Reconceptualizing Patient Safety Beyond Harm: Insights From a Mixed-Methods Qualitative Inquiry.

BACKGROUND: Although patients' and care partners' perspectives on patient safety can guide health care learning and improvements, this information remains underutilized. Efforts to leverage this valuable data require challenging the narrow focus of safety as the absence of harm. PURPOSE: The purpose of this study was to gain a broader insight into how patients and care partners perceive and experience safety. METHODS: We used a mixed-methods approach that included a literature review and interviews and focus groups with patients, care partners, and health care providers. An emergent coding schema was developed from triangulation of the 2 data sets. RESULTS: Two core themes-feeling unsafe and feeling safe-emerged that collectively represent a broader view of safety. CONCLUSION: Knowledge from patients and care partners about feeling unsafe and safe needs to inform efforts to mitigate harm and promote safety, well-being, and positive outcomes and experiences.

Refocusing on Patient Safety.

Patient safety provides an important foundation for high-quality care. Research in Canada and elsewhere has identified substantial levels of harm in hospitals and other settings; these results spurred the development and spread of safety practices, along with strategies to strengthen organizational training, incident reporting and analysis and a host of resources intended to reduce the burden of harm. Yet, despite these efforts, 20 years after the publication of the Canadian Adverse Event study (Baker et al. 2004) and other studies, many leaders believe progress in patient safety has stalled (NEJM Catalyst 2023). Indeed, some recent studies indicate that the levels of harm have increased. One notable study by David Bates and colleagues (2023), building on approaches used in earlier studies, identified at least one adverse event in 23.6% of a random sample of patients in Massachusetts hospitals in 2018. Among 978 events, 22.7% were judged preventable and one-third required at least substantial intervention or prolonged recovery.

Building High-Performing Primary Care Systems: After a Decade of Policy Change, Is Canada "Walking the Talk?"

Policy Points Considerable investments have been made to build high-performing primary care systems in Canada. However, little is known about the extent to which change has occurred over the last decade with implementing programs and policies across all 13 provincial and territorial jurisdictions. There is significant variation in the degree of implementation of structural features of high-performing primary care systems across Canada. This study provides evidence on the state of primary care reform in Canada and offers insights into the opportunities based on changes that governments elsewhere have made to advance primary care transformation. CONTEXT: Despite significant investments to transform primary care, Canada lags behind its peers in providing timely access to regular doctors or places of care, timely access to care, developing interprofessional teams, and communication across health care settings. This study examines changes over the last decade (2012 to 2021) in policies across 13 provincial and territorial jurisdictions that address the structural features of high-performing primary care systems. METHODS: A multiple comparative case study approach was used to explore changes in primary care delivery across 13 Canadian jurisdictions. Each case consisted of (1) qualitative interviews with academics, provincial health care leaders, and health care professionals and (2) a literature review of policies and innovations. Data for each case were thematically analyzed within and across cases, using 12 structural features of high-performing primary care systems to describe each case and assess changes over time. FINDINGS: The most significant changes include adopting electronic medical records, investments in quality improvement training and support, and developing interprofessional teams. Progress was more limited in implementing primary care governance mechanisms, system coordination, patient enrollment, and payment models. The rate of change was slowest for patient engagement, leadership development, performance measurement, research capacity, and systematic evaluation of innovation. CONCLUSIONS: Progress toward building high-performing primary care systems in Canada has been slow and variable, with limited change in the organization and delivery of primary care. Canada's experience can inform innovation internationally by demonstrating how preexisting policy legacies constrain the possibilities for widespread primary care reform, with progress less pronounced in the attributes that impact physician autonomy. To accelerate primary care transformation in Canada and abroad, a national strategy and performance measurement framework is needed based on meaningful engagement of patients and other stakeholders. This must be accompanied by targeted funding investments and building strong data infrastructure for performance measurement to support rigorous research.

Automated Identification of Patent Ductus Arteriosus Using a Computer Vision Model.

