- Development and validation of a comfort-measuring scale for elderly individuals with chronic conditionsPublication . Marques, Rita; Veludo, Filipa; Sousa, Patrícia Pontífice; Dixe, Maria dos AnjosBackground Ageing is associated with chronic diseases and successive losses, which affect the comfort experienced by the elderly. Hence, in that population, comfort must be viewed as a need, and health care professionals (particularly nurses) should promote it through their interventions. This work aimed at developing a scale to assess comfort in elderly individuals with chronic conditions and determining the aforesaid scale’s psychometric characteristics (validity and reliability), while ascertaining the comfort levels experienced by the participants. Methods Our sample comprised 454 chronically ill elderly individuals, either hospitalized, or in residential care/at home. As regards descriptive statistics, we calculated various summary measures. Validity was appraised via exploratory factor analysis, considering the main components. We performed varimax rotation and factor extraction (in which factors with eigenvalues > 1 were extracted). Reliability was established by calculating internal consistency, using Cronbach’s alpha. For each scale item, we examined the corrected item-test correlation. Additionally, we calculated skewness and kurtosis, also carrying out a confirmatory factor analysis. Results The exploratory factor analysis produced a scale with 38 items and five factors, which fitted the data and explained a variance of 61.355%. The values of the Kaiser-Meyer-Olkin test and the Bartlett’s test (sphericity) were 0.943 and 12055.962, respectively (both with p < 0.001). Our model was substantiated by the confirmatory factor analysis (χ² = 2884.242; df = 660; RMSEA = 0.086; CFI = 0.811; TLI = 0.798; SRMR = 0.066) and the Cronbach’s alpha coefficient was 0.959. The summary measures showed that, overall, the participants experienced good comfort levels (Mean = 3.64; SD = ±0.676), revealing higher comfort levels in the “Spirituality and meaning of life” dimension (Mean = 3.79; SD = ±0.742) and lower comfort levels in the “Normality of life” dimension (Mean = 3.39; SD = ±0.922). Conclusion The scale demonstrated suitable psychometric properties, ensuring its validity and reliability in assessing comfort in elderly individuals with chronic conditions. Its five-factor structure enables a comprehensive evaluation, highlighting key comfort dimensions. These findings support targeted interventions, aiding healthcare professionals in improving care and informing evidence-based practices and health policies to enhance well-being. Implications for nursing and health policy By measuring comfort levels in chronically ill elderly individuals, it is possible to plan/improve the comforting care provided by the involved professionals (namely nurses).

- Multi-scale computer simulations of multi-tubular components manufactured by water-assisted injection mouldingPublication . Pascoal-Faria, Paula; Alves, Nuno; Kamma-Lorger, Christina S.; Marques, Rita; Gomes, Marta; Venkat, Anurag; Silva, Rui; Bastos, Lourenço; Carneiro, Filipa; Cunha, Jorge; Mateus, Artur; Mitchell, Geoffrey R.Water assisted injection moulding is a recent development in the manufacturing technology associated with injection moulding. Injection moulding involved the high pressure injection of molten plastic in to a preformed metal mould which defines the exterior of the shape of the object. Water assisted injection moulding is a variant with an addition step in which water is injected into the mould after its has been filled with molten plastic. The water jet sweeps out the molten plastic in its path to leave a hollow tube in which the interior of the part is defined by the water jet. This technology is used for preparing tubular components for use in the automotive industry and for domestic appliances. We have been developing the technology to prepare parts with branches in the tubing. We have used fine-element simulations to explore the relationship between the process parameters and the subsequent final part. Of course such simulations only serve to define the exterior and interior of the tubular part. It is clear from the outline of the technology above that the molten plastic is subjected to a complex pressure and temperature variation with time which vary across the part and its location within the mould. The specification of the part is in most cases is limited to the geometry and the materials which is used in its preparation, in this case polyamide6 with 30% glass fibre. From the development of plastic processes over the last 50 years we have learnt that the properties of plastic part depend critically on the processing pathway and in particular the timescale for the transformation from molten material to the semi-crystalline solid state. We know from the use of small-angle and wide-angle scattering mapping of the structure and morphology of the multi-tubular components that the level of crystallinity and the extent of preferred orientation varies throughout the part and this may lead to warpage and other geometrical changes in the part during its service life. We have set out to explore how we can use the temperature and pressure variation from the finite element modelling to predict the structure and morphology at different regions in the part in order to be able to establish the parameters which yield a geometrically correct part which is also homogenous in its structure and morphology and hence properties. This paper describes the approach we have taken to make progress with this complex matter of simulations on multiple scales and the application of this technique to realistic automotive tubular components.
