Evaluation of change in emergency care knowledge and skills among front-line healthcare providers in Ukraine with the Basic Emergency Care course: a pretest/post-test study.

OBJECTIVE: Evaluate the change in participant emergency care knowledge and skill confidence after implementation of the WHO-International Committee of the Red Cross (ICRC) Basic Emergency Care (BEC) course. DESIGN: Pretest/post-test quasi-experimental study. SETTING: Mechnikov Hospital in Dnipro, Ukraine. PARTICIPANTS: Seventy-nine participants engaged in the course, of whom 50 (63.3%) completed all assessment tools. The course was open to healthcare providers of any level who assess and treat emergency conditions as part of their practice. The most common participant profession was resident physician (24%), followed by health educator (18%) and prehospital provider (14%). INTERVENTIONS: The 5-day WHO-ICRC BEC course. PRIMARY AND SECONDARY OUTCOME MEASURES: Change in pre-course and post-course knowledge and skill confidence assessments. Open-ended written feedback was collected upon course completion and analysed for common themes. RESULTS: Participant knowledge assessment scores improved from 19 (IQR 15-20) to 22 (IQR 19-23) on a 25-point scale (p<0.001). Participant skill confidence self-assessment scores improved from 2.5 (IQR 2.1-2.8) to 2.9 (IQR 2.5-3.3) on a 4-point scale (p<0.001). The most common positive feedback themes were high-quality teaching and useful skill sessions. The most common constructive feedback themes were translation challenges and request for additional skill session time. CONCLUSIONS: This first implementation of the WHO-ICRC BEC course for front-line healthcare providers in Ukraine was successful and well received by participants. This is also the first report of a BEC implementation outside of Africa and suggests that the course is also effective in the European context, particularly in humanitarian crisis and conflict settings. Future research should evaluate long-term knowledge retention and the impact on patient outcomes. Further iterations should emphasise local language translation and consider expanding clinical skills sessions.

White Paper on Early Critical Care Services in Low Resource Settings.

This White Paper has been formally accepted for support by the International Federation for Emergency Medicine (IFEM) and by the World Federation of Intensive and Critical Care (WFICC), put forth by a multi-specialty group of intensivists and emergency medicine providers from low- and low-middle-income countries (LMICs) and high-income countries (HiCs) with the aim of 1) defining the current state of caring for the critically ill in low-resource settings (LRS) within LMICs and 2) highlighting policy options and recommendations for improving the system-level delivery of early critical care services in LRS. LMICs have a high burden of critical illness and worse patient outcomes than HICs, hence, the focus of this White Paper is on the care of critically ill patients in the early stages of presentation in LMIC settings. In such settings, the provision of early critical care is challenged by a fragmented health system, costs, a health care workforce with limited training, and competing healthcare priorities. Early critical care services are defined as the early interventions that support vital organ function during the initial care provided to the critically ill patient-these interventions can be performed at any point of patient contact and can be delivered across diverse settings in the healthcare system and do not necessitate specialty personnel. Currently, a single "best" care delivery model likely does not exist in LMICs given the heterogeneity in local context; therefore, objective comparisons of quality, efficiency, and cost-effectiveness between varying models are difficult to establish. While limited, there is data to suggest that caring for the critically ill may be cost effective in LMICs, contrary to a widely held belief. Drawing from locally available resources and context, strengthening early critical care services in LRS will require a multi-faceted approach, including three core pillars: education, research, and policy. Education initiatives for physicians, nurses, and allied health staff that focus on protocolized emergency response training can bridge the workforce gap in the short-term; however, each country's current human resources must be evaluated to decide on the duration of training, who should be trained, and using what curriculum. Understanding the burden of critical Illness, best practices for resuscitation, and appropriate quality metrics for different early critical care services implementation models in LMICs are reliant upon strengthening the regional research capacity, therefore, standard documentation systems should be implemented to allow for registry use and quality improvement. Policy efforts at a local, national and international level to strengthen early critical care services should focus on funding the building blocks of early critical care services systems and promoting the right to access early critical care regardless of the patient's geographic or financial barriers. Additionally, national and local policies describing ethical dilemmas involving the withdrawal of life-sustaining care should be developed with broad stakeholder representation based on local cultural beliefs as well as the optimization of limited resources.

IFN-γ production to leishmania antigen supplements the leishmania skin test in identifying exposure to L. braziliensis infection.

BACKGROUND: Cutaneous leishmaniasis due to L. braziliensis (CL) is characterized by a positive delayed type hypersensitivity test (DTH) leishmania skin test (LST) and high IFN-γ production to soluble leishmania antigen (SLA). The LST is used for diagnosis of CL and for identification of individuals exposed to leishmania infection but without disease. The main aim of the present study was to identify markers of exposure to L. braziliensis infection. METHODOLGY/PRINCIPAL FINDINGS: This cohort study enrolled 308 household contacts (HC) of 76 CL index cases. HC had no active or past history of leishmaniasis. For the present cross-sectional study cytokines and chemokines were determined in supernatants of whole blood culture stimulated with SLA. Of the 308 HC, 36 (11.7%) had a positive LST but in these IFN-γ was only detected in 22 (61.1%). Moreover of the 40 HC with evidence of IFN-γ production only 22 (55%) had a positive LST. A total of 54 (17.5%) of 308 HC had specific immune response to SLA. Only a moderate agreement (Kappa = 0.52; 95% CI: 0.36-0.66) was found between LST and IFN-γ production. Moreover while enhancement of CXCL10 in cultures stimulated with SLA was observed in HC with DTH+ and IFN-γ+ and in patients with IFN-γ(+) and DTH(-), no enhancement of this chemokine was observed in supernatants of cells of HC with DTH(+) and IFN-γ(-). CONCLUSIONS/SIGNIFICANCE: This study shows that in addition of LST, the evaluation of antigen specific IFN-γ production should be performed to determine evidence of exposure to leishmania infection. Moreover it suggests that in some HC production of IFN-γ and CXCL10 are performed by cells not involved with DTH reaction.