OBJECTIVES: Patent ductus arteriosus (PDA) is a vascular defect common in preterm infants and often requires treatment to avoid associated long-term morbidities. Echocardiography is the primary tool used to diagnose and monitor PDA. We trained a deep learning model to identify PDA presence in relevant echocardiographic images. METHODS: Echocardiography video clips (n = 2527) in preterm infants were reviewed by a pediatric cardiologist and those relevant to PDA diagnosis were selected and labeled (PDA present/absent/indeterminate). We trained a convolutional neural network to classify each echocardiography frame of a clip as belonging to clips with or without PDA. A novel attention mechanism that aggregated predictions for all frames in each clip to obtain a clip-level prediction by weighting relevant frames. RESULTS: In early model iterations, we discovered training with color Doppler echocardiography clips produced the best performing classifier. For model training and validation, 1145 such clips from 66 patients (661 PDA+ clips, 484 PDA- clips) were used. Our best classifier for clip level performance obtained sensitivity of 0.80 (0.83-0.90), specificity of 0.77 (0.62-0.92) and AUC of 0.86 (0.83-0.90). Study level performance obtained sensitivity of 0.83 (0.72-0.94), specificity of 0.89 (0.79-1.0) and AUC of 0.93 (0.89-0.98). CONCLUSIONS: Our novel deep learning model demonstrated strong performance in classifying echocardiography clips with and without PDA. Further model development and external validation are warranted. Ultimately, integration of such a classifier into auto detection software could streamline PDA imaging workflow. This work is the first step toward semi-automated, bedside detection of PDA in preterm infants.

Identification and Adjudication of Adverse Events Following Rectal Cancer Surgery: Observational Case Series in a Region of Ontario, Canada.

BACKGROUND: For patients undergoing rectal cancer surgery, we evaluated whether suboptimal preoperative surgeon evaluation of resection margins is a latent condition factor-a factor that is common, unrecognized, and may increase the risk of certain adverse events, including local tumour recurrence, positive surgical margin, nontherapeutic surgery, and in-hospital mortality. METHODS: In this observational case series of patients who underwent rectal cancer surgery during 2016 in Local Health Integrated Network 4 region of Ontario (population 1.4 million), chart review and a trigger tool were used to identify patients who experienced the adverse events. An expert panel adjudicated whether each event was preventable or nonpreventable and identified potential contributing factors to adverse events. RESULTS: Among 173 patients, 25 (14.5%) had an adverse event and 13 cases (7.5%) were adjudicated as preventable. Rate of surgeon awareness of preoperative margin status was low at 50% and similar among cases with and without an adverse event (p = 0.29). Suboptimal surgeon preoperative evaluation of surgical margins was adjudicated a contributing factor in all 11 preventable local recurrence, positive margin, and nontherapeutic surgery cases. Failure to rescue was judged a contributing factor in the two cases with preventable in-hospital mortality. CONCLUSIONS: Suboptimal surgeon preoperative evaluation of surgical margins in rectal cancer is likely a latent condition factor. Optimizing margin evaluation may be an efficient quality improvement target.

Impacts of patient and family engagement in hospital planning and improvement: qualitative interviews with patient/family advisors and hospital staff.

