Prediction of quality of life after coronary artery bypass graft surgery: a review and evaluation of multiple, recent studies

Psychological interventions to foster resilience in healthcare students

BACKGROUND

Resilience can be defined as maintaining or regaining mental health during or after significant adversities such as a potentially traumatising event, challenging life circumstances, a critical life transition or physical illness. Healthcare students, such as medical, nursing, psychology and social work students, are exposed to various study- and work-related stressors, the latter particularly during later phases of health professional education. They are at increased risk of developing symptoms of burnout or mental disorders. This population may benefit from resilience-promoting training programmes.

OBJECTIVES

To assess the effects of interventions to foster resilience in healthcare students, that is, students in training for health professions delivering direct medical care (e.g. medical, nursing, midwifery or paramedic students), and those in training for allied health professions, as distinct from medical care (e.g. psychology, physical therapy or social work students).

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, 11 other databases and three trial registries from 1990 to June 2019. We checked reference lists and contacted researchers in the field. We updated this search in four key databases in June 2020, but we have not yet incorporated these results.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing any form of psychological intervention to foster resilience, hardiness or post-traumatic growth versus no intervention, waiting list, usual care, and active or attention control, in adults (18 years and older), who are healthcare students. Primary outcomes were resilience, anxiety, depression, stress or stress perception, and well-being or quality of life. Secondary outcomes were resilience factors.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data, assessed risks of bias, and rated the certainty of the evidence using the GRADE approach (at post-test only).

MAIN RESULTS

We included 30 RCTs, of which 24 were set in high-income countries and six in (upper- to lower-) middle-income countries. Twenty-two studies focused solely on healthcare students (1315 participants; number randomised not specified for two studies), including both students in health professions delivering direct medical care and those in allied health professions, such as psychology and physical therapy. Half of the studies were conducted in a university or school setting, including nursing/midwifery students or medical students. Eight studies investigated mixed samples (1365 participants), with healthcare students and participants outside of a health professional study field. Participants mainly included women (63.3% to 67.3% in mixed samples) from young adulthood (mean age range, if reported: 19.5 to 26.83 years; 19.35 to 38.14 years in mixed samples). Seventeen of the studies investigated group interventions of high training intensity (11 studies; > 12 hours/sessions), that were delivered face-to-face (17 studies). Of the included studies, eight compared a resilience training based on mindfulness versus unspecific comparators (e.g. wait-list). The studies were funded by different sources (e.g. universities, foundations), or a combination of various sources (four studies). Seven studies did not specify a potential funder, and three studies received no funding support. Risk of bias was high or unclear, with main flaws in performance, detection, attrition and reporting bias domains. At post-intervention, very-low certainty evidence indicated that, compared to controls, healthcare students receiving resilience training may report higher levels of resilience (standardised mean difference (SMD) 0.43, 95% confidence interval (CI) 0.07 to 0.78; 9 studies, 561 participants), lower levels of anxiety (SMD -0.45, 95% CI -0.84 to -0.06; 7 studies, 362 participants), and lower levels of stress or stress perception (SMD -0.28, 95% CI -0.48 to -0.09; 7 studies, 420 participants). Effect sizes varied between small and moderate. There was little or no evidence of any effect of resilience training on depression (SMD -0.20, 95% CI -0.52 to 0.11; 6 studies, 332 participants; very-low certainty evidence) or well-being or quality of life (SMD 0.15, 95% CI -0.14 to 0.43; 4 studies, 251 participants; very-low certainty evidence). Adverse effects were measured in four studies, but data were only reported for three of them. None of the three studies reported any adverse events occurring during the study (very-low certainty of evidence).

AUTHORS' CONCLUSIONS

For healthcare students, there is very-low certainty evidence for the effect of resilience training on resilience, anxiety, and stress or stress perception at post-intervention. The heterogeneous interventions, the paucity of short-, medium- or long-term data, and the geographical distribution restricted to high-income countries limit the generalisability of results. Conclusions should therefore be drawn cautiously. Since the findings suggest positive effects of resilience training for healthcare students with very-low certainty evidence, high-quality replications and improved study designs (e.g. a consensus on the definition of resilience, the assessment of individual stressor exposure, more attention controls, and longer follow-up periods) are clearly needed.

Psychological interventions to foster resilience in healthcare professionals

BACKGROUND

Resilience can be defined as the maintenance or quick recovery of mental health during or after periods of stressor exposure, which may result from a potentially traumatising event, challenging life circumstances, a critical life transition phase, or physical illness. Healthcare professionals, such as nurses, physicians, psychologists and social workers, are exposed to various work-related stressors (e.g. patient care, time pressure, administration) and are at increased risk of developing mental disorders. This population may benefit from resilience-promoting training programmes.

OBJECTIVES

To assess the effects of interventions to foster resilience in healthcare professionals, that is, healthcare staff delivering direct medical care (e.g. nurses, physicians, hospital personnel) and allied healthcare staff (e.g. social workers, psychologists).

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, 11 other databases and three trial registries from 1990 to June 2019. We checked reference lists and contacted researchers in the field. We updated this search in four key databases in June 2020, but we have not yet incorporated these results.

SELECTION CRITERIA

Randomised controlled trials (RCTs) in adults aged 18 years and older who are employed as healthcare professionals, comparing any form of psychological intervention to foster resilience, hardiness or post-traumatic growth versus no intervention, wait-list, usual care, active or attention control. Primary outcomes were resilience, anxiety, depression, stress or stress perception and well-being or quality of life. Secondary outcomes were resilience factors.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data, assessed risks of bias, and rated the certainty of the evidence using the GRADE approach (at post-test only).

MAIN RESULTS

We included 44 RCTs (high-income countries: 36). Thirty-nine studies solely focused on healthcare professionals (6892 participants), including both healthcare staff delivering direct medical care and allied healthcare staff. Four studies investigated mixed samples (1000 participants) with healthcare professionals and participants working outside of the healthcare sector, and one study evaluated training for emergency personnel in general population volunteers (82 participants). The included studies were mainly conducted in a hospital setting and included physicians, nurses and different hospital personnel (37/44 studies). Participants mainly included women (68%) from young to middle adulthood (mean age range: 27 to 52.4 years). Most studies investigated group interventions (30 studies) of high training intensity (18 studies; > 12 hours/sessions), that were delivered face-to-face (29 studies). Of the included studies, 19 compared a resilience training based on combined theoretical foundation (e.g. mindfulness and cognitive-behavioural therapy) versus unspecific comparators (e.g. wait-list). The studies were funded by different sources (e.g. hospitals, universities), or a combination of different sources. Fifteen studies did not specify the source of their funding, and one study received no funding support. Risk of bias was high or unclear for most studies in performance, detection, and attrition bias domains. At post-intervention, very-low certainty evidence indicated that, compared to controls, healthcare professionals receiving resilience training may report higher levels of resilience (standardised mean difference (SMD) 0.45, 95% confidence interval (CI) 0.25 to 0.65; 12 studies, 690 participants), lower levels of depression (SMD -0.29, 95% CI -0.50 to -0.09; 14 studies, 788 participants), and lower levels of stress or stress perception (SMD -0.61, 95% CI -1.07 to -0.15; 17 studies, 997 participants). There was little or no evidence of any effect of resilience training on anxiety (SMD -0.06, 95% CI -0.35 to 0.23; 5 studies, 231 participants; very-low certainty evidence) or well-being or quality of life (SMD 0.14, 95% CI -0.01 to 0.30; 13 studies, 1494 participants; very-low certainty evidence). Effect sizes were small except for resilience and stress reduction (moderate). Data on adverse effects were available for three studies, with none reporting any adverse effects occurring during the study (very-low certainty evidence).

