Optimizing care of patients undergoing cardiac surgery using a digital platform and a multidisciplinary team approach.

OBJECTIVE: Restrictions to care access during the pandemic along with the increasing complexity of patients awaiting cardiac surgery provides unique challenges for care delivery. The University of Ottawa Heart Institute has developed a novel multidisciplinary digital platform, the Prehab Automated Follow-Up (AFU) Program, which delivers patient/caregiver teaching regarding risk factor mitigation, tracks patient symptoms, and screens for optimization using best practice guidelines. This study was conducted to quantify patient outcomes following initiation of the AFU Program. METHODS: Patients awaiting elective cardiac surgery are enrolled and screened via automated telephone conversation, according to best practice guidelines, and a Short Form-12 preoperative assessment. Following this screen, patients are referred for an in-person assessment by an appropriate multidisciplinary team member; namely, a diabetes specialist, physiotherapist, dietitian, smoking cessation counselor, social worker, vocational counselor, and/or psychologist. RESULTS: Since initiation in February 2021, the AFU Program has enrolled more than 1237 patients with 508 multidisciplinary team referrals prompted by the AFU screening platform. Before program initiation, there were no multidisciplinary team referrals for preoperative optimization. Compared with patients treated between February 2020 and February 2021, there was a 2.5% decrease in hospital readmission rate within 30 days of surgery, a 0.6-day shorter hospital stay, and a 2.5% decrease in surgical site infection. CONCLUSIONS: Our cardiac surgery AFU Program reduced adverse health outcomes for patients by identifying and optimizing risk factors that increased quality of patient care. The AFU Program provides patient/caregiver engagement through educational support and multidisciplinary team counseling.

Caregiver Distress and Coronary Artery Disease: Prevalence, Risk, Outcomes, and Management.

PURPOSE OF REVIEW: Caregivers of patients with coronary artery disease (CAD) are integral to the health care system and contribute substantially to patients' management. The purpose of this review is to provide a narrative synthesis of existing research on caregiving for patients who experienced an acute coronary syndrome (MI/unstable angina) and/or coronary revascularization (PCI/CABG). RECENT FINDINGS: Thirty-one articles are included in this review. Overall, caregiver distress is low to moderate, ranging from 6 to 67% of caregivers, and seems to dissipate over time for most caregivers. Interventions have demonstrated success in reducing the distress of caregivers of patients with CAD. Due to the heterogeneity in study samples, measurements used, and timing of assessments and programming, these results are far from definitive. Although evidence is accumulating, further advancement in caregiving science and clinical care is required to adequately understand and respond to the needs of caregivers throughout the patient's illness trajectory.

Cognitive dysfunction after out-of-hospital cardiac arrest: Rate of impairment and clinical predictors.

BACKGROUND: The purpose of this study was to evaluate the rate and domains of cognitive impairment in out-of-hospital cardiac arrest (OHCA) survivors, as compared to patients who experienced a myocardial infarction (MI), and to explore mechanisms and predictors of this impairment. METHODS AND RESULTS: OHCA survivors with "good" neurological recovery (i.e., Cerebral Performance Categories Scale ≤ 2) (n = 79), as well as a control group of MI patients (n = 69), underwent a comprehensive neuropsychological assessment. Forty-three percent of OHCA survivors were cognitively impaired (in the lowest decile on a global measure of cognitive functioning). Rates of impairment were approximately six times higher in the OHCA group than the MI group. Attention, memory, language and executive function were affected. Downtime was a significant predictor of cognitive impairment; the interaction between downtime and immediate intervention was significant such that, at short downtimes, receiving cardiopulmonary resuscitation (CPR) or defibrillation within 1 min of collapse predicted less cognitive impairment. CONCLUSIONS: OHCA survivors - even those with seemingly good neurological recovery - are at risk for cognitive impairment. Cognitive rehabilitation may be an important consideration post-OHCA.

Exploratory Analyses of Cerebral Gray Matter Volumes After Out-of-Hospital Cardiac Arrest in Good Outcome Survivors.

