Barriers to Successful Discharge After Cardiac Surgery: A Focus Group Study and Cross-Sectional Survey.

At present, there is a lack of information on patient and caregiver values, and perceived priorities and barriers, to guide successful post-discharge recovery. This was a single center, multiple methods study that investigated patient, caregiver, and health care provider perceptions of the discharge process after cardiac surgery. Themes emerging from focus group discussions with patients and caregivers were used to develop surveys relating to values, barriers, and challenges relating to the discharge process. Thirty-two patients (n = 16) and caregivers (n = 16) participated in four separate focus groups. Four themes emerged from these discussions: (1) a lack of understanding about what the discharge process entails and when discharge is appropriate, (2) issues relating to the information provided to patients at the time of discharge, (3) participant experiences with the health care system, and (4) the experiences of caregivers. Seventy-eight patients, 34 caregivers, 53 nurses and/or other allied health professionals, and 8 surgeons completed the cross-sectional surveys. The most important component of the discharge process for patients and caregivers was "knowing what to do in an emergency." Health care providers less accurately identified what caregivers perceived as the most important aspects of the discharge process.Statements relating to informational barriers to discharge were the most discordant among patient and caregiver respondents. After discharge, patients and caregivers identified the need for longer-term follow up with the surgeon and more support in the community. Incorporation of patient and caregiver values to guide the post-cardiac surgery discharge process is essential to promote successful recovery.

Delirium definition influences prediction of functional survival in patients one-year postcardiac surgery.

BACKGROUND: Delirium after cardiac surgery is associated with prolonged intensive care unit (ICU) and hospital length of stay and elevated rates of mortality. The Society of Thoracic Surgery National Database (STS-ND) includes delirium in routine data collection but restricts its definition to hyperactive symptoms. The objective is to determine whether the Confusion Assessment Method for ICU (CAM-ICU), which includes hypo- and hyperactive symptoms, is associated with improved prediction of poor 1-year functional survival following cardiac surgery. METHODS: Clinical and administrative databases were used to determine the influence of postoperative delirium on 1-year poor functional survival, defined as being institutionalized or deceased at 1 year. Patients experiencing postoperative delirium using the STS-ND definition (2007-2009) were compared with patients with delirium identified by the CAM-ICU (2010-2012). A propensity score match was undertaken, and multivariable Cox proportional hazards regression models were generated to determine risk of poor 1-year functional survival. RESULTS: There were 2756 and 2236 patients in the STS-ND and CAM-ICU cohorts, respectively. Propensity matching resulted in a cohort of 1835 patients (82.1% matched). The overall rate of delirium in the matched study population was 7.6% in the STS-ND cohort and 13.0% in the CAM-ICU cohort (P < .001). Delirium in the CAM-ICU cohort was independently associated with poor 1-year functional survival (hazard ratio, 2.58; 95% confidence interval, 1.20-5.54; P = .02); delirium in the STS-ND cohort was not associated with poor 1-year functional survival (hazard ratio, 0.92; 95% confidence interval, 0.49-1.71; P = .79). CONCLUSIONS: A systematic screening tool identifies postoperative delirium with improved prediction of poor 1-year functional survival following cardiac surgery.

A Quality Improvement Initiative to Reduce Postoperative Delirium among Cardiac Surgery Patients.

Patients following cardiac surgery commonly experience post-operative delirium (POD) during their postoperative hospital stay. A multifaceted, specialty wide, quality improvement (QI) project was undertaken for patients experiencing POD. The goal was to develop a reduction in POD care bundle (rPOD-a structured patient care program) that encompasses efficient preoperative risk factor identification and a postoperative patient-care process to ensure early POD identification and treatment. The following steps were taken to implement the rPOD care bundle including: (a) Developing a quality driven, evidence-based guideline for the perioperative cardiac surgery health care team, (b) identifying and addressing local barriers to implementation, (c) selecting performance measures to assess intervention adherence and patient outcomes, and (d) ensuring that all patients receive the interventions through staff engagement and education, and regular project evaluation. Trends of process measures and quality improvement measures were examined. An increasing trend in the rate of postoperative delirium screening during implementation of rPOD intervention was demonstrated. This quality improvement study provides a bases for future postoperative delirium reduction interventions.

Impact of spironolactone exposure on prostate cancer incidence amongst men with heart failure: A Pharmacoepidemiological study.

AIMS: Aldosterone has been found to influence cancer cell growth, cell cycle regulation and cell migration, including in prostate cancer cells. Spironolactone is an aldosterone antagonist used for managing chronic heart failure (HF) with known antiandrogenic effects. We examined the effect of spironolactone exposure amongst men with HF on the incidence of prostate cancer. METHODS: This retrospective cohort study utilized provincial clinical and administrative databases from the Manitoba Centre for Health Policy. Incident cases of prostate cancer were identified from the provincial cancer registry, and spironolactone exposure was quantified from pharmacare databases. A multivariable proportional hazards model was used to assess the time-dependent impact of spironolactone exposure on prostate cancer incidence. RESULTS: A total of 18 562 men with newly diagnosed HF from 2007 to 2015 with a median age of 72 years (interquartile range: 61-81) and a median follow-up from HF diagnosis to prostate cancer incidence of 2.7 years (interquartile range: 1.1-4.9) were included. A time-dependent multivariable analysis of spironolactone exposure following HF diagnosis found a reduced the risk of prostate cancer hazard ratio 0.55 (95% confidence interval 0.31-0.98, P = .043). CONCLUSION: Spironolactone exposure significantly reduced the incidence of prostate cancer amongst men with HF. These findings support the plausibility of aldosterone as a promoter of prostate cancer growth and development. Prospective clinical trials are warranted to further assess the role of spironolactone or other mineralocorticoid receptor antagonists as a means to prevent prostate cancer development or as an adjunctive measure to prostate cancer treatments.

