Presurgical depression predicts medical morbidity 6 months after coronary artery bypass graft surgery

Sex Differences in Delirium after Coronary Artery Bypass Graft Surgery and Perioperative Neuropsychiatric Conditions: A Secondary Analysis of a Cohort Study

BACKGROUND

Biological sex influences the risk of depression and cognitive impairment, but its role in relation to postoperative delirium is unclear. This analysis investigates sex differences in delirium risk after coronary artery bypass graft (CABG) surgery and sex-related differences in relation to affective and cognitive symptoms.

METHODS

This is a secondary analysis of the Neuropsychiatric Outcomes After Heart Surgery (NOAHS) study, a single-site, observational study of a CABG surgery cohort (n = 149). Preoperative characteristics are stratified by sex, and baseline variables that differ by sex are evaluated to understand whether sex modifies their relationships with delirium. We also evaluate sex differences in one-month depression and cognition.

RESULTS

Female sex is associated with several delirium risk factors, including higher risk of preoperative depression and middle cerebral artery (MCA) stenosis. MCA stenosis was statistically associated with delirium only among women (OR 15.6, 95% CI 1.5, 164.4); mild cognitive impairment (MCI) was associated with delirium only in men (OR 4.6, 95% CI 1.2, 17.9). Other sex-based differences failed to reach statistical significance. Depression remained commoner among women 1 month post-CABG.

CONCLUSIONS

Women in this CABG cohort were more likely to have depression at baseline and 1 month postoperatively, as well as MCA stenosis and postoperative delirium. Sex might modify the relationship between post-CABG delirium and its risk factors including MCA stenosis and MCI. Cerebrovascular disease deserves study as a potential explanation linking female sex and a range of poor outcomes among women with coronary heart disease.

The impact of pre-operative depression on pain outcomes after major surgery: a systematic review and meta-analysis

Symptoms of depression are common among patients before surgery. Depression may be associated with worse postoperative pain and other pain-related outcomes. This review aimed to characterise the impact of pre-operative depression on postoperative pain outcomes. We conducted a systematic review of observational studies that reported an association between pre-operative depression and pain outcomes after major surgery. Multilevel random effects meta-analyses were conducted to pool standardised mean differences and 95%CI for postoperative pain scores in patients with depression compared with those without depression, at different time intervals. A meta-analysis was performed for studies reporting change in pain scores from the pre-operative period to any time-point after surgery. Sixty studies (n = 501,962) were included in the overall review, of which 18 were eligible for meta-analysis. Pre-operative depression was associated with greater pain scores at < 72 h (standardised mean difference 0.97 (95%CI 0.37-1.56), p = 0.009, I2  = 41%; moderate certainty) and > 6 months (standardised mean difference 0.45 (95%CI 0.23-0.68), p < 0.001, I2  = 78%; low certainty) after surgery, but not at 3-6 months after surgery (standardised mean difference 0.54 (95%CI -0.06-1.15), p = 0.07, I2  = 83%; very low certainty). The change in pain scores from pre-operative baseline to 1-2 years after surgery was similar between patients with and without pre-operative depression (standardised mean difference 0.13 (95%CI -0.06-0.32), p = 0.15, I2  = 54%; very low certainty). Overall, pre-existing depression before surgery was associated with worse pain severity postoperatively. Our findings highlight the importance of incorporating psychological care into current postoperative pain management approaches in patients with depression.

Surgical healing beyond the scalpel: exploring the impact of depressive symptoms on functional recovery in total knee arthroplasty patients

BACKGROUND

Numerous recent studies have explored the association between the mental health condition of patients before surgery and the outcomes of total knee arthroplasty. The objective of this study was to determine the prevalence of depressive symptoms among individuals undergoing total knee arthroplasty and to investigate the impact of pre-operative depressive symptoms as a significant and independent predictor on various health-related quality of life measures for patients undergoing knee surgery.

MATERIAL AND METHODS

During the period spanning from August 2019 to May 2020, an orthopedic database was established for the purpose of assessing patients' conditions before their surgeries. The data collection process occurred at three distinct intervals: prior to the surgery, as well as at the third and sixth months following the surgical procedure. In this study, we undertook an evaluation of both pre-operative and postoperative depressive symptoms, as well as functional status, utilizing various self-report measures. These measures included the Becks Depression Scale, the Western Ontario and McMaster Universities Osteoarthritis Index, and the Knee Society Clinical Rating System.

RESULTS

A total of 150 patients were included in the study. The proportion of patients who were severely distressed decreased from 99% (149) at the baseline assessment to 76% (114) who had mild depression and 24% (36) at borderline at 3-months of follow-up. At 6-month follow-up period, 85% (128) patients were classified as normal, with 15% (22) displaying mild distress levels.

CONCLUSIONS

Patients experiencing depression exhibited notable enhancements in various outcome measures. The findings from this study underscore a two-way relationship between mental health and surgical outcomes. Specifically, the surgical intervention yielded significant improvements in mental health status. Conversely, poorer pre-operative mental health status emerged as a predictive factor for comparatively less favorable outcomes stemming from the surgery.

The moderating role of depressive symptoms in the association between heart rate variability and cognitive performance in cardiac patients

INTRODUCTION

Coronary heart disease (CHD) is strongly associated with cognitive impairment, which is a core feature of depression, highly prevalent in patients with CHD. Interestingly, patients with CHD and individuals with depression display reduced heart rate variability (HRV), which proxies a complex network integrating autonomic and attentional systems. This study investigated the moderating role of depressive symptoms in the relation between reduced HRV and cognitive performance in patients with CHD.

METHOD

The sample included 274 patients with CHD (mean [standard deviation] age = 62 [9.5] years; 13 % women) admitted to cardiac rehabilitation units. Visual attention and task switching were assessed through the Trail Making Test (TMT). Depressive symptoms were assessed with the Beck Depression Inventory-II (BDI-II). Resting electrocardiographic recordings were collected to compute HRV indices.

RESULTS

Patients with more severe depressive symptoms displayed an inverse association between HRV and cognitive performance (TMT-A: b = -0.08, p = .022; TMTB: b = -0.07, p = .042), whereas patients with milder depressive symptoms showed no significant association (TMT-A: b = -0.00, p = .90; TMTB: b = -0.02, p = .44).

CONCLUSIONS

Depressive symptoms may strengthen the relation between reduced HRV and poorer cognitive performance in cardiac patients. The presence of depressive symptoms may signal the dysfunction of a network subserving autonomic and cognitive function.

Hesperidin reduces serum levels of triglyceride after coronary artery bypass graft surgery

Hesperidin, as an antioxidant and anti-inflammatory agent, has beneficial effects on cardiovascular diseases. This study aimed to determine the effects of hesperidin supplementation on inflammation, oxidative stress, and lipid profile in depressed coronary artery bypass graft surgery (CABG) patients. Eighty patients after coronary artery bypass graft surgery participated in this clinical trial and were randomly divided into two groups. The intervention group received 200 mg/d pure hesperidin supplement and the second group received placebo for 12 weeks. Both groups continued their usual diet. Serum concentrations of inflammatory and stress oxidative markers (hs-CRP, P-selectin, and ox-LDL) were measured and compared at baseline and the end of the intervention. The changes in serum levels of triglyceride were significantly different between the two groups (p < .05). HDL-c significantly increased in groups but the differences between the two groups were not statistically significant (p > .05). Hesperidin did not affect FBS, other lipid parameters, hs-CRP, P-selectin, and OX-LDL (p > .05). SBP and DBP differences were not statistically significant (p > .05). After 12 weeks of intervention, hesperidin reduced serum levels of triglyceride in depressed post-CABG patients.

The pathophysiology and management of depression in cardiac surgery patients

Background

Depression is common in the cardiac surgery population. This contemporary narrative review aims to explore the main pathophysiological disturbances underpinning depression specifically within the cardiac surgery population. The common non-pharmacological and pharmacological management strategies used to manage depression within the cardiac surgery patient population are also explored.

Methods

A total of 1291 articles were identified through Ovid Medline and Embase. The findings from 39 studies were included for qualitative analysis in this narrative review.

