ABSTRACT
BACKGROUND: Sleep disorders are common among patients admitted to intensive care units (ICUs). This study aimed to assess the perceptions of sleep quality, anxiety, depression, and stress reported by ICU patients and the relationships between these perceptions and patient variables. METHODS: This cross-sectional study used consecutive non-probabilistic sampling to select participants. All patients admitted for more than 72 hours of ICU hospitalization at a Portuguese hospital between March and June 2020 were asked to complete the "Richard Campbell Sleep Questionnaire" and "Anxiety, depression, and Stress Assessment Questionnaire." The resulting data were analyzed using descriptive statistics, Pearson's correlation coefficient, Student t-tests for independent samples, and analysis of variance. The significance level for rejecting the null hypothesis was set to α ≤0.05. RESULTS: A total of 52 patients admitted to the ICU for at least 72 hours was recruited. The mean age of the participants was 64 years (standard deviation, 14.6); 32 (61.5%) of the participants were male. Approximately 19% had psychiatric disorders. The prevalence of self-reported poor sleep was higher in women (t[50]=2,147, P=0.037) and in participants with psychiatric problems, although this difference was not statistically significant (t[50]=-0.777, P=0.441). Those who reported having sleep disorders before hospitalization had a worse perception of their sleep. CONCLUSIONS: Sleep quality perception was worse in female ICU patients, those with psychiatric disorders, and those with sleep alterations before hospitalization. Implementing early interventions and designing nonpharmacological techniques to improve sleep quality of ICU patients is essential.
ABSTRACT
AIMS AND OBJECTIVES: To review, synthesise and integrate primary research on the relationship between professional empowerment and evidence-based practice (EBP) in nursing. BACKGROUND: Professional empowerment research exposes an association between empowerment and positive work behaviours and attitudes. Empowerment is associated with nurses' productivity, autonomy and resources. However, implementing evidence into practice is not easy due to barriers to EBP, namely organisational and cultural. Research demonstrating the relationship between professional empowerment and EBP will provide direction for future interventions aimed at the development of an effective healthcare sector. DESIGN: A mixed-methods systematic review, according to the Joanna Briggs Institute approach, with results reported according to PRISMA. The associated checklist for systematic reviews was also used. METHOD: The electronic databases searched for relevant studies included: Medline, Cumulative Nursing and Allied Health Literature (CINAHL), JBI Database of Systematic Reviews and Implementation Reports, and The Cochrane Library; thesis and dissertation databases; and Web pages of reference organisations and Scientific Events programs. Quality assessments, data extraction and analysis were completed on all included studies, according JBI. Thematic analysis was used to synthesise the data. RESULTS: We identified 477 studies. After removing duplicates and reviewing title and abstract following the inclusion and exclusion criteria, 26 papers were evaluated for eligibility. The review included 9 articles. The literature was categorised into three themes: (a) organisational and leadership characteristics, (b) individual characteristics, and (c) outcomes/consequences. CONCLUSION: This review highlights the importance of empowering environments in EBP. A relationship was evident between leadership, organisation, empowerment, individual characteristics and the use and implementation of evidence, resulting in tangible and measurable gains. However, more robust studies are needed. This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42018086414).
