Navigation programs to support community-dwelling individuals with life-limiting illness: determinants of implementation.

BACKGROUND: As the Canadian population ages and the prevalence of chronic illnesses increases, delivering high-quality care to individuals with advanced life limiting illnesses becomes more challenging. Community-based navigation programs are a promising approach to address these challenges, but little is known about how these programs are successfully implemented to meet the needs of this population. This study sought to identify the key determinants that contribute to the successful implementation of these programs within Canada. METHODS: A qualitative study was undertaken to understand the implementation of eleven innovative, community-based navigation programs that aim to address the needs of individuals with life-limiting illnesses as they approach the end of life. The Consolidated Framework for Implementation Research (CFIR) guided the study design. Key informants (n = 23) within these programs took part in semi-structured interviews where they were asked to discuss how these programs are implemented. Data were analyzed using techniques employed in qualitative description. RESULTS: We identified key determinants of successful implementation within each CFIR domain. In the outer setting domain, participants emphasized the importance of filling gaps in care to meet client needs, developing strong relationships with clients and community-based organizations, and navigating relationships with healthcare providers. At the inner setting level, leadership support, staff compatibility, and available resources were identified as important factors. In terms of intervention characteristics, the ability to adapt was cited as a facilitator, whereas costs were identified as a barrier. For the characteristics of individuals, participants described the importance of having staff whose values align with the program, and who have the experience and skills necessary to work with complex clients. Finally, having strong champions and evaluation processes were highlighted as important process-oriented determinants of successful implementation. CONCLUSION: This study provides valuable insights into the determinants of successful implementation of community-based navigation programs in Canada. Understanding these determinants can guide the future development and integration of navigation programs to successfully meet the needs of those with life-limiting illnesses.

How do navigation programs address the needs of those living in the community with advanced, life-limiting Illness? A realist evaluation of programs in Canada.

BACKGROUND: We sought to identify innovative navigation programs across Canadian jurisdictions that target their services to individuals affected by life-limiting illness and their families, and articulate the principal components of these programs that enable them to address the needs of their clients who are living in the community. METHODS: This realist evaluation used a two-phased approach. First, we conducted a horizon scan of innovative community-based navigation programs across Canadian jurisdictions to identify innovative community-based navigation programs that aim to address the needs of community-dwelling individuals affected by life-limiting illness. Second, we conducted semi-structured interviews with key informants from each of the selected programs. Informants included individuals responsible for managing and delivering the program and decision-makers with responsibility and/or oversight of the program. Analyses proceeded in an iterative manner, consistent with realist evaluation methods. This included iteratively developing and refining Context-Mechanism-Outcome (CMO) configurations, and developing the final program theory. RESULTS: Twenty-seven navigation programs were identified from the horizon scan. Using specific eligibility criteria, 11 programs were selected for subsequent interviews and in-depth examination. Twenty-three participants were interviewed from these programs, which operated in five Canadian provinces. The programs represented a mixture of community (non-profit or volunteer), research-initiated, and health system programs. The final program theory was articulated as: navigation programs can improve client outcomes if they have supported and empowered staff who have the time and flexibility to personalize care to the needs of their clients. CONCLUSIONS: The findings highlight key principles (contexts and mechanisms) that enable navigation programs to develop client relationships, personalize care to client needs, and improve client outcomes. These principles include staff (or volunteer) knowledge and experience to coordinate health and social services, having a point of contact after hours, and providing staff (and volunteers) time and flexibility to develop relationships and respond to individualized client needs. These findings may be used by healthcare organizations - outside of navigation programs - to work towards more person-centred care.

What Are the Characteristics of the Parish Nursing Research Literature and How Can it Inform Parish Nurse Practice and Research in Canada? A Scoping Review.

