Experimental research in environmentally induced hyperthermic older persons: A systematic quantitative literature review mapping the available evidence.

The heat-related health burden is expected to persist and worsen in the coming years due to an aging global population and climate change. Defining the breadth and depth of our understanding of age-related changes in thermoregulation can identify underlying causes and strategies to protect vulnerable individuals from heat. We conducted the first systematic quantitative literature review to provide context to the historical experimental research of healthy older adults - compared to younger adults or unhealthy age matched cases - during exogenous heat strain, focusing on factors that influence thermoregulatory function (e.g. co-morbidities). We identified 4,455 articles, with 147 meeting eligibility criteria. Most studies were conducted in the US (39%), Canada (29%), or Japan (12%), with 71% of the 3,411 participants being male. About 71% of the studies compared younger and older adults, while 34% compared two groups of older adults with and without factors influencing thermoregulation. Key factors included age combined with another factor (23%), underlying biological mechanisms (18%), age independently (15%), influencing health conditions (15%), adaptation potential (12%), environmental conditions (9%), and therapeutic/pharmacological interventions (7%). Our results suggest that controlled experimental research should focus on the age-related changes in thermoregulation in the very old, females, those with overlooked chronic heat-sensitive health conditions (e.g. pulmonary, renal, mental disorders), the impact of multimorbidity, prolonged and cumulative effects of extreme heat, evidence-based policy of control measures (e.g. personal cooling strategies), pharmaceutical interactions, and interventions stimulating protective physiological adaptation. These controlled studies will inform the directions and use of limited resources in ecologically valid fieldwork studies.

An mHealth application for chronic vascular access: Consumer led co-creation.

PURPOSE: Children with chronic and complex health conditions frequently need intravenous devices. The current approach to intravenous device selection, insertion, and monitoring is inconsistent, and healthcare consumers are often negatively affected by siloed health information, and poor future planning. Despite child- and family-centred care being recognised as a pillar of paediatric nursing care, limited implementation for vascular access device planning and management is evident. DESIGN AND METHODS: To address this, we conducted a multi-phased approach to co-create, then evaluate, a mobile health (mHealth) application: IV Passport. Co-creation involved a prioritisation survey, followed by a Passport advisory panel consensus meeting. Following confirmation of the required content and features of the Passport, the mHealth application was designed and content validation achieved via survey. RESULTS: The prioritisation survey yielded recommendations for seven features (e.g., graphical presentations of current/past devices). Content for nine device types (e.g., totally implanted ports) was suggested, each with 10 related items (e.g., insertion site). Content items for device-associated complications, future vascular access plans, and educational resources were also suggested. Following design, the application was released through Apple and Android platforms; and adapted to a paper version. Content validation was established; 100% strongly agreed the application was easy to use; 80% agreed/strongly agreed that they would recommend the Passport to others. CONCLUSION: IV Passport embodies effective child- and family-centred care through consumer co-creation to empower patients and families manage vascular access devices. PRACTICE IMPLICATIONS: IV Passport remains active; and can be utilised across many healthcare settings and patient populations.

An mHealth application for chronic vascular access: A multi-method evaluation.

BACKGROUND: Healthcare consumers require diverse resources to assist their navigation of complex healthcare interactions, however, these resources need to be fit for purpose. AIM: In this study, we evaluated the utility, usability and feasibility of children, families and adults requiring long-term intravenous therapy using a recently developed mobile health application (App), intravenous (IV) Passport. DESIGN: Multi-site, parallel, multi-method, prospective cohort study. METHODS: A multi-site, multi-method study was carried out in 2020-2021, with 46 participants (20 adults, 26 children/family) reporting on their experiences surrounding the use of the IV Passport for up to 6 months. RESULTS: Overall, utility rates were acceptable, with 78.3% (N = 36) using the IV Passport over the follow-up period, with high rates of planned future use for those still active in the project (N = 21; 73%), especially in the child/family cohort (N = 13; 100%). Acceptability rates were high (9/10; IQR 6.5-10), with the IV Passport primarily used for documenting new devices and complications. Thematic analysis revealed three main themes (and multiple subthemes) in the qualitative data: Advocacy for healthcare needs, Complexity of healthcare and App design and functionality. CONCLUSION: Several recommendations were made to improve the end-user experience including 'how to' instructions; and scheduling functionality for routine care. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The IV Passport can be safely and appropriately integrated into healthcare, to support consumers. IMPACT: Patient-/parent-reported feedback suggests the Intravenous Passport is a useful tool for record-keeping, and positive communication between patients/parents, and clinicians. REPORTING METHOD: Not applicable. PATIENT CONTRIBUTION: Consumers reported their experiences surrounding the use of the IV Passport for up to 6 months.