AUTHORS' CONCLUSIONS

For healthcare professionals, there is very-low certainty evidence that, compared to control, resilience training may result in higher levels of resilience, lower levels of depression, stress or stress perception, and higher levels of certain resilience factors at post-intervention. The paucity of medium- or long-term data, heterogeneous interventions and restricted geographical distribution limit the generalisability of our results. Conclusions should therefore be drawn cautiously. The findings suggest positive effects of resilience training for healthcare professionals, but the evidence is very uncertain. There is a clear need for high-quality replications and improved study designs.

Quality of Life at Three Years after Cardiac Surgery: Relationship with Preoperative Status and Quality of Recovery

A reduction in symptoms, increased longevity, and improved quality of life (QoL), are goals of cardiac surgery. We measured QoL in 108 adult cardiac surgical patients at about three years after cardiac surgery, and assessed the predictive ability of a 40-item quality of recovery (QoR-40) score. Our follow-up rate was 86% (n=93). When compared with preoperative status, QoL was improved at three years after surgery (P<0.0005). The dimensions of QoL that were most affected were physical functioning, role limitations due to physical problems, vitality, social functioning, and role limitations due to emotional problems (all P<0.005). There was a mild correlation between the day 3 QoR-40 and the three year SF-36, r=0.23 (P=0.029). There was a strong correlation between the three year QoR-40 and the three year SF-36, r=0.73 (P<0.0005). The QoR-40 and SF-36 done at three years after cardiac surgery demonstrated good internal consistency, QoR-40 α=0.86 (P<0.0005), SF-36 α=0.91 (P<0.0005). A poor quality recovery in the days after surgery can predict a poor QoL at three years after surgery. The QoR-40 is a valid and reliable measure of quality of recovery after surgery and anaesthesia. The QoR-40 is a useful, patient-oriented method of assessing recovery from anaesthesia and surgery.

Coronary Artery Bypass Graft Operation: Patients' Experience of Health and Well-Being Over Time

BACKGROUND

The aim of the coronary artery bypass graft operation is to relieve anginal symptoms and improve functional ability, quality of life and survival. However, having the surgery does not always have the desired outcomes. Although numerous studies have investigated the outcomes of coronary artery bypass graft operation, little attention has been given to patients' perceptions of the outcomes or effects of the operation on health and well-being over time.

AIM

To explore patients' perspectives on the effects of coronary artery bypass surgery on health and well-being over time.

METHODS

As part of a larger mixed methods study, 62 in-depth audio-taped interviews with men and women who had undergone coronary artery bypass approximately 7 years earlier were conducted. Interviews were audio-taped and transcribed. Data were analysed thematically. This paper reports the findings from the qualitative component of the larger study.

FINDINGS

The four main themes: 'Recovery and Rehabilitation', 'Seven Years On', 'Maintaining a Positive Approach', and 'Health Behaviour Change' reflect the main areas of focus emerging across the interviews and provide credible overarching descriptors of the sub-themes they encompass. The 11 sub-themes identified were recognised as central to the patients' experiences of their health and well-being over the longer-term.

CONCLUSIONS

Although most patients report improved health and well-being after coronary artery bypass operation, many have described their recovery and rehabilitation as a complex process with both short and long term effects. The insights provided by participants help improve our understanding of the impact of the operation on patients' health and well-being over time. We believe these insights will help us to anticipate the possible needs of future patients and enable us develop appropriate interventions that may facilitate self-management for optimal recovery and health maintenance.

Adult Congenital Heart Disease-Coping And REsilience (ACHD-CARE): Rationale and methodology of a pilot randomized controlled trial

INTRODUCTION

One-third of North American adults with congenital heart disease (CHD) have diagnosable mood or anxiety disorders and most do not receive mental health treatment. There are no published interventions targeting the psychosocial needs of patients with CHD of any age. We describe the development of a group psychosocial intervention aimed at improving the psychosocial functioning, quality of life, and resilience of adults with CHD and the design of a study protocol to determine the feasibility of a potential full-scale randomized controlled trial (RCT).

METHODS/DESIGN

Drawing upon our quantitative and qualitative research, we developed the Adult CHD-Coping And REsilience (ACHD-CARE) intervention and designed a feasibility study that included a 2-parallel arm non-blinded pilot RCT. Eligible participants (CHD, age ≥ 18 years, no planned surgery, symptoms suggestive of a mood and/or anxiety disorder) were randomized to the ACHD-CARE intervention or Usual Care (1:1 allocation ratio). The group intervention was delivered during eight 90-minute weekly sessions. Feasibility will be assessed in the following domains: (i) process (e.g. recruitment and retention), (ii) resources, (iii) management, (iv) scientific outcomes, and (v) intervention acceptability.

DISCUSSION

This study underscores the importance of carefully developing and testing the feasibility of psychosocial interventions in medical populations before moving to full-scale clinical trials. At study conclusion, we will be poised to make one of three determinations for a full-scale RCT: (1) feasible, (2) feasible with modifications, or (3) not feasible. This study will guide the future evaluation and provision of psychosocial treatment for adults with CHD.

Health-related personal control predicts depression symptoms and quality of life but not health behaviour following coronary artery bypass graft surgery

To determine the prospective association between health-related control beliefs, quality of life (QOL), depression symptoms, and health behaviours in coronary artery bypass graft (CABG) patients 6-8 weeks following surgery. 149 patients who were undergoing planned CABG surgery were recruited. Patients completed questionnaires measuring health related personal control, treatment control, depression symptoms, QOL, and health behaviours prior to and 6-8 weeks after surgery. Higher levels of health-related personal control predicted better QOL, and lower levels of depression symptoms, but not adherence to medication, cardiac rehabilitation attendance, or physical activity. These results were independent of demographic, behavioural, and clinical covariates. Treatment control was not associated with any outcome. These results suggest that perceived health-related personal control is associated with key aspects of short-term recovery from CABG surgery. Targeted interventions aimed at improving perceptions of health-related personal control may improve health outcomes in this cardiac population.