Results

Depression is associated with several pathophysiological and behavioral factors which increase the likelihood of developing coronary heart disease which may ultimately require surgical intervention. The main pathophysiological factors contributing to depression are well characterized and include autonomic nervous system dysregulation, excessive inflammation and disruption of the hypothalamic-pituitary-adrenal axis. There are also several behavioral factors in depressed patients associated with the development of coronary heart disease including poor diet, insufficient exercise, poor compliance with medications and reduced adherence to cardiac rehabilitation. The common preventative and management modalities used for depression following cardiac surgery include preoperative and peri-operative education, cardiac rehabilitation, cognitive behavioral therapy, religion/prayer/spirituality, biobehavioral feedback, anti-depressant medications, and statins.

Conclusion

This contemporary review explores the pathophysiological mechanisms leading to depression following cardiac surgery and the current management modalities. Further studies on the preventative and management strategies for postoperative depression in the cardiac surgery patient population are warranted.

Functional, cognitive, and cerebrovascular aspects of depression before coronary artery bypass graft surgery: Testing the vascular depression hypothesis

OBJECTIVE

Depression in patients undergoing coronary artery graft bypass (CABG) surgery is associated with morbidity and mortality, making its early identification and clinical management crucial. Vasculopathy and older age, hallmarks of patients requiring CABG, are also features of vascular depression. In this study, we assess for features of vascular depression in patients undergoing CABG surgery.

METHODS

This is a cross-sectional analysis of a single-site prospective observational cohort study of patients undergoing CABG surgery. Subjects were assessed preoperatively using the Depression Interview and Structured Hamilton (DISH), depression scales, transcranial Doppler, neuropsychological testing, and clinical dementia rating (CDR).

RESULTS

Of 161 subjects (mean age 66.2 ± 9.3, female 25%) who completed DISH, 18 had major or minor depression, 17 of whom had a past history of major or minor depression (mean age of onset 35.8 years-old). Pre-CABG depression was associated with greater functional impairment on CDR Sum of Boxes (OR = 3.7, 95% CI: 1.4, 9.7) and worse performance on letter fluency test (OR = 0.90, 95% CI: 0.81, 0.99) and trail-making tests (A: OR = 1.06, 95% CI: 1.01, 1.12; B: OR 1.02, 95% CI: 1.01, 1.04). Pre-CABG depression was not associated with middle cerebral artery (MCA) stenosis.

CONCLUSIONS

Pre-CABG depression is associated with cognitive and functional impairment similar to vascular depression, but we did not find evidence of an association with older age of onset and MCA stenosis. Further studies on white matter disease in this population are needed to examine the vascular depression hypothesis for pre-CABG depression.

The Influence of Emotion Regulation on the Association Between Depression and Heart Rate Variability in Cardiac Patients

OBJECTIVE

Poor vagally mediated heart rate variability (vmHRV) is a mechanism linking depression to coronary heart disease (CHD). Reduced vmHRV is also considered an index of emotion dysregulation-the frequent use of maladaptive emotion regulation strategies, one of the most important being expressive suppression-which is a key component of depression. Therefore, this study aimed to investigate the moderating role of expressive suppression in the relation between depression and vmHRV in patients with CHD.

METHODS

The sample included 235 patients with CHD (mean [standard deviation] age = 61.6 [9.8] years; 12% women) admitted to cardiac rehabilitation after a cardiac intervention. The Beck Depression Inventory-II was administered to assess depressive symptoms. Emotion regulation strategies based on either expressive suppression or cognitive reappraisal were assessed through the Emotion Regulation Questionnaire. Resting electrocardiographic recordings were collected for 5 minutes to compute HRV indices.

RESULTS

Expressive suppression moderated the relation between depressive symptoms and vmHRV ( b = -0.03, p = .012). Patients with lower expressive suppression scores showed no association between depressive symptoms and vmHRV ( b = -0.00, p = .94), whereas those with higher expressive suppression scores showed a significant negative association between depressive symptoms and vmHRV ( b = -0.05, p = .015).

CONCLUSIONS

The use of expressive suppression is likely to potentiate the relation between depressive symptoms and poor vmHRV, which could increase the cardiac risk in these patients. Targeting emotion regulation skills in cardiac rehabilitation programs may be useful for reducing the impact of depression in cardiac patients.

Preoperative anxiety among cardiac surgery patients and its impact on major adverse cardiac events and mortality- A randomized, parallel-group study

Background:

Patients undergoing elective cardiac surgery often experience pre-operative anxiety. Preoperative anxiety influences surgical outcome. There are very few studies which have assessed the impact of clonidine and Gabapentin in the treatment of anxiety especially in Indian populations and its implications on major adverse cardiac events (MACE) and 30 days mortality.

Materials and Methods:

Adult patients aged 18 to 80 years old who were scheduled to have an elective coronary artery by-pass graft (CABG) were included in the study. Those who satisfied the inclusion criteria were given either Gabapentin (800 mg) or Clonidine (300 mcg) 90-120 minutes before the induction. State trait anxiety inventory (STAI) was used to assess anxiety in baseline and taking just before operating room. The primary endpoint was a reduction in the STAI associated with the study drug, while the secondary endpoint was the incidence of MACE in the perioperative period (30 days), which included composite episodes of non-fatal cardiac arrest, chaotic rhythm, acute myocardial infarction, congestive heart failure, cardiac arrhythmia, angina, and death.

Results:

A total of 75 patients were considered for the statistical analysis. The demographic and clinical features of the study participants were similar in both groups. Nearly 75-80% of participants had severe anxiety in the preoperative period while 10-20% had moderate anxiety. While both the drugs showed a reduction in the anxiety levels, the clonidine group fared better (statistically insignificant). The incidence of MACE was similar in both groups.

Conclusion:

The preoperative anxiety levels were high among cardiac surgery patients. Both clonidine and gabapentin were equally effective in reducing the levels of preoperative anxiety. Preoperative STAI scores in the range of 32-53 is not associated with MACE and 30-day mortality among cardiac surgery patients.

Postoperative but not preoperative depression is associated with cognitive impairment after cardiac surgery: exploratory analysis of data from a randomized trial

BACKGROUND

In this study we hypothesize that depression is associated with perioperative neurocognitive dysfunction and altered quality of life one month after surgery.

METHODS

Data were obtained as part of a study evaluating cerebral autoregulation monitoring for targeting arterial pressure during cardiopulmonary bypass. Neuropsychological testing was performed before surgery and one month postoperatively. Testing included the Beck Depression Inventory, a depression symptoms questionnaire (0-63 scale), as well as anxiety and quality of life assessments. Depression was defined as a Beck Depression Inventory score > 13.

RESULTS

Beck Depression data were available from 320 patients of whom cognitive domain endpoints were available from 88-98% at baseline and 69-79% after surgery. This range in end-points data was due to variability in the availability of each neuropsychological test results between patients. Depression was present in 50 (15.6%) patients before surgery and in 43 (13.4%) after surgery. Baseline depression was not associated with postoperative domain-specific neurocognitive function compared with non-depressed patients. Those with depression one month after surgery, though, had poorer performance on tests of attention (p = 0.017), memory (p = 0.049), verbal fluency (p = 0.010), processing speed (p = 0.017), and fine motor speed (p = 0.014). Postoperative neurocognitive dysfunction as a composite outcome occurred in 33.3% versus 14.5% of patients with and without postoperative depression (p = 0.040). Baseline depression was associated with higher anxiety and lower self-ratings on several quality of life domains, these measures were generally more adversely affected by depression one month after surgery.

CONCLUSIONS

The results of this exploratory analysis suggests that preoperative depression is not associated with perioperative neurocognitive dysfunction, but depression after cardiac surgery may be associated with impairment in in several cognitive domains, a higher frequency of the composite neurocognitive outcome, and altered quality of life.

Baseline depressive symptoms, personal control, and concern moderate the effects of preoperative psychological interventions: the randomized controlled PSY-HEART trial

This study examined whether baseline (3–14 days pre-surgery) levels of (i) depressive or (ii) anxiety symptoms and (iii) illness beliefs moderate the effects of additional preoperative interventions before coronary artery bypass graft surgery on (i) depressive or (ii) anxiety symptoms and (iii) illness beliefs 1 day before surgery, 1 week and 6 months after surgery. In the PSY-HEART trial, 115 patients were assessed. They were randomized into one of three groups: 1. receiving standard medical care only (SMC), additional psychological interventions: 2. aiming to optimize patients’ expectations (EXPECT), or 3. focusing on emotional support. Patients with a higher baseline level of depressive symptoms receiving a preoperative psychological intervention indicated lower depressive symptoms 6 months after surgery compared to SMC. EXPECT increased personal control and concern levels in patients with low baseline personal control/concern 1 day before surgery. Brief preoperative psychological interventions can improve psychological outcomes in heart surgery patients. Baseline status may moderate these effects. The study has been approved by the medical ethics committee of the Philipps University of Marburg and has been pre-registered at www.clinicaltrials.gov (NCT01407055) on August 1, 2011.