BACKGROUND: Patient engagement (PE) in hospital planning and improvement is widespread, yet we lack evidence of its impact. We aimed to identify benefits and harms that could be used to assess the impact of hospital PE. METHODS: We interviewed hospital-affiliated persons involved in PE activities using a qualitative descriptive approach and inductive content analysis to derive themes. We interpreted themes by mapping to an existing framework of healthcare performance measures and reported themes with exemplar quotes. RESULTS: Participants included 38 patient/family advisors, PE managers and clinicians from 9 hospitals (2 < 100 beds, 4 100 + beds, 3 teaching). Benefits of PE activities included 9 impacts on the capacity of hospitals. PE activities involved patient/family advisors and clinicians/staff in developing and spreading new PE processes across hospital units or departments, and those involved became more adept and engaged. PE had beneficial effects on hospital structures/resources, clinician staff functions and processes, patient experience and patient outcomes. A total of 14 beneficial impacts of PE were identified across these domains. Few unintended or harmful impacts were identified: overextended patient/family advisors, patient/family advisor turnover and clinician frustration if PE slowed the pace of planning and improvement. CONCLUSIONS: The 23 self reported impacts were captured in a Framework of Impacts of Patient/Family Engagement on Hospital Planning and Improvement, which can be used by decision-makers to assess and allocate resources to hospital PE, and as the basis for ongoing research on the impacts of hospital PE and how to measure it.

Using Case Costing to Evaluate the Potential Impact of a Reintegration Unit on an Acute-Care Hospital's Capacity and Resources.

The Ontario Ministry of Health funded a reintegration unit to transition hospitalized patients who no longer required acute care to alternate level of care (ALC), such as long-term care. In its first year, 102 (3.5%) patients of the hospital's waiting-for-ALC population were transferred, with 37.3% transferred on the day of ALC readiness. The reintegration unit reduced direct hospital costs by $861,000. Using case costing, we modelled optimized scenarios including all transfers on the day of ALC readiness and increased transfers to the reintegration unit; this helped reduce avoided direct costs by $2.3-$5.4 million. Acute-care bed capacity could have increased by 11%. We outline strategies to optimize future performance of the reintegration unit.

Prenatal exposure to consumer product chemical mixtures and size for gestational age at delivery.

BACKGROUND: While fetal growth is a tightly regulated process, it is sensitive to environmental exposures that occur during pregnancy. Many commonly used consumer products contain chemicals that can disturb processes underlying fetal growth. However, mixtures of these chemicals have been minimally examined. We investigated associations between prenatal exposure to 33 consumer product chemicals (nine organophosphate ester flame retardant [OPE] metabolites, 12 phthalate metabolites, and 12 phenols) and the odds of small- or large-for-gestational age (SGA and LGA) births. METHODS: This case-control study was comprised of SGA (N = 31), LGA (N = 28), and appropriate for gestational age control (N = 31) births selected from the larger LIFECODES cohort. Biomarkers of exposure to consumer product chemicals were quantified in maternal urine collected from up to three study visits during pregnancy. In a single-pollutant approach, odds ratios (OR) and 95% confidence intervals (CI) of SGA and LGA associated with an interquartile range (IQR)-increase in exposure biomarkers were estimated using multinomial logistic regression. In a multi-pollutant approach, quantile g-computation was used to jointly estimate the OR (95% CI) of SGA and LGA per simultaneous one quartile-change in all biomarkers belonging to each chemical class. RESULTS: Among the 33 biomarkers analyzed, 20 were detected in at least 50% of the participants. After adjusting for potential confounders, we observed reduced odds of LGA in association with higher urinary concentrations of several exposure biomarkers. For example, an IQR-increase in the OPE metabolite, diphenyl phosphate, was associated with lower odds of LGA (OR: 0.40 [95% CI: 0.18, 0.87]). Using quantile g-computation, we estimated lower odds of an LGA birth for higher OPE metabolite concentrations (OR: 0.49 [95% CI: 0.27, 0.89]) and phthalate metabolite concentrations (OR: 0.23 [95% CI: 0.07, 0.73]). Associations between consumer product chemicals and SGA were largely null. CONCLUSIONS: Joint exposure to OPEs and phthalates was associated with lower odds of delivering LGA. Associations with LGA could indicate a specific impact of these exposures on the high end of the birth weight spectrum. Future work to understand this nuance in the associations between consumer product chemical mixtures and fetal growth is warranted.

Disability progression in multiple sclerosis is associated with plasma neuroactive steroid profile.

