Dimensions of Critical Care Nursing最新文献

The term "system well-being" can move forward a new vision, meaning the result coming from the addition of the well-being of persons belonging to different institutions and organizations, which are all parts of the "health care system." Beginning with this "new definition," with the aim of analyzing the multifaceted issues related to nurses' well-being, we could use the "classical nursing metaparadigm" composed of 4 concepts: "health," "nursing," "environment," and "person." We briefly describe this conceptual map and provide some focused suggestions for further reflection on topics such as physical and psychological well-being, economic gain and career opportunities, work climate, burnout, low job satisfaction, moral distress, compassion fatigue, and a joyful work environment. This view may help organizations to focus on interventions to prevent or eliminate stress, which may be more proactive and effective than interventions to manage stress. Moreover, it offers a multidimensional map to analyze the different aspects influencing the well-being issue, keeping in mind that a concrete solution can be obtained only if all the components of health care systems and society do their part. Some solutions proposed by authors and organizations to increase nurses' well-being are mindfulness based, such as meditation, yoga, acupuncture, gratitude, journaling, choirs, coaching, workload reduction, job crafting, and peer networks. Other reflections on work organization, expected professional behaviors, nurses' retention, and education should be added to the discussion on this multidimensional issue.

Introduction: It is important to understand the concept of comfort as a whole to build an assistance intervention plan that meets the person's needs. Therefore, it is necessary to monitor and assess the person's sleep by considering the surrounding environment, to provide a comfortable environment that is quiet and provides privacy, especially in contexts of difficult management of environmental factors in the approach to the person in critical condition.

Objectives: The aims of this study were to map the nursing interventions that promote sleep-promoting environmental comfort in critically ill people and identify the instruments to assess sleep in critically ill people.

Methods: This is a scoping review based on the methodological strategy of the Joanna Briggs Institute for Scoping Reviews. The search was conducted on February 17 and 18, 2022, in the databases CINAHL, Cochrane Library Plus, PubMed, JBI Evidence Synthesis, SciELO, DANS Easy Archive, RCAAP, and DART-Europe using the Boolean phrase search strategy: "Hospital Emergency Service" OR "Critical Care" AND "Sleep" NOT "Children" AND Nurs*. We included all studies, conducted in any contextual setting, in Portuguese, English, or Spanish, on adult patients with acute and/or critical illness in intensive care and/or emergency units, which addressed nursing interventions that contribute to environmental comfort and promote sleep. Studies on pregnant or puerperal women, persons with psychiatric disorders, and those at the end of life or in palliative care were excluded.

Results: Twenty-one articles were included in this scoping review. Three categories of nursing interventions emerged: person centered (14 interventions), environment centered (37 interventions), and nurse role centered (45 interventions). Three categories of instruments for sleep assessment emerged, in particular: quality of sleep (12 instruments), environmental effects on a night's sleep (2 instruments), and influence on sleep practices in the intensive care unit (1 instrument).

Discussion: The use of instruments to monitor comfort and sleep allows for an accurate assessment of the impact of nurses' intervention focusing on sleep-promoting interventions aimed at comfort, for an improvement of sleep in critically ill patients.

Conclusion: The interpretation of the content makes it clear that how critically ill patients in different contexts experience the environmental context positively or negatively conditions their comfort. In this sense, it is essential to reflect on these measures as a team so that everyone can apply them.

Background: Self-efficacy is an important factor associated with healthy lifestyle changes in heart failure treatment. Functional capacity testing of heart failure patients (HFPs) can stratify prognosis. Reduced functional capacities in HFPs are linked to a poor heart failure prognosis. Limited research has examined the potential relationship between self-efficacy and functional capacity.

Aim: The aims of this study were to assess self-efficacy level and functional capacity among HFPs after hospitalization, and examine whether there is a relationship between them.

Methods: A descriptive correlational design was used. A convenience sample of 220 HFPs was recruited from 2 hospitals in Jordan. The Arabic version of Cardiac Self-Efficacy Questionnaire was used to assess self-efficacy, the 6-Minute Walking Test (6-MWT) was used to assess functional capacity, and the Borg rating of perceived exertion scale (Borg Scale) was used to assess exertion during 6-MWT.

Result: The sample included 46.8% male (n = 103) and 53.2% female (n = 117). The mean age was 52.66 ± 8.91 years. Most of the HFPs were categorized based on New York Heart Association classification as class I, 35.9% (n = 79), and class II, 41.4% (n = 91). The mean ejection fraction was 41.46 ± 9.44. The global self-efficacy was moderate (32.98 ± 9.92), and the mean score for the 6-MWT was 494.35 ± 143.37. The Borg Scale mean was 10.94 ± 3.34. In addition, there was a positive relationship between self-efficacy and 6-MWT (r = 0.63, n = 220, P = .01).

Conclusion: This study provides baseline data for further research on treatment of HFPs, and the development of evidence-based tailored health interventions to maintain and improve self-efficacy and functional capacity among these service users. Moreover, replicated researches can test the study results considering different methodologies, such as using objective functional capacity tool and longer follow-up periods.

Aim: The aim of this study was to examine the practices and knowledge levels of nurses regarding enteral nutrition interventions in intensive care unit patients in terms of evidence.

Method: This cross-sectional study was conducted in 2 hospitals between May and August 2021. A total of 136 nurses working in the intensive care units of the hospitals completed online questionnaires including demographic characteristics and questions about enteral nutrition.