- Safety culture in the context of operating room: nurses' perception regarding notification of errors/adverse eventsPublication . Vinagre, Teresa; Marques, RitaThe notification of errors/adverse events is one of the central aspects for the quality of care and patient safety. The purpose of this pilot study is to analyse the safety culture of the operating room in relation to the errors/adverse events and their notification, in the nurses’ perception. It is a quantitative, descriptive-exploratory pilot study. A survey “Nurses’ Perception regarding Notification of Errors/Adverse Events” was applied, consisting of 8 closed questions to an intentional non-probabilistic sample consisting of 43 nurses working in the operating room of a private hospital in Lisbon. The results showed that only 51.2% of the adverse events that caused damage to patients were always notified by the nurses. Of the various adverse events occurred, 60.5% were not reported, justified by “lack of time”. There was also a negative correlation between professional experience and the frequency of error notification (p < .05). The factors referred as those that contributed most to the occurrence of errors were, pressure to work quickly (100.0%), lack of human resources (86.0%), demotivation (86.0%), professional inexperience and hourly overload (83.7%), lack of knowledge (74.4%) and communication failures (65.1%). The perception of Patient Safety was assessed by the majority of participants as “acceptable”. In conclusion, it was evident the reduced notification of adverse events in the operation room so it becomes crucial to focus on the continuous training of health professionals, as well as work on the error, to increase a safety culture with quality.

- Strategies for an effective safety culture and prevent errors in nursing: literature reviewPublication . Vinagre, Teresa; Marques, RitaIntroduction and objective: safety culture is increasingly linked to the quality of care, being crucial for the prevention of errors in health. It is intended to identify which strategies for an effective safety culture and to prevent errors in Nursing. Methodology: Review of the literature. The study includes the analysis of articles found in: CINAHL, MEDLINE, Nursing & Allied Health Collection, Cochrane Database of Systematic Reviews, B-ON e SCIELO. Sample consists of 12 articles. Results: Teamwork and communication were referred in 75% of the studies as key measures; 66.7% reinforce the importance of notification of errors; 58.3% argue that the training/continuous improvement is essential; 33.3% consider the global perception of safety and the importance of trust in leaders as effective methods; 25% alert to the importance of the feedback of errors to health professionals. Conclusion: Teamwork and communication were identified as the most significant strategies, following the notification of errors and training/continuous improvement. In the analyzed articles was identified a direct relationship of the existence of a safety culture with the reduction of adverse events in health care and the need to make the system more secure, instead of trying to change the human condition.
- Validation Testing of the European Portuguese Critical-Care Pain Observation ToolPublication . Marques, Rita; Araújo, Filipa; Fernandes, Marisa; Freitas, José; Dixe, Maria dos Anjos; Gélinas, CélineAim. The study aim was to validate the Portuguese version of the Critical-Care Pain Observation Tool (CPOT) in the critically ill adult population of Portugal. Methods. A prospective, observational cohort study was conducted to evaluate the CPOT in mechanically ventilated patients who were admitted to an intensive care unit. A consecutive sample of 110 patients was observed at rest pre-procedure, during a nociceptive procedure (NP) which includes turning/positioning and endotracheal or tracheal suctioning and 20 min post-procedure. Two raters participated in the data collection. The discriminative validity, criterion validity, convergent validity and inter-rater reliability of the CPOT were examined. Results. The inter-rater reliability was excellent (0.93 ≤ α ≤ 1.00) at rest and fair to moderate (0.39 ≤ α ≤ 0.60) during the NP. The CPOT could discriminate between conditions with higher scores during the NP when compared to CPOT scores at rest (p < 0.001). The optimal CPOT cut-off score was >2, with a sensitivity of 71% and a specificity of 80%, and selfreported pain was the gold standard criterion. Significant correlations (<0.40) were found between CPOT scores, the heart rate and the respiratory rate during the nociceptive procedure. Conclusions. The CPOT appears to be a valid alternative for both ventilated and non-ventilated patients who are unable to communicate.