The intensive care unit psychosocial care scale: Development and initial validation

The main objective of the current study was to construct a new self-report scale - ICU-PC Scale - to measure the psychosocial care (PC) of patients in Intensive Care Unit (ICU) and examine different psychometric issues in the development and initial validation of this scale. The findings indicate that the ICU-PC Scale has established high internal consistency. A three-factor structure - protection of human dignity and rights, transparency for decision making and care continuity and sustained patient, family orientation - has been identified with a substantial number of subjects (N=250) in hospital settings. The three oblique factor solutions are found to be interrelated and interdependent with good indices of internal consistency and content validity. This new instrument is the first of its kind to measure the psychosocial care to be provided to patients in the ICU. The present findings indicate that the ICU-PC scale, with additional factor analytic research, could become an established and clinical tool.

Presurgical Psychological and Neuroendocrine Predictors of Psychiatric Morbidity After Major Vascular Surgery: A Prospective Longitudinal Study

OBJECTIVES

Major life stressors, including major surgeries, are often followed by psychiatric symptoms and disorders. Prior retrospective work found abdominal aortic aneurysm (AAA) repair is followed by increased psychiatric morbidity, which may adversely influence physical and functional recovery. Identifying risk factors before surgery, such as dysregulation in stress response systems, might be useful in improving preventative intervention.

METHODS

Two hundred sixteen patients receiving open AAA or aortofemoral bypass surgeries, endovascular AAA repair, or nonsurgical AAA treatment were recruited from two vascular surgery services. Psychiatric symptoms and salivary cortisol measures (waking, 4 PM, and 11 PM, before and after low-dose dexamethasone) were obtained at intake and 3- and 9-month follow-ups.

RESULTS

After open surgeries, 18% of patients had new psychiatric disorders, compared with 4% of patients receiving endovascular AAA repair or nonsurgical treatment (odds ratio = 6.0, 95% confidence interval = 1.6-22.1, p = .007). Having a history of major depression predicted the onset of new disorders in surgical patients. Presurgical cortisol levels were associated with both baseline (r = 0.23, p < .05) and 9-month (r = 0.32, p < .01) psychiatric symptoms (cortisol B = 1.0, standard error = 0.48, p < .05, in repeated-measures mixed model).

CONCLUSIONS

Open AAA repair surgery is prospectively linked to the development of psychiatric morbidity, and history of depression elevates risk. Cortisol measures before surgery are associated with current and future psychological functioning, suggesting potential neurobiological mechanisms that may contribute to vulnerability. These results can help identify surgical patients at risk and point to potential targets for risk reduction interventions.

Preexisting cognitive status is associated with reduced behavioral functional capacity in patients 3 months after cardiac surgery: an extension study

OBJECTIVE

To examine whether preexisting cognitive status rather than short- and middle-term postoperative cognitive decline (POCD) may differentially account for behavioral functional capacity 3 months after cardiac surgery.

METHOD

Seventy-nine patients completed a psychological evaluation, including the Trail Making Test Part B, the memory with 10-s interference, the phonemic fluency and the Instrumental Activities of Daily Living (IADLs) questionnaire for cognitive functions and behavioral functional capacity, respectively, before surgery, at discharge and at 3-month follow-up.

RESULTS

Thirty-one (39%) and 22 (28%) patients showed POCD at discharge and at 3-month follow-up, respectively. Preoperative cognitive status was significantly associated with change in behavioral functional capacity 3 months after surgery (Ps<.003), whereas short- and middle-term POCD and intraoperative risk factors were unrelated to residualized change in IADLs scores (all Ps>.095).

CONCLUSIONS

Preexisting cognitive deficit, especially working memory deficit, rather than short- and middle-term POCD related to intraoperative risk factors is associated with poor behavioral functional capacity 3 months after cardiac surgery. The present study therefore suggests that a preoperative cognitive evaluation is essential to anticipate which patients are likely to show a decline in behavioral functional capacity after cardiac surgery.

Relation of depression, anxiety, and quality of life with outcome after percutaneous transluminal coronary angioplasty

Background. Despite, increasing number of percutaneous transluminal coronary angioplasty (PTCA) being performed, there is a paucity of Indian studies on the psychological effects of PTCA. Aim. To study the relation of anxiety, depression, and health related quality of life with outcome after PTCA. Methods. A total of 35 patients undergoing PTCA were included in the present project with their informed consent. All patients filled a specially designed proforma, the Hospital Anxiety and Depression Scale, Coronary Scale, Seattle Angina Questionnaire, and a health related quality of life measure (EQ 5D) one day before undergoing PTCA. Three days after PTCA patients were reassessed with the Hospital anxiety & depression scale, Seattle angina questionnaire and the EQ 5D. Results. Analysis showed that 46% had significant anxiety and 32.1% had significant depression before PTCA. Following successful PTCA, none of the patients had significant anxiety, and only 2 (3.6%) had significant depression. On the Seattle Angina Questionnaire, physical limitation reduced from 67.9 to 48. Disease perception improved from 21.2 to 37.1. On the EQ5D, the health status improved from 42.7 before PTCA to 78.7 after PTCA. Conclusion. Successful PTCA resulted in significant reduction in anxiety, depression, and physical limitation and improvement in disease perception and health status.

Psychosocial aspects of children and families of children treated with automated peritoneal dialysis

BACKGROUND

The aim of this study was to analyze psychosocial aspects of chronic kidney disease (CKD) in children treated with automated peritoneal dialysis (APD).

METHODS

The study assessed 41 children > 2 (range 2.1-18) years of age and their parents. Data concerning the illness and sociodemographic parameters were collected. Patients completed the Paediatric Quality of Life Inventory (PedsQL) and their parents the PedsQL-proxy version, General Health Questionnaire (GHQ-12), Berlin Social Support Scales (BSSS), and Caregiver's Burden Scale (CBS).

RESULTS

Parents rated their children's overall health-related quality of life (QoL) as well as their physical and emotional functioning lower than the patients themselves. The majority of primary caregivers had a medium level of the total burden index in the CBS and higher values in the scales need for support and perceived available support than in the received support (BSSS). In the GHQ-12, 51.2% of primary caregivers had scores >2 points, which indicated the possible occurrence of abnormal mental functioning.

CONCLUSIONS

Financial support for patients' families is necessary. Parents who provide primary care to children on PD require, above all, emotional support and assistance in self-fulfilment. More than half of them may have impaired mental function. There is the strong need to provide continuous psychological care for caregivers. Differences in perception of the children's activity in varied areas by the patients themselves and their caregivers may contribute to further problems within families.

