Denial: predictor of outcome following coronary bypass surgery

Cardiac Denial and Expectations Associated With Depression in Adults With Congenital Heart Disease

Depression in adults with congenital heart disease is highly prevalent and strongly associated with adverse prognosis. Better management of risk factors for depression may improve clinical outcomes in this population. We conducted a single-site, cross-sectional study of 78 adults with congenital heart disease followed at Washington University School of Medicine. Data considered in the analyses included retrospectively obtained clinical information and patients' self-assessed psychosocial functioning and health status. To identify the clinical and psychosocial variables associated with depression, we built a stepwise multivariate model to measure the relative contribution of these variables to depression status. The prevalence of depression in our sample was 26%. Our model accounted for approximately 67% of the variability in depression scores. The final model consisted of the Cardiac Denial of Impact Scale, expectations domain of Barriers to Care, and the energy and social domains of the Rand 36-Item Short Form Health Survey. Clinical variables did not predict variability in depression scores. In conclusion, greater cardiac denial and negative expectations of the healthcare team were associated with increased depression symptoms in ACHD.

Clinical and Psychological Drivers of Perceived Health Status in Adults With Congenital Heart Disease

The factors having the greatest impact on self-reported health status in adults with congenital heart disease (ACHD) remain incompletely studied. We conducted a single-site, cross-sectional study of ACHD patients followed at the Center for ACHD at Washington University School of Medicine, including retrospectively gathered clinical data and psychometric and health status assessments completed at the time of enrollment. To identify primary drivers of perceived health status, we investigated the impact of the demographic, clinical, and psychological variables on self-reported health status as assessed using the Rand 36-Item Short Form Health Survey. Variables with significant associations within each domain were considered jointly in multivariable models constructed via stepwise selection. There was domain-specific heterogeneity in the variables having the greatest effect on self-reported health status. Depression was responsible for the greatest amount of variability in health status in all domains except physical functioning. In the physical functioning domain, depression remained responsible for 5% of total variability, the third most significant variable in the model. In every domain, depression more strongly influenced health status than did any cardiac-specific variable. In conclusion, depression was responsible for a significant amount of heterogeneity in all domains of self-perceived health status. Psychological variables were better predictors of health status than clinical variables.

Cardiac Denial and Psychological Predictors of Cardiac Care Adherence in Adults With Congenital Heart Disease

The current study examined cardiac denial and psychological predictors (i.e., depression, anxiety) of health outcomes including medical nonadherence and physical health in a sample of 80 adults with congenital heart disease (ACHD). Results indicated that denial of impact was elevated in this patient group compared with reference groups, and denial was negatively associated with depression and anxiety at ps < .01. Results indicated that depression, anxiety, and denial predicted unique variance in medical nonadherence, and gender moderated the relationships between these psychological factors and nonadherence. For depression, men and women showed similar relationships between depression and nonadherence at high levels of depression; however, at low levels of depression (i.e., a more normal mood state), men were less adherent compared with women. For anxiety, men and women did not differ in adherence at low levels of anxiety; however, men experiencing high anxiety were less adherent compared with women experiencing high anxiety. Implications of this study are discussed including the role of gender and denial and the impact of denial functioning to reduce negative affect. Depression was the only significant predictor of physical functioning. Results of this study suggest that psychological interventions aimed at depression and anxiety may function differently across gender to improve patient medical adherence and improve physical functioning in ACHD.

Denial Defense Mechanism in Dialyzed Patients

BACKGROUND

It is a struggle to identify the most adaptive coping strategies with disease-mediated stress. Here, we hypothesize that intensity of coping strategies, including denial, in patients with end-stage renal disease (ESRD), varies with type of renal replacement therapy (RRT).

MATERIAL AND METHODS

We enrolled 60 in-center hemodialyzed patients (HD) and 55 patients treated with continuous ambulatory peritoneal dialysis (CAPD). We administered the Coping Inventory with Stressful Situation, Profile of Mood States, and Stroop Anxiety Inventory to measure patient coping strategies in the context of their ESRD. Denial defense mechanism was measured via the IBS-R/ED. The Nottingham Health Profile was used to evaluate self-perceived quality of life. Serum potassium, urea, creatinine, phosphorus, calcium, albumin, and hematocrit were utilized as the measurements of adequacy of dialysis.

