Clinical Effectiveness and Utilisation of Cardiac Rehabilitation After Hospital Discharge: Data Linkage Analysis of 84,064 Eligible Discharged Patients (2016-2021).

BACKGROUND: Despite the highest levels of evidence on cardiac rehabilitation (CR) effectiveness, its translation into practice is compromised by low participation. AIM: This study aimed to investigate CR utilisation and effectiveness in South Australia. METHODS: This retrospective cohort study used data linkage of clinical and administrative databases from 2016 to 2021 to assess the association between CR utilisation (no CR received, commenced without completing, or completed) and the composite primary outcome (mortality/cardiovascular re-admissions within 12 months after discharge). Cox survival models were adjusted for sociodemographic and clinical data and applied to a population balanced by inverse probability weighting. Associations with non-completion were assessed by logistic regression. RESULTS: Among 84,064 eligible participants, 74,189 did not receive CR, with 26,833 of the 84,064 (31.9%) participants referred. Of these, 9,875 (36.8%) commenced CR, and 7,681 of the 9,875 (77.8%) completed CR. Median waiting time from discharge to commencement was 40 days (interquartile range, 23-79 days). Female sex (odds ratio [OR] 1.12; 95% CI 1.01-1.24; p=0.024), depression (OR 1.17; 95% CI 1.05-1.30; p=0.002), and waiting time >28 days (OR 1.15; 95% CI 1.05-1.26; p=0.005) were associated with higher odds of non-completion, whereas enrolment in a telehealth program (OR 0.35; 95% CI 0.31-0.40; p<0.001) was associated with lower odds of non-completion. Completing CR (hazard ratio [HR] 0.62; 95% CI 0.58-0.66; p<0.001) was associated with a lower risk of 12-month mortality/cardiovascular re-admissions. Commencing without completing was also associated with decreased risk (HR 0.81; 95% CI 0.73-0.90; p<0.001), but the effect was lower than for those completing CR (p<0.001). CONCLUSIONS: Cardiac rehabilitation (CR) attendance is associated with lower all-cause mortality/cardiovascular re-admissions, with CR completion leading to additional benefits. Quality improvement initiatives should include promoting referral, women's participation, access to telehealth, and reduction of waiting times to increase completion.

Randomized controlled trial of perhexiline on regression of left ventricular hypertrophy in patients with symptomatic hypertrophic cardiomyopathy (RESOLVE-HCM trial).

BACKGROUND: The presence and extent of left ventricular hypertrophy (LVH) is a major determinant of symptoms in patients with hypertrophic cardiomyopathy (HCM). There is increasing evidence to suggest that myocardial energetic impairment represents a central mechanism leading to LVH in HCM. There is currently a significant unmet need for disease-modifying therapy that regresses LVH in HCM patients. Perhexiline, a potent carnitine palmitoyl transferase-1 (CPT-1) inhibitor, improves myocardial energetics in HCM, and has the potential to reduce LVH in HCM. OBJECTIVE: The primary objective is to evaluate the effects of perhexiline treatment on the extent of LVH, in symptomatic HCM patients with at least moderate LVH. METHODS/DESIGN: RESOLVE-HCM is a prospective, multicenter double-blind placebo-controlled randomized trial enrolling symptomatic HCM patients with at least moderate LVH. Sixty patients will be randomized to receive either perhexiline or matching placebo. The primary endpoint is change in LVH, assessed utilizing cardiovascular magnetic resonance (CMR) imaging, after 12-months treatment with perhexiline. SUMMARY: RESOLVE-HCM will provide novel information on the utility of perhexiline in regression of LVH in symptomatic HCM patients. A positive result would lead to the design of a Phase 3 clinical trial addressing long-term effects of perhexiline on risk of heart failure and mortality in HCM patients.

Outcomes of observation as therapy for pelvic organ prolapse: a study in the natural history of pelvic organ prolapse.