BACKGROUND: Neuroactive steroids (NASs) exert multiple biological effects on development and inflammation. The effects of NASs on disease progression in multiple sclerosis (MS) are uncertain, prompting analyses of NAS profiles during the transition from clinically isolated syndrome (CIS) to relapsing-remitting (RR) MS. METHODS: Subjects with CIS or RRMS and healthy controls (HCs) were recruited; demographic and clinical data as well as disability scores measured by the Expanded Disability Status Scale (EDSS) were recorded. Matched plasma NAS and amino acid (AA) concentrations were measured. RESULTS: HC (n = 17), CIS (n = 31), and RRMS (n = 33) groups showed similar ages and sex distribution although disability scores were higher in the RRMS group. The conversion rate of CIS to RRMS group was 51.6% (n = 16) during a mean follow-up period of 1.85 years. The RRMS group showed significantly higher mean allopregnanolone, aspartate, and taurine concentrations with lower epiallopregnanolone concentrations than CIS patients, and higher L-serine-O-phosphate and lower alanine, arginine, and glutamine concentrations than the HC group. Among CIS and RRMS groups, multivariate hierarchical regressions revealed that higher concentrations of plasma tetrahydrodeoxycorticosterone (THDOC) may predict disability worsening. CONCLUSIONS: RRMS and CIS patients exhibited differing concentrations of both NASs and AAs in plasma while both THDOC and pregnanolone might serve as biomarkers of disability worsening.

Interprofessional and multiprofessional approaches in quality improvement education.

The imperative for all healthcare professionals to partake in quality improvement (QI) has resulted in the development of QI education programs with participants from different professional backgrounds. However, there is limited empirical and theoretical examination as to why, when and how interprofessional and multiprofessional education occurs in QI and the outcomes of these approaches. This paper reports on a qualitative collective case study of interprofessional and multiprofessional education in three longitudinal QI education programs. We conducted 58 interviews with learners, QI project coaches, program directors and institutional leads and 135 h of observations of in-class education sessions, and collected relevant documents such as course syllabi and handouts. We used an interpretive thematic analysis using a conventional and directed content analysis approach. In the directed content approach, we used sociology of professions theory with particular attention to professional socialization, hierarchies and boundaries in QI, to understand the ways in which individuals' professional backgrounds informed the planning and experiences of the QI education programs. Findings demonstrated that both interprofessional and multiprofessional education approaches were being used to achieve different education objectives. While each approach demonstrated positive learning and practice outcomes, tensions related to the different ways in which professional groups are engaging in QI, power dynamics between professional groups, and disconnects between curricula and practice existed. Further conceptual clarity is essential for a more informed discussion about interprofessional and multiprofessional education approaches in QI and explicit attention is needed to professional processes and tensions, to optimize the impact of education on practice.

Applying the principles of adaptive leadership to person-centred care for people with complex care needs: Considerations for care providers, patients, caregivers and organizations.

BACKGROUND: Health systems in many countries see person-centred care as a critical component of high-quality care but many struggle to operationalize it in practice. We argue that models such as adaptive leadership can be a critical lever to support person-centred care, particularly for people who have multiple complex care needs. OBJECTIVE: To reflect on two concepts: person-centred care and adaptive leadership and share how adaptive leadership can advance person-centred care at the front-line care delivery level and the organizational level. FINDINGS: The defining feature of adaptive leadership is the separation of technical solutions (ie applying existing knowledge and techniques to problems) from adaptive solutions (ie requiring shifts in how people work together, not just what they do). Addressing adaptive challenges requires identifying key assumptions that may limit motivations for change and the behaviours influenced by these assumptions. Thus, effective care for patients, particularly those with multiple complex care needs, often entails helping care providers and patients to examine their relationships and behaviours not just identifying technical solutions. Addressing adaptive challenges also requires a supportive and enabling organizational context. We provide illustrative examples of how adaptive leadership principles can be applied at both the front line of care and the organization level in advancing person-centred care delivery. CONCLUSIONS: Advancing person-centred care at both the clinical and organizational levels requires a growth mindset, a willingness to try (and fail) and try again, comfort in being uncomfortable and a commitment to figure things out, in partnership, in iterative ways. Patients, caregivers, care providers and organizational leaders all need to be adaptive leaders in this endeavour.

