Patient-perceived quality of life after coronary bypass surgery. Experienced problems and reactions to supportive care one year after the operation

In an interview conducted one year after coronary bypass surgery (CABG), 115 patients (92 males, 23 females) were asked to discuss their present quality of life, problems related to the operation and their reactions to the supportive care following the operation. The main purpose of this study was to assess whether the patients' own presentation of these questions revealed information not elucidated through a standard questionnaire which included the Nottingham Health Profile and other questions on physical, emotional and social well-being. About one quarter of the interviewed patients expressed dissatisfaction concerning their present quality of life, information which corresponded well with the findings in the questionnaires. Reported limitation in physical activity did not, however, match exercise test findings. The interviews alone revealed additional information concerning well-being. Most important were problems with wound healing and difficulties describing and interpreting pain and other discomfort in the thoracic area. Several patients also expressed dissatisfaction with the postoperative supportive care. We conclude that there is a need for a complementary approach to estimate quality of life, and that this could be included in an extended nursing care program designed to meet the varying needs of patients after CABG.

Patients' fears in coronary arteriography

This study was concerned with the objects of fear and the intensity of fears related to coronary arteriography (CA) in 378 patients scheduled for coronary arteriography at a university hospital. Intensity of fear was measured on a 10-point Likert-type scale which listed 26 objects of fear. The patients were asked to assess the intensity of their fears both before and after CA. The results showed that the intensity of fear varied depending upon the object of fear. The highest intensity was recorded for fear of coronary artery bypass surgery. A significant increase was found in fear of lying flat in bed after CA and fear of not receiving social support. Fears of uncertainty about the illness, the CA procedure, results of CA, pain, coronary artery bypass surgery and coronary angioplasty decreased significantly after CA. Significant associations were found between objects of fear and patient demographics. It is concluded that patients' fears should be assessed individually both before and after CA. Special attention should be paid to the fears of women, patients under 45 years, upper and lower level employees and the unemployed.

Coronary artery bypass grafting: long-term psychological and social outcomes

Long-term psychosocial outcomes were examined in 132 patients 7 to 22 years (M = 9.4 years) after coronary artery bypass grafting. The control group comprised 145 medically treated patients with coronary heart disease of 7 to 22 year duration (M = 9.2). Significantly more medically than surgically treated patients were scored in the clinically significant range for anxiety, and for depression on the hospital anxiety and depression scale. Significantly more medically than surgically treated patients reported a definite, considerable, or very severe impairment of family relationships, social activities, leisure activities, home management, and work on the social functioning scale. Work status did not significantly differ between surgical and medical patients. This study shows previously unreported long-term favorable psychosocial outcomes in patients who underwent coronary artery bypass grafting.

Social comparisons and temporal comparisons after coronary artery surgery

OBJECTIVE

To examine the use and efficacy of social and temporal comparisons used before and after coronary artery surgery.

DESIGN

Secondary analysis of data from a prospective study designed to examine social support.

PATIENTS

141 subjects undergoing surgery.

RESULTS

One third of subjects made spontaneous social comparisons. Most who made a social comparison before and 1 month after surgery viewed themselves as similar to others. Social comparisons were related to mood states only before surgery. The majority of subjects made temporal comparisons 1 year after surgery. Subjects generally saw themselves as the same or better than they were before surgery. Temporal comparisons were related to both emotional and functional outcomes.

CONCLUSIONS

Social comparisons were not consistently related to emotional and functional status; thus whether they can be used to formulate interventions needs further exploration. On the other hand, use of temporal comparisons was related to better mood state and functional status. Enhancing an individual's ability to view self as stable or improved compared with before surgery may be beneficial. Results are discussed in terms of how social comparison theory fits within the overall context of coping with physical illness.

Intensive rehabilitation of emotionally distressed patients after coronary by-pass grafting

OBJECTIVES

To evaluate whether the status of emotionally distressed post coronary by-pass surgery patients can be improved by a comprehensive, in-patient rehabilitation programme.

DESIGN

Cross-sectional.

SETTING

Rehabilitation hospital.

SUBJECTS

One hundred and fifty-two post coronary by-pass surgery patients referred to an intensive rehabilitation programme. The study group was divided into two subgroups, according to the level of emotional distress. Forty-three (30%) out of 142 patients who completed the Nottingham Health Profile were considered to be distressed.