Comprehensive Geriatric Assessment in the Management of Older Patients With Cardiovascular Disease.

Cardiovascular disease (CVD) disproportionately affects older adults. It is expected that by 2030, one in five people in the United States will be older than 65 years. Individuals with CVD now live longer due, in part, to current prevention and treatment approaches. Addressing the needs of older individuals requires inclusion and assessment of frailty, multimorbidity, depression, quality of life, and cognition. Despite the conceptual relevance and prognostic importance of these factors, they are seldom formally evaluated in clinical practice. Further, although these constructs coexist with traditional cardiovascular risk factors, their exact prevalence and prognostic impact remain largely unknown. Development of the right decision tools, which include these variables, can facilitate patient-centered care for older adults. These gaps in knowledge hinder optimal care use and underscore the need to rigorously evaluate the optimal constructs for providing care to older adults. In this review, we describe available tools to examine the prognostic role of age-related factors in patients with CVD.

Dexmedetomidine versus propofol sedation in reducing delirium among older adults in the ICU: A systematic review and meta-analysis.

BACKGROUND: Delirium is common in the ICU, with incidence rates reported to be upwards of 70%. Due to the significant morbidity and mortality associated with delirium, it is hypothesised that a delirium-free sedative agent will improve outcomes in older adults admitted to the ICU. OBJECTIVES: To assess if dexmedetomidine sedation is associated with a reduction in ICU delirium among older adults, and to evaluate its risks and benefits compared with propofol sedation. DESIGN: Systematic review of randomised controlled trials and cohort studies with meta-analyses. DATA SOURCES: Articles published from database inception to 8 April 2019 were retrieved from Medline, EMBASE, Evidence-based Medicine Reviews, International Pharmaceutical Abstracts, Scopus, ClinicalTrials.gov and WHO Trials. ELIGIBILITY: Studies were included if they compared dexmedetomidine sedation with propofol in the ICU, reported the incidence of delirium as an outcome and had a mean/median sample age of at least 60. Studies that examined dexmedetomidine and propofol use intra-operatively or as part of general anaesthesia were excluded. RESULTS: Dexmedetomidine sedation was associated with a lower incidence of delirium when compared with propofol: seven studies, n=1249; risk ratio 0.70; 95% confidence interval (CI) 0.52 to 0.95; P = 0.02. There was no statistically significant difference in the incidence of bradycardia: three studies, n=278; risk ratio 1.52; 95% CI 0.85 to 2.72; P = 0.16, and hypotension: six studies, n=867 patients; risk ratio 1.12; 95% CI 0.86 to 1.45; P = 0.42. Dexmedetomidine sedation did not reduce hospital length of stay, ICU length of stay or duration of mechanical ventilation compared with propofol. CONCLUSION: Compared with propofol, dexmedetomidine sedation in the ICU is associated with lower delirium incidence among older adults with no significant increase in adverse events. In older adult ICU patients at risk of developing delirium, sedation with dexmedetomidine should be considered. Further research is warranted to elucidate and explain the mechanisms underlying this process, and to confirm our findings with large, multicentre trials. TRIAL REGISTRATION: The study protocol has been registered in PROSPERO (CRD42018099339).

"NEW" Prehabilitation: A 3-Way Approach to Improve Postoperative Survival and Health-Related Quality of Life in Cardiac Surgery Patients.

With advances in health care practices and delivery, the overall life expectancy of the Western population has increased. For those practitioners involved in the care of the patient with advanced cardiac disease, there has been a resultant higher prevalence of increasingly frail and older patients undergoing complex cardiac procedures. The higher rates of comorbid-associated higher vulnerability, with associated deconditioning, predisposes older, frail patients to poorer postoperative outcomes and a complicated recovery process after cardiac surgery. In addition, such patients experience inferior quality of life as a result of reduced ability to independently perform activities of daily living. During the preoperative waiting period, the cardiac symptoms and anxiety induces inactivity that in turn compounds the physical and mental deconditioning. To improve functional capacity and enhance postoperative recovery, prehabilitation, a component of the enhanced recovery after surgery model, might be of particular importance. In some studies, the preoperative improvement of the baseline physical, nutritional, and mental status has been reported to improve postoperative outcomes and enhance recovery after cardiac surgery. To address these domains, a 3-way approach to prehabilitation that is targeted toward improving nutritional status (N), exercise capacity (E) and worry reduction (W) (nutrition, exercise, and worry; "NEW" approach) might facilitate the perioperative management by ameliorating the postoperative outcomes and alleviating the surgical stress-related health deconditioning. In this review, the NEW approach and its potential benefits on postoperative outcomes as well as an implementation model (Promoting Action on Research Implementation in Health Services [PARiHS] framework) to aid institutional level implementation is described.