Approaches to optimize patient and family engagement in hospital planning and improvement: Qualitative interviews.

BACKGROUND: Patient engagement (PE) in health-care planning and improvement is a growing practice. We lack evidence-based guidance for PE, particularly in hospital settings. This study explored how to optimize PE in hospitals. METHODS: This study was based on qualitative interviews with individuals in various roles at hospitals with high PE capacity. We asked how patients were engaged, rationale for approaches chosen and solutions for key challenges. We identified themes using content analysis. RESULTS: Participants included 40 patient/family advisors, PE managers, clinicians and executives from 9 hospitals (2 < 100 beds, 4 100 + beds, 3 teaching). Hospitals most frequently employed collaboration (standing committees, project teams), followed by blended approaches (collaboration + consultation), and then consultation (surveys, interviews). Those using collaboration emphasized integrating perspectives into decisions; those using consultation emphasized capturing diverse perspectives. Strategies to support engagement included engaging diverse patients, prioritizing what benefits many, matching patients to projects, training patients and health-care workers, involving a critical volume of patients, requiring at least one patient for quorum, asking involved patients to review outputs, linking PE with the Board of Directors and championing PE by managers, staff and committee/team chairs. CONCLUSION: This research generated insight on concrete approaches and strategies that hospitals can use to optimize PE for planning and improvement. On-going research is needed to understand how to recruit diverse patients and best balance blended consultation/collaboration approaches. PATIENT OR PUBLIC CONTRIBUTION: Three patient research partners with hospital PE experience informed study objectives and interview questions.

Hospital capacity for patient engagement in planning and improving health services: a cross-sectional survey.

BACKGROUND: Patient engagement (PE) in planning or improving hospital facilities or services is one approach for improving healthcare delivery and outcomes. To provide evidence on hospital capacity needed to support PE, we described the attributes of hospital PE capacity associated with clinical quality measures. METHODS: We conducted a cross-sectional survey of general and specialty hospitals based on the Measuring Organizational Readiness for Patient Engagement framework. We derived a PE capacity index measure, and with Multiple Correspondence Analysis, assessed the association of PE capacity with hospital type, and rates of hand-washing, C. difficile infection rates and 30-day readmission. RESULTS: Respondents (91, 66.4%) included general: < 100 beds (48.4%), 100+ beds (27.5%), teaching hospitals (11.0%) and specialty (13.2%) hospitals. Most featured PE in multiple clinical and corporate departments. Most employed PE in a range of Planning (design/improve facilities 94.5%, develop strategic plans 87.9%), Evaluation/Quality Improvement (accreditation 91.2%, develop QI plans 90.1%) and Service Delivery activities (develop information/communication aids 92.3%). Hospitals enabled PE with multiple supports (median 12, range 0 to 25), most often: 76.9% strategic plan recognizes PE, 74.7% patient/family advisory council, and 69.2% pool of patient volunteers; and least often: 30.0% PE staff, 26.4% PE funding and 16.5% patient reimbursement or 3.3% compensation. Hospitals employed a range of less (inform, consult) and more (involve, partner) active modes of engagement. Two variables accounted for 29.6% of variance in hospital PE capacity index measure data: number of departments featuring PE and greater use of active engagement modes. PE capacity was not associated with general hospital type or clinical quality measures. CONCLUSIONS: Hospitals with fewer resources can establish favourable PE conditions by deploying PE widely and actively engaging patients. Healthcare policy-makers, hospital executives and PE managers can use these findings to allocate PE resources. Future research should explore how PE modes and methods impact clinical outcomes.

Organizational capacity for patient and family engagement in hospital planning and improvement: interviews with patient/family advisors, managers and clinicians.

