Comparison of recovery patterns for patients undergoing coronary artery bypass grafting and minimally invasive direct coronary artery bypass in the early discharge period

Factors influencing physical activity engagement following coronary artery bypass graft surgery: A mixed methods systematic review

BACKGROUND

Engagement in physical activity during the initial months following coronary artery bypass graft (CABG) surgery is important in order to improve health, quality of life and functional outcomes. There are, however, many potential barriers to physical activity engagement during the recovery period. No review studies have focused on barriers and facilitators to engagement in physical activity during the early stages of recovery following CABG surgery.

OBJECTIVE

To explore the factors that influence engagement in physical activity during the first three months following CABG surgery.

METHODS

Four electronic databases were searched. Extracted data from selected studies were synthesised using the Joanna Briggs Institute convergent integrated approach.

RESULTS

Nineteen studies met the inclusion criteria. Four main themes that influenced engagement were identified: sociodemographic variables; physical symptoms; psychosocial factors; and environmental factors. More barriers were identified than facilitating factors. Psychosocial factors were the most commonly reported barriers in the literature.

CONCLUSIONS

The findings of this review provide insights into factors that inhibit and facilitate engagement in physical activity following CABG surgery. Further research specifically exploring factors that influence engagement, especially facilitators, is required.

Characterizing Patient-Centered Postoperative Recovery After Adult Cardiac Surgery: A Systematic Review

Background

Improving postoperative recovery is important, with a national focus on postacute care, but the volume and quality of evidence in this area are not well characterized. We conducted a systematic review to characterize studies on postoperative recovery after adult cardiac surgery using patient‐reported outcome measures.

Methods and Results

From MEDLINE and Web of Science, studies were included if they prospectively assessed postoperative recovery on adult patients undergoing cardiac surgery using patient‐reported outcome measures. Six recovery domains were defined by prior literature: nociceptive symptoms, mental health, physical function, activities of daily living, sleep, and cognitive function. Of the 3432 studies, 105 articles met the inclusion criteria. The studies were small (median sample size, 119), and mostly conducted in single‐center settings (n=81; 77%). Study participants were predominantly men (71%) and white (88%). Coronary artery bypass graft was included in 93% (n=98). Studies commonly selected for elective cases (n=56; 53%) and patients with less comorbidity (n=67; 64%). Median follow‐up duration was 91 (interquartile range, 42–182) days. Studies most commonly assessed 1 domain (n=42; 40%). The studies also varied in the instruments used and differed in their reporting approach. Studies commonly excluded patients who died during the follow‐up period (n=48; 46%), and 45% (n=47) did not specify how those patients were analyzed.

Conclusions

Studies of postoperative patient‐reported outcome measures are low in volume, most often single site without external validation, varied in their approach to missing data, and narrow in the domains and diversity of patients. The evidence base for postoperative patient‐reported outcome measures needs to be strengthened.

Examining symptom trajectories that predict worse outcomes in post-CABG patients

BACKGROUND

Coronary artery bypass grafting is one of the most common interventional revascularisation procedures used to treat coronary artery disease worldwide. With a wide variability in postoperative cardiac symptoms, identification of symptom trajectories during the 3-month postoperative recovery period may improve clinicians' abilities to support symptom recovery.

AIMS

To identify distinct trajectories of cardiac symptoms seen over time in a cohort of patients during the 3-month post-coronary artery bypass grafting period, and determine clinical characteristics associated with different symptom trajectories postoperatively.

METHODS

A prospective trial used the cardiac symptom survey to determine patient symptoms at baseline prior to surgery, and at 1 week, 6 weeks and 3 months following coronary artery bypass grafting. A latent class growth model and multivariate logistic regression analyses were used.

RESULTS

Data were obtained from patients ( N=198) undergoing coronary artery bypass grafting in six medical centres of Taiwan, through patient medical records and interviews. Based on their frequency, trajectories were explored for the six most common postoperative symptoms including angina, dyspnoea, fatigue, depression, sleep problems and anxiety. We identified two to three distinct classes of trajectories for each symptom. Age, longer intensive care unit stay, fewer vessels bypassed, off-pump coronary artery bypass grafting, smoking history and lack of regular exercise were associated with worse symptom outcome trends over time.

CONCLUSIONS

Using this unique trajectories-based research method, we are able to achieve a better understanding of symptom recovery patterns over time among coronary artery bypass grafting patients. Recognising risk factors and potential recovery patterns prior to surgery may allow healthcare providers to deliver targeted discharge planning and individualised care after coronary artery bypass grafting.