BACKGROUND: Parish nursing is a specialized branch of professional nursing that promotes health and healing by integrating body, mind and spirit as a practice model. Parish nurses contribute to the Canadian nursing workforce by promoting individual and community health and acting as system navigators. Research related to parish nursing practice has not been systematically collated and evaluated. PURPOSE: This review seeks to explore, critically appraise and synthesize the parish nurse (PN) research literature for its breadth and gaps, and to provide recommendations for PN practice and research. METHODS: A scoping review was conducted using Levac and colleagues' procedures and Arksey and O'Malley's enhanced framework. The CINAHL, ProQuest and PubMed databases were comprehensively searched for original research published between 2008 and 2020. The final sample includes 43 articles. The Mixed Methods Appraisal Tool was used to critically assess literature quality. RESULTS: There is a significant gap in PN research from Canada and non-U.S. countries. Methodological quality is varied with weak overall reporting. The literature is categorized under three thematic areas: (1) practice roles of the PN, (2) role implementation, and (3) program evaluation research. Research that evaluates health promotion program interventions is prominent. CONCLUSIONS: More rigorous research methods and the use of reporting checklists are needed to support evidence-informed parish nursing practice. Building relationships among parish nurses, nursing researchers and universities could advance parish nursing research and improve evidence-based parish nursing practice. Research into the cost effectiveness, healthcare outcomes, and the economic value of PN practice is needed.

Achieving holistic, quality-of-life focused care: description of a Compassion Care Community initiative in Canada.

The compassionate community movement as both a public health approach and a social model of care for various life stages is gaining traction in Canada and elsewhere. One example is the Windsor-Essex Compassion Care Community (WECCC), an evidence-based model and set of tools to improve the quality of life, health and wellness of vulnerable and aging populations by identifying and addressing upstream and downstream social and other risks to physical and mental health. This paper presents findings from the WECCC pilot evaluation. The WECCC initiative provided one-on-one volunteer-supported quality of life assessment, resource navigation and goals support program (Catalyzing Community Connections). This was augmented with public education sessions on social connection and loneliness (Importance of Being Connected) for the broader population. The RE-AIM framework was used to frame evaluation of WECCC through the first 4 years. Questionnaires were used to evaluate participant outcomes related to implementation and effectiveness. Interviews and focus groups were completed to understand impacts. From 2017 to 2020, WECCC has engaged over 2,500 individuals, 65 organizations and 400 volunteers combined in both programs. Nearly all (82% to 95%) participants reported positive changes to health, quality of life and/or social connections. This developmental phase of a compassionate community initiative has allowed piloting of an evaluation framework focusing on reach, adoption, implementation and early signals of effectiveness and maintenance. This demonstration provides information on feasibility, acceptability and potential impacts of this type of over-arching community initiative.

The compassionate communities movement is a social and holistic approach to care that engages community members in caring for others. The movement is growing around the world. The philosophy is that all citizens benefit from participating in care for others who are aging, disabled, nearing end-of-life or struggling with determinants of health. The Windsor-Essex Compassion Care Community (WECCC) is a Canadian example of this model. WECCC seeks to improve the health of people at any stage of life by helping them to identify their life needs and goals and providing them support to meet them. The program has two core components: one-on-one volunteer-support for person-directed goals and navigation (Catalyzing Community Connections) and public education sessions about loneliness and social connection (Importance of Being Connected). Evaluation is a routine part of program delivery with questionnaires, interviews and focus groups used to understand the program's outcomes. From 2017 to 2020, WECCC has worked with over 2,500 individuals, 65 organizations and 400 volunteers. Satisfaction with the program is very high (95%). Nearly all participants reported positive changes to their quality of life (82%) and social connections (95%). Although pilot results are favorable, continued evaluation and stronger research designs are needed to comprehensively evaluate the WECCC program over time and to support growth and spread of the model.

Nurse-pharmacist collaborations for promoting medication safety among community-dwelling adults: A scoping review.

