Background Nurses in intensive care units (ICUs) experience more stressful workplace conditions, making them more vulnerable to high levels of depression compared with those working in other healthcare settings. Objectives This meta‐analysis aimed to estimate the pooled prevalence of depression in ICU nurses. Methods A systematic search was conducted in Medline, EMBASE, CINHO, and Web of Science databases. Studies that reported depression among ICU nurses measured by a validated tool were synthesized using a random‐effects model. Differences in prevalence of depression by study‐level characteristics were estimated using sub‐group analysis. Heterogeneity was investigated using standard Chi‐squared tests and the I2 statistic. Results Data were extracted from 19 cross‐sectional studies (2003‐2020) from 11 countries involving 7196 ICU nurses. The overall pooled prevalence of depression or depressive symptoms among ICU nurses was 24.99% (95% CI, 17.9%‐32.7%) with high between‐study heterogeneity (χ2 = 812, τ2 = 0.03, I2 = 98%, P < .01). Conclusion Depression appears to be common among ICU nurses. Considering its negative impact on the quality of life of staff, patient care, and the overall critical care work environment, effective interventions should be designed and implemented to improve psychological health in this population. Relevance to clinical practice Findings of this review indicate that regular screening for depressive symptoms might be helpful, and access to professional help and supportive care should be provided if necessary.

Objective. To evaluate the level of cardiometabolic index (CMI) to predict the risk of acute exacerbation in patients with stable chronic obstructive pulmonary disease (COPD), and to provide a basis for early identification and intervention of high-risk patients in clinical nursing work. Methods. Patients with stable chronic obstructive pulmonary disease who were admitted to the outpatient department of respiratory medicine in a tertiary hospital or followed up after discharge from January to December 2021 were retrospectively selected. CMI was measured and statistical analysis was performed to determine the optimal threshold for predicting acute exacerbation of chronic obstructive pulmonary disease. Results. A total of 63 patients with chronic obstructive pulmonary disease were enrolled. The median number of episodes in the previous year was 1.00; 44 patients had ≥1 acute exacerbation. The CMI was positively correlated with the frequency of acute exacerbations and the British Medical Research Council (mMRC) score in the previous year, and negatively correlated with the percentage of forced expiratory volume in 1 second to the predicted value (FEV1% PRED). The cut-off point of CMI for predicting acute exacerbations in stable chronic obstructive pulmonary disease patients was 2.05, with a sensitivity of 0.864% and specificity of 0.842%. It is a risk factor for acute exacerbation in COPD patients. Conclusion. CMI can be used as a biological index to predict acute exacerbation in stable COPD patients. Clinical nursing needs to evaluate patients' CMI and provide personalized nursing intervention for patients with CMI≥2.05.

PurposeTo explore the practical value of enteral nutrition care guided by evidence-based concepts in preventing enteral nutritional complications in critically ill neurosurgical patients.MethodsThree hundred critically ill patients from March 2020 to October 2021 from our neurosurgery department were included in the study. Patients were divided into a control group (March to December 2020, n = 150) and a study group (January to October 2021, n = 150) according to the order of their admission. The control group received conventional enteral nutrition care, and the study group received enteral nutrition care based on evidence-based concept guidance. The levels of serum nutritional indicators [hemoglobin (Hb), albumin (ALB), and total protein (TP)], feeding compliance rate, the incidence of complications (gastric retention, bloating, diarrhea, reflux, vomiting, aspiration, stress ulcers, etc.), and prognosis during the observation period were compared between the two groups. The scores of the questionnaire of knowledge, attitude, and practice on nutrition among neurosurgical nurses before and after the implementation of evidence-based care were compared among nursing staff in the study group.ResultsAt 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were lower in both groups than before enrollment in the same group (P &lt; 0.05). At 2 weeks after enrollment, Hb, ALB, and TP levels were higher in both groups than at 1 week after enrollment in the same group (P &lt; 0.05). At 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were higher in the study group than in the control group (P &lt; 0.05). At 7 days after feeding, the feeding compliance rate was higher in the study group (94.67%) than in the control group (70.00%) (P &lt; 0.05). The total complication rate was lower in the study group (8.00%) than in the control group (16.00%) (P &lt; 0.05). The percentage of good prognosis was higher in the study group (34.00%) than in the control group (23.33%) (P &lt; 0.05). After the implementation of evidence-based care, caregivers in the study group scored higher on nutrition knowledge, nutrition attitudes, and nutrition practices than those before the implementation (P &lt; 0.05).ConclusionThe implementation of evidence-based nursing interventions in critically ill neurosurgical patients based on evidence-based concepts is of great clinical value in correcting their nutritional status, preventing enteral nutritional complications, improving prognosis, and enhancing the nutritional knowledge, attitudes, and practices of nursing staff.