The Effect of Pre-operative Psychological Interventions on Psychological, Physiological, and Immunological Indices in Oncology Patients: A Scoping Review

Introduction

The stressful pre-operative period exerts a profound impact on psychological, physiological and immunological outcomes. Oncological surgeries, in particular, elicit significantly higher stress responses than most other surgeries. Managing these responses through psychological interventions may improve long-term outcomes. The purpose of the current research was to review studies that have explored pre-operative psychological interventions in cancer patients in order to map the types of current interventions and provide an initial assessment of whether these interventions improved psychological, physiological, and/or immunological indices as well as long-term cancer outcomes.

Methods

A systematic literature search for studies that included pre-operative psychological interventions in oncology patients was conducted, using the databases PubMed and Web of Science. Inclusion criteria included studies pertaining to oncological surgery in adults, study designs that included a clearly defined pre-operative psychological intervention and control group.

Results

We found 44 studies, each using one of the following interventions: psychoeducation, cognitive interventions, relaxation techniques, integrated approaches. All the studies reported improved immediate post-operative psychological, physiological, and/or immunological outcomes. Only a few studies addressed long-term cancer outcomes, and only one reported improved survival.

Conclusions

Research on pre-operative interventions with cancer patients is missing systematic methods. Studies provide varying results, which makes it difficult to compare them and reach reliable conclusions. There is considerable heterogeneity in the literature regarding the specific intervention used, the timing of intervention, the characteristics of the patients studied and the outcome measures. In order to improve research in this field, including the measurement of long-term outcomes, we suggest some steps that should be taken in further research.

Depressive symptoms, perceived control and quality of life among patients undergoing coronary artery bypass graft: a prospective cohort study

BACKGROUND

Coronary artery bypass graft surgery (CABG) is an intervention directed toward improving the Quality of Life (QoL) for patients with coronary artery disease. Depression can affect QoL negatively among this population. Perceived control (PC) decreased the effect of anxiety on QoL, however, this effect has not been well-studies regarding depression. Therefore, the purpose of this study was to check the effect of depression on QoL among CABG patients and to determine if preoperative PC moderates this effect.

METHODS

This was a prospective observational cohort study conducted on a consecutive sample of 200 patients from three hospitals in Amman, Jordan. Depression Anxiety and Stress Scale, Short-Form Health Survey-36, and Arabic version of the Control Attitude Scale-Revised were used to measure depressive symptoms, QoL and PC respectively. Data were analyzed using t test and step wise multiple regression followed by simple slope analysis.

RESULTS

Postoperative Physical Component Summary (PCS) was better than preoperative PCS (mean ± SD: 38.2 ± 9.4 vs. 36.6 ± 9.5, P < 0.001). Postoperative Mental Component Summary (MCS) was better than preoperative MCS (mean ± SD: 44.3 ± 11.5 vs. 41.4 ± 11.4, P < 0.001). Preoperative depression was higher than postoperative depression; (mean ± SD: 12.8 ± 6.8 vs.11.1 ± 6.7, P < 0.01). Simple slope analysis was significant (simple slope = 0.41, t = 6.1, P < 0.001), indicating the moderating effect of PC.

CONCLUSION

Patients undergoing CABG surgery had poor QoL and high levels of depression. Perceived control moderated this relationship and improve QoL. Assessing depression levels and implantation of interventions to enhance perceived control levels prior to operation might improve QoL.

Anxiety and depression scores in patients subjected to aortic and iliac aneurysm repair procedures

OBJECTIVE

This study examines the changes in anxiety and depression scores of 84 patients subjected to aortic or iliac aneurysm correction with no previous psychiatric history.

METHODS

Patients were referred to the evaluation using the Beck Anxiety and Depression Inventories no more than 3 days before surgery (i.e., preoperative [Pre-Op]), 30 days after revascularization (i.e., Early postoperative [PO]), and at least 6 months after revascularization (i.e., Late PO).

RESULTS

Mean anxiety scores declined from baseline at both the Early (mean difference: 2.75, p<0.001) and Late PO (mean difference: 2.74, p=0.001). The depression levels showed no significant variation in either evaluation (Early PO; mean difference: -0.84, p>0.05, Late PO: 0.87, p=0.05). A more severe degree of anxiety at baseline was related to better anxiety results both in the Early PO (p=0.041) and Late PO (p=0.008). An endovascular technique was related to the improvement in depression symptoms in the Early PO (p=0.01) but the worsening of the symptoms in the Late PO (p=0.033).

CONCLUSIONS

Patients subjected to aortoiliac aneurysm corrections have a higher incidence of anxiety and depressive symptoms. Anxiety symptoms, but not the depressive ones, improved considerably following the successful treatment. The formal psychiatric evaluation may be beneficial for patients with less improvement in the symptom.

The Association Between Depressive Symptoms and Length of Hospital Stay Following Coronary Artery Bypass Graft is Moderated by Perceived Control

PURPOSE

Depressive symptoms can negatively influence patient outcomes after coronary artery bypass graft surgery (CABG). Preoperative depressive symptoms can be associated with a longer hospitalization. Perceived control moderates the effect of anxiety on length of stay (LOS) among CABG patients, but its effect on depressive symptoms and LOS is not well studied. This study tests whether perceived control moderates the relationship between depressive symptoms and LOS among patients following CABG.

PATIENTS AND METHODS

This prospective cohort study was conducted on 220 participants recruited from three hospitals in Jordan. Participants' depressive symptom levels were measured using the depression subscale of the Hospital Anxiety and Depression Scale. Perceived control was measured by the Arabic version of the Control Attitude Scale-Revised. Length of stay was obtained from medical records. Data were analyzed using multiple regression and simple slope analysis.

RESULTS

Females had higher levels of depressive symptoms (mean [SD]: 16.7 [5.2] vs 11.6 [5.6], P<0.05), and longer LOS (mean [SD]: 17.5 [12.7] vs 10.3 [9.0], P<0.001) compared to male patients. Being female increased the length of stay by 0.18 days. Every one-unit increase in preoperative depressive symptoms increased LOS by 0.37 days. Perceived control has a protective effect; every one unit increase in perceived control decreased LOS by 0.28 days. Moreover, perceived control moderates the relationship between depressive symptoms and LOS.

CONCLUSION

This study suggests that depressive symptoms and perceived control play an important role in the recovery among post-CABG patients. Application of policies to assess depressive symptoms and improve perceived control prior to CABG by health care providers might decrease morbidity and mortality.

Associations of Preoperative Self-rated Symptoms of Anxiety and Depression on Length of Hospital Stay and Long-term Quality of Life in Patients Undergoing Cardiac Surgery

BACKGROUND

Anxiety and depression are often associated with cardiovascular diseases. Nevertheless, few study authors have investigated psychological effects on immediate and long-term cardiac surgery-related outcomes, such as surgical complications, length of hospital stay (LOS), and long-term health-related quality of life (HRQoL).

OBJECTIVES

The aims of this study were to (a) investigate the role of preoperative symptoms of anxiety and depression in predicting LOS in a sample of surgical patients and (b) evaluate the impact of preoperative symptoms of anxiety and depression on the patients' HRQoL 3 months after surgery.

METHODS

One hundred fifty-one patients waiting for surgery were included. To evaluate symptoms of anxiety and depression, the Hospital Anxiety and Depression Scale was used. Multiple regression analyses were conducted to evaluate the impact of both clinical and psychological factors on LOS, whereas quantile regression was performed to assess their effect on the patients' HRQoL 3 months after surgery.

RESULTS

The multiple regression shows that EuroSCORE, length of endotracheal intubation, and anxiety symptoms predict LOS. The multiple quantile regression analyses also show that both symptoms of anxiety and depression predict a negative HRQoL up to 3 months after surgery.