RESULTS

HD patients had higher self-reported intensity of denial mechanism and avoidance-oriented strategies versus CAPD patients. Because a single strategy is almost never employed, we conducted cluster analysis. We identify 3 patterns of coping strategies using cluster analysis. "Repressors" employed denial and avoidance strategies and were predominant in HD. The second cluster consists of subjects employing predominantly task-oriented strategies with equal distribution among dialyzed patients. The third cluster encompassed a small group of patients who shared higher intensity of both denial and task-oriented strategies. Health-related outcome, anxiety, and mood profile were similar across all patients.

CONCLUSIONS

HD patients predominantly used "repressive" strategies. Patients on RRT utilized denial and avoidance-based strategies to achieve satisfactory outcome in terms of perceived quality of life. We conclude that these coping mechanisms that were previously thought to be inferior are beneficial to patient compliance with RRT.

Predictors of perceived need for medical care in an inpatient rehabilitation unit: an update

Limited awareness of illness, or poor insight, has been associated with poor treatment outcomes and prognoses in both psychiatric and medical populations. We examined predictors of insight in a sample of 403 patients in an inpatient rehabilitation unit at a Midwest Veterans Affairs Medical Center. A multiple regression analysis revealed that age, depression, IQ, and a measure of judgment were significant predictors of acknowledgement of illness. Younger age, higher IQ, better judgment, and depression were associated with better insight. By identifying risk factors for poor insight, these findings have significant clinical implications for healthcare providers.

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.

Which factors predict the persistence of DSM-IV depression, anxiety, and somatoform disorders in the medically ill three months post hospital discharge?

OBJECTIVE

This study sought to assess the persistence of DSM-IV depression, anxiety, and somatoform disorders in a sample of 206 medical patients 3 months after hospital discharge and to examine which baseline factors predicted the persistence of disorder.

METHODS

Patients were interviewed using the Monash Interview for Liaison Psychiatry (a structured psychiatric interview for the medically ill) during admission and again at 3 months post discharge. Scales completed during admission elicited sociodemographic data, psychiatric history, mental and physical functioning, illness behavior, coping modes, and number of close relationships. Best-subset logistic regression was employed to find the best combination of these potential predictors of the persistence of psychiatric disorder.

RESULTS

Persistence of anxiety disorders [n=43; 50.6%; 95% CI=39.5-61.6], depression (n=55; 44.4%; 95% CI=35.4-53.5), and somatoform disorders (n=35; 42.2%; 95% CI=31.3-53.0) was moderately high, with no statistically significant difference in the rate of persistence of the three groups of disorder. Family psychiatric history, education, and poorer physical and mental functioning during hospitalization predicted persistence of depression. Poorer mental functioning, less denial, and greater number of close relationships predicted persistence of anxiety disorders. Higher levels of education, use of acceptance-resignation as a coping mechanism, and greater hypochondriasis predicted persistence of somatoform disorders.

CONCLUSION

The belief that psychiatric disorders in hospitalized medically ill patients spontaneously remit after discharge is false. A substantial proportion persist for at least 3 months. Early detection and treatment is possible and warranted. Features of the illness (poorer physical and mental health) and personal and social factors identifiable at hospital admission identify patients at risk for persistence.

Denial of Chronic Illness and Disability: Part II. Research Findings, Measurement Considerations, and Clinical Aspects

The concept of denial has been an integral part of the psychological and disability studies bodies of literature for over 100 years.Yet, denial is a highly elusive concept and has been associated with mixed, indeed conflicting theoretical perspectives, clinical strategies, and empirical findings. In part II the author reviews empirical findings, measurement strategies, and clinical approaches associated with denial, with particular emphasis on rehabilitation-specific findings and implications. It focuses on empirical findings linking the use of denial to a number of psychosocial outcomes, measures that have been employed in the assessment of denial and, intervention strategies to manage denial. Part II concludes with a brief discussion of the implications generated by the current understanding of denial to rehabilitation practitioners and researchers.

Longitudinal Risk Factors for Adverse Psychological Functioning Six Months after Coronary Artery Bypass Graft Surgery

This research aimed to identify modifiable risk factors for poor psychological functioning six months post-operatively, using a chronic illness model to explain the relationships between risk factors. Consecutive elective CABG patients ( N = 119) completed self-report measures including optimism, illness representations, self-rated health, social support, coping methods, depression, anxiety and PTSD symptomatology in a repeated measures design. Poor pre-operative psychological functioning was the strongest psychological risk factor for adverse psychological functioning six months post-operatively. Longitudinal support for the chronic illness model examined was limited. Further research to identify modifiable risk factors and pre-operative psychopathology screening to determine individuals at-risk of poor psychological outcome is recommended.

