and protein carbonyls/GSH:GSSG. Telomere length was determined using RT-qPCR. Clinical data included APACHE III and SOFA scores, ICU and hospital length of stay (LOS), and duration of mechanical ventilation. PICS-related outcomes included grip and foot strength, National Institutes of Health (NIH) Toolbox Cognition and Emotion assessments, and the Connor-Davidson Resilience Scale. Pearson's correlations were performed. Twenty-one participants were included in the final analysis. Plasma antioxidant status positively correlated with muscle strength and psychological resilience. Elevated plasma oxidant levels were associated with poorer cognitive outcomes. ICU LOS and duration of mechanical ventilation negatively correlated with muscle strength and cognitive performance. No significant correlations were observed between telomere length changes and PICS-related outcomes. Oxidative stress during acute critical illness may impede recovery and contribute to PICS.
