Analysis of Centralized Efficiency Improvement Practices in Australian Public Health Systems
Aim: Analysis of centralized efficiency improvement practices in Australian public health systems. Introduction: Public health systems seek to maximize outcomes generated for resources used through efficiency improvement (EI) in response to funding and demand pressures. Despite this focus, evidence for EI approaches at the whole-of-system level is lacking in the literature. There is an urgent need for evidence-based approaches to centralized EI to address these pressures. This study aims to address this gap by answering the research question “How is EI conceptualized and managed by central public health system management entities in Australia?”. Material and Methods: Document analysis was selected due to its suitability for systematically searching and appraising health system documentation, with this study following Altheide’s approach focusing on whole-of-system strategic plan and management framework documents originating from Australian public health organizations. Results: Conceptualization of efficiency varied substantially with no consistent definition identified, however common attributes included resource use, management, service and delivery. Forty-two of 43 documents contained approaches associated with improving efficiency at the whole of system level. Discussion: While no comprehensive framework for centralized EI was evident, we identified nine core approaches which together characterize centralized EI. Together these approaches represent a comprehensive evidence-based approach to EI at the whole of system level. Conclusion: The approaches to whole-of-system EI identified in this study are likely to be highly transferable across health systems internationally with approaches including strategic priority setting, incentivization, performance support, use of EI evidence, digital enablement and workforce capability development
Systematic review of conservation interventions to promote voluntary behavior change
Understanding human behavior is vital to developing interventions that effectively lead to proenvironmental behavior change, whether the focus is at the individual or societal level. However, interventions in many fields have historically lacked robust forms of evaluation, which makes it hard to be confident that these conservation interventions have successfully helped protect the environment. We conducted a systematic review to assess how effective nonpecuniary and nonregulatory interventions have been in changing environmental behavior. We applied the Office of Health Assessment and Translation systematic review methodology. We started with more than 300,000 papers and reports returned by our search terms and after critical appraisal of quality identified 128 individual studies that merited inclusion in the review. We classified interventions by thematic area, type of intervention, the number of times audiences were exposed to interventions, and the length of time interventions ran. Most studies reported a positive effect (n = 96). The next most common outcome was no effect (n = 28). Few studies reported negative (n = 1) or mixed (n = 3) effects. Education, prompts, and feedback interventions resulted in positive behavior change. Combining multiple interventions was the most effective. Neither exposure duration nor frequency affected the likelihood of desired behavioral change. Comparatively few studies tested the effects of voluntary interventions on non-Western populations (n = 17) or measured actual ecological outcome behavior (n = 1). Similarly, few studies examined conservation devices (e.g., energy-efficient stoves) (n = 9) and demonstrations (e.g., modeling the desired behavior) (n = 5). There is a clear need to both improve the quality of the impact evaluation conducted and the reporting standards for intervention results
Salinity and temperature affect the symbiont profile and host condition of Florida USA blue crabs Callinectes sapidus
Subtropical Florida blue crabs, Callinectes sapidus, exhibit differing life history traits compared to their temperate counterparts, likely influencing symbiont infection dynamics. Little information exists for Florida C. sapidus symbiont profiles, their distribution among various habitats, and influence on crab condition. Using histopathology, genomics, and transmission electron microscopy, we describe the first symbiont profiles for Florida C. sapidus occupying freshwater to marine habitats. Twelve symbiont groups were identified from 409 crabs including ciliophorans, digenean, microsporidian, Haplosporidia, Hematodinium sp., Nematoda, filamentous bacteria, gregarine, Callinectes sapidus nudivirus, Octolasmis sp., Cambarincola sp., and putative microcell. Overall, 78% of C. sapidus were documented with one or more symbiont groups demonstrating high infection rates in wild populations. Environmental variables water temperature and salinity explained 48% of the variation in symbiont groups among Florida habitats, and salinity was positively correlated with C. sapidus symbiont diversity. This suggests freshwater C. sapidus possess fewer symbionts and represent healthier individuals compared to saltwater populations. Crab condition was examined using the reflex action mortality predictor (RAMP) to determine if reflex impairment could be linked to symbiont prevalence. Symbionts were found positively correlated with crab condition, and impaired crabs were more likely to host symbionts, demonstrating symbiont inclusion may boost predictive ability of the RAMP application. The microsporidian symbiont group had a particularly strong effect on C. sapidus reflex response, and impairment was on average 1.57 times higher compared to all other symbiont groups. Our findings demonstrate the importance of considering full symbiont profiles and their associations with a spatially and temporally variable environment to fully assess C. sapidus population health.</p
Factors prospectively associated with physical activity and dietary related outcomes in people with severe mental illness: A systematic review of longitudinal studies.
