Abstract: class="Pa2" strong Background /strong class="Pa2" To guide their care paramedics routinely rely upon two assessment and treatment algorithms, known as the primary survey and the secondary survey. No clear consensus of the concepts (assessments and interventions) that are, or should be, included in these algorithms exist internationally. class="Pa2" strong Methods /strong class="Pa2" This paper evaluated Australasian paramedic clinical practice guidelines (CPGs), as well as six other international paramedic CPGs (USA, Ireland, UK, South Africa, Qatar, and the United Arab Emirates) in order to identify which concepts are currently described in best-practice recommendations for paramedics. The authors also contributed concepts that they felt were important additions based on their experience as veteran paramedics and paramedic educators. class="Pa2" strong Results /strong class="Pa2" The resulting amalgamation of concepts identified in each term was then formed into two mnemonics which, together sequentially list approximately 100 specific clinical concepts that paramedics routinely consider in their care of patients. We describe these as the “International Paramedic Primary and Secondary Surveys”. class="Pa2" strong Conclusion /strong class="Pa2" The primary and secondary surveys presented in this paper represent an evidence-based guide to the best practice in conducting a primary and secondary survey in the paramedic context. Findings will be of use to paramedics, paramedic students, and other clinicians working in remote or isolated practices.

Abstract: To identify the epidemiological patterns of pediatric out-of-hospital cardiac arrests (OHCA) in Queensland, Australia and to investigate associations between patient variables and prehospital outcome. Included were pediatric (>4 days-18 years) OHCA patients attended by paramedics in the state of Queensland (Australia) between January 2009 and December 2019. Patient and arrest characteristics were described. Factors associated with return of spontaneous circulation (ROSC) on hospital arrival were investigated. A total of 1,612 pediatric patients were included 611 were deceased prior to paramedic arrival and 1,001 received resuscitation attempts by paramedics. Approximately one quarter (26.8%) of resuscitation-attempted patients achieved ROSC on hospital arrival. Most arrests (49.7%) were due to medical causes. Arrests due to trauma had the lowest rate of ROSC on hospital arrival (9.6%), whereas those due to drug overdose had the highest rate (40%). Patients in rural areas had a lower rate of ROSC on hospital arrival than those in metropolitan areas (20.7% vs 32.5%, p < 0.001). The median response interval to all OHCA patients was 8 minutes. Trauma was considerably more prevalent in rural areas than in metropolitan areas, while all other etiologies were comparable. Older pediatric age groups had higher rates of ROSC on hospital arrival than infants, particularly early adolescents (39.4% vs. 14.9%, p = 0.001). Etiology, age, bystander witness, shockable initial rhythm, and geographic locality factors were independently associated with ROSC on hospital arrival. Approximately a quarter of pediatric prehospital OHCA achieved ROSC on hospital arrival. Prehospital outcome differs according to patient cohort and is associated with erse patient demographic variables.

Abstract: Ponds are often identified by their small size and shallow depths, but the lack of a universal evidence-based definition h ers science and weakens legal protection. Here, we compile existing pond definitions, compare ecosystem metrics (e.g., metabolism, nutrient concentrations, and gas fluxes) among ponds, wetlands, and lakes, and propose an evidence-based pond definition. Compiled definitions often mentioned surface area and depth, but were largely qualitative and variable. Government legislation rarely defined ponds, despite commonly using the term. Ponds, as defined in published studies, varied in origin and hydroperiod and were often distinct from lakes and wetlands in water chemistry. We also compared how ecosystem metrics related to three variables often seen in waterbody definitions: waterbody size, maximum depth, and emergent vegetation cover. Most ecosystem metrics (e.g., water chemistry, gas fluxes, and metabolism) exhibited nonlinear relationships with these variables, with average threshold changes at 3.7 ± 1.8 ha (median: 1.5 ha) in surface area, 5.8 ± 2.5 m (median: 5.2 m) in depth, and 13.4 ± 6.3% (median: 8.2%) emergent vegetation cover. We use this evidence and prior definitions to define ponds as waterbodies that are small ( 5 ha), shallow ( 5 m), with 30% emergent vegetation and we highlight areas for further study near these boundaries. This definition will inform the science, policy, and management of globally abundant and ecologically significant pond ecosystems.