Myocardial revascularization for the elderly: current options, role of off-pump coronary artery bypass grafting and outcomes

The increase in life expectancy has confronted cardiac surgery with a rapidly growing population of elderly patients requiring surgical myocardial revascularization. Recent advances in surgical and anesthetic techniques and improvements in postoperative care have made coronary artery bypass grafting an established therapeutic option for the treatment of coronary artery disease in this group of patients. However, conventional coronary artery bypass grafting on cardiopulmonary bypass is associated with significant risk and related morbidity and mortality in the elderly. In recent years off-pump coronary artery bypass grafting has emerged as a safe and less invasive strategy for surgical myocardial revascularization. Off-pump coronary artery bypass grafting by avoiding the deleterious effects of cardiopulmonary bypass can offer potential benefits to elderly patients requiring surgical myocardial revascularization. This review article provides an overview of the age-related cardiovascular changes, epidemiology of coronary artery disease in the elderly and focuses on outcomes of surgical myocardial revascularization with special emphasis on the impact of off-pump coro-nary artery bypass surgery in the elderly.

Change in behavioral functional capacity is associated with preexisting cognitive function rather than with cognitive decline in patients 1 year after cardiac surgery

OBJECTIVE

The objective was to examine whether preexisting cognitive function rather than cognitive decline associated with intraoperative procedures may predict change in behavioral functional capacity in patients 1 year after cardiac surgery.

METHOD

Forty-five patients completed a cognitive evaluation, including the Trail Making Test part B (TMT-B) for attention and psychomotor speed, the Memory with 10-s interference for working memory, the Digit Span test for short-term memory and the Instrumental Activities of Daily Living (IADLs) questionnaire for behavioral functional capacity, before surgery and 1 year after cardiac surgery.

RESULTS

Sixteen patients (36%) exhibited cognitive decline after cardiac surgery. Preoperative scores on TMT-B significantly predicted change in behavioral functional capacity as measured by IADLs (beta = 0.371, P < .05), whereas the postoperative cognitive decline and intraoperative variables were unrelated to residualized change scores in IADLs (all Ps > .08).

CONCLUSIONS

Preexisting cognitive dysfunctions as assessed by TMT-B can be a marker of preoperative brain dysfunction, which, in turn, in addition to brain damage caused by cardiac surgery procedures, may further predispose patients to poor behavioral functional capacity and outcome 1 year after surgery. Impaired cognitive functions before surgery should be considered when evaluating the effects of cardiac surgery procedures on long-term behavioral functional status of patients.

The role of depressive and anxiety symptoms in the evaluation of cardiac rehabilitation efficacy after coronary artery bypass grafting surgery

OBJECTIVES

The aim of this study was to evaluate the efficacy of early 3-week cardiac rehabilitation (CR) in terms of the reduction of negative psychological symptoms, and to determine which factors predispose patients to worse rehabilitation results in this regard.

METHODS

The study involved a random group of 50 patients (11 women and 39 men) who had undergone coronary artery bypass grafting, with a mean age of 63.3 (± 7.2) years. The following screening tests were used: Beck Depression Inventory, State-Trait Anxiety Inventory and Acceptance of Illness Scale. The pulse rate during the first session of physical training was recorded (t(1) P), and after training the patients assessed their level of exertion (t(1) E) on the Borg Scale (BS). The same procedure was repeated at the end of the rehabilitation (t(2) P, t(2) E).

RESULTS

Among the psychological parameters examined at t(1) (at baseline), the strongest relationship with poor acceptance of illness after 3 weeks of rehabilitation was indicated by the level of depression (P < 0.001), with a slightly lower correlation with the state anxiety and the trait anxiety results (P = 0.005 and 0.027, respectively). A relationship was also found between the severity of depression in t(1) and the level of exertion measured by the BS at the end of rehabilitation (P = 0.007). Before rehabilitation, depressed patients exhibited higher levels of both trait and state anxiety (P = 0.009 and 0.018, respectively). After rehabilitation in the depressed subgroup, there was no improvement in the subjective assessment of exertion or reduction of state anxiety. Sex and co-morbidities also had considerable importance in the context of CR efficacy. The women showed more severe depressive symptoms (P = 0.01), a higher personality tendency to anxiety (P = 0.036) and poorer results of rehabilitation (in relation to the level of exertion after physical training and the intensity of state anxiety symptoms). There was no reduction of state anxiety in patients who suffered from at least two co-morbidities.

CONCLUSIONS

The presence of severe anxiety-depressive symptoms before rehabilitation has an effect on its outcome. Psychiatric symptomatology should be diagnosed as early as possible and patients should receive additional therapeutic support.

Prognostic value of preoperative quality of life on mortality after isolated elective myocardial revascularization

OBJECTIVES

This study evaluates whether a low preoperative quality of life (QoL), measured with the EuroQoL instruments EQ-5D and EQ-visual analogue scale (VAS) can be used as a predictor of mortality after elective isolated myocardial revascularization.

METHODS

A total of 2501 patients, with a mean age of 65.3 ± 9.4 (range 18-93) years and a mean additive EuroSCORE of 2.7 ± 2.1 (0-12), undergoing an elective isolated coronary artery bypass graft between January 2002 and June 2011 completed preoperative EQ-5D and EQ-VAS.

RESULTS

Hospital mortality [1.0% (25/2501 patients)] and 30-day mortality [1.2% (29/25 patients)] were the studied outcomes. The EQ-5D was 0.69 ± 0.26 (-0.30 to 1.0) with a median of 0.77 and the EQ-VAS was 59.7 ± 22.4 (0-100) with a median of 60. Regression analysis showed a significant correlation between hospital mortality and EQ-5D (P = 0.016) and EQ-VAS (P = 0.033). There is a significant correlation between 30-day mortality and EQ-5D (P = 0.048), but not for EQ-VAS (P = 0.06). The c-statistics (95% confidence interval) for EQ-5D and EQ-VAS for predicting hospital mortality are 0.36 (0.24-0.46) and 0.33 (0.23-0.42), respectively. The c-statistics for predicting 30-day mortality are 0.39 (0.30-0.49) for EQ-5D and 0.35 (0.26-0.44) for EQ-VAS.

CONCLUSIONS

Based on these results, we conclude that, in isolation, poor low preoperative EQ-5D and EQ-VAS scores do not contribute to deciding which patients should undergo cardiac surgery.

Fatigue of survivors following cardiac surgery: positive influences of preoperative prayer coping

OBJECTIVES

Fatigue symptoms are common among individuals suffering from cardiac diseases, but few studies have explored longitudinally protective factors in this population. This study examined the effect of preoperative factors, especially the use of prayer for coping, on long-term postoperative fatigue symptoms as one aspect of lack of vitality in middle-aged and older patients who survived cardiac surgery.

METHOD

The analyses capitalized on demographics, faith factors, mental health, and on medical comorbidities previously collected via two-wave preoperative interviews and standardized information from the Society of Thoracic Surgeons' national database. The current participants completed a mailed survey 30 months after surgery. Two hierarchical regressions were performed to evaluate the extent to which religious factors predicted mental and physical fatigue, respectively, after controlling for key demographics, medical indices, and mental health.

