Medication communication between nurses and doctors for paediatric acute care: An ethnographic study
AIMS AND OBJECTIVES: To examine how communication between nurses and doctors occurred for managing medications in inpatient paediatric settings. BACKGROUND: Communication between health professionals influences medication incidents' occurrence and safe care. DESIGN: An ethnographic study was undertaken. METHODS: Semi-structured interviews, observations and focus groups were conducted in three clinical areas of an Australian tertiary paediatric hospital. Data were transcribed verbatim and thematically analysed using the Medication Communication Model. RESULTS: The actual communication act revealed professionals' commitment to effective medication management and the influence of professional identities on medication communication. Nurses and doctors were dedicated to providing safe, effective medication therapy for children, within their scope of practice and perceived role responsibilities. Most nurses and junior doctors used tentative language in their communication while senior doctors tended to use direct language. Irrespective of language style, nurses actively engaged with doctors to promote patients' needs. Yet, the medical hierarchical structure, staffing and attendant expectations influenced communication for medication management, causing frustration among nurses and doctors. Doctors' lack of verbal communication of documented changes to medication orders particularly troubled nurses. Nurses persisted in their efforts to acquire appropriate orders for safe medication administration to paediatric patients. CONCLUSIONS: Collaborative practice between nurses and doctors involved complex, symbiotic relationships. Their dedication to providing safe medication therapy to paediatric patients facilitated effective medication management. At times, shortcomings in inter-disciplinary communication impacted on potential and actual medication incidents. RELEVANCE TO CLINICAL PRACTICE: Understanding of the complexities affecting medication communication between nurses and doctors helps to ensure inter-professional respect for each other's roles and inherent demands. Interdisciplinary education delivered in health care organisations would facilitate greater clarity in communication related to medications. Encouraging the use of concise, clear words in communication would help to promote improved understanding between parties, and accuracy and efficacy of medication management.

Antiferromagnetic Order in MnO Spherical Nanoparticles
We have performed unpolarized and polarized neutron diffraction experiments
on monodisperse 8 nm and 13 nm antiferromagnetic MnO nanoparticles. For the 8
nm sample, the antiferromagnetic transition temperature (114 K) is
suppressed compared to the bulk material (119 K) while for the 13 nm sample
(120 K) is comparable to the bulk. The neutron diffraction data of the
nanoparticles is well described using the bulk MnO magnetic structure but with
a substantially reduced average magnetic moment of 4.20.3 /Mn for
the 8 nm sample and 3.90.2 /Mn for the 13 nm sample. An analysis of
the polarized neutron data on both samples shows that in an individual MnO
nanoparticle about 80 of Mn ions order. These results can be explained by a
structure in which the monodisperse nanoparticles studied here have a core that
behaves similar to the bulk with a surface layer which does not contribute
significantly to the magnetic order.Comment: 7 pages, 5 figure
Interdisciplinary medication decision making by pharmacists in pediatric hospital settings: An ethnographic study
OBJECTIVE: Children are particularly vulnerable to experiencing medication incidents in hospitals. Making sound medication decisions is therefore of paramount importance. Prior research has principally described pharmacists' role in reducing medication errors. There is a dearth of information about pharmacists' interactions with pediatric hospital staff across disciplines in resolving medication issues. The aim of this study was to examine interdisciplinary medication decision making by pharmacists in pediatric hospital settings. DESIGN: An ethnographic design was undertaken comprising observations, semi-structured interviews and focus groups. Audio-recorded data were analyzed thematically. SETTING: The study was conducted in three wards of an Australian pediatric tertiary teaching hospital, comprising general surgical, gastroenterology, endocrinology, neurology, adolescent and rehabilitation settings. PARTICIPANTS: Pharmacists, registered nurses and doctors were recruited from diverse clinical wards following information sessions. RESULTS: Pharmacists were central to complex pediatric medication decision making, intervening about dosage, administration, drug interactions and authorities. Pharmacists proactively contacted doctors and nurses about prescribing issues; conversely, staff routinely approached pharmacists for medication advice. Pharmacists were perceived as medication experts, their extensive knowledge valued in resolving complex issues: when off-label medications were prescribed, when protocols were absent or ambiguous, where tension existed between protocol adherence and patient safety, and where patients on multiple medications were at risk of medication error. Pharmacists had strong relationships with doctors and nurses, which had a bearing on pharmacists' input in interventions. Furthermore, pharmacists identified prescribing errors through strategies, such as case note review and medication reconciliation, although the lack of emergency department pharmacists and limited after-hours staffing posed challenges to both strategies. CONCLUSIONS: Pharmacists made a substantial and highly valued contribution to pediatric inter-professional medication decision making. These results provide new knowledge that informs theoretical developments of pharmacists' role in decision making
Size matters: the value of small populations for wintering waterbirds
Protecting systematically selected areas of land is a major step towards biodiversity conservation worldwide. Indeed, the identification and designation of protected areas more often than not forms a core component of both national and international conservation policies. In this paper we provide an overview of those Special Protection Areas and Ramsar Sites that have been classified in Great Britain as of 1998/99 for a selection of wintering waterbird species, using bird count data from the Wetland Bird Survey.