BACKGROUND: Survival rates of cardiac arrest have increased over recent years, however, survivors may still be left with significant morbidity and functional impairment. A primary concern in cardiac arrest survivors is the effect of prolonged hypoxia/ischemia on the brain. The objectives of the present study were threefold: (1) to explore the effect of cardiac arrest on brain gray matter volumes (GMV) in "good outcome" survivors of out-of-hospital cardiac arrest (OHCA), (2) to examine the relationship between GMV, cognitive functioning and arrest factors, and (3) to explore whether OHCA patients differ from a group of patients with myocardial infarction (MI) uncomplicated by cardiac arrest and a group of healthy controls in terms of GMV. METHODS: Medically stable OHCA survivors with preserved neurological function and who were eligible for magnetic resonance imaging scanning (MRI; n = 9), were compared to: (1) patients who had experienced a MI (n = 19) and (2) healthy controls (n = 12). Participants underwent brain MRI on a 3T Siemens Trio MRI scanner and GMV was measured by voxel-based morphometry. A comprehensive neuropsychological assessment was also conducted. Global GMV was compared in the three samples using analyses of variance. The relationships between cognition and GMV were examined within group using correlations. RESULTS: The OHCA and MI groups showed a similar pattern of differences compared to the healthy control group. Both groups had decreased GMV in the anterior cingulate cortex, bilateral hippocampus, right dorsolateral prefrontal cortex, right putamen, and bilateral cerebellum. There were no significant differences in global or regional GMV between the OHCA and MI groups. Cognitive functioning was correlated with global GMV in the OHCA group; no such correlation was observed in the MI group. CONCLUSION: Regional atrophy was observed in OHCA and MI survivors, compared to a healthy control group, suggesting a common mechanism, presumably preexisting cardiovascular disease. Although similar regional volume differences were observed between the MI and OHCA groups, the relationship between GMV and cognition was only observed in OHCA survivors. We suggest the acute hypoxia/ischemia ensuing from the arrest may interact with diminished neural reserve in select brain areas to expose occult cognitive dysfunction.

Supporting the Health and Well-being of Caregivers: Co-design in Practice at a Canadian Cardiac Care Center.

BACKGROUND: Caregivers contribute substantially to patients' management of and recovery from cardiovascular disease (CVD). Yet, the distress that many caregivers experience in this role continues to be underresearched and their needs undersupported. PURPOSE: Situated within a patient engagement framework and adapted from experience-based co-design guidelines, the process of developing a comprehensive caregiver support resource with joint contributions from caregivers and healthcare providers representing multiple disciplines is described. A discussion of the challenges encountered during the development of the caregiver support resource and recommendations for future sites embarking on co-design work are noted. CONCLUSION: Developing feasible and relevant approaches, such as informational support instruments, to meet the needs of the growing population of CVD caregivers is essential. CLINICAL IMPLICATIONS: Although co-design processes are often complex, take more time and resources to implement, and involve multiple levels of an organization and community than traditional practices, these efforts may help to improve healthcare quality to stem the burden of CVD.

Transitional care post TAVI: A pilot initiative focused on bridging gaps and improving outcomes.

Interventions focused on ensuring safe transitions for patients from hospital to home can assist in providing continuity of care, preventing readmissions, and reducing duplication of services. Patients undergoing a Transcatheter Aortic Valve Implantation (TAVI) procedure are often frail, elderly, and have multiple co-morbidities. A pilot initiative evaluating transitional care strategies through telephone follow up was implemented in a tertiary centre with the aim to identify gaps and intervene, preventing re-admission and improving patient outcomes. TAVI patients or caregivers were contacted at 3 days and 30 days post discharge by an Advanced Practice Nurse (APN). Telephone follow up centered on best practices for transitional care. Outcomes revealed fluid balance monitoring, medication management, and feelings of anxiety and depression post TAVI were the most frequent areas requiring intervention. Findings from this initiative reinforce the need to establish consistent processes that support elderly patient populations during potentially vulnerable points in the care trajectory.

A Multidisciplinary Approach to the Development and Implementation of Best Practices Usng an Innovative Clinical Pathway for the Management of Cardiac Arrest Patients with Cognitive Dysfunction: A Case Study.

Out-of-hospital cardiac arrest (OOHCA) affects 20 to 140 people per 100,000 globally with survival rangingfrom 2% to 11% (Meaney et al., 2013). Patients who have survived, but have been left with cognitive impairments due to anoxic brain injury should be offered early identification and initiation of rehabilitation needs during their admission to mitigate the impact of these deficits (Moulaert et al., 2011). Unfortunately, most cardiac survivors do not receive specialized rehabilitation during their acute hospitalization and there are no clinical pathways that currently exist to guide acute care practitioners regarding the appropriate timing of cognitive screens and early rehabilitation interventions. This tertiary care institution designed and implemented a clinical pathway and patient and family education tools, which have systematically improved the identification and treatment ofpatients requiring cognitive rehabilitation. In this paper, the authors discuss the pathway/tool development and use a case study to highlight these interventions.

Smoking cessation: lessons learned from clinical trial evidence.