Background: Despite good evidence that supports improved clinical health outcomes and the cost effectiveness of nurse-pharmacist collaboration for promoting medication safety among adults in acute care settings, there is limited research in community settings. Objective: This scoping review examines, maps, and identifies gaps in the existing literature on nurse-pharmacist collaboration to augment medication safety among community-dwelling adults. Design: Setting(s): Community setting. Participants: This review consists of 3,464 participants across 23 studies. Methods: We used the enhanced Arksey and O'Malley framework by Levac and colleagues. Studies from MEDLINE, CINAHL, ProQuest, Scopus, and PubMed databases implementing medication safety through nurse-pharmacist collaboration for community-dwelling adults were included. We extracted data according to country of origin, intervention, and relevance to the current review. Results: Twenty-three studies were included in this review. Nurse-pharmacist collaborations in community settings are still evolving and are in a nascent form. Five sub-themes emerged from literature review of collaboration between nurses and pharmacists in community settings for medication safety. They are creating new opportunities to address gaps in community medication safety, enabling complementary interprofessional roles in medication safety, facilitating of efficient and cost-effective measures for medication safety, diverse nature of assessments done by nurses and pharmacists, and incohesive teams due to poor collaborative practices. Conclusions: Nurse-pharmacist collaborations in community settings improved disease management, prevented adverse drug events, and reduced hospitalizations. They resulted in early identification and correction of medication safety related issues, reduced wait periods to see general practitioners, and enhanced chronic disease self-management skills among community-dwelling adults. There is a need to improve existing systems and policies through research for sustaining such collaborations especially in community settings.

The little things are big: evaluation of a compassionate community approach for promoting the health of vulnerable persons.

BACKGROUND: Vulnerable persons are individuals whose life situations create or exacerbate vulnerabilities, such as low income, housing insecurity and social isolation. Vulnerable people often receive a patchwork of health and social care services that does not appropriately address their needs. The cost of health and social care services escalate when these individuals live without appropriate supports. Compassionate Communities apply a population health theory of practice wherein citizens are mobilized along with health and social care supports to holistically address the needs of persons experiencing vulnerabilities. AIM: The purpose of this study was to evaluate the implementation of a compassionate community intervention for vulnerable persons in Windsor Ontario, Canada. METHODS: This applied qualitative study was informed by the Consolidated Framework for Implementation Research. We collected and analyzed focus group and interview data from 16 program stakeholders: eight program clients, three program coordinators, two case managers from the regional health authority, one administrator from a partnering community program, and two nursing student volunteers in March through June 2018. An iterative analytic process was applied to understand what aspects of the program work where and why. RESULTS: The findings suggest that the program acts as a safety net that supports people who are falling through the cracks of the formal care system. The 'little things' often had the biggest impact on client well-being and care delivery. The big and little things were achieved through three key processes: taking time, advocating for services and resources, and empowering clients to set personal health goals and make authentic community connections. CONCLUSION: Compassionate Communities can address the holistic, personalized, and client-centred needs of people experiencing homelessness and/or low income and social isolation. Volunteers are often untapped health and social care capital that can be mobilized to promote the health of vulnerable persons. Student volunteers may benefit from experiencing and responding to the needs of a community's most vulnerable members.

Exploring the Impact of Health Care Provider Cultural Competence on New Immigrant Health-Related Quality of Life: A Cross-Sectional Study of Canadian Newcomers.

INTRODUCTION: New immigrants underutilize health care because of multiple barriers. Although culturally competent health care improves access, it is typically assessed by providers, not newcomers whose perceptions matter most. METHODOLOGY: Surveys that included measures of cultural competence and health-related quality of life (QOL) were completed by 117 new immigrants in Windsor, Ontario, Canada. A series of stepwise linear regression analyses were conducted to identify independent predictors of QOL and its four domains: physical health, psychological, social relationships, and environment. RESULTS: Our adjusted results suggest that experiences of discrimination was negatively associated with overall QOL (ß = -.313; p < .001) and its psychological (ß = -.318; p < .001), social (ß = -.177; p = .048), and environmental (ß = -.408; p < .001) domains. DISCUSSION: Discrimination negatively influences new immigrant QOL. Provider cultural competency training should emphasize the influence of provider discrimination on immigrant health and explore learners' values and biases.