BACKGROUND: Patient and family engagement (PE) in healthcare planning and improvement achieves beneficial outcomes and is widely advocated, but a lack of resources is a critical barrier. Little prior research studied how organizations support engagement specifically in hospitals. OBJECTIVE: We explored what constitutes hospital capacity for engagement. METHODS: We conducted descriptive qualitative interviews and complied with criteria for rigour and reporting in qualitative research. We interviewed patient/family advisors, engagement managers, clinicians and executives at hospitals with high engagement activity, asking them to describe essential resources or processes. We used content analysis and constant comparison to identify themes and corresponding quotes and interpreted findings by mapping themes to two existing frameworks of PE capacity not specific to hospitals. RESULTS: We interviewed 40 patient/family advisors, patient engagement managers, clinicians and corporate executives from nine hospitals (two < 100 beds, four 100 + beds, three teaching). Four over-arching themes about capacity considered essential included resources, training, organizational commitment and staff support. Views were similar across participant and hospital groups. Resources included funding and people dedicated to PE and technology to enable communication and collaboration. Training encompassed initial orientation and project-specific training for patient/family advisors and orientation for new staff and training for existing staff on how to engage with patient/family advisors. Organizational commitment included endorsement from the CEO and Board, commitment from staff and continuous evaluation and improvement. Staff support included words and actions that conveyed value for the role and input of patient/family advisors. The blended, non-hospital-specific framework captured all themes. Hospitals of all types varied in the availability of funding dedicated to PE. In particular, reimbursement of expenses and compensation for time and contributions were not provided to patient/family advisors. In addition to skilled engagement managers, the role of clinician or staff champions was viewed as essential. CONCLUSION: The findings build on prior research that largely focused on PE in individual clinical care or research or in primary care planning and improvement. The findings closely aligned with existing frameworks of organizational capacity for PE not specific to hospital settings, which suggests that hospitals could use the blended framework to plan, evaluate and improve their PE programs. Further research is needed to yield greater insight into how to promote and enable compensation for patient/family advisors and the role of clinician or staff champions in supporting PE.

Ten things every neurologist needs to know about neuropsychological assessments and interventions in people with epilepsy.

This paper describes 10 core features of a neuropsychological assessment with the aim of helping neurologists understand the unique contribution the evaluation can make within the wider context of diagnostic methods in epilepsy. The possibilities, limitations and cautions associated with the investigation are discussed under the following headings. (1) A neuropsychological assessment is a collaborative investigation. (2) Assessment prior to treatment allows for the accurate assessment of treatment effects. (3) The nature of an underlying lesion and its neurodevelopmental context play an important role in shaping the associated neuropsychological deficit. (4) Cognitive and behavioural impairments result from the essential comorbidities of epilepsy which can be considered as much a disorder of cognition and behaviour as of seizures. (5) Patients' subjective complaints can help us understand objective cognitive impairments and their underlying neuroanatomy, resulting in improved patient care. At other times, patient complaints reflect other factors and require careful interpretation. (6) The results from a neuropsychological assessment can be used to maximize the educational and occupational potentials of people with epilepsy. (7) Not all patients are able to engage with a neuropsychological assessment. (8) There are limitations in assessments conducted in a second language with tests that have been standardized on different populations from that of the patient. (9) Adequate intervals between assessments maximize sensitivity to meaningful change. (10) Patients should be fully informed about the purpose of the assessment and have realistic expectations of the outcome prior to referral.

Metrics of progress in the understanding and management of threats to Australian birds.

