A strengths-based qualitative exploration of critical care nurses' reasons for remaining in critical care.

AIMS: Globally, the nursing shortage is a growing concern. Much of the research on retention of nurses focuses on the experience of those who left positions. In this study, we set out to listen to critical care nurses (CCRNs) who have chosen to remain in their positions to understand the factors retaining them in critical care. DESIGN: This interpretive descriptive study was guided by the following research question: 'what factors influence CCRN's decision to continue to work in critical care?' METHODS: Digitally recorded interviews and a focus group were conducted between July 2022 and January 2023 using a semi-structured, strengths-based interview guide with CCRNs from three critical care units at a tertiary hospital in a city in a central Canadian province. Transcribed interviews were analysed using open, axial and selective coding and constant comparative analysis. RESULTS: Twenty-two CCRNs participated in interviews and three in a focus group. The theme of Respect, demonstrated through the interconnected concepts of Working to Full Scope, Team, Rotations and Compensation was identified. Working to Full Scope was described as providing nursing care aligned with how each nurse envisions what nursing is. Being part of a Team led by strong nurse leaders that provides opportunities and supports the sharing of their perspectives was also found. Respect was also found to be demonstrated through Rotations that recognize that work is one part of these nurses' lives. Compensation that reflects the increased education, knowledge and skills required in critical care was the final concept of Respect. CONCLUSION: Organizations should focus their efforts across the identified concepts to demonstrate Respect for CCRNs and retain them. IMPLICATIONS FOR PRACTICE: The findings of this study provide ways to support the retention of CCRNs. IMPACT: This research will have an impact on nursing leaders by providing tangible ways to retain CCRNs. REPORTING METHOD: Reporting of this work was guided by the Standards for Reporting Qualitative Research. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Validation of the Emory Risk Score in the Transcatheter Aortic Valve Implantation Population: A Canadian Perspective.

Background: Permanent pacemaker (PPM) implantation may be indicated post-transcatheter aortic valve implantation (TAVI). The Emory Risk Score (ERS) is a validated predictive risk score of the need for a PPM post-TAVI using a balloon-expandable valve. Our objectives were to determine the validity of the ERS in our local TAVI population with both balloon-expandable and self-expanding valves and to identify additional electrocardiographic (ECG) parameters predictive of the need for a PPM post-TAVI. Methods: Retrospective chart and electronic database reviews were performed to collect demographic and procedural information. Two expert readers reviewed all ECGs. Independent factors associated with PPM implantation were examined with multivariable logistic regression via a stepwise selection process with calculation of the area under the receiver operating characteristic curve to assess model discrimination. Results: The overall PPM implantation rate was 11.7%; rates were 9% for the Sapien 3 valves, 10% for the Evolut Pro valves, and 17% for the Evolut R valves. The ERS was found to not be predictive of need for PPM post-TAVI for the entire cohort. Right bundle branch block was the only ERS parameter independently associated with new PPM implant (8.5% vs 25%, odds ratio = 3.59, P = 0.01). No additional ECG parameters met the criteria for statistical significance. Conclusions: The poor predictive value of the ERS in determining the need for a PPM post-TAVI in our patient population suggests that further refinement of a formula (or risk-calculator) is warranted. Identification of a precise risk-calculator is likely to facilitate patient mobilization and reduce inpatient healthcare resource utilization.

Introduction: L'implantation d'un stimulateur cardiaque permanent (SCP) peut être indiquée après l'implantation valvulaire aortique par cathéter (post-IVAC). L'Emory Risk Score (ERS) est un score de prédiction du risque validé de la nécessité d'un SCP post-IVAC au moyen d'une valve expansible par ballonnet. Nous avions pour objectif de déterminer la validité de l'ERS auprès de notre population ayant eu une IVAC soit par valve expansible par ballonnet ou valve auto-expansible, et de déterminer d'autres paramètres électrocardiographiques (ECG) prédictifs de la nécessité d'un SCP post-IVAC. Méthodes: Nous avons réalisé des revues rétrospectives de dossiers et de bases de données électroniques pour collecter les données démographiques et interventionnelles. Deux experts ont lu et interprété tous les ECG. Les facteurs indépendants associés à l'implantation du SCP ont été examinés en effectuant la régression logistique multivariée par processus de sélection pas-à-pas au moyen du calcul de la surface sous la courbe caractéristique d'efficacité du récepteur afin d'évaluer la discrimination du modèle. Résultats: Le taux global d'implantation d'un SCP était de 11,7 % ; les taux étaient de 9 % pour les valves Sapien 3, de 10 % pour les valves Evolut Pro et de 17 % pour les valves Evolut R. Nous avons observé que l'ERS ne permettait pas de prédire si l'implantation d'un SCP post-IVAC était nécessaire pour la cohorte entière. Le bloc de branche droit était le seul paramètre de l'ERS indépendamment associé à la nouvelle implantation d'un SCP (8,5 % vs 25 %, rapport de cotes = 3,59, P = 0,01). Aucun autre paramètre ECG ne satisfaisait au critère de signification statistique. Conclusions: La faible valeur prédictive de l'ERS à déterminer la nécessité d'un SCP post-IVAC au sein de notre population de patients montre que des améliorations de la formule (ou calculateur de risques) sont justifiées. L'identification d'un calculateur de risques précis devrait favoriser l'adhésion des patients et réduire l'utilisation des ressources en soins de santé en milieu hospitalier.

