Caregivers’ contributions to heart failure self-care: A systematic review:

Aims: The purpose of this study was to conduct a systematic review answering the following questions: (a) what specific activities do caregivers (CGs) contribute to patients’ self-care in heart failure (HF)?; and (b) how mature (or developed) is the science of the CG contribution to self-care? Methods: MEDLINE, EMBASE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), the Cochrane Library and ClinicalTrials.gov were searched using the terms heart failure and caregiv* as well as the keywords ‘careers’, ‘family members’ and ‘lay persons’ for studies published between 1948 and September 2012. Inclusion criteria for studies were: informal CGs of adult HF patients–either as dependent/independent variable in quantitative studies or participant in qualitative studies; English language. Exclusion criteria for studies were: formal CGs; pediatric, adult congenital, or devices or transplant CGs; mixed diagnosis; non-empiric reports or reports publishing duplicate results. Each study was abstracted and confirmed by two authors. After CG activities were identified and theoretically categorized, an analysis across studies was conducted. Results: Forty papers were reviewed from a pool of 283 papers. CGs contribute substantively to HF patients’ self-care characterized from concrete (weighing the patient) to interpersonal (providing understanding). Only two studies attempted to quantify the impact of CGs’ activities on patients’ self-care reporting a positive impact. Our analysis provides evidence for a rapidly developing science that is based largely on observational research. Conclusions and implications of key findings: To our knowledge, this is the first systematic review to examine CGs’ contributions in depth. Informal caregivers play a major role in HF self-care. Longitudinal research is needed to examine the impact of CGs’ contributions on patient self-care outcomes.

Presentation, Diagnosis, and Medical Management of Heart Failure in Children: Canadian Cardiovascular Society Guidelines

Pediatric heart failure (HF) is an important cause of morbidity and mortality in childhood. This article presents guidelines for the recognition, diagnosis, and early medical management of HF in infancy, childhood, and adolescence. The guidelines are intended to assist practitioners in office-based or emergency room practice, who encounter children with undiagnosed heart disease and symptoms of possible HF, rather than those who have already received surgical palliation. The guidelines have been developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, and are accompanied by practical Recommendations for their application in the clinical setting, supplemented by online material. This work does not include Recommendations for advanced management involving ventricular assist devices, or other device therapies.

An Interfaculty Pain Curriculum: Lessons learned from six years experience

Abstract Minimal pain content has been documented in pre‐licensure curricula and students lack important pain knowledge at graduation. To address this problem, we have implemented and evaluated a mandatory Interfaculty Pain Curriculum (IPC) yearly since 2002 for students (N = 817 in 2007) from six Health Science Faculties/Departments. The 20‐h pain curriculum continues to involve students from Dentistry, Medicine, Nursing, Pharmacy, Physical Therapy, and Occupational Therapy as part of their 2nd or 3rd year program. Evaluation methods based on Kirkpatrick’s model now include evaluation of a Comprehensive Pain Management Plan along with the previously used Pain Knowledge and Beliefs Questionnaire (PKPQ) and Daily Content and Process Questionnaires (DCPQ). Important lessons have been learned and subsequent changes made in this iterative curriculum design based on extensive evaluation over the 6‐year period. Modifications have included case development more relevant to the diverse student groups, learning contexts that are uni‐, inter‐, and multi‐professional, and facilitator development in working with interprofessional student groups. PKBQ scores have improved in all years with a statistically significant average change on correct responses from 14% to 17%. The DCPQ responses have also indicated consistently that most students (85–95%) rated highly the patient panel, expert‐lead clinically focused sessions, and small interprofessional groups. Relevancy and organization of the information presented have been generally rated highly from 80.3% to 91.2%. This curriculum continues to be a unique and valuable learning opportunity as we utilize lessons learned from extensive evaluation to move the pain agenda forward with pre‐licensure health science students.

Randomized controlled trial of a psychoeducation program for the self-management of chronic cardiac pain.