AIMS: To determine the rate of progression or regression of pelvic organ prolapse (POP) in subjects with symptomatic POP who decline intervention (pessary or surgery) and elect observation. METHODS: Sixty-four patients choosing observation as primary management of symptomatic POP were followed with sequential pelvic organ prolapse quantification (POP-Q) exams. A change in the leading edge value of ±≥2 cm was considered significant. POP-Q exam results, choice of therapy and symptom severity at last visit were recorded. RESULTS: The leading vaginal edge POP-Q exam value at initial exam ranged from -1.5 to 7 cm. Distribution of patients by POP-Q stages on initial exam was: stage I: 1%, stage II: 31%, stage III: 31%, and stage IV: 1.78% (50/64) of patients demonstrated no change in leading edge value from first to last visit on POP-Q exams. Nineteen percent (12/64) demonstrated progression (≥2 cm increase in leading edge); 3% (2/64) demonstrated regression (≥2 cm decrease in leading edge). Median follow-up was 16 months (range 6-91 months). On multivariate analysis, no variable, including length of follow-up, was associated with change in leading edge value (P = 0.09, data not shown). At their last recorded visit, 63% (40/64) of subjects continued observation, 38% (24/64) desired a pessary trial or surgical correction. Those desiring intervention had no greater worsening of prolapse on exam at last follow-up compared with subjects who continued observation. CONCLUSION: The natural history of pelvic organ prolapse is most often one of very minimal change in subjects who decline intervention (pessary or surgery) and choose observation.

Effectiveness of discharge education strategies versus usual care on clinical outcomes in acute coronary syndrome patients: a systematic review.

OBJECTIVE: The objective of this review was to systematically review studies that evaluated the clinical effectiveness of hospital discharge education strategies provided to patients with acute coronary syndrome (ACS). INTRODUCTION: In an era of shortening lengths of stay for patients with ACS, bedside education opportunities are diminishing; however, the importance of discharge education on medication management, emergency procedures and safe recovery remains vital to prevent rehospitalization. INCLUSION CRITERIA: The following studies were considered for inclusion: English-language randomized controlled trials (RCTs) measuring educational strategies provided to adults with ACS as the only intervention prior to discharge or post-discharge from acute care, compared to usual care. METHODS: An electronic search was performed by an experienced research librarian. MEDLINE, CINAHL, PsycINFO, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, Australian New Zealand Clinical Trials Registry, ClinicalTrials.gov and WHO International Clinical Trial Registry Platform were searched for studies published between 2000 and 2017. All citations were collated and uploaded into EndNote where duplicates were removed. Titles and abstracts were screened by two independent reviewers. The reference lists of all included studies were screened for additional references. Risk of bias was assessed using the JBI critical appraisal instrument for all included studies. In the case of missing or incomplete data, corresponding authors were contacted. The primary outcomes of interest were knowledge relating to ACS diagnosis, treatment and procedures. Secondary outcomes included lifestyle modifications, medication adherence/knowledge, general practitioner follow-up, attendance to cardiac rehabilitation (CR), readmission and mortality (up to 12 months). As data were collected using different instruments in each study, meta-analysis was not performed. RESULTS: The electronic search identified 3445 records. Following deduplication, 2093 citations were screened with 47 papers selected for assessment of eligibility. Three RCTs involving 175 participants were identified for inclusion. The certainty of this evidence (Grading of Recommendations, Assessment, Development and Evaluation) was rated as low to moderate. The risk of bias for all included studies was moderate. In all studies, the impact of inpatient educational interventions was assessed in relation to attendance to a CR program, exercise rates and medication adherence. Interventions included targeted educational sessions (15-40 minutes) where participants prioritized their learning needs and were provided tailored cardioprotective risk factor and lifestyle modification advice and invited to attend a CR program. One study presented the education in animation. In one study, intervention groups reported increased attendance to CR compared to control (47.3%; n = 9, versus 21.1%; n = 4) and another demonstrated significantly increased exercise rates from baseline to follow-up. No significant difference was reported between the intervention and control for medication adherence, and none of the studies reported readmission or mortality rates. CONCLUSION: The current review found little to no evidence for the effectiveness of current discharge practices on clinical outcomes. There has been limited research on modes of delivery or what the essential components for ACS discharge education should be. This review has highlighted the need for comprehensive effectiveness studies to provide a strong evidence-base to support ACS discharge practices.