Differences in coronary artery disease complexity and associations with mortality and hospital admissions among First Nations and non-First Nations patients undergoing angiography: a comparative retrospective matched cohort study.

BACKGROUND: First Nations people are more likely than the general population to experience long-term adverse health outcomes after coronary angiography. Our aim was to quantify the extent of coronary artery disease among First Nations and non-First Nations patients undergoing angiography to investigate differences in coronary artery disease and related health disparities. METHODS: We conducted a retrospective matched cohort study to compare health outcomes of First Nations and non-First Nations adult patients (> 18 yr) who underwent index angiography between Apr. 1, 2008, and Mar. 31, 2012, in Manitoba, Canada. The SYNTAX Score was used to measure and compare severity of coronary artery disease between groups. Primary outcomes of all-cause and cardiovascular mortality were compared between groups using Cox proportional hazard models adjusted by SYNTAX Score results and weighted by the inverse probability of being First Nations. Secondary outcomes included all-cause and cardiovascular-related hospital admissions. RESULTS: The cohort consisted of 277 matched pairs of First Nations and non-First Nations patients undergoing angiography; the average age of patients was 56.0 (standard deviation 11.7) years. The median SYNTAX Score results and patient distributions across categories in the matched paired cohort groups were not significantly different. Although proportionally First Nations patients showed worse health outcomes, mortality risks were similar in the weighted sample, even after controlling for revascularization and SYNTAX Score results. Secondary outcomes showed that adjusted risks for hospital admission for acute myocardial infarction (adjusted hazard ratio [HR] 3.03, 95% confidence interval [CI] 1.40-6.55) and for congestive heart failure (adjusted HR 3.84, 95% CI 1.37-10.78) were significantly higher among First Nations patients in the weighted sample. INTERPRETATION: The extent of coronary artery disease among matched cohort groups of First Nations and non-First Nations patients appears similar, and controlling for baseline sociodemographic characteristics, coronary artery disease risk factors and SYNTAX Score results explained higher mortality risk and most hospital admissions among First Nations patients. Although there is a need to decrease risk factors for coronary artery disease among First Nations populations, addressing individuals' behaviour without considering root causes underlying risk factors for coronary artery disease will fail to decrease health outcome disparities among First Nations patients undergoing angiography.

Cardiovascular Medication Use and Long-Term Outcomes of First Nations and Non-First Nations Patients Following Diagnostic Angiography: A Retrospective Cohort Study.

Background In Canada, First Nations (FN) people are at greater risk of mortality than the general population following index angiography. This disparity has not been investigated while considering guideline-recommended cardiovascular medication use. Methods and Results Retrospective analysis of administrative health data investigated patterns of medication dispensation during the first year after index angiography among patients in Manitoba, Canada. Medication possession ratios (MPRs) reflecting the percentage of days in which medications were supplied were calculated separately for ß-blockers, angiotensin-converting enzyme inhibitors, statins, and antiplatelets (clopidogrel). Patients were assigned to 1 of 4 categories: (1) not dispensed (0% MPR), (2) low (1-39% MPR), (3) intermediate (40-79% MPR), (4) high (≥80% MPR). Cox regression models that adjusted for MPR categories were used to explore the association between FN patients and both 5-year all-cause mortality and cardiovascular mortality. FN patients were less likely to have an intermediate MPR (odds ratio: 0.75; 95% CI, 0.57-0.99) or a high MPR (odds ratio: 0.64; 95% CI, 0.50-0.81) for statin medications than non-FN patients. FN patients also had higher adjusted risks of all-cause and cardiovascular mortality than non-FN patients (hazard ratio, all-cause: 1.54 [95% CI, 1.25-1.89]; cardiovascular: 1.62 [95% CI, 1.16-2.25]). Conclusions FN status was independently associated with intermediate and high MPRs for statins during the first year following index angiography among patients with known ischemic heart disease. Differences in MPR categories did not explain the disparity in all-cause and cardiovascular mortality between the 2 populations. Reduction of cardiovascular disparities may be best addressed using primary prevention strategies that include decolonizing policies and practices.