Technology-Enabled Remote Monitoring and Self-Management - Vision for Patient Empowerment Following Cardiac and Vascular Surgery: User Testing and Randomized Controlled Trial Protocol

Background

Tens of thousands of cardiac and vascular surgeries (CaVS) are performed on seniors in Canada and the United Kingdom each year to improve survival, relieve disease symptoms, and improve health-related quality of life (HRQL). However, chronic postsurgical pain (CPSP), undetected or delayed detection of hemodynamic compromise, complications, and related poor functional status are major problems for substantial numbers of patients during the recovery process. To tackle this problem, we aim to refine and test the effectiveness of an eHealth-enabled service delivery intervention, TecHnology-Enabled remote monitoring and Self-MAnagemenT—VIsion for patient EmpoWerment following Cardiac and VasculaR surgery (THE SMArTVIEW, CoVeRed), which combines remote monitoring, education, and self-management training to optimize recovery outcomes and experience of seniors undergoing CaVS in Canada and the United Kingdom.

Objective

Our objectives are to (1) refine SMArTVIEW via high-fidelity user testing and (2) examine the effectiveness of SMArTVIEW via a randomized controlled trial (RCT).

Methods

CaVS patients and clinicians will engage in two cycles of focus groups and usability testing at each site; feedback will be elicited about expectations and experience of SMArTVIEW, in context. The data will be used to refine the SMArTVIEW eHealth delivery program. Upon transfer to the surgical ward (ie, post-intensive care unit [ICU]), 256 CaVS patients will be reassessed postoperatively and randomly allocated via an interactive Web randomization system to the intervention group or usual care. The SMArTVIEW intervention will run from surgical ward day 2 until 8 weeks following surgery. Outcome assessments will occur on postoperative day 30; at week 8; and at 3, 6, 9, and 12 months. The primary outcome is worst postop pain intensity upon movement in the previous 24 hours (Brief Pain Inventory-Short Form), averaged across the previous 14 days. Secondary outcomes include a composite of postoperative complications related to hemodynamic compromise—death, myocardial infarction, and nonfatal stroke— all-cause mortality and surgical site infections, functional status (Medical Outcomes Study Short Form-12), depressive symptoms (Geriatric Depression Scale), health service utilization-related costs (health service utilization data from the Institute for Clinical Evaluative Sciences data repository), and patient-level cost of recovery (Ambulatory Home Care Record). A linear mixed model will be used to assess the effects of the intervention on the primary outcome, with an a priori contrast of weekly average worst pain intensity upon movement to evaluate the primary endpoint of pain at 8 weeks postoperation. We will also examine the incremental cost of the intervention compared to usual care using a regression model to estimate the difference in expected health care costs between groups.

Results

Study start-up is underway and usability testing is scheduled to begin in the fall of 2016.

Conclusions

Given our experience, dedicated industry partners, and related RCT infrastructure, we are confident we can make a lasting contribution to improving the care of seniors who undergo CaVS.

Patient recovery and transitions after hospitalization for acute cardiac events: an integrative review

Despite increased attention to providing seamless transitions after hospitalization, patients often feel unprepared, lack knowledge, and may be confused by what to expect during recovery at home after a cardiac event. Care transition after hospital discharge could be improved by informing and counseling patients more specifically about expected recovery after a cardiac event. Therefore, an integrative review of research was conducted to evaluate cardiac patients' trajectory of recovery after hospitalization. A total of 61 studies were included in this review. Studies included were those of cardiac patients who had been hospitalized for significant cardiac events and those focused on acute coronary syndrome (n = 18), percutaneous coronary intervention (PCI) (n = 12), cardiac surgery (coronary artery bypass surgery and valve surgery; n = 25), and heart failure (n = 6). Studies included quantitative, mixed-methods, and qualitative designs, with sample sizes ranging from 4 to 2121 participants. Notwithstanding the limitations of this review, findings demonstrated that patients' perceptions of their cardiac event evolved over time from uncertainty, fears, anxiety, and depression, which were often associated with a lack of knowledge of their cardiac condition, to a phase of self-management of their cardiac condition. Furthermore, patterns of commonly occurring symptoms and changes in functioning abilities during recovery after hospitalization were apparent among the different cardiac groups. These findings may be useful to both patients and clinicians to inform them about the recovery trajectory after a cardiac event to improve preparation for the transition from hospital to home.