PURPOSE OF REVIEW: Cigarette smoking and exposure to secondhand smoke cause coronary heart disease. Cessation dramatically reduces the incidence of primary and secondary cardiac events. The review presents up-to-date information regarding nicotine dependence, recent findings related to its treatment, and recommendations for addressing smoking cessation for the primary and secondary prevention of coronary heart disease. RECENT FINDINGS: Bans on smoking in public places are associated with significant reductions in the incidence of acute myocardial infarction. Counseling and pharmacotherapy (nicotine replacement therapy, bupropion) are proven, effective treatments for nicotine dependence. Clinical trials of two new pharmacotherapies, varenicline and rimonabant, have recently been reported. Varenicline is a safe and efficacious medication for smoking cessation, and has been approved in the US, Canada and Europe. Rimonabant has shown mixed results for smoking cessation and is undergoing further evaluation. SUMMARY: All patients should be screened for tobacco use. Clinicians can effectively treat nicotine dependence in the general population using counseling and first-line pharmacotherapies (nicotine replacement therapy, bupropion, varenicline). These same treatments, with some modification, are appropriate for smokers with coronary heart disease; however, brief interventions without follow-up are not effective in this population. For smokers with coronary heart disease, the best time to intervene may be during hospitalization.

Interactive voice response telephony to promote smoking cessation in patients with heart disease: a pilot study.

OBJECTIVE: A pilot study was conducted to determine the feasibility and potential efficacy of an interactive voice response (IVR) follow-up system for smokers recently hospitalized with coronary heart disease (CHD). METHODS: Ninety-nine smokers hospitalized with CHD completed a baseline questionnaire, were provided with bedside counseling, and offered nicotine replacement therapy. They were randomly assigned to a usual care (UC) or an IVR group. The IVR group received automated telephone follow-up calls 3, 14 and 30 days after discharge inquiring about their smoking status and confidence in remaining smoke-free. When deemed necessary, they were offered additional counseling. Smoking status was determined 52 weeks after hospital discharge. RESULTS: The 52-week point prevalence abstinence rate in the IVR group was 46.0% compared to 34.7% in the UC group (OR=1.60, 95% CI: 0.71-3.60; P=.25). After adjustment for education, age, reason for hospitalization, length of hospitalization, and quit attempts in the past year, the odds of quitting in the IVR group compared to the UC group were 2.34 (95% CI: 0.92-5.92; P=.07). CONCLUSIONS: IVR is a promising technology for following CHD patients attempting to quit smoking following discharge from hospital, however, a larger trial is required to confirm its efficacy. PRACTICE IMPLICATIONS: IVR may enhance the timely provision of follow-up counseling for smoking cessation in patients with CHD.

Promoting smoking cessation during hospitalization for coronary artery disease.

BACKGROUND: Quitting smoking is the most effective intervention to reduce mortality in patients with coronary artery disease who smoke. Guidelines for the treatment of tobacco dependency recommend that health care institutions develop plans to support the consistent and effective identification and treatment of tobacco users. The University of Ottawa Heart Institute (Ottawa, Ontario) has implemented an institutional program to identify and treat all smokers admitted to the Institute. OBJECTIVES: The objectives of the present paper are to describe core elements of this program and present data concerning its reach and effectiveness. PROGRAM DESCRIPTION: The goal of the program is to increase the number of smokers who are abstinent from smoking six months after a coronary artery disease-related hospitalization. Core elements of the program include: documentation of smoking status at hospital admission; inclusion of cessation intervention on patient care maps; individualized, bedside counselling by a nurse counsellor; the appropriate and timely use of nicotine replacement therapy; automated telephone follow-up; referral to outpatient cessation resources; and training of medical residents and nursing staff. Program reach and effectiveness were measured over a one-year period. RESULTS: Between April 2003 and March 2004, almost 1300 smokers were identified at admission, and 91% received intervention to help them quit smoking. At six-month follow-up, 44% were smoke-free. CONCLUSIONS: Hospitalization for coronary artery disease provides an important opportunity to intervene with smokers when their motivation to quit is high. An institutional approach reinforces the importance of smoking cessation in this patient population and increases the rate of smoking cessation. Posthospitalization quit rates should be a benchmark of cardiac program performance.

Restrictive visitor policies: feedback from healthcare workers, patients and families.

With the hospital-based transmission of Severe Acute Respiratory Syndrome (SARS) in Ontario, acute care hospitals severely restricted visitor access. Now that the SARS outbreak is under control, hospitals struggle with the balance between adhering to patient- and family-centred care models, and addressing the future threat of infectious diseases. To evaluate the effect of visitor restrictions and to guide future visitation policies, the Ottawa Hospital conducted a preliminary survey of patients, next of kin, staff, physicians and volunteers. Ninety percent of staff surveyed supported some form of visitor restrictions, while 71% indicated that they felt comfortable asking visitors to leave if they had exceeded current restrictions. The majority of patients (80%) and next of kin (76%) were at least moderately satisfied with current restricted limiting hours. A disproportionate number of positive comments on current visiting restrictions were received from both patients and staff. In the absence of evidence on which to base future visitor policy development, objective input from healthcare workers, patients and families is invaluable.