RESULTS

Preoperative prayer coping, but not other religious factors, predicted less mental fatigue at the 30-month follow-up, after controlling for key demographics, medical comorbidities, cardiac function (previous cardiovascular intervention, congestive heart failure, left ventricular ejection fraction, New York Heart Association Classification), mental health (depression, anxiety), and protectors (optimism, hope, social support). Male gender, preoperative anxiety, and reverence in secular context predicted more mental fatigue. Physical fatigue increased with age, medical comorbidities, and preoperative anxiety. Including health control beliefs in the model did not eliminate this effect.

CONCLUSIONS

Prayer coping may have independent and positive influences on less fatigue in individuals who survived cardiac surgery. However, future research should investigate mechanisms of this association.

Posttraumatic growth in patients who survived cardiac surgery: the predictive and mediating roles of faith-based factors

Despite the growing knowledge of posttraumatic growth, only a few studies have examined personal growth in the context of cardiac health. Similarly, longitudinal research is lacking on the implications of religion/spirituality for patients with advanced cardiac diseases. This paper aims to explore the effect of preoperative religious coping on long-term postoperative personal growth and potential mediation in this effect. Analyses capitalized on a preoperative survey and medical indices from the Society of Thoracic Surgeons' National Database of patients undergoing cardiac surgery. Participants in the current follow-up study completed a mailed survey 30 months after surgery. Hierarchical regression analysis was performed to evaluate the extent to which preoperative use of religious coping predicted growth at follow-up, after controlling for key demographics, medical indices, mental health, and protective factors. Predictors of posttraumatic growth at follow-up were positive religious coping and a living status without a partner. Medical indices, optimistic expectations, social support, and other religious factors were unrelated to posttraumatic growth. Including religious factors diminished effects of gender, age, and race. Including perceived spiritual support completely eliminated the role of positive religious coping, indicating mediation. Preoperative positive religious coping may have a long-term effect on postoperative personal growth, explainable by higher spiritual connections as a part of significance-making. These results suggest that spirituality may play a favorable role in cardiac patients' posttraumatic growth after surviving a life-altering operation. The elimination of demographic effects may help explain previously mixed findings concerning the association between these factors and personal growth.

Does type-D personality predict outcomes among patients with cardiovascular disease? A meta-analytic review

OBJECTIVE

Research generally indicates that psychological variables are stronger predictors of cardiovascular outcomes in healthy populations than in those with preexisting illness. Studies of Type-D personality, however, suggest that it may also be predictive of negative health outcomes in cardiovascular patient populations. To date, no independent, comprehensive meta-analysis centered specifically on Type-D has integrated this literature and provided quantitative estimates of these relationships. The present meta-analysis investigated the associations between Type-D personality and (a) major adverse cardiac events (MACE), (b) health-related quality of life (HRQOL) and (c) biochemical markers of cardiovascular disease among cardiovascular patients.

METHOD

Two independent reviewers abstracted data from 15 separate studies. A random effects meta-analytic model was utilized to calculate omnibus effect sizes for each set of related studies, i.e., for the MACE (N of patients=2903), HRQOL (N of patients=1263) and biochemical marker (N of patients=305) measures.

RESULTS

A positive association was found between Type-D personality and MACE, whereas a negative association was observed between Type-D personality and HRQOL. There was a trend toward significance in the association between Type-D personality and cardiovascular disease biomarkers.

CONCLUSION

Type-D personality is a promising construct for understanding psychological relationships with important outcomes among cardiovascular patients. Subsequent investigations undertaken by a more diverse group of unaffiliated scientists are important for further development in this line of research.

Psychological Correlates of Outcome after Coronary Artery Bypass Graft

BACKGROUND

Psychological effects of Coronary Artery Bypass graft (CABG) have been of interest all over the world but there is a paucity of Indian work.

METHODS

30 patients undergoing CABG at a service hospital were included. All patients filled a specially designed proforma. Mini Mental Status Examination, Hospital anxiety and depression scale, Coronary scale, Seattle angina questionnaire and Euro-QOL 5D were performed before and seven days after CABG.

RESULTS

43.3% had significant anxiety and 30% had significant depression before CABG. Following CABG, 36.67% of the patients had significant anxiety while 40% had significant depression. On the Seattle angina questionnaire, physical limitation reduced from 71.6 ± 7.9 to 53.1 ± 14.6. There was significant improvement in treatment satisfaction from 37.8 ± 6.1 to 59.4 ± 4.2 following CABG. On th euro quality of life scale (EQ5D) health status improved from 38.17 ± 9.51 before CABG to 68.5 ± 5.28 after CABG.

CONCLUSION

There is a significant incidence of anxiety and depression in patients undergoing CABG, both before and after surgery.

A multinational study of the influence of health-related quality of life on in-hospital outcome after coronary artery bypass graft surgery

BACKGROUND

The effect of health-related quality of life on in-hospital outcomes after coronary artery bypass grafting surgery has not been investigated in international multicenter studies. We hypothesized that poor preoperative health status is associated with mortality and length of hospital stay.

METHODS

In the Multicenter Study of Perioperative Ischemia Epidemiology II, preoperative Short-Form 12, Mental Component Summary (MCS), and Physical Component Summary (PCS) scores were obtained prospectively from 4,811 patients (3,834 men, 977 women) undergoing coronary artery bypass grafting surgery at 72 centers in 17 countries. Primary outcome measures were in-hospital mortality and prolonged (>14 days) length of hospital stay.

RESULTS

One hundred fifty-one patients (3.1%) died. After adjustment for regional differences, a 10-point reduction in MCS score was associated with higher mortality risk (odds ratio [OR] 1.17, 95% CI 1.004-1.37, P = .04) and prolonged hospital stay (OR 1.11, 95% CI 1.01-1.21, P = .03). The preoperative PCS score was not associated with mortality risk but significantly predicted prolonged length of hospital stay (OR 1.20, 95% CI 1.09-1.33, P < .001). There was no significant interaction between gender and either the MCS or the PCS score.

DISCUSSION

The preoperative PCS predicted prolonged postoperative hospital stay, whereas the preoperative MCS score was an independent predictor of both prolonged length of hospital stay and mortality. Preoperative assessment of health-related quality of life factors with the Short-Form 12 might be a useful tool for risk stratification and planning for hospital discharge and rehabilitation.

Depression following open-heart surgery: a path model involving interleukin-6, spiritual struggle, and hope under preoperative distress

Faith factors (i.e., factors pertaining to religion/spirituality) have been linked with well-being and adequate coping. Few studies have investigated negative aspects of religious coping, such as spiritual struggle. Based on the multidisciplinary literature and on previous findings, the study's analysis estimated parallel psychophysiological pathways from preoperative distress to postoperative depression in patients undergoing open heart surgery. Plasma samples for interleukin(IL)-6 were obtained before surgery. The results showed that a link between spiritual struggle and IL-6 mediated the indirect effects of preoperative anxiety on postoperative depression. Avoidant coping also mediated the influence of anxiety on postoperative maladjustment. Further, hope played a protective mediating role to moderate the undesirable influences of the spiritual struggle-IL-6 link and maladaptive coping on postoperative mental health attributes.