Gender differences in recovery outcomes after an early recovery symptom management intervention

BACKGROUND

Despite known gender differences in recovery, few studies have examined symptom management (SM) interventions or responses by gender after coronary artery bypass surgery (CABS).

OBJECTIVE

The purpose of this subanalysis was to describe and evaluate differences in response by gender to an SM intervention on the presence and burden of symptoms, physical activity, and physical functioning in elderly CABS patients during the early discharge period (3 and 6 weeks after CABS, and 3 and 6 months after CABS).

METHODS

The parent study whose data were analyzed to examine gender differences involved a two-group, randomized clinical trial design. The 6-week early recovery SM telehealth intervention was delivered by the Health Buddy. Measures included the Cardiac Symptom Survey, a Modified 7-Day Activity Interview, an RT3 accelerometer, an Activity Diary, and the Medical Outcomes Study Short Form 36. This study was not powered for a gender × group analysis, and we used descriptive statistics, χ(2) tests, t tests, and analysis of variance for statistical analyses.

RESULTS

Subjects (n = 232) included 192 men and 40 women, with a mean age of 71.2 SD, 7 years. The intervention group consisted of 86 men and 23 women, and the usual care (UC) group consisted of 106 men and 17 women. Data trends suggest that the SM intervention exerted greater impact on women than on men for symptoms such as fatigue, depression, sleep problems, and pain. Again, men exhibited higher levels of physical activity than did women. However, women in the SM group generally had higher scores than did women in the UC group.

CONCLUSION

Although the parent study found no effect of an early recovery SM intervention, this exploratory secondary analysis indicated that women in the intervention group demonstrated more improvement in measures of physical activity than did those in the UC group. Further study, using a larger sample, is necessary to test these preliminary results.

Influence of a symptom management telehealth intervention on older adults' early recovery outcomes after coronary artery bypass surgery

OBJECTIVE

The study objective was to examine the effect of a symptom management (SM) telehealth intervention on physical activity and functioning and to describe the health care use of older adult patients (aged > 65 years) after coronary artery bypass surgery (CABS) by group (SM intervention group and usual care group).

METHODS

A randomized clinical trial design was used. The study was conducted in 4 Midwestern tertiary hospitals. The 6-week SM telehealth intervention was delivered by the Health Buddy (Health Hero Network, Palo Alto, CA). Measures included Modified 7-Day Activity Interview, RT3 accelerometer (Stayhealthy, Inc, Monrovia, CA), physical activity and exercise diary, Medical Outcomes Study Short-Form 36, and subjects' self-report and provider records of health care use. Follow-up times were 3 and 6 weeks and 3 and 6 months after CABS.

RESULTS

Subjects (N = 232) had a mean age of 71.2 (+4.7) years. There were no significant interactions using repeated-measures analyses of covariance. There was a significant group effect for average kilocalories/kilogram/day of estimated energy expenditure as measured by the RT3 accelerometer, with the usual care group having a higher estimated energy expenditure. Both groups had significant improvements over time for role-physical, vitality, and mental functioning. Both groups had similar health care use.

CONCLUSION

Subjects were able to return to preoperative levels of functioning between 3 and 6 months after CABS and to increase their physical activity over reported preoperative levels of activity. Further study of those patients undergoing CABS who could derive the most benefit from the SM intervention is warranted.

Influence of an early recovery telehealth intervention on physical activity and functioning after coronary artery bypass surgery among older adults with high disease burden

OBJECTIVE

Older adults with poor functioning preoperatively are at risk for delayed recovery and more impaired outcomes after coronary artery bypass surgery (CABS). The study objective was to determine whether a 6-week early recovery telehealth intervention, designed to improve self-efficacy and management related to symptoms after CABS, was effective in improving outcomes (physical activity, physiologic, and psychologic functioning) for older adults (aged > 65 years) with higher disease burden.

METHODS

A descriptive, repeated-measures experimental design was used. Follow-up data were collected at 3 and 6 weeks and 3 months after CABS. Subjects were drawn from a larger randomized clinical trial. Parent study subjects who had high disease burden preoperatively (physical component score of < 50 on the Medical Outcome Study Short Form-36 and RISKO score of > 6) were included (N = 55), with 23 subjects in the early recovery intervention group and 31 subjects in the usual care group (n = 31). Subjects ranged in age from 65 to 85 years (M = 71.6 + 5.1 years).

