Background: This study aimed to evaluate burnout in intensive care unit nurses and describe the relationship between burnout dimensions and sociodemographic and professional variables. Methods: A pilot study was carried out with 29 intensive care nurses during the COVID-19 pandemic. The data were collected using an online questionnaire consisting of a sociodemographic characterization and the Maslach Burnout Inventory Human Services Survey. In the comparative statistical analysis, the nonparametric Mann–Whitney and Kruskal–Wallis tests were used (p < 0.05). Results: The Emotional Exhaustion dimension represented an average of 27.9 ± 10.4, and the Personal Fulfillment of 30.8 ± 7.0 was considered high. Regarding Depersonalization, medium-level results (8.1 ± 6.0) were found. There was a prevalence of 41.3% of high levels of burnout. There was no statistically significant difference in the comparison between the three dimensions and sociodemographic and professional variables (p > 0.05). Conclusions: The global results point to high levels of burnout in nurses, with greater expression in the Emotional Exhaustion and Professional Fulfillment domains. There were no differences between groups, demonstrating homogeneity in the team’s level of burnout. The incidence of burnout in this study was higher than that identified in other studies carried out in Portugal with health professionals. This pilot study will allow the defining of strategies for reducing burnout and, consequently, a proposed extension of the study to other organization wards.

Background/Objectives: The common heart failure (HF) symptoms—dyspnea, fatigue, and edema—often prompt emergency visits. Dyspnea notably affects activities of daily living (ADLs), making its assessment crucial for evaluating therapeutic success. This study assesses the reliability and validity of the European Portuguese version of the London Chest Activity of Daily Living (LCADL) scale, originally validated in 2010, to evaluate ADL limitations in patients with HF. Methods: Following international guidelines for translation and cultural adaptation, 46 patients with HF from two cardiology departments were enrolled. The Six Minute Walk Test (6MWT) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were used for construct validity. Results: A significant correlation was found between the results of the 6MWT and the LCADL total score (r = −0.504; p < 0.001) and the LCADL scale and the MLHFQ (r = 0.703; p < 0.001), except for the domestic activities dimension (r = 0.278; p = 0.062). Reliability revealed an α of 0.917. Conclusions: The study presents the validation of the European Portuguese version of the LCADL scale in patients with HF, emphasizing its reliability and cultural appropriateness. The LCADL scale has proven effective in assessing dyspnea-induced limitations in ADLs, and this study expands its utility by suggesting broader clinical setting applications. Future research should explore its adaptability in diverse healthcare settings, potentially enhancing personalized care strategies and patient outcomes. This work underscores the LCADL scale’s role in facilitating more targeted and effective interventions for managing ADL limitations in patients with HF, suggesting a significant impact on clinical practices and patient care management.