INTERVENTIONS

The comprehensive 4-week inpatient rehabilitation programme consisted of daily physical exercise, lectures about coronary disease and risk factors, psychological support and nutrition counselling.

MAIN OUTCOME MEASURES

Physical fitness, blood lipids and quality of life questionnaires.

RESULTS

The two-way analysis of variance showed that emotionally distressed patients achieved equally good results as those obtained by nondistressed patients in performance regarding the maximal exercise stress test, maximum rate pressure product achieved, or the level of resting heart rate. Significant improvement in psychological well-being as assessed by a seven-point rating scale was observed in both groups. Both groups of patients were also equally successful in weight reduction and lowering of total cholesterol and triglycerides. Of all the patients who were employed at admission, twice the number of patients in the distressed group were in receipt of a permanent disability pension and half the number of patients was employed, compared to the initially nondistressed group, at 1-year follow-up.

CONCLUSIONS

Distressed patients were very successful in improving their functional status and reducing risk factors when offered an intensive rehabilitation programme but they were much less successful in returning to work. Secondly, patients who were emotionally distressed after surgery did not differ in regard to disease status or physical capacity from nondistressed patients. They did, however, experience more angina pectoris both in daily life and when exposed to a maximal exercise stress test. Finally, the presence of emotional distress was easily detected by any measure of psychological status.

Psychosocial adjustment and mental health two months after coronary artery bypass surgery: a multisystemic analysis of patients' resources

Resources related to cardiac patients' sense of self, marital quality, and social support were assessed before their first planned bypass surgery to determine their relationship with later psychosocial functioning. Six female and 45 male cardiac patients, 45-70 years old, answered self-report instruments 1 week before and 8-10 weeks after the operation. Regression analyses indicated that only the marital relationship variables made independent contributions to the prediction of functioning. Since self-report measures of resources can be affected by negative affectivity, a second level of analysis predicted change scores while controlling for initial levels of functioning. Marital flexibility and support were found to make an independent contribution to recovery. These results highlight the importance of marital resources in coping with the acute phase following bypass surgery and have implications for prevention and clinical practice.

Mutuality and preparedness of family caregivers for elderly women after bypass surgery

The purposes of this study were to identify caregivers' feelings of mutuality and reported preparedness for caregiving at hospital discharge and to examine the relationship between these measures and the recovery outcomes of elderly women after coronary artery bypass graft (CABG) surgery. A sample of 49 dyads was followed at discharge, 6 weeks, 3 months, and 6 months. The caregivers' Mutuality Scale (MS) scores and Preparedness for Caregiving (PCS) scores at discharge indicated positive feelings about the relationship with the elderly woman and their preparedness, and both measures were positively correlated with the self-report recovery measures at 3 months (p < .05). Nevertheless, at 3 months the MS scores were significantly lower than at discharge (p < .05), indicating stress in the caregiver-patient relationship. The MS and PCS may be useful tools for assessing situations and directing nursing interventions during discharge planning.

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.

The unique benefits of religious support during cardiac bypass surgery

Compares the self-reports of family members waiting during the cardiac artery grafting surgery of a loved one and explores whether they make distinctions between the contributions of nonreligious and religious support. Results from regression analyses suggests that the use of religious sources of support was associated with both more positive religious and nonreligious psychosocial adjustment scores after the influences of nonreligious support were statistically removed. Notes that among the 13 religious support activities identified, family members reported using prayer most frequently. Concludes that using religious support sources to cope with this surgically related stress is associated with distinct subjective benefits beyond those contributed by nonreligious sources.

Perception of cognitive function in older adults following coronary artery bypass surgery

This study examined the effects of coronary artery bypass grafting (CABG) on objective and subjective measures of neurocognitive functioning. Participants were 170 older patients (127 men and 43 women; mean age = 61 years) undergoing CABG. Measures of neurocognitive function, depression, anxiety, and perceived cognitive abilities were administered immediately prior to and 6 weeks following surgery. Although objective measures of impaired cognitive performance following CABG were not related to perceived cognitive difficulties, the presence of anxiety and depression was related to the perception of cognitive functioning. Patients who reported high levels of anxiety and depression 6 weeks after surgery perceived themselves as having poorer cognitive function. Interventions designed to reduce emotional distress could improve patient's perceived cognitive abilities following CABG.

