Background: The prevention of catheter-related complications is nowadays an important topic of research. Flushing catheters is considered an important clinical procedure in preventing malfunction and several complications such as phlebitis or infection. Considering the latest guidelines of the Infusion Nurses Society, the flushing should be carried out both pre-and post-drug administration, requiring different syringes (with associated overall increased times of preparation/administration of intravenous medication by nurses, and also increasing the need for manipulation of the venous catheter). Methods/design: A multi-centre, two-arm randomised controlled trial with partially blinded outcome assessment of 146 adult patients. After eligibility analysis and informed consent, participants will receive usual intravenous administration drugs with flushing procedures, with a double-chamber syringe (arm A) or with classic syringes (arm B). The outcomes assessment will be performed on a daily basis by an unblinded ward team, with the same procedures in both groups. Some main outcomes, such as phlebitis and infiltration, will also be evaluated by nurses from a blinded research team and registered once a day. Discussion: The study outlined in this protocol will provide valuable insight regarding the effectiveness and safety of this new medical device. The development of this medical device (dual-chamber syringe, for drug and flush solution) seems to be an important step to facilitate nurses' adoption of good clinical practices in intravenous procedures, reducing catheter manipulations. Trial registration: ClinicalTrials.gov, NCT04046770. Registered 13 August 2019.

Background: Flushing a venous access device is an important procedure to maintain their patency and prevent malfunctioning and complications. An innovative double-chamber syringe was developed, allowing for the assessment of catheter patency, drug delivery and final flush. This study aims to assess the usability of this new device, considering three development stages (concept, semi-functional prototype, functional prototype). Methods: An iterative methodology based on a mix-method design (qualitative and quantitative) enabled the assessment of the devices’ usability by their primary end-users. A usability questionnaire was developed and applied, along with focus groups and individual interviews to nurses. Results: The usability questionnaire integrated 42 items focused on four dimensions (usefulness; ease of use; ease of learning; satisfaction and intention to use). The initial psychometric findings indicate a good internal consistency and the conceptual relevance of the items. The scores seem to be sensitive to the usability evaluation of the medical devices in different stages of product development (with lower values on functional prototype evaluation), and related to nurses’ perceptions about functional and ergonomic characteristics. Conclusions: Quantitative and qualitative data provided a comprehensive overview of the double-chamber syringes’ usability from the nurses’ point of view, informing us of features that must be addressed.

Resumo Objetivo Descrever o processo de construção e validação de uma cartilha educativa sobre atividade sexual de pessoas com lesão medular. Métodos Estudo metodológico em quatro etapas: pesquisa documental em blogs, revisão integrativa, construção da cartilha educativa, validação de conteúdo com 11 juízes, validação de aparência técnica com 3 juízes e validação de aparência com 37 pessoas do público-alvo. Considerou-se o Índice de Validade de Conteúdo (IVC) mínimo de 0,80. Resultados A cartilha apresentou IVC global de 0,91 pelos juízes profissionais de saúde; 0,87 pelos juízes designers gráficos; e 0,94 na validação de aparência pelo público-alvo. Entretanto, os juízes e público-alvo propuseram sugestões de melhorias da cartilha, que foram acatadas e modificadas para versão final do material. Conclusão A cartilha apresentou conteúdo e aparência adequados para promoção da atividade sexual saudável e satisfatória da pessoa com lesão medular.

Musculoskeletal disorders can be significantly disabling, particularly those related to work, when the underlying mechanisms and clinical variables are not well known and understood. Nurses usually remain in standing positions or walk for long periods, thus increasing the risk for the development of musculoskeletal disorders, particularly on the foot, such as plantar fasciitis or edema. This type of disorders is a major cause of sickness, absence from work, and also dropout ratios among nursing students, which contributes to the shortage of nursing professionals. This review will address foot disorders that arise from prolonged standing in nursing professionals and describe the main clinical parameters characterizing them, with exclusions for other health professions or disorders with other identified causes. English, French, Portuguese, and Spanish published studies from 1970 to the current year will be considered. The review will follow the JBI methodology, mainly though the PCC mnemonic, and the reporting guidelines for Scoping Reviews. The search will include main databases and relevant scientific repositories. Two independent reviewers will analyze the titles, abstracts, and full texts. A tool developed by the research team will aid in the data collection.

Background In nursing practice, flushing the catheters pre and post-drug administration is considered an important clinical procedure to prevent complications, and requires the use of several syringes to comply with international standards of care. We envisioned an innovative doublechamber syringe that enables the filling and administration of both solutions. Following current international recommendations, the development of new medical devices should integrate Health Technology Assessment. The Human-centred design is usually used for that assessment purposes, as a method that actively include end-users in the devices development process. Method Application of the Human-Centred Design through the involvement of nurses in the initial stages of the device development in order to accomplish the initial stages of Technology Readiness Level. A multi-method approach was used, including literature/guidelines review, focus groups with end-users and expert panels. Results The involvement of nurses enabled the definition of user requirements and contexts of use, as well as the evaluation of design solutions and prototypes in order to accomplish with usability and ergonomic features of the medical device.