CONCLUSION

Preoperative symptoms of anxiety predict the patients' LOS, and both symptoms of anxiety and depression predict a scarce HRQoL 3 months after cardiac surgery. These results suggest the need for implementing presurgical in-hospital screening procedures for both symptoms of anxiety and depression. Finally, focused psychological interventions should be implemented for reducing inpatients' hospital LOS and improving their future quality of life.

Impact of cognitive behavioral therapy on depression symptoms after transcatheter aortic valve replacement: A randomized controlled trial

BACKGROUND

Depression is a significant concern after cardiac surgery and has not been studied in patients undergoing transcatheter aortic valve replacement (TAVR). We sought to examine the prevalence of pre-procedure depression and anxiety symptoms and explore whether brief bedside cognitive behavioral therapy (CBT) could prevent post-TAVR psychological distress.

METHODS

We prospectively recruited consecutive TAVR patients and randomized them to receive brief CBT or treatment as usual (TAU) during their hospitalization. Multi-level regression techniques were used to evaluate changes by treatment arm in depression, anxiety, and quality of life from baseline to 1 month post-TAVR adjusted for sex, race, DM, CHF, MMSE, and STS score.

RESULTS

One hundred and forty six participants were randomized. The mean age was 82 years, and 43% were female. Self-reported depression and anxiety scores meeting cutoffs for clinical level distress were 24.6% and 23.2% respectively. Both TAU and CBT groups had comparable improvements in depressive symptoms at 1-month (31% reduction for TAU and 35% reduction for CBT, p = .83). Similarly, both TAU and CBT groups had comparable improvements in anxiety symptoms at 1-month (8% reduction for TAU and 11% reduction for CBT, p = .1). Quality of life scores also improved and were not significantly different between the two groups.

CONCLUSIONS

Pre-procedure depression and anxiety may be common among patients undergoing TAVR. However, TAVR patients show spontaneous improvement in depression and anxiety scores at 1-month follow up, regardless of brief CBT. Further research is needed to determine whether more tailored CBT interventions may improve psychological and medical outcomes.

Preoperative Depressive Symptoms Associated with Poor Functional Recovery after Surgery

BACKGROUND/OBJECTIVES

Depression screening and treatment for older adults are recommended in Age-Friendly Health Systems. Few studies have evaluated the association between depressive symptoms and postoperative functioning. We aimed to determine the association between varying levels of depressive symptoms in the preoperative setting with postoperative functional recovery.

DESIGN

Prospective cohort study.

SETTING

Two academic hospitals in Boston, Massachusetts.

PARTICIPANTS

Surgical patients aged 70 and older (N = 560).

MEASUREMENTS

Participants were assessed preoperatively and 1 year postoperatively. Preoperative evaluation included the 15-item short-form Geriatric Depression Scale (GDS). Results were categorized as low (GDS = 0-1), moderate (2-5), or high (6-15) symptom burden. Primary outcome was 1-year instrumental activities of daily living functional decline. Secondary outcomes included hospital stay longer than 5 days, discharge to post-acute care (PAC) facility, and readmission within 30 days.

RESULTS

Mean participant age was 76.6 ± 5 years, 58% were women, 81% underwent an orthopedic operation, 13% gastrointestinal, 6% vascular; 13% had functional decline at 1 year after their operation (by symptom burden: low = 5.5%; moderate = 14.8%, and high = 38.6%). After adjusting for age, sex, and comorbidity, those with moderate or high depressive symptoms demonstrated greater odds of functional decline at 1 year compared with those with a low symptom burden (moderate: adjusted odds ratio [AOR] = 2.7; 95% confidence interval [CI] = 1.3-5.3; high: AOR = 9.3; 95% CI = 4.2-20.6), discharge to PAC facility (moderate: AOR = 1.7; 95%CI = 1.2-2.6; high: AOR = 2.7; 95% CI = 1.4-5.1) but demonstrated no significant association with 30-day readmission or hospital length of stay longer than 5 days.

CONCLUSION

Greater burden of preoperative depressive symptoms is associated with increased likelihood of functional decline at 1 year after surgery and of discharge to PAC facility. Preoperative assessment of the burden of depressive symptoms in older adults undergoing elective surgery may be helpful in identifying patients at high risk of poor outcomes.

Anxiety and Depression Symptomatology Related to Inspiratory Muscle Strength and Functional Capacity in Preoperative Cardiac Surgery Patients: A Preliminary Cross-sectional Study

BACKGROUND

Poor psychological health and cardiorespiratory fitness prior to open heart surgery (OHS) might be predictors of postoperative pulmonary complications that lead to morbidity and mortality. Assessment of physical and psychological conditions should be considered for patients receiving OHS, to possibly prevent these complications. This study investigates how inspiratory muscle strength (IMS) and functional capacity (FC) relate to the psychological health of preoperative cardiac surgery patients.

METHOD

A cross-sectional study was designed before OHS; the 6-minute walk test and IMS were performed on patients who were admitted for OHS. All participants were requested to complete Hospital Anxiety and Depression Scale. Pearson correlation and hierarchal regression analysis were performed to determine the relationships between IMS and FC and psychological conditions (anxiety and depression).

RESULTS

Overall, 36 males and 28 females aged 56.89±10.23 years were recruited. Significant relationships were observed between IMS and anxiety and depression symptoms (r = -0.33 and r = -0.27, respectively). Anxiety was negatively related to FC (r = -0.25). These relationships remained significant after adjustment for age, sex, and body mass index (BMI) (∆R 2 = 0.11 and ∆R 2 = 0.09). In addition, anxiety was also related to FC after controlling for age, sex, and BMI (∆R 2 = 0.09).

CONCLUSION

Among patients undergoing OHS, those with a higher level of depression or anxiety had a lower cardiorespiratory fitness than those with a low level of depression or anxiety.

Psychological Preparation for Cardiac Surgery

PURPOSE OF REVIEW

To review the current state of preoperative psychological preparation to improve outcomes after cardiac surgery.

RECENT FINDINGS

Preoperative psychosocial factors are associated with short- and long-term outcomes after cardiac surgery. There are several approaches to optimize patients' preoperative psychological status with promising effects on postoperative outcomes (e.g., less complications, improved quality of life). Preoperative psychological preparation often aims to improve patients' knowledge or social support and to modify and optimize expectations and illness beliefs. Preoperative psychological preparation is gaining importance for cardiac surgery. However, patients' psychological status still does not get as much attention as it deserves. Preoperative psychological preparation seems to have positive effects on postoperative outcomes. Since overall evidence is still weak, further studies are warranted to understand which intervention works best for whom and why.

Anxiety and depression in patients who undergo a cerebrovascular procedure

Background

Observe the relationship of anxiety and depression on quality of life outcomes after open and endovascular cerebrovascular procedures.

Methods

We retrospectively analyzed 349 patients who underwent a procedure for aneurysm, arteriovenous malformation, intraparenchymal hemorrhage, carotid stenosis, acute stroke, and conventional catheter angiogram over three years at a community hospital. We correlated pre-procedural anxiety and depression with Global Physical Health, Global Mental Health, and Modified Rankin Scale scores. We performed univariate and multivariate linear and logistic regression analyses adjusting for past medical history and sociodemographic factors.

Results

Anxiety or depression occurred in 18 % of patients. Patients with anxiety or depression were more likely to be female (81% vs 60.8%; p = 0.002) and younger (54 vs. 59 years old; p = 0.025). The groups did not differ in type or urgency of procedure, smoking or history of diabetes. Patients with anxiety or depression reported lower mental health scores at 30 days (45.1 vs 48.2; p = 0.002) post-procedure. In multivariate analyses, anxious or depressed patients had worse mental health scores at 30 days (t = − 2.893; p = 0.008) than those who did not have a history of anxiety or depression. There was no difference between groups in length of stay, mortality, physical health t-scores, functionality scores, or six month quality of life outcomes.

Conclusions

Patients undergoing cerebrovascular procedures who self-reported anxiety or depression showed a significant difference in mental health outcomes at 30 days, but six month mental health and other medical and functional outcomes measures were similar to patients without these diagnoses.

Selective serotonin re-uptake inhibitors: risk of blood product transfusion and inotrope requirements in patients undergoing cardiac surgery

Background

Patients undergoing cardiac surgery exhibit a high prevalence of concomitant depression. The first-line pharmacological treatment modality for depression includes selective serotonin re-uptake inhibitors (SSRIs). Despite their efficacy, SSRIs are not without their own side-effects.