Unpacking 'the cloud': a framework for implementing public health approaches to palliative care.

Designing and implementing population-based systems of care that address the social determinants of health, take action on multiple levels, and are guided by evidence-based principles is a pressing priority, and an international challenge. Aging persons are a priority demographic whose health needs span physical, psychosocial and existential care domains, increase in the last year of life, are often poorly coordinated and therefore remain unmet. Compassionate communities (CCs) are an example of a public health approach that fully addresses the holistic healthcare needs of those who are aging and nearing end of life. The sharing of resources, tools, and innovations among implementers of CCs is occurring globally. Although this can increase impact, it also generates complexity that can complicate robust evaluation. When initiating population health level projects, it is important to clearly define and organize concepts and processes that are proposed to influence the health outcomes. The Health Impact Change Model (HICM) was developed to unpack the complexities associated with the implementation and evaluation of a Canadian CC intervention. The HICM offers utility for citizens, leaders and decision-makers who are engaged in the implementation of population health level strategies or other social approaches to care, such as compassionate cities and age or dementia-friendly communities. The HICM's concepts can be adapted to address a community's healthcare context, needs, and goals for change. We share examples of how the model's major concepts have been applied in the development, evaluation and spread of a complex CC approach.

Investigating palliative care nurse attitudes towards medical assistance in dying: An exploratory cross-sectional study.

AIM: To investigate palliative care nurse attitudes towards medical assistance in dying. DESIGN: An exploratory cross-sectional study design. METHODS: A mailed letter recruited participants with data collection occurring on a secure online survey platform between November 2017-February 2018. Data analyses included descriptive and bivariate statistics and stepwise linear regression. RESULTS: Palliative care nurse attitudes towards medical assistance in dying were explained by perceived expertise in the social domain of palliative care, personal importance of religion/faith, professional importance of religion/faith, and nursing designation. CONCLUSION: This study reveals the perceived importance of religion, versus religious affiliation alone, as significant in influencing provider attitudes towards assisted dying. Further research is needed to understand differences in attitudes between Registered Nurses and Registered Practical Nurses and how the social domain of palliative care influences nurse attitude. IMPACT: Organizations must prioritize nursing input, encourage open interprofessional dialogue and provide support for ethical decision-making, practice decisions, and conscientious objection surrounding medical assistance in dying. Longitudinal nursing studies are needed to understand the impact of legislation on quality and person-centred end-of-life care and the emotional well-being/retention of palliative care nurses.

Compassionate collaborative care: an integrative review of quality indicators in end-of-life care.

BACKGROUND: Compassion and collaborative practice are individually associated with high quality healthcare. When combined in a compassionate collaborative care (CCC) practice framework, they are reported to improve health, strengthen care provision, and control health costs. Little is known about how to integrate and measure CCC, yet it is fundamentally applied in palliative and end-of-life care settings. This study aimed to identify quality indicators of CCC by systematically reviewing and synthesizing the current state of the palliative and end-of-life care literature. METHODS: An integrative review of the palliative and end-of-life care literature was conducted using Whittemore and Knafl's method. Donabedian's healthcare quality framework was applied in the data analysis phase to organize and display the data. The analysis involved an iterative process that applied a constant comparative method. RESULTS: The final literature sample included 25 articles. Patient and family-centered care emerged as a primary structure for CCC, with overarching values including empathy, sharing, respect, and partnership. The analysis revealed communication, shared decision-making, and goal setting as overarching processes for achieving CCC at end-of-life. Patient and family satisfaction, enhanced teamwork, decreased staff burnout, and organizational satisfaction are exemplars of outcomes that suggest high quality CCC. Specific quality indicators at the individual, team and organizational levels are reported with supporting exemplar data. CONCLUSIONS: CCC is inextricably linked to the inherent values, needs and expectations of patients, families and healthcare providers. Compassion and collaboration must be enacted and harmonized to fully operationalize and sustain patient and family-centered care in palliative and end-of-life practice settings. Towards that direction, the quality indicators that emerged from this integrative review provide a two-fold application in palliative and end-of-life care. First, to evaluate the existing structures, processes, and outcomes at the patient-family, provider, team, and organizational levels. Second, to guide the planning and implementation of team and organizational changes that improve the quality delivery of CCC.