Although evidence-based approaches have become commonplace for determining the success of conservation measures for the management of threatened taxa, there are no standard metrics for assessing progress in research or management. We developed 5 metrics to meet this need for threatened taxa and to quantify the need for further action and effective alleviation of threats. These metrics (research need, research achievement, management need, management achievement, and percent threat reduction) can be aggregated to examine trends for an individual taxon or for threats across multiple taxa. We tested the utility of these metrics by applying them to Australian threatened birds, which appears to be the first time that progress in research and management of threats has been assessed for all threatened taxa in a faunal group at a continental scale. Some research has been conducted on nearly three-quarters of known threats to taxa, and there is a clear understanding of how to alleviate nearly half of the threats with the highest impact. Some management has been attempted on nearly half the threats. Management outcomes ranged from successful trials to complete mitigation of the threat, including for one-third of high-impact threats. Progress in both research and management tended to be greater for taxa that were monitored or occurred on oceanic islands. Predation by cats had the highest potential threat score. However, there has been some success reducing the impact of cat predation, so climate change (particularly drought), now poses the greatest threat to Australian threatened birds. Our results demonstrate the potential for the proposed metrics to encapsulate the major trends in research and management of both threats and threatened taxa and provide a basis for international comparisons of evidence-based conservation science.

Medidas de Progreso en el Entendimiento y el Manejo de las Amenazas que Enfrentan las Aves Australianas Resumen Aunque los métodos basados en evidencias se han vuelto muy comunes para la determinación del éxito de las medidas de conservación del manejo de los taxones amenazados, hoy en día no existen medidas estandarizadas para la evaluación del progreso de la investigación o el manejo. Desarrollamos cinco medidas para cumplir con esta necesidad que tienen los taxones amenazados y para cuantificar la necesidad de una mayor acción y un alivio efectivo de las amenazas. Estas medidas (falta de investigación, éxito de la investigación, falta de manejo, éxito del manejo y porcentaje de reducción de amenazas) pueden agregarse para examinar las tendencias de un taxón individual o las tendencias de las amenazas para múltiples taxones. Probamos la utilidad de estas medidas por medio de su aplicación en aves australianas amenazadas, que parece ser la primera vez que se evalúa el progreso en la investigación y en el manejo de amenazas para el caso de varios taxones amenazados dentro de un grupo faunístico a escala continental. Se ha realizado algún tipo de investigación sobre casi tres cuartas partes de las amenazas conocidas para los taxones, y hay un claro entendimiento de cómo aliviar casi la mitad de las amenazas con el impacto más alto. Se ha intentado algún tipo de manejo con casi la mitad de las amenazas. Los resultados del manejo variaron desde ensayos exitosos hasta la mitigación completa de la amenaza, incluso para un tercio de las amenazas de alto impacto. Tanto el progreso en la investigación como en el manejo tendió a ser mayor para los taxones que estaban siendo monitoreados, o que ocurrían en islas oceánicas. La depredación por gatos tuvo el puntaje más como amenaza potencial. Sin embargo, ha habido poco de éxito en la reducción del impacto de la depredación por gatos, así que ahora el cambio climático (particularmente la sequía) es la mayor amenaza para las aves amenazadas en Australia. Nuestros resultados demuestran el potencial que tienen las medidas propuestas de encapsular las tendencias más importantes en la investigación y en el manejo tanto de las amenazas como de los taxones amenazados y de proporcionar una base para comparaciones internacionales de la ciencia de la conservación basada en evidencias.

Do the plant host origins of Helicoverpa (Lepidoptera: Noctuidae) moth populations reflect the agricultural landscapes within which they are caught?