Cardiac pain arising from chronic stable angina (CSA) is a cardinal symptom of coronary artery disease and has a major negative impact on health-related quality of life (HRQL), including pain, poor general health status, and inability to self-manage. Current secondary prevention approaches lack adequate scope to address CSA as a multidimensional ischemic and persistent pain problem. This trial evaluated the impact of a low-cost six-week angina psychoeducation program, entitled The Chronic Angina Self-Management Program (CASMP), on HRQL, self-efficacy, and resourcefulness to self-manage anginal pain. One hundred thirty participants were randomized to the CASMP or three-month wait-list usual care; 117 completed the study. Measures were taken at baseline and three months. General HRQL was measured using the Medical Outcomes Study 36-Item Short Form and the disease-specific Seattle Angina Questionnaire (SAQ). Self-efficacy and resourcefulness were measured using the Self-Efficacy Scale and the Self-Control Schedule, respectively. The mean age of participants was 68 years, 80% were male. Analysis of variance of change scores yielded significant improvements in treatment group physical functioning [F=11.75(1,114), P<0.001] and general health [F=10.94(1,114), P=0.001] aspects of generic HRQL. Angina frequency [F=5.57(1,115), P=0.02], angina stability [F=7.37(1,115), P=0.001], and self-efficacy to manage disease [F=8.45(1,115), P=0.004] were also significantly improved at three months. The CASMP did not impact resourcefulness. These data indicate that the CASMP was effective for improving physical functioning, general health, anginal pain symptoms, and self-efficacy to manage pain at three months and provide a basis for long-term evaluation of the program.

Association of Postoperative High-Sensitivity Troponin Levels With Myocardial Injury and 30-Day Mortality Among Patients Undergoing Noncardiac Surgery

Importance Little is known about the relationship between perioperative high-sensitivity troponin T (hsTnT) measurements and 30-day mortality and myocardial injury after noncardiac surgery (MINS). Objective To determine the association between perioperative hsTnT measurements and 30-day mortality and potential diagnostic criteria for MINS (ie, myocardial injury due to ischemia associated with 30-day mortality). Design, Setting, and Participants Prospective cohort study of patients aged 45 years or older who underwent inpatient noncardiac surgery and had a postoperative hsTnT measurement. Starting in October 2008, participants were recruited at 23 centers in 13 countries; follow-up finished in December 2013. Exposures Patients had hsTnT measurements 6 to 12 hours after surgery and daily for 3 days; 40.4% had a preoperative hsTnT measurement. Main Outcomes and Measures A modified Mazumdar approach (an iterative process) was used to determine if there were hsTnT thresholds associated with risk of death and had an adjusted hazard ratio (HR) of 3.0 or higher and a risk of 30-day mortality of 3% or higher. To determine potential diagnostic criteria for MINS, regression analyses ascertained if postoperative hsTnT elevations required an ischemic feature (eg, ischemic symptom or electrocardiography finding) to be associated with 30-day mortality. Results Among 21 842 participants, the mean age was 63.1 (SD, 10.7) years and 49.1% were female. Death within 30 days after surgery occurred in 266 patients (1.2%; 95% CI, 1.1%-1.4%). Multivariable analysis demonstrated that compared with the reference group (peak hsTnT <5 ng/L), peak postoperative hsTnT levels of 20 to less than 65 ng/L, 65 to less than 1000 ng/L, and 1000 ng/L or higher had 30-day mortality rates of 3.0% (123/4049; 95% CI, 2.6%-3.6%), 9.1% (102/1118; 95% CI, 7.6%-11.0%), and 29.6% (16/54; 95% CI, 19.1%-42.8%), with corresponding adjusted HRs of 23.63 (95% CI, 10.32-54.09), 70.34 (95% CI, 30.60-161.71), and 227.01 (95% CI, 87.35-589.92), respectively. An absolute hsTnT change of 5 ng/L or higher was associated with an increased risk of 30-day mortality (adjusted HR, 4.69; 95% CI, 3.52-6.25). An elevated postoperative hsTnT (ie, 20 to <65 ng/L with an absolute change ≥5 ng/L or hsTnT ≥65 ng/L) without an ischemic feature was associated with 30-day mortality (adjusted HR, 3.20; 95% CI, 2.37-4.32). Among the 3904 patients (17.9%; 95% CI, 17.4%-18.4%) with MINS, 3633 (93.1%; 95% CI, 92.2%-93.8%) did not experience an ischemic symptom. Conclusions and Relevance Among patients undergoing noncardiac surgery, peak postoperative hsTnT during the first 3 days after surgery was significantly associated with 30-day mortality. Elevated postoperative hsTnT without an ischemic feature was also associated with 30-day mortality.