Sleep and quality of life assessment in patients undergoing coronary artery bypass grafting

OBJECTIVE

To examine sleep before and after coronary artery bypass grafting (CABG) as well as measuring of quality of life (QoL), and to see if changes in subjectively rated sleep can be shown objectively by polysomnographic recordings.

SAMPLE

A consecutive sample of 38 male patients, aged 45-68, underwent CABG, Twenty-two patients were graded in New York Heart Association (NYHA) classes III or IV, and 16 in class I-II before surgery.

METHODS

24-hour polysomnographic recordings, using the Oxford Medilog 9000 recorder, were performed 2 days prior to surgery, on the first 2 post-operative days and 1 month after surgery. The Nottingham Health Profile instrument (NHP) was used to measure QoL before and after surgery.

RESULTS

Following surgery there was a profound decrease in sleep at night, and an increase in daytime sleep. During the second post-operative recording period nocturnal sleep duration was reduced to 253.6 +/- 94.1 minutes, with suppressed stages 3 and 4 sleep and lack, or slight recovery, of REM sleep. Even though there were evident changes in both the distribution and nature of sleep at night, daytime sleep increased and the total duration of sleep during the 24-hour period was not significantly changed. The total sleep time was 421.1 +/- 76.8 minutes before surgery, 483.2 +/- 201.2 in the first period, 433.2 +/-201.4 minutes in the second 24-hour period post-operatively and 443.2 +/- 44.0 minutes at the 1-month follow-up. The NHP instrument demonstrated that 6 months after surgery the quality of life was significantly improved. Polysomnographically measured slow wave sleep was compared with the sleep section in the NHP instrument both before surgery and at 1 month post-operatively.

CONCLUSIONS

In the immediate period following CABG, there is a change in distribution of sleep, with reduction in nocturnal sleep duration and an increase in daytime sleep, which had almost returned to pre-operative values 1 month after surgery. QoL scores were improved 6 months after surgery. This study demonstrates the importance of careful assessment of sleep and sleep disturbances for more individualized nursing care in order to promote sleep in the immediate post-operative period.

Implementation of a patient-family pathway: effects on patients and families

The purpose of this study was to discover whether implementation of a patient-family pathway with patients and families undergoing coronary artery bypass graft (CABG) surgery impacted anxiety, information with care planning, and patient length of stay. Using an experimental design, a sample of 60 patients and family members was studied. Each patient and his or her designated family member received either the patient-family pathway or the hospital's standard care planning. Findings indicated no statistically significant differences in state anxiety or information with care planning between patients and family members receiving the patient-family pathway and those receiving standard care planning. There was no statistically significant difference in length of stay between the two patient groups. The results indicate that the CABG patient-family pathway has limited value to patients and families as measured in this study. Resources can be real-located to other uses that may have a more positive impact on the patient and family experience.

The psychology of men and women recovering from coronary artery bypass surgery

BACKGROUND

Little is known about the differences between men's and women's cardiac rehabilitation processes. What helps men during recovery may not necessarily aid women's recovery. Psychosocial variables are known to impact recovery in positive and negative ways. Unfortunately, it is not clear what variables are the most effective predictors of recovery outcomes for men and women.

METHODS

Ninety coronary artery bypass graft patients (60 men, 30 women) completed a battery of psychological questionnaires on or after the third day after surgery.

RESULTS

Results showed that women reported significantly more depressive symptoms than men. For women, pain was correlated positively with depressive symptomatology and functional impairment. For men, pain and functional impairment were correlated negatively with social support. In addition, the results of a multiple regression of pain on age, severity of disease, and two psychosocial variables (depressive symptomatology and social support) for the women showed that after controlling for age and severity of disease, depressive symptomatology and social support accounted for a significant 43% increment in the variance in pain. The psychosocial variables accounted for much less variance in pain in men. However, in a multiple regression of functional impairment on the same variables, depressive symptomatology and social support accounted for a significant 14% increment in the variance in pain in men but a nonsignificant increment for the women.

CONCLUSIONS

The results support the notion that psychosocial variables play different roles in the recovery paths of men and women. In consequence, cardiac rehabilitation programs would be more effective with gender-specific tailoring.

Optimism and rehospitalization after coronary artery bypass graft surgery

OBJECTIVE

To determine whether optimism predicts lower rates of rehospitalization after coronary artery bypass graft surgery for the 6 months after surgery.