Information level of patients in discharge training given by nurses following open heart surgery

Providing discharge information following a surgery is one of the most common nursing approaches. Patients should be given discharge training after open heart surgery in order to eliminate or reduce physical and emotional problems. The study aims to assess the information level of patients in discharge training provided by nurses following open heart surgery. The study is a prospective study including 50 patients who underwent open heart surgery. The information level of patients who received discharge training was assessed before training and 1 month after the training. Data were collected using the personal information form, and pretest and post-test questionnaires. Data were assessed by using percentage, McNemar chi-squared, Wilcoxon signed ranks and stepwise linear regression analysis tests. Results indicated that patients were well informed following discharge training (Z = -6.166, P < 0.05), and that age and marriage variables affected the information level (P = 0.032, P = 0.045, respectively). Discharge training following open heart surgery increases the knowledge of patients and should be given to patients in a planned manner.

A systematic review of pre-operative predictors of post-operative depression and anxiety in individuals who have undergone coronary artery bypass graft surgery

In addition to the physical benefits, another important objective of coronary artery bypass graft (CABG) surgery is improvement of health-related quality of life. The aim of this systematic review is to provide an overview of the literature relating to the pre-operative prediction of post-operative depression and anxiety in individuals who have undergone CABG surgery. Forty-six studies were identified through a literature search of electronic databases conducted using explicit inclusion and exclusion criteria. The study characteristics, methodological features, and psychometric and clinical outcomes were summarised in a systematic manner. Collective appraisal of the studies indicated that symptoms of depression and anxiety exhibited after CABG surgery are best predicted by pre-operative measures of functioning in that area. Papers were inconclusive with respect to the predictive qualities of gender and age. Further research is required to clarify the predictive values of these and other factors, including pre-morbid ill health and socio-economic status. The findings of this review indicate a range of pre-operative predictors of post-operative depression and anxiety in patients with CABG. Chief among these are pre-operative depression and anxiety. These findings have clinical implications concerning the importance of pre and post-operative psychological assessment and intervention for individuals at risk of poor psychological recovery.

Long-term Adjustment After Surviving Open Heart Surgery: The Effect of Using Prayer for Coping Replicated in a Prospective Design

PURPOSE

despite the growing evidence for effects of religious factors on cardiac health in general populations, findings are not always consistent in sicker and older populations. We previously demonstrated that short-term negative outcomes (depression and anxiety) among older adults following open heart surgery are partially alleviated when patients employ prayer as part of their coping strategy. The present study examines multifaceted effects of religious factors on long-term postoperative adjustment, extending our previous findings concerning prayer and coping with cardiac disease.

DESIGN AND METHODS

analyses capitalized on a preoperative survey and medical variables from the Society of Thoracic Surgeons' National Database of patients undergoing open heart surgery. The current participants completed a mailed survey 30 months after surgery. Two hierarchical regressions were performed to evaluate the extent to which religious factors predicted depression and anxiety, after controlling for key demographics, medical indices, and mental health.

RESULTS

predicting lower levels of depression at the follow-up were preoperative use of prayer for coping, optimism, and hope. Predicting lower levels of anxiety at the follow-up were subjective religiousness, marital status, and hope. Predicting poorer adjustment were reverence in religious contexts, preoperative mental health symptoms, and medical comorbidity. Including optimism and hope in the model did not eliminate effects of religious factors. Several other religious factors had no long-term influences. MPLICATIONS: the influence of religious factors on the long-term postoperative adjustment is independent and complex, with mediating factors yet to be determined. Future research should investigate mechanisms underlying religion-health relations.

Health-related quality of life after fast-track treatment results from a randomized controlled clinical equivalence trial

PURPOSE

This randomized clinical equivalence trial was designed to evaluate health-related quality of life (HRQoL) after fast-track treatment for low-risk coronary artery bypass (CABG) patients.

METHODS

Four hundred and ten CABG patients were randomly assigned to undergo either short-stay intensive care treatment (SSIC, 8 h of intensive care stay) or control treatment (care as usual, overnight intensive care stay). HRQoL was measured at baseline and 1 month, and one year after surgery using the multidimensional index of life quality (MILQ), the EQ-5D, the Beck Depression Inventory and the State-Trait Anxiety Inventory.

RESULTS

At one month after surgery, no statistically significant difference in overall HRQoL was found (MILQ-score P-value=.508, overall MILQ-index P-value=.543, EQ-5D VAS P-value=.593). The scores on the MILQ-domains, physical, and social functioning were significantly higher at one month postoperatively in the SSIC group compared to the control group (P-value=.049; 95%CI: 0.01-2.50 and P-value=.014, 95% CI: 0.24-2.06, respectively). However, these differences were no longer observed at long-term follow-up.

CONCLUSIONS

According to our definition of clinical equivalence, the HRQoL of SSIC patients is similar to patients receiving care as usual. Since safety and the financial benefits of this intervention were demonstrated in a previously reported analysis, SSIC can be considered as an adequate fast-track intensive care treatment option for low-risk CABG patients.

Negative emotions and quality of life six months after cardiac surgery: the dominant role of depression not anxiety symptoms

The specific syndromal aspects of depression and anxiety have not been explored in relation to changes in health related quality of life (HRQOL) after cardiac surgery. The purpose of this study was to examine the impact of general stress, depression and anxiety on HRQOL after coronary artery bypass graft (CABG) surgery. Utilizing a tripartite conceptual model of depression and anxiety, it was hypothesized that general stress symptoms, rather than unique depressive or anxiogenic symptoms, would be associated with lower HRQOL 6 months after CABG surgery. Elective CABG patients (n=226) completed baseline and postoperative self-report measures of negative emotions and HRQOL, and 193 patients completed these measures at 6-month follow-up. Multiple linear regression analyses and logit link analyses were performed to test the hypothesis. Elevated depression symptoms before and after surgery showed an association with lower and worse HRQOL for vitality and social role functioning and physical and general health. This study adds to previous research by outlining discrete associations between specific HRQOL domains, and is perhaps the first to test a theoretical model of depression and anxiety in relation to cardiac CABG patients' perceptions of HRQOL. These findings encourage further research on negative emotions and HRQOL in cardiac surgery patients and the practical implications of these findings are discussed.

Health-related quality of life three years after coronary surgery: A comparison with the general population

OBJECTIVES

To assess health-related quality of life (HRQOL) in patients three years after coronary artery bypass grafting (CABG) compared to the general Norwegian population, with emphasis on age and gender-differences.

