Performance of a Chemical Heat Blanket in Dry, Damp, and Wet Conditions Inside a Mountain Rescue Hypothermia Wrap.

INTRODUCTION: Casualties with accidental hypothermia are evacuated using multilayer wraps, typically including a chemical heat blanket (CHB), a vapor barrier, and an insulating outer bag. We investigated CHB performance against dry, damp, and wet fabric, in a multilayer wrap, in response to a case report indicating diminished performance when wet. METHODS: We wrapped a torso manikin in a base layer, CHB, vapor barrier, casualty bag, and vacuum mattress, recording CHB panel temperatures at intervals of up to 7 h. Experimental conditions were dry, damp, and wet clothing, with 2 blankets tested in each condition. We subsequently used a forward-looking infrared camera to assess whether the panels heated evenly and heat flux sensors to quantify heat transfer across 2 dry, 1 damp, and 1 wet fleece under CHB panels. RESULTS: Chemical heat blankets maintained heat output for >7 h inside the wraps. Median (IQR) panel steady state temperatures were 52°C (39-56°C) against dry fleece, 41°C (36-45°C) against damp fleece, and 30°C (29-33°C) against wet fleece. Peak panel temperature was 67°C. The heat flux results indicated that CHBs generated similar quantities of heat in dry and damp conditions, as the lower temperatures were compensated by more efficient transfer of heat across the moist clothing layer. Chemical heat blanket heat output was diminished in wet conditions. CONCLUSIONS: Rescuers should cut off saturated clothing in a protected environment before wrapping casualties, but damp clothing need not be removed. Because of the high peak temperatures recorded on the surfaces of CHBs, they should not be placed directly against skin, and compression straps should not be placed directly over CHBs.

Advanced practice nurse roles in Europe: Implementation challenges, progress and lessons learnt.

BACKGROUND: Advanced practice nursing (APN) roles offer improved access to care and increased quality and more timely care. Despite the advantages of APN roles, there is a disparity between European countries when it comes to implementing APN roles. AIM: To explore the implementation of APN roles in a range of European countries and to explore what factors facilitate or hinder the implementation of these roles. METHODS: A case study evaluation of the process of implementing APN roles. The sample included four countries where APN roles were well developed (Ireland, Spain, Norway and the United Kingdom) and four where APN roles were implemented (Estonia, Slovenia, Cyprus and Romania). Interviews were conducted with key informants (n = 28) from government departments, regulatory bodies, nursing associations and universities. The consolidated criteria for reporting qualitative research (CPREQ) has been used throughout. LIMITATIONS: The small number of countries when considering the size of the region and key informants representing the view of only three to four people in each country. RESULTS: Four themes were identified, including the rationale for the development of the roles, influence, the evolutionary nature of role development and evidence. The data also revealed a mismatch between the perceptions of how the roles develop among the different countries in the early stages of implementation. CONCLUSION: Successful role implementation is dependent upon a tripartite approach between managers, practitioners and educators. An evolutionary approach to role development was used. Regulation and policy come later on in the process of implementation. IMPLICATIONS FOR NURSING POLICY: APN policy should be based on patient needs rather than on the workforce or professional imperatives. The process of implementation can take 15-20 years in total. Recognising the importance of the relationships between service managers and educators is key to the early development of these roles.

Collaborative strategic initiative between a university and hospital network group: Advanced nurse/midwife practice forum.

BACKGROUND: The Faculty of Nursing and Midwifery, one of a few nursing and midwifery faculties worldwide, was established in 1974 by Ms Mary Frances Crowley, for postgraduate nursing education, and is situated within the Royal College of Surgeons in Ireland, University of Medicine and Health Sciences. The RCSI operates through a network group of university hospitals: Beaumont, Connolly, Drogheda, Cavan, Monaghan and the Rotunda. Combined these hospitals have 120 registered and candidate ANP/AMPs and caters for general, psychiatric, children and maternity patients/clients. The drive to establish the forum between the faculty and the six Dublin hospitals was to build capacity among advanced nurse practitioners and advanced midwife practitioners (ANP/AMPs) who are seen as intelligent consumers of evidence-based research and safe practice. The SCAPE report identified research as the single domain that was underdeveloped within the ANP role, in the study exploring the role of ANPs and CNSs. Latterly, the Nursing and Midwifery Board of Ireland highlighted research as a vital component of the ANP/AMP role in its standards for advanced nurse and midwife practice. The faculty acted collaboratively to introduce an ANP/AMP forum to support advanced practitioners working in the university hospital group in their education and professional development, support the expansion of their knowledge base through practice-based enquiry and research and act as a conduit for interactions between ANPs/AMPs by keeping them up to date with practice and research. METHODS: The Initiation phase was undertaken through a survey of needs; Implementation phase by extensive literature review and research-based newsletters sent to individuals by the forum coordinator; and the Evaluation phase through focus groups.

Qualitative assessment of venues for purposive sampling of hard-to-reach youth: an illustration in a Latino community.

BACKGROUND: Latino youth suffer disproportionately from unintended pregnancy and sexually transmitted infections (STIs), but studies of the social context of their sexual behaviors are lacking. GOAL: Our qualitative assessment of recruitment venues in a Latino neighborhood had 3 objectives: to identify venues where youth at risk of unintended pregnancy and STIs could be found; to describe different youth "crowds"; and to investigate how and where youth meet their sex partners. STUDY DESIGN: We conducted ethnographic interviews with 62 youth recruited primarily from street sites. Mapping of venues was conducted with Map-Info. RESULTS: Youth crowds included the Regulars, gang-related crowds, street-economy affiliated crowds, and female crowds. Maps demonstrated the dominance of the venues in the Mission by gang members. Street sites are important venues for meeting sexual partners. CONCLUSION: The qualitative assessment produced insights and hypotheses that can contribute to the planning of research, outreach, testing, and interventions with Latino youth.