Methods

We conducted a retrospective observational study to determine if preoperative SSRI therapy was associated with higher rates of perioperative blood product transfusion, and higher incidence of inotropic requirements in patients undergoing elective cardiac surgery. A total of 2,943 patients were included in the study. Patients undergoing emergency surgery or surgery without cardiopulmonary bypass (CPB) were excluded. Based on preoperative SSRI status patients were classed into either SSRI group (n=95), or non-SSRI group (n=2,848). Data was acquired from the Toronto Anesthesia Perioperative Outcomes Database.

Results

Baseline preoperative variables included age, sex, body surface area, smoking history, past medical history, preoperative medications, baseline hemoglobin, creatinine, and planned surgical procedures. Perioperative transfusion of blood products and inotropic utilization were collected. Univariate analysis showed that patients in SSRI group were more likely to be female, have history of congestive heart failure, preoperative anemia, and likelihood of having more complex surgery, received more inotropes and fresh frozen plasma, and were more likely to have chest reopening for bleeding. There was no difference in postoperative morbidity and mortality between the SSRI and non-SSRI groups. Separate statistical models were constructed to determine association between transfusion of red blood cells, fresh frozen plasma, platelets, composite inotrope use, and SSRI therapy. SSRI variable was not significant in any of the multivariate models, indicating the lack of evidence of association between the SSRIs and either blood product transfusion, or inotrope requirements. Significant predictors of blood product transfusion included smaller body surface area, female gender, older age, low baseline hemoglobin levels, elevated creatinine, increased CPB, presence of deep hypothermic circulatory arrest, complex cardiac surgery, history diabetes mellitus, and congestive heart failure. Predictors of inotrope use included older age, elevated creatinine, increased CPB time, history of diabetes mellitus, and congestive heart failure.

Conclusions

The current study suggests that modifying preoperative therapy pertinent to SSRI treatment in patients undergoing elective cardiac surgery is not warranted.

Pre-operative depression predicted longer hospital length of stay among patients undergoing coronary artery bypass graft surgery

Purpose: Coronary artery bypass graft surgery (CABG) is a common and remarkably effective treatment for coronary heart disease, improving health status and enhancing quality of life. However, some outcomes after surgery remain unexplained, including psychological factors such as depression. The prevalence rates of pre- and post-operative depression among CABG patients are high, which is associated with negative short- and long-term outcomes. This study explores the impacts of pre-operative depressive symptoms on post-operative hospital length of stay (LOS) among patients undergoing CABG in Jordan. Patients and methods: This was a non-experimental, prospective observational study among 227 CABG patients recruited from 5 hospitals in Amman, Jordan. Depression was measured within an average of two weeks prior and one month after the operation using the Hospital Anxiety and Depression Scale. Length of stay was abstracted from medical records after discharge. Results: The average post-operative LOS was 11.40±10.41 days. The average pre-operative depression level was moderate; 12.76±6.80 and 42.47% complained of varying levels of depressive symptoms. The average post-operative depression level was moderate; 11.11±6.78 and 40.53% complained of varying levels of depressive symptoms. In stepwise regression models, depression scores and female gender were independent predictors that increased post-operative LOS. On the other hand, high income (≥1501$/month) and use of statins had protective effects and decreased post-operative LOS. The model explained 22.4% of the total variance regarding LOS. Conclusion: Pre-operative depressive symptoms increased post CABG LOS. Application of policies and depression assessment protocols prior to CABG by health care providers can identify high-risk groups (eg, females), so appropriate interventions can be designed and implemented to decrease morbidity and mortality.

Longitudinal changes in depression screening results in cardiac surgery patients

Background

The aim was to investigate longitudinal changes in depression screening results by sex up to one year following cardiac surgery.

Methods

We introduced a depression screening project using the Patient Health Questionnaire (PHQ-9) including patients between 2013-2016. Patients received the PHQ-9 prior to surgery, and at follow-up one year after surgery. We analyzed changes in PHQ-9 scores and screening status from baseline to 1-year follow-up.

Results

Screening results were obtained in 1,133 patients prior to surgery, and after one year, 1,084 patients were alive and of those 897 (83%) patients completed the follow-up PHQ-9 questionnaire. A positive depression screen at baseline was twice as common in women compared to men. A total of 547 (92%) men and 173 (91%) women who were screening negative at baseline were still screening negative at 1-year follow-up. There was no difference between men and women. A lower proportion of men compared with women (44% vs. 61%) improved from screening positive at baseline to screening negative at 1-year follow-up (P=0.069). The total PHQ-9 score difference between baseline and one year had increased with 0.23 points among men and decreased with 0.68 points in women.

Conclusions

We found that twice as many women as men had a positive depression screen at baseline, and that almost 10% of all who were screening negative at baseline, were screening positive after one year. An improvement in depressive symptoms (transition from a screening positive state to a negative screening state) was more common among women than men after one year of follow up.

Toward a very brief quality of life enjoyment and Satisfaction Questionnaire

OBJECTIVE

To develop and evaluate a new brief self-report measure of satisfaction/quality of life in depressed outpatients.

METHODS

Using the Quality of Life Enjoyment and Satisfaction Questionnaire Short-Form (Q-LES-Q-SF) self-report from Step-1 (n = 2181) of the STAR*D trial, items were selected based on their magnitude of change with treatment and correlation with 16-item Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR₁₆). Psychometric analyses were conducted. Replication of scale performance was assessed with STAR*D Step-2 data (n = 250).

RESULTS

The 7 items selected ("Mini-Q-LES-Q") rated satisfaction with work, household activities, social and family relations, leisure time activities, daily function and sense of well-being in the past week. This uni-dimensional scale captured 83-94% variance in Q-LES-Q-SF and had acceptable Item Response and Classical Test Theory characteristics. Baseline to exit percent changes in the Mini-Q-LES-Q and the QIDS-SR₁₆ were significantly, modestly related (r = -0.552) (Step-1) and replicated (r = -0.562) (Step-2). The Mini-Q-LES-Q detected the expected improvement in satisfaction/quality of life in acute treatment, yet also identified residual deficits expected in many at acute-phase exit.

LIMITATIONS

Population norms are yet undefined. Concurrent validity with detailed, well-validated scales that assess the seven Quality of Life domains incorporated in the Mini-Q-LES-Q remains unestablished. Sensitivity to symptom changes induced by psychotherapy or somatic therapies or sensitive to the effects of therapies aimed at enhancing quality of life enjoyment and function is unknown.

CONCLUSION

The 7-item Mini-Q-LES-Q self-report measure satisfaction/quality of life has acceptable psychometric properties, reflects change with depressive symptom reduction, and detects residual deficits in this key clinical outcome.

Does pre-operative anxiety and/or depression affect patient outcome after primary knee replacement arthroplasty?

BACKGROUND

Chronic pain is associated with psychological distress, most commonly manifested as anxiety and/or depression.

METHODS

In order to investigate the effect of such distress on outcome from knee arthroplasty, we prospectively investigated the anxiety and depression levels of 104 patients undergoing a total of 107 primary knee arthroplasty procedures and the outcomes they achieved pre-operatively and at six weeks, one year and seven years post-operatively. The Hospital Anxiety and Depression Scale was used to record psychological status. Oxford Knee Score and American Knee Society Score were used to record functional outcomes.

RESULTS

Forty-four percent (47/107) of the patients had an abnormal pre-operative anxiety and/or depression score. Mean anxiety and depression scores improved at six weeks and one year of follow-up, but then deteriorated slightly at seven years, albeit not back to baseline. Knee scores showed similar patterns over time. Regardless of pre-operative psychological status, mean AKSS Knee scores improved at six weeks and further improved at one year post-op. They then showed slight deterioration at seven years, but remained significantly better than pre-op.

CONCLUSIONS

Psychological distress is common in our patients pre-operatively. Improvements in knee pain and function as a result of surgery correlate well with lower levels of psychological distress post-operatively. Knee replacement surgery positively influences all of the outcome measures studied rather than recovery being negatively influenced by pre-operative states. Knee replacement arthroplasty is not contra-indicated by pre-operative psychological distress. Successful knee replacement improves knee pain and function, as well as symptoms of anxiety and depression. These improvements persist for many years after the surgery.