DESIGN

A cross-sectional postal survey of patients who underwent CABG in 2000. HRQOL was assessed using the Short Form 36 (SF-36). Subgroup analyses were performed according to age (<70 versus =70 years) and gender.

RESULTS

Of 233 eligible patients 203 responded (mean age 67.6 years, 17% females). Patients reported better scores on bodily pain than the general population (p=0.008), but did not differ on other subscales of SF-36. Younger patients tended to score lower, older patients higher than the general population on HRQOL. Female patients reported lower HRQOL than the general female population and reported significantly lower scores than male patients on 3 of 8 subscales.

CONCLUSIONS

Three years after CABG the HRQOL is comparable to the general Norwegian population even in older patients. The older patients reported less pain than the general population.

Is the MacNew quality of life questionnaire a useful diagnostic and evaluation instrument for cardiac rehabilitation?

Purpose

The MacNew health-related quality of life questionnaire is internationally used as a standard for psychosocial assessment in many cardiac rehabilitation centres. This study investigates its discriminating capacity between diagnostic disease categories, sex and age at entry (T1) and at the end (T2) of cardiac rehabilitation as well as the responsiveness of the MacNew during this period.

Method

Data were used from 6749 cardiac rehabilitation patients at T1 and 1654 at T2.

Results

Results show that the global MacNew as well as the three (physical, emotional, social) subscales have high internal consistencies, and differentiate well and in the expected direction at T1 between diagnostic groups (heart surgery, myocardial infarction with and without percutaneous coronary intervention, stable angina with and without percutaneous coronary intervention, implantable cardioverter defibrillator, and heart failure patients), sex and age. The MacNew also proves to be an adequate evaluation instrument for cardiac rehabilitation, as all scales are responsive enough to capture changes from T1 to T2. At T2, however, the MacNew seems to lose some of its discriminating power, partly because of ceiling effects.

Conclusion

It is suggested to complement the use of the MacNew both at T1 and T2 with a brief anxiety and depression measure, which is valid and responsive for different groups of cardiac rehabilitation patients.

Factors associated with health-related quality of life in patients and significant others one month after coronary artery bypass grafting

AIM

To describe and compare the health-related quality of life of patients and their significant others and to identify factors associated with health-related quality of life one month after coronary artery bypass surgery.

BACKGROUND

Heart disease and coronary artery bypass surgery affect the life of patients and their significant others. Following surgery, some patients might feel their quality of life is poor. Significant others are a major source of support for patients; therefore, it is important to know how their health-related quality of life is affected.

METHODS

This study is part of a major longitudinal research project. The questionnaire data for the study were collected one month after the surgical procedure from 270 patients and 240 significant others at one Finnish university hospital. Data analysis was by descriptive and inferential statistics. Stepwise linear regression analysis was used as a multivariate method.

RESULTS

Coronary artery bypass grafting patients had a poorer health-related quality of life than both the age and gender-standardised general population and their significant others. Significant others, on the other hand, had the same health-related quality of life as the general population. In patients, health-related quality of life was associated with the occurrence of cardiac symptoms and New York Heart Association class; in significant others, it was explained by chronic illnesses, employment, gender and emotional support received from members of the support network.

CONCLUSION

In the early stages of recovery, the health-related quality of life of coronary artery bypass grafting patients is inferior to that of the general population. There are also differences in the health-related quality of life of patients and their significant others.

RELEVANCE TO CLINICAL PRACTICE

Postcoronary artery bypass grafting rehabilitation programmes should provide support for both patients and significant others through networks that involve both professionals and peer supporters.

Coronary Artery Bypass Grafting: Patients' and Health Professionals' Views of Recovery After Hospital Discharge

Background: Coronary artery bypass grafting (CABG) is effective in relieving symptoms and reducing mortality but some patients report no improvement or a decline in quality of life and hence do not experience a good recovery after surgery. Little published research has explored patients' and particularly health professionals' views on barriers and facilitators to recovery or the processes by which these factors affect recovery.

Aims: To identify post-discharge facilitators and barriers to recovery after CABG.

Methods: Semi-structured interviews were conducted with 11 patients who had previously undergone elective, isolated, first-time CABG and with 10 health professionals experienced in caring for these patients.

Results: Thematic analysis identified the following themes: person characteristics, including the impact on recovery of anxiety, depression, optimism and determination; rehabilitation classes; social support; and the effect of surgery. Findings indicate a complex relationship between the various barriers and facilitators to recovery and explore possible processes by which these influences on recovery operate.

Conclusions: Findings have indicated areas where health professionals can intervene to aid patients' long-term recovery, and thereby maximise the benefits of CABG, by providing information, support and reassurance particularly to patients who appear anxious and/or depressed.

The effect of preoperative uncertainty and anxiety on short-term recovery after elective arthroplasty

AIMS AND OBJECTIVES

This study examined the effect of preoperative anxiety and uncertainty on short-term physical and mental recovery after elective arthroplasty.

BACKGROUND

Uncertainty and anxiety accompany all medical procedures. Although preoperative uncertainty plays a central role in the development of stress, only a few studies explicitly examine this issue in terms of its impact on postoperative recovery.

DESIGN

Quazi-experimental study.

METHODS

Two self-administered questionnaires were used to collect data, before and five to six days after surgery. Participants (n = 87) admitted for elective arthroplasty completed the study.

RESULTS

Preoperative anxiety negatively affected postoperative recovery variables and preoperative uncertainty negatively affected mental and physical recovery after surgery. Furthermore, postoperative symptoms were related to the patients' subjective readiness to be discharged.

CONCLUSIONS

Separately, reduction of preoperative anxiety and uncertainty could have a positive impact on postoperative recovery and on perceived readiness to be discharged.

RELEVANCE TO CLINICAL PRACTICE

The unique contribution of each preoperative variable (uncertainty and anxiety) to postoperative recovery emphasizes the need for clinical and educational interventions that separately relieve uncertainty and anxiety.

The ICD shock and stress management program: a randomized trial of psychosocial treatment to optimize quality of life in ICD patients

BACKGROUND

Implantable cardioverter defibrillator (ICD) patients potentially face significant psychological distress because of their risk for life-threatening arrhythmias and the occurrence of ICD shock.

METHODS

The purpose of this study was to test an ICD stress and shock management program delivered in either a six-week format or a one-day workshop format. This intervention was aimed at reducing psychological (anxiety) and physiological (salivary cortisol) markers of distress in ICD patients. Secondary endpoints included measures of quality of life (QOL) and patient acceptance of device therapy, as well as biological mediators of inflammation (TNFalpha and IL-6).