Reducing the "cost of caring" in cancer care: Evaluation of a pilot interprofessional compassion fatigue resiliency programme.

Compassion fatigue (CF) is a combination of secondary traumatic stress and burnout. Empathy becomes depleted among professional caregivers due to repeated exposure to emotional pain. Negative effects include decreased general wellbeing, impaired caregiver health and diminished team functioning. Intervention is needed to support caregiver quality of life and team relationships in high-stress work environments. This pilot study evaluated the impact of a pilot CF resiliency (CFR) programme on interprofessional staff at a regional cancer centre. An embedded experimental mixed-methods design was employed to evaluate a 6-week formalised CFR intervention. We measured CF satisfaction, burnout, clinical stress and silencing responses pre- and post-intervention. Focus group and individual interviews were conducted mid-programme and at end-programme completion to understand participants' views about how the programme affected their experiences of CF. Qualitative and quantitative data were analysed separately and merged to produce the overall findings. Participants reported reduced clinical stress at programme completion (t = 3.5; p = .005). This finding may be explained by participants' ability to identify signs and symptoms of CF and engage in self-care and mindfulness activities. Further larger studies are needed to evaluate the long-term effects of CFR programmes on caregiver and organisational wellbeing.

Leaders' experiences and perceptions implementing activity-based funding and pay-for-performance hospital funding models: A systematic review.

INTRODUCTION: Providing cost-effective, accessible, high quality patient care is a challenge to governments and health care delivery systems across the globe. In response to this challenge, two types of hospital funding models have been widely implemented: (1) activity-based funding (ABF) and (2) pay-for-performance (P4P). Although health care leaders play a critical role in the implementation of these funding models, to date their perspectives have not been systematically examined. PURPOSE: The purpose of this systematic review was to gain a better understanding of the experiences of health care leaders implementing hospital funding reforms within Organisation for Economic Cooperation and Development countries. METHODS: We searched literature from 1982 to 2013 using: Medline, EMBASE, CINAHL, Academic Search Complete, Academic Search Elite, and Business Source Complete. Two independent reviewers screened titles, abstracts and full texts using predefined criteria. We included 2 mixed methods and 12 qualitative studies. Thematic analysis was used in synthesizing results. RESULTS: Five common themes and multiple subthemes emerged. Themes include: pre-requisites for success, perceived benefits, barriers/challenges, unintended consequences, and leader recommendations. CONCLUSIONS: Irrespective of which type of hospital funding reform was implemented, health care leaders described a complex process requiring the following: organizational commitment; adequate infrastructure; human, financial and information technology resources; change champions and a personal commitment to quality care.

Exploring new graduate nurse confidence in interprofessional collaboration: a mixed methods study.