Understanding factors that contribute towards physical activity and diet outcomes are important for health improvement in people with severe mental illness. Cross-sectional findings on factors associated with diet and physical activity outcomes provide limited information on what predicts changes or long-term outcomes in lifestyle behaviours in people with severe mental illness. A systematic review was therefore conducted to identify prospective studies with quantitative data on baseline factors associated with follow-up diet or physical activity related outcomes. MEDLINE, EMBASE, PsycINFO, CINAHL Plus and grey literature databases were searched from inception to March 2018. From 6921 studies, 5 were eligible for physical activity related outcomes and 2 for diet related outcomes. The follow-up duration was 4 weeks to 24 months and participants were mostly diagnosed with schizophrenia. Older age was commonly related to better physical activity related outcomes, whilst higher negative symptoms were related to poorer-related outcomes. Physical activity intentions and gender were unrelated to physical activity outcomes. There was a lack of data on factors influencing dietary outcomes. Although there were some common factors predictive of physical activity including older age and negative symptoms, more high-quality research is needed to determine the effect of sociodemographic, mental health, social, clinical, lifestyle and other factors on both physical activity and dietary outcomes
A primary care-led intervention to reduce cardiovascular disease risk in people with severe mental illness (PRIMROSE): a secondary qualitative analysis
Background: Despite various initiatives, the mortality rate in people with severe mental illness increased between 2004 and 2014. Poor health behaviours contribute, including poor diets, physical inactivity, smoking, and excessive alcohol consumption. Evidence is scarce regarding how primary care interventions can influence health behaviour change in people with severe mental illness. We aimed to explore how health behaviours were supported and changed in people with severe mental illness via an intervention (PRIMROSE) informed by the behaviour change wheel. Methods: PRIMROSE was delivered over 6 months in primary care across England. We did a secondary qualitative analysis of semi-structured interviews with staff and patients describing their experiences of PRIMROSE. The sample were selected from a random 20% of primary care practices in England. Topic guides were based on the capability, opportunity, motivation, and behaviour (COM-B) model of behaviour and the Theoretical Domains Framework. We identified how behaviour change techniques were applied by mapping the coded data to the behaviour change technique taxonomy (version 1). We explored barriers, facilitators, and processes of supporting or making health behaviour changes using thematic analysis. Themes were further informed by COM-B. Findings: Between April 27 and Dec 19, 2016, 15 patients and 15 health-care professionals participated from a broad range of backgrounds across England, but with limited ethnic diversity. We identified 20 behaviour change techniques being used. Six factors affected supporting and changing health behaviours: motivation, motivated patients were more proactive to action advice, which was affected by witnessing physical health benefits; health knowledge or perceptions, developing knowledge on how to change health behaviour facilitated motivation but negative health perceptions could be difficult to change; difficulties with patient capability, mental and physical health status affected motivation; staff proficiency, previous experience with mental health and motivational interviewing skills aided supporting patients; social influences, patients felt pressure to achieve goals to avoid staff disappointment—creating healthy social (peer) norms facilitated motivation whereas unhealthy norms prevented changes; and environmental level influences, access to time and resources were perceived as critical. Making use of existing opportunities for behaviour change, such as open spaces for walking, facilitated positive changes. Interpretation: The value of the application of behaviour change techniques and primary health-care professionals in supporting health behaviour change in this population was variable. For some, such techniques helped to increase motivation, capability, and opportunity to change health behaviours. In others, complex challenges that people with severe mental illness experienced prevented behaviour change. Our findings suggest that with training and appropriate resources, primary care health-care professionals can facilitate health behaviour change in some cases, but policy makers and commissioners should consider enabling more interdisciplinary involvement
Exploring how health behaviours are supported and changed in people with severe mental illness: A qualitative study of a cardiovascular risk reducing intervention in Primary Care in England.