METHODS

A prospective, inception cohort design was used. The sample consisted of all consenting patients (N=309) from a consecutive series of patients scheduled for elective coronary artery bypass graft surgery at a large, metropolitan hospital in Pittsburgh, Pa. To be eligible, patients could not be scheduled for any other coincidental surgery (eg, valve replacement) and could not be in the cardiac intensive care unit or experiencing angina at the time of the referral. Participants were predominantly men (69.9%) and married (80.3%), and averaged 62.8 years of age. Recruitment occurred between January 1992 and January 1994.

RESULTS

Compared with pessimistic persons, optimistic persons were significantly less likely to be rehospitalized for a broad range of aggregated problems (including postsurgical sternal wound infection, angina, myocardial infarction, and the need for another bypass surgery or percutaneous transluminal coronary angioplasty) generally indicative of a poor response to the initial surgery (odds ratio=0.50, 95% confidence interval=0.33- 0.76; P=.001). The effect of optimism was independent of traditional sociodemographic and medical control variables, as well as independent of the effects of self-esteem, depression, and neuroticism. All-cause rehospitalization also tended to be less frequent for optimistic than for pessimistic persons (odds ratio=0.77, 95% confidence interval=0.57-1.05; P=.07).

CONCLUSIONS

Optimism predicts a lower rate of rehospitalization after coronary artery bypass graft surgery. Fostering positive expectations may promote better recovery.

In the queue for coronary artery bypass grafting: patients' perceptions of risk and 'maximal acceptable waiting time'

OBJECTIVES

To elicit patients' maximal acceptable waiting times (MAWT) for non-urgent coronary artery bypass grafting (CABG), and to determine if MAWT is related to prior expectations of waiting times, symptom burden, expected relief, or perceived risks of myocardial infarction while waiting.

METHODS

Seventy-two patients on an elective CABG waiting list chose between two hypothetical but plausible options: a 1-month wait with 2% risk of surgical mortality, and a 6-month wait with 1% risk of surgical mortality. Waiting time in the 6-month option was varied up if respondents chose the 6-month/lower risk option, and down if they chose the 1-month/higher risk option, until the MAWT switch point was reached. Patients also reported their expected waiting time, perceived risks of myocardial infarction while waiting, current function, expected functional improvement and the value of that improvement.

RESULTS

Only 17 (24%) patients chose the 6-month/1% risk option, while 55 (76%) chose the 1-month/2% risk option. The median MAWT was 2 months; scores ranged from 1 to 12 months (with two outliers). Many perceived high cumulative risks of myocardial infarction if waiting for 1 (upper quartile, > or = 1.45%) or 6 (upper quartile, > or = 10%) months. However, MAWT scores were related only to expected waiting time (r = 0.47; P < 0.0001).

CONCLUSIONS

Most patients reject waiting 6 months for elective CABG, even if offered along with a halving in surgical mortality (from 2% to 1%). Intolerance for further delay seems to be determined primarily by patients' attachment to their scheduled surgical dates. Many also have severely inflated perceptions of their risk of myocardial infarction in the queue. These results suggest a need for interventions to modify patients' inaccurate risk perceptions, particularly if a scheduled surgical date must be deferred.

[Phenomenon of preoperative stress in patients with ischemic heart disease. Assessment of its clinical and prognostic significance]

AIM

To assess preoperative stress in patients with ischemic heart disease (IHD) and its influence on the course of early intraoperative period.

MATERIALS AND METHODS

79 patients scheduled for aortocoronary bypass operation were studied to assess the phenomenon of preoperative psychoemotional stress (clinical characteristics, personal anxiety, humoral and vegetative regulation.

RESULTS

24 hours before operation IHD patients became anxious, coronary insufficiency and arrhythmia aggravated as shown by Holter ECG monitoring. Initial insufficiency of the antioxidant system, disturbances of the platelet-vascular hemostasis, hyperlipidemia and dyslipoproteinemia enhanced. Preoperative changes due to stress reaction affected the course of early intraoperative period.

CONCLUSION

It is necessary to apply individual schemes of stress-limiting preoperative preparation in IHD patients.