Examining adherence to activity monitoring devices to improve physical activity in adults with cardiovascular disease: A systematic review.

BACKGROUND: Activity monitoring devices are currently being used to facilitate and monitor physical activity. No prior review has examined adherence to the use of activity monitoring devices amongst adults with cardiovascular disease. METHODS: Literature from June 2012 to October 2017 was evaluated to examine the extent of adherence to any activity monitoring device used to collect objective physical activity data. Randomized control trials comparing usual care against the use of an activity monitoring device, in a community intervention for adults from any cardiovascular diagnostic group, were included. A systematic search of databases and clinical trials registers was conducted using Joanna Briggs Institute methodology. RESULTS: Of 10 eligible studies, two studies reported pedometer use and eight accelerometer use. Six studies addressed the primary outcome. Mean adherence was 59.1% (range 39.6% to 85.7%) at last follow-up. Studies lacked equal representation by gender (28.6% female) and age (range 42 to 82 years). CONCLUSION: This review indicates that current research on activity monitoring devices may be overstated due to the variability in adherence. Results showed that physical activity tracking in women and in young adults have been understudied.

The Keeping on Track Study: Exploring the Activity Levels and Utilization of Healthcare Services of Acute Coronary Syndrome (ACS) Patients in the First 30-Days after Discharge from Hospital.

The aim of this study was to investigate the impact of bedside discharge education on activity levels and healthcare utilization for patients with acute coronary syndrome (ACS) in the first 30 days post-discharge. Knowledge recall and objective activity and location data were collected by global positioning systems (GPS). Participants were asked to carry the tracking applications (apps) for 30⁻90 days. Eighteen participants were recruited (6 metropolitan 12 rural) 61% ST elevation myocardial infarction (STEMI), mean age 55 years, 83% male. Recall of discharge education included knowledge of diagnosis (recall = 100%), procedures (e.g., angiogram = 40%), and comorbidities (e.g., hypertension = 60%, diabetes = 100%). In the first 30 days post-discharge, median steps per day was 2506 (standard deviation (SD) ± 369) steps (one participant completed 10,000 steps), 62% visited a general practitioner (GP) 16% attended cardiac rehabilitation, 16% visited a cardiologist, 72% a pharmacist, 27% visited the emergency department for cardiac event, and 61% a pathology service (blood tests). Adherence to using the activity tracking apps was 87%. Managing Big Data from the GPS and physical activity tracking apps was a challenge with over 300,000 lines of raw data cleaned to 90,000 data points for analysis. This study was an example of the application of objective data from the real world to help understand post-ACS discharge patient activity. Rates of access to services in the first 30 days continue to be of concern.

Cardiotoxicity and cardiovascular disease risk assessment for patients receiving breast cancer treatment.

BACKGROUND: Cardiotoxicity from anticancer therapy affects heart function and structure. Cardiotoxicity can also lead to accelerated development of chronic diseases, especially in the presence of risk factors. METHODS: This study aimed to develop and pilot a combined cardiovascular disease and cardiotoxicity risk assessment questionnaire to quantify the potential extent of risk factors in breast cancer patients prior to treatment. The questionnaire underwent content and face validity evaluation by an expert panel followed by pilot testing in a sample of breast cancer patients (n = 36). Questionnaires were self-administered while attending chemotherapy clinic, in the presence of a research assistant. RESULTS: Mean age of participants was 54.8 years (range 36-72 years). Participants reported CVD risk factors including diabetes 2.8%, hypertension 19.8%, hypercholesterolaemia 11% and sleep apnoea 5%. Lifestyle risk factors, included not eating the recommended serves of vegetables (100%) or fruit (78%) per day; smoking (13%) and regularly consuming alcohol (75%). Twenty five percent reported being physically inactive, 61%, overweight or obese, 24%, little or no social support and 30% recorded high to very high psychological distress. Participants were highly (75%) reluctant to undertake lifestyle changes; i.e. changing alcohol consumption; dietary habits; good emotional/mental health strategies; improving physical activity; quitting smoking; learning about heart-health and weight loss. CONCLUSION: This study is an important step towards prevention and management of treatment-associated cardiotoxicity after breast cancer diagnosis. We recommend that our questionnaire is providing important data that should be included in cancer registries so that researchers can establish the relationship between CVD risk profile and cardiotoxicity outcomes and that this study revealed important teaching opportunities that could be used to examine the impact on health literacy and help patients better understand the consequences of cancer treatment.

