Injury classification influences type and quantity of PT interventions during inpatient SCI rehabilitation and is a strong predictor of outcomes at discharge and 1 year post-injury. The impact of PT treatment increases when patient groupings become more homogeneous and outcomes become specific to the groupings. Note: This is the second of nine articles in the SCIRehab series.
Abstract. The Southern Ocean region is one of the most pristine in the world and serves as an important proxy for the pre-industrial atmosphere. Improving our understanding of the natural processes in this region is likely to result in the largest reductions in the uncertainty of climate and earth system models. While remoteness from anthropogenic and continental sources is responsible for its clean atmosphere, this also results in the dearth of atmospheric observations in the region. Here we present a statistical summary of the latitudinal gradient of aerosol (condensation nuclei larger than 10 nm, CN10) and cloud condensation nuclei (CCN at various supersaturations) concentrations obtained from five voyages spanning the Southern Ocean between Australia and Antarctica from late spring to early autumn (October to March) of the 2017/18 austral seasons. Three main regions of influence were identified: the northern sector (40–45∘ S), where continental and anthropogenic sources coexisted with background marine aerosol populations; the mid-latitude sector (45–65∘ S), where the aerosol populations reflected a mixture of biogenic and sea-salt aerosol; and the southern sector (65–70∘ S), south of the atmospheric polar front, where sea-salt aerosol concentrations were greatly reduced and aerosol populations were primarily biologically derived sulfur species with a significant history in the Antarctic free troposphere. The northern sector showed the highest number concentrations with median (25th to 75th percentiles) CN10 and CCN0.5 concentrations of 681 (388–839) cm−3 and 322 (105–443) cm−3, respectively. Concentrations in the mid-latitudes were typically around 350 cm−3 and 160 cm−3 for CN10 and CCN0.5, respectively. In the southern sector, concentrations rose markedly, reaching 447 (298–446) cm−3 and 232 (186–271) cm−3 for CN10 and CCN0.5, respectively. The aerosol composition in this sector was marked by a distinct drop in sea salt and increase in both sulfate fraction and absolute concentrations, resulting in a substantially higher CCN0.5/CN10 activation ratio of 0.8 compared to around 0.4 for mid-latitudes. Long-term measurements at land-based research stations surrounding the Southern Ocean were found to be good representations at their respective latitudes; however this study highlighted the need for more long-term measurements in the region. CCN observations at Cape Grim (40∘39′ S) corresponded with CCN measurements from northern and mid-latitude sectors, while CN10 observations only corresponded with observations from the northern sector. Measurements from a simultaneous 2-year campaign at Macquarie Island (54∘30′ S) were found to represent all aerosol species well. The southernmost latitudes differed significantly from both of these stations, and previous work suggests that Antarctic stations on the East Antarctic coastline do not represent the East Antarctic sea-ice latitudes well. Further measurements are needed to capture the long-term, seasonal and longitudinal variability in aerosol processes across the Southern Ocean.
ObjectiveIn recent years, there have been considerable increases in both the utilisation and reported harms of prescription opioids in Australia. This report details the development of adaptable resources, implementation and the evaluation of pilot projects that optimise oxycodone prescribing and introduce concepts of opioid stewardship into hospital settings. MethodsAn adaptable suite of resources, based on principles of implementation science, was developed and used to facilitate the projects. Local prescribing practice audits of oxycodone guided the development of context-sensitive educational strategies that were piloted and evaluated in a repeat audit. The primary outcome was the proportion of oxycodone prescriptions indicating tailored prescribing practices. In emergency departments (EDs), a prescription was considered tailored if it was for ≤10 tablets. In surgery, tailored prescriptions were those given to patients who had required opioids in the 24h before discharge. ResultsCumulative results of the pilot projects in three EDs demonstrated improved rates of tailored oxycodone prescribing on discharge (62% vs 90%; P<0.0001). In the surgical setting of one hospital, tailored prescribing increased significantly (from 76% to 91%; P=0.013) and was accompanied by a halving of the proportion of patients receiving oxycodone prescriptions (36% vs 18%; P<0.001). ConclusionsThe implementation of facilitated, adaptable, prescriber-led quality improvement projects significantly improved tailored oxycodone prescribing practices and provides a platform to advance further opioid-related practice improvement in Australia. What is known about the topic?The increasing trend in opioid prescribing, misuse, harm and death in Australia, and the potential for hospital prescribing to contribute to long-term opioid use, is well known. Recent changes to the Pharmaceutical Benefits Scheme are designed to help better identify patients who need oxycodone on discharge and the quantity to prescribe, rather than default prescribing. However, how to implement tailored prescribing has not been described in detail in the Australian literature. What does this paper add?This paper adds to the mass of literature describing the ‘problem’ of opioid prescribing by providing a ‘solution’ in the form of evidence for the implementation of a facilitated and adaptable quality improvement strategy in emergency and surgical settings. The focus is not on a reduction of opioids, but rather on providing tailored pain management and opioid prescribing. What are the implications for practitioners?This paper provides a practical, pragmatic and achievable starting point for other Australian practitioners to adapt the described processes and take the first steps towards opioid stewardship in their setting.
Background/Objective: Outcomes research is in need of a classification system of physical therapy (PT) interventions for acute traumatic spinal cord injury (SCI) rehabilitation in the United States. The objective of this study was to describe a taxonomy (system to categorize and classify interventions) to examine the effects of PT interventions on rehabilitation outcomes. Methods: The SCIRehab study uses the rigorous observational practice-based evidence methodology to examine current treatment processes without changing existing practice. PT clinicians and researchers from 6 centers developed a taxonomy to describe details of each PT session. Results: The PT taxonomy consists of 19 treatment activities (eg, bed mobility, transfers, wheelchair mobility, strengthening and stretching exercises) and supplementary information to describe the associated therapeutic interventions. Details that focus on patient assistance needs and family involvement are included as additional descriptors to help to describe and justify PT activity selection. Time spent on each activity is used as the measure of intensity. Conclusion: The detailed PT taxonomy documentation process, which offers efficiency in data collection, is being used for all PT sessions with 1,500 patients with acute traumatic SCI at the 6 participating centers. It might be the first attempt to document the many details of the PT rehabilitation process for patients with SCI in the United States.
The current study provides preliminary evidence documenting the limited use of complementary therapies in rehabilitation settings and highlights the opportunity for further research, particularly regarding pain-related outcomes.
