A Complex Intervention to Minimize Medication Error by Nurses in Intensive Care...
Coelho, Fábio; Furtado, Luís; Tavares, Márcio; Pereira, Joana SousaBackground/Objectives: Medication errors are the most frequent and critical issues in healthcare settings, often leading to worsened clinical outcomes, increased treatment costs, extended hospital stays, and heightened mortality and morbidity rates. These errors are particularly prevalent in intensive care units (ICUs), where the complexity and critical nature of the care elevate the risks. Nurses play a pivota...
Exploring professional practice environments and organisational context factors...
Furtado, Luís; Coelho, Fábio; Mendonça, Natália; Soares, Hélia; Gomes, Luís; Sousa, Joana Pereira; Duarte, Hugo; Costeira, Cristina; Santos, CátiaThis scoping review, conducted within the Joanna Briggs Institute (JBI) framework, analysed the recent literature (January 2018 to March 2023) addressing factors inherent to professional practice environments and organisational contexts influencing nurses’ adoption of evidence-based practice (EBP). This review included studies involving nurses regardless of sector, practice setting, and scope of practice. A sys...
Delphi technique on nursing competence studies: a scoping review
Furtado, Luís; Coelho, Fábio; Pina, Sara; Ganito, Cátia; Araújo, Beatriz; Ferrito, CândidaThis scoping review was conducted under the Joanna Briggs Institute (JBI) framework. It included primary studies published until 30 April 2023, obtained through a systematic search across PubMed, Web of Science, CINAHL, and MEDLINE databases. The review focused on primary studies that used the Delphi technique in nursing competence research, especially those related to defining core competency frameworks and de...
Loom: a closed-box disaggregated database system
Coelho, Fábio; Alonso, Ana; Ferreira, Luis; Pereira, José; Oliveira, Rui Carlos Mendes deCloud native database systems provide highly available and scalable services as part of cloud platforms by transparently replicating and partitioning data across automatically managed resources. Some systems, such as Google Spanner, are designed and implemented from scratch. Others, such as Amazon Aurora, derive from traditional database systems for better compatibility but disaggregate storage to cloud service...
AIDA-DB: a data management architecture for the edge and cloud continuum
Faria, Nuno; Costa, Daniel; Pereira, José; Vilaça, Ricardo Manuel Pereira; Ferreira, Luís; Coelho, FábioThere is an increasing demand for stateful edge computing for both complex Virtual Network Functions (VNFs) and application services in emerging 5G networks. Managing a mutable persistent state in the edge does however bring new architectural, performance, and dependability challenges. Not only it has to be integrated with existing cloud-based systems, but also cope with both operational and analytical workload...
Positive Mental Health and Mental Health Literacy of Informal Caregivers: A Sco...
Andrade, Carmen; Tavares, Márcio; Soares, Hélia; Coelho, Fábio; Tomás, CatarinaPositive mental health and mental health literacy are two main concepts to ensure an individual and social state of mental health and well-being. A scoping review of the scientific literature published in the field of health sciences was conducted to identify the relationship between mental health literacy and the positive mental health of family caregivers. A research expression was used to search for articles...
Minha: large-scale distributed systems testing made practical
Machado, Nuno; Maia, Francisco; Neves, Francisco Nuno Teixeira; Coelho, Fábio; Pereira, JoséTesting large-scale distributed system software is still far from practical as the sheer scale needed and the inherent non-determinism make it very expensive to deploy and use realistically large environments, even with cloud computing and state-of-the-art automation. Moreover, observing global states without disturbing the system under test is itself difficult. This is particularly troubling as the gap between...
Self-tunable DBMS replication with reinforcement learning
Ferreira, Luís; Coelho, Fábio; Pereira, JoséFault-tolerance is a core feature in distributed database systems, particularly the ones deployed in cloud environments. The dependability of these systems often relies in middleware components that abstract the DBMS logic from the replication itself. The highly configurable nature of these systems makes their throughput very dependent on the correct tuning for a given workload. Given the high complexity involv...
Towards intra-datacentre high-availability in CloudDBAppliance
Ferreira, Luis; Coelho, Fábio; Alonso, Ana Nunes; Pereira, JoséIn the context of the CloudDBAppliance (CDBA) project, fault tolerance and high-availability are provided in layers: within each appliance, within a data centre and between data centres. This paper presents the proposed replication architecture for providing fault tolerance and high availability within a data centre. This layer configuration, along with specific deployment constraints require a custom replicati...
Permeability of the implanted central catheter - A literature review
Ramada, Diana; Coelho, Fábio; Guilherme, Denise; Marques, PauloTotally implantable catheter (CVCTI) is a type of central venous catheter that becomes an essential resource because it increases the options available for intravenous therapy. Its handling is not free of complications. There are many controversies about the most appropriate solution to maintain its permeability. In this context, it was intended to determine the effectiveness of a heparin solution compared to s...