Intensive care research coordinators: who are they and what do they do? Results of a binational survey.

Research coordinators in intensive care are a growing specialty about which little is known. This cross-sectional study surveyed the Australia and New Zealand Intensive Care Research Coordinators' Group (n = 49) regarding demographics, education, employment history, job structure, and role content. Most research coordinators were highly qualified and experienced nurses who undertake pharmaceutical trials, multicenter projects, departmental medical and nursing research, audits and data registries, and their own projects.

Job satisfaction and importance for intensive care unit research coordinators: results from binational survey.

OBJECTIVE: To measure Intensive Care Unit Research coordinator job satisfaction and importance and to identify priorities for role development. BACKGROUND: Research coordinator numbers are growing internationally in response to increasing clinical research activity. In Australia, 1% of registered nurses work principally in research, many as Research coordinators. Internationally, the Association of Clinical Research Professionals currently has 6536 certified Research coordinators in 13 countries, with likely additional large numbers practicing without the voluntary certification. Research coordinators are almost always nurses, but little is know about this emerging specialty. Design. Cross-sectional study using anonymous self-report questionnaire. METHODS: After ethics approval, the McCloskey-Mueller Satisfaction Scale and McCloskey-Mueller Importance Scale were administered via the Internet. The sample was 49 (response rate 71%) Research coordinators from the Australia and New Zealand Intensive Care Unit Research coordinators' Interest Group. RESULTS: Research coordinators were satisfied with structural aspects of the position working business hours; flexibility of working hours; high levels of responsibility and control over their work. Dissatisfaction was expressed regarding: remuneration and recognition; compensation for weekend work; salary package; career advancement opportunities; and childcare facilities. CONCLUSIONS: High priorities for role development are those rated highly important but with much lower satisfaction. These are: compensation for weekend call-out work; salary and remuneration package; recognition by management and clinicians; career advancement opportunities; departmental research processes; encouragement and feedback; and number of working hours. RELEVANCE TO CLINICAL PRACTICE: Increasing numbers of nurses have been attracted to this clinically based research position. These data contribute to the understanding and development of the role.

The best and worst aspects of the ICU research coordinator role.

BACKGROUND: The Research Coordinator (RC) role is a relative new addition to staffing profiles in Australasian Intensive Care Units (ICUs). The RC plays a pivotal role in conducting ethically and scientifically sound research. There have been anecdotal reports of the RC role in various speciality areas. However, limited research has been undertaken into the role, and only one study has been published from the intensive care setting. AIM: To evaluate which factors the RC found to be the best and worst attributes of the role. METHODS: A cross-sectional web-based cohort study was conducted in 2004 collecting free text information from RCs in ICUs in Australia and New Zealand. RESULTS: Forty-nine participants (71%) completed the study with 273 entries into the two categories of 'best' (60%) and 'worst' (40%) aspects of the role. We identified four thematic clusters in both categories: (1) 'How the job was structured' (2) 'The worth of the job' (3) 'What the work involves' and (4) 'Who I work with'. Both categories received proportionally the same number of responses in each theme with (1) the most frequent and (4) the least number of entries. CONCLUSION: There is much variation between RCs in almost every descriptor of the role. The Australasian Intensive Care RC values autonomy, respect and intellectual stimulation with the scope for extending the role to suit the individual and finds isolation, under-recognition and workload, often not sufficiently compensated, to be the worst aspects of the position.