BACKGROUND: Confidence is required for effective engagement in interprofessional collaboration. New graduate nurses often lack confidence in interprofessional interactions, and this may compromise the delivery of safe and effective healthcare. OBJECTIVES: The overall objective of this study was to explore new graduate nurse confidence in interprofessional collaboration. DESIGN: An explanatory sequential mixed methods design was used. METHODS: New graduate nurses from Ontario, Canada (N=514) completed a cross-sectional descriptive survey in 2012. The survey measured perceived confidence in interprofessional collaboration, and it included items that were proposed to have a relationship with new graduate nurse confidence in interprofessional collaboration. Follow-up qualitative telephone interviews were conducted with 16 new graduate nurses. RESULTS: The quantitative findings suggested that several factors have a positive relationship with new graduate nurse confidence in interprofessional collaboration: availability and accessibility of manager, availability and accessibility of educator, number of different disciplines worked with daily, number of team strategies, and satisfaction with team. The qualitative phase supported the quantitative findings and also provided new information about factors that facilitated and challenged new graduate nurse confidence when engaging in interprofessional collaboration. The facilitators were: experience, knowledge, respect, supportive relationships, and opportunities to collaborate. Challenges included: lack of experience, lack of knowledge, communication challenges, and balancing practice expectations. The overall findings relate to team and organizational support, and new graduate nurse development. CONCLUSION: Interventions that provide support for interprofessional collaboration at the team and organizational levels, and develop new graduate nurse knowledge and experiences regarding collaborative practice, are essential for enhancing new graduate nurse confidence in interprofessional collaboration.

A mixed methods exploration of the team and organizational factors that may predict new graduate nurse engagement in collaborative practice.

Although engagement in collaborative practice is reported to support the role transition and retention of new graduate (NG) nurses, it is not known how to promote collaborative practice among these nurses. This mixed methods study explored the team and organizational factors that may predict NG nurse engagement in collaborative practice. A total of 514 NG nurses from Ontario, Canada completed the Collaborative Practice Assessment Tool. Sixteen NG nurses participated in follow-up interviews. The team and organizational predictors of NG engagement in collaborative practice were as follows: satisfaction with the team (ß = 0.278; p = 0.000), number of team strategies (ß = 0.338; p = 0.000), participation in a mentorship or preceptorship experience (ß = 0.137; p = 0.000), accessibility of manager (ß = 0.123; p = 0.001), and accessibility and proximity of educator or professional practice leader (ß = 0.126; p = 0.001 and ß = 0.121; p = 0.002, respectively). Qualitative analysis revealed the team facilitators to be respect, team support and face-to-face interprofessional interactions. Organizational facilitators included supportive leadership, participation in a preceptorship or mentorship experience and time. Interventions designed to facilitate NG engagement in collaborative practice should consider these factors.

An integrative review of the factors influencing new graduate nurse engagement in interprofessional collaboration.

AIM: To analyse critically the barriers and facilitators to new graduate nurse engagement in interprofessional collaboration. BACKGROUND: The acculturation of new graduate nurses must be considered in strategies that address the global nursing shortage. Interprofessional collaboration may support the transition and retention of new graduate nurses. DESIGN: Whittemore and Knafl's revised framework for integrative reviews guided the analysis. DATA SOURCES: A comprehensive multi-step search (published 2000-2012) of the North American interprofessional collaboration and new graduate literature indexed in the CINAHL, Proquest, Pubmed, PsychINFO and Cochrane databases was performed. A sample of 26 research and non-research reports met the inclusion criteria. REVIEW METHODS: All 26 articles were included in the review. A systematic and iterative approach was used to extract and reduce the data to draw conclusions. RESULTS: The analysis revealed several barriers and facilitators to new graduate engagement in interprofessional collaboration. These factors exist at the individual, team and organizational levels and are largely consistent with conceptual and empirical analyses of interprofessional collaboration conducted in other populations. However, knowledge and critical thinking emerged as factors not identified in previous analyses. CONCLUSION: Despite a weak-to-moderate literature sample, this review suggests implications for team and organizational development, education and research that may support new graduate nurse engagement in IPC.

Embolization of a type 2 endoleak through catheterization of a hypogastric branched stent-graft.

In contrast to internal iliac artery (IIA) occlusion, the use of branch stent-graft (BSG) has been developed as an efficient adjunct in preserving pelvic blood flow. However, the risk of post-procedural type 2 endoleak (EL) remains. We present the case of an 80-year-old man with a juxtarenal aneurysm extending to both common and IIA. The patient was treated with a fenestrated device and a left BSG after embolization of the right IIA branches. At 6 months, the persistence of a type 2 EL associated with aneurysm growth mandated EL embolization through the BSG with a good result. Technical issues are discussed.