Management of Patients With Refractory Angina: Canadian Cardiovascular Society/Canadian Pain Society Joint Guidelines

Refractory angina (RFA) is a debilitating disease characterized by cardiac pain resistant to conventional treatments for coronary artery disease including nitrates, calcium-channel and β-adrenoceptor blockade, vasculoprotective agents, percutaneous coronary interventions, and coronary artery bypass grafting. The mortality rate of patients living with RFA is not known but is thought to be in the range of approximately 3%. These individuals suffer severely impaired health-related quality of life with recurrent and sustained pain, poor general health status, psychological distress, impaired role functioning, and activity restriction. Effective care for RFA sufferers in Canada is critically underdeveloped. These guidelines are predicated upon a 2009 Canadian Cardiovascular Society (CCS) Position Statement which identified that underlying the problem of RFA management is the lack of a formalized, coordinated, interprofessional strategy between the cardiovascular and pain science/clinical communities. The guidelines are therefore a joint initiative of the CCS and the Canadian Pain Society (CPS) and make practice recommendations about treatment options for RFA that are based on the best available evidence. Concluding summary recommendations are also made, giving direction to future clinical practice and research on RFA management in Canada.

Critical Care Nurses’ Pain Assessment and Management Practices: A Survey in Canada

BACKGROUND Regular pain assessment can lead to decreased incidence of pain and shorter durations of mechanical ventilation and stays in the intensive care unit. OBJECTIVES To document knowledge and perceptions of pain assessment and management practices among Canadian intensive care unit nurses. METHODS A self-administered questionnaire was mailed to 3753 intensive care unit nurses identified through the 12 Canadian provincial/territorial nursing associations responsible for professional regulation. RESULTS A total of 842 nurses (24%) responded, and 802 surveys could be evaluated. Nurses were significantly less likely (P < .001) to use a pain assessment tool for patients unable to communicate (267 nurses, 33%) than for patients able to self-report (712 nurses, 89%). Significantly fewer respondents (P < .001) rated behavioral pain assessment tools as moderately to extremely important (595 nurses, 74%) compared with self-report tools (703 nurses, 88%). Routine (>50% of the time) discussion of pain scores during nursing handover was reported by 492 nurses (61%), and targeting of analgesia to a pain score or other assessment parameters by physicians by 333 nurses (42%). Few nurses (n = 235; 29%) were aware of professional society guidelines for pain assessment and management. Routine use of a behavioral pain tool was associated with awareness of published guidelines (odds ratio, 2.5; 95% CI, 1.7-3.7) and clinical availability of the tool (odds ratio, 2.6; 95% CI, 1.6-4.3). CONCLUSIONS A substantial proportion of intensive care unit nurses did not use pain assessment tools for patients unable to communicate and were unaware of pain management guidelines published by professional societies.

Cost of illness for chronic stable angina patients enrolled in a self-management education trial

BACKGROUND Chronic stable angina (CSA) is a major debilitating health problem in Canada. A paucity of relevant cardiovascular data sets has precluded a detailed examination of the impact of interventions on CSA-related costs and its broader economic burden. OBJECTIVES As part of a larger clinical trial, the authors sought to determine the short-term impact of a standardized self-management training program on CSA-related costs. A secondary objective was to estimate the total annualized cost of CSA per patient from a societal perspective. METHODS Pre- and three-month post-test cost data were collected on 117 participants using the Ambulatory Home Care Record. Mean annualized direct, indirect and system-related CSA costs (2003 to 2005) were estimated; total per-patient CSA costs from a societal perspective were calculated as the sum of these costs. RESULTS The mean (+/- SD) age of participants was 68+/-11 years; 80% were male. The program did not impact costs in the short-term. Direct annual out-of-pocket costs, including money paid for health care, travel to appointments, medication, equipment and home support totaled