The use of Bt cotton varieties has greatly reduced the amount of conventional insecticides required to control lepidopteran pests, Helicoverpa armigera and Helicoverpa punctigera, in Australia, but the possibility that these moths might become resistant to Bt remains a threat. Consequently, a Resistance Management Plan, which includes the mandatory growing of refuge crops (pigeon pea and non-Bt cotton; both C3 plants), has been established for Bt cotton farmers. However, knowledge of the relative contributions made to overall moth populations from the many host origins (both C3 and C4 plants) available to these insects throughout cotton production regions remains limited, as do the scales of movement and spatial mixing of moths within and between these areas. This study used stable isotope signatures (in particular δ13C) to help identify where moths fed as larvae within separate cotton production regions which differed in their proportions of C3 and C4 host crops (e.g. cotton and sorghum, respectively). C3-derived moths predominated in the early season, but C4-derived moths increased in frequency later. The overall proportion of C4 moths was higher in H. armigera than in H. punctigera. Whilst the relative proportions of C3 and C4 moths differed between regions, no differences in such proportiorns were found at smaller spatial scales, nor were there significant correlations between crop composition and isotope signatures in moths. Overall, these results suggest that C4 host plants are likely to be very important in offsetting the development of Bt resistance in these insects and such influences may operate across multiple regions within a single growing season.

Engaging primary care physicians in care coordination for patients with complex medical conditions.

OBJECTIVE: To explore the dynamics of primary care physicians' (PCPs') engagement with the Seamless Care Optimizing the Patient Experience (SCOPE) project. DESIGN: Qualitative study using semistructured interviews. SETTING: Solo and small group primary care practices in urban Toronto, Ont. PARTICIPANTS: A total of 22 of the 29 SCOPE PCPs (75.8%) were interviewed 14 to 19 months after the initiation of SCOPE. METHODS: Qualitative semistructured interviews were conducted to examine influencing factors associated with PCPs' engagement in SCOPE. Transcripts were analyzed using a grounded theory-informed approach and key themes were identified. MAIN FINDINGS: The SCOPE project provided practical mechanisms through which PCPs could access information and connect with resources. Contextual and historical factors including strained relationships between hospital specialists and community PCPs and PCPs' feelings of responsibility, isolation, disconnection, and burnout influenced readiness to engage. Provision of clinically useful supports in a trusting, collaborative manner encouraged PCPs' engagement in newer, more collaborative ways of working. CONCLUSION: The SCOPE project provided an opportunity for PCPs to build meaningful relationships, reconnect to the broader health care system, and redefine their roles. For many PCPs, reestablishing connections reaffirmed their role in the system and enabled a more collaborative care model. Strategies for connecting community-based PCPs to the broader system need to consider contextual factors and the effects of new linkages and coordination on the identities and relationships of PCPs.

New Voices, New Power, New Ways of Working: Bringing integrated care to the National Health Service in England.

This issue of Healthcare Quarterly features the third and final instalment in a three-part series developed by Ontario's The Change Foundation featuring international perspectives on health service delivery models that improve system integration and ensure seamless services and better coordination. Part one featured Chris Ham, chief executive of the London-based King's Fund think tank, and part two featured Geoff Huggins, director for health and social care integration in Scotland. In this issue, Helen Bevan, chief transformation officer of England's National Health Service, discusses the radical shifts she'd like to see in how we approach integration.

Mechanisms, contexts and points of contention: operationalizing realist-informed research for complex health interventions.

BACKGROUND: The concept of "mechanism" is central to realist approaches to research, yet research teams struggle to operationalize and apply the concept in empirical research. Our large, interdisciplinary research team has also experienced challenges in making the concept useful in our study of the implementation of models of integrated community-based primary health care (ICBPHC) in three international jurisdictions (Ontario and Quebec in Canada, and in New Zealand). METHODS: In this paper we summarize definitions of mechanism found in realist methodological literature, and report an empirical example of a realist analysis of the implementation ICBPHC. RESULTS: We use our empirical example to illustrate two points. First, the distinction between contexts and mechanisms might ultimately be arbitrary, with more distally located mechanisms becoming contexts as research teams focus their analytic attention more proximally to the outcome of interest. Second, the relationships between mechanisms, human reasoning, and human agency need to be considered in greater detail to inform realist-informed analysis; understanding these relationships is fundamental to understanding the ways in which mechanisms operate through individuals and groups to effect the outcomes of complex health interventions. CONCLUSIONS: We conclude our paper with reflections on human agency and outline the implications of our analysis for realist research and realist evaluation.