Comparing the psychological stress between non-smoking patients and smoking patients who experience abrupt smoking cessation during hospitalization for acute myocardial infarction: a pilot study.

BACKGROUND: Stress is an untoward condition in patients with acute myocardial infarction (AMI). Abrupt nicotine withdrawal is associated with increased symptoms of stress. However, little is known about the impact of smoking cessation on the psychological indicators of stress among hospitalized AMI patients. PURPOSE: In this pilot study we compared the psychological stressors between non-smoking AMI patients and smoking patients who abruptly ceased smoking following admission to the CCU. METHODS: A cross-sectional survey was piloted on a sample of 57 AMI patients (29 smokers and 28 nonsmokers) on the second day of admission to the CCU. Psychological stress was measured using the Profile of Mood States and the Insomnia Severity Index. RESULTS: Multivariate analysis of covariance (MANCOVA) suggested that after adjusting for age, smokers experienced significantly higher overall levels of stress than non-smokers (F = 3.13; p = 0.016). Post-hoc analyses suggested that scores of depression (p = 0.033), anxiety (p = 0.007), and anger (p = 0.017) were particularly higher among smokers, as compared to non-smokers. However, the two groups were not different with regard to their scores on fatigue (p = 0.528) and insomnia (p = 0.299). CONCLUSIONS: Abrupt smoking cessation may expose patients admitted with AMI symptoms to higher levels of psychological stress. Given the potential damaging impact of psychological stressors on the physical outcomes of these patients, these findings demonstrate the need for continued assessment and research related to the management of nicotine withdrawal following AMI.

Contemporary analysis of descending thoracic and thoracoabdominal aneurysm repair: a comparison of endovascular and open techniques.

BACKGROUND: Endovascular repair of thoracic aneurysm has demonstrated low risks of mortality and spinal cord ischemia (SCI), but few large series have been published on endovascular thoracoabdominal aneurysm repair, and reports suffer from a lack of accurate comparison with similar open surgical procedures. METHODS AND RESULTS: A consecutive cohort of patients with thoracic and thoracoabdominal aneurysms treated electively with endovascular repair (ER) or surgical repair (SR) techniques between 2001 and 2006 were analyzed. The association between repair technique and SCI was evaluated with univariable analysis. Adjustments for potential confounders and for the propensity to receive ER or SR were also performed in multivariable analysis. A total of 724 patients (352 ER, 372 SR) underwent repair. The mean age was 67 years, and 65% were male. ER patients were on average 9 years older (P<0.001), had more comorbid conditions, and more frequently had prior distal repair (P<0.001) or underwent a type I or IV repair. SR patients more commonly had chronic dissection or required type II or type III repairs (P<0.001). Mortality at 30 days (5.7% ER versus 8.3% SR, P=0.2) and 12 months (15.6% ER versus 15.9% SR, P=0.9) was similar. A borderline difference in SCI was found between repair techniques: 4.3% of ER and 7.5% of SR patients (P=0.08) had SCI. In patients with ER, prior distal aortic operation was associated with the development of SCI in univariable analysis (odds ratio 4.1, 95% confidence interval 1.4 to 11.7). Multivariable analysis showed that the type of required repair (type I, II, III, or IV) was the primary factor associated with the development of SCI in ER and SR patients. CONCLUSIONS: No significant difference in the incidence of mortality or SCI was found between ER and SR techniques. The strongest factor associated with SCI remains the extent of the disease. Further studies are indicated to compare ER with patients considered eligible for SR.

Endovascular treatment of thoracoabdominal aortic aneurysms.