The performance of this network of sites is remarkable, particularly in comparison with published analyses of networks elsewhere in the world. Nevertheless, the current site-based approach, whilst having the great benefit of simplicity, is deliberately biased towards aggregating species at the expense of the more dispersed distribution species. To ensure that the network continues successfully to protect nationally and internationally important waterbird populations, efforts now need to concentrate on the derivation of species-specific representation targets and, in particular, the ways in which these can be incorporated into the site selection process. Although these analyses concern the performance of protected areas for waterbirds in Great Britain, the results have wide-ranging importance for conservation planning in general and the design of protected area networks
Magnetic properties of the geometrically frustrated S=1/2 antiferromagnets, La2LiMoO6 and Ba2YMoO6, with the B-site ordered double perovskite structure: Evidence for a Collective Spin Singlet Ground State
Two B-site ordered double perovskites, La2LiMoO6 and Ba2YMoO6, based on the S
= 1/2 ion, Mo5+, have been investigated in the context of geometric magnetic
frustration. Powder neutron diffraction, heat capacity, susceptibility, muon
spin relaxation(_SR), and 89Y NMR- including MAS NMR- data have been collected.
La2LiMoO6 deviates strongly from simple Curie-Weiss paramagnetic behavior below
150K and zero-field cooled/ field cooled (ZFC/FC)irreversibility occurs below
20K with a weak, broad susceptibility maximum near 5K in the ZFC data. A
Curie-Weiss fit shows a reduced mu_eff=1.42\mu_B, (spin only = 1.73 muB) and a
Weiss temperature, \theta_c, which depends strongly on the temperature range of
the fit. Powder neutron diffraction, heat capacity and 7Li NMR show no evidence
for long range magnetic order to 2K. On the other hand oscillations develop
below 20K in muSR indicating at least short range magnetic correlations.
Susceptibility data for Ba2YMoO6 also deviate strongly from the C-W law below
150K with a similarly reduced mu_eff = 1.72\mu_B and \theta_c = - 219(1)K. Heat
capacity, neutron powder diffraction and muSR data show no evidence for long
range order to 2K but a very broad maximum appears in the heat capacity. The
89Y NMR paramagnetic Knight shift shows a remarkable local spin susceptibility
behavior below about 70K with two components from roughly equal sample volumes,
one indicating a singlet state and the other a strongly fluctuating
paramagnetic state. Further evidence for a singlet state comes from the
behavior of the relaxation rate, 1/T1. These results are discussed and compared
with those from other isostructural S = 1/2 materials and those based on S =
3/2 and S = 1.Comment: Accepted for publication in Phys. Rev.
Third structure determination by powder diffractometry round robin (SDPDRR-3)
The results from a third structure determination by powder diffractometry (SDPD) round robin are discussed. From the 175 potential participants having downloaded the powder data, nine sent a total of 12 solutions (8 and 4 for samples 1 and 2, respectively, a tetrahydrated calcium tartrate and a lanthanum tungstate). Participants used seven different computer programs for structure solution (ESPOIR, EXPO, FOX, PSSP, SHELXS, SUPERFLIP, and TOPAS), applying Patterson, direct methods, direct space methods, and charge flipping approach. It is concluded that solving a structure from powder data remains a challenge, at least one order of magnitude more difficult than solving a problem with similar complexity from single-crystal data. Nevertheless, a few more steps in the direction of increasing the SDPD rate of success were accomplished since the two previous round robins: this time, not only the computer program developers were successful but also some users. No result was obtained from crystal structure prediction expert
How many bird and mammal extinctions has recent conservation action prevented?
Aichi Target 12 of the Convention on Biological Diversity (CBD) contains the aim to ‘prevent extinctions of known threatened species’. To measure the degree to which this was achieved, we used expert elicitation to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993–2020 (the lifetime of the CBD) and 2010–2020 (the timing of Aichi Target 12). We found that conservation action prevented 21–32 bird and 7–16 mammal extinctions since 1993, and 9–18 bird and two to seven mammal extinctions since 2010. Many remain highly threatened and may still become extinct. Considering that 10 bird and five mammal species did go extinct (or are strongly suspected to) since 1993, extinction rates would have been 2.9–4.2 times greater without conservation action. While policy commitments have fostered significant conservation achievements, future biodiversity action needs to be scaled up to avert additional extinctions
The impact of social networks on knowledge transfer in long-term care facilities: Protocol for a study
<p>Abstract</p> <p>Background</p> <p>Social networks are theorized as significant influences in the innovation adoption and behavior change processes. Our understanding of how social networks operate within healthcare settings is limited. As a result, our ability to design optimal interventions that employ social networks as a method of fostering planned behavior change is also limited. Through this proposed project, we expect to contribute new knowledge about factors influencing uptake of knowledge translation interventions.</p> <p>Objectives</p> <p>Our specific aims include: To collect social network data among staff in two long-term care (LTC) facilities; to characterize social networks in these units; and to describe how social networks influence uptake and use of feedback reports.</p> <p>Methods and design</p> <p>In this prospective study, we will collect data on social networks in nursing units in two LTC facilities, and use social network analysis techniques to characterize and describe the networks. These data will be combined with data from a funded project to explore the impact of social networks on uptake and use of feedback reports. In this parent study, feedback reports using standardized resident assessment data are distributed on a monthly basis. Surveys are administered to assess report uptake. In the proposed project, we will collect data on social networks, analyzing the data using graphical and quantitative techniques. We will combine the social network data with survey data to assess the influence of social networks on uptake of feedback reports.</p> <p>Discussion</p> <p>This study will contribute to understanding mechanisms for knowledge sharing among staff on units to permit more efficient and effective intervention design. A growing number of studies in the social network literature suggest that social networks can be studied not only as influences on knowledge translation, but also as possible mechanisms for fostering knowledge translation. This study will contribute to building theory to design such interventions.</p