Health Outcome and Follow-up Care Differences Between First Nation and Non-First Nation Coronary Angiogram Patients: A Retrospective Cohort Study.

BACKGROUND: First Nations (FN) people experience high rates of ischemic heart disease (IHD) morbidity and mortality. Increasing access to angiography may lead to improved outcomes. We compared various outcomes and follow-up care post-index angiography between FN and non-FN patients. METHODS: All index angiography patients in Manitoba were identified between April 1, 2000 and March 31, 2009 and categorized into acute myocardial infarction (AMI) or non-AMI groups based on whether their angiogram occurred within 7 days of an AMI. Cox proportional hazard models estimated associations between FN status and outcomes related to mortality, subsequent hospitalizations, revascularizations, and physician visits. RESULTS: Cardiovascular mortality was higher among FN patients in the non-AMI group (hazard ratio [HR] = 1.50, 95% confidence interval [CI], 1.17-1.94) and in the AMI group (HR = 1.57, 95% CI, 1.05-2.35). FN patients were also more likely to have a subsequent hospitalization for AMI (HR = 2.26, 95% CI, 1.79-2.85) in the non-AMI group. FN patients in the non-AMI group were less likely to receive percutaneous coronary intervention (HR = 0.85, 95% CI, 0.73-0.99) and more likely to undergo coronary artery bypass graft (HR = 1.26, 95% CI, 1.10-1.45). FN patients in both groups were less likely to visit a cardiologist/cardiac surgeon, internal medicine specialist, or family physician within 3 months and 1 year of angiography. CONCLUSIONS: Cardiovascular health and follow-up care outcomes of FN and non-FN patients who undergo angiography are not the same. Addressing Indigenous determinants of health are necessary to improve cardiovascular outcomes.

Index coronary angiography use in Manitoba, Canada: a population-level descriptive analysis of First Nations and non-First Nations recipients.

OBJECTIVES: To investigate recipient characteristics and rates of index angiography among First Nations (FN) and non-FN populations in Manitoba, Canada. SETTING: Population-based, secondary analysis of provincial administrative health data. PARTICIPANTS: All adults 18 years or older who received an index angiogram between 2000/2001 and 2008/2009. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Descriptive statistics for age, sex, income quintile by rural and urban residency and Charlson Comorbidity Index for FN and non-FN recipients. (2) Annual index angiogram rates for FN and non-FN populations and among those rates of 'urgent' angiograms based on acute myocardial infarction (AMI)-related hospitalisations during the previous 7 days. (3) Proportions of people who did not receive an angiogram in the 20 years preceding an ischaemic heart disease (IHD) diagnosis or a cardiovascular death; stratified by age (<65 or ≥65 years old). RESULTS: FN recipients were younger (56.3vs63.8 years; p<0.0001) and had higher Charlson Comorbidity scores (1.32vs0.78; p<0.001). During all years examined, index angiography rates were lower among FN people (2.67vs3.33 per 1000 population per year; p<0.001) with no notable temporal trends. Among the index angiogram recipients, a higher proportion was associated with an AMI-related hospitalisation in the FN group (28.8%vs25.0%; p<0.01) and in both groups rates significantly increased over time. FN people who died from cardiovascular disease or were older (65+years old) diagnosed with IHD were more likely to have received an angiogram in the preceding 20-30 years (17.8%vs12.5%; p<0.01 and 50.9%vs49.5%; p<0.03, respectively). FN people diagnosed with IHD who were under the age of 65 were less likely to have received an angiogram (47.8%vs53.1%; p<0.01) CONCLUSIONS: Index angiogram use differences are suggested between FN and non-FN populations, which may contribute to reported IHD disparities. Investigating factors driving these rates will determine any association between ethnicity and angiography services.

Exploring the Perceptions and Health Behaviours of Patients Following an Elective Ad-hoc Percutaneous Coronary Intervention: A Qualitative Study.

