Personal protective equipment implementation in healthcare: A scoping review.

BACKGROUND: Adherence to infection prevention and control (IPC) measures, including the proper use of protective personal equipment (PPE), in health care is complex and is influenced by many factors. Isolated interventions do not have the potential to achieve optimal PPE adherence and appropriate provision, leading to incomplete PPE implementation. OBJECTIVE: To map PPE implementation in health care with a focus on its barriers and facilitators. METHODS: A scoping review was conducted across 14 electronic databases using the Joanna Briggs Institute methodology. RESULTS: Seventy-four papers were included in the review. Findings were analyzed and synthesized into categories to match the Consolidated Framework for Implementation Research domains. The content was then synthesized into barriers for PPE implementation and interventions to address them. The main barriers were discomfort in clinical work; shortage, supply and logistics problems; inadequacies in facilities infrastructure, weakness in policies and communication procedures; and health workers' (HW) psychological issues and lack of preparedness. Implementation interventions reported were related to HW wellbeing assurance; work reorganization; IPC protocols; adoption of strategies to improve communication and HW training; and adoption of structural and organizational changes to improve PPE adherence. CONCLUSIONS: PPE implementation, which is critical IPC programs, involves multilevel transdisciplinary complexity. It relies on the development of context-driven implementation strategies to inform and harmonize IPC policy in collaboration with local and international health bodies.

Acute kidney injury caused by venomous animals: inflammatory mechanisms.

Either bites or stings of venomous animals comprise relevant public health problems in tropical countries. Acute kidney injury (AKI) induced by animal toxins is related to worse prognostic and outcomes. Being one the most important pathways to induce AKI following envenoming due to animal toxins, inflammation is an essential biological response that eliminates pathogenic bacteria and repairs tissue after injury. However, direct nephrotoxicity (i.e. apoptotic and necrotic mechanisms of toxins), pigmenturia (i.e. rhabdomyolysis and hemolysis), anaphylactic reactions, and coagulopathies could contribute to the renal injury. All these mechanisms are closely integrated, but inflammation is a distinct process. Hence, it is important to improve our understanding on inflammation mechanisms of these syndromes to provide a promising outlook to reduce morbidity and mortality. This literature review highlights the main scientific evidence of acute kidney injury induced by bites or stings from venomous animals and their inflammatory mechanisms. It included observational, cross-sectional, case-control and cohort human studies available up to December 2019. Descriptors were used according to Medical Subject Headings (MeSH), namely: "Acute kidney injury" or "Venom" and "Inflammation" on Medline/Pubmed and Google Scholar; "Kidney disease" or "Acute kidney injury" on Lilacs and SciELO. The present review evidenced that, among the described forms of renal inflammation, it can occur either directly or indirectly on renal cells by means of intravascular, systemic and endothelial hemolysis, activation of inflammatory pathway, as well as direct action of venom cytotoxic components on kidney structures.