RESULTS

The ICD stress and shock management program resulted in the reduction of anxiety (P < 0.05) and cortisol levels (P < 0.05) in both the six weekly sessions format and the one-day workshop. Measures of anxiety decreased more rapidly with weekly intervention (P = 0.05). Both formats also resulted in a significant increase in patient acceptance of the ICD (P < 0.01). Follow-up assessment from posttreatment (T2) to four-month follow-up (T4) indicated no significant change in depression scores from posttreatment for all groups taken together, but there was a significant group by time effect, such that the workshop group displayed an increase in depression scores from T2 (M = 8.71, SD = 4.39) to T4 (M = 13.57, SD = 11.90), P < 0.05.

CONCLUSIONS

These results suggest that structured interventions for shocked ICD patients involving ICD education and cognitive-behavioral strategies can reduce psychological distress and improve quality of life, regardless of format.

Stressors and Anxiety in Patients Undergoing Coronary Artery Bypass Surgery

Background Patients undergoing coronary artery bypass surgery who have increased anxiety levels have poorer outcomes than patients with lower levels, yet few studies have identified the concerns associated with this anxiety.

Objective To describe the concerns of patients undergoing coronary artery bypass surgery and to identify concerns that were associated with higher levels of anxiety.

Method Patients (n = 172) were interviewed to determine their concerns and anxiety levels before surgery, before discharge, and 10 days after discharge. Multiple regression was used to determine the predictors of anxiety.

Results Although individual concerns changed over time, anxiety levels did not change from before to after surgery, remaining low to moderate. Being female and having more concerns about waiting for the surgery, being in pain/discomfort, and resuming lifestyle were predictors of increased anxiety before surgery. Predictors of increased anxiety while hospitalized after the surgery included taking anxiolytic or antidepressant medications, higher anxiety levels before surgery, concerns about personal things being inaccessible, and difficulty sleeping. Patients with higher anxiety levels after discharge were older, more anxious before surgery, and had concerns about being in pain/discomfort.

Conclusion Patients waiting for coronary artery bypass surgery should be routinely assessed for anxiety before the procedure, and interventions to prevent or reduce anxiety should be provided. Interventions must be multifactorial, including information and support for pain management and realistic information about surgery schedules and resuming lifestyle after the surgery. Women and older patients may need to be targeted for intervention.

Protein S100B after cardiac surgery: an indicator of long-term anxiety?

OBJECTIVES

The aim of the study was to assess long-term state and trait anxiety in cardiac surgical risk patients.

DESIGN

Thirty two patients with serum S100B>0.3 microg/l 48 hours after cardiac surgery with cardiopulmonary bypass were matched according to age, gender, type, date and length of surgery with 35 operated patients without elevated S100B. They completed Spielberger's Anxiety Inventory (STAI).

RESULTS

Patients with elevated S100B reported more state anxiety and trait anxiety. S100B was an independent predictor of both state and trait anxiety when controlling for perioperative variables.

CONCLUSIONS

Patients with elevated S100B reported more anxiety 3-6 years after cardiac surgery. A postoperative blood sample can identify risk patients and facilitate appropriate follow-up.

Video information combined with individualized information sessions: Effects upon emotional well-being following coronary artery bypass surgery--A randomized trial

OBJECTIVE

To test the efficacy of an information intervention upon emotional recovery following coronary artery bypass surgery.

METHODS

Randomized trial. Video information was combined with individualized information sessions carried out by nurses at admission and at discharge from the hospital. The video was shown pre-operatively and again during the session at admission. Patients were helped to express their questions and worries and congruent information and support was provided. Control group patients received standardized information and no video. Recordings were made at baseline, discharge from hospital and during a 2 years follow-up period.

RESULTS

One hundred and nine patients were randomized to the intervention or the control groups. A MANOVA was used to test of the variance of the outcome variables at each time point. At discharge intervention patients reported less anxiety (p = 0.046) and better subjective health (p = 0.005). They reported better subjective health during the whole follow-up period (0.040 > or = p > or = 0.000), less anxiety up to 1 year (0.042 > or = p > or = 0.004), and less depression from 6 months to 2 years following discharge (0.023 > or = p > or = 0.004).

CONCLUSION

The effects of the intervention probably relate to the combined use of the video and patient centered information sessions.

PRACTICE IMPLICATIONS

The intervention can easily be implemented in clinical practice and nurses strongly identified with its principles.

Health related quality of life trajectories and predictors following coronary artery bypass surgery

BACKGROUND

Many studies have demonstrated that health related quality of life (HRQoL) improves, on average, after coronary artery bypass graft surgery (CABGS). However, this average improvement may not be realized for all patients, and it is possible that there are two or more distinctive groups with different, possibly non-linear, trajectories of change over time. Furthermore, little is known about the predictors that are associated with these possible HRQoL trajectories after CABGS.

METHODS

182 patients listed for elective CABGS at The Royal Melbourne Hospital completed a postal battery of questionnaires which included the Short-Form-36 (SF-36), Profile of Mood States (POMS) and the Everyday Functioning Questionnaire (EFQ). These data were collected on average a month before surgery, and at two months and six months after surgery. Socio-demographic and medical characteristics prior to surgery, as well as surgical and post-surgical complications and symptoms were also assessed. Growth curve and growth mixture modelling were used to identify trajectories of HRQoL.

RESULTS

For both the physical component summary scale (PCS) and the mental component summary scale (MCS) of the SF-36, two groups of patients with distinct trajectories of HRQoL following surgery could be identified (improvers and non-improvers). A series of logistic regression analyses identified different predictors of group membership for PCS and MCS trajectories. For the PCS the most significant predictors of non-improver membership were lower scores on POMS vigor-activity and higher New York Heart Association dyspnoea class; for the MCS the most significant predictors of non-improver membership were higher scores on POMS depression-dejection and manual occupation.

CONCLUSION

It is incorrect to assume that HRQoL will improve in a linear fashion for all patients following CABGS. Nor was there support for a single response trajectory. It is important to identify characteristics of each patient, and those post-operative symptoms that could be possible targets for intervention to improve HRQoL outcomes.

Does who you marry matter for your health? Influence of patients' and spouses' personality on their partners' psychological well-being following coronary artery bypass surgery

Research suggests that presurgical personality attributes influence postsurgical well-being in both patients and their spouses in the context of coronary artery bypass grafting (CABG) surgery. The authors hypothesized that a spouse's characteristics would influence a partner's psychological well-being, regardless of whether he or she was the patient or the caregiver. In this study, 111 male patients and their caregiver spouses completed measures of neuroticism, optimism, perceived marital satisfaction, and depression prior to elective CABG. Follow-up was conducted at 18 months. As expected, higher caregiver presurgical neuroticism predicted higher patient depressive symptoms at follow-up, with caregiver's concurrent 18-month affect controlled for. Likewise, higher patient presurgical neuroticism predicted higher caregiver depressive symptoms at follow-up. Additionally, higher patient presurgical depressive symptoms and lower presurgical optimism contributed to greater caregiving burden. Relationship satisfaction moderated these effects. These results suggest that partners' personality traits are important determinants of both patients' and their caregiving spouses' well-being.