Objectives This study explored how health behaviours were supported and changed in people with severe mental illness by primary health care professionals trained in delivering behaviour change techniques (BCTs) within a cardiovascular disease risk reducing intervention. Design Secondary qualitative analysis of 30 staff and patient interviews. Methods We mapped coded data to the BCT Taxonomy (version 1) to identify BCT application. Thematic analysis was conducted to explore the barriers and facilitators of supporting and changing health behaviours. Themes were then interpreted using the Capability, Opportunity, Motivation, and Behaviour model to gain greater explanation behind the processes. Results Twenty BCTs were identified. Staff and patients perceived that health behaviours were commonly affected by both automatic and reflective motivation, sometimes in turn affected by psychological capability, social, and physical opportunity. Staff and patients suggested that motivation was enhanced by both patient and staff ability to observe health benefits, in some cases patients' health knowledge, mental health status, and social support networks. It was suggested that engaging in/sustaining healthy behaviours was influenced by physical opportunities to engrain behaviours into routine. Conclusions According to staff and patients, health behaviour change in this population was driven by complex processes. It was suggested that capability, opportunity, and motivation were in some cases enhanced by BCTs, but variable. Behaviour change may be optimized by individualized behavioural assessments, identifying drivers of behaviour and applying a range of BCTs may help to target individual needs. Patient peer-led approaches, techniques to encourage awareness of visible success, and normalizing health behaviours may increase behaviour change. Statement of contribution What is already known on this subject? Poorer health behaviours may contribute to early mortality rates in people with severe mental illness. Health care professionals are encouraged to target the uptake of healthy behaviours, but there is limited guidance on how. The processes that cause or inhibit health behaviour change within interventions that use behaviour change techniques by health care practitioners are unclear. What does the study add? Staff and patients suggested that behaviour change techniques (BCTs) in some cases increased capability, opportunity, and motivation to engage in healthy behaviours, but in other cases had variable success. Staff and patients reported that in some cases, motivation impacted health behaviour change and was in turn affected by psychological capability, social, and physical opportunity. Individualized behavioural assessments, flexible approaches to BCT application, involvement from patient peer support and different ways of targeting patient motivation may help to increase healthy behaviour changes in this population
A qualitative study exploring the barriers and facilitators of implementing a cardiovascular disease risk reducing intervention for people with severe mental illness into primary care contexts across England: the 'PRIMROSE' trial.
BACKGROUND: People with severe mental illness (SMI) are at greater risk of earlier mortality due to physical health problems including cardiovascular disease (CVD). There is limited work exploring whether physical health interventions for people with SMI can be embedded and/or adopted within specific healthcare settings. This information is necessary to optimise the development of services and interventions within healthcare settings. This study explores the barriers and facilitators of implementing a nurse-delivered intervention ('PRIMROSE') designed to reduce CVD risk in people with SMI in primary care, using Normalisation Process Theory (NPT), a theory that explains the dynamics of embedding or 'normalising' a complex intervention within healthcare settings. METHODS: Semi-structured interviews were conducted between April-December 2016 with patients with SMI at risk of CVD who received the PRIMROSE intervention, and practice nurses and healthcare assistants who delivered it in primary care in England. Interviews were audio recorded, transcribed and analysed using thematic analysis. Emergent themes were then mapped on to constructs of NPT. RESULTS: Fifteen patients and 15 staff participated. The implementation of PRIMROSE was affected by the following as categorised by the NPT domains: 1) Coherence, where both staff and patients expressed an understanding of the purpose and value of the intervention, 