RESULTS

There was a significant main effect by group (F[1,209] = 4.66, P < .05). The intervention group had a least square means of 27.9 kcal/kg/d of energy expenditure compared with the usual care group of 26.6 kcal/kg/d per the RT3 accelerometer (Stayhealthy, Inc, Monrovia, CA). Both groups had significantly improved physical (F[2,171] = 3.26, P < .05) and role-physical (F[2,171] = 6.64, P < .005) functioning over time.

CONCLUSION

The subgroup of subjects undergoing CABS with high disease burden were responsive to an early recovery telehealth intervention. Improving patients' physical activity and functioning can reduce morbidity and mortality associated with poor functioning after cardiac events.

Relationships between fatigue and early postoperative recovery outcomes over time in elderly patients undergoing coronary artery bypass graft surgery

BACKGROUND

Despite successful coronary artery bypass graft (CABG) surgery, some patients continue to experience fatigue after their surgery.

OBJECTIVE

The purpose of this secondary analysis study was to examine the relationships of fatigue and early recovery outcomes (psychosocial and physiologic functioning, and physical activity) over time (6 weeks and 3 months) among older adult subjects, age 65 years and older, after CABG surgery. Comparison groups were those subjects who had fatigue at 3 weeks after surgery and nonfatigued subjects.

DESIGN

A prospective, comparative design was used for this secondary analysis study.

SAMPLE

Subjects in this study were drawn from the control group of subjects enrolled in the larger parent study. Subjects (N = 119) were dichotomized into fatigue (n = 66) and nonfatigued (n = 53) groups on the basis of their 3-week self-reports of postoperative fatigue.

RESULTS

At 6 weeks after surgery, fatigued subjects had significantly (P < .05) more impaired psychosocial functioning (role-emotional [t = 1.9], social [t = 2.6], and mental [t = 1.9] functioning) on the basis of the Medical Outcome Study Short Form 36. They had significantly (P < .005) higher mean hospital anxiety (t = -3.6) and depression (t = -2.9) subscale scores, respectively. Anxiety (t = -2.3, P < .05) remained significantly (P < .05) impaired at 3 months. At 6 weeks, role physical functioning, measured by the Medical Outcome Study Short Form 36, was significantly impaired (t = 2.4, P < .01). There were no significant differences in physical activity variables as measured by an RT3 accelerometer (Stayhealthy, Inc., Monrovia, CA) and self-report diary.

CONCLUSIONS

Persistent fatigue can hamper early recovery after CABG surgery. Tailored interventions are needed to address fatigue management and improve patient outcomes.

Development and content validity testing of the Cardiac Symptom Survey in patients after coronary artery bypass grafting

BACKGROUND

Patients who have undergone coronary artery bypass grafting often experience numerous symptoms after surgery. There is a need for a symptom tool for this population that is disease-specific, comprehensive, and responsive to change.

AIMS

The aims of this study were to describe the development and preliminary content validity testing of the Cardiac Symptom Survey (CSS), assess further content validity of the CSS through an expert panel, and assess responsiveness of the CSS to change.

METHODS

The original development of the CSS is described. An expert panel of four judges was used to rate the clarity of the items (content validity) and the relevance of the symptoms and items to the domain. Responsiveness to change of the CSS was assessed in a sample of 90 subjects who underwent coronary artery bypass grafting.

RESULTS

Percent agreement and content validity index coefficients ranged from .90 to 1.00. Repeated measures analyses of variance showed significant changes over time as hypothesized in some of the symptom evaluation and symptom response scores.

CONCLUSION

Support is documented for both content validity and responsiveness of the CSS.

Impact of an early recovery management intervention on functioning in postoperative coronary artery bypass patients with diabetes

BACKGROUND

Approximately 30% of patients undergoing coronary artery bypass graft (CABG) procedures have diabetes and, as such, are at increased risk for postoperative complications and a lengthy recovery.

OBJECTIVE

To test the feasibility of an in-home early recovery management intervention to improve physical and psychosocial functioning in the diabetic CABG population.

METHODS

This pilot study was a 2-group, randomized, experimental study. The 6-week in-home early recovery intervention was delivered by way of a device called the Health Buddy (Health Hero Network, Redwood City, CA). Subjects were 49 diabetic patients who had undergone a first-time CABG procedure.

RESULTS

Although no statistical differences between groups were found, descriptively, the intervention group's baseline means on Medical Outcomes Study Short Form-36 subscales measuring physical functioning were lower but improved to levels comparable with that of the control group. Improvements in psychosocial functioning were comparable between the 2 groups.