OBJECTIVE: To establish the safety and efficacy of endovascular repair of thoracoabdominal aortic aneurysms. METHODS: Between May 2004 and February 2006, patients with thoracoabdominal aneurysms considered high risk for conventional surgery were enrolled in a prospective trial to evaluate a novel endovascular grafting system. Devices were custom designed for each patient using high-resolution computed tomography. Patient data included mortality, morbidity, procedural details, and surrogate end points for endovascular repair. These were collected at hospital discharge and at 1, 6, and 12 months. RESULTS: Seventy-three patients underwent endovascular repair of thoracoabdominal aortic aneurysms for type I, II, or III (n = 28), or for type IV (n = 45) thoracoabdominal aneurysms. Mean aneurysm size was 7.1 cm (range 4.5-11.3 cm). General anesthesia was used in 47% of patients and regional anesthesia in 53%. There were no conversions to open surgery nor ruptures post-treatment. Technical success was achieved in 93% of patients (68/73). Thirty-day mortality was 5.5% (4/73). Major perioperative complications occurred in 11 (14%) patients and included paraplegia (2.7%, 2/73), new onset of dialysis (1.4%, 1/73), prolonged ventilator support (6.8%, 5/73), myocardial infarction (5.5%, 4/73), and minor hemorrhagic stroke (1.4%; 1/72). A majority of patients had no complications. Mean length of stay was 8.6 days. At follow-up, 6 deaths had occurred. There were no instances of stent migration nor aneurysmal growth. CONCLUSIONS: Endovascular repair of aortic aneurysms involving the visceral segment in nonsurgical candidates is feasible. Known complications of repair are not eliminated, but morbidity and mortality appeared low relative to the high-risk population studied. Further refinement of device design, delivery technique, and patient selection is ongoing. Assessment of durability will require longer follow-up.

Beyond the aortic bifurcation: branched endovascular grafts for thoracoabdominal and aortoiliac aneurysms.

OBJECTIVES: To evaluate the use of novel technology to treat complex aortic aneurysms involving branches that provide critical end-organ blood supply. METHODS: A prospective study was conducted in patients with thoracoabdominal, suprarenal, or common iliac aneurysms (TAA, SRA, or CIA) at high risk for open surgical repair. An endovascular graft using the Zenith platform was customized to fit patient anatomy (TAA or SRA) and combined with Jomed balloon-expandable stent-grafts. Prefabricated hypogastric branches were used with a Zenith abdominal aortic aneurysm (AAA) or Fluency self-expanding fenestrated device in conjunction with a self-expanding stent-graft. Analyses were conducted in accordance with the endovascular aneurysm reporting standards document. Follow-up studies occurred at discharge, 1, 6, and 12 months, and included computed tomography and duplex ultrasound scans, and flat plate radiography. RESULTS: Fifty patients were treated (9 TAA, 20 SRA, 21 CIA). The mean aneurysm size was 7.6 cm (TAA), 7.2 cm (SRA), and 6.1 cm AAA size associated with a mean CIA size of 3.8 cm. Bilateral CIA aneurysms were present in 86% (18/21) of patients with CIA aneurysms. Perioperative mortality was 2% (1/50) and resulted from a myocardial infarction after a planned conduit and iliac endarterectomy required for device access. Five late deaths occurred (2 TAA, 2 SRA, 1 CIA), three of which (2 TAA, 1 SRA) were aneurysm related. Failure to access internal iliac arteries occurred in three cases, and two late hypogastric branch thromboses occurred. No visceral branches were lost acutely or occluded during follow-up. Sac shrinkage (>5 mm) was noted in 65% of patients at 6 months and in all patients (10/10) by 12 months. There were no ruptures or conversions, but nine patients required secondary interventions. CONCLUSIONS: Branch vessel technology has made it technically feasible to preserve critical end-organ perfusion in the setting of CIA, SRA, and TAA aneurysms. The relatively low acute mortality rate and lack of short-term branch vessel loss are encouraging and merit further investigation. These advances have the potential to markedly diminish the complications associated with conventional management of complex aneurysms.