Association Between Anxiety, Depression, and Post-traumatic Stress Disorder and Outcomes After Ischemic Stroke

Background: Stroke patients are known to be at risk of developing anxiety, depression, and post-traumatic stress disorder (PTSD). Objective: To determine the overlap between anxiety, depression, and PTSD in patients after stroke and to determine the association between these disorders and quality of life, functional status, healthcare utilization, and return to work. Methods: A cross-sectional telephone survey was conducted to assess for depression, anxiety, PTSD, and health-related outcomes 6-12 months after first ischemic stroke in patients without prior psychiatric disease at a single stroke center. Results: Of 352 eligible subjects, 55 (16%) completed surveys. Seven subjects (13%) met criteria for probable anxiety, 6 (11%) for PTSD, and 11 for depression (20%). Of the 13 subjects (24%) who met criteria for any of these disorders, 6 (46%) met criteria for more than one, and 5 (39%) met criteria for all three. There were no significant differences in baseline characteristics, including stroke severity or neurologic symptoms, between those with or without any of these disorders. Those who had any of these disorders were less likely to be independent in their activities of daily living (ADLs) (54 vs. 95%, p < 0.001) and reported significantly worse quality of life (score of 0-100, median score of 50 vs. 80, p < 0.001) compared to those with none of these disorders. Conclusions: Anxiety, depression, and PTSD are common after stroke, have a high degree of co-occurrence, and are associated with worse outcomes, including quality of life and functional status.

Impact of New-Onset Postoperative Depression on Readmission Outcomes After Surgical Coronary Revascularization

BACKGROUND

Depression affects between 10% and 40% of cardiac surgery patients and is associated with significantly worse outcomes. The incidence and impact of new-onset depression beyond acute follow-up remain ill-defined. The present study aimed to evaluate the incidence, risk factors, and prognostic implication of depression on 90-d readmission rates after coronary artery bypass grafting (CABG) surgery.

METHODS

A retrospective cohort study was performed identifying adult patients without prior depression who underwent CABG surgery using the 2010-2014 National Readmissions Database. CABG patients who were readmitted more than 2 wk but within 90 d of discharge were categorized based on the presence of new-onset depression. Association between the development of new-onset depression and rehospitalization were morbidity, mortality, costs, and length of stay (LOS) and were examined using multivariable regression.

RESULTS

During the study period, 1,001,945 patients underwent CABG. Of these, 11.7% of patients were readmitted after 14 d but within 90 d of discharge with 5.1% of these patients having a diagnosis of new-onset depression. Postoperative new-onset depression was not associated with increased readmission morbidity, costs, or LOS. Mortality in new-onset depression readmissions was 1.2%, compared with 2.3% in all readmitted patients (P = 0.014). Depression was associated with lower odds of mortality (OR = 0.56, P = 0.02).

CONCLUSIONS

New-onset depression following CABG discharge was not associated with increased odds of mortality, morbidity, costs, or increased LOS on readmission. Rather, new-onset depression is associated with decreased odds of readmission mortality. Overall, CABG readmissions are decreasing, whereas the rate of new-onset depression is slightly increasing. Implementation of routine depression screening tools in postoperative CABG care may aid in early detection and management of depression to enhance postoperative recovery and quality of life.

A Scoping Study of Psychosocial Factors in Women Diagnosed With and/or Treated for Pelvic Organ Prolapse

OBJECTIVE

Pelvic organ prolapse (POP) is prevalent and can impact women's physical and psychosocial health. To develop interventions that support this population, an understanding of the state of research on psychosocial factors related to POP is essential. We conducted a scoping study focused on the psychosocial experience of women with POP. The purpose of this review was to (1) inventory and describe the current state of knowledge of the psychosocial experience of women with POP, (2) identify gaps in knowledge, and (3) identify targets for future research.

METHOD

Electronic databases PsycINFO, PubMed, EMBASE, and CINAHL were searched through November 1, 2017.

RESULTS

Of 524 titles reviewed, 103 articles met all inclusion criteria. Articles were grouped by the disease period (ie, prediagnosis, diagnosis/preintervention, intervention, follow-up, and mixed) and psychosocial factors. Most articles (n = 73) focused on women undergoing intervention. Articles focusing on the preintervention period was the next largest category (n = 14). Follow-up after intervention (n = 8) and samples of mixed disease periods (n = 7) were less common. One article focused on women before diagnosis. Articles focused on quality of life (QOL; n = 79), sexual function (n = 51), satisfaction (n = 16), body image (n = 13), psychological distress (n = 4), and knowledge (n = 3).

CONCLUSIONS

Research on the psychosocial experience of POP has largely focused on changes in QOL and sexual function. Future research should target emotional experience of women with POP; relationships among QOL, psychological distress, body image, and sexual function; and psychosocial factors related to treatment outcomes.

Prevalence of depression and its associated factors in patients post-coronary artery bypass graft surgery

This research aimed to determine the depression level and its correlation experienced by post-coronary artery bypass graft patients after being discharged from cardiac intensive care units. A cross-sectional design was employed for assessing variables. The Self-rating Depression Scale, as proposed by Zung, was used by the researchers on a convenience sample of Jordanian patients (N = 143) who were approached soon after their discharge from the targeted units. The results suggested that the level of depression among Jordanian patients was relatively high (M = 62.7, SD = 5.6). Moreover, depression was significantly higher among female, unmarried and unemployed patients. Patients who received their information about coronary artery bypass graft surgery from nurses had a lower level of depression. Age, length of stay in the cardiac intensive care unit and hospital type significantly predicted the level of depression. The research concluded that the post-coronary artery bypass graft patients who experienced an early onset depression required more attention to highlight the importance of supportive interventions.

The effect of a peer support intervention on early recovery outcomes in men recovering from coronary bypass surgery: A randomized controlled trial

BACKGROUND AND AIM

Examine the effect of a professionally-guided telephone peer support intervention on recovery outcomes including depression, perceived social support, and health services utilization after coronary artery bypass graft surgery (CABG).

METHODS

A randomized controlled trial was conducted with post-coronary artery bypass graft surgery men ( N=185) who were randomized before hospital discharge. The intervention arm received telephone-based peer support through weekly telephone calls from a peer volunteer over six weeks, initiated within 3-4 days of discharge.

RESULTS

Although a significant difference was detected in pre-intervention depression scores at discharge, there were no differences between groups in changes in depression scores at six weeks ( p=0.08), 12 weeks (0.49) or over time ( p=0.51); and no significant differences in perceived social support scores over time ( p=0.94). At 12 weeks, the intervention group had significantly lower incidence of health services utilization (family physician ( p=0.02) and emergency room ( p=0.04)).

CONCLUSIONS

Healthcare providers need to continue to investigate novel interventions to enhance social support and reduce depression in cardiac patients.

Psychological interventions for acute pain after open heart surgery

BACKGROUND

This is an update of a Cochrane review previously published in 2014. Acute postoperative pain is one of the most disturbing complaints in open heart surgery, and is associated with a risk of negative consequences. Several trials investigated the effects of psychological interventions to reduce acute postoperative pain and improve the course of physical and psychological recovery of participants undergoing open heart surgery.

OBJECTIVES

To compare the efficacy of psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention control in adults undergoing open heart surgery for pain, pain medication, psychological distress, mobility, and time to extubation.

SEARCH METHODS

For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Web of Science, and PsycINFO for eligible studies up to February 2017. We used the 'related articles' and 'cited by' options of eligible studies to identify additional relevant studies. We checked lists of references of relevant articles and previous reviews. We searched the ProQuest Dissertations and Theses Full Text Database, ClinicalTrials and the WHO International Clinical Trials Registry Platform to identify any unpublished material or ongoing trials. We also contacted the authors of primary studies to identify any unpublished material. In addition, we wrote to all leading heart centres in Germany, Switzerland, and Austria to check whether they were aware of any ongoing trials.

SELECTION CRITERIA

Randomised controlled trials comparing psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention in adults undergoing open heart surgery.

DATA COLLECTION AND ANALYSIS

Two review authors (SZ and SK) independently assessed trials for eligibility, estimated the risk of bias and extracted all data. We calculated effect sizes for each comparison (Hedges' g) and meta-analysed data using a random-effects model. We assessed the evidence using GRADE and created 'Summary of findings' tables.