2) Cognitive participation, including mental health stigma and staff perceptions of the compatibility of the intervention to primary care contexts, 3) Collective action, including 3.1. Interactional workability in terms of lack of patient engagement despite flexible appointment scheduling. The structured nature of the intervention and the need for additional nurse time were considered barriers, 3.2. Relational integration i.e. whereby positive relationships between staff and patients facilitated implementation, and access to 'in-house' staff support was considered important, 3.3. Skill-set workability in terms of staff skills, knowledge and training facilitated implementation, 3.4. Contextual integration regarding the accessibility of resources sometimes prevented collective action. 4) Reflexive monitoring, where the staff commonly appraised the intervention by suggesting designated timeslots and technology may improve the intervention. CONCLUSIONS: Future interventions for physical health in people with SMI could consider the following items to improve implementation: 1) training for practitioners in CVD risk prevention to increase practitioners knowledge of physical interventions 2) training in SMI to increase practitioner confidence to engage with people with SMI and reduce mental health stigma and 3) access to resources including specialist services, additional staff and time. Access to specialist behaviour change services may be beneficial for patients with specific health goals. Additional staff to support workload and share knowledge may also be valuable. More time for appointments with people with SMI may allow practitioners to better meet patient needs
PTF10fqs: A Luminous Red Nova in the Spiral Galaxy Messier 99
The Palomar Transient Factory (PTF) is systematically charting the optical
transient and variable sky. A primary science driver of PTF is building a
complete inventory of transients in the local Universe (distance less than 200
Mpc). Here, we report the discovery of PTF10fqs, a transient in the luminosity
"gap" between novae and supernovae. Located on a spiral arm of Messier 99, PTF
10fqs has a peak luminosity of Mr = -12.3, red color (g-r = 1.0) and is slowly
evolving (decayed by 1 mag in 68 days). It has a spectrum dominated by
intermediate-width H (930 km/s) and narrow calcium emission lines. The
explosion signature (the light curve and spectra) is overall similar to thatof
M85OT2006-1, SN2008S, and NGC300OT. The origin of these events is shrouded in
mystery and controversy (and in some cases, in dust). PTF10fqs shows some
evidence of a broad feature (around 8600A) that may suggest very large
velocities (10,000 km/s) in this explosion. Ongoing surveys can be expected to
find a few such events per year. Sensitive spectroscopy, infrared monitoring
and statistics (e.g. disk versus bulge) will eventually make it possible for
astronomers to unravel the nature of these mysterious explosions.Comment: 12 pages, 12 figures, Replaced with published versio
The underutilisation of dual antiplatelet therapy in acute coronary syndrome
Background Despite guideline recommendation of dual antiplatelet therapy (DAPT) in treating ACS, DAPT is underutilized. Our objective was to determine independent predictors of DAPT non-prescription in ACS and describe pattern of DAPT prescription over time. Methods Patients presenting to 41 Australian hospitals with an ACS diagnosis between 2009 and 2016 were stratified according to discharge prescription with DAPT and single antiplatelet therapy (SAPT) or no antiplatelet therapy. Multiple stepwise logistic regression, accounting for within hospital clustering, was used to determine the independent predictors of DAPT non-prescription, defined as discharge with SAPT alone or no antiplatelet agent. Results 8939 patients survived to discharge with an ACS diagnosis. Of these, 6294 (70.4%) patients were discharged on DAPT, 2154 (24.1%) on SAPT and 491 (5.5%) on no antiplatelet agent. Independent predictors of DAPT non-prescription in the overall cohort were: in-hospital CABG (OR 0.09, 95%CI 0.05–0.14), discharge with warfarin (0.10 (0.07–0.14)), in hospital major bleeding (0.48 (0.34–0.67), diagnosis of unstable angina (0.35, (0.27–0.45)), non-ST-elevation myocardial infarction (0.67 (0.57–0.78)) [both vs. ST-segment elevation myocardial infarction], in hospital atrial arrhythmia (0.72 (0.60–0.86)), history of hypertension (0.83 (0.73–0.94)) and GRACE high risk (0.83 (0.71–0.98)). There was an increase in prescription of DAPT and a shift towards ticagrelor over clopidogrel for ACS from 2013 to 2016 (p\ua