Results: According to the nurses' knowledge level about the indication of enteral nutrition formulas, the following were incorrect or incomplete: their knowledge about transition to parenteral nutrition in case of nutritional contraindications, what to do when the amount of gastric residual volume in tolerance is >500 mL every 6 hours, the conditions for starting enteral nutrition, and which formulas are appropriate to use. Regarding their knowledge about enteral feeding tubes/sets, their knowledge about radiologic imaging after tube placement, measurement of gastric pH level, and marking the tube location was insufficient. Differently, the correct answer percentages of the nurses in 11 of the 13 questions regarding the principles of enteral nutrition practice were above 70%.

Conclusion: Nurses had adequate knowledge of the principles of enteral nutrition practice, but their knowledge of the indication of enteral nutrition formulas and the evidence for enteral feeding tubes/sets varied. The results showed that nurses need to gain information about the indication of enteral nutrition formulas and evidence related to enteral feeding tubes/sets.

Background: Opportunities for communication and participation in decision making are limited for critically ill patients, but family members serving as surrogates enable empowerment of these patients.

Objective: The aim of this study was to explore family members' engagement in symptom communication in the intensive care unit.

Methods: A qualitative descriptive design using fieldwork methodology with triangulation of participant observation and individual interviews was conducted. Nine mechanically ventilated patients were observed in interaction with family members and clinicians in the intensive care unit. Six of the observed patients, 6 family members, and 9 clinicians were interviewed after participant observation. Field notes and transcripts were analyzed using Braun and Clarke's method of thematic analysis.

Results: Family members engaged actively in symptom communication, assessment, and management, and there were barriers and facilitators to family engagement. Three main themes and 9 subthemes describing family engagement emerged: (1) intermediary role (recognize and report symptoms, provide patient information, and assist in communication), (2) independent role (provide familiarity, manage symptoms, and promote patient communication), and (3) conditions for family engagement (intensive care unit environment, relationship with the patient, and patient preferences).

Discussion: Family members have unique knowledge of the patient that differs from and complement the competence of the staff, and might contribute to improved symptom communication. Future research should examine how family members can contribute to symptom communication, assessment, and management.

Background: Health care professionals underestimate the recognition of delirium in emergency departments (EDs). In these settings, between 57% and 83% of cases of delirium go undetected. When delirium occurs, it causes an increase in the length of hospitalization, readmissions within 30 days, and mortality. No studies were carried out in Italy to assess the prevalence of delirium among elders in EDs.

Objectives: The primary goal of the study was to evaluate the prevalence of the risk of delirium in people 65 years and older hospitalized in the ED for a minimum of 8 hours. The study's secondary goal was to identify the variables that influenced the risk of delirium.

Method: A multicenter cross-sectional study was conducted in 2 EDs. The risk of delirium was assessed using the delirium screening tool 4 A's test. One hundred patients were enrolled. Data collection took place from June 28 to August 31, 2022.

Results: The risk of delirium was detected in 29% of the sample, whereas the risk of cognitive impairment was 13%. The use of psychotropic drugs increased the risk of delirium by 11.8 times (odds ratio [OR], 11.80; P = .003). Bed confinement increased the risk by 4.3 times (OR, 4.31; P = .009). Being dehydrated increased the risk of onset by 4.6 times (OR, 4.62; P = .010). Having dementia increased the risk of delirium manifestation by 4.4 times (OR, 4.35; P = .021).

Discussion: The risk of delirium was detected in a considerable portion of the sample. The results of this study can be used by health care professionals to implement preventive measures as well as support clinical judgment and establish priorities of care for patients at risk of developing delirium.

Background/introduction: Critically ill older adults are profoundly inactive while in the intensive care unit (ICU), and this inactivity persists after discharge from the ICU. Older ICU survivors who were mechanically ventilated are at high risk for post-ICU cognitive impairment.

Objectives/aims: The present study examined the relationship between the ratio of daytime to nighttime activity and executive function in older ICU survivors.

Methods: This was a secondary analysis of pooled data from 2 primary studies of older adults who were functionally independent prior to hospitalization, mechanically ventilated while in ICU, and within 24 to 48 hours post-ICU discharge. Actigraphy recorded daytime activity (mean activity counts per minute, 6 am to 9:59 pm) and nighttime activity (mean activity counts per minute, 10 pm to 5:59 am). A daytime-to-nighttime activity ratio was calculated by dividing daytime activity by nighttime activity. The NIH Toolbox Dimensional Change Card Sort Test assessed cognitive flexibility (DCCST: fully corrected T score). Multivariate regression examined the association between the daytime-to-nighttime activity ratio and DCCST scores, adjusting for 2 covariates (age in years and NIH Toolbox Grip Strength fully corrected T score).

Results: The mean daytime-to-nighttime activity ratio was 2.10 ± 1.17 (interquartile range, 1.42). Ratios for 6 participants (13.6%) were less than 1, revealing higher activity during nighttime hours rather than daytime hours. Higher daytime-to-nighttime ratios were associated with better DCCST scores (β = .364, P = .005).

Conclusions: The proportion of daytime activity versus nighttime activity was considerably low, indicating severe alterations in the rest/activity cycle. Higher daytime-to-nighttime activity ratios were associated with better executive function scores, suggesting that assessment of daytime activity could identify at-risk older ICU survivors during the early post-ICU transition period. Promotion of daytime activity and nighttime sleep may accelerate recovery and improve cognitive function.
