- Effectiveness of A Nurse-Led Multimodal Intervention in Preventing Blood Culture Contamination: A Before-and-After StudyPublication . Filipe, Susana; Martins, Teresa; Costa, Paulo Santos; Santos, Filipe Paiva; Castilho, Amélia; Bastos, CelesteBlood culture is crucial for accurate and timely bacteremia diagnosis and guide antibiotic therapy. However, during culture sampling, contamination can occur, resulting in misdiagnosis, unnecessary antibiotic exposure, and prolonged hospitalization. This before-and-after intervention study aimed to evaluate the effectiveness of a multimodal intervention in preventing blood culture contamination. The study was conducted in a 170-bed hospital in Portugal and included a total of 23,566 blood cultures. Contamination rates were assessed in two phases: Phase 1 (before intervention, month 0) included 10,928 cultures, and Phase 2 (after intervention, month 6) included 12,638 cultures. During the study period, a multimodal intervention targeting the nursing staff was implemented, consisting of training actions, guideline updates, regular data monitoring and feedback, and introduction of a blood culture pack. Following the intervention, blood culture contamination decreased from 6.8% (Phase 1) to 3.9% (Phase 2). A comparative analysis revealed that the risk of contamination before the intervention was nearly four times higher in first culture, OR = 3.97 (CI 2.86–5.49). Our findings suggest that the multimodal intervention enhanced nurses’ adherence to recommended practices, resulting in a reduced risk of blood culture contamination, earlier identification of infectious agents, and improved accuracy of antibiotic therapy.
- Translation, cultural adaptation, and validation of the Nurse Self-Concept Questionnaire (NSCQ) for Portuguese nursing studentsPublication . Almeida, Inês F.; Bernardes, Rafael A.; Sousa, Liliana B.; Costa, Paulo Santos; Ventura, Filipa; Rosa, AmorimBackground: The professional self-concept of nursing students significantly influences their attitude and identity within the profession, ultimately impacting their mental health and overall well-being. Recent evidence underscores the importance of assessing students' professional self-concept to prevent adverse outcomes such as burnout and stress. Since there are currently no validated instruments available in Portugal for this purpose, our objective was to translate, adapt, and validate the Nurse Self-Concept Questionnaire (NSCQ) with nursing students in Portugal. Methods: A two-phase research study with a non-probabilistic sample of 216 undergraduate nursing students, using the QualtricsXM electronic platform for data collection. An exploratory factor analysis was performed to verify the validity of the theoretical construct and its internal consistency. Cronbach's alpha was calculated, and a confirmatory factor analysis was performed to assess the model fit. Results: The final instrument, designated as Questionário de Autoconceito dos/as Enfermeiros/as (Pt - NSCQ), is composed of 24 items distributed across five dimensions: "General self-concept", "Staff relations", "Leadership", "Communication-care" and "Knowledge", which explain 67.71% of the total variance. All dimensions and the global scale revealed good internal consistency values, ranging from 0.775 to 0.927. The resulting factorial structure is coherent with the theoretical framework. Conclusion: The Pt - NSCQ proved to be a valid and reliable instrument to assess Portuguese nursing students' professional self-concept. Future studies should be carried out on larger samples and different educational contexts, aligned with the importance to ensure the continuity of the psychometric analysis of the instrument.