CONCLUSION

This in-home telehealth intervention may have promise for improving functioning outcomes in high-risk CABG patients with diabetes. However, weaknesses of the intervention and the need for a more focused, directive intervention were identified.

The effects of a symptom management intervention on symptom evaluation, physical functioning, and physical activity for women after coronary artery bypass surgery

The purpose of this subset analysis was to examine the effect of a symptom management (SM) intervention on postoperative symptom evaluation, physical functioning, and physical activity among the female participants (N = 40) of the larger parent study of coronary artery bypass graft patients aged 65 years and older. The intervention group (n = 23) had significantly lower fatigue scores at 6 weeks (Z = 1.96, P < .05) and higher levels of physical activity (Z = -1.71, P < .05) reflected in the expended kcal(-1) x kg x d(-1), as measured by the activity diary at 3 months after coronary artery bypass graft surgery. At 6 weeks and 3 months after surgery, there were significant correlations between cardiac surgery-related recovery symptoms (shortness of breath, fatigue, depression, incision pain, and sleep problems) and physical functioning (physical, vitality, and bodily pain functioning subscale scores), with correlations ranging from 0.31 to 0.46. Given that this was a subset analysis of a larger study, significant differences were not expected for all variables. Study findings support the need for a targeted (women-focused) and tailored (self-management recovery) intervention to assist females in recovering from coronary artery bypass graft surgery to improve symptom management, thereby enhancing physical functioning and physical activity outcomes.

Impact of a telehealth intervention to augment home health care on functional and recovery outcomes of elderly patients undergoing coronary artery bypass grafting

OBJECTIVE

This pilot study examined the effect of a home communication intervention (HCI) to augment home health care (HHC) on functioning and recovery outcomes of elderly patients undergoing coronary artery bypass graft.

DESIGN

A randomized, experimental two-group (N = 50) repeated-measures design was used. Both HCI and control subjects received HHC, and the HCI group also received the 12-week HCI delivered by a telehealth device, the Health Buddy (Health Hero Network). The Medical Outcome Study Short Form-36 measured physiologic and psychosocial functioning at baseline, 6 weeks, and 3 months after surgery. Follow-up subject interviews ascertained self-report of postoperative problems and health care use.

SAMPLE

Subjects had an average age of 75.3 years and included males (56%) and females (44%).

RESULTS

By using repeated-measures analyses of covariance, covariating for the total number of HHC visits, HCI subjects, compared with the HHC group only, had a significantly higher adjusted mean general health functioning score (F = 8.41 [1, 36], P < .01). There were significant time effects on physical, role-physical, and mental health functioning, indicating that both groups improved over time. The groups reported similar postoperative problems; however, the control group had more emergency department visits than the HCI group.

CONCLUSIONS

Findings demonstrate the potential benefit of using an HCI to further augment outcomes of high-risk patients undergoing coronary artery bypass graft surgery referred to HHC after hospitalization.

Correlates of Recovery Among Older Adults After Major Abdominal Surgery

BACKGROUND

Little research has examined the recovery patterns of older adults who have had major abdominal surgery.

OBJECTIVE

To determine whether pain, depression, and fatigue are significant factors in the return of older adults who had major abdominal surgery to functional status and self-perception of recovery in the first 3 months after discharge from the hospital.

METHODS

A correlational predictive study involved adults 60 years of age or older who had undergone major abdominal surgery. Data were collected during hospitalization (n = 192), then 3 to 5 days (n = 141), 1 month (n = 132), and 3 months after discharge to home (n = 126) using the Brief Pain Inventory, the Geriatric Depression Scale-Short Form, the Modified Fatigue Symptom Checklist, the Enforced Social Dependency Scale, and the Self-Perception of Recovery Scale.

RESULTS

Multiple regression analysis indicated that pain, depression, and fatigue are significantly related to patients' self-perception of recovery and functional status. Pain, depression, and fatigue explain 13.4% of the variation in functional status at 3 to 5 days, 30.8% at 1 month, and 29.1% at 3 months after discharge. These three factors also explain 5.6% of the variation in self-perception of recovery during hospitalization, 12.3% at 3 to 5 days, 33.2% at 1 month, and 16.1% at 3 months after discharge.

CONCLUSIONS

Pain, depression, and fatigue are important factors to consider in the provision of care to abdominal surgery patients with a relatively uncomplicated postoperative course. Specific interventions to reduce pain, depression, and fatigue need to be evaluated for their impact on the postoperative recovery of older adults.