RESULTS: Participants expressed uncertainty about their future health and feared disease recurrence, which appeared to provide motivation for adopting a healthier lifestyle. Although two participants voiced the belief that the elective PCI cured their disease, this perception did not appear to influence their engagement in risk reduction behaviours. However, systemfactors such as a lack of information, direction, and/or support from health care providers appeared to play a limiting role in their ability to move forward with lifestyle change. BACKGROUND: Elective ad-hoc percutaneous coronary interventions (PCIs) are increasingly used to manage the symptoms of coronary artery disease (CAD). However, we have limited understanding of the patients' experiences and health behaviours post-procedure. PURPOSE: Explore the factors that influence the perceptions and health behaviours of patients after elective ad-hoc PCI. METHODS: This interpretive descriptive study used purposive sampling to recruit participants (N = 10) aged 44 to 65 years following an elective ad-hoc PCI from a cardiac catheterization laboratory at a tertiary centre in Winnipeg, MB. Participants were interviewed 11 to 35 days following their procedure. Recruitment continued until no new substantive themes emerged. The Health Belief Model provided the frameworkfor developing, exploring, interpreting, and analyzing the data. PRACTICE IMPLICATIONS: Nurses have a key role in the education of patients and in providingpatient-centred care that supports lifestyle change. Nurses need to develop strategies that decrease barriers to engaging in risk reduction behaviours following elective ad-hoc PCI if patients are to experience improved health and longevity.

Survey of Canadian critical care nurses' experiences of conflict in intensive care units.

The purpose of this study was to enhance our understanding of Canadian critical care nurses' experiences of and responses to situations of conflict in the ICU. Through a 35-item web-based survey, members of the Canadian Association of Critical Care Nurses were asked questions regarding the types, causes and frequency of conflict experienced, the nursing interventions found most helpful in situations of conflict, and the resources found most helpful in responding to situations of conflict. A total of 241 nurses responded to the survey. The mean age of the nurses was 43 years, and the majority were female (89.2%), direct care providers (66.4%), with greater than 11 years of experience in critical care (58.3%), and working in medical/surgical ICUs (66.4%) in tertiary care hospitals (67.2%). Approximately 51% of the nurses reported being involved in at least one situation of conflict related to the management of a patient in the last week worked. The most common types of conflict encountered were disagreements between the team and family (46.5%) or within the team (35.3%). The nurses acknowledged the importance of clear, consistent and honest communication with patients and families when conflict arises and rank-ordered the resources found most helpful to patients, families, and nurses in conflict situations. Implications for practice and education are discussed and recommendations for future research are outlined.

Critical care nurses' perceptions of their roles in family-team conflicts related to treatment plans.

Conflict over treatment plans is a cause of concern for those working in critical care environments. The purpose of this study was to explore and describe critical care nurses' perceptions of their roles in situations of conflict between family members and health-care providers in intensive care units. Using a qualitative descriptive design, 12 critical care nurses were interviewed individually and 4 experienced critical care nurses participated in focus group interviews. The roles described by the nurses were as follows: providing safe, competent, quality care to patients; building or restoring relationships of trust with families; and supporting other nurses. The nurses highlighted the level of stress when conflict arises, the need to be cautious in providing care and communicating with family members, and the need for support for nurses. More research related to working in situations of conflict is required, as is enhanced education for critical care nurses.

Angina following percutaneous coronary intervention: in-stent restenosis.

Percutaneous coronary intervention (PCI) represents a technical advance in the treatment of coronary artery disease. However, it is not without risks both during and after the procedure. In-stent restenosis (ISR) is the most common complication following PCI. Individuals who experience angina associated with ISR often fail to recognize its seriousness and, therefore, do not respond appropriately to the situation. Individuals with ISR are vulnerable to the consequences of angina, including increased morbidity and mortality, as well as a decreased health-related quality of life. In this article, the authors review the risks for developing ISR, the pathophysiology of angina related to ISR, and the challenges that face patients who develop recurrent angina post-PCI. Cardiovascular nurses play a critical role in the clinical management and education of patients following PCI. The provision of post-PCI follow-up care is key to identifying, managing, and supporting patients with recurrent angina.

Improving outcomes following elective percutaneous coronary intervention: the key role of exercise and the advanced practice nurse.

Percutaneous coronary intervention (PCI) is a safe, effective, non-surgical treatment for coronary artery disease (CAD). The demand for PCI has increased exponentially since the 1980s and it has become the treatment of choice for many individuals with CAD. Since PCI is not a cure, secondary prevention strategies are critical to prevent disease progression. Unfortunately, current strategies ignore the specific needs of the elective PCI population. In this article, the authors highlight the unique characteristics of these patients, which may contribute to their lack of engagement in healthy lifestyles. Elective PCI patients are vulnerable due to limited knowledge and follow-up, and lack of enrolment in secondary prevention programs. Exercise is a central component of any cardiac prevention strategy. Individualized exercise programs that incorporate physical activity and counselling can potentially improve the clinical outcomes of these patients. Advanced practice cardiovascular nurses play a key role in developing, implementing, and evaluating exercise programs in this population.