MAIN RESULTS

We added six studies to this update. Overall, we included 23 studies (2669 participants).For the majority of outcomes (two-thirds), we could not perform a meta-analysis since outcomes were not measured, or data were provided by one trial only.No study reported data on the number of participants with pain intensity reduction of at least 50% from baseline. Only one study reported data on the number of participants below 30/100 mm on the Visual Analogue Scale (VAS) in pain intensity (very low-quality evidence). Psychological interventions did not reduce pain intensity in the short-term interval (g 0.39, 95% CI -0.18 to 0.96, 2 studies, 104 participants, low-quality evidence), medium-term interval (g -0.02, 95% CI -0.24 to 0.20, 4 studies, 413 participants, moderate-quality evidence) or in the long-term interval (g 0.05, 95% CI -0.20 to 0.30, 2 studies, 200 participants, moderate-quality evidence).No study reported data on median time to re-medication or on number of participants re-medicated. Only two studies provided data on postoperative analgesic use in the short-term interval, showing that psychological interventions did not reduce the use of analgesic medication (g 1.18, 95% CI -2.03 to 4.39, 2 studies, 104 participants, low-quality evidence). Studies revealed that psychological interventions reduced mental distress in the medium-term (g 0.37, 95% CI 0.13 to 0.60, 13 studies, 1388 participants, moderate-quality evidence) and likewise in the long-term interval (g 0.32, 95% CI 0.10 to 0.53, 14 studies, 1586 participants, moderate-quality evidence). Psychological interventions did not improve mobility in the medium-term interval (g 0.23, 95% CI -0.22 to 0.67, 3 studies, 444 participants, low-quality evidence), nor in the long-term interval (g 0.09, 95% CI -0.10 to 0.28, 4 studies, 458 participants, moderate-quality evidence). Only two studies reported data on time to extubation, indicating that psychological interventions reduced the time to extubation (g 0.56, 95% CI 0.08 to 1.03, 2 studies, 154 participants, low-quality evidence).Overall, the very low to moderate quality of the body of evidence on the efficacy of psychological interventions for acute pain after open heart surgery cannot be regarded as sufficient to draw robust conclusions.Most 'Risk of bias' assessments were low or unclear. We judged selection bias (random sequence generation) and attrition bias to be mostly low risk for included studies. However, we judged the risk of selection bias (allocation concealment), performance bias, detection bias and reporting bias to be mostly unclear.

AUTHORS' CONCLUSIONS

In line with the conclusions of our previous review, there is a lack of evidence to support or refute psychological interventions in order to reduce postoperative pain in participants undergoing open heart surgery. We found moderate-quality evidence that psychological interventions reduced mental distress in participants undergoing open heart surgery. Given the small numbers of studies, it is not possible to draw robust conclusions on the efficacy of psychological interventions on outcomes such as analgesic use, mobility, and time to extubation respectively on adverse events or harms of psychological interventions.

Pre-surgical depression and anxiety and recovery following coronary artery bypass graft surgery

We aimed to explore the combined contribution of pre-surgical depression and anxiety symptoms for recovery following coronary artery bypass graft (CABG) using data from 251 participants. Participants were assessed prior to surgery for depression and anxiety symptoms and followed up at 12 months to assess pain and physical symptoms, while hospital emergency admissions and death/major adverse cardiac events (MACE) were monitored on average 2.68 years after CABG. After controlling for covariates, baseline anxiety symptoms, but not depression, were associated with greater pain (β = 0.231, p = 0.014) and greater physical symptoms (β = 0.194, p = 0.034) 12 months after surgery. On the other hand, after controlling for covariates, baseline depression symptoms, but not anxiety, were associated with greater odds of having an emergency admission (OR 1.088, CI 1.010–1.171, p = 0.027) and greater hazard of death/MACE (HR 1.137, CI 1.042–1.240, p = 0.004). These findings point to different pathways linking mood symptoms with recovery after CABG surgery.

Association between preoperative depression and long-term survival following coronary artery bypass surgery - A systematic review and meta-analysis

BACKGROUND

Depression is common in patients with cardiovascular disease. The importance of preoperative depression for long-term survival following coronary artery bypass grafting (CABG) is not well known. The aim was to provide a summary estimate of the association between preoperative depression and long-term survival in adults who underwent CABG.

METHODS

We did a systematic search of MEDLINE, EMBASE, Cochrane Library, PsycINFO, Web of Science, and PubMed from inception to November, 2015, including cohort studies with at least one month of follow-up that reported hazard ratios (HR) and 95% confidence intervals (CI) for long-term all-cause mortality following CABG in patients with preoperative depression compared to non-depressed patients. Two reviewers independently extracted data on populations, exposure, outcome, risk of bias, and quality of evidence. We calculated HR and 95% CIs for all-cause mortality using random-effects meta-analyses and performed subgroup and sensitivity analyses.

RESULTS

Seven studies were included with a combined study population of 89,490 patients (4002 depressed/85,488 non-depressed). All studies observed a positive association between preoperative depression and all-cause mortality, and in 4 studies the association was statistically significant. Patients with depression had a pooled hazard ratio of 1.46 (95% CI: 1.23-1.73, p<0.0001) for all-cause mortality with moderate heterogeneity (I(2)=50.1%, p=0.061).

CONCLUSIONS

This systematic review and meta-analysis indicates that patients with preoperative depression are at increased risk for long-term, all-cause mortality following CABG compared with those without depression. Systematic screening for depression prior to cardiac surgery could identify those at higher risk.

Prospective clinical observational study evaluating gender-associated differences of preoperative pain intensity

Previous studies reported conflicting results concerning different pain perceptions of men and women. Recent research found higher pain levels in men after major surgery, contrasted by women after minor procedures. This trial investigates differences in self-reported preoperative pain intensity between genders before surgery.Patients were enrolled in 2011 and 2012 presenting for preoperative evaluation at the anesthesiological assessment clinic at Charité University hospital. Out of 5102 patients completing a computer-assisted self-assessment, 3042 surgical patients with any preoperative pain were included into this prospective observational clinical study. Preoperative pain intensity (0-100 VAS, visual analog scale) was evaluated integrating psychological cofactors into analysis.Women reported higher preoperative pain intensity than men with median VAS scores of 30 (25th-75th percentiles: 10-52) versus 21 (10-46) (P < 0.001). Adjusted multiple regression analysis showed that female gender remained statistically significantly associated with higher pain intensity (P < 0.001). Gender differences were consistent across several subgroups especially with varying patterns in elderly. Women scheduled for minor and moderate surgical procedures showed largest differences in overall pain compared to men.This large clinical study observed significantly higher preoperative pain intensity in female surgical patients. This gender difference was larger in the elderly potentially contradicting the current hypothesis of a primary sex-hormone derived effect. The observed variability in specific patient subgroups may help to explain heterogeneous findings of previous studies.

Prevalence and Determinants of Depression and Anxiety Symptoms in Surgical Patients

OBJECTIVES

Mood disorders are prevalent in hospitalized patients. However, risk factors for early diagnosis have not been studied exclusively in surgical patients. Our study aimed to investigate the prevalence and determinants of depression and anxiety symptoms in surgical patients.

METHODS

We included 392 surgical patients in this prospective cross-sectional study, which took place between June 2011 and June 2012. The Hospital Anxiety and Depression Scale (HADS) was used to screen for symptoms of depression and anxiety at weekly interviews. Regression analysis was performed to identify risk factors for early (the day after admission) and late (one week or more) in-hospital psychiatry symptoms.

RESULTS

Depression and anxiety symptoms increased from the time of admission toward longer hospital stay. Scores obtained in the second and third weeks of admission were associated with the need for surgery while HADS in the third week was associated with lack of familial support and being under the poverty line (p < 0.050). Regression model analysis showed that early depression was associated with female gender, and early anxiety was inversely affected by female gender and protected by higher education level. A history of mood disorder was a risk factor. Later anxiety was also associated with longer hospital stay.

CONCLUSIONS

Depression and anxiety symptoms are a major concern in surgical patients especially in females and those with a history of mood disorders or lower educational level. Patients with a longer hospital stay, in particular, those with underlying diseases, postoperative complications, lack of familial support, and the need for reoperation were also at increased risk.

Preoperative biomedical risk and depressive symptoms are differently associated with reduced health-related quality of life in patients 1year after cardiac surgery

OBJECTIVE

To examine whether preoperative biomedical risk and depressive symptoms were associated with physical and mental components of health-related quality of life (HRQoL) in patients 1year after cardiac surgery.