A structural modeling analysis of anxiety and depression in patients undergoing coronary artery bypass graft surgery: a model generating approach

The present study is a longitudinal study designed to explore structural relationships between anxiety, depression, personality, and background factors (e.g., gender, age, and complicated medical characteristics) in patients undergoing coronary artery bypass graft (CABG) surgery. At two timepoints before and two after CABG, 217 patients completed self-report questionnaires. To explore structural relationships, the structural equation modeling (SEM) method was applied. Using the model-generating approach, a model was developed, providing a good fit. The structural relationships revealed, in particular, the key position of neuroticism, which was related to both pre- and postoperative anxiety and depression. Relationships between anxiety and depression over time, both intra- and interrelationships, were relatively weak. Relationships between anxiety and depression at the same points in time were relatively strong, with preoperative depression leading to preoperative anxiety, and postoperative anxiety leading to postoperative depression. To provide a useful framework for development of intervention strategies, further research is needed to evaluate the plausibility of the final structural model.

Gender and willingness to undergo invasive cardiac procedures

To explore the role of patient preferences in explaining gender differences in the use of invasive cardiac procedures, we surveyed 174 patients presenting for cardiac stress testing at a university hospital. Controlling for sociodemographic factors, health status, symptom severity, and history of prior procedures, women expressed greater willingness than men to accept a physician's recommendation of cardiac catheterization (odds ratio 7.1; 95% confidence interval 1.1, 45.3) and similar willingness to accept a recommendation for coronary angioplasty or coronary artery bypass graft surgery. We conclude that patient preferences are unlikely to explain gender disparities in the use of invasive cardiac procedures.

Late neurocognitive changes from neurological damage following coronary bypass surgery

A detailed case study with neuropsychological data over a 26-year period was used to explore the relationship between neurocognitive vulnerability preoperatively and subsequent neurocognitive decline identified several years postoperatively. Guidelines regarding the importance of neuropsychological assessment of intelligence, attention, memory, language, and visual-spatial planning and organizational skills are provided. Such evaluations clarify postoperative treatment planning because rehabilitation of cardiac patients with premorbid neurocognitive deficits poses special rehabilitation problems. With a detailed neurologic history as part of the preoperative evaluation, healthcare providers can identify acute and subtle risk factors for postoperative neurologic syndromes. This may lead to interventions designed to provide increased patient and family support.

[Aortocoronary bypass: methods of group psychotherapy and instruction and the rehabilitation potentials]

In a large number of patients aortocoronary shunting often leads to persistent neurotic disorders' development. Taking into account the biological, psychological and social factors contributing to the disease pathogenesis, the authors tend to introduce some methods of active involvement of patients into a rehabilitation-prophylactic process to restore their mental health balance, behavioral standards, communicative habits etc.

Health resource utilization and quality of life outcomes of low-risk coronary artery bypass graft patients: a comparison study

Coronary artery bypass graft surgery (CABG), undertaken because of a decline in quality of life (QOL), is known to decrease morbidity and mortality, but it is expensive. At University Campus, London Health Science Centre, (UC-LHSC), a clinical path for CABG patients categorized as low-risk by UC-LHSC was developed to decrease the costs of CABG surgery through a shortened hospital stay while maintaining quality of patient care. The purpose of this research was to compare traditional care of the CABG patient with the care of those on the Clinical Path for Coronary Artery Bypass Graft Patients on health resource utilization (HRU) and QOL outcomes 6 to 12 months post surgical discharge. The results of this study showed that while the experimental group made significantly more emergency department visits than did the control group, the groups did not differ on the health resource utilization categories of extra office visits, home care, or hospital admission. It was also found that within the experimental (Clinical Path) group there were significantly fewer extra office or clinic visits required by the subjects who received the Preadmission Program than by the participants who did not receive this program. No differences were found in quality of life 6 months after CABG surgery between low-risk patients receiving traditional care and those patients on the CABG Clinical Path. Results of this study have increased understanding of the impact of a shorter hospital stay upon CABG patients and on the health care system.

The preparation of patients for cardiac surgery

This study examines the impact of a preadmission telephone intervention on anxiety, knowledge, and readiness for discharge for patients attending a preadmission teaching program prior to cardiac surgery. The primary goal of the telephone intervention was to provide support by giving additional information about individual concerns. The telephone intervention did not have an effect on anxiety and knowledge. A significantly higher level of anxiety was found in the experimental group on admission, but this difference became nonsignificant when baseline level and length of waiting time were entered as covariates. The more anxious group rated their perceived knowledge level lower, despite the fact that both groups had similar scores in actual knowledge. Given the potential barrier that anxiety can pose for patient learning, nurses need to adapt their interventions to deal with the patients' feelings of anxiety that accompany cardiac surgery to make the learning process effective.