Depression and anxiety and outcomes of coronary artery bypass surgery

Psychological and psychiatric disorders independently increase the risk of cardiovascular disease and worsen the prognosis in patients with established cardiovascular lesions. The objective of this literature review is to discuss recent data concerning the relationships between depression and anxiety and the outcomes of coronary artery bypass grafting. Pathophysiological hypotheses are put forward to explain observed links. We suggest recommendations aimed at improving the psychological evaluation and management of heart surgery candidates, as well as postbypass patients, in the hope of improving quality of life and cardiovascular outcomes in these patients.

Denial: a conceptual analysis

The term denial is used in nursing to describe a client's behavior. A random sample of 18 articles published in English from 1990 to 1999 was identified for conceptual analysis using Rogers' methodology. The 2 main definitions identified ranged from an adaptive to maladaptive coping process. Anxiety or perceived threats evolving from situational or maturational crises were antecedents. Events that followed typically resulted in either positive or negative outcomes. Related concepts used most often were avoidance, unrealistic hopefulness, and repression.

Depressive symptomatology in coronary artery bypass graft surgery patients

Depression is commonly reported in coronary artery bypass graft (CABG) surgery patients. This study assesses the relationship of preoperative characteristics, life stressors, social support, major cardiac and neurologic outcomes and other complications to depressive symptomatology. Demographic and clinical data, CES-D score and information on life stressors and social support were collected from 237 patients; 92% completed 6-month follow-up. CES-D score > or = 16 was defined as significant depressive symptomatology. Significant depressive symptomatology was found in 43% of patients preoperatively and 23% postoperatively. In multivariate models, low social support (p = 0.008), presence of at least one life stressor within a year of surgery (p = 0.006), moderate to severe dyspnea (p = 0.003), little to no available help (p = 0.05) and less education (p = 0.05) were associated with higher preoperative CES-D score, while longer intensive care unit (ICU) stay (p = 0.0001) and little or no available help (p = 0.0008) predicted higher postoperative CES-D scores when controlling for preoperative CES-D scores. Neither pre- nor postoperative depressive symptomatology was related to major outcomes or other complications. A high rate of significant depressive symptomatology exists in CABG patients preoperatively, and it decreases significantly postoperatively. Patients with the above preoperative characteristics as well as those who stay in the ICU postoperatively for more than 2 days might benefit from psychosocial interventions.

Determinants of an impaired quality of life five years after coronary artery bypass surgery

OBJECTIVE

To identify determinants of an inferior quality of life (QoL) five years after coronary artery bypass grafting (CABG).

SETTING

University hospital.

PARTICIPANTS

Patients from western Sweden who underwent CABG between 1988 and 1991.

MAIN OUTCOME MEASURES

Questionnaires for evaluating QoL before CABG and five years after operation. Three different instruments were used: the Nottingham health profile (NHP), the psychological general wellbeing index (PGWI), and the physical activity score (PAS).

RESULTS

2121 patients underwent CABG, of whom 310 died during five years' follow up. Information on QoL after five years was available in 1431 survivors (79%). There were three independent predictors for an inferior QoL with all three instruments: female sex, a history of diabetes mellitus, and a history of chronic obstructive pulmonary disease. Multivariate analysis showed that a poor preoperative QoL was a strong independent predictor for an impaired QoL five years after CABG. An impaired QoL was also predicted by previous disease.

CONCLUSIONS

Female sex, an impaired QoL before surgery, and other diseases such as diabetes mellitus are independent predictors for an impaired QoL after CABG in survivors five years after operation.

The course of anxiety and depression in patients undergoing coronary artery bypass graft surgery

A semilongitudinal study was designed to follow-up the course of anxiety and depression in patients undergoing coronary artery bypass graft (CABG) surgery. The focus was on possible effects of gender and age on variations in both mean level and interindividual differences over time. At two timepoints before and two after surgery, 217 patients completed self-report questionnaires. Multivariate testing revealed an overall decrease in mean levels of anxiety and depression in the postoperative period but different trends for men and women. Compared with men, women reported more anxiety and depression, both pre- and postoperatively, but showed a relatively stronger decrease in the early postoperative period. Regarding variations in interindividual differences over time, multivariate testing revealed different trends of depression for men and women. Women appeared to be most homogeneous in the early days after surgery, whereas interindividual differences for men showed a stable trend.