METHOD

Seventy-five patients completed a psychological evaluation, including the Center for Epidemiological Study of Depression scale, the 12-item Short-Form Physical Component Scale (SF-12-PCS) and Mental Component Scale (SF-12-MCS), the Instrumental Activities of Daily Living questionnaire for depressive symptoms and HRQoL, respectively, before surgery and at 1-year follow-up.

RESULTS

Preoperative depressive symptoms predicted the SF-12-PCS (beta=-.22, P<.05) and SF-12-MCS (beta=-.30, P<.04) scores in patients 1year after cardiac surgery, whereas the European System for Cardiac Operative Risk Evaluation was associated with SF-12-PCS (beta=-.28, P<.02), but not SF-12-MCS (beta=.01, P=.97) scores postoperatively.

CONCLUSIONS

The current findings showed that preoperative depressive symptoms are associated with poor physical and mental components of HRQoL, whereas high biomedical risk predicts reduced physical, but not mental, functioning in patients postoperatively. This study suggests that a preoperative assessment of depressive symptoms in addition to the evaluation of common biomedical risk factors is essential to anticipate which patients are likely to show poor HRQoL after cardiac surgery.

Cognitive behavioral therapy in depressed cardiac surgery patients: role of ejection fraction

AIMS

The aim of this study was to evaluate the relationship of ejection fraction (EF) and depressive symptoms in cardiac surgery patients assigned to nurse-guided cognitive behavioral therapy (CBT) or usual care (UC).

METHODS

Depressive symptoms were assessed using the Beck Depression Inventory (BDI). Seventy-seven patients (31% women; mean [SD] age, 63.6 [9.8] years) received 8 weeks of either CBT or UC. Using repeated-measures analysis of variance, changes in depressive symptoms over time were evaluated.

RESULTS

There was a significant interaction among time, treatment group, and EF status (p = 0.019). In the patients with preserved EF (≥40%), mean BDI scores in the UC group worsened by 1.9%, whereas those in the CBT group improved by 31.0%. In the patients with low EF (<40%), mean BDI scores worsened by 26.8% and improved by 75.3% in the UC and CBT groups, respectively.

CONCLUSIONS

Nurse-guided CBT is effective in reducing depressive symptoms after cardiac surgery, particularly in patients with low EF.

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.

Depressive symptoms are associated with incident coronary heart disease or revascularization among blacks but not among whites in the Reasons for Geographical and Racial Differences in Stroke study

PURPOSE

To examine the association of depressive symptoms with coronary heart disease (CHD) end points by race and income.

METHODS

Study participants were blacks and whites (n = 24,443) without CHD at baseline from the national Reasons for Geographical and Racial Differences in Stroke cohort. Outcomes included acute CHD and CHD or revascularization. We estimated race-stratified multivariate Cox proportional hazards models of incident CHD and incident CHD or revascularization with the 4-item Center for Epidemiological Studies Depression Scale, adjusting for risk factors.

RESULTS

Mean follow-up was 4.2 ± 1.5 years; CHD incidence was 8.3 events per 1000 person-years (n = 366) among blacks and 8.8 events per 1000 person-years (n = 613) among whites. After adjustment for age, sex, marital status, region, and socioeconomic status, depressive symptoms were significantly associated with incident CHD among blacks (hazard ratio [HR], 1.39; 95% confidence interval [CI], 1.00-1.91) but not among whites (HR, 1.10; 95% CI, 0.74-1.64). In the fully adjusted model, compared with blacks who reported no depressive symptoms, those reporting depressive symptoms had greater risk for the composite end point of CHD or revascularization (HR, 1.36; 95% CI, 1.01-1.81). Depressive symptoms were not associated with incident CHD end points among whites.

CONCLUSIONS

High depressive symptoms were associated with higher risk of CHD or revascularization for blacks but not whites.

The Impact of Peplau's Therapeutic Communication Model on Anxiety and Depression in Patients Candidate for Coronary Artery Bypass

BACKGROUND AND OBJECTIVE

Anxiety and depression are among the psychological disorders in heart surgeries. Establishing a simple communication is essential to reduce anxiety and depression. Hence, the objective of the present studywas to examine the impact of Peplau therapeutic communication model on anxiety and depression in patients, who were candidate for coronary artery bypass in Al-Zahra Heart Hospital, Shiraz during 2012-2013.

METHODS

This is a clinical trial in which 74 patients were randomly divided into intervention and control groups, each consisted of 37 patients. Anxiety and depression levels were assessed before, and two and four months after intervention using the Hospital Anxiety and Depression Scale (HADS). Seven therapeutic communication sessions were held in four stages. Data were analyzed with the SPSS (version 16) using analysis of covariance.

RESULTS

The mean anxiety and depression levels decreased in the intervention group after the therapeutic communication (p<0.01). Anxiety scores in the intervention group before and after intervention were 10.23 and 9.38, respectively. While the corresponding scores in the control group were 10.26 and 11.62, respectively. Depression scores in the intervention group before and after intervention were 11 and 9.13, respectively. The corresponding scores in the control group were 11.30 and 12.08, respectively.

CONCLUSION

The results demonstrated the positive role of therapeutic communication in reducing anxiety and depression of the patients. Therefore, the therapeutic communication is recommended as a simple, cost effective and efficient method in this area.

Relation of major depression to survival after coronary artery bypass grafting

The primary aim was to study the association between preoperative depression and long-term survival after coronary artery bypass grafting (CABG). Our secondary objective was to analyze the association between depression and cardiovascular events or all-cause mortality. In a nationwide, population-based, cohort study, all patients who underwent CABG in Sweden from 1997 to 2008 were included from the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry. Individual-level data were cross-linked from other national Swedish registers. Depression status and outcomes were obtained from the National Patient Register. The study population was 56,064 patients who underwent primary, isolated, nonemergent CABG. We identified 324 patients (0.6%) with depression before CABG. During a mean follow-up of 7.5 years, 114 patients (35%) with depression died, compared with 13,767 patients (25%) in the control group. Depression was significantly associated with increased mortality and the combined end point of death or rehospitalization for myocardial infarction, heart failure, or stroke (multivariate-adjusted hazard ratios [95% confidence intervals] 1.65 [1.37 to 1.99] and 1.61 [1.38 to 1.89], respectively). In conclusion, we found a strong and significant association between depression and long-term survival in patients with established ischemic heart disease who underwent CABG. Depression was also associated with an increased risk for a combination of death or rehospitalization for heart failure, myocardial infarction, or stroke.

The effect of mindfulness training prior to total joint arthroplasty on post-operative pain and physical function: study protocol for a randomised controlled trial

BACKGROUND

Osteoarthritis is a leading cause of disability in developed nations. In Australia it afflicts 16.5% of the adult population. Total joint arthroplasty is considered the treatment of choice for end stage osteoarthritis. The number of total joint arthroplasties undertaken in Australia has doubled over the last decade (more than 80,000 procedures in 2011). The incidence of pre-operative psychological distress in this group of patients is reported between 30% and 60% and pre-operative psychological distress is associated with poorer pain and functional outcomes after surgery. This study will use a mindfulness-based psychological intervention to enhance outcomes in people undergoing total joint arthroplasty and, in addition, will test hypotheses about coping with chronic illness in an aged population. This study is the first of its kind and will provide a greater understanding of the role of a mental health enhancement program on the physical recovery of total joint arthroplasty patients.

METHODS/DESIGN

One hundred and fifty people with end-stage arthritis on the waiting list for total hip or knee arthroplasty will be recruited and randomly allocated to one of two groups using computer-generated block randomisation. A randomised controlled trial adhering to CONSORT guidelines will evaluate the efficacy of a mindfulness training program (weekly group-based classes in mindfulness practice, 2 ½ hours, for 8 weeks plus a 7-hour Saturday session in Week 6) prior to total joint arthroplasty, compared to a "standard care" group who will undergo routine total joint arthroplasty. Primary outcomes will be evaluated by a blinded examiner at baseline, 3 and 12 months post-surgery, using a validated self-reported pain and physical function scale. Secondary outcomes will include i) a range of validated measures of psychological wellbeing and ii) health economic analysis. All analyses will be conducted on an intention to treat basis using linear regression models. Health economic modelling will be applied to estimate the potential cost-effectiveness of mindfulness training and total joint arthroplasty.