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

OBJECTIVE

To review studies predicting psychosocial outcome after coronary artery bypass graft surgery (CABG).

METHODS

Seventeen prospective studies, appearing in the MEDLINE and PsycLIT data bases between 1986 and 1996, were reviewed regarding objectives, methodological issues, results, and clinical relevance.

RESULTS

All studies reported that psychological factors bad predictive value. In particular, preoperative anxiety and depression predicted postoperative psychological maladjustment; social support, preoperative feelings of control, denial, and optimism contributed to psychological adjustment.

CONCLUSIONS

Many specific psychological outcomes seem to be best predicted by preoperative assessment of functions in that specific area, especially in the case of anxiety and depression. Furthermore, personality factors including denial, optimism, control, and the need for support appear to be predictors of psychological outcome. Appropriate identification of predictive factors might improve the development of individually tailored interventions for patients at risk of postoperative psychological problems.

Uncovering and managing denial during the research process

This article describes experiences of geropsychiatric nurses examining the effectiveness of the Progressively Lowered Stress Threshold Model for caregivers of persons with Alzheimer's disease and related disorders, and briefly reviews the literature on coping and denial. This research project, and those of many other psychiatric nurses, is predicated on the expectation that subjects will be able to acknowledge and report to investigators their personal and intimate responses to the challenges and everyday experiences of caregiving. Clearly, the research findings will be most valid if subjects are completely open about all aspects of their experiences, no matter how painful; yet this is often an idealized expectation. Therefore, this article also explores the concerns of geropsychiatric nurse researchers attempting to balance sensitivity to the needs of subjects and the reliability and validity of the data.

Psychosocial functioning of young adults after surgical correction for congenital heart disease in childhood: a follow-up study

To investigate the long-term psychosocial outcome of congenital heart disease, the emotional, intellectual and social functioning of 288 (young) adult patients was assessed with standardized assessment procedures 9-23 years (mean follow-up interval: 16 years) after surgical correction for congenital heart disease in childhood, and compared with that of reference groups. With respect to emotional functioning, the patients reported significantly fewer feelings of hostility, fewer neurotic complaints and a better self-esteem than reference subjects. Overall, the results concerning social functioning showed favourable outcomes on daily activities (school, employment) and leisure-time activities for (young) adults with congenital heart disease. No significant differences were found between scores of different cardiac diagnostic groups on hostility, neuroticism, self-esteem and leisure-time activities. The possibility whether the 'denial'-mechanism might have contributed to the positive outcomes is discussed.

The Alcoholism Denial Assessment Tool (ADAT): a study of interrater reliability

The purpose of this study was to develop and test a tool for assessing alcoholic denial. The primary author devised the Alcoholism Denial Assessment Tool (ADAT) based on 2 years of experience. The tool was tested for interrater reliability using chart data of 42 recently discharged alcoholism patients. The test for significance of a proportion, using z scores, indicated significance at the .001 level. Item analysis showed strong interrater reliability on all but 1 of the 16 tool items. The ADAT provides nurses with a practical assessment tool that can be used daily to monitor progress. Recognition that a patient is in denial can allow meaningful and appropriately planned treatment.

The cardiac denial of impact scale: a brief, self-report research measure

Denial is an important aspect of recovery from cardiac trauma. It has been associated with reduced anxiety, better initial physical and psychological outcomes, decreased retention of information about the illness, and decreased treatment compliance. Although interview methods for assessing denial have been available for some time, they present both psychometric and methodological difficulties that a self-report measure could alleviate. This study provides the initial psychometric evaluation of the self-report Cardiac Denial of Impact Scale. It demonstrated adequate internal consistency as well as good criterion and discriminant validity. The availability of a self-report measure of denial can simplify its assessment in both research and treatment applications.

Examining the process and dilemmas of reality negotiation

Reality negotiation is the process people use to examine information from their environment and make judgments about the accuracy and importance of that information. Although this process has been found to be inaccurate, nurses often express discomfort when clients hold perceptions of reality that run counter to their own views. Nurses in these circumstances see the client as denying or as having unrealistic hopes. This article examines reality negotiation in light of this clinical dilemma, focusing on three areas: 1) the assumptions made regarding the nature of reality; 2) the potential and real outcomes of different types of reality negotiation; and 3) the process by which reality is redefined and how unrealistic perceptions are threatened and/or abandoned. These issues are explored as they relate to nursing research and practice.